Convertible Cycle.
We JANE CARTWRIGHT WOODBRIDGE of Priory Road High Wycombe in
the County of Buckingham Ironmonger and JOSEPH WATKIN MONEY of
Hughenden Road High Wycombe aforesaid Cyclemaker 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:
The object of the invention is a mechanical device for adapting a cycle to the
requirements of both sexes and is applicable to different forms of cycles or
velocipedes viz. :-Single, tandem triplet and other safety bicycles and to
tricycles.
In describing the said invention reference is made to the accompanying
drawings.
°
Fig. 1 (Sheet 1) shews side elevation of a single bicycle frame shewing the
undermentioned telescopic tube A in two desired positions.
We take two pieces of steel tube or other suitable material of proper diameter
strength and length to construct the telescopic tube A. At the extreme ends of
the telescopic tube A we form knuckle or lug or other suitable joints to work on
pins A1 and A2 or other suitable joints. A steel clip G is braized to the top end
of the lower portion of the telescopic tube A and to this clip G is fitted a bolt or
screw B. The action of loosening this bolt or screw B releases the said clip or lug G
and allows the top portion of telescopic tube A to slide into the lower portion of
same. The said telescopic tube A is attached at the lower end by means of a pin or
bolt A 2 to adjustable sliding clip or lug C which is allowed to slide up and down
the main seat pillar supporting or main down tube F by releasing the bolt or
screw D. The said telescopic tube A is attached at the top end to adjustable
sliding clip C 2 by a pin or bolt A 1. The adjustable sliding clip or lug C 2 may
be made a fixture if desired but otherwise can be worked in the same manner as
adjustable sliding clip or lug C. The telescopic tube A. can be moved to any desired
position by loosening the clip or lug and bolts or screws A. 3. B. and D. The
adjustable sliding clips or lugs C and C 2 can then be moved up and down the seat
pillar supporting tube F and ballhead tube E with freedom. To fix the telescopic
tube A in the position desired the clip or lug and screw or bolt A. 3 and D arc
screwed up tight to grip the clips or lugs C and C 2 to the seat pillar supporting
or main down tube F and ballhead tube E and the bolt or screw B of the clip or
lug G is screwed tight to grip the upper portion of telescopic tube A.
In a convertible cycle it is very desirable to have the main seat pillar supporting
or main down tube F several inches longer or higher for a tall rider than for a
short rider and to attain this object we insert and braize a piece of steel tube or
other suitable material of suitable diameter strength and length H 1 into socket G1
of bottom bracket G 2. To the top end of this tube H 1 is fixed a clip or lug H
which grips the seat pillar supporting or main down tube F at the lower end by
means of the screw or bolt h. The steel tube H 1 is made of sufficient internal
diameter to allow the seat pillar supporting or main down tube F to move up and
down with freedom. The desired movement of this tube F is governed by a small
slot and pin device shewn in Figures 1 and 2 (Sheet 2). 1 shews a slot of suitable
length and breadth cut in outer steel tube H 1. A small stud 2 is screwed into

page_text: the seat pillar supporting or main down tube F and made to work up and down in
slot 1 thus insuring the proper movement. The movement of the tube F is als.
governed by the slot device shewn in Figure 3 (Sheet 2). The vertical back
fork F1 is attached in the usual way at the top but has a slot 4 cut in the lower
end to move freely on screw or bolt 5. The horizontal back fork F 2 has a solid
end 3 which receives the back wheel of the cycle and through this end a hole is
drilled and tapped in the convenient position shewn to receive the said screw or
bolt 5. When the screw or bolt 5 is released it allows the vertical forks F 1 to be
moved to desired positions.
Having now particularly described our said invention and in what manner the
same is to be performed we declare that what we claim a Patent for is
A device for converting cycles including singles tandems triplets or tricycles
comprising two telescopic tubes one running horizontally from ballhead to seat
pillar supporting or main down tube and fitted with sliding adjustable clip or lugs
and bolts or screws as described and the other running vertically from bottom
bracket and being the before mentioned seat pillar supporting or main down tube
also fitted with clips or lugs and bolts or screws to enable same to be moved
and fixed and thus giving a perfect lady's or gentlemans cycle of various heights
as desired.
Dated this 23rd day of January 1897.
