Improvements in and connected with Velocipedes.
We, EDWARD DAVIES, Engineer and EDWARD JAMES VINCENT DAVIES
Engineer both of Cambridge Cottage, Wood Green, Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention is primarily intended to relate to velocipedes of the class known
as bicycles but certain parts of the invention may be utilised in tricycles and other
forms of velocipedes.
The invention relates (1) to a new arrangement for holding the handle; (2) a
new arrangement for actuating brake; (3) a new arrangement for locking the
steering post or automatic steering; (4) a new arrangement of spring bearings for
the wheels; (5) a new form of double wheels with but two hubs; (6) a new mode
of attaching the spur wheels for the chain; (7) and a new mode for attaching
pedal arms to the pedal shaft.
According to the first and second parts, we make the present handle stem
moveable in the steering post and held up at a certain position by a suitable
spring. On the bottom of this moveable bar, we attach the shoe of the brake
for the wheel; consequently on pressing down this moveable bar the brake is
applied to the periphery of the front wheel. On the front of the steering post
near the top we form a stud or projection which may be attached by means of
a collar. To the top of the brake bar we pivot a short link and arrange the
free end for the usual handle. From the free end of the link is a pendant length
of arm which passes through the stud or projection of the front of steering
post and is secured by nuts so that to put on the brake it is only necessary to
depress the ends of the handle. According to the 3rd part we arrange on the
upper part of frame a sliding carrier having a projecting point or bolt to pass
into another projecting part fixed to a collar on the steering post, this carrier
can be moved back or forward by a suitable handle. According to the 4th part
instead of the usual fork for the bearing of the axle of the wheels we form the
end of the frame with a wider fork or other form and let into the same a sliding
box carrying a moveable part held up at a certain distance by springs. This
moveable part carries the bearing for the axle of the wheels. The box is retained
in fork or other form by guides into which enter the point of set screws and is
moved and held longitudinally by a set screw or screws so as to enable the chain
to be tightened up. According to the 5th part we arrange the driving wheel
with two felloes each of which have a separate set of spokes. This wheel is
practically a divided wheel with but two hubs. The spokes are so arranged as
to admit of a spur wheel for the chains to be placed between the felloes so that
the wheel can be driven from the centre. According to the 6th part the ends
of the frame which support the spur wheel is forked eo that the spur wheel may
be placed between the forks which enables the spur wheel axle to be better held
than in the present form. According to the 7th part in place of the usual nuts
or pins for attaching the pedal arms of the pedal shaft we screw the shaft with
a right and left handed screw thread, and screw thread the eye' in arm so that
in working there will be a tendency for the arms to screw up tighter.

Improvements in and connected with Velocipedes.
We EDWARD DAVIES and EDWARD JAMES VINCENT DAVIES both of
Cambridge Cottage Wood Green Middlesex Engineers 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 is primarily intended to relate to velocipedes of the class known
as bicycles, but certain parts of the invention may be utilized in tricycles and other
forms of velocipedes.
The invention relates (1) to a new arrangement for actuating the brake, by a
new arrangement for holding the handle, (2) a new form of double wheel with but
one hub.
According to the first part we make the handle movable on the steering post
and held at the necessary horizontal position by a spring. Depressing the handle
presses down a part passing through the steering post and puts on the brake.
To enable our invention to be properly understood, we will describe the same
with aid of the accompanying drawings.
Figure 1 is a side elevation according to this invention.
Figure 2 a partial plan on line a, Y, Figure 1.
Figure 3 detached view drawn to a large scale, of the manner of securing steering
handle and of actuation the brake.
Figure 4 front view of top of preceding figure.
Fi
igure 5 detached view of holder part for handle bar.
Figure 6 detached partial view of hind double wheel, and part of frame.
Figure 7 plan of Figure 6.
Figure 8 details of construction of double wheels.
A, is the steering post, made of metal tubing, in the top of which is a bush
part B secured by a collar nut C; clamped round the top of B is a part D,
which is secured by the screw E; the outside of D, has a vertical eye F for a
rod G which is secured at any desired height by the set screw G. To the top of
this rod G is secured a T shaped sleeve H through which the handle bar J passes;
this sleeve has an opening Hin centre for an arm K secured on the handle bar .J
by a set screw K' which acts as a stud to prevent the handle rising up beyond the
horizontal position. The free end of this arm K is attached to a pendant rod L
passing through a collar L¹ and secured by set screw L' this collar is attached to
the upper part of a tube L³ passing through steering post A and having the brake
spoon M attached on bottom, so that by pressing down the handle as shown by
dotted lines puts on the brake. The spring L keeps the brake normally off the
tyre of wheel.
.
The double wheel is made upon a single hub so that the two wheels have
only the same bearing as one wheel, but enables the driving chain wheel to be
central.
This mode of construction is illustrated at Figure 8.
To better attach the pedal shaft and chain wheel upon same, we make the frame
forked as at O and secure the standards P which carry the bearings for shaft N,
on each side of frame O, so that the pedal shaft is very firmly supported at
each end.
t
The standards P may be either pendant from the frame as in Figures 1 and 2;
or rest upon the tops as a Figures 6 and 7.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
1. The manner of connecting the handle that admits of it being depressed; and

page_text: attaching to it the rod L passing through steering post A and having brake
spoon M at bottom the handle being held at the horizontal position by spring L as
herein before described and illustrated by the accompanying drawings.
2. The method of constructing a double wheel on one hub with naves for the
spokes attached as described and illustrated by the accompanying drawings.
