DISPENSING FLASK.

Application filed May 14, 1928. Serial No. 277,633.

hzly invention relates to improvements in dispensing flasks, and the object of my imp rovement is to supply for dealers and others a device of this class of simple and efl ectivc construction, adapted for receiving a measured quantity of a liquid and for d elivering the liquid into a container, the device ineluding), resiliently controlled means for admitting air into the base thereof when the same is inverted and such means brought into operative relation to said container, so that the discharge of the device is rendered smooth and trceiirom gurgling and at the moment and location desired, the air admittingmeans automatically returning to initial position when released from operating contact with the container.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accon'ipanying drawing, which is a central vertical longitudinal section of my improved dispensing flask as standing upright, unfilled.

Slight modifications may be effected in this invention without departing from the scope of the appended claims.

The numeral 1 denotes a glass receiving and measuring flask which may have a graduation or other mark thereon to indicate the upper level of a liquid deposited Within the flask to show the measure of the contents. The flask is preferably in the shape of a wide mouthed jar whose inwardly diminished rim 2 is shaped with an outer thread to mesh with an inclosing threaded basal part 3 of a top closure 4 ct metal or other suitable material which is formed with a central upwardly directed hollow conical open ended spout 5.

The numeral 7 denotes a metal open ended tube which medially traverses and is sealed in ap aperture 6 in the closure member 4, the lower part of the tube extending into and nearly to the bottom of the flask 1 but in spaced relation thereto. The upper part of the tube 7 is without the spout but somewhat below the upper end thereoii. The tube 7 is a centrally traversed by a rod 8 having a metal cone 9 fixed on its lower end to move in and out 01. the lower open end of the tube according to the up or down movements of the rod to more or less vary the area of the aperture therebetween. A nut 12 secures a leather disk 10 and a washer 11 to the rod 8 and the cone 9, and the disk 10 thus normally closes the lower end of the tube 7.

The upper end of the rod 8 projects above the upper open end of the tube 7 a short distance, and the rod is bent rectangularly toward the spout 5 at a little below the upper open end of the spout and then shaped with a terminal annulus or eye part 16 which loose 1y encircles the spout, the diameter of the ring being enough to allow the ring to move up or down a short distance about the spout without binding thereon. A coiled compression spring 13 is mounted around the rod 8 above the upper end of the tube 7, connected at the lower end by being hooked into a hole 14 in the tube, the upper end of the spring engaging the shoulder of the rod leading to the ring 16.

The flask having received a quantity of liquld, such as oil or other liquid after a removal of the closure 4, the latter may be replaced and the contents discharged into a container after the flask is inverted. Then the linger of the operator may be used to push upon the rod part 15 to compress the spring 13 while pushing the rod 8 a short distance to cause the closure elements 9 and 10 to open away a desired distance from the inner end of the tube 7, thus admitting air through the tube to the inverted bottom part of the flask, and preventing the forming of a vacuum therein. The contents will then flow smoothly without gurgling or splashing from the spout into the container in a stream modified in volume by the action of the operator in varying the air admission area at the inner end of the tube 7 An important feature of this invention is the provision of the ring 16 about the discharge portion of the spout 5. The operator, without soiling his hands, and holding the flask in one handonly as inverted, may discharge the contents of the flask through the spout by merely pressing the ring upon the 7 head of a vessel into whose receiving opening the end of the spout is inserted, or upon the rim of the vessel. As this leaves one hand of the operator tree, the free hand may be used for other purposes, such as holding up the receiving vessel, a lighting device, etc. A one handed person will thus be enabled to employ the device successfully, or one who is temporarily disabled in one hand.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is: i

1. A dispensing device, comprising in combination, a spouted receptacle for a flowable material, an air-admission tube ranged alongside the spout, sealin 1y traversing the receptacle to open near its otto1n,a resiliently controlled rod traversing said tube having a closure on its lower end to control the opening thereof, and said rod having a terminal part encircling said spout.

2. A dispensing device, comprising in combination, a receptacle for flowable material, a closure for the receptacle having an open end spout, an air-admission tube ranged alongside said spout, sealingly traversing said closure to open within the receptacle near the bottom of the latter, a rod traversing said tube and having on its inner end a closure for normally closing the same, the rod being bent atits upper termination toward the spoutQa-nd shaped with a terminalring loosely encircling the spout, and a coiled compression spring en aged between said ring terminatlon and e upper part of said tube.

8. A dispensing device, comprising in combination, a receptacle for flowable material of a liquid nature, a spouted closure mounted upon said receptacle, an air-admission tube ranged alongside said spout, sealingly traversing said spouted closure and extending into the receptacle, :1 rod traversing said tube having on its inner end a coiled closure body movable out of the tube to varyingly restrict the area of the opening of the tube, a ring formed upon the upper end of said rod, and means for yieldingly resiliently controlling the movements of said rod to normally hold said coned closure closing the tube.

In testimony whereof I aflix my signature.

JUSTIN C. HOWARD.
