Improvements in and connected with Hinges for the Doors of
Dog-carts and like Vehicles.
We, ALFRED HARRY DAVIES, and WILLIAM DAVIES, trading together as
John Preece & Sons, of Borough Carriage Works, 43, Wolverhampton Street,
Dudley, Worcestershire, Carriage Builders, do hereby declare the nature of this
invention to be as follows:-
This invention has reference to the hinges of the doors of dog-carts and like
vehicles which doors are constructed to open down and fix at a certain angle to
form a foot board for the occupants of the back of the vehicle and are also
sometimes required to turn right down and hang vertically. It is at present
customary to employ side chains for maintaining the door in the said inclined
position. By our invention as hereindescribed we so construct the said hinges
with a removeable bolt or stop as to maintain the said door in the required
inclined position without using any side chains and so as to enable the door to be
readily turned down into the said vertical position when desired.
Each of the said hinges consists of two parts jointed together. One of these
parts which we call the moveable part is fixed to the door and moves with it and
the other part which is stationary is fixed to the underside of the back of the floor
of the dog-cart or other like vehicle.
According to one arrangement of carrying out this invention the moveable part
of each of the hinges has a projecting heel or lump formed near the joint. The
fixed part of the hinge is so shaped that this heel or lump does not come in contact
therewith however far the door may be turned down. Between the two hinges or
otherwise adjacent thereto we provide a bolt or stop which may consist of a 'metal
bar free to be turned or be otherwise moved in bearings fixed to the underside of
the bottom of the vehicle. The ends of this bar are near the hinges and the said
ends are or may be cranked, so that when the said bar is turned in one direction
the cranked ends thereof come against the fixed parts of the hinges. If the door
is now opened and turned down to its required angular position to form a foot rest,
the heels or lumps of the moveable parts of the hinges will cramp the ends of the
bar or bolt against the fixed parts of the hinges and the said bolt ends will thus
form stops and maintain the moveable parts of the hinges and the door in the
required angular position. The heels may be notched or have holes where they
come in contact with the bolt ends so as the better to prevent the bolt shaking out
of place.
When the said bar or bolt is turned so as to turn its cranked ends away from the
fixed parts of the hinges then as there are no obstructions to the heels the door can
be turned right down into a vertical position.
Instead of the said bar or bolt being made to turn as above described to stop or
release the hinges the said bar or bolt may for the same purposes be arranged to
be moved end wise or there may be a separate stop bolt for each hinge.
Instead of a heel being formed on the moveable part of each of the hinges to
cramp the stop bolt against the fixed part as above described this heel may be
dispensed with and the stationary part of the hinge may project beyond the joint
for the stop bolt to come into contact with, the stop bolt being so arranged as to
form a stop for the moveable part of the hinge and maintain it in its required
inclined position.

Improvements in and connected with Hinges for the Doors of
Dog-carts and like Vehicles.
We, ALFRED HARRY DAVIES, and WILLIAM DAVIES, trading together as
John Preece & Sons, of Borough Carriage Works, 43, Wolverhampton Street,
Dudley, Worcestershire, Carriage Builders, 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 has reference to the hinges of the doors of dog-carts and like
vehicles which doors are constructed to open down and fix at a certain angle to
form a foot board for the occupants of the back of the vehicle and are also
sometimes required to turn right down and hang vertically. It is at present
customary to employ side chains for maintaining the door in the said inclined
position. By our invention as herein described we so construct the said hinges
with a removable bolt or stop as to maintain the said door in the required
inclined position without using any side chains and so as to enable the door to be'
readily turned down into the said vertical position when desired.
We will describe this invention by referring to the accompanying sheets of
drawings on which
Figs. 1 and 2 are general views of a dog cart body and door with our invention
applied the door being shewn in Fig. 1 in its angular position to form a foot rest
and in Fig. 2 the door is shewn turned down;
Fig. 3 is a sectional elevation of part of the same shewing the hinge with its
locking bolt or stop on an enlarged scale the door being in its angular position and
Fig. 4 shews the same parts as Fig. 3 with the door turned down;
Fig. 5 is a front elevation and plan of the locking bolt or stop drawn to the same
scale as Figs. 3 and 4;
Figs. 6 and 7 are inverted plans of part of the dog cart body door and hinges
illustrating a modified form of the locking bolt or stop and
Figs. 8 and 9 illustrate a further modification of our invention.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
Referring firstly more particularly to Figs. 1, 2, 3, 4, and 5 it will be seen that
there are two hinges connecting the door A to the bottom B of the dog-cart. Each
of these hinges consists of two parts jointed together one of these parts marked C
which we call the moveable part is fixed to the door A and moves with it and the
other part marked D which is stationary is fixed to the underside of the back of
the floor B of the dog-cart or other vehicle to which our invention is applied.
In this arrangement of our invention the moveable part C of each of the hinges
has a projecting heel or lump c¹ formed near the joint pin e which connects the
movable part C to the fixed part D the latter being formed with downwardly
projecting ears d₁ d between which the movable part C fits. These ears d² d²
project down so far that the heel or lump c' does not come in contact with the
base of the stationary part D however far the door A may be turned down, as
will be seen by Figs. 2 and 4 where the door is shewn turned down and the heel or
lump has passed between the ears d' d. Between the said two hinges or otherwise
adjacent thereto we provide a bolt or stop F which by preference consists of a
round metal bar of the shape shewn in Fig. 5 free to be turned in bearings g¹ g³
fixed to the underside of the bottom B of the vehicle. In this example of our
invention the bar F is cranked at f' f' near the hinges so that when the bar F is
turned in one direction the cranked parts f'f' come against the ears d' d' of the
fixed parts of the hinges as shewn in Figs. 1 and 3. If the bar A is now opened
and turned down to its required angular position as shewn in Figs. 1 and 3 to form
a foot rest, the. heels or lumps of the movable part C of the hinges will as

page_text: shewn in Figs. 1 and 3 cramp the cranked parts flf of the bar or bolt F against the
ears d' d' of the fixed parts D of the hinges and the said parts ff of the bolt will
thus form stops and maintain the movable parts C of the hinges and the back A in
the required angular position as shewn. The heels c' are by preference notched as
shewn where they come in contact with the parts ff of the bolt so as the better
to prevent the bolt F shaking out of place.
When the said bar or bolt F is as shewn in Figs. 2 and 4 turned so as to turn its
cranked parts ff away from the ears d' d' of the fixed parts D of the hinge then
as there are no obstructions to the heels c¹ the bar A can be turned right down into
a vertical position as shewn in Figs. 2 and 4. One end of the bolt F is turned
upwardly as shewn so as to form a handle for turning the bolt F and when the
bar A is turned up and closed against the back of the dog cart or other vehicle the
door comes into contact with this handle f' and holds it firmly in a notch b' which
we provide in the back of the floor B of the vehicle.
Instead of the bar or bolt F being made to turn as above described with
reference to Figs. 1, 2, 3, 4 and 5 to stop or release the movable parts C of the
hinges the said bar or bolt F may for the same purpose be arranged as shewn in
Figs. 6 and 7 to be moved endwise. In this example it will be seen that there is
no crank at one end of the bottom B but that this part is made straight and that
the main portion of the bolt F is arranged nearer to the joint pin e than in the
arrangement first above described so that when this bolt F is moved end wise in one
direction as shewn in Fig. 6 it forms a stop for the ears c¹ of the movable parts C
to close against and maintain the door in its required angular position and when
the bolt F is moved to its extreme position in the opposite direction as shewn in
Fig. 7 the door A can now be turned down as the ears c¹ will miss the bolt F. It
will be evident also that instead of making the bolt F long enough to serve for
both hinges two separate stop bolts can (without departing from the nature of our
invention) be employed that is to say one stop bolt for each hinge but this would
not be such a convenient arrangement as each stop bolt would have to be moved
independently.
Fig. 8 is a sectional elevation of part of a trap floor door A hinges and stop bolt
and Fig. 9 is an inverted plan of the same illustrating a further modification of this
invention in which instead of a heel c¹ being formed on the movable part C of each
of the hinges to cramp the stop bolt F against the fixed part D of the hinges as
above described this heel is dispensed with and the ears dd of the stationary part
of the hinge are as shewn more clearly in Fig. 8 made to project at d* below the joint
pin e for the stop bolt F to come into contact with; the stop bolt F being arranged
to move endwise as in Figs. 6 and 7 so as to either form as in Figs. 8 and 9 a stop
for the movable part of the hinge and maintain the door A in its required
inclined position or when the bolt F is moved in the opposite direction to occupy
the position shewn in Fig. 7 then the door B being unsupported by the bolt D will
be free to be turned down.
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 :-
1. The hereindescribed improvements in and connected with hinges for the doors
of dog-carts and like, vehicles for supporting the door at a certain angle to form a
footboard and for allowing of the door to turn down and hang vertically when
required, the said improvements consisting in making the movable parts of the said
hinges with a heel or lump such as c¹ and employing therewith a bolt adapted to be
moved so as to either form a stop between the heel or lump and the fixed parts of
the hinges and support the door in the required angular position or to form no
obstruction to the movable part of the hinge and allow of the door being turned
down to hang vertically substantially as hereinbefore described with reference to
Figs. 1, 2, 3, 4, 5, 6 and 7 of the accompanying drawing.
2. The hereindescribed improvements in and connected with hinges for the doors

page_text: of dog-carts and like vehicles for supporting the door at a certain angle to form a
footboard and for allowing of the door to turn down and hang vertically, when
required, the said improvements consisting in making the fixed, parts of the hinges
with a projection such as d' and employing therewith a bolt adapted to be moved so as
to either form a stop between the said projection and the movable parts of the hinges
and support the door in the required angular position or to form no obstruction to
the movable part of the. hinge and allow of the door being turned down to hang
vertically substantially as hereinbefore described with reference to Figs. 8 and 9 of
the accompanying drawing.
