LOUIS H. KNIPPER Patented Dec. 6, 1949 UNITED STATES ATENT OFFICE 1 Claim. 1
This invention relates to a filter, one that can operate in a horizontal or vertical position direction independently and can be used with pumps and other similar types of machinery used with water, oil, or other liquids.
An object of the invention is to provide a device that avoids clogging of the device as well as preventing foreign objects `from passing into the pumps and causing wear on vital parts.
Another object of the invention is to provide a device that will operate from the topl thereof while the bottom remains inactive.
A further object of the invention is to provide v a device that is inexpensive to manufacture, easy to assemble, and efficient in operation.
With these and other objects and advantages in view the invention comprises certain novel combinations, constructions and arrangements of parts aswill be hereinafter described, illustrated in the accompanying drawings and more particularly pointed out in the appended claim.
In the drawings:
Fig. 1 is a side elevation of an embodiment of the invention.
Fig. 2 is an end view thereof.
Fig. 3 is a sectional view on the line 3-3 of Fig. l.
Fig. 4 is a modification of the coupling means of the device.
Fig. 5 is a sectional view thereof.
Fig. 6 is a detailed view of the screen holding rod.
Fig. 'l is an end View thereof.
Fig. 8 is a sectional View on the line 8-8 of Fig. 5 and,
Fig. 9 is a sectional View on the line 9-9 of Fig. 5.
Referring more in detail to the drawings the numeral l!) designates the tubular casing or body of the lter which can be made of sheet metal, bar stock, or a suitable thermosetting plastic, as stated the body it is tubular open at the end l2 and closed at the end I Il.
In Fig. l, the open end l2 is externally threaded for the reception of a pump suction tube, or for connection to any other type of machinery with which the lter is to be used.
The casing il) is provided near the threaded portion of the end l2 with a shoulder i6 that can be round, square, or hexagonal for the reception oi a wrench or 'other tool for the purpose of tightening the lter when connections are being made.
One side of the casing li! is provided with perforations or openings I3.
'ill
These openings I8 act as intakes for the liquid to be ltered and can be set in any position to suit the conditions of the liquid and the foreign objects involved.
The openings are positioned in parallel rows and in relatively spaced staggered relation to each other.
A circular mesh screen 2li having the ends thereof cleated in circular collars 22 is positioned on the casing il! and is retained thereon by means ci screws 24. The mesh perforations can be of a size suitable to the conditions existing at the time the filter is to be used.
The screen 20 is of a suiicient length to entirely cover the rows of openings I8 in the casing lil.
A circular inner mesh screen 25 having a rounded nose or end 23 and an open end 29 is positioned in 'the casing il). This screen is preferably made of brass, but can be made of any other non-corrosive material, and perforations in this screen will be of a size suitable for the prevailing conditions at the time the filter is to be used.
The diameter of the screen 2S is of a slightly smaller diameter than the internal diameter of the casing l0 thus permitting suicient space between the screen 26 and casing Il! to prevent clogging of the screen.
The screen 26 is retained in position in the casing It by means of a circular band or collar 30 which is secured to the open end 29 of the screen 26 and a rod 32.
The band 30 has an outer circumference of a suilicient diameter to slidably iit in the inner circumference of the casing Il).
The rod 32 has a head 34 positioned Within and conforming to the rounded end 28 and passes through an opening 3S provided in the end 28 of the screen 25. The rod 32 passes through an opening 38 in the closed end Ill of the casing il).
The end of the rod is threaded and extends beyond the end of the casing lll to receive a complementary threaded nut 4B. In this fashion the screen 26 is properly positioned and retained in the casing l0.
The space il thus provided by the length of the rod 32 acts as a trap for small foreign objects and will prevent the clogging of the screen 26.
In Fig. 4, is disclosed another method of coupling or connecting the lter to the pump or other machinery with which it is to be used.
In this -instance the end i2 of the casing is provided with a circular groove 42.
The end l2 is received in the socket or sleeve 44 and is retained therein by a set screw 46 which enters the groove 44 and rotatively retains the casing l0 therein, or if the set screw 46 is suiiciently tightened will retain the casing therein in a xed or set position.
The socket 44 can be a part of a pump suction tube 48, or can be made in any other fashion such as internally threaded for connecting the socket 4 4 as desired.
It will be understood, therefore, by those skilled in the art that the embodiment of the invention herein disclosed accomplishes the objects of the invention and provides a device that can be used in a vertical or horizontal position and can use mesh screens having various sizes of-perforations to meet the prevailing conditions existing at the vtime the lter is to be used. It alsoha's other .advantages than those herein particularly referred to, also that various changes and modifications may be made without. departing from the Yspirit of the inventionor `thescope of the Vapings of `said casing, arcircularband of a diameter slightly smaller thanthe inner circumference of said casing slidably fitted in said casing, an inner tubular screen of a diameter slightly smaller than the inner circumference of said band and of a lengthsubstantially less than the nto the closed end of the inner tubular screen at one end and having its other end tln'eadably mounted in the closed end of the casing and pro- ;Vided with a lock nut exteriorly of the closed end ofthe casing.
