Description
UNrTED STATES PATENT OEEICEo STEPHEi\T K. BALDWIN, OF GILFORD, NEV HAMPSHIRE.
IMPROVEMENT IN MACHINES FOR CUTTING SHOE-PEGS.
Specilication forming part of Letters Patent No. 2,725, dated July 16,1842.
,T0 all whom it may concern.'
Be it known that I, STEPHEN K. BALDWIN, of Gilford, in the county of Belknap and State of New Hampshire, have invented a new and useful Improvement in the Machine for Cutting Pegs, which is described as follow, reference being had to the annexed drawing ofthe same, making part of this specification.
The figure is a perspective view.
Similar letters refer to corresponding parts.
rlhe bench or frame A, for supporting the several parts hereinafter described, and upon which the fiuted block to be cut into pegs is placed, is made in the usual manner. A post, B, (to which one end of the knife for cutting the pegs and an arm resting on the back of the knife are attached,) is passed vertically through an aperture in the bench, being secured therein by keys or wedges, so that it can be raised or lowered at pleasure for the purpose of setting the end of the knife attached thereto higher or lower, at pleasure.
rIhe shearing-knife O, for cutting the block into pegs, is made of steel, tapered. It is attached to the post B by a bolt passed through it and a curved projection of the large end of the knife, and on which it moves or vibrates. The small end of the knife is attached to a whip-staff by a horizontal pin or bolt passed through them.
The whip-staff l) is made in the usual inanner, and is attached by its lower end to the wrist of a crank, E, on the end of a revolving shaft, F, on which there is a fast pulley, G, and a loose pulley, H, of the usual form and construction.
A sliding box, I, in which the wrist of the crank turns, is raised and lowered by keys K for increasing or diminishing the sweep of the knife by increasing or diminishing the distance between the Wrist and the knife, is combined with the whip-staff near the lower end thereof. This sliding box is a rectangular block placed in a rectangular mortise in the whip-staff of the same width as the block, but greater length, so as to allow it-su'fficient play therein, having wedge-shaped keys K inserted in said mortise at each endof the sliding box. The aperture in the box for the wrist is of the saine diameter as the wrist. The slidingframe, containing the iiuted roller for holding down the fluted block or bolt upon the bench and for drawing it forward to the knife, is composed of two vertical timbers, L L, which pass through mortises -in the bench placed at the required distance apart, and united by a horizontal transverse timber, M, mortised and tenened into the same.
The luted roller() is made the length of the frame inside and of sufficient diameter, and turns on pivots or gudgeons in said frame. Mortises or slots are made in the vertical sides of said frame to permit them to rise and fall over horizontal plates P, secured across the openings in the bench in which the frame rises and falls. Two vertical screws, Q, for raising and lowering the frame, are inserted into the upper ends of the side pieces of the frame, extending down into the aforesaid mortises and resting upon the fixed horizontal plates P of the bench,crossing said mortises. When the frame is to be raised, the screws Q are turned to the right, and when it is to be lowered they are turned to the left, the weight of the frame and roller causing it to descend. A weight, R, may be attached to lthe lower cross-bar, M, of the frame for holding down the roller upon the iiuted bolt, or to one end of a lever, S, resting upon said cross-bar M, its other end bearing against a spiral spring (represented by dotted lines at Z) placed between it and the under side of the top of the bench A.
The machine is rendered self-feeding in the following manner: Ou one end of the iiuted roller is fixed a toothed wheel, U, made like a circular saw. Over this wheel is arranged a reaching-arm, V, having an oblong mortise in the same, in which the toothed wheel turns. The upper end of this reaching-arm is attached to a vibrating bar or lever,W, one end of said bar or lever being attached to the head of the post B by a bolt, which will be the fulcrum, while its other end is passed through a mortise in a shifting block, X, which rests upon the back of the cutter C, said block X being made adjustable on said bar by keys or wedges Y, for the purpose of moving the block nearer to or farther from the fulcruni for increasing or diminishing the sweep or movement of the lever, and consequently that of the reaching-arm and toothed wheel.
A spiral spring, d, is attached to the bench and to the reachingarin for drawing down the atter.
Operation: A baud, J, leading from the driving-power, being shifted from the loose pulley H to the fast pulley G, the machine will be put in motion, and as the crank-shaft F turns it raises the knife C by the whip-staff D, and at the same time the lever WV and reaching-arm V, which turns the ratchet-Wheel U and roller O, which feeds up the fluted bolt b as far as the required thickness of the peg to be cut, and, the crankshaft continuing to revolve, brings down the knife C, makes a eut the thickness of the pegs, at the same time bringing down the reaching-arm W for a new hold ou the toothed Wheell` the arm slipping over the backs of the teeth, which are sloped downward to allow of this movement. In this manner the operation is continued until the bolt is cut in parallel cuts from one end tothe other. The bolt is then turned round and cut at right angles to the former cuts in the same manner, which completes the operation. The bolt b is previously furrowed, grooved, or sawed in parallel lines at right angles in the manner that it is required to be cut up into pegs. The teeth or ribs of the roller enter the channels or grooves of the bolt previously sawed therein.
What I claim as my invention, and which I desire to secure by Letters Patent, is
The method of feeding the bolt by the combination of the fluted roller, ratchet-Wheel, and reachingerm, and adjustable lever connected with the vibrating knife, as before described.
