SPECIFICATION forming part of Letters Patent No. 326,643,6ated September 22, 1885. Application filed October-16, 1884. (No model.)

To all whom, it may concern.-

Be it known that I, VVILLIAM S. HALSEY, of Oakland, county of Alameda, and State of California, have invented an Improvement in Mowers; and I hereby declare the fOllOwing to be a full, clear, and exact description thereof.

My invention relates to that class of agricultural implements known as mowers, in which the sickle or knife is driven by power derived from the wheels and transmitted through suitable shafts and gears; and my invention consists in a sleeve loosely mounted on the counter-shaft which carries the bevel gear, said sleeve having at one end a collar against which the hub of said gear bears, and at its other end a set-screw which is seated in the yoke mounted on the counter-shaft, and which carries the shaft which bears the pinion engaging with the gear, as I shall hereinafter fully explain.

The object of my invention will be set forth how strong the thrust may be, it but throws in the course of the following description.

Referring to the accompanying drawings, Figure 1 is a rear elevation of a mowing-matchine, showing my invention, the side frame of the machine carrying the sickle mechanism being omitted. Fig. 2 is a plan showing the counter-shaft, shaft D, gear, pinion, and yoke, and the application thereto of my invention. Fig. 3 is a longitudinal section of the sleeve F. A are the wheels, from one of which,in the usual manner, by means of the internal gear and a pinion, power is transmitted to drive the counter-shaft B, mounted in hangers a at the rear of the machine. 0 is the usual yoke, through the arms of which the shaft B passes. This yoke carries the shaft D, Fig. 2, which extends forward to drive the sickle. Upon shaft B is a bevel-gear, b, which meshes with a bevelpinion, d, on shaft D. E is the clutch by which the gear I) is thrown into or out of connection with shaft B. These parts are arranged and operate in a well-known manner, and constitute sufficient of the machine to show the application of my invention.

Heretofore it has been difficult to keep the gear b and pinion d in constant and perfect engagement, as the thrust on the counter-shaft has a tendency to move the gear I) back from the pinion. It has been attempted to obviate this difficulty by means of collars on the shaft bearing against the hangers; but these means have proven unsatisfactory and do not effect a perfect result. It is the object of my invention to hold the gear and pinion in constant engagement.

Upon shaft B is loosely mounted a sleeve,F, one end of which is enlarged to, or is provided with, a collar, f, as shown in Fig. 3, against which the hub b of gear I) bears. The other end of the sleeve has a lug or car, G, through which a set-screw, g, passes, and is seated in one arm of the yoke C. It will thus be seen that when the thrust on shaft B tends to carry the gear away from the pinion, the hub of the gear bearing against the eollarfon the sleeve transfers the effect of thethrust through said sleeve and its screw to the yoke, and as this yoke carries the shaft D which bears the pinion d, it is obvious that said pinion is thrust over also, and its engagement with the gear I) is continued. Therefore, no matter both gear and pinion in the same direction and to the same distance, whereby their engagement is not broken.

The sleeve F being loose upon the drivingshaft does not interfere with its operation,but on the contrary protects it from the grass,&c., which, when the shaft is exposed, clings to and winds around it.

The sleeve being stationary does not so collect the grass, weeds, &c. As the sleeve is fixed and the gear Z) rotates, there will be wear upon the collar f on the end of the sleeve. This wear can readily be taken up by adj usting the set-screw 9.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a mowingmachine having a countershaft, B, with gear I), a shaft, D, with pinion d, and a yoke,O, mounted on the counter-shaft and carrying shaft D, the loose sleeve F on 5 the counter-shaft, against which the hub of gear I) bears, and a connection between said sleeve and the yoke, whereby the thrust on gear I) is transferred through sleeve F to the yoke to maintain the engagement of pinion d with said gear, substantially as herein described,

2. In a mowing-machine having a counterand carrying shaft D, the loose sleeve F on the shaft, B, with gear I), a shaft, D,with pinion d, counter-shaft having a oollar,f, on one end and a yoke, G, mounted on the counter-shaft against which the hub of the gear 12 bears, and I 5 and carrying shaft D, the loose sleeve F on a set-screw. g, at its other end seated in the 5 the counter-shaft connected with the yoke at yoke G, substantially as and for the purpose one end and having a collar, f, on the other herein described.
