PROVISIONAL SPECIFICATION.
Improvements in Fastenings for Adjustable Seats of Dog Carts
and other such Vehicles.
I, ARTHUR BARNWELL, of 21, James Street. Rugby, in the County of Warwick,
Carriage Builder, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object improvements in fastenings for adjustable
seats of dog carts and other such vehicles by which 1 provide a simple cheap
and effective fastening which firmly retains the seat in the required position
and at the same time can be readily and quickly adjusted as required.
In carrying my invention into effect I form a cavity or recess in the under-
side of the seat or bearer at each end and over this cavity I screw an angle
plate to which a band spring is rivited or bolted in such a manner that the
spring is free to work in the cavity. This angle plate is slotted to allow of a
rounded nose which is attached to the spring to project through on the under-
side.
Along the sides of the cart 1 attach an angle strip having its edge which
is vertical notched with notches which are shaped to receive the before men-
tioned nose of the spring and these angle strips may be so formed as to attach
to a ledge in the cart or to the sides of the cart itself.
A second plate is attached to the underside of seat below the other plate
and has its bearing against the underside of the slotted angle strips thus
preventing the seat from tilting.
For adjusting, it is only necessary to push the seat in the required direction
sufficiently to cause the shaped sides of the nose to rise up the shaped sides
of the notches against the resistance of the spring, the seat being automatically
secured at each notch it passes.

Improvements in Fastenings for Adjustable Seats of Dog Carts
and other such Vehicles.
I, ARTHUR BARNWELL, of 21, James Street, Rugby, in the County of Warwick,
Carriage Builder, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:—
My invention has for its object improvements in fastenings for adjustable
seats of dog carts and other such vehicles by which I provide a simple cheap

page_text: and effective fastening which firmly retains the seat in the required position
and at the same time can be readily and quickly adjusted as required while
no room whatever is taken up under the seat in the body of the vehicle by
the mechanism.
In order that my invention may be clearly understood and more easily
curried into practise I have appended hereunto a sheet of drawings upon which
I have fully illustrated the nature of my said improvements.
Figure is a cross section through the extreine end of the seat shewing
the mechanism in elevation.
Figure 2 is a cross section through Figure 1 on the line 1-2 looking in
direction of arrow.
Figure is a similar cross section to Figure 2 but on the line 3-1 and
looking in the reverse direction as shewn by arrow,
Figure 4 is a plan of Figure 1 the seat being indicated by dotted lines for
the purpose of shewing the mechanism.
In carrying my invention into effect I form the envity or recess at in the
underside of the seat. A preferably at the one end of the sent only ¿e, the end
occupied by the driver and over this cavity the angle plate B is screwed to
the seat A to which angle plate the end of the band spring is rivited at din
such a manner that the end is free to rise in the cavity a while the said
angle plate is slotted at 2 to allow the rounded nose which is attached to
the spring c to project through on the underside to engage with the notches
formed on the angle plate which is secured by any suitable means such as
the ledged to the side of the eart E and is continued along the side E for the
full length of the travel of the seat. The angle plate B is mounted to run
on rollers while a second angle plate is attached to the underside of the
first mentioned plate D or seat A and has a projection which upon the sent
having a tendency to til bears against the underside of the angle plate D and
thereby prevents any such action taking place.
A sliding hot having spring is provided for the purpose of sliding the
nose of the bolt over the nose of the spring catch to prevent any possibility
of the seat being inndvertently moved when such movement is not required
while for adjustment it is only necessary to withdraw the boli. F by the
button and push or pull the seat in the required direction sufficiently to
cause the rounded sides of the nose to rise up the sides of the notches d
against the resistance of the spring the sent being automatically secured in
position by each notch it passes where it can be securely bolted by pressing
the bolt until its nose is over the nose cas before described.
The reverse end of the seat may or may not be provided with a similar
arrangement or may have similar angle iron supports without a catch or roller
arrangement or may be allowed to simply rest on the usual ledge formed on
the side of the cart for the purpose.
I do not confine myself to the exact form or shape of spring catch or holt
arrangement angle iron supports here shewn the principal feature of my inven
tion being that when unlocked the seat is capable of being adjusted in position
by means of bodily pressure without using the hands for the purpose in which
position it can be securely locked by means of a slight pressure being brought
to bear upon the projecting head of a bolt.
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
1 claim is
1st The combination of parts by which the position of the seat is capable
of being adjusted by bodily pressure without the necessity of using the hands
and at the same time is automatically retained in such position and in such manner
that it can be securely locked against further movement substantially as set i
forth.

the combination of a notched rail fixed to the cart upon which the seat is
made to slide a spring nose attached to said seat and engaging with the afore-.
said notches and a locking bolt all substantially as and for the purpose herein
set forth.
