Specification forming part of Letters Patent Non. 2l 1,352, dated January 14, V1879; application filed November 3o, 187s.

To all whom fit may concern.:

Beit known that I, GILLoUs B. SMITH, of Bath, in the county of Steuben and State of New York, have invented certain new and useful Improvements in `Measuring-Funnels; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification and in which Figure '1 is a central vertical section of my improved measuring-funnel, showing the mouth of the eduction-tube closed by the valve. Fig. 2 is a similar view, showing the ,valve removed from the mouth of the eduction-tube; and Fig. 3 is a top view of my improved funnel.

Gorrespondin g are denoted by similarletters of reference.

My invention appertains to certain improvements in measuring-tunnels; and it consists of a spring attached at one end to the handle of the funnel, and following the curve of said handle; secondly, of a spring attached at one end to the handle of the funnel, and following the curve ot' said handle, having a slot, which receives the upper end of the valve-stem; and, thirdly, of a concaved` collar, secured to the inside of the funnel near the mouth of the eduction tube, substantially as hereinafter more fully described and claimed.

The object of my invention is to provide the trade with a cheap and efficient measurin g-funnel, the valve of which can be easily and readily controlled by the operator.

In the annexed drawings, A marks a suitable frame supported upon legs a, and provided with a graduated scale or bar, B, with or without lugs b. Firmly secured to the handle C, preferably to the under part, is a spring, D, which extends upwardly and follows the curve of said handle, its free end being provided with a slot, which receives the upper end of the valve-stein E.

Attached to the top of the valve-stem E is a thumb-piece, c, having a bent portion, c',

parts in the several gures' which `catches under the spring-hook-F, secured to the funnel. The valve-stem E extends down into the funnel A under a confiningplate, Gr, and is hinged to the valve E', preferably made of a rubber base, surmounted by a metal cap.

Secured to the inside ot' the funnel near its bottom, and on the side opposite to the conlining-plate G, is a concave collar, H, which, when the valve is forced down over the eduction-tube I, holds thevalve upon its seat and completely closes the said eduction-tube. eduction-tub'e I is fluted, as clearly shown in Fig. 1, to allow the escape of air from the jug or other receptacle as it is being iilled from the funnel.

When it is desired to close the mouth ofthe eduction-tube Iin order to iill or relill the funnel, press the valve-stem down by means of the thumb, `pressing on the thumb-piece c until the projection c is caught and held by the spring-hook F, when the valve E will be pressed and held tightly over the mout-l1 Aot the eduction-tube I by the concaved collar H and lsaid spring-hook F, as clearly shown in Fig. 1.

To allow the contents to escape `from the funnel, press with the thumb on the springhool; F, when the projection c will be released from said spring-hook, and the spring D will draw the valve from over the eductiontube.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a measuring-funnel, the slotted spring D, secured to the outside of the handle and extending inwardly, in combination with a valve-stem and a spring-hook, substantially as and for the purpose set forth. i

2. In a measuring-funnel, the slotted spring D, secured to the outside of the handle and extendinginwardly, provided with a thumbpiece, e, and projection e, in combination with `a valve-stein and a spring-hook, substantially as and for the purpose set forth.

. 3. In combination with a funnel, A, provided with the con caved collar H, plate G, and

spring-hook F, of the hinged valveE, valve- 1 The bent projection e', spring D, andl rIn testimony that I claim the foregoingas my own I hereunto affix my signature 1n presence of two witnesses.
