TO ALL WHOM IT MAY CONCERN:

Be it known that I, H. WOODMAN, of. Saco, in the county of York, and State of Maine, have invented al new and improved Shingle-Machine; and that thev following description, takbn in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements by which my invention may be distinguished from all others of a similar c lass, together with such Yparts as I c laim, and desire to have secured to me by Letters Patent.

This invention relates to a new and improved machine for sawing and planing shingles; and it consists of a rotary .feed-table, circular saw, and rotary planer, all arranged and combined to operate in the manner substantially :rs-hereinafter set forth. Itthe accompanying sheet of drawings- AFigure V1 is a side view of my invention. Figure 2, a plan or top view of the same. `'Figure 3, an enlargedsection of the feed-wheel taken in the lino zz, fig. 1; and Figure 4 isthe same view as fig. 3, with the screw-wheel shaftin a different position. Similar letters offreference indicate corresponding parts.

A represents a framing, which 'may beV const-ructed in any proper manner to support the working parts. B is a horizfontal shaft, placed on the upper part of the framing A, and having a circular saw, O, at one end of it. D is a horizontal shaft at one end of the framing, and having a toothed wheel; E, at.one end of it, into which a pinion, F, gears, said pinion being at one'end of a horizontal shaft, G, in the lower end of the framing. Th'e shaft G is driven by a belt, I-I, from the saw-shaft B,`said belt passing around a lever-pulley, I, on the shaft G, which is connected with the shaft by a clutch, a, the pulley I being moved so as to be engaged with or disconnected from the shaft by means of a lever, J, (see fig. 2.)V The wheel E constitutes thc feed-table, and it has a number of rectangular openin'gs in it to receive the bolts from which the shingles are cut. Three of these openings are shownin fig. I, but more or less may be used. At each end of each of these' openings there is a grooved cylinder, K, having a pinion, L, at one end, into which screw-wheels M M on a shaft, N, gear, (see more particularly Eg. 3,) and at one end of the shaft N there is a dog, O, composed of four radial arms b. One of the Vgrooved cylinders K is tted in an adjustable frame, I), which is moved or actuated by a lever, Q, the latter being held in position by a segment-rack, R, on the wheel. A spring, S, on this lever, bears against the frame P, as shown in fig. 1. Thisv adjusting-movement of one of the grooved cylinders is necessary in order that bolts of diiferent lengths may be secured 'between the grooved. cylinders, and the spr-ing S admits 'of one of the grooved cylinders yielding to compensate for any irregularity in thc length of a bolt. The screw-wheels M M are each provided with two spiral anges, c c, a portion of each flange having a spiral, I, and a circumferential part, 2, as shown invfig. 4. On the upper part of the framing there isla projection, d, for the dog O to strike against as the wheel or feed-table E rotates, said projection extending over the upper part of the feed-table.

On the upper part of the framing A there is secured a metallic adjustable frame, T, having a shaft, U, secured in it. To one end of this shaft there is secured a rotaryY planer, V, which may be constructed in any proper manner. A cutter or chisel, e, at each end of an arm, W, will answer the purpose.

When the machine is in operation, the wheel or table E rotates inthe direction indicated by the arrow I, and the saw C cuts a shingle from each bolt, and the planer V smooths4 the surface of each bolt as they pass from the saw, on-e side of each shingle being planed, which ofcourse is all that is necessary. The bevel or taperis given the'shingles by the feed-mechanism, which presents the bolts to the saw, cach bolt being fed inward inconsequence of an arm, b, of the dog .0, 'coming in contact with the projection d, the shaft N being turned thereby a quarter of a revolution.l Both ends of the bolts are not moved the same distance at each feed-movement, the yends being moved alternately, one more than the other, in order that the shingles may be cut in taper form. 'This is elected by having the spiral and'circumferential parts 1-2, of the ilanges C, of the screwfwh'eel M M arranged' in such relation with each other as vto cause the' difference of movement specied, theends of the bolts being moved alternately inward, towards the cutting-plane of the saw, and the shingles consequently sawed in proper taper form. I design t'o have the shingles, as they are cut, fall upon an elevatorapron, X, which conveys them up to an edging-saw, Y, at one side of the framing.

Having thusfdescribed my invention, what I claimas new, and'desire to secure by Letters Patent, is-

l. revolving table, with its feeding and s ecuring-tnechanism,` constructed vsubstantially as described, in combination with the rotary planer .V and saw C, as and for the purpose specified.

2. The combination and arrangement of the outer grooved cylinders K, adjustable frame P, lever Q, segment- HORACEl WOODMAN.
