Application filed May '14, 1920; Serial no; 381,497.;

To all whom it may concern:

Be it known that L'JAMns A. PARENT, a citizen of the UnitedStates of America, residin at Detroit, in the county of Wayne and btate of Michigan, have invented certain new and useful Improvements in Gas- Pressure-Reducing Devices,, of which the following is a specification, reference being had therein to the accompanying drawings. This invention relates to a gas regulating device commonly known as a V gas saver,

and the primary object of my invention is to furnish agas pipe or other conduit with a novel form of bafl'le which will tend to retard the velocity of gas therethrough and consequently reduce the pressure tosuclija degree as to produce a savlng'of gas and better ignition at a burner.

Another ob ect ofm I 1nvent1on-'1s to prov1de a gas conduit with a series of articulated baffles providing a tortuous or sinuous passage for gas 1n the conduit, the baflles bein d1s .osed so as to revent ex- D cess ve pressure at an outlet, and in consequence of such baffles-1t 1s impossible for gas to flow throu h meters and 1nto burners at r a greater rate than can be recorded or used.

In the first instance, it-is-possible to provide a desired number of baffles to reduce pressure of gas a desired degree whereby a meter of limited capacity could be installed on a high pressure gas line. In the second instance, it is a well known factthatvarious types of burners cannot be adjusted for excessive gas pressures, so my bafiles may be installed to properly regulate the pressure of gas for a burner so as to insure proper combustion at the burner.

'A further object of my invention is to provide fluid bafiies for conduits with the baffles constructed to insure a thorough c0m-' mingling of the products of combustion, and also to prevent displacement of the baffles by gas pressure within the conduit.

The above and other objects are attained by a mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawings, wherein- Figure 1 is a longitudinal sectional view of a gas conduit provided with baflies which cooperate in producing a unitary result;

Fig. 2 is a cross sectional view taken on the line II-II of Fig. 1; 1 r

I Fig. 3 is a perspective iew of'an initial or conical pressure reducing member, and 1 Fig.4'is a perspective view of a secondary or disk pressure reducing member Assho'wing a conventional form of gas conduit, the reference numeral 1 denotes" a pipe having one end thereof connected by a sleeve t a j e P pe 3, and the opposite end f. th pipe 1 has conven: V v

tionalform of union connection t with a pipe 5: The connections or coupl1ngs2'an'd 1 permit of the'pressure, reducing member Specification of Letters fatent. Paigght ed; lvlay being-easily installed within the pipe 1, and reference will'first be-had to'the initial pressure reducing member associated withthe coupling & andshown in Fig.3. The

initial pressure reducing membercomprisesa cone 6 havlng tsjlarge end provi'dedwithj a peripheral flange 7 and this flange may be seated against the end of the pipe 1',within"' the coupli'n'g l, with the small end 'o'f the cone 6 extending into the pipe; The flange 7"will prevent the pressure of -gas-from shiftinga conewithinthe-pipe 1, andwhen f' the gas impinges against the converging wall-s of the cone the gas is more or less baiiied' so that its flow is somewhat retarded and {its pressure reduced; 2 Mounted in the 1 large end of the cone 6 and axially thereof is a small cone 8 which is supported by opposed arms 9 having the ends thereof solfrom the cone 6 by having its innerend completely closed so that said cone will provide a pocket and positive baffle for gas enter ing the same. When the gas is retarded by the cone 8, it will be necessary forthe gas to flow over the edges of the cone to enter the cone 6 and the restriction or reduced passagebetween the cones 6 and 8 is sufiicient to further retardthe gas as it enters the large cone or conical member .6.

dered' or otherwise connected to the walls of the cones 6 and 8. The cone 8 differs The'secondary pressure reducing'member comprises a series of spaced d1sks 10 have ing diametrically opposed edges thereof notched, as at 11, to receive parallel arms 12 which may be soldered or otherwise fixed relative to the disk so that the same will be maintained in spaced relation. Ends of the arms 12 may be bent, as at 13 so as to form lugs which may be anchored between the ends of the pipes 1 and 3, within the sleeveor coupling 2 and with the arms so held it is practically impossible for gas impinging against the disk to dislodge the member within the pipe 1.

The peripheral edges 10 of thedisk are notched or cut away, as at 14 and one side wall of each notch bent outwardly from the plane of the disk to form a deflector 15, With each disk having a single notch and dfiector andno two notches in longitudinal alinement, it is obvious that gas must travel in a sinuous path through the pipe 1 and when encountering the deflectorsol5 a whirling motion will be imparted to the gas tending to further retard its passage through the chambers formed between the disk 10 within the pipe 1. The gas in seeking its passage through the secondary pressure reduc ing member will have its pressure reduced and when this secondary pressure reducing member is associated with the initial or conical pressure reducing member previously described, itis practically impossible for an excessive pressure of gas to pass through the pipe 1 and consequently there will be a saving of gas and better ignition regardless of the nature of gas passing through the pipe. As natural gas is more active or volatile than artificial gas it may be only necessary to increase the number of disks 10 to compensate for the activity of the gas.

Under some conditions it may be only necessary to use the initial gas pressure reducing member, or even the secondary pressure reducing member by itself, but the best results have been attained by using the members as shown in Fig. 1. Both of the pressure re ducing members may be made oflight and durable metal that will not corrode or deteriorate due to any moisture within the gas,

and since no alterations are required whatsoever in the conduit, it is obvious that the members may be easily and quickly installed. I would have it understood-that the size and shape of the pressure reducing members may be varied, and that any desired number of said members may be employed to attain a desired reduction in gas pressure.

lVhat I claim is 1. Means for reducing gas pressure within a conduit composed of joined pipes, comprising parallel arms having end lugs clamped betweentlie joined pipe ends of said conduit, and a series of disks carried by said arms and having notched edges with some of said notches accommodating said arms and other of said notches providing a tortuous passage from one disk to another.

2. The combination with aconduit composed of joined pipes adapted to have gas pass therethrough, of a cone open at one end only and supported axially of said conduit and providing a baflie, a cone surrounding and supporting the first mentioned cone, adapted to receive gas therefrom and restrict the passage of gas to the axis of said conduit, a series of disks within the conduit adjacent the last mentioned cone causing the gas to travel in a tortuous path impinging against the walls of the conduit, and means between joined pipe ends of said conduit preventing longitudinal displacement of said disks.

In testimony whereof I afiix my signature in the presence of two witnesses.
