Specification of Letters Patent.V Patented Jliizbj-I'Biz Application iled Septemberl, 1908. Serial No. 451,167.

To all whom it '1mg concern:

Be it known that I, OHAnLns WADE, a citizen 'of the United States, residing at -East Orange, in the county of Essex and to improve and simplify apparatus of this class, and attain the discharge of the soapy liquid in as convenient and positive a manner as possible. V

In carrying out the invention I provide means by which the soapy liquid 1s positively acted upon in its ejectment from the reservoir, not .depending on gravity for its impelling force atanywstawithe-operation. I 'considerthis an limportant characteristic of the invention, 'as the liquid is sometimes thick and viscousan'ddoes not run freely through narrow passages where there is no other impelling force than the slight pressure due to the weight of the small fluid column available I make use of a. form of pump mechanismhaving valves,

and I further provide a form of automatic sign'1 designates a receptacle or vessel conor check valve for controlling the` inlet opening ofthe reservoir. I haveillustrated specially constructed valves -havingspecial advantages, 'as will 'be later more fully set forth.

Having these various and other objects in view, Imy inventionconsists'in -thcieatures of construction and combination as herein. ,after setfforth and claimed.

In the drawings: Figure 1 is a side elevation I embb ying the principles7 of myinvention; Fig. 2 isa detail sectional view of the valve which controls the 'inlet or feed orifice, and

Fig. 3 is a similar viewjshowing a slightly modifiedconstruction.l

Referrin .to'the drawing in `:which like parts are eslgnatedby the same reference veniently made of glass-.and insetand ce.d

artly in section,'of a soap dispenser screws 4. Vtithin the base 2'is contained a, pump mechanism for ejectmg the soa-py` liquid.

The rec'eptacle l has an opening 5 at its upper end in which' is received a small metallic or other cage-6 adapted to contain and guide the inlet valve. I make the cage 6 with a flange or shoulder 7 adapted to con-' tact with the interior surface of the recep tacle 1 around the opening 5. The upper ex# terior portion o'f the cage 6 is threaded to receive a nut or collar 8 which can be f screwed down on the cage so as to coperate with the fiange 7 and firmly hold the cage 1n its place. The cage 6 is of generally 'tlrimble shape, closed at its lower end 9 and having slots or openings 10 adjacent thereto' which establish a free communication to the interior of the receptacle l.

lLdesignates a. ball or other valve supported within the cage 6 and impelled upward by a spring l2. I have sho'wn a cupshaped valve l1 and a form ofspring -12 having a reduced end 13 whichventers the interior ofthe cup 1l so as to retain the same in its central position'.

14 designates a cap having an interior threaded portion l5 adapted to screw upon the upper threaded extremityof the cage 6 It is evident that when the cap or coveu 1st 1sscre\ v e dinto place, the receptacle4T is given a imsned and ornamental outline, and

at the saine' time a convenient valveiseatjs rovided., l `fIhe soapy liquid maybe' supplied 'y pouringit into the valve o erung 16 from a vessel having any suitable rschargespout, the valve 11 being depressed into its cagel in this actionlV base chambered or recessedftrans'ver'sely inward from its exposed side'withfia cylindpial bore L8 which constitutes the barrelpr cylinder oftthe pump.

rointhe pm p bore 18 into the receptacle j 19 designatesal passage extending upward 1, and through which the soapy liquid may enter the pump chamber.

20 designates a plunger made comparatively lonv in practice and having a pistonrod 21 with a thumb-button 22 which can be depressed to 4impel the plunger 20 inward.

23 denotes a cap screwed upon a threaded extremity 24 of the base 2 and adapted to inelose packing material 25,if desired, thereby constituting a gland for the piston rod. 'lhe plunger 20`is normally imp elled to its outer position shown in Fig. 1 by a spring 26 contained within the bore of the pump chamber. .At its inner end the pump bore is narrowed to forni a chamber 27 for the valve `28. I make the valve 28 similar to the valve 11, already described, in the form of a cupshaped, sheet metal part impelled by a spring 29 having a reduced extremity 30 which enters the.v cavity of the cup.

31 designates a perforated disk or washer constituting the valve seat' for the valve 28, being fixed within the pump bore or recess at a suitable point for this purpose.v This plate or washer is also adapted to constitute an abutment for the spring 2G. 32 designates a dischar e spout or nozzle having a passage 33 whic communicates with the interior chamber'27 of the pump.

In use the receptacle l is lled with the soapy liquid or compound through the opening 16, as already described. When it is desired to obtain a quantity of the soapy compound, the button 22 is depressed, fre ing the plunger 20 inward and compress ing the liquid in the space 26 past the valve 28 and outward through the discharge nozzle 32. In this action the opening 19 1s closed by the plunger itself as soon as the latter has moved through a sli ht range of its movement, so that thereailcr the ejection of the soapy compound is accomplished with absolute positiveness. When the plunger 20 starts to return, a partial vacuum is created i in the pump bore or chamber on account of the immediate closure of the valve 28 by its impelling spring. Into this vacuum the soapy compound is quickly forced by atmosplierie pressure through the opening 19 as soon as the latter is uncovered by the movement of the plunger. The pum chamber is thereby immediately filled wit a new supply of soapy .com ound Without de ending on gravity or ot er factor of suc certain character or ma nitude.

In Fig. 3 I have il ustrated a slightl modified construction of inlet valve in whic thenut or collar 8 is dispensed with. -In this case the cap 14 screws directly upon the upper threaded end of the cage 6 and constitutes the retaining means therefor in addition to its function as a valve seat. In other respects theconstruction of Fig. 3 is between said similar to that @#Fi 2 and need not there fore be more pa'ti'cu arly described.

1. In a soap dispenser, a receptacle, a base for said receptacle'having a pump bore and also a port leading from said receptacle to said bore, a plunger in said bore, means for normally forcing said plunger to its outermost position, a perforated disk having the perforation therein in substantial alinement with the axis of said plunger, a check valve normally closing said perforation, said base having a recess therein in which said valve is disposed, and a downwardly projecting nozzle opening'into said recess, said longer being movable toward said disk and the arrangement of the above recited parts being such that the initial movement of the plunger closes the port from said receptacle, the fluid in said bore being positively ejected by the continued advance of said plunger through said disk and out of said nozzle, in close proximity to the hand of the operator, the axial position of the check valve preventing. frumming up of the same by the eiected Hind.

3. In a soap dispenser, a. receptacle, a base therefor having a pump bore and hav.- ing a passarve establishing communication bore and said receptacle, a plunger movable in said bore and having an initial position just uncoverincr said assage, said plunger having a predetermined stroke and a length greater than such stroke, whereby it constitutes a piston valve to close said passage, a discharge nozzle for said bore, a perforated disk at the inner end of said here, a, cup-shaped sheet metal part normally closing the perforation of said disk, and a spring maintaining said part in such relation, said spring having a reduced portion entering said part to center the latter.
