RUFUS ANDERSON, OF PEEKSKI LL, NEW YORK.

AUTOMATIC TELEGRAPH.

SPECIFICATION forming part of Letters Patent No. 289,205, dated November 27, 1883.

Application filed March 17, 1883. (No model.)

To (LZZ whom, it may concern.-

Be it known that I, Bonus ANDERSON, a citizen of the United States, residing at Peekskill, in the county of Westchester and State structed according to my invention.

of New York, have invented new and useful Improvements in Recording-Instruments for Chemical Telegraphs, of which the following is a specification. p This invention relates to improvements in recording-inachinesused in chemical telegraphy, its objects being to facilitate the placing of the record-fillet upon the contact-wheel under the stylus, and to enable the stylus to be kept sharp and clean without removing itfroin the apparatus.

In the accompanying drawings, Figurel is a side elevation of a recording-machine con- Fig. 2 is an end view of the same. Fig. 3 is a side elevation, showing the contact-wheel lowered away from the stylus; and Fig. 4 is an end view, partly in section.

The letter a indicates the main vertical supporting-plate; a, the base-plate, and a the ac]; standard supporting one of the journals Tof the driving-shaft b, which is indicated in dotted lines, and has mounted upon it the driving-pulley 0 and the gear-wheel d, which is shown in dotted lines, Figs. 1 and 3, but not visiblein Fig. 2. Upon the shaft 1) is pivoted a lever, e, carrying at its innerend a transverse sleeve, f, in which is arranged a short shaft, having its ends projecting fromsaid sleeve, its rear end having fixed upon it a gear-wheel, 71, and its front end projecting through a curved slot, 1', in the vertical plate a, and having fixed upon it the contact-wheel It, over which passes the record-fillet Z from a suitable reel-such, for instance, as shown at in. The gear-wheel h meshes with the gearwheel (Z, mounted on the shaft b, and receives motion from said gear-wheel when the shaft Z) is rotated by means of a cord or belt applied, in the usual manner, to the driving-pulley c. The letter it indicates the stylus, which is constructed in the usual manner, and adjustably mounted in a bracket, 0, secured to the top of the plate a. The normal positionof the contact-wheel k is as shown in Fig. 1, the outer end of the lever a being depressed and engaged by spring-latch p to hold said contact-wheel in this position. When the contact-wheel is in j u'sted to bear with proper force upon the fillet as it passesbver the contact-wheel. It willbe observed that when the lever e is moved the gear-wheel h has a planetary movement about the wheel d, said movement being limitedby the length of the slot z, through which the shaft of said wheel extends, and therefore when the contact-wheel, which is also mounted upon said shaft, is lowered, as shown in Fig. 3, the rotation of said contact-wheel will continue as long as the driving-shaft is kept in rotation. The main purpose of lowering the contact-wheel is to enable the record'fillet tobe passed thereover without disturbing the stylus, and when said fillet has been properly placed the contact-wheel may be raised and the lever latched to maintain the wheel in position and the fillet in contact with the stylus. There is, however, a further purpose in lowering the contact-wheel It, which is to permit the sharpening-wheel to be brought under the stylus and in position to be operated by the rotation of the contact-wheel.

The letter I. designates the sharp eningwheel, which is mounted loosely on the end of a stem, a, which rotates in a sleeve-bearing, 11, projecting from the back of the plate a, and said stem is provided with a head, a, between which and the plate a is arranged a spring, a", which forces the stem rearwardly and holds the sharpening-wheel i normally in a recess formed to receive it in the plate a, (shownin Fig. 4,) so that it will not interfere with the contact-wheel. To the rear surface of the sharpening-wheel is secured a leather disk, 10, having a slightly greater diameter than the sharpening-wheel, and when the contact-wheel is lowered and the stem at pressed forward, as indicated in dotted lines, Fig. l, the periphery of the leather disk w comes in contact with theperiphery of the contact-wheelie, and by such contact receives rotary motion from said contact-wheel, which is then in contact with the point of the stylus, and grinds said point to proper shape and gives it a clean, bright surface, so that it will operate properly in communicating the electric current to the contact while through the record-fillet.

As the wheel t is in use but a few moments at any one time, it may be held in proper position in relation to the stylus and contactwheel by manual pressure upon the buttonhead a; or, if desired, a bayonet or other latch or catch may be formed in the end of the sleeve 0 and stem at, by which it may be locked in proper position for operation so long as desired.

It has heretofore been necessary to remove or turn up the stylus and sharpen it by means of a file, which is inconvenient and entails loss of time, both in sharpening and readjustingthe stylus.

Having now described my invention and explained the operation thereof, I wish it to be understood that I do not limit myself to the precise details of construction illustrated in my drawings, but may vary the same in any manner for the better carrying out of my invention without departing from the essential principles thereof.

What I claim is- 1. In a telegraph recording-machine, the combination of the fillet carrying contactwheel, mechanism for raising and lowering the same with relation to the stylus, and means for rotating the same irrespective of its raising and lowering, substantially as described.

2. The combination, with the fillet-carrying contact-wheel and means for rotating the same, 3 5 of mechanism for raising and lowering said wheel or moving it diametrically and maintaining its rotation at the same time, substan tially as described.

3. The combination, with the stylus, the filo let-carrying contact-wheel, and mechanism for raising and lowering the same and maintaining its rotation, of a sharpening-wheel-arranged to be brought under the stylus and to receive rotary motion from the contact-wheel 5 when the latter is moved away from said stylus, substantially as described, and for the purpose set forth.

4. The combination, with the stylus and contact-wheel and means for moving said contact- 50 wheel to and from the stylus, of a sharpening wheel and means for bringing said sharpening-wheel into rotary contact with the stylus when the contactwheel is moved away from said stylus, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
