which I fasten a ratch plate. I cut several recesses to hold the lover handle in the
desired position. I make two sockets to receive axle. I fasten the two sockets, and
axle to bottom of body, with bolts. By the moving of the lever handle backwards
or forwards you raise or lower the shafts as desired. The body always remaining in
a level position.
In another modification of my Invention, on the lever extending backwards I form
an end extending forward, having a joint at the front end, which I attach by a bolt or
pin a rod of iron or steel, and carry the same up side of body. I make a screw on
the top of same, and fit a nut on screw. I square the end of rod and fit a wheel on
square or crank for turning. Thereby lowering or raising the shafts to any given
height.
Also I make a drag of iron or steel, I form a lever on axle of drag, on the end of
this lever, I attach a connecting rod, with an open joint and bolt, at the other
end form an open joint which I attach to the lever that raises the shafts up
and down, the whole thus working simultaneously I fasten the axle of drag
either on the bottom of body or stays that support the body, either by iron stays
or sockets.
I also reduce to a minimum the weight upon the Horses shoulders, by resting the
body on a square of four springs, attached to the body, by means of two cross stays,
off the cross springs. The weight thereby being taken entirely of the shafts, and
put on the axle.

COMPLETE SPECIFICATION.
Construction of Under-carriages and Adjustment of Balance of Two-
wheeled Vehicles and their Fittings.
I JAMES DAKERS of 24 Union Row and 7 Union Wynd Aberdeen North
Britain 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 relates to certain improvements in the construction, of two-wheeled

page_text: vehicles, and their fittings and is designed to render the same much more effective,
and durable than anything that has hitherto been constructed.
The first part of my invention relates to the removing the weight off the horses
back when going down hill, or vice versa.
This I propose doing as shown in Figure 1.
By making an axle D of iron or steel, I form a shoulder S at both ends of the axle,
screw ends of axle, and fit on nuts I make two levers H which I fit on ends of
square of axle at S extending backwards to the rear ends of shafts I make two
slot holes Ron ends of levers H I make an open joint I to receive the ends of
levers H pass bolt through slot hole and joint. I form a bolt on end of open joint
which passes through iron sockets on ends of shafts, screwed and fitted with nut. Ι
make a lever handle H and fit on to one end of axle, and extend it upwards to tho
Drivers seat, upon which I fasten a ratch plato E to the body N. I cut several
recesses to hold the lever handle in the desired position. I make two sockets to
receive axle D. I fasten the two sockets and axle D to the bottom of body N with
bolts. By the moving of the lever handlo H backwards or forwards you raise or
lower the shafts as desired, as showen by the shafts A and C the body always remaining
in a level position going up hill or down hill.
In another modification of my invention as shown in Figure 3 on the lever H
extending backwards I form an end extending forwards from S to R having a joint I
at the front end which I attach by a bolt or pin, a rod of iron or steel, and carry the
same up side of body N I make a screw on the top of same, and fit a nut on screw
I square the ends of rod and fit on a wheel or crank O for turning. Thereby
lowering or raising shafts B to any given height.
Also I make a drag K. K. of iron or steel as shown in figure 1 and 2 I fasten the
axle K K with iron stays G G to center of springs L L L form a lever F on center.
of axle D. The lever striking axle K K at center of arms, the whole thus working
simultaneously.
I also reduce to a minimum the weight upon the horses shoulders as shewn in
figure 1 and 2 by resting the body N on a square of four springs L L' by means
of the two cross stays M M upon the cross springs L L the shafts B being
attached to P. P.
Having thus described the nature of my said invention, and the manner in which
the same is to be or may performed I would have it understood that I do not confine
myself to the precise details of construction herein shewn and described, as the same
may be varied without departing from the main features thereof, but what I claim as
my invention and consider to be new is
Firstly. The levers H and axle D which are fastened to body N for the purpose
of raising and lowering the shafts either with or without drag as described in
figure 1 and 2.
Secondly. Working levers H H for raising and lowering Shafts by means of a
screw as shown in figure 1 and 2.
Thirdly. Slot hole or loose and open joint as shown in figure 4.
Fourthly, Drag K and lever F in combination with axle D as shown in
figure 1 and 2.
Fiftly. The method herein shown as in figure 1 and 2 applying and fixing the
springs L L to the body N by means of stays M either without drag or levers.
Dated this 6th day of May 1889.
