- I '0 all whom it may concern:
' ing the sand together with means for caus- Be it known that I, OscAR R. Krnsonxn, a citizen of the United States, and a resident of Grand Island, in the county of Hall and State of Nebraska, have invented certain new :and useful Improvements in Sandlstrainers, of which the following is a specification.
My invention is an improvement in sand strainers, and has for its object to provide mechanism of the character specified for use in connection with well casings for thoroughly removing sand from the water before it enters the body of the well casing, the strainer having a sand chamber between the bore thereof and the exterior for receiving the sand to settle.
In the drawings Figure 1 is a side view of he improved strainer, i
Fig. 2 is a top plan view,
Fig. 3 is an enlarged partial longitudinal section,
Fig. 4. is an enlarged side view,
Fig. 5 is a detail section of a portion of the strainer,
In the present embodiment of the invention, the strainer is composed of a series of similar sections each section 1 having one end annularly rabbeted externally as at 2, and the other end annularly counterbored or reamed as at 3, to receive the rabbeted end of the adjacent section; Each section is also. provided in its wall with aseries of longitudinally extending passages 4, which are sand chambers for receiving the sand, and the said passages or chambers extend the full depth of the section.
Series of slots.5 and 6 are provided in the sections, extending longitudinally thereof, the said slots being parallel and spaced apart from each other, and preferably the slots of each series are arranged in groups of three, as clearly shown in Fig. 1.. .Each'series of slots is separated by an annular imperforate portion'as shown in Fig. 1, and the slots 5 are intermediate the ends, of the section, while the slots 6 are at the ends of the sections, and open at the ends.
Each group of three slots opens into one passage or sand chamber 4,?and the reduced or rabbeted portion7 of each section has a series of vertical grooves or flutes 8, which open by lateral grooves .or recesses 9 into the sand chambers, the said grooves 9 being formed on the annular shoulder between the rabbeted portion and the body of the sec= tion. The rabbeted portion of each section is of slightly less length than the counterbored portion of the section, so that when the reduced end of one section is fitted into the counterbored end of the other section there will be a space, indicated at 10 in Fig. 3, between the annular shoulder formed at the inner end of the ream or counterbore and the reduced end of the section. This spaced end provides a communication between the upper ends of the grooves 8 and the interior of the strainer, while the grooves 9 provide communication between the lower ends of the grooves 8 and the sand chambers.
Thus when the sections are placed, it will be seen that passages lead from the sand chambers inwardly and upwardly and again inwardly to the bore of the well casing. so that the water is constrained to rise during its passage from the sand chamber to the bore of the casing.
I claim 1. A sand strainer for attachment to well casings, comprising similar sections, each having one end counter-bored and the other end reduced to enter the counter-bored end ot the adjacent section, each section having a series of vertical sand passages in its walls and being slotted externally at each passage, and having passages leading from the sand passages to the interior of the casing and extending upwardly from the sand passages to the interior of the casing, said last named passages being formed between the counterbored surface and the outer face of the reduced portion, and between the end of the reduced portion and the annular shoulder formed at the inner end of the counter-bored portion of adjacent sections.
2. A sand strainer for use with well casings, comprising a' series of sections, each having one end reduced and the other end 'counter-bpred to receive the reduced end of the adjacent section, said sections having longitudinally extending sand passages/in their walls and opening externally, and hav- 7 ing passages leading'from the sand passages to the interior of the sections and upwardly from the sand passages.
3. A sand strainerfor use with well cas ings, comprising a cylindrical structure hav-?.'.
ing longitudinally extending sand passages in its wallopenmg externally and having other passages leading from the sand passages inwardly and upwardly to the interior of the casing.
4. A sand strainer for use with well casings, comprising a hollow structure having longitudinally extending sand passages in its wall opening externally and having other passages leading from the sand passages inwardly and upwardly to the interior of the casing.
5. A sand strainer for use with well casings, comprising a hollow structure having longitudinally extending sand passages in its wall opening externally and having other passages leading from the sand passages inwardly t0 the interior of the casing.
6. A sand strainer for use with well casings comprising a hollow structure having sand passages in its wall opening externally and having means for constraining the water to pass upwardly from the sand pas- 20 sages before entering the strainer.
