DISPENSING-CAN.

Specification of Letters Patent.

Patented May 14., 1912.

To all whom; it may concern:

" rooted to the provision of a fluid containing can of such a construction that its contents may be ejected without tilting the can.

More specifically, our invention resides in the provision of an air compressing device directly applied to the can and efiective when operated to introduce air under pressure into the tank of the can and upon the surface of the fluid for forcing such fluid outwardly through a discharge'pipe carried by the can.

Our invention further consists in the provision of a structure whereby the compressed air within the can may be directly admitted to the pipe at a point nearer its upper end, thereby counteracting the normal effect of the air upon the body of the liquid within the tank. We preferably accomplish this by the provision of a valve in the discharge pipe at a point just within the tank, the opening of such valve serving to admit the air under pressure into the discharge pipe. In the embodiment of this conception, we desirably provide a valve structure which is automatic in its nature. By this, we mean that the movement of the swinging discharge pipe to an operative position or rather to a position best suited for delivery of the fluid is utilized to close the valve structure and thereby exclude direct admission of the air to the pipe. From this it will be understood that the swinging discharge pipe is normally in inoperative position with its discharge orifice above the top of the tank and with the valve structure opened to admit the air under pressure directly to the discharge pipe to out off the flow of fluid theret-hrough. We further provide an indicator forautomatically disclosing the level of the fluid within the tank, which indicator is peculiarly constructed to comprise a reciprocating indicator element movable through the jacket of the tank which discloses any different volume of fluid within the tank by a greatly reduced travel.

Our invention further comprises various novel features of structure which will be hereinafter pointed out in the specification and defined by the appended claims.

The preferred embodiment of our invention is shown in the accompanying drawings in which similar characters of reference designate corresponding parts and in which,

Figure 1 is a top plan view of our dispensing can in assembled condition and showing the discharge pipe in its preferred position of operation, Fig. 2 is a side elevation of our dispensing can, Fig. 3 is a vertical section of our assembled dispensing can, Fig. 4 is a view taken on line H'of Fig. 3, looking in the direction of the arrows and showing the structure of the float and connection for controlling the indicator, Fig. 5 is a vertical section of a valve structure mounted upon the tank of the can for releasing the air under pressure therefrom said valve structure being incorporated into the cap for the filling opening of the can, and Fig. 6 is a section taken on line 66 of Fig. 3 and showing the valve structure carried by the dischargepipe.

In the drawings, our dispensing can is shown as comprising a tank 1 having a carrying bail 2 of ordinary form and having its bottom provided with a depression 3 with an upwardly extending pin 4. The discharge pipe shown comprising a vertical interior portion 5 resting in the depression 3 and embracing the pin 4; It will be seen that this lower extremity of the pipe 5 which embraces the pin 4: is cut away as at 6. The upper end of the discharge pipe portion 5 is preferably shouldered or provided wit-h a shouldered sleeve 7 rigidly secured thereto, the said pipe and sleeve being apertured as at 8. Embracing the said sleeve and resting upon the shoulder 7 thereof is a collar 9 apertured as at 10 and extending through the upper wall of the tank. This sleeve 9 is stationary and the portion 5 of the pipe together with the shouldered sleeve rotate therein being rigidly secured to and feeding the discharge nozzle 11. With reference to Fig. 3, it will be seen that the discharge nozzle 11 is in operative position and that the-apertures or ports 8 and 10 are out of alinement. Movement of the discharge nozzle 11 into normal position causes the ports 8 and 10 to aline and effect communication between the interior of the tank and the pipe.

The indicator structure of our invention desirably comprises a float 12 carried upon a concentric sleeve 13 depending below the float 12 and having cut away port-ions 13 to aline with the cut away portions 6 of the discharge pipe when the float is in lowermost position. The float 12 is desirably embraced by a yoke 14 extending across the upper surface thereof and embracing the sleeve 13 and downwardly bent at its extremity to form perforated ears 15. There is provided a bail 16 having a T element for the support therefrom of a rod 17 loosely connected to and capable of a telescoping action upon or within a lever element 18 carried at its opposite extremity by a pivot bearing 19 secured to the interior wall of the tank. The indicator proper comprises a rod 20 pivot-ally secured upon the element 18 and extending vertically upward through the upper wall of the tank and into a transparent casing or some similar" air tight casing 21, which casing may be suitably graduated. If desired 1 may provide an antisplash member 22 in the form of a disk of metal stamped to concave form and centrally apertured for the passage therethrough of the indicator 20. It will be observed from the above description of our indicator structure that we have provided an indicator proper which is automatically movable into view from within the tank upon the rise or fall of the fluid contained therein, but that the length of the indicator disclosed is definitely and comparatively reduced owing to the transverse telescoping lever comprised of the members 17 and 18.

The air compressing device desirably utilized in our dispensing can is best shown in Fig. 3 and comprises a main cup 23 having a central aperture 2 1 and concentric spaced annular grooves 25 and 25 coactively forming an intermediate seat for an anti-splash cup 26 substantially identical in form with the cup 22. The edge of this anti-splash cup 26 fits within the space between the annular grooves, and the outer main annular groove fits closely within the opening in the top of the can. Thus, it will be seen that there is provided a simple and air tight construction. Vithin the cup 26 and carried by the cup 23 is a one-way valve structure 27 comprising a stamped disk 28. Cooperating with the cup 23 is a diaphragm 29 of flexible material and having its outer peripheral edge clamped upon the edge of the cup 23 by a crimping ring 30. This diaphragm is desirably clamped at its central area between plates 31 and 32 having relatively diverging peripheral edges and perforated for the passage of air therethrough and into a one-way valve cup 33, likewise comprising a stamped disk valve 34. The plates 31 and 32 are desirably clamped together and maintained in position by a bridge member 35 of stamped material and having a lug 36 extending through a hood 37 and pierced for the reception of an operating lever 38, shown in Fig. 1, as being pivoted to a member 39. The filling orifice for the tank of our dispensing can is desirably closed by a cap 40 having its upper wall apertured as at 4.1, which aperture is closed by a valve 42 carrying a valve stem 43 and a button 14. This valve 42 is normally maintained in position by a coil spring 415. i

In operation it will be understood that, considering it is desired to discharge oil from the can, the nozzle 11 is moved to operative position and the lever 38 is operated to operate the diaphragm. This serves to force air into the tank of the can under pressure which necessarily causes the discharge of the fluid through the discharge pipe. If it is desired to immediately shut off this discharge, the button 14 upon the cap 10 may be depressed to permit the compressed air to escape from the tank; or the nozzle 11 may be swung to normal position, which will cause the ports 8 and 10 to aline, thus permitting an influx of the air under pressure into the discharge pipe. Thus it will be seen that there are provided two means for instantaneously cutting off the discharge of fluid from the can. Further it will be seen that the float is raised or lowered in accordance with the volume of fluid in the tank and that such raising or lowering of the float produces a Visual indication of the quantity of fluid in the tank. It will be further noted that the indication is effected by a reciprocable indicating rod having a movement comparatively small with relation to the movement of the float. It will further be seen that the air compressing device is constituted of parts readily made and is further provided with a rigid crimping ring for its peripheral edges together with clamping plates for the central area thereof which are calculated to avoid fraying of the diaphragm. In addition, it may be noted that applicants structure of bottom and lower extremity of the discharge pipe together with the particular form of the sleeve 13 all serve to permit a removal of practically all the contents of the tank. In more thorough explanation of this, it will be apparent that the depression of peculiar form in the bottom of the can and in which rests the lower end of the discharge pipe is of such a nature that practically all of the fluid in the can gravitates into such depression. Thus, when the can is almost empty the fluid therein concentrates in this depression and the discharge therefrom is facilitated by the cutaway portions in the lower end of the discharge pipe as well as by the cutaway portions in the lower end of the journal sleeve, upon which the float is mounted. Actual experiment demonstrates that such a structure renders possible the discharge of substantially every drop of fluid in the can.
