PROVISIONAL SPECIFICATION.
Improvements in Bolts and Locks for Doors and the like.
I, JOHN THOMAS, of Castle Cary, Somerset, Builder and Contractor, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in bolts and locks for doors and the like
and has for its object to provide an inexpensive and simple locking arrangement
whereby doors can be fastened conveniently and more expeditiously than was
heretofore possible.
In carrying my invention into practice I screw or otherwise attach upon a con-
venient part of the door, for instance, to be locked. a plate of wrought iron or
other suitable material to the centre of which I pivot (at a point near one of its
ends) a handle or lever which passes along the lock rail of the door and is capable
of being secured in position upon the same by means of a reversible clip pivotted
to the said handle or lever in combination with a staple fixed on the door and
an extraneous padlock.
To the pivotted end of this handle or lever I pivot one on each side of the said
pivot, longitudinally from said pivot and equi-distant from the same two bars of
metal or, other suitable material constituting bolts which pass upwardly and down-
wardly, respectively through the usual guides on the door and thence into the
hasps, or sockets above and below the door, when the handle or lever aforesaid is in
a horizontal or locked position. These bars of metal aforesaid (hereafter to be
termed bolts are bent inwardly at their pivotal ends so as to be in a vertical line
one with the other.
In operation when the handle or lever aforesaid is raised out of the horizontal
position the upper bolt is drawn down and the lower one drawn up out of the
hasps or sockets on those parts of the building above and below the door to which
the latter is hung and thus the door is unbolted. From the foregoin it is
obvious that by returning the handle or lever to the horizontal position the effect
would be to bolt the door again.
The end of the handle or lever aforesaid which is grasped by the operator is bent
outwardly from the door a distance sufficient to prevent the hand of the operator
being injured by contact with the door.
The locking arrangement before described can be fitted to any pair of doors as
well as to one only irrespective of height thus dispensing with the long monkey-
tail top bolt and stock lock now in use and consequently saving considerable
expense.
Where the device is employed for securing a pair of doors which meet at the
centre it is attached to the lock rail of one of the doors and care must be taken to
attach it to that one of the pair which is intended to be closed last when the lock-
ing operation is from the inside and to the front of the first closed door if it is
desirable to lock from the outside.

I, JOHN THOMAS, of Castle Cary, Somerset, Builder and Contractor, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
.
"This invention relates to improvements in bolts and locks for doors and the like
and has for its object to provide an inexpensive and simple locking arrangement
whereby doors can be fastened more expeditiously than was heretofore possible.
In carrying my invention into practice I screw or otherwise attach upon a con-
venient part of the door, for instance, to be locked, a plate of wrought iron or
other suitable material, to the centre of which I pivot (at a point near one of its
ends) a handle or lever which passes along the lock rail of the door and is capable
of being secured in position upon the same by means of a hinged clip pivotted
to the said handle or lever in combination with a staple fixed on the door, and
an extraneous padlock.
To the pivotted end of this handle or lever I pivot, one on each side of the said
handle pivot, longitudinally and equidistant from said pivot, two bars of metal
or other suitable material constituting bolts, which pass upwardly and down-
wardly, respectively, through the usual guides on the door and then into hasps
or sockets above and below the door, when the handle or lever aforesaid is in a
horizontal or locked position.
These bars of metal aforesaid (hereafter to be termed bolts) are bent inwardly
at their pivotal ends so as to be in a vertical line one with the other.
In operation when the handle or lever aforesaid is raised out of the horizontal
position the upper bolt is drawn down and the lower one drawn up out of the
hasps or sockets on those parts of the building above and below the door to which
the latter is hung and thus the door is unbolted. From the foregoing it is
obvious that by returning the handle or lever aforesaid to the horizontal position
the effect would be to bolt the door again.
The end of the handle or lever aforesaid which is grasped by the operator is bent
outwardly from the door a distance sufficient to prevent the hand of the operator
being injured by contact with the door.
In order that this my said invention may be the more readily understood and
carried into practical effect, reference is hereby made to the accompanying sheet
of illustrative drawings, wherein in Fig. 1 is illustrated a single door with my
locking apparatus in its in-operative position, the locked position being indicated
by dotted lines, while in Fig. 2 is shewn a pair of doors with my locking apparatus
in its operative position.
Referring to the drawings, in which like letters of reference indicate like parts
throughout, a is the handle or lever pivotted at 6 to the door c.
dd are the bolts pivotted at their curved ends dd to the end of the said
handle, the free ends of such bolts passing through guides e upon the door,
and shooting into sockets or hasps f situated upon the jamb and floor, or in other
suitable positions. The end a² of the handle or lever a is bent outwardly as at a³,
so as to prevent the hand of the operator coming in contact with the door when
locking or unlocking the latter. F is the clip for locking the lever a, in con-
junction with a suitable padlock and staple (not shewn).
The locking arrangement before described can be fitted to any pair of doors as
well as to one only, irrespective of height, thus dispensing with the long monkey
tail top bolt and stock lock now in use, and consequently saving considerable
expense.

page_text: Where the device is employed for securing a pair of doors which meet at the
centre it is attached to the lock rail of one of the doors and care must be taken to
attach it to that one of the pair which is intended to be closed last when the lock-
ing operation is from the outside and to the back of the first closed door if it is
desirable to lock from the inside.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
-
•
1. In bolting and locking apparatus for doors and the like, the duplicate bolts
having each a curved end and a straight end, in combination with a pivotted lever
having a raised handle, substantially as specified and shewn.
2. In bolting and locking apparatus for doors and the like, the bolts d, d¹
pivotted at their curved ends to one end of a lever a, and having their free ends
travelling through guides c to take into suitable hasps in the door frame or floor,
substantially as and for the purpose described and illustrated.
