PHILIP C. EMANUEL, OF IBENNET'ISVILLE, SOUTH CAROLINA.
DEVICE FOR PULLING PUMP-PIPES.
Specification of Letters Patent.
Patented Apr. 4, 1911.
Application filed May 31, 1910. Serial No. 564,207.
To all whom it may concern:
Be it known that I, PHILIP C. EMANUEL, a citizen of the United States, residing at Bennettsville, in the county of Marlboro and State of South Carolina, have invented a new and useful Device for Pulling Pump- Pipes, of which the following is a specification.
The invention relates to a device for pulling pump pipes.
The object of the present invention is to provide a simple, inexpensive and. eflicient device of great strength and durability, designed for pulling out of the ground driven pump pipes when it becomes necessary to remove the same for renewing the point or screen, or for any other purpose, and adapted to be operated by hand at the surface of the ground, and capable of enabling a pump pipe to be easily removed in sections without liability of crushing or otherwise damaging the pump pipe.
With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that va-- rious changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invenvtion.
In the drawing :Figure 1 is a vertical sectional view, partly in elevation, of a pump pipe pulling device, constructed in accordance with this invention. Fig. 2 is a transverse sectional view of the upper portion of the device. Fig. 3 is a horizontal sectional view of the same. Fig. 4 is a reverse plan view ofa portion of the operating lever. Fig. 5 is a detail sectional view, illustrating the manner of mounting the dogs or catches. Fig. 6 is a detail perspective view of an extension section of the tubular shield.
Like numerals of reference designate corresponding parts in all the figures of the drawing.
In the embodiment of the invention illustrated in the accompanying drawing, 1 designates a tubular shield, surrounding the upper portion of the pump pipe 2, and equipped at opposite sides with laterally projecting lugs 3, arranged in pairs and adapted to be engaged by dogs or catches 41, carried by a cross head 5, which is operated by a lever 6. The tubular shield, which surrounds the pump pipe, is adapted to prevent the same from being crushed or otherwise damaged in. pulling the same from the ground, and it is provided at its upper end with exterior screw threads 7, engaging interior screw threads 8 of a cap 9. The cap 9, which is fitted on the upper end of the pump pipe, is provided with a socket 10 to receive the upper end of the tubular shield, and it is also provided with a threaded upper counter-bore 11 to engage the threaded upper end 12 of the top section of the pump pipe. Instead, however, of providing a threaded connection between the upper end of the tubular shield and the cap, these parts may be detachably connected in any other preferred manner. The cap is readily uncoupled from the tubular shield and disconnected from the pump pipe to enable the parts to be removed after a sec.- tion of the pump pipe has been pulled out of the ground, as hereinafter more fully explained. The pump pipe is pulled from the ground in sections, and as soon as one section thereof is clear of the ground, it is uncoupled and the device is connected with the next section of the pump pipe.
The lugs 3 are beveled at their outer edges and are shouldered at their lower edges, and the opposite catches 4Z-engage the lower edges of the lugs when the lifting arm or portion of the lever is raised, and are adapted to slide over the lugs when the lifting portion of the lever is lowered to engage the catches with another set of lugs.
The cross head 5 is composed of a pair of metallic bars 13, spaced apart by metallic blocks or pieces 14:, interposed between the end portions of the bars 13, which are provided with oppositely bowed intermediate portions 15, forming an opening to receive the shield. The end portions of the bars 13 are preferably straight and are bolted, or otherwise secured to the blocks or pieces 14. The bowed portions 15 of the bars of the cross head receive the tubular shield and are adapted to slide upward and downward thereon, the cross head being held against rotary movement by means of a screw 16, mounted in a threaded opening of one of the bowed portions 15 of the cross head and engaging a vertical longitudinal groove 17, formed in the exterior of the tubular shield 1. The screw is also adapted to clamp the cross head to the shield, when it is desired to support the same and the pipe in an elevated position.
The dogs or catches 4 have rounded lower ends and are inclined upwardly and inwardly, being maintained in engagement with the tubular shield by means of springs 18; The blocks or pieces are provided with curved seats 19 to support the lower rounded ends of the dogs or catches, which are secured to the cross head by bolts 20, piercing the side bars 18. The curved seats sustain the dogs or catches and relieve the bolts of strain. The springs 18, which are curved, are secured by screws, or other suitable fastening means to the upper faces or edges of the blocks or pieces 14L at the inner ends thereof. c
The lever 6 is preferably constructed of wood, the other parts of the apparatus being made of suitable metal, but a metallic lever may be employed if desired. The front engaging end of the lever is provided with a recess 21 to enable it to fit around the tubular shield, and it is reinforced by a metallic plate or piece 22, secured by bolts 23 to the lever. The bolts also fasten a bottom plate 2i to the lower face of the operating lever. The bottom plate 24 is provided with a plurality of integral depending ears 25, adapted to receive a pivot bolt 26 for connecting the lever to spaced sides 27 of a bracket 28, mounted on a block 29 and forming a fulcrum of the lever. The block 29 is preferably constructed of wood, and the bracket 28 is provided with a depending shank 30 embedded 'in the block, shown. The fulcrum is shiftable or adjustable along the lever to vary therel'ative lengths of the arms thereof to enable the lever to exert great power in withdrawing a pump pipe and also to be arranged for increasing the stroke of the lever and lifting the pipe when great leverage is not required for pulling the same from the ground.
In applying the apparatus toa pump pipe, the earth is dug from around the pipe to permit the tubular shield to be placed thereon. In pulling a pump pipe out of the ground, .the lever is operated to engage the catches with the top set of lugs, and the pipe is pulled the distance of one stroke of the lever. The catches are then engaged with the nextset of lugs, and the pulling operation is repeated 'until the pipe has been lifted the length of the tubular shield. If this is insuflicient to lift one of the sections of the pump pipe clear of the ground, an extension section 31 is connected to the upper end of the shield 1 and to the cap 9, and the device is again operated to pull the pipe. The exte nsien section 31 is threaded at is upper end 32 to screw into the cap, and it is equipped at its lower end with a coupling 33 to screw on the upper end of the shield. As the ex tension tube 31 is applied to the upper end of the shield 1, the latter remains in position to co-act with the operating lever and consequent-1y it is unnecessary to equip the extension tube with the lugs 3.
While only one tubular extension section is shown in the drawing, in practice the device will be equipped with sections of different lengths to enable it to be arranged to suit the length of the sections of the pump pipe operated on.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
