SOAP-DISPENSING APPARATUS.

Application filed April 7, 1925. Serial No. 21 ,281.

-The object of the present lnvention is to provide soap dispensing apparatus adapted for mounting upon a wash bowl frame or cover in such manner that the supply of soap is maintained in a container disposed wider the surface of the wash bowl or the like, an ejection nozzle and an operating plunger being exposed above the bowl, the

, arrangement being such that upon detaching the nozzle and removing a holding strap for the soap container, the entire device may be lowered and withdrawn from the wash bowl or like device. 7 l i Other objects of the invention are to provide a device of this character which shall be positive in its action, simple in construe tion, readily constructed and disassembled, etc. A further object of the invention is to provide ejection means of a typeYin which the manually operated member is a plunger so formed, supported, and guided, that it cannot be operated by striking with the hand as in the case of the usual plunger-operated devices, which, when struck with a sudden blow, will eject the soap with undueforce so that it splatters. v I

The invention will be understood by refer ence to the accompanying drawings in which Figure 1 is a sectional elevation of an apparatus constructed in accordance with the invention and mounted in position;

.Figure 2 is a front elevation of the same;

7 Figure 3 is a transverse section on the line 33, Figure 1;

Figure 4: is a plan viewof the intake valve head and bowl valve, slightly enlarged.

Referring to Figure 1 of the drawings,

A represents'the horizontal portion of a.

lavatory top or wash bowl which may be, for example, such. as employed in Pullman cars. The soap container or receptacle is indicated at 1. It may be made of any suitable material, preferably of glass, and has secured thereto a flanged neck 2 upon which is adapted to move a flanged collar 3, the

interior face of the collar bein threaded so as to engage the threads of a neck 4 depending from the nozzle'head 5, the lat,-

ter being provided with a nozzle 6. 1 H

Nozzle head 5 has rigidly secured thereto a tube? closed at its lower end by valve head 8 shown in detail in Figure 4. Valve head 8 is threaded upon the lower end of tube 7. It is formed with a central aperture having a bevelled inner face, the aperture being normally closed by a ball 9. When suction is created within the tube, ball 9 is moved upwardly to permit the soap lying within container 1 to pass into tube 7 The ball is held in proper position within the valve head by means of a cage comprising the wires 10.

l/Vithin tube 7 is apiston 11, the piston being carried by a piston rod 12, which at its upper end is connected tov a plunger 12, the

plunger being provided with a central aperture or passageway normally closed bythe threaded cap 13, the aperture communicat ing with a' transverse duct 14 which is adapted to come in communication with the ports 15 formed in the side wall of the tube 12, whereby the container 1 maybe supplied with soap. In otherwords, when cap 13 is removed and the plunger moved downward a short distance to bring ports 14, 15

into communication, liquid soap may be poured into passageway 12 and thence into the container, 1. i i r y The plunger inits reciprocating move ments is held against turning and thus maintained in such position that duct 14 will always register with ports 15, by means of a guide pin 16, which enters guiding aper ture 17 in the nozzle head, The plunger is normally main-tained in upper position by means of spring. 18 which at its lower end engages the inner flange or wall 19 of tube 7, and' its' upper end engages the plunger.

In tube 7 below-the piston and above the ball valve, is a small outlet aperture communicating with a tube 20 of relativelysmall diameter,-the said tube communic'ating'with a duct 21, leading to the nozzle 6. The

nozzle 6 may be secured to nozzle head 5 in any suitable manner. For example, it may be threaded 1n the sald nozzle head and thus readily removed therefrom when it is desired'to remove the entire apparatus from the bowl A. Or, by unthreading collar. 3, the container 1 may be detached from the head 5 and the two units removed as sepa the piston head projects, protected by a ring 22 and to this ring is securedby rivets 23 in lavatory top or bowl A through which v desire to secure or other suitable means a strap 24 by means of which the container, and the dispensing apparatus as a whole, is held in position upon bowl A. 1 I the operation of the device, the plunger B is pressed downwardly withtlie-thumb or finger, which causes soap intermediate the piston 11 and the base of tube 7 to be ejected through small tube- 20, duct 21 and nozzle 6. hen the plunger is released, spring 8- wi-ll serve to raise it toinitialposit-ion,.carrying upward the piston 11, and, by suction, raising ball 19 and filling the baseo't the tube-Z with soap, ready for the next downward ejecting ncrement of the piston]. It will be understood that various. modifi cations may be made in the form and arrangement of the elements illustrated in the, drawing without departing from the spirit ofimy invention, what I claim and by Letters Patent being as follows? r r 1. A. liquid soap dispensing device, comprising anozzle head provided with a nozzle, the head formed with a chamber having-lateral guide walls, a hollow plunger mounted in; said. chamber and engaging the said walls,. the .plun-gerhaving a lateral outlet, a tube supported by the nozzle head and adapted-to receive the plunger, a piston carried by the plunger and movable withinthe tube, a. soap inlet and a soap outletin the tube, apassagew ay aiiording communication between the outlet and the, nozzle, the tube being formed with an Outlet normally below the outlet of the plunger,

the two outlets coming into register when the plunger is depressed.

2. A liquid soap dispensing device, comprising a nozzle head and nozzle, the head being formed with a chamber having lateral guide walls, a hollow plunger mounted in said chamber and engaging said walls, the plunger being provided with a transverse outlet, a tube carried by said head and adapted to receive said plunger, the tube being provided with an outlet adapted to coast with the outlet of the plunger, a piston caried by the plunger and movable within the tube, a soap inlet and a soap outlet in the tube, and means-permitting the hold-in e zle, and means for-connectingthenozzle head and the receptacle,-the head being formed with a chamber, a plunger mounted in said chamber for endwise movement, a tube, a

piston ooeliatcd, b I said hun er and mov- ,l l Q as able within the tube, a passageway leadthroug-h the plunger and communicating with the receptacle whereby soap fed into the plunger-may pass. intothe recepta cle, asoap-inlet and a soap. outletinthe tube, and. means permittingthe passage of soapv from said, outlet to the nozzle. 4. A liquid soap dispensing; device, comprising a nozzle head and nozzle, the head being formed with a chamber having lateral guide walls, a tube communicating with said ehainbeiy a hollowplungei mountedin said chamber andprojecting into the tube, the plunger having a latera= l outlet duet normally closed by the walls. otthe tube, an outletv duct in. th.e tube, a spring normally mg the plunger sothat its outlet duct is above the outlet duct ofthe tube, apiston operated bysaid plunger and movable within the tube, a soap inletiand outlet in the tube, and means permitting the passage of soap, from said outlet.towthenozzl'e. I

A liquid soap device, comp i ing a nozzle headqand nozzle, the, head being formed with a chamber having lateralfguide walls, a plunger mounted in said chamber and having 'endwise movement thereiinna passageway formed in the, plunger, said passagewaybeing normally closed by a removable cap, a tube receiving said plunger and having an outlet passage adapted to communicate with thepassageway of the plunger when the latter is given an endwise movement, a spring adapted to hold the plunger in upper position, a piston car ried by the plunger and movable within the tube, a soap inlet .and outlet iuthetube and means for permitting the passage of soap from the outlet to the nozzle.
