STRAINER.
Application mea May as, 1921. serial No. 473,526.
strainers, particularly to a -strainer of the type commonly employed for preventing the entrance of dirt into the carburetor of an automobile. v
The primary object of the invention isto provide a strainer which may be cleaned without being taken apart. r y
Another Objectis to provide av strainer which will be simple and practical in construction, strong, ydurable and eflicient in use, and comparatively inexpensive to manufacture.
With these and other objects in view, the invention consists in certain novel features of construction and combinations andarrangements of parts as will be more fully hereinafter ldescribed and pointed out in the claims.
In the accompanying drawings Figure 1 is a view mainly in longitudinal section, but partly in elevation illustrating the interior construction of my improved strainer; and A n Figure 2 is an enlarged view in transverse section on the line 2 2 of Figure 1. f
Referring in detail to the drawings, 1 represents a cylinder, which is interposed between a pair of castings 2 and 3. Both of the castings are provided with annular flanges 4 embracing the cylinder and gaskets 5 are located between the ends of the cylinder and the castings. The castings are providedwith radiallyextend ing aligned perforated lugs 6. Bolts 7 passed through the lugs and nuts 8 around the bolts serve to clamp the cylinder 1 firmly between the two castings.
The lower casting 3 is provided with a threaded opening 9, which receives the threaded end of an inlet pipe 10. The inlet pipe 10 enter-s the side of the lower casting 8 and a drain pipe 11 is screwed into the'bottom of the casting 3 and is controlled by a pet cock 12. The pipe 11 serves as a trap for dirt.
An outlet pipe 13 enters the cast#l ing 2 at a point diametrically `opposite the pipe 10. The casting 2 includes `an upwardly extending externallyv threaded hollow .post 14 and an internal-ly threaded cap. 415 serves to clamp graphite packing or a similar substance 16 against thetop of the post 14. The cap 15 Vis provided with an,y
Parar ortica. i
opening 17 registering with the hollow post l and a'plunger rodlis movable through the post and cap. It will be readily seen .that
by screwing the cap 15 more tightly down` upon the post 14, the packing materiall 16- will be` compressed and the friction between, the plunger rod 18 and the packing-mate-. 7
rial will be increased. n
19 represents an v annular member slidable vertically in the cylinder 1 and lgrooved" `to receive a packing ring 20 which engages the inner walls of the cylinder. This annular -member 19 is formed with an integral transverse web 21 to which the lower end of the plunger rod is attached. A screen 22 of fine wire gauze isv soldered across the lower end of the member 19. This member 19 together with the screen 22 forms in effect a piston, and any approved handle member designated by the reference numeral 23 may be secured to the upper end of the plunger rod 18, for manually recipro-` ating the plunger or piston in the cyliner 1.
The method of use of the strainer will be apparent. Gasoline under pressure is introduced into the pipe 10, passed through the strainer 22 and out through the pipe 13. When'it is desired to clean the strainer 22, the pressure in the pipe 10 is cut off and the cylinder 1 is left full of gasoline. By
manually reciprocating the screen back and forth, the gasoline in the cylinder will wash the dirt from the screen and the dirt will This dirtyy gasoline may then be n i ico consider myself at liberty to make such discharging the liqui slight changes and alterations as fairly fall within the spirit and scope of the appended claims. 1 e
1. A fluid`v strainer comprising a cyllindricalbody, a head at the lower end provided with an inlet and a drain, a head at the upper end provided with an outlet, and
a strainer element mounted in said body and having exteriorly disposed means Jfor eiecting reciprocations of the" strainer between the. opposite ends of the body forI the purpose of cleansing the same by' its movementV through the liquid trapped in the body.
2A` fluid strainer comprising a cylindrical body, ya head `at the lower end having an inlet and adrain cock, a head at the upper end provided with. an outlet, a strainer element mounted in the bodyv for reciprocations between its opposite ends,
cluding a pair of castings, a cylinder, flanges on the castings embracing opposite ends of the cylinder, means clamping the cylinder between the castings, an inlet pipe communicating with the lower casting,y an outlet pipe communicating with the upper casting,
a ring shaped member slidable vertically in the cylinder, a screen secured across the ring shaped member, a plunger rod operatively connected'to the ring shaped member, a hollow post integral with the upper casting and ,guiding the movement of the plunger rod.
4. A device of thev character described, in-
cluding a pair of castings, a cylinder, flanges on the castings: embracing opposite ends vof the cylinder, means clamping the cylinder between the castings, an inlet pipe commu- .nicating with the lower casting, an outlet pipe communicating with the upper casting, a ring shaped member' slidable vertically in the cylinder, a screen secured Aacross the ring shaped member, a plunger rod operatively connected to the ring shaped member, a hollow post, integral with the upper casting and guiding the movement] of" the plunger rod, and means associated with'the hollow post for regulating the :friction on the plunger rod.
