T o all whom it'fmvay concern:

Be it known that we,CHR1sTi-AN N. QLs'EN and AXEL P. PETERSEN, -citizens yof the United States, residing atJersey City, in thecounty of Hudson and State of NeWJersey,

T e invention comprises the provision of a filtering medium and areceptacle for receiver ing dirt and extraneous matter and means for holding the filtering material and' recepta'cle in proper relations to each other.

' The 'invention further comprises the pro'- vision of a'ltering deviceformed of a plurality `of layersi of Wire netting arranged cones for receiving and distributing the gas over the entire surface thereof, and a drip.

receptacle positioned for receiving dirt Aand other extraneous matter from' the strainer, y. together with connection adapted 'to fit an ordinary gas pipe and at thesame time hold a receptacle and a filter in proper relation' to each other.

The object in view is the provision cfa ilterin medium arranged in the flow ofv gas A Whenv a ove a receptacle for receiving dirt.

Another object in view istheprovision of aV c onicallyshaped lter or strainer arranged in the ath of the flow of gas for lseparating from t e gas dirt and other extraneousmat'- ter contained therein, a receptacle positioned in proximity to the strainer for'v receivingiiirt therefrom and means vfor holding-the strainer and receptacle in proper relation to each other.

L With these and other objects inf'vieW the invention comprises certain novel constructions, combinations and arrangement of parts that Will be hereinafter more fully described and claimed. e

In the accompanying drawings: Figurev 1 is a side'elevation of the present invention connected up ready for use. Fig-2 is a longitudinallyverticalsection through Fig. 1,'the valve being omitted. f

In manufacturing gas and distributing .the same to pipes or mains various foreign substance or extraneous matter is mechanically suspended in the "gas andhis delivered With such Aextraneous matter either ta the pipes or suspended in thcgas from any register in the meter pnly t l .various-meanshave been provided with varylis firmly secured to pipe 5 genera ,desired may be simply forced' into pipe 5'and cylinders f -Wire netting fitte the gas. I Also it `liasbeen found that .various 'extraneous matter or `partielles taken lup by thefgas from the corrosion of the pipe, and

en from other sourc'eggat ers momentum as the same are forced along'and when striking the meter near the. point of'vdestination will greatly assist the gas in -operating the same. In order to therefore secure pure gas and .to-

Y epassage of gas,

ing successes, and-it is to this class of devices that the present invention relates.

Referring 'more particularly .to the drawings f1 indicates the pipe of any desired construction for containing gas and is designed ,to supplythev gasmeterlnot shown) with gas in the usual manner through pipe '2.` Secured in pipe 1 is avalve 3 of any deslred constructlonfor'letting ofl" the gas as may be desired.A Connectedto'pipe 1 is a T fitting 4 preferably of the' usual construction. e G0114v nected to iittingll is'af'short pipe 5 Whichin turn is connected to pipe 2 by means ofpnion 6.` Positioned in' ipe 5 is a lter'7 that' is formed with acy' ndricalportonf a held thereby friction., As shown in the `drawings conical-.part 9 isfsoldered to cylinlsimply `mixing the'wires and twisting the u l.same after lmixing or interlocking. The conical'portionV 9 is formed of va (plurality of .'g'rilfltoqeach other; the outer vcone'being the largest land theinner 'most' 'cone/the smaller, `so as to l form a plurality o? distinct cone-shaped sieves oriilters.arranged in succession against which the gask passing from pipe 1 to pipe 2 must impinge. yThe impingmg of agas against thefirst or outer cone will greatly clean the gas and remove a major part of the dirt an'd other extraneous matter from lthe gas. L Asthe gas continues through' the cone- -shaped member 9 it Will be further cleaned as it-kpasses through the res uective cones successively until it is almost a solutely' pure when it enters ipe 2.

Secured to 'tting or member 4 isa 'receptacle 1 1 that is preferably removably secured to member 4 as' by threads 12, Receptacle 10 may be of any'desired'size and is provided with a-bottoln or cap 13 that is removably secured in position preferably by threads 14..

The filter 7 is so arranged as to have the conical shaped members or portions 9 projecting toward the flow of gas and across the receptacle 11 so that all the dirt and other matter may fall into -the receptacle that is removed from the gas j It is to be observed that the filter or strainer 7 will -not onlylterthe gas in the usual acceptation of the word but will also catch all solid .particles which are mechanically suspended in the gas so that the same are deosited in a res`evoir or receptacle 11 and not orced through the meter, The forcing of l such solid particles through the meterhas a tendency to accelerate the speed of the meter and consequently register a greatervolume of gas than actually passes through the meter. i 4 A 1 In forming the conical-shaped member 9 the same may be formed of any'desired material as copper or brass and in distinct cones and secured together by solder. However, under some circumstances I wind wire netting into a conical-shaped coil and then secure the same to cylinder 8.

is more quickly andy cheaply, constructed. When the strainer is full of dirt or other eX- 4traneous matter the same maybe removed and cleaned in any desired Way and also the receptacle 11 may be cleaned by simply removing cap 13.

What I claim is: 1. .A strainer for'gas comprisinga casin a nettmg wound into a plurality of convoIu- This willl give the same effect as distinct cones and tions, means for holding the same in position and a receptacle for receiving extraneous matter therefrom. f

2. A strainer comprising a holder, a conical-shaped strainer formed froma plurality of conical-shaped sieves telescoped into each otherand in contact their entire length, and

means for receiving dirt from said conicalshaped strainer.

3. A strainer, comprising a holder, a dirt receptacle and a strip of netting wound into a conical-shapedstrainer having a plurality of layers, said strainer being in posltion above said receptacle for receiving dirt and deposing the same in said receptacle. 1

4. A 4gas strainer comprisinga holder, a dirt receptacle, a conical-shaped strainer in position above said receptacle and construct-- j ed of a plurality of conical shaped s'trainers formed of netting and positioned in Contact lwith each other through their entire length CHRISTIAN N.
