HALF TO JOHN M. STIEF, OF SAME PLACE.

SHlNGLE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 269,272, dated December 19, 1882. Application filed September 21, 1882. (No model.)

To all whom it may concern Be it known that I, AARON EMERIGK, of Johnsburg, in the county of Somerset and State of Pennsylvania, have invented a new and useful Improvement in Shingle-Machines, of which the following is a full, clear, and exact description,reference heinghad to the annexed drawings, forming part ofthis specification.

This invention consists of a shingle-sawing machine having a carriage provided with an automatically operating gage for the bolt, which gage is so constructed that by a slight movement of the bolt the butts of the shingles may be formed alternately at opposite ends of the bolt, in order that the latter may be reduced uniformly, and which is adapted to have.

a lateral movement to allow the shingle to drop with ease as soon as severed from the bolt, as hereinafter fully described.

In the drawings, Figure l is a side elevation of a shingle-sawing machine embodying my invention, and Fig. 2 is a plan view of the same.

A indicates a frame supporting the saw B and the carriage O. The carriage, which is supported on rollers in the usual manner, is provided with a guide-rod, D, on one side or onderneath one side, to which it is to be connected by loops or eyes, and a gage, F, pivoted to a projection on its rear end. The gage extends along at the side of the carriage, and is provided with three projections, a b a, on its surface adjacent to the bolt G, of which projections the central one, 22, is made longer than the others, in order that it may serve as a fulcrum for the bolt in adjusting the latter to contact with the end projections, 00, alternately, and may assist in supporting the bolt in either position. The bolt is to be held in either of said positions by hand, or, ifdesired, by any suitable expedient.

. The gage, which is adapted to-have a laterally-oscillatory movement by means of its piv- 0t, is provided with a guiderod, H, over which it passes and to which it is connected by an eye, E. The said guide-rod is provided with a lateral bend, a, outward from the plane ofthe saw, in order that when the shingle G has been severed or nearly severed from the bolt G the gage shall be thrown outofcontact therewith, to allow the same to fall from the side of the saw. The bolt is supported against the action of the saw by a block, I, secured to the carriage. I

In operation the carriage is moved to and from the saw by hand, and the bolt is to be adjusted in contact with the central and one of the end projections, a b a, previous-to each operation of sawing.

What I claim is l. 'lhecombination, with the fram'e,saw,and carriage, of the gage pivoted to the carriage and connected to a bent guide-rod, whereby a lateral movement shall be given thereto to release the sa wed -shingle, substantially as specifled.

2. The combination, with the frame, saw, and carriage, of the gage having projections, of which the central one is longer than the others, and connected to a bent guide-rod to give it a lateral movement, substantially as specified.

AARON EMERICK.
