. To all whom t may concern.'

Be it known that I, PERCIVAL GREEN, a citizen of the United States, residing at San Francisco, in the county of San'Francisco and State of California, have invented certain new and useful Improvements in Meat- Blocl-Surfacing Machines, of whichthe following is a specification.

This invention relates to surfacing machines and, more particularly, to apparatus for cutting the top of a butchers meat block to a plane surface when the same becomes uneven or rough through use.

The object of the present invention is to provide elicient devices of this character which will be convenient to operate andymay be readily applied t0 or detached from a meat block.

The invention consists in the novel construction, adaptation and combination of devices as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 i is a plan view showing a meat block with my invention applied thereto. Fig. 2 is a side elevation of the same. Fig. 3 is a dew tail vertical section through 3-3 of Fig. 1, and Fig. 4 is a horizontal sectional View through a cable winding barrel and its spindle to illustrate the manner of securing the barrel to the latter and for taking up slack from the cable.

In said drawings, the reference numeral 5 designates a butchers meat block, the top g1 o-f which is to be dressed to anplane surace.

According to my invention I provide a box-like frame 6 which may be constructed of cast iron and is provided upon its front wall 61 with a plurality of conical protuberances 7 which serve to penetrate into a side of the block to prevent the frame tilting in a lateral direction when it is firmly clamped against the block. The clamping of said frame to the block is attained by means of a cable S which embraces the block by a loop, as indicated in Figs. 1 and 2, and has its ends respectively engaged with and then Wound about barrels 9 and 91 which are mounted upon upright spindles 10 and 101 which are j ournaled in the frame 6 in proximity to the corners remote from the wall 61 which is juxtaposed with the block. These spindles are provided with polygonal `upper ends 101 toenable them to be engaged by a wrench or a handle provided with a suitable socket. Intermediate the lengths of said spindles they are each provided with a hole 103 (Fig. 1) extending diametricall-y therethrough and a similarly arranged hole 92 is provided in each of the barrels.`

When the frame is to be attached to a Vblock it is heldrk against the latter, and the f cable looped about the block and the cable ends threaded through the holes of the respective barrels and spindles. The ends are then furtherpdrawn by the operator through the said holes until' the slack is removed from the cable loop and the frame is thereupon rigidly clamped to block by successively turning the spindles through the medium of the referred to wrench or handle.

In such operation it is evident that the cable by passing through the barrels and the spindles, will couple them together and by such .coupling meansthe size of the loop in the cable may be readily varied to accommodate blocks of diiferent diameters and shapes.

11 represent ratchet wheels secured to the spindles and are engaged by pawls 12 which are pivotally connected to said frame to pre` vent any accidental unwinding of the cable from the barrels. Extending longitudinally through the frame is a screw 13 which engages in a nut 11 (Fig. 3) havinga socket 141 in its top to serve as a seat for the spherical lower end 151 of a cylindrical-post 15. This post extends through an aperture 16 in a nut 161 which engages the threads of a screw 17 extending transversely through the frame. Said screws are provided with polygonal ends 131 and 171 whereby they may be rotated by a wrench and are secured against axial 'movements by set collars 132 and 172. By suitably regulating the nuts 11 'and 16 throughthe instrumentality of the respective screws, the post 15 may be adjusted to be in a vertical position or in a position rectangular to the plane to which it is desired to dress the top of the meat block, even though the frame itself may be considerably tilted from the horizontal. The post 15 serves as a pintle for a substantially horizontal arm comprising two members 18 and 181 which are jointed or connected together by a hinge pin 19.

At the free end of the outer arm member 181 are provided bearings for an upright arbor having v*mounted atdit's lovver end a circular saw 21. Said arbor is driven by an electric motor of ordinary or suitable "structure which is inclosed in a casing l22 regulated, the operator completes the 'electric circuit to I'rotate the saw which then controlled by the v:operator lto cause it to traverse the'top of the block by swinging the saine about the axes of "the post A and theelboiv joint of the arm. The saw is most conveniently movable through the agency of 'the 'handle bar 24.

1. *Af block dressing device of the characte'r described, comprising a frame, Ine'ans for fdetaclhably securing said fra-me to a block, 'fa post, means provided in said frame for regulatingthe angular position of said post with respect to the traine, a jointed arm supported by y'Sd Post an arbor ucar' i ried by the outer vend oit said arm, a saw `mounted on 'said arbor, 'and a rr'iotor for rotating the saw through the medium of said ar or.

2. In a block dressing machine, the combination With an upright arbor, a saW mount- -ed thereon, means to drive said arbor and the saw, an arm carrying said arbor and the driving means, and a post supporting said arm, of a frame, a step-bearing provided in the frame Jfor the post, la post journal bearing provided in the frame above said step-bearing, means for adjustably moving Ysaid journal and step-bearing in 'rectangular relations to each other, yand means to detachably secure said frame to a block vvhich is to 'be dressed.

3. In apparatus of the class described, the combination with an upright post, 'a saw, driving means for the saw, and operative connections between said post and the saw to enable the latter to be swung in a horizontal plane, 'a frame, means provided in said frame for supporting the post in various adjusted positions,'and means for clampingsaid frame fto the block to be dressed.

Signed at San Francisco, Calif., this 1st day of September, 191'5.
