LIQUID-DISPENSING DEVICE.
Specification of Letters Patent.
Patented Aug. '7, 1917.
Application filed February 9, 1915. Serial No. 7,095.
To all whom it may concern:
Be it known that I, W'ILLIAM C. MORRILL, a citizen of the United States, residing in the city of New York, borough of Manhattan, county and State of New York, have invented a certain new and useful Liquid- Dispensing Device, of which the following is a specification.
This invention is a liquid dispensing device, the same being adapted for use, more particularly, in connection with a container wherein liquid soap is stored free from contact with air in order to preclude deterioration and coagulation of the liquid material.
In my prior Patent No. 911,834, granted Feb. 9, 1909, there is disclosed a form v of soap machine embodying a container, usually of glass, and a delivery device positioned at the bottom portion of said container and operable by an upward movement of the hand, said delivery device acting, mainly, to forcibly eject a limited predetermined quantity of the liquid material directly into the palm of the hand. Said delivery device as disclosed in said patent embodies a chambered body within which operates a piston adapted to control the flow of the liquid material into the space below it and to forcibly eject said material, said piston being normally depressed by a spring and being provided with a depending stem, the latter serving as a means for operating the piston at will and as a cut-off or valve when the piston is raised.
The delivery device of the aforesaid patent is composed of machined metal parts which are, comparatively speaking, expensive of manufacture.
My present invention embodies a construction, certain parts of which are composed of stamped or spun metal, thereby.
securing economy of manufacture, one of said sheet metal parts being so connected to the glass container as to afford protection to the fragile material of said container, thus minimizing the breakage thereof and imparting a desired finish to the machine More specifically speaking, the present invention embodies a closure or head composed of sheet metal and provided at its perimeter with a flange and at its center with a depending tubularboss, combined with a piston having a stem depending through a dellvery opening provided centrally in said tubular boss, and a sleeve, the latter being separate from the closure and attached in a suitable way to said closure head so as to cooperate with the piston and the pressure spring for said piston. Said sleeve performs several important functions, 2'. 6. it is positioned for frictional contact with the piston, thus acting as a guide for said piston in the vertical travel thereof; it houses or incases the spring and retains said spring normally in contact with the piston; it is provided in the sides thereof with ports positioned in such relation to the travel of the piston as to insure the inflow of the liquid material into the space below the piston as the latter is lifted; it is flanged and perforated at the top to afford a seat for the spring and to produce a port through which the liquid material, displaced by the upward travel of the piston, is free to flow out of the sleeve, and it is positioned in contact with a gasket adapted to serve as a seat for the piston when the latter is depressed by the spring, so that the sleeve retains the gasket in a predetermined position and precludes movement of said gasket with the piston as the latter travels within the sleeve.
The flanged closure or head is attached in any preferred way directly to the container, the latter being composed usually of glass. Said container is, or may be, provided at the bottom with a neck portion against which the flanged closure is fitted in a manner to embrace said neck portion, thereby affording protection to the fragile material. The connection between the closure and the container may be of a permanent nature or of a separable nature; but should the parts be separably connected, it is preferred to provide the container neck with a groove or grooves and the flanged closure with a stud or studs so as to cooperate as a bayonet lock, in which case a tight joint is secured between the container and the closure by the inter- Figure 1 is a vertical section through theclosure and the liquid-delivery device, the container being omitted for the sake of clearness, and the piston being shown in its normal lowered position. 1
liquid outlet, and through said liquid outlet the liquid material is forcibly ejected by the action of a piston.
17 designates a sleeve, composed of sheet metal. The sleeve is preferably uniform in diameter, except that the top portion of the sleeve is provided with an inwardly extending flange 18 in which is formed an opening 19 adapted to serve as a vent through which liquid may flow freely on the upward travel of the piston, the liquid contained within the Fig. 2 is a vertical section, similar to F-igfsleeve being displaced by the piston on said 1, withthe piston in a raised position so as to compress the spring, thereby placing thev piston in position for ejecting the liquid material on the downward movement.

Fig. 8 is a plan view on a reduced scale of the closure and the delivery device shown in Fig. 1.
Fig. 9 is a side elevation of the closure and the delivery device on the scale of Fig. 8.
A container for liquid material is indicated in Figs. 6 and 7 by the reference numeral 10,'said container being provided at its bottom portion with a contracted neck 11. It is apparent that the container may be of any desired shape and size and, further, that it may be composed of any appropriate material, such as glass.
12 designates a closure adapted to be applied to the neck 11 of the container for the purpose of tightly closing the opening in said neck of the container, thus precluding the leakage of the liquid material from said container. The closure 12 is'provided with a central depending boss 13 and with an upstanding flange 14, said boss and the flange being. integral with the closure. It is preferred to make the closure with the flange and the boss from a single piece of sheet metal which is punched, spun, or otherwise treated so as, to impart to the closure the form and dimensions illustrated in Figs. 1, 2, 8 and 9. The boss 13 is hollow or cham- ,bered and it depends centrally from the closure. The rim 14 extends upwardlyfrom the closure at the edge portion thereof, the
diameter of the rim exceeding the diameter of the tubular boss.
The tubular boss 13 is provided with an inwardly extending flange 15 at the lower end thereof and in said flange 15 is provided an opening, 16, the. latter constituting the upward travel. The lower part of sleeve 17 fits snugly within the chambered boss 13, said sleeve 17 being fixed to said boss 13 in a suitable way. It is apparent that the sleeve may be soldered to the boss or it may be attached by a screw-thread thereto, but the detailed connection of the sleeve to the boss may be varied as desired.
The sleeve is provided in one or both sides thereof with vertical slots 20, the latter serving as ports to admit liquid freely tothe space below the piston when the latter is in the raised position of Fig. 2, but when the piston is in the normal position, as in Fig. 1, said piston cuts off the flow of material into the'space below it, whereby the piston acts in a threefold capacity; first, as a means for controlling the flow of liquid material into the space below the piston, as well as to provide for the inflow of air to the inteice is provided with an integral depending stem 22, the latter passing loosely through the opening 16 which constitutes. the delivery port. Theexternal diameter of the solid piston head 21 is slightly less than the internal diameter Of the fixed sleeve 17, whereby the piston fits snugly within the sleeve and is free to move vertically therein. The external diameter of the rod 22 depending from the piston corresponds practically to the diameter of the liquid port 16, and when the piston and the rod occupy the raised positions of Fig. 2, said rod 22 practically closes the port 16, whereby the liquid ma terial admitted into the space below the piston is precluded from flowing out through the port 16. The rod 22 thus acts as a opening 16, at which time the liquid port is,
opened by a beveled or chamfered portion 23 prov'i ded on the surface of the stem 22, said, ehamfered portion 23 reducing the diaameter of the upper portion of the stem so that the stem when the piston is lowered does not close the port 16, but, on the contrary, the chamfered portion 23 provides a space between the surface of the stem and the edge of the liquid opening 16, through which space the liquid material is free to pass when said liquid material is acted upon by the piston on the downward travel thereof.
24 designates a gasket positioned within the tubular boss and resting upon the inturned flange 15 at the bottom of said boss. This gasket is composed of any suitable material and it forms a seat for the piston 21. The under side of the piston is provided with a rib or flange 25, preferably tapering or V-shaped in cross section, said rib or flange being embedded within the material of the gasket under the pressure of the spring 26 acting upon the piston. The ta pering flange cooperates with the gasket 2 1 in securing a liquid-tight joint at the bottom of the delivery device, and thus the piston acts in the capacity of a valve in cutting off the outflow of liquid and in precluding the leakage of liquid. In my prior patent the gasket is liable to become displaced by the movement of the piston stem through it, said gasket adhering to the piston stem and partaking of the movement thereof. In my present construction, however, this objection is overcome, for the reason that the gasket 24 is in contact with the lower edge of the fixed sleeve 17, said sleeve acting to retain. the gasket in a predetermined position and in contact with the flange 15 whereby the gasket cannot follow the movement of the piston stem.
The spring 26 is-housed or incased within the upper part of the fiXed sleeve, said spring being seated at its upper end against the inturned flange 18 of said sleeve, whereas the lower end of the spring is in contact with the piston for the purpose of forcibly depressing said piston, the pressure of the spring upon the piston being suflicient to force the tapering rib or flange 25 into firm engagement with the gasket 24.
It is apparent that the closure 12 is fitted to the neck 11 of the container in such manner that the flange 14 of the closure embraces the neck, thus imparting a desirable finish to the container and bringing the flanged closure in such relation to the container that the metal of the closure aflords protection to the fragile material of the container. The metal closure is adapted to be fastened permanently to the glass container by cementing the parts together, but when it is desired to separately attach the closure to the container I employ a series of studs 27 on the flanged closure and a series of grooves 28 in the neck of the container. The grooves 28 are inclined slightly and open at one end through the edge of the neck, as at 29. In connecting the closure to the neck the flange 14; is
tioned on-the upper face of the closure 12,
and within the flange 14: thereof, and by drawing the closure and the container together with a wedging action the gasket 30 is compressed between the edge of the container neck and the closure, thereby compressing the gasket and securing a tight joint which precludes leakage of the liquid material from the lower part of the container.
In the normal position of the parts the spring 26 acts upon the piston to depress it into contact with the gasket 24, the stem 22 depending a suitable distance below the tubular boss 13, thus exposing the stem 22 to convenient access, said piston 21 closing the lower end of the slots 20 in the fixed sleeve 17. To operate the piston. the hand is positioned, palm upward, below the stem 22, and by moving the hand upwardly the stem and the piston are raised to the position of Fig. 2, the spring 26 being under compression. Upon such upward movement of the piston the stem 22 slides through the open ing 16, whereby the stem acts to close said opening 16, and at this time the piston 22 is raised with respect to slots 20, whereby air is free to flow into the space below the piston so as to ultimately find its way into the interior of the container and at the same time the liquid material in the container is free to flow through the slots 20 and substantially fill the space within the fixed sleeve 17 below the piston. -VVith the parts in their raised positions, the liquid fills the space below the piston and the stem 22 closes the aperture 16, thus precluding the outflow of the liquid material and retaining said liquid material in the path of the piston. By removing the hand pressure from the piston stem, spring 26 acts to quickly depress the piston and the stem, the chamfered part 23 of the stem opening the liquid outlet 16, whereby the piston exerts pressure upon the liquid during the downward movement of said piston under the action of the spring, as a result of which a limited predetermined quantity of liquid is forcibly ejected into the palm of the hand, i. c. the latter is spattered upon the hand so as to become spread or diffused over it.
It is apparent from the description taken in connection with the drawings that the closure and the sleeve can be manufactured rapidly and economically from punched, stamped, pressed or spun sheet metal. Furthermore, the parts are simple in construction, easily and quickly assembled, and practical experience shows that the device is efiicient and reliable in operation.
Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent is:

In a liquid dispensing device, the combination with a container, and a closure pro-' vided with a liquid outlet, of a sleeve attached to said closure and extending up wardly within the container, said sleeve being provided with a slot forming aliquid inlet to the chamber of the sleeve, a valve seat within the closure engaged by the inner end of said sleeve, a .liquid controlling and ejecting piston provided with a depending stem, said piston having frictional contact with the sleeve and adapted to be raised relatively to the slot therein for permitting the flow of liquid into the space below the piston, and a spring for depressing the piston within the sleeve, said depending stem being slidable in the liquid outlet and the cross sectional dimensions of the stem for a part of its length conforming to the area of the liquid outlet'so that upon the elevation of the piston and the stem the latter closes the liquid outlet against the premature outflow of the liquid material.
9. In a liquid dispensing device, the combination with a container, and a closure provided with a liquid outlet, of a sleeve attached to said closure said sleeve being provided with a liquid inlet, a valve seat within the closure engaged by' the inner end of said sleeve a double valve member, one part of said valve memben operating within the sleeve to open the liquid inlet forthe liquid material to flow into the space within the sleeve below said valve member, and at the same time the other part of said valve member operating in the liquid outlet to close the latter against the outflow of the liquid material, and a spring cooperating with the double valve member so as to forcibly eject the liquid material upon the descent of the 15 double Valve member.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
