PUMP-ROD SHOE;
mesma.
To all 'whom it may concern:
citizen of. the United States, residing at Pomona, in the county of Los Angeles, State of California, have invented a new and useful Pump-Rod Shoe, of which the following is a specification.
This-invention relates to pumps and particularly to those in which the pumping means is located at, or near the bottom of a well, being actuated through pump rods by a suitable pumping head located at the surface of the ground. In the usual form of such pumps the pump rods are in tension when performing work and tend to assume a straight line. In deep Wells there are often bends inthe pump column so that the pump rods tend to rub on the pump column, thereby abrading both the pump rods and the pump column.
The principal object of my invention is to provide means for reducing this abrasion to a minimum.
Further objects and advantages will appear hereinafter.
Referring to the drawings which are for: illustrative purposes only.: Figure 1 isan elevation, partly in section of my invention applied to a deep well. Fig. 2 is a section on the plane t2- x2 of Fig. 1. Fig. 3 is a perspective view of the shoe employed in my invention.
In these drawings a well casing 10 is driven vertically in the ground and a pump column 11 is placed therein, the pump barrel in which the piston works being in open communication with the interior of the pump column 11, the fluid to be pumped being raised vertically through this pump column. Pump rods 12 and 13 pass upwardly through the pump column 11 and connect the piston with thepumping head which is placed on the top of the ground. The pump rods 12 and 13 are connected by a threaded coupling 14.
The well casing 10 is often bent out of line due to various causes. The best practice in drilling water wells is to sink a square shaft to water level, removing all boulders. The well casing'is then supported in a vertical line in this shaft, loose material being filled in around it. The well `below water line is. then drilled, and the casing is forcedvdownwardly generally by means of hydraulic jacks.
Specification o f Letters Patent.

Application led September 9, 1914. Serial No. 860,935.
In drilling through soft material large stones, such as that illustrated at 15, may be located on the line of the drill which will be considerably deflected thereby. As the well casing falls the line of the drill may be considerably deflected as illustrated, the pump column 11 being similarly. deflected. The pump rods tend to assume a straight line, being flexible and under a considerable tension, and where the pump column has been deflected the coupling 14 will tend to r'ub on the side of the pump column. This tends to wear holes in the'pump column and also to wear oif the coupling` 14 as will readily be understood, particularly as the coupling is of small diameter as compared to the pump column and the line of contact between the Coupling and the vcolumn .is a narrow line under considerable pressure.
For the purpose of distributing the pressure of the pump rods 12 and 13 over a wide area on the interior of the pump column I pro- -vide a shoe 16 which has a central opening 17, large enough to fit loosely over the pump rods 12 and 13, and openings 18 at either side thereof, these openings being added for the purpose of increasing the effective area through which. the rising stream of water may ow. The 'shoe 16 is illustrated as placed over the rod 12, a collar 19 being shrunk on the pump rod 12 above the shoe 16, the distance between the collarl 19 and the coupling 14: being just suiiicient to allow the shoe to turn freely without sliding axially. The sides of the shoe 16-are made on the same radius as the interior of the pump column so that the shoe 16 bears evenly over alarge bearing area, the shoe being made considerably longer than the coupling.
The result of applying my invention to the pump rods of a Well having a crooked' pump column is that when the rods 12 and 13 are reciprocated vertically the shoe 16 provides a large bearing area against the interior of the column so that the wearing of the column and shoe becomes negligible and the well may be pumped for long periods without'danger of perforating the pump column.
I claim as my invention:
1. In a well, a pump column, a series of pump rods reciprocated vertically in said column, and a series of shoes having sides curved to it the inside of the pump column,
said shoes being loosely secured to` said- 2. In a Well, a pump column, a series of pump rods reciprocated vertically in said column, and a `series of shoes having sides curved to fit the inside of the pump column, said shoes being secured on saidpump rods in such a manner that they move with said pump rods and adjust themselves about the axis of said pump rods to suit the position of said column. y j
3. In a'well, a pump column, a series of pump rods reciprocated vertically in said column, a series of couplings each connecting a pair of said pipe rods,.a collar shrunk on each of said pipe rods, and a shoe having its sides curved to fit the inside of said pump column, said shoes being loosely mounted between each of saidcollars and its corresponding coupling.
Lilia??? v shoe is free to'turn about the axis of said pump rods but is restrained from moving along this axis.
In testimony whereof, I have hereunto set my hand at Pomona, California, this 27th dayof Aug., 1914.
