I aIZZ. who'nt it may concern.-

Be it known that I, PATRICK OOoNNoR, of Tallman, in the county of Mason and State of Michigan, have invented certain new and useful Improvements in Rotary Shingle-Machine s,

- same, taken through the broken line :0 w w m,

Fig. 2. Fig. 4, Sheet 4, is a side elevation of the same, part being broken away. Fig. 5,

Sheet 4, is a sectional elevation of one of. the tables and its support. Fig. 6, Sheet 4, is a side elevation of one ofthe arm-holding pins. Fig. 7, Sheet 4,.is a side elevation of one of the hingedbars, and showing a part of a narrow dog; Fig. 8, Sheet 4, is a sectional elevation of one of the dogs, and showing a part of the rotary frame.

' The object of this invention is to facilitate the sawing of shingles and promote accuracy in such sawing.

The invention consists in a shingle-machine constructed with a stationary frame and a rotary annular frame, divided intocompartments by stationary and hinged bars, and provided with stationary dogs and with movable dogs operated by spring-pressed jointed bars and cam-guides, and tilting tables and their adj usting mechanism, and with a driving mechanism, as will be hereinafter fully described. 7

A is the base-frame of the machine, to which are attached the lower ends of a number of posts, B.

To the upper ends of the posts Bis attached a horizontal frame, 0.

In bearings in the center of the frame 0 revolves a vertical shaft, D, the lower end of which revolves in a step placed in a socket, E,

and centered by set-screws F, passingin through the sides of the said socket and resting against the sides of the said step.

To the upper end of the shaft D is keyed or otherwise rigidly attached the center of I an squarely against the saws.

from which the shingles'are to be sawed. I The bars of the annular frame Hincline'forward. as shown in Fig. 1, so as to carry the blocks Two or more of the compartments of the annular frame H are made large, and are provided with three bars, H,

hinged at their inner ends to the inner rim of the said frame. The outerends of the bars H shut down into grooves in the inner side of the outer rim of the frame H. Withlthis construction, by raising the central bar H, as shown at the right-hand side of .Fig. 1, three compartments will be formed to receive three small shingle-blocks, andby raising the two side bars H, two compartments will be formed to receive larger shingle-blocks.

The shingles are cut from the lower sides of the blocks by the circular saws I, which are secured at their centers by three bolts, J to the upper ends of the vertical shafts K. The upperv parts of the shafts K revolve in bearings I1, secured by set-screws Min recesses in the frame 0, andt-heir lower ends revolve in steps N, placed. in sockets O, and secured in place by set-screws P, so that the shafts K can be readily centered. The saws Iare both driven by the same belt Q, which passes around small pulleysR, attached to the shafts K, and around a large guide-pulley, S, attached to the shaft T, which revolves in bearings attached to the top and base frames, (J A, and is placed midway between and at a littlejdistance in front of the shafts K, so as to give the belt Q a'suf- 'ficient bearing upon the pulley R S to prevent the said belt from slipping. The belt Q passes around guide-pulleys U, pivoted to brackets V, "attached to the floor or other suitable support, and passes thence to and around a,pulley, W, attached to a counter-shafalX, which is driven by-a belt, Y, and pulley Z, or other suitable means, from any convenient power. The drivebelt Q is thus driven by a shaft below the floor and in a horizontal position by the aid of idl'ers on the floor, the said belt imaking a quarter-twist to and from the machine. l W

To the shaft T, below the large pulley S, is

I attached a small pulley, (1, around which passes a belt, I). The belt I) also passes around a large pulley, 0, attached to the shaft (1!, which revolves in bearings connected with the frames 0 A, and to which is attached a small gearwheel, a. The teeth of the gear-wheel a mesh into the teeth of a large gear-wheel, f, attached to the central shaft, D, that carries the annular frame H, so that the said frame will be driven from the shaft T. The belt I) is made taut by a roller, pivoted to an arm of the elbowlever h, which is pivoted at its angle to a bracket, 6, attached to the frame A or other support.

To the end of the outer arm of ,the elbowlever h is attached the end of a cord, j, which passes around a pulley, k, pivoted to a post, B, or other suitable support. To the other end of the cordj is attached a weight, I, of such a gravity as to press the roller 9 against the belt I) with force sufficient to give the requisite tautness to the belt I).

With the end of the outer arm of the elbowlever h is connected the end of a rod, m, the other end of which is connected with the end of a short arm, 12, formed upon or rigidly attached to the vertical shaft 0. The shaft 0 is pivoted in hearings in the frames A C, and upon it is formed, or to it is rigidly attached a long arm, 1), the shaft 0 and arms it thus serving as a lever for withdrawing the tensionroller 1 from the belt I) when it is desired to stop the movement of the annular frame H without stopping the saws.

To three or more of the posts 13 are attached U-shaped brackets q, the outer ends of which are perforated to receive the pins r.

Upon the pins 1', between the arms of the brackets q, are placed spiral springs s, the lower ends of which rest upon the lower arms of the brackets q.

Upon the upper ends of the springs 8 rest collars t, formed upon or attached to the pins 1, below the upper arms of the said brackets. The upper ends of the pins 1' are forked, and to them are pivoted small rollers 10, which bear against the lower side of the rim of the annular frame H. By this construction the central shaft, D, will be relieved from a part of the weight of the annular frame H, and the said frame will be held in a horizontal position. \Vith this construction, should sawdust or other substance get upon the surface of the rollers 14 the springs s will yield and thus prevent the circular frame H from being tilted and the shingles from being cut untrue.

The shingleblocks while passing from one saw toward the other rest and slide upon the curved bars or rails 22 attached to the frame 0, beneath the annular frame H, and extending from the rear side of each saw I, nearly to the forward side of the other saw. The shingleblocks while passing from the rails e to the saws I rest and slide upon the top bars 'of the tables w, which are curved to correspond with and serve as a continuation of the rails 12. The center of each table is formed upon or rigidly attached to the upper end of a standard, :0, the lower end of which rests upon the end of the short arm of an elbow-lever, 3/, so that the lower end of the said standard can be moved in and out radially to tilt the table 10. The upper part of the standard 00 passes through an opening in a bar of the frame 0 and through a slot in a bearing block, z, placed upon the said slotted bar of the frame 0, the said slot being so formed as to allow the lower end of the standard .70 to be moved radially, and to serve as a fulcrum to the said standard in its movements. The bearing- 'block 2 is secured in place by set-screws l,

which pass in through screw-holes in lugs2 attached to the bar of the frame C, so that the said block can be adjusted and trued by means of the said set-screw 1. The center bar of the table 10 is recessed in the center of its upper side to receive the arm 3, which passes through a hole in the forward bar of the said table 10, and its projecting part is so formed that its upper surface will be flush with the upper surface of the table 11:. The arm 3 is designed to support the shingleblock as it is passing from the table to the saw, as the dogs hereinafter described do not grasp the said block till it is about coming in contact with the saw. The arm, 3 is held from longitudinal movement in the table 14; by collars 29, attached to the said arm upon the opposite sides of the center bar of the said table 10, and the said arm is heldfrom turning when the table w is tilted by eye-pins 30, the eyes of which are made triangular to fit upon atriangular-shaped part of the said arm, and the shanks of which enter holes in the bearingblock 2, as shown in Fig. 5. The eye-pins move up and down in the holes in the bearing block 2 as the table 10 is raised and lowered and at the same time fit the said holes so accurately as to hold the table 10 steady. The lower end of the standard :0 is recessed to receive the end of the lever 1, and the upper end of the said lever is recessed to receive the lower end of the said standard, so that the standard will be keptin place upon the lever. The bottom of the recess in the lower end of the standard as is straight, and the bottom of therecess in the upper end of the lever 1 is curved upon the arc of a circle having its center at the pivot of the said lever, so that the table 10 can be tilted without having its height varied. The movement of the lower end of the standard at is limited, and regulated by two set-screws, 4, one of which passes in through a screw-hole in the post B, and the other passes in through a screw-hole in an upright, 5, connected at its upper end with the said post B, and at its lower end with the base-frame A. The lever y is pivoted at its angle to the slotted head of a screw, 6, which screwsinto a foot, 7. The lower end of the foot 7 is rounded, and rests in a recess in the base-frame A, or in a support attached to the said base-frame. The upper part of the foot 8 is squared, to adapt it to be grasped by a wrench, so that the height of the table can be regulated to give the desired thickness to the shingles by turning the said foot on and off the screw 6. The foot 7 is kept from turning upon the screw 6 by a j am-nut, 8, placed upon the said screw, and turned down against the said foot. 1

To the pin that pivots the lever 3 to the screw 6 is pivoted the forked end of a bar, 9, which passes through a guide-slot in the upright 5, and to its outer endis pivoted the slotted upper end of a screw-bolt, 10, the

lower end of which is passed through an eye in the outer end of the bolt 11 where it is secured in place adjustablyby nuts screwed upon it above and below the said bolt 11. The bolt 11 passes through the upright 5, and has nuts screwed upon it upon the opposite sides of the said upright 5. By this construction,

by adjusting the bolts 10 11, in connection with the set-screws 4, the movement of the table 11) can be regulated to give any desired taper to the shingles.

AS shown in the drawings, the table '10 next the sawyer, which is the right-hand table in Fig. 2, is set to cause the butts of the shingles to be cut from the inner ends of the shingleblocks resting upon it, and the other, which is the left-hand table in Fig. 2, is shown as set to cut the butts 0f the shingles from the outer ends of the'said shingle-blocks, as indicated by the heavy dotted lines in Fig. 2, the righthand table being held in position by a Weight, 12, suspended from the outer end of the lever 1 and the left-hand table being held in position by a spring, hereinafter described.

With the outer part of the lower arm of the Y left-hand lever y is connected the upper arm of one of two elbow-levers, 13, which levers 13 are pivoted at their angles to the, posts B or other suitable supports. The lower armsof the two levers 13 are connected by a rod, 14, so that the'said two levers 13 will always move together.

\Vith the outer arms of the elbow-levers y are connected the lower ends of the upright of the said sections of sufficient width to allow the rfollers 16 to pass through. The bar 15 at the right hand side of the machine, on the side at which the sawyer stands, is held down, so

that its roller 16 will be below the flange 17 by the weight 12 connected with the lever y .of

the, said bar 15, and the other bar 15' is held up, so that its roller 16 will be above the flange 17, by a spring, 18, connectedwith the lastmentioned bar 15 and with the post B or frame 0. To supports 19 19, attached to the baseframe A or other suitable supports, are pivoted foot-levers 20 20, with their forwardends be-,

standard it and tilt the table w, so that the next shingle will be out with its butt in a reversed position. When the roller 16 comes to the next opening in the flange 17 it is made to pass through the said opening by the pressure of the weight 12 or spring 18, and the machine continues its work as before. This construe tion enables the sawyer to true and grain the blocks or timber should the said blocks be cut down upon one end faster than upon the other.

To the lower side of therim of the annular frame H, o posite each compartment of the said frame, is attached a stationary dog, 21, to engage with the outer end of the shingle-block,

and in connection with the movable dog 22 hold the said block while being sawed. The dogs 22 slide in dovetailed grooves in the lower side of the inner rim of the annular frame H, or upon plates secured to the lower side of the said inner rim.

To the inner part of each dog 22 is hinged,

the outer end' of a bar, 23, the inner end of which is hinged to a plate, 24, keyed or otherwise secured to the shaft D. The bars 28 have hinged joints in their ccnters,-so that the dogs 22 can be drawn inward to releasethe shingle-.

blocks by raising the middle parts of the said jointed bars. This is done by the cam plates or bars 25, the lower edges of which are secured to the frame 0.

The upper edges of the cam-plates 25 are so formed as to withdraw the dogs 22 as soon as the shingle-blocks have passed the saws, and allow the said blocks to drop upon and slide along therailn, and to allow the said dogs to be forced outward to hold the shingleeblocks with the saws 1., 7 The jointed middle parts of the bars 23 are forced downward to force the dogs 22 outward by spiral or other springs, 26, interposed be-,

tween the said bars and the circular plate 27, keyed or otherwise-secured to the shaft D.

as the said blocks are about tocome in contact The spiral springs 26 are kept in place by guide-pins 28, attached to the bars 23, and

passing through the springs 26 and plate 27.

v The hinge-joints ofthe bars 23 are socon- LII str'ucted as to prevent them from being clogged by sawdust.

The inner ends of the central. hinged bars II project so low as to rest against and hold back the small movable dogs 22, as the said small dogs are required to act only when the said central bars are raised.

The parts of the saws I that project beyond the rim of the annular frame II are covered by shields 31, the ends of which are attached to the frame C, or to supports attached to the said frame, to prevent persons and things from coming in contact with and being injured by the said saws.
