MORTIMER B. MILLS, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE BOGUE & HILLS MANUFACTURING COMPANY, OF SAD IE PLACE.

VALVE.

SPECIFICATION forming part of Letters Patent No. 397,088, dated January 29, 1889.

Application filed November 23, 1888. Serial No. 291,700. (No model.)

To all 1071/0722 it may concern.-

Be it known that l, MORTIMER l5. MILLS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Valves, of which the following is a specification.

My invention relates, more particularly stated, to the class of water-supply and shutoff valve devices of the kind commonly employed underground in various connections as means for turning on the water-supply and shutting off the same, and with the latter operation effecting the discharge of waste water contained in the supply pipe or pipes leading from the valve device, and especially in that portion. of the latter which may be aboveground.

The object of my improvement is to provide a valve device of the above-mentioned description, the peculiar construction of which shall render unnecessary any form of packing, not even white lead, to elfect impervious joining of the parts, but which shall comprise parts involving such construction as to per mit them, after being cast, (if formed by casting,) to be readily planed so smooth that where they are bolted or clamped together the junction shall be accurate in a degree to render them practically integral to the extent, even, of being impervious at the joints to air.

By means of my improved construction, there being no need of employing therein any form of packing, whiclris generally the first part of a valveto wear out after the device is once placed underground, where access to it, as to any other, is attended with considerable inconvenience, my improved valve de-' vice need not be disturbed, as do at times those requiring to be packed, to repair the packing of the joints; and, besides, my improvement affords a valve device of exceptionally cheap construction.

My invention consists in the (OHSU'HCtlOH hereinafter set forth and claimed.

One of the several connections in which the class of valve device to which my improvement relates is ordinarily employed is as a so-called fire-plug, this being the apparatus commonly provided in cities at and between the street-corners and to which the fire-engines are connected to receive their supply; and for convenience the description hereinafter contained refers to my improvement as adapted for use in a fire-plug, and it is so illustrated in the accompanying drawings, in which.

Figure 1 shows my improved device, as adapted for use in a fire-plug, in vertical section; and Fig. 2 is a perspective view of a detail.

A is the shell, the central part, B, of which is in the form of a double, T, having a passage, 0', formed longitudinally through its shank-q, and having in one head, 19, preferably at each side of the shank and close to the latter, an opening, 0.

C is a cap, having a flange, n, extending 'laterally from its open. end and provided in its base with a perforation, m, which may be threaded, as shown, to permit a water-supply pipe, D, to be screwed into it.

The cap C is secured at its flanges n by bolts Z to one head of the double T, and, like the latter, may be planed off to render the parts where they are brought into contact quite smooth to form between them an accurate and impervious junction. The interior of the cap 0 affords a chamber, 7t.

C is a cap like the cap C and similarly secured to the double T B at the head thereof opposite that at which the cap C is secured, the interior forming a chamber, 7s.

The cap C is perforated, as at on, the opening being, like the opening on through the cap C, preferably threaded to permit the outletpipe D to be screwed into it. hen the device is used in a fire-plug, the pipe D should have a lateral branch, 72, to extend to the side of the fire-plug and permit connection with the latter of hose, in the usual manner.

E is a rod, which is sufficiently long to extend perpendicularly through the pipe D into the chamber k, in which it is provided with a valve, E, adapted to cover the adjacent end 5 of the opening 0 in the shank q, the rod E thus forming the stem of the valve E. Where the device is used in other connections than in a fire-plug, the valve-stem E need not extend through the outlet-pipe D, but may pass,

at one side off the latter, through the cap C, where it may be suitably packed to prevent leakage around it.

G is a metal bar, 1 )ertorated near its center, as shown at m, and bent toward its extremities, forming legs g and [feet f.

. cured upon the stem E (which passes through it at its perforatitiin {11) in a position to cause 5 the feetfto extend over the openings 0 in the j upper head, p, of the double T 13, and to:

cause valves c, guided by stems (7, which extend into the openings 0, as shown, to cover the said openings while the valve E is below and away from its seat at the end of the opening 1' in the shank q of the part 13. One valve c and opening 0 may suffice in my improved valve device, and my invention is intended to include such constructit'm. lwo, however, are preferred, as preventing by means of the duplicate stems d the possibility of the valvebar Gr becoming turned from its position wherein the valves c coincide with the openiligs 0.

To admit water through thedevice the stem E is lowered to remove the valve E from its \Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a valve device, the combination of a double T, B, having a passage, 0', in its shank, f and an opening, 0, in one head, 1;), flanged caps 1 C and C, secured at their flanges, respectlhe bar t is ively, to the heads, openings m and m in the respective caps, a stem, E, extending through the cap (1 and mssage r, and carrying a valve, E, in the cap 0, and a valve, 0, supmrted on the stem E inf' the cap 0 and extending over the opening 0, si'lbst'antially as described.

2. In a valve device, the combination 01. a double T, 13, having a passage, 1', in its shank, and an opmiing, o, in one head, 13, flan god caps (3 and secured at their flanges, respectively, to the heads, openings m and on, in the respective caps, a ste1n, E, extending tln-ough the cap (1 and passage 1', and carrying a valve, E, in the cap (7, a bar, G, secured to the said stem in the cap 0, and carrying a valve, 0, over the opening 0, and a stem, (7, extending from the valve into the opening 0, substantially as described.

A valve device comprising, in ct'nnbination, a double T, 15, having a passage, "13in its shank, and openings 0 in the head at 0pposite sides of the passage '1', flanged caps C and (l, secured at their flanges, respectively, to the heads, openings m and m, in the respective caps, a stem, E, extending through the cap (71 and passage r, and carrying a valve, E, in the cap 0, a bar, G, having legs 5 and feet-f and secured on. the stem E in the cap C, to cause the feet to extend over the openings o, valves 6 on the feet, and stems (1, extending from the valves c into the openings 0,

, substaiitiall as described.
