Specification of Letters Patent.

Patented May 12, 1914.

Application filed August 2E', 1912. Serial No. 717,297.

T0 all whom it may concern Be itknown that I, ANGELO PARoDi, a subject. of the King of Italy, and a resident of the city of New York, borough of Manhattan, in the county and State of vNew York, have invented a new and Improved Telegraph-Receiver, of which the following 1s a full, clear, and exact description.

This invention relates generally to telegraph receivers, and is directed to a system of coperating elements whereby the structure is adapted to actuate other elements, whereby messages may be received' through the sensations of hearing and sight.

The primary object of,the invention disclosed is the provision of a telegraph receiver adapted to record messages on a Acontinuous tape, the construction being characterized by a. new and improved means for feeding the tape.

Other advantages following the use of the construction described and claimed will appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this speciication, in which like characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a side view of the receiver adapted for printin telegraph symbols on a continuous tape; Fig. 2 is a vertical sectional view thereof on the line 2-2 of Fig. 3; Fig. 3 is an end view from the right of Fig. 1; Fig. 4 is a sectional view showing details of the magnetically controlled lever; while Fig. 5 is a sectional view of the pen and ink container.

lThe receiver comprises a base 1 of any suitable material and size, provided with pairs of spaced uprights 2--3 and binding posts 4, together with electro-magnets 5,

these parts being not essentially different from the parts used-in telegraph receivers at present.

Referring particularly to Fig. 4, the lever 6 is recessed as at 7 on its under side, and within this recess is a second lever 8, the first lever 6 carrying an armature 9 and the second lever 8 having a pin 10 extending upwardly therefrom and carryinga second armature 11 adjustably mounted on the pin by means of screw threads, the position of the armature being maintained by means of a lock nut 12. These levers 6 and 8 are ivotally mounted on a transversely exten ing pin 13. The oppositely positioned uprights 2 are pro-vided with transversely extending screws 14 carrying lock nuts 15 and forming bearings for this pin; referring particularly to Fig. 3, it will be noted that a bifurcated arm 16 st-raddles the said levers 6 and 8, the particular urpose of which willbe presently set fort From this description it will be observed that the levers 6 and 8 are movable relatively to each other about the pin 13, and that the levers and the bifurcated arm 16 are movable relatively to the uprights 2.

Extending upwardly from the base of the instrument are ears 2O having screws 21 extendingtransversely thereof provided with lock nuts 22, and pivotally supporting the arm 23 adjacent its lower end, the lower end of the said arm being made up of spaced members 24; referring particularly to Fig. 2 it will be noted that. adjacent the lower end of this arm 23 is an element4 19 provided with a pocket 25 containing a helical spring 26, and that the lower end of the said arm 23 is provided with a shoulder 27 having a screw 28 extending transversely thereof and engaging the said helical spring 26, whereby a certain variable ,pressure may be applied to the lower end of the said arm. The upper end of vthis arm is pivotally .engaged at 29 with a link 30, the other end of the link being pivotally engaged at 31 with the upper end of the bifurcated arm 16 previously described. Extending between the lower end of the arm 23 and the adjacent end of the lever 6 is a link 32, in pivotal engagement with these .elements at 33-34,. the said link being adjustable in length by means of a turn buckle 35, the lower end of the link comprising spacedl sides 36, engaging the offsets 23a carried by the arm, whereby a continuous passageway is provided between the spaced portions 24 of the arm 23, the spaced sides of the linkwill attract the the openings and bearing against them,

whereby friction is materially reduced. Adjacent one end of the rod 38 is a table 40, ontop of `which a continuously extending tape 41 is adapted to be passed, the top of the table being provided with a transversely extending bearing portion 42, the table supporting a pivoted member 43 at 44, the lower end of the member being provided with an arm 45 adapted to come adjacent the said support37 when the rod 38 moves in one d irection, this said pivoted member being in pivotal engagementat 46 with one end of a bifurcated link 47, the other end of which pivotally engages the lower end of the bifur` cated arm 16 at 48. Since the tendency of the lever 6 is'to remain in uppermost position, as shown' in Fig. 1, when no current is flowing through the electro-magnets 5, due to the pressure of the helical spring 26 acting on the screw 28 carried by the arm 23 which is articulated with the lever 6, the normal position of this table then is as shown in Fig.

1, beingadapted to travel the distancebetween the position shown in Figs. 1 and 2 when the lever 6 moves downwardly'under the niuence of the magnetic field set up by the electro-magnets; while the table 40 is bein moved from one position to the other t e force which brings about A'the movement is communicated at the ivotal supporting point 46 which is below tie pivotal' point 44, so vthat the table-will move relatively tol the tape 41 without moving it, since the pivoted member 43 is brought re- .mote from the under side ofthe tableyon the return movement of the table, however, the forward-,portion of this pivoted member 43 engages the under side of the tape which is held adjacent ythe bearing portion 42, the tape being thereb fed forwardly on the'- return movement o thel levell 6 from the position shown inFig. 2 to that shown in Fig. l. j v

Referring still to Figs. l and 2 it will be noted that beneath the lever 6 and lpivotally supported at to the said su port 37,'is a secpnd table 51 the top 52 of w ich is curved on the arc of a circle with the said pivotal support 50 as-acenter, the said tape 41 eX- tending over this'curved top; the table is maintained normally in the position shown in Fig. 1 by means of a helical spring 53, certain means, however, being provided for bringing the table into the position shown in Fig. 2, such means embodying the following elements :-Referring to Fig. 4, it will be noted that the second lever 8, which is contained within the recess 7 on the under lside of the first lever 6, is held within the said recess by engagement with the pivoted element 54, one end of which is provided with an adjustable screw 55 the end of which engages with a helical spring 56 contained within a recess 57 in the end of the lever 6, pressure of the spring bringing the adjacent ends of this lever 8 and element 54 into uppermost position, which is' shown in Fig. 1; this element 54 is provided with an opening 58 through which a pen 59, to be presently described, extends, the lower end of the pen coming adjacent the tape 41 and on top of the said curved table 52, whereby an impression or mark is left on the tape. The pen comprises the pen roper 59 having an opening extending t ierethrough within `which some` absorbent material 60 is contained, the upper end of the pen being enlarged as at 61 and containing a quantity of inked absorbent material 62, these partsbeing contained within a receptacle 63 having a removable cover 64, a helical spring 65 being positioned within the receptacle and bearing against the said absorbent material in order to bringvsufiicient pressure to bear to cause the ink to flow to the point of the pen; the pen is adjustably mounted with respect to the lever 6 by screw threaded lengagement therewith, and is held in desired position thereon by means of a lock nut 66.

Pivotally supported at 67 adjacent the curved top 52 of the table 51 is a freely movable member 68, the lower end of which rests on top of the tape passing over the table; from an inspection of Fig. 4 it will be noted that if, after the pen 59 is brought adjacent the tape, the lever 8 is moved downwardly, the engagement between the projection 8? of this lever and the top of the said member 68, which engaging portions are inclme-d asvshown, will cause movement of the table 51 relatively to the pen 59, with the lower end of the member 68 in engagement with the tape so that the tape and table are moved bodily with respect to the pen, which leaves a line of certain length on the table. It will be noted that where the tape 41 enters the receiver from the left it passes over a rest 70, there being a gripping element 71 pivotally mounted adjacent` one end at 72 bearingl onvtop of the table, so that movement t ereof toward the right is freely permitted, movement of the tapete the left, however, being prevented.

The method of operation of the parts shown is as `follows: With the relative arrangement shown yin Fig. 1, if a current is passed through the winding of the electromagnets 5 of momentary duration, that is, no longer than to indicate a dot in the Morse up a fresh unmarked l neath the pen. The said armatures 9 and. 11 will not move downwardly simultane-V of contact with the end of the said pen; If, f

however, the circuit through' the electromagnets 5 is closed foi-an appreciable length of time, that is, long enough to indicate a dash in the Morse code, the first tendency of the .magnetic field' is to bring the lever 6 downwardly adjacentthe tape 4,1,.the tape feeding elements moving to the left as before and gripping the tape, the next stepl beingthe downward movement of the second lever 8 under the influence of the said magnetic field on the second armature 11, as shown inFig. 4, the downward movement of this second lever moving the pivoted table 51, and with it the tape, the tape being in contact with the pen, the result being the formation of a line of certain length, that is, afdash on the said tape; when the circuit is opened the pen is brought away from the tape and the'tape feeding mechanism brings ortion of. tape beously dueto the fact that the parts possess some inertia, and also because of the second air gap between the said armatures independent of the air gap between faces of the electromagnets and the first armature. The distance through which the lever 6 will travel before the pen strikes the tape may be adjusted in the usual manner by means of a set screw carried by the'uprights 3 and provided with a lock nut 81 for retaining it in any desired position. By means of the screw 28 andthe helical spring 26 the force necessary to move the various parts may be closely adjusted so that excessive force is not necessary the counterpoise 100 carried by the upper end of the arm 16 tending to ease of operation. Finally, the arrangement of the various parts provides a printing telegraph instrument in which the symbols of the code in` dots and dashes are set forth on the tape, the tape feeding forwardly only when required, and without any attention from an attendant.

Itis clear, of course, that a practical embodiment of the invention may assume a form quite different from that herein'sliown; such change in form, however, together with the choice of'materials used in the manufacture of the structure are contemplated within the spirit and scope of the appended claims.
