UNITED STATES PATENT OEETCE.
JAMES E. YOUNG, OF AUGUSTA, MAINE.
IMPROVED METHOD OF MANUFACTURING SHINGLES.
Specification forming part of Letters Patent N o. 18,222, dated September 15, 1857.
T0 all whom t may concern:
Be it known that I, JAMES E. YOUNG, of Augusta, in the conn ty of Kennebec and State of Maine, have invented certain Improvements in Shingle-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a plan; Fig. 2, a longitudinal elevation; Fig. 3, an end view. y
To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried out the saine.
In the drawings, A is the bed-frame of the machine, attached to which on one side is the frame B. In suitable bearings on top of this frame runs the shaft O, which carries the circular saw D. A pulley on this shaft com,
municates motion by the belt E to the shaft F, which extends across and has bearings in the bed of the machine. The shaft F carries two loose pulleys a b, which are alternately clutched to and unclutched from the shaft by the bell-crank G, which is pivoted at c to a cross-piece of the bed-frame A. The forked end of the lever G embraces the rims e on the pulleys a h and slides them together on the shaft F. The longer arm of the crank G extends through a slot d in the side of the frame A, and is moved back and forth by the tumbling-bob I-I, attached to the side of the frame A.
O11 suitable ways e, running lengthwise on the frame A, runs the carriage I, which is moved back and forth on its ways by the cords f, attached to each end of the carriage, and wound one round the pulley a and the other in the opposite direction round the pulley h. Thus as each pulley is clutched with the shaft F it winds up its cordf and pulls along the carriage. The other pulley, being at the same time unclutched,allows its cord to unwind. To the front of the carriage I are attached adjustable stops g h, by which the tumbling-bob H is tripped the instant before the carriage is arrested in its motion by the adjustable stops it', rising from and attached to the frame A. The carriage I is formed of two parts L Z, hinged together at m, so that while the lower portion l rests on its ways e the upper portion 7c may be tilted up on one side, as shown in red, Fig. 3. This tilting or lifting of one side of the part 7c is performed at stated intervals in the following manner: A bar K, rather longer than the carriage I, slides in notches in the cross-pieces n of the lower part of the carriage. Near each end of this bar K is a wedge-shaped piece O. As the carriage I travels on its ways e toward the right, the projecting end of the barK strikes against the stop t" before the carriage completes its movement in this direction and the bar is driven back in its notches into the position seen in red, Fig. 2, with the wedges O beneath the upper portion 7o of the carriage, tilting it, as seen in red, Fig. 3, and support- ,ing it in this position until the carriage I travels back toward the other-end of the frame A, whenlthe bar K strikes against the stop i and the Wedges are knocked from under the part lo, and it falls back into its normal position. Thus each alternate trip of the carriage I- on its ways is mad-e with the upper part lo in a different position. Set-screws 79 strike on the lower part Z and adjust the distance to which the upper part k falls back when the wedges are knocked from under it.
A heavy bar L is carried on top of the carriage I. It is bolted at each end to a rackbar q. These rack-bars slide in dovet-ailed ways r running transversely across the carriage, and are fastened by screws s to the upper part k of the carriage. To the top of one ofthe rack-bars q is attached a short flat bar or dogt, which is adjustable on the rack-bar by a screw and slot. One end of this dog is bent up, as seen in Fig. 2. To the top of the bar L are secured the clamps M, which are moved up and down a short distance in the bar by their screws N. Each of these clamps has a projecting arm, Fig. 3, which projects over the side of the bar L and is furnished at its end with claws. next the saw is hung by slotted straps O the toothed rest P (seen dotted in Figs. 2 and 3,) which is adjusted at the proper height to suit the length of the bolts from which the shingles are to be cut, and is secured to the bar L bythe screws u passing through the slots in the straps O. The block or bolt to be cut is To the barL on the side e renee placed in the machine with one end on the teeth of the rest P and the other against the claws of the clamp M, which is screwed down onto it, holding it firmly. There being one clamp for each bolt, (the machine represented in the drawings carryingive bolts) the bolts are so placed that the middle of their length will be in a horizontal plane passing through the joints m, at which the two parts it Z of the carriage l are hinged. The bar L is fed for ward toward the saw in the following manner: Running lengthwise through the carriage I and having its bearings in the part It of the carriage is a shaft Q, which projects at each end beyondthe carriage. On this shaft are pinions which gear with the rack-bars q, and have at each end a ratchet-wheelR, which is actuated by pawls e, hung on the weighted arm cfa crank-lever S, which plays loosely at its elbow on the shaft Q, the other longer arm of this lever hanging down, as seen in Fig. 8, and resting against an adjustable stop w, attached to the end of the carriage.
Attached to cross-pieces at each end of the frame A is an adjustableV dog T, against the inclined edge of which the longer arm of the swinging lever S strikes cach time the carriage arrives at either end of the frame A, swinging the lever therequisite distance and feeding forward the bar L. After the arm of the lever S has completed the feed itpasses along against the straight edge e of the dog T. This form of the adjustable dog T enahles me to give the required feed to the bar L Without making it necessary to arrest the motion of the carriage at the exact moment that the feed is finished. A rod U, supported in bearings y, attached to the top of the carriage, serves to lift the pawls o, the bent ends of the rod passing under them. When the pawls are lifted, the bar L is no longer fed forward, and may be run back by the handwheel V on the shaft Q when it is necessary to commence with a fresh lot of bolts. The distance to which the bar L may be fed forward is regulated by the adjustable dog t, the bent end of which strikes against a pin projecting down from the rod U and lifts the pawls o, thereby stopping the feed.
Operation: The bolts from which the shingles are to be out having been secured by the clamps M, as above described, and the bar L moved back, the pawls o are allowed to drop onto the wheel R. Motion being communicated to the shaft C, the saw D is driven' in the direction of its arrow, Fig. 2, and the shaft F is revolved in the same direction. One of the cords f is wound upon its drum, which is clutched with the shaft F, and the other pulley, bein gloose on the shaft, allows its cord to unwind, andthe carriage I is drawn on its ways c to one end of the frame A, the saw cutting a shingle from each bolt. Suppose the first cut to have been made with the upper partv of the carriage I in the position shown in black, Fig. 3, with the wedges O from. underv it, as in Fig. 2, and the point or thin part of the shingle uppermost. Then after the shingles are cut and the carriage arrives near the end of the frame A the bar K strikes against the stop i and drives the Wedges O under the part 7e of the carriage and tilts it into the position seen in red, Fig. 3, vibrating the shingle-bolt a short distance on its center, (it having been placed, as before explained, in a horizontal plane passing through the hinges om) throwing forward toward the saw the upper end and drawing back the lower end of each bolt, so that. the next cut will obtain a shingle in a reversed position from the first, or with the point of the shingle down. After the motion of the carriage has driven in the bar K it continues on and the hangingarm of the lever Sstrikes against the inclined edge c of the dog'l on the frameA and swings' the lever, causing the pawls o to move the ratchet-wheel R, and through the pinions and rack-bars q to feed forward the bar L the thickness of a shingle and the saw-scarf at the middle of its length. The motion of the carriage I is arrested by striking against one of the stops i? il at each end of the frame A. The instant before it strikes, however, against the stop at the end toward which it maybe traveling one of the adjustable dogs g h, attached to the front of the carriage, trips the tu mblingbob H, which moves the long arm of the lever G and slides both the pulleys a l) longitudinally on the shaft F, unclutching the one which has been winding up its cord f and clutching the other, reversing the motion of the carriage I. When the carriage arrives near the other end of its ways, the rod K is pushed by the stop in the opposite direction andthe blocks O are knocked from under the part 71:,which drops into its normal position, which is regulated by the set-screws p, that the shingle may have the required taper from butt to point, the motion of the carriage again causing the bar L to be fed forward, as before, and the tumbling-bob H again reversing the direction of the carriage.
`It will thus be seen that one trip of the carriage I on its ways is made with the shinglebolts in one posit-ion, or with one end advanced and the alternate trip with them in another position, or with the other end advanced, cutting the shingles alternately in areversed position, (the saw cutting at each trip,) requiring a uniform feed motion of the thickness of the shingle in the middle of its length and the saw-scarf, instead of a varied feed motion, as has heretofore been necessary in machines of this class.
Then the bar L has been fed'up sufficiently far, the bent end of the adjustable dog t comes into contact with the pin on thc lower side of the rod U and lifts the pawls v out of the notches in the wheel R and the feed motion ceases.A Vhen the pawls are thus lifted,
' the bar L may be run back by turning the 2. The sliding rod K and wedges O, oonstrnoted and operating in the manner substantially as herein set forth.
