PATENT SHINGLE-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 271,407, dated January 30, 1883. Application led September Q9, 1882. (No model.)

To all whom it may concern:

Be it known that I, WlLLIAM A. BRADLEY, ot' Oshkosh, in the county ot' Vinnebago and State ot' Visconsin, have invented a new and useful Improvement in Shingle-Machines, of which the following is a full, clear, and'exact description.

My invention consists ot' improvements in the driving-gear, also in the bolt-dogging apparatus, and also in the bolt-setting apparatus ot' shingle-sawing machines, as hereinafter fully described.

Reference is to be had to the accompanying which similar letters of reference indicate corresponding' parts in all the figures.

Figure l is a plan view of a shinglemachine constructed according to my invention. Fig.

2 is a side elevation with some of the parts in section. Fig. 3 is a transverse section on the line x x, Fig. l. Fig. 4 is asection ot' the boltcarriage on the line y y, Fig. 3; and Fig. 5 is a section of the settingapparatus, taken on theline z z of Fig. 3.

For the purpose of simplifying the drivinggear and preventing` all slack and lost motion of' the carriage in running and on vthe backstroke, I propose to dispense with toothed wheels altogether and employ a be1t-pulley,a, on thesaw-arbor z', for the first part ofthe rewhich pulley the driving-belt b works onto the large pulley d of the counter-shaft e, which carries a small driver,f, from which the belt g works onto the large pulley h ot' the feed-shaft c. A tightener, kl m, will be used with the belt b for producing the necessary tension to drive the feed-gear, and for slackening the belt to allow the feedvto stop, when required, without stopping the saw-shaft, on the top ot' which the saw jis mounted by the collar It. The main belt runs on the pulley a2 for driving the saw. Y

Only a single machine is shown in thiscase; but by the extension of the frame to the left hand of the main feedshaft, and the duplication thereon ot' the mechanism shown, except shaft c, the machine will bemade double, which is the intention in practice.

The feed-shafts c and e and thc saw-arbor t' are arranged in suitable steps, n, in the bedtimbers ofthe frame; and to operate the boltcarriage 0 for sliding itfor Ward and backward in the guidesp to feed the bolts to the saw, I propose to apply the eccentric q to the upper end of the feed-shaft c to work'the yoke-lever s, fixed on a pivot at t to vibrate so as to reciprocate the carriage by its swinging end n, to which the 4carriage is `connected by a suitable rod, c. This makes a smooth-working device, entirely t'ree from shocks and jars by the backlash of slack gears.

For dogging the bolt I use a sliding dog plate or bar, w, xed in guides x in one end ot' the carriage, with a spring, y, to cause it to grip and hold the bolt, and also with a rod, z, forming a support to the spring, and having a stud, a', by which the dog is automatically detached from the bolt for resetting said bolt by the inclined arm b', along which the stud a is moved bythe carriage in the latter part of its back-stroke, so as to free the bolt from the dog and allow the bolt to fall on the table c', on which it rests and slides until by the forward motion of the carriage the stud a passes oft' from the inclined -arm b', and the spring y again causes the dog-bar to grip the 'end of the bolt. Said bar may have any suitable ar,- rangement ot' spur studs or points to penetrate the block sufficiently to insure a firm hold. Thus the bolts are automatically shifted and set for the successive cuts. The object of locati ng the dog slide guides on the top of the carriageis to place them and the spring and stud so far above Athe saw that they will not be clogged by the sawdust.

In order to cause the resetting of the bolts, so as to alternately cnt butts and points at the respective ends of the bolts, lthe bars c, forming the table whereon the bolts fall and rest in the resetting operation, are mounted on the bars d', pivoted at the center ot the table, at c', to the head f ot' vertical standard g', said bars ranging therefrom toward the respective sides of the machine, and resting, when in their normal position, on the temper-screws h at their outer ends, said temper-screws being tted adjustably in the cross-bar i', supported on the standard g by the collar j. The respective sides of the table thus supported and pivoted may therefore be raised and lowered to tilt the bolt, or, rather, cause it to assume an inclined position when it falls, one end falling lower than the other; and in order to alternately shit't the respective sides ofthe table for alternating the butts and points of the shingles the bars d are formed with inclines 7c on the lower side, and wedges l are mounted on a sliding bar, m', under them, which are shifted each time the carriage goes forward by the zigzag earn-disk n', which works between the studs o on said bnr m, and is worked by the catch-pawl p', pivoted to the carriage so as to engage one of the stud-pins q of the disk each time the carriage goes forward to the saw, and shifts the canrdisk to the extentof one of the inclines ofthe disk, thus reversing' the movement of the slide at each motion of the carriage and alternately lifting the opposite sides ofthe table c. The catch-pawl p is provided with a lever handle, t', by which to lift it up so as to set the pin u under it, and hohl it out of engagement with the disk n when it may be desired to cut the shingles in uniform thickness. The wedges l are slotted for their fastening bolts w', in order that they may be shifted forward and backward along the bar to raise the sides of the table more or less, to vary the thickness of the butts and points of the shingles as may be required. The standard g is Y adjustable by the screw-nuts a," and supporting-bar y to vary the height of the table.

i Having thus described my invention, I claim as new and desire to secure by'Letters Patentl. In a shingle-machine, the combination, with the saw-arbor i, provided with the pulley a., and the feed-shaft c, provided with the pulley h, of the counter-shaft e, provided with the pulleys df, the belts b g, and the belt-tightener It lm, substantially as and for the purpose set forth.

2. In a shingle-machine, the combination, with the boltcarriage 0, of the tablec d', composed of two parts hinged together, and means,

substantially as herein shown and described, i'or alternately raising and -lowering the sides of the table, as set forth.

3. In a shingle-machine, the combination, with the table c d', composed of two parts hinged together and having inclines k' on its under surface, of the shifting bar m', provided with the wedges l', and means, substantially as shown and described, for operating said shifting bar, as set forth.

4. In a shingle-machine, the combination, with the table c d', composed of two parts hinged together and having inclines h on its under surface, of the bar i, the temper-screws h', the shifting bar m,provided with wedges l', and means, substantially as shown and described, for operating said shifting bar, as set forth.

5. In a shingle-machine, the combination, with the adjustable standard g', provided with the head f', of the table c d', composed of two parts hinged together and pivoted at its center tothe said head, and the temper-screws h', substantially as and for the purpose set forth.

6. In a shingle-machine, the combination, with the table c d', composed of two parts hinged together and provided with the inclines lr, of the shitting bar m', provided with the wedges l and the studs o', the zigzag camdisk n', provided with the pinsq,and the pawl p', substantially as and for the purpose set forth. 7. In a shinglemachine, the combination, with the table c d', composed of two parts hinged together and provided with the inclines 7c', the cross-bar t', and adjustable support g','ot the sliding bar m', provided with wedges l', and the zigzag camdisk n', substantially as and for the purpose set forth.
