Year: 1875

page_text: LETTERS PATENT to Joseph Kaye, of Kirkstall, near Leeds, in the
County of York, for the Invention of "IMPROVEMENTS IN THE MEANS
OR APPARATUS FOR DETECTING THE FASTENING OF RAILWAY CARRIAGE AND
OTHER DOORS, ALSO FOR FASTENING THE SAME.'
"
Sealed the 21st August 1875, and dated the 4th June 1875.
PROVISIONAL SPECIFICATION left by the said Joseph Kaye at the
Office of the Commissioners of Patents, with his Petition, on the
4th June 1875.
I, JOSEPH KAYE, of Kirkstall, near Leeds, in the County of York,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE MEANS OR APPARATUS FOR DETECTING THE FASTENING OF RAILWAY
CARRIAGE AND OTHER DOORS, ALSO FOR FASTENING THE SAME," to be as
follows:-
My Invention consists of an arrangement of door fastener, which is
applicable particularly to railway carriage doors, providing a ready
method of securely fastening the doors to and opening the same; but
more particularly a means of detecting at a great distance whether the
door is entirely closed and fastened.

page_text: This Invention is also applicable to other doors, and is as hereafter
described.
On the framework forming the doorway, and in a convenient position
thereon, is provided a catch, and on the door is mounted in suitable
bearings a lever or handle. A cam is provided on the same shaft, or
attached to the lever or handle; this cam retains the lever or handle
in a position at right angles to or sticking out from the door by means of
a spring attachment or its equivalent, and is liberated only when the
door is perfectly closed. When' the door is closed this spring attach-
ment by means of a set screw or other equivalent on the framework of
the doorway is relieved from the cam and allows the handle to drop, at
the same time causes a stud or projection which is attached to the lever
or handle to pass behind the catch or the doorway frame, and thereby
keeps the door firmly closed.
By the levers or handles projecting out when the doors are not
perfectly closed and fastened those in attendance at railway stations
and other places will much more readily detect them than when the
ordinary fastener and handle are used, at the same time a self-acting
andsafe door fastener is provided.
When preferred the lever and parts connected therewith may be fixed
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Joseph Kaye in the Great Seal Patent Office on
the 4th December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
KAYE, of Kirkstall, near Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria by Her
Letters Patent, bearing date the Fourth day of June, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Kaye, Her special licence
that I, the said Joseph Kaye, my executors, administrators, and
assigns, or such others as I, the said Joseph Kaye, my executors,

page_text: administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN THE MEANS OR APPARATUS FOR DETECTING THE FASTENING OF RAILWAY
CARRIAGE AND OTHER DOORS, ALSO FOR FASTENING THE SAME," upon the con-
dition (amongst others) that I, the said Joseph Kaye, my executors
or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calender months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Kaye, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying two
Sheets of Drawings and marks thereon, that is to say :-
My Invention consists of an arrangement of door fastener which is
applicable particularly to railway carriage doors, providing a ready
method of securely fastening the doors and opening the same, but more
particularly a means of detecting at a great distance whether the door
is entirely closed and fastened.
This Invention is also applicable to other doors, and is as hereafter
described.
On the framework forming the doorway, and in a convenient position.
thereon, is provided a catch, and on the door is mounted in suitable
bearings a lever or handle. A cam is provided on the same shaft, or
attached to the lever or handle; this cam retains the lever or handle in
a position at right angles to or sticking out from the door by means of
a spring attachment, or its equivalent, and is liberated only when the
door is perfectly closed. When the door is closed this spring attachment
by means of a set screw or other equivalent on the framework of the
doorway is relieved from the cam and allows the handle to drop, at the
same time causes a stud or projection which is attached to the lever or
'

page_text: door. The lever or handle a is retained at right angles by the pawlf
until the door is closed, when the pawlf is pushed from under the pro-
jecting part e by means of the catch g, or its equivalent, shewn at Figs.
4 and 5, which catch g, or its equivalent is fixed on the framework of
the doorway. The pawl f is brought into position by means of the
spring or spiral spring h¹, or their equivalent. At Figs. 2 and 3 i is a
plate or cover for enclosing the working parts, through which also the
apparatus is secured. The pawl f is mounted on a pin fl on the
foundation plate d. On the plate ƒ being removed from under the
projecting part c the handle or lever a falls into the position shewn in
dotted lines at a¹, bringing the cam c into the position shewn at Fig. 4
over the catch g, when in this position the door is securely fastened and
cannot be opened without lifting the lever or handle a to the position a,
shewn at Figs. 1, 2, and 3; in this position the cam c is turned clear
of the catch g into the position shewn at c¹, Fig. 4, when in this
position the door without difficulty can be thrown open. In order to
lock the catch arrangement I provide in suitable bearings j a bolt k;
this bolt k is brought into operation by means of a key inserted into
the hole ; on turning the key one way or the other the lever or pro-
jection m causes the bolt k to move backwards or forwards. The end
of the bolt k can by this arrangement when the lever or handle a is in
the position shewn at a¹ be passed into the hole 1, thereby retaining the
cam c in the position shewn at c, Fig. 4, preventing the door being
opened until the bolt k is withdrawn. By the levers or handles a pro-
jecting out when the doors are not perfectly closed and fastened those
in attendance at railway stations and other places will much more
readily detect them than when the ordinary fastener and handle are
used, at the same time a self-acting and safe door fastener is provided.
When preferred the lever or handle a and parts connected therewith
may be fixed on the framework of the doorway, and the catch g fixed
on the door.
When the lever or handle a has fallen into the position shewn in
dotted lines at a¹, Fig. 1, Sheet 1, the slot r or opening in the cover i
is provided with any convenient self-acting cover; this is made so as to
fall over the slot or opening as the handle or lever a drops.
Fig. 6 shews the exterior of a railway carriage, and shewing the
annlication of the berein-hefore described fastener to the doors thereof

page_text: It will be seen that the handle or lever at n has a similar appearance
to the handle ordinarily used, and may also be placed in a similar
position on the doors, as shown; but I would here remark that the
lever or handle n may be of any convenient form.
At one operation of pulling the lever or handle n not only is the
catch g relieved from the cam c, but by continuing to pull in the same
direction the door may be opened.
On Sheet 2 Figs. 1, 2, and 3 shew respectively a side elevation, a
front elevation, and plan of a modification of my Invention; Fig. 4
shews the application of this modification to tramway car doors or other
doors. In this arrangement in suitable bearings a on a foundation
plate 6 I provide the shaft c, on which is mounted a cam d, which may
be of a similar construction to that described on Sheet 1. On the outer
ends of the shaft c (which I by preference make square at c¹) I mount
the handles e and f, the smaller being for interior and the larger for
exterior use. When the levers or handles e and ƒ are in the position,
as shown at Fig. 2, the pawl g retains them in that position by passing
under the projecting part h; the pawl g is kept in position by means of
the springs i, or their equivalents, and fitted on to the plate b in the
same manner as described on Sheet 1; also I employ a catch j, which
is fixed on the framework of the doorway of the vehicle, and is of a
similar character to that shewn at Figs. 4 and 5, Sheet 1.
On closing
the door the catch j removes the pawl g from under the projecting
part h, when the handles e and ƒ immediately drop and bring the cam
in a similar position (with regard to the catch j) to that shewn at
Fig. 4, Sheet 1. When in this position the door is held firmly closed
and cannot be opened until the handles e and fare raised into the
position shewn at Fig. 2. The cam and pawl 9 are enclosed by means
of a cover k. In Fig. 2 I have shewn the cover k removed for the
purpose of more clearly shewing the interior arrangement.
Fig. 4 shews the mode of applying my Invention to vehicles having
sliding doors, and representing the door closed and the handle / down,
in which position of the handle the door is closed and held fast. At
one operation of pulling the handle 7 not only is the catch relieved from
the cam d but by continuing to pull in the same direction the door may
be slided open. A similar arrangement of apparatus may be applied to
other doors.
