Letters Patent No. 104,195, lated June 14, 1870.

IMPROVEMENT IN ALARM ATTACHMENTS FOR LOCKS AND BOLTS.

The' vSchedule referredv to in these Letters Patent and making part of the same Kuow all men by these presents:

That I, CHARLES E. Plenos, of the city, county audSt-ate of New York, have invented certain new and useful Improvementsin Nose-Pieces with an Alarm Attachment, and to be used in connection with bolts for doors and windows, also, to be used in connection with all'kinds of locks having an extra bolt or lock attached, and as described below; the following is afull, clear, and exact description thereof, reference beingr had to the annexed drawing makin g a partl of the same, in which- Figure 1 represents a'common bolt, with a lever attached tothe nose-piece.

Figure 2 represents a nose-piece with lever attached,

vand is designed' to be used in connection with a doorlock placed upon either side ot' a door;

Figure 3 represents a nose-piece or plate with one ormore levers attached, and is designed to be used more particularly in connection with mort-ised locks.

Toall of said'figures, 1, 2, andv3, are attached au alarm-bell, which is more minutely described below.

Figure 1P, on iig. 1, represents the under part of the nosepiece with lever 2" adjusted to it.

a' represents that part of the lever which cornes.

iu contact with the bolt when shoved into the nose piece.

`(l represents the plan lwhen the pin passes through the lever and into each side of the nose-piece.

b represents the end of lever to which is attached cords or wires D to start the ala-rm.

` Figure-2 representsaside view of a nose-piece with lever attachment, and is used in the same manner as described above, and will be shown in describing g. 3.V

Figures 3P 3f" 312 represent three levers which are fastened to standards E F G, shown on fig. 4, also shown and connected to each other ongi. Saidlevers 3P 3l El"2 on tig. 3,'may be placed ou either end of the same it desired.

Figurep or lever 31 is fastened at or near its ceutcr H,between standards Gr and E.

D, ou lever 3f', is a hole, through which passes end c c of lever 3l".

D on lever 3P represents a cord or wire, and

D D the hole in said lever 3 where thecord or wire is fastened.

Figure 31 Ior level' 3 is fastened to standard F, shown on g. 4.

Figure 3P or lever 3Z is fastened at l, between standards E E onflg. 4.

-b b ou figure 312 represents a hole, through which is inserted end c on lever 3N.

a a represents one end: of lever 3"2,`and is that part which the extra or inside bolt or lock, other than the ordinary lock rests against, when shoved into the nose- `piece or plan, indented in said nose-piece to keep the door more securely bolted or locked.

W'hen the different nose-pieces. above described, ar'elproperly fastened to a door-jamb-or frame, and the different locks or bolts intended foreach nosepicce are properly placed ou La -door to iit the nosepiecc, andthe door locked, and an alarm-bell is fastened to either of the above-described levers, attached -to the different nose-pieces by means of cord or wire D', should any. person from the outside succeed in un' locking the door, by means of afalse key or otherwise, and an attempt be-inade to force the door open, the inside bolt yet remains locked or iu the nose-piece, and resting against `ends a aa ma on levers 2F; 3", and 3PZ, causes cord or wire Dto turn and sound an alarm, the said cord or wire D'. being connected at one end to the lever and the other to lthe alarm-bell; while, at the same time, `the door remains securely locked or bolted.

The levers above described maybe attached to any nose-piece, and used in connection with any kind of a bolt or lock of any size. l

I am aware that levers have been placed in the keeper before, and so arranged as to be released and lthe alarm operated by vwithdrawing the bolt. Also, that levers have been pivot-ed on the door-casing in Contact with the end of theholt, so that, when au attempt is made to force the door'open without withdrawing the bolt, it will operate the lever and through it the alarm.

My improvement consists in so pivoting the lever in and to the keeper, nose-piece, or plate, that when an`V attempt is made to force open the door without withdrawing thev bolt, the end of thel latter will come in contact with the lever and operate the alarm, while the bolt is still retained in the keeper.

Having thus described myimprovcd method for alarm attachments to nose-pieces, for dilerent locks or bolts, and the manner in which the same may be used,

What I claim, therefore, is

The lever, when arranged inarecess on a keeper, nose-piece or plate, so as to'be operated by the end ot' -the bolt before the latter is withdrawn, in the manner above described.

CHARLES PIERCE.
