STATES LYMAN RHOADES AND JOHN PHILIP SIPI, OF NEWV YORK, N. Y.

KEY- HOLE GUARD.

SPECIFICATION forming part of Letters Patent No. 289,446, dated December 4, 1883.

Application filed August 1, 1883. (No model.)

.To ctZZ whom it may concern:

Be it known that we, LYMAN RHOADES and JonN PHILIP SIPP, citizens of the United States, residing in the city, county, and State of New York, have invented a new and useful Lock-Guard forLocks having attachedto them H. R. 'Iownes key-hole guard, patented May 1 17, 1870, N 0. 103,256, and for the well-known expense.

Our invention is of great use to safe-deposit companies, when, for any reason it is desired to prevent a'boX-renters box having one of said locks on it from being opened with its regular key except by a person properly authorized, and to prevent its being accidentally opened by an attendant causing the seal which may be attached to it to be broken. WVe attain these objects by our invention shown in the accompanying drawings, in which-- Figure 1 represents our invention. and the manner of applying it to alock having Townes invention attached to it, and Fig. 2 represents our invention and the manner of applying it to the Perry lock and the Isham lock.

Similar lettersrefer to similar parts throughout the several views.

00 represents what, for the sake of description, we shall call in both figures the key-hole of the lock to be guarded.

(t represents a straight piece of metal with a handle, for the purposes hereinafter described.

8 represents an eye-hole in the handle of a.

72 represents a piece of thin metal shaped to fit on the locks, as shown in the several views.

it represents an eye-hole in the raised part lock to be guarded and Townes invention atand of the Ishamlock. Drepresents the same as O with our invention applied to it. D represents aside view of G with our invention applied to it. E represents aside view of (J,

showing one of the two pins for fastening the register to the lock. 1) is shown as shaped and arranged to fit on the face of G; b as shaped to fit on O, and consists of a piece of thinmetal bent at about a right angle, with eyeholes y and t, one in each face. In the drawings only the eye-hole 3 is shown. Z represents the pins intended for the register of the lock 0, and used to fasten b to its face. an and n represent slots for attaching b to the look by means of the pins Z. 3/ represents an eye-hole in b.

As is shown, we obtain the object of our invention by inserting a piece of metal into the lock to be guarded, and attaching :a second piece to the outside, the two being so formed that when inserted and attached they cannot be removed together, and then fastening the two together, thus preventing their removal and guarding the lock.

To use our invention on a lock having Townes said patent attached to it, we attach b byslipping it on z until the eye-hole t in 1) comes opposite the key-hole x. We next insert a into the key-hole of the lock to be guarded. (In the drawings a Yale key is shown, as well as a, as the key of the lock to be guarded may often be used; but for manifold reasons we prefer to use a straight piece of metal, even when the regular key can be obtained.) The 5 eye-hole s is so placed in a and the eye-hole t in the upright face of b that when 12 is attached and or inserted, as described, the eye-holes s and i come alongside of each other. We then fasten a and I) together, which may be done, as shown in the drawings, by passing the shackle of a padlock through the eye-holes s and 15, when it will be found that a and b cannot be withdrawn until released from each other, they cannot be removed together, the regular key cannot be inserted into ac, and consequently the lock will be guarded and our object attained.

To use our invention on the Perry and Isham locks, 11 is so shaped that it may be attached in the same way as the register of the lock is attached.

The large Perry and lshain locks have faces similar to that shown at C. In these the register of the lock is attached by means of pins Z and slots in the register similar to the slots in and n in b. In locks of this kind our invention is operated as follows: \Ve attach b to the face of the lock by means of the slots m and n and pins Z in the same manner that the register of the lock would be fastened. The eye-hole g is so placed in Z) that when I) is so attached it (7 comes directly over what we call the key-hole x. We next insert a through the eye-hole y into the key-hole x. As before, the eye-hole s is so placed in a and the eye-hole t in the upright face of b that when 11 is attached and a is inserted, as described, the eye-holes s and t come alongside of each other. V e then fasten a, and b together, as set forth, when it will be found that a and I) cannot be withdrawn until released from each other, they cannot be removed together, the register cannot be attached to the lock, and consequently the lock will be guarded and our.object attained.

In the small Perry and Isham locks the face is similar to that shown at G, the register being attached to the face of the lock by being slipped into the grooves shown at O and D. To operate our invention in these, we attach b by slipping it into the grooves, in the same manner as the register would be fastened, until the eye-hole y is over what we call the key-hole 00. On the face of the lock is usually a pin to stop the register in its proper place when being slipped on, and b is so made that when stopped in the grooves by said pin absolutely to the eye-holes s and t, as, instead of eye-holes, rings may be fastened to a andb, through which the shackle of a padlock may be passed. \Ve have simply described and shown the method of application that we prefer.

Having described our invention, what we desire to secure by Letters Patent is- 1. A lock-guard constructed of two parts, substantially as described-one part, as a, adapted to be inserted into the key-hole, the other part, as 1), adapted to be attached to the outside of the lock-the two parts being provided with means for attaching them together when in position, substantially as and for the purposes described.

2. The combination, in the hereinbefore-described lock-guard, of the straight piece of metal a, having an eye-hole, s, at its outer end, or the end not inserted in the lock, the piece of metal I), having an eye-hole, t, and means, substantially as described, for attaching it to the outside of the lock, and the padlock c, all constructed substantially as described, so that when a is inserted in the lock and I) attached to the outside the two may be fastened to- '80 gether by means of the padlock c and eyeholes 8 and Z, substantially as and for the purposes described.
