SPECIFICATION forming part of Letters Patent No. 458,775, datedSeptember 1, 1891. y Application tiled January 6.1891. Serial No. 376,894. (No model.)

To LZZ whom t may concern.-

Beit known that I, OSCAR MELANQON, a citizen of the United States, residing at Davenport,in the county of Polk and State of Florida, have invented a new and useful Shingle-Machine, of which the following is a specification.

This invention relates to shingle-machines and the object of the same is to simplify the construction thereof.

To this end the invention consists of the machine hereinafter more fully described and claimed,and as illustrated in the accompanying drawings, in which- Figure 1 is a front elevatiompartly broken away. Fig. 2 is a plan View. Fig. 3 is a right side elevation. Fig. t is a plan View with the carriage removed. Fig. 5 is a central transverse section through the carriageand through the tripper. Fig. 6 is a perspective detail'of the tilter.

Referringto the said drawings, the letter F designates a suitable frame-work, in which is journaled in vertical position the main shaft M, the saw-shaft s, and the carriage-shaft c. Power is applied to a large pulley l on the main shaft, and the speed of rotation thereof is increased by the belt 2, connecting the large pulley 3 on the main shaft with the small pulley et on the saw-shaft s. A circular saw S is secured to the upper end of the saw-sh aft and turns in a horizontal plane. A belt 5 passes over fast and loose pulleys 6 and Y 7 on the main shaft and leads thence to a large pulley mounted loosely on the carriage-shaft c, which pulley is provided with pins 9 on its lower face.

K is a clutch splined on the carriage-shaft and having teeth It', adapted to engage said pins 9, and L is a lever having a weight IV at its outer end and centrally pivoted to the :frame-work, the said weight normally raising thein'ner end of the lever, which is connected to a groove in the clutch, and hence connecting the pulley 8 with the carriage-shaft, but disengaging the carriage-shaft and stopping the motion of the carriage when the outer end of the lever is raised.

The letter C designates the carriage, which is of circular shape and mounted upon the upper end of the carriage-shaft c. This carriage is preferably arranged, as shown, with openings to receive about three blocks from which shingles are to be sawed, each of which is of the following construction: The opening O is radial to the carriage and at its inner end has a stationary lip L2. In its side walls are grooves G, engaged by the tongues T of the movable block B, which carries the movable lip L', as shown. This block is pressed normally inward toward the stationary lip by a spring Q, standing between the outer face of the block and a metallic hoop H, which surrounds the carriage, and by this means the block from which the shingles are to be sawed is held in the opening. The movable block B carries a finger F', which projects over the hoop H and turns downwardly, so as to engage a tripper T, which is carried by the framework and whose operative face is slierter than the width of each opening D, and by this means at each revolution of the carriage the movable block B is tripped or moved slightly outward, so as to cause the movable lip L to disengage the block being sawed and allow it to drop.

Referring now to Fig. G, the lett-er E designates an eccentric-shaft mounted in suitable journals in the frame-work and havinga crossarin A on its outer end. I call this shaft an eccentric-shaft because it has eccentrics e on its body which stand at right angles to each other.

D is a frame pivotally mounted on a transverse rod CZ, which passes beneath the shaft E, and the side bars of this frame rest, respectively, upon the eccentrics e, whereby as the shaft F. is rotated the frame D will rock on its pivotal rod d.

Projecting from the carriage C, at a point justin advance of each opening O, is a shifterarm I, which strikes the arm A of the tilter and imparts quarter-revolution to the shaft E. By this means, after the blocks are locked in the openings, the lever L is lowered to engage the clutch-teeth k with the pins El, and the carriage commences to rotate, the tripper T causing the movable lips L to disengage the blocks as they pass that side of the framework. At each one-third revolution of the carriage a shifter-arm I strikes the arm A and turns the eccentric-shaft E, so that the frame D is tilted, and hence as the blocks are released from the lips and drop onto the frame they are caused to tilt slightly before they are again engaged by the lips. As the saw S saws shingles from the blocks, they drop in a pile and may be rremoved by an operator. When the blocks have been completely sawed up, the belt 5 is shifted from the fast pulley 6 to the loose pulley 7 by a beltshifter, (not shown,) or, preferably, the outer end of the lever L is raised and the pulley 8 disengaged from thecarriage-shaft c, whereby the motion of the carriage will be stopped, although the saw continues to turn. A new block is then secured in each of the openings O and the lever L allowed to drop, when the machine resumes operation, or the blocks may be placed in the openings O while the carriage is in operation, if the operator is skillful.

This machine is especially advantageous on account of the simplicity of its construction and the efficiency of its operation; yet I do not confine myself to the specific details of construction above described, as considerable change may be made therein without departing from the spirit of the invention.

of each opening, engaging the tips of said iingers and momentarily drawing said block outward and then releasing it, a tilter, substantially as described, beneath said tripper, and shifter-arms carried by the carriage for moving said tilter in advance of each opening, as and for the purpose set forth.

2. In a shingle-sawing machine, the combination, with a revolving circular carriage having radial openings, a stationary lip at one end of each opening, a spring-actuated block carrying a lip at the other end of each opening, and a iinger on said block extending beyond the periphery of the carriage, of a shifter-arm on the carriage projecting radially beyond its periphery, a filter frame mounted on a pivot-rod standing at right angles to a radius of said carriage, a shaft journaled below said frame at right an gles to said rod, eccentrics oppositely located upon said shaft beneath the side bars of the frame, a cross-arm keyed on said shaft working in a slot in the frame-work and adapted to be struck by said shifter, and a tripper engaging the fingers on said movable blocks, all as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in J No. M. LEE, J. E. FoXwoRTHY.
