VALVE MECHANISM.

pplication filed. March 11, 1927. Serial No. 174.580.

'Ihis invention relates to improvements in valve mechanisms. i

The principal object of this invention 1s to provide simple means whereby the rotation of a single element will rotate a valve member for the purpose of cutting olf the discharge of a commodity therethrough.

Another object of this invention is to pro- `vide a device of this character which is simple in construction and therefore economical to manufacture.

Another object is to provide a device wherein a double seal will be effected.

A further object is to produce a device of this character which is equally applicable to either liquid dispensing or the dispensing of a dry commodity.

Other obj ects and advantages will be apparent during the course ofthe following de- V scription.

In the accompanying drawings forming a part of this specification, and in which like numerals designate like parts throughout the same,

Figure I is a fragmentary view of a collapsible tube having my invention applied there to,

Figure II is a top plan view of Figure I,

Figure III is a view similar to Figure I, partly broken away in order to show the mechanism thereof,

Figure IV is atopplan view of Figure I, with the cap removed,

Figure V is a bottom plan view of the cap, and

Figure VI is a view similar to Figure III showing the valve in shut-oil' position.

In the dispensing of commodities such as tooth paste and the like, it has been common to employ a screwed cap in order to retain the tooth paste within the tube. The result is that these screwed on caps are oftentimes lost, after which the tube cannot be closed and the result is that the commodity is unsanitary.

I have therefore provided a valve mechanism which may be inserted in the top of a tube of this character, which valve may be actuated by the simple rotation of the cap.

It is obvious that vmy device might be equally Well used in any position where it is desired to interrupt the How of a commodity from a source of supply as for instance in a water faucet, the principle being the same in both cases.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the upper end of a collapsible tube having a neck (i. This neck is partly cut away so as to form a ledge 7 upon which the trunnions 8 of my ball valve 9 rest. 'Ihese trunnions may be formed on the ball or secured thereto.

'I his ball valve has a passage 11 extending therethrough, which opening is adapted to register with a port 12 (see Figure III), The ball valve 9 rests in a seat 13 formed within the neck of the tube.

In order to rotate the ball valve 9 I employ a cap having an annular depending ringlike portion 111 which encircles the neck 6 and has its lower extremity crimped as shown at 16. This crimped portion engages an annular cap from being removed and at the same time permits the cap to rotate with respect to the neck of the tube.

A knurled rim is shown at 17 while a domeshaped portion 18 encircles the upper portion of the ball valve 9. rIhis dome-shaped portion has a discharge port 19 formed therein which is in axial alignment with the port 12.

A pin 21 extends through the knurled rim 17 and is adapted to enter a cam-shaped slot 22 formed in the surface of the ball valve 9.

The result of this construction is that when the cap is rotated in one direction, the pin 21 engaging the cam slot 22 will cause the ball valve to move to that position wherein the passage 11 will register with the ports 12 and 19, at which time the commodity may be dispensed. l

Rotation of the cap in the opposite direction will serve to move the ball valve so as to bring the passage 11 out of registry with the ports 12 and 19. thereby preventing furthr dispensing of the commodity' within the tu e.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes relative to the shape, size, material, and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subjoined claims.

Having thus described my invention, I claim 1. In a device of the character described, a receptacle having a neck portion, a hall valve positioned in saidv neck portion, a rotatable member encircling said neck portion, a cam recess 15 cut in the neck 6. This prevents the ,los

carried on said ball, and means associated with said rotatable member for engaging saidports formed in said rotatable member on said receptacle and adapted to coincide with a passage formed in said ball.

2. In a valve mechanism a receptacle having a discharge port, a ball valve positioned adjacent thereto, said ball valve having a passage therethrough, trunnions formed on said ball, a rotatable member mounted on said receptacle and adapted to rotate freely with re'- spect thereto, a cam formed in the surface of said ball, a pin carried in said rotatable member, said pin engaging said cam, an outlet port formed in said rotatable member, an inlet port formed in said ball, said inlet port and said outlet port being in axial alignment for the purpose specified.

In testimony whereof I afx my signature.

ELMER JOHNSON.
