SPECIFICATION forming part of Letters 1Patent No. 735,898, dated August 11, 1903.

I Application filed April 11, 1903. Serial No. 152,199. (No model.)

To all whom it 721/04 concern:

Be it known that I, RANsoM D. PATTERSON, a citizen of th e United States, residing at Okemah, in the Greek Nation, and Indian Territory, have invented a new and useful Well- Drilling Machine, of which the following is a is adapted to be operated by one man, who is able bytthe construction of the machine to control the movements of the drill and direct the draft-animals furnishing the power necessary to operate the machine.

Vith the above and other objects in view, which will appear when the invention is more fully understood, the same consists in'the' construction and combination of parts of a well-drilling machine hereinafter described, and shown in the accompanying drawings, forming a part of this'specifi'cation, in which corresponding parts are designated by the same characters ofreference throughout.

In the drawings, Figure 1 is a plan view of the machine, and Fig. 2 is a view in side elevation. showing the arrangement of the parts of the clutches by means of which the rope-winding drum is locked in engagement with the rotatable platform and the base of the machine Fig. 4 is a detail view insection showing the structure and operation of the clutch 8.

Referring to the drawings by reference characters, 1 designates the base. of the machine, which is preferably formed of heavy, timbers firmly secured together and compris-z ing the beams 2 2 and the superstructure 3, having the radially-disposed arms 4: 4 4:, &c.

Rotatably mounted on the base 1 is a rope winding drum 5, provided with a clutch 6, by.

Fig. 3 is a detailview in perspective ber 15 of the frame 14 is a frame 23, COD'IPIIS:

the mechanism for operating the drillin the drill-hole. The platform 7 is provided with a clutch 8, by means of which it may be locked firmly into engagement with the drum 5, so that the platform and drum may be caused to rotate together under certain circumstances. At the center of the platform 7 is provided a circular opening 9 to permit'the passage of the drill and drill-cable.

1 Rising above the platform 7 and firmly secured thereto is an upright frame composed of the inclined members 10, connected at their tops, as shown, and having their lower ends separated, so as to form a firm base for the 'frame.

Secured upon two of the inclined members 10 is a shaft 11, upon which is rot'a-tably mounted a pulley 12 for supporting the drill-cable 13. Also mounted on the platf0rm7 is a frame 14, comprising a base mem ber 15, the long oblique member 16, and the short oblique member 17, united to forma triangle, as shown, and having mounted thereon the pulleys 18 and 19, which are carried by the obliquemembers 16 and 17. At the point of attachment of the long oblique member 16 to the base member 15 there is mounted a bracket 20, at the end of which is provided a short shaft 21, upon which is journaled a pulley 22 at an angle to the horizontal plane, as shown. c

Disposed at right angles to the base meming the two parallelbars 24 24 and the'crossbar 25; The frame 23 serves as a support for the rock-shaft 26, one end of the shaft being journaled inthe cross-bar 25 and the other end upon the base 15 of the frame 14,

which forms the inner end of the frame 23. The ro ck-shaft 26 is provided at its outer end with the rigidlymounted tappetarm 27, adapted to engage the stationary projecting arms 4, provided on the base, so as to rock the shaft 26 for the purpose presently to be explained. -Near the inner end of the shaft 26 are rigidly secured thereto the arms 28, which extend at right angles to the shaft 26 in a direction directly opposite that in which the tappet-arm 27 is disposed, so that when the tappet-arm 27 is directed downward the arms 28 will be directed upward. Between the free ends of the arms 28 is mounted a small pulley 2.) upon a shaft 30, mounted in said arms. The arms 28 are so disposed with reference to the upper portion of the frame 14 and the pulleys 18 and 19 carried thereon that the pulley 29 lies in substantially the same plane as the pulleys 18 and 19 and is adapted to engage the drill-cable, which passes over said pulleys 18 and 19, as shown.

The means for imparting rotation to the platform 7 comprises a sweep 31, rigidly mounted thereon, as shown, and braced by'a stay rod or wire 32. The sweep 31 and stay-rod 32 form an arm to which is attached at its outer end one or more'draft-animals to furnish the power necessary to impart rotation to the platform '7 by pulling upon said arm. It will be observed that owing to the fact that the arm to which the draft-animals are attached is directly connected with the platform of the drilling-machine upon which the operator stands one man will be enabled to control the operation of the drilling-machine and also direct the movements of the draft-animals furnishing the power for operating the same.

In use the winding-drum will be locked to the rotary platform when it is desired to reciprocate the drill. When it is desired to wind the cable on the drum in order to withdraw the drill from the hole, it will be locked to the base, and when the cable is allowed to unwind from the drum to lower the drill into the hole the drum will not be locked either to the platform or the base, but will be allowed to rotate under the pull exerted thereon by the drill-cable to lower the drill in the hole. Let it be assumed that the drill has been adjusted in proper position in the hole by paying out the requisite amount of cable from the drum and it is desired to reciprocate the drill to continue the drilling operation. The platform will be locked to the drum by means of the clutch 8, and rotation will be imparted to the platform and drum by the draft-animals attached to the sweep 31. This will cause the rotation of the platform carrying the rock-shaft 26, and the tappet-arm 27 at the end thereof will be caused to contact successively with the arms 4 4 4, &c., rigidly mounted upon the base of the machine. Each contact of the tappet-arm 27 with one of the arms 4 will rock the shaft 26 upon its axis and impart a downward movement to the arms 28, between which is mounted the pulley 29, engaging the drill-cable 13. Each downward movement of the arms 28 draws the cable upward in the drill-hole and as soon as the tappet arm 27 passes out of contact with one of the stationary arms 4 the weight of the drill causes it to descend rapidly into the hole and strike against the bottom thereof, and the successive blows of the drill cause the deepening of the hole. As

the upright frame formed of the inclined members 10 is rigidly secured to the platform 7 and rotates therewith, carrying the pulley 12, the rotation of the platform must necessarily be imparted to the drill-cable 13, so that a partial rotation of the drill in the hole results at every reciprocation of the drill. When it is desired to pay out a little more cable to compensate for the deepening of the drill-hole by the action of the drill, the clutch 8 is released fora moment and the drum 5 is rotated independently of the platform 7 a sufficient distance to unwind the desired amount of cable. upon the drum in order to withdraw the drill from the drill-hole, the clutch 6 is set to lock the drum securely to the base 1, and the clutch 8, connecting the platform '7 with the drum, is released. Then when motion is imparted to the platform 7 by the pull of the draft-animals the cable will be wound upon the drum, causing the withdrawal of the drill from the hole. During this operation, in order to prevent the reciprocation of the drill from the contact of tappet-arm 27 and the projecting arms 4 of the base, it is desirable to depress the pulley-carrying arms 28 low enough to lift the tappet-arm above the level of the projecting arms 4 4 4, &c., and hold it in this position, which is indicated by dotted lines in Fig. 2.

It will be observed that the machine as described and shown in the drawings is entirely free from gearing of any sort and, with the exception of a few rods and bolts for assembling, the parts and thepulleys for supporting the drill-cable may be constructed entirely of wood. This feature is of value because the machine may be cheaply constructed by any one having ordinary skill in the use of tools if the rods and bolts required can be obtained from a blacksmith. None of the parts of the machine are of such character that special machinery is required for their manufacture, and if broken any of them may be readily replaced without sending to a distant point for a duplicate.

It is of course understood that while the machine as described and shown in the accompanying drawings forms the preferred form of embodiment of myinvention changes may be made in the form, proportions, and mode of assemblage of the parts without departing from the spirit of the invention or scope of the appended claims.

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