This invention relates to liquid dispensing devices, particularly those 'of a' character" suitable for facilitating supply: of controlled amounts of oils, etc. 'Theinvention-will be understood from the following description, the accompanying taken in connection with drawing, in which Fig. 1 is a longitudinal sectionalview of one form of construction contemplated; I V

Fi 2 is a bottom view of theidevice' Fig. 5 1s a longitudinal'sectional'view of a modification; and

'Fig- ,6 is a similar view ofcanother modificationiy I i I In the drawing the reference character 0 designates a container, which ma be made up of tin platel or other suitable sheet material and which may vary somewhat in its precise form, but preferably will be'of square or rectangular cross section, .as more convenient for handling. Advantageously' the which iscompensating as container may .be assembled-0f a body sectionl, a top 2, a nozzle or spout '3 preferably of polygonal cross section, and a'bottom 4. The spout 3 is to form a valve-seat'ti against which may rest a valve 7 havin a \VfiShBlL' I-Of leather 3 7 prepared fiber or other desired material. The valve is carried on the end of'the rod 8 to length, as by being provided withcurvatures 9 or other means to allow. of a small'amount of longitudinal take-up for a purpose to be referred to more in detail hereinafter; and near the other end of therod is secured a ventvalve 10, ing rounded or enlarged end of the valve rod 8 and so as to project therewith through the vent openingin the bottom 4:. The ventvalve 10, as in the case of the spout valve 7,

, provided with aninturned or 1 lnserted flange member 5'wh1ch is shaped which advantageously may have a secursleeve 11 extending. to and embracing the lsprovidedwitha suitable washer face to member 4 which a holding bar 14 rides. This bar ;is swiveled on'the end'of the valve' rod 8, and while it may be so attached in several vari- I ABETH,"nEwJnnsnm-Arm DOUGLASS eflroivi'xms, or

coact with'the valve seat' l2. The bottom I has a cam-like projecting surface p p or ridge 13*(which maybe integral) against ous manners, a convenient. construction is i that represented in Fig. 3 in which place with the recessed'shoulders 15 embrac 'ing the enlarged end 'of-the rod. Another convenient construction is that represented I the bar isshaped up of; sheet metal andclosed in] in Fig. 4 in which a section ofalrod or tube 1a is centrally split and finally secured by being 'pressedup into engagement so asto enclosc the end of therod p With the bar 14 swung around on the cam ridge 13 into the diametrally-spacedodepressions 16the valve *rod 8 is allowed to slack jforwardly, and when inverted Tithe spout valve 7 is unseated and the container can be filled on-a suitable chargingde'vice. Similarly, in use, by inverting the container and swinging thebar' 14 around-into the depressions 16 the "oil or'other liquid-can @be discharged tothe amount desired. and the valve7 then be closed by. swinging the bar 14 around back upon the-Loam ric'ge until a tight. Tilt;willbenoticcdi that whil e .,the

sp'out'va'lve 7 is open the. vent-valve'lO is also unseated'so as topallow access of air to permit flow, but whem the spout valve is drawn lip-against itsi-seat the vent valve '10 'isalso drawn" upagainst its seat; and the containercan be set .UPI-IghiTOI'bG placed 1n any positlon without danger of leakage at either bottom 'or'spout: The compensating curvatures '9 in the rod-8' allow of sufficient I take up either way to-at all times insure the simultaneous seating of both valves.

Intheiform of constructionshown n Fig.

5 the cam-ridge -13"is provided onkan insert member. -17' set in additionally to. the bottom -member at, thus providing somewhat greater durability. I 1 t Inthe form shown in Fig. 6 the valve 7 is arranged to be automatically held open or unseated while in the filling machine. For this purpose the valve is provided with a pro'ection having a middle enlargement- 18 an surfaces tapering therefrom fore and aft. Spring finge s, indicated in dotted lines at 19, are arranged the socket of the filling machine and as the can is being placed in filling position ride up the front tapering surface and snap over the enlargement 18 and in the final position of the parts hold the valvelout from its seat. On completion of the filling operation, by swinging the bar 14 around on the cam surface the valve rod 8 is retracted and the grip of the spring fingers 19 is overcome and the valve is reseated. To allow some freedom of motion of the valve 7 when the valve-rod 8 is slacked forwardly, the valve 'may he slidably connected to the rod 8, as by an extension 20 having an elongated lateral projection 21 extending through the slot of the link 22 on the-end of rod 8 and headed over to prevent disengagement. This gives the desired'lnobility, and when the valverod S is finally retracted the valve is also properly seated.

We claim:

1. In a liquid-dispensing device, the combination of a container having a spout provided with an internal valve-seat and a bottom provided with a vent-opening, a valveseat internally of said vent-opening, a valve for coacting with said spout valve-scat, means on said spoutvalve whereby the valve may be held unseated, a vent-valve for coacting with the vent valve-seat, a compensating valve-rod carrying both said valves and projecting through said vent-opening, an external camridge on the bottom about said vent-opening and having diametrallyspaced depressions, and a holding bar swivelly mounted on said valve-rod so as to ride with its inner face on said cam-ridge.

2. In a liquid-dispensing device, the combination of a containerhaving-a spout provided with an internal valve-seat and a botin diametrally spaced depressions, and a ho iing bar swivelly mounted on said valverod so as to ride on said cam-ridge.

$3: In a liquidsdispensing device, the combiiz'ition of a container havingla spout provided with an internal valveseat and a bottom provided with a vent-opening, a valve seat internally of said vent-opening, a valve for coacting with said spout valvcseah a vent valve for coacting with the vent valve seat, a compensating valve-rod carrying both of said valves and projecting through said vent-opening, an external cam-ridge on said bottom having diametrally-spaced dcpressions, and a holding bar swivelly mounted on said valve rod so as to ride on said cam-ridge.

4. In a liquid-dispensing device, thecombination of a container having a spout provided with an internal valve-seat and a bottom provided with a vent-opening, a valveseat internally of said vent-opening, valves coacting respectively with said valve-seats, a compensating valve-rod carrying said valves and projecting through said ventopening, a holding bar swivelly mounted on said valve-rod, and cam means for positioning said holding bar.

5.
