SPUDDING ATTACHMENT FOR DRlLLlNG-i-MACHlNES.

SPECIFICATION forming part of Letters Patent No. 771,036, dated September 27, 1904:.

, Applicationld February 2,1904. serial No. 191,736. No moda.)

T0 all whom, t may concern:

Be it known that I, WILLIAM L. BARTON, a citizen of the United States, and a resident of Carbondale, in the county of Laclawanna and State of Pennsylvania, have invented a new and useful Improvement in Spudding Attachments for Drilling-Machines, of which the following is a specification.

My invention relates to an improvement in drill -machines, and more particularly to a spudding attachment therefor; and to this end my invention consists in a novel method of applying the rope or cable to the working parts of the machine in combination with auxiliary devices carried by the machine, by means of which I am able to operate the walking-beam in the same'manner as though I were drilling with a temper-screw-that is, the downward movement of thewalking-beam is the operative movement. Furthermore, Ican drill from one hundred to one 'hundred and ifty feet without removing the rope from the sheaves, the walking-beam maybe stopped, and the tool withdrawn from the well almost instantaneously without causing the operator to move from one position. It will thus be seen that the action of the machine is under instant control.

In the accompanying drawings, Figure 1 is a view in side elevation of my improved spudding device; and Fig. 2 is a top plan view thereof, parts broken away to betterkdisclose the invention.

A indicates the frame of the machine mounted upon suitable wheels. A post or standard 1 is supported upon the frame, to the upper end ofA which post /is pivotally secured the walkingbeam 2, provided with pulleys or sheaves 3 4, one locatedon either side of the fulcrum of the walking-beam and preferably on the same side of the beam, as shown. These pulleys are rotatably mounted directly on the beam and are carried therewith during its oscillatory movements. The frame is provided with the usual derrick 5, having a crownsheave 6 located thereon. Journaled on the frame is the winding-drum 7, `which drum is operated by means of the drive-shaft 8, driven by any suitable means. (Not shown.) The walking-beam is operated by means of a connection extending between the drive-shaft and the rear end ofthe beam in the manner shown, the forward end of the beam being provided with a hook or other suitable means for the support of a temper-screw. (N ot shown.) Now, a pushing stroke is much weaker than a pulling stroke of the pitman and tends to strain the machine, in view of which I provide an additional stationary sheave 8', rotatably mounted on the frame at a point opposite the drum and beneath the forward end of the walking-beam, and the rope 9 is then led from the winding-drum to and beneath sheave 8, thence upward and over sheave 3 near the free end of the walking-beam, thence beneath the sheave 4 on the opposite side of the fulcrum of the walking-beam, thence upward and over the crown-sheave, and thence down to the tool. With this arrangement of parts the downward movement of the free end of the beam caused by the upward push of the operative mechanism at the rear end of the beam causes the rope to slacken and permit'the tool to descend, the upward push being aided by the pulling weight of the tool, so thatamucli better stroke is obtained with a minimum of exertion.

It is evident that changes might be made in the form and arrangement of the several parts describedavithout departing from the spirit and scope'of my invention, and hence I do not desire to limit myself to the exact structure herein set forth; but,

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a drilling-machine, the combination with a suitable support, a walking beam, sheaves mounted directly on the walking-beam and moving therewith, a winding-drum and a derrick provided with a crown-sheave, of a stationary sheave, a rope leading from the winding-drum tothe stationary sheave thence to the sheaves on the walking-beam and thence over the crown-sheave and means for winding or unwinding the rope.

2. The combination, in a drilling-machine, with a Walking-beam, sheaves located on either side of the fulcrum of the beam and carried by the beam, a crown-sheave and a windingdrum, of a stationary sheave and a rope ex- IOO tending from the drum to and beneath the stationary sheave, up and over one of the sheaves on the walking-beam, across and under the opposite sheave on the walking-beam and thence up and over the crown-sheave and means for rotating the drum.

3. In a drilling-machine, the combination with a walking-beam, a plurality of sheaves mounted directly on the walking-beam and carried thereby, the sheaves located on either side of the fulcrum of the Walking-beam, a crown-sheave and a winding-drum. the latter located at the rear end of the walking-beam, of a fixed sheave located opposite the winding-drum and at the forward end of the beam, a rope passing from the winding-drum to and beneath the fixed sheave, up and over the sheave mounted on the forward portion of the walking beam, backward and beneath the ing witnesses.
