2 Claims.
This invention relates to gasoline lters and particularly to a type of lter to be used in connection with the delivery or service pump of a service station, to be interposed between the outlet of the pump or gravity feed tank and the exible delivery hose.
One of the objects of my invention is to provide a lilter of this character which while being kept in a compact form will have a large riltering capacity so as not to materially restrict the speed oi iiow of gas from the tank or pump into the hose.
Another object is to construct and maintain the filter element of the device so that it may be very easily removed for cleaning and very easily cleaned when removed,
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.
These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.
In the drawing similar characters of reference indicate corresponding parts in the several views:
Figure 1 is a top plan view of my improved lter.
Figure 2 is a sectional elevation of the same on the line 2 2 of Figure l.
Figure 3 is a transverse section on the line 3-3 of Figure l.
Referring now more particularly to the characters of reference on the drawing, the iilter comprises a rectangular head I having an initially horizontal inlet passage 2 on one side centrally of its ends and an opposed outlet passage 3 on the opposite side; said passages being arranged for connection to the tank or pump outlet conduit and the hose respectively.
A glass bowl 4 depends from the head and is removably sealed and clamped against the under face of the same by suitable means. In the present instance such means is shown as comprising spaced U-shaped straps 5 extending transversely about the bowl at spaced points in its length. 'Ihese straps may be provided on their upper ends with stud extensions 6 which project through lugs 'I on the head, there being nuts 8 on the studs above the lugs. The bowl may be considered as being trough shaped, being transversely semi-circular at the bottom with vertical ends, and its rim being symmetrical to and substantially the same size as the head.
1935, Serial No. 28,859
(Cl. B10-165) The inlet passage 2 is branched inside the head, the branches 9 extending lengthwise of the head and discharging into the bowl centrally of its width and toward its ends. The outlet passage 3 leads to a termination at the 5 bottom face of the head at the center of the same, where it is connected to the lter.
The nlter comprises a wire framework consisting of circular ring-like end members l0 disposed in vertical planes, connected by longi- 10 tudinally extending wires Il at and above the center of the ring circles. Theframework is covered by the shammy i2 in such a way that an enclosed chamber I3 of semi-circular form in cross section is provided between the top cover- 15 ing of the shammy which extends over the wires H between the end members, and the bottom covering which extends directly across between the lowermost wires Il; the end frames I0 being also of course covered with and enclosed by 20 the shammy.
The filter element at the top is provided with an upstanding rigid neck or outlet tube M. This nts into or against the lower end of the passage 3 and is removably secured to the head by suit- 25 able means, such as a flange on the neck engaging the head there being cap screws I6 therethrough screwed into the head. The filter is disposed symmetrical in the bowl and the end walls of the lter, formed by the ring-like end 30 frames Il) and the shammy coverings thereon, are disposed concentric with but of course are smaller than the bottom portion of the bowl, so as not to restrict the flow of gas between said end walls and the walls of the bowl.
In operation it will be seen that gas will be fed into the bowl adjacent both ends from the branched inlet passage and such gas can only pass into the outlet passage either through the top, bottom or end walls of the shammy covering 40 of the lter frame. 'I'he area of the shammy exposed to the gas is so great compared with the size of the inlet or outlet passages that the lter has as great a capacity as the outlet, so that no restriction to the full steady iiow of gas 45 from the filter is had.
The end frames of the lter extending some distance below the bottom of the filter chamber and toward the bottom of the bowl, act as baffles or deflectors tending to catch and prevent any foreign matter deposited in the bowl with the incoming gas from being drawn up against the main bottom covering of the filter chamber to possibly choke or at least restrict the filter action of the same.
When it is necessary to remove the filter for cleaning or replacement of the covering, it is only necessary to remove the bowl and withdraw the screws I5. The entire filter area of the shammy being then freely exposed and lacking any small pockets or crevices may be easily and thoroughly cleaned.
From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.
While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
Having thus described my invention, what claim as new and useful and desire to secure by Letters Patent is:
1. A gasoline filter comprising an oblong head, inlet and outlet passages leading to the under surface of the head from opposite sides o the same, the inlet passage being branched within the head, the branches leading to terminations in the under face of the head adjacent thc ends thereof, an oblong bowl depending from and secured to the head, a lter extending lengthwise in the bowl and shorter than the distance between the terminations of said inlet branches, said lter including an enclosed chamber cornmunicating with the outlet passage and the Walls of which are of filter material, the bottom of the chamber being some distance above the bottom of the bowl, but the end walls of the lter depending below the said bottom of the chamber to near the bottom of the bowl.
2. A lter comprising an oblong bowl, a lter extending lengthwise in and spaced from the walls of the bowl, means to feed liquid into the top of the bowl in the spaces between the ends thereof and the ends of the filter, said lter including an enclosed chamber having a top outlet and the walls of which are of filter material, the bottom of the chamber being some distance above the bottom of the bowl; and extensions on and depending from the end walls of the chamber to adjacent the bottom of the bowl.
