SAFE-ALARM.

SPECIFICATION forming part of Letters Patent No. 415,413, dated November 19, 1889. i

Application filed-August 9, 1889. Serial No. 320,242. (No model.)

To all 1071mm it Hwy concern:

Be it known that I, AARON D. MILLER, a citizen of the United States, residing at Evansville, in the county of V anderburg and State of Indiana, have invented certain new and use ful Improvements in Safe-Alarms; and I do 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 has relation to improvements in alarms for safe-doors and drawers or the like, and the novelty will be fully understood from the following description and claims, when taken in connection with the accompanying drawings, in which Figure 1 is a front view of a safe with the doors removed and my improvements applied. Fig. 2 is an inverted plan view of my improved device with the bell or gong removed, and Fig. 3 is a side elevation with the gong in position and in section. Fig. 4. is a view in perspective of the lever E, showing roller 2'.

Referring by letter to the said drawings, A indicates a plate, preferably of metal, and may be of any suitable shape. This plate is provided on its under side with a central depending post a, to the outer end of which is secured the gong B. Arranged at one side of this post a and depending from the plate A is a post b, to which the handle or arm of the ham mer. C is secured. This hammer-arm is preferably composed of spring-wire, and is coiled around the post I) in the form of a spring having its opposite or free end (Z engaging a post 6, which serves as a stop.

D indicates a vertically-depending post arranged on the under side of the plate A and upon which is journaled a lever E. This lever has an arm f, adapted to be engaged by a trigger which will be presently explained, and the said lever is also provided with an arm g, engaged by the arm of the spring-actuated hammer. Said lever is furthermore provided with a stop 6, adapted to be engaged by the arm of said hammer at each stroke of the gong.

the trigger or lug on the slide-bar,l1ereinafter referred to.

F indicates a slide-bar, which is provided at suitable points with elongated slots 72., whereby the said bar is movably held to the under side of the plate A by means of screws it, or other suitable holding devices. This slide-bar, which has its forward end projecting sufficientlyfrom the forward end of the main plate, is backed by a spring.

In the present illustration I have illustrated a spring for throwing the slide-bar forwardly, which is composed of a wire II. This wire is coiled around the post I with one end stopped by the post or lug e and its opposite end bearing against the rear end of the slide-bar F. It is obvious that other forms of spring may be employed, although the one I have shown is preferred, it being simply necessary to have a spring which will normally hold the slide-bar F in an advanced position. This slide-bar is provided with a trigger or lug G, arranged at a point to engage the beveled arm fof the lever E when the former has been reciprocated or moved in either direction.

L indicates a bracket, which is provided with one or more elongated slots at its rear end, and is adjustably held to the forward end of the main plate by means of screws l or other fastening devices. This bracket, by means of the elongated slots and fasteningscrews, is rendered longitudinally adjustable, and is provided near its forward end with a vertical flange m, having an aperture for the reception of a screw or the like, whereby it may be fastened in position upon a drawer or other article.

M indicates a lateral arm, which may be composed of metal or other suitable material. This arm has its inner end arranged in an aperture in the lever E, as shown,and is adjustably held therein by means of a set-screw n. This lateral arm is designed to operate the alarm by the opening or closing of a drawer.

In operation the plate A is secured to the under side of the shelf or other part of asafe by passing screws or other devices through the apertures N and also the aperture in the forward end of the bracket L, the latter being adjusted to suit the article to which the device is to be attached. The drawer in connection with which this device is to be operated should have means of engaging the arm M, so as to manipulate the alarm. The drawer may have a lug, or it may be slotted to receive the arm M; or any other construction may be employed, according to the fancy of the user. hen the plate and its bracket have thus been secured within a safe, the arm or bar F will lie in a position to be engaged by the inner side of a door of the safe. Thus when the door has been closed the slide-bar F will be pushedinwardly, compressing the spring H. Now when the door has been opened, the slidebar shooting forwardly by the action of the spring, its trigger G will be brought to engage and move the leverE upon its pivot, and as the trigger disengages from the beveled arm f of the lever the arms 9 and i, through the medium of the spring-arm of thehammer, will cause an alarm to be given. It will also be observed that by moving the arm M either forwardly or backwardl'y the lever will be similarly acted upon and consequently the hammer of the gong, thereby giving an alarm at the opening and closing of the moneydrawer as Well as at the opening and closing of the safe-door, and it will be readily seen 1 that while the drawer-alarm or mechanism for operating the same will serve independent of the mechanism for operating the alarm when the door has been opened, yet both of these devicesare so connected that they maybe worked in conjunction with each other and at the same time.

While I have shown and described my invention as applied to a safe and one of its drawers, yet I do not wish to be confined to such application of its use, as it is obvious that it may be employed upon doors of various kinds and drawers of various articles of furniture. Furthermore, I provide the lever E with a friction-roller 'r in a recess or seat in the point of the arm 9, which roller engages the arm of the spring-actuated hammer and permits the latter to work more readily and easily.

Having described my invention, what I claim is 1'. In an alarm for safe-doors and drawers,

carrying a trigger or lug, a spring backing the slide-bar and coiled around the post, a lever having one arm adapted to engage the trigger, and two stops or arms adapted to engage the arm of a hammer, an aperture to receive an arm, a set-screw passing into said aperture, an arm arranged in the aperture and adapted to be engaged by a drawer, and a longitudinally-adjustable bracket secured to the main plate, substantially as specified.

2. In a safe-alarm, the combination, with the mainplate, of the lever journaled on the under side thereof and having a beveled arm f adapted to engage a trigger, and the two arms g and 1', adapted to engage the arm of the hammer, a gong having a spring-actuated hammer limited by the movements of the trigger-lever, and a slide-bar carrying a trigger, substantially as specified.

3. The combinationnvith the main plate, of a slide-bar carrying a trigger and held forward by the action of a spring, a pivoted lever having a beveled arm f adapted to engage a trigger on the slide-bar, and having arms g and z for limiting the movement of' a spring-actuated hammer and a gong, substantially as specified.

4. The combination, with the main plate, of

i a slide-bar adapted-t0 be engaged by a safedoor and moved thereby, a spring engaging one end of a slide-bar so as to keep its opposite end advanced, a trigger on the slide-bar, I a gong, a spring-pressed hammer, and a pivoted lever having a beveled arm adapted to be engaged by the trigger of the slide-bar, and two arms. adapted to alternately move and limit the movements of the spring-actuated hammer, substantially as specified.

5. The combination, with the main plate, of a gong secured thereto, a pivoted lever having two. arms adapted to alternately move and limit the movements of the hammer of the gong, and a laterally-adjustable arm secured to the lever, substantially as specified,

6. The combination, with. the alarm mechanism, of thelever E, provided with a frictionroller 1' in a recess in its arm, and the hammer-arm engaging said friction-roller, substantially as specified.

In testimony whereof I aifix my signature in presence of witnesses.
