I ELIAS J. HILL, OF FINDLAY, OHIO, ASSIGNOR OF TWO-THIRDS TO SAMUEL J. FELLER, OF SAME PLACE.

WELL AND ROCKDRILLING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 247,192, dated September 20, 1881. Application filed March 15, 1881. (No model.)

To all whom it may concern:

Be it known that I, ELIAS J. HILL, a citizen of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented certain new and useful Improvements in Well and Rock Drilling Machines; 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, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of this invention is to impartboth a rotary and a vertical movement to the drillshaft in a machine for drilling wells and rocks.

The improvement consists, first, in the combination, with the drill-shaft provided with a lantern-wheel, rigid thereon, of a rotary gear engaging the lantern-wheel, a pair of collars or stops adj ustably secured upon the drillshaft, a pivoted lever having one end arranged between said stops or collars, and a set of camarms upon the driving-shaft arranged to act at intervals upon the lever, whereby the action of the cam-arms will cause the lever to raise the drill-shaft, and the adjustment of the said collars determines the heightto which the shaft is elevated; second, in the combination, with the drill-shaft provided with a lantern-Wheel, rigid thereon, of a rotary gear engaging the lantern-wheel, a shaft provided with a bandpulley and with a gear intermeshin g with said gear that acts upon the lantern-wheel, a collar upon the drill-shaft, a pivoted lever with one end arranged to act against the under side of said collar, a set of cam-arms upon the drivingshaft, arranged to act upon and depress the opposite arm of the-lever, and belt-connection between the driving-shaft and the band-wheel upon the shaft carrying the gear before specified, all as hereinafter more fully described.

In the drawings, Figure 1 is a side elevation of a drilling-machine constructed in accordance with my improvement, a portion of the derrick-frame being broken away; and Fig. 2 is a top or plan view of the operative parts of my improvement.

A indicates a suitably-constructed derrickframe, and B the vertical drill-shaft, which will be provided with a bit, O, in the usual way.

D refers to the lever that is pivoted between standards E, the said standards being either formed with or secured to base-plates E E. One end of this lever is bifurcated and its prongs extended so as to embrace the shaft B between two stops or collars, a a, which are adjustably secured upon the said shaft by means of set-screws.

K indicates the balance-wheel upon the driving-shaft, and P a set of cam-arms, arranged upon said shaft to act upon and depress at intervals one of the arms of the pivoted lever.

Upon the drill-shaft is secured a lanternwheel, B, by means of set-screws, or in any other suitable way; and upon the frame of the derrick is mounted a rotary gear-wheel, H, which engages the vertical bars of the lanternwheel. A smaller gear-wheel, h, upon a horizontal" shaft engages the gear-wheel H, motion being imparted to said shaft by belt-connection between a pulley, G, upon the shaft and a band-wheel, K, upon the driving-shaft l. The drill-shaft passes through suitable guides, one of which, 0, is arranged below the collars a upon the shaft, as illustrated in Fig. 1. Dur- 1ng the rotation of the driving-shaft a rotary motion istransmitted to the drill-shaft through the medium of the belt and gear-wheels, and at the same time the drill-shaft will be successively raised and allowed to drop, through the agency of the cam-arms, pivoted lever, and the upper collar upon said drill-shaft, in the following manner: As one of the cam-arms P, strikes the lever the arm of the lever adjacent to said cam will be depressed, and hence the other lever-arm will be raised so as to act against the upper one of the collars a, and

thereby raise the drill-shaft. The cam-arm then trips the lever, so as to allow the drillshaft to descend by gravity. The dotted lines in Fig. 1 represent the position of the several parts when the drill-shaft is thus raised, it being evident that the employment of the lantern-wheel will admit of the up-and-down movement of the drill-shaft at the same time that it is being rotated, by reason of the action of the rotary gear upon the lantern-wheel.

By raising either both of the collars or the upper collar alone the height to which the lever will raise the drill-shaft will be determined.

Havingdescribedmyinventiomwhatlclaim, and desire to secure by Letters Patent, is

1. The combination, with the drill-shaft provided with a lantern-wheel, rigid thereon; of a rotary gear engaging the lanternwheel, a shaft provided with a band-pulley and with a gear intermeshing with the rotary gear that acts upon the lantern-Wheel, a collar upon the drill-shaft at a point below the lantern-wheel, a pivoted lever having one end arranged to act against the under side of said collar, a set of cam-arms upon the driving-shaft arranged to act upon and depress one end of the pivoted lever, and belt-connection between the driving-shaft and band-wheel upon the shaft carrying the gear h, substantially as described.
