CUT-OFF SOCKET.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed May 11, 1905. Serial No. 260,031.

To all whom it may concern.-

Be it known that I, DANIEL HOWARD HAY- WOOD, a citizen of the United States of America, and a resident of the city, county, and

State of New York, have invented certain new and useful Improvements in Cut-Ofi' Sockets, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in cut-ofi sockets of the character disclosed and claimed in a copending application by Olaf Saugstad, filed March 18, 1905, Serial No. 250,754. In such applicationa cut-off socket is shown and described adapted for the reception of a thermostatic regulator when used in connection with hot-water tanks. The cut-off socket has a valve device by which communication can be opened or closed between the water in the tank and the interior of the socket in which is contained the thermostatic portion of the regulator. By this means the regulator may be removed at will without it being necessary to first drain the tank and when replaced may be directly immersed in fluid circulating through the tank.

The present invention includes means for automatically opening and closing such communication upon insertion or withdrawal of the regulater, whereby the mere act of inserting the regulator will open circulation from within the tank to within the socket and the mere act of removing the regulator will cause such circulation to cease. When the Valve mechanism is thus automatically controlled, the danger of removing the regulator without first turning off the water or of forgetting to turn on the water after the regulator has been inserted is entirely eliminated, as will be well understood, and, further, no instructions will be required to the workmen in removing and replacing the regulator, as all conditions are automatically taken care of.

My form of the device further lends itself to the multiplication of ports without much additional complication, whereby free circulation when the valve is open is insured and such free circulation insured in any position of the socket.

My invention further consists in certain novel details of construction and combination of parts, as will be hereinafter more fully pointed out.

In order that my invention may be more fully understood, I will now proceed to describe several forms of cut-off sockets embodying same and will then point out the novel features in claims.

In the drawings, Figure 1 is a view in central longitudinal section through a cut-0E socket embodying my invention,showing same in position in a tank and showing also in dotted lines a thermostatic regulator mounted therein. Fig. 2 is a View in central transverse section through the socket, the plane of section being taken substantially on the line 2 2 of Fig. 1. Fig. 3 is a view in central transverse section through the socket, the plane of section being taken substantially on the line 3 3 of Fig. 1. Fig. 4: is a fragmentary view in central longitudinal section, showing a slightly-modified structure. Fig. 5 is an end view of the same. Fig. 6 is a fragmentary view in central longitudinal section of a further-modified structure.

Referring first of all to the form shown in Fig. 1, the socket comprises a shell 1 and a tubular extension 2, closed at the end by a cap 3 or equivalent means. The shell is provided with a screw-threaded portion 4:, by which it may be screwed into a corresponding internally-screw-threaded opening in the wall of a tank, boiler, or the like. 5 designates the tank, a portion of which is shown in the drawings. At its outer end the shell 1 is provided with an internally-screw-threaded portion 6, arranged to receive a thermostatic regulator 29, here shown in dotted lines as in operative position. The length of the shell portion 1 may vary as desired. It may be quite short, if preferred; but it is convenient to make it several inches in length, because the tank is usually lagged with asbestos or other covering, and in such case a socket so made brings the head of the regulator out to a convenient position beyond the lagging, as will be readily understood. A valve-casing 7 is fitted to the outer end of the socket-shell 1, being here shown as screwed into the screw-threaded portion 6 and having a flange 8, the end of which is accurately fitted to the shell by means of a ground joint 9 to prevent leakage. Between the flange and the body of the socket-shell is formed an annular channel 10, and connecting with this annular channel 10 are a series of ports or passages 11, affording communication with the interior of the tank. An annular valve 12 is fitted to a valve-seat 13, formed at the rear end of the valve-casing 7. The said valve opens toward the channels 11 and closes in the opposite direction, whereby pressure of water within the tank will tend to keep the valve closed. A light spring 14 may be em ployed, if desired, to keep the valve normally in its seat. An operating-ring 15 is fitted to a suitable annular channel in the valve-casing 7 and is connected with the valve 14: by a plurality of stems 16, which pass freely through longitudinal openings 17. The operatingring 15 projects outwardly beyond the outer face 18 of the valve-casing and in the path of the regulator to be inserted. When the regulator is inserted, it will engage the ring 15, and forcing same inward toward the tank will open the valve 12, thereby opening communication from the tank through the ports or passages 11 to the longitudinal opening 17. Transverse openings 19 allow communication from the openings 17 to the interior of the socket, whereby free circulation is established between the interior of the socket and the interior of the tank whenever thevalve l2is opened. Removal of the regulator will cause the valve 12 to automatically close, the pressure of the water from the tank being sufiicient to effect this directly the abutment which engages the ring 15 is removed. The spring 14:, if employed, will further assist in this movement.

Preferably I provide a plurality (three or more) of the channels 11 around the socketbody, as shown in Fig. 3, because when so arranged the angular position of the socket with respect to the tank is immaterial?l. a, it is immaterial in screwing the socket into place as to at what point angularly the socket is finally brought to rest.

In Figs. Land 5 I have shown a slight modification in which a plurality of independent valve devices 20 are secured'in position around the central opening of the socket, the valvestems 21 protruding therefrom in the path of the regulator. Each valve device is preferably screwed into an independent recess 22, communicating with a corresponding port or passage 11. A plurality of valve devices are preferably employed, conveniently three, as shown, so as to insure circulation in any position of the socket.

In Fig. 6 a still further modification is shown, in which the socket body or shell is formed in two parts 23 24, the portion 23 constituting the valve-casing. In this instance I have shown a plurality of valves 25 fitted to corresponding valve-seats 26 and with their stems 27 engaging an operating-ring 28, arranged in the path of the regulator when in operative position.

In all forms of the device it will be seen that the following principle remains the same: The screwing of the regulator into place automatically operates the valve mechanism to open communication between the interior of the tank and the interior of the socket,whereby the thermostatic portion of the regulator is immersed in the tank fluid as fully and completely as if the socket were not present, while the unscrewing of the regulator to remove same causes the valve mechanism to close, so as to out 011 such communication, whereby escape of water other than the small quantity locked up in the socket itself will be prevented. It will also be seen that the device is inexpensive to manufacture and comprising but few parts will not be liable to get out of order.

What I claim is 1. In a cut-off socket, the combination with a socket member arranged to removably support a regulator, of means for controlling admission of fluid to the socket, operated by the insertion and removal of the regulator.

2. Acut-offsocketcomprisingasocket member having means for securing same to a tank, and means for removably receiving a regulator therein, and means operated by the insertion and removal of the regulator for controlling admission of fluid to the socket from the tank.

3. A cut-off socket having a portion adapted to enter a tank, and provided with means for securing it to the tank, said socket adapted and arranged to removably support a thermostatic device, and provided with means operated by the insertion and removal of the thermostatic device for controlling admission to the socket of fluid from the tank.

1. A cut-off socket comprising a shell adapted to be secured to the wall of a tank, and a tube adapted to extend inward Within the tank, said socket adapted and arranged to removably support a regulator, and provided with means operated by the insertion and removal of the regulator for controlling admission to the socket of fluid from the tank.

5. A cut-off socket comprising ashell adapted to be secured to the wall of a tank, and a tube adapted to extend therefrom inward within the tank when in position therein, said shell having an internally-screw-threaded portion adapted for engagement with the correspondingly-screwthreaded portion of the temperature-regulator; and means operated by the insertion and removal of the temperature-regulator for controlling admission to the socket of fluid from the tank.

6. The combination with a tank and a thermostatic device extending therein, of a cut-ofi? socket surrounding the portion of the thermostatic device in the tank, and means operated by the insertion and removal of the thermostatic device for controlling admission of fluid to the socket from the tank.

7. The combination with a tank of a socket extending within same, a thermostatic device removably fitted to said socket, and means op- IIO in said casing arranged to control admission of fluid to within the socket, and an operating member for said valve arranged to be engaged by said thermostatic device while it is being inserted.

10. In a cut-oiI socket, the combination with a socket member or shell arranged to remov- 2O ably support a-regulator, said shell provided with a plurality of circulating-passages, of valve mechanism controlling said passages, and operated by the insertion and removal of the said regulator.
