PROVISIONAL SPECIFICATION.
Improved Means for Adjusting and Locking the Seats of Traps,
Dog Carts, and like Vehicles.
We, CHARLES HENRY MARSHALL, FRANK SANDERS, NAYLOR SMYTHE,
and JOSEPH SMITH RICHARDS, trading together as Joseph Richards and
Company, of Spring Hill Coach Iron Works, Birmingham, Warwickshire,
Manufacturers, do hereby declare the nature of this invention to be as follows:-
This invention has reference to means for adjusting and locking the seats of
traps, dog carts, and like vehicles and consists in arranging the parts as herein
described, whereby the required adjustment and locking of the sent is rendered
very easy and the seat is effectually prevented from rattling.
In carrying out this invention we provide a two armed lever underneath the
seat which can be turned about a fulcrum pin fixed to the said seat one arm of this
lever projecting in front of the seat and shaped as a knob or handle for moving
the said lever to and fro. The two arms of this lever are respectively jointed to
two bolts which work in guides fixed to the underside of the seat and which extend
to the ends of the scat and engage in a series of holes or notches in the metal slides
which are fixed to the tops of the seat rails. These slides are by preference made
of a section somewhat similar to a flanged rail of a railway and the seat is made
with metal runners underneath which are shaped to engage under the heads of the
slides and prevent the seat lifting. Each of the said runners is or may be also
provided with one or more india rubber or other rollers adapted to roll along the
slides and thus cause the seat to move easily to and fro. The india rubber rollers
also prevent any rattling of the seat on the slides. A spiral or other spring on one
of the bolts, or otherwise arranged, acts upon the bolts and the lever and keeps the
bolts projecting outwardly engaging with the holes or notches in the slides.
To adjust the seat, the handle end of the said lever has to be pressed sideways
so as to withdraw the outer ends of the bolts from the holes or notches in the
slides. The seat will now be free to be moved to or fro and adjusted as required,
and when its required position has been obtained the said spring will cause the two
bolts to spring outwardly and engage with the corresponding holes or notches in
the slides and thus lock the seat in its required position.
Fixed to the front of the seat there is a slotted guide in which the lever works.

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention has reference to means for adjusting and locking the seats of
traps, dog carts and like vehicles and consists in arranging the parts as herein
described, whereby the required adjustment and locking of the seat is rendered
very easy and the seat is effectually prevented from rattling.
We will describe this invention by referring to the accompanying drawings in
which Fig. 1 is an inverted plan of the seat and sides of a dog cart or like vehicle
with our invention applied thereto; in this view the seat is shewn locked to the
slides; Fig. 2 is also an inverted plan of the same shewing the seat unlocked and
free to be moved to or fro along the slides; Fig. 3 is a sectional side elevation and
Fig. 4 is a front elevation of the same; Fig. 5 is a sectional front elevation;
Fig. 6 is a plan and Fig. 7 is a cross section of a part of the locking mechanism on
an enlarged scale; Fig. 8 is a sectional front elevation; Fig. 9 is a plan on an
enlarged scale of another part of the locking mechanism at the other end of
the seat.
The same letters of reference indicate the same parts in all the figures.
A is the sliding seat and B B are the two sides of the trap, dog cart or like
vehicle, are the two seat rails fixed to the sides B' B2 and supporting the
seat A.
The
In carrying out this invention we provide a two armed lever C underneath the
seat A which can be turned about a fulcrum pin D fixed to a base plate d' which
is fixed to the seat A. One arm of the lever C projects in front of the seat and is
shaped as a knob or handle for moving the lever C to and fro. The two
arms of this lever C are respectively jointed to two bolts E¹ E' which work in
guides F and G fixed to the underside of the seat A. These bolts E' E' extend
to the ends of the seat A and engage in a series of holes or notches h¹ in the metal
slides H H which are fixed to the tops of the seat rails 66. These slides H'H'
are (as shewn in Figs. 4, 6 and 8) by preference made of a section somewhat
similar to a railway rail, that is to say, each slide has a head and a vertical
web in which latter are the holes or notches ₁ for the cross bolts E' E'.
slides H H are fixed to the seat rails 61 b by the angle brackets or flanges h* or
by other suitable means. The seat A is made with four metal runners underneath
marked respectively F, G, I and J which are shaped as shewn to engage under-
the heads of the slides and prevent the seat A from lifting. Each of the
runners F, G. I and J is or may be also provided with one or more india rubber or
other rollers K turning on pins k¹ and adapted to roll along the tops of the
slides H H and thus cause the seat A to move easily to and fro and also prevent
any rattling of the seat A on the slides H H. The spiral spring L on the bolt E³
between the crosspin e of the bolt and the fixed boss gl of the guide G, or other-
wise arranged, acts upon the bolts E¹ E2 and the lever C and keeps the bolts E' E'
projecting outwardly engaging with the holes or notches in the slides H¹ H².
To adjust the seat A the handle end c of the lever C has to be pressed sideways
as shewn in Fig. 2 so as to withdraw the outer ends ee of the bolts E' E' from
the holes or notches in the slides H₁ H2. The scat A will now be free to be
moved to or fro along the slides H1 H2 and adjusted as required, and when its
required position has been obtained the handle is released and the spring L will
cause the two bolts E¹ E2 to spring outwardly as shewn in Figs. 1 and 4 and engage
with the corresponding holes or notches in the slides H H and thus lock the
Beat A in its required position.
Fixed to the front of the seat A there is a slotted guide M in which the lever C
works.
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 combination with the sliding seat of a trap dog cart or like vehicle, of a

page_text: two armed lever handle jointed to the underside of the same so as to move to and
fro horizontally, the two locking bolts E¹ E' jointed respectively to said lever
arms and extending to the sides of the seat to engage in holes or notches in the
seat slides, and the runners such as F G I and J fixed to the underside of the seat
and engaging under the heads of the seat slides, two of said runners also forming
guides for the said bolts, the whole arranged substantially as herein before described
and illustrated by the accompanying drawings and for the purposes set forth.
2. In an appliance for adjusting and locking the seats of traps dog carts and like
vehicles, the combination with the seat of the headed slides H'H' fixed to the
seat rails, and the runners F, G, I and J fixed to the underside of the seat and
engaging under the seat rails and made with the rollers K to run along the seat
rails, substantially as hereinbefore described and illustrated by the accompanying
drawings.
3. The improved means for adjusting and locking the seats of traps dog carts.
and like vehicles constructed and arranged substantially as herein described and
illustrated by the accompanying drawings.
