Year: 1896

Complete Specification Left, 14th Jan., 1897-Accepted, 27th Mar., 1897
1, CHARLES ROBERT HUTCHINGS, of Grosvenor Chambers, Bournemouth, in the
County of Hants, Solicitor, do hereby declare the nature of this invention to be
as follows:-
The bands or straps usually used for controlling the drums of band brakes, in the
case of cycles, or other vehicles, or light machinery, are generally composed of a
flexible strip or band of steel, faced with leather, and it is found, especially in the
case of cycles, that the heat generated by friction, quickly destroys the leather
facing.
The object of my present invention is to provide a facing for the metal band or
strip of a more durable or heat resisting nature; and, for this purpose, I face or
enclose the metal band or strip with, or in, a covering or facing, preferably composed
of a core of rubber, metal, or other suitable material, and covered or faced, in its
turn, by or with asbestos tápe, millboard, or felt.
The band brake, as above described will also be found particularly applicable to
autocars or horseless vehicles.

Improvements in Band Brakes.
I, CHARLES ROBERT HUTCHINGS, of Grosvenor Chambers, Bournemouth, in the
County of Hants, Solicitor, 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 :-
The bands or strips generally used for controlling the drums of band brakes, in
the case of cycles, or other vehicles, or light machinery, are generally composed of
a flexible strip or band of steel, faced with leather, and it is found, especially in the
case of cycles, that the heat generated by friction, quickly destroys the leather
facing.
The object of my present invention is to provide a facing for the metal band or
strip which will bite and yet be of a more durable or heat resisting nature; and I
find from experiment that asbestos, in the woven tape form, answers the purpose
admirably.
I therefore take a strip of asbestos tape, and secure it upon the inner or concave
surface of the usual metal band by means of rivets or in any other desired and
convenient manner, and the ends may or may not be secured or protected within the
overlapping extremities of said metal band.

page_text: On the accompanying sheet of drawings Figure 1 shows part of a brake band
made in accordance with my invention, and Figure 2 is a section on line A B.
Referring to these drawings, a is the flexible steel or metal band, 6 the lining or
facing of asbestos, and c the rivets by which the latter is held firmly on to the
band.
Instead of using asbestos tape by itself as a facing or lining, I may compose the
latter of a core or backing of thin metal, rubber, or other suitable material,
covered or faced in its turn by or with asbestos tape, and then apply it in this form
to the usual steel or metal, suitable holes for rivets or the necessary provision for
any other convenient form of attachment, being provided.
The hand brake as above described will be found equally useful for auto-cars or
self-propelled vehicles.
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 :-
1. A band brake composed of a flexible strip of metal having a facing or lining
of asbestos substantially in the manner and for particular object hereinbefore
-described.
2. In flexible band brakes, the application of a friction lining of woven asbestos
or asbestos tape, either by itself or combined with a core or backing of thin metal,
rubber, or other strengthening material, substantially as described.
3. The improvement in band brakes for the purpose of reducing the heat
generated by friction and thus producing a brake of a more durable nature,
substantially as herein before described.
Dated this 14th day of January 1897.
