COMPLETE SPECIFICATION.
Improvements in Latches, Looks, or Fastenings for the Doors of
Carriages, and other purposes.
We, JAMES ASTBURY of Windmill Street Walsall in the County of Stafford,
Brass and Iron Founder and HENRY VINCENT of 27 Bath Street, Walsall,.
aforesaid Patternmaker do hereby declare the nature of our said invention and in
what manner the same is to be performed to be particularly described and.
ascertained in and by the following statement:-
Our invention has for its object improvements in latches locks or fastenings for
the doors of carriages and other purposes by which great security is obtained
against the fastening becoming loosened or undone by jarring or shocks such as.
traps and vehicles are subject to on roads.
In order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto a double sized sheet of drawings
upon which we have illustrated one example of our fastening and its application.
but it will be understood that general configuration and desig i may be considerably.
varied without departing from the nature of the invention.
Figure 1 is a front elevation of a broken off carriage door A and broken,
off bar B with my fastening composed of the main parts E and K attached
thereto.
Figure 2 is a section through A and B giving a plan of the fastening in its locked
position but with the part e broken off short.
Figure 3 is a front elevation of the fastening fixed ou the parts A and B and with.
the plate e in position but unlocked.
Figure 4 is a sectional plan through the centre of the fastening.
Figure 5 is an enlarged section through the portion K.
Figure 6 is a plan of the part K.
Figure 7 is a perspective view of the portion K showing a clearer view of the
locking bolt kt.
Figure 8 is a broken off back view of the locking lever latch showing the
countersunk part to receive the point of the locking bolt and the rounded
edges or corners e7 and 8 to enable the latch e' to pass over the bolt k*.
Figure 9 is an enlarged part section of K through the centre showing the locking.
bolt in plan with an alternative method of giving spring to the bolt.
On the accompanying A is the door of a vehicle and B is the bar of a frame in.
which the door A fits. The part E of the fastening is secured or fastened to the.
door A and the other portion K of the fastening is similarly fastened to the frame
or bar B. The portion K may be made with a flat plate or an angular one as.
shown having the front portion K and the wing plate . In any case a such like.
nose piece or staple rounded in all directions is provided with the undercut.
slot or gap and the base has the locking bolt mounted upon any suitable
spring such as which is rubber or any other suitable spring such as S shown at.
Figure 9.
The portion E of the fastening is composed of a suitable plate E of any desired
design or configuration with the extension plate e' one with the same this extension,
plate has a hole e cut through so that the plate passes over the rounded head or
staple of the upper portion of the fastening K. Upon the plate E is pivotted
the arm working upon the pivot e³. This arm carries the nose or latch,
D

page_text: piece which is formed at the back with the countersunk recess e and the rounded
ends 7 and 8.
The action is as follows:-
The door is shut upon K when the fastening E is in the position shown by
Figure 3, that is to say the arm e and latch e' are turned on one side as shown.
To lock the fastening it is only necessary to turn the arm downwards when the
latch passes over the spring locking bolt pressing it back so that when in its
locked position, as seen at Figures 12 and 4 the spring bolt is in the countersunk
recess e as seen in section at Figure 4. To unlock the fastening it is only
'necessary to lift or turn round the lever e when the bolt is forced back and the
fastening is brought to the position as seen at Figure 3.
The fastenings may be made of any metal according to the purpose to which
they are to be used and of course may be applied to a door, lid, etc., hung in any
position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1st. The improvements, in latches, locks, or fastenings for the doors of carriages
and other purposes consisting of the portions E and K working in combination,
the one with the other and with the supplemental parts substantially as and for the
purpose herein set forth and shown upon the drawings.
2nd. In carriage door fastenings the plate E, with its prolongation & and e and
lever with its nose piece e' working in combination with a such-like plate as K
substantially as set forth and showu upon the drawings.
3rd. The carriage or other door fastening herein set forth and illustrated by
Figures 1 to 9 upon the accompanying sheet of drawings.
Dated this 6th day of February 1896.
