VALVE.

SPECIFICATION forming part of Letters Patent No. 637,161, dated November 14, 1899.

Application filed January 23 1 8 9 9.

To all whom it may concern.-

Be it known that I, JOHN H. RING, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to steam, gas, or water valves, and the purpose of the same is to provide a self-adjusting non-leaking valve of the character set forth in such a manner as to simplify and cheapen the construction and increase the efficiency of operation.

The invention consists in the provision of a construction whereby when the plug or parts coacting therewith become worn out or incapacitated in any manner the same can be readily adjusted, removed, and replaced by others without necessitating the disconnection of the valve-casing from the pipes to 'which it is secured, and also requiring but one quarter or less of a full turn of the device for operating the valve-stem in order to open or close the valve, and, further, to so arrange the valve as to dispense with packing of any character and utilize the positive operation of incidental attachments to always hold the plug to its seat and maintain a uniformity of operation.

The invention further consists of the general and detail construction, arrangement, and combination of parts, as hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of the improved valve. Fig. 2 is a transverse vertical central section of the same. Fig. 3 is a detail perspective viewof the valve-plug and a part of the stem. Fig. 4 is a horizontal section, slightly enlarged, on the line w m, Fig. 2. Fig. 5 is a detail sectional view of a slight modification. Fig. 6 is a vertical longitudinal sectional View of the device embodying a modification. Fig. 7 is a top plan view of the device shown by Fig. 6, showing the stem cut off. Fig. 8 is a horizontal section on line a; 00, Fig. 6. Fig. 9 is a similar view on the line 212/ Referring to the drawings, wherein similar Serial No. 703,139. (No model.)

numerals are utilized to indicate correspond ing parts in the several views and now particularly referring to Figs. 1, 2, 3, 4, and 5, the numeral 1 designates the shell or valvecasing, having threaded

openings

2 and 3 in a part thereof and horizontally arranged in similarly-positioned members of the casing for the reception of inlet and outlet pipes or an inlet-pipe and dispensing-spout, and with which also may be employed a waste-outlet. (Not shown, but fully understood in the art.) Intermediate of the members containing the threaded

openings

2 and 3 and rising Verticallyis a hollow head 4, having upper internal screw-threads 5 in a portion of the same and a circumferential shoulder 6 below the threads. The opening in or the hollow portion of the head 4 is continuous with a lower frusto-conical opening 7, intermediate the members containing the screw-threaded

openings

2 and 3 and continuing downwardly into a lower drop 8. The wall of the opening 7 forms a seat for an elongated plug-valve 9, having a way 10 cut therethrough and an upper beveled head 11, from the center of which a stem 12 rises and is adapted to receive at its upper end a lever, handle, or wheel 13. Between the seat for the said valve and the inner terminations of the screw-threaded

openings

2 and 3 slotted partitions 14 are positioned, and the slots thereof are of the same dimension as the way 10 of said plug, the latter being alined with the slots in the partitions when the valve is opened to form a straight and unimpeded passage through the same. The lower reduced end of the plug-valve 9 bears upon the upper in nor surface of the drop 8, and to accurately adjust said valve in opening and closing the same the lever end thereof has a slot 15 extending entirely therethrough and fits over and coacts with a vertical stop-pin 16, rising from said surface of the drop and eccentrically positioned, as clearly shown in Fig. 4. The said pin 16 stands in such relation to the lower end of the plug-valve as to positively engage corresponding portions of the opposite Walls of the slot 15, and the primary adjustment is such also that it will be im possible to turn the valve 9 beyond a predetermined point in opening or closing the same and requiring but a quarter-revolution or less of the lever, handle, or wheel 13 to accomplish either result.

As clearly shown by Figs. 1 and 2, the opening 17 in the head EL is larger than the opening 7 to receive the plug-valve, and the wall thereof is straight, terminating with equal diameter at the shoulder 6. The upper screwthreads 5 of the head 4: surround the inner part of a larger opening or seat in said head, which is adapted to receive a cap 18, having a flange 19 to bear on the upper end of said head, screw-threads 20 to articulate with the threads 5, and a circumferential shoulder 21 to rest on the shoulder 6. The outer face of the flange 19 is adapted to be formed with angular faces for engagement of a wrench or analogous device to remove or apply the said cap,and the stem 12 extends centrally through the cap.

As shown by Figs. 1 and 2, the cap 18 has an integrallydepending sleeve 22, which snugly engages the opening 17 of the head 4, and has a lower reduced edge 23 to bear on the periphery of the conical head 11 of the plug-valve 9. By the formation of the reduced lower end 23 of the sleeve frictional contact on the head of the valve is materially diminished, and at the same time means for accurately holding said valve in its seat are provided. Vithin the said sleeve 22 and surrounding the stem 12 a spring 21 is mounted and bears on the head 11 of the valve 9. The purpose of this spring is to institute a cushion-pressure on, the valve and insure an accurate registration of the way thereof at all times with the slotted partitions 14': irrespective of the function of the sleeve 22.

The cap 18 and the sleeve 22, as shown by Fig. 5, maybe made in two parts, and in this instance said cap holds the sleeve to its place by an overpressure, as will be readily seen. By the use of the cap and sleeve in either form and the elongated construction of the valve-plug a perfectly steam, water, or gas tight fitting is produced without the employment of the usual packing, and in addition the valve is held properly to its seat. By unscrewing the head 18 suffioiently and drawing upwardly on the stem 12 the plug, spring, head, and sleeve can be simultaneously withdrawn from the casing of the valve without disconnecting the latter. This is especially convenient in readjusting or correcting any irregularities that may become apparent in the valve, and said parts may be as readily repositioned in the casing after repair or other similar parts substituted therefor. This ready withdrawal and insertion of the parts provides also for conveniently cleaning the valve as an entirety or removing any obstructing material.

The pin 16 in the drop 8 is shown in a position to accommodate a certain movement of the valve; but it will be understood that a reversal of said pin might be made to obtain an opposite movement and secure the desired result.

To hold the cap 18 against accidental movement after the device is properly set or adjusted, screws 25 are employed andremovably extended into the flange 20. In separating the parts these screws are first detached. These screws can also be used from time to time, if need be, to firmly hold the valve by first turning the cap into the casing and after securing it as before.

In Figs. 6, 7, 8, and 9 a modification of the valve is shown and adapting the same general principles to faucets. In this instance the casing 26 has but one threaded opening 27, and the bottom of said casing has in addition a vertical opening 28 therethrough. In the side of the casing opposite the location of the threaded opening 27 a horizontal slotway 29 is formed, and in this instance also the cap 30 and sleeve 31 are the same as in the structure previously described. Screws 32 are employed to prevent the cap from having self-loosening movement and serve a similar purpose as regards adjustment, as heretofore indicated. In this instance a spring 33 is confined by the sleeve 31 and surrounds the stem 34 of the plug-valve 35. The opposite terminating ends 36 and 37 of said spring are held in en gagement,respectively,with the cap 30 and top of said valve, and the valve is by this means automatically returned to normal position in addition to the function of said spring, as explained in relation to former construction. Near the lower end of the valve a pin 38 is located and projects outwardly in a horizontal plane and works in the slotway 29 to limit the movement of said plug. In the lower part of the plug a way 39 is formed and comprises an upper horizontal limb 40 and a vertical limb il. lVhen the horizontal limb 40 is turned in alinement with the threaded opening 27, water or other liquid to be dispensed passes down through the vertical limb 4:1 and out through the vertical opening 28, and after a preferred or sufficient quantity has been drawn the valve-stem is released and the valve automatically closed. The sleeve in this form of device also takes the place of packing and insures a firm seating of the valve subject to adjustment, and also by the general construction a convenient and eifective dispensing-faucet is provided.

Having thus described the invention, what is claimed as new is-- 1. In a valve, the combination of a casing having a valve-seat and a hollow head, a plug- Valve rotatable in said seat and having a way therethrough and provided with a stem, a cap applied to and closing the upper end of the hollow head and having' the valve-stem passing therethrough, a non-rotatable sleeve located in the hollow head and adapted to bear on the upper end of the valve and interposed between it and the cap, a spring wholly inclosed within the sleeve and surrounding the stem and confined between the cap and Valve, and a pin projecting inward from the casing and entering a cut-away portion of the valve to limit its rotative movement, substantially as described.

' 2. In a valve, the combination of a casing having a valve-seat with alower projection eX- tending eccentrically thereinto, a plug-valve removably fitted in said seat and having a stem at the upper enlarged end and a slot extending entirely through the lower end and having opposite parallel walls, said slot receiving the lower projection which is adapted to contact with the parallel walls of the same,

a cap having an integral non-rotatable pend-
