THOMAS G. Mover, or CLEVELAND, OHIO.

. VALVE.

This invention relates to valves, and has.

particular reference to a valve for use in connection with vapor heating systems, al-

though it'will be obviousthat the same may be employed for many other purposes. However; its use in; connection with vapor heating systems presents certain advantages over other yalves heretofore employed, owing to the desirability of obtaining an accurate adjustment necessitated by the smallness of the pressures employed.

It has long been customary to provide the spindles of turning plug valves with pointers or projections which shall not only indivention to provide a device of this character cate at all times the position of the valve, but shall also, by cooperation with stops carried by the valve casing, limit the rotation of the plug in one or both. directions. Heretofore it has frequently been customary to make one or the other of these stops in the form of an adjustable stud suitably secured to a flange or ledge carried by the valve casing, so as to permit the plumber or steam fitter or other skilled person'to adjust the swing. of the valve to the amount necessary for the proper operation of the devices connected therewith. The further adjustment of these studs, has, however, been such an and obvious matter as to cause the users to shift the same in an attempt to obtain more heat or otherwise to modil the action of the apparatus with the result that the beneficial results of the'first adjustment have been lost, and the apparatus caused to operate unsatisfactorily.

ltis therefore the main object of this in in which the mode of adjustment shall not be apparent to the layman, although an easy and simple matter for the person who is acquainted therewith; the provision of a device of this character wherein the stop memher, in whatever of its adjusted positions it may be located, sh all appear to be at the extreme limit of its movement so as not to induce the user to believe that further opening is possible; the provision of a device Speciflcationof Letters Patent;

Application filed September 25,1913. Serial No. 7912682.

in which the adjusting and securing parts and stop may be varied as regards each other, and the valve itself; while further objects and advantages of the invention will become apparent as the description proceeds. Generally speaking, my invention may be defined as consisting of the combinations and constructions recited in the claims hereto annexed and illustratedin the drawings accompanying and forming a part of this application wherein Figure 1 is a side elevation of the complete valve construction in accordance with my invention; Fig. 2 is a vertical, cross-sectional view through the same taken upon the line 22 of Figs. 1 and 3; Fig. 3 is a plan view of the valve shown in Fig. 1; Fig. 4 is a plan view of the same valve, the handle and adjustable stop 'being omitted; Fig. 5 is a detailed perspective showing the separate parts.

of the handlefand adjustable stop in separatedposition; and Fig. 6 is a vertical,crosssectional view through a modified form of device. j j

- Describing the parts by. reference characters, 1 represents the body or casing of the valve, which is formed with suitable inlet and outlet nipples 22, disposed in'any convenient manner and formed between these nipples with a suitable seat for the movable valve member 3. Secured to'this movable valvemember is a rotatable stem 4, journaled within a suitable aperture-5 which is usual valve construction. The exterior of the extension 6 is preferably made of cylindrical form, as shown in Figs. 2 and 4, for

a purpose tobe described hereafter, the nut 8 being-sunk therein-for its entlre thlckness in the embodiment shown in Figsu'l to 4,

inclusive.

Carried by the casing or body 1 at the footof the extension 6 is a laterally projecting'ledge or flange 10, preferably having a fixed stop 11,-whereby the closing movement of the valve may be limited, and also, n the present embodiment, having a circularly arranged series of recesses 12-12, these recesses preferably terminating short of the lower face of the ledge or flange, as shown in Fig. 2, so as not to be visible from beneath the same. Mounted upon this-flange is an.

cides with the edge of the ledge or flange a and the lower face of the same is provi'ded with a stud 16, adapted to enter any one of the recesses 12 so as to maintain the plate in any adjusted position and secure it against shiftingfi The an ular extension of the plate 14 should be equal to the range of the adjustment desired so that the plate may cover all 'of the recesses which are to the rear of the one in use, while the forward extremity of the plate is preferably provided with some indication, such as the word open to lead the users to the belief that the valve is actually wide open when the mdicator arrives at thispoin v The projecting end'of the stem is squared or flattenedas at 18 for the reception of the member 19 which is provided, atone side, with the down-turned finger 20 whose end projects in proximity with the ledge or flange 10 so as to engage'the fixed and movable,stops. To the flattened portion of the stem, above the member 19, is attached the operating handle 21, the same being preferably separate from the member 19 so as to /permit it to be shifted to different positions as required by the proximity of thewalls, pipes and other obstructions. The handle 21 and member 19 are secured to thestem in any convenient manner, as by the screw 22.

, In order to conceal the movable character of the ring 15 and also to hold this ring sufliciently tight to the face of the ledge or flange 10, I cover and surround the extension 6 with a suitable cap, the same (in Figs. 1 to 5) comprising a cylindrical wall or hollow member 24 surmounted by an aper tured end-closure '25 which is adapted to surround the stem and overlie the gland nut 8. In this case the various parts can be dis mounted so as to permit the adjustment of the movable stop merely by removing the screw 22.

In the embodiment shown in Fig. 6, the exterior of the extension 6 is shown as threaded for the reception of the member 24: which, in this case, preferably terminates flush with the outer end of the extension,

the gland nut 8 being provided witha peripheral flange 26 overlying this member and. concealing its movable character. In this modification, the greater difficulty of dismounting the parts shields the adjustment yet further from derangement at the hands of unskilled persons.

While I have described my invention in detail, I have done so from the fact that the constructions here disclosed have been proven by expei ience to be particularly suited to the end in View. However, I do not propose to be limited to such details except as the same may be. positively included in the claims hereto annexed or may be rendered necessary by the prior state of the art.

Having thus described'my invention, what I claim. is

1. In an adjusting Valve, the combination, with a casing and a rotatable stem carried thereby, said casing having a hollow threaded extension surrounding said stem provided with a packing gland, and also having an exterior surface of revolution substantially concentric with said stem, of an adjustable member surrounding said extension and having a surface of revolution complementary to said first surface, there being a plurality of recesses in one of said surfaces and a projection extending beyond the other surface adapted to enter any one of s id recesses, the angular extent of each f said surfaces being suflicient to cause more or less of the said recesses to be hidden, a projecting part movable with said stem and arranged to engage a portion of said adjustable member whereby the angular movement of said stem may be limited, and means surrounding said extension and engaging said adjustable member, whereby it is held against said first surface and the fact of its adjustability is concealed.

2. In a device of the characterdescribed, the combination with a valve casing and a rotatablestem carried thereby, said casing having a ledge surrounding said stem and provided with an arcuate series of recesses, of a movable stop member surrounding said stem and having a seginentalportion adapted to overlie and conceal more or less of the said recesses, a stud carried by the lower face ,of the said stop. member 'and adapted to enter any one of the said recesses to fix the position ofthe said stop member, means carried by said casing for clamping said stop member againstsaid ledge and a projecting part movable with said stem and arranged to engage a'portion of said stop member whereby the angular movement of said stem is limited. i

3. In a device of the character described,
