IMPROVEMENT lN SHlNGLE-MACHINES.

Specification forming part of Letters Patent No. 55,938, dated October 1G, 1866.

To all 107mm it may concern Be it known that I, AJM. UoNNE'r'r, of Madison, in the county ot Jefferson and State of Indiana, have invented new and useful Improvements in Shingle-Machines5 and I do herebydeclarc that the following is a i'ull, clear, and exact description thereof, which will ena` ble others skilled in the art to make and use the same, reference heilig' had to the accompanying drawings, forming part ot` this specilication.

The object et' the present invention is to rive and shave shingles directly from the bolt or block, the shaving being done in such manner that the portions ofthe shingles exposed to the weather when placed upon the roof of a building orother place will be ot' nnit'orm thickness, and notI cut across the grain, as in shingles vshaved with a gradual taper from butt to point.

In the accompanying plate ot' drawings my improvements in shingle-machines are illustrated, Figure 1 being a plan or top view of the machine; Fig. 3, a central longitudinal vertical section taken in the plane ot' the line .r .r, Fig. 1; Fig. 3, a transverse vertical section taken in the plane ot' the line y y, Fig. 2; and Fig. 4, an elevation ota portion ot' one side ot the machine.

Similar letters ol reference indicate like parts.

A in the drawings represents the main supporting-frame ot' the machine; li, the dri vingshatt, hung in suitable bearings ot' one end ol" thefra1neA,across which it extends. A crankA handle is secured to one end of shalt B, for turning the same; and D is a pinion-wheel on same end of shaft, meshing into a gear-wheel, E, placed above it, and secured to a horizontal shaft, F, extending across the machine, and turning in suitable bearings ot' its frame A. On the opposite end of the shat't F is sccured a crank-arm, G, to the outer end of which is hung a pitman-rod, Il, connecting it with a cross-head or block, I, arranged to slide in suitable ways or guides J of one end, K, ot' the machine. To the upper side ot the sliding head or block a splitter, L, is secured hybolts, or in any other proper manner, so as to be susceptible of detaelnnent and attachment at pleashre, which splitter projects, by its cutting and beveled end M, beyond the head or block toward the end ot4 the machine at which the driving-shaft is arranged, as before explained.

N is a hopper or box secured to the upper side of t'ramc A, and at an intermediate point, or nearly so, between the two ends ofthe same, into which hopper the block or bolt from which the shingle is to be split is placed, resting at its lower end upon the bottom plate, O, ot' the hopper, and against the edge, ot' the transverse horizontal knife-blade P, secured at the lower portion of the front end, Q, ot' the hopper to the main frame, and below which knifeedge the hopper is open across its width. B is a bent spring secured Ain the betteln of the hopper, and arranged to heal' upon the side ot' the block placed therein. The end S ot' the hopper toward the splitter is open at its lower portion, so as to allow the splitter to pass into it and through its entire length as it moves tbrward by the action of the crank and pitniaurod, connecting the head to which the splitter is attached to the driving-shat`t, the width of the splitter-blade corresponding to that ot' the inside of the hopper.

The block or bolt from which the shingles are to be split is pnt in the hopper N, and brought to bear against the knife-blade P, secured in its frontend, with the spring` R press ing` against its side, when, the driving-shaft being turned in the proper direction to move the splitter-blade forward or toward the hopper O, it is brought to bear upon the block therein, and, first forcing the same firmly against the knife-edge 1, thus partially indenting or marking the block across its width, it then, bycontinning its forward motion,splits the same, when the projecting piece T, placed under the splitter, (where it is secured in the sliding' head-block so as to be susceptible ot adjustment therein by means ot' a set or thumb screw, U,) then strikes against the split-ott' portion ot' the block resting upon the bottom plate of the hopper, drivingit under the knife blade, to and between revolving feed-pressure rollers V V, placed one above the other, (the lower one turning in fixed bearings, and the upper in adjustable bearings,) by which rollers the said split portion is then carried along to and between another set ot' feed or pressure rollers, l W', similarly arranged and hung in the frame A to that of the rollers V, when, having passed between the last set of rollers, it then escapes lroni the machine 3 the said split portion of the block, however, as it passes from the lirst set of feed or pressure rollers to the last set, being acted upon by a series ot' knife-blades, thc relative arran gement of which will be now explained, as well as the purpose and object of their use.

Xis a knife-blade, extending' across the 1uachine, and placed therein a little to one side of the lower feed-roller ot' the rst set in a horizontal plane, and in position for acting upon, and thus to shave or smooth, the under side ot' the split portion of the block passing between the feed-rollers V, the upper side of the said split portion of the block being acted upon and shaved by a transverse horizontal knife-blade, Y, secured at each end in the up per ends ot' a sliding frame, Z, arranged to move up and down in a vertical plane between the two sides of the mainframe A. The space or distance between the two knife-blades X and Y is equal to the extreme thickness which the butt ot' the shingle is to have, which distance, in order to produce the desired taper from the butt to the point ot the shingle, is gradually and regularly decreased by the depression ot' the frame Z, carrying the upper knife, Y, through the action of the revolving eccentric or cani A, secured to the transverse horizontal shaft F, hereinbefore referred to, upon the lower crossbar, C2, of such frame, when, this cain or eccentric having ceased to act upon the cross-bar G2, the frame is then thrown up or back to its original position by means ofthe tixed bent spring D2, upon which it rests at its lower end.

From the above it is plain to be understood that it' the cam or eccentric A2 is made of proper shape therefor the depression of the vertical frame Z, carrying the kniteblade, may be made to commence at any desired point of the length ofthe split-ott portion ot' the block passing through the feed-rollers, whereby, as is obvious, one ofthe objects of the present invention, as hereinbefore stated, (which is to have the butt or that portion ot' the shingle that is exposed to the action ofthe weather of an even 1 thickness throughout its entire length,) can be accomplished, the said cam also being made of suitable shape to allow the knife-frame Z to rise when the knife has reached the point of the shingle.

While the shingle is shaved upon the upper and lower sides and tapered upon the upper, one of its sides or edges is acted upon and shaved by thejointing knife-blade E2, fixed to one side ot' the machine and opposite to that at which the bent spring 1t bears against the block in the hopper, while against the other side of the shingle a jointing knife-blade, F2, acts, which knife-blade is arranged upon a screw-shaft, G2, extending transversely across the machine, and turning in bearings ot' the same, so that it can be adjusted to any width of shingle which may be running or passing through the machine.

From the above description it is obvious that when the split-oft' portion of the block carried through the feed-rollers W W escapes from the machine it is a perfect shingle in every respect, and [it to be used.

The feed-rollers are rotated ata uniform velocity through suitable gearing connectingthe two ot' each set together and to the gear-shaft F, the peripheries of the two rollers constituting the first set being toothed or serrated, so as to obtain amore [rm and reliable hold upon the shingle as it passes between them, and thus more rigidly hold it to the action of the various knives used, while the peripheries of the last or second set are smooth.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Splitting, shaving, tapering, and jointing a shingle by one operation by means ot' a splitter-knife, L, lower stationary knife-blade, X, upper movable knife-blade, Y, and side knifeblades or chisels, E2 and F2, in combination with suitable feedrollers,when they are all arranged together so as to operate and to be operated substantially in the manner described.

2. rlhe stationary knife-blade l), in con1bi nation with the splitter-blade I, substantially as and for the purpose specified.

3. The adjustable piece T, secured to the under side of the splitter-blade, substantially as described, for the purpose specified.

A. lil'. CONNET".
