SHINGLE-MACHIN.
SPECIFICATION forming part of Letters Patent No. 272,639, dated February 20, 1883.
. p Application llcd September 19, 1882. (No model.)
.To all lwhom it may concern:
Be it known that I, JOHN P. BOWLING, of Guthrie, in the county of Todd and State of Kentucky, have invented a new and useful Improvement in Shingle-Machines, of which the following is a lull, clear, and exact description, reference being had to the annexed drawing, forming part of this specification.
The object of this invention is to provide a riving device for a shingle-machine, which shall be adapted to rive bolts of the harder woods, as hereinafter fully explained.
In4 the drawing is shown aside elevation, partly in section, of a shingle-machine enibodying my improved riving device.
A represents an upright wrought-iron or steel shaft, about two inches in diameter, supported in suitable bearings, and having a double-acting crank, a, sccured'to its upper end. rlhe throw of each wrist of the double crank is to be about live and one-half inches from the center of said shaft. and to the wrists 4frame tittino in rooves c at the sides of' the box in such manner that the latter may be given a reciprocating; movement within the frame, while the box B Lis supported upon the upper surface of box B. rlhe box B is constructed with a chamber, d, extending nearly from one end thereof to the other, with a twoedged knife, d', secured to the under'sides of the box crosswise at the center, and two gages or adjustable bottoms, e e', are hinged to the box B, on opposite sides ofthe knife, with their free ends toward each other. The gages are to be about sixteen inches in length, and their inner ends are to be about three inches from the adjacent edges of the knife to leave room for the piece rived ofi' the bolt to drop out at either side of the knife. The gages are supported in position to close the chamber d at the bottom by means of a frame, e?, which extends from the center of one gage to that of the other, and which is pivoted at its center, on opposite sides, in the verticallyadjustable supportsf.
The box B' is 'constructed with a chambenf', in the ends of which are secured pieces g, which project downward into the chamber d of box B, and serve to form the hopper in which the bolt is to be placed. With this construction the bolt is made to move, with the box B', against the knife, which moves with the box B in the opposite direction, whereby only one-haltl the stroke is required that would be necessary if either the bolt or the knife were stationary. The weight of the bolt upon either of the gages e e will ca'use the balanced' frame e2 to dip at that end, whereby that part of the bottom of chamber d will dip the thickness of a shingle below the knife, while the other part of the bottom will rise to a level with thev knife to allow the rived shingle to pass underneath the knife. By means of the slotted support f the balanced frame e2 may be adjusted vertically, so that the gages may have greater or less play to vary the thickness of the shingles.
At the lower end of the vertical shaft A is shown a planing device for planing the piece rived olic the bolt. This device consist-s of; a bed-piece, D, having seats h for the shingle to be planed, a planing-knife,j, connected to the shaft A, land a roller, m, f'or holding the shingle firmly in its seat during the operation of planing. As this part of the shingle-machine is made the subject-matter of a separate application, it is not claimed in the present applicatlon.-
Having thus described my in vention, what I claim, and desire to secure by Letters Patent,
l. The combination of the lower box supported in the frame and adapted to have longitudinal movement therein, the upper box having a hopper for the bolt projecting down into the lower box, upon the edges of which box the upper box is adapted to slide, and the knife and gages secured underneath the lower box, substantially as shown and described.-
2. The combination ot' the upper box having a hopper for the bolt projecting downward Ainto the lower box, the lower box having a two-edged knife at the center, the hinged gage or bottom at each side of the knife, arranged with its free end inward, and the balanced frame adjustably supported under the said gages, substantially as shown and described, and for the purpose set forth.
