EDWARD J. CHADBOURNE, OF WAKEFIELD, MASSACHUSETTS.

STOP-COCK BOX.

SPECIFICATION forming part of Letters Patent No. 613,652, dated November 1, 1896.

Application filed Marell 14,1898. Serial No, 673,841. (No model.)

To all whom it may concern:

Be it known that I, Edward James Chadbourne, a citizen of the United States, residing in Wakefield, county of Middlesex, and 5 State of Massachusetts, have invented a new and useful Service-Cock Box, of which the following specification, including the accompanying drawings, bearing letters of reference herein referred to, is a full and exact io description.

My invention relates to improvements in service-cock boxes—in other words, to the means or device employed in connection with water-supply distribution to protect and give 15 access to the stop-cocks that are used underground to let on and shut off the supply of water to and from the consumei—my objects being to insure the most convenient accessibility with the operator’s key to the stop-cock, 2t> to protect said cock, to avoid danger of derangement by frost and temperature changes to the cock, and especially to simplify and render the device as inexpensive as possible.

I attain the objects noted by means of the device illustrated and hereinafter more fully described.

Referring to the drawings, Figure 1 is an elevation including the box, a section of the supply-pipe, and the stop-cock; Fig. 2, an ele30 yation showing key; and Fig. 3 is a corresponding sectional elevation taken at right angles to Fig. 1,the base d being omitted. Fig. 4 is an under view of cap a. Fig. 5 is a side elevation of same and showing lock-nut Z, screw k, and 33 pin n. Fig. 6 is a plan without the cap. Fig.

is a plan of base d and parts of supply-pipe. Fig. 8 is a side elevation of base d corresponding to Fig. 1. Fig. 9 is a sectional elevation of same parts as shown in Figs. 7 and 8.

Like letters refer to the same or corresponding parts in all the figures.

The device consists of four main parts— viz., the cap a, including the lock-nut Z, its screw k, and pin n, the body &amp;, the lower 45 body c, and the base d. Beginning with the base, its construction may be understood by reference to Figs. 1, 9, 8,’ and 7. This base is a simple casting, requiring no fitting, of pot form, having drainage-opening d' in the 50 bottom, which also admits the bottom end of cock e. It is provided with slots in the rim, suitable to receive the service-pipe, which slots extend downward from its top and then around the circle horizontally something more than the semidiameter of the service- 55 pipe. These slots are opposed to each other and extend around the circle in one direction. Thus the base-pot may be lifted from beneath the pipe entering the slots and then on being partially rotated locks itself upon the pipe, as 60 seen in Figs. 7 and 8, where it will hang upon the pipe or may be supported from beneath by filling under it. After this the lower body c, which is. large enough at the lower end to shut over it and is provided with upwardly- 65 extending slots, similar to the downwardly-extending ones in the base, is then dropped on, embracing both the base and the pipe f, and on being partially rotated in the opposite direction is thereby locked down upon the pipe, 70 and consequently over and around the base, as seen in Fig. 1.

The locking-slots in the lower body and those in the base extend in opposite directions around the circle as they stand, although, of 75 course, if one were inverted the slots would then be seen to extend around in the same direction. These slots may leave the part overlapping the pipe a little hooking, as may be seen in Figs. 1 and 8. . 8&amp;

The body b is made larger than the upper portion of the lower body c, so that it slips Over it like a sleeve, more or less, according to the depth the pipe is laid from the surface of the ground, pavement, or sidewalk. 85

The top end of the body has an outer bead or rim for strength and an inner one having slots, as seen in Fig. 6 and dotted lines Fig. 1. These allow the lock-nut Z, connected to the cap a, to drop through. The inner rim has 90 also the recesses x and stop j. (Shown in dotted lines, Fig. 6, and in Fig. 3.)

The cap a has a drooping rim in which are formed the slots m, in which the lock-nut is guided and turned about with the cap a. 95

A screw k has a seat or bearing in a depression in the top of the cap and, passing through the cap, is threaded to fit the locknut, and a pin n through it keeps the nut from accidentally screwing off. The top end 10ό of this screw is made in any form to fit and be operated by the operator’s key.

When it is required to put the cap on, it is dropped on, the inner rim entering the body613,652 top, the lock-bolt dropping through the slots p, (see Fig. 6,) after which the cap is turned until the lock-nut comes to the stops.;’ or under the adjacent recesses x, (see Fig. 3,) when 5 on turning the screw the lock-nut grips the inner rim of the body and the cap is fastened. When it is required to take the cap off, the reverse movement is given the screw until the nut drops clear of the recesses x, when the cap io may be turned till the lock-nut comes to slots p and is drawn up through them and the cap lifted. When the cap is off, the wrench or key g may be passed down to the cock e, and, gripping its plug h with its jaws i, the plug 15 is thereby easily turned for letting on or shutting off the water, and the whole device may also be used iu similar cases for gas aud other underground stop-cocks.

The parts may be simple iron castings ex20 cept the screw k, nut I, and pin n, which are preferably of non-corrosive or non-oxidizable material.

The arrow in Fig. 7 indicates the direction the base is turned when locking it to the pipe. 25 The arrow in Fig. 6 indicates the direction the screw is turned when locking the cap. It also indicates the direction the lower body is turned when locking it to the pipe and so inclosing the base already locked thereto.
