ROTARY WOOD-SPLITTING- MACHINE.

Specification of Letters Patent No. 13,492, dated August 28, 1855.

To all whom it may concern Be it known that I, Gr. WV. 13. GEDNEY, of the cit-y, county, and State of New York, have invented certain new and useful Improvements in Splitting Wood, Consisting of Machinery Therefor; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing, in which Figure 1 is a side elevation; Fig. 2, a knife detached; Fig. 8, a vertical transverse section; Fig. 4, a. top plan; Fig. 5, views of a straight knife.

My improved machinery for splitting fire wood consists of a large cylinder or rim a that is attached by one edge to a wheel or disk I) on an axle c that is supported in an upright frame (Z so as to be easily revolved. In the rim a above named are two. or more oblong openings into which the splitting wedges or knives e are inserted. A detailed view of one of these knives is seen at Fig. 2. It consists of a base that fits the curve of the inside of the rim. The rear part or back at e is grooved so as to embrace the rear edge of the opening, and the front portion or flank 6 laps over the front edge of the opening of the rim on the inside and is there confined by a single bolt, as clearly represented. The edge of the knife or wedge 6 projects a proper distance above the outer perimeter of the rim to make the proper cut. The most effective form of knife is made with V shaped corrugations, the apex of the V that projects most being divided for a purpose to be decribed. Two of these knives may be placed one on each side of rim, the projections of one knife being opposite the depressions of the other, or one of the knives may present a straight edge and the other the corrugated as before stated.

Above the splitting wheel just described there is a hopper f, into which the wood after it has been sawed is put and falls by its own gravity upon the revolving wheel where it is split as the knives come around just in front of the hopper there is a set of thin projecting plates that project down one opposite each depression in the knife edges and others opposite the openings at the apex of the knives before named. These serve to clear the knives and allow them to work freely. At the rear side of the trough I have a series of small fingers or catches h on an axis that is attached to a long lever 2' so as to be turned by it. These catches come in contact with the wood to be split at the point where the knife enters and prevent its rising while under the action of the knife or splitting wedge. lVhen this passes the wood is relieved so as to fall by means of the action of a pin upon the lever i. The large wheel may be geared in any convenient form with the driving power. In this drawing I have shown a spur gear around the rim a of the large cutter into which a pinion m Works and on the axis of the pinion there is a band wheel a to connect with the driving power.

Having thus described my invention what I claim therein as new and for which I desire to secure Letters Patent is- 1. The machine herein described for split ting wood consisting of the V grooved knives acting upon the wood as herein described having openings in their apex to receive the clearers as above specified and in combination therewith the fingers for holding down the rear end of the wood to be split.

2. I also claim the mode of attaching the knives by the groove 6 at their back and an overreaching flanch e by which the resisting strain tends to hold the knife in place as herein specified without bringing the strain upon the bolt by which it is fastened.

In witness whereof I have hereunto set my hand this twenty ninth day of June G. W. B. GEDNEY. Witnesses:

JAcoB HATZEL, J r., J. C. GREENOUGH.
