EiPECIFICATION forming part of Letters Patent No. 3&4306, dated July 6, 1886.
Application filed January 2, 1886. Serial No. 187,365.
To aZZ whom it may concern:
Be it known that I, SIMON INGERSOLL, a citizen of the United States, residing at Glenbrook, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hand Rock-Drills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has for its object to simplify and improve the construction of this class of devices.
WVith these ends in view I have devised a novel construction, of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to indicate the several parts of the device.
Figure 1 is a front elevation, the balancewheel being shown in section, likewise the at tachmcnt of one of the legs; Fig. 2, a transverse section on the line at m, looking down; Fig. 3, a detail View showing the end of the crank, shaft, cam, &c., in elevation; Fig. 4, a longitudinal section of the entire machine on the line 3 g in Fig. 1, looking toward the left; and Fig. 5 is a detail sectional view of the cross-head and cap upon which the sprin rests, the plane of the section being the same as in Fig. 4.
1 indicates frame-work, preferably made of wood and having cross-pieces 2.
3 indicates a metallic cross-piece secured to the frame-work and provided with ears, to which the long log 4 is pivoted.
5 indicates metallic blocks bolted to the lower end of the frame-work, and provided with sockets G,'in which the short legs 7 are bolted, as is clearly shown in Fig. 1, said legs being adapted to turn when the bolt is loosened, but having no endwise motion.
8 is a sliding carriage, which moves in ways 9 in the frame-work.
10 is the upper cross-piece of the carriage, which is engaged by a screw, 11, supported in the upper cross-piece of the framework, as shown in Figs. 1 and 4. This screw is pro- 50 vided with a crank, 12, by which the carriage (No model.)
and the operating parts of the machine are raised and lowered when in use.
13 is a shaft, which is journaled in the carriage, and is provided with cranks 14.
15 is the lower cross-piece of the carriage, k
and 16 the spindle which is supported in said cross-piece of the carriage.
17 is a cross-head which rests upon collar 18 on the spindle, being held in place by a removable collar, 19, which is placed above it and secured there in any suitable manner. The ends 20 of the cross-head rest upon the carriage and give additional stability to the parts when the machine is in use.
21 is a cap covering collar 19, (see Fig. 5,) and resting upon the crosshead. This cap serves as abearing for thelower end of spring 22, the upper end of which bears against the upper cross-piece, 10, of the carriage.
23 indicates flexible straps, the lower ends of which are attached to the cross-head and the upper ends thereof to cranks 14 upon the shaft.
24 is the balance-wheel,which is loose upon the shaft, as indicated in Fig. 1.
25 is a handle upon the balance-wheel, by which it is turned. Just inside the balancewheel is a ratchet, 26, which is rigidly se cured to the shaft.
27 is a pawl, carried by an arm of the balance-wheel, and 28 a spring, the action of which is to keep said pawl in engagement with the ratchet.
29 is the drill,which may be of any suitable construction, and is secured to the spindle in the usual or any preferred manner.
The operation of this portion of my inven tion is as follows: The normal position of the parts is shown in Figs. 1 and 4. When the balancewheel is turned, the engagement of pawl 27 with the ratchet carries the shaft with IOO center, spring 22 will force the drill down violently, thus giving a blow to the rock. When this instantaneous movement of the spindle and drill takes place, it will be apparent that the shaft and ratchet must move away from the balance-wheel.
In practice I have found, owing to the flexibility of the straps, that the cranks are carried considerably past the dead-center at the bottom. Attheinstantthattheforwardmovement of the shaft and ratchet is checked pawl 27 engages the ratchet again, and the move ment is repeated to raise the spindle and drill. It will thus be seen that during each rotation of the balance-wheel the ratchet necessarily makes a complete revolution and more than half of another revolution. The exact gain that the ratchet makes upon the balance-wheel will ofcourse depend uponthe distance the drill moves before it strikes the rock. Spring 22 is necessarily made powerful, so that a very heavy blow is instantly imparted,and the shaft is as quickly engaged or picked up again by the engagement of the pawl with the ratchet. In practice it is of course necessary that the drill shall make a partial revolution after each blow, so that no two blows of the drill will strike in the same place. This rotation of the drill I accomplish as follows: 30 is a cam at the outer end of the shaft that is opposite to the balance-wheel. 31 is a rock-shaft journaled in brackets 32 upon the carriage. 33 is a downwardly-projecting arm,whichis rigidly secured to shaft 31. This arm is held in engagement with the surface of cam 30 by spring 34, one end of which is attached to the lower end of said arm and the other end to a pin, 35, upon the carriage. 36 is a set-screw for the adj ustment of arm 33. 37 is an arm which projects upward from shaft 31, and 38 is a pawl rigidly secured to said arm or made part thereof. 39 is a groove in spindle 16, and i0 a ratchet having a spline which engages said groove, and through which rotary motion is imparted to the spindle. Ratchet 40 rests upon the upper cross-piece of the carriage, and is held in place by a bracket, 41, which is secured to said cross-piece. It will thus be seen that the spindle has free vertical movement through the ratchet, as'is of course necessary in giving each blow of the drill,and, furthermore, that when the ratchet is turned the spindle and drill are necessarily carried with it. The mannerin which the spindle and drill are rotated is clearly shown in Figs. 2 and 3. It will be seen that each rotation of cam 30 imparts a forward and backward movement to arm 33, which roe-ks arm 31, thus imparting a forward and backward movement to pawl 38. At the instant said pawl is at its farthest position toward the front it engages a tooth of the ratchet, and as the pawl moves forward the ratchet is carried with it, thus imparting a partial rotation to the spindle and drill. The
' ratchet is securely held against backward movement by pawls42, pivoted to the carriage, andheld in engagement with the ratchet by spring 43.
The important advantage of my improved construction is, that it enables me to impart the partial rotation to the drill at the instant that it is stationary atits highest position-that is, just before spring 22 acts to force itdown. I thus avoid the great strain upon the parts which is unavoidable when the rotary movement is imparted to the drill either while it is rising or falling. The exact instant at which the rotation is made depends, of course, upon the timing of the machine;but I am not aware of another construction that enables the rotary movement to be given at any other time than while the drill is either rising or falling. It will of course be understood that the details of construction may be widely varied without departing from the spirit of my invention.
I claim 1. In a hand rock-drill, the combination, with the spindlc,cross-head, and spring 22, of a shaft having cranks 14, and flexible straps connecting saidcranks with the cross-head.
2. The spindle, cross-head, and spring, in combination with the shaft having cranks 14, the ratchet 26 on said shaft, flexible straps connecting said cranks with the cross-head, and a loose balance-wheel having a pawl adapted to engage the ratchet, substantially as described.
