MEANS FOR POSITIONiNG AND FIRING HEAVY ORDNANCE.
SPECIFICATION forming part of Letters Patent N 0. 691,254, dated January 14, 1902. Application filed January 12, 1899. Serial No. 701,898. (No model.)
To all whom it may concern.-
Be it known that I, THEODORE MARSHALL FOOTE, a citizen of the United States of America, residing in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Means for Positioning and Firing Heavy Ordnance, of which the following is a specification.
My invention relates to means for positioning ordnance preparatory to its being fired andalso to means for firing the ordnancepiece. The firing of the ordnance-piece may be accomplished immediately after its being positioned.
I will describe an arrangement of mechanism embodying my invention and then point out the novel features in the claims.
In the accompanying drawings, Figure 1 is a View, partly in elevation and partly in section, of the mechanism for positioning and firing an ordnance-piece embodying my invention and showing in diagram electric circuits which control such mechanism. Fig. 2 is a top view, partly broken away, of a portion of Fig. 1. Fig. 3 is a vertical longitudinal view of a clutch device used in the mechanism Fig. 4 is a transverse sectional view taken on the line 4 4-. of Fig. 3. Fig. 5 is a transverse sectional view taken on the line 5 5 of Fig. 3. Fig. 6 is a detail elevational view of a portion of a sighting means and adjacent parts. Fig. 7 is a top view of Fig. 6, showing the full sighting means and showing a portion of an ordnance-piece trunnion and its connection to the sighting means. Fig. 8 is a transverse sectional view taken on the line 8 8 of Fig. 6. Fig. 9 is a detail vertical sectional view showing, on an enlarged scale, the connection between the trunnion of the ordnance-piece and the sighting means.
Similar letters of reference designate corresponding parts in all the figures of the drawings. A represents a turret; B, an ordnance-piece, heav gun, or cannon that is mounted by its journals bin the carriage O. The carriage is here shown as being located within the turret. The ordnance piece is adapted to be moved in two directions, both vertically and laterally, the movement in a lateral direction in thisinstance being accomplished by revolving the turret. If desired, however, the carriage C may be swung or revolved so as to move the ordnance-piece in the opposite lateral directions. The vertical and lateral movements may be made either separately or simultaneously. Should the ordnance-piece be moved vertically and laterally simultaneously, the direction of movement of the ordnance-piece would be oblique to the vertical and horizontal planes of movement of the ordnance-piece.
D represents a sighting means, in this instance shown as a telescope, which is so mounted that it can be adjusted vertically and laterally or in directions oblique to either its vertical. or lateral planes of adjustment, and it is by the adjustment of the sighting means that a mechanism or mechanisms are set in operation to position the ordnancepiece for firing. The telescope may be mounted in the following manner to have vertical,
lateral, and oblique adjustments: The telescope is rigidly held in the cradle d, that is carried by a bail cl. The bail d is pivotally mounted in a second bail 01, and the bail d is provided with a projection (1 fitting within the sleeve or socket formed in the standard d. The standard may be secured to any desired support--as, for instance, the car- 1 riage O.
The mechanism employed for moving the ordnance-piece in either a vertical or a lateral direction or both directions is preferably electrically controlled. As the telescope is adjusted in any direction it causes a controller or controllers to open or close a circuit or cir cuits of a device or devices which control the operation of the positioning mechanism. The form of controller preferably employed in the vertical adjustment consists of a metallic ring in two sections 01 d, which sections are carried by a disk (1 and a contact-finger as to be rotated thereon, but prevented from having any sidewise or lateral movement on the trunnion d. The disk d is operatively I key E extends.
connected with the trunnion of the gun in a manner to be hereinafter explained. Aprojection d integral with an arm (1*, that is loose on the trunnion (Z carries the contactfinger (Z The end of the contact-finger d is adapted to rest normally over the insula tion d between the ends of the ring-sections, so that the circuit of which the contact-fingerforms a part will be open, and it is adapted when the telescope is adjusted vertically to travel over one or the other of the ringsections, and thus close the circuit which controls the mechanism for moving the ordnancepiece vertically. As this mechanism is operated the trunnion of the ordnance-piece turns, and through the medium of a connect-ion between it and the disk d the disk c is made to turn with it until the insulation d again comes under the end of the contact-finger 61 when the circuit will become broken and the mechanism of that circuit stop from operating. The connection between the trunnion of the gun and the disk 616 (designated by the letter E) comprises a universal joint E and a telescoping portion. (See Fig. 9.) The part E of the connection on one side of the universal joint is fixed to the trunnion of the gun, while a part E on the other side of the universaljoint is adapted to slide in and out of the extended trunnion al The extended trunnion d and the part e are here shown as constituting the telescoping portion of the connection E. The part E is provided with a longitudinal groove E in which a pin or The pin or key E is fast to the disk d It will be seen that the controller hereinbefore described constitutes a make-and-break or other device, which when it is actuated by the telescope will cause the mechanism to operate to position the ordnance-piece for firing and also will act to cause the mechanism to cease operating when the ordnance-piece is moved to a position parallel or approximately parallel with the telescope. In this manner the telescope may be fixed on an object and held fixed while the mechanism is operating to move the ordnance-piece to be pointed at the same object, and when the gun is pointed at the object the mechanism will cease operating. It will be seen also that the slightest movement of the telescope actuates the controller, and the slightest actuation of the controller causes the mechanism to operate or further move the gun. In this manner the ordnance-piece is accurately pointed at the object. The vertical adjustment of the telescope does not, however, always give the exact firing elevation of the ordnancepiece-as, for example, when a projectile or shot is to be thrown a long distance. The ordnance-piece in such case should not be in parallelism with the telescope; but it should be inclined above the longitudinal plane of the telescope when it is sighted upon an object to be fired at. The correct firing elevation is preferably accomplished by means of 'ard 61 a pinion d ,journaledin the arm (1* and engaging with the disk or segment of a disk (Z that is calibrated according to the elevation desired for the ordnance-piece to send a projectile an ascertained distance. The disk or segment of a disk 61 is fastened or connected in any desired manner to the cradle d, and when the telescope is adjusted vertically the disk or segment of disk 61 will move with it.
The pinion cl and the teeth on the part d serve as a connection between the part (Z and the arm (1*, thus enabling the telescope to move the arm (1* with it. The arm 61*, however, can be moved independently of the telescope, owing to its being loose on the trunnion (1 When the distance of the object to be fired at is ascertained, the pinion is made to travel over the calibrated disk until it reaches the point on the scale of the disk indicating the ascertained distance. The part d traveling over the part 61 carries with it the arm d and contact-finger d which is then moved over one or the otherof the ringsections. The circuit will then be closed and the mechanism for moving the gun vertically permitted to operate. As the ordnance-piece moves, its trunnion, through the connection E, turns the disk d to move the insulation between the ring-sections under the end of the contact-finger to break or open the circuit, as hereinbefore described. The mechanism then stops operating and the ordnancepiece is held in its position. The telescope is then adjusted vertically (should it be necessary) to be fixed on the object, and as the telescope is moved the contact-finger is again moved onto either of the ringsections to again close the circuit and permit the mechanism to work, thus accurately putting the ordnance-piece in position with regard to its elevation. The universal joint E in the connection E permits of the disk d being operated in the vertical adjustment of the ordnancepiece should the telescope be adjusted laterally to move the ordnance-piece in range in that direction before its vertical adjustment, and vice versa. The same form of controller is presumably used in connection with the mechanism for moving the ordnance-piece in a lateral direction. The contact-finger of the controller is carried by a projection (Z on the bail (Z so that as the telescope is adjusted laterally it will travel over either of the ring-sections d 61 and thus close the circuit of the device that effects the operation of the mechanism for moving the ordnance-piece laterally. The ring-sections of the controller are secured to a disk al carried by a sleeve d", surrounding the stand- When the contact-finger is moved over either section of the ring, the circuit of the device effecting the mechanism for moving the ordnance-piece laterally is closed, thus permitting the operation of this mechanism. In this instance the carriage is fixed to the turret, which is made to revolve. As
the carriage is revolved with the turret and IIO - the telescope held fixed upon the object, the
disk will travel under the end of the contactfinger until the insulation betweenthe ringsections comes under its end. YVhen' this occurs, the circuit will be broken, thus controlling the device to effect the stoppage of the mechanism. The ordnance -piece will then be parallel to the telescope. A calibrated disk and pinion, as described in connection with the diskd will also be provided in connection with the disk d. The calibrated disk in this instance is used to compensate for the speed of the object to be fired at, as well as the support carrying the ordnance-piece,should it have any speed, and also for windage.
The devices for controlling the operation of the mechanisms for moving the ordnancepiece vertically and laterally are electrically controlled. Each device preferably comprises two electrically-controlled clutches J J, and each clutch comprises a revolving gear, a casing carrying the operating-magnets loosely mounted on a power-shaft K, and a friction-pulley keyed on said shaft. The magnets of each clutch are preferably included in separate circuits, which circuits are opened and closed by one of the controllers when actuated by the adjustment of the telescope. The circuits of both electrical devices are preferably the same, so that a description of the circuit-as, for instance, the circuit of the electrical device controlling the mechanism for moving the ordnance-piece vertically-will apply to the circuits of the electrical device controlling the mechanism for moving the ordnance-piece laterally. The circuit or circuits of the electrical device controlling the mechanism for moving the ordnance-piece vertically may be as follows: A wire f, leading from one pole of a battery F, is connected withthe contact-finger d ,while the other pole of the battery is connected by wires ff with the ring-sections d (l on the disk (1 Electromagnets f are included in the connections ff so that when the contactfinger d is moved onto either of the ringsections 61 01 either magnet will be energized, according to which ring-section the finger d rests upon. Movable arms f ffiwhich serve as armatures for these magnets, form part of two other circuits which are opened or closed by their armatures, according to which magnet f f is energized. The magnet in the circuit of each part of each controller and its movable armature serves as a make-andbreak. I wish it understood that any other form of make-and-break that will serve the same purpose may be employed. It will-also be seen that the make-and-break constitutes means which when operated will control the mechanism for positioning the ordnancepiece for firing. One part of the make-andbreak may be operated by the telescope and the other part by the ordnance-piece. The armatnresf f are connected by a wire g or other conductor, and this wire is connected by a wire or conductor g with one pole of a battery G. The other pole of the battery G is connected to the wire g near one terminal of the wiring of the magnets of one of the electrical clutches, while a wire g connects the same pole with one terminal of the wiring of the magnets of the other electrical clutch. A wire g is connected with the other terminal of the electromagnets of the clutch with which the wire g is connected and with the contact-point g ,with which the armature f engages when attracted by its electromagnet f The same wiring and arrangement are provided for the other magnets of the clutch. It will be seen, therefore, that either of the electrical clutches will be operated according to whether the contact-finger cl is on the ring-section d or (1 The same arrangement of circuits is provided in connection with the controller of the electrical device controlling the mechanism for moving the ordnancepiece laterally, and the same form of electric clutch is used. .In Fig. l I have shown the two circuits connected by means of a wire or other connection H, extending between two contact-points 7L 71 that are included in the separate circuits. This wire forms part of the firing-circuit h. The
firing-key H is preferably located on. the telescope, so that when the ordnance-piece has been properly positioned it can be fired from the telescope. The firing-circuit includes a firing device if on the ordnance-piece, a battery h, and two contact-points h h, which are also included in the circuits of the two controllers actuated by the telescope. -It will be seen that to have the firing-circuit complete the a'rrnaturesf and f in each of the circuits will have to be in engagement with the contact points It and h in the two circuits. These armatures are only in this position when the contact-finger of each controller is on the insulation between the ring-sections. As the telescope will always be fixed onthe object should it be moved either vertically or laterally, either armature f or f in either circuit will be attracted to its magnet and the firing-circuit broken. It will thus be seen that the ordnance-piece cannot be fired until it is ranged directly on the object.
The clutches J J are geared to a dynamo or other motor I, which when the ordnance the shaft K, which is journaled in standards Each gear j j carries a cylindrical casing f, which casings are so arranged at their meeting edges as to afford a bearing for each other. In each casing a support 7' is provided for the electromagnets L, contained therein. The armature j for the magnets in each part of the clutch is pivotally hung from one end of a linkj which is hinged at its other end to the gear. It will be seen, therefore, that as the gears j and j are rotated the magnets, with their armatures, are carried with them. A band 9 carried by each gear j j, surrounds a friction-pulley M in each part of the clutch, and each band is made to embrace the pulley it surrounds by the armature of the magnets in that part. The roller or other device 3' carried by the linksj may be used to force the band against the pulley. When, therefore, the armature of the magnets in either part is'attracted, the pulley M in that part will turn with the gear. The pulleys M are fast on the shaft K, so that as either pulley M is turned the shaft will be turned. On the collar of each gear j j is fixed a sleeve of insulation j and fixed on these sleeves are two rings f. The terminals of the electromagnets L, comprised in each clutch, are connected with these rings, Contaot-fingers 3' carried on a projecting part of each standard it, engage with these rings, and it is with these fingers that the wires 9 g of each circuit are connected. A springj holds the links j normally against stopsj (See Fig. 3.)
The ends of the shaft K of the electrical device which controls the mechanism for moving the ordnance piece vertically are provided with pinions 70 which mesh 'with gears 70 carried bya shaft 70 This shaft is journaled in the standards 70, which may be extended for this purpose. Pinions is engage with the racks 70 that are aflixed to the gun. The shaft of the electrical device which controls the means for moving the ordnance-piece laterally is provided with a beveled pinion k on one of its ends, which is in engagement with a bevel-gear 7c. The bevelgear k is provided with a pinion k engaging with teeth provided on the turret. If desired, the mechanism for moving the ordnance-piece may be connected directly with it.
