DISPENSER FOR LIQUID-soar AND THE LIKE.

Specification of Letters Patent."

Application filed January 31, 1914. Serial No. 815,662. j

To all whom it may concern Be it known that I, EvERE'rr E. BUSSEY,

a citizen-of the United Statesyand a resident of Malden, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Dispensers for Liquid Soap and the like, of which the following is a specification.

My invention relates to dispensers for liquid-soap and the like and more vespecially to devices of this character in which a small charge of liquid is delivered by the manual actuation of a valve located at the lower portion of the container.

The object of my invention is to-improve and simplify the construction of containers for liquids in the manner hereinafter set forth.

One embodiment of my invention is shown in the accompanying drawings in which- Figure l is a vertical central section of a dispenser for liquid embodying my invention. Fig. 2 -is asection taken on the line 22, and Fig. 3 is a section taken on the line'3fi3.

.In the particular drawings selected for more fully disclosing the principle ofmy,

' as separate from the reservoir, although it .3. Preferably three will be obvious that it may be made integral therewith. Any suitable means may be employed for attaching the neckto the reservoir, and-in the present instance I provide a nut 5 threaded to the neck for com pressing the rubber gasket 6 between the inner wall of the reservoir and said nut, a flange 4 integral with the neck being in engagement with the outside of the reservoir.

same is -a plunger 7 provided with one or more lateral recesses, pockets, orlpassages 8 for conveying a predetermined q'uantity or charge of' liquid from the reservoir to the delivery chamber or mor'esuch recesses 7 Located within the neck and having. a

sliding fit with the spire and the top of the are employed, so that the plunger may have three or more points of support on the interior wall 9 of the neck. This is desirable Patented Fee, 29, 1916.

because therebywthe plunger is kept in per- 1 feet alinement with the valve seatwithout unduly prolonging the plunger and Without lengthening the neck in which it reciprocates. Unless three or more such points of support are provided, the proper v seating of the valve 11 on its squared valve seat to close the lower end of the delivery chamber is not always 12 being often partially open. By means of my construction, however,

always squarely seated, leakage being thereby prevented. The delivery chamber is propossible, such seat-- -ing being at best uncertain the outlet' the plunger is always positively guided and the valvevided with an outlet 12 through which pro jects the handle 10 of the plunger, a rubber gasket 11, which surrounds the'handle just below its'juncture with the plunger, constituting a valve cooperating with a squared valve-seat 11 cut into the lower portion of the chamber 3.

. 17 surrounding a pin l6.which, if employed,

rises from the plunger, said standards 18 constituting means for guiding the plunger in its-reciprocal movements and the spaces between said standards ports through which the contents of the reservoir may flow into the upper'chamber or-cage formed by the standards the rim and the cap. As shown, the-spring is tapering in longitudinal section, the spires thereof being 'of progressively decream'ng diameter downwardly, so that. when compressed by forcing the plunger up to its full extent, the

spires will benested within the topmost plunger separated The valve seat preferably isform'ed by counterboring the upper part from the underside of the cap 15 by the thickness of the wire by which the spring is formed. 'This is advantageous as-it permits the use of a shorter neck.

In devices of this character it is desirable to deliver a' small quantity or charge of soap at a time in order to prevent waste and it is preferable to have the delivery chamber air-tight. As will be obvious, the plunger is normally held downward so that the outlet 12 is closed by the gasket 11.

The upward movement of the plunger is limited as aforesaid only bythe thickness of a single spire or coil ofthe spring 17 which surrounds the plunger pin. When the plunger is held on its seat, its upper away portions 13, 14, and upon the release of the handle, the plunger under the action of its spring, will be thrust downward and a charge of liquid thereby conveyed bodily from the reservoir to the chamber. The plunger is then again pushed upwardly as before and a second charge flows into the plunger passage. On the release of the plunger its spring again forces it downward and the liquid charge previously conducted into the air-tight chamber is forced or crowded by the incoming charge out of the chamber-past said valve seat, and expelled through the chamber outlet. around the handle and down along the latter into the palm of the hand. The handle in projecting through the outlet assists in conducting and guiding the liquid directly into the palm of the hand. Thus the repeatedoperation of the handle and its plunger aS described takes" charges from the reservoir and carries them bodily successively into the delivery cham her. After the first charge has been delivered it will not be necessary in obtaining the next charge to push the plunger upward twice, since a charge will always be in the chamber in readiness to be delivered therefrom on the first upward push of the plun- Heretofore. in liquid soap dispensers, considerable difficulty has been experienced from the drying and clogging of the delivery mechanism, owing, among other rea- 1 sons, to the fact that such mechanisms have been exposed to the air between operations. By my invention the discharging mechanism is not exposed to the air at any time excepting on the delivery of liquid therethrough since the mechanism is inclosed in the air-tight chamber and the ingress of air thereto is effectively prevented by these-a1- ing of the outlet end of the chamber by the plunger valve on the valve seat. As shown herein the liquid charge conveyed by the .rectly with the reservoir.

plunger passage 8 is not suilicient to completely fill the chamber surrounding the plunger, but there is a volume of air pocketed above the charge resting on thebottom of the chamber above its outlet. This constitutes a fluid seal beneath the upper valve portion of the plunger which closes the entrance between the reservoir and chamber, and efiectively prevents any leakage of liquid from said reservoir past said plunger into said chamber. As a result the same volume of liquid charge is always delivered from the chamber. lVhile herein both liquid and air are in the chamber it will be apparent that the seal would exist if either air or liquid were in the chamber. Any tendency to dry or clog the delivery mechaanism is further prevented by the fact that said mechanism is continuously surrounded and kept wet by the liquid in the chamber. If there should be at any time an-accu'mulation of dry soap exterior of the Valve seat in the annular discharge openings surrounding the handle it is automatically dislodged when the handle is moved upwardly for effecting a discharge operation.

It has been found in practice that devices of this. character areliable to leak because the valve on the plunger does not always accurately cooperate with its valve seat.

such number of passages 8 that the plunger will have at least three points of support on the interior of the neck, thereby insuring the accurate registering of the valve with its seat. It has also been found that reservoirs in liquid soap dispensers are liable to breakage due to temperature changes when the wall bracket engages di- Accordingly, in the present instance, I have provided a bracket 19 having a wall plate 20 at one end and a two- part clamp 22, 23, at the other, said clamp engaging the neck itself as distinguished from the reservoir, so that the contact will be between metal and metal as distinguished from metal and glass, as is the case where the bracket embraces the lower part of the reservoir itself. The clamp preferably engages the neck between the flanges 4, 21 and the two halves thereof are united by screws 24 threaded into the lugs 25, 26, or in any other suitable manner.

A dispenser such as described above provides a very advantageous construction; it is simple in construction and operation, cheap to manufacture and is not liable to get out of order. Y

While the dispenser has been described herein as applicable for receiving liquid soap, it will be readily understood that it may be used for delivering perfumery or other liquids or materials.
