Application filed May 10,

My invention relates to improvements in telegraphing machines and more particularly to machines for sending code messages.

An object of new invention is to provide a machine in which relatively movable code signal contacts in an electrical circuit are arranged for actuation by letter designated key levers.

A further object is to provide a machine comprising a typewriting machinehaving a lettered keyboard and a code sending machine coupled for operation with the writing machine whereby as a typewritten copy is made a code message is sent as an exact duplicate of the written copy.

My improvements consist in the novel construction, arrangement and combination of parts as hereinafter fully, clearly and concisely described, definitely pointed out in my claims and illustrated by the accompanying drawings, sheets) in which Fig. 1 is a front elevation of the telegraphing machine of my invention;

Fig. 2 is an end elevation of the machine shown in Fig. 1, showing its relation to a typewriting machine, which latter is shown only fragmentarily;

Fig. 3 is a detail perspective of one of the code wheels; 2

Fig. 4 is a detail sectional elevation, taken on the line 44 of Fig. 2 showing the rela' tion of the actuating levers of the telegraphv ing machine with the key levers of a typewriting machine;

F g. 5 is an enlarged elevation showing several of the code elements, one of which is shown in vertical section, and another of which shows a key actuating member;

I Fig. 6 is a transverse section taken on the line 66 of Fig. 5;

, Fig. 7 is a section taken on the line 7-7 of Fig. 5 showing a relating means for the relatively movable code contact elements.

Referring more specifically to the drawings, A designates a frame comprising a base 10. spaced standards or cheeksll, a driven shaft 12, a shaft 13 for the support of the actuating levers and an insulating guide bar'14 for certain of the actuating mechanism. I

The shaft 12 is arranged for constant rotation and the gear wheel 15 represents one of a train of reduction gear elements for connection with a motor not shown. Mounted on the shaft 12 is a plurality of code wheels 1926. Serial No. 108,017.

16, which as shown in Fig. 3, comprises a periphery composed of relatively insulated code contacts 17 and the wheel is fixed for rotation with the shaft as by a pin 18.

Embracing and surrounding each code wheel is a disc-shaped body 19 of insulating material, which is loosely rotatably carried on the shaft 12, in whose one lateral face is a depression 20 to receive the code wheel and through which from the periphery to the depression is formed a bore 21.

In the end of the bore next the periphery is fitted a metallic seat 22.

A brush 23 is placed in the borefor engagement with the code wheel, a'coil spring 24 placed next the brush and an adjustable spring abutment 25, formed as a screw plug,

. is fixed in the seat 22.

A band 26 of metal is placed around each of the disks 19 with its free ends extended therebeneath and between which'is detachably secured as by a bolt 27, a tubular fitting 28. Into this fitting a headed bolt 29 is slipped and extended through the guide bar 14.- p

Mounted on the shaft 13, carried in bearings 30, which are insulated from the frame, as by the blocks 31, is a lever 32, for each band 26, which lever straddles the bolt 29, as best shown in Fig. 5 and which boltcarries an adjustable nut 33 which serves to I pull the band upon a depression of the lever.

A restoring spring 34 impinging between,

the guide bar 14 anda nut 36 carried on the bolt is provided for each lever 32.

holding of the bands properly related.

In Fig. 2 the fragmentary bar-shaped element B represents a typewriting machine of any standard design and such fragment is'the showing of one 'of the key levers, which connects with an actuating lever 32 of thetelegraphing' machine, such as in Fig. 4, in a manner to depress the lever 32 upon a printing movement of the key lever of the typewriter.

In order that the brush 23 be held in proximal relation to the code contacts 17, lprovide a locator which comprises a tripper arm 38 rotatable with the'code wheel and a spring held detent 39 carried by the discbody 19, which operates to normallyposition the brush away from the contacts 17 as shown in Fig. 6, but which upon a stoppingof the disk body, as by an action of a band, as a' brake, releases the code Wheel from the brush carrying body 19 .so that in l the continued movement of the code-Wheel code'contacts Will belldeliveredr from the points 17 to the brush; I

Y In operation, upon the depression ofia lever 82-, the band is tightened about a'disc l9 andthe brush stopped, so that the rotating c odewvheel Will deliveran interrupted cur rent to the brush'a-nd over slim to a standard telegraph receiving set. V 7 I 7 By tightening the bandQG about the rotat- ,ing brush-carrying disc 19 relative motion is produced between theselective code Wheel 7 and contact in such a' small fraction ofa seccontact.

In devices or this class wherein pawls and ratchets are employed, accuracy of transmis sion under high speed is interfered with. If an unyielding stop is suddenly thrown into the path of a rapidlyrotatin element,
