Complete Specification Left, 29th Apr., 1892-Accepted, 11th June, 1892.
PROVISIONAL SPECIFICATION.
Improvements in and relating to Velocipedes.
We JOHN GODDARD of Beeston, in the County of Notts, Foreman of Messrs.
Humber & Co. Ltd., Cycle Manufacturers and MARTIN DIEDERICH RUCKER of
32 Holborn Viaduct in the City and County of London, Manager, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to an improved brake, and it consists of a pair of arms
adapted to operate on a drum on the axle of the wheel or wheels in a similar manner
to a band brake, the object being to obtain a simple and efficient brake of the band
type, which is not liable to drag on, or cause friction when the brake is off.
To attain this end we take two curved rigid arms; each lined with leather and
shaped to fit the drum on the axle. These arms are pivotted at one end either
directly or indirectly to the fork or frame of the cycle, and in close proximity to
one another. The length of one arm is such that it encircles about one third the
circumference of the drum, and the length of the other arm such that it encircles
about five eighths thereof. The free ends of these arms are connected by a link
carrying an arm at right angles thereto. The end of this arm is connected to the
operating hand lever by a rod or bar in the usual manner.
When the hand lever is operated to apply the brake,, the link connecting the
two curved brake arms, is canted, drawing each arm into contact with the drum on
the axle.
Dated this 1st day of August 1891.

COMPLETE SPECIFICATION.
Improvements in and relating to Velocipedes.
We JOHN GODDARD of Beeston, in the County of Notts, Foreman, of Messrs.
Humber & Co. Ltd. Cycle Manufacturers, and MARTIN DIEDERICH RUCKER of
32 Holborn Viaduct, in the City and County of London, Manager, 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 brake and it consists of a pair of arms
adapted to operate on a drum on the axle of the wheel or wheels in a similar
manner to a band brake, the object being to obtain a simple and efficient brake
of the band type which is not liable to drag on, or cause friction when the
brake is off.
To attain this end we take two curved rigid arms, each lined with leather and
shaped to fit the drum on the axle. These arms are pivotted at one end either
directly or indirectly to the fork or frame of the cycle, and in close proximity to
one another. The length of the arm is such that it encircles about one third the
circumference of the drum, and the length of the other arm is such that it encircles
about five eighths thereof. The free ends of these arms are connected by a link
carrying an arm at right angles thereto. The end of this arm is connected to the
operating hand lever by a rod or bar in the usual manner.
When the hand lever is operated to apply the brake, the link connecting the
two curved brake arms is canted, drawing each arm into contact with the drum on
the axle.

page_text: In order that our invention may be more fully understood we will more par-
ticularly describe it making reference to the accompanying drawing in which
Figure 1. is a broken view inside elevation showing our improved brake_as_
applied to the steering wheel of a cycle.
Figure 3. is a broken view-partly in section-showing the method of fulcrating
the brake arms to the frame of the machine and
Figure 2. is a broken view-partly in section-of the link and arm connecting
the brake arms.
Throughout these parts similar parts are marked with like letters of reference.
On to the hub of the wheel or on to the axle thereof is formed or fixed a brake
drum A of the usual type. On to the fork or frame ✗ of the machine are
fulcrated two rigid arms B and B¹, each curved to the radius of the brake drum
and preferably lined or faced with leather. The lengths of these brake arms are
such that their free ends come to a point approximately under the centre of the
brake drum. The free ends of these arms B and B¹, are connected together by a
link C carrying an arm C¹ approximately at right angles thereto. The end of the
arm C₁ is connected to the operating hand lever by a suitable rod or link D. When
this rod or link D is pulled upwards the link C is canted thereby drawing the two
brake arms B and B₁, into contact with the brake drum A. When the rod or
link D resumes its normal position the brake arms B and B', come clear
away from the drum so that there is no friction or tendency to drag on when the
brake is off.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction hereinbefore described and illustrated by the accom-
panying drawing, but that we hold ourselves at liberty to make such changes and
alterations as fairly fall within the spirit and scope of our invention.
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.
The improved construction of brake for velocipedes, as hereinbefore described and
illustrated by the accompanying drawing.
