N. A. ARvlNs ET AL FILLING AND STRAINER DEVICE Filed Feb. 2e, 1942* INVENTORS 2@ Y NATHAN A. HRV/N5 ATTORNEY/ Patented Mar. 21, 1944 Meer `UNITED STATES PATENT ori-*ICE FILLING AND STRAINER DEVICE Nathan A. Arvins and Abraham A. Arvintz, Brooklyn, N. Y., assignors to Seal-O-Strain Corporation, a kcorporation of New York Application February 26, 1942, Serial No. 432,464 s claims. (C1. 21o-166) This invention relates to what are commonly referred to as iilling devices used in conjunction with tanks or containers of various types and kinds in the transmission of fluids from one tank or container to another, such, for example, in the transmission of fuel, fuel oil and other uids of this type and kind, particularly where the straining of the fluid transmitted is desirable. More particularly the invention relates to filler and strainer devices employing single inlet and outlet passages, each havin-g a 'dual valve, and said dual valves controlling independent passages through the device whereby a substantially constant transmission of fluid may be performed, while at the same time intermittently cleaning strainer devices in the separate passages; of the device to maintain uninterrupted or retarded transmission of strained fluid. The novel features of the invention will be best und'erstood from the following description when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed and in which the separate parts are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a longitudinal sectional view through' a device made according to my invention, the section being substantially on the broken line I-I of Fig. 2.

Fig. 2 is a transverse sectional vievv on the line 2-2 of Fig. l, and

Fig. 3 is an end and sectional view substantially on the broken line 3-3 of Fig. 1.

In the use of what is commonly referred to as lling devices or caps, and particularly devices of this kind using strainer devices to strain fluid transmitted therethrough, it hasbeen the common practice to shut off the transmission of fluid intermittently to clean' the strainer employed or to substitute a new strainer, and this often times f one common end of each passage opening into a single intake controlled by two valves, and the other end opening into a common discharge end controlled by two valves. Means is also provided Vwhereby the valves controlling the separate passages may be retained-in closed position so that either valve may be operated, and`further in the provision of means for quickly removing the strainer from the other unused chamber thereb facilitating a constant transmission of fluid through the device from the receivingend of the discharge end thereof. It is also a ieatureof our vinvention to provide means securely retain,- ing the valve, release in inoperative positionvand against unauthorized manipulation. thereby ef,- fecting a positive seal and closure for the supply or storage tank controlled by said device.

In the accompanying drawing one adaptation of the invention is disclosed, and in the several figures, Il) represents the casing of thedevices Which-is more orless oblong in form and is divided by a central longitudinal partition II into two transmission chambers orpassages I2, I2d, which are also divided intermediate the closed end Wall I3, and the wall having thevlarge openings iii therein, by a transverse partition wall I5. VThe partition I5 divides the casing. into an admission end portion I6, and discharge end portion I'l opening into the separate chambers I2,L IZd. At the admission end areintakeports I8, I-Sa, in which are supported valve seat rings I9, having webs or arms 20, supporting a bearing collar 2I, for the stems 22 of valves 23. The valves 23 are normally held seated upon the rings I9,by springs 24 seating on the bearings 2| and on discs 2E secured to the stems 22. The stems 22 are also guided and supported Vin bosses 26 formed in an inlet housing 21, detachable with respect to the inlet end I6 vof the casing. The housing 2l has a coupling ilange 28 around the inlet port 2S of the housing for attaching the housing to any suitable support which might be a pipe, or' infact, this flange may be directly coupled to a tank.' .As both valve units are of the same construction, the brief description of one applies tothe other and this will also apply to the dual valves controlling the exhaust port 30 formed in the exhaust housing 3| which is coupled with the exhaust end I'I of the casing. Y l,

The housing 3| is substantially the same asthje housing 2'I insofar as opening intothe chambers or passages I2, I2a is concerned. The casing "I has two ysimilar exhaust ports 3 2 in which are arranged lvalve ring yseats 33 upon which 'exhaust valves 34 are seated. The stems 35 of the valves operate in bearings 136' carried by arms or websl integral with the rings 33. Springs 38 are arranged on the stem 3.5v to normally support the valves 34 in seated position. 'The housing 3i is also flanged centrally as seen at 39 for attachment to any suitable support, or this flange may serve as means for coupling transmission tubes or pipes with the tank or container to be filled.

Arranged in the discharge end I1 of each chamber or passage I2, I 2a is a long thimble shaped strainer 40, the opening end of which carries a ring 4I, seating in the partition I5. A plurality of webs or spokes 42 extending radially from the ring 4l supports a central hub 43, with which is slidably coupled a rod 44. The outer end of the rod is secured to a cover 45 which is firmly secured in position and readily detached by a clamp arm 46 pivoted at one end to the casing as seen at 41, and detachably coupled with a pin 48 on its other end. The central portion of the arm 46 supports a screw 4,9, having a large operating handle 50, and the screw is adapted to apply pressure to the closure plate 45, as clearly seen in Fig. 1, in retaining the plate in position. As each closure plate and securing means is of `identical construction, again the brief description of one applies to both and this is also true of the strainer and other parts.

In order to compensate for proper seating of both the strainer and the closure plate, the strainer is capable of sliding movement on the inner end of the rod and is held by the spring 5I in secure seated position. A collar 52 on the inner end of the rod serves as a means engaging the strainer to withdraw the same through the opening I 4 when the closure plate or cap 45 is removed.

The housing 21 is provided at one side thereof and in alignment with the stems 22 of the valves 23 with bosses 53. In these bosses are rotatably supported lock rods 54 having offset crank-like lock arms 55 at their inner ends adapted to engage the discs 25 to normally retain the valves 23 in seated position and against accidental opening. The rods 54 pass outwardly through stuifing boxes 56 and have at their outer ends, heads 51, by means of which the rods may be rotated to move the lock arms 55 into operative and inoperative position-s. The heads 51 carry offset latch arms 58 cooperating with latch lugs 59 on the housing 21 to jointly receive a pad lock or other key controlled device 60 to positively retain the lock arm 55 in operative position. At this time it would be well to say that the primary purpose of the lock SI1 is to prevent tampering with any type of storage supply of fluid in the period of transportation or storage to prevent unauthorized removal of the fluid through the device. The head 51 of the rod 54 also has a finger 6I which may be used to limit inward sliding movement of the rod and further as a gauge means controlling opening movement of the valve 23 whenever it may be desirable to limit this opening movement of the valve.

In the use of the filling and strainer device the fluid to be transmitted therethrough from the inlet housing 21 to the outlet housing 3| is-rst passed through one of the chambers, for example, the chamber I2, and this is accomplished by releasing the lock 55 from the inlet valve 23 which opens into the chamber I2. Thus, as fluid is forced under pressure into the housing 21, the same will automatically open the valves 23 against the action of the spring 24 and admit the duid into the chamber I2, from which it will pass through the strainer 40 into the exhaust end I1 of the chamber I2 and out through the valve 34, registering with said chamber, the valve 34 being unseated by the pressure of the fluid as will be apparent. At this time it is well to mention that both the

valves

34 and 23 are automatically seated against any back pressures. In the transmission of a large quantity of fluid it may be possible that during the period of transmission the strainer 40, in the chamber I2, becomes clogged. Then the lock 55 controlling the valve 23 opening into the chamber I2a will be moved into inoperative position, the fluid will then be diverted to the chamber I2a, and then the valve 23 opening into the chamber I2 will be again seated by the lock arm 55. When so seated, the strainer 40 in the chamber I2 may be removed, as Vpreviously described, and cleaned and then replaced. In due time, should the strainer 40 of the chamber I2a become clogged, then the above operation is repeated by closing the valve 23 leading to the chamber I2a after the first mentioned valve has been opened to the cham.- ber I2. Where iiuids transmitted require an excessive amount of straining, the above operations may be repeated a number of times in the Vtransmission of one bulk or volume of fluid from a large tank or storage. It will bel apparent that even though clogging of the strainers may take place, quite often the quick attachment and detachment of the strainers which is provided will satisfy any requirement to which the invention would be applicable.

In the operation of shifting the transmission of uid from one passage to the other, no time factor is lost, in that the operation of the lock arm 55 controlling the valves may be conducted simultaneously in shifting one valve to an open position and the opposed valve to a closed position.

In the accompanying drawing the particular fastener means employed for securing the housings in position are omitted as in fact they form no particular p'art of the invention. It will be understood, however, that this housing will be secured to the casing I0 in the usual or any desired manner.
