Improvements in the Fittings of Adjustable Seats of Traps and
other Vehicles.
I, GEORGE WEARING, of Carter's Green Foundry, West Bromwich,
Staffordshire, Ironfounder, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to metal fittings for the adjustable seats of traps
dog-carts and those other vehicles which have adjustable cross seats which require
to be adjusted and fixed either nearer to or farther from the front of the vehicle and
the said fittings when made according to my invention have the further object of
preventing the sides of the vehicle springing farther apart by the weight on
the seat.
I also
According to one arrangement of carrying out my invention I provide two metal
bearing plates or bars which are respectively fixed to the ledges on the sides of the
trap or other vehicle on which ledges the ends of the seat usually rest.
provide two metal runners which are metal plates or bars of special form fixed
respectively to the ends of the seat at the underside thereof and which rest upon
the said two bearing plates. The said runners and the bearing plates are formed
so as to engage together and prevent the sides of the trap or other vehicle springing
farther apart. That is to say there is a longitudinal rib on the top side of each of
the bearing bars which takes into a corresponding groove formed along the under
side of each of the runners; or there is a longitudinal rib formed on each of the
runners to take into a corresponding groove formed along each of the bearing bars.
When the seat is moved nearer to or farther from the front of the trap or other
vehicle the runners engaging with the bearing plates keep the seat square.
In order to removeably fix the seat in any desired position I provide at the front
end of each of the runners and hinged or otherwise fixed thereto a metal link and
in the bearing plate I form inclined (and by preference undercut) notches so
arranged that the said links will take into one or other of these notches and prevent
the seat moving farther back. The said notches are inclined downwardly from the
front towards the back so that the seat is always free to be moved forwards
To move the seat
the links moving up the inclines and into the notches.
backwardly the links have first to be raised. Only one link may be used if desired
and when the other link is not required it may be turned up out of the way.
Instead of using the said links to fix the seat, catches or other means may be
employed as for instance projections on the underside of the runners to take into
the notches or holes in the bearing bars or plates.

COMPLETE SPECIFICATION.
Improvements in the Fittings of Adjustable Seats of Traps and
other Vehicles.
1, GEORGE WEARING, of Carter's Green Foundry, West Bromwich,
Staffordshire, Ironfounder, 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 metal fittings for the adjustable seats of traps

page_text: dog-carts and those other vehicles which have adjustable cross seats which require
to be adjusted and fixed either nearer to or farther from the front of the vehicle
and the said fittings when made according to my invention have the further object
of preventing the sides of the vehicle springing farther apart by the weight on
the seat.
According to one arrangement of carrying out my invention I provide two metal
bearing plates or bars which are respectively fixed to the ledges on the sides of the
trap or other vehicle on which ledges the ends of the seat usually meet. I also
provide two metal runners which are metal plates or bars of special form fixed
respectively to the ends of the seat at the underside thereof and which rest upon
the said two bearing plates. The said runners and the bearing plates are formed
so as to engage together and prevent the sides of the trap or other vehicle springing
farther apart. That is to say there is a longitudinal rib on the top side of each of
the bearing bars which takes into a corresponding groove formed along the
underside of each of the runners or there is a longitudinal rib formed on each of the
runners to take into a corresponding groove formed along each of the bearing bars.
When the seat is moved nearer to or farther from the front of the trap or other
vehicle the runners engaging with the bearing plates keep the seat square.
In order to removably fix the seat in any desired position I provide at the front
end of each of the runners and hinged or otherwise fixed thereto a metal link and
in the bearing plate I form inclined (and by preference undercut) notches so
arranged that the said links will take into one or other of these notches and
prevent the seat moving farther back. The said notches are inclined downwardly
from the front towards the back so that the seat is always free to be moved forwards
the links moving up the inclines and into the notches. To move the seat
backwardly the links have first to be raised. Only one link may be used if desired
and when the other link is not required it may be turned up out of the way.
Instead of using the said links to fix the seat, catches or other means may be
employed as for instance projections on the underside of the runners to take into
the notches or holes in the bearing bars or plates.
On the accompanying drawings
Fig. 1 is a sectional side elevation of a dogcart seat and part of the body with
one form of my invention applied ;
Fig. 2 is a sectional plan of the same and
Fig. 3 is a front sectional elevation of the same;
Fig. 4 shews one of the runners of the same separately in side and end elevation
and in plan and
Fig. 5 shews one of the bearing plates or bars of the same separately in side and
end elevation and in plan.
The same letters of reference indicate the same or corresponding parts in all the
figures of my drawings.
A. A are the two metal bearing plates or bars which I fix as by screws d to the
sides B of the trap or other vehicle and C C are the two metal runners which I fix
by screws e to the respective ends of the seat D at the underside thereof as shewn
these runners resting upon the two bearing bars A A. There is a longitudinal rib c¹
formed on the underside of each of the runners C C which takes into a
corresponding groove a' formed along each of the bearing bars or plates A A.
It will be seen that the bearing plates or bars A A are in this example of my
invention made of an open channel section and with a rib on each runner which
takes against the inside rib a² of the bearing plate or bar and thus prevents the
sides of the trap or other vehicle from springing farther apart. The runners C C
bear upon the top of the inside ribs a' of the bearing bars and in order to prevent
the seat D rising there is a downwardly projecting part formed on each of the
runners C (as shewn more clearly in Figs. 3 and 4) which at c is continued
underneath the bottom of the bearing plates A A. When the seat D is moved
nearer to or farther from the front of the trap or other vehicle the runners CC
engaging with the bearing plates A. A as above described keep the seat D square

page_text: with the sides of the trap. In this example of my invention each of the runners C C
has jointed to its front end a hook catch F which projects downwardly at fl so as
to take into any one of a series of holes a' which I form in the bottom web a' of
each of the bearing plates or bars A so as to keep the seat D in any desired
position. Each of the hooks F has a front projecting part f' by which the hooks
can be raised when it is desired to adjust the position of the seat.
In the example of my invention above described and illustrated by Figs. 1 to 5
both inclusive the bearing plates or bars A. are as above stated made of open trough
section and fixed directly to the sides of the trap or other vehicle and in this case
the usual rail for carrying the seat D is unnecessary but when this rail is used the
bearing plates or bars A may be fixed upon these rails as shewn in Figs. 6, 7 and 8
where the said rails are marked g and the bearing plates or bars A are fixed
directly to them by screws d passing through the bottom flanges at of the bearing
plates or bars A. In this case as the side flange a shewn in Figs. 1, 2, 3 and 5 is
not required the bearing plates or bars A are made of the angle section shewn by
Fig. 9 or by Fig. 9*. The downwardly projecting parts of the runners can
either be arranged to take under a projecting side rib such as a" which is formed
near the bottom of the upwardly projecting flange a of the bearing bars A as shewn
in Figs. 8 and 9 or instead as shewn in Fig. 9 the bearing bars A may be of
ordinary section and made to project slightly beyond the seat rail g so as to
form a ledge for the projecting parts cc of the runners to take under as shewn
in Fig. 9*.
Figs. 10, 11, 12, 13 and 14 illustrate a modification of my invention in which
the runners C are hinged at their front ends e to and slide along the bearing bars
or plates A and in order to maintain the seat D in any desired position each of the
runners C has a projection c formed on its underside which is adapted to take into
any one of a series of corresponding holes a³ in the bearing plates or bars A the
back end of each of the runners C is made to engage with slots a' formed in the
bearing bars or plates A by the parts c being made to project at each side as side
pins (see Fig. 13) which engage underneath the upper portions as of the bar A
between these portions as and the seat rails as shewn in Fig. 10 this bearing bar or
runner being inade with strips a' underneath so as to raise the bar A somewhat
slightly above the top of the seat rails y and allow of room for the ends ct of the
runners C to move to and fro. As the bearing bars A A are slotted at a they are
made with side flanges a through which the fixing screws d pass into the side of
the seat rail g for fixing the bearing plates or bars A thereto.
Fig. 15 shews a modified form of the runner and bearing plate or bar herein-
before described with reference to Figs. 10, 11, 12, 13 and 14 the difference being
that whereas the bearing plate or bar in Figs. 10, 11, 12 and 14 is made to fix on to
the seat rail g the bearing plate or bar A in Fig. 15 is made with lugs a¹ for fixing
the bearing plate or bearing bar to the side of the trap or other vehicle without the
seat rail g.
It is to be understood that in the arrangement of my invention shewn by
Figs. 10, 11, 12, 13, 14 and by Fig. 15 the hinged end c' of the seat slide and the
slot a' in the bearing bar A is towards the front of the vehicle so that to adjust the
position of the seat it is only necessary to lift up the back of the seat about
the hinged end c¹ as a centre as shewn in Fig. 10 so as to raise the projections c
out of the holes in the bearing bars and then push the seat back or bring it
forward to the desired position and then lower the seat again for the pro-
jections to engage with the holes as in the bearing bars or slides. When it is
required to entirely remove the seat D from the bearing bars or slides A the seat
has to be brought right up to the front end of the slide a which at a" is widened
so as to permit of the end c' of the slides being lifted out of the slot.
Fig. 16 shews a further modification of my invention in which the upwardly
projecting rib a along which the runner slides is made with the backwardly
inclined notches h with which engages a metal link į jointed to the front of
the runner C and made with a front upwardly projecting part 1 by which the

page_text: link can be lifted from the notches when the seat is being moved and adjusted along
the bearing plates A.
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. In combination with the adjustable cross seat of a trap dogcart or other
vehicle two metal slides fixed respectively to the underside of the ends of the seat
and two bearing bars fixed to the sides of the body of the vehicle or to the seat
rails thereof the said slides and bearing bars being constructed and combined
together in any of the several ways substantially as hereinbefore set forth and shewn
upon the accompanying drawings so as to engage together and prevent the sides of
the vehicle from springing farther apart and also keep the seat square with the sides
of the vehicle and secure the seat in any desired position as set forth.
2. For use with the adjustable cross seat of a trap dog cart or other vehicle, the
metal slides such as C C adapted for fixing to the underside of the ends of the said
cross seat in combination with the bearing bars such as A A adapted for fixing to
the sides of the body of the vehicle or to the seat rails thereof, each of the said
slides C C being made with a longitudinal under rib c¹ engaging with and adapted
to slide along the inner rib a' of the corresponding bearing bar (to prevent the
sides of the vehicle from springing apart and also to keep the seat square with
the sides of the vehicle) and with a downwardly projecting part such as co
engaging under the said bearing bar to prevent the seat from lifting and a hook
link or catch such as F or i jointed to the front end of each bearing bar adapted to
engage with holes or notches therein all substantially as hereinbefore described and
illustrated by Figs. 1, 2, 3, 4 and 5 or by Figs. 6, 7, 8 and 9 and 9* or by Fig. 16
of the accompanying drawings.
3. For use with the adjustable cross seat of a trap dog cart or other vehicle the
metal slides such as C C adapted for fixing to the underside of the ends of the said
cross seat in combination with the bearing bars such as A A adapted for fixing to
the sides of the body of the vehicle or to the seat rails thereof each of the said
slides CC being connected at the front to the bearing bars A A by a sliding hinge
connection such as c' so that the seat can be lifted at the back and moved to or fro
along slots in the bearing bars and the said slides and bearing bars being also
made to engage together substantially as and for the purposes herein before
described and illustrated by Figs. 10, 11, 13 and 14 or by Fig. 15 of the
accompanying drawings.
