PIPE-FULLER.

Specification of Letters Patent.

Patented June 3,1919.

Application sled August 9, 191s. serial No. 249,202.

To all fwwm it may concern.'

Be it known that I, ALBERT F. BRAUN, a citizen of the United States, residing at Clay Center, in the county of Clay, State of Kansas, have invented certain new and useful Improvements in Pipe-Fullers; and I do hereby declare the following to be a f ull, clear, and exact description of they invention, such as will enable others skilled in the art to which it ap-pertains to make and usethe same.

This invention relates to improvements 1n pipe pullers and particularly to devices for regaining pump pipes which have fallen or dropped down into the well casings or tubes.

One object of the present invention is to provide a novel and improved device of this character whereby the fallen pipe can be easily and quickly reached and grasped for the purpose of pulling the same upwardly out of the tubing.

Another object of the invention is to provide a novel and improved device of this character which includes an eflicient means for passage downwardly within the well tubing and over the pipe for the purpose of getting a rm grip on the pipe.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a vertical sectional View through a portion of a well tuibing, showing the fallen pipe therein, and the invention about t0 engage therewith.

Fig. 2 is a vertical sectional view through the invention and the well tubing showing the pipe properly disposed through the invention yand grip-pcd by the dog.

Fig. 3 is a vertical longitudinal sectional view taken on a line which extends through a plane at right angles to that of Fig. 2.

Fig, 4 is a horizontal sectional view taken on the line 4 4: of Fig. 1.

Referring particul-arly to the accompanying drawing, 10 represents the well tubing, and 11 the fallen pump pipe which is to be lifted by means of the present invention.

The present invention includes a truncated cone-shaped member 12, which is hollow, and open at both ends, as clearly shown in the drawing. Secured around the upper or smaller end of the member 12 is a collar 13, the same being out out, on one side to form a longitudinal elongated opening 14:, at each side of which is formed an apertured lug 15. Through the opening 14 is disposedy the dog 16 which is pivotally mounted between said lugs 15. This dog extends into the collar to a distance which permits it to bear against the pipe 1l, when the cone member has been lowered to such Ia point as to permit the said pipe to pass upwardly through the upper end of the cone member. Secured to the upper end of the collar 13 is a coupling member 17 which receives the lower end of the lifting pipe or rod section 18, by means of which the device is lowered into and lifted from the tubing 10. Secured within the upper portion of the cone member is a stop mem-ber 19 which is engaged by the inner' portion of the dog to limit the downward movement thereof. A coil spring 2O is secured to the inner portion of the dog and to the collar to hold the dog yieldably against the stop member.

The openings 15 of the lugs l5 are arranged in longitudinally extending oblique lines and are arranged to receive the pivot of the dog, so that the dog is capable of adjustment to bring the same closer to or farther away from the pipe to be gripped, thus enabling the dog to grip pipes of different diameters.

In the operation of the device, the cone member is let down into the well tubing, as shown in Figs. 1 and 2 of the drawing, until the upper end of the pipe is disposed within the larger end of the cone. It will be noted that the mouth of the cone member is beveled to facilitate the engagement of and positioning of the pipe therein, as shown at 12. Then, upon pushing the cone member downwardly, the pipe 11 will be passed upwardly into engagement with the dog, which dog will firmly press the p-ipe against the other side of the inner face of the collar, whereupon the device will drawthe pipe 11 from the tubing l0, when lifted upwardly.

What is claimed is:

A pipe puller for a well, including a hollow cone member, means for manipulating the cone member within the well to engage the end of the pipe therein, a collar secured around the upper end of the Cone ico member and having an opening in one side, respect to said openings, and moving parallel Wings formed on the collar at the through said opening. 10 sides of the opening, said Wings being In testimony whereof, I ax my signaformed with longitudinally extending and ture, in the presence of two Witnesses. transversely alnng Series of openings, etV ALBERT F.
