Jan. 24, 1939. o. B. GOLDKAMP FLUID CLEANER Filed May 31, 195s INVENTOR. Oo B. Gold/(amp ATTORNEY.

atented Jan. 24, 1939 i t ATES PATENT oltFlcE FLUID CLEANER ration-of California.

cleaner, more particularly adapted for use for cleaning commercial gas entering the service meter in gas system and the objects of my invention are:

First, to provide a cleaner of this class with noveld cleaner supporting means;

Second, to provide a fluid cleaner of this class with a novel cleaning member;

Third, to provide a fluid cleaner of this class with novel means of securing the cleaning member in position;

Fourth, to provide a fluid cleaner of this class which may be quickly and easily disassembled for replacing and cleaning the cleaner members;

Fifth, to provide a fluid cleaner of this class which is readily applicable for use in connection with the inlet to various kinds and classes of meters; and

Sixth, to provide a fluid cleaner of this class which is very simple and economical of construction, easy to install, eilicient in its action, and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a side elevational view of my cleaner shown ready for attachment as desired; Fig. 2 is an enlarged longitudinal sectional view thereof taken from the line 2--2 of Fig. 1; Fig. 3

is a transverse sectional View taken from the linev 3 3 of Fig. 2; and Fig. 4 is a lower end view taken from the line 4-4 of Fig. 2.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawing.

The casing member I, bushing member 2, cleaner member 3, and cleaner supporting member 4 constitute the principal parts and portions of my fluid cleaner.

The casing member I preferably consists of a pipe nipple which is externally pipe threaded at one end la and at its other end lb and is internally pipe threaded at the one end at Ic. Screw threaded in the threads Id by means of conforming externals threads 2a is a bushing member 2 which is substantially one-half to three-quarters of an inch in length and is provided with an internal thread 2b leaving a rela- K `Otto B.

, 'n r u "-f u "Mf""4`Claims. (Cl. 18S-73) g. invention relates to a nula tively large screw threaded central opening 2c. The normally lower end of this bushing 2 is provided with oppositely disposed slots 2d adapted to receive a spanner wrench for removing said bushing when desired.

Screw threaded in the threads 2b in the bushing 2 in a substantially loose manner is the one` end of the cleaner supporting member 4 which is a coil spring so constructed that the convolutions of the coils at one end are substantially together so as to thread to a certain extent in the threads 2b of the bushing 2 and this cleaner member has convolution spread some distance outwardly from the bushing 2 to near the opposite end, then has two or three of the coils positioned together as shown best in Fig. 2 of the drawing to provide a substantial support at the extended end of the cleaner member 3. Interposed between the threads 2b of the bushing 2 and the close convolutions 4a of the cleaner supporting member 4 is the one end of the cleaner member 3 which is a bag like member preferably composed of Pequot sheet cloth which is formed to fit snugly over the supporting member 4 and the open end is compressed between the close convolutions 4a of the member 4 and the threads 2b of the bushing 2 and the bushings 2 screwed tightly thereon thus forming a compact, tight union between the bushing 2, cleaner member 3, and cleaner member supporting member 4 so that the cleaner member may be quickly removed by simply unscrewing the bushing 2 from the support 4 which releases the cleaner member 3 and it may be cleaned or replaced.

It has been found that Pequot sheet cloth is the most suitable material for the cleaner in connection with the support 4 after considerable experimentation.

Though I have shown and described a particular construction, combination, and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

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

l. In a fluid cleaner of the class described, a tubular casing member, a hollow bushing member screw threaded in one end thereof, a lter supporting member including a spring-like member provided with close convolutions at one end loosely screw threaded in said bushing, and a fabric sack-like member positioned over said lter supporting member with its open end compressed between the close convolutions on said supporting member and the interior threads of said bushings.

2. In a fluid cleaner of the class described, a tubular casing member, a hollow bushing member screw threaded in one `end thereof, a filter supporting memberincluding a spring-like member provided with close convolutions at one end loosely screw threaded in said bushing, a fabric sack-like member positioned over said filter supporting member with its open end compressed between the close convolutions on said supporting member and the interior threads of said bushings, said casing consisting of a pipe nipple, pipe-threaded at its opposite ends externally and screw threaded internally at one end to receive the bushing.

3. In a fluid cleaner, an internally threaded bushing, a spring-like filter supporting member provided with close convolutions adapted to fit loosely the interior threads of said bushing, and

member provided with a thread-like exteriorv and a bag-like fabric filter member with its open end compressed between said supporting members interlocked by said thread-like portions.
