IMPROVEMENTS IN DOOR LOCKS
Year: 1885

page_text: I, THOMAS INNES GRAY of 129 Bowes Street, Waterloo, Blyth Northumberland
Blacksmith, do hereby declare the nature of my invention for IMPROVEMENTS IN
DOOR LOCKS to be as follows:-
My improvement consists of the double action of one locking bolt, (instead of
two as at present in use) by turning the handle the bolt is lifted to act as a sneck
or latch which answers the ordinary purposes for snecking, & opening of door,
. When the door is required to be locked-a small key is inserted by which the
same bolt is thrust further out, & thereby renders the aforementioned handle
inoperative & locks the door.
The second part consists of a partition plate so placed inside opposite the key
hole, a pin is so fixed in the plate, so as to project opposite the keyhole on both
sides, on which pin the key revolves in movable wards, the said plate requiring
1.ressure from without by inserting the key; when the key is withdrawn the plate
springs back in front of the hole.

page_text: I THOMAS INNES GRAY 129 Bowes St. Waterloo, Blyth, Northumberland,
Blacksmith, do hereby declare the nature of my invention for IMPROVEMENTS IN
DOOR LOCKS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
-
My Improvement consists of the double action of one locking bolt, (instead of
two as at present used) by turning the handle the bolt is lifted to act as a sneck,
or latch, which answers the ordinary purposes for snecking & opening of the door,
When the door is required to be locked, a small key is inserted, by which the same
bolt is thrust further out, & thereby renders the aforementioned handle inoperative,
& locks the door.
The second part consists of a partition plate which being circular in form,
answers the purpose of a revolving ward, which is herein named a partition,--or
ward-plate, so placed inside a guide-ring, opposite the key-hole, with (or without)
pin fixed in the plate, so as to project on both sides, on which pin the key is turned
& moves the revolving ward-plate, the aforesaid ward-plate moving in a circular
guide-ring on the back of the lock inside.
Furthermore, the internal part of my lock consists of a fixed circular ward, in
which a revolving ward moves as turned by the key, the aforesaid fixed ward being
a guide to the revolving ward, both the aforementioned wards are made to corre-
spond with each other, having various designs with corresponding key, so that the
key which is designed for one lock-will not fit another.
When a pin is fixed in the ward plate, a hole is made in the key to fit the same,
or, when the plate has no pin fixed in it-the hole is in the ward plate & the pin
is on the key which is inserted--corresponding with the aforementioned hole.
Whether with, or without fixed pin, or spindle, the revolving ward has a crank,
which acting like an eccentric, causing the bolt to lift off the catch pin & move
foward, and when moved forward the catch pin slips into a second hole-which
prevents the said bolt from slipping back, unless the key is inserted to turn the
revolving ward, When the bolt is back in the lock it can be used as a latch, or
sneck, by turning the handle to which a small lever is attached which presses on
the bolt, The aforementioned catch-pin being so placed to act as a fulcrum on
which the bolt is tilted by the pressure of the lever, placing the bolt in such a
position as may be used for snecking purposes.
The use of springs is obviated by my contrivance.
The cost of my lock is small because it consists practically of only two parts, viz,

page_text: Figure III shows front section of ward plate, marked B, & end section of ditto,
marked B, B, with tumbler or crank, marked O, Also back section of ditto
marked E, P.S. The partition plate, & movable ward are one & the same.
Having now particularly described & ascertained the nature of my said
Invention, & what manner the same is to be performed, I declare that, what
I claim is
First. The revolving ward, in whatever form, or shape, it may be made.
Second. I claim also the crank, or tumbler; placed in such position as I have
described.
Third. I further claim that if any person, or persons, make, or cause to be made,
a lock with a revolving ward which is moveable for the purpose of locking, is an
infringement of my Patent rights.
