To all whomfit 'm1-ay con-cera: p ,p y y y I 3e 1t knownthatl, `SIGMUND: LIPPSTADT, a cltizenof the United States,\rcsid1ng at New have invented` certain ,new and useful Iniprovcments in lliquid-Disponsors, of which the. following is aspeci'lication. p y Thisinvention relates to yliquid.` dispensers and isparticularly adaptedfor `use in `dispensing liquidsoap.` `It 'willbe apparent however that it is adapted foruse. with other liquids `besides soap.` Its objectslare to'provide simple and veffective means fordiseharg` mgupon the hands of' thc'userfliquld from a` receptacle, and italso lncludes means for regulating and ccntrollingthe"amount of liquid discharged at cach operation.

This cover isalso provided with an opening 4' `My discharging means .is simply placed upon the receptacle and extends into it from the top, and therefore it is not necessary to make openings orinlet inthe receptacle to receive the hwchanisin constituting'my invention. p l

The novel featuresand advantages of my ,device will be understood from the following description andclaiins.

In the accomian'infr drawinf's v--Fiofure 1 i .1 o l D is a cross section showing my invention;` Fig. 2 1s 4a plan view of Flgl; and Fig. 3 1s a detail perspectlve vlew of thepivot bearing for my dispensing pipe. v i

` In these drawings 1 represents a receptacle for liquid which may be made of any suitable form and of any suitable material. cover 2 made of any suitable materialfiits on top of the receptacle 1 and is provided with a illing opening closed by the screw plug 8.

adapted toreceive a casing 5 which casing has a semi-'cylindrical section 6, and which is provided with the bearing recesses 7 for pivotally sup orting y the pipe hereafter described. here isa second casing 8 similar to the casing 5and`fitting thereover, and this second casing is `preferably parts 9 and 10 for convenience in placing them in position around the ings hereafter described.

As will be seen by reference 'to the drawing there is a pipe extending throughthe opening 4 mounted in bearings thereinandcarrying a force `pump at its lower end' within the receptacle 1. This pipe lsmade up ofthe section 11 which may be made curved and orr namental as shown, having the'idischarge outlet 12 directedv forwardatthc prc1`ieran-l specification of Lectemratent. i "Applicationlledlune 11,

` gle for discharging soap or other liquid upon thehands ofthe operator. u

Within thecasings Sand 8 thereis a cylin- `drical horizontal section 13 which has trunnion's atits'ends fitting in therecesses 7 and` thusurnishing a pivot bearing for supportjing they-ipe.` `This cylindrical portion 13has `screwed into itsV lowerside in line` with. the pipe 11, apipe 14 which extends down into thereceptacle nearly to the bottom thereof,

i. and which is therebent at substantially right angles so as to be directed toward one of the side 'walls of the receptacle. 'lhispipe has `is secured the cylinder 16 of a force pump, and this cylinder has near its outer end inlet `openings 17. There is a partition 18 within `this cylinderand it isprovided with a ccntrall opening for the passage of liquid.` A piston 19 `works `within the cylinder passing' the opening 17l and it has on its inner side a rod 20`extending through the opening in the .partition 18 and havingan enlarged head 21 `which is adapted to close the openingin the partit-ion 18 when'the `piston is in its outer position, as shown in Fig. 1. A spring 22 partition 18 `and the inner face of the piston 19, thus tending to force the piston outwardly and to `maintain the valve 21 in Closed position.` On the outer side of the piston 19 there is a screw-threaded projection23which has mounted thereon the adjustable screw threaded cap 24 and the jam nut 25 which is intended to lock the cap 24 in any adjusted position.

Since the liquid dispensing pipe is intended `to turn in the bearings 7 it is necessary to provide a slot 26 in the cover plateorcasing 8, and a slot 27 in the casing 5, and it will be understood that the endsof the slot 26 will serve as strips for limiting the movement of.

*ortummg the pipe upon its p1v- In operation my device is placed with they end of the cap 24 near the side wall ofthe recptacle, and when the up er end of the pipe 11 is pulled to the left in ig. 1 the cap brought into contact with the wall of the receptacle, thus forcing the piston 19 inwardly,

and at the same time opening the valve 21.

`After the piston passes the openings 17,

theyenlarged screwthreaded end 15 towhich surrounds the rod 20 and bears against the which o enings admit the liquid to the inte'- `rior of t e piston, the liquid will be forced up through ipe 14 and ipe 11', and will be discharged iirom the out et 12 onto the hand of the user. This operation of turning the pipe and discharging the soap ma be performed by the user with the han on which -he Wishes to receive the soa or the pipe may be turned with one hand W ile the other is held in position to receive the discharge. It will be understood that since my force pump is submerged in the liquid the amount of liquid which would enter it and its connecting lpes would vary according to the heighto the li uid in the receptacle. It was to overcome this and to insure the discharge of a ixed and definite amount of soap at each operation that I made use of the valve 21 in the partition 18. After one operation of the piston or plunger 19 it will be understood that no liqnidi can enter the cylinder until the piston passes the openings 17 in its outward movement, and as soon as it lpasses these openings the valve 21 'is closed, thus reventing any of the liquid which enters tiie cylinder from passing beyond the partition 18 and into the f connecting parts, and therefore whethenthe receptacle is full or nearly empty the same amount of liquid will be in the cylinder ready for the next operation of the piston, and the discharge is thus accurately controlled. The

adjustable cap 24 also furnishes means for controlling the amount discharged at each o eration, and it rovides means for varying t at amount as esired'. This cap by turning upon screw threads on the extension 23 may be made to approach more or less nearly the wall of the rece tacle and by this means the distance to W lich the piston will be forced into the cylinder at any one operation of the pipe-may be controlled and regulated, and it is of course true that the distance which the piston enters the cylinder controls portedl by said cover, liquid orcing means carried by said pi e within the receptacle, and an operating e, ement connected to said forcing means adapted to make contact with the wall of the receptacle when the pipe is e turned on its ivot. 2. Inga device of the class described, the combination with a liquid receptacle, of a rou h said' cover therefor, a pipe leading throu h said cover into said receptacle and pivota y supported by said cover, a force pump having a civllinder carried by the lower end of said plpe t e iston rod of said pump extending toy war a wall of said rece tacle and adapted to make contact therewit when the pump is moved in onedirection.

3. In a device of the class described, the combination with a li uid rece tacle, of a cover therefor, a pipe eading tli cover into lsaid receptacle and pivotal y supported by said cover, a force pump having a cylinder carried by the lower end of said pipe the piston rod of saidpump extending toward a wall of said receptacle and adapted to make contact therewith when the pump is moved in one direction, and a spring tending to force l the piston-outwardly.. l .y

4. Ina device of the class described, the

combination with a pipe, of a force pumpY having a cylinder connected to the end of said pipe, thek said cylinder having inlets near its outer end, a iston working 'in said cylinder, means ten ing normally to force said piston outwardly beyond said inlets, and a valve connected with said piston for closing the inner end of said cylinder when the piston is in itsv outer position.

5. In a device of the class described, the combination with a pipe,'of a force pump hav-y ing a cylinder connected tothe end of said pipe, the said cylinder having inlets'near its outer end, a piston working in said cylinder, a partition in said cylinder having ,an opening therein, a rod extendingfrom theinner face of the piston and having an enlargenient at its end adapted to close said opening when the piston is at its outer position, and a spring surroundingsaid rod bearing upony said partition and tending to force the piston outwardly.
