UNITED STATES PATENT rEicE.

LIQUID-DISPENSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 551,541, dated. December 17, 1895. Application led June 8, 1895. Serial No. 552,062. (No modeL` To @ZZ whom it iai/ay concern.-

Be it known that I, WILLIAM MILES Fow- LER, of Stamford, in the county of Fairfield and Sta-te of Connecticut, have invented a new and useful Improvement in Liquid-Dispensing Apparatus, of which the following is a specification.

My invention relates to an improvement in liquid-dispensing apparatus in which provision is made for completely sealing the liquid within a reservoir from which it is to be drawn during the gradual lowering of the liquid within the receptacle, and to. further provide for the refilling of the receptacle or reservoir Without introducing air therein.

In the accompanying drawings, Figure l is a view of the apparatus in front elevation, and Fig. 2 is a vertical longitudinal section from front to rear.

The reservoir itself, here shown of cylindrical form and constructed of glass, is denoted by A. It is provided with a domeshaped cover a, which is tightly seated on the top of the reservoir A and held in position by a rim a', Which at the same time forms an ornamental iinish around the top oi the reservoir. The reservoir stands upon a hollow supporting-base B, which is preferably made somewhat larger than the reservoir itself and of any attractive conformation in outline, as may be desired. I have shown, in the present instance, the rim d' connected with the base by pillars a2.

The bottom of the reservoir is denoted by a3 and is made dish-shaped. The bottom 0.3 is

^ provided with a short nipple C, which projects upwardly above the bottom a3 into the interior of the reservoir a sufficient distance to guard against drawing the settlings of the liquid in the tank and is provided in its upper end with a tapered valve-seat c. Below the bottom d3 there is located a receiver l), the interior of which is in communication through the nipple C with the interior of the reservoir A. From 'the receiver D a discharge-pipe E curves upwardly to the edge of the base l5 and connects there with a dischargepipe e., in which is located a stop-cock F. rllie stop-cock F is provided with a port 5o f through it, so that when turned in one die. The cock F is further provided, intermediate of the ends of the port f, with a shallow channel f which, when the cool; F is turned in a direction to cut off the discharge through the pipe e, Will come in communication with a small opening e' through the Wall of the socket in which the cool; F is seated. At this same time the channel f Will be in communication with the discharge end vof the pipe e.

The top a of the reservoir is provided with a tubular vent G, in which there is a valveseat g. A valve g' has its stem fixed to a vertically-sliding cap g2, which made to fit over the upwardly-projecting portion of the tube G, and a spring g, interposed between the under side oi the cap gA2 and the top of the seat C, serves to hold the valve g' normally seated. Openings gY1 through the bottom of the seat g communicate with openings g5 in the side of the cap g2 to permit air to enter the reservoir A above the seal therein as the liquid is lowered, provided the cap g2 be depressed to throwthe valve g oil? its seat.

The seal relied upon to completely shield the liquid Within the reservoir A is a liquid of such a nature that it will not mingle With the liquid to be dispensed and may be, i'or example, what is known in the market as Eclipse Vhite oil.7 Instead, however, of covering the entire surface oi the liquid Within the reservoir A with the liquid seal I iind it desirable to locate therein a float Il, which is of such dimensions as to freely slide up and down Within the reservoir A, the liquid seal being used'to ll the intervening space between the periphery of the float ll and the interior Wall of the reservoir A. The iioat is preferably made with the convex top 7i and with a tapered bottom 71., terminating at its apex in a downwardly-extending nozzle 71,2, which may be iilled with lead or some suitable weight to make the lioat Il at all times retain the proper position within the reservoir. The loiver end of the nozzle h2 is fitted with a tapered nose h3, which is adapted to fit tightly' within the upper portion of the nipple C, forming in elifect a cut-olf valve when the float has reached its lowermost limit.

To hold the iioa-t II at its lowermost limit and tightly seal the communicaiion between the receiver Dand the interior of the reser voir, I provide a screur I, which extends up IOC through the bottom of the receiver I) and within the nipple C, where it engages a screwthreaded socket 7L* in the end of the nose h3. By this means I am enabled to screw the .float H down tightly and force the nose 7b3 snugly into cont-act with the walls of its seat. The float H is also provided with a tapered projection h5 at its top, which serves to enter the mouth of the tube G in the cover when the fioat is at the upper limit of its movement and thereby form a tight closure at the top to prevent the further filling of the reservoir.

The liquid which is to form the seal may be, for purposes of shipment, confined tightly within the receiver I) beneath the bot-tom of the reservoir by turning the screw I into the nose or valve h3, drawing it snugly down into the seat C, and turning the stop-cock F, so as to close the discharge from the pipe E.

Then it is desired to fill the reservoir A with claret wine or other liquid to be preserved, the hose for transmitting the wine or other liquid from the cash to the reservoir A maybe connected with the discharge-pipe c, and the force-pump bein set in operation the liquid may be forced up to the stop-cock F, the air in the meantime escaping through the channel f and perforation e.

lVhen liquid appears at the perforation c', the stop-cock F may be turned a qu arter-turn to bring the port f into communication with the pipe c and receiver D up into the reservoir beneath the float H, the latter having been released by the turning of the screw I, so as to permit it to rise from the inflowing liquid. The sealing liquid-oil, for example-being of lesser specific gravity than the liquid which is to be sealed will rise on the top of the infiowing liquid and gather around the periphery of the float H between it and the interior wall of the reservoir A, forming an air-tight closure, together with the fioat H, over the entire surface of the liquid. During this operation the valve g will have been held depressed to permit the air to escape from above the inflowing liquid within the reservoir A.

sealing liquid reaches it.

As the float II reaches the top of the reservoir A, the projection h5 on its top will enter the mouth of the tube G and engage with the valve g, forcing it to its seat and thereby preventing` any further escape of air at the top of the reservoir and consequently will shut oii' the escape of the sealing liquid through the vent at the top of the reservoir, as the valve g will be forced to its seat before the Furthermore, the projection h5 is of such size and shape that its base will form an air-tight closure with the lower end of.' the tube G and shut o'ft the further escape of air independently of `the valve g/ at the saine moment that the valve g is forced to its seat, so that if the valve g were dispensed with there would still be an auto- 6 5 matic closure at the top of the tank before the sealing liquid would escape. Again, in drawing the liquid from the reservoir A, the nose or valve 7b3 will seat and shut off the further discharge of the liquid before the liquid has reached a point where its dregs would be drawn, so that the sealing liquid is still held in position ready for the refilling` of the reservoir A.

l. The combination with a reservoir and an air vent at the top of the reservoir and a discharge device at the bottom of the reservoir, of a ioat free to move up and down within the reservoir, the said float being provided with an airvent closing device at'its top and a discharge closing device at its bottom for automatically limiting the inflow and outflow of the liquid into and from the reservoir, substantially as set forth.

2. The combination with the reservoir, a receiver at the bottom ofr the reservoir and means for introducing liquid into and drawing it from the reservoir, of a 'float within the reservoir provided with a device for closing communication between the reservoir and the receiver, substantially as set forth.

3. The combination with a reservoir, a receiver at the bottom of the reservoir and means for introducing liquid into and drawing from the reservoir, of a float adapted to close communication between the reservoir and the receiver and a screw engaged with the float for holding it snugly to its seat to close said communication, substantially as set forth.

4. The combination with a reservoir, a receiver in communication with the bottom of the reservoir and a filling and discharge conduit in communication with the receiver, of'

a float located within the reservoir and provided with a device for closing communication between the reservoir and the receiver7 substantially as set forth.

5. The combination with the reservoir and means for drawing liquid therefrom at pleasure, of a spring actuated valve at the top of the reservoir and a float within the reservoir provided with means for closing the spring actuated valve and the discharge, substantially as set forth.

(5.V The combination with a reservoir and a float within the reservoir, of a liquid seal wholly exterior to the float within the reservoir and free to distribute itself between the float and the wall of the reservoir when liquid is introduced within the reservoir, substantially as set forth.
