DANIEL H. SHERMAN, OF BUFFALO, NEWV'YORK.
STOP-VALVE BOX FOR WATER OR OTHER MAIN AND SERVICE PIPES.
SPECIFICATION forming part of Letters Patent No. 313,541, dated March 10, 1885.
' Application filed July 5, 1884. (No model.
T 0 all whom it may concern.-
Be it known that I, DANIEL H. SHERMAN, of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Stop-Valve Boxes for Water or other Main or Service Pipes, which improvenient is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a plan and elevation of my stopvalve box. Fig. 2 is a section and bottom plan of the cover for the valve-box, and Fig.3 is
' aplan and elevation of the adjustable tube for the stop-valve box.
The object of my invention is to furnish an adjustable box for the protection of water, gas, or other pipe valves when placed below the surface of the ground, and of obtaining access to the valve by means of the ordinary valve-key used for operating the stop-valve.
In the drawings, A is the lower or stand pipe. of the box, with a straight or conical shape foot, or globe or bell shape, as circumstances require, the object being to provide a form of tube that cannot be removed'from the ground without excavation. Upon the inside of this stand-pipe is an inclined plane or wedge shap'e rib, a, for a bearing-surface for the cams b on the adjustable tube B.
The operation of adjusting the tube B in the stand-pipe A to the height of thesurface of the ground is performed by placing the tubeB to the exact height required, and turning the tube B in either direction until the cam b is in contact with the rib a, which secures the tube in the desired position.
The cams b may be formed by making the tube B of the required shape.
The cover 0, for protecting the stop-valve, is provided upon its lower side with a flange, 6, extending around the cover, and is provided with notches c for the reception of the corrugated projections or ears 6 upon the tube B.
The operation of locking the cover 0 to the tube B is by turning the cover with the valvekey on the knob g in the direction to bring the ear 6 in contact with the longitudinallycorrugated inclined surface d upon the flange e, and lockingby the friction of the corrugated surfaces e at and the surface f, and of unlocking by turning in a reverse direction. The surfaces 6 and d are longitudinally corrugated to increase their surface and friction in locking.
I do not claim as new the flanged cover 0 and inclined surface d, in combination with the ears 6 on the tube B, as I am aware that the same have been before described for a similar purpose.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination of the stand-pipe A, provided with the rib a, with the adjustable tube B, provided with the cams b, all arranged and operating substantially as and for the purpose v shown and described.
DANIEL H. SHERMAN.
