I HENRY MILLINGTON HEMMING of Arrow, near Alcester, in the County of
Warwick, Carriage Builder do hereby declare the nature of this invention to be as
follows:-
My invention consists of the construction and combination of parts hereinafter
described for adjusting and fastening the sliding seats of dog-carts, Whitechapel and
other traps and other two-wheeled vehicles and vans having sliding seats whereby
the adjustment of the position of the seat and the fastening of it in its. adjusted
position can be effected with great facility and without the rider leaving his
seat.
I will describe my invention as applied to a dog-cart or trap.
On the underside of the sliding seat and near the front thereof, I arrange two
sliding bolts for bolting or fastening the seat at its opposite ends to the body of the
dog-cart or trap. These sliding bolts work in guides and have motion in opposite
directions so that they are simultaneously shot into or withdrawn from the staples
or recesses at the sides of the body of the dog-cart or trap. The said sliding bolts
are operated in the following manner. At the middle of the underside of the seat
a vertical lever is situated the axes of the said lever turning in a bracket fixed to
the underside of the seat and also turning in the front bar of the seat. The axis of
the lever projects from the front bar of the scat and can be turned by a.handle fixed
to or fitted on the said projecting end. The inner end of one of the sliding bolts is
jointed to the upper arm of the lever and the inner end of the other bolt is jointed
to the lower arm of the said lever. By means of a strong plate spring bearing on
the heel of the upper bolt the two bolts when released are simultaneously shot into
their staples or recesses. In order to withdraw the bolts and unfasten the sliding
seat, it is only necessary to turn the axis of the lever through a small angle by means
of its handle when the arms of the lever moving in opposite directions simultaneously
withdraw the two bolts.
The seat is supported at its opposite ends on ledges fixed to the sides of the trap
or dog-cart. I prefer to form these ledges by strips of angle iron which are fixed
to the sides of the vehicle by their vertical webs, the horizontal webs constituting
the supporting ledges of the sliding seat. In the edges of the said ledges equi-
distant rectangular recesses are made for the outer ends of the two bolts to snap
into or engage with, the heads of the bolts having the required figure given to them
for taking into the said recesses.
In adjusting the position of the sliding seat it is only necessary for the rider to
turn the handle at the middle of the front bar of the seat. The two bolts are
thereby simultaneously withdrawn from the recesses in the ledges described and the
seat unfastened. By now sliding the seat backwards or forwards on its ledges until
its position has been adjusted and then releasing the bolts, the latter snap into the
recesses or staples in the ledges opposite to which they have been brought and the
seat is thereby fastened in its adjusted position. The rider can in this way adjust
the position of and fasten the seat without rising from the said seat.

Improvements in the Sliding Seats of Dog-carts, Whitechapel and
other Traps, and other Vehicles.
1, HENRY MILLINGTON HEMMING of Arrow near Alcester, in the County of
Warwick, Carriage Builder, do hereby declare the nature of my invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention consists of the construction and combination of parts hereinafter
described for adjusting and fastening the sliding seats of dog-carts, Whitechapel and
other traps and other two-wheeled vehicles and vans having sliding seats, whereby
the adjustment of the position of the seat and the fastening of it in its adjusted
position can be effected with great facility and without the rider leaving his
séat..
I will describe my invention as applied to a dog-cart or trap.
On the underside of the sliding seat and near the front thereof, I arrange two
sliding bolts for bolting or fastening the seat at its opposite ends to the body of the
dog-cart or trap. These sliding bolts work in guides and have motion in opposite
directions so that they are simultaneously shot into or withdrawn from the staples
or recesses at the sides of the body of the dog-cart or trap. The said sliding bolts
ařé operated in the following, manner.
At the middle of the underside of the seat a vertical lever is situated the axis of
the said lever turning in a bracket fixed to the underside of the seat and also
turning in the front bar of the seat. The axis of the lever projects from the front
bar of the seat and can be turned by a handle fixed to or fitted on the said pro-
jecting end. The inner end of one of the sliding bolts is jointed to the upper arm
of the lever and the inner end of the other bolt is jointed to the lower arm of the
said lever By means of a strong plate spring bearing on the heel of the upper bolt
the two bolts when released are simultaneously shot into their staples or recesses.
In order to withdraw the bolts and unfasten the sliding seat it is only necessary to
turn the axis of the lever through a small angle by means of its handle when the
arms of the lever moving in opposite directions simultaneously withdraw the two
.bolts.
The seat is supported at its opposite ends on ledges fixed to the sides of the
trap or dog-cart. I prefer to form these ledges by strips of angle iron which are
fixed to the sides of the vehicle by their vertical webs, the horizontal webs con-
stituting, the supporting ledges of the sliding seat. In the edges of the said ledges,
equi-distant rectangular recesses are made for the outer ends of the two bolts to
snap info or engage with, the heads of the bolts having the required figure given
to them for taking into the said recesses.
Figure 1 of the accompanying drawing represents in isometrical perspective the
body of a dog-cart or trap with which a sliding seat and appliances connected
therewith constructed according to my invention are combined';
Figure 2 represents in section and Figure 3 in plan of underside (partly in
section): the said seat and appliances drawn to a larger scale..
Figure 4 represents the parts for actuating the sliding bolts drawn to a larger
scale than Figures 2 and 3 and
Figure 5 represents in- section and Figure 6 in plan of underside one of the end's
of the seat and its connection witli the body of the dog-cart or trap drawn to the
same scale as Figure 4.
The same letters of reference indicate the same parts' in the several figures of
the drawing?
a is the sliding seat of the trap or dog-cart and b, bare the sides of the trap or
cart; c, d are the sliding bolts, working in guides e, e on the underside of the
seat a, for fastening or bolting the seat at its ends to the sides of the dog-cart or
trap. These bolts move in opposite directions and are shot simultaneously into or

page_text: withdrawn from the staples or recesses at the sides of the body in the following
manner; ff is a vertical lever on the underside of the seat the arms of the lever
being connected by a central boss carrying the axis g.
The axis g of the lever turns in the bracket A on the seat a and also passes
through and turns in the front bar a² on the seat (see Figure 3). On the
projecting end of the axis g of the vertical leverf, is a handle for turning
the said axis and operating the fastening bolts c, d.
The inner end of the bolt c is jointed to the upper arm of the lever and the
inner end of the other bolt is jointed to the lower arm of the lever as best
seen in Figure 4; A is a strong plate spring bearing on the heel of the bolt c for
simultaneously shooting both bolts when they are released. By turning the
handle into the position indicated in dotted lines at in Figure 4, the arins, f
of the lever, moving in opposite directions, simultaneously withdraw the two
bolts c,
d and unfasten the sliding seat a; 1, 1 are supporting ledges for the opposite
ends of the seat to slide upon, fixed to the opposite sides bb of the trap or dog-
cart. The said ledges, are made of strips of angle iron, the ends of the seat
which bear and rub upon the horizontal webs of the angle iron being protected by the
angle strips m, m. Fixed along each of the ends of the seat is a lipped strip n
the lip of which engages with the top of the vertical part of the supporting angle
strip or ledge. These lipped strips n, n prevent lateral motion in the seat a.
the edges of the ledges 1, 1, equi-distant recesses p, p are made for the outer ends
or heads of the two bolts c, d to snap into or engage with.
In
Under the outer ends of the two bolts are guide plates q, q which when the bolts
are shot engage under the horizontal webs of the ledges l, l'and prevent the rising
of the seat.
In adjusting the position of the sliding seat a it is only necessary for the rider
to turn the handle at the middle of the front bar a² of the seat into the position
indicated at in Figure 4. The two bolts c, d are thereby simultaneously with-
drawn from the recesses p p in the ledges 1, and the seat a unfastened.
By now sliding the seat a backwards or forwards on its ledges 1, 1 until its
position has been adjusted and then releasing the bolts, the latter snap by the
action of the spring into the recesses or staples p, p in the ledges 1, opposite
to which recesses they have been brought, and the seat is thereby fastened in its
adjusted position. The rider can in this way adjust the position of and fasten the
seat without rising from the said seat.
I apply my improvements to the sliding seats of two wheel vehicles generally
and to vans substantially in the manner hereinbefore described and illustrated with
respect to the sliding seat of a dog cart or trap.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention:-
-
The combination or arrangement of parts substantially as hereinbefore described
and illustrated in the accompanying drawing for adjusting and fastening the sliding
seats of dog-carts, Whitechapel and other traps and other vehicles: that is to
say, arranging under the sliding seat, two fastening bolts so connected to the arms
of a vertical lever, operated by a handle and pressed upon by a spring, that the
said bolts have motion in opposite directions, the turning of the handle simul-
taneously withdrawing the bolts from staples or recesses in ledges at the sides of
the body of the vehicle and unfastening the seat and the releasing of the said
handle causing the two bolts to be simultaneously shot into the said staples or
recesses for fastening the seat, the several parts being arranged and acting
substantially as described and illustrated.
