JOSEPH POSOH, OF ST. PAUL, MINNESOTA.

SPECIFICATION forming part of Letters Patent No. 780,682, dated January 24:, 1905. Application filed September 21, 1903. Serial IIo. 173,953.

To all whom it may concern.-

Be it known that I, JosnPH PosoH, acitizen of the United States of America, and a resident of St. Paul, in the county of Ramsey and State ofMinnesota, have invented certain new and useful Improvements ina Combined Trap, Filter, and Air-Distributer, of which the following is a specification.

Fig. 1.

My invention relates to improvements in a combined trap, filter, and air-distributer, and is more particularly adapted for use in connection with beer-pump apparatus.

The object of my invention is to provide a system of air-tubes and a trap for filtering the air and collecting and removing the impurities of the beverage in the pipes.

A further object is to produce a combined trap, filter, and air-distributor, which is in use cleanly and convenient.

In the accompanying drawings, forming part of this specification, Figure 1 is a diagrammatic view of a beer-pump apparatus, showing my combined trap, filter, and airdistributer connected thereto. Fig. 2 is a side elevation. partly in section, of my invention. Fig. 3 is a section of Fig. 2, taken on the line X X; and Fig. 4 is a detail vertical section of Fig. 2. p

In the drawings let A represent the combined trap, filter, and air-distributer, which consists of the upper and lowersocket-plates 3 and 4: for holding the hollow glass cylinder 5 between them by means of the tie-rods 6. These tie-rods pass through the upper socketplate and are threaded at 7 into the lower socket-plate. Washers, such as are indicated at 8 in Fig. 4, may be inserted between the ends of the cylinder and the socket-plates for the purpose of making air-tight joints and I preventing the cracking of the glass when the plates are fastened. The socket-plate 3 has with the air-tube 11, which projects downward through the cap and into the glass cylinder 5. The air-tube connects with the nipple 12, which is for the purpose of connecting with the air-supply tube B, as shown in v The cap is also provided with the threaded

openings

13 and 1. 1 for the outletpipes C and D. The lower socket-plate 4: is

formed with the downwardly-projecting por-.

tion 15, which terminates in an opening 16, as indicated in Fig. 2, and is threaded at 17 for the purpose. of receiving the cap-screw 18 for closing the opening. This cap-screw is pro- ;vided with the Garms 19 for convenience in is placed on the air-tube 11 through the hole 24 and abuts against the shoulder 25 on the air-tube. The portion of the air-tube within the strainer is perforated at 26, and the inclosure 21 is filled with suitable filtering material S, which is adapted to filter the air as it is forced through the air-tube into the cylinder. vided with a depending rod 27 and thumbscrew 28, by which the inclosure 21 is fastened in the cylinder.

In use the combined trap, filter, and airdistributer is connected with a beer-pump apparatus. This apparatus may be of any ordinary formsuch, for example, as shown in Fig. 1, which is as follows: The tube B con-.

nects with the the reservoir F and carries the pressure-gage 29. The pipes C and D connect with the bungs and draft-tubes G and H. These bungs and draft-tubes are of ordinary construction and are adapted for use in connection with the kegs I and J to draw the beverage therefrom. The draft-tubes are connected with the draw-01f faucets K and L by means of the pipes M and N. The valves 0 are shown interposed in the pipes M and N, so that either one orthe other, or both, of the kegs may be used. The air-valves P are connected with the pipes O and D for the same purpose.

Obviously a number of additional kegs may be added to the system, if desired.

In operation the air-reservoir may be filled to the desired pressure by means of the pump Q. When filled, the valve R is closed and the valves P opened. If it is desired to use The lower end of the air-tube is prothe beverage in both kegs I and J, the valves.

0 are opened and the faucets K and L used to draw off the beverage. When the system is in operation, sediment and impurities in the beverage are forced out of the kegs by effervescence and gradually collect in the air-distributing chamber A. These impurities are visible through the glass cylinder and may be drawn off through the cock 20. Should the amount of sediment become too great for removal through the draw-off cock, the cap 18 may be unscrewed. As the air enters the distributing chamber through the airtube it is purified by the filter. Obviously this is desirable, for usually the air that is used in connection with the'system is damp and foul, and the filter overcomes this objection. When the filtering material absorbs and becomes saturated with the impurities in the distributing-chamber, it may be cleaned by separating the parts of the distribute! and filter and the filtering material in the inclosure 21 renewed.

It is obvious that this invention may be used in connection with other air or gas apparatus than that described.

Having described my invention, what I claim as new, and desire to protect by Letters Patent, is

1. Acombined trap and air-distributer, consisting of a cylindrical receptacle, upper and lower plates in which the ends of said receptacle are soeketed, tie-rods by which said plates are fastened on said ends, a removable cap on the upper plate having air inlet and outlet passage-ways, a tube depending from said cap and connected with the air-inlet, said tube having a series of perforations, a filter surrounding said perforations, and means for removably fastening said filter to said tube.

2. In combination with beer-pump apparatus, a system of air-tubes having a combined trap, filter and air-distributer, a receptacle. a removable cap on said receptacle having airoutlets therein, an air-inlet tube on said cap and projecting downward in said receptacle, an air-filter connected with said air-tube in said receptacle, means for detachably supporting said filter on said tube, and means for emptying said receptacle at the lower end thereof, for the purposes specified.

3. A device of the class set forth, consisting of a cylindrical receptacle 5, upper and lower socket-plates 3 and 4, tie-rods 6 by which the cylinder is held between said plates, a removable cap threaded on the upper socketplate, an air-tube projecting down from said cap and into the upper end of said receptacle, a nipple 12 on said cap and connected with said tube, perforations 26 in the projecting end of said tube, an air-filter E surrounding the perforated end of said tube, a rod 27 depending from said tube, a thumb-nut 28 threaded on said red by which said filter is fastened on said tube, outlet-openings l3 and 14: in said cap, and a draw-off cock 20 on the lower end of said receptacle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH POSGH.
