We, SAMUEL WILKES, & JONAH WILKES, Excelsior Works, Bloxwich, in the
County of Stafford, Lock Manufacturers, do hereby declare the nature of this
invention to be as follows:-
Our invention cheifly relates to the sliding seats of dog carts & other traps, &
also in part to the fixed seats of other vehicles. As applying to dog carts and other
traps in the first place we construct a rail for screwing to the sides of the body of
the vehicle for the seat to rest & slide upon. The top part upon which the seat
rests is made from a hollow tee section which may be drawn from any suitable
sheet metal, & this we rivet to a piece of shape angle iron of suitable length, by
inserting one of the sides of it into the bottom part of the tee section holes are
then drilled through the parts for rivetting them together.
We then make guides for fastening to the underside of the seat at the ends, of
suitable section to grasp the tee part of the rail in such a manner to prevent it
ising upwards from the body of the vehicle & allow it to slide upon the afore-
said rail, & these guides we may either cast or preferably make them from sheet
metal drawn or stamped to the shape required.
Also further to counteract some of the vibration felt from the ordinary way of
attaching the seat to the body of the vehicle, we may interpose an india rubber
cushion which may be solid or partly solid, or we may use an india rubber air tube
for inflating, between the guides that grasp the aforesaid rails & the seat of the
vehicle, secured to the guides & the seat by dovetailed lips formed on them and
these fit into corresponding dovetail channels formed on the top side of the guides
& a dovetailed section of metal with flanges on it for screwing to the underside of
the seat.
In the case of the seats of vehicles other than dog carts to interpose india rubber
cushions, whether air or otherwise, between the seat rail & the seat, we form dove-
tail lips on them in the aforesaid manner, for attaching them to dovetail sections
of iron or other metal with flanges formed on them for screwing to the seat rail
&to the seats.
To fix the seat in the required position for balancing the vehicle upon the axle
also to securely fasten it in its place, holes are made at suitable distances apart
in the rails attached to the body of the vehicle into which spring bolts are shot
from the ends of a semi-cylindrical case which we fix on the underside of the seat
at or about the centre with flanges formed on it for screwing thereto, and in these
langes on the part that lies underneath the seat we form recesses to support a

page_text: metal plate with bearings fixed on it and these lie inside the casing at suitable
distances from the ends, between these bearings the metal is partly cut away from
the casing to allow a handle to pass through supported at the top & to admit of it
turning in the bearings, between the part so supported the metal is cut away in
the centre and a double square thread is formed opposite each other of rapid pitch
right & left hand. The spring bolts which pass through the ends of the casing
also pass through the part of the handle that turns in the bearing & partly meet
in the centre of the space cut away. On the ends of these bolts nuts are
fastened with threads cut on them to correspond with the threads cut on the parts
of the handle supports & to prevent these nuts from turning a shoulder is formed
on the part that faces the metal plate fixed on the flanges of the casing & this
works in a slot formed in the plate.
To withdraw the bolts from the holes in the rails the bottom end of the handle
is lifted up which causes the screw threads formed on it to act on the nuts to which
the rods are attached & they are drawn simultaneously toward each other, and
released from the holes in the angle bar of the rails, & allow the seat to be adjusted
the pressure from the springs acting on the bolts causes them to again shoot out-
wards into corresponding holes in the bar on the release of the handle.
The spiral springs which operate the bolts are fixed in the ends of the casing
abut against the handle bearings & a split pin which passes through the bolts, on
being withdrawn they are compressed & on the release of the handle they again
force them outwards.

Improvements in Seats for Vehicles, and Fittings connected
therewith.
We, SAMUEL WILKES, & JONAH WILKES, of Excelsior Works, The Green,
Bloxwich, in the County of Stafford, Lock Manufacturers, 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:―
As applying to dog carts & other traps, in the first place we construct a rail, A
shown in section in Fig. 2, for screwing to the sides of the body of the vehicle for
the seat to rest & slide upon. The top part B upon which the seat rests, is made
from a hollow tee section which may be drawn from any suitable sheet metal &
this we rivet to a piece of L shape angle iron, C of suitable length, by inserting
one of the sides of it into the bottom part of the tee section. Holes are then
drilled through the parts for rivetting them together. We then make guides, D,
likewise shewn in section Fig. 2 for fastening to the underside of the seat at the
ends, of suitable section to grasp the tee part of the rail in such a manner to
prevent it rising upwards from the body of the vehicle & allow it to slide upon
the rails, & these guides we may either cast or preferably make them from sheet
metal drawn or stamped to the shape required.
Also further to counteract some of the vibration felt from the ordinary way of
attaching the seat to the body of the vehicle, we may interpose an india rubber
cushion which may be solid or partly solid, E, Fig. 3 or we may use an india, rubber
air tube for inflating between the guides, D, shown in section, Fig. 3, that grasp

page_text: the aforesaid rails & the seat of the vehicle, secured to the guides, D, & the seat
by dovetailed lips, F, formed on them, & these fit into corresponding dovetail
channels formed on the topside of the guides & a dovetailed section of metal, G,
with flanges on it for screwing to the underside of the seat.
In the case of the seats of vehicles other than dog carts to interpose india rubber
cushions whether air or otherwise between the seat rail & the seat we form dove-
tail lips on them in the aforesaid manner for attaching them to dovetailed sections
of channel iron or other metal, with flanges formed on them for screwing to the
seat rail & to the seats.
To fix the seat in the required position for balancing the vehicle upon the axle
& also to securely fasten it in its place holes are made at suitable distances apart in
the rails, A, Fig. 2, attached to the body of the vehicle, into which spring bolts H, are
shot from the ends of a semi-cylindrical case, 1 which we fix on the underside of
the seat at or about the centre with flanges formed on it for screwing thereto, and
in these flanges on the part that lies underneath the seat we form recesses, J, to
support a metal plate, K, Fig. 1 with bearings, L, Fig. 2, fixed on it and these lie
inside the casing at suitable distances from the ends, between these bearings the
metal is partly cut away from the casing to allow a handle, M, to pass through
supported at the top, & to admit of it turning in the bearings, between the par
so supported the metal is cut away in the centre and a double square screw thread
is formed opposite each other of rapid pitch right & left handed. The spring
bolts, H, which pass through the ends of the casing also pass through the parts
of the handle that turns in the bearing & partly meet in the centre of the space
cut away, on the ends of these bolts nuts N Fig. 2, are fastened with threads cut
on them to correspond with the threads cut on the parts of the handle supports, &
to prevent these nuts N from turning a shoulder & stud is formed on the part that
faces the metal plate fixed on the flanges of the casing & this works in a slot P,
formed in the plate.
To withdraw the bolts from the holes in the rails the bottom end of the handle. M,
is lifted up which causes the screw threads formed on it to act on the nuts to which
the rods are attached & they are drawn simultaneously toward each other and
released from the holes in the angle bag of the rails, & allow the seat to be
adjusted, the pressure from the springs acting on the bolts causes them to again
shoot outwards into the corresponding holes in the bar on the release of the
handle, the spiral springs which operate the bolts are fixed in the ends of the
casing abut against the handle bearings L & a split pin o, which passes through
the bolts, on the bolts being withdrawn they are compressed & on the release of
the handle they are again forced outwards.
On referring to the drawings..
Fig. I, is a plan of the locking arrangement & side rails with guides fixed in
position with seat removed.
Fig. II, is a front elevation of same likewise shown in position with bolts shown
in the locked position.
Fig. III is a section of a guide or runner with india rubber cushion fixed between
them.
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
:
I. The manner of constructing side rails and guides for the sliding seats of
0 vehicles, as described & illustrated by the accompanying drawings.
II. The interposing of india rubber cushions, air or otherwise between the guides
& the seat of the vehicle in such a manner or any other suitable way, as shown.
in section Fig. 3 of the drawing.
III. The construction of the locking mechanism for operating & withdrawing
5 the spring bolts from the holes made in the side rails for their reception for lock-
ing the seat in the required position by right & left hand helices formed on the

page_text: corresponding various parts described and illustrated by the accompanying
drawings.
IV. The combination of the various parts for the aforesaid purposes substan-
tially as described.
