ERWIN D. SCHAFER, OF WALNU'IPOR'I, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO WESLEY MOFARLAND, OF WALNUTPOR'I, PENNSYLVANIA.

AUTOMATIC VALVE FOR COMBINED MEASURES AND FUNNELS".

SPECIFICATION forming part of Letters Patent No. 748,988, dated January 5, 1904.

Application filed July 11 1902. Serial No. 115,116. (No model.)

To ctZZ whom it may concern.-

Be it known that I, Eawm D. SCHAFER, a citizen of the United States, residing at Walnutport, county of Northampton, and State of Pennsylvania, have invented a certain new and useful Improvementin Automatic Valves for Combined Measures and Funnels, of which the following is a specification.

My invention relates to a new and useful improvement in automatic valves for combined measures and funnels, and has for its object to provide a measure and funnel combined with a valve which will automatically close the spout of the funnel when the apparatus is raised from out of the vessel into which the liquid is being poured.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective view of my device, and Fig. 2 a vertical section of the same.

In combined measures and funnels as now used the valve, which is adapted to close the spout of the funnel, is connected with a lever which is operated by the hand of the user, and the user depresses the lever when he wishes to open the valve and releases it when he wishes to close the same.

In my invention I do away with all improvements and make the operation of the valve entirely automatic.

A represents the cup or measure, and B is the spout leading from the lower end, which forms it into a funnel. O is a conical valve adapted to seat over the upper end of the spout B, where it enters the cup or measure A, and extending downward from the valve 0 through the spout B is a rod D, and secured to the lower end of the rod D is a crosspin E, which extends through the slots F, formed through each side of the spout B, and this pin E is then secured, by riveting or otherwise, at each end to a sleeve G, which is adapted to slide upon the outside of the spout B. Upon the upper end of the sleeve G is formed an annular flange H, and when the spout B is inserted in a bottle or other vessel into which the liquid is desired to be poured the flange H will come in contact with the rim of the bottle or vessel surrounding the mouth, and this flange H will thereby be pushed upward toward the cup or measure A, as shown in dotted lines in Fig. 2, and this will also raise the pin E, rod D, and valve 0 until the limit of the slots F is reached. The valve 0 will then be raised from ofi its seat, and the liquid contained in the measure or cup A will flow into the bottle or vessel; but as soon as the bottle or vessel is filled to the desired height the cup or measure A is raised from out of the bottle, and as soon as the flange H is removed from the bottle the valve 0 will instantly reseat itself on account of its own weight and the weight of the sleeve G and flange H, thus cutting ofi the supply of liquid as soon as the apparatus is raised. A collar Zis interposed between the spout and measure and is flared over on the measure to form a valve-seat for the valve 0.

For the purpose of allowing the air to escape as the liquid passes into the bottle or other vessel the flange H may be formed with radial corrugations, as shown in Fig. 1.

The advantage of my invention is that I do away with all levers and rods inside of the cup or measure, and thus do away with the liability of contaminating the liquid by the corrosion of such parts, and besides it does away with the necessity of keeping such parts clean, and also greatly reduces the cost of the article, and by simplifying it to a single gravity-valve there are no parts to become damaged or get out of order.

Of course I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing 5 from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is A measure having a spout leading from its lower end, said spout having slots, a sleeve :00

having a flange at its upper end, said flange being radially corrugated from the sleeve to the periphery of the flange, a cross-pin scfixed my signature in the presence of subcured t0 the sleeve and slidable in the slots scribing witnesses. of the spout collar interposed between the spout and nieasure, said collar being flared ER'WIN SGHAFER' 5 to form a valve-seat, a. valve on the seat and Witnesses:
