IMPROVEMENT IN SHlNGLE-MACHINES.

The Schedule referred to in these Lettere Patent and making part of the same.

To all 'whom it may concern:

` Be it known that I, JOSEPH JIMO, of Vergennes, in the: county of Addison and State of Vermont, have invented certain .Improvements in Shingle-Machine, of which the following is a specification, reference being had to the accompanying drawing.

My invention relates to that class of shinglemachines in which the bolts or blocks are fed against the saw by a horizontal rotating table; and

The invention consists in an improved manner of constructing and arranging various details, as hereinafter described. l

' Figure l is a top plan view of the machine with certain portions broken away;

Figure 2 is a side elevationV of the same;

1Figure 3 is auend View otL the tilting table and the shaft for operating it; and

Figure 4, an end view of the planer or cutter.

A represents the frame ofthe machine, at thecenter of which is mounted a vertical shaft, B, having on its upper end a large circular horizontal table, O, and' on its lower end a cog-wheel, at.

By the side of shaft B is mounted another vertical shaft, D, provided with cone-pulleys b and a-pinion, c, which gears into wheel a, as shown in figs. l and 2.

In one corner of the frame isV mounted a vertical shaft, E, provided with a large pulley, c, and conel pulleys f, the latter being connected by a crossed belt,

g, with pulleys b, as shown in iig. 2;

At the middle of the frame, near one side, is mounted a vertical shaft, F, provided with three fixed pulleys, h, i, and j, and also on its upper end, above the frame, with a circular saw, G.

The pulley h, which is the smallest of the three, is connected, by a belt, 7:, with the large pulley -e of the corner-shaft E, as shown in lig. 1 and the pulley i is connected, by a belt, l, with a large pulley, m, on a vertical driving-shaft, H, mounted in one corner of the frame, as shown' in iig. l.

The shaft H is also provided with a second pulley, n, through which the power to drive the` machine is applied.

When the shaft H is set in operation motion is transmitted through belt l to the saw-shaft, and thence through belts h and g to the pinion c, which in turn rotates the wheel a and turns the table or hed C.

Owing to the arrangement and proportion of the various parts the saw is revolved at a high and the 1 bed at a slow rate of speed.

Through the bed (l is formed a number of rectangular openings, J, to receive the bolts or blocks of, wood, so that as the. bed revolves the different bolts will be carried in succession over the saw G.

To the bed C, at each opening J, is pivoted a pair of levers, K L, one at each end ofthe opening. The

inner ends of the levers, opposite the openings J, are provided with teeth to engage in and hold the block or bolt ofV wood. y

The two levers are connected by a bar or link, fr, in the manner shown, so that they shall both swing against or away from the block at the same time.

The end of lever K of each pair is extended out beyond the edge ofthe bed C, and an upright, M, is secured to the side ot' the main frame in such manner as to strike against levers K as thebed revolves, and thus open-the different pairs of arms in succession.

A spring, c, is secured behind each arm K, so as to keep the pair closed, except for the instant they are held open in passing standard M.

At one side of frame A, under the bed C, is mounted a tilting bed or table, N, shown in place in ligs. 1 and 2, and detached in Iig. 3.

This table is support-ed at one side on a stationary horizontal shaft, Izo, and at the opposite side it rests on a rotating shaft, x, iiattened on its two sides, so that when the table rests on either of the flat sides of the shaft it stands ,inclined in one direction; but when the shaft is turned up edgewise the bed is inclined in the opposite direction.

To the outer end of shaft :c is secured a toothed wheel, O, and to the outer edge of the bed, close together, are secured three teeth or fingers, y, which, as the bed C revolves, engage with the. wheel O and turn the same, the shaft being turned a quarter of a revolution at each revolution ofthe bed.

During one revolution of the bed C the table N' turn wheel O and tilt the table in the opposite direction. The table-remains iu this latterpositiou until the bed completes the second revolution, when the lingers again come into play and the table is tilted back in the first position, and so on repeatedly.

On the opposite side of the framefrom the saw, under the bed C, is mounted a horizontal shaft, P, provided with cutting or planing-blades, as shown in figs. 1, 2, and 3.

On the outer end of this shaft P is secured a pulley, lt, and to the frame below said pulley aie secured two guide-pulleys, S, as shown.

A belt, T, is passed over the pulley 1t and under the pulleys S, and then crossed and carried around pulley- 7' of shaft F, as shown in gs. l and 2.

The various parts being thus arranged, a bolt clamped in cach of the openings J, and the machine set in motion, the operation is as follows:

As the bed C revolves each bolt is carried around over the rotary cutter P and the underside ofthe bolt smoothed or planed off. The bolt then passes around until it is over the table N, when the lever K strikes standard andlthe levers are opened tir zuifiiistaut so asto let the bolt drop down `and rest on the table N. I

As soon as lever K passes the standard the levers clasp the block and hold it in position while it is carried around yover the saw, which cuts a shingle loft" from the under side. l

The block is then carried around as before, being first planed off', and then released so as to rest on the table; then clamped again, and nally presented Vtothensaw. y Y n The table N is placed below the level of the saw, and serves as a gauge to regulate the thickness of the shingle.

Owing to the arrangement of the Atable N,vwhieh v stands at one inclination during one revolution ofthe bed 0, and at the opposite inclination during the next revolution, the saw outs obliquely through the boltfirst in one direction and then in the other, so that therev is no Waste of material, as the butt of one.shingle is taken o" from the right and the next o" from the left end ofthe bolt. To provide for stopping the motion of the bed without stopping the other parts, the lower end of shaft D is mounted in 'a box, z, arranged to slide laterally,

and a lever, ax, is pivoted 'to the frame and connected at its inner end with the sliding box, and at its outer end with a vertical pivoted hand-lever, S, as shown. By moving the hand-lever the box z and the lower end of shaft D maybe moved so as to throw the pin ion c in and out of gear, and thus the bed'stopped and started when desired.

Having thus described my invention,

What I claim is- 1. lhe tilting table N and the shaft' having the wheel O attached, in combination with the rotating ltable C provided with the fingers '1, all constructed and arranged to operate as' set forth.

2. A shingle-machine, .consisting of the rotating table' G with its dogs K L, the saw G, .the tilting table N, and revolving planer P, all constructed and arranged to operate substantially as herein shown and described.

JOSEPH JIMO.
