s IMPROVEMENT |N sHiNGLE-MACHINES.

Specification forming part of Letters Patent No. 150,480, dated May 5, 1874; application filed i February 28, 1874.

To all whom it may concern:

Be it known that L'SrENoER B. PEUGH, of

"Salem, in the county of Washington and State of Indiana, have invented a new improvement in ShingleLMachines for sawing shingles, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a top View of my attachment to sawmill carriage for sawing shingles; Fig. 2, a vertical transverse sect-ion of the same on the line c c, Fig. l; and Fig. 3, a detail side View of block, showing manner of cutting the shingles, with alternating butts and points.

Similar letters of reference indicate corresponding parts.

The invention will first be fully described, and then pointedout in. the claim.

A in the drawing represents a carriage of the usual construction, for moving the log against the circular saw. To the outermost lateral head -hloeks B of the carriage ,are hinged lever-rods C, which turn on pivot-pins a, placed nearly levelwith. the top of blocks B. Rods C extend sidewise along the headblocks, and connect at the rear ends, by p ivoted links b, with a longitudinal crank-rod, d, which is supported in staples or hinges c ot' the side piece of the carriage, and turned by means of a hand-lever, f, at one or both sides. Links I) are pivoted to the arms of the cra-nkrod d at such a distance from the same that the lever-rods C may be thrown alternately into inclined position, as required, to feed the shingleblocks to the saw for obtaining the tapering shape of the shingles. The position of lever f is changed after the carriage has passed the saw, and retained during the' time of passage by means of suitable rack or ratchet ,arrangement- The block'fastenin g frame D is guided, by railsg, along the lever-rods C, and moved toward and fromthe saw in the same manner as the logs. The extent of motion of frame D is defined by bottom stops It, which come in contact with the pivot-pins a of the carriage, and rear stops h .of head-blocks B.

4from each block.

is then changed for the next trip by lever f, p

top jaws F are swung on the top of the blocks, v The top jaw.

and iirmly driven into the same. F is of U shape, as shown in Fig. 1, and has sharp teeth or spurs t', which enter into the block, and hold the same iirmly in connectionl with the teeth of the lower jaws F.

The shinglefblooks are out from the log in the size of the shingles required, iirmly attached to the block-fastening fra-ine D, and

fed, by the motion of the carriage, to the saw. Each trip of the carriage cuts off a shingle The inclination of the block so that shingles with alternating butt and point ends are cut from the blocks. The regular size of the shingles is then produced from the sections so cut by ripping them to proper width by a smaller saw.

The blocks are cut oli' into shingles as fast as a log can be cut into planks, so-that shingles are thus produced, by a simple arrangement, out oi the whole blocks without any splittin g. u

The block-fastening frame maybe easily taken off when not required, and the carriage then used for the ordinary purposes.

Having thus described my invention, I claim as new and desire to secure ily-Letters Patent The d etachable shin gle-block-fastenin g frame D, constructed of recessed pieces D with projecting stationary bottom jaws F, and pivoted top jaws F', substantially as set forth.
