S. J. GOUOHER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO MILTON FOREMAN, OF SAME PLACE.

IVIPROVED WELL-BORING APPARATUS.l

Specification forming part of Letters Patent No. 52,64 2, dated February 13, 1866.

To all lwhom t may concern.

Be it known that I, S. J.,GOUGHER, of Philadelphia, Pennsylvania, have invented certain Improvements in lVell Boring Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the aceompanyin g drawings, and to the letters of reference marked partly in section.

A is the foundation of the apparatus, and B is a derrick to a shaft, a., at the lower part of which is secured a drum, c, having at one end a grooved pulley, D.

A rope, X, which is coiled around the drum, is carried from the latter to the top of the derrick and over a grooved pulley, b, the drilling-A tool being secured to the lower end of the rope, which passes into the well.

ln a frame, E, turn two shafts, c and c, and on one end of the latter is a crank, d, the pin ot' which is connected, by a rod,f, to one end of a walking-beam, F, the latter being supported by an upright, G. The forward end of the walking-beam projects beneath the derrick and over the mouth of the well, and is furnished with the ordinary feeding-screw.

On the shaft e are two pulleys, I and I', the former being secured to the shaft, while the latter can turn freely thereon, and at the side of the pulley I' is a smaller friction-pulley, J, for a purpose described hereinafter.

One end of the shaft e turns in a stationary bearing on the frame E, and the other end passes through the upper end of a lever, K, hung to a cross-piece, E', of the frame, and to the inner end of this shaft is secured a frietion-pulley, J

To the lower end of lthe lever K is secured a cord, g, which passes over a grooved pulley in an upright, L, of the derrick, and is attached at its end to a treadle, M 5 and on the shaft c is a grooved pulley, D', round which and round the pulley D passes a rope or hand, h. On the driving-shaft H is a broadbandpulley, N, round which a band, k, passes to one of the pulleys I or l'.

When a well has to be bored the drill attached to the rope X is brought against the face of the rock, the rope is secured to the feed-screw at the outer end of the Walkingbeam F, and the band 7c is thrown onto the pulley I, when a vibrating motion will be imparted to the walkin g-bearn, so as to raise the cutter and bring it down against the rock.

When it is required to cease drilling the band 7c is thrown onto the pulley l', which, with the friction-pulley J, is thus caused to revolve in the direction of its arrow, and should it then be desirable to raise the drill the attendant presses with his foot on the treadle M, so as to operate the lever K and bring the friction-pulley J' into contact with the frictionpulley J, a rotary motion in the direction of the arrow 2 being thus imparted to the shaft e and to the shaft a and its drum., the rope X being wound on the latter until the drill is raised from the well.

It will be seen that by means of the abovedescribed arrangement the operation of the machine may be discontinued and resumed without interrupting the motion of the driving-shaft-an object which is especially .desirable when two or more machines a-re driven from the same shaft.

I claim as my invention and desire to seto this specification in the presence of two subscribin g witnesses.
