WEDGE-CUTTING MACHINE.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed February 1,1906. Serial ma mas.

1'0 all whom, it may concern.-

Be it known that I, SAMUEL BOZEN, residing at Sterling, in the county of VVhiteside and State of Illinois, have invented certain new and useful Improvements in I/Vedge-Cutting Machines; and I do declare the following to be a full, clear, and exact description of the inventlon, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to machines for cut ting wedges from blocks of wood, and is not only novel but is quite simple and can be manufactured with little expense.

Then carriages and similar vehicles have been used for a time, the spokes in the wheels frequently become loose in the felly and it becomes necessary to tighten them by forcing small wedges into the outer ends of the spokes. These wedges are generally constructed of wood and are usually formed with a draw-shave on the end of a piece of wood of suitable size, the completed wedge being then sawed from the stick. My device is designed to manufacture such wedges with considerable rapidity and little labor, dispensing with the laborious operation just mentioned.

In the drawings, Figure 1 is a side elevation of my device, partly in section. Fig. 2 is a front elevation thereof with the operatinglever removed. Fig. 3 is an enlarged detail showing the manner of operation of the device.

Similar numbers refer to similar parts throughout the several figures.

1 represents a perpendicular block provided at its lower end with a shank 2, by means of which such block can be suitably attached to a bench or held at a desired height in a vise. On the front face of the block 1 are fixed a pair of guides 3 3, between which and the block 1 a knife 4 has vertical movement. The knife 4 is provided with a shank 5 integral therewith, the upper end of such shank being pivoted to a hand-lever 6, fulbeyond the wall of the recess 8.

crumed on a bracket 7, fixed to the upper end of the block 1.

In the front face of the block 1 is a wedgeshaped recess 8, and in the rear wall of such recess is an annular recess 9, holding a coiled spring 10, one end of which normally projects Projecting from the frontface of the block 1, just below the recess 8, I provide a support 11, preferably integral with block 1.

The lower edge of the knife 4 is beveled on the outer face-that is to say, the face away from the block 1so that in the operation thereof the cutting edge of the knife passes along the face of such block.

To operate the device, the lever 6 is raised until the blade of the knife clears the recess 8 and a block 12 of wood inserted into the re cess, as shown in Fig. 3, the thickness of the block 12 being such as to permit the passage thereof between the guides 3. The knife 4 is then forced downwardly, cutting a wedge-shaped piece 13 from the end of the block 12. The grain of the wood in the block 12 is transversely of the block, as indicated by the small arrow above the same, the cutting of the wedge being thereby rendered more easy. In the downward movement of the knife 4 the force of the operation tends to break a wedge-shaped piece 14 from the end of the block 12, leaving the end of such block square and ready for the formation of the next succeeding wedge.

I/Vhen the knife 4 is raised after the wedge has been cut from the block of wood, such wedge is expelled from the recess 8 by the spring 10.

I do not wish to be understood as limiting myself to the manufacture of wedges of the class herein mentioned, as wedges of varying sizes and shapes and which can be used in various places aside from the one referred to are capable of being formed by mechanism similar to that shown and described herein.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

In a device of the class described, the combination of an upright block fashioned into a upon the block under the recess, and a spring 10 seated in said depression in the bottom of the recess.

In testimony whereof I aflix my signature in presence of tWo Witnesses.
