GEO GE L'ITTLE, or RUTHERFORD PARK, NEW JERsEY.
IMPROVEMENT IN AUTOMATIC TELEGRAPH INSTRUMENTS.
' Specification forming part of Letters Patent No. 122,473, dated January 2,1872.
To all whom it may concern:
Be it known that I, GEORGE LITTLE, of Rutherford Park, in the county of Bergenand State of New Jersey, have invented an Improvement in Automatic Transmitting and Receiving Telegraph Instruments and the follow ing is declared to be a correct description ofv the same.
This invention relates to the instrument em- In the drawing Fi gurel is an elevation of the instrument, with the rollers and trough in section to show th e paper,the transmitting portions being in position for operation. Fig.2 is a section detached, showing the transmitting mechanism thrown back ready for the paper to be inserted; and Fig. 3 shows the rollers and transmitting mechanism by a plan view with the receiving mechanism removed.
The frame A receives the electro-magnets b b, and the vertical shaft 0, and armature of the motor, said motor being provided with the flywheel d, go vern or-balls e, and circuit-breakersfi This magnetic motor maybe constructed substantially the. same as in Letters Patent No. 96,332; and I remark that a switch may be employed to make or break the electric circuit from a local battery through said magnets, so
'- as to stop or start the instrument.
The barrel 9 is upon the shaft 2, that is driven by a Worm-gear from the shaft 0 and this shaft 2, is sustained bythe frame h it that projects from the frame a: A roller, k, is suspended by slings 3 from h and drawn toward the barrel g by a spring, 4, so as to clamp the strip of paper and cause it to progress with the barrel 9, and this roller k can be swung back and held by a latch, so as-to stop the movement of the paper with out stopping the motor. The trough m is sustained by the frame h, and is in metallic contact with the binding-screw 5 of the line or battery-Wire, and upon this trough is the insulated stud 6 for the arms n of the transinitting disks 1', this stud 6 being connected to the other binding-screw Set the line or battery. This binding-screw 8 is insulated from h. The rounding projections 9 in the bottom of the trough m act with the disk or disks ito close the circuit through the perforations of the paper as the same is drawn along by the barrel g and roller 70. One, two, or more of these disks 7; may be employed according to the number of rows of perforations in the strip of paper, and the insulated springs 10 serve to press the disks down with the necessary force. When the transmitting portion of the instrument is not in use the disk or disks 2' and arms may be held up a pin, 12, inserted into a hole in the side of the trough m,the same being insulated, so as not to close the electric circuit. The detaining-brushs serves to produce a friction upon the paper sufficient to keep it to the surface of the barrel g, and this brush 8 is made to turn upon a stud, 14, and is kept down by a spring, 15. The catch-finger t taking against the arms n lifts them and the disks z, and falling into a notch on the arm n the parts are held back while the paper is bein gintroduced, as seen in Fig. 2. As the brush is turned down this catch-finger is liberated from n and pressed upon the paper by the spring 15. The transmitting-rollers or disks 2 such as 'in my patent No. 96,333, are at the end of springs u, that project from the arm o in the swinging head w, and thishead is hinged at 16 to the insulated block so, that is in metallic contact with 8, bythe bar 17, and the springfork 18 serves to hold the head to when either turned back, as in Fig. 1, or whenturned down, as shown by dotted lines in the same figure. The small screws 19'prevent the springs to being bent by the blow of the rollers 17 in striking the barrel g as the head is thrown over.
I claim as my invention- 1. The swinging-brush s and catch-finger t,
combined with the arm of the transmitting dein connection with a strip of paper havinpe'r- Q forations in two lines, substantiallyas setforth. Signed by me this 6th day of November, A. D. 1871.
GEO. LITTLE.
