HENRY YERTY, OF SIDNEY, OHIO.
IMPRovl-:D BURGLAR-ALARIW.
Specification forming partof Letters Patent No. 59,307, dated October 30, 1866.
To all whom it may concern:
Be it known that I, HENRY YERTY, of Sidney, in the county of Shelby and State of Ohio, havein vented a new and useful Improvement in Burglar-Alarms; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which are made a part of this specification, and in which- Figure l is a plan of a double-barrel shooting arrangement illustrating my invention. Fig. 2 is a vertical section of the same, the line a', Fig. l, indicating the pla-ne of section.
Similar letters of reference indicate corresponding parts in the different figures.
This invention relates more especially to the class of protective devices which are made to fire upon burglars or give warning of their approach by a slight pull or tension upon a cord connected with the trigger of the lirearm, and attached to some fixed or movable point, such as a post, door, or window.
The present improvement consists in so mounting the barrels or shooting device and\ connecting the cord thereto that the barrels shall, by the tension upon the cord, be brought in line with and made to fire accurately at the point where the cord is acted upon, and thus au approaching burglar may be inevitably shot in passing across the line occupied` by the cord.
The following description will enable others skilled in the art to which my invention ap- Y pertainsto fully understand and use the same.
In the drawings, A A may represent two barrels, connected together at their rear ends by the curved breech-piece or bar B, and
)mounted upon a pivot, E, which passes throughA v the transverse part C, and is fitted in the standard D, which rises from the part C, as seen in Fig. 2. The part G is simply a suitable bearing-point for the pivot E, and is joined to the barrels A A.
The pivot E is attached to a separate clamp, F, which maybe made fast to a table, post, or any suitable fixture indoors or outdoors, so as to leave the barrels free to vibrate in a horizontal plane upon the pivot E.
Behind the part O, and journaled in the opposite sides of the breech-bar B, is a shaft, G, from which rises an arm, H, to the upper end of which is attached the rod I. `The rod I has attached to its forward end a cord, I',
which is attached to a door, window, post, orl
any stationary or movable point, and undergoes tension applied either by the opening of the door, window, &c., or by the direct contact of the person of the approaching burglar.
A lock arrangement is employed in connection with each barrel to actuate the hammers J J, the dog K of each lock being actuated by a spring, L, and made to release the hammer J by the projection N on the shaft G, which projections (one being located near each end of shaft G) are depressed by the partial rotation of the shaft G, caused by the tension applied to the cord I'.
The rod I maypass through an eye in the standard D', and extends forward through an aperture in the transverse bar O, attached to the forward end of the barrels. Hence, when tension is applied to the cord I', the barrels, if not already in line therewith, will be directed accurately toward the point where the cord is acted upon, and the continued tension, acting through the arm H, partly rotates the lshaft G, and thus actuates the. dogs of the respective locks.
Thus the barrels are not discharged till they are leveled at the approaching object, which makes the device doubly effective, it being a medium of destruction as well as of detection.
A plurality of cords, I', extending in different directions, may be employed in connection with each gun.
The device will be found useful not only as a protection against burglars, but as a means of preventing the depredations of animals 5 and its application maybe extended to heavy guns and military purposes generally without departing from the essential feature of the invention.
One or more barrels operating in the same way may be employed, according to the requirements ofthe occasion.
Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent:
1. One or more barrels mounted upon a pivotor axis, and employed in connection with a rod, I, extending forward of the axis C E, To the above specification of my improveand having,` attached to it one or more cords, ment in burglar-alarms I have signed my hand I', whereby the barrels are directed toward an this 27th day of June, A. D. 1866.
approaching objectby the object itself, and
then discharged, substantially as described. m HENRY YERTY.
2. The combination, with the swiveled gun i A A, of the shaft G, arm H, rodrI, and cord I', Witnesses:
the whole being arranged to operate in the CEAS. D. SMITH,
manner and for the purposes herein described. JAMES L. EWIN.
