Nov. 1, 1932. H. R. BOYER CARBONATING VESSEL Filed Feb. 15, 1932 ATTO RNEYaS' Patented Nov. 1, 1932 PATENT OFFICE HAROLD It. BOYTJR, OF GROSSE POINTE FARMS, MICHIGAN CARBON .ATIN G VESSEL Application filed February 15, 1932. Serial No. 593,164.

The invention relates to apparatus for carbonating liquids and it is the object of the invention to obtain a simple and inexpensive construction of portable apparatus which can be used for this purpose.v To this end the invention consists in the construction as hereinafter set forth.

In the drawing:

Figure 1 is a vertical central section through the carbonating vessel;

Figure 2 is a horizontal section on line 2-2 of Figure 1;

Figure 3 is a top plan view.

The tank or vessel is formed of a pair of pressed sheet metal cups A and B having their peripheral edges welded together at C. The lower cup B has an indrawn central portion B and the upper cup A is fashioned to form an upwardly extending neck portion D with a radially inwardly extending flange E surrounding the central opening. The neck portion D is slightly return bent so as to form an outwardly extending bulge or bead D with a contracted portion 1) between the same and the top wall of the cup.

F is a split band for surrounding the neck D and which is of a concavo-convex section so as to fit over the bead D. On opposite sides of the split the band F is provided with lugs F which are secured together by a clamping screw G, thereby holding the band firmly clamped to the neck. H is a cover plate having a downwardly extending flan e H for fitting within the annular flange and for receiving thereabout a sealing gasket I. The cover plate H has a plurality of lugs H at distributed points around its periphery apertured for the passage of a clamping screw which clears the bead D and engages threaded apertures in lugs F on the band F. Thumb screws J engage these lugs to clamp the cover upon the tank and to form a hermetic seal.

The cover plate H has formed integral therewith a discharge fitting K to which is connected a tap Leontrolled by a valve M. A pressure gauge N is mounted on the cap H to communicate with the space within the tank and a pop safety plug 0 .in, the gas injection valve stem P is also mounted on this cap. A tube Q connected to the fitting K depends obliquely therefrom and is of suflicient length to extend down into the annular portion of the bottom of the tank surrounding the indrawn portion B.

With the construction as described, the liquid to be carbonated is first filled into the tank after which the cover is placed in position and clamped down to form a hermetic seal. The carbonating gas may then be injected through the valve stem P, the pressure being indicated upon the gauge N. The tank may then be rolled or agitated in any way to facilitate the absorption of the gas by the liquid. Then the process is completed the carbonated liquid may be drawn oil by opening the tap valve M, the gas pressure serving to discharge-the liquid through the pipe Q.

The manufacturing cost of this a paratus is comparatively low, as the cups X and B may be formed of pressed sheet steel and after welding these sections to each other, the whole tank may be enameled both outside and inside. The other elements of the structure are cheaply manufactured and easily applied.

What I claim as my invention is:

1. An apparatus for carbonating liquids comprising a tank formed of two pressed metal cups having their edges welded together, the upper cup being provided with a neck portion having an annular bead pressed therein and also provided with a radially inwardly extending flange at its upper end, a grooved split band or collar clamped about said bead, a cap, clamping bolts for securing said cap upon said flange, said bolts engag ing threaded apertures in said band or collar, a discharge fitting integral with said cap and projecting laterally therefrom, a tube connected to said fitting and projecting downward to the bottom of said tank, a valve stem connected with said cap for the introduction of gas into the tank and a valve controlled tap connecting to said fitting.

2. An apparatus for carbonating liquids comprising a tank formed of a pair of pressed sheet metal cups having their edges Welded together, the bottom cup being centrally pressed inward to form an annular trough around its outer edge, the other cup being provided with'a neck portion with an annular cad pressed therein and a radially inwardly extending flange at its upper end, a split'band or collar grooved to fit about said bead and clamped upon said neck, said band being provided with a handle portion projecting therefrom, a cap provided with a discharge fitting and a tube extending downward from said fitting and inclined to engage its lower end in the annular trough surrounding the inwardly pressed central portion of the tank, bolts for securing said cap upon said flange, said bolts engaging threaded apertures in said split band or collar, a valve stem connected to said cap for introducing gas into the tank, a valve controlled tap connecting tosaid discharge fitting and a safety pop valve also connected to said cap.

3. An apparatus for carbonating liquids comprising a tank provided with a neck portion with a surrounding bead thereon, a cap for closing the tank and a split band or collar grooved to fit about said bead and clamped u on said neck, said band being provided with'a handle portion projecting therefrom and lu s distributed thereabout having threade apertures therein and clampin screws for said cap engaging said threade apertures.

In testimony whereof I aifix my signature.

HAROLD R. lEOYER.
