SHlNGLE-SAWlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 555,148, dated February 25, 1896. Application filed May 8, 1893. Serial No. 473,392! (No model.)

To all whom it may concern:

Be it known that I, FRANK CHALLONER, of Oshkosh, in the county of innebago and State of \Visconsimhave invented certain new and useful Improvements in Spalt-Droppers for Shingle-Sawin g Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to that class of shinglesawing machines in which the shingle bolts or blocks are held and moved horizontally in a rotary carriage over one or more horizontal saws located below the carriage. Its main objects are to facilitate the dropping or discharge from the machine of the spalts or residuum of the shingle bolts or blocks, and in the attainment of that end to employ fluid-pressure for the operation of the spaltdropper, and to arrange the trip mechanism for controlling the operation of the spaltdropper for the several block-receptacles in the carriage within constant reach of the operator.

It consists of certain peculiarities in the construction and arrangement of the component parts of the machine hereinafter particularly described and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a plan view of a rotary shinglesawing machine to which my improvements are applied. 2 is an enlarged front ele vation and partial vertical section on the line 2 2, Fig. 1, of the spalt-dropper. Fig. 3 is a side elevation and partial vertical section of the same on the line 3 3, Fig. 1. Fig. 4: is a medial longitudinal section of the cylinder and its associated valve-case on a still larger scale; and Figs. 5 to 8, inclusive, are detail views, on an enlarged scale, of the trip mechanism by which the operation of the spaltdropper is controlled, Fig. 5 being a front elevation, Fig. 6 a side elevation, and Fig. 7 a horizontal section on the line 7 7, Fig. 5.

Referring to Fig. 1, A represents a portion of the horizontal rotary carriage, which is supported upon the upper end of a central vertical shaft 0, and is formed with a series of block receptacles or openings a a, provided in the usual manner with dogs (not shown) for holding the shingle-blocks therein.

B B are two horizontal saws fixed to the upper ends of vertical arbors located just below the carriage on opposite sides of the machine.

C is a spider supported upon the upper ends of columns 0 and c from a base 0 and constituting therewith the frame of the machine.

D D are the tilt-tables located adjacent to the cutting-edges of the saws a little below the plane thereof and arranged to give the proper inclination to the shingle-blocks as they are dropped thereon to cause the butts and points of the shingles to be taken alternately from opposite ends of said blocks.

E and E are curved horizontal ways concentric with the carriage and supported approximately in the plane of the saws between said saws and the tilttables.

F is a vertical carriage-driving shaft,which is geared in the usual manner (not shown) with the carriage and with a horizontal pulley-shaft G.

The foregoing parts are shown and described for the purpose of explaining more clearly the construction and operation of my improvements, but in themselves constitute no essential part of my invention, and may be of any construction or arrangement suitable for use in connection with such improvements.

The curved way E on the front side of the machine next to the operator is formed with an opening of sufficient length to permit the passage of a shingle block or spalt of the greatest width the machine is designed to receive. It is provided with and normally closed by a plate or slide 11, which constitutes a continuation thereof, and is movable horizontally in a radial direction upon ways h 71, adj ustably attached to and supported by the spider C, as shown in Fig. 2. It is connected by links 1' v with arms 2" c" on a horizontal rock-shaft I, by which both ends are caused to move together and are prevented from binding in their ways.

J is a cylinder preferably arranged in a horizontal position in which it may be conveniently supported upon the spider C, as shown. It is provided with apistonj, which is connected by the piston-rod j with a bracket attached to the under side of the slide H. The cylinder is formed or provided on one side with a cylindrical valve-case K, in which is fitted a piston-valve having two heads in 10, mounted upon a rod k. The valve-chamber and cylinder are connected near their ends by passages j 2 j as shown in Fig. 4, which have branches j j opening into cavities next to or near the cylinder-heads. The ends of the branches j 3 opening into the cylinder are norm ally closed by inwardly-opening valves j j The valvecase is also formed with exhaustopenings 73 7& near its ends and an intermediate supply or inlet opening which is connected by a pipe 7; with the compressed-air reservoir 0 or other source of fluid-pressure. It will be observed that one of the hollow supporting posts or columns 0 of the frame is utilized in this case for the compressed-air or fluidpressure reservoir.

Referring to Figs. 5 to 8, inclusive, in connection with Fig. 1, L is a trip-wheel mounted next to the operators table or within easy reach of the place usually occupied by the operator upon the front end of a horizontal shaft Z, which extends across the machine and is provided at its rear end with a worm-wheel Z, meshing with a worm f on the carriagedriving shaft F, through which connections said trip-wheel is rotated isochronously with the carriage. The trip-wheel is provided with a series of radial ly-m ovable trip-pins Z Z corresponding in number and arrangement with the number and arrangement of the blockreceptacles in carriage A. These pins are held in place either in normal or abnormal position in which they may be left by the operator or by the restoringdncline by springs F.

m m are inclines formed on bars M M, which are pivoted at one end to fixed arms projecting on opposite sides of a sleeve N, and are connected at the opposite end by links m m with a cross-head n on a rock-shaft n passing loosely through said sleeve and provided at its opposite end with an arm n .v The incline m is located outside of the rim of the trip-wheel L in or adjacent to the path of the outer ends of the trip-pins Z Z when they are projected outwardly in normal position, and the incline m is located between the rim and center of said wheel in or adjacent to the path of the inner ends of said trip-pins when they are projected inwardly into abnormal position. The arm 12 is connected by a rod 02 with one arm of a bell-crank lever O, the other arm of which is connected with the valve-rod It, as shown in Figs. 1, 2, and 3. s

P is a fixed incline located in the path of the inner ends of the trip-pins Z- and arranged to automatically return them into normal position after they have acted upon the incline m to open the spalt-dropper.

My improved machine operates as follows: The reservoir 0 being supplied with compressed air or any other suitable fluid medium under pressure, while the trip-pins Z Z are all projected outwardly, as shown in Fig. 5, the valve L a will be held in the position in which it is shown in Fig. 1, thereby admitting the actuating medium into the inner end of cylinder J and holding the piston j and the slide H with which it is connected in normal position, closing the opening in the curved way'E. \Vhen the operator wishes to drop a spalt from any of the block-receptacles a a in the carriage, he thrusts the corresponding trip-pin Z inwardly at any time in its passage from the fixed incline P to a point adjacent to the incline m. The inner end of said trippin being thus projected into the path of said incline m and held in place by the contiguous spring Z engages and moves said incline inwardly, turns the cross-head n with which it is connected into the position in which it is shown in Figs. 6 and 7, and thereby shifts the valve 70 it through the connections hereinbefore described into the position in which it is shown in Fig. at. The actuating medium. is now admitted from the valve chamber through the passage j and branch j at the outer end of the cylinder, between the piston j and outer cylinder-head, and the passage j at the other end of the cylinder is opened to exhaust through the'opening k at the inner end of the valve-case. The piston is thereby instantly moved inwardly, carrying the slide H with it and presenting an opening underneath the receptacle from which the spalt is to be discharged. The piston j is cushioned at the end of its stroke in both directions by the air or fluid medium contained in the ends of the cylinder between the openings of passages 7" j thereinto and the cylinder-heads, the valves ff closing the intermediate ports of the branches j" j, except for the admission into the cylinder of the actuating medium. Upon clearing the incline m the trip-pin Z which has just shifted the spalt-dropper, encounters the incline P and is thrust outwardly thereby into its normal position. The next succeeding trip-pin, which is in normal position, engages the incline m and turns the crosshead it back into the position in which it is shown in Fig. 1, restoring the valve, piston and slide H to their normal positions.

It is obvious that spalts may be discharged from any number of block-receptacles in successsion by pushing in the corresponding trip-pins Z 1*. It will also be observed that the trip-pins being at all times within reach of the operator may be set to operate the spalt-dropper at any point in their passage, whatever may be the position of the blockreceptacle in the carriage from which the spalt is to be discharged. This will be found a great convenience and advantage over the arrangement heretofore employed, in which the trips were applied to the carriage, one
