FRANKLIN HOLLAND, OF GRAND RAPIDS, MICHIGAN.

GAMING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 329,-6I7, dated November 3, 1885.

Application filed October 21, 1884.

T 0 all whom, it may concern.:

Beit known that I, FRANKLIN HOLLAND, ofjGrand Rapids, in the county of Kent, and in the State of Michigan, have invented certain new and useful Improvements in Carving-Ma chines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to improvements in carving or ornamenting machines, and will be fully described hereinafter.

In the drawings, Figure l is a side elevation ofa carving-machine embodying my invention. Fig. 2 is a vertical section through the center of the machine; and Fig. 3 is a sectional top plan View on line x x of Fig. 2.

A A indicate the frame of my device, the horizontal arm A ofwhich has in the under side face of its outer end an annular slot, a ,wherein is loosely fitted the annular flange b b, formed in the upper face ofthe yoke B. This yoke is thus adapted to be freely swung in the supporting-frame, and is, moreover', held thereon in any adjustment desired by means of any suitable clamping device, as shown at b b', between the outer wall and inner circular wall, a, of A. The yoke carries in its under side the bearing-boxes B B2, the upper halves of which are made integral with or fastened to the said yoke, while the caps b2 b3 are fastened to the boxes in the usual manner. rllhe rear cap, b2, is provided with a step, b", having ascrew-threaded perforation, wherein works the step-screw b5, designed to firmly hold in position against the box B2 the spindle C. This latter is provided between the bearing-boxes B and B2, in which it is journaled, with a flanged pulley, C', and this is connected with any driving mechanism through the belt D,which passes upward into the circular opening made at A2 in the rounded outer end of the arm A. rIhe spindle C is lengthened by Serial No. 146,090. (No model.)

means of the center c, to the outerend of which may be iitted any one of the multiform cutters generally in use. as shown at c.

It will be readily understood `that by the arrangement described above the operator of the machine will be enabled to swing the spindle O in any direction in the plane in which the yoke B is hung in the frame, and to hold the said spindle in the adjustment desired as long as is needed.

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

l. In a carving or ornamenting machine, the combination of a horizontal supportingarm having an annular groove in its under side, a yoke provided with an annular lange working in the arm-groove, and with vertical adjusting clamp-bolts to hold the said yoke in any desired adj nstment, and a spindle adapted to be rotated in box-bearings of the yoke, snbstantially as and `for the purpose set forth.

2. In a carving or ornanicnting machine, the combination ofthe frame A, having horizontal supporting-arm A', with annular slot c c on the under side, and central circular opening, A2, the swinging yoke B, having annular flange b b, adjusting clamp-bolts b b', and bearing-boxes B B2, with caps b b3, and step b* and step-screw b5, for adjusting the spindle, and the spindle O, carrying the pulley C and its center c, with cutter c, substantially as shown and described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Grand Rapids, in the county of Kent and State of Michigan, in the presence of two witnesses.

FRANKLIN HOLLAND.
