PULLlNG-MACHINE FOR OIL-WELLS.

Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed April 18, 1905. Serial No. 256,196.

To all whom it may concern.-

Be it known that we, WILLIAM A. WORRELL and LESLIE FISH, citizens of the United States, and residents of Vanburen, in the county of Grant and State of Indiana, have invented a new and Improved Pulling-Machine for Oil- Wells, of which the following is a full, clear, and exact description.

Our invention relates to a machine for use in connection with the sinking and operation of oil-wells, although it may be used for other analogous purposes.

The principal objects of the invention are to provide a portable frame which can be readily taken from one well to another, with means for pulling rods and tubes and also providing means for lowering the same and for simultaneously lowering a tube and raising another into position ready to be lowered into a well.

Further objects of the invention will appear in the course of the subjoined description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a machine constructed in accordance with the principle of our invention, showing it in position for transportation. Fig. .2 is a plan view of the same; and Fig. 3 is a sectional view on the line 3 3 of Fig. 2, showing the frame in position for operation.

The drawings show a frame 10, provided with wheels 11, upon which it can be moved from one well to another in an obvious Inanner. Upon the lower part of the frame it is provided with a shaft 12, having square ends 13, by means of which it can be turned by hand, and also provided with a pair of drums 14: and 15 of different sizes. These drums are provided with ropes or cables 16 and 17 respectively. These are designed to be attached to any desired source of energy for the purpose of operating the shaft. The ropes or cables may conveniently be operated by horses and are preferably wound in opposite direction upon the drums, so that the unwinding of one will wind up the other. The shaft is also provided with a ratchet-wheel 18, and a pawl 19 on the frame engages the teeth thereof. The ratchet-wheel is provided with a cylindrical surface 20, upon which a brakeband 21 is applied. This brake-band is provid ed with a lever 22. The frame is provided also with two pulleys 23 and 24, mounted in an iron bracket 25. These pulleys are preferably of different sizes and are used for different purposes. The part of the frame upon which these pulleys are mounted is preferably made in the form of a movable extension 26. This extension is provided with a forked end 27, in which a bar 28 on the main part of the frame is adapted to engage, and it slides in a guide 29 on the main part of the frame. On this guide is mounted a pulley 30 and on the extension an eye 31. A flexible member in the form of a rope, chain, or cable 32 is designed to be attached to the eye at one end and to pass over the pulley and from there back to the shaft 12. By turning the shaft the flexible member can be wound up upon it so as to force the movable extension in an outward direction until it is in such position that the movable bar 28 can be applied so as to hold it, as indicated in Fig. 3. A hook 33 is provided for use when the device is to be transmitted, and a guide 34. is used for the drum 16.

When the device is set up to operate, the base of it is preferably placed about four feet from the well and it is leaned in the direction opposite to the side upon which the wheels are located, as indicated in Fig. 3. Guys 35 are then applied to hold it in the desired position. The extension is not raised until the frame is set up and then only when it is desired to pull rods, as the machine is tall enough to pull tubing with the extension down, and of course additional strength is secured when in this position. sion, the line 32 is fastened, as stated above, and the shaft turned to wind the line on the shaft. When the extension is raised and the cross-bar 28 placed in position, the line 32 is taken off and put aside until it is desired to lower the extension. After the machine is put in. position by means of the guys the pulling of rods is done by a line 36, passing over the large pulley 23 and fastened to the shaft 12 between the drums and the brakewheel. The other end of the line is fastened to the rod. A source of power, preferably a team of horses, is then connected with the line 16, and as they pull the rod or joint is elevated, while the pawl on the ratchet-wheel holds the shaft against motion in the wrong direction. This prevents'the dropping of the In order to raise the exten- 1 tube back into the well if any part of the pull ing-tackle breaks, as it stops the wheels at once. The pulling is continued until the joint or coupling is reached. The pawl is then thrust up, permitting the wheels to run in the opposite direction, and the joint is lowered onto the ground. This operation is controlled by the brake. The joint is unscrewed from those remaining in the well. The team is then attached to the line 17 for turning the wheels in the opposite direction, thus lower ing the joint and winding up the line on the large drum at the same time, this line being guided by the guide 34. The ratchet of course is not used in this lowering operation. To put the joints back, the line used to pull out is connected with the joint and elevated by turning the shaft until the end of the joint is high enough to enter the well again. Both the lines 16 and 17 should be wound up on their respective drums. The line over the pulley 24, which has been idle in pulling out the joints, is then fastened to the opposite end of the shaft and so connected as to coil in the opposite direction from the line 36. The other end of this line is then connected with a joint lying on the ground. The joint already elevated is now lowered into the well, the speed being regulated by the brake. As this joint is lowered, the one connected with the line over the pulley 24. is elevated at the same time by the rotation of the shaft 12. The ratchet is not used at this time.

Having thusdescribed our invention, we claim as new and desire to secure by Letters Patent- 1. A pulling-machine for oil-wells, comprising a frame, an extension movably mounted thereon and having an eye, aflexible member connected with the eye, means for operating said flexible member, a pair of pulleys of different sizes mounted upon said extension, and a flexible member passing over one of said pulleys and adapted to be connected with said means for operating the other flexible member.

2. A pulling-machine for oil-wells, comprising a movably-mounted extension having an eye, a guide for said extension, a pulley mounted on the guide, a flexible member connected with the eye and passing over the pulley, means for drawing said flexible connection over the pulley, a pair of pulleys of diflerent sizes mounted upon said extension, and a flexible member passing over one of said last-named pulleys and adapted to be connected with said means for drawing the other flexible member.

3. A' pulling-machine for oil-wells, comprisinga frame having wheels mounted upon one side thereof and a hook for draft purposes, a plurality of guys for securing the framein inclined position, a shaft mounted on the frame, two drums of difl ereut diameters mounted on the shaft, a flexible member coiled upon each drum in opposite directions, a guide for the flexible member of one of the drums, a ratchet-wheel on the shaft, a pawl for engaging the ratchet-wheel, a brake connected with the shaft, an extension movably mounted upon the frame, said extension having an eye, said frame having a guide for the extension, a pulley mounted on said guide, a flexible member connected with said eye, passing over the pulley and adapted to be connected with said shaft, a frame on the extension, a pair of pulleys of different sizes upon the frame, and a flexible member passing over one of the pulleys and adapted to be connected with the shaft.

In testimony whereof we have signed our names to this specification in the presenceof two subscribing witnesses.
