speclcatlon of Letters Patent.

Patented Mar. 19, 1918.

Application filed August 4, 1917. lcrlal No. 184,401.

To all 'whom it may concern:

Be it known that I, Houses G. MARTIN, a citizen of the United States residing at Rutherford, in the county of lergen, State of New Jersey, haveinvented a new and useful Improvement in Telegrapliic Sending-Machines, of which the following is a specilication. y

My invention relates to improvements in telegrnphic sending machines for sending messages, of the same general character and urpose as set forth in my prior Patents To. 842,154 dated Januar 22, 1907, and No. 1,043,44ii, .ined Novem er 5, i912.

, Referring to the drawings, Figure 1 is a front elevation of one embodiment of my improved telegraphic sending machine; Fig. 2 is a side elevation of the same, looking toward the left in Fig. 1; Fig. 3 is a sectional view on the line 3-3, Fig. 1, looking downward; Fig. 4 is a similar sectional view of a portion of the movin parts of the ap aratus, on the line 4 5, Fig. 1, present y to be explained; Fig. 5 is an oblique or dia onal view, artly toward the left and par y downwar Fig. 1, of the movin or operative parte of the aiparatus.

In t e preferred construction provide a metal base 1, having preferably four rubber feet, 2, which rest upon the table and keep the apparatus in equilibrium without the necessity of clamps` or screws. upright frame or base 3 is secured to the base 2 by screws 4, 4, Fig. 1, this construction being employed rathei` than that of casting the parts 1 and 3 integrally.

A shaft 5 is secured in the upright 3, on which is placed a main lever 6, capable of being moved from leftto right upon the axis 5. A ring 7, held inlace on shaft 5 by a locking screw 8, Fig. revents lever 6 from slipping oi said sha Two studs 9 and 10 are cast on upright 3. A screw 11 with lock mit 12 is inserted in lug 9, and a similar. screw 13 with lock'nut 14 is inserted in lu 10, Fig. 1, which screws a'nd nuts are a instable stops to control the movement of the upper end of lever 6 from left to right. The upper end of lever 6 iis normally held against stop 11 by a spring 15 near its lower end, whose tension can be varied by means of a screw 16 and thumb nut 17.

` right 3 by -cured to sai A shaft 18 is secured in lever 6 near its upper end, which serves as an axis on which to move a hand lever 19 to the lower end of which pieces of insuiating material 20 are secured by a bolt 21 for operating the apparatus and in the upper end of which is inserted a screw 19. A lug 22 projects from the side of lever 6 (side view, Fig. 2, end view, Fig. 1), against which the lower end of lever 19 is normally held b a spring 23, bolt 24, and the tensioning t umb nut 25. These parts are illustrated in greater detail in Fig. 4.

In the upper end of lever 6 is secured a Hat, vibrator spring 27,-Seen sidewise in Fig. 2 and edgewise 'in Fig. 1. To the other end of spring 27 is secured a vibrator bar 28, whose up er end normally rests against alu 29, pre erably integral with upright 3. O n ar 28 is a weight 30 which is he d on the bar by two pins 31, 'but is capable of being moved to and held in any desired position up or down said bar by means .of the thumb screw 32, Fig. 1.. To bar 28 is fastened in any convenient manner a small metal piece 33, to which 'is secured a at sprin 34, parts 33 and34 being seen sidewise, ig. 2, and edgewise, Fig. 1. Spring 34 carries at its upper end a contact point 35.

A binding ost (see Fig. 2)is secured without insulxiition to the rear side of upmeans of a thumb-nut 41 for attaching an electrical conductor 42. A second binding post 43 is likewise secured to upright 3, but insulated therefrom, for securing a second electrical conductor 44. Post 43 and the 'manner of securing the same to and insulating it 4from part 3 are shown in greater detail in Fig. 3. Said post gasses through a bushing 4 5 and wash-Y ers 4 ,46, of insulatin material, preventing contact between sai post and upright 8. A switch contact 47, Fig. 3 (dotted ines, Fig. 1), is also 'inserted on post 43, and the parts are heldl together by washer 43 and nut 49. Th electrical conductor 44 is sepost by thumb nut 50. At the other end of post 43 s a screw 5.1 which may be held in any position to which it. is moved by the thumb-nut 52, and it has inserted in Vits end a suitable contact point 53. A switch 54, having an insulated handle 55, is secured to the rear side of upright 8 by a GIS bolt 56 and spring 5'?, Figs. 1 and 2. When current Hows through the ,mechanism be- 35 said switch is open, Fig. 1, the apparatus tween conductors 42 and 44 in the manner is operative; but when it is closed, Figs. 2 pointed out' above.

In a telegraphic sending machine, the indicated by the arrows, when the operator combination of a base, a shaft secured to desires to send a message, he moves hand the base, a main lever rotating on said shaft pieces 2O and the lower end of lever 19 to a shaft secured to said main lever, a han the left, Fig. 1, compressing sprin 23, and lever rotating on said shaft and havin the upper end of said lever to tie right means for its operation located between sai said lever revolving on axis 18. B sai shafts, a vibrator mechanism attached to movement screw 19", which may be a justed said main lever and adapted to vibrate after to the riht or left as desired, striking the said main lever has come to rest, an electriupper en of spring 34 moves it to the right cal contact secured to and insulated from 35 and brings the contacts 35 and 53 together. said base, an electrical contact operated by The circuit is thus closed, and the current movements of said vibrator mechanism, and 'flows through the machine b, way of.con means whereby said main lever and said viductor 42, upright 3,A shaft 5, ever 6, spring brator mechanism may be operated by move- 27, bar28, part 33, sprin 34, contacts 35, ment of the hand lever in one rdirection to 53, screw 51, .post 43 an conductor 44 to eiect a series of makes and'breaks between the line.
