CARBONATING AND DISPENSING REGEPTACLE FOR LIQUIDS Filed March 13, 1957 HUN INVENTOR. a/PL F Lozo/v ATTORNE 5 7 Patented l0, 1939 UNITED STATES CARBONATING AND DISPENSING RECITTACIE FOR LIQUIDS cm F. Lozon, Mauillon, Ohio Application March 13, 1937, Serial No. 130,733
3Clalms.
Heretofore it has been customary to make devices of this kind from glass and to reduce the danger from explosion by making the glass very thick and heavy and enclosing it in a metal sheath, the primary purpose in using the glass being to avoid tainting the contents by reaction with a metal which might otherwise be used instead of the glass. I have found that the liquids that are carbonated and dispensed from a device of this kind are not affected by contact with stainless steel and it is, therefore, one of the objects of my invention to provide a device that is so constructed as to be capable of being manufactured from stainless steel and thus-be com-' paratively light and convenient to handle and yet have the requisite strength to safely withstand any pressure to which it may be subjected in use. I
A further object of the invention is to provide a device of the kind referred to with an improved form of dispensing valve that is mounted on the exterior of the cover and not only practically leak-proof, but adapted for convenient operation.
A further object of the invention is to provide a device of the kind referred to that will be simple in construction, efficient in operation, and adapted for economical manufacture on a massproduction basis.
Other objects of the invention and the features of novelty will be apparent from the following description, taken in connection with the accompanying drawing, of which Fig. 1 is a composite view, partially in side elevation and partially in central longitudinal section, of a device embodying my invention;
Fig. 2 is a detail section on the line 22 of Fig. 1;
Fig. 3 is a detail section on the line 3-3 of Fig. l; and
Fig. 4 is an enlarged detail section on the line t--t of Fig. l.
Referring to the drawing, ill indicates the body of the receptacle, which is substantially cylindrical in form and provided with a concave domeshaped bottom ii and a slightly inturneol top flange i2. As will be noted from Fig. l, the opening i3 into the body ill is only slightly less than the diameter of the body so that the interior of the body is readily accessible for cleaning, when the cover It is removed. The large top opening also permits ordinary-size ice cubes to be readily put into the body l0 when desired. Adjacent its upper end the body I0 is provided with a circumferential series of lugs i5 having a substantially straight lower edge l6, these lugs being formed by pressing the metal outwardly without rupturing it; Any desired number of the lugs I5 may be provided but, in practice, I prefer to employ seven of these lugs equally spaced circumrereiitially.
The cover I! is a substantially dome-shaped structure with a flat top I! and an enlarged lower part l8 which forms a skirt that is adapted to telescope over the exterior of the body in. The enlargement of the skirt portion of the cover also provides an internal shoulder or seat l9 against which a rubber gasket 20 is adapted to be positioned. As will be seen from Fig. 1, the lower edge of the gasket 28 is thickened so as to fit between the flange i2 and the skirt is and thereby seal the joint at this point, the internal pressure forcing the gasket into tight engagement with all of the metal parts with which it contacts, and the gasket thus serves as a means for efiectively locking the cover it to the body it so that the cover cannot beaccidentally or otherwise rotated relative to the body so long as there is pressure within the device.
There is a central opening in the top I! and a tubular bulb-receptacle 2! extends through this opening as shown. The bulb-receptacle 2! has a flange 22 at its upper end which rests upon the top ii and is secured thereto by welding or in any other suitable manner. The upper end of the flange 22 is provided with a radially extending lip 23 and this lip is spaced a short distance above the top H. The body of the receptacle 2i is provided with two oppositely arranged longitudinal grooves 26 on its exterior, these grooves forming ribs 25 on the interior of the receptacle 2i.
A cap 26 is arranged over the receptacle 2| and has its lower end arranged to engage the surface IT. The lower edge portion of the cap 26 has a plurality of internally projecting lug-like parts 21 formed therein by making shear cuts, parallel with the lower edge, and then pressing the metal between these cuts and the lower edge inwardly as will be seen from Figs. 1 and 3. There are preferably four equally spaced lug-like parts 21 and the lip 23 is provided with a similar number of equally spaced notches 28 which permit the cap 26 to be telescoped over the flange 22 and then, by rotating the cap 26, the parts .21 are positioned under the lip 23, as shown in Fig. 3. A downward depression 29 in the lip 23 is adapted iii) to be engaged by one of the parts 21 and act as a stop to limit the rotation of the cap 26 so that when one of the parts 21 is in engagement with the depression 29 the cap will be locked in position under the lip 23.
An internally threaded sleeve 30 is arranged in a. central opening in the top of the cap 26 and is provided with a flange 3| which engages the exterior of the cap. The sleeve 30 is secured in position, after it is inserted in the opening in the cap 26, by turning over a flange 32 on the interior of the cap, as will be seen from Fig. 1. This may be done by means of a shaving tool which is forced over the inner end of the sleeve 30 and shaves down the metal to form the flange 32.
At the bottom of the receptacle 2i there is a piercing device which consists of a tubular member 33 having a flange 34 that engages the bottom of the receptacle 2|, and an externally threaded part 35 which receives the nut 36 whereby the bottom of the receptacle 2! is clamped between the nut and the flange 34. The upper end of the piercing device is beveled, as shown at 31, to provide an eflicient cutting edge that is adapted to pierce the bottom wall 36 of a bulb 39, arranged in the receptacle 2|. There is a rubber gasket 40 at the bottom of the receptacle 2i and surrounding the piercing device, this gasket engaging the exterior of the bottom 38 of the bulb and forming a seal which prevents the escape of the compressed gas, along the exterior of the bulb, when the latter is pierced, as will be hereinafter described.
A screw 4! is arranged in the sleeve 30 and provided with a suitable handle 42 at itsupper end. The lower end of the screw 4| is adapted to engage the upper end of the bulb 39 so that, by turning the screw, the bulb will be forced downwardly against the piercing device and cause the latter to puncture the bottom wall of the bulb and thus allow the gas to escape from the bulb through the piercing device and into the interior of the carbonatingreceptacle.
When the screw 4i is out of engagement with the bulb 39, the cap 26 may be rotated and removed, thereby making the bulb accessible for removal, and permitting the insertion of another bulb. The cap 26 is then replaced and rotated to its locked position, and this permits the charging operation to be repeated.
The skirt portion l8, of the cover i4, is provided with a circumferential series of bayonet slots which cooperate with the lugs i5. These slots are formed by pressing the metal of the skirt outwardly as shown at 43, the metal being out along a line 44 and thereby forming an edge which is adapted to engage with the lower edge I6 of the lug l5. These bayonet slots are sub stantially hook-shaped and are widened at the lower edge of the skirt l8 so as to facilitate registration of the slots with the lugs l5. The gasket i9 is carried by the cover l4 and, in placing the cover in position on the body l0 it is telescoped over the lugs l5 and then rotated to effect the engagement of the edges 44 with the lower edges I6 of the lugs. From Fig. 1 it will be noted that the edge 44 is slightly inclined downwardly away from the vertical portion of the slot 43 and this, with the locking effect of the gasket 20, insures against accidental rotation of the cover, relative to the body l0, when the receptacle has a substantial pressure therein.
There is a flattened area 45 on one side of the cover l4 and a central opening in this area. Ar-
ranged in this opening is a tubular member 46 which has an external flange 41 that engages the area 46, and an internal flange 48 that cooperates with the flange 41 to secure the member 46 in position, the flange 48 being preferably formed in the same manner as the flange 32 of the sleeve 30. A short piece of rubber tubing 49 is telescoped over the member 46 and carries a tube 50 which extends to a point adjacent the bottom of the body Ill. The tube 50 is preferably made of stainless steel or a tough, substan tially unbreakable material which is neutral to any liquid that the receptacle is intended to receive and, for this purpose, I prefer to use a tube made of a composition known as tenlte. By having the tube 50 carried by the rubber tube 49 it is free to move and cannot be damaged by ice cubes when the device is used as a shaker.
The outer surface of the flange 41. serves as a seat for a valve 5| which is preferably made of rubber and mounted in av housing 52 having a stem 53 secured thereto. A valve body 54, preferably in the form of a cup-shaped cylindrical stamping, is secured on the flat area 45 by having its flange 55 welded thereto. The stem 53 projects through the end wall of the body 54 and a gasket 56 is arranged on the interior of this end wall so as to prevent leakage along the stem. There is a washer 51 on the gasket 56 and a spring 58 engages this washer and also the housing 52, normally exerting sufficient force on the latter to hold the valve 5i against its seat, in opposition to the pressure within the receptacle. A trigger 59, in the form of a channel-shaped stamping, is connected with the valve stem 53 by a pivot pin 60 and the portion iii of this trigger is arranged to fulcrum on the end wall of the valve body 54 so that when the trigger is depressed the valve 5| will be lifted oif its seat and permit the contents of the receptacle to be discharged through the tube 50 and into the interior of the valve body. There is an opening 62 in one side of the valve body, and a nozzle 63 is pressed over the valve body 54 and has a discharge opening 64 which registers with the opening 62 so that the contents of the receptacle may be discharged through this nozzle.
For the purpose of safety various parts of the apparatus are so relatively proportioned that it will be impossible to so charge the receptacle as to have an excessive or dangerous pressure therein. The body ID, in one commercial form of the apparatus, has a capacity of approximately sixty cubic inches of liquid when fllled to the maximum. Under these conditions and with the cover M in position the free space within the cover is approximately eighteen and one-half cubic inches. The bulbs for which this apparatus is designed have a charge of from one hundred twenty-five to one hundred thirty grains under a pressure of about nine hundred pounds per square inch. Under these conditions, when the charge in the capsule is released into the receptacle the maximum pressure will not exceed one hundred fifty pounds per square inch and, when the receptacle is used for charging water with CO2 gas, the absorption of the gas, by the water, will rapidly reduce the pressure to about fifty pounds per square inch, and this pressure will be sufiicient to discharge all of the liquid through the nozzle 63.
The conditions just referred to are those in which the maximum pressure can be produced within the receptacle by the capsule charge and, of course, if the body I0 is only partially filled arcane the gas, above the water. Since the parts have been designed so as to permit the body lllto be completely filled with water and, nevertheless, prevent a dangerous pressure within the receptacle, the construction and arrangement of the parts of the receptacle constitute an important safety feature.
All of the metal parts of the apparatus are preferably made of stainless steel and thus not only have the requisite strength but are non-corrosive and avoid tainting of the liquids but permit the apparatus to be maintained at all times in a thoroughly sanitary condition.
Having thus described my invention, I claim:
