Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, JOHN BRADDICK PINNOCK of No 1 Old King Street, Bristol, in the County of
Gloucester, "Carriage Builder," do hereby declare the nature of my invention for
"IMPROVEMENTS IN TWO-WHEELED CARRIAGES," to be as follows :-
-
This Invention relates to Improvements in two-wheeled Carriages, whereby the
Shafts can be regulated, as to "Length & Height," so as to make any such Vehicle,
suited for "Horses of various Sizes," "the Seats," being kept "Level," by the rising
or lowering of the Shafts, which are also lengthened, or shortened, at the same time,
as required. "The Invention consists in fastening the Shafts, (at the front part of
the Body, of any such Carriage,) to a moveable "Cranked Fulcrum" of Iron or
other Metal, instead of to a "fixed, straight, "Fulcrum Pin," (as usual,) the
"Revolving of the Cranked Fulcrum," causing the lengthening, shortening, rising
or lowering of the "Front ends of Shafts,' as required. The back ends of
Shafts, being fitted with Steel Plates, which form a Groove, along which a Bolt, or
Pin, ("encased in India Rubber,") slides, the said Bolt, or Pin, serves to fix the
Shafts, to back part of Body, or to a Spring fixed to Body.

page_text: I, JOHN BRADDICK PINNOCK of N° 1 Old King Street, Bristol, in the County of
Gloucester, Carriage Builder, do hereby declare the nature of my invention for
"IMPROVEMENTS IN TWO-WHEELED CARRIAGES" and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement "that is to say ":-
"This Invention is intended to regulate the Shafts of any Two-wheeled Vehicle,
as to height or length, so that Horses of various Sizes, may be used in the same
Carriage, the Shafts being lengthened & raised higher at front part or shortened &
lowered, so as to suit the size of Horse in use, & keep the Seats of the Vehicle level,
with any size Horse." "This Invention consists "In fastening the Shafts, at the
front part of body (of any such Carriage) to a Moveable "Cranked Fulcrum" of
Iron, "(or other Metal,)" instead of, "To a fixed straight Fulcrum Pin," as usual,
"The Revolving of the Cranked Fulcrum," causes the alteration in length & height
of Shafts, at front ends of same. "The cranked fulcrum" is fitted to a metal plate
(which is screwed to the side of the body) this plate has a series of holes in it,
forming a circle, round the centre upon which the cranked fulcrum revolves, this
circle of holes, being screwed & there being 2 holes in cranked fulcrum, to match,
it follows, that with 2 nut-head screws, the cranked, fulcrum, can be securely fixed
to the flat plate in any required position. The cranked fulcrum revolves upon a
bolt which passes through the flat plate & also through a pipe eye, fastened under
bottom of body, making the whole very secure.
The back ends of Shafts are fitted with Steel-plates, which form a Groove, along
which a bolt, or screwed pin (encased in India Rubber) slides, the said bolt or pin
is fixed to each side of body at back part, or to each end of a Spring fixed to back
part of body.
The accompanying Drawings represent how I carry my invention into practice,'
Figure 1, Shows a two wheeled Carriage, with a revolving fulcrum, by which the
Shafts, can be fixed in 3 positions, A being for largest size Horse, B for a Medium
size, & C for smallest size. D shows the groove at back end of shaft, through'
which groove the bolt or pin, (encased in India Rubber) slides. Figure 2, Shows
"cranked fulcrum & plate fixed in position to correspond with A. in figure 1.
Figure 3, Shows them in position as in B.
4 Shows them in position as in C.
"
5 Shows "cranked fulcrum" & plate with nut head screws & also the
pipe eye, into which the "centre bolt" fits, upon which the "cranked fulcrum
revolves.
Figure 6, Shows the "cranked fulcrums" of any such two-wheeled Vehicle,
connected by a long bolt across the body, so that both Shafts can be worked at one
& the same time, in the same manner, as I have hitherto described them as being
worked separately.
Having now particularly described & ascertained the nature of my said
invention, & in what manner the same is to be performed, I declare that what
I claim is, Firstly "The cranked fulcrum" capable of revolving about a fixed centre,
whereby the Shafts may be lengthened, shortened, raised or lowered, as set forth
& substantially as shewn in the annexed drawings.

page_text: Secondly "I claim the appliances, I have described," Being the "cranked
fulcrums" (the same to work separately or combined,) the plates with circles of
holes, & the Steel plates, affixed to back ends of shafts, as & for the purposes
Bet forth."
