IMPROVEMENT IN SHINGLE-NACHINE.

The Schedule referred to in these Letters Patent and making part of the same To Il whom it may concern Be it known (that I, SAMUEL MfKrNoalof the city of Lancaster, in the State of lem1s \'lvania, have made new and useful Improvements on ,Machines for Gutting and llaning Shingles; and l do hereby declare that the lfollowing is a full, clear, and exact description ofthe construction and operation of the saine, rel'erence being had to the accompanying drawings, making a part of this` specification, in which- .Figur'e l is a perspective view ofthe machine, with my improvements in place Figure 2 is a side elevation.

Figures 3, 4, and 5, detached parts, shown separately.

lhe nature of my invention consists in the use of 'two separate beds, one adjusted byset-screws andthe other on elliptic sprilglgs, both held in a box o1' sidepieces', and operating in unison, furnished with knives, soas to split oli' and plane. a shingle on one side in the forward motion, while the bolt and severed slice remain stationary, which, in the back motion, drops .on to the bevelled or finishing-bed, where the upper surface is planed and tapered to finish the shingle, by means oi' a crank, actuating the boxed plates back and forth under certain iixed portions ot; the machine. To enable others skilled in the art to lnake and use my invention, I wilt now describe its construction and operation.

Any suitable frame-work, provided with central uprights U, spur-wheel, crank, and connecting-rod, to.

gire a. back -and tin-ward motion to the beds B and M,

'between the side-pieces (l, which arel made to slide in fixed grooved rails A A', horizontal or inclined in their position, and supported by uprigl|ts,'in the ordinary manner, and as shown.

The planing and riviug bed B 'is supported upon a pair ot' elliptic springs, and-made adjustable, centrally, by a screw-holt, allowing thepplate to move up and down between the side-pieces or box-ends C C.

This plate B is cut out with projecting ends, across f which a planing-knife, K, iig. 5, is set and adjusted with the bed, the springs underneath keeping the planer up to its work, while at the saine timlI they yield when grained pieces offer t-oo much wood, and secures the machine against breaking by too great a strain.

Over the planing-knife K is the living-knife I, secured to the top of the side or box-pieces C C, projecting a little beyond the planer K.

This living-knife .I wedges downward, resisted by 'the action ofthe knife K, on the spring'bed B.

The central posts U U rise above the beds, supporting on the one side a drop or head-block, lI, mov--v ing up and down inl grooved endpieees,"and notched out in the lower corners, to allowitto drop on the -forwardv and unitedacmss, so as to suspend this cross'- piece above the planer K and under-the living-knife I, in order to hold the slicel riveu oii'and beingplaned, without interfering with the action of the knives, passing the one under and the other over it, inthe forward motion of the'boxed beds M B, the bed M being adjusted by set-screws, to give it the desired slope or taper for the shingle, and is in close' connection to the spring-bed B.

Between them are the lifters'P, for raising the spring-roller O N on thesidesof the raised portion of the box-pieces C C, and ,also the wedged-piecesz on the top ofthe same,-to raise 'the cross-head or dropplate-H, to allow the passage. of the riviug-knil'e.

The stationary knife Ris bolted across the machine,

on to the top ofthe outer guide-railsA A, and not only planes the upper surface ofthe shingle, but gives it the desired tapering out, held by the spring-roller N O, and supported by the carrier Q. in their fixed position, through the adjustment and back-actionof the bed M.

The operation may be briefly stated:

supposing the beds back their full stroke, the. boltof wood S cut .to lengt-h, laid upon the yplaning or kspringrghbed B, fbutting against the head-block 0r plate H. In this position the.,riving-knite and planer I K are in the rear of the bolt, which latter cannot move forward.

The action'of` the crank and connecting-rod draws the beds B M forwardnnder the bolt, riving ofi` a slice and planing it from end `to end, the slice. riven oillnd planed being held in place bythe springtongue G during the operation. The back-action of the beds or combined box would now push, or rather carry the bolt back. This the attendautprevents, by placing his hand on the bolt, allowing the severed and partially planed piece to drop down upon the adjusted bed-plate M, where it is subjected to the-stationary knife R and spring-roller N O', where the upper surface is planed off and the. proper taper given to finish the shingle by the time thel beds are again drawn forward to rive and plane another piece, as the nished shingle is released and drops to the ground, thus each -revolution of the crank-wheel iinishes a shingle. The number cut in a minute is governed by the speed ofthe machine.

I am aware that automatic dogs might be attached, to hohl and govern the bolt, but'J w'ould be less efiicient than the slight attention required given by band.

I am aware that various devices are.empi0yed and patented i'or cutting and sawing shingles; but I am not aware of a machine in which the. bolt and riven piece are held in place while being riven and planed on the under side, aml the piece dropped from. one bed upon the other, and there bevelled and planed on the upper side, by the 1back and forward motion of the separate beds moving 'in unison to perform these functions, in combination with the stationary appliances described. `Iherefore, I do not claim the planing, riving, and tapering-knives, nor the roller and straight and tapering-faced beds or plates, sep` mately considered; not` doi I claim combining, in asingle reciprocating plate, a. straight face. and a tapering.; face, with an ntfs-et between them, and a. movable ti'oe, i. c., having motion in itself'.

What I claim, and desire to secure ent, isfi rlhe -arrangemcnt of a shingle-machine, provided with t-wo beds M B, in a line with each other, made separately adjustable. between the side rails C, when the bed B ssupported on springs E, or their equivalent, and earries the planer I and riving knife K, as shown, together with the spring-tongue or holder G suspended, and all operating jointly, substantially in the manner and for the purpose, speeiiied.
