Description

Cf/duurt i gisten @anni i. Toall whom itmay concern;

:Be it known that I, CARL RUF, ofthe city,

` new and usefulinprovonient in Funnels; `and I do hereby declare the` following to be a full,`clear, and exact description thereof, which will enable those skilled i in the art to inake and `use't-lie saine, reference being had to the accompanying drawiugforining part ol `this specification, `which drawing shows` my improvementinverticalsection.

".lliis 'invention relates to fuunels lbiaconductiug `liquids into bott-lcs' or other vessels, and 'consist-sin constructing and coinbining't-lie funnel with a float lin such a mannerithat the nozzle of the funnel is automaticallyelosed by the ioat4 when the bottle `is liquid arrested, and-the'funnel can then be removed and applied to a fresh vbottle or vessel without spilling theliquid left in it. i i

The letter A designates the funnel, whose nozzle, i B, is shown inserted-into the mouth of a bottle.`

The funnel A and its nozzle Bare surrounded by a jacket, C, open at top'aud` bottom, inelosing a space, 1), througl'i which air is free to pass. p i l The jacket is attached "to the funnel by suitable bracesy f They letter E designates a tube, supported centraliy in the funnel iu` a skeleton` or perforated' dial nel.

TheI top ofithepfloat hasa packing, I, composed uffa ring vof `rubber or` other suitable material, s0` arrangedthat, `when the `float rises up to the nozzle, its packing 4strikes the end of the nozzle, form-- ing a `valve, ofwhielrthe end ofthe nozzle is the seat.

` f yIll/'IPRovEii/inur In PUNNELS;

I i i The isdiedul referred YU11-n these Lettera' Patent andv making rai-t of the same nel is pushed into the mouth of a bottle, the ends of the springs are brought against theutsile of the nozzle or its jacket, so as to press against the elastic.

sleeve,`whicl i is 'thereby kept in place while the nozzle is'pushed into the neck of the bott-le 'to thereqiiire'd extent.

The top of the stein G'of the float is pivoted to a lever, M, which turns on 'a fulcrum, N, arranged at the end of a` bracket, O, extending from the upper end of tube E. A

l" is ainovable weight, which I arrange to slide freely toaud fro upon the lever M, so as to cause it to complete its vibration on its-fulcrum after the risi ing of the lloat has'disturhed the equilibrium of the.

'pai-ts. i f

The end oi` the longer arin of lever M is provided with a stop, Q, which arrests theweight when it; ar-

rives at that point, and the end of its shorter ai-in is Abentiip at right angles, and receivesan adjusting'- sei'ew, It, by` which theI position of the weight with' reference to the fulerum N is regulated.

At the bentz'end of the lever, over the adjustingscrew R,`I have arranged a thumb-piece, S, by means of whicliI push down the shorter end of lever M, so as to bring it to the position shown in the drawing,

'when' thev weight P will slide, by gravity, along the -lever to a position past the fulcrum N, where it keeps the float depressed and away from the end of the nozzle, the adjustment ofthe Weight being so regulated .that-the preponderance is slight when the weight isat th'e'shorter end ofthe lever, and, therefore, a slight upward movement of the oat causes the lever M `to -turn on its fnlcrum, and raise its-shorter end, and de-l 'press its longer end,'.when the 'weight slides down tothe descent of the shifting-weight, .whereby the nozzle.'

or discharge-end of the funnel is closed, so that any liquid remaining inthe funnel 'is held there, and the funnel can be removed to a fresh bottle without lia- This act-ion of the apbilityof spilling its contents. paratus is automatic, and it takes place without any `otherattention on the part' of the attendant than the raising of the longer arm of lever M, when the funnel is applied to a fresh4 bottle or vessel, so that the wei ght may slide down to the shorter arm of said lever, where it remains, just counterbalancing the weight of -thc longer arm, and keeping 'the nozzle of the funnel open iintl the risingof the heat reverses the lever. As the liquid enters the bottle or vessel, the air eseapestlierefrein freely through the air-space D.

The perforated diaphragm F prevents the passage of foreign substances through the funnel, and thereby facilitates the fillingpf bottles or vessels in a proper manner, and preserves the float and nozzle from obstructions.

llie nozzle of the funnel can be made with a screw or sliding joint in such a manner that its 4length can be' increased or decreased, or the oat can be screwed up or down on its stem, or both can be, in this manner, made adjustable, it' deemed necessary.

NVhat I claim as new, and desire to secure by Letters Paten-t, is

1. The combination, with a funnel, of a dont-valve, for automatically retaining the contents of the funnel, constructed and operating substantially as described.

2. The combination, with a funnel, of the springs K K, substantially as described.

3. The perforated diaphragm F, supporting the tube E, in combination with the funnel A and jacket G, substantially as and for the purpose described.

4. The vibrating lever M supported on the funnel, as described, in combination with the {lont-valve H and stem G, substantially as shown and described.

' 5. The combination of the float-valve and stem with the lever M and its movable weight P, substantially as described.
