Be it known that'I, JAMES E. AUSTIN, of the. city and county of Oswego, and State of New York, have invented a new and improvedShingle and I-Ieading-Machine; and I do hereby declare the following'to be a full, clear, and exact'descriptiont` the same, suiiicien't to enable those skilled in the art to which my invention appertains to make use of it, reference being had to the accompanying; drawings forming part of this specification, and in whichi 'i' i i i 'Figure l is a cross-section through the line a: a: of fig. 2.

Figure 2 is a side elevation, and

Figure 3 is atop view. 4

In this invention a new apparatus is provided for heading and pointing the shingles, and it is so constructed that by throwing a vportion ofit ont of gear, thc stnffcan he sawed into thin boards oi' a uniform thickness, suitable for barrel-heading. l f i In the drawings, A, A-represen`tslthc frame of the machine; B, the vdriving-shaft; b, the drum, to which is applied the power that operates thedriving-shaft; b pulleys, from which the parts that work the carriage are operated; S, the saw, and C the carriage. The driving-shai`t B forms the saw-mandrel,.and stands in an upright positioii, 'the saw resting horizontally upon its upper end.

The carriage is slid back and forth longitudinallywith the machine, upon ways, Wv W`,-by means of a pit-` man, P, 'A horizontal-shaft, D, at the end of the machine, works the pitman, the latter being connected with a crank or wheel, F, and eccentric-pin, attached to the shaft. The shaft receives its motion from aworm-screw shaft,'E, which in its turn-is operated from the driving-shaft hy means of a belt and pulleys, p p, working in connection with thc pulleys b b. The worm e, and cog-wheel F, are brought into or thrown out of gear by a lever, G. In this manner, as the driving-shaft rotates the saw, it also commnnieates'a reciprocating 'motion-to the carriage, which runs back and forth above-the saw, parallel to it, and'almost in contact with The carriage is provided with two boxes, II II, for holding the bolts to be sawedfeach box having ar-e'cess, h, in its side, toenable theoperator totake hold of the bolt more easily for the purpose of adjusting or moving it. The boics are loose, resting in apertures made in the carriage to receive them, and supported by flanges or rims, that rest upon the carriage around the apertures. Each h ox is provided with a sliding end-piece, I, operated by a stout curved spring, J. The spring presses the end-piece in towards the centric of the box against the bolt, to hold the latter firmly in position while passing the saw, butrwhen the carriage has conveyed thebolt past the saw and back, as it approaches the point whence it started, the spring strikes against a pin, z', and is forced back, carrying theend-piece with it, and allowing the bolt to drop down. Y

A pivoted plate, K, of the formshown clearly in iig. 3, is attached to one side of the carriage, and lies npon its upper surface, having arms, .7c 7:, reaching out on either side, `with sharply-bevellcd ends, which run under the inner rims or flanges of the boxes II H, and, as the carriage runs back and forth,-alternately raise the inner odge of one box or the other. This plate-is moved by pins, a a, against which the end of. it strikes, and it so operates that'as the carriage reaches the end of its forward movement, the plat-e K slightly raises the inner edge of the box, and with it thel bolt, holding it up while thc carriage is ruiming back, in order to preventnthe 4friction of the bolt against the upper surface of the saw. As the returning holt clears the edge ofthe saw,

the arm is withdrawn, and the box let down to a level position again, while at the same moment, as beforev explained, the sliding end-piece I is retracted, and the bolt is dropped for a new cut.

The shingles are headed and pointed by an arrangementshown very clearly in section in iig. 1. In that figure, L is a rest or table, upon which the holt drops when the end-piece I is withdrawn. One of these tables is situated at each end of the machine, its inner edge lying under the edge of the saw. The table lies'across the machine, and is pivoted at its centre, so that its ends can bc rocked up and down upon the pivot. The ends of each table rest upon a sliding block, M, provided with inclined or inward-sloping shoulders, m m, which, as the block is slid hack and fort-h across the machine, cause the table to rock on its pivot. A pitman, N, extends from the end of `the'sliding block to a crank or eccentric, n, upon a shaft,. O, which works at the vside of the machine, receiving` motion from the shaftD by means of suithble'gearing, o o. The ptmen may be attached to the cranks or eecentrics, n n, 'in such a way that they can he readily detached. For this, purpose they may he simily provided with a notch in their under sido, which may rest over the pin when sawing shingles, and :xt

other times maybe lifted off by means of handles, r a', attached to the pitmen.

-The operation of 'this machine is simple arid e`eetive', and adapts it. to the manufacture of 'shingles or-of` plain barrel-heading of uniform thickness. When shingles are to be sawed; the pitmen N N are connected with the cranks Vn n., as above described, and the table L is thereby caused to rock' upon its pivot, v. `The gearing 0 ois so adjusted in making the machine that the inclina-tion of thetable L is reversed at every return of the"l carriage C, so that as the bolt drops upon Athe table once, oneend of it will be higher than the other, and as it drops again, after thc cutting of a shingle from it, the inclinationwill be reversed, thus causing the shingles to beheaded and pointed.

When it is desi-red to sawbarrel-heading, or stu men N N may be unshipped, and the sliding blocks M M'adjusted to hold the tablelall the ytime in'a perfectly horizontal position, so as tosaw'all the material into strips of a uniform thickness. Y

The elevation of the tableL may be adjusted by means of set-screws Z Z, (so that thc material produced'by the' machine shall'be of any required'thickness, from that of veneering up to that of heavy planks.

Having thuis described my invention, what I claim as' new, and desire to secure by Letters Patent, is-'' if for making boxes, and other thin Wooden strips, the pit- The combination of' the pivoted tables L L with the sliding blocks M M, havingr the, shoulders' m 111, and t operating tho tables, substantially in the manner and for the purposes specierjf l JAMES E. AUSTIN.
