PROVISIONAL SPECIFICATION.
Improvements in Means for Operating Fastenings for Exit and
other Doors.
I, JOSEPH KAYE, of Bank House, Kirkstall, Leeds, in the County of York, Lock
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in Locks and Latches for which
letters patent were granted to me numbered 1643 and dated the 21st day of
April 1880. In the present improvement I construct a fitting of such form as admits
of the opening and shutting of the door by means of a Horizontal or Diagonal bar
which is secured to the door. The improved fitting is formed with a flange which is
secured to the door in the position of the ordinary handle, cast to this flange is a
cylinder of rather more depth than the thickness or diameter of the horizontal or
diagonal bar; both sides of this cylinder are cut away when the bar is continued
beyond the cylinder for the purpose of allowing the horizontal or Diagonal bar to
move freely in the same, surrounding this bar I secure a ball shaped boss the rounded
portion being smaller in diameter than the cylinder in order that the boss may move
freely in the cylindrical part of the fitting; from the under side of this ball shaped
boss passes a projection through the flange of the fitting and terminates in a
head which prevents the ball shaped boss being drawn from the cylinder of the
fitting.
The lock or latch is in the ordinary position and may be of ordinary construction.
In the case of an exit door the head of the projection from the ball shaped boss on
the horizontal or diagonal bar is made to operate the latch.
In the case of swing or ordinary doors the spindle of the latch is secured to the boss
surrounding the bar and secured to a corresponding arrangement on the other side of
the door, in this case the bar terminates in the boss.
Dated this 5th day of October 1888.

COMPLETE SPECIFICATION.
Improvements in Means for Operating Fastenings for Exit and
other Doors.
I, JOSEPH KAYE, of Bank House, Kirkstall, Leeds, in the County of York, Lock
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to certain improvements in locks and latches for which letters
patent were granted to me numbered 1643, dated the 21st day of April 1880.
The improvement is applicable to locks and latches of the class commonly known as
rim, flush and mortice: in the drawings Fig. 1 represents an elevation of such portions
of a pair of folding doors.as are required to explain my improvements, which are
added thereto.
Fig. 2. is a sectional plan of the same.
Fig. 3. is an elevation, and Fig. 4. a sectional plan of a single door showing how
my apparatus may be fitted thereto.
When applying my improvement to folding doors, I mount a bar to each door A.
and A¹ in a horizontal, diagonal, or vertical direction, each bar being supported by
suitable fittings secured to the respective doors.

page_text: The bar B. is attached to the first opening door A. of a pair of folding doors, and is
supported at one end by a fitting C. made to receive the end of the bar; the other end
of the bar next the lock or latch being attached to a boss G. which is supported by a
cylindrical fitting E. having a flange thercon and by which it is secured to the door
in the position of an ordinary handle.
The cylindrical portion of the fitting E. is deeper than the thickness or diameter of
the bar B. and in order to receive the same, both sides of the cylindrical portion of
the fitting are cut away. Surrounding the bar within the fitting E. is secured a
boss G. by preference ball shaped, somewhat less in diameter than the interior of the
cylindrical fitting, the ball shaped boss having an extension G which projects through
the flange of the fitting into the interior of the lock or latch frame, terminating with
a screwed adjustable bar H. having a collar J. thereon, larger in diameter than the
extension G which prevents the ball shaped boss G. and bar B. being drawn away
from the cylindrical fitting.
The adjustable bar H. may be screwed or otherwise secured to the extension or
projection G¹ and may extend to the opposite side of the door as shown, or be cut to
such length that the end is in contact with the curved portion of the lever K. so that
when the bar B. on the inside of the door A. is pressed towards the door, the ball
shaped boss G. is also moved in the same direction until the enlarged portion at G
comes in contact with the bottom of cylindrical fitting E; the adjustable bar H. on the
operation of the bar B. in the direction described actuates the lever K. on its
fulcrum pin, the opposite end of lever moving in the direction of arrow causes the
segment tongue L. to be withdrawn from the striking plate M. secured to the edge
of the second opening door A¹.
Should it be required for the doors to open from both sides, the adjustable bar H.
is extended to the outside of the door as shown, a similar extension being also
connected to the ball shaped boss in cylindrical fitting E' each extension terminating
with a handle or knob, or a bar B. having similar fittings; but if required to open
from the inside only, the adjustable bars H. in either door do not extend through
the same, but one is cut to such length as to be in contact with the end of lever K. as
shown by Fig. 4.
In order that the doors may be opened by pressing at the bar B mounted to the
door A¹ the bar B. on door A. is extended for some distance beyond the cylindrical
fitting E. the end of the bar B. by preference terminating in an acute angle with
the axis of the same. On the door A¹ the bar B' is mounted in a similar manner
as on door A. and the ball shaped boss G. may be retained in the cylindrical
fitting E. by a screw and collar J. as before described, or by a screw N. screwed into
the end of projection as shown; the screw being extended to the outside of the door
should it be required to open the door from both sides, or if from one only to
terminate as shown on drawing.
It will be obvious that on pressure being put on the bar "B₁, of, door A¹ in the
direction of arrow, 'the angular end of bar will cause the bar 'B.. on door A. to
move in the same direction, and thereby to operate the lever K. and segment
tongue L. that the latter is withdrawn from the striking plate "M. and 'the doors
liberated.
In order that the folding doors A. and A' may be automatically latched or secured
so that the same cannot be opened without the operation of one or both bars in the
inanner, described ; the first folding door Alemay be fitted with automatic bolts or
latches similar to those fully described in my specification numbered -7455, idated
3rd June 1886, which are liberated on the opening of the first folding door A.
از
When applying my invention to single doors; the bar B.-is-mounted-in the manner
as before described, but does not extend beyond the cylindrical fitting: E. the
extension of ball shaped boss G. terminating with an adjustable bar H. and collar J.
the former for operating the lever K. and segment: tongue L. for liberating the
door in the manner as before described.
In the case of swing doors, I secure a latch in each door A. and A¹and mount the

page_text: bars B. and B' in a similar manner as before described, and shown by Fig. 5. which
represents a sectional plan of a pair of swing doors made to open in opposite directions
as shown by curved arrows.
To the extension of each ball shaped boss G. is secured an adjustable bar H. of
such length as to be in contact with the curved end of its respective lever K. s0
that on the operation of either bar B. or B' the segment tongue L. in connection
therewith will be operated and the door allowed to be opened.
The sectional detail Fig. 5. illustrates an arrangement by which one or both of the
segment tongues L. may be adjusted, so that they may be regulated to retain
sufficient hold of each other should either door shrink. According to this arrange-
ment I prefer to mount one of the latch segment tongues in a frame P. made to slide
in the socket or frame Q. which is secured to one of the doors, the lever K. being
mounted on a fulcrum pin the same as in a frame of the ordinary description.
On one of the sides of the frame P. is formed a lug R. through which passes
a screw S. having a collar T. secured at the back of the flange of frame Q. the head of
the screw being recessed in the said flange as shown, so that on operating the screw,
the frame P. and segment tongue L. are adjusted to the required position that the
tongues have sufficient hold for keeping the doors closed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of one or more bars B. with a lever K. segment tongue L. and
striking plate M. substantially in the manner and for the purpose described.
2. The combination of one or more bars B. and B' with a lever K. segment tongue L.
and striking plate M. substantially in the manner and for the purpose described.
3. The combination of the bar B. with the lever K. segment tongue L. and
adjustable frame P. substantially in the manner set forth.
4. The method of securing swing doors by the segment tongue L. of one door
acting as the striking plate to the segment tongue of the other door substantially in
the manner as shown and described.
Dated this 5th day of July 1889.
