1 0 all whom it may concern:

Be it known that I, WILLis G. HUBBS, a citizen of the United States, residing at Walnut Ridge, in the county of Lawrence, State of Arkansas, have invented certain new and useful Improvements in Time and 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 appertains to make and use the same.

This invention relates to a time and burglar alarm.

An object of the invention resides in the provision of a device by means of which an alarm may be given when the doors or windows of a house are being forced.

A further ob ect of the invention resides in so constructing the device that it will give an alarm at a predetermined time.

Vith these and other objects in view, such as will appear as my description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims.

In the drawing: Figure 1 is an elevational view of a conventional representation of my device; F 2 is a fragmental perspective view of the circuit closer used upon the window and showing, also, the cams upon the window; Fig. 3 is a perspective view of the circuit closer for an outwardly opening door such as shown at the lower left hand corner of Fig. 1; Fig. 4 is a similar view of the circuit closer for an inwardly opening door such as shown at the upper left hand corner of Fig. 1; Fig. 5 is a fragmenta-l detail of the battery box showing the door swung to an open position; Fig. 6 is a fragmental detail of the clock receiving chamber; Fig. 7 is a sectional view thereof with the clock in place, and Fig. 8 is a diagrammatic view of the wiring.

Referring to the drawing by reference characters wherein like parts are indicated by like characters throughout the several views: In Fig. 1 of the drawing I have illustrated, conventionally, a frame 1 which in

eludes doors

2 and 3, a window at, a battery boX5 anda clock casing? A socket member 7 is mounted on the door casing and is adapted to receive a switch blade 11. A pair of switch blades 8 are also mounted on the door casing and are so formed that a space is formed bet een he ame ja e to their bases but so that they are brought into contact, resiliently, adjacent their ends. The extremities of these blades are, however, turned outwardly away from each other. A switch blade 1Ov is secured to the door and is adapted to swing between the blades 8 so that it will contact with the blades as it forces them apart in its passage to the space between the blades. When it lies in this space, however, it will be entirely free from the blades 8 so that no circuit will be completed through the said blades 8 and 10. It is to be noted that the blades 8 and the socket 7 are formed of a continuous piece ofmetal. A similar switch mechanism is provided for the door 3, which mechanism includes a socket 12, a switch blade 13 which is adapted to engage in said socket, a pair of blades 14 similar to the blades 8 and a blade 15 which is mounted upon the door 3.

Mounted on the window frame is a plate which includes a socket 16 and a keeper 17. A switch blade 18 is adapted to engage the socket 16 and a resilient blade 19 which extends beneath the keeper 17 is adapted to move into engagement with the same. Mounted on the window 4, at its upper and lower ends, are cams 20 which engage the blade 19 when the window is either raised or lowered to its full extent and maintain the blade out of engagement with the keeper. These cams permit the blade 19 to engage the keeper, however, during the raising and lowering of the window 4. A clock 21 is mounted in the clock casing 6 and is held in position by resilient plates 22 which are secured to the sides and top of the casing.

This clock is held in spaced relation to the back of the casing by abutments 23. The clock rests upon a plate 24: and a contact member 25 is secured to the back of the easing so that when the alarm key 26 of the clock rotates it will engage the contact 25. A pair of

batteries

27 and 28 are mounted in the battery box 5 while a push button 29 is mounted on the casing of the

doors

2 and 3.

Referring particularly to Fig.8 of the drawing in which the several parts which I have before described are represented conventionally, I will describe the circuit in which the parts are included. A circuit passes from the battery 28 through a wire 30, to a hinge 31, which hinge is located at the lower end of a door 32 which closes the battery box 5, through a wire 33 to a bell 34, through a wire to a hinge 36 at the upper end of the door 32, through a wire 3'? to the battery 27 to a binding post 38, which post is mounted on the battery box 5, through a wire 39 to the point d0, through a wire 4:1 to the switch blade 18, to the switch blade 19, through a wire d2 to the point l3, through a wire let to a binding post 15 and through a wire 16 back to the battery 28. Thus when the switch blade 19 engages the keeper 17 and the switch blade 18 is in the socket 16 the above circuit will be completed and the bell sounded.

A second circuit follows the first mentioned circuit from the binding post through the batteries and bell to the binding post 38 and thence passes through the wire 39 to the point 40, through the wire $1 to the point 4-7, through a wire to a hinge 49 on which the lowermost door 8 is mounted to the switch blade 15, through the switch blade 13, through a wire 50 to the point 51 and through the wire 4% to the binding post 45. Thus when the lower door 3 is opened the above circuit will be completed and the bell sounded.

A third circuit follows the first mentioned circuit from the binding post through the batteries and bell to the binding post 38, through the wire 39 to the point 52, through a wire to the switch blade 10 to the switch blade 11, through a wire 5% to a hinge 55 on which the upper door 2 is supported, through a wire 56 to the'point 57, to the point d8 and through the wire L4; to the binding post 45.

An additional circuit which includes the push button 29 follows the last mentioned circuit from the battery 27 and binding post 38 to the point 52 and thence through a wire 58, through the push button 29 and a wire 59 to the point 4:3 and through the wire 44 to the battery 28. Thus it will be seen that when either ot the

door

2 or 3 or the window l is opened, a circuit will be completed and the hell 3% sounded. In order that this bell may be sounded at a predetermined time, 1 have connected the plate 2d on which the clock 21 rests to the binding post 45 from which point the circuit passes through the batteries and bell to the binding post 38, through a wire 60 to the contact 25. lhus when the winding key of the alarm rotates, as it does when the alarm is sounded by the clock, it will engage the contact 25 and complete the circuit through the clock casing to the plate 24.

From the foregoing description it will be seen that l have provided an alarm device by means of which an alarm will be given when the windows or doors of a house are opened and l have so constructed the device that it may be set to give an alarm at a predetermined time.

ld hile l have illustrated and described a particular embodiment of my invention, it has merely been for the sake of convenience and 1 do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made in the details of construction without departing from the spirit of the invention or exceeding the scope of the appended claims.

What I claim is:

1. ln a switch of the class described, the combination with a socket, of a switch blade constructed and arranged to swing into the same, a pair of switch blades having portions of the same in contact and having a space between other portions of the same, electrically connected to the socket, and a switch blade constructed and arranged to swing between the pair of switch blades and to contact with the same during its passage to the aforementioned space.

2. in a switch of the class described, the combination with a socket and a pair of switch blades, of a switch blade constructed and arranged to enter the socket and a switch blade constructed and arranged to swing between the pair of switch blades, the said pair of switch blades having a space between the same adjacent their bases and being bent into contact adjacent to their ends.

3. In a switch of the class described, the combination with a socket, of a switch blade pivoted adjacent and arranged to swing into the same, a pair of switch blades having por tions arranged in spaced relation to each other and other portions arranged in spaced relation but relatively closer to each other, the said switch blades being electrically connected to the socket and a switch blade movable to a position between the aforementioned pair oi blades and which is of such thickness that it will contact with the pair of blades during its initial movement between the same.

i. In a switch of the class described, the combination with a socket and a pair of switch blades, of a switch blade pivoted adjacent to the socket and arranged to swing into the same and a switch blade movable to a position between the pair of blades, the said pair of blades having a space between the same adjacent to their bases and being bent toward each other adjacent to their ends.

lln testimony whereof, I a'liiX my signature, in the presence of two witnesses.
