3.. ENG, 015 NEW YGBK, N. Y., A COR- SUPEEVISOR'SZ' MECHANISM.
Application filed July To all whom it may concern:
Be it known that we, GHAnLns E. Ruin SHAW and Emma G. Hearst, both citizens of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Supervisory Mechanism, of which the following is a full clear, and exact description.
The invention whichconstitutes the subj cot-matter of this application relates to supervisory mechanism and has to do with access to a key contained in a receptacle located adjacent to a valve which constitutes a part of a sprin kler or other system. One of the important features of the invention consists in the provision of inexpensive and simplified mechanism for controlling access to the key or other instrument for producing a record upon the record'dial of a watchmans clock; that is to say, when the valve is open, as it nomally should be, access may be had to the watchmans key; but, it the valve is closed, or partly so, the key or other instrument for producing a record upon the record dial of a watchmans clock is not available. Each valve of the system is equipped with a receptacle so as to enable the watchman, when the valve is in normal position, to effect a record upon the record dial oi his clock which will indicate the time at which the station was visited. So long as these records are made at the required intervals, it is a sure indication that the valve at those particular times was open. But it a record is not effected, as will be apparent from the examination of the record dial, it is an indication that the valve at that particular time was not in normal position. If, however, it is a part of the watchmans duty to open the valve, or, more accurately speaking, to move it back to normal position, he can then, of course, make the necessary record on the record dial. In any event, the invention will have served its purpose.
Another feature of our invention consists in providing a device of the kind described whereby the key receptacle may be readily located at variable distances from the valve to which it is connected.
In the drawings:
Figure 1 illustrates a side view of the Specification of Letters Patent.
Patented Feb. 28, 1922.
Serial No. 2%,852.
1 parts of the valve and certain parts of key receptacle being illustrated in secon to show the interior construction.
F igure 2 is an enlar 'ed view of the key receptacle taken at right angles to the view illustrated in F 1, the lower part thereof being broken away to illustrate further details of construction. Figure 3 is a detail.
hei erring to the drawing in detail, the reference numeral 10 designates the water supply to the sprink er coming from any suitable pipe (not shown). Located in this supply is a valve 11 provided with ayoke l2, a threaded sleeve rotatably mounted in the yoke, a valve-stem 1 L screw-threaded to the sleeve, and a manipulating handwheel 1 fixed to the sleeve 13 and adapted to rotate the same in order to impart the longitudinal movement to the valve-stem 14 and the gate valve (not shown) attached thereto. The mechanism just described is old and well known and we make no claim thereto except as it constitutes or is an element of the combination.
The valve-s m 1% projects substantially above the manipulating-wheel l5 and suring this upwardly-projecting portion sleeve 16 screw-threaded or otherwise .ly secured to a base 17 which is in turn d, as by bolts 18, to the hand-wheel 15. This sleeve l6 is swivele-d, by means 01" the members 19 and 20, to one end of a rigid tubular member 2i, the other end of said member being connected by any suitable means to the receptaole-container 22.
The receptacle-comainer 22 may, of course, be of any configuration, but its longitudinal length is sullioient to enable a sub stantial reciprocation of the key-receptacle Which is contained therein. lVithin the tubular member 21 is contained a flexible liner, Q l, the length 01 which, as will be apparent from the drawing, is substantially the same as th length of the tubular member 21. l l ithin the liner 24: is a flexible and tubular wire coil which fits the liner rather snugly and within this coil is a flexible rod 26. The corresponding terminals of the shaft 25 and rod 26 are secured to each other, and in turn to the valve stem 14 and key receptacle 23, respectively. The object oi": the liner 2s: is to avoid any backnormally registering with the opening in the container, and means actuated by the movement of the valve from its normal position to impart a reciprocating movement to said receptacle to bring said openings out of registry.
6. In combination, a valve, a manually operable indication-producing means, means for rendering said first named means operable or inoperable, and means comprising a helical, longitudinally-movable member connecting said valve and second named means.
7. In combination, a valve, a manually operable indication-producing means, means for rendering said first named means operable or inoperable, means comprising a longitudinally-movable flexible member connecting said valve and second named means, and a spiral winding surrounding and movable with said member.
8. A supervisory mechanism as specified in claim 1 in which the flexible means is surrounded by a tubular member for impeding access to said means.
9. A supervisory mechanism as specified in claim 2 in which the flexible means is surrounded by a tubular member for impeding access to said means.
In testimony whereof We hereunto al'fix our signatures.
