IMPRovBn ROCK-DRILL'ING APPARATUS.
The Schedule referred to in these Letters Patent and making part of the sam a.
To all lwhom 'it may concern:

Figure 3 is a detail-sectional view, taken through the line a: x, fig. 1.
Similar letters of reference indicate corresponding parts. l i
My invention has for its object to improve the construction of my improved drill, patented Aprilf, 1864,
and numbered 42,167, so as to make it more effective in operation, and more convenient in use; and
' It consists in the construction and. combination o f Ivarious parts, as hereinafter more fully described.
I A is the main frame of the machine, the lower ends of the side-bars ot' which may be spiked, or otherwise shod, to prevent them from slipping.
To the, rear side of the upper part of the frame A, are pivoted the upper en ds ofthe brace-bars, or flame B, the lower ends of which rest upon the ground, and are held in place by rocks, or other convenient weights, piled upon them, so that themain frame A may be secured at any desired angle. v
0 is the drill, which passesthrough and works in a bearing, D, connected with the lower cross-har a of therframe A, and so constructed, that it may'he couveniently opened, to allow the drill C tobe removed,
when required.
Upon the upper end of the drill C, is formed a tenon, which enters a socket formed in the lower end of the vertical shaft, or stock E, where it is'secured in place by a set-screw, or other convenient means.
The shaft E passes up through a sleeve, F, which works in a bearing, G, attached to the centralcrossbar a2 of the ii'ame A, and which is so formed, that it may-be conveniently opened, to allow the shaft E to be taken out, when required.
H is a spring, coiled around theshaft E, the lower end of which rests against au enlargement of the lower end of the said shaft E, and the upper end of which rests against the-lower end of the sleeve F, so as to force the drill down, when released from the hoistingdevice.
The vertical shaft E is grooved longitudinally, and upon the inner surface ofthe sleeve F, is formed a tongue, which enters the 'grooveof the shalt E, so that the said shaft E may move up and down freely through the said sleeve F, but will be carried with said sleeve in its revolution.Y
v To-the upper end of the shaft E, is attached a swivel, e', to which is attached one end of a strap, I, which Ipasses over a guide-pulley, J, pivoted to the lower end of the screw K, which passes up through the upper crossbar et3 of the frame A, as shown in tig. 1. e
The other end of the strap I is conuected'with the crank L, formed .upon the shaft M,one end of which revolves in bearings attached to the frame A, and its other'end works iu a socket in the end of the shaft N.
The shaftN revolves in bearings attached to the frame A, and vto its outer cud is attached a pulley or crank-wheel to which the power is applied.
To the inner end of the shaft N, is rigidly attached a wheel, O, to the side of which ispivoted a pawl, P, which takes hold of the teeth of the ratchet-wheel Q, rigidly attached to the shaft M.
The pawl P is held forward against the teeth ofthe ratchetwheel Q, by a spring, R, as shown in lig. 3.
By this construction, the drill O is raised by the revolution of the crank L, and as soon as the said crank4 has passed its point of highest elevation, the weight of the drill, and the force of the spring H, carry it down to make the stroke. As soon as the stroke has been made, the pawl P again takes hold of the ratchet-wheel Q, and begins to raise the drill for another stroke.
To the upper end of the sleeve F, is attached :a earwheel, S, into -the teeth of which mesh the teeth o the small gear-wheel T, attached to the vertical shaft U, the lower end of which revolves in a socket in the central cross-bar a2 of the frame A, and the upper part of which passes up through, and revolves in bearings in the upper cross-bar a* ofthe frame.
V is a screw-wheel, placed upon theshaftU, above the cross-bar a, and which is 'made to carry the said shaft U with it, in its revolution, `by having a'tongue formed upon its inner surface, which enters a longitudiual groove i u theV said shaft U, thus' allowing the said shaft to move up and down freely through the said wheel V, while, at the same time, it is revolved by the revolution ofthe said wheel V.
Into the teeth ofthe screw-Wheel V, mesh the threads of the endless screw W, formed upon, or attached tothe shaft X, which revolves in bearings attached tothe up per cross-bar of theiiame A, aud to which motiouis given from the shaft N, by the band,or belt y, which passes around pulleys 'attached to or formed upon said shafts, so that the drill may be turned by the same shaft that raises it.
Upon the upper end of the screw K is placed a nut,
upon which is formed a bevel, gear, or screw-wheel, A',
into the teeth of which mesh the teeth or threads of the bevel-gear wheel B', or endless screw, attached to or formed upon the shaft C', which revolves in bearings attached to the. upper cross-bar a3 of the frame A.
'10 the outer end of the shaft C', is attached a conepulley, D', around which, and around the hand or crankwheel E', is attached a band, or belt, so that the drill may be fed down, as it cuts its way into the rock, by
K hand-power.
The ends of the cross-bar a,2 are grooved, to fit upon the racks Ff, attached to the inner sidesof the sidebars of the frame A, which said racks thus serve as guides to the said cross-bar, as it moves up and down.
The cross-har a? is kept from being raised, while the machine is being operated by the pawls G', which are pivoted to the upper side of the said cross-bar and which take hold f the teeth of the racks F', the said cross-bar heilig allowed to feed itself down by its own weight, as the drill cuts-its way into t-he rock.
' Having thus described my invention,M
What I claim as new, and desire to secure by ters Patent, is I l. The combination and-arrangement of the pawls G', sliding cross-bar a2, .spring H, with the vertical shaft, or stock E,to which the drill C is attached, and with the racks F' attached to the frame A, substan- Letpose set forth.
2. The combination ofthe pulley J, screw K, combined gear=wheel and screw-nut A', shaft C', and c onepulley D', with the hoisting-strap I, substantially asl herein shown and described, and for the 'purpose set forth.
3. The combination of the driving-shaft N, crankshaft L M, fly-wheel O, pawl P, and ratchet-wheel Q,
with each other, and with the hoistngstrap I, suhstantially as herein shown and described, and for the Y purpose set forth.
'lhe above specification of my invention signed by me, this 24th day of March, 1869.'
` JOHN CODY.
