SHlNGLE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 287,462, dated October 30, 1883.

To all whom it may concern:

Be it known that I, XVILLIs J PERKINS,-Of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Shingle-Sawing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Hy invention relates to an improvement in shingle-sawing machines; and it consists of a series of carriages flexibly connected together and adapted to travel 011 a horizontal endless track above ahorizontally-revolving saw, and mechanism for automatically feeding the shingle-bolts to the saws.

My invention further consists of the parts and combinations of parts, as'will be more fully described, and pointed outinthe claims.

In the accompanying drawings, Figure 1 is a plan view of my improved machine. Fig. 2 is a view in side elevation of the same. Fig. 3 is a plan view with the carriage removed. Fig. 4 is a detached View, showing the manner of connecting the carriages. Fig. 5 is a detached perspective view of the spalt-remover and the levers for operating the same, andFig. 6 is a detached perspective view of one of the carriages.

A represents base of the machine, provided with the upright standards B, which latter support the endless rail 0.

D are transverse bars, the outer ends of which are rigidly secured to the endless rail 0, and form supports for the central plate, E, which latter is provided on its upper face with an endless groove, F, formed concentric with the rail 0. The bars DD, besides supporting the central plate, E, are also provided with bearings, in which the vertical shafts G G of the horizontal saws HH are journaled. These saws are preferably situated on opposite sides of the machine, immediately under the shingle-bolt carriage, and are adapted to cut a shingle from each bolt as the latter passes over the saws.

' The saw-arbor G is provided with a large belt-pulley, w, and a small pulley, 10 which communicates the motion from the saw-arbor to the shaft w throughthe belt 10 This shaft Application filed June 28, 1883. (No model.)

in turn is provided above the pulley Q03 with the pulley 10*, which transmits the motion of the shaft w to the vertical shaft 10 and the latter in turn, through the intervention of the friction-wheels w and w, (which, by the way, can be made of any suitable material,) transmits the motion to the shaft K. The friction- .wheel 20 can be moved on the shaft 10 to engage or disengage it from the wheel 10 as desired.

The shaft K projects through the plate E,

and is provided at its upper end with the small pinion, M, which latter meshes with and drives the larger pinions, NN. These twolast-mentioned pinions are secured to shafts j ournaled in the plate E, and are so situated as to engage the rack-bars on opposite sides of the endless groove and move the carriage to which the said rack-bars are secured. By applying power to the opposite sides and to the carriages traveling in opposite directions, the machine is caused to run much more smoothly, and the danger of binding the parts is entirely obviated.

The rail 0 and the plate E are situated in the same horizontal plane, and form between them an endless trackway, on which the shingle-bolt carriages move. These carriages (eight in the present instance) are connected together side by side by the links Q, the opposite ends of which latter are pivotally connected to the adjacent carriages, and form a flexible connection between the said carriages, for the purpose of enabling them to turn the curves in the trackway.

The number of carriages and saws employed on the machine is dependent on the size and capacity of the machine. Thus, for instance, if the machine is adapted for eight carriages, twosaws would be used, if sixteen carriages are employed four saws would be used, and so on, gradually increasing the number of saws in proportion to the carriages employed. These carriages are made of metal, and each is provided with a head-block, P, and a dog,

P, which latter is moved automatically, as

will be hereinafter described, for the purpose of feeding the bolt downward to the saws.

The head-blocks P are situated, preferably, near the outer end of the carriages, while the dogs 1?, which move in suitable slide-bearings,

ICO

near end to one end of the link 0,

are situated near the inner end of the said carriage. Each of the dogs P is connected at its while the opposite end of the said link is connected to the lower end of the bell-crank lever B. This bell-crank is fulcrumed at its knee to the upright bearing a, and projects inwardly, andis provided at its outer end with a weight, S, the tendency of which is to constantly hold the dog firmly against the bolt. Each carriage is also provided on its inner edge with a rackbar, T, which, when the carriages are united by the links, form an endless drive-chain, which meshes with the pinions before referred to, and are driven thereby. Each carriage is also provided at its opposite inner corners with the anti-friction rollers d, which latter are adapted to travel in the endless groove E, for the purpose of holding the carriages in position and the rack-bars secured to said carriages in engagement with the rack. The outer ends of the carriages run on the outer rail C, and they can, if desired, be provided with rollers or bearings, for the purpose of decreasing the friction between the parts.

U are inclined arms rigidly secured to the central plate, E, in such position as to engage the weighted end of the'bell-crank, and consequently move the dog inwardly away from the shingle-bolt. These arms U are each provided at their front ends with a sharp curve, up which the horizontal arm of the bell-crank rides, until the latter have been sufliciently elevated to retract the dogs, and consequently allow the bolts to drop. The arms then incline downwardly and allow the weight end of the bell-crank to descend,and consequently lock the bolt in position to be engaged by the next saw.

Immediately below and to the outer side of each arm is the table I), on which the bolt falls after it is released by the dog. The bolts are moved along on these tables bytheir respective carriages, and before the end of the table is reached the bolts are firmly locked in position, with their lower faces projecting below the saw a distance sufficient to enable the saw to cut off one shingle. Before the bolt reaches the next saw it is again automatically lowered, and so on until nothing but the spalt remains, which latter is thrown out of the carriage by the upward movement of the rod WV. This rod passes upwardly through the plate E and terminates in an enlarged head, while the lower end thereof is pivotally secured to the inner end ofthe lever X. This is centrally pivotedto the machine-frame, and is pivotally connected to one end of the operating-lever Z, which latter is centrally pivotedto the outside of the machine-frame, withineasy reach of the operator. After the bolt has been reduced to spalt, the carriage containing it is allowed to proceed until the bell-crank connected thereto rests immediately over the enlarged end of the rod W. Just at this instant the operator elevates the free end of the lever Z, whiclnthrough the intervention of the lever X, elevates the rod W. The upper enlarged end of the rod strikes the weighted end of the bell-crank,

which withdraws the dog and releases the spalt and allows it to fall through onto the floor. WVhen the empty carriage reaches the table, another bolt is dropped therein and locked, and the operation is continued.

It is evident that numerous changes in the construction and relative arrangement of the several parts might be resorted to without departing from the'spirit of my invention, and hence I would have it understood that I do not limit myself to the exact construction shown and described, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is- V 1.
