PROVISIONAL SPECIFICATION.
Improvements in the Means of Adjusting the Load upon the Axle of
Two-wheeled Vehicles.
I, JOHN LANSLEY of London Street Basingstoke Hampshire, do hereby declare
the nature of this invention to be as follows
11
These improvements relate to the construction of two wheeled vehicles in such a
way that the body of the vehicle which contains the load or weight may be
moved backwards or forwards as required upon the axle so as to relieve the horse
from any extra work when travelling upon unlevel ground. By means of a spring
catch lock the body or cart, of my vehicle in the desired position, and by
releasing the catch I can move the body backwards or forwards by means of levers
or wheels and again lock it in position by means of the catch.
I can so regulate my improvements that in fixing my cart in the desired position
I also actuate the break.

COMPLETE SPECIFICATION.
Improvements in the Means of Adjusting the Load upon the Axle of
Two-wheeled. Vehicles.
I, JOHN LANSLEY of London Street Basingstoke Hampshire 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 and
accompanying drawings :-
My invention relates to improvements in the means of adjusting the load upon the
axle of two wheeled vehicles and comprises means for adjusting position of the body of
the vehicle according as the latter is ascending or descending an incline or travelling
In carrying my
over level ground, and break mechanism actuated by the driver.
Invention into practice 1 fix a rod at each corner of the under surface of the under
frame upon which rod moves a roller fixed to a bracket secured to the underside
of the body of the vehicle so that the said body may move forward or backward
upon the said rods.
I likewise attach to the centre of the under surface of such body an iron of Ų
or other suitable shape which travels over T iron secured to the central part of
a beam fixed longitudinally and centrally across the under frame aforesaid. This U
shaped iron is furnished with a perforation through its two branches so that when these
two perforations come opposite corresponding openings formed at suitable intervals
in the web of the T iron i.e. when the body of the vehicle shifts its position a
bolt is shot through these openings and secures the said body in the position
it occupies at the time. The said bolt is cynlindrical at its outer end and quadrangular
at its inner end which is secured in a bracket fixed at one side of the under
frame. A spring blade presses constantly against the inner end of this bolt and
tends to push it forward in order to lock the body of the vehicle in position. The
inner end of this bolt is provided with a slut in which engages one arm of a bell
crank lever whose other arm is operated by the break lever. At the rear end and
below the under frame is mounted a shaft carrying two break shoes and actuated
by means of a rod fixed at the rear end to a lever arm, keyed upon the said shaft
and at the front end to another lever arm fixed to the shaft of the break lever.
In order that my invention may be more fully understood I have shown the same

section of the under frame and of the lower part of the vehicle body. Fig. 2 is
an under side view of the under frame. Fig. 3 shows at an enlarged scale one of
the brackets carrying its roller. Fig. 4 represents likewise at an enlarged scale the
bolt locking mechanism, Fig. 5 being a plan thereof. Fig 6 shows modification of
the bolt locking mechanism, Fig. 7. being a plan of the inner end of the said
bolt. Like letters of reference indicate corresponding parts throughout the
figures.
In the accompanying drawings a represents the lower part of the body of the
vehicle and is the under frame upon which the said body moves when adjusting
the load. e are rods fixed to the under frame and upon which travels rollers a
carried by brackets e secured to the body a. is a U shaped iron also fixed to the
body a and arranged to travel over a T iron g. The U iron is perforated through
both branches so as to correspond successively with the various perforations of
the T iron at different positions of the body a and permit of the locking of the
said irons together by means of a locking bolt h. This bolt is operated by means of
a hell crank lever i carried by the under frame, the arm of the said lever entering
recess in the inner squared end of the locking bolt, and the arm 2 being
operated by means of the break handle or lever k." is a shaft carried by the
under frame and operating tho brake blocks through the lever arms man n
keyed respectively to the shaft. and the break lever shaft, and the connecting rod o.
is a spring pressing against one end of the bolt so as to force the said bolt
through the perforations in the T and U irons when in line with one another.
a
Fig. 6 and 7 show a modification of the locking apparatus in which the bolt
instead of being operated by a bell crank lever is operated by means of a cam or
projection bearing against an inclined part of the bolt h.
The cam ог
projection is carried on a shaft q' to which the break lever k is attached and presses
against the said part 2 as it is revolved by the break lever and so pulls back the bolt
into its unlocked position. The bolt again locks itself by means of the spring p as
aforesaid upon the lever being reversed. The operation of the apparatus is as
follows (According to my invention Iyoke in any suitable manner the horse to
the body of the vehicle so that the same can be shifted by the horse itself either
forward or backward as soon as the locking bolt is disengaged).
Upon travelling upon an incline the body a is shifted, by means of the roller d
travelling upon the rods c either backwards or forwards according to whether the
vehicle is going down or up an incline. For this purpose the bolt is unlocked by
pushing back the lever allowing the body a to slide over the frame b until the
perforations in the U iron comes opposite to another perforation in the T iron g
when the locking bolt is forced by the spring p through the said perforations upon
reversing the lever k.
Upon the lever being pulled back to unlock the bolt the said lever is moved
back still further so as by its action upon the lever arms m and n, and rod o to apply
the breaks to the wheels of the vehicle and thereby prevent the latter moving
when shifting the body a. The object of my invention is to greatly relieve the
horses labour and may be applicable to heavily laden vehicles of any description
provided with two wheels.
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 is :-
(1) In two wheeled vehicles the arrangement of mechanism whereby the body of
such a vehicle is free to move forward or backward according as the latter is
descending or ascending an incline and is locked in the position occupied at the
time of such ascent and descent by a spring bolt actuated by a hand lever operated
by the driver substantially as and for the purpose set forth and as shown in the
drawings.
(2) In two wheeled vehicles the combination of the mechanism above claimed for

constructed substantially as and for a purpose set forth and as shown in the
drawings.
(3) In two wheeled vehicles operating the break mechanism by use of a lever
likewise actuating the locking bolt as before claimed substantially as and for the
purpose set forth and as shown in the drawings.
