Improvements in Two-side Seated Bicycles.
ALBERT SHELDON WEAVER, of the City of Hamilton, in the County of.
Wentworth, in the Province of Ontario, Dominion of Canada, Piano ¡Manu-
facturer, do hereby declare the nature of this invention to be as follows :-
My improvements relates to an adjustable two-side seated bicycle, and consists
of a frame having two sides, each side provided with an adjustable seat supported
by vertical standards which form a part of said frame, and two ground wheels in
tandem form in front and rear of said seats, also opposite each seat are a pair of
handles connected to meobanism for guiding the front wheel, each pair of handles
being capable of guiding the bicycle independently.
The objects of my improvements are, first, to provide a bicycle which is capable
of seating, side by side, two persons, second, to afford facilities for the proper
adjustment of the seats to suit a heavy and light person, and the guiding of the
machine, and third, to provide means of applying one of the adjustable side seats,
to a middle position located on a line with the two ground wheels, when the side
seats are not used.
The adjustment of the said side seats, to an outward or to an inward position tends
to evenly balance the machine sideways, when one person is of greater or lesser
weight than his or her companion, and the adjustment of the said seats to a
forward or rearward position, is for the purpose of modifying the distance from
seats to pedals, when one person is of longer proportion than his partner.

COMPLETE SPECIFICATION (AMENDED).
Improvements in Two-side Seated Bicycles.
ALBERT SHELDON WEAVER, of the City of Hamilton, in the County of
Wentworth, in the Province of Ontario, Dominion of Canada, Piano 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:-
My improvements relates to an adjustable two side seated bicycle, and consists

page_text: of a frame having two sides, each side provided with an adjustable seat, supported
by vertical standards which form a part of said frame, and two ground wheels in
tandem form in front and rear of said seats, also opposite each seat are a pair of
bandles connected to mechanism for guiding the front wheel, each pair of handles
being capable of guiding the bicycle independently.
The objects of my improvements are, first to provide a bicycle which is capable
of seating, side by side two persons, second, to afford facilities for the proper
adjustment of the seats to suit a heavy and light person, and the guiding of the
machine and, third, to provide means of applying one of the adjustable side seats,
to a middle position located on a line with the two ground wheels, when the side
seats are not used.
I attain these objects by the mechanism illustrated in the accompanying drawing
in which :-
Figure 1, is a side elevation and,
Figure 2, is a plan of a bicycle, these two views embodying my invention.
Figure 3, is a front elevation of the same, the seats rear wheel and driving
mechanism and cross curved brace being left out.
Similar letters and numerals refer to similar parts throughout the several
views.
The two sides of the frame of the bicycle, tubular in section, and form as shown
in Figure 1 of drawing, are indicated by A, and are held in relative position by
means of the front cross braces B, and C, with central front part A', of frame, the
seat braces E, and F, the curved cross brace K which extends from standard to
standard forming a part thereof, and the rear rigid axle H, provided with nuts I,
to secure said axle to frame. The two vertical tube standards A', which form a
part of the frame and to which the upper ends of said braces F are connected are also
strengthened by the braces A³, which extend from the front part of frame to the
lower part of standards A³, and also form a part of the frame. The seat supports J..
have slotted holes 2, for the purpose of attaching and adjusting thereto a seat or
saddle, and are provided with under shanks J', which fit into the said tube standards,
and are capable of vertical adjustment, and are held in the desired position by means
of set screws 3. This horizontal adjustment of said seat supports tends to evenly
balance the machine sideways, when one person is of greater weight, or longer
proportion than his, or her partner. The cross brace K, having two rearward curves,
to allow perfect freedom to the inner limbs of the side cyclists, is a part of, or
attached to the middle, or lower part of the standards, and has a hub, similar to the
upper ends of said standards, to allow one of the said seat supports J, to be inserted
therein, for the purpose of seating one person in the middle of the machine.
It will be perceived, that the brace E, the forward end of which is attached to
the middle of the front part of frame by means of lugs 4, and pin, and the rear end
to the top of central hub of said seat brace K, by detachable pin 5, can by
removing this pin and at the same time one of the supports J, be attached to the
upper end of either one of the two standards, and held in position by inserting
said pin 5, or a support J, or in lien of said pin, three seat supports may be
supplied. The three preparations alluded to, for seat supports, are on the same
circular line from radial centre of lugs 4, in which said brace E, is allowed to
swivel.
M, are the foot pedals, or cranks, either two of which may be reversed, if
desired, in order to allow the inner limbs of the cyclists to operate together in unison,
though when the central seat is used alone the said pedals are in proper position. These
cranks drive the rear ground wheel N, in the ordinary manner of bicycles, by
means of the sprocket wheels O, the chains P, and the sprocket wheels R. These
sprocket wheels R, form a part of the extension hubs S, which revolve on the said
through axle H, each said extension hub has an opening 6, to allow for the
adjustment of ball bearings if used, and if necessary.
The front ground wheel T, is connected to the machine by means of the bent
fork U, in the usual manner, the hollow tube shank, or upper part of this fork is

page_text: round, and hidden from view, commencing from the line 9, immediately above the
fork proper, as seen in Figure 3, of the drawing, this line 9, denotes the lower end
of the central front part A, of the frame A, and the commencement of said shank.
The upper end of this shank is secured to the inner end of the central lever V¹ of
the two levers V, and the inner end of each of the side levers V, is secured to each
of the shanks W₁ of the guiding handles W, said shanks fitting into the side tubes
of upper part of front of frame. These two side levers, when operated by one or
both the said pair of handles W, operate the central lever V1 by means of cross
rod Y, which is connected to the outer ends of the three said levers. Either pair
of handles will suffice to guide the machine, as both pairs are connected to the said
cross rod.
The handles could be so arranged as to be interchangeable, that is, to allow
either pair to be applied to the hollow or tube shank of the fork, this would be
in case one person was on the devised central seat on the brace K.
This interchanging could be accomplished by simply inserting the shank W' of
either of the two handles into the tube or round aperture of shank of fork and
fastened to same by means of set screw or other convenient manner.
In case a lady should occupy the central seat, the brace E, may be removed.
It will be obvious, that by the fact of the interchanging of the seats, as
previously mentioned, and also by the fact of the guiding mechanism being
applicable to either one of the three seats. A cyclist may take a partner to a
distant city, and return alone on the bicycle, this being a very important element
in my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. In a bicycle the combination of a two sided frame held suitably apart by cross
braces and the axle for the rear wheel, and having a tubular standard on each side
capable of supporting and allowing to be adjusted vertically the seat supports J,
having slotted holes 2, and shanks J¹, the braces E and F, and pedals opposite each
seat support to drive the machine, substantially as described and set forth.
2nd. In a bicycle, the combination of the two sided frame, having a tubular
standard on each side to receive the shanks of the seat supports J, said supports
being capable of vertical adjustment, the curved cross brace K, having a centrally
located bub adapted to receive the shank J', of the seat support J, to adjust the same,
and the braces E, and F, and the pedals in line with the centre of the said side seat
supports to drive the machine, substantially as described and set forth.
3rd. The combination of the two sided frame, with through rigid axle, provided
with wheel N, having central hub, and extension hubs S, with openings 6, the chain
wheels R, forming a part of said hubs S, the said extension hubs driven independently
from each of the side frames by separate driving mechanism, substantially as described
and set forth.
4th. The combination of the two sided frame A, provided with front tubular
part A', secured together by cross braces B and C, the two pairs of handles W,
having shanks W₁, adapted to work in the upper front tubular part of said frame
the levers V, and V', secured to said shanks W', and to the cross rod Y, for
guiding front ground wheel T, and the adjustable brace E, substantially as
described and set forth.
