Improvements in Brakes for use on Wheels.
I, EDWARD WARWICK, of Alma Street, Aston, in the County of Warwick
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:-
This invention consists of the combination of parts hereinafter described forming
and constituting a brake specially suitable for use in connection with cycle wheels
and also suitable for use in connection with the wheels of other vehicles.
In the construction of my invention I provide a piece of metallic brake-tube of
any suitable length in accordance with the diameter of tyre used in connection with
my improved brake; the piece of metallic brake-tube is either produced with a
periphical opening or I provide a piece of perfect tube and afterwards form the
side opening therein by means of revolving cutters or other suitable tools; in either
case a concave opening is produced of suitable dimensions to clear the tyre as
hereinafter more fully described.
I next force outwards the material constituting the periphical surface of the
unpierced part of tube, thus forming a cup, or a recess, or a boss, projecting
outwards from the tube.
I next provide a piece of rubber by preference, or in lieu thereof any other
suitable springing yielding material and force such rubber or other material within
the brake-tube.
It will be apparent that the rubber or other suitable material will be gripped
within the two ends of the brake-tube and within the internal periphery of the
unpierced portion of brake-tube and that such rubber or other yielding material
would be exposed through the opening or slot cut or provided in the periphery of
tube.
The ends of the brake-tube and the rubber therein may be cut off in an angular,
round, or other suitable and convenient shape, I next attach a rod or tube to the
cupped or flanged part.
In using my invention I connect the rod or tube in any convenient manner to a
cycle or other vehicle in such a position that the rubber or other yielding surface
provided in the brake-tube would form a brake and take contact against the wheel
tyre of cycle or other vehicle.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is constructed and used, similar letters refer to
similar parts throughout the several views.

Fig. 2. represents a longitudinal section of Fig. 1. with the rubber removed.
Fig. 3. represents the improved brake and brake-rod connected to the cycle-
framing over cycle-wheel.
Fig. 4. represents end view of Fig. 1.
Fig. 5. represents the brake-rubber in detail.
Fig. 6. represents a front view of Figure 3.
Fig. 7. represents a transverse section of Figure 1. on the line A. B.
In carrying out my invention I provide the brake-tube a such tube a can be cut
from a stock length or can be produced as a separate article, out of flat metal,
pierced, folded, and afterwards braized or otherwise jointed. When cut from a stock
length of tubing the opening & is cut away by means of revolving cutters or such
like suitable tools.
I next pierce the brake-tube and force outwards the periphical surface of the

page_text: I next provide the yielding brake part d which consists of a piece of rubber,
by preference, although I claim the use of any other equivalent yielding material,
the brake-part would be placed or forced within the brake tube a the brake part d
is clipped and held between the ends fand between the internal periphery of the
two walls g and h of the unpierced portion of the brake-tube the working portion
of brake part is exposed as shewn at Figures 1 and 6; the ends of brake
tube may be cut off in a rounded form as shown at Figure 2 and the rubber can in
a like manner be cut to match as shewn at Figures 1 and 5 or the ends can be
formed to any other convenient shape, the rubber d being flush with the ends of
the tube a or projecting beyond such tube.
In using my invention I connect the brake-rod k or a brake-rod of any other
suitable shape to the cup c by screwing, compressing, soldering or other suitable
means and then connect the brake rod to cycle-framing e in the manner shewn at
Figure 3 or in any other suitable manner so long as the brake part d is adjusted
over the wheel tyre in a suitable position to take contact with the wheel tyre; the
pressure of the brake part d on the tyre m as shewn at Figure 6 fully illustrates
the action of my improved brake; the pressure of a rubber brake against a
rubber tyre being of such a character as to produce a friction that will stop the
wheel tyre from revolving and at the same time such friction is not calculated to
destroy the cycle wheel tyre.
In a like manner I use other springing material equivalent to rubber as a brake,
either against the hollow tyres or against the solid tyres of cycle wheels, perambu-
lator wheels, carriage wheels dumb-waiter wheels, gun carriage wheels, or the
wheels of any other vehicle.
Having now particularly described and ascertained the nature of my said
invention, and the manner in which the same is to be performed, I declare that
what I claim is :—
1st. The invention as illustrated and described for the purpose described.
2nd. The making of a brake for use against the tyres of wheels by the
combination of rubber, gripped within a tube, in the manner illustrated and
described.
3rd. The making of a brake for use against the tyres of wheels by the
combination of a yielding material equivalent to rubber such yielding material
being gripped within a tube in the manner illustrated and described.
Dated this 23rd day of August 1893.
