Patented July 29, i213.

Original application filed. August 17, 1910, Serial No. 577,684. Divided and this application filed March 15, 1911, Serial No. 614,638. Renewed December 26, 1912. Serial Ito. 788,755.

To all whom it may concern Be it known that I, GEORGE H. GoA'rns, a citizen of the United States, residing at Worcester, in the county of "Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Gearing, of which the following is a specification, forming a division of my application for a clipping-machine, filed on or about August 17, 1910, Serial No. 577,684, accom anied by drawings forming a part of the same. a

My invention relates to a mechanism adapted to be used in connection with power operated clipping machines and combining therewith a disk wheel serving as a fly wheel and also adapted to receive abrasive material upon its exposed side, or its face, for grinding or polishing and driven by means of power applied by the operator through the inst-rumentality of a crank or other mode of application. The fly wheel is provided with an inclosing framework which may be utilized as a rest for the articles to be ground, or polished.

'The object of my improvement is to simplify and render more efficient the operative parts of the machine. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the complete apparatus. Fig. 2 is a plan view of the grinding wheel and the means for applying power thereto. I Fig. 3 is a vertical sectional view on the broken line 3-3, Fi 2.

imilar reference characters refer to similar parts in the different figures.

In clipping machines of the class referred to, power is applied by a rotary motion which is conveyed to the clipper head through the medium of a' flexible shaft and is there converted into a reciprocating motion of the movable cutting plate.

My present invention relates to a mechanism by which the rotary motion is conveyed by the operator to the clipping machine, ad comprises a fly wheel which may also be utilized for the purpose of grinding the cutting plates of the clipping machine or other articles.

In the accompanying drawings 1 denotes an upright stand supported upon a tripod 2, and mounted upon the upper end of the stand 1 is a frame 3 which supports the gearing in the present instance consisting of,

a gear wheel 7 carried upon the shaft 4 and connected with a pinion 8 upon the shaft 6 by means of an intermediate pinion 9 and integral gear 10 turning loosely upon a stud 11. Attached to the shaft 6 is a fly wheel 12, and upon the outer end of the shaft 6 is a pinion 13 adapted to engage a similar pinion 14 carried upon a spindle 15, which is journaled in an arm 16 having a hub 17 which is pivoted concentrically with the shaft 6 to provide for a free swinging movement of the arm 16 about the. axis of the shaft 6. 1 a:

The framework in which the rotative mechanism just described is mounted consists of a screw threaded socket 18 to receive the upper end of the upright stand 1, and above the socket 18 is a cylindrical case 19 which incloses the gear chamber 20. The gear chamber 20 is closed by a cap 21 having a hub 22 in which the shaft 4 is journaled. At the lower end of the framework an arm 23 projects transversely to the fly wheel 12 and is bent upwardly at 24, having a bearing 25 at its upper end for the shaft 6. Extending laterally from the upper end of the arm 24 are horizontal bars 26, 26, which are extended around the periphery of the fly wheel 12 and are joined to the cylindrical casing 19 forming an inclosing framework for the fly wheel 12, and also providing suitable support for the shaft 6, which is journaled in the bearing 25 upon one side of the fly wheel in a similar bearing 27 formed in the side of the casing 19.

If desired, the inclosing frame of the fly wheel 12 may be provided at one end with a handle 28 by which the structure may be steadied by one hand of the operator while the other is applied to the crank handle 29. A rotary motion of the spindle 15 is communicated through a flexible shaft 30 of any known construction to a driving spindle 31 journaled in a frame 32 of the clipper head ployed the inclosing framework 26 may be utilized as a rest for the articles to be ground.

I claim 7 Lln a machine of the class described, a

, framework comprising a socket for a supporting stand, a casing inclosing a gear chamber, an arm extending horizontally from the bottom of said frame and upwardly and. supporting at its upper end a bearing for a rotatable shaft, a rotatable jour- ,naled at one end in said bearing and at its oppos te endin one of the side walls of said 'gear'ehamber', and a fly wheel carried by said shafh'a nd held in the space between the gear casinga'nd the upward extension of said arm. 4 111 a machine of the class described, a casing'inclosing a gear chamber, a framework consisting of a vertical arm connected with the lower part of said casing, horizontal arms connecting said casing with the upper end of saidvertical arm, a rotatable shaft j ournaled at one end in said vertical arm and at its opposite end in the side wall of the caslng, and a fly wheel held on said shaft with its upper portion extending above said horizontal arms.

3. In a machine of the class described, a gear casing, a framework consisting of hori zontal arms and a vertical arm connected with said gear casing, a rotatable shaft journaled at one end'in a side wall of the gear casing and at its 0 posite end in a bearing at the junction of sald vertical arm with said horizontal'arms, a hub on said framework concentric with said shaft, an arm journaled on said hub provided with a hearing at right angles with said shaft, a spindle journaled in said bearing, and a geared connection between said spindle and said shaft.

4. In a machine of the class described, a casing inclosing a gear chamber, a framework comprising a journal bearing, arms connected with said casing and supporting said journal. bearing, a shaft having one end journaled in said bearing and its opposite end journaled in said casing, and a fly wheel supported on said shaft between its hearings.v

Dated this thirteenth day of March 1911.
