Application tiled April 10,1901. Serial No. 55.162. (No model.)
.To a/ZZ whom t may concern.:
Be it known that I, CHARLES C. HOWELL, of Bradford, McKean county, Pennsylvania, have made certain new and useful Improvements in Oil-Well Flooders, of which the following is a specification.
My invention relates to means for looding an oil-well for the purpose of freeing the walls of the well from the paraffin which collects thereon and which has the effect of lling up the crevices and pores of the oil-producing rock, and thus lessenin-g the yield of the well very materially. I have aimed to provide a simply-constructed device to free the walls of the well from the paraffin wheneverit collects in such quantity as to be detrimental to the yield of the well, and in carrying out my invention I connect with the working barrel of the pumps'a's ordinarily used a section having vents, these vents being closed by spring-pressed valves and opened positively in order to allow the-passage of a vdood of oil discharged into the barrel, the result being that the oil passing to the interior of the well carries away the collection of paraihn.
In the accompanyingY drawings, Figure I is a sectional view of a working barrel, showing the pump within and with my attachmentin place. Fig. 2 is an exterior View of the casing inclosing my attachment; and Fig'. 3 is a plan view looking into the end of the attachment-section, showing the levers carrying the valves.
The working barrel A, anchor 2, of perforated pipe, the check-valve 3, the working valve 4, and the valve-rod 5 are all of the usual or any improved construction. Connected to the upper end of the working barrel is a tubular section B, embodying my improvements. This section is screw-threaded at top and bottom, so as to be capable of ready adjustment, and is strengthened by an'exterior band 6, into which the two parts of the cylinder are secured. Between the two parts of the cylinder a ring 7is held, and this ring carries two springs 8, which engage levers 9, pivoted to the ring 7, and which in turn carry disks lO at their lower ends, serving as valves to close vents l1, formed by nipples passing through the wall of the cylinder B. The levers are formed iiaring at their upper ends, and these ends are curved laterally as well as longitudinally, forming a contracted space between them, through which the pum p-rod passes. In order to ma- 5 5 nipulate the levers 9 to open the vents, I attach to the pump-rod a conical projection 12, which when it is forced down into the opening formed between the flaring ends of the levers 9 forces the upper ends of the levers 6o inwardly against the pressure of the spring 8, with the result that the lower ends of the levers 9 are thrown out and the vents are opened. A discharge of oil may then take place from the oil-tank, and this passes out 6 5 through the vents, removing from the walls of the well the accumulated paraffin. As from ten to twelve barrels of oil is allowed to flow with great force onto the face of the oilrock, it will be readily seen that it will be 7o washed clean. After the washing action the pump-rod is raised and connected with the pitman of the walking-beam and the pumping operation proceeded with with but very little delay and with no wasting, as of course 7 5` the oil used to clean the walls of the well is all pumped back again.
In order not to interfere with the passage of the oil, the projection I2 may be provided with passages or corrugated.
I do not limit myself to any particular kind of pump, valve, or rod, as my invention consists in the interposed section provided with the vents and having valves covering the same, with means for controlling the valves. 85
What I claim is- In combination, the pump-barrel having a vent for the escape ot' iiuid to wash the walls of the well, a valve closing said vent, a lever extending longitudinally of the pump-barrel 9o carrying the valve at its lower end, said 1ever being pivoted intermediate of its length and having a free upper end extendingiinto the path of the pump-rod, the pump-rod, a projection thereon to engage the upper end 95 of the valve-lever to open the valve, and means for pressing the valves normally closed, said means consisting of leaf-springs arranged longitudinally of the .pump-barrel and located between the upper ends of the valveroo levers and the wall of the pump-barrel, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
l CHARLES O. HOWELL.
