IMPROVEMENT IWOHINES FOR sAwlNe sHlNGLEs.

Specification forming part of Letters Patent No. 179,568, dated July 4, 1876; application tiled May 9, 1876.

To all whom it may concern:

`Be it known that I, ERAsTUs P. KIDDER, of New Alstead, Cheshire county, New Hampshire, have invented an Improvement in Machines for Sawing Shingles, of which the fol-A is more convenient to manipulate 011 the car` riage.

vFigure 'l` is a front elevation of my improved shingle-machine, and Fig.2 is a sectionalelevation On the line :v fr.

Similailetters of reference indicate corresponding parts.

A is the saw, which I prefer to make about three feet in diameter, or of any convenient size larger than the length ot' the bolt and fit it on the mandrel B at the ext-reine end. C is the carriage, on which the bolt rests for being presented to the saw, said carriage being connected at the ends to cross-head D by bars E, which are also slides running on the rods F, up and down which the carriage is worked by the Crank-shaft G and connectingrod H, which are geared with the saw-arbor,

or may be operated in any other way. J is the gage by which the thickness of the shingles is regulated, and it also gages the taper by being pivoted at the center L, so that it will tilt forward and backward at the ends to shift the block tocut heads and points in opposite directions alternately. M represents the discharging-chute, which is located back of the saw, to catch the shingles when they drop from the block and throw them oft'. It slopes downward from thelower edge ot' the saw, and is hinged at N, to be raised by the shingle and drop back into the place after the shingles pass it.

The bolt lies on the carriage C, withone end against the gage O, where it is held by the attendant. It can be first trimmed on one side, and then turned upon the trimmed side to be sawed, by which the shingle will have one side dressed.

Having thus described my invention, Ielaim as new and desire to secure by Letters Patent- The combination, with saw A, arranged on the mandrel B, as shown and described, of the eentrally-pivoted gage J and the carriage G, connected with cross-head D by verticallysliding bars E, as and for the purpose set forth.

ERASTUS P. KIDDER.
