Improvements in and connected with Bicycles and Tricycles.
I, WILLIAM FARLEY HILLS, of No. 316 Stanstead Road, Catford, in the
County of Kent, Gentleman, do hereby declare the nature of this invention to be
as follows:-
My invention refers more particularly to bicycles and tricycles and to attach-
ments therefor which will permit of a machine being either used as a single
bicycle or tricycle or as a tandem bicycle or tricycle, and part of my invention is
applicable to bicycles and tricycles generally.
I provide an additional framework having a lower bracket with cranks and
cbain wheel or other gear for transmission of motion, a saddle or seat, a handle
bar or handles and a socket into which the front wheel of a bicycle can be inserted
and mounted in the ordinary manner. The rear part of this framework is con-
structed in such manner as to be fixedly and easily secured to the frame proper of
the machine. When chain and chain wheels are used as the means of conveying
the motion from the cranks to the hind or driving wheel, I construct a detachable
chain wheel or merely a rim which is capable of being easily attached to and
detached from the chain wheel on the crank shaft of the bicycle or tricycle proper.
The additional frame is provided with an upper adjustable tube which is pivotted
or hinged to the socket and attached to the vertical tube by means of a screw
coupling, when the front rider is a man or a woman wearing rational dress. If the
frame is required to be made open, the screw coupling on the pivotted tube is
released, the latter is allowed to drop and the screw coupling is secured to a
screwed socket or the like on the lower tube of the framework. The pivotted
tube may also be made to be capable of being easily removed and in that case it
may be constructed in such manner as to form an inflater, having a plunger,
suitable valves and connections. By this means the necessity for a separate
inflater is done away with. This part of my invention is also applicable to
bicycles and tricycles generally.

İ, WILLIAM FARLEY HILLS, of 316 Stanstead Road, Catford, London, 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 bicycles and tricycles, to motor cycles and the like.

page_text: The
The object of the invention is to alter a cycle made to carry one person into a
cycle capable of carrying two persons, with a little modification the invention can
be used to convert a cycle for two persons into one to carry three and so on.
invention consists of removing the front wheel of the cycle together with the
front wheel fork for same, a portion of the head of the cycle and the handle bar.
In place of the pieces removed a supplementary frame-work is fixed to the cycle
and to the front of this frame-work the before mentioned parts are re-adjusted.
The supplementary frame-work may be of any suitable design or shape and is
preferably attached to the cycle at the head of same and also at or near the bottom
bracket. A portion of the frame-work is capable of alteration, as hereinafter
described, so that it may be used by a lady or a gentleman.
A second fixed handle bar is fitted in place of the one removed. The supple-
mentary frame-work is provided with a Tor L pin to carry a saddle or seat and
also with pedal cranks and chain wheel for assisting in driving the cycle. The
chain from this chain wheel is carried back and drives an extra chain wheel or
ring which is fitted by means of lugs, screws or any other simple device to the
chain wheel on the original machine. By preference this chain wheel or ring
consists of a circular rim provided with the usual chain teeth and with lugs
projecting laterally of such length as to pass through and against the spokes of
the chain wheel on the original machine and engage with catch ring on the opposite
side of same, as shewn in Figs. 4, 5, 6.
I will now describe my invention with reference to the accompanying drawings,
in which :-
Fig. 1 shews a diagrammatical elevation of an ordinary bicycle, in full lines,
and the supplementary frame-work in dotted lines.
Fig. 2 shews an elevation of the frame and machine arranged for carrying two
riders.
Fig. 3 shews an enlarged sectional elevation of most of the supplementary
frame, showing details of various fittings for the joints.
Fig. 4 shews an elevation of a special chain or sprocket wheel which I
preferably employ with my supplementary frame.
Fig. 5 shews a half sectional end elevation of Fig. 4.
Fig. 6 shews a detail sectional view of the method of connecting the two parts
of the double chain wheel together by means of the lugs and screws before
mentioned.
Referring to the supplementary frame:
a is a portion of the frame which somewhat resembles an acute angle, curved at
its apex, and this portion intersects other portions of the frame in two places,
namely, at x and y.
This specially arranged portion provides (1) a second saddle pillar b and
(2) enables the supplementary frame-work to be altered at c so as to allow the
bicycle to be ridden by either a lady or a gentleman.
Referring to Fig. 3, c is one end of the portion a, which is internally screwed to
receive a screwed nipple projecting from the end of the top rod or cross-bar d of
the frame, when the machine is to be altered to suit a lady rider, and the bar d is
provided with a hinge or other suitable joint f for the purpose. See dotted lines
Fig. 3. The other end of the bar d is screwed with an internal thread to receive
the nipple by which this end is attached to the rest of the supplementary frame.
For purposes of adjusting the bar d the following method is employed. 9 is a
portion of the supplementary frame which is attached to the head of the original
machine. The sleeve 92 passes up through the head g' to which it is fixed by any
simple means. At the upper end of sleeve g2 the fixed handle bar is attached.
g also embraces the upper part of the acute-angled portion a of the supplementary
frame; as shewn in Fig. 3. 9 is also made to receive an externally screwed
nipple, the screw thread of which engages with internal screw threads at the
portion and bar d.
9.
The nipple is so constructed as to allow of its being screwed from outside by

page_text: means of a sleeve k, same being connected with the inside nipple h by an internal
circumferential ring 1.
Referring to Figs. 4, 5, and 6. m is the usual' chain or sprocket wheel fixed on
the original machine, to one side of which an extra chain or sprocket wheel n is
fixed which preferably consists merely of a rim provided with teeth on its
periphery. This rim n is provided with a number of laterally projecting lugs o,
which project towards and through the spokes of the chain wheel m, and engage
at their ends with a catch or lock ring p provided with recesses o¹ corresponding in
number to the lugs o. The method of fastening the extra chain wheel or rim n is
as follows:-
The rim n is placed against the chain wheel m so that the heads of the projecting
lugs o engage with the recesses o' of the catch ring p. The catch ring p is then
turned a short distance to the right or left, which movement brings a solid portion
of the ring p under the lugs o, and is prevented from returning by a suitable spring
as that shewn at r Fig. 4."
The lower part q of the supplementary frame is provided at either end with a
knuckle or other suitable joint, to allow of the bar being fastened or unfastened
easily and quickly. If preferred, more than one bar may be used in place of bar y.
It will thus be seen that I have designed a cycle frame which is capable of being
altered at will, and with facility to carry one, two, or more riders. If necessary
the rod or cross-bar d of the supplementary frame may be taken out and used in
an emergency as an air-pump.
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 convertible cycle the special supplementary frame, a portion of which
provides a second saddle pillar, and also means for altering the cross-bar of said
frame to allow the bicycle to be ridden by a lady, said cross-bar being fitted with
a hinge-joint for this purpose, as herein described and set forth. Said frame being
provided with the usual crank axle, chain gear, pedals and the like.
(2.) In a convertible cycle, the means as shewn, for connecting the top cross-
bar of the frame to the portion g, or to the part c, as shewn, and for the purposes
herein described and set forth.
(3.) In a convertible cycle the combination of the matter contained in the two
previous claims, with an extra chain or sprocket wheel preferably in the form of a
plain rim provided with laterally projecting clips or lugs the ends of which engage
with a locking ring, and the means as shewn for preventing said locking ring from
slacking back, whereby a double chain or sprocket wheel is obtained for carrying
an extra chain, as shewn, and for the purposes herein described and set forth.
Dated this 27th day of February 1897.
