PROVISIONAL SPECIFICATION.
Improvements in Fluid Pressure Brakes for Velocipedes and like
Machines.
I, JOHN GEORGE AULSEBROOK KITCHEN, of 28 Rose Grove, Ardwick,
Manchester in the County of Lancaster, Mechanician do hereby declare the
nature of this invention to be as follows:-
This invention relates to fluid pressure wheel brakes of velocipedes and similar
machines, in which the pressure is obtained by the hand and consists in further
improvements in the construction of brakes according to that described in the
Specification of Letters Patent No. 16581 A.D. 1893.
The improvements have for their object mainly the variable adjustment of the
brake block and shoe in the direction of the tyre or wheel for the purpose of
obtaining the maximum effect, especially in cases where the brake is to be readily
applied to and detached from the machine.
According to this invention a suitable clip or bracket formed for ready
attachment to the frame of the machine is provided with a slide arranged to
permit of adjustment in the direction of the tyre or wheel and with means for
locking the parts.
In some cases the clip or bracket is provided with a grip formed to fit the
sleeve or tube through which the inflating tube passes, or other suitable projection
formed on the metal or other rigid shell or carrier of the hollow flexible brake
block or cushion, the grip being provided with a screw for tightening its hold.
In other cases the clip or bracket is provided with a slide having flat surfaces,
similar surfaces being formed in connection with the rigid shell. One of the
surfaces is pierced with a slot or holes and the two surfaces are bolted or screwed
together.
The clip or bracket is preferably formed so that it may be reversed or turned
upside down, the grip part or the slide being set to one side, so that according to
the position of the part set off with relation to the wheel the slide itself is further
from or nearer to the wheel, and thereby greater adjustment is obtained.
Dated this 16th day of July 1896.

Improvements in Fluid Pressure Brakes for Velocipedes and like
Machines.
I, JOHN GEORGE AULSEBROOK KITCHEN, of 44 Albert Road Alexandra
Park, late of 28 Rose Grove Ardwick, Manchester in the County of Lancaster,
Mechanician, 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 relates to fluid pressure wheel brakes of velocipedes and similar
machines, in which the pressure is obtained by the hand and consists in further

page_text: improvements in the construction of brakes of the kind described in the
Specification of Letters Patent No. 16581 A.D. 1893.
The improvements have for their subject mainly the variable adjustment of the
brake block and shoe in the direction of the tyre or wheel for the purpose of
obtaining the maximum effect, especially in cases where the brake is to be readily
applied to and detached from the machine.
According to this invention a suitable clip or bracket formed for ready,attach-
ment to the frame of the machine is provided with a slide arranged to permit of
adjustment in the direction of the tyre or wheel and with means for locking the parts.
On the drawing appended hereunto,
Figure 1 shows a side view, Figure 2 a front view and Figure 3 a plan of one..
arrangement of the improved slide and the half of a bracket suitable for
attachment to the fork crown of a bicycle.
Figure 4 a side view and Figure 5 a plan of a clip or bracket. suitable for
attachment to the fork sides of a bicycle.
Figure 6 a side view and Figure 7 a plan of a flat slide and part of the bracket
to which it is fixed.
In the arrangements shown by Figures 1 to 5 the clip or bracket d fixed to. the
frame of the cycle is provided with a grip d formed to fit the sleeve or tube a
through which the tube for inflating the extensible block or cushion e fixed in. the
shoe or carrier 6 of the pneumatic or other fluid pressure brake passes. The grip
consists of a split ring or hoop which can be tightened on the sleeve d by a
screw d. The grip is formed on a bracket d which in Figures 1 to 3 is shown
adapted for being fixed to a round tube by means of another half hoop-not
shewn on the drawing-bolted to the bracket in the well known manner.
Figures 4 and 5 the bracket is shown forked with sides d³ between which and the
plates e the sides of the fork can be clipped. The parts of the bracket for
attaching it to the frame may be formed in any other way suitable for fixing it to
the part of the frame where the brake is to be located.
On
The tube a can be readily raised or lowered so as to bring the block as near to
the tyre as desired, and preferably the part d' gripping the tube a is set down or
not made central with the part d clipping the frame and the bracket arranged so
that it can be reversed or turned upside down, so that by fixing it in the reversed
position on the frame a further variation in the distance from the point of
attachment on the frame to the face of the brake pad can be obtained. By this
arrangement the same fixings are more readily applicable to various kinds of
velocipede frames.
In the arrangement shewn by Figures 6 and 7, the brake shoe or carrier bis
formed at its end with a flat slide, and the end of the bracket with a corre-
sponding flat, face f, one part being. preferably made with a tongue fitting into a
groove in the other part to prevent the carrier b from turning on the bracket.
The slide b' is formed with a slot and fixed to the face f by a screw or bolt h, or
the slot may be formed in the part f; to permit the adjustment of the brake block
in respect of the tyre and the face f is thrown to one side of the bracket d, so that
the reversal of the bracket on the frame permits a further adjustment of the brake
block...
Instead of the tubular slide containing the inflating tube or a flat slide at the
end of the shoe or carrier being arranged for being gripped by or bolted to the
bracket attached to the frame as shewn on the drawings, a round or flat slide may
be formed at any other part of the shoe if more convenient for the special
arrangement of the frame of the velocipede or similar vehicle to which the brake
is to be applied.
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
TUL
..:
use wheel brakes

2. In fluid pressure wheel brakes of the kind described in my Specification
No. 16581 A.D. 1893, the formation of the brake block carrier with a tubular or
flat slide adjustably gripped or bolted by or to the bracket attached to the frame,
substantially as herein before described and illustrated by the drawings and for the
purpose set forth.
