DISTRIBUTING-VALVE.

2" 0 all whom it may concern.-

Be it known that I, VIoToR H. BECKER, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Distributing-Valves, of which the following is a full description, reference being had to the accompanying drawlngs, in which- Figure 1 is a section; Fig. 2, a top View, some parts being shown in section; Fig. 3, a

front elevation; Fig. 4, a top View of the plug 1 removed from the other parts.

In refrigerating-machines in which ammomm or other fluid is used it is common to distribute the fluid from a header to a series of coils or pipes, each passage from the header to each coil being controlled and regulated by a valve. As such valves have heretofore been constructed, the opening has been large, and it has been difficnlt to properly regulate the flow of the fluid, as a slight movement of the valve greatly changes the size of the passage which it controls.

The object of my invention is to provide a valve which, when open, will present a small opening of about the proper size to allow the des1red quantity of fluid to pass, which can be easily closed and opened, which can be easily cleaned in case the passage becomes closed or clogged, which I accomplish as illustrated in the drawings, in which- A 1s a casting having a passage, or, through it. b are screw-threaded openings communicating with the passage (1, into which openings short tubes 0 are secured. These tubes and the parts b take the place of the ordinary header, and the fluid is to be introduced into this header in a suitable manner.

B is a cap, which enters the recess at the top of the casting A. This cap is provided with flanges d, one on each side.

6 are corresponding flanges on the casting A.

f are screw-threaded bolts, by means of which the cap .8 is secured in place.

9 1s a packing.

h isa plug fitting into the walls ofA, as shown in Fig. l.

i is the stem of the plug.

j is a space beneath the lower end oft-he plug.

is is a passage through the plug, which is tapering, and. is very small at one end, as shown in Fig. 2, and indicated by dotted lines in Fig. 1.

0 is a pipe leading from the valve to the coil. Zare flanges upon the lower end of the cast -ing A.

m is a screw-threaded coupling upon the pipe 0, provided with flanges a, corresponding with Z.

0 are bolts.

1) is packing.

r is a thumb-screw fitting an opening, .9, in the wall of the casting A, opposite to the plug h. A similar thumb-screw and hole are provided on the opposite side of the casting. (Not shown in the drawings.)

The dotted circular line in Fig. l on the plug indicates the position of the thumb-screw r and the hole which it closes.

In use, when the plug is in the position indicated in Fig. 1, the fluid which flows from the header will pass through the small hole in the plug, then through the passage 70 in the plug to the passage a, then through the passage a and the pipe 0 to the coil with which 0 is connected. part of the passage a which is lettered a, so as to close the opening into the plug, it can probably be removed by first turning the plug into the position shown in Fig. 2, when the accumulation will pass into the large opening 70, and then, by turning the plug back to the position shown in Fig. l, the pressure of the fluid will probably force the accumulation from k. The passage through the plug can also be readily cleaned by turning it one-quarter of the way around, which will effectually close the passage a, and then, after removing the set-screws r, a wire can be run through the holes 8 and the passage k.

The passage can be cleaned without removing the plug, without any escape of fluid.

The small hole in the plug must be atfirst made as nearly as possible of the proper size, to permit the flow of the required quantity of fluid.

Where a number of these valves are used With a common header, the fluid from the header will pass to each one of the valves, and a uniform quantity will flow through each valve. This valve may be used in other places where it is desirable to provide for the flow of a small uniform quantity of fluid.

If solid matter accumulates in that For convenience the position of the passage is through the plug may be indicated on the top of the stem t, as shown by dotted linesin Fig. 4.

I disclaim a distributing-valve plug having an inlet-chamber at one side and a contracted exit-passage at the opposite side, and confine myself to the plug with the special form of aperture herein shown.

What I claim as new, and desire to secure by Letters Patent, is-

In -a distributing-valve, the casing or body having passages on a, hole 8 in one of its sides, and plug 1', fitting to said hole, in combination
