Description

UNTTE JOSIAH H. GIBBS, OF GRAND RAPIDS, MICHIGAN.
liViPROVEMENT IN MACHINES FOR BORING BLINDS.
Specification forming part of Letters Patent No. 52,409, dated February 6, 1866.
To all whom it may concern:
Be it known that I, JOSIAH H. GIBBS, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and Improved Machine for Boring Blinds and other Articles, and for Spacing Articles Generally; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a transverse vertical section of my invention, taken in the line 00 as, Fig. 3; Fig.2, alongitudinal vertical section of the same, taken in the line y y, Fig. 3; Fig. 3, a plan or top view of the same.
Similar letters of reference indicate corresponding parts.
Thisinvention relates to a new and improved machine for boring blinds, and also for boring articles for mortising, and any article which requires to be bored at certain distances apart, or for spacing articles for other purposes.
Theinvention consists in anew and improved means for spacing or regulating the distance between the holes so that the wood may be bored accurately, as may be required. This means consists of a scroll-cam with a curved rack fitted therein and arranged with a dog, toothed wheel, and a sliding rack, as hereinafter fully shown and described, whereby the stick or wood to be bored may, with the greatest facility, be adjusted .or moved relatively with the anger or bit, so that the work may be done in an accurate and perfect manner.
A represents a framing, which may be constructed in any proper manner to support the Working-parts, and B is a shaft placed horizontallyin the upper part of the framingA, and having a pulley, O, placed loosely upon it, said pulley being connected with the shaft, when desired, by means of a clutch, D, which is operated by a shipper, E, composed of two levers, a a, connected by a rod, 1). (Shown clearly in Fig. 3.) This shaft B has a cam, F, upon it, in which a pendent pin, F, attached to a sliding frame, G, works, said frame working on guides 0 c on the framing A. This frame G has a shaft, H, placed longitudinally in it, an anger or bit, I, being in one end of said shaft, and the shaft is rotated by a belt, J, from a driving-shaft, K, in the lower part of the framing A. The pulley O is also rotated by a belt, L, from said shaft.
From the above description it will be seen that by turning the shaft K a rotary motion will be given the shaft H, and also the anger or bit, and a reciprocating motion given the frame G when the pulley O is connected with the shaft H, the latter movement being produced by the cam F and pin F, and feeding the auger or bit to its work and withdrawing it therefrom.
M is a sliding rack, fitted transversely on the framing A near the end of the anger or hit I, and gearing into a toothed wheel, N, on
a shaft, 0. On this same shaftO there is placed.
loosely a cam, P, composed of a wheel having a spiral grooove, d, in its outer side, in which a curved rack, Q, is fitted loosely, (see more particularly Fig. 1,) and a cam, F, is also placed on said shaft, to act against a bar, S, connected with a lever, S.
To the wheel N an arm, B, is attached, said arm passing around the edge of the cam P, and having afork, e, atits end, which fits in a groove, f, in the hub of the cam P. This arm fits in a notch of the rack Q, and connects the latter with the toothed wheel N, so that when the wheel N is turned by sliding therack M, the rack Q will be moved in the cam.
S is a dog, one end of which is connected by a joint to lever S and the opposite end made to engage with the rack Q by means of a spring, T. The end of the dog S which engages with the rack M is of considerable depth, as shown in Fig. 1, and the spring T, which keeps the dog engaged with the rack, projects through the end of the dog S and extends past a pin, g, on the lever to of the shipper E.
On the framing A there is placed a bedplate, U, one-end of said bed-plate being near the end of the anger or bit, and having a spring, V, upon it, which serves as a clamp to keep the stick W to be bored down on the bed-plate, the opposite end of said stick being secured to the end of the sliding rack M by a screw, X. (Shown in Fig. 1.)
The operation of the device will be readily seen. The stick W is fed to the anger or bit by means of the sliding rack M, the distance of the movement being regulated by the dog S and the rack Q, the former being moved by the lever S and bar S, acted upon by cam F,
wheel N and arm R also moving, and the cam P turning with them by friction, and the rack M moving or feeding the stick. The sliding rack M, in moving in the direction indicated by the arrow, Fig. 3, will feed the stick W the distance of one tooth of the rack Q each time the anger or bit is being drawn back from the stick. The length of the spaces be tween the auger or hit holes may be varied with the greatest facility by simply changing the position of the rack Q in the spiral groove 01 of the cam P, which may be readily done by turning the cam P, which will cause the rack Q to approach or rcccde from the center of the cam. The nearer the rack Q is to the periphery of the cam P, the shorter the spaces will be between the anger or hit holes. the spaces being increased in length by adjusting the rack toward the center of the cam-wheel. In turning the cam-Wheel for this adjustment of the rack Q, the wheel N and arm 1% are, of course, stationary, the cam-wheel, it being understood, is placed loosely on the shaft of wheel N.
The whole arrrangementis extremely simple and efficient and admits of the anger or hit holes being bored at a greater or less distance apart, as may be desired, and the changes made with the greatest facility.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The cam 1?, formed of a spiral groove made in theside ofa wheel, in connection with the rack Q, fitted in said groove, the toothed wheel N, arm R, connected with the rack Q, and the sliding rack M, all arranged, in connection with an anger or hit or other tool, to operate in the manner substantially as and for the purpose set forth.
JOSIAH H. GIBBS.
