IMPROVEMENT IN SHING'LE-MCHINE.

The Schedule referred to in these Letters Patent and 'making part of the same.

To all whom. tt may concern Be it known that I, DUNHAM WLKEs, of' Nineveh, in the county of J obnson, and -State of Indiana, have invented a new and 4useful Portable Shingle-Machine; and I do hereby declare the following to be a full, clear, and exact description of the same, sufficient to enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-,-

Figure lis a front view of the device illustrating my invention.

Figure 2 .is a sectional plan view in the line 2 z,

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

` My invention relates to an arrangement'of the gearf `ing o'f a portable shingle-machine, as hereinafter more fully set forth.

In the drawings- A A represent the sill-pieces, to which are' secured uprights B, which are connected together at the top by a cap or cross-piece, O.

D represents a table or platform, which is secured to the uprights, and intended to support the timber while being presented to the knife.

. A shaft, E, is 'mounted on the sill A', and carries on one end a crank or erank-wheel, a, to which is connected a pitman, b, which is joined to the lower end of a sliding frame, vF, which carries a knife, G, and gauge H.

A. toothed wheel, c, is mounted on the shaft E, which gears with a pinion, d, mounted on the driving-shaft J, whose bearings, on one'side, are on an arch or frame, K, which is elevated above the sill A", and the other side ison an auxiliary upright, B', extending parallel with the upright B.

Ihe shaft J also carries the ily-wheel w and pulley e, the former of which revolves between the crosspiedces B B.

A staple, L, is hinged'to each end `of the sills'AA, said staples being `of ordiuary construction and form.

It will be seen that the frame and working-parts, as thus described, form a portable device, which, when carried to any intended spot, may be rmly held in place, by driving wedges or stakes through th'e staples against the ends of the sills.

The frame F slides between" the uprights B and the knife G, which is secured to said sliding frame F, has a cutting-edge of|two diagonalfaces, which are brought down against and ont through the timber when the frame isv lowered, through the mediumof theoperating-mechanism. p

The gauge H consists of a dat plate-of metal, extending iu line with the knife G, and formed with ears or lugs, through which passes a pivot-rod, M, whose ends enter the eyes of screw-bolts N, which are4 supported and guided in block O, secured respectively to the middle and lower cross-pieces of the frame F.

These screw-bolts'are readily operated through the medium of screwnuts or taps n, working on the blocks, and allowing the gauge to be set relatively to the thicknesses ofthe shingle tothe cnt. r The gauge is to be adjusted relatively to the set or taper ofthe shingle, by means of screws P, which pass through the middle cross-bar, and bear against the ends of the gauge.

The operation is as follows;

The timber is split into broad blocks, from four to eight inches thick, and from six to eighteen broad, owing tothe size ofthe timber, the broad part of the block being split across the grain of the timber, .so that the grain or splitting way of the timber is across the block in the thin way. y f

After the timber has been well steamed, a block is placedon the table with the edge down, from which `he intends to begin toont theshingles.`

Ast-he knife ascends, the operator slips the broad side of the block under the knife. As it descends, he ltakes oli' a thin slip, barely suiicient to face the block and makethe shingle straight. It is then placed, with the face side down, on the table, and the edge from which he intends to out theshingles, as the knifev ascends, is slipped under and faced. The block is here set up on the faced edge, and the other side faced,-as before, and the block is now ready to heout into shingles. The operator now observes the: grain of the timber at the edge of the block, and places that side of the block down, which causes theV grain at the edge of the block to tend slightly tothe knife downward, and then takes hold on each end of the block, and, as the knife ascends, he slides it against the gauge-bearing, ateach stroke of the knife, sniiciently hard, 'rst with right hand and then with left, to turn' the gauge, y

making thethick end of the shingle rst at oneend and then at the other, until the block is cut up, unless the grainof the tirn'ber begins to run with the edge of the knife, or tendtoward the block downward; then the block must be turned bottom side up, with the same edge to the knife, which sets the grainl right with the knife, and the block is finished, as previously described. I will remark, that so long as this rule of keeping the grain of the timber tending slightly toward the knife downward, the shingles will always be as solid as if sawed or shaved; but. if the grain in the wood begins to run with the edge ot' the knife, ortend into the block downward, it begins to come in line with Athe face of the back part of the knife, which is bevelled or wedge-shaped, and begins to draw into the block, and crack or spoil the shingles. On the oontrary, when the grain 'of the timber is tending slightly toward the knife downward, the front face of the knife being straight, it cuts smoothly through the block -without drawing the knife, and the grain of. the timber in the shingle, as it comes o, stands bracing to ward the knife, and will not curl from the knife, but will come off solid and true. For this reason, I attach no feeding-apparatus to my machine.

The screws N" are vdesigned to move the gauge iu or out, to'suit the thickness of the shingle, and the screws P can be set'in against the end ofthe gauge, so as to prevent it from turning on its pivot, and make straight shingles,.i desired. Experienced operators can use it in this Way for. jointng the timber before cutting into shingles.

Having thus described my invention,

NVhat I claim as new, and desire to secure by Letters Patent, is

lhe arrangement o f gearing c d, shafts E J, elevated bearing K, y-wheel w, and pulley e, in 'connection with knife G, and gauge H, uprights B B,sills A A', and staplesl L, to form a portable shingle-machine, as described. I

llhe above,.signed by me, this 20th day of J uly, 1869. DUNHAM WILKES.
