Application filed February 25, 1909. berial No. 479,920.

To all whom it may concern:

Be it known that l, AARON J. TYLER, citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Curb -Bo2;es, of which the following is a specification.

This invention relates to curb boxes and has for its object to provide strong, durable, and thoroughly efiicient devices of this character, the construction and relative disposition of the several parts of which are such as to obviate the employment of the threaded connections for retaining the parts in as sembled position, which threads soon rust when exposed to the elements and render it difiicult if not impossible to obtain access to the interior of the box without mutilating or breaking the same.

A further object of the invention is to provide a curb box the cover of which is retained on the surface boX in such a manner as to prevent an unauthorized person from removing the same with a view to surreptitiously controlling the flow of the water in the supply pipe.

A further object of the invention is to provide a curb box capable of being readily adjusted to any depth of trench and in which provision is made for limiting the longitudinal movement of the stand-pipe, thereby to prevent the withdrawal of said stand-pipe from the casing and also to prevent the stand-pipe from wedging against the stop cock or valve and interfering with the proper operation of the latter.

A further object of the invention is to so position the fastening devices and surface box, that the former are entirely housed within the latter, the bottom of said surface box forming a closure for the stand pipe so as to prevent children or other mischievous persons from filling the stand-pipe with sticks, dirt, or other foreign matter, should the cover be accidentally left off.

A further object of the invention is to generally improve the construction of the curb box so as to render it easy to manufacture and assemble and thus reduce the cost of manufacture to a minimum.

Further objects will appear in the following description, it being understood that various changes in form, proportions, and minor details of construction may be resorted to within the scope of the appended claims, 7, V

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The improved curb boX comprises a valve casing or housing adapted to be embedded in the ground and preferably formed in two sections 5 and 6, the longitudinal edges of one of which are formed with laterally extending beads or flanges 7 which overlap the adjacent longitudinal edges of the mating section and form a closure at the juncture of said sections.

The lower end of each casing section is provided with an inwardly pro ecting portion 8 which registers with the inwardly projecting portion of the mating section thereby to form a closure for the bottom of the casing and thus prevent the ingress of sand, dirt, or other foreign matter to the valve or stop cock 9.

Extending laterally from the casing sections are oppositely disposed perforated lugs 10 which receive bolts or similar fastening devices, there being transversely alined openings 12 formed in the casing sections beneath the valve 9 for the reception of a single bolt or fastening device 13, which in connection with the bolts 11 serves to hold the casing sections in assembled position.

Slidably mounted for vertical movement within the casing is a stand-pipe 14; havingits upper end provided with laterally extending flanges 15 one of which is formed with slots 16 opening through the peripheral edge thereof, for the purpose hereinafter referred to.

Supported on the flanged end of the standpipe is the body portion of the surface box 17, said box being preferably cast or otherwise formed of metal and provided at its lower edge with a depending flange 18 which overlaps one of the flanges 15 of the stand-pipe when positioned thereon and forms a closure for theopen ends of the slots 16. The upper portion of the surface box is provided with a laterally extending flange 19 adapted to receive and support the downwardly turned edge 20 of a removable cover 21.

The central portion of the member 17 is provided with a depression or socket 22 which receives the head 23 of a pin or key 24, the height of the head 23 being such that the upper portion thereof will normally lie in a plane below the horizontal plane of the member 17.

The lower end of the pin 2st projects within a tubular member 25 and is rigidly combined therewith by a pin or fastening device 26 so that rotary movement imparted to one will cause a corresponding movement of the other.

Disposed within the tubular member 25 is a longitudinally disposed rod 27 of angular cross sectional formation, to the lower end of which is rigidly secured a cap piece 28. The cap piece 28 is provided with a key seat 29 for the reception of the T-head 30 of the valve 9, there being suitable recesses or depressions 31 formed in the opposite side walls of the key seat to accommodate the stem of the stop cock or valve when the key seat is positioned thereon thereby preventing the twisting or turning of one member relatively to the other and thus insure positive actuation of the valve when the key member 23 is operated.

As a means for permitting simultaneous movement of the rod 27 and the tubular member 25, there is provided a socket 32 in one end of which is seated the adjacent end of the tubular member 25, the opposite end of the socket 32 being formed with a longitudinal recess the walls of which conform to the annular formation of the rod 27 as best shown in Figs. 11 and 13 of the drawings.

The socket member 32 is rigidly combined with the tubular member 25 prefe ably by forming the socket member and tubular member with registering recesses, and subsequently driving a pin or similar fastening device 33 therethrough. Thus it will be seen that the tubular member 25 is free to move vertically of the rod 27 to permit the stand-pipe to be positioned in ditches of different depths, while the stand-pipe 14- is slidably mounted for vertical movement in the casing or housing 5 and carries to surface box, the stand-pipe and its associated parts being locked in adjusted position by manipulating the clamping bolts 1.1. If desired, however, any other suitable means may be employed for clamping the parts together in fixed position after the adjustment of the same has been effected.

Secured to or formed integral with the lower end of the stand-pipe 14 is a late ally extending shoulder 3-1- which coacts with suitable projections on the adjacent casing sections and serves to prevent the with drawal of the stand-pipe from the casing, there being a simil r shoulder 35 formed on the upper portion of said stand-pipe and ar ranged to bear against the adjacent portion of the valve casing for limiting the downward movement of the stand prevent said stand pipe from coming in eon tact with and wedging or otherwise in1pairing the operation of the valve 9.

One of the important features of the present invention is the means employed for retaining the surface box in position nu the stand-pipe, and for preventing an unauthorized person from removing the cover of the surface box with a view to surre1; titiously operating the key 21, thus to cut oil the flow of water in the supply pipe 30. Such a result is accomplished by forming the body portion'17 of the surface box with openings 37 for the reception of threaded bolts 38 the shanks of which are extended through the openings 16 for enga ement with clamping nuts 39, the heads of the bolts being set in sockets or recesses 10 formed in the standpipe for the reception of the same, as best shown in Fig. 1 of the drawings.

@ne of the fastening devices or bolts 38 is extended through an opening 4-1 in the cover 21 for engagement with a clamping nut 42, the latter being seated in a recess 13 in said cover so that the upper )OltlOll of the nut will be disposed substanti: ly flush with or slightly below the horizontal plane of the cover 21, and thus present a smooth surface at ground line.

itttention is here called to the fact that the fastening devices 38 are entirely housed by the cover 21 so that the said fastening devices are protected from the elements and thus prevented from rusting. It will also be noted that the flange 44 of the nut 12 pipe, and thus llO aaepoi forms in eflect a closure for the opening ll in the cover so as to prevent the entrance of moisture or water to the interior of the surface box.

The head 23 of the pin 24 is preferably inclined or tapered for engagement with a specially constructed key, the top of the head 23 being provided with a transverse rib 45 adapted to register with suitable index characters 46, in the present instance, the letter 0 so that the operator upon removing the cover 21 may readily ascertain whether the flow of water is turned off or on. By securing the cover of the surface box on the stand-pipe in. the manner described, the en'iployment of threads which have a tendency to rust is obviated, and at the same time the cost of manufacture is reduced to a minimum. It will also be noted, that by making the opposite ends of the casing 5 at the valve 9 relatively thin and substantially parallel with each other, a flattened surface 46 is presented for let-- tering or for'displaying any advertisements thereon.
