PROVISIONAL SPECIFICATION.
Improvements in and relating to Velocipedes.
I CHRISTOPHER SHACKLOCK of 24 Chapel Street, Beeston, in the County of
Notts, Foreman Fitter, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved construction of band brake for velocipedes
and it has for its objects, the prevention of frictional contact of the band with the
drum when not in use, and the simple adjustment of the connections enabling the
band to be applied with the least possible movement of the operating lever.
I attain these ends by constructing a band brake in the following manner :-
1 take a metal band lined with leather or similar material and of a length nearly equal
to the length of the circumference of the drum to which it is to be applied. To one
end of this band I pivotally attach a short link, to the centre of which is hinged an
arm terminating in a screw adapted to thread into a screwed socket fulcrated on a
bracket fixed to the other end of the band. This screw attachment enables the
internal size of the band to be varied. The free end of the link carrying the con-
necting arm is connected through a suitable rod or link to the operating lever in
the well-known manner.
To prevent the band from coming into contact with the drum when it is
inoperative, which it is likely to do merely from its inability to support its own
weight, it is connected by a flexible connection to an arm fulcrated to any con-
venient part of the frame of the machine, this connection being made in such a
position that while it allows the band to fit tightly on the drum under the influence
of the operating mechanism, it ensures the band coming away clear of the drum
when the brake is off.

COMPLETE SPECIFICATION.
Improvements in and relating to Velocipedes.
I CHRISTOPHER SHACKLOCK, of 24 Chapel Street, Beeston, in the County of
Notts, Foreman Fitter, 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 :-
My invention relates to an improved construction of strap or band brake for
velocipedes, and it has for its objects the prevention of frictional contact of the
strap or band with the drum when not in use, and the simple adjustment of the con-
nections, enabling the strap or band to be applied with the least possible movement
of the operating lever.
I attain this end in the manner illustrated by the accompanying drawing, in
which
Figure 1 is a view in side elevation of my improved brake.
Figure 2 is a view in front elevation thereof with the coupling and operating
links removed, and
Figure 3 is a view in front elevation of the adjustable coupling link.
Throughout these views similar parts are marked with like letters of reference.

page_text: The metal strap or band A has a lining A of leather or similar material, and it
is of such a length that its ends overlap when encircling the drum X. Near to
one end of this strap or band is fixed a bracket B to which is pivotted a short
link C, to the centre of which is hinged an arm D terminating in a screw threaded
into a socket D' fulcrated to a bracket B' fixed near to the other end of the strap
or band A. This arm D and socket D' form an adjustable coupling link enabling
the internal diameter of the strap or band A to be varied. The free end of the
link C carrying the arm D of the adjustable coupling is connected by means of a
suitable rod E to the operating lever on the handle bar in the well-known manner.
The strap or band A is prevented from coming into contact with the drum X
when the brake is "off"-which it may do merely from its inability to support its
own weight by a spring F fixed to a bracket G mounted on a pin H carried by a
bracket H fixed to any convenient part of the fork or frame of the machine, the
said spring being connected to the strap or band A in such a position that while it
allows the said strap or band to fit tightly on to the drum under the influence of
the operating mechanism, it ensures it coming away clear of the drum when the
operating mechanism is released to take the brake "off." The bracket G is locked
to the pin H by means of a dowel pin h when the correct position of the spring F
has been determined. The overlapping ends of the strap or band A are provided
with a slot a and a pin a¹ respectively, to keep the said ends engaged with one
another.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereinbefore described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
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. The improved brake for velocipedes, as hereinbefore described and illustrated
by the accompanying drawing.
2. In a strap and drum brake for velocipedes, the use of a spring support to
prevent the strap or band from coming into contact with the drum when the brake
is "off," as set forth.
3. In a strap and drum brake, the combination of the strap or band A, of the
link C fulcrated at or near to one end of the said strap or band, of the adjustable
link D, D', fulcrated at or near to the other end of the strap or band, of the
operating rod or lever E fulcrated to the free end of the link C, of the spring F
fixed at one end to the strap or band A and adjustably attached at the other end
to the frame or fork of the machine, all combined, arranged, and operating as and
for the purpose set forth.
