Application led October 23, 1925.
This invention relates to improvements in strainers and more particularly to a'type especially adapted for filtering gasoline or the like where it is desired to remove all particles of sediment and water.
One of the objects of the present invention is to provide a simple and practical strainer comprising relatively few parts which may be inexpensively manufactured and assemoled.
A further object is to provide a portable strainer of the above general character which may be easily taken apart for cleaning and whereby the interior parts may be removed permitting` the outer portion to be used as a container or funnel.
A further object is to provide a strainer of the above general character which will be strong and durable and not require the frequent replacementof parts as with strainers now in general use7 for example, by actual test it has been proven that the time consumed in refueling `an airplane with this improved filter has been reduced to onethird of the time required with the use of the commonly used chamois skin filter. The use of chamois skin not only makes refueling a long and tedious. task7 requiring time and patience, but causes the increased hazard of fire by the constant danger of the generation of static electricity. The chamois skin soon becomes harde-ned and thereby loses its effectiveness and necessitates constant renewal.
Other objects will be in part obvious and in part hereinafter pointed out in connection with the accompanyiner sheet of drawings illustrating one of Various embodiments of the invention and in the several views of which corresponding parts are indicated by similar reference characters.
In these drawings,
Figure 1 is a vertical longitudinal section of the device embodying features ofv the present invention.
Figure 2 is a sectional view taken substantially on the line 2/2 of Figure 1.
Referring now to the drawings in detail and more particularly to Figure l, the embodiments hereinafter described comprise preferably a cylindrical outer container 1 having a concave bottom 2 provided with a removable drain plug 23 for the purpose of removing the accumulation of water and sediment when it is not desired to take the device apart for complete cleaning.
Serial No. 64,319..
It will be noted that when the interior portions are removed as well as the plug 23 the container 1 may be used as a funnel.
Located near the lower part of the outer container 1 and several inches above the bot tom 2 is positioned an outlet pipe 4 secured to the sides of the container 1 preferably by means of anged bearing members 5 and 6 which form a support for the inner filter member 3 hereinafter described. The pipe 4 projects inwardly through one side wall of the container andl has secured by means of a coupling 4a a flexible hose member 7 for the purpose of more conveniently direct ing the flow of gasoline orthe fluid to b iiltered into its receptacle. l
lVhen the hose member 7 is not in use, it may be secured in the position shown by means of spring 8 engaging the lower end of nozzle 7a. Y
The inner lhopper member 3 is preferably of frusto-conical `shape and terminates in a cylindrical wire lter screen member 11 se, curedV to its lower portion. This screen member 11 is composed of two spaced apart circular flanged plates 12 and 13 held in spaced relation by a plurality of tubes 14 through which the gasoline freely passes from the hopper 3 to the space between the inner walls of the container and the filter screen 15. The tubes 14, it will be noted are preferably flanged and soldered in place to provide astrong and durable construction.
The filter screen 15 is preferably made of very fine mesh bronze screen of a size approximating 200 thereby to eliminate the passage of water or sediment to the interior of the tank.
In thel center of the lower circular plate 13 is an aperture surrounded by a circular fiange wheel .1G provided with elongated slots 17 for permitting the free passage of gasoline from the interior of the screen 15 out through the central aperture in the plate 13. The fitting 18 associated with the protruding sleeve 19 cooperates with this aperture for directing the flow of gasoline into the outlet pipe 4. rlhe lower part 19 of this fitting is provided with a boss 20 for the support of a threaded rod 2l which passes through the upper plate 12 and is threaded at its upper end for the reception of a nut 2Q. This nut when screwed down securely holds the internal parts of the filter in operative relation and on removal the sus` filter' may be bodily removed from the container 1 for the purpose of cleaning or using the receptacle 1 as a funnel or container.
It is believed that the o eration of this device will be clear `from t e above.
It may be stated, however, that the unfiltered gasoline is poured into the hopper 3 and passes down throughthetubes 14 thus allowing the Water and sediment to collect in the concave bottom 2. The gasoline then passes in through the screen 15 and is thus thoroughly filtered and cleaned before pass ing out through the slot 17 to the outlet pipe 4 and nozzle 7a. At intervals the block 23 is removed for the purpose of removing Water and sediment. When a thorough over-hauling is desired, the nut 22 is removed permitting all of theparts above the outlet pipe 4 to be removed. z
It Will thus be seen that the present invention provides a simple and practical filter, reliable and efiicient in operation, inexv pensive to manufacture, durable in construe tion and Well adapt-ed to accomplish, among others, all of the objects and advantages herein set `forth.
vW'hat I claim is 1. In a portable strainer of the character described, in combination, an outer container',
a hopper, a member attached to the hopper, the side Wall thereof being a. filter and Well above the bottom of the container, means extending through the member longitudinally of the container for conducting an entering fiuid from the hopper to the bottom of the container, means for conducting the fluid to the exterior of the container after it has passed through the filtering Wall, and means connecting the conducting means with the filtering member.
2. In a portable strainer of the character described, in combination a container, a vertically disposed filter screen of drumlike construction having its central outlet communicating with the exterior of the container, and vertical conduits extending through the filter for conducting a fiuid therethrough prior to its being filtered by the vertical screen.
3. In combination, a cylindrical filter member having closed top and bottom and a filtering side wall, conduits extending` through said member for conveying an entering fluid through the member prior to its being filtered, a container in which said filter member is centrally disposed, and an outlet from the interior of said strainer to the exterior of the container, said container being provided at its lower part with a normally closed opening for permittingthe removal of sediment or Water as and whenV desired.
