JOHNSON M. QUINBY, OF WESTBROOK, AND A. S. DYER, OF CAPE ELIZABETH, MAINE.
Letters Patent No. 112.076. dated February 271, 1871.
IM PRQVEMENT I N DOOR-LOCKS.
The Schedule referred toin these Letters Patent nd maldng part of the same.
To all whom it 'may concern:
Be it known that we, JOHNSON M. QUINBY, of Westbrook, and A. S. DYER, of Cape Elizabeth, both in the county of Cumberland and State of Maine, have invented a new and useful Improved Door-Lock; and we hereby declare the following to b e a full, clear, and exact description thereof, which will enable others to make and use our invention, refei'ence being had to the accompanying drawing forming part of this specication, in which- Figure l is a view of a portion of a common knob with our invention thereon.
Figure2 is a view of an escntcheon with lthe slot to receive the slide.
Figure 3 is a section of the shank, showing the position of the slide.
Our invention relatest-o a new and useful method of fastening an ordinary knob-latch, and consists in a slide working in a slot on the shank. and-fitting, when desirable, a slot in the escutcheon.
The locks or latches to which this invention relates :ire the common spring ones, operated by a knob grasped by the hand. (See a.)
b is its shank.
c, the escnteheon, which is screwed to the door.
l is the square part of the shank, passing through the door, and which operates the latch.
e'is a slot in the escutcheon.
0n the shank b we make a slit, fiaring at the bottom thereof. (See f.)
Int-o this we put the slide h, conformin f n shape to the slot, and so vbeing'kept therein. is slide moves backward and forward in the slot.
When drawn backward, or so as not to enter the' slot in the escntcheon, then the knob will turn freely as usual.
When pushed forward so as to enterthe said slot, the knob cannot be turned without drawing back said slide. This is intended, of course, to be applied on the inside of the door, or within a room or a house. No other lock is then required.
. The onlychange in an ordinary knob-latch is the slide, the slot in the shank, and the slot in thc escutcheon. l
A small thumb-piece, L, may render the slide easy to manipulate. y
We are aware of Letters Patent No. 44,407, issued to Amos Oall, March 7, 1846, and to John Adt, December l1, 1860, No. 30,902, the first-named being for a method ofy freeing or attaching the knob from or to the spindle by means of a bolt acted upon on the opposite side of the door. This we do not claim, and it is different in construction and operation from ours.
The second-named is for the arrangement of.. a-
spring, a ring provided with two depressions, two lugs, and a slot, with a shank-box and pin, and a notched rose. 4In this the combination oi' devices and the operation thereoi' are wholly different from ours, and .ve do not claim it.
Our invention is or' greater simplicity, consisting,
Vas it does, of the slide and the slot in the shank.
What we claim as our invention, and desire to secure by Letters Patent, is-
The slide h, working iii the shank b, and capable of being pnslied into the slot ein the cscntclieon, as herein described, and for the purposes set forth.
