COMPLETE SPECIFICATION.
Improvements in Latches or Fastenings for Road Vehicle and other
Tailboards and Doors.
I, JAMES ASTBURY of Windmill Street Walsall in the County of Stafford
Brass and Iron Founder 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:-
My invention has for its object improvements in locks or latches for carriage
traps and other similar doors which are so designed as to be exceeding simple
in their construction and easy to manufacture with the detailed parts so designed
and constructed as not to be liable to be broken or deranged under very heavy
wear.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a sheet of drawings upon which
I have illustrated the same, but it will be understood that the general configura-
tion and design may be considerably varied without departing from the principle of
the invention.
Figure 1 is a front elevation showing the two portions brought together which
constitute my complete lock or latch or door fastening.
Figure 2 is a section plan of the same on the line 1, 2.
Figure 3 is a side view of the main or lock portion A of the fastening.
Figure 4 is a side view of the smaller or staple portion B of my new fastening.
Figure 5 is the casing A of the lock portion with a removed.
Figure 6 is a cross section through the latch a¹.
My new trap or carriage door fastening consists of two main portions viz., the
lock front A and the staple portion B and they fasten together as seen at Figure 1
in front elevation and Figure 2 in plan.
The A or lock portion is constructed from a main casting or stamping as seen
opened out at Figure 5 with its projecting flange as a and back flange a and
which when the bolt or latch a' has been mounted inside is covered over by the
cover plate a which is fastened down by screws or rivets such as a'.
The latch or bolt a is secured upon the pivot bolt E by the nut and it is
maintained in its closed and normal position by the spring S which is shown in dotted
lines at Figures 1 and 3. It will be observed that the latch or bolt a¹ has a lower
portion a' which is used in lifting the bolt or latch when it is desired to open the
fastening and the end is also provided with the spur at which adds to the security
and stability of the fastening. The flange a with the screw hole a" adds
considerably to the security of the whole when fastened to the edge of the
door.
The staple B simply consists of the one plate with the nose piece 6' notched at 6*
which is the usual forn of latch plate and to which in itself I lay not exclusive or
special claim.
These locks may be fixed one to the middle of the tail board of a carriage or
one on each side, but the principle is the same in either case. They may be made
from castings or stampings, or partly one and partly the other and from any
suitable metal but generally from brass.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improvements in the locks or latches for carriages, traps and other similar
doors consisting of the lock A with its latch a hung upon its pirot E and kept in its
closed and normal position by any suitable spring S and operating in combination
with the staple B substantially as and for the purpose herein set forth and as
shown upon the drawings by Figures 1 to 6 inclusive."
Dated this 15th day of August 1896.
