EMPROVEMENT I N PADLOCKS.
Specification forming part of Letters Patent No. 129,979, dated July 23, 1872.
To all whom it may concern:
Be it known that I, WILLIAM WrLcox, of Middletown, Middlesex county, State of Conneoticut, have invented a certain new and useful Improvement in Bridge-Wards for Locks.
The following is a specification thereof:
The object of my invention is to produce a cheap and substantial bridge-ward for looks;
and it consists of a thin metal plate punched in such form that it can be placed into the recesses or ways for the bolt by entering one arm into the hole of the front post, through which the bolt passes, and the other arm into the slot of the opposite post, it being kept in position by a projection on the tumbler in the same manner that the bolt is retained.
To enable others to make and use my improvement, I will proceed to describe the same,
- referring to the drawing hereto annexed.
Figure lrepresents the form of my improved bridge-ward, which is made from thin sheet metal-a a the arms to fit into the recesses or ways for the bolt. Fig. 2 represents the bridgeward in its position in the recesses or ways for the, bolt .in the posts I) b, where it is held by the projection e on the tumbler. A slot is made in the end of the key-bit k, which admits the bridge-wardv while the key is raising the tumbler d and carrying the bolt 0.
fourth, riveting the same to the posts. Wards.
made in this mode are liable to be displaced, so as not to enter the slot of the key, while by my improved mode of making they are simply punched from thin sheet metal and dropped to place when the lock is assembled.
What I claim, and desire to secure by Letters Patent, is
A sheet-metal bridge-ward, provided with arms a a, oneof which isplaced in the hole of the front post, through which the bolt passes, and the other arm placed in the slot of the opposite post, and is held in position by a projection, e, on the tumbler.
