PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Securing Cart,
Waggon, and other Doors.
I, JOSEPH KAYE, of South Accommodation Road, 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 the Patent granted to me
No. 3572 dated March 19th, 1885, and has for its object the arrangement and
combination of the apparatus in such a manner that, the lever by which the
fastening is effected may be more effectually retained in the "open
positions by a simple and antomatic arrangement.
"
or "shut"
I accomplish my object in the following manner-To each side of a cart or
waggon frame is secured a slotted bar, between the projections of which is
mounted on a fulcrum pin, a curved lever by which the cart, waggon or other door
is secured.
In the slotted bar at right angles to the fulcrum pin is bored a hole some distance
into the bar, into which is placed a piston rod and spiral spring, the former being
so constructed that on pushing the rod towards the bottom of the hole, the spiral
spring is compressed, so that on mounting the curved lever in the slotted bar, the
end of the piston rod is forced by the compressed spring against the flat portion
of the curved lever, thus retaining it in the position in which it may be placed;
and by forming a portion of the curved lever flat in the position so that when the
door is closed and secured by the lever, the end of the piston rod will engage with
the flat portion and thus effectually retain the lever in the position for securing the
door and when the lever is moved into the position for the door to be opened,
the end of the piston rod presses against the lever thus keeping it firm on the
fulcrum pin.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Securing Cart,
Waggon, and other Doors.
1, JOSEPH KAYE, of South Accommodation Road, 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 to the Patent granted to me
No. 3572 dated March 19th 1885, and has for its object, the arrangement and
combination of the apparatus in such a manner that, the lever by which the fastening
is effected, may be more effectually retained in the "open" and "shut" positions
by a simple and automatic arrangement.
In the accompanying drawings
Fig. 1 represents a portion of a waggon having the door fitted with my improved
fastner.
Fig. 2 is an enlarged side view of a portion of a door with my improved fastner
in position for securing the door.
Fig. 3 a front view of the same.

page_text: Fig. 4 a side view showing the fastner lever in position for allowing the door to
be opened.
Fig. 5 a plan of the forked har to which the lever is accured.
Fig. 6 a view partly in section, of the curved lever removed from the forked bar
or supporting joint, and
Fig. 7 an enlarged sectional view of the joint showing the piston rod and spiral
spring.
To each side of a cart or waggon frame is secured a forked bar A. between the
projections of which is mounted on a fulcrum pin B. a curved lever C. by which
the cart, waggon or other door is secured.
In order to maintain the lever C. in a horizontal or other desired position, a
hole is bored through the said lever, into which are placed two short bars E. having
circular heads formed thereon, between which is compressed a spiral spring (. by
which the heads are pressed outwards against the inner surfaces of the forked
bar A. and when the curved lever C. is in position for securing the door when
closed, the heads of the short bars E. E. engage with indentations F. F. formed on
the inner surface of the forked bar A. thereby securing the lever in position.
In order to give more rigidity to the curved lever C. and thereby add to the
security of the fastening, I bore in the forked bar A. at right angles to the fulcrum
pin 13. a hole some distance into the bar, into which is placed a piston rod II. aud
spiral spring S. the former being reduced in diameter for some portion of its length,
to receive the spiral spring S. thereon, so that, on pushing the piston rod towards
the bottom of the hole, the spiral spring is compressed.
On mounting the lever C. in the forked bar A. the end of the piston rod 11. is
forced by the compressed spiral spring S. against the said lever thus assisting the
before mentioned short bars E. E. to retain the lever in the position, in which it
may be placed, and by forming a portion of the curved lever flat or concave at J.
so that when the door is closed and secured by the lever C. the end of the piston
rod 1. engages with the flat or concave portion J. and thus in conjunction with
the side bars E. E. effectually retain the lever in the position for securing the door.
When the lever is moved into the position for the door to be opened, the end of
the piston rod H. pressing against the lever and the heads of the two side bars E. E.
engaging with the indentations K. K. formed on the inside of forked bar A. the
lever is retained firm on the fulcrum pin.
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 parts forming the complete apparatus arranged sub-
stantially as and for the purpose set forth and illustrated by the accompanying
drawings.
2. The combination of the forked bar A. curved lever C. piston rod H. and
spiral spring S. arranged substantially as and for the purpose set forth and illus-
trated by the accompanying drawings.
Dated this 9th day of June 1891.
