MACHINE FOR SPLITTING WOOD.

Specification of Letters Patent No. 19,867, dated April 6, 18158'.

To all whom it may concern:

Be it known that I, FRANZ NOETTE, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Machine for Splitting Kindling- Wood; and I do hereby declare that the following is a full, clear, andeXact description of the same, reference being had to the annexed drawings, making a part of this specification, in ,which- Figure 1, is a side elevation of my improvement. Fig. 2, is a front view of ditto, a portion being bisected or broken away to show the working parts. Figs. 3 and 4, are detached views of the feed movement. Figs. 5 and 6, are detached views of the cutters.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in the employment or use of an intermittingly rotating table and plunger provided with cutters arranged in a peculiar way the above parts being combined and arranged to operate as hereinafter shown and described, whereby wood that is sawed into proper lengths may be split into lindling wood with the greatest facility. l

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents an upright which is attached to a proper base B, and C, is a vertical shaft the lower end of which is stepped in the base B, the upper end having its bearing in a horizontal arm a, attached to the upright A. To the upper end of the shaft-Qa circular table or bed D, is attached, said table or bed having a rack E, formed on its under side at its periphery.

F, is a vertical shaft which is fitted and allowed to work freely up and down in guides Z2, attached to the upright A. To the lower end of the shaft F, a weight G, is attached, and a shoulder c, is formed on the shaft F, said shoulder being above the lower guide Z9. The shaft F, has an elastic substance cZ,to serve as a buffer placed on it just below the shoulder c, and above the guide b', india rubber or a similar material would answer.

H, H', represents two cams or eccentrics, the journals of which are fitted in proper bearings e, vat the upper part of the upright A. The inner ends of these eccentrics have gear wheels f, at their inner ends which mesh into each other and the shaft a', of

the eccentric H', extends some distance beyond the back side of the upright A, to receive a fly wheel I, and a driving pulley J.

The upper part of the shaft, F, passes between the eccentrics H, H, and the eccentrics are at such a distance apart, that when their prominent parts are in contact with the shaft they will clamp or grip the same, but their depressed parts do not come in contact with the shaft. The form of the cams or eccentrics is clearly` shown in Fig. 2.

On the shaft of the eccentric H, a tappet K, is placed. This tappet as its shaft rotates works against a friction roller L, which is placed on the upper end of a vertical rod M, the upper end of the rod being bent in the form of a crook and encompassing the shaft of the eccentric H, the crook forming a guide for the rod, see Fig. 3. The'lower end of the rod M, is attached to arm N, which is attached to the outer end of a shaft O, which passes through the up right A, and has an arm g, attached to it. The outer endof the arm g, has a pawl 71. attached see Fig. 4.

The inner part of the table or bed D, rests on a friction roller P, which has its aXis tted on the arm a. The outer end of the arm N, is attached to spiral spring Q.

R, R, are two cutters the upper ends of which are fitted in the weight G, in V-form as shown clearly in Figs. 5 and 6, Fig. 5, being an inverted plan of the weight G. 'Ihese cutters are made of steel and may be secured in the weight G, in any proper way, the cutters being sufficiently long so as to project far enough below the weight to pass th? requisite dist-ance into the wood to be sp 1t.

The operation is as follows: Motion is given the shaft a', in any proper manner and the sticks of wood to be split are placed uprightly on the table or bed D, near its periphery. The tableor bed D, is rotated intermittingly in consequence of the tappet K, actuating the rod M, which in turn operates the arm N, and consequently the arm and pawl g, p, the latter catching into the rack E. The downward movement is given the rod by means of the spring Q, in cer` tain cases however t-he rod M, may be sufliciently heavy to fall by 'its gravity and no spring would then berequired. The shaft F, is raised by the prominent parts o-f the eccentrics H, H, and falls by its own gravity solely when the prominent portions of the eccentrics leave the shaft, the buer al, striking the guide b. The sticks S, as they pass underneath the cutters R, R', are split, by the descent of shaft F, and cutters, into small pieces of suitable size, one cutter R, splitting the stick into slabs, and the other cutter R', cutting the stick at right angles with cutter R. These cutters do not both act at the same time on the sticks but successively, the cutter R, acting last upon the wood, and re-splitting the slabs cut by cutter R, see Fig. 6, in which the black diagonal lines show the cuts of cut-ter R, and the red dotted lines the cuts of cutter R, the red arrow showing the direction in which the table or bed moves. The feed of the table or bed D, may be varied as occasion may require byY att-aching the lower end of the rod M, nearer to or farther from the outer end of arm N.

The cutters R, R', may b readily sharpened when dull, as they are straight plates of steel, and may be easily attached to and detached from the weight G, and as the two cutters act successively on the sticks S, the sticks are cut with but a moderate sized weight Gr, and the operation of the machine greatly facilitated. d

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

The intermittingly rotating table or bed D, in combination with the vertical reciprocating cutter shaft F, arranged to operate substantially as and for the purpose set forth.
