T0 WHOM IT MAY CONCERN:

Be it knownthat S. W. PALMER and J. F. PALMER, of Auburn, in the county of Cayuga, and State of New York, have inventedcertain new and useful Improvements in Gearing; and the following is hereby declared to be a. full, clear, and exact description of the same, reference being had to the accompanying drawings, in.A which-- p Figure 1 is n. section ofthe gearing on the line :t x, iig. 2.

Figure`2 is a section'of the same on the line y y, iig. l.

This invention relates to the gearing. of planing-machines, clothes-wringers, and other like machines, in which the shafts or rolls arercquired to operate at varying distances from each other, andare liable to have a. lateral play or a'slipping movement in the direction of their length. n

The object of this invention is to so combine and arrange the gearing as to prevent the lateral play of the shafts `or rolls, which is more especially to be guarded againstin elothes-wringers and likennachines, where such lateral or slipping action of the rolls is apt to damage and sometimes tear the clothes.

To this end the invention consists in the combination of toothed or cogged wheels, when used in pairs upon the same shaft, with a plate or plates, arranged upon theexterior opposite or interior opposite faces of either pair, in the manner hereinafter described, whereby the wheels on the one shaft shall be heldin place by the plates or disks of the, wheels on the other shaft, and thus prevent the latera'l'play of thc one shaft with respect to the other. i

To enable others skilled in the art to understand and use this invention, the manner in which the same is or may be carried into elfect will now be described, by reference to the accompanying drawings.

A and -B represent the frame that supports the'bearings in which the shafts C and D revolve. The shafts carry gear-wheels composed of circular plates or disks, elflj, upon the face or faces of which are formed cogs or teeth e j", so as to project therefrom. The teeth upon any one of the plates, for instance, j, areearranged at equal intervals apart, and equidistant from a common centre or axis. As regards the shape ofthe teeth,A

that represented in lig. 1 is suggested as a good one, although other forms will answer the purpose. Theyare supported by the pla-te or disk with which they are united, and do not therefore depend for support upon` their. connei im with the hub of the wheel, as is usually. the case; and'for this reason they may be lof much greater' length l'han ordinary cogs,`thus increasing vthe range in which the shafts can lmove towards or away from each other.

Thegearlng represented in the drawings illustrates the manner in which a pair of gear-wheels thus formed may be united for operation upon each shaft, and upon one side of ainachine, as, for instance, a clothes-wringen The shaft C is located in the vstationary portion of the frame, while the shaft D is mounted in-.the usual sliding box, which is capable of moving toward or away from the lower part of the frame, so as to vary the distance between the shafts. The wheelsffs are'mounted upon the ends of a hub,`F, in such manner as to present to each otherl their cogged faces, while a corresponding hub, E, upon the shaft C, carries' a single wheel or plate, upon enen faceof which are formed cogs or teeth e2. The plate e1 is so placed`upon the shaft C that it shall penetrate or be received within the interval between the two wheels on the other shaft, and its teeth, which gear with the teethf2 of the respective wheels on the` other shaft, are encased or held between the plates or disks-J' f. By this means thewheels which compose the gearing are held in their proper relations, and all lateral or end-play of the-shafts with respect to each other is prevented.

It will be seen also that the plates or disks on each of the shafts. extend somewhat beyond the teeth formed upon` them, and bear such relation to the hub on the other, that when the teeth ef2 have meshed to a certainv depth, the periphery of such plates will bear upon the opposite hub, and thus prevent the clogging or jamming of' the teeth, which would occur, without such precautionary measure, when the wheels were brought in close connection.

In machines such as described, it is often desirable to mount the gears which compose eachpair upon the opposite ends of the same shaft, instead of upon the some enti, :te represented in the drawing. For instance, the wlleelsf3 an@ el may he mounte upon their respective shafts! D C, on one sieof the machine. While the wheeif, and one Similar to `e", 'muy occupy the Sonie relative position upon the other ends of their shafts. in such case it will, of course, he necessary for eneh of the Wheels e1 to carry no more than one set of teeth. The

V:irrengement and position of the wheels upon the shafts with relation to euch other will, however, 'remain substa'ntinliy unohangeci, no matter what distance may intervene between the Wheels of the same pair, so than the wheel or plate js will be Contiguous to the exterior foce of the eos'e2 on one `side, und thewheel'or plntej'1 on the other side of the nin-chine will occupy the some position with relation to the cog a2 with which it gears. 'n like manner, the plates el on euch side will be contiguous to the interior opposite faces of the cngsfz, so that the lateral ploy er slipping movement of one roll upon the other will he ns eeetunlly prevented as beforeh v Having non' described this invention, what is claimed7 :mil desired to lie secured-hy Letters Potent, is es follows:

The Combination ot toothed or cogged wheels, when nsedin pairs upon the saine shaft, with :i plate or plmeearranged upon the interior opposite or exterior opposite faces ol" either pair, in the manner described, whereby the wheels on the one shaft shall he lielil in platee by the plate or plates of the )vlieeisnn the other shaft.y and thus prevent the lateral ploy of the one shaft with respect to the other, :is set forth.

In witness whereof', LDAVID LYMAN, Treasurer of the Metropolitan Washing-Machine Company, noting for anni in 'behalf of said company, have hereunt-oeet my hand before two subscribing witnesses.
