-useful Improvements in Carbonated-Liquor Tanks, of which the following is a specification.

This invention' relates enerally to improvements in carbonated iquor tanks and particularly to means for Aprotectlngthe packing and preventing leakage about the shaft of the agitator, utilized in such tanks.

More specifically the invention relates to an agitator tank structure comprising a tank, having an agitator mounted in suitable bearings therein and adapted to be operated by suitable mechanismv extending throu h the tank and comprising-a stuiing'boxan bearing structure, an operating shaft extending therethrough, a head formed on said operat-v ing shaft and having ya driving and sliding engagement with the agitator shaft, together with means on the outsideof the stuffing box structure for operating the shaft and for moving it endwi'se to draw the head thereon against the stufling box and bearing struc-v ture to prevent leakage about this shaft.

The' invention may be further brieiy summarized as consisting in the combination and construction of parts hereinafter set forth in the following description, drawings and claims.

Referring to the drawings, Figure 1 is a vertical section through the tank, showing the valve mechanism and agitator; Fig. V2 is a horizontal section; Fig. 3` is a Section through the head looking toward the tank; and Fig. 4 is a section through the tank.

In carrying out the mvention any desired tank may be employed so long as it -possesses the necessary characteristics, but I at the center thereof for a purpose to be described. lheV opposite end of the tank is rounded and receives a head connection 4 rigidly secured to the tank in any suitable manner. Secured to this head connection is a suitable head 5 having therein a Water inlet and discharge chamber 6, a gas inlet 7 and a gas discharge chamber 8 connected to the head, and communicating with the main Specication of Letters Patent.

inlet and discharge is a pipe'9 extending into the tank and to, a point near the bottom thereof, as shown in'Fig. 1.. Leading out from the periphery of the'head and communicatlng with this same ldischarge chamber 6 1s a dlscharge pipe 10. AConnected to the gas 1nlet chamber is a suitable gas decarbonic acid gas from any suitale source. This chamber also communicates withthe .interior of the tank by means of a pipe 12 projectlnginto vthe tank and'directed downward toward the opposite end. The gasv discharge chamberS is connected by al pipe 18 with the gas space in the tank, as shown in Fig. l, and by a suitable discharge pipe 14. These pipes leading from the tank may be led to various points for use as desired.

The head 5 is provided with a central stuiiing box and bearing portion comprisingy a bear-lng 15 having a seat 16 toward the inside of the tank. A suitable enlarged opening 17 in the stufing box and bearing portion forms a suitable space for packing 18. A suitable gland ring 19 enters this space and this gland ring is held in place by a gland nut 20. Extending through this stuifing box and through the bearing 15 is a shaft 21 having a head 23 thereon provided with a plug portion adaptedto engage in the seat 16, and a squared socket 24 forreceiving a squared end 25 of the agitator shaft 26 which is mounted in the bearing 3 at the opposite end of the tank. The outer end of the shaft 21 is threaded at 27 and receives a nut 28. The extreme outer end of the shaft is provided with a suitable handle 29 or other agitating means.

The arrangement of the parts is such that when the nut 28 is loose upon the shaft 21, the shaft may be rotated freely and the proper agitation take place, the stuffing box preventing any leakage during the operation. When the agitating operation is finished, then the nut 28 is drawn up tightly against the gland nut 20causing the shaft 21 to be drawn outward and the plug portion 23 to be drawn tightly against the seat 16 4positively preventing any leakage from the tank to the stuling box.

rlhis device is utilized in fire extinguishers Where it is desirable to maintain a pressure for a long period of time without any considerable loss. The arrangement however is adaptable to any construction wherein liquid I livery pipe 11 adapted to be vsup lied with llt or gas is to be held under pressure and .there is a movable member such as an agltator shaft entering the tank.

Having described my claim 0 1. In anfagitator tank construction, a tank, an agitator movable therein, a combined bearing and stuing box mounted in said tank, an operating member extendlng through said stuiing box and operatively connected with the agitator, a plug o n said operating member, and means on sald operating member and external to the tank for positively seating said plug to prevent leakage about the operating member.

2. In an agitator tank const ructlon, a tank, an agitator movable thereln, a com bined bearing and stuffing boxvmounted 1n said tank, an operating member extending through said stuiing box and operatively connected with the agitator, a plug on sald operating member, and a nut threaded onto Vthe operating member for posltively seating the plug against the bearing and stuiing box for preventing leakage about the agitator member.

3. In an agitator tank construction, a tank, an agitator mounted therein, a combined bearing and stuffing box structure mounted i-n said tank, an operating shaft extending through said bearing and stuliing box structure, a driving head integral wlth invention, I

said shaft and having a driving connection with the agitator, sald head having a portion adapted to seat against the bearing and stu'ling box structure, and means exterior to the tank for moving the operating shaft endwise to bring about the seating of the head thereon against the combined bearing and stuffing box structure.

4. In an agitator tank structure, a tank, an agitator shaft mounted in bearings in said tank and having a squared end portion, agitator blades mounted upon said shaft, a combined bearing and stuffing box mounted in said tank, an operating shaft extending through said combined bearing and stuffing box, a head upon said shaft having a squared opening for receiving loosely the squared end of the agitator shaft, said head having a portion adapted to seat against the combined bearing and stuing box, and a nut threaded on to said shaft and outside of the tank for moving the same endwise to seat the head thereon against the combined bearing and stuffing box and thereby prevent 'leakage about the operating shaft.

In testimony whereof I aiix my signature in presence of two witnesses as follows:
