Application filed December 9, 1914. Serial No. 876,274.'

To all whom it may concern Be it known that I, GEORGE S. NEELEY, a citizen of theUnited States, residing at St. Louis, State of Missouri, have inventeda certain new and useful lmprovement 1n Gas-Purifiers, of which the following isa full, clear, and exact description, such as will enable others skilled in the art to which 1t appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whichV y.

Figure 1 is a vertical sectional View. of a gas purier of my improved construction, the same being associated with an ordinary gas regulating valve.

Fig. 2 is a vertical section of a portion of a gas regulating valve having a part of my improved purifierl formed integral therewith.

Fig. 3 is an enlarged horizontal section taken approximately on the line 3-3 o Fig. 2.

Fig. 4 is an enlarged horizontal sectiotaken approximately on the line 4-#4 of Fig. 2.

. My invention `relates Ato a gas purifier particularly designed forl use in connection with the gas regulator which is located in 30 the connection leading from the street main to thev piping of a building, and my improved device can be made a part of and connected directly to the regulator, or it may belocated in the pipe which leads from the street main to said regulator.

The principal objects of my invention are, first, to provide a comparatively simple and inexpensive purifier or iilter which is adapted to be located immediately below or in purifier will be effective in eliminating from the gas passing through the regulating valve l and into the piping of the building, all foreign'substances, such as dust andy rust from the interior of the street mainsv and service pipes. y

My :improved purifier is particularly invtended for use in connection with high pressure systems, and in this connection it will rbe understood that in the systems now in general use for city lighting and heating, the street mains carry a pressure of approximately forty pounds, and in the service pipes in the buildings, the pressure is `approximately six or eight-tenths of a pound.

fron-t of 4the regulating valve and which lt will be understood that in gas distribution it is necessary to make use of regulating valves for the purpose of reducing the pressure between the street mains and the point of use, and it is, of necessity, a requirement that these gas regulating valves be accurate and positive in action.

The ordinary regulating deviceisequipped with a valve having a exible member of leather, rubber or analogous material which normally rests on a flat seat and closes the orifice in said seat. A source of much of the trouble and inoperativeness in gas regulating valves, is due to the fact that small particles of foreign substances such as dust or rust which forms on lthe inner surfaces ofthe street mains is carried by the gas into the regulating valve and lodges on the seat or lthe compressible member of the valve, thereby preventing a tight joint between said valve and seat, and permitting leakage from the comparatively high pressure street mains to 'the house pip-ing. As a result, seal blows often occur, the same being attended by considerable danger inasmuch as they frequently result in explosions and asphyxiations. Furthermore, seal blows are 'very destructive to` painting on the exterior ef buildings.

ln actual service conditions it has been Vdemonstrated that in gas distribution systems where high pressures are used, practically/forty o-r fifty per cent. of complaints in gas service is due to trouble in the regulating devices, and this trouble in turnis directly traceable to leakage of gas through the valves of said regulating devices. yAs a result much time, labor and consequent eX- pense i the regulating devices and cleaning the valves thereof, and I propose to eliminate all s involved in opening the housings of this trouble and expense `byproviding a sim-I ple gas purifier in the form of a mechanical filter, the same being located immediately adjacent to thev regulating device, thus preventing all dust, regulating device and interfering with the proper operation of the valve-therein.

A further object of my invention is to provide a purifier and ilter with one or more beds or layers of i'brous material such-as mineral wool, the same being slightly imrust, etc. from entering the Y pregnated with oil, andthus as gas flows through the purifier it will absorb and carry with 1t a certain amount of oil which, in

A turn, will be deposited onto the valve and valve seat, thereby providing sufficient lubrication to insure the proper operation of the valve and tion. A With thel foregoing and other objects in view, my invention consists in certainnovel features of construction and arrangement of parts, hereinafter more fully described and claimed.

In the form of device maintain it .in serviceable condiillustrated in Fig.

l 1, designates the housing of the regulat- Y of the housing 14 and below the fi'Xed ring 15 immediately the housing ing device, 11 the valve therein, and 12 the lsupply/pipe leading to the piping of the is a series of rings 17 each being provided with a section 18 of foraminous or reticulated material and positioned between said removable rings are layers or beds 19 0f l brousmaterial such as mineral-wool, the same being preferably impregnated to a slight degree with a suitable liquid lubricant such as oil.

In order to prevent extremely fine particles of dust andrllst from passing through the foraminous or reticulated plates, sections of woven fabric 20 such as muslin; are positioned on top of and below each layer of fibrous material. This arrangement not only holds the fibrous material in layer form but also prevents any `small particles of liber from passing out of the filter with the filtered or purified gas.

Positioned in the lower portion of the .housing 14 'and bearing against the lower one of the rings 17 is a compression spring 14a which normally exerts pressure to hold all f the rings in proper position in the upper portion of said housing.

' In the form of device illustrated in Fig. 2 a tubular housing 21 is formed integral with the housing of the regulating device and connected to the lower end of said housing 21 is the gas supply pipe 12a.. Removably positioned in the upper end of the housing 21 is a plate 22 which serves, asa seat for the valve 11a vice, there being an orifice 28 formed in the 4center of said plate and which orifice is normally closed by said valve 11a. v

Screw-seated in the upper portion of the housing 21 is a ring-nut 24 which rigidly fixes the plate 22 in position.

of the regulating de The housing 21 in this form of device is I provided with a series of removable rings, l

terial and thus all impurities such as dust,

rust, etc., will be removedfrom the gas and it will enter and pass through the regulating device in a thoroughly purified condition.

The gas in passing through 'layers of fibrous material will absorb a certain amount of the lubricant withwhich a portion of the fibrous material is impregnatedv and this lubricant will be absorbed by the leather I on the regulating Valve, thereby maintaining said leather in a pliable condition.

The device can be readily taken apart and assembled, thus facilitating repairs or renewal of the layers of fibrous material and by providing the readily removable nut 24 and plate 22,1 the valve of the regulating device can be easily and quickly removed in case of repairs or adjustment. A purifier and filter of my improved construction is `comparatively simple, can be cheaply manufactured, is effective in removing from the gas .enteringj the regulating valve all-foreign substances, such as dust, or rust, and consequently practically all of the trouble now arising from leaky regulating valves is entirely eliminated.

It will be readily understood that minor changes in the size, forin and construction of the various parts of my improved purifier and filter can be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth 1n the appended claims.

I claim:

A combined gas purifier'and lubricator for high pressure gas regulating valves, comprising a housing, a section of reticulated material fixed within said housing near one end thereof, a series of rings removably pos1- vtioned in said housing below the fixed section of reticulated material, a section 0f reticulated material carried by each ring, and layers offibrous material between sald rings and sections. of reticulatedy material, said layers of fibrous material being impregnated with liquid lubricant.

2. A combined gas purifier and lubricator for high pressure gas regulating valves, comprising a housing, a section of reticulated reticulated material carried by each ring,
