marked thereon, forming part of this specification.

My invention relates to lumber conveyers and separators for horizontal sawing machines, whereby a board and slab are automatically separated and conveyed away to their proper depositories.

As now usually operated the board and slab passes from the horizontal saw-table to and upon a train of receiving rolls, lo cated at the delivery end of said saw-table, from where the slab is manually lifted from the board and carried to its depository, and the board manually removed from the receiving rolls and carried to its depository,

the process usually requiring the work of two men.

The object of my invention is to provide mechanism which operates to remove the board and superimposed slab from the receiving rolls, remove the slab from off the board and automatically convey each in the proper direction to the designated depositories therefor. v

The features of this invention are hereinafter fully set forth and explained, and illustrated in the accompanying drawings, in which Figure 1, is a top or plan view of my im proved lumber conveyer and separator, showing it relatively to the delivery end of a saw-table. Fig. 2, is a vertical section of the same on the line era-em in Fig. 1.

In these drawings, A, indicates the delivery end of a saw-table of a horizontal sawin machine; B, indicates the mill floor, and O O and C, indicate the parts of the machine frame. Mounted in the part, C, of the frame in line with the "delivery end, A, of the saw-table, there are a series of receiving rolls, D, upon which the sawed material passes fromthe saw-table, A.

In bearings, e, on one side of the part, C,

of the machine frame there is mounted a rock-shaft, E, and on said rock-shaft there are mounted, intermediate of the rolls, D, a series of arms, E carrying pulleys, e ,preferably of the sprocket type, and on said shaft, E, there is also mounted a downwardly projecting arm, E, for the purpose hereinafter set forth. ,On the frame, C, at the opposite ends of therolls, D, I also mount a shaft, F, provided at one end with a driving pulley, Fflcomrniinicating with a source of power hereinafter described, and

at intermediate points with pulleys, f, preferably sprockets, and on the pulleys, c and f, I place belts, preferably sprocket-chains, 7. On the side of the part, C, of the .ma} chine frame somewhat belowand at one side of the shaft, F, I mount a shaft, G, pro

'vided with triangular frames, G G and G which are so secured on said shaft as to be rotatable thereby, and in the central one of these frames I provide studs, g, on one side thereof adapted to be engaged by mechanism hereinafter described, for rotating the shaft, G, and the triangular frames, G G and Gr thereon, and at each corner of these triangular frames there is a shoulder, 9 which projects sufficiently above the faces thereof to engage the edge of a board resting thereon, as illustrated in Fig. 2. These shoulders also operate as stops to engage spring latches, 9 secured to the frame, C, which limits each rotative' movement of said triangular frames.

On the frame, C, there is mounted a bellcrank lever, H, one arm, h, of which extends to and is adapted to be engaged by the studs, g", which project from one side of the triangular frame, G and the other arm, 72 of said bell-crank lever is pivoted to a link, E the opposite end of which link is pivoted to the arm, E as is clearly shown in Fig. 2. Preferably below the mill floor, B, and under the central triangular frame,

B an upright cylinder, I, provided with a piston, (not shown), connected to a pistonrod, I and pivoted to the upper end of said piston-rod, I, there is a rod, K, which extends upward and is adapted to engage one of the studs, 9, on the central frame, G so that when the piston-rod, I moves upward the triangular frame, G and the like frames, G and G on the shaft, G, will be rotated one third of a revolution, and

until th houlders thereon engage with G I mount on a suitable supporting frame,

the stops, 9 as illustrated in Fig. 2, and during this movement of the frame, G the stud, g thereon engages the arm, 72., of the bell-crank lever, H, and raises it, which, through the arm, 5, thereof, link, E and arms, E and E raises the pulleys, e so that the belts, f raise the sawed board and slab ofl? of the rolls, D, and convey them laterally to and upon one of the faces of the trlangular frames, G G and G where they slide downward until the board engagesthe shoulders, 9 thereon,'while the slab passes over it, as illustrated by dotted lines in Fig. 2. The cylinder, I, is provided with compressed air or steam pipes, 2', leading from the upper and lower ends of said cylinder to a three-way valve, I communicating with a suitable air or steam supply, (not shown) by means whereof the piston in the cylinder, I, is moved up or down as desired. In order to retain the jaw is, on the upper end of the rod, K, in proper alinement so that it will engage one of the studs, 9, at each upward movement thereof, I provide a cord, L, secured thereto and passing under and over suitable pulleys, Z and Z to the end of which cord a weight, L (shown in dotted lines) is secured.

Mounted on the part of the frame, 0 there are a series of conveyer rolls, M, provided with pulleys, M preferably sprockets, over which belts or sprocket-chains, m, operate to drive said rolls in unison, and one of these rolls is provided with a driving pulley, M communicatin with a source of power hereinafter described. These conveyer rolls, M, receive a board from the triangular frames, G G and G at each partial revolution thereof, as shown by dotted lines in Fig. 2.

Secured above the rolls, M, there are inclined guides, N, the upper ends of which aline with the tops of the shoulders, 9 on the frames, G G G when said frames are at rest as illustrated in Fig. 2, .and form a passage-way for the slabs as they slide off of the boards retained on said frames by the shoulders, 9 At the lower ends of said guides, N, are mounted pulleys, O, and on the part C of the mill frame, are upwardly inclined guides or skids, N at the upper end of which on a shaft, P, there are mounted pulleys, P in alinement with the pulleys, O, and guides, N and carrier belts or sprocket-chains, O operate over the pulleys, O, and P and are supported by the guides, N carry the slabs from the bottoms of the guides, N, laterally over the pulleys, P The shaft, P, is also provided at one end with a driving pulley, P communicating with a source of power hereinafter referred to.

On the part, C of the mill frame there is mounted a series of conveyer rolls, Q, provided with pulleys, Q over which a suitable driving belt or sprocket-chain, q, op-

I mount a driving shaft, R, preferably below.

the mill floor, B, communicating by a belt, R with a suitable motive power, and upon this shaft, B, there is a pulley, R communicating by means of a belt, S, with the pulley, F on the shaft, F; a pul1ey, R communicating by means of a belt, S with the pulley, M for driving the rolls, M; a pulley, R communicating by means of a belt, S with the pulley, P, on the shaft, P, operating the conveyers, O and a pulley, R communicating by a cross-belt, S with the pulley, O driving thetrain of rolls, Q, so that all of these mechanisms are operated thereby in unison.

In operation as the sawed board with the slab superimposed thereon has passed oif of the saw-table, A, and upon the receiving rolls, D, the operator moves the valve, P,

which admits air or steam into the lower part of the cylinder, I, the piston-rod, I and the rod, K, engaging one of the studs, g, on the triangular frame, G then moves upward and rotates the frames, G G G onethird of a revolution, and simultaneously therewith'the arm, h, of the bell-crank lever, H, is raised actuating the shaft, E, to raise the pulleys, e and the conveyer belts, 7, to raise the board and slab off of the receiving rolls D, and convey them laterally over the pulleys, f, where they fall on one of the inclined faces of the triangular frames, G G ,G on which. they slide downward until the edge of the board engages the stops, 9*, thereon and is retained thereby, while the slab slides off upon the guides, N, and down to the laterally operating conveyer mechanism, O and is thereby conveyed over the pulleys, P and sliding down on the guides, p, is deposited upon the train of conveyer rolls, Q, by means whereof it is conveyed away. Meanwhile as the rotative movement of the frames, G G G is being completed, the bell-crank lever, H, and the conveyer mechanism, 6 f have returned to their normal position, so that the rolls, D,

are ready to receive other sawed material from the saw-table, A, and by a reversal of the air or steam in the cylinder, I, the rod, K, has been moved downward ready to again act to turn the triangular frames, G G G which when done operates as before described, and also drops a board resting thereon upon the conveyer rolls, M, by which it is conveyed away. i

It will be observed that aside from the ap-. plication of the air or steam to the cylinder, I, all of the operations of separating and conveying the sawed lumber and slabs to their proper depositories, are automatically performed without manual labor being necessary therefor. It will also be observed that under some conditions the laterally operating slab conveying mechanism, 0, O and P may be dispensed with, and the conveyer rolls, Q, so located as to receive the slabs directly from the inclined guides, N if desired.

Having thus described the construction and operation of my invention so as to enable others to construct and operate the same, what I claim as new and desire to secure by Letters-Patent is:

1. The combination in a lumber conveyer and separator, of rolls adapted to receive lumber from a sawing machine, rotative separator mechanism, laterally operative conveyer mechanism, mechanism adapted to continuously drive said conveyer mechanism, and a motor mechanism adapted to rotate said separator mechanism and to cause said conveyer mechanism to engage lumber on said receiving rolls when desired, substantially as set forth.
