PROVISIONAL SPECIFICATION.
Improved Means for Adjusting the Seats or Platforms of Two
Wheeled Vehicles for Balancing the same.
I, WILLIAM VINCENT Arborfield Cross Reading Berks. Coach Builder, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a ready means of adjusting or moving
vehicle seats and the like objects, and the same is carried out as follows. In
applying this invention to cart seats I support the seat or seats so as, it or they
slide in grooves, backwards and forwards. Upon the under side of the seat I
attach a rack which engages with a racked quadrant or quadrants carried upon the
end of a bent pivotted lever provided with a spring or spring catch to keep it in
position. When this lever is pushed forward the quadrant acts upon the rack
upon the seat and moves the seat forward, one or more racked quadrants engaging
with corresponding racks under the seat, may be employed to shift the seat or other
object, backwards or forwards.

COMPLETE SPECIFICATION.
Improved Means for Adjusting the Seats or Platforms of Two
Wheeled Vehicles for Balancing the same.
I, WILLIAM VINCENT Arborfield Cross Reading Berkshire Coach Builder 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 this invention is to provide a ready means for adjusting or moving
vehicle seats and the like objects, and the same is carried out as follows. In
applying this invention to cart seats, I support the seat or seats so as it or they
slide in grooves, backwards and forwards. Upon the under side of the seat I
attach racks which engage with a racked quadrant or quadrants carried upon and
secured to a rod having bearings in the side of the vehicle. To one or both ends
of this rod is attached a straight or bent lever provided with a spring or spring
catch to keep it in position. When this lever is pushed forward the quadrants act
upon the racks upon the seat and move the seat forward. One or more racked
quadrants engaging with corresponding racks under the seat may be employed to
shift the seat or other object backwards or forwards.
Referring to the annexed drawings:-
:―
Figure 1 is a side elevation of a vehicle fitted with my invention..
Figure 2. sectional end elevation of same.
Figure 3. side elevation of a modified arrangement of my invention.
a is the seat running in grooves in the sides of the vehicle c; d, d, quadrant
racks secured to and carried by spindle j; e, e, racks attached to the seat a and
engaging with the quadrant racks d, d. A handle or lever f is attached to and
operates the spindle j. This handle may be straight or bent to suit the form of
vehicle, and is provided with a spring catch piece as shown, and a perforated
plate; a pin attached to the small lever g enters the holes h in the plate i. A
spring is employed between the lever ƒ and g and by this means the handle may
be retained in the desired position. The action is as follows -When it is desired
to move the seat or platform a the handle f is operated in the right direction, this
q
[177

page_text: causes the quadrant racks d, d, through the medium of the spindle ; to move, and
thus causes the seat or platform a to slide backwards or forwards according to the
direction in which the handle f is moved. The lever or handle f is then retained
in position by the pin or the small lever g engaging in the holes h in the perforated
plate i.
Referring to Figure 3, in this case the quadrant racks d have a prolongation k.
The handle is secured to a spindle ; secured to this spindle and on the inside
of the cart or vehicle is a rod or lever m. This rod m is movably connected to
the lever n at P, which is in turn movably connected to the prolongation k at o.
It will be seen that owing to the difference in distance between the points 1 & p,
and ; & o, a small movement of the handle f will produce a proportionately
greater movement of the quadrant d and thus the seat is readily adjusted.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what I
claim is :-
1. The combined arrangement and construction of the various parts substantially
as described.
2. In means for regulating seats in vehicles and platforms of milk and other
carts, a seat provided with racks engaging with and operated by quadrant racks
attached to a spindle and operated by a lever having a spring catch-piece engaging
in a perforated plate all in combination.
