1 Alfred ReadING of 24 Kings Road Southsen in the County of Hants,
Coach Builder do hereby declare the nature of my Invention for "IMPROVED
MEANS OF RAISING AND LOWERING THE SHAFTS OF TWO WHEEL CARTS
to be as
follows:-
"
I provide an iron pin or bolt of about 4 of an inch in thickness, and of a
convenient length, and made with a collar or flange which fits into a brass plate
which is made with a suitably deep collar, which last mentioned collar is let into
the bottom of the body of the rart. Through the bottom of the body of the cart
the aforesaid pin or bolt is passed. The upper end of said pin or bolt is made square
so as to be easily tuanipulated by the occupier of the cart with a suitable wrench
or handle.
Parallel to, and in front of the axle of the cart I provide a spring of steel which
is connected with or attached to the bottom of the body of the cart by means of
the aforesaid pin, or bolt. Said pin or bolt is made with a square cut thread and
passes through a brass nut of about 1½" deep made with a corresponding thread,
and is fastened to the aforesaid spring by suitable bolts or rivets. At each end of
the aforesaid spring I fix with a screw and nut an iron standard, with a collar at
each end, which iron standard passes through the bottom of the body of the cart,
and is fastened to the extreme end of the shaft by a suitable screw and nut. The
shafts are fastened on the front of the body of the cart by means of an open head
or bolt of iron which acts as a bearing or hinge. By the several means herein-
before described the shafts may be raised or lowered to suit the height of the horso
to be used.

I ALFRED READING of 24 King's Road Southsca in the County of Hants
Coach-Builder do hereby declare the nature of my invention for IMPROVED
MEANS OF RAISING AND LOWERING THE SHAFTS OF TWO WHEEL CARTS and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
My invention relates to improved means of raising and lowering the shafts of
two wheel carts. In order that my said invention may be clearly understood
I refer to the accompanying drawings in which
Figure 1-Is a section of a portion of a two wheel cart taken through the
line A B figure 2.
Figure 2-Is a longitudinal section of a portion of a two wheel cart taken
through the line C D figure 1.
I fit or mount a screw of iron or other suitable metal a provided with a collar b
which collar fits into a brass or other suitable plate made with a deep collar
which last mentioned collar is let into the bottom of the body of the cart. Above
the collar b-the said screw is not threaded so that it may revolve freely in the
vertical bush or bearing c. The said screw passes through the bottom of the body
of the cart, and is operated by the handle d. Parallel to and in front of the axle
of the cart is a steel spring e which is connected to the bottom of the body of the
cart by means of the said screw a. At the ends of the said spring e the links or
rods ff are fixed with screws and nuts. These links or rods pass through the
bottom of the body of the cart and are connected or jointed to the rere ends of
the shafts of the cart by suitable screws and nuts. At a point g which may be
any convenient distance from the ends of the shafts, the said shafts are jointed 80
as to work as on a hinge. When the screw a is operated by means of the
handled the spring e rises or falls carrying with it the links or rods ff the
lower ends of which links or rods are connected to the ends of the said spring c.
When the said spring c is caused to rise or fall the shafts of the cart will have the
point g as a fulcrum or oscillating point and thus the front ends of the shafts may
be set to any desired height.
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 clain is
The combination and arrangement of the screw a, handle d, spring e and links
or rods ff substantially as and for the purposes hereinbefore described and
illustrated in the accompanying drawings.
