Improvements in Attachments for Connecting Together Two
Safety Bicycles.
We REUBEN REEVE of Queen Street, Lymington, in the County of Hants, and
ARCHIBALD FLETCHER of 3 Victoria Buildings, Pokesdown, in the county
aforesaid Cycle Agent, do hereby declare the nature of this invention to be
as follows:
Our invention relates to an improved attachment for connecting two safety
bicycles together side by side to form a sociable quadricycle, and it consists of five
essential parts. First a cross bar carrying adjustable clamp sockets at its ends
adapted to embrace and be fixed to the steering sockets of the cycles one of the
said clamp sockets being made adjustable axially with respect to the bar to enable
the axial positions of the said clamp sockets to be varied to suit the slope or rake of
the steering heads of the two machines. Secondly a rod having arms pivotted to
its ends the said arms carrying clamp sockets adapted to embrace the adjacent
members or prongs of the forks carrying the steering wheels, the object. being to
couple the said steering forks so as to ensure their synchronous movement and to
enable either or both riders to steer. This rod is preferably made adjustable in its
length. Thirdly a cross bar carrying snugs at its ends, the said snugs having holes
or eyes adapted to fit over the adjacent ends of the axles of the driving wheels of
the cycles and to be locked thereto by the axle nuts thereon. This bar carries two
snugs and it is preferably made telescopic in its length, and fourthly and fifthly
of two stays each connected at one end to one of the snugs on the cross bar
connecting the axles of the two cycles and each connected at its other end-by
means of a clamp socket-to the top or upper member of the rear part of the
frames carrying the driving wheels of the cycles. These stay rods may be crossed
if desired and they may also be made adjustable in length so that they engage with
the rear part of the frames of the cycles as near to the saddles as possible.

Improvements in Attachments for Connecting Together Two

We, REUBEN REEVE, of Queen Street, Lymington in the County of Hants and
ARCHIBALD FLETCHER, of 3, Victoria Buildings, Pokesdown, in the county
aforesaid, Cycle Agent, 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 :-
Our invention relates to an improved attachment for connecting two safety
bicycles together side by side to form a sociable quadricycle, and it consists of five
essential parts:-First of a cross bar carrying adjustable clamp sockets at its ends
adapted to embrace and be fixed to the steering sockets of the bicycles, one of the
said clamp sockets being made adjustable axially with respect to the bar to enable
the axial positious of the said clamp sockets to be varied to suit the slope or rake

to its ends the said arms carrying clamp sockets adapted to embrace the adjacent
members or prongs of the forks carrying the steering wheels, the object being to
couple the said steering forks so as to ensure their synchronous movement and to
enable either or both riders to steer. This rod is preferably made adjustable in its
length. Thirdly of a cross bar carrying snugs at its ends, the said snugs having
holes or eyes adapted to fit over the adjacent ends of the axles of the rear driving
wheels of the bicycles and to be locked thereto by the axle nuts thereon. This bar
carries two snugs and it is preferably made telescopic in its length, and fourthly
and fifthly of two stays each connected at one end to one of the snugs on the
cross bar connecting the axles of the two bicycles and each connected at its other
end-by means of a clamp socket-to the top or upper member of the rear part of
the frames carrying the driving wheels of the bicycles. These stay rods may be
crossed if desired and they may also be made adjustable in length so that they
engage with the rear part of the frames of the bicycles as near to the saddles
as possible.
In order that our invention may be fully understood we will more particularly
describe it making reference to the accompanying drawings in which :-
Figures 1 and 2 Sheet No. 1 are views in front and rear elevation respectively
showing the application of our improved attachment.
Figures 3 and 4 Sheet No. 2 are broken views-on an enlarged scale-showing
the clamp sockets at one end of the front cross bar.
Figures 5 and 6 Sheet No. 2 are views-on an enlarged scale of one of the
brackets for connecting the steering coupling rod to the front forks of the bicycle.
Figures 7 and 8 Sheet No 2 are broken views-on an enlarged scale-showing
the clamp at the top end of one of the diagonal back stays, and
Figures 9 and 10 are views-on an enlarged scale of a modification in the
construction of the said diagonal stays.
Throughout the views similar parts are marked with like letters of reference.
Referring to the accompanying drawings A designates the front main cross bar
which is provided with a clamp socket such as a at each end by which it is attached
to the steering sockets or heads of the bicycles as shown by Figure 1 Sheet No. 1.
In order to provide for the varying rake of the steering heads of bicycles the
one clamp a is made axially adjustable with respect to the bar A by means of a
clamp socket such as a' as shown by Figures 3 and 4 Sheet No. 2.
B, B, designate the arms and C the coupling rod for connecting the forks or
frames carrying the two steering wheels to ensure their synchronous movement.
The arms B are each provided with a clamp socket such as by which they are
fixed to the opposite and adjacent prongs of the forks carrying the steering wheel
as shown by Figure 1 Sheet No. 1. The rod C is made adjustable in its length in any
convenient manner but preferably by means of a right and left handed screw D as
shown. As an alternative arrangement the rod C may be provided with clamp
sockets at its ends adapted to be fixed to the rods operating the front wheel brakes.
E designates the rear main cross bar which has snugs e at each end by which it
is fixed to the opposite and adjacent ends of the axles of the driving wheels by the
usual nuts thereon as shown by Figure 2 Sheet No. 1. This cross bar is made
adjustable in length either in the manner shown or by any other suitable device.
This cross bar carries snugs e, e', to which are attached the diagonal stay rods F, F,
each of which is connected at its upper end to the nearest prong of the upper back
fork carrying the driving wheel as shown by Figure 2 Sheet No. 1 by means of a
clamp socket such as as shown by Figures 7 and 8 Sheet No. 2. In order to
provide for the varying rake of the upper back forks carrying the driving wheels
of bicycles the clamp sockets may be attached to the stay rods F by means of
axial and hinge joints designated by f1 and 2 respectively in Figures 9 and 10
Sheet No. 2. As an alternative construction the stay rods F, F, may be crossed as
shown by dotted lines in Figure 2 Sheet No. 1 in which case the cross bar E is
preferably made of one fixed length and the front cross bar A made adjustable in

page_text: length. The stay rods F, F, may also be made adjustable in length so as to be
capable of being attached to the upper back fork as near to the saddle as possible.
We are aware that cross bars and links have already been used to couple two
bicycles together side by side and we do not therefore claim such broadly, but
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:―
1. The herein before described combination of parts forming an improved
attachment for connecting two bicycles together.
2. In a device for connecting two bicycles together to form one velocipede for
two riders, the use of diagonal stays such as F, F, to truss and stay the frames
together, as set forth.
3. An attachment for coupling two safety bicycles together consisting essentially
of the front main cross bar A, of the rear main cross bar E, of the steering
coupling bar C and of the diagonal stay rods F, F, all combined, arranged and
adapted to operate, as and for the purpose set forth.
