IMPROVE- MENTS IN THE MEANS OR APPARATUS EMPLOYED FOR UNFASTENING CARRIAGE DOORS
Year: 1877

page_text: LETTERS PATENT to Samuel Firth, of Burley, and Joseph Kaye, of Kirkstall,
both near Leeds, in the County of York, for the Invention of "IMPROVE-
MENTS IN THE MEANS OR APPARATUS EMPLOYED FOR UNFASTENING CARRIAGE
DOORS."
Scaled the 1st September 1877, and dated the 7th March 1877.
PROVISIONAL SPECIFICATION left by the said Samuel Firth and Joseph
Kaye at the Office of the Commissioners of Patents on the 7th March 1877.
SAMUEL FIRTH, of Burley, and JOSEPH KAYE, of Kirkstall, both near Leeds, in
the County of York. "IMPROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED FOR
UNFASTENING CARRIAGE DOORS."
Our improvements have particular reference to a Patent obtained by Joseph Kaye,
dated June 4th 1875, No. 2058, entitled " Improvements in the Means or Apparatus
for Detecting the Fastening of Railway Carriage and other Doors; also for Fastening
the same."
Our improvements are also applicable to carriage doors having fasteners of other
descriptions.
The object of our Invention is to provide a ready and safe means whereby
carriage doors may be unfastened at a convenient position in the interior of the
carriage.
For the above purpose we apply an intermediate arrangement of cords, chains,
pulleys, levers, or their equivalents, through which we form a suitable connection
between the door fastener and a handle, or its equivalent, provided in a convenient
position in the interior of the carriage and out of the reach of children. Thus as
applied to the aforesaid handle patented by Joseph Kaye, a rod may be connected
thereto, and pass up along the outside of the carriage door, and its upper end jointed
to a lever on a spindle, the inner end of which is fitted with another lever, which
can be actuated from the inside of the carriage by means of a cord.
We also apply, when required, in connection with the above a dial arrangement,
which shows to the occupants of the carriage whether the door is properly closed
and fastened.

SAMUEL FIRTH, of Birley, and JOSEPH KAYE, of Kirkstall, both near Leeds, in
the County of York. IMPROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED FOR
UNFASTENING CARRIAGE DOORS."
Our improvements have particular reference to a Patent obtained by Joseph Kaye,
dated June 4th 1875, No. 2058, entitled "Improvements in the Means or Apparatus
for Detecting the Fastening of Railway Carriage and other Doors; also for Fastening
the same."
Our improvements are also applicable to carriage doors having fasteners of other
descriptions.
The object of our Invention is to provide a ready and safe means whereby
carriage doors may be conveniently unfastened from the interior of the carriage.
For the above purpose we apply an intermediate arrangement of cords, chains,
pulleys, levers, or their equivalents, through which we form a suitable connection
between the door fastener and a handle or its equivalent, provided in a convenient
position in the interior of the carriage and out of the reach of children. Thus, as
applied to the aforesaid handle patented by Joseph Kaye, a rod may be connected
thereto, and pass up along the outside of the carriage door, and its upper end jointed
to a lever on a spindle, the inner end of which is fitted with another lever, which
can be actuated from the inside of the carriage by means of a cord.
We also apply, when required, in connection with the above a dial arrangement,
which shews to the occupants of the carriage whether the door is properly closed
and fastened.
And in order that our Invention may be more completely understood, reference
is given to the accompanying Drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Figure 1 represents a front elevation; Figure 2, a side elevation of one arrange-
ment of our Invention.
Figures 3 and 4 are respectively a front elevation and plan of another arrange-
ment of the same.
Figure 5 is a side elevation of our Invention, as applied to ordinary carriage
door fasteners, and Figure 6, a front elevation of the same.
Figure 7 shews the inner side of a door with index applied.
a, Figures 1 and 2, is a door fastener arranged in a similar manner to that
described in the Specification of a Patent obtained by Joseph Kaye, dated June 4th
1875, No. 2058; 6 is an arm on the lever or handle c; this is coupled to a vertical
rod d, which is, by preference, let into the door, as shewn, or may be carried along
the exterior thereof; it is supported in the bearings e. This rod & is provided with
a knob or handle f. In order to unfasten the door we press downwards the handle
'or knob f, which, by causing a downward movement of the rod d, raises the handle
or lever c, by which means the latch or bolt is removed from the catch on the door
frame; this being done the door may be opened. A spiral spring (or it may be any
other suitable spring) is applied to take the weight of rod and lever, to prevent the
door from unfastening by their weight.
Another arrangement is shewn at Figures 3 and 4. In this case we attach to
the rod d the lever g, which is provided with the fulcrum bearing h. It will be
readily understood that by pressing or pulling down the lever g, which may be done
by taking hold of a cord or bell pull, or by a ring or other contrivance attached to
the said lever, the same result is effected as described for Figures 1 and 2.
Besides the above, other lever, rod, or cord arrangements may be employed for
unfastening carriage doors, and such arrangements may be applied to other door
fasteners with slight modifications.

page_text: Figures 5 and 6 shew our improvements as applied to carriage door fasteners of
ordinary construction. In this instance the rod d is actuated by a lever i mounted
in suitable fulcrum bearings j; the bottom end of the rod is coupled to an arm or
lever attached to the spindle of the ordinary handle m. It will be readily
understood that by pulling down the lever the arm or lever & is lifted, by which
means the spindle is caused to revolve, thereby relieving the latch o from the catch
on the door frame, this being done the door may be opened.
Figure 7 shows the inner side of a carriage door constructed as described with
reference to Figures 3 and 4. g is the lover which is used for unfastening the door
handle; it is shown in full lines in the raised position, that is, the door being shut,
and in dotted lines in the lowered position, that is, the door being open. The words
"door shut" and "door open," or other suitable index words or signs indicate the
position of the door handle. The door handle may be unfastened from any con-
venient point within the carriage, a connection being made between it and the door
unfastened by means of chains, cords, pulleys, levers, or other equivalents.
Having now described the nature of our said Invention, and shewn by Drawings
how the same may be carried into practice, we would have it understood that
we do not limit ourselves to the exact details or configuration of the parts we have
explained and shewn, as the same may of course be varied or modified without
in any way departing from the nature of our said Invention, but what we do claim
as our Improvements in the Means or Apparatus employed for Unfastening
Carriage Doors" is,—
"
Firstly. The employment of rods and levers, or other equivalent intermediate
gear for unfastening carriage doors from some interior part of the carriage out of the
reach of children, and other than directly at the door handle itself, all substantially
as herein set forth.
Secondly. The application in combination with the means set forth in the first
claim of index appliances in the interior of the carriage for indicating at a glance
whether the door is secured or not.
In witness whereof, we, the said Samuel Firth and Joseph Kaye, have hereunto
set our hands and seals, this Twenty-eighth day of August, in the year of our
Lord One thousand eight hundred and seventy-seven.
