COMPLETE SPECIFICATION.
Improved Arrangement of Appliances for Adjusting Cart Bodies on
their Axles.
I, JOHN CHALMERS, of High Street, Red Hill, Surrey, 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:-
This invention has for object to fit to the body of a cart and to the under or to
shaft frame certain appliances in a certain manner, so that by a movement of a side
lever having its fulcrum at the centre of the shaft front cross bar, or splinter bar,
the body can be set for balancing purposes according to the position of the load,
said invention being also applicable for ready adjustment in travelling up or down
a hill.
If going up hill, an additional weight thrown on a horse's back gives
greater power for drawing purposes. In going down hill, the preponderance of
weight should be at the rear of the cart.
The invention will be fully understood by referring to the annexed drawings.
Figure 1 side elevation of cart body.
Figure 2 under plan of body.
Figure 3 upper plan of shaft frame.
Figure 4 transverse section of body and shaft side rails.
A is the body with under part of side rails B, B, slotted as at C, C, each slot
being provided with a plate for the rollers D, D, on the shaft frame E to bear
against, the rollers being partially enclosed in the slots.
The rollers D, D, are in journals F, F, affixed to the shaft frame side rails,
the inner ends of the axles being within staple like links H, H, which prevent
the body jumping while travelling, or leaving the shaft frame, should the cart be
tipped up.
I is a hand lever in a rack J for locking it; the lever I is pivoted to the body
by a cross bar K the centre part between the body side rails having another lever L
connected by a rod M to the shafts bar or splinter bar N, from which the back-
ward or forward motion of the cart body is obtained.
Figures 5, 6, and 7 represent the invention as applied to a "well" bodied cart
for a movement of the body upon the shafts, or shaft frame E. In this arrange-
ment, I attach the rollers D, D, by strap plates G, G, to the under side of the
shafts by which the shafts are held at their respective distance apart, the hand
lever I being pivoted to the body, as in the previously described method.
I am aware that cart bodies have been shifted by a hand lever for adjustment
of weight of load over the axle, therefore I lay no claim to any known system, or
appliances for the purpose.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that
what I claim is :-
1. The arrangements of appliances herein before described, and as shown on the
annexed drawings, for the adjustment of the load weight in a cart over the axle,
the operation for adjustment being centrally, and from the shafts bar as set
forth.
2. Arranging jointed rods between the centre of a shaft frame, and the centre of

page_text: a cross bar on cart body for parallel motion of said body when actuated from a
side handle, as described and shown.
