I-IELGE HENRIC EMANUEL W'ERNEMAN, OF STOCKHOLM, SWEDEN CAN.

A plication filed September 2-, 1925, Serial No. 54,060, and in Sweden September 5, 1924.

In using oil cans of the type tapering upwardly, the oil is poured out by turning the can with its neck obliquely downwards to ward the opening or the place where the oil is to be poured in. Even if the greatest are is used in manipulating the oil can it often happens, particularly if the can is full, that the oil flows out too freely and is spilled before the neck of the can has been brought into the proper position adjacent the filling opening or inside the same. 7

The present invention has for its object to obviate such spilling, and for this reason the can is provided with a special valve device serving to keep the outlet closed while the neck is placed adjacent the filling opening or introduced into the same, so'that there is no risk of a portion of the oil being spilled. After the can has thus been placed into position, the valve device is opened by a simple manipulation, oil then flowing out without being spilled, after which the valve device is again closed, while the can still remains in its discharge position, so that no oil will flow out when the can is removed from the filling opening.

The cut-oh" means forming the object of the present invention consists, principally, in the preferred form, in two or more disks or the like arranged rotatably in relation to one another within the neck of the can, said disks afiording a tight fit with each other and being provided with openings disposed in such a manner as to register wholly or partly in a certain angular position of the disks, which latter then permit the oil to pass, while in another position the said openings are situated laterally of each other, the outlet being then closed.

The device is preferably made with two disks, one of which is attached in the neck of the can, while the other is rotatably arranged. The turning of the rotary disk is cifected'by means of a simple arrangement, which will he described more fully hereinbelow.

An embodiment of the invention is illustrated in the accompanying drawing. Fig. 1 shows a vertical section of a can embodying the invention. Fig. 2 is a top plan View of the can, and Fig. 3 shows the bottom thereof. Fig. 4 shows the details of the valve device drawn to a larger scale. I

The cylindrical can 1 is provided with a plane bottom 2 and a conical neck 4, from which projects the neck extension 8 Which shown in the drawing.

is preferably provided with threads adapted to receive a threaded cover to be screwed onto the neck extension, which cover is not Attached to the upper end of the conical neck i, either by soldering or in some other way, is a disk 3, the edge of which is turned down to form a flange which is connect-ed to the outside of the conical neck, sothat the disk will be retained in a position at right angles to the longitudinal axis of the can. Concentric with the said longitudinal axis is a pipe 5 extending between the disk 3 and the bottom 2 of the can, said pipe 5 being tightly connected with the bottom as well as with the disk. Extending through the pipe is a rotary spindle 6, the upper end of which is attached to a disk 7 bearing tightly against the disk 3. The disks 3 and 7 are each provided with two diametrically opposed openings 9 and 10 respectively, said openings being of the relative size and form illustrated in Fig. 2. The lower end of the spindle 6 extends below the bottom of the can, and is provided on its projecting part with a handle 11 serving as a means for turning the spindle. Inserted between the handle and the bottom of the can is a spring 12 serving to keep the disks 3 and 7 in tight contact with each other. The handle ll is preferably provided with a pointer 13 or other indicator adapted to indicate whether the disks 3 and 7 are in a closedor open position. 'By reason of the fact that the ends of the pipe 5 are tightly fitted againstthe disk 3 and the bottom 2, it is obvious that no oil can leak out from the can at these places. Leakage between the disks, whether from the inside of the'can or from the space outside the disks, is prevented, partly by the fact that the spindle 6, affords a tight tit with the pipe, and partly by the fact that the central portions of the'disks adjacent the spindle have so great a radial extension at every angle that large'tightening surfaces are obtained about the'spindle. the tightness of bearing of the said surfaces against each other being obtained by the spring 12.

The arrangement is used and acts as fol lows:

With the disks 3 and 4 in the closed position, the can is brought into a position with the neck extension 8 thereof adjacent or down into the filling opening or the place where the oil is to, be poured. The handle 11 is then turned by hand, so that the openings of the disks 3 and 7 are caused to regis ter, the oil then flowing out of the can without being spilled. After the desired quantity has thus been poured out, the handle is turned into closed position, whereupon the can may be removed from the filling opening, without any risk of spilling being incurred.

My invention atlords the further advantage that when the can is kept standing in readiness with the disks 3 and 7 in closed position, no accidental spilling of oil can take place even it the can happens to be upset.

Obviously, the construction of thefdevice may in many ways (litter from the structure discharge opening in the top, and a hollow leakage preventing member surrounding said spindle and tightly fastened to the top and bottom.

2. A- can comprising a main body portion formed circularly about a longitudinal axis, said body portion including a conical neck, a bottom, two contacting valve disks, one of said disks constituting a fixed top for the can and having its edge flanged downwardly to bear on the outside ofthe conical neck and arranged perpendicularly to said longitudinal axis, and the other of said disks being capable of angular movement with respect to the fixed disk, a spindle attached to the movable disk and extendingthrough the can and accessible on the outer side of the bottom, and a leakage preventing pipe surrounding the spi'ndle'and tightly fastened to the top and bottom of the can.

3. A can comprising a main body portion, a top, a bottom, said top having a discharge opening therein, a rotatable spindle extending through the can, a disk adjacent said top and in contact therewith and attached to one end of said spindle and having a dis charge opening in the same adapted, upon rotation of said spindle, to register with the discharge opening in the top, the other end of said spindle being accessible on the outside of the bottom of the can, a handle attached to the latter end of said spindle, a spring inserted between said handle and the bottom of the can in order to keep the disk bearing tightly against the top, and a hollow leakage preventing member surroundin said spindle and tightly fastened to the and bottom of the can.
