STRAINING PRIMER'FQR PUMPS.
- Application and 'August so; '1924. serial No.' 735,067.
This invention relates to an impro-ved straining primer or combined strainer and primer for pumps, its main object being the production of a device' of this character which is simple, compact, inexpensive, easily cleaned, and highly eilicientfor removing foreign matter With this and other objects not specifically mentioned in view, the invention consists 0 in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.
In the accompanying drawings which part of thisspecification and in which like characters of reference indicate the same or like parts, Fig. 1 is a sectional elevation of a device constructed in accordance with the invention, and Fig. 2 is an inerted planview taken on the line 2-2 in In carrying the inventioninto effect, there is provided a casing having intake and outlet ports near its top in order to retain a body of liquid within the casing at all times for pump priming purposes, said casing being adapted to be connected in the suction pipe line adjacent a pump. This casing is further provided with an apertured wall interior into an intake chamber 1n communication with said intake port and an outlet chamber in communication with said outlet port, and a straining device is located in the path of liquid flow from said intake chamber through said apertured wall to said outlet chamber and thence through said outlet port. These parts may he varied in construction within the scope of the claims, for theparticular device selected to illustrate the invention is but one of numerous possible concrete embodiments of the invention. The invention, therefore, isnot to be restricted to the precise details of the structure shown and described.
Referring tothe drawings, 3 indicates a `casing which is provided with a cover 4 normally closing the top of said casing. The ca'sing 3 has an intake port 5 'and an outlet i port 6, both being located near its top and diametrically opposite each other. The intake port 5 is in communication with an intake chamber 7, and the outlet port 6 is in communication with an outlet chamber 8, the latter extending across the bottom of the dividing from the liquid pumped chamber 7 and up one of its sides. The casing is provided with, an lapertured` wall its interior into these'two Achambers, and this wall is apertured at 9,- at the 4bottom of the chamber?. v
The flowo'the liquid when the device is in operation is through the intake port 5 to the chamber 7, thence through the apertured wall at y9 tothe chamber-8, and thence rout through the outlet port 6. To arrest foreign matter carried into the device by the flowing liquid, there is provided a strainer in the pathofthe flowing liquid from the intake chamber through the apertured wall to the outlet chamber, and as shown this strainer is cylindrical in form as at l0 and is interposed between the bottom of the intake chamber 7 and the cover 4. It is of a diameter approximately the same as the diameter of the aperture at 9 of the dividing wall in the casing. a p For the purpose of collecting foreign matter separated from the flowing liquid passing. through the strainer 10, there isprovided an annular receptacle for said matter which is marked 11 and which is secured to the strainer 10 so that upon removal of the cover 4 the strainer and receptacle may be removed from the casing together for cleanlng purposes. It will be noted that although the device is compact the effective area of the strainer is very large with respect to the area of the intake and outlet ports. It therefore offers but slight resistance to the action of the pump. Moreover, it will need cleaning only at infrequent intervals unless the liquid pumped is exceptionally dirty. It will also be not-ed that since the device is always full of liquid to the level ofthe intake and outlet' ports, this liquid is always available for rimmfr ur oses. In other words water is entrapped in the intake fand outlet chambers if, by reason of pump stoppage, the water in the pipe line connected with the intake port 5 runs back to the source of supply. When the pump is again started, it first acts upon this entrapped water which primes and seals it sopthat it will suck the air from the pipe line connected with the intake'port-5, followed of course by the water flowing into said pipe line when a partial vacuum is set up therein.
For the purpose of permitting drainage ofthe outlet chamber if desired there is provided a threaded .plug 12 in die botten; of the casin 3. Y
When t e device is in operation, the liquid v being pumped flows through the intake port to the annular spiace surrounding the strainer 10,V thence t rough sai'd strainer, thence through the aperture 9 of the vdividing wall into the outlet chamber `8 Aand f rounding the strainer.
What is claimed is:
1. A straining primer for pumps comprising a casing having intake and outlet ports near its to vand provided with an apertured wall divi ingvits interior into. anintake chamber in communication wthsaid intake port and an outlet chamber-in communication with said outlet port,- a removable cylindrical strainer interposed between the Ltop and bottom of said intake chamber in the r throug said apertured wall to said outlet'chamber, and an annular receptacle for foreign matter surrounding and secured to and removable with said strainer.
2. A straining primer for pumps comprising a casing havmg'intake and outlet ports near itsl to and provided with an apertured wall 'divi ing its yinterior into an intake chamberin vcommunication with said intake port and an outlet chamber in communication with said' outlet port, a cover normally closing the top of said casing, a cylindrical strainer interposed between said cover and thebottom of said intake chamber in the path of liquid flow from said intake chamber through said apertured'wall to said outlet chamber, and an annular receptacle for foreign vmatter surrounding and secured to said strainer and removable withfsai'd strainer when said: cover is removed.
In testimony-whereof, I have signed my name to this specification.
