WILSON, OF UPPER DARBY, PENN- SYLVANIA, ASSIGNORS TO THE HUFFMAN MANUFACTURING COMPANY, OF DAYTON,

OHIO, A CORPORATION OF OHIO LIQUID MEASURING AND DISPENSING CAN Application filed .Tune 13,

This invention relates to a liquid measuring and dispensing can, and has particular reference to a can which is provided with a port in the bottom of the same communicating with a flexible tube for draining the can while retaining the can in an upright position and a hand operated valve for controllin r the port.

n cans of the type just above described where there is provided means for retaining the port open, the delivery tube is sometimes returned to its upright position and the can refilled with the valve open. This results in filling the tube to the same level as the can is filled, thereby giving an excess amount of liquid, and when the tube is lowered to dispense the liquid, it is usually splashed over the outer surface of the article or thing into which the liquid is to be delivered.

The object of this invention is to provide the tube cannot be hooked or held in its upright position until the valve is lowered for closing the delivery port.

A. further object of the invention is to provide means for insuring the proper amount of liquid being placed in the can.

Still another object of the invention is to provide means for accomplishing the above objects and which can be economically manufactured and applied to existing dispensing cans as well as to cans in the process of manufacture.

The drawing illustrates an embodiment of the invention and the views therein are as follows Figure 1 is a vertical sectional view of a measuring and dispensing can embodylng the invention,

Figure 2 is a top plan view with a portion broken away,

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure 1 and looking in the direction of the arrows,

Figure 4 is a fragmentary view of the manner in which the flexible rod is hooked in upright osition in the conventional measuring and ispensing can.

According to the invention a dispensing can which has a port or outlet in the lower 1929. Serial No. 370,600.

portion thereofcontrolled by a valve which is actuated by a suitable operating device and which port communicates with a delivery tube or spout which can be tilted from its discharge position to an upright position. provided with a device to retain said tube or spout in an upright position and which com prises a movable member which is so arranged with relation to the valve operating device that when said operating device is in the'position which it normally occupies when the valve is open said movable member will be retained in a position to prevent the spout or tube from being operatively engaged by said retaining device, said movable member being movable to a position to permit said retalning device to operatively engage said tube or spout only when said operating device is moved to a position to close said valve. In the present drawings we have illustrated one embodiment of the invention in which the retaining device comprises a single member having at its outer end a hook-shaped portion to en age the spout and which is connected wit the valve operating device for movement thereby into and out of a position in which the spout cannot be operatively en gaged by the hook shaped portion thereof. It will be understood, however, that this particular embodiment has been chosen for the purpose of illustration only and that the retaining device may take various forms and the movable part thereof may be associated with the valve operating device in various ways.

In that embodiment of the invention here illustrated the can body 6 is provided with a bottom 7 having a port 8 therein and which said port is adapted to receive an elbow 9 while a flexible tube or spout 11 is connected to the outer end of the elbow and is provided on its outer end with a nozzle 12.

The port is controlled by a valve 13 which is carried by an arm 14 pivotally mounted at 16 in the support 17. The arm isprovided with an upright portion 18 for receiving a valve operating rod 19 which extends through the top of the can and is provided at its upper end with a thumb piece 21. The arm 14 is prevented from lateral movement by means of a bifurcated guide 22 fastened to the bottom 7 of the can.

The rod 19 extends through slots 23 in the guide member and this guide member is arranged to house a spiral spring between the wall of the can and the rod. while the slots :23 are provided with recesses 27 loruted at points near to the wall of the can so that when the rod it) is pulled backward through the slots 23. it may be pressed to the side and retained in such position so as to hold the valve 13 in raised position and the port 8 open.

So far the mechanism which has been deconventional and by reference to Figure 4, it will be seen that the nozzle 12 on the end of the flexible delivery tube is provided with a hook 28 which. when said tube is not in use, is adapted to engage the upper edge of the can to maintain the same in an upright position.

With a structure such as described and with hooked member such as shown in Figure 4, heppinis that the valve operating: rod

-tained in one or the other of the reces. s when the contents of the can have been dva med and the flexible member is moved to its uprightposition and hooked in such position by means of the hook In such an event, when the can is refilled with liquid, the liquid will flow into the tube and to a level on the same plane as the level to which the can is filled, thereby pr viding an excess amount of the liquid and utterly destroying the utility of the can as a measure.

In the use of the can it is usually held by the handle 29 and maintained in its upright pc ion, and in case the can has been filled with the valve open, and the flexible tube ll thus also filled, the movement or" the tube or spent to its lowered position. for delivery into a crank or other receptacle, will permit the liquid to be discharged therefrom as soon as the. outer end, of the tube passes below the upper level of the liquid in the can proper, thereby causing: a splashing or spilling of the liquid before the end of the nozzle has been inserted in the crank case or is otherwise in proper position for the delivery of the contents of the can.

To overcome this objection we have provided spout retaining device which, in the form here illustrated, comprises a rod 31 which, is connect-ed in any suitable manner at its inner end to the valve operating rod 19. This rod passes out through an opening" 32 located at any convenient place in the body ot the can and it is provided on its outer end with a hooked member 33 whose contour is substantially the same as the nozzle of the delivery tube, and when the parts are in the position to close the valve, such as shown in. Figure 1, there is just sutlicient clearance between the end of the hook, designated by the numeral 34, and the side of the can, as designated by the numeral 35, (see Figure 2) to permit the nozzle of the flexible tube to pass therebctwcen and fall into hooked relation with the hooked member 1 5.

\Yhen, however, the valve rod It) is retracted. as shown by the dotted lines in Figure 1. so that the valve 1;, is raised and the port 8 open, as also shown by dotted lines in Figure 1. the end of the hook ll will be drawn toward the body of the can or toward the point 35, as shown by the dotted lines at 34c in Figure 1, so that the space between these two points is insullicient to permit the nozzle to pass therebctwcen.

A sl ght jar of the nozzle 11% against the hooked member will ordinarily disconnect the operating rod 19 from its position in the recess 2%, but in any event. the one handling the can will at once be apprised of the fllt'l thatthe valve is open and will imnuulialcly close the same by disengaging the rod 111 from the recess 27 so as to hook the upprv end of the flexible rod ll or the nozzle 1;! in the hooked member 33.

The measuring and dispensing can ll()\\'ll in the drawing is merely for the purpose of illustratin; the invention and it is to be understood that various types of cans may be used and various modifications and changes maybe made without departing from the invention herein set forth and hereafter claimed.
