I JOHN JOICE of Winchester Street, Basingstoke, in the County of Hants, Coach
Builder do hereby declare the nature of this invention to be as follows:-
These improvements have reference to those carriages in which it is desirable to
provide for changes of relative positions of the body or other portions, such as the seat
relatively to the axle, or so that the weight of the vehicle and its occupants may be
adjusted to "balance" correctly and to relieve undue strain on the animal drawing or
for bringing the brakes to bear on the wheels.
This relative movement of the body of the cart or vehicle relatively to the axis or of
the seat; or other portions in a like manner, I effect by applying under the seat or to
the under part of the body or to the portions to be shifted, a rack or a pair or other
number of racks and below or above these is arranged an axis on which is a corre-
sponding tooth pinion or pinions engaging the rack or racks. This axis is operated
by means of a handle conveniently arranged at the side of the vehicle so as to be
readily accessible by the driver or others for shifting the seat, body or parts without
leaving or rising from their place of necessity, said handle operating a kind of ratchet
brace connection to the axis."
If so required by the character of the vehicle the operation of the balancing axis
may be effected through the intervention of gear or similarly if the distance from the
hand is too great for direct leverage.
Change of direction of motion either to move the body or seat forward after move-
ment backwards or vice-versa is effected by rotatory movement to the lever handle which
brings a projection at end of the lever over one or other of a pair of stop pieces hinged
to a stem from a split socket which grasps the axis and holds between its jaws the stud
wheel which the stop pieces alternately operate as the direction of motion is changed.
These stop pieces are pressed from operation by the projection and to their work by

page_text: an internal spring. When the lever is rotated to a mid position and the spring action
acts on both bits the stud wheel is held fast and the axis also, fixing the body, seat or
parts at its or their then position or keeping the brake or brakes on or off the
wheels.

Figure 1 is a front elevation of the invention applied to the underside of a dog cart
seat the parts of the cart being shown in section.
Figure 2 is a side elevation of the same.
Figure 3 is an underside view of the same shewing the parts as seen from below the
seat.
Figure 4 is a front view and Figure 5 a side view of a detail of the invention being
the ratchet ends of the ratchet lever and ratchet ends of the cross axis carrying the
rack wheel for moving the seat.
The movement of the seat a is effected by means mainly of parts applied under the
same that is to say under the seat a or to the underpart of the body or to the portions
to be shifted, a rack a' or a pair of racks a¹, a¹ or other number of racks and below

page_text: (or above) these is arranged an axis 6 on which is a corresponding tooth pinion 6' or
pinions, engaging the rack or racks a', a'. This axis 6 is operated by means of
a handle & conveniently arranged at the side of the vehicle so as to be readily accessible
by the driver, or others for shifting the seat a, body or parts without leaving or rising
from their place of necessity, said handle 63 operating a kind of ratchet brace connection
to the axis.
If so required by the character of the vehicle the operation of the balancing axis
may be effected through the intervention of gear or similarly if the distance from the
hand is too great for direct leverage.
Change of direction of motion either to move the body or seat a forward after
movement backwards or vice versa is effected by rotatory movement to the lever handle 6*
which brings a projection 63 at one end of the lever 62 over one or other of a pair of stop
pieces 6*, hinged to a stem from a split socket 6' which grasps the axis 6 and holds
between its jaws the stud wheel 6 which the stop pieces 64, 64 alternately operate as
the direction of motion is changed. These stop piéces 6ª, 6ª are pressed from operation
by the projection 63 and to their work by an internal spring b. When the lever b is
rotated to a mid position and the spring action acts on both bits 64, 64 the stud
wheel 6 is held fast and the axis also, fixing the body, seat or parts at its or their then
position or keeping the brake or brakes on or off the wheels.
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 claim is :-
The combination or arrangement and use of parts of ratchet mechanism for effecting
the movements of the seat or other part of a carriage relatively to other parts thereof
substantially as and for the purposes set forth.
Dated the 18th day of October 1888.
