An Drake for
Year: 1898

page_text: WILLIAM DAVIS, Totteridge Road, Enfield Wash, Middlesex, Engineer, do
hereby declare the nature of this invention to be as follows;-
-
The improvement consists in a clip round rim of wheel with rolers bearing on
back of rim of wheel. The rolers run perpendicularly on back of wheel, and have
a direct pull on it. I also claim the bell crank lever and attachment for working
brake on after wheel, which is all attached to the fixed frame of cycle. The brake
applyed to the forward wheel would be the same as it is at present, with the
exception of being lifted instead of being pressed down.
The frame of brake is what is caled the horse shoe shape, and passes over the
rim of wheel. It has two rubber (or other material) rolers on the lower end
which fit both sides and back of rim, and when puled up to the rim acts as a
brake (the rolers revolving and the rub and ware on tire of wheel avoided) and
stops the wheel dead. To apply the break to the front wheel the rod from the
lever on handle bar is screwed into end of frame of brake and to apply it the
rolers are puled up against the back of rim. I apply two links from back of fork
connected to frame of brake to take the drag.
To apply the brake to the after wheel of machine I put a clip round the fixed
frame just under the handle bar. The clip carries carries a spindle behind the frame for
a lever to work on. The end of which lever carries a quadrent round the upright
frame to the other end of spindle where it forms a lever to connect to a bell crank
under the bottom frame, which is connected to another bell crank under inner end
of lower after fork. The lever which is connected to the brake passes up between ends
of lower fork, or may be carried up by a rod to work brake on top fork. On the
under side of horse shoe frame of brake I put two pieces of rubber to keep the
frame of brake from rubbing varnish off the fork on which it slides. This arrange-
ment would be princialy for ladies machines.

An improved Drake for by vies and
I, WILLIAM DAVIS, of Totteridge Road, Enfield Wash, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
[Price 8d.1

page_text: formed to be particularly described and ascertained in and by the following state-
ment:-
:-
This invention relates to an improved brake for cycles and other vehicles and
consists of a frame of horse-shoe shape carrying two small rollers which are caused
to bear against each side of the rim of wheel upon being drawn upwards against
the force of a spring. The said frame rests upon the back fork of the cycle, its
two arms extending down on each side of the tyre, and being guided by a rod
passing through a hole in a plate fixed to the fork. A spiral spring encircles
the said rod and tends to keep the rollers on the frame out of contact with the
rim. A band, chain, wire or cord is connected to the rod and passes over a
pulley fixed to the fork and underneath another pulley carried by a bracket
clipped to the frame of the machine just above the crank axle bearing.
The band or chain then passes up and around a third pulley fixed to the diagonal
tube of frame and is connected to one arm of a lever pivoted to a collar clamped
to the frame underneath the handle-bars. The other arm of this lever is forked
and carries a quadrant in front of the frame, and a rod, passing through a tubular
guide fixed to the lamp bracket, is connected to the brake lever and bears upon
the said quadrant so as to raise the other end of the lever when the brake lever is
operated.
By this means the band or chain is pulled so as to bring the rollers on the
sliding frame into contact with the wheel rim and thus to apply the brake.
And in order to clearly understand my invention reference is had to the accom-
panying sheet of drawings in which Fig. 1 is a side elevation of a portion of a
bicycle frame with the brake mechanism attached. Fig. 2 is an elevation of the
horse-shoe shaped frame carrying the brake-rollers, and Fig. 3 is a side or edge
view thereof. Fig. 4 is a plan of the forked actuating lever, and Fig. 5 is a side
view thereof. Fig. 6 and 7 are two views of the guide pulley fixed to the back
fork.
a is the frame of the machine and 6 is the steel band, chain or cord for actuat-
ing the brake. c is the frame carrying the rollers d at the lower end of each arm
as shewn in Figs. 2 and 3. The said arms are provided with a pad or strip of
india-rubber c¹ which bears against the rear fork and prevents wearing away of
the enamel during the sliding motion of the said frame.
To the top of this frame is fixed a rod e passing through a hole
in the guide plate e¹ clamped to the rear fork and encircled by a spiral
spring fitted between the plate and the frame C. To the top of
this rod is attached one end of the band 6 which passes over the guide
pully clamped to the upper end of the frame a below the saddle. The band then
passes down and underneath the guide pulley 9, carried by the bracket g¹ clamped
to the frame above the crank axle bearing, and from thence passes upwards to the
guide pulley and lever i to which it is secured by the adjustable connection k.
The lever i is pivoted to the collar clamped to the head of the machine and is
forked, as shewn in Fig. 4, and formed with a quadrant-shaped front portion ¹.
A rod m, passing through a guide tube m¹ fixed to the lamp bracket, is con-
nected to the ordinary brake lever at its upper end.
In order to apply the brake the said lever is operated so as to force the rod down
upon the quadrant ¹ thus causing the other arm of the lever i to rise and draw
up the band b.
The pulling action on the band raises the brake frame c and brings the rollers d
into contact with the rim n of the wheel, and these rollers revolving on their axes
prevent undue friction and creates a gradual pressure on the rim.
The brake is taken off again by the spring e² forcing down the frame c upon the
pull on the band being released.
The brake mechanism is carried by the fixed framing of the machine with the
exception of the rod m attached to the steering rod o, the said rod m travelling in
the hollowed out portion of the quadrant when steering without actuating the

page_text: lever . As seen in Figs. 6 and 7 the guide pulley f is carried by a bracket f¹
fixed to a clamp f, and one side of the said bracket is cut away at f3 to form an
opening whereby the band may be placed in position upon or removed from the
pulley f.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
(1) The improved brake for cycles and other vehicles comprising a frame carry-
ing two rollers, one on each side of the wheel rim, and a band, chain or cord
running over guide pullies and connected to the said frame and to a lever operated
by the brake lever, for causing the said rollers to be drawn against the wheel
rim, the rollers being forced out of contact with the rim by means of a spring
when the brake is released, substantially as described.
(2) In a brake for cycles and other vehicles the combination of a frame carrying
rollers on each side of the wheel and fitted with a spring, a band, chain or cord
connected to the said frame and to a forked lever formed with a quadrant, a rod
connected to the brake lever and acting upon the said quadrant to operate the
brake, and pullies for guiding the band, chain, or cord from the roller frame to
the quadrant lever substantially as described.
.
(3) The improved brake for cycles and other vehicles substantially as described
and shewn in the drawings.
