PROVISIONAL, SPECIFICATION.
Improvements in Sliding or Moveable Seats for Two-wheeled Carts.
I, JOHN GEORGE HARRISON 49 Summerfield Crescent Birmingham Manager
of Works do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a convenient arrangement for moving
the seats of two-wheeled carts on slides, and holding them securely in any desired
position.
On the sides of the cart I affix slides of a special and suitably shaped metal, and
drill therein holes of such a size and at such a distance as suits my purpose.
In or near the centre of the seat I arrange a socket or tube in which a spindle
works perpendicularly, and to the lower end of this spindle I couple the one end
of two short chains, while at the other ends of each chain 1 joint a rod or bar, of a
size to engage with the drilled holes in the slides on the sides of the cart, and which
said rods or bars are carried in bearings to work horizontaly underneath the cart
seat as the spindle in the perpendicular socket is worked within the socket.
On the top end of the spindle which works within the perpendicular socket
I joint a handle or pull, and on each bar or rod I fit a spiral spring, so arranged
that when the handle or pull is raised the springs are compressed and the rods or
bars drawn towards the centre of the seat, then when the handle or pull is released
the rods or bars are forced outward toward the sides of the cart and engage with
the holes drilled in the slides on the sides thereof, so holding tlie seat firmly in a
given position until the handle or pull is again raised, which action withdraws the
rods or bars from the holes in the slides in which they have been engaged, so
allowing the seat to be moved, when the handle or pull being released the rods
or bars will engage in other holes in the slides on the sides of the cart, thereby
holding the seat in its new position.
Near the lower end of the perpendicular socket I arrange rollers, so that the
short chains before mentioned may travel smoothly from the horizontal to the
perpendicular when the handle or pull is raised, and in the opposite direction when
the handle or pull is released.
At each end of the seat I arrange guides which work on the slides on the sides
of the cart and insure the seat moving squarely and truly with the sides of the cart.
The guides at the front of the seat serve as bearings for the outer ends of the
rods or bars, and all the guides are fitted with rollers, so that the seat will travel
freely, and without friction on the slides on the sides of the cart.

Improvements in Sliding or Moveable Seats for Two-wheeled Carts.
I, JOHN GEORGE HARRISON 49 Summerfield Crescent Birmingham Manager
of Works 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:-
The object of my invention is to provide a convenient arrangement for moving

page_text: 1
the seats of two-wheeled carts on slides, and holding them securely in any desired
position.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which Figure 1
is a longitudinal sectional elevation through a seat having my device attached
thereto, and Figure 2 is an inverted plan of same.
On the sides of the cart B 1 affix slides C of a special and suitably shapod
metal, and drill therein holes of such a size and at such a distance as suits my
purpose.
In or near the centre of the sent I arrange a socket or tube A in which a
spindle a works perpendicularly, and to the lower end of this spindle O and O'
I couple the one end of two short chains while at the other end of each chain E
and E1 joint a rod or bar F and F¹of a size to engage with the drilled holes in
the slides on the sides of the cart, and which said rods or bars are carried in
bearings H to work horizontaly underneath the cart seat K as the spindle in the
perpendicular socket is worked within the socket.
On the top end of the spindle which works within the perpendicular socket
I joint a handle or prill M, and on each barior rod I fit a spiral spring N and N¹
so arranged that when the handle or pull is raised the springs are compressed and
the rods or bars drawn towards the centre of the seat, then when the bandle or
pull is released the rods or bars are forced outward toward the sides of the cart
and engage with the holes drilled in the slides on the sides thereof, so holding the
seat firmly in a given position until the handle or pull is again raised, which action
withdraws the rods or bars from the holes in the slides in which they have been
engaged, so allowing the seat to be moved, when the handle or pull being released
the rods or bars will engage in other holes in the slides on the sides of the
cart, thereby bolding the seat in its new position.
Near the lower end of the perpendicular socket. I arrange rollers S and St, so
that the short chains before mentioned inny travel smoothly from the horizontal to
the perpendicular when the handle or pull is raised, and in the opposite direction
when the handle or pull.is released.
At each end of the seat arrange guides T and T¹ which work on the slides
ou the sides.of the cart and insure the seat moving truly and squarely with the
sides of the cart.
The guides at the front of the seat serve as bearings for the outer ends of the
rods or hare, and all the guides are fitted with rollers., so that the seat will travel
freely and without friction on the slides on the sides of the cart.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim ie
First. The combination of parts as herein described, and secondly the handle
or pull with the spindle working within the perpendicular socket, and the chain
connections passing over rollers from the lower end of the handle spindle to the
rods or bars on which the springs work.
