PROVISIONAL SPECIFICATION.
An Improved Catch for the Tail-boards of Dog-oarts and other
Vehicles.
I, JBAIAH CLARk, of 13, Oxford Street, Weston-super-Mare, Coach-builder, do
hereby declare the nature of this invention to be as follows:-
The improved catch for the tail-boards of dog-carts and other vehicles which
constitutes this invention consists of a steel spring bar carrying towards the outer
end a roller around which is a ring or band of india-rubber. The roller is free to
rotate in suitable bearings. The bar is designed to be secured to the sides of
the vehicle as is usual. When in closing, the door is brought into forcible
contact with the rubber-clad roller, the spring bar rises and permits the door to
pass beyond the roller. The bar then resumes its normal position and keeps
the door closed. The provision of the rubber ring or band obviates noise due
to vibration.
To release the door it is drawn back and the catch is raised by contact with the
door in the act of opening.
Under a modification the rubber-clad roller is so arranged as to permit the door
to raise it and pass it in closing, but not in opening. In this arrangement
the catch is opened by raising the spring bar by hand.
Dated this 4th day of October 1893.

COMPLETE SPECIFICATION.
An Improved Catch for the Tail-boards of Dog-carts and other
Vehicles.
I, ISAIAH CLARK, of 13, Oxford Street, Weston-super-Mare, Coach-builder, 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 :-
The improved catch for the tail-boards of dog-carts and other vehicles which
constitutes this invention consists of a steel spring bar carrying towards the outer
end a roller around which is a ring or band of india-rubber. The roller is free to
rotate in suitable bearings. The bar is designed to be secured to the sides of the
vehicle, as is usual. When, in closing, the door is brought into forcible contact with
the rubber-clad roller, the spring bar rises and permits the door to pass beyond the
roller. The bar then resumes its normal position and keeps the door closed. The
provision of the rubber ring or band obviates noise due to vibration.
To release the door it is drawn back, and the catch is raised by contact with the
door in the act of opening.
Under a modification the rubber-clad roller is so arranged as to permit the door
to raise it in closing, but not in opening. In this arrangement the catch is opened
by raising the spring bar by hand.
Referring to the accompanying drawings,
Fig. 1 represents a side view of one form of my improved catch as attached
to the sides a of a dog-cart or other vehicle; it being understood that there is one

page_text: such catch at each side. The tail-board b is shown open. The catch consists of a
steel spring bar c secured, as is usual, by screws or other means towards its inner
end to the sides a of the vehicle.
At its outer end the spring bar c carries a roller d free to rotate on journals e
and encircled by a tightly fitting band or ring f of india-rubber.
When, in closing, the tail-board b is brought into sufficiently forcible contact
with the band or ring the spring bar c yields and is raised carrying up the roller
with it, as seen at Fig. 2.
When the top of the door or tail-board has passed inwards clear of the ring f
the bar c rebounds to its normal position and the tail-board is retained closed by
the roller as seen at Fig. 3. The tail-board is released by being forcibly pulled
back and so raising the rubber-encircled roller, the action being the saine as
in closing.
Fig. 4 represents a plan of the catch the provision in which of the rubber ring or
band obviates noise due to vibration.
At Fig. 5 is shown in side view a modified form of my improved catch.
Fig. 6
is a plan thereof. In this arrangement the bar c is approximately straight and the
whole of the rubber-clad roller e including the ring normally lies below the level
of the top of the vehicle sides a. In closing the door. the bar c is raised
mechanically as in the arrangement first above described, and the door or tail-
board b passes under the rubber-encircled roller e.
"
It will be seen that in the modification shown at Figs. 5 and 6 of the drawings,
the door when closed cannot be opened by being pulled back only. It is necessary
for release of the door to raise the spring bar e by hand, and, for this purpose, the
said bar is furnished at the outer end with a handle or plate g for application of the
upward pressure necessary to raise the roller.
Having now, particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. A catch for the doors of dog-carts and other vehicles, consisting of a roller
such as d encircled by a band or ring of india-rubber such as f, or its equivalent,
the said roller being free to rotate in bearings situated towards the outer end of a
spring bar such as c so attached to the sides of the vehicle (or to other suitable part
thereof) as to rise at its outer end when the tail-board or door is sufficiently
forcibly brought into contact with the rubber-encircled roller and thus to allow
the door or tail-board top to pass below it in either opening or closing, substantially
as hereinbefore described and shown in the accompanying drawings.
2. The modified catch under which the whole of the rubber-clad roller d
including the band or ring flies below the level of the top of the vehicle sides or
other like or analogous place of attachment of the spring bar o carrying the said
roller, and in which the said bar is fitted with a handle or plate 9 for application of
manual pressure to raise the roller for release of the door or tail-board, substantially
as herein before described and shown in the accompanying drawings.
Dated this 3rd day of July 1894.
