BURGLAR-ALARM.

EBPECIFICATION forming part of Letters Patent No. 364,540, dated June 7, 1887.

Application filed August 18, 1836. Serial No.211,1$ )1. (No model.)

To all whom it may concern.-

Be itknown that I, HENRY L. PEOK, a citi- Zen of the United States, residing at Columbus,

in the county of Franklin and State of Ohio, have invented certain new and useful 'Improvements in Burglar-Alarms; 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 appertaius to make and use the same.

' My invention relates to burglar-alarms, and

contemplates certain new and useful improve ments therein.

The object of my invention is .to provlde a burglaralarm simple in its parts, reliable in its action, and in every way convenient, by

means of which any one in the apartment where my box is located can at a glance ascertain whether a door or window of the building itself or any outhouse belonging thereto is being tampered with, and if so, can immedinying drawings,'in which- Figure 1 is a view, in perspective, of the alarm-box. Fig. 2 is a vertical cross-section on line w x of Fig. 1. Fig. 3 is a vertical lougitudinal section an line y y of Fig. 2. Fig. 4 is a diagram showing the manner of connecting my alarm-box to doors and windows.

Fig. 5 is a perspective view of the appliance for connecting an outwardly-opening door to my alarm-box. Fig.6 shows a connecting device for windows. Fig. 7 represents an appliance for connecting to inwardly-opening doors. Fig. 8 represents a group of hellcrauk levers, located when in use directly over the alarm-box. Fig. 9 is a detail view, in perspective, showing the mode of attaching the connecting-wire to the alarm-box. F g. 10 represents one of the indicator-slides. Fig. 11 shows my device for line attachment to an outwardly-opening door.

My alarm-box A may be of any convenient size, and is provided with two swinging shutters, B and B, upon the inner sides of which are inclined. projections 1). Inside the box A,

located near the lower edge of each shutter, are the frames (4 a. These frames are mounted in bearings in which they turn, and are made heavier in their rear portion. Theyare connected in such manner that if one frame is moved the other moves with it, the two being always parallel, and when the shutters are closed, horizontal.

Near the top and center of the box just in the rear of the partitions H H, mounted in bearings, which allow them to turn, are the rods 0 0 0" a. Loosely mounted on these rods are the spring-tongues d d at d," d 01 (1" d Mounted rigidly on these rods are the tongues d d (1 d. The tongues 66 d d d are provided with arms a, rigidly attached thereto. There are also mounted upon these rods and rigidly attached thereto the arms 0, which opcrate the rigidly-mounted tongues.

' In the top of the box A is an opening, G, sufficiently long to permit wires attached to each of the arms 6 e to extend vertically upward therethrough. This opening may be provided with crossbars for the purpose of keeping the wires attached to the different tongues and arms separate. Directly over this opening is fixed the group of bell-crank levers D. (Shown in detail in Fig.8.) These are equal in number to the spring-tongues and are connected thereto by a series of wires attached to said levers at the points g, and are connected at the points h with other-wires attached to the windows and doors throughout the building. The ends of each of the abovementioned tongues protrude outward through openings in the partitions H H, and upon these ends are suspended the indicator-slides F, Fig. 10, the inner sides of which are inclined near their upper extremities, and such slides are provided below said inclined portion with shoulders f, by means of which they may be suspended on the spring-tongues.

The outer side of the indicatorslides are provided with recesses, in whichthe names of the diflerent apartments may be inserted, and a finger-recess may be made near their lower extremities to facilitate the operation of raising the indicator when necessary. The slides are suspended upon the tongues, between the partition H H and the front side of the box,

in such a manner that should any one of them drop it would come in contact with the forward portion of one of the frames a a, and, being of sufficient weight to overbalancc the heavier rearward portion of said frames, would tip the same forward. Bi gidl y attached to the frame a is the arm (1 which engages a moving portion of an alarm-clock-work mechanism, which is located in the interior of the box.

In one end of my alarm-box is the door K, mounted on spring-hinges and provided with a keeper, k. This keeper is placed at such a height that when the door is closed and the frame a is permitted to take its normal position the said keeper will be engaged by a rearwardly-extending portion of said frame. At the points h of the bell-crank levers and diverging therefrom are wires attached to the different windows and doors through the building. windows and doors in any desired manner; but the following is a description of the appliances which I prefer to employ for that purpose:

For connecting a window with my alarmbox I use the device shown in Fig. 6, consisting of the plate M, rigidly attached to the top of thelowerwindow-frame. This plate is provided with ears, between which is pivoted the arm M extending slightly beyond the pivot toward the frame, and being so constructed that the pointm of the said arm can be raised no higher when the window is closed, as shown in Fig. 6. Pivoted to the arm M, and about midway of the same, is an arm, M, which engages the upper wiudow-framc. This arm may be of the preferred shape shown in Fig. 6, or of any other desired form. The upper window-frame is provided with a recess, M, in which the rounded portion of the arm M may be inserted. A wire is connected to the arm M" at the pointm, the other end of which, by means, perhaps, of a number of bell-crank levers, is finally attached to one of the levers in the group D, which is in turn connected with one of the wires extending therefrom to the alarm-box. \Vhen the lower window is raised, it is apparent that the end of the arm M", to which the wireis joined,will be lowered. This at once causes the bell-crank levers to turn, which pulls up the wire attached to one of the spring-tongues-for instance, (1*. This retracts the tongue until it releases the indicator suspended thereon,whieh falls upon the forward portion of the frame a, striking in its descent the incline b on the shutter B, causing the latter to open, thus disclosing the name of the apartment. The weight on the frame causes said frame to tip forward, thereby raising the arm a", which releases the clock mechanism and causes an alarm, and also freeing the spring-door K, which opens and allows the sound of the gong to escape.

The device whichI use to connect my alarmbox with an inwardly-opening door is different from that used with an outwardly-opening door. The former consists of a bracket, N,

These wires may be attached to the rigidly secured to the wood-work just above the door. Pivoted to thisbracket at the point it is the arm N, Fig. 7. To the free end of this arm or lever is attached a wire connected, in the manner heretofore described, with one of the spring-tongues of the alarm-box. This arm is prevented from rising above its operative position by the stop a. On the pivot 11 is also mounted the angular plate-piece N,the pivot passing through a curved slot, r, in said plate. Thehorizontal portion N of this plate extends inwardly to near the end of the bracket N, and is provided near its extremity with a pin, a", which engages a notch or recess in the bracket. This angular plate-piece is provided near the junction of its members with asmall lip, a, projecting over the arm or lever N a short distance from its pivot, and the arm or lever N is provided with a lip projecting under the rearwardlyextending arm N of the angular plate-piece. The pendent arm ofthis plate-piece when in its lowest position is in the path of the door when movcdinward, and the door coming in contact therewith will cause the same to move, by reason of its 011- gagement with lever N through lips Maud a", and move said lever, causing an-alarm, as heretofore described. The inner side of the penden't arm N is made inclined, so that on closing the door will raise the same out of its path, the arm moving freely upward on the pivot a by reason of the slot r.

I may, instead of operating the angular plate directly by the door, employ the plate mounted adj ustably upon the inner side of the door. This plate is shown in the drawings as mounted in guide-loops 0, attached to the door and provided with the inwardly-extending arm I, having an upward projection, p,- but this plate may be attached to the door in any other desired manner. For example, the said plate may be provided with one or more slots and be attached to the door by screws passing through the same. This plate is made adj ustable, so that when moved downward into its lowest position it will pass beneath the pendent arm of the angular plate-piece, and while thus depressed the door can be freely opened and closed without setting the alarm mechanism iuto operation; but when raised to its higher position, on opening the door it will engage the pendent arm of the plate-piece, and an alarm will be sounded.

My device used to connect the alarm-box with outwardly-opening doors consists of a bent frame, R, attached firmly to the under side of the upper cross-piece of the door-frame, and yoke R, sliding on said frame R by means of the loops 8.

To the frame part of the yoke is attached a connecting-wire. means either of guide-loops or screws passing through the slots 8 is the adjustable catch R, designed to engage the yoke at the point T when the catch It" engagesthe yoke R, which, being connected with the box A, causes an alarm in manner hcreinbefore set forth. As

IIO

Secured to the door by the door continues to open the yoke slides along the frame R until the portion of said frame which is bent upward raises the yoke until the catch It is rcleased,and thus prevents breakage.

What I desire to claim, and secure by Letters Patent, is

' the same above said weighted frame, and connections leading from said spring-tongue to the door or window, substantially as described.
