OF PAPILLION, NEBRASKA,

ROD-FULLER.

Specification of Letters Patent.

Patented June 13, 1911.

Application filed October 13, 1310. Serial No. 586,923.

To allwhom it may concern:

Be it known that I, GUY L.'HORN, a citizen of the United States, residing at Papillion in the county of Sarpy and State of Nebraska have invented certain new and useful Improvements in Rod-Pullers, of which the following is a specification reference being had therein to the accompanying drawing.

This invention relates to rod pullers and the principal object of the same is to provide a means whereby a rod may be withdrawn from a pipe after it has been broken or become detached.

It often happens that the wooden") rod breaks at a great distance in the pipe and it is impossible to remove the lower portion, thus necessitating the abandonment of the well and a greatloss in time and money. This invention makes it possible to with draw the lower portion.

The invention is illustrated in the accompanying drawings wherein:

Figure 1 is a perspective view of the improved rod puller. Fig. 2 is a perspective view of the improved rod puller taken from a difi'erent angle to Fig. 1. Fig. 3 is a vertical sectional view along the line A.-A in Fig. 1. Fig. l is a transverse-sectional view along the line 12-6 of Fig. 1.

The improved rod puller comprises a bar 1 which is formed from 5 ring steel and in the preferred form is ma e rectangular, but which can. he of any shape desired. One end of the bar is rounded and provided with an external thread as shown at 2. A collar 3 is threaded upon the thread portion 2 and is used to connect the rod puller to an operating rod 4. The other end of the rod is rolled flat and coiled to form a hollow tapering sleeve 5 the edges of which pverlap as shown at 6 but which are not welded or otherwise secured together. The sleeve is provided with a circular opening at its lower end the edge of which is beveled on its inner surface as indicated by the number 7. The

into opening in the upper end is elongated and substantially V-shaped as indicated by the numeral 8 and its edge is beveled upon its outer surface as .indicated by the numeral 9 thus forming a knife edge.

The upper portion of the sleeve is outwardly beveled as indicated by the numeral 10 to guide the end of the broken rod through the opening 8.

From an inspection of Figs. 2 and 3 it will be seen that the sleeve is bent to one side so as to bring the lower edge of the opening 8 on a line with the face of the bar 1 and so that a line drawn along the center of the bar 1 will pass throughthe center of the sleeve.

The operation of the device is as follows :-When a wooden rod breaks, the upper portion is withdrawn and the rod puller inserted into the pipe. used which is about one-fourth of an inch smaller than the diameter of the pipe so that there will be no danger of the broken end getting between the sleeve and the side of the pipe. The puller is lowered into the ipe until it comes in contact with the rod and the sleeve is then forced over the end so that the rod passes through the sleeve and comes out through the opening 8. By. hav ing the

beveled portions

7 and 10 the rod enters the sleeve easier and is guided out through the opening 8. The sleeve being made of spring steel and having its edges unconnected it can, tightly grasp the rod as the rod expands it slightly. By having the outer edges of the opening 8 beveled the rod is prevented from coming out when the puller is drawn u as the knife edges cut the rod and tightly hold it. It should also be noted that the sleeve is made tapering and that the farther the sleeve is forced upon the rod, the tighter it will grip the same.

It should be noted that by having the edges of the upper opening fiush'with the face of the rod that the broken rod isslightly bent in order to pass out through" the upper A puller should be opening. By having the rod bent the sharp edges ofthe sleeve can better engage the rod so as to bite into the same.

What I claim is 1. A rod puller comprising a bar, and a sleeve at one end of said bar having free edges overlapped, the upper edge of said sleeve being sharpened.

2. A rod puller comprising a bar, a sleeve 10 at one end of said bar, said sleeve being provided with top and bottom openings, said top opening being substantially V-shaped and having its edges beveled upon the outer surface.

In testimony whereof I hereunto aflix my 15 signature in presence of two witnesses.
