` SPECIFICATION forming part of Letters Patent No. 290,222, dated December 18,1883.

Application tiled October 15, 1883. (No modem .To all whom t 11mg/ concern.-

Be it known that I, JONATHAN l?. FERREN- BURG, a citizen of the United States, residing at New Madrid, inthe county of New Madrid and State of Missouri, having invented certainv new and useful Improvements in Shingle- Machines; andI do herebydeclare that the following is a full, clear, and exact description of the same, reference being had to the anneXed drawings, making a part of this specication, and to the letters and gures of refer-- ence marked thereon.

Figure lof the drawings is a side elevation of my improved shingle-machine, partly inlongitudinal section, and showing it connected to the driving mechanism. Fig. 2 is a perspective view of the machine; Fig. 3, a perspective view in longitudinal section.

The present invention has relation to certain new and useful improvements in machines for cutting shingles and the object thereof is to improve the machine in the several details of construction, whereby the operation of cutting the shingles is rendered more simple and practicable, and enabling the shingles to be cut from the blockand completed with great rapidity, the shingles being rived and automatically placed in position to be shaved, thus completing the operation without .the necessity of handling the shingle after being cut from the block. These several objects I attain by the construction substantially as shown in the drawings and hereinafter described and claimed. I

In the accompanying drawings, A represents a rectangular frame of any suitable construction, having upon its interior longitudinal grooves to receive the sides c of a carrier, B, which is in form of a skeleton frame. This carrier Breceives the wooden block frornwhich the shingles are to be cut, said block resting on and being supported by the stationary platform C. The carrier B is caused to have a horizontal reciprocating motion lengthwise of the frame A, the sides a of the carrier located in the grooves upon` the interior sides of the frame guiding the carrier in its movement. The forward end of the carrier B is of less depth or thickness than the rear portiony of the carrier, so that a portion of the front edge of the wooden block will be exposed the carrier B makes one motion.

to the action of the cutting-edge of a stationary knife, D, as the block is forced against it'V by the forward motion of the carrier. This knife D is arranged crosswise or transversely of the frame A, its' ends being supported in the sides thereof, and above .its ends are located spiral or rubber springs b, their tension regulated by set-screws or other means usually employed for the purpose. By this means the knife Dis given a yielding motion of any necessary degree to conform to the irregularities in the wooden block. Every time theblock is forced against the knife it cuts therefrom a piece from which the shingles or shingle is made in the completion of the operation. The-piece, as it is'cut from the block, passes down in contact with a knife, E, which is permanently attached to ahorizontal sliding frame, F, having its guides in the sides ofthe frame A. This frame F, as it passes in an opposite direction to the forward motion of the carrier B, will cause the knife E to be forced against the piece already cut from the block, severing it in two pieces. As the frame E passes forward in an opposite direction it will crowd the lower half of the piece last cut between the knives G, which commences at the butt of theshingle and shaves both sides at once, tapering toward the top thereof.

The frame F is provided with dividing-bars d, extending forward and between the knives G to the end of the plate H, and are formed tapering as they pass between the knives, so that it will admit of the latter coming nearer together, and thus make an angular cut to give to the shingle the proper slope.

It should be understood that the frame F makes two motions forward and back, while Thus it will be seen that the two pieces last cut, which are to form theshingles, are completed as rapidly as the pieces are cut from the block by the knife D.

The extremities or ends of the knives G project through and beyond the sides of the frame IA, and arelkept pressed against the dividingvbars dby suitable springs, preferably of rubber, as shown at e. To the ends of these knives G are secured wire braces f, which are in turn connected to the sides ofthe frame A byv screws or other suitable means, and, if de- Ico sired, set-screws may be employed as an additional means, both above and below the projecting ends of the knife-bars or knives G, to retain them in proper working position.

The several knives are composed of steel, and the knife E has sufficient elasticity to spring up or yield in case of theshingles splitting thick, and, if desired, may be adjustable to increase or diminish its height, said adjustment being preferably made by set-screws or any of the usual means.

rIhc frame F, at its forward end,has connected to it a plate, I, and, like the plate I-I, extends the entire width of the frame A, the knife E immediately adjoining the inner edge thereof, as more clearly shown in Fig. 3.

To the under side of both the plates II I are connected spring-guides K, which consist of curved plates having interposed between them and the plates II I spiral or other suitable springs, so that the curved plates will yield, but bear against the shingle sufficiently to hold it in proper position when passing under the guides.

A platform, L, is connected to the sides of the frame A in such manner as tohaveayielding motion when required, the front end of platform resting on spiral or rubber springs g. The front of the platform Il or the outer edge thereof is on the same horizontal plane with the cutting-edge of thelower one of the knives G, said platform supporting the shingle, and the pressure thereon of the guides K holding it in position while it passes between the knives.

The knife D, if found preferable, may be so supported in the sides of the frame by setscrews or any other well-known means that will admit the height of the knife being adjusted.

'lhe machine may be made of any suitable material, either wood or metal, or both, and is supported by a suitable frame, M, at the required height.

rlhe means which I preferably employ to impart to the frame F and carrier 'B the neoessary vibratory or reciprocating motion is as follows: A large pulley, N, over which passes the belt h, extending to the drivingpower, is mounted upon a transverse shaft, z', and keyed thereto, so that said shaft will move with it. This shaft has its bearings in suitable boxes connected to the frame M, and has keyed to it a gear-wheel, I, the teeth of which mesh with those of a larger gear-wheel, It, arranged above it. The shaft t' has connected to it a crank-arm, 7:, witha pin, l, which latter enters the slot in an arm, mf, connected to the frame F.

To the hub of the gear-wheel It is a crunk n, connection being made with the carrier B by a pitman, p, pivoted thereto and to the crank, as shown in Fig. 1. The gear-wheel R has twice the circumference as the wheel I, so that at one complete revolution of the former the latter will make two complete revolutions, thereby, as the carrier has finished its movement forward and returned, the frame F will have moved twice as. fast and completed two of such motions; or, in other words, the carrierwill have one motion only to the frames two motions.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
