Letters Patent No. 99,577, dated February 8, 1870.
IMPROVEMENT IN KEYS.
The Schedule referred to in these Lettersatent and making part o! the same.
'To all 4whom t may concern Be it known that I, JOSEPH LINDER, of Seneca Falls, in the county of Seneca, and State of New York, have invented a new and useful Improvement in Keys for Locks; -and I do hereby declare that the following is a full, clear, and exact description thereof',
with my improved key.
Figure 2 is a longitudinal section of the key, showing it in the lock.
Similar letters of reference indicate corresponding parts. y
This invent-ion relates to a new key for door and other locks, and consists in the application to the key, of a pivoted plate, which has a cam-projection for `forcing out the bit on its free end, when the key is introduced in the lock, and is arranged, in connection with a spring, .whereby it is forced back into the slot in the key, cu withdrawing the latter.
The key A has a slotted shank, between the cheeks of' which the bit a is held. v
The bit is an ear formed on the lower end 'of' a plate, B, that is pivoted by a pin, b', between the cheeks of the shank. From the plate B projects, nearer to the pivot than the bit, a cam, c, which, when the ward is concealed between the cheeks, projects from the shank.
A spring, d, which is attached to the shank, presses against that edge of the `plate Bthat is opposite the the cam c.. l
'A plate, e, prevents the plate from being thrown too far by the spring.
When the key is introduced in the circular key-hole of the lock-plate C, its bit is drawn between the cheeks. Vhen the cam strikes the lock-plate, it is, as its bevelled edge receives the pressure, forced into the shank, while t-he bit is thereby thrust out, as in fig. 2. The hit is now in a position to raise the tumblers D, and move the bolt E of the lock. While the bit is thus forced ont, the spring d is pressed out by the plate B, as shown. When the key is withdrawn, the bit will be again concealed by the spring as soon as the cam has cleared the lock-plate C.
.Having thus described my invention,
I claim as. new, and desire to secure lby Letters Patent' The slotted key, coytaining the pivoted plate B, which carries the bit a and the cani c, and is acted upon by the springd, substantially as herein shown and described.
