Application July 8, 1946, Serial No. 681,944

This invention relates to dispensing apparatus, and especially to apparatus for dispensing detergent material, such as paste soap.

It is known to provide apparatus for dispensing soap, or similar material, for washing the hands. Such apparatus is commonly arranged for operation by force exerted by the hand to deliver a small quantity of the material. Due to the fact that the force conveniently available in this manner is comparatively small, the material capable of use in such apparatus is limited to such as have free flowing characteristics as, for example, material in powder, or liquid form. Under many conditions, such material is quite satisfactory.

In many instances, such free flowing material dries out before it is used up entirely. The resulting caked material is diflicult to handle even when known mechanical devices are used to express the material from the container.

A material having satisfactory cleansing properties is preferably in the form of a heavy paste, possibly carrying some abrasive material. Such material, especially, cannot be handled readily by apparatus relying on manual pressure to deliver the material, and it has been the usual custom to supply such material in open cans or containers, from which it is scooped by the user's hands, as required.

This is a wasteful practice, as material substantially in excess of the quantity actually required will usually is taken. Furthermore, the material in the container is soiled or contaminated by contact with the users hands.

' It is an object of this invention to provide a dispenser for detergent material, or the like,

\ utilizing power, such as fluid pressure for the dispensing operation.

It is another object of this invention to provide apparatus for dispensing detergent material under pressure, and which is operable in a conventional manner by the user.

It i'sanother object of this invention to provide dispensing apparatus for detergent material in paste, or semi-liquid'form, which is readily operable in a conventional manner.

It is still another object of this invention to provide a dispenser for paste, or semi-liquid detergent material, having novel means for re newing the supply of such material.

This invention possesses many other advantages, and has other objects which may be made more clearly apparent from a consideration of several embodiments of the invention. For this purpose there are shown a few forms 1 Claim. (Cl. 222389) in the drawings accompanying and forming part of the present specification. The forms will now be described in detail illustrating the general principles of the invention; but it is to be understood that this detailed description is not to be taken in a limiting sense,.since the scope of this invention is best defined by the appended claim.

In the drawings:

Figure 1 is a sectional view, partly in elevation, of a dispenser incorporating the features of the invention;

Fig. 2 is a cross section, taken as indicated by line 2-2 of Fig. 1;

Fig. 3 is a fragmentary, transverse section of acontainer adapted for use with the dispenser of Fig. 1;

Fig. 4 is a detail section, taken as indicated by line 4-4 of Fig. 1;

Fig. 5 is an elevation, partly in section, of a modified form of dispenser; and

Fig. 6 is a plan view, partly in section, of the dispenser of Fig. 5.

In the form of the invention shown in Figs. 1' to 4, the dispenser is shown as comprising a --cylindrical shell 5, closed at its upper and lower ber 5-a, and a space 5-b containing the material to be dispensed, such material being a detergent.

material, orthe like, such as a heavy paste. Pressure is exerted on the material in the space 5-1)- by supplying fluid pressure to the chamber 5-a,

.1 so'that it will be discharged through a conduit 8 provided'with one or-more valves 9, when the valve or valves are opened.

-Referring in detail to the structure, it is conarranged so that a suitable discharge opening may be formed readily therein. For this purpose, an opening It may be provided in the bottom, and covered by a patch [5 secured exteriorly easily removed when desired.

The bracket 6 is arranged to mount the container Ill so that the body ll thereof forms the shell 5. The bracket 6 comprises an arm [6 arranged to project horizontally from a wall or on the bottom l3, as by soft solder, so as to be mosses other supporting surface S, to which it is secured, as by screws ll, engaging a vertical extension H! of the arm iii.

A pair of shouldered spacer rods 19 and 28, extending upwardly from arm I 6, support a head or closure member 2| for sealing and closing the upper end of the body ll, in lieu of the cover I2 which is removed when the container It) is mounted for use. Forthis purpose, the head 2| is provided with an annular flange 22 adapted. to enter the upper end of the body I I, and having an exterior groove 22-a for accommodating a resilient packing ring 23 of rubber, or other suitable material.

The container body H has an outwardly flaring lip i l-a for engaging the packing ring '23. Means are provided for urging the body- H upwardly to cause the lip iI-a to compress the packing ring 23 against the head 2 I. This means is shown as comprising an upstanding, exteriorly threadedhtubular member 24 carried. by the.-

Anut 27,, having a cylindrical extension Z'l-a.

is-threaded on, the member 24, the extension Zl-a being adapted to engage a circular recess. 28 in the bottom of a lower head 29. This lower head His in. the form of a circular plate and is of suitable size to fit readily within the flanged portion l3-a of the container bottom l3.

The arrangement is such that, when. the nut 21 is rotated to move upwardly on the member 24, the container 58 is moved upwardly to seal against the head 2!. When the nut 27 is rotated, to move downwardly, the container l moves downwardly below the'fiange 22, and then may be removed readily by lifting sufiiciently to cause flange I344. to clear the lower head 29-, and moving the container laterally from between the rods or posts I9 and 2D.

. The piston 7 comprises a flat disc 30 with a peripheral flange 3| of a suitable exterior diameter to slide freely within the shell 5. Suitable packing 32' is provided to prevent fluid leakage past the piston. A central hub 33 having anupwardly. directed tapped hole 34 is provided for-a purpose to be later pointed out. The piston T andpthe head}! cooperate to form the expansible. chamber. -a to which, fluid. is admitted by; the conduit 35, connected with an opening 33in thehead.

Since.- the; dispenser will, in general, be used; in.

wash. rooms, or the like, where waterunder' presv sure'isavailable, the conduit 35 will, usually beconnected to such water; supply. Howevencompressed air may be used if desired. In either case, a valve (not shown) will beprovided in the conduit 35to shut off the fluid pressure when desired; as, for example, to installa filled container. I0;

Itzwill be obvious that fluid pressure in chamber 5-a will. urge the piston I downwardly on the material in the space 5-D, this material be-- ing, as previously indicated, capable of flow'under theapplied pressure. 7 I

Since the member 24 and nut 21 are to provide the discharge passage for this material, an opening: 37. is provided extending through, the lower head 29 from the recess 28-. The opening M; in the container bottom 13 is arranged to register with port 3'! when the container is installed on the bracket 6, the patch l5 being removed before, installation. A gasket 38,. ac-

commodated in a groove 39 extending about the opening 31, serves to prevent leakage of the material between the lower head 29 and the bottom l3, the bottom l3 being urged downwardly against the gasket 38 by the pressure of the material in the container. Additionally, a gasket lfl is confined between the upper end of nut 27 and the bottom of recess 28.

The head 26 of the member 24 has an internal thread 26-11 for accommodating an elbow 4]. to which the conduit 8 is connected. This conduit 8 may have any desired number of discharge valves 9" thereon, two being shown by way of example, or a single valve may be secured directly to the head 26.

As clearly shown in Fig. 1, each valve 9 corn prises a tubular member 43 which the fluent material' enters freely. The member 63 has an upwardly facing valve seat 45, and a reduced tubular extension 45 forming the outlet. A valve memberfili. cooperateswiththe valve seat M to close the outlet 45, being urged to seat by the pressure of the fluent material. The valve member 46 has an operating stem 4? projecting outwardly through the outlet 45.

When it is. desired to obtain material from the dispenser, the' user places his hand beneath the valve 9 and pushes. upwardly on stem til, unseating thevalve- 46 and causing material to new through the outlet45. Upon release of-the stem, the valve d6 reseats and delivery of material ceases. Since the area of the valve is small, mod erate force suflices to open the valve, the pressure of the material immediately closing the valve. The material is delivered slowly, sincethe effective opening of the valve is small. This slow delivery, and the fact that the pressure of the mate rial urges the. valve to seat at all times, ensures against waste.

When the entire contents of a container have been used, the fluid pressure in chamber 5-0; is shutoff, and the nut. 27 is slacked off suliiciently to' allow the container IE to be removed. A bar or rod' is then screwed into the piston boss 33, and the piston l is removed. The cover l2 and the patch i5 of a filled container IE1 are then removed, the piston i inserted on top of the materialtherein, and the container placed on the lower head 29. The nut 27 is then operated to urge the container lip H-a to seal against the head gasket 23. The fluid pressure is then turned on, and. the dispenser is again ready for use.

An; ornamental casing 49 is provided for enclosing the, dispenser, being arranged to telescope oventhehead 2i, and extending to the bottom of the; bracket arm 16. A cut-out 49-a is provided atthe backiof the casing for accommodating the arm I 6. The casing 49 slides freely over the head 21, so that it may be removed and replaced readily when anew container l 0 is to be installed.

'In thernodified form of dispenser shown in Figs. 5 and 6, a cylindrical shell 50, having'a packed piston 5| slidable therein, is provided as before. The upper and lower ends of the shell 53 are closed, respectively, by heads 52 and 53' secured by through bolts 54 and rendered fluid-tight by gaskets 56 and 51. The dispenser is mounted on thehorizontal arm of a bracket 58, and secured thereto, as by a pair of the bolts 5 arranged to extend throughthe bracket arm.

Fluid pressure is admitted to the shell above the piston. 51 by a valve controlled conduit 59' connected with a suitable source (not shown). A valve controlled outlet 60 is also provided. A discharge outlet 6! for the soap paste; or

other material, is provided, and is shown as equipped with a single valve 9, although additional outlet valves may be provided, as in the first described form of the invention.

The soap paste is discharged under the ressure exerted by the piston 51, as before, but the shell 50 is filled initially, as well as subsequently, through a one-way pressure fitting 62, such as a conventional Alemite, or Zerk fitting.

When the shell 59 requires filling, the valve in the pressure conduit 59 is closed and the outlet valve 60 is opened. A grease gun adapted for use with the fitting 62 is then filled with the soap paste, or other material, which is forced into the shell through the fitting 02. This forces the piston 5| to rise, the fluid above it escaping through the outlet 69. Upon the shell 50 being filled as required, the outlet 59 is closed, and fluid pressure admitted through conduit This causes the piston 58 to exert pressure on the material in the shell 50. The fitting 62 automatically closes to prevent escape of any of this material, which can be discharged only by operation of the Valve 9.

The inventor claims:

In a device of the character described: a lower head; an upper head; a container having an open top and a bottom with an aperture therein, said bottom resting on said lower head, the upper head serving to close said open top of said container; a piston in the container; means for admitting fluid REFERENCES EDITED The following references are of record in the file of this patent:
