IMPROVEMENT IN SHINGLEv-MACHINE.

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

To all 'whom it may concern:

Be lit .known that I, ASA'NEWELL, of Jordan, in the county of Onondaga, and State of New York, have invented a new and improved Shingle-Machine; and I do hereby declare that the following is a` full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specication, in *whichi Figure 1 is a side view of my invention, and

Figure 2 is a vertical longitudinal section of the same.

Similar letters of reference indicate like parts.

My invention consists- First, in so arranging two froes as to act on opposite ends ofthe bolt.

Secondly, in the arrangement of automatically-operated shaving-knives and feed-rollers with relation to the froes.

Thirdly, in the arrangement of a table, which supports the bolt, and is automatically elevated and depressed by the action of wedgesoperated by means of the free-carrier.,

Fourthly, in the arrangement of a fixed stop with relation to the froes and adjustable table.

Lastly, in the arrangement, with relation to the froes, feed-rollers, and knives, of gearing, and mechanism for operating the same, all as hereinafter set forth.

In the accompanying drawings- A is a movable table,"or bed, on which the shinglebolt is laid for living;

Y Bis the main froe, or riving-knife;

c c, fig. 2, are the shaving-knives; and

D l) are rollers, for drawing the shingles through said shaving-knives c c.

The shingle-bolt is placed upon the'table A, and the froe B is thrown forward, by' a pair of side-levers, G, and whenthe froehas out a shingle from the bottom of the bolt, the free then passes onward under the bolt-holder, or rest H, and the table A and the riven shingle are then elevated by the wedges I a, g. 2, so that on the return of the froe B, its rear side catches the shingle, and pushes it to the shavingknives c c, until the rollers D D are enabled to seize the shingle and relieve the froe in the duty of passing the shingle through the shaving-knives.

As soon as the froe has reached the backward termination of its stroke, as shown in the drawings, the table A again falls, and drops the shingle-bolt, to the thickness of a shingle, below the edge of the froe B, and as the froe advances, another shingle is cut from the lower side of the bolt, and the froe again passes under the rest H, until the table A is elevated so that the back of the froe can catch the severed shingle and push it to the shaving-knives, and the second shingle is made; and so the operation continues.

The table A is elevated and depressed by wedges, I a I a, iig. 2, the wedges a beingl fixed to the lower side of the table, while the wedges I I have a sliding movement, and are operated by tappets, on the lower sides of the slides J, which carry the froe B,'said tap,- pets engaging with arms t', iig. l, projecting from the wedges I, through slots in the side ofthe machine.

To prevent the out ofthe main froe B from running out toward the opposite end of the Shingle-bolt so much as to present the grain of the wood unfairly to the froe, by the first end of the bolt being cut away too fast with relation to its opposite end, a second froe, b, is added, which cuts into the opposite endl of the bolt for a short distance, and then retreats before the advance ofthe main froe.

This secondary froe b -is driven by a pair yof sidelevers, g, and slides, j, in a manner similar to that of themain froe,'but makes two strokes to one of the main froe, so that both froes are free from the shingle-bolt when the table A is raised or lowered, and at the same time allow the main froe to advance beyond the shingle, and push it to the shaving-knives c c. v

`The rest H is for holding the shingle-bolt in place, and is constructed in such manner that the froes may pass under or beyond it, as shown in g. 2.

The lower feed-roller, I), runs in iiXed bearings, but the bearings of the upper roller, D', rest in boxes K, which slide vertically in the frame-work, so that the said feed-rollers accommodate themselves to the variable thickness or taper of the shingles. v

The boxes K are pressed down by spiral springs, k, and give the feed-rollers their elastic gripe on the shingles as they are passed through them.

The shaving-knives c c are set in movable boxes, C C', which have a vertically-sliding movement, to give the tapering shaving-cut tothe shingles.

These boxes C C are operated by cams on the main shaft, E, fig. 2, the boxes ofthe lower knife c making connection with shaft E by cam-rods, e,- ig. 2, on thel inside of the machine, and the boxes C', of the upper knife, make connection with the cam-shaft by camrods m, fig. 1, passing down on the outside4 ofthe machine or frame-work.

The feed-rollers D are connected together at one end by matched gears t.

The driving-power is applied to the main shaft E,

`and the various devices and instrumentalities are so connected, by means of gears N F S R, connectingrods f r, and cam-n1ovements E e, that all the move ments are timed with relation to each other, and act in concert. I

By these means, I produce by machinery the superior quality of shingle made heretofore by hand-work only, and known as the shaved shingle.

I am aware that shaving-knives4 have been used in connection with feed-rollers; I am further aware that the upper knife has been operated to and from the lower stationary knife, by means of a peculiar connection with a horizontal shaft; but I am not aware that both knives have been thus operated, and unless both knives are operated, the taper of the shingle cannot be followed. Therefore, I do not claim the shavingknives when the upper one only is movable. Having thus described my invention,

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

1. 'lhe froes B b', acting in concert with each other, and upon opposite ends of the bolt, when operated by the means and in the manner described.

2. The arrangement herein described of the froe B, shaving-knives c c, and feed-rollers D D', when all the parts are constructed to operate as herein set forth.

3. In a shingle-machine, the arrangement of the table A, With the iixed wedges a, and the connected slid-` ing wedges It' I i, when operated automatically, by means of the reciprocating carrier J, all operating substantially as herein set forth.

4. The arrangementof the fixed stop H, constructed as described, with relation to the froes B b', and automatically-adjustable table A, all as herein set forth.

5. The arrangement of the arms g g G Gr, gear-wheels N F R S t, connectionsf ll', and sha-ft E, with relation to the froes B b, feed-rollers, and shaving-knives, substantially as herein described.

The above specification of my invention signed by me, this 4th day of November, 1868.

ASA NEWELL. Witnesses:
