JOHN L. HALL, OF SCHENECTADY, NEW YORK, ASSIGNOR TO GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK.
CONTROL SYSTEM FOR SEARCH-LIGHT PROJECTORS= Specification of Letters Patent.
Patented June 5, 1906.
Application filed November 15, 1902. Serial No. 181,549.
. ectady, county of Schenectady, State of New York, have invented certain new and useful Im rovements in Control Systems for Search- Lig t Projectors, of which the following is a specification.
This invention relates to a system of control for a search-light projector, and has for its object the regulation of the direction of the beam of light in altitude and azimuth either se arately or simultaneously by a single hand e placed at a distance from t e projector.
As used on shipboard search-lights are often placed far forward in an elevated position where the beam of light would be unobstructed, and the direction ofthe beam is controlled from the bridge or some other point at a distance from the projector. For
this purpose systems of rope-gearing have been employed by whichropes or cables transmit the movements of a handle mounted at the oint of control to mechanism regulating the direction of the beam of light.
My invention relates to rope-control s stems of the character above described. ts object is to simplify and cheapen the construction of the controlling device and to provide mechanism such that the movement of the projector is always under the direct and positive control of the operating-handle. To this end I provide which the projector is to be trained mounted on a universal bearin and connected posi-' tivel by ropes or cab es with the rojector, whic when shifted to the right or eft trains the beam in azimuth without possibility of lostmotion and when raised or lowered effects a similar training in altitude. For simplicity of construction pulleys are employed to transmit the operatin power to an from the'rope. On account 0 its large moment of inertia the projector resists the pull of the rope or belt on the pulleys, and the former tends to slip without impartin completely the motion of the handle to t e projector, and when moved it tends to continue its turning motion even after the operator ceases to move the handle, the belt shpp' g on the ulleys. If the belts had become stretched by the action of the weather on themor had bea handle at the point from' come slack from any other. cause, this slipping would occur to even a greater extent, so
that it would be difiicult to maintain the aparatus in proper working order. I thereore clamp the belts to each of the pulleys,
thereby preventing them from slip mg and provide turnbuckles in each side 0 the belt or taking up slack. In this way slipping is avoided and the projector is trained in exact accordance with any movement of the operating-handle.
The two ropes clam ed to the handle pass over guide-sheaves an out to the projector, where they pass over acommon pulley and are fastened to a rod movable vertically within the hollow shaft and extending upward through the base of the projector. An u ward or downward movement of the han le thus causes a corresponding vertical move- ,ment of the rod, which by means of a crosshead mounted at its upper end above the base and linked to the projector at points eccentric to its pivots trains the projector in altitude. The ropes being clamped to both the handle and the reciprocating rod, and turnbuckles being provide in each rope for taking up slack, the projector is caused to turn on its horizontal axis whenever and it cannot turn except when the handle is moved i A diagonal movement of the handle in any direction 0 crates both of the controllingropes sim taneously and causes a corresponding diagonal movement of the projector.- In this way the projector can be trained to any desired angle both as to altitude and azimuth by a single movement of the handle, and, further, the handle always indicates the direction in which the projector is trained as the beam "of light is always thrown in a direction parallel to the axis of the handle.v My invention therefore comprises a control system for a search-light rojector containin a universally-mounted lever at the contro -point and flexible connections with the pro ector for communicating a positive movement 1n any direction. It also com prises more specific features which will be ereinafter more fully described and definitely claimed. j
The construction of my device will be the handle is raised or lowered v more readily understood by reference to the which is mounted at the point from which'it is desired to control the pgojector by bolts passing through the lugs X. Extending outward from the frame Fare the arms f f to the ends of which the frame K is pivoted by means of hollow pivots. In the preferred construction the frame K has the form of two parallel V-shaped bars connected together at their ends. The ulley B is rigidly mounted horizontally on t e frame K near one end thereof and concentric with the hollow ivots. The handle H has a head E in the orm of a semicircular sheave or sector with two parallel grooves cut in the curved ortion of its periphery and is pivoted onthe bolt A between the parallel sides of the frame K in such a position that a line between the centers of the hollow pivots would'be tangent to the curved'head of the handle. The handnut Oturns on the bolt A and is adapted to lock the handle H against vertical movement. The clamps c c are mounted on the sector E to clamp the ropes M M, which in the position shown pass around one-half of the sector E through the hollow ivots of the frame K and over the pulleys P mounted on the arms ff respectively, of the frame F. The pulley or sheave B has a helical groove cut in its periphery, and'the rope L runs in this groove and out. over a similar horizontal pulley or sheave B, keyed. to the hollow shaft G and on the clamps h b, respective y, which gri the rope L and prevent it from slipping. T e shaft turns 111 a bearing D, formedintegral with the frame D, mounted on the under side of.
the stand supporting the projector, and extends upwar through the pe ,e'stal N where it is secured to the turn-table N, which carries the arms in whichj the projector is trunnioned. This frame" supports the ulley or sheave I and has an extension which forms a guide D for the rod 0. The ropes M M pass over the pulley I through openings in the collars o 0 on the rod 0 and are knotted to prevent being drawn through; those openings. The rod 0 extends upward through the hollow shaft G and abovethe turn-table carries the cross-arm g, whi'c hifs 'connected by the links g g to the drum of the projector at a point to the rear of the trunnions by which the drum is su ported. Turnbuckles e e are inserted in eac side of each ropefor taking up slack.
It will thus be seen that any movement of the handle H to the right or left turns pulley B, and, 'by means'of belt L, the pulley B on ulleys. B B are the the shaft G, thereby training he projector in azimuth, and when the handleis raised or lowered the ropes M M are drawn in and let out, thereby raising or lowerin the rod 0 and training the projector in a titude. As the belts are clamped both at the projector and at the point of control, they cannot sli and the projector moves exactly in accor ance with the movements of the operating- .handle. When the handle is moved diagonally, both movements take place simultaneously, and the. projector is trained to a position corresponding to the position of the handle. The ropes can be made of any length, guide-sheaves being provided to guide them around obstructions, so that the handle at right angles to the axis of said frame, a
sector mounted concentric with said handle and movable therewith, and flexible connections between said sheave and sector and the projector.
2. The combination with a search-light projector, of means for controlling the same comprising a-main frame, an operating-handle pivoted therein for movement in two planes at an angle with each other, a sheave mounted concentric with each axis of said handle and movable therewith, correspond inglyarranged sheaves on said projector, and flexible connections between the pairs of sheaves.
3. Controlling-gear for search-light projectors, com rising a handle having a curved end mova ly mounted on a frame pivoted on hollow pivots in a stationary frame, and a fle'xible connection clamped to said handle and passin through sai hollow'pivots, the ends; of sai flexible connection being secured to a reciprocating rod connected to the projectorat a point eccentric to its horizontal axls.
4. Acontrolling device for search-lig'ht projectors, comprising a handle having a curved end movably mounted on a frame pivoted on hollow pivots in a stationary frame, said movable frame' being so shaped that theaxis on which it turns is tangent to the curved end.
5. In combination with a search-light procurved head of the handle, means 0 erated by the handle for turning a hollow s aft se= cured to the projector turn-table, and a belt In witness whereof I have hereunto set my clamped to the handle passing over a portion hand this 14th day of November, 1902.
