Complete Specification Left, 1st May, 1894-Accepted, 2nd June, 1894
PROVISIONAL SPECIFICATION.
Improvements in Carriage Shaft Fulcrums.
I; JOHN WESLEY CLIFT of Hillside, Wellington in the County of Salop,
Carriage Manufacturer do hereby declare the nature of this invention to be as
follows:-
In place of the ordinary pivot bolt, or prod, forming the fulcrum, by which the
shaft of a two wheeled vehicle is usually attached to the body: I substitute a metal
stay having a convex end upon the rounded upper surface of which the shaft is
fastened, by means of a clip and coupling bar. The inner, or shaft, side of the
coupling bar being of a greater convexity than the stay: allows the shaft to bend
freely with the motion of the horse by rocking upon the stay.
To protect the wood forming the shaft from wear a friction plate is interposed
between it and the convex surface of the stay.
Dated this First day of August 1893.
COMPLETE SPECIFICATION.
Improvements in Carriage Shaft Fulorums.
I, JOHN WESLEY CLIFT of Hillside, Wellington in the County of Salop,
Carriage Manufacturer 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 :-
In the accompanying drawings
Fig. 1 is a side view of the front corner of the body in a two wheeled vehicle
with a portion of the shaft "S" showing my method of attaching the shaft when
it is constructed to pass through the toeboard and inside, the body.
Fig. 2 represents the same viewed from underneath.
Figs. 3 and 4 are an under and side view respectively of a portion of shaft and
stay showing my method of attaching the former to a two wheeled vehicle when it
is constructed for the shafts on either side and without entering the body.
In place of the ordinary pivot bolt or prod forming the fulcrum by which the
shaft of a two wheeled vehicle is attached to the body I substitute a metal stay A
(or A¹) having a convex end upon the rounded surface of which the shaft is
fastened by means of a clip C and coupling bar B. The inner or shaft side of the
coupling bar being of a greater convexity than the stay allows the shaft S to bend
freely with the motion of the horse by rocking upon the stay.
To protect the wooden shaft from wear interpose a friction plate P between
the shaft and the convex stay. This plate is screwed to the shaft and may be
furnished on its front end with a hook for attaching the trace of the harness.
When the shafts are constructed to pass inside the body, the stay travels under the
shaft in a longitudinal direction as shown in Figs. 1 and 2. When the shafts do
not enter the body a different shape of stay is required as shown in Figs. 3 and 4.
This crosses the shaft either above or below in a lateral direction and is
continued at one or both ends as required for bolting against or underneath the
body.

page_text: 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
1. In a two wheeled vehicle the fixing of the shaft against the convex surface of
a stay or plate upon which it may have the rocking motion substantially as
described.
2. The use for this purpose of a metal stay or plate having a convex surface
and which may be placed either below or above the shaft: in combination with
the coupling bar B. (which may be half round or triangular in section) and a
friction plate P secured to the shaft by means of a clip or bolt substantially as
<<described.
