Specification of Letters Patent.

Patented July 29,1913.

Application filed April 12, 1913. Serial No. 760,606.

To all whom it may concern:

Be it known that I, Vroron LEE EMnnsoN, a citizen of the United States, residing at Alexandria, State of Virgima, have invented certain new and useful Improvements 1 n FaucetValves, of which the following 1s a specification.

My invention relates to a faucet valve which is especially adapted for use wlth receptacles, the interior of which are pltched or covered with a similar substance before being filled. The operation of such valves has been found to be seriously interfered with by the pitch stopping up the cavities or ports of the valve and getting between the moving parts thereof, thereby subjecting them to undue wear and rendering the valve subject to leakage.

Various means have been proposed to clear the seat and the valve from the pitch which adheres thereto when the receptacle is coated, but have failed in their purpose due to the fact that the broken pitch is either left on the seat or carried by the moving parts into proximity with the outlet passages and is drawn into the same by the motion of the fluid, thereby clogging the valve and rendering the same inoperative. Another difficulty to which such valves have been subjected is that the material out of which they have been made, especially that portion which constitutes the seat and moving member in contact therewith, has been unable to withstand the corrosive action of the contents of the receptacle and the heat caused by the pitching process or to prevent the seats from drying out and shrinking when not in use.

An object of my invention is to overcome the difficulties which are caused by pitch interfering with the operation of the valve, as above set forth, by adopting a construction in which the seat is protected from the pitch during the pitching process, and also by forming the valve seat upon a projecting neck of such shape that that portion of the controlling member, which is exposed in the opening movement, is moved out of contact with the body by the opening movement, thereby avoiding the cutting of the seats by deposits left on the valve body and preventing the seat and controlling member from being damaged or gummed by the scraping off of the pitch, when the valve is opened, there being no possibility of the pitch that is usually scraped 0d the body of the valves of the usual construction being carried over the ports by the moving member of the valve and carried into the body thereof by the flow of the liquid or stopping up or obstructing the passages or ports.

Another object is to provide a construc tion which will break the pitch on a line with the face of the valve seat, by producing a shearing cut when the valve is opened.

A further object is to provide a valve which shall be free from cutting due to the opening and closing of the valve as in the case where seats are employed having the same density.

A further object is to make the valve selfadjusting and to protect the adjustable parts from contact with the contents of the receptacle or with the pitch.

A further object is to adapt my valve to receive a seal in the outward face that will be flush with the surface or face of the valve body.

In the accompanying drawings which illustrate a preferred and modified embodyment of my invention and in which like reference numerals indicate similar parts; F ig ure 1 is a cross-sectional elevation through the center of my device said section being taken through the widest part of the neck, showing the passages. Fig. 2 is a cross-sectional elevation through the center of my device, taken through the narrow portion of the neck. Figs. 3 and 4 are elevations, partly in section, showing the controlling member in closed and slightly opened positions, respectively, indicating the shearing action on the pitch, When said controlling member is moved as indicated. Figs. and 6 are perspective views of my device showing the controlling member in closed and open position, respectively. Fig. 7 is a detailed view showing the spindle of the controlling member. Fig. 8 is a modification of my device in perspective. Fig. 9 is a detail view of the controlling member showing the projecting stop. Fig. 10 is a plan view of the seat on the projecting neck of the modification. showing the groove for the stop. 1

Referring to Fig. 1 the numeral 1 indicates a threaded base. 2 indicates a projecting neck, which in the embodiment shown. is illustrated as integral with the base, but which may be separate therefrom if so desired. The projecting neck is herein shown with a wide and narrow section which is fashioned by forming cutaway portions or recesses in the body as shown. In the embodiment shown, I have chosen to form the wide section co-extensive with the body, the narrow section presenting concave faces, but the neck may take various forms within the scope of my invention. Upon the upper end of the neck is formed the seat 3 with which a member 4: cooperates to control a passage or passages 5 which extend through the body 1 and neck 2. That portion of the controlling member which is in contact wit-h the seat 8 is herein shown as co-extensive therewith. Said controlling member is formed with deep vertical section and has a tube or housing 6 projecting therefrom and formed integral therewith. The tube 6 is threaded at its outer extremity to receive a cap 7. This construction gives the controlling member great stiftness and prevents it springing from the seat 3 when subjected to the stress of compression. It will be noted that the integral tubular extension is necessary in order that the controlling member be given the needed strength. It will be readily seen that the controlling member is non-circular in form, and is cut away and centrally bored. At this critical point the integral tubular extension is placed, and forms a bridge of metal to resist the strains which without it would be dangerous to the rigidity of the structure. In this form of my invention I have chosen to make that portion of the controlling member, which comes in contact with the seat 3, of a substance which has a greater density than the material of which the seat 3 is formed, as shown at a. This is done in order to prevent the cutting action between the controlling member and the seat 3. It is obvious that I may form either of the contacting surfaces of a substance of the character described or that I may form either the controlling member or the body of such a substance. The substance which is of the greater density may be composed of Monel metal, porcelain, glass, agate, or the like. The controlling member is held against the seat 3 by the spindle 8, which passes through the bore 9 in the body. The spindle 8 is provided with a member 10 cont-acting with a seat in the body, and forming a ball and socket connection therewith. The bore 9 has a diameter slightly in excess of the diameter of the spindle S, in order that the spindle may have a certain play to allow for the automatic adjustment of the controlling member. This ball and socket connection permits the controlling member to antomatically adjust itself to any irregularities of the controlling member 4 or seat 3 should they vary from right angles from the axial line. Above the member 10 the spindle is provided with a flattened portion 11 which is adapted to fit in a bore of similar shape in the cont-rolling member 4 so that the spindle is prevented from rotary motion with respect to the controlling member. Above the flattened portion the spindle has a threaded portion extending into the tubular extension of the controlling member. On this threaded extension is mounted a spring 12 which is held between the washer, which is next to the controlling member and adjusting nuts 18. By adjusting said nuts the tension between the controlling member and the seat 3 may be varied at will. The lower extremity of said spindle is provided with a flattened portion which is adapted to receive a key for turning the same. It will be noted that the extended neck 2 is formed of deep section, through which the spindle and passages pass, so as to present a section of great strength to the controlling member. This construction prevents the springing of the valve seat on the valve body, as is experienced in flat disk-shaped seats. The base is formed interiorly with two connecting chambers 14 and 15 which are separated by a web 16 which gives great strength to the base to resist distortion when being forced into the receptacle. In the walls of the chamber 15 is formed an interrupted groove of the bayonet type adapted for the reception of lugs on the key. The interior of my valve is formed with filleted corners so that it will be hygienic and easy to clean. The chambers are open and free from obstruction, making an easy and direct passage for the fluid. I11 the base 1, I form a recess 18, which is adapted to receive a seal, which protects the interior of the valve from being filled with foreign substances, after the filling of the receptacle. This feature is very desirable, in that it prevents the fluid, which is usually a beverage, from being contaminated with foreign and injurious substances.

In the modification shown in Figs. 8, 9 and 10 I have provided a controlling member with a stop 19, which is adapted to move in a groove 20 formed in the seat 3 on the neck 2. This groove and stop serve to check the controlling member at open and closed positions, thereby assuring the proper manipulation of the controlling member. The groove is of such extent that the controlling member is not allowed to uncover it, thereby preventing the groove from being clogged by pitch or other substances.

Instead of the usual method of. tinning the surfaces of the valve, which soon wears oft, I form my valve of a substance which has a resistance to the corrosive action of the material to be handled, as a composition of tin, copper, zinc and iron.

It will thus be seen that I combine in my valve many desirable features, and have produced an article which has, in actual test, proven to be highly efficacious in producing the results above set forth.
