IMPROVEMENT IN MACHINES FOR CUTTING WEDGES.

Specification forming part of Letters Patent No. 121,264, dated November 28, 1871.

To all whom it may concern:

Be it known that I, NORMAN WARNER, of Jasper county, State of Indiana, have invented certain Improvements in Machine for Cutting Wedges, of which the following is a speciiication:

riveted to the sides of the box B so as to form slides. E E are slides that work between the lugs D D. F is a plate of iron that rests upon the slides E E, and is adjusted by means of the thumb-screws V'V and the slides E E. G G are the slides for the chisel J I. H is the groove in the slides G G. I is the chisel. J is the sharp K is a rack that is riveted to the chisel. L is the lever-pinion that works in the rack K. M M are the bearings and braces for the lever-pinion L. N is the pin or bolt-hole in the lever-pinion L. O is a hollow shank for the handle P to fit in. l? is the handle of the lever-pinion L. Q is a block of hard wood inserted between the slides G G and bolted through the bed-timber A. This is placed here to let the chisel strike against, and also for a stop for the wood that is to be formed into a wedge.

R is a piece of wood in position to be made into a wedge. S is a dotted line, showing the path that the chisel travels. T represents the wedge that will be formed under the dotted line S after the chisel J I has been forced through the piece of wood. U U are the thumb-nuts made fast to the bottom of the iron box B and directly under the slides E E. VV are thumb-screws to adjust the plate F. W is the bolt that the stop-block Q is made fast to the bed-plate with. X X X are bolts that secure the slides G G to the boxB and the wooden bed A.

The operation of my improvement is as follows: rlhe handle P of the lever L is thrown forward, as in Fig. l., and the block R is placed between the slides G G upon the plate F, and the lever is then carried back, thus forcing the chiselV J I, by means of the pinion L and rack K, forward, and the wood is shoved Off Of the upper side of the wedge. By moving the slides E E up or down by means of the thumb-screws V V a wedge of any desired taper can be made.

I claim- A wedge-cutting machine, composed of the several parts herein shown and described, constructed and arranged as and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

NORMAN WARNER.
