MECHANISM FOR OPERATING DRILLS.
SPECIFICATION forming part of Letters Patent No. 389,613, dated September 18, 1888.
Application filed Februaryfl, 1888. Serial No. 262,765. (No model.)
To (ZZZ whom it may concern.-
Be it known that I, WILHELM THIEM, of Bellevue, in the county of Campbell and State of Kentucky, have invented a new and useful Improvement in Mechanism for Operating Drills, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure l is a front view ofmy mechanism for operating drills. Fig. 2 is an edge View of thesame; Figs. 3 and 4, vertical sectional views of the holder for manipulating the drills, and Fig. 5 detail perspective view of the lower portion of the frame.
The object of my invention is to construct a mechanism for operating drills by hand and it consists of a vertical frame having centrally a horizontal cross-bar, to which bar and the cross-beam above is journaleda vertical twistbar, the lower end of which has a socket for attaching thereto a bit, and the upper end of which is provided with a balance-wheel or arms. This twist-bar carries a tubular sliding piece provided with hinged pawls, and over this tube is a sliding holder tubular in form, so that when the hand grasps the sliding holder and presses it downward it will slide to the lower end of the tubular piece and cause the pawls to engage with the twisted grooves of the bar and rotate the same. Two weights at tached, respectively, to the tubular piece and to the slidingholder serve to raise these parts when the downward pressure is released. The lower halfof the frame is provided with avertically-sliding frame, on which the material to be drilled is placed, and this frame is counterbalanced by suitable weights.
In the accompanying drawings, A represents a pair of posts parallel with each other mounted on a suitable base, B, and secured to a similar pair of posts by means of the top beam, 0, and central cross-bar, D. The posts thus form guideways on each side, between which the counter-balancing weights are placed, as will be hereinafter shown.
' Eis avertical shaft journaled to the beams G D midway between the posts A A. The upper end of this shaft is provided with a balancewheel or weighted arms,F, and at its lower end a head, G, provided with a socket to receive a bit, H, and a thumb-screw, G, on one side for tightening the bit. The shaft is further provided with a collar, I, ashort distance above the journal in the beam 0, anda lever, J, fulcrumed to the beam 0, has one end placed under this collar, the opposite end being constructed so that it projects slightly beyond the beam 0. The shaft E being capable of a limited vertical motion the lever J is employed to raise it when desired in the operation of boring.
The shaft E is constructed with a twist, or, preferably, with twisted grooves K,on opposite sides. The construction shown in the ord nary twist-bit will answer for this purpose satisfactorily.
In Figs. 3 and 4 I show vertical sectional views of a tubular piece, L. This is made of suitable size to fit loosely on the twisted shaft E. On each side it is provided with a slot, M, to which slots are pivoted centrally levers N, Which are slightly curved, the lower ends having inwardly-turned pawls or teeth 0. The lower end of the tubular piece L has a lug or stop, 1?. This tubular piece is designed to receivethet11bularholderQ,whiehslidesthereon. The upper end of the tubular holder Q has at one side a lug or pin, R, while thenpper end of the tubular piece L on the opposite side has a similar pin, R, to which the weighted ropes are respectively attached. In the beam 0,011 one side of the shaft E, are two grooved pulleys, S S, one of them being directly above and in line with the pin R on the tubular holder Q, and the other in line with the weight U, between the posts A. A rope, T, attached to the tubular holder Q, passes over these grooved pulleys S S, and thence down to the weight U. In like manner grooved pulleys S S are located in the beam 0 on the other side of the bar E, and a rope, T, attached to the tubular piece L, passes over these pulleys and thence down to the weight U.
The lower half of the frame, or that portlon below the central beam, D, is provided with a vertically-movable frame or table, the vertical side limbs, V, of which are properly gained, so they will slide between the parallel posts A. These vertical pieces are joined at the r upper and lower ends by means of cross-pieces or tables W, which tables are provided centrally with apertures TV, through which the bit H can pass. Each vertical limbVhas on its side an eccentric or cam lever, X, which in operation binds against the post A.
The object of this is to hold the sliding frame in any position desired.
Y Yare grooved pulleys located directly below the central beam, D, between the posts A and Z Z, weights which slide between the posts A.
Z Z are ropes attached to the frame and weights in order to counterbalance the frame and elevate it.
The operation is as follows: The bit H being adjusted, the article to be drilled or bored is placed on the table \V of the sliding frame. If the bit is a short one, the upper table can be used. Ifalong bit is employed, thelower table can be used. The weights Z are preferably heavier than the table, so as to elevate both the table and the article to be bored, which may be placed thereon. The operator then grasps the tubular holder Q and forces it downward with a rapid motion, causing it to slide down on the tubular piece L until it reaches the stop P, as shown in Fig. 4, and then both tubular pieces are moved downward on the twisted rod E. The noses or pawls O of the levers N are forced into the grooves of the rod E, and thereby cause the latter to rotate. When these tubular pieces have reached their lowest limit, they are drawn back suddenly, and the effect of the initial motion is to return the tubu- 0 lar holder Q to its original position, as shown in Fig. 3, thus disengaging the pawls O. The balance-wheel or weighted arms F in the mean time continue the motionof the rod E. The operation of the tubularholder is then repeated, 5 the weights U U being utilized to draw up the tubular holders after each downward motion.
\Vhat I claim as new is 1. In mechanism for operating drills, a frame having therein a vertical rotatable twist-shaft provided with a balance-wheel or arms at its 0 upper end and a bit-socket at its lower end, in combination with a tubular piece and a tubular holder sliding thereon having pawls for engaging with the twist shaft or rod, and suitable ropes and weight for elevating said tubular holders, substantially as herein set forth.
2. In mechanism for operating drills, a vertical twist shaft or rod for carrying the bit, having thereon a sliding tubular piece provided with centrally-hinged levers in the sides, provided with inwardly-projecting pawls on their lower ends, in combination with a thimble or sliding holder on said tubular piece, which moves to and fro thereon for engaging and disengaging the pawls with the twist-shaft, substantially as herein set forth.
3. The vertically-journaled twist-shaft for carrying the bit, having thereon a sliding tubular piece provided with rocking levers and pawls, and the thimble or holder thereon for operating said levers, in combination with a rope and weight connected with the tubular piece, and an independent rope and weight connected with the thimble, substantially as herein set forth.
4. In mechanism for operating drills, a frame having journaled in the upper part a vertical bit'shaft, in combination with a verticallysliding frame carrying two tables in thelower part of the frame, and counterbalancingweights, substantially as herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 1st day of October, 1887, in the presence of witnesses.
