IMPROVEMENT I FUNNELS.

The Schedule referred to in these' Letters Patent and making pan of the same.

To all whom it may concern Y Be it known that I, WILLIAM LEDMUN, of Bridgeville, in the county of Sussex, and State of Delaware, haveinveuted a new and useful Improvement in` Fuinnels; and l do hereby declare the following to he a tull and-correct description of the same, sufficient toenable others skilled in the class to which my invention apperta-ins to fully understand and construct the same, reference 'beinghad tothe accompanying drawings which make part of this specification,'and

in which f o l Figure 1is a vertical section` of my improved fun- Figure 2 is a perspective view, showing the attachment of the lower to the upper part; and

Figure 3-is a sectional bottom view of the upper ike letters ofreference indicate like parts in the severaligures. y l

The nature of my invention consists, first, in con-` structing a funnel in two parts, the tunnel proper and the spout, which are easily attached to each other or detached from each other for the purpose of cleansing;secondly,-i uthen1eans-of shutting oli" the ow of liquids, or letting the same on. A

A, in the drawings, represents the funnel proper,

. provided near its lowerend Iwith a straight vertical rim, B. Y r u 'lo the lower narrow end of the funnel A is secured a short metal block orpiece, O, extending outwardly to one side. Y u

On this extending part is as to cover the, opening ofthe funnel completely, and prevent the discharge oi' fluids from the same when the lever is in position, as shown in dotted lined in' 3, but when in position as shown in black lines,

saine figure, the lever 1s clear of the opening f the u funnel, and allows 4a free discharge of llui'ds from'the when the lever has closed the opening of the funnel,

the pin c catching in notch d, prevents the lever from moving further in that direction, and when the lever is moved free from the opening,othe notch d' hears against pin c with a like result.

The spout of the funnel is formed in a separate piece, E, having a straight vertical rim, F, titting snugly over rim B of the funnel.

`1n this rim F is forme-d an L- shaped slot, G, into which fits and slides a pin or projection, y, which forms one of the means of securing.

On the inside of rim B of the funnel, isv secured a pivoted alevel-,11), the inner shorter part of which is ot' a rounded shape, so

` bent spring, H, provided at its free end with a thumbpiece, I, which passes through the rim, as already shown in lig. 3. y

On the spring near its free end is formed a tongue, J, which passes through rim B and through rim F, and at a point opposite or nearlyl opposite to the slot G. By pressingon the thumb-piece I, the tongue J is pressed inwardly vand out of the corresponding opening in rim F. This forms the other 'of the means of The rim F has a. part of its circumference exserted, as shown in iig. 2,'

seeming the spout to the funnel.

to allow for the play of lever D, the lower edge ofthe ,rim B and the upper edge of the exserted part form'V ing a sort of slot for the level' to move in.

I provide the inside of the funnel A with projecting points, c, to ineasure certain quantities by, the projecting points being easier seen and kept in sight than lines or other marks engraved into the surface of the funnel.

The operation of my improved funnel is a's 'ollowsrl lhe parts all being connected, as in fig. 1, the spout of the funnel is placed iu or over the vessel to be filled, and the lever D moved so as toV close the opening of the funnel.,y rlhe liquid is then allowed to run from thecask or other vessel into the funnel, 2until the de` sired quant-ity, as indicated by the point a., has :been reached, when, on moving lever I) so as'to free the opening of the funnel, the measured liquid is allowed to flow through spout E into the vessel to he iilled. Should it become desirable to clean the opening of the funnel and the inner part of the lever, the spout E is removed from the funnel by pressing the thumb-piece v I, and thus releasing rim F from tongue J and giving spout E a short rot-ary movement around rim B, so as to bring projection g directly under the vertical part of the slot G, when, by moving spout E vertically from rim B, it will at once become detached.

The great advantage of my improved funnel is that it is formed in two part-s, by means of which it can at any moment b e `cleansed without trouble, especially where one funnel has to serve in measuring out dili'erent liquids. Its construction is simple and its manufacture inexpensive.

Having thus described my invention, v

What I claim as new, and desire to secure by Letters Patent, is i 1. A lfunnel constructed in two parts, A and E, substantially as and for the purposes set forth.

'2. In a movable funnel, the lever D,`when arranged between the funnel vA and spout E, substantially as and `for the purposes described.
