LIQUID-RECEPTAGLE.

1,os2,ec1.

To all whom it may concern Be it known that 1, WILLIAM H. TUCKER, a citizen of the United States, residing at EoXbury, Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Liquid- Receptacles, of which the following is a specification.

This invention relates to useful improvements in liquid receptacles.

The object of the invention is to provide a receptacle having a siphon attached thereto by which liquid contained in said receptacle may be removed therefrom in large or small quantities as desired, without having to tip the receptacle.

The invention consists in the combination and arrangement of parts whereby the above object and certain other objects hereinafter appearing are attained, as set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings: Figure 1 is a sectional elevation of a device embodying my invention. Fig; 2 is a detail sectional view taken on the line 22 of Fig. 1. Fig. 3 is a detail section partly in elevation taken on the line 33 of Fig. 2.

Like numerals refer to like. parts throughout the several views of the drawings.

In the drawings, 5 is a receptacle, which although it may be constructed in any desired form, is preferably provided with an opening at the top and a cover 6 adapted to close said opening and with a handle 7 pivotally attached to said receptacle by which the same may be more readily moved from place to place.

, The receptacle 5 comprises a main reservoir 8 and a supply chamber 9 preferably cylindrical in shape and vertically arranged relatively to the main reservoir, said supply chamber and said main reservoir being connected by an opening 10 at the bottom of the dividing partition.

An inverted U-shaped siphon tube 11 is arranged in connection with the supply chamber 9 with the leg 12 thereof telescop ing said chamber. A valve seat 13 is formed adjacent to the extremity of the leg 12 and is adapted to be engaged by a valve 141 having yielding engagement therewith and being normally retained in said engagementby a spring 15 encircling the stem 16 of said valve, said stem having sliding engagement with a support 17 which is secured to said Specification of Letters Patent.

leg 12. By reciprocating the leg 12 of the siphon 11 longitudinally of the supply chamber 9 said valve is arranged to be opened or closed according to the direction of movement of said leg and as said valve is opened the liquid contained within the main reservoir 8 will be siphoned outwardly through the opening 10 and discharged at the free end 18 of said siphon tube.

In order that a reciprocatory movement may be imparted to the valve 14 to open the same during the telescopic movement of the leg 12 within the chamber 9 I preferably provide a pair of levers 19 pivoted at 20 to the support 17 which in turn is secured to the extremity of the leg 12 by means of a screw-threaded collar 21. A sleeve 22 is adapted to encircle the support 17 and is provided with slots 23 which receive the ends 24: of the levers 19. The support 17 constitutes a guide for the sleeve 22 and during the telescopic movement of the leg 12 downwardly within the chamber 9 the sleeve 22, which engages the bottom of said chamber, continues to remain static-nary while the support 21 is moved down wardly thereby and consequently the levers 19 by engaging the ends of the slots 23 will be rocked upon their pivots 20. The inner ends of said levers 19 are arranged within a transverse slot 25 in the stem 16 of the valve 14 and engage a pin 26 therein, consequently as said levers 19 are rocked, as hereinbefore stated, the stem 16 will be moved thereby and the valve 14 moved from the valve seat 13 to quite a considerable distance therefrom, owing to the increased leverage of the levers 19. It will be obvious that as said valve is opened the liquid encircling the valve stem and the means for operating said valve will be admitted into the tube 11, it being understood that the level of the liquid within the reservoir 8 is higher than the uppermost point in the interior of the tube 11.

The action of a siphon tube is so well known to those skilled in the art that a full description of the same is not thought to be necessary, suflice it to say that after said tube has been once filled and all of the air ejected therefrom, the closing of the valve 1 1 will retain liquid enough in said tube to completely fill the same and when the legs of the U-shaped tube are of a sufficient length in proportion to their diameter, said liquid will remain therein with the free end of the tube open, for an indefinite period. In the present embodiment of the invention it is desired that the diameter of the tube constituting said siphon should be quite large and as the leg of said siphon tube has been purposely shortened to permit receptacles to be placed upon the support on which the receptacle 5 is resting, beneath the end 18 the liquid contained within said tube would be permitted to flow therefrom in case said receptacle is set down suddenly so as to cause a jar. To prevent such an oc currence a screen, preferably consisting of wire gauze 27 of fine mesh, is placed against the end 18 of the siphon tube 11 and a screw-cap 28 having an opening 29 therethrough is placed upon the end of said tube, said screen also serving as a filter as well as a support for the liquid contained in said tube and retards the admission of air thereinto thereby maintaining the column of liquid.

As hereinbefore described, the leg 12 of the siphon tube 11 is adapted to be reciprocated within the supply chamber 9 and as said supply chamber terminates slightly below the high water mark within said main reservoir 8 I have provided a cap 30 having screw-threaded engagement with the upper end of said cylindrical tube, which constitutes a packing to prevent said liquid contained within said receptacle from overflowing the top of the supply chamber 9.

The collar 21 which is secured to the eX- tremity of the leg 12 and comprises the seat 13, and the support 17 for the levers 19, is slightly enlarged at 31 to fit the interior of the cylindrical tube 9 and also assists in preventing the overflow of the liquid from said supply chamber.

A handle 33 is provided on the siphon tube 11 by which said tube may be reciprocated to operate the valve 14. By reference to Fig. 1 it will be noticed that the valve 14 is located at a substantial distance from the bottom 34 of the receptacle, but slightly below the end 18 of the siphon tube 11, this position of said valve being necessary in order to provide room for the mechanism beneath said valve to operate the same when said siphon tube is reciprocated, This height of the valve prevents the drawing off of the entire amount of liquid contained within said receptacle, it being a well known fact that the liquid will cease flowing through a siphon when the level of the same within the receptacle from which the liquid is being withdrawn, reaches the level of the discharge end of said siphon. By extending the end of the leg 12, within the supply chamber 9, slightly below the end 18 of said siphon the liquid, as above stated, will cease flowing before it has arrived on a level with said end and there will consequently be a suficient quantity of liquid to support the column of liquid within said siphon when the valve 14 is opened, to prevent the same from running back into said main reservoir.

lVith a receptacle constructed after the pattern of that illustrated in the drawings, too much liquid would remain in the bottom thereof particularly when it is desired to heat but a small amount of the liquid at a time, therefore an air tight draun 35 has been secured adjacent to the bottom of said main reservoir 8, said drum being of a sufli cient depth to displace the greater portion of the liquid which would ordinarily be contained therein, the lower wall 36 of said drum being arranged a slight distance above the bottom 34 of the receptacle. Several passages 37 are provided around the periphery of said drum 35 and a passage 38 is also provided extending substantially through the center of said drum, all of said passages uniting the chamber 39 below said drum with the rest of the main reservoir 8 and as the liquid, which is contained within said chamber 39 is heated the same will circulate upwardly through the passages 37 and 3S and the cold liquid at the top will settle to the bottom beneath said drum.

The general operation of the device hereinbefore specifically described is as follows: The main reservoir 8 is filled with liquid to the height as indicated in Fig. 1, which is preferably slightly above the uppermost point upon the interior of the U-shaped siphon tube 11. The receptacle to be filled with liquid from the main reservoir 8 is placed beneath the end 18 of said siphon tube and by placing the hand against the handle 33 said tube will be depressed, whereupon the levers 19, carried by the support 17 which in turn is supported upon the end of the leg 12 of said siphon tube, will engage the ends of the slots 23 in the sleeve 22 and be rocked upon the pivots 20, engaging the pin 6 in the valve stem 16 causing said valve 14 to move away from its valve seat 13 and permitting the liquid from the main reservoir 8 to fill the tube 11 completely discharging the air therefrom. After suflicient liquid has been withdrawn from the receptacle 8 the hand is removed from the handle 32 and the spring 15 returns said tube to its normal position and the valve 14 in contact with its seat 13. As soon as the pressure is removed from the column of liquid within the tube 11 the same will cease to flow from the end 18 and said tube will remain filled with the liquid until the next draft from the main reservoir is desired. Should the liquid within said siphon tube for any reason become discharged from the same and the level of the liquid in the main reservoir be below the uppermost point thereof, it will be impossible to again start the flow of liquid from the tube 11 without first removing said tube from the supply chamber 9 inverting the same, opening the valve 14 and filling the tube with liquid, then closing the valve after which said tube may be inverted and replaced in its position. As will be seen in Fig. 1, the leg 12 of said siphon tube is, in addition to being slidably arranged within the chamber 9, also rotatably arranged therewithin and consequently when the device is not in use the free end 18 may be swung back against the side of the receptacle 5 thus taking up less room.

Having thus specifically described my in vention, what I claim and desire by Letters Patent to secure is:

1. A device of the class described having, in combination, a receptacle comprising a main reservoir, and a supply chamber havmg communication with said main reservoir adjacent to the bottom thereof, an inverted U-shaped tube, one of the legs of said tube adapted to telescope said supply chamber, a valve located adjacent to the extremity of the leg of said tube within said supply chamber adapted to be manipulated by the telescopic movements of said tube.
