PROVISIONAL SPECIFICATION.
Improved Means for Adjusting and Looking the Seats of Dog Carts,
Traps, and like Vehicles.
I, HENRY ALDERTON, of 11, Sidbury, Worcester, Worcestershire, Coach Body
Maker, do hereby declare the nature of this invention to be as follows:-
This invention cousists of the hereindescribed improved means for adjusting and
locking the seats of dog carts traps and like vehicles.
In carrying out my invention I fix to the underside of the seat and preferably at
about the centre of the same a small metal box containing a slide which extends
from the front towards the back of the seat and is suitably guided by the box so as
to be free to be moved to and fro. The front end of this slide is acted upon by a
lever handle jointed to a front projecting part of the box and made with a heel
and so arranged that when the handle is raised the centre slide will be pushed
back. A suitable spring pushes the said slide forward again and maintains the
lever handle in its turned down position. Connected to the said slide by jointed
side links there are two sliding bolts one bolt on one side of the slide and the other
bolt on the other side of the same these bolts extending to the sides of the seat
where they pass through blocks or bearings which are screwed or otherwise fixed
to the underside of the seat and the ends of the bolts engage in holes in metal slide
bars preferably of angle section which I provide and fix on the seat rails or top of
the sides of the trap or other vehicle.
When the lever handle is raised as aforesaid the slide is by the lever handle
pushed backwardly and the two bolts are by their connections to the slide drawn
inwardly so that the ends of the bolts are free of the holes in the slide bars. The
seat can then be moved to and fro along the slide bars and adjusted to the position
required and then when the lever handle is allowed to resume its original turned
down position the spring on the slide causes the slide to move forward and the
sliding bolts to move outwardly again and engage with holes in the slide bars and
thus lock the seat in the position required. The slide bars are by preference made
of angle section metal as above described and screwed on to the top and inner faces
of the seat rails the holes with which the sliding bolts engage being made in the
vertical inner faces of the slide bars. The underside of the seat which bears upon
the top of the slide bars is by preference made with metal runner pieces or pads
screwed to it so as to run freely upon the slide bars. In order to prevent the scat
from rising each of the said blocks or bearings which are screwed on to the
underside of the seat and through which the sliding bolts pass as aloresaid is made
with a plate having an upwardly projecting channel edge which engages with the
bottom edges of the slide bars and thus prevents the seat from rising and also
assists in preventing the sides of the vehicle from springing apart.
Instead of the sliding bolts being withdrawn by the slide to which they are
jointed being pushed backwardly as stated above the sliding bolts may be arranged
to be withdrawn by the slide being pulled forward by the raising of the handle as
above described.

I, HENRY ALDERTON, of 11, Sidbury, Worcester, Worcestershire, Coach Body
Muker, 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 consists of the herein-described improved means for adjusting and
locking the seats of dog carts traps and like vehicles.
I will describe my invention by referring to the accompanying drawings on
which
Fig. 1 is a front elevation of a dog cart seat with my invention applied; Fig. 2
is an inverted plan of the same; Fig. 3 is a longitudinal sectional elevation of the
same taken on line a a of Fig. 1; Fig. 4 is a longitudinal, sectional elevation of
the same taken on line Y Y of Fig. 1;
Fig. 5 is a sectional plan of a modification of my invention and Fig. 6 is a
sectional elevation of the same.
The same letters of reference indicate the same or corresponding parts in all
the figs.
Referring firstly more particularly to Figs. 1, 2, 3 and 4, in carrying out my
invention I fix to the underside of the seat A and preferably at about the centre
of the same a small metal box B containing a slide C which extends from the
front a¹ towards the back a² of the seat and is guided by the ends 61 62 of the box B
so as to be free to be moved to and fro. The front end c¹ of this slide C is acted
upon by a lever handle D jointed to a front projecting part 63 of the box and made
with a heel d and so arranged that when the handle is raised the heel d' will push
back the centre slide C. The coiled wire spring fon the slide C pushes the slide C
forward again and maintains the lever haudle D in its turned down position shewn
in Figs. 1, 2 and 3. Connected to the slide C by the two jointed side links G¹ G²
there are two sliding bolts H' H2 one bolt namely H' being on one side of the
slide C and the other bolt H2 on the other side of the same, these bolts extending
to the sides of the seat A where they pass through the blocks or bearings I' I'
which are screwed or otherwise fixed to the underside of the seat and the outer
ends A' of the bolts H' H engage in holes j in metal slide bars J1 J2 preferably of
angle section which I provide and fix on the seat rails K¹ K' or on the top of the
sides of the trap or other vehicle.
When the lever handle D is raised by being turned about in its fulcrum e is by
the heel of the lever handle D pushed backwardly and the two bolts H¹ H² are
by the links G' G' connecting them to the slide C-drawn inwardly so that the
ends of the bolts HH2 are free of the holes ; in the slide bars JJ. The
seat A can then be moved to and fro along the slide bars J J and adjusted to
the position required and then when the lever handle D is allowed to resume its
original turned down position shewn by Figs. 1, 2 and 3 the spring f on the slide C
causes the slide C to move forward and the sliding bolts H' H' to move outwardly
again and engage with two of the boles ; in the slide bars J J2 and thus lock the
seat A in the position required. The slide.bars J1 J2 are by preference made of
angle section metal as above described and screwed on to the top of the seat rails
as shewn the holes j with which the sliding bolts H'H' engage being made in the
vertical inner faces of the slide bars. The underside of the seat A which bears
upon the top of the slide bars J'Jis by preference made with metal runner pieces
or pads Lscrewed to it so as to run freely upon the slide bars. In order to
prevent the seat A from rising each of the blocks or bearings 1'1' (which are by
:

page_text: preference formed in a piece to the runner pieces or pads L' L²) is made with an
upwardly projecting channel edge ¹ which engages (see Fig. 1) with the bottom
edges of the slide bars J1 J2, and the runner pieces or pads have two other similar
blocks also made with upwardly projecting channel edges engaging with the
bottom edges of the slide bars J¹ J thus preventing the seat A from rising and
also assisting in preventing the sides M' M³ of the vehicle from springing apart.
Instead of the sliding bolts H'H' being withdrawn by the slide C to which they
are jointed being pushed backwardly as above described with reference to Figs. 1
to 4 the sliding bolts H¹ H2 may as shewn in Figs. 5 and 6 be arranged to be
withdrawn by the slide C being pulled forward by the raising of the handle D. In
this case the upper part of the handle D is jointed at n to the front part of the
box B and is jointed at o to the slide C at some little distance below the fulcrum
pin n.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I hereby declare that
what I claim is :-
1. The combination with the sliding seat of a dog cart trap or like vehicle of a
metal box or casing fixed to the underside of the seat, a spring slide carried by said
box or casing and extending from the front towards the back of the seat and
arranged for end wise movement, the two locking bolts H'H' connected by side
links G G to the said spring slide and extending to the sides of the seat and
adapted to connect with holes or notches in the metal slide bars supporting the
seat, and the handle D at the front of the seat adapted to turn up or down and so
arranged that when the handle is turned up the spring slide will be moved endwise
and the locking bolts withdrawn from the slide bars, and when the handle is turned
down the said locking bolts will by the spring slide be forced outwardly ready to
engage with the slide bars and lock the seat, all substantially as hereinbefore set
forth.
2. The combination with the seat locking mechanism of the kind denoted under
Claim One, of the slide bars J' J' fixed to the seat rails or to the top of the sides
of the trap or like vehicle and the pads or runners L' L' fixed to the underside of
the seat and bearing on and engaging with the slide bars and also guiding the said
locking bolts H H all substantially as hereinbefore described and illustrated by
the accompanying drawings.
3. The combination of parts forming the improved means for adjusting and
locking the seats of dog carts traps and like vehicles constructed and arranged
substantially as herein before described and illustrated by Figs. 1, 2, 3 and 4 of the
accompanying drawings.
4. The combination of parts forming the improved means for adjusting and
locking the seats of dog carts traps and like vehicles constructed and arranged
substantially as hereinbefore described and illustrated by Figs. 5 and 6 of the
drawings.
