The invention relates to means for controlling fluid flow and pressure, andhas particular reference to devices which are introduced in the branches or near the outlets of a piping system having a number of outlets, in order to limit a desired maximum pressure and/or flow at or adjacent each outlet. Thus, in fireprotection standpipe systems in buildings, owing to hydrostatic head and the resistance to flow through pipes, the working pressures at different floors would ordinarily vary, and some or all of thesepressures would usually be too high to enable an inexperienced person to. handle the hose satisfactorily or safely. In such systems it is therefore important to provide the branches with devices which are set when or before the system is installed for predetermined discharge pressures,'which pressures are usually designed to be uniform for all outlets, though this is not necessarily the case. Each regulating device is capable of being set to determine the pressure adjacent its outlet without affecting the pressures at other outlets, and irrespective of the supply pressures in the system, provided that those pressures are mate rially above the maximum intended discharge pressures.

The object of the present invention is to provide a simple, effective and reliable device suitable for such purposes wherein the regulation isobtainedby positioning in a longi tudinal direction an internal obstructor the position of which relative to a gateway is determined by relative rotational adjustment of coupled waterway members within the bore of which the obstructor is axially disposed. In this respect the invention is es-' sentially distinguished from a device such as disclosed in my prior Patent No. 1,344,383, dated June 22, 1920, wherein apertured partitionmembers are fixed inside two coupled members, to partake directly of any relative rotation between such members.

A further object of the invention is to pro-' vide a device of the nature set forth in which the construction and relations are such that at the closest regulation which can be effected a certain minimal passageway is mainwhich may be understood forward end 6 to receive another'conduit sect1on 7 which may be part of a hose connec- Still another object is to providea virtually permanent locking device for securing the coupled waterway members in the predee terminedsetting, so as to" guard against the setting being tampered with, this locking de vice being adapted to be broken or forced in case of emergency in order to enable firemen or others to increase the pressure or flow at the outlet. It will be understood that the utility of the invention is not limited to the particular important field which has been indicated, and that the device may be applied to various pipes lines or systems, outlets or nozzles, where n its capabillties may be availed of.

In the accompanying drawings forming part hereof:

Fig. 1 is an elevation of one embodiment of the invention connected between portions of two other members of a conduit, one of which is shown in elevation w I Fig. 2 is a longitudinal section taken on the line'2.2 of Fig. 1;

Figs. Sand l are cross-sectionstaken on the lines 3+3 and 44C, respectively, of Figs- 1and2;and I Fig. 5 is a longitudinal section taken in a plane at right angles to Fig. 2, illustrating a modification.

The device includes two coupled coaxial waterway members 2 and 3 of generally tubular or annular'nature, the member 2 being 7 the inlet member and 3 the outlet member. 5 Themember. 2 is internally threaded at its rear end 4 to screw onto a section of pipe 5,

to represent part standpipe or other system. externally threaded at its of a branch of a The member 3 is tion. a V

The forward end 8 of the member 2 is enlarged to form a annular circularrecess within which fits the rear end of the" member 3, this rear end having an annular outwardly projecting rim 9 and an internal IlbJOPP'OT- tion' 10 defining a gateway 11. i i

The interfitting portlons of the3-members 2 and3 are adapted for tight connection per; mit'ting the membersto' be turned; relatively to each other about the common axis. A gland follower ring 12 enters within the recess between the outside of the member 3 and the surrounding. enlarged portion 8 of the member 2, and between this ring and the rim 9 a packing member 13 is interposed to be compressed by pressure between theparts 9 and 12.

The portion 8 of the member 2 is screw threaded on the outside to. receive a coupling nut 14, the flange 15 of which bears against thememben. The nut 15 is-disposed at a suitable distance forwardly from the gateway 11, and extending through it is a screwthreaded stem 17 of an obstructor 18, this obstructor cooperating w1th the gateway 11 to determine a desired control passageway, which passageway is capable of being adjusted. v

In the best embodiment, the obstructor 18 is a broad truncated conical element or head,

which stands within the gateway so as to be circumferentially spaced from theboundary portion 10.

The forward portion of the obstructor preferably projects within the bore o'f'the before installation,

member 2 to engage with one or more longitudinal inwardly prO ecting guide ribs 19 formed in this member, the obstructor hav- 40.

mg longitudinal slots 20 in its outer portion to cooperate with the guide ribs. By this means the obstructoris restrained against rotationrelative to the member 2 but is allowed to be shifted longitudinally. ',It will be perceived, therefore, th a't by turning the members 2 and 3 relatively to each other the effective-size of the annular control passage around the obstructor can be adjusted in a very definite and exactmanner to predetermine a precise maximum pressure and rate of discharge at the outlet when the shut-off valve (not shown) of thejpipe line or branch is opened. 1

The regulator is'preferably set at the shop,

and to assist in such setting the outside of the member 3, in front of the coupling nut 14, is marked with graduations 21, and the nut 14 with an index 22.- In this connection,.it may be observed that the coupling nut, 14 when set tight enough to preclude leakageis in effect fixed to the mem her 2, and that the relative rotation between the members 2 and 3 may be effected by turn- 1 ing the member 3 within the gland without disturbing the said nut. In order-so to turn 7 the adjustment.

the member 3 it is provided with a stud projection 23 adapted for the application of a spanner wrench.

Special means are provided for locking the members 2 and 3 in the predetermined setting in a sufiiciently permanent manner to guard against tamperingor accidental shifting of To this end, after the adjustment has been made, an arm 24 having a covered socket 25 at its free end and a widened base 26 is fixed to the nut 14 in such a manner that the socket engages over the end of the stud 23. A virtually fixed connection between the locking armand the member 2 is secured with advantage by tightly affixing the base 26 to the nut 14 by screws 27 ,the holes for which in the nut'are drilled and tapped after the adjustment has been made. I

By making the piece 24 of a casting capable of being broken by a sharp blow of 'a hammer, or by so forming it that-it may be distorted by the application of considerale force, the members can be unlocked by'firemen or othersin event of it becoming necessary to increase the area for flow. a I I y In connection with the foregoing features, provision is made within the regulator so that at the lowest regulation possible with the device a passage for a'certain amount of flow remains unclosed. This is preferably accomplished by making the extreme diameter of the obstructor 18 somewhat smaller than the diameter of the gateway 11, as indicated in Figs, 2, 3 and 4, so that a narrow annular this feature may involve a relation 7 portion of the obstructor, even though itmay not be smaller than thearea'of the gateway,

is spacedslightly from the boundary. Again, openings, such "as the notches 20, for example, maybe so arranged as to leave a minimal passageway through or around the obstructor at the closest possible adj ustment. The particular plan wherein the obstructor is made smaller than the opening or bore with reference to which it is adjustable possesses special advantages in simplicity, reliability and 'economy of manufacture.

' The shoulder 29 also prevents the obstructor being drawn out of engagement with the guides 19, and a collar or shoulder 30ion the stem at the opposite side of the nut prevents e the stem from being screwed entirely out of vthe nut, or the. obstructor being moved :out

of engagement with the guides in the reverse direction. v r v p A reasonfor providing for a minimalipas sage through the regulatoris that it should be assumed that occasionally, through error,

or otherwise, one of the devices in a system may be in a closed condition. In that event, if it were not for the existence of a restricted flow opening, impossible to close, a person on opening the shut-off valve of the branch or line and finding no flow would be likely to conclude that a main valve in the basement of the building, or elsewhere, was closed, and valuable time might be lost while he went to seek such a valve. To obviate such a difficulty this invention provides for at least a tell-tale flow under any condition of adjustment of the device. If on opening the ad jacent shut-off valve (not shown) the person should find that only an inadequate flow was delivered, he would know that the regulator was improperly adjusted and would break the locking device and turn the member 6 to shift the obstructor to a more open condition.

In the construction illustrated in Fig. 2, the broad end of the obstructor 18 is opposed to the upstream pressure. In order to make it easier to move the obstructor in the direction for wider opening when water is flowing through the regulator, the obstructor may be reversed, as in the case of the obstructor 18 of Fig. 5. The other parts shown in this view, being similarto those of Fig. 2, are designated by the same reference characters. The guides 19 of Fig. 2 project endwise somewhat beyond the bore of the member 2, and in Fig.

5 it is desirable that the guides 19 extend farther in this direction.

It will be understood that the invention is not limited to the precise form and details which have been described, and that certain parts and features may be used without others. For example, the locking means included herein may be employed with specifically different regulator elements, for instance those disclosed in my Patent 1,344,383.
