CLOSURE.

Application filed February This invention relates to closures for the intakes of storage or other receptacles such for example as gasoline tanks, oil reservoirs or radiator tanks of automobiles.

The objects of my invention are to enable quick and ready access to the receptacle openings for lilling, and to secure this advantage in a closure which is easy to operate, capable of normally maintaining a good fluid tight seal in preventing evaporation of the receptacle contents; and which, on the whole, iscapable of very economic manufacture from'sheet metal die stampings.

In the drawings Fig. I is a perspective view of closure conveniently embodying my invention.

Fig. II is a similar view showing the control rotor turned to open position for filling of the receptacle.

Fig. III is a longitudinal sectional View of the device.

Fig.- IV is a cross section taken as inclicated by the arrows IVIV in Fig. III; and

tive views of theparts which collectively constitute the device.

As herein shown, the closure comprises a casing 10 and a rotor 11 which is accommodated in the horizontal cylindric portion 12 of the casing to control communication between aligned diametrical upper and lower ports 13, 1% therethrough. At the bottom, the casing 10 has an annular base flange portion 15 which is internally threaded for application to the inlet neck of the receptacle whereof a portion is shown at N in Figs. III and IV, and may be equipped with one or more set screws 16 for security of the device against subsequent displacement and illicit removal. The body portion 17 of the rotor 11. is semi-cylindric in configuration, its circumferential dimen. ion approximating a half circle in extent as will be best seen from Fig. VIII, and it has an opening '18 adapted for registry with the upper port 13 of the casing 10 as well as a cut outat 19 to clear the lower port ll when said rotor is in open position. The extent of movement of the rotor 11 is limited by engagement of offset projecting grasp lugs 2021 of its circular end 22 (Figs. I, II and VII) respectively with stops 2324 on the casing 10. lVhen the rotor'll is in closed position, a segmental arcuate plate 25 forming a part Figs. V, VI, VII and VIII. are perspec- 5, 1926. Serial No. 86,133.

thereof and which is rounded in conformity with the exterior curvature of the cylindric rotorcasing 12, serves as a cover over the upper port 13. I

In operation of the device, turning of the rotor 11 clockwise from the position of Fig. I with the aid of the grasp lugs 20, 21 and as far as permitted by the stop 24;, will re-' suit in the shifting of the segmental cover plate 25 from over the upper port 13 of the casing 10 and simultaneous registry of the rotor opening 18 with said port as shown in Fig. II. At the same time. the cutout 19, of the rotor 11 is of course broughtinto coincidence with the lower port 14 of the easing 10 so that communication is had through the device for filling or inspection of the receptacle with which it is used. Turning of the rotor 11 counterclockwise from the position of Fig. II will obviously result in restoration of the device to closed position with the imperforate portion of the rotor body 17 closing the lower port 14 of the casing 10, and the segmental cover plate 25 overlying the upper port 13 as in Fig. IV.

The operation of the device being now well understood, I will next proceed to describe the manner in which it can be conveniently and inexpensively constructed of sheet metal. die stampings. "Ihe casing 10 is preferably made in two sections which are separately shown in V and VI, and respectively designated 10, 10 The section 1O is cup shaped for service as the rotor chamber and has a. lateral neck 26 in prolongation of the port l l adapted for force fitment axially into the section 10 which affords the annular base flange 15 by which the. device is secured. The rotor limiting stop 23 is shown as an integral edge project on of the section 10*, and the limiting stop 24 as a. slight circumferential protuberai'lce of thesection 10". After assembling, the

two component parts of the casing are per-' manently soldered or welded together at the junction of the neck 26 of part l0 inter LEI dius of curvature slightly larger than that of the rotor chamber of the casing 10 for capacity to engage the chamber wall With snug fluid-tight fitand to hold the rotor 11 frictionally in shifted positions. The inwardly directed radial tongue 27 at one end oi part 11, enables attachment of the latter coaxially to the discous portion of part 11 soldering or welding being here again preferably resorted to for the purpose of permanent connection. The tongue 28, at the opposite end of the part 11 is pierced as at 29 in line with the rotor axis for pivotal engagement with a shouldered stud 30 projecting centrally inward from the back wall of the rotor chamber section 10 of the easing 10; and a convenient means is employed in conjunction with the stud, such for example as a nut 31., to bear against the tongue 28 and retain the rotor ii in place in the casing 10, said tongue 28 being amply springy to hold the discous portion of part ll firmly in frictional contact with the contiguous circumferential edge about the open end of the rotor chamber. If desired, the nut 31 may be permanently secured to the stud 30 by soldering or welding ai'ter placement of the rotor 11 in the casing 10. From Fig. VII it will be noted that the segmental cover plate 25 and the grasp lugs 20, Q1 of the rotor ll are formed as integral parts of the member 11 Having thus described my invention, I claim:

1. A receptacle closure comprising a cylindirc rotor casing having opposed ports and a semi-cylindric rotor for controlling communication through the casing, said rotor having its major body portion jl ree relative to the ends to aliiord inherent capacity for circumferential flexure to engage the wall of the casing with fluid tightness.

2. A receptacle closure comprising a tubular rotor casing having opposed ports, a rotor for controlling communication through the casing, an end member attached to the rotor having an arcuate cover pl ate. and said rotor being of semi-cylindric configuration with the major portion of its body wall. inherently springy to aiiord ca 'iacity tor circinn'terent al exp nsion in engaging the wall of the casing with tiuid tightness.

3. A receptacle closure comprising a tubular rotor co ring having diametrically opposed ports, a tubular rotor having an opening and a cut-out portion adapted to open and close communication through the casing, an end member attached to the rotor including an integral arcuate cover plate, and said rotor being of semi-cylindric configuration with the major portion of its body wall free relative to the ends thereof for expansive engagement with the casing wall to insure fluid tightness.

A receptacle closure comprising a hollow tubular rotor casing with aligned diametrical ports, and a rotor to control communieation through the casing, said rotor having segmental portions to cover one of the ports interiorly "of the casing and the other eXteriorly of the casing.

6. A receptacle closure comprising a hollow tubular rotor-casing with aligned upper and lower diametrical ports, in combination with a rotor constructed entirely of die stamped sheet metal embodying a semi-cylindric body portion fitting. into the casing to govern the lower port aforesaid and an attached discous end member with an integral lateral segmental plate projection a.daptcd to serve as a cover for the upper casing port.

l. A I'QCGPlHClO closure comprising a 'llOl. low tubular rotor casing with aligned upper and lower dian'ietrical ports, in combination with a rotor constructed entirely of d e stamped sheet metal emliodying asemi-cylindric body portion and an attached discous end member. said body portion fitting into the casing to govern the lower port ot the latter and having at opposite ends integral iniwirdly extending radial arms, one adapted tor pivotal connection axially ot the casing for retainment of the rotor and the other for permanent connection to the end member aforementioned, and said end member having a segmental lateral plate projection adapted to function as a cover "for the uppercasing port and integral grasp projections to cooperate with stops on the casing in limiting rotor movement;

In testimony wlereol', 1 have hereunto signed my name at Philadelphia, Pennsylvania, this 30th day of January, 1926.
