AIR-PURIFIER FOR BEER-PUMPS.
SPECIFICATION forming part of Letters Patent No. 609,493, dated August 23, 1898.
l Application iled February 5, 1898. Serial No. 669,214. (No model.)
To @ZZ whom, t may concern.-
Beitknown that LHENRY BnU'rELsPAcHER, a citizen of the United States, residing at Bridgeport,in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Air-Purifiers for Beer-Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to certain new and useful improvements in air-purifiers for beer pressurepnmps, and has for its object to provide a device which may be interposed intermediate of the pump and beer-keg, and whereby not only is the air from the pump purified, but the presence of any foreign matten-such as oil, water, or solid impurities-is readily detected.`
In the accompanying drawings, whichl form a part of this application, Figure 1 is an elevation of my improvement, and Fig. 2 a seci tional elevation of the same.
Similar numbers of reference denote like parts in both figures of the drawings.
Heretofore air filters and purifiers have been interposed intermediate of the air-pump and the beer-kegfor the purpose of removing y impurities and noxious vapors from the air 5 but as a rule the air from the pump has been discharged directly against and through the airpurifying material, the result being that such material in a short time has become saturated with various impurities, and consequently the air after passing through the purifying material thus deteriorated is laden with noxiousfgases and other impurities. Also, the air-pump is usually located beneath the bar of a saloon, where there is more or less accumulation of refuse, and it frequently happens that water, slops, and the oil used for the purpose of lubricating the pump are discharged through the filtering or purifying material into the been-keg, and such pollution of the beer can only be detected by the taste of the customer. My invention aims to cure these defects in a very simple and efficient manner and will be best understood from the following description.
1 is a plain cylinder, of glass, closedby caps 2 3 at the top and bottom, washers 4. 5 being interposed between these caps and the ends of the cylinder in order that the latter may be perfectly air-tight.
6 is a Irod which extends through the cyln inder and is threaded at each extremity, one end of the rod being secured within the bottom cap, while the other end is engaged by a nut 7, whereby the caps are drawn tightly together against the ends of the cylinder.
The upper portion of the cylinder contains purifying material 8, such as specially-prepared cotton or lime, cream of tartar, or charcoal, and this material is confined between perforated disks 9 10, the 'lower disk l0 being supported upon a shoulder 11 on the rod Gi.
12 13 are hollow nipples which extend out wardly from the top and bottom caps 2 3, respectively, and are in communication with the interior of the cylinder.
14 is a pipe which rises from the lower cap 3, inside the cylinder, and is in direct communioation with the lower nipple 13, this pipe extending upwardly and terminating in an overhanging gooseneck portion 15, immediately below the purifying material.
16 is an ordinary petcock which depends from the lower cap 3 and is in communication with the interior of the cylinder.
17 is a rubber tube connected with the upper nipple and leading to the beer-keg, and 18 is a rubber tube attached to the lower nipple 13 and leading to the air-pump.
19 is any suitable pin or spur which depends from the bottom cap and is inserted within any ordinary socket or hole, (not shown,) so that the jdevice may be supported in an upright position.
.Asthe air is forced through the tube 18 up through the pipe 14 it will not be discharged directly through the purifying material 8, but will be directed downwardly toward the bottom cap 8, so that any gaseous, solid, or liquid impurities will not be forced through the purifying material. 'The liquid impuri@a ties, such as water and oil, will settle upon the bottom of the cap 3 and can be instantly A detected by the bartender or by a customer, since my improvement is intended to be located in plain view above the bar. y The noxious gases usually present beneath the bar of a saloon are, as a rule, heavier than air, so that they will remain at the bottom of ICO the lower portion ofthe cylinder and will not interfere or become coinmingled with the air, which, owing` to its pressure, passes through the purifying material into the beer-keg. These gases, together with the liquid impurities, may be readily drawn off by means of the petcock 16.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. An air-purier for beer-pumps comprising a glass cylinder closed at the ends byairtight caps, hollow nipples extending from the upper and lower caps and communicating with the interior of said cylinder, connections between the beer-keg and air-pump and said upper and lower caps respectively, and the air-purifying material contained within the upper portion of said cylinder, substantially as set forth.
In testimony whereof I affix my signature` in presence of two witnesses.
