UNITED srarns PArN'r orrron.



To all whom it may concern:

Be it known that I, HOWARD S. GARDNER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Safety-Locks for Faucets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to safety devices for locking the handles of faucets so as to prevent them from being used improperly; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of the safety device applied to a faucet. Fig. 2 an end view of the clamp. Fig. 3 is a plan view of the clamp.

A is a faucet of any approved construction, provided with a plug valve B having a handle 5.

C are two curved bars arranged parallel to each other and provided with eyes 0 at their ends. These bars are formed of flexible metal so that they can be fitted and adjusted to the underside of the faucet, one on each side of its plug.

D and E are two plates provided with sleeves (Z and e at their bottom edges, which are pivoted to the eyes 0 by means of pins (Z' and e. The plate D is flat and it has a notch f at its upper edge for engaging with the handle of the faucet. The plate D has also a laterally projecting lug f on one side of the notch. The plate E has a flat por tion E arranged parallel to the plate D, and this flat portion and the plate D are provided with holes 9 for the hasp of a padlock G. The plate E is curved to form a hood which partially encircles the plug of the faucet, and this hood has a fiat top por- Specification of Letters Patent.

tion it which rests on the top of the plug. The lug j" of the plate D projects over the top portion it so that the whole clamp is rigid when applied to the faucet.

The padlock G is of any approved construction, and any other approved locking device may be used in place of it, which will hold the clamping plates rigidly in position. When the clamping plates are looked upon the faucet, it is impossible for anyone to operate the handle without first unlocking the padlock and removing the clamping plates.

\Vhat I claim is:

1. A safety lock for a faucet, comprising two bars which straddle the faucet, t-wo clamping plates pivoted between the said bars, one of the said plates being fiat and having a notch for engaging with the handle of the faucet, and the other plate having a curved hood which fits partially around the faucet, and a locking device for securing the said plates on the faucet.

2. A safety lock for a faucet, comprising two bars which straddle the faucet, two clamping plates having their lower edges pivoted between the ends of the said bars, one of the said plates being provided with a notch at its upper edge for engaging with the handle of the faucet and having also a laterally projecting lug at its top, and the other plate being provided with a curved hood which fits partially around the faucet and which has a flat top portion which engages with the said lug, and a locking device for securing the said plates together and in engagement with the faucet.

In testimony whereof I have affixed my signature in the presence of two witnesses.
