WILLIAM M. BYER, OF JERSEY CITY, NEW JERSEY.

LIQUID-DISPENSING DEVICE.

To all whom it may concern:

Be it known that I, WILLIAM M. BYER, a citizen of the United States of America, and a resident of Jersey City, New Jersey, have invented certain new and useful Improvements in Liquid Dispensing Devices, the principles of which are set forth in the following specification and accompanying drawings, which disclose the form of the invention which I now consider to be the best of the various forms in which the principles of the invention may be embodied.

This invention relates to liquid-feeding devices, as for the purpose of dispensing liquid soap for toilet purposes.

The object is a device possessing the improvements hereinafter specified, which shall be economical and convenient in operation, cheap in construction, easy of assemblage, compact in form and regular and efficient in its action of feeding predetermined quantities of liquid.

Of the drawings, Figure l is a vertical central section, and Fig. 2 a front elevation.

As shown in Fig. 1, the glass reservoir A for the liquid to be dispensed has a metal casing B and contains a piston-cylinder G with contained piston G, the cylinder or chamber C having a slot D substantially through its length from a point just below the upper limit of the play of the piston, for the purpose of utilizing the cylinder-interior above the piston asadditional available reservoir-space for the liquid. When depression of piston G, as shown, causes an out-flow of liquid from cylinder C, the liquid passes through a. pipe I constituting an intermediate riser-passage, to a gravity feed and splash eliminator to be described. If the liquid were forced exterior to the entire apparatus directly by the piston pressure, it would be emitted with such force as to splash or spatter against the hand of the person held in position below the bottom outlet Q to receive it, in a wasteful as well as an annoying manner. But here, not only is the riser-passage I always filled with liquid by the automatic operation of a check-valve J, such as the common conical construction, but also, it is forced out of passage I into a gravity outlet K constructed with an en largement or hopper K with which passage I communicates, which serves to take up the splash and eliminate its occurrence outside Specification of Letters Patent.

the apparatus, by acting momentarily as a reservoir which has a splash-eliminating function as to the final exit of the liquid. The liquid flows from K downward through K gently by gravity to and through the final outlet Q, and not under the piston-pressure, as Q and K furnish free upward access for air, and K may be open to the air in the upper part of the reservoir. This permits the hand of the user to receive the predetermined amount of liquid which fiows out in a gentle stream without spattering or splashing. If desired, the cylinder C may communicate directly with K, either in the illustrated location of the latter, (by reversing the direction of piston-action), or with the latter located below the lower end of C, with the direction of piston-action shown. The riser-passage I has, however, a most useful function in the illustrated construction and arrangement, and the latter in all its aspects, is the preferred embodiment of the invention. The pipe K may extend down so as to discharge directly into outlet Q. The relative construction of the parts, as well as their relative arrangement, is immaterial, provided that the described function is exeouted.

The advantage of retaining the function of the piston or its equivalent is to dispense a predetermined quantity of liquid. A cap F is provided as shown, having a downward projection F 4 fitting down into the top of the cylinder C and secured thereto. casing-top O may also be secured to the cylinderC. Reciprocable in cap F, F is a bushing F secured to the upper part of pistonrod E. A handle or push button P is secured to the upper end of piston-rod E. Bushing F has a lower flange-portion F fitting against the lower surface of cap-portion F this flange being engaged by the upper end of helical spring N. The lower end of the spring rests on a collar M which is secured, as by soldering, to the inside of cylinder G. Thus the spring normally acts upwardly against flange F 2 to hold piston G in position for operation, the cylinder below the piston being filled with liquid of a predetermined quantity dependent upon the location of the lower end of slot D. WVhen button P is depressed to compress the spring, the piston-rod and piston are also depressed to force the liquid into pipe I, opening The q check-valve J upwardly to force liquid throughout the length of said pipe. WVhen the hand pressure on button P is removed,

the liquid in the upper part of pipe I closes check-valve J downwardly, and the spring automatically raises piston G, the, liquid above G being free to be forced thereby through the entire submerged upper portion of the long slot D, to mingle with the liquid in the main reservoir outside of cylinder G, whence it reenters said cylinder but below the piston and through the lower part of slot D. This keeps pipe I filled with liquid up to the check-valve J, and, as the latter keeps the portion of the pipe I above it continually filled with liquid, irrespective of the liquidlevel in reservoir A, the next operation of piston G will force into K an amount of the liquid which stands in the upper part of pipe I which corresponds with the abovestated predetermined feed. Check-valve J may be operatively located approximately or substantially on a level with the lower face of piston G, so that by means of slot D, pipe I will be filled up to the check-valve as long as there is enough liquid in the main reservoir to reach the lower face of the piston. The cap F may be secured to metal cover 0, or as shown, C, to which F is secured, may be secured to 0, so that cylinder C and pipe I and their interior parts may be all removed at once, in case the pipe I is separable from K as shown.

The filling-inlet S in casing top 0 may contain at its lower part a float-valve U to prevent overflow in filling. If desired, the gravity outlet passage may be through a pipe K located in a space between A and B; but any suitable means may be employed. The top casing part 0, as well as the bottom casing part L, may be, screwed as shown, re-

movably attached to main part B; part L having an internal flange'L serving as a support for glass reservoir A. Main casingpart B is cut away in front, as shown in Fig. 2, to permit inspection of interior of glass reservoir A; or it may be complete if the reservoir is not transparent. The entire apparatus may be laterally supported from the wall, as by bracket-j aws R; or the standard T may carry the bracket R.
