V Y E" Hatented dugg. S1, llle Application led September 3, 1919. Serial No. 321,418.

To all fic/om t may concern Be it known that we, lmtns lll. Jones and FRANK C. Nrnv'roN, citizens oi? the United States of America, ano residents oi' Syracuse, in the county of Onondaga, in the Sta-te ot New York, have invented new and useful improvements in Funnels, of which the following, taken in connection with the accompanying` drawings, is full7 clear, and exact description.

This invention relates to certain improvements in bottle lillers in which a tunnel having a reduced end adapted to be encircled in the bottle is provided with means for automatically cuttingoff the flow oi? fluid from the 'funnel to the bottle as the latter is filled, the object being to avoid the dangers and waste from overflowj and at the same time to enable the operator to retain in thev tunnel any excess liquid over that which is required to properly lill the bottle( Other objects and uses relating' to specific parts of the device will be brought out in the followingv description:

In the drawings,-

Figure l is an elevation of my improvedbottle liller.

Figure 2 is a vertical sectional view of the same and a bottle into which its reduced ends are inserted.

Figure 3 is a sectional. view or" a modified form of my filler and of a portion or the bottle rear y 'for lilling. j

Figure l is a detail sectional view similar to Figure 3 except that the tloat is tubular and closed at the top for the trapping' ot the air therein by the risingv liquid, the bottle being' omitted.

Devices olf this character are pzu'ticularly useful in transforring` liquids from larger to smaller recejitacles, as for example, in drug; stores or analogous pl aces where liquids are lrequently 'transferred from largo stock bottles to smaller bottles7 the invention be'- ing adapted to prevent overflow oi' theliquid 'from the smaller bottle as it is poured into the funnel 'from a larger bottle so that the operator may determine Yfrom the level of the liquid in the hopper whether or not the bottle is iilled, such condition being` indicated by the rise of the level of the liquid in the funnel which is always opened to view while filling the bottle.

As illustrated in Figures l and 2, the lilling device comprises a hopper-shaped tunnel -l having` a reduced portion Q* and a still further reduced portion 3 the latter being provided with a flange -l-- some dis- 'tance below the reduced portion 9fand in lined relation to the body of the tunnel. Surrounding the reduced portion 3- below the flange i is a rino; or plate -5- of greater diameter than that of the mouth of the bottle as -AH u `son which it is adapted to rise when the funnel is placed in operative position for filling the bottle., @ne sideoi the ring;` is provided with a post -6 passing through an aperture 7- in the adjacent portion ot the flange -4, the upper end of said post being enlarged to form a head -8- above the flange -'lto allow limited vertical'rnovement of the plate -5- relatively to the lange when the funnel is lifted away from the mouth ot the bottle as shown in Figure l.

llfhe opposite side oit the plate provided with an upstanding` flange 9 having an aperture -r-lOvfor receiving` the adjacent portion ont a weighted arm u-ll-. This arm -llis pivoted at 12- to an upstanding flange 1B-e on the. saine side of the reduced portion fas the upstanding flange -9- ot the plate -5-, the inner end ot said weighted arm being provided with an aperture 14,-- ior receiving the upper end oi a vertically movable rod -I 5- which is enlvarg'ed'at the top to just above the adjacent portion of the arm llb4 to limit .the downward movement of the rod -l5-.

A tubular ioat -16- is provided with a' tapered upper end -17- constituting a valve which is movable into and out ot' engagement with a valve seat M'lflon the lower end of the tubular extension l of the hopper to control the dow ot the liquid from the hopper to the interior oit the bottle.

The upper end oit the tube -lGw is closed by the valve 17- while the lower end ot the same tube is opened so that as the liquid level in the bottle rises, it will trap the air in the tube nl6- and cause said tube to iloat.

This tubular loat is provided with lateral apertured lugs M19- tor receiving the rod -15-, the latter having its lower end enlarged to 'form a head or limiting stop to limit the downward movement of the float when the head at the upper end is resting upon the arm -l1. rlhis rod, therefore,

serves as a guide for the tubular float 16-v j to register it with the outlet or valve seat li8 This float is also provided with a central upwardly projecting stem 4-90v extending through a central aperture in a perforated disk 21- which is seated `in the bottom of the reduced portion -2 near its junction with the reduced portion -3-.

The upper end of the stem nO-- above the plate 2lis provided with a limiting stop Q2- which is adapted to engage the upper face of the plate --21'n toadditionally limit the downward movement ol' the float -16- away from the valve seat -l8-. v

lt will be observed upon reference to f`1gure 2 that the rod 15- .and upstanding flange -9 of the plate M5* engage the weighted arm *llat opposite sides ol its pivot -12-, the weight of. said arm be# ing preferably secu-red to the outer end of the arm -11- beyond the upstanding lllhen the ller is lifted from the mouth of the bottle so as to disengage this platev weight of the tubular float 1G- and parts the upstanding flange -91 carried thereby with suliicient force to close the valve -17v against theJ seat -18 and to thereby retain any liquid which may remain yin the funnel against' further `discharge. g I

On the other hand, when the Edler f placed lupon the mouth of the bottle with the plate -5- resting thereont the weight of the entire filler is suiiicientto elevate the plate -5- until it bears against the under side of the flange lby which operation exerts a lifting action upon the weighted end of `the lever 11- thereby depressing the inner end of said lever and allowing the float .-16- to drop away 'from its seat which in turn allows the liquid to iowv through the perforated plate -21- and reduced portions 2; and --8- of thevfunnel into the bottle -A-- i v 4The weight of the float m16- and its counterweighted lever -jllis adjusted so that bythe time the liquid level has approached suliiciently close to the mouth of the lbottle to fill the same without overflowing, it will have elevated the float 16- independently of the weighted lever sutliciently to close its valve -17 against the seat `18 thus automatically prei/renting further discharge of the liquid from the funnel into the bottle.

The bottle now having been filled, the tunnel withthe remaining` liquid therein is litt ed from the mouth of the bottle while at the vsame time the weight kof the outer end of the arm l1- and plate 5* will cause the elevation of the inner end 'of the lever against the upper head of the guide rod l5- tok keep the valve closed while the funnel is being removed from the bottle whereupon the residue liquid in the hopper may be restored to the original receptacle.

In Figure 3, l have shown a modified construction of liller consisting of a funnel -1- having a reduced portion --Qfat its apex provided with suitable outlets -3-, the upper end of the tubular eXtenlarged annular ange 25- adapted to raise upon the mouth of the bottle as A- when the filler is adjusted for use, the lower end of said tubular member'HQlbeing provided with a transverse partition -2--- A fioat -27 of cork or other suitable material is provided with a centra-l lengthwise reinforced stem w28@ extending lbeyond the opposite ends of said float, the upper end of the stem being provided with a valve -29- for cooperating with the seat -18- to prevent the discharge oil' the liquid from the funnel when the 'latter is removed from the bottle.

The lower end of the stem -28 is guided in a central aperture 7 30- in the partition -QG-and is provided with. ad-

in spaced relation vertically to engage respectively the upper and lower faces of the j partition -26 allowing a limited vertical movement of the stem and its float Q7- suiiicient to permit .the upper end. of the float which constitutes a; valve to close against the seat' -23-- lhen thel float is elevated by the rise of the level of the liq- .uid in the bottle the partition and side walls of the tubular member -2l are preferably perforated to permit the entrance of the liquid of the bottle into said tube for ylifting action upon the float to close it against the valve seat 423, it being` understood that the weight of the float is adjusted so that it will close against its seat 23 when the level oft the liquid approaches the mouth of the bottle and Ibefore the liquid overflows.

rlhe reduced portion -QQ is provided with an annular flange 33g against which the upper end of the tubular -member 2l abuts when the funnel is placed in operative position upon the bottle with the plate 2liresting on the mouth thereof.

Under these conditions the bottle being empty, the upper stop 30- on the red -28 will rest upon the upper face of the so as to hold the valve -29- and upper end of the float 2T- slightly away from their respective seats .-18- and QSC- to establish a free opening for the liquid from the hopper into the bottle.

New, it the liquid is poured into the hopper it will, of course7 flow into the bottle past the opened valve and when the level of the liquid approaches the mouth ot the bottle betere it overflows it will. lift the Hoa-t Q7- and its stem 2&3 sutliciently to close it against the valve seat 223- to prevent further llow of the liquid 'from the `funnel to the bottle, it being understood that the lower stop -2lis adjusted with su'lllcient clearance to allow the closing of the float.

lil/Then the bottle is thus filled the tunnel may be lifted therefrom which allows the weight of the tube *242- to slide along the reduced portion -2 away from the flange -33 and causes its partition 2G- to engage the stop -3l-` and close the valve 29 against its` seat -18- to retain any residue liquid in the funnel while` the latter is being removed from the bottle.

ln Figure il which is somewhat similar to Figure 5, the lloat consists of a metal tube -073- open at the bottom and closed at the top to permit the rising liquid to trap the air therein, said air containing float being balanced in such manner as to cause its upper end to close the outlet passagev from the hopper -lwhen the bottle is substantially filled.

lVhat we claim is:

l. In a bottle filler, the combination of a funnel having an outlet tube adapted to be inserted in the mouth of the bottle to be lilled and provided with a flange', a plate movable lengthwise or" the outlet tube at the underside of the flange for engagement with the mouth of the bottle when the filler is placed in operative position thereon, said plate being removed toward and against the llange by said engagement, a float valve for opening and closing said outlet, means for automatically closing the valve when the filler is removed from the bottle, and means actuated by the plate for operating the first named means to allow the valve to o-pen by its own weight when the ller is supported upon the bottle, said loatfvalve being operable by the rising ot the liquid in the bottle to close the outlet independently ot the first and second named means.

2. In a bottle filler, the combination of a funnel having an outlet tube adapted to be inserted in the mouth of the bottle to be lilled, said tube being provided with a flange, a plate loosely attached to the lian e for engagement with the mouth of the bottle when the filler is placed thereon, a Floatvalve for opening and closing the outlet and adapted to open by its own weight and to close by the rising of the liquid in the bottle when the filler is in operative position, and means including a weighted lever fulcrumed on said iange for automatically closing the float-valve when the filler is removed from the bottle, said plate having means for engaging and operating the weighted lever against the action of the weight, to allow the valve to open when the filler is in operative position on the bottle.

In witness whereof we have hereunto set our hands this 27th day of August 1919.
