i Letters Patent No. 88,250, dated March 23, 1869; mttedctted lfarch 18, 1869.
IMPROVEMENT IN' MACHINES FOR SPLITTING- WOOD.
The Schedule referred to in these Letters Patent and making part f the same.
To all lwhom fit may concern.-
Be it known that I, WILLIAM L. WILLIAMS, of thev city andState of New York, have invented, made, and applied to use a certain new and useful Improvement in Machines for Splitting Iiiiidling-llooll;- and I do hereby declare the following to be a full, clear, and eX- act description of the said invention, reference being had to the annexed drawing, making part of this specific-ation, wherein- Figure l is a plan of said machine;
Figure 2 isa vertical cross-section at the line x x and Figure 3 is a similar section at the line y y and Figure 4 is an elevation of the sliding bed and feeding-wheel.
Similar marks of reference denote the same parts.
Machines-have heretofore been made for splitting kindling-wood, in which the wood is caused to move along through the feeding-trough by means of chains, but the concussion and the splinters of wood are apt to interfere with the chain operating satisfactorily.
The nature of my said invention consists in a pair of horizontal-toothed feeding-wheels, placed at the sides of the trough, and mounted so as to yield to inequalities in the wood that is fed along by them to the cutter, said feed taking place when the cutter is out of the wood. I also provide means for adjusting the plate `that holds the wood down as the cutter rises.
In the drawingw represents the bed of the machine, upon which are placed two stationary side pieces, b l), forming a trough for the reception of the blocks of wood, placed up endwise within said trough.
Above the bed a is the frame c, carrying the shaft d, with its 'crank e and pitman f, to the sliding headblock g, that carries the cutting-knives h, that: are placed diagonally to the trough a b, as seen in g. 1.
The rot-ation of the shaft d causes the reciprocatiou of the knives h, and in splitting blocks of wood of usual length, it is not necessary for the knives to come within about two or three inches from the bed a; but if very short blocks were introduced, for making fine kindlingmaterials, the knives would not pass sufficienti y far into the same to split them, aud if the knife itself were raised or lowered, there would be dificulty in the adjustment, and risk of the parts becoming loose.
I therefore make use of a movable bottom, 7:, to the trough, held in place by ribs at the ends, taking against the end-portions of the bed a, as seen in the detached section, fig. 5.
rlhis movable bottom, k, supports the short pieces of wood, andcauses the knife to pass suiicientlyuear tothe surface upon which they stand, to insure the splitting.
lIn order to accommodate the varying points at which the upper ends ofthe blocks of wood will stand in the trough, according to the length of the blocks, I make use of an adjustable plate, t', through slots in which, the knives h pass; and
l l are screws, that are -actuated by the gearing m aand cross-shaft o, so as to raise and lower the said plate t uniformly on the two sides, so that it shall remain parallel with the bed a.
The projecting portions ofthe plate a pass through slots in the frame c, and are guided thereby.
This adjustment may be applied to the frame carrying the rollers, as in my patent of December 12,1865.
I provide side-bars p above the pieces b l), which sidebars 1) are attached in place by bolts 2 2, at one end of the machine, and near the other end of the machine are standards 3 3, between which, and said bars p, are springs, so that the bars p will yield to undue strain, laterally, that may be caused by the knives passing into the wood andspreading it.
The horizontal feed-wheels gare formed with pointed teeth projecting around the periphery, and the vertical shafts 4 passl through sliding beds lr, that are fitted to move at right angles, or nearly so, to the trough, and these beds are formed with pendent arms fr that carry the cross-shaft s, upon which are the bevel-gears t, taking corresponding gears u upon the shafts-4.
The gears tare fitted with sliding keys, pins, or feathers', so that they may move endwise of said shafts, but be turned thereby; and
w is a ratchet-wheel, to which a lever, 5, and pawl, 6, are applied; and
7 is a connecting-rod to a crank-piu on the shaft d.
'The parts are so placed that the wood is fed along by the wheels q, at a time when the knives are above the wood, and said feed-wheels stand still While the knives are splitting thewood.
The feed-wheels pass the wood forward to the cutters with regularity, and yield suiiicientlyv 'to pass through large or closely-packed pieces, or spring up to maintain the hold l,upon smaller or less closelypacked pieces.
What I claim, and desire to secure by Letters Patent is 1. The horizontal yielding and toothed feedingwheels q, arranged at the. sides of the feeding-trough, and actuated substantially as specified, to move the set forth.
2. The side-bars 1;, extending from end to end, or nearly so, of the trough b, and united by a bolt at the ends, where the wood is entered, and provided with springs near the other ends,'for the purposes and as set forth.
3. The plate, or frame, adjusted by screws, as specied, in combination with the feeding-trough and reciprocating cutters, substantially as set forth.
In witness whereof, I have hereunto set my signature, this 12th day of August, 1868.-
W. L. WILLIAMS.
