I ALFRED DISS of West Bergholt in the County of Essex, Builder and
Contractor do hereby declare the nature of said invention for "IMPROVEMENTS
IN OR APPLICABLE TO ADJUSTABLE SEATS FOR DOGCARTS AND OTHER LIKE TWO
WHEELED VEHICLES to be as follows:—
"
This invention relates to a simple and effective combination and arrangement of
parts whereby the forward or backward adjustment of the seat or seats of Dog
carts and other like two wheeled vehicles for common roads is facilitated whilst
provision is afforded for covering or closing the hind part of the vehicle when used
as a dog pen or game box.
According to my said invention I combine with each end of the adjustable seat
or seats two distinct sets of antifriction rollers by preference mounted in a casting
screwed or otherwise secured to the underside of each end of the seat or seats. The
rollers of the one set have horizontal axes and run along the upper surface of the
ordinary or other seat rails or supports which are secured to the inner sides of the
vehicle whilst the rollers of the other set have vertical axes and run against the
inner edges of the rails or supports and are further provided with flanges which
enter beneath the said rails in order to prevent the seat from tipping or being
lifted or accidentally jerked from off its supporting rails. In combination with the
before mentioned peculiar arrangement of antifriction rollers which greatly facilitate
the traverse of the seat or seats I employ a traversing screw spindle which turns
freely in a bracket or bearing secured to the front seat and works through a nut
attached to a cross bar fixed to the sides of the vehicle and situate in any convenient
position below the seat or seats said traversing screw being provided with an
actuating handle at the front end and with a removeable knob or enlarged head at
the opposite end to prevent it from being accidentally withdrawn from the nut on
the fixed cross bar. The same arrangement may also be applied for moving the
Di 931

page_text: back seat independently if desired. In vehicles provided with front and back seats
I employ one or more self acting spring catches or couplings attached to either of
the seats so that the two seats by the act of bringing them together will be
connected. To the back adjustable seat I hinge a separate flap which forms a lid
or cover to the hinder part of the vehicle forming the Dog pen or box when the
seat is adjusted to its forward position and can be turned back out of the way onto
the seat when adjusted to its backward position for the accomodation of two extra
riders. The before mentioned improvements are equally applicable to existing as
well as to new vehicles.

'I ALFRED DIss of West Bergholt in the County of Essex Builder and
Contractor 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 relates to a simple and effective combination and arrangement
of parts whereby the forward or backward adjustment of the seat or seats of Dog
Carts and other like two wheeled vehicles for common roads is facilitated.
Figure 1 of the drawings annexed is a cross section of the body of a Dog Cart
showing some of my improvements applied thereto.
Figure 2 is a corresponding plan of the same.
Figure 3 is a longitudinal section of a portion of the body corresponding to
Figure 1.
The rest of the figures are details which will be hereinafter fully referred to.
,
a is the body of a dog cart or similar two wheeled vehicle. b and c are the
adjustable front and back seats respectively. With each end of the adjustable
seat or seats I combine two distinct sets of antifriction rollers & and e by preference
mounted in a casting ƒ as shewn in the detail side view, underside plan and end
view at figures-4, 5, and 6, respectively said casting being secured to the underside
of the seat or seats at each end thereof (see Figure 1). The rollers d of the one
set have horizontal axes and act as supporting rollers running along the upper
surface of the ordinary or other seat rails or supports g by preference of angle iron
secured to the inner sides of the vehicle (see figures 1, 2 and 3) and the rollers e
of the other set have vertical axes and act as guiding rollers running against the
inner edges of the said seat rails or supports these last mentioned rollers being
further provided with flanges h which project beneath the rails g in order to
prevent the accidental rising or lifting of the seat or seats therefrom. i (figures 1,
2 and 7) is a traversing screw spindle moving along with the seat and turning
freely in a bracket or bearing k secured to the front edge of the seat to be
adjusted. The travelling screw i works through a fixed nut l attached to a cross
bar m acting as a cross stay by being fixed at the ends to the two opposite sides of
the vehicle and situate in any convenient position below the seat or seats to suit
the position of the said travelling screw spindle as shewn in figures 1, 2 and 7.
An actuating handle n is provided at the front end of the screw spindle and a
removeable enlarged head o or a cross pin at the opposite end to prevent it from
A similar
being accidentally withdrawn from the fixed nut on the cross bar m.
arrangement in duplicate may also be used if desired for moving the back seat
independently of the front one-An adjustable spring hinged stop or catch is
fitted to the bearing bracket k of the actuating screw spindle as shewn on a larger
scale in detail front and side elevations thereof in figures 8 and 9, said stop being
capable of being adjusted across the path of the handle n, in order to prevent the
screw from being rotated by the vibrations of the vehicle. This stop is maintained
in position either across the path of the handle n (as shown by the full lines) or
P

page_text: away therefrom (as shewn in dotted lines) by the spring q. In vehicles provided
with both front and back adjustable seats I attach to the back of the front seat at
or near the middle thereof a self acting locking spring catch r shewn in position
in the plan view figure 2 and in detail vertical section and front elevation on a
larger scale at figures 10 and 11. The bolt of this catch is forced outwards by a
spring in the casing thereof and is bevelled or inclined at the lower or protruding
end so as to enter freely and engage with a corresponding socket plate & attached
to the edge of the back seat for the purpose of enabling the two seats to be
instantaneously connected or coupled by the act of bringing them together. When
the seats are to be separated they can be instantly released by withdrawing the
spring bolt clear of the socket by the handle t provided for that purpose on the
top of the bolt thus allowing the seats to be separated. The before mentioned
improvements are equally applicable to the adjustable seats of existing as well as
of new vehicles of the kind referred to.
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. The combination with the adjustable seats of Dog Carts and other like two
wheeled vehicles of horizontal supporting rollers in conjunction with vertical
guiding rollers having flanges projecting underneath the supporting rails sub-
stantially as and for the purpose specified.
2. The combination with the adjustable seats of Dog Carts and other like two
wheeled vehicles of an adjusting screw spindle travelling with the seat and working
through a stationary nut as and for the purpose specified.
3. The use in combination with the adjusting screw spindle travelling with the
seat or seats of a Dog Cart or other like two wheeled vehicle of an adjustable
spring binged stop for preventing the rotation of the said spindle as specified.
4. The mode of connecting or coupling the front and back adjustable seats of
Dog Carts and other like two wheeled vehicles by the aid of a self locking or
engaging spring catch and corresponding socket secured to the two seats respectively
and caused to interlock by the act of bringing the seats together as specified.
Dated this 22nd day of February 1886.
