JOHN T. OGQRMAN, on NEW YonK, N. Y.
teases rarest AUTOMATIC LOCK COCK.
Application filed June 24,
To all whom it may concern:
Be it known that T, J OHN T. OGORMAN, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Automatic Lock Cock, of which the following is a full, clear, and exact description.
This invention relates to safety devices for valves and particularly to an improved locking device for a gas cock or other form of valve adapted to be moved from an open to a closed position or the reverse.
The object of the invention is to provide a safety lock for cocks or valves which Wlll automatically become locked when moved to a closed position but which will permit the valves to be adjusted when in any other position.
Another object of the invention is to provide a lock for gas cocks wherein the lock may be readily manipulated by the same hand which opens and closes the cock.
In the accompanying drawing- Figure 1 is an elevation of a gascock with certain parts in section and disclosing an embodiment of the invention.
Figure 2 is a sectional View through Figure 1 approximately on. line 2-2.
Figure 3 is a side elevation of the structure shown in Figure 1.
Figure A is a view similar to Figure 2 but showing a cock which rotates for only a quarter of a turn.
' Referring to the accompanying drawlng by numerals, 1 indicates the body of a cock of a well known construction and the valve member or key therefor. A suitable lever 3 is secured to plug 2. The construction just described is old and well known and in the drawing a conventional gas cook has been shown though the invention could be applied to other forms of valves'if desired. A flange 1 is associated with the casing l and may be integral therewith or may be rigidly secured thereto, said flange having diametrically opposite apertures 5 and 6. These apertures are of such a size as to receive the locking pin or bolt '7 which locking pm or bolt is rounded at the lower end 8 andis provided with a head 9 at the upper end. This pin loosely fits in an aperture 10 in the arm 11 which arm is either integral with the plug 2 or rigidly secured thereto. This arm is preferably positioned dlrectly below 1922. Serial noQsvaeei.
the handle 3 and at such a height therefrom that when the bolt]? raised the head 9 will strike the handle 3 before the bolt leaves the aperture 10 ,so that it will be preventedfrom leaving said aperture until the, handle-3-is removed. .As the handle 3 is held in place by a suitable bolt structure of a well known kind, it will be evident that the bolt maybe removed whenever desired by removing the handle though ordinarily it is positively prevented from being removed. This prevents accidental loss of the locking bolt 7 and insures that it shall always be in position for operation.
As shown in Figures 1 and 2, the cock is illustrated as being closed. In case it should be desired to open the cock, a person may grasp the handle 3 and in doing so let some of the fingers engage the head 9 and raise the bolt 7 until it is disengaged from the flange 10. The handle 3 may then be swung around to the desired point. As soon as the bolt 7 is moved away from a point above the aperture 6 it may be released and will readily slide over the flange 4 when looking the valve. By reason of this characteristic, the valve maybe opened or closed to the desired extent freely but as soon as it is i moved to a fully closed position, the bolt 7 will drop into the aperture 6 or if .it is moved to a fully closed position on the opposite side it will drop into the aperture 5.
As shown in Figure 4, the valve is formed to open by a quarter of a turn and close by a reverse movement whereas in the construction shown in Figure 1 the valve may open by a quarter of a. turn and close by a reverse movement or it may open by a quarter of a turn and close by continuing the movement for a quarter of a turn so that in a half revolution of the plug 2, the valve will have been fully opened and then fully closed. The construction shown in Figure 4 is identical except that the flange 4; is substantially a quarter circle instead of half as shown in Figure 2 and, consequently, there is only one aperture for receiving the bolt 7.-
What I claim is l. The combination with a valve or cock having a casing, a plug and a handle for moving the plug to an open or closed position, of a flange secured to the casing having diametrically opposite apertures, an arm extending from said plug beneath said handle, and a bolt slidingly mounted in said arm, said bolt having a head for preventing the bolt from leaving the arm in one direction, said arm being positioned sutficiently near said handle to cause the head of said bolt to strike the handle when moved in the opposite direction a predetermined distance, said bolt being adapted to ride on said flange when the valve is open or partially open and to automatically drop into either of said apertures when the valve is moved to a closed position.
2. The combination with a valve having a stationary part and a movable part, a handle on the movable part for moving the same, a flange connected with the stationary part by an arm connected with the movable JOHN T. OGORMAN.
