SAFETY LOCK STOP Invenipr Jaw, a Wi'Me m A itomey June 10, 1930. J, 'W H I 1,762,371

SAFETY LOCK STOP Filed July 20, 1929 Z Sheets-Sheet 2 Inventor By 2mm Aiiomy Patented June 10, 1930 UNITED STATES JOHN GHRISTEN WILHELM, OF BARTLESVILLE, OKLAHOMA SAFETY-LOCK STOP Application filed July 20, 1929. Serial No. 379,800.

The present invention relates to safety lock for stop-cocks and has three direct purposes. The first is its ability of preventing anyone from stealing oil through a non-lockable stop cock. The second is the prevention of its loss through the removal of the core from the seat which is caused by free using or by people meddling with it. This would be a heavy loss to any oil company.

The third purpose is that it compels the gauger who is in charge of runn ng thls oil, to go to the back of the tank, as he is supposed to do by orders of practically all pipe line companies to see that no oil is being lost after the tank is turned into their line by the gauger, as each time the tank is turned on this stopcock, in the rear of the tank, must be locked.

A further important object of the invention resides in the provision of a device of this nature which is simple in its construction, 1nexpensive to manufacture, easy to mount 1n place, and thoroughly efficient and reliable in use.

With the above and numerous other objects in view as willappear as the description proceeds,.the invention resides in certain novel features of construction, and in the COIIlblDflw tion and arrangement of parts as will be here inafter more fully described and claimed.

In the drawing: Figure 1 is a side elevation of the device showing the same in place on a stop-cock.

Figure 2 is an end view of the stop-cock with the attachment thereon,

Figure 3 is a top plan view thereof, Figure L is a sectional view taken substantially on the line 4-4 of Figure 2, and

Figure 5 is a fragmentary section taken substantially on the line 5-5 of Figure 1.

Referring to the drawing in detail it will be seen that the letter S denotes a stop-cock or valve which includes the usual core C.

The numeral 5 denotes a cup shaped memher adapted to encase the lower extremity of the core C adjacent portions of the casing of the stop-cock S and other accessories and this cup shaped member 5 is provided w1th upwardly directed oppositely disposed spaced parallel coextensive elongated plates 6.

An inverted cup shaped cap 7 adapted to cheese the upper end of the core C is provided on its top with a channel or groove 8 in which rests a pin 9 extending through openings in the upper ends of the plate 6 and on one end 58 having a head 10 and at the other end having an opening for receiving a lock 11. ()bviously, therefore, to operate the valve or stopcock S it is necessary to remove the padlock 11, the pin 10 and then remove myattachment.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been disclosed in detail merely for the purposes of exemplification since in actual practice it attains the features of the advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. A device of the class described comprising a cup shaped member with a pair of spaced to parallel coextensive plates rising therefrom on opposite sides and having apertures at their upper ends, a pin projecting through the apertures and an inverted cup shaped cap having a channel across the top thereof for receiving the pin, said pin having a head at one end and an opening at the other end, the opening being adapted to receive a locking means.

2. In a device of the character described, a cup-shaped member adapted to receive the lower portion of a stop-cock, said member being provided with spaced parallel co-eX- tensive plates rising therefrom, on opposite sides thereof to extend along opposite sides of the stop cock, the upper end of said plates being apertured, and having their apertured ends projecting beyond the upper end of the stop cock, an inverted cup-shaped cap adapted for disposition between said plates for enclosing the upper portion of the stop cock, and a pin projecting through the apertures of said plates and bearing against the top of said cap, and means for retaining said pin in 5 engagement with said cap, and to prevent unauthorized removal of the pin.

In testimony whereof I aflix my signature.
