SPALT-DROPPER FOR ROTARY SHINGLE-SAWING MACHINES.

SPECIFICATION forming part of Letters Patent No. 559,362, dated May 5, 1896.

Application filed December 26, 1893. Serial No. 494,648. (No model.)

T0 otZZ whom it may concern.-

Be it known that I, FRANK GHALLONER, of Oshkosh, in the county of Winnebago and State of Wisconsimhave invented certain new and useful Improvements in Spalt-Droppers for Rotary Shingle-Sawing 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 being had 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 shingle -sawing machines in which the shingle blocks or bolts are carried in a rotary carriage over one or more horizontal saws located below the carriage. Its main object is to facilitate discharging from the machine shingle-blocks or the residuum commonly called spalts.

It consists of certain novel features in the construction and arrangement of the component parts of the spalt-dropping mechanism, hereinafter particularly described, and point ed out in the claims.

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

Figure 1 is a plan view of a rotary shinglesawing machine embodying my improvements. Fig. 2 is a vertical section on the line 2 2, Fig. 1, showing the spalt-dropping mechanism, on an enlarged scale, in side elevation; and Fig. 3 is a front elevation of the spaltdropper.

A designates the rotary carriage, provided in the usual manner with a number of block openings or receptacles a a and mounted upon the upper end of a vertical shaft B, which is supported by and provided with suitable bearings in the frame.

0 O are the saws, mounted upon the upper ends of vertical arbors and located, in the usual manner in this class of machines, on diametrically opposite sides of the carriageshaft B and a short distance below the carriage.

D D are tilt-tables located on the approaching side of the block-receptacles to each saw and normally set so as to cause the saws to cut the butts and points of shingles alternately from opposite ends of each block. They are constructed and arranged in the usual manner to be reversed as to their ineli nation at the will of the operator, for the purpose of taking two or more butts in succession from the same end of a shingle-block, and thus making the cuts approximately parallel with the grain of the blocks.

The foregoing parts are common to rotary shingle-sawing machines of this class, and I make no claim to invention therein.

E E represent curved block supporting ways located directly below the block-receptacles of the carriage between the saws and tilt-tables on opposite sides of the machine, with their upper surfaces in approximately the same plane with the saws. The shingleblocks after clearing the saws are dropped thereon and carried upon the tilt-tables in advance. The way E, on the front side of the machine, has an opening which is normally closed by a laterally-movable plate or sectionF, for the purpose of discharging a block or spalt from the carriage when desired. This plate or section is supported by arms or braces f f, extending laterally from a vertical shaft G, located near the path of the shingleblocks in the machine, so that when it is turned the plate or section F will be moved laterally out of or into the opening in the way The plate or section F is made of sufficient width to afford the required-support for the shingle-blocks when it is in its normal position, and to prevent them from being displaced in or discharged from the carriage, except when desired.

H is a trip-wheel fixed upon the carriageshaft B below the carriage and provided with two sets of trips h h and h h, the former fixed and projecting at intervals from the periphery of said wheel and the latter movable radially in the rim of said wheel and being located below and alternating with the fixed trips h h. The movable trips h h are withdrawn and stand normally within the periphery of the trip-wheel.

I is a bell-crank lever fulcrumed at its angle to the frame of the machine adjacent to the periphery of the trip-wheel and carrying at the extremity of its shorter horizontal arm a friction-wheel i, which projects normally into the path of the movable trips h when they are projected from the trip-wheel. The longer vertical arm of said lever is connected by a link J with the upper supporting arm or brace f of the movable section or plate F.

K is a lever fulcrumed to the base of the machine and formed or provided at its inn er end with horizontally and vertically disposed inclines 7t and 7c,the first of which is arranged when elevated to engage the inner end of the next movable trip-pin h and move the same outward through the periphery of the tripwheel. The other vertical incline 7c is constructed and arranged when elevated to be engaged by the next succeeding trip-pin h in normal position and to be thereby depressed, thus restoring the lever K to its normal position. To the outer or front end of the lever K is pivoted a vertical rod or bar L, extendin g upwardly therefrom to a point within easy reach of the operator.

M is a fixed incline located adjacent to the periphery of the trip-wheel in position to thrust the movable trip-pins 71/ inward into normal position after they have operated upon the roller 2'.

In Fig. 2 the lever K is shown in abnormal position for thrusting a trip-pin h outwardly.

My improved spalt-dropper operates as follows: When it is desired to drop a block or spalt from the carriage as the receptacle in which it is contained passes the operators stand, he depresses the rod L, elevating the inner end of lever K and carrying the incline into the path of the movable trips h h, which project normally inside of the rim of the trip-wheel II. The next trip-pin which is properly located to discharge the desired block or spalt is thereby thrust outwardly beyond the periphery of the trip-wheel, and the next succeeding trip-pin h, engaging the illcline 7o, depresses the inner end of lever K and restores it to normal position. lrVhen the block or spalt to be dropped arrives over the movable section or plate F, the projected pin h engages the under side of roller 2', forces it upward, swings the upper end of lever I inward, and carries the movable section or plate F out ofthe opening in the curved way E, through which the block or spalt can now freely fall. The block or spalt being thus dropped, the plate F is returned to normal position, closing the opening in the fixed way by the next fixed trip h engaging the upper side of the roller 1'. The pin h which has just acted on said roller, engaging the incline M, is restored thereby to normal position.

In the manner above explained, blocks or spalts may be dropped from anyone or more receptacles of the carriage at intervals or in succession.

Various changes in minor details may be made within the intended scope of my invention.

I claim- 1. In a shinglesawing machine the combination with a rotary carriage provided with a series of block-receptacles,of a block-supporting way located below said receptacles and having an opening therein, a laterally-movable section of sufficient width to support a shingle-block thereon, adapted to normally close said opening, a vertical shaft located at a distance from the opening in said block-supporting way adjacent to the path of the blockreceptacles of the carriage and provided with laterally projecting arms or braces which carry said movable section, mechanism for turning said movable section horizontally on said vertical supporting-shaft from and into normal position in the opening in said way, and a series of trips corresponding in number and position with the block-receptacles in said carriage and movable synchronously therewith and also movable by the operator into abnormal position to operate said mechanism, substantially as and for the purposes set forth.

2.
