VALVE DEVICE.

Specication of Letters Patent.

Patented Dec. 21, '1909.

Application filed July 20, 1908. Serial No. 444,429.

To all whom it may concern:

Be it known that I, JOHN MILLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Valve Devices, ofwhicli the following is a specification.

One object of the invention is. to provide improved means for opening a valve which is normally held to its seat by means of a spring, and to this end a rod is arranged at right angles to the valve stem and an eccentric is arranged on the rod in position to engage the valve stem.

Another object of the invention is to provide means for permitting expansion and contraction of the various arts of the valve device without injury, an( to this end the valve casing is supported by rods extending from a slab or other primary support so that the valve casing and the valve-operating rod move independently of said support.

The invention consists in the features of novelty that are hereinafter described with reference to the accompanying drawings, which are made a part hereof, and in which:

Figure 1 is a vertical central section of a valve device embodying the invention. Fig. 2 is an elevation thereof on a smaller scale. Fig. 3 is a horizontal section, full size, on the line 3 3, Fig. l, with the eccentric in plan.

The valve casing, 1, has an inlet port, 2, and an outlet port, 3. The inlet port is surrounded by a valve seat, 4, to which is adapted a valve, 5, seating with the tlow of the water and held normally seated, by a coiled spring 6. The stem of the valve is guided by suitable means and its inner end projects into the chamber of the casing, 1, in position to be engaged by an eccentric 7, carried by a valve rod, 8, having a handle, 9, for turning it. The pitch of the eccentric is such that by turning it through less than a half-circle (sa 1550) in one direction or the other, it willyfully open or` fully close the valve as the case may be. will remain in whatever intermediate position it is stopped, and hold the valve in corresponding position-wholly or partly open. The movement of the eccentric in one dircction is .limited by the contact of shoulders on lts pitch is also such that itlugs 10 and 10a cariiedby the leccentric and casing, respectively, and in the other direction by shoulders 11 and 1l, the former of which is formed directly on the eccentric, while the latter is formed by a lug carried by the casing.

The valve rod is without threads. At its lower end it is supported and guided by a spider 12, in the outlet port 3, and at the upper side of the casing it passes through a stutlingv box 13. The screw cap or plug which cai-ries the stutling box is provided on its under side with a sleeve 13a which surrounds the rod and projects downward far enough to act as ,a stop for engaging the eccentric and preventing its upward movementfai' enough to disengage it from the valve stem. Above the stulling box the valve rod passes through a sleeve, 14, secured to a slab, 15, or other support. The upper end of the sleeve is provided with a flange, 16, which bears upon the top surface of the slab and is threaded on its exterior to receive a nut, 17, a plate, 1S, being interposed between tlie nut and the under side of the slab. With this arrangement, *when the nut is turned up, for which purpose it is provided, at 19, with a nonciicular portion for receiving a wrench, the plate will be firmly clamped against the underside of the slab or support and the sleeve will be firmly secured in place. in its opening through the slab. The plate has on its under side two tapped bosses, 20, and into these are screwed the threaded upper ends of two supporting rods, 21, lock nuts, being turned onto the rods and into engagement with the bosses. The lower portions of the rods pass freely through perforated lugs, on opposite sides of the casing, and below these lugs adjusting nuts, 24, are turned onto the rods for supporting the casing at the desired position with relation to the slab or support. The advantage of this construction and arrangement of the parts is that they are allowed perfect freedom oi movement relatively to cach other and are, therefdre, not liable to break or bind.

The improv `d valve device' may be used for various puiposes but is especially adapt cd for hydrotherapeutic. baths in which they tures which are sometimes not only suddenbut also both sudden and extreme. T A

The entire valve device is subgect to bodily up and down movement due to the expansion and contraction of the Waste pipe, 24:,

with which the outlet port 3 communicates,

' the Water limited to this and this expansion and contraction is so considerable that it frequently breaks the slab when the valve device is rigidly attached thereto. It rj'for this reason that the valve is freely movable on the rods 2l, and .the valve rod 8 is capable of moving endwise through the sleeve 14.

The sudden changes in the temperature of passing throughthe valve casing produces sudden relative changesv in the sizes, proportions, or relative positions of the several parts, due to their` unequai eX- pansion or contraction, and eiitreme changes due to these causes produce a considerable disturbance oralteration in the relations of the parts frequently resulting in their breakage, distortion, or other damage or injury whichl will prevent or materially interfere with the proper operation of.y the valve device.

It is, of course, known that an eccentric is one form of cam and I desire to have it understood that the present invention is not particular form. 'On the contrary a cam of any form that will accomplish the desired result is Within the scope of the invention. f
