10 all whom it may concern:

Be it known that I, GEORGE W. SIMMONS, a citizen of -the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Cyclometer Attachments for Type-Writing Machines, of

which the following is a specification.

This invention relates to improvements in a cyclometer attachment for t pe-writing machines; and it" consists of t e novel arrangement, construction, and combination of parts, as will be fully hereinafter described and claimed.

The object of my invention is to provide an ordinary type-writing machine with a cyclometer for registering the number of times the carriage has been operated daily.

A further object of my invention is to keep record of work done by the stenographer.

Figure l is a perspective View of my invention shown in position and in connection with the escapement of a type-writing machine. Fig. 2 is a top plan view of the same.

Referring to the drawings in detail, 3 indicates the frame of a type-writing machine, and 4 the rack which meshes with pinion 4.

5 indicates a cyclometer of ordinary and common construction which is attached to the frame 3 oi the type-writing machine bymeans of the bracket 6. The mechanism of the cyclometer is controlled by the shaft 7, upon which is mounted a ratchet-wheel 8 and a gear-wheel 9. To tl1e'gear-wheel 9 is pivotally connected a pawl 10, its tooth contacting with the teeth of the ratchet 8' and held in position by the spring 11 The ratchet-wheel 8 is rigidly connected to the shaft- 7, while the gear-wheel 9 is loosely mounted thereon and meshing with the gear wheel 12, rigidly mounted upon the escapement-shaft 13 of the typ wliter, heo )eration of my invention is follows: While the type-writer is being operated the escapement, during the manipulation of each key, has a step-by-step motion, which will o'perate the gear-wheel 12, which in turn operates the gear-wheel 9, and during this operation the pawl 10, moving with the gearwheel 9 in. the direction indicated by the arrow, allowing said pawl to slide over the ratchet-teeth without affecting or operating the cyclometer mechanism. When the carria e has reached its destination, the operator, rep acing the carriage to the starting-point, Wlll cause the gear-wheel l2 and 1?. to move in o posite directions, thereby allowing the pawl 10 to enga c with the ratchet-wheel 8 and revolve the si aft, which in turn operates the cyclometer mechanism, ad vancing it one number.-

I have shown my attachment as applied to a Remington t pe-writer of modern. style and construction; lint it is obvious that the device may be attached to dilierent styles and. constructions of type-writing machines.

I do not desire to limit myself to this precise method of attaching the cyclometer to the type-writing machine, it will he nec essary in applying the cyclometer to different makes of typewriters to add an additional gear-wheel. and a diil'erently construc ted support, whereby the cyclometer is attached to the machine.

Having fully described my invention, what I desire to claim and. secure by Letters hat-- ent is 1. A cy'elometer attachment for type a rite ing machines comprising a cyclometer; a bracket supporting the same on the frame of the type-writer; a shaft communicating with and operating the cyelometer mechanism an escapement mechanism of a type-writer, and means between the escapement mechanism and the cyclometer-shaft for operating the cyclometr, substantially as set forth.

2. In a cyclometer attachment for type writers, the combination of a cyclometer provided with a shaft arranged to be operated thereby, a gear-wheel loosely mounted thereon, the-escapement mechanism of the typewriter provided with a shaft and gear-wheel arranged to mesh with the loosely-mounted gear-wheel, and pawl-and-ratchet means between the loosel-mounted gear-wheel and the cyclometer-s iait, whereby the latter is operated when the escapement mechanism moves in one direction, but remains at rest when moved in the other direction.

3. A cyclometer attachment for type-writ mg machines comprising a cyclometer su1tably supported to the frame of the type writer; ashaft communicating with the mica 'nal mechanism of the cyclometer; a ratchetwheel rigidly mounted upon said shaft; a

gear-wheel looseiy mounted'upon said shaft In testimony whereof I have signed my an escapement mechanism of'a type-writer, name to this specification in presence of two 10 a shaft opgrgted lay the esoa enllent melglansubscribing witnesses.
