TO WHOM IT MAY CONCERN:
Be it known that we, LYMAN W. BLAKESLEE and ALGERNON D. SMITH, both of Cincinnati, Hamilton county, State of Ohio, have invented a new and usefulBurglar-Alarm; and do hereby declare the following tol be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.
Our invention relates to an automa-tic alarm, capable of being set to operate. by the opening of a door, or of being temporarily thrown ont of operation when the door is required for family use.
Figure 1 is a perspective view, showing the door closed and the alarm set.
` Figure 2 is a perspective view, showing the door open and the alarm locked.
A is an alarm, having the customary alarm-movement or parts B C of a common clock. E is a rod., projecting from the pallet (l. This movement is enclosed-in a 'case or box, F, having asiat, f, through which the rod E protrudes, and in which, whenthe alarlnis in actionkitplays.- The box F is fastened to the inner side of the door, near its top, and near the freeedge thereof. Attached to the door-jnmb, and projecting therefrom, is a tongue, G, which slopes upward on its under side, and is level or slightly upturned on its upper side.
While the door is shut, the tongueG holds down the rod E, and prevents an alarm, but the opening of the door, by liberating the rod, sets lthe alarm at liberty. For day use, when the alarm is not required, the rod E is heldV down by a hook, H, so as to enable the. door to be used freely, without disturbing the' alarm, and so that once winding up the alarm would serve until it is discharge'd'by burglar-ions hands. The alarm is wound in the usual way, by a key applied to the arbor D. s
I isla, sliding door to the box, having anaperture, z', for the insertion of the Winding-key.
We claim herein as new, and of our invention- Y The combination, with the alarm A andthe rod or trigger E, of stationary curved tongue r catch G and hook H, all applied and operating in the manner-and for the vpurpose set forth.
In testimony of which invention, .we hereunto set our hands. I'
LY'MAN W. BLAKESLEE, ALGERNON D. SMITH.
