Application ined July 1, 191e. serial No. 107,123.
This invention relates to certain improve.
ments in strainers for pumps and has relation more particularly toa device ofV this general character especially designed and adapted for use in connection with oil wells or the like; and it is an object of the invention to provide a novel and improved strainer adapted to be engaged with the lower end of the working barrel of a pump and through which the oil is adaptedto be drawn, and which serves to effectively separate sand or the like from the oil as itpasses therethrough.
Furthermore it is an object of the invention to provide a novel and im roved strainer of this general character having its lower end portion provided with a removable collecting member at the lower end thereof. and into which is adapted to drop the sand or the like which may pass Within the strainer.
The invention also has for4 an object to provide a novel and improved device of this general character which may be assembled with convenience and facility and wherein the several parts comprised therein may be easily removed when the requirements of practice may so necessitate.
The invention consists in the details. of construction andin the combination and arrangement of the several parts of my improved strainer whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.v
The novel features of the invention will hereinafter be definitely claimed.
In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompaitying drawings, wherein- Figure l is a longitudinal sectional view taken through a strainer constructed in accordance with an embodiment of my invention;
Fig. 2 is a plan view of the intermediate annularmember aspherein employed; and
Fig. 3 is a plan view of one ing members" herein embodied.
As herein embodied, my improved strainer comprises an elongated tubular member 1 of predetermined dimensions and having its intermediate portion provided with the restricted openings or -perforations 2, while the opposite ends thereof are provided with the peripheral threads 3 with which are adapted to be engaged the unions 4 substantially bellshaped in form with their larger ends disposed inwardly and provided with the annularperipheral grooves 5 for a purpose to be hereinafter more fully set.
forth.
The end portion 6 of the unions 4 extend beyond the adjacent ends of the tubular member 1 and the upper extended portion 6 is adapted to have detachably engaged therewith the connecting pipe 7 which is also adapted to be detachably engaged with the lower end of the working barrel B. The extended portion 6 of the lower union 4 has detachably engaged therewith the imperforate p ipe section 8 of predetermined length and which has its lower end closed by the removable cap 9.
The pipe section 8 serves as a collecting member and is adapted to receive the fine particles of sand or other material which may pass within the member 1 through the openings 2 thereof.
Suitably secured to the member 1 at substantially its longitudinal center is the outstanding annular member 10 provided with the openings 11 for a purpose which is believed-.to be self-eviden 12 denotes a perforate cylinder preferably comprising a sheet of reticulated ma terial and which is surrounded by the sheet 14 of fabric preferably burlap, and said sheet 14 is held in operative position relative to the cylinder 12 through the medium of the outer perforate cylinder 15 herein disclosed as comprising asheet of reticulated material of a materially larger mesh than the mesh of the-first named cylinder l2.
The ends of the cylinders 12 and 15 and the intermediate sheet 14 overlie the annular grooves 5 of the unions 4 and have coacting therewith the clamping members 16, whereby said cylinders 12 and 15 and intermediate sheet 14 are effectively secured in applied position.
of the clamp- The annular' member 10 serves to maintain the intermediate portion of the cylinder 12 in spaced relation relative to the member 1 and the periphery of said annular member is provided with the groove 17 to facilitate the coaction of the clamping member 18 for further assuring the maintenance of the cylinders 12 and 15 and intermediate sheet 14 in applied position.
It will be perceived that as the oil is drawn through the perforations 2 into the member 1, the cylinder 12 together with the sheet 14 serve to separate from the oil sand or lkindred substances.
From the foregoing description, it is thought to be obvious that a strainer constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification 'Without material departure from the principles'and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my in'- ventiQn in practice, except as hereinafter claimed.
I claim:
1. A strainer of the character described comprising an elongated hollow member having its intermediate portion provided with perforations, unions engaged with the opposite ends of the member, the inner ends of the unions being of a diameter materially in excess ofthe diameter of the hollow member, and a pervious cylinder interposed between the unions and engaged therewith.
2. A strainer of the character described comprising an elongated hollow member having its intermediate .portion provided with perforations, unions engaged with the opposite ends of the member, the inner ends of the unions being of a diameter materially in excess of the diameter of the hollow member, a pervious cylinder interposed between the unions and engaged therewith, and an annular member secured to the tubular member at a point intermediate the length thereofand affording a support for the intermediate portion of the pervious cylinder.
3, A strainer of the character described comprising an elongated hollow member having its intermediate portion provided wlth perforations, unions engaged with the opposite ends of the member, the inner ends of the unions being of a diameter materially in excess of rtheffia'meter of the hollow member-,7a pervious cylinder interposed between the unions and engaged..J ewith, an annular member secured to the' tubular member at a point intermediate the length thereof and aording a support for the intermediate portion of the pervious cylinder, and means for clamping the pervious 'cylinder to the annular member.
4. A strainer of the character described comprising an elongated hollow member having `its intermediate portion provided with perforations, unions engaged with the opposite ends of the member, the inner ends l of tlTeunns being of a diameter materially in excess of the diameter of the hollow member, a pervious cylinder interposed between the unions and engaged therewith, and a collecting member removably engaged with one of the unions.
5. A strainer of the character described comprising an elongated hollow member having its intermediate portion provided with perforations, unions engaged with the opposite ends of the member, the inner ends of the unions being of a diameter materially in excessil of the diameter of the hollow.member, a pervious cylinder interposed between the unions and engaged therewith, and a member secured to the tubular member at a point intermediate the length thereof and a ording a support for the intermediate portion of the pervious cylinder.
In testimony whereof I hereunto affix my signature in the presence of two witnesses.
