GUGLIELMO GIOVANNONI, OI TURINI, ITALY, ASSIGNOR T0 bTTORINO POMILIO, OF NEW YORK, N. Y.

rrmna roa GASOLINE.

Specification of Letters Patent.

Patented Jan. 3, 1922.

To all whom it may concern:

Be it known that I, GUoLmLMo GIovAN NONI, subject of the King of Italy, and resident of Turin, Italy, have invented certain new and useful Improvements in Filters-for Gasoline, of which the following is-a specification.

This invention relates to the filters intended to be inserted into pipings leading liquids to or from tanks or the like and particularly to filters intended to be used in connection with gasoline tanks or carbureters for explosion engines.

This invention has for its object a filter in which the filtering surface has a large area and is formed by a plurality of sections arranged in such a manner as to insure the proper operation of the device and the flow of the liquid also when a portion of the filtering surface should be obstructed, and to reduce the liability to said obstructions.

The annexed drawing shows by way of example a construction of the device according to the invention, and Figure 1 is the side view and Figure 2 the central section of the same. Figure 3 is a section on line 3-3 of Figure 2 looking in the direction of the arrows.

As shown in said figures, the filter comprises a receiver 1 to which the liquid is supplied through an upper port 2 intended to be connected with the feeding pipe not shown; the upper wall of said receiver is provided with a central sleeve 4 projecting downwardly into said receiver and communicating with the upper exhaust port 3. At the lower end of said sleeve 4 is secured a deflecting bell or sleeve 5 extending to near the bottom of said receiver 1, this bottom being formed by a cup 1' suitably connected with said receiver 1.

Inside said hell 5 are arranged the filtering means which, in the construction illustrated, are formed by three concentric drums 6, 6and 6" made of wire gauze. The outer drum 6 is secured at its lower edge to a v disc 7 and has its upper edge secured to the outer edge of a plate 8 to which is also secured the upper edge of the intermediate drum 6. This latter in turn has its loger o a having flange or disc 9 the inner drum 6' its lower edge secured to the same flange 9 whilst its upper edge is connected with the mouth of sleeve 4.

As shown in the drawing, the disc 7 is imperforate, with the exception of a central hole for mountin purpose as hereinafter described, whilst p ate 8 is made in the form of an annular ring to leave a passage or passages between drums 6 and 6" and finally the disc 9 is likewise provided with holes 9 inits portion located inside the inner drum 6", forming a spider as shown in Figure 3.

The mounting of said filtering means is made by means of a central spindle 10 which passes through the central holes of discs 7 and 9 and has its threaded end screwed into a socket 12 secured to the lower cup 1, said disc 7 being adapted to rest against the upper surface .of the socket 12; the spindle 10 is provided with a shoulder 16, a spring 15 being arranged between said shoulder and disc 9 to hold the inner drum 6 extended and straight. Finally the spindle 10 is provided at its upper end with a manipulating knob 11.

The central socket 12 secured to the cup of bottom 1' of the device is hollow and provided with holes 13, flush with the surface of said bottom, and with a cook 14 arranged at its lower end, this cock being intended to be operated to discharge from receiver 1 and cup 1 water'and impurities or foreign matters .which may accumulate in the same.

The liquid supplied through port 2 is deflected by bell 5 and is caused to flow downwardly along the outer surface of the same so as to enter into said bell and to rise along its inner surface owing to the imperforate transverse disc 7; thereafter the liquid is drums before reaching the exhaust passage and the flow of said liquid is not prevented should one or two of said drums be obstructed by impurities or foreign matters.

Further it is to be noted that the liability of said drums to be obstructed is reduced because the impurities or foreign matters which may be carried about by the liquid are unable to come into contact directly with said gauze drums as the liquid before reaching the same is caused to flow downwardly along the outer surface of the bell 5 and thereafter to rise along the internal surface of the same so that said impurities are caused to fall down on the bottom of the receiver and may be discharged therefrom by means of the holes 13 and cock 1 1.

Obviously the number of the gauze drums and the particular construction of the parts .may be modified according to the requirements without departing from the scope of this invention. a

What I claim as my invention and desire to secure by United States Letters Patent is:

1. A filter for gasoline comprising a receiver, a deflecting sleeve projecting into said receiver to near the bottom of the same, a feeding port opening into said receiver, a plurality of concentric gauze drums inside said. sleeve, transverse partitions connecting the adjacent edges of said drums, passages in said partitions to allow the gasoline to enter into the annular spaces between said drums and an exhaust port opening into saidsleeve in the space enclosed by the inner drum.

2. A filter for gasoline comprising a receiver, a deflecting sleeve projecting into said receiver to near the bottom of the same, a feeding port opening into said receiver, a plurality of concentric gauze drums, inside said sleeve, transverse partitions connecting the adjacent edges of a number of said drums, passages allowing the gasoline to enter into a number of the annular spaces enclosed between said drums, an exhaust port opening into said sleeve into the space enclosed by the inner drum and other passages allowing the gasoline thus entered into the said spaces enclosed by said drums and transverse partitions to flow into said exhaust port.

3. A filter for gasoline comprising a receiver, a deflecting sleeve projecting into said receiver to near the bottom of the same, a feeding port opening, into said receiver, three concentric gauze'drums inside said sleeve, a transvers partition closing the lower mouth of the outer drum, a transverse partition connecting the upper edges of the outer and intermediate drums and having passages between the intermediate and inner drums, a transverse partition connecting the lower edges of the intermediate and inner drum, this partition having passages to cause the hollow of th inner drum to communicate with the space'enclosed between the outer and intermediate drums and associate partitions, an exhaust portopening into said sleeve the upper dge of the inner drum being connected with the mouth of said exhaust port, and means for discharging the foreign matters accumulating on the bottom of said receiver.

4. A filter for gasoline comprising a receiver, a deflecting sleeve projecting into said receiver to near the bottom of the same, a feeding port opening in said receiver, a plurality of gauze drums inside said sleeve, said drums having transverse walls provided with central holes, a central spindle passing through said drums and holes to hold the same in place.

5. A filter for gasoline comprising, a receiver, a deflecting sleeve projecting into said receiver to near the bottom of the same, a feeding port opening into said receiver, a plurality of gauze drums inside said sleeve, a central spindle passing through said drums to hold the same in place, a hollow socket projecting from the bottom of the receiver against which said drums rest,

said spindle being screwed into said socket, holes in the wall of said socket near the surface of said bottom and a cock adapted to cause said socket and receiver to communicate with outside.

6. A filter for gasoline comprising a receiver, a deflecting sleeve projecting into said receiver to near the bottom of the same, a feeding port opening into said receiver, a plurality of gauze drums inside said sleeve said drums having transverse walls provided with central holes, a central spindle passing through said drums and central holes to hold the drums in place, a shoulder on said spindle and a spring between said shoulder and the transverse wall of the inner drum to hold the same extended and straight.
