JOHN MOHN AND CHARLES W. LARM OF DETROIT, MICHIGAN.

COMBINED TAP AND PUMP.

SPECIFICATION forming part of Letters Patent No. 674,510, dated May 21, 1901.

Application filed July 16, 1900.

T0 at whom, it ntay concern:

Be it known that we, JOHN MOHN and CHARLES W. LARM, citizens of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in a elevation showing the same as applied to a bottle. Fig. 3 is a perspective view of the main valve-casing and the key for operating the valve, and Fig. 4 is a detached sectional view of a modified form of cap.

In the drawings thus briefly referred to the reference-letter A designates a closure device in the form of a valve-casing which terminates at one end in a plug or elongated threaded nipple B and at the opposite end in a circular head C. 1

D and E are ports formed within the casing and extending through the head and nipple, as shown. The port D constitutes a passage for the discharge of the fluid from the receptacle, and the port E an inlet for the air which is forced within the receptacle by the pump F, hereinafter described. These ports are controlled, preferably, by a single plug-valve G, which is provided with a triangular stem H, that projects beyond one side of the valvecasing and is protected "by a lock-shield I, as shown in Fig. 3. The valve is adapted to be operated by a key or wrench J, and K is alug on the key, which extends within the recess L in the shield and limits the movement of the key in both directions. Upon the extreme end of the threaded nipple described is screwed a stuffing-box M, which is adapted to receive and hold one end of a tube 0, formed, preferably, of glass. The tube at its upper end registers with the port D in the casing and is of a length suflicient to extend inprox- Serial No. 23.774. (No models imity to the bottom of the bottle P, as indicated in Fig. 2.

Q represents a port formed within one side of the stuffing-box, leading to the air-inlet port E in the casing.

Threaded upon the stem above the stuffingbox described is a collar R, having the head S thereon provided with the oppositely-arranged recesses T, adapted to receive the Wrench. Upon the stem intermediate the collar and the stuffing-box is an expansible packing U, preferably formed of a series of rubber packing-rings V.

The reference-letter W designates a cap detachably secured upon the circular head 0 of the valve-casing, and X designates a packingring intermediate the cap and head, as shown in Fig. 1. The means for securing the cap to the casing consists, essentially, of an ear a in the form of a hook, which extends beneath the circular head, and a depending lugb, which carries a screw or bolt 0, adapted to engage beneath the head, as shown. The detachable cap thus described is provided with an extension A, which, in addition to forming a support for the pump F, constitutes the lower head of the latter. Upon this extension is an annular flange B, internally threaded, as at O. This flange forms a socket for the barrel D of the pump. E is a packing-ring preferably interposed between the pump-barrel and the extension. F is the usual pump-piston, and G is a handle secured to the stem H for operating the pump. A valve-chamber I is formed within the extension A immediately beneath the pump-barrel, and an annular flange J restricts the opening between this chamber and the barrel. Within the restricted opening is fitted an apertured block K, and L is a check-valve arranged within the chamber and secured to the block in any suitable manner. Communication between the pump and the air-inletE within the valvecasing is established by means of the air-conduit M, formed within the cap and its extenthrough the cap and packing X, with the liquid-discharge-portD. Thisdischarge-pipe is preferably in the form of a faucet of usual construction and is provided with a threaded portion Q, extending within and having a threaded engagement with the cap, as plainly shown in Fig. 1.

The tap having been thus described, the application of the same is as follows: The nipple or plugof the closure device, with the packing thereon, is inserted within the receptacle, which in this case is a bottle, as stated, and a tight joint is formed between the valve-casi ng and the bottleneck by turning the collarR in a direction to expand the packing. The cap carrying the' faucet and pump is secured to the casing-head C, and to insure a proper registration between the ports in the cap and the valve-casing the cap is held in proper position by means of spaced lugs 01. 0, upon the easing-head, between which the lug (it extends. During the operation of charging the receptacle the faucet is normally closed and the valve G opened. The air is forced into the receptacle by means of the pump through the air-inlet E and port Qand is prevented from escaping into the pump-barrel after the charging by the check-valve L. The filled receptacle is then in readiness for use, and the liquid is discharged in the usual manner from the receptacle upon the opening of the faucet.

It will be obvious from the construction of the tap that a single cap may be used for charging or discharging a large number of bottles or receptacles, as after the air has been forced Within the bottle the valve in each valve-casing may he turned to prevent the escape of the air and the cap then removed for the purpose of charging airinto or discharging liquid from another bottle.

While we have shown and described a particular type of pump mounted upon the extension of the cap, We do not desire to be limited to this particular formation, as various modifications could be made without departing from the spirit of our invention. For instance, a cap, could be employed such as is shown in Fig. 4, wherein the extension is entirely dispensed with. In this case an air-conduit M is arranged in close proximity to the faucet directly over and comm unicating with the air-inlet port in the casing. A pump of any type could be connected to the air-conduit, either directly or indirectly, as by means of a flexible coupling, such as M the free end of which fits over the nipple M, which forms the receiving end of the conduit. It is also to be understood that while we have shown our invention as applied to bottles it may be as readily used in connection with barrels, kegs, or any receptacle adapted to contain a fluid.

What We claim as our invention is- 1. In a combined tap and pump, the combination with a valve-casing having an airinlet and a liquid-discharge portformed therein, a nipple at one end of the casing through which the ports extend, a valve controlling said ports, a cap detachably secured to the opposite casing end, a valve-controlled discharge-pipe upon the cap communicating with the liquid-discharge port in the casing,an airconduit extending through the cap and leading to the air-inlet port, and a pump connected to said air-conduit.

2. In a combined tap and pump, the combination with a valve-casing having an airinlet and a liquid'discharge port extending therethrough, means within the casing for controlling said ports, a detachable cap for the casing, a valve-controlled discharge-pipe and a pump arranged upon and secured to the cap, and conduits leading from said discharge-pipe and pump to the valve-casing ports. V

3. In a combined tap and pump, the com* bination with a valve-casing having anair inlet port and a liquid-discharge port formed therein, a nipple at one end of the casing through which said ports extend, a single valve controlling the two casing-ports, a cap detachably secured to the casing, a valvecontrolled discharge-pipe and a pump mount ed upon the cap, and conduits leading from said discharge-pipe and pump to the ports within the casing.

4. In a combined tap-and pump, thecombination with a closure device, valve -con trolled air and fluid passages therein, and a pump detachably connected to the closure device, having a'port connecting with the airpassage in said closure device.

5. In a combined tap and pump, the combination with a valve-casing having a liquiddischarge port and an air-inlet port formed therein, a threaded nipple .at one end of the casing through which said ports extend, a stuffing-box upon the'nipple end, a tube extending within the stuiiing-box and communicating with the discharge-port within the casing, a collar threaded upon the nipple, an expansible packing intermediate the collar and the stuffing box, a cap detachably secured to the casing, a valve-controlled liquiddischarge pipe and a pump arranged upon and secured 'to the cap, conduits extending through said cap connecting the dischargepipe and pump with the ports within the easing, and a single valve controlling the casingports, substantially as'describe 6. In a combined tap and pump, the combination with the closure device, of valvecontrolledair and fluid passages extending 'therethrough, and a connected pump and tap detachably secured to the closure device, the pump having a port connected with the airpassage in said closure device.

In testimony whereof we affix our signatures in presence of two witnesses.
