I JOSEPH SANDERS of 7 Vicar Street Kidderminster in the County of Worcester
Manufacturer do hereby declare the nature of this invention to be as follows:-
My invention has for its object Improvements in cycle brakes by which I
obviate the objection of the brake acting upon the tread of the tyre and by causing
my brake to bear on the rim of the wheel or sides of the tyre, I can obtain
a substantial clutch or brake power which is equal to any requirement to be met
with and which does not wear the tyre. My brake is simple in construction &
can be readily applied to existing Machines.
In carrying my invention into effect the clutch part of my brake if formed of
two levers pivoted near the centre the lower ends being turned inwards are pro-
vided with rollers cushions or other means for being pressed against the rim of
the wheel or sides of the tyre. The top of the levers are connected to the brake
rod by suitable links so that upon the application of the brake the lower ends
of the levers are closed against the underside of the rim or side of the tyre. The
brake is attached to the machine at or near the pivot of the levers and the brake
handle so arranged on the top so that upon the application of the power the rod
is raised, thus closing the lower, ends against the rim of the wheel or the brake
handle may be attached underneath as at present and a crank arranged at any
convenient point to cause the brake rod to be raised by the upward action of the
pivoted handle. Any suitable spring may be provided if required to retain the
brake in a normal position.

I JOSEPH SANDERS of 7 Vicar Street Kidderminster in the County of Worcester
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:-

page_text: obviate the action of the brake on the wearing or tread surface of the tyre and
at the same time gain increased leverage with less operating power.
My brake is much lighter than others of equal power inasmuch as the various
connections being in tension instead of compression, less metal is rendered
necessary in the various parts while it is simple in action and can be readily
applied to any existing machine..
In order that it may be clearly. understood and more easily carried into practice
I have illustrated the brake as applied to the front wheel and handle of an
ordinary safety and from which. its application to other parts of the machine
can readily be seen.
Figure 1 is a broken off view of the handle head and fork of an ordinary safety
shewing my brake attached thereto.
Figure: 2 is a plan of the handle portion of Figure 1.
Figure 3 is a side elevation of the brake and head portion of Figure 1.
In carrying my invention into effect the clutch part of my brake is formed of
two levers A and A' which are pivoted on one centre at a. The lower ends of
the levers are provided with rollers cushions or other means as shewn by a³ and a³
which are pressed against the side of the tyre T or against the rim S as seen.
by the extentions shewn by dotted lines at a and a. The top of the levers A
and A are connected together by the links K and K' which are contained within
the lever arms A and A¹ thus keeping the whole arrangement in compact form.
The brake rod D is connected at d to the lower ends of the links K and K¹ the
brake being applied by the operation of the rod D in the direction of the arrows X
to effect which the brake handle B is cranked and pivoted at to the clip K
which is fixed on the handle har J as shown by plan at Figure 2. By this
means the pressing of the brake handle B in the direction of the arrow Y operates
the horizontal rod. E in the direction of the arrows Z and this motion is con-
nected to the vertical rod D by the crank C or its equivalent which is attached
to the handle bar stem by the clip M. It will thus be seen that both the vertical
rod D and horizontal rod E are in tension and consequently are of sufficient
strength if formed of wire of reasonable diameter. The brake is retained open
by the spring P' the arms and 22 of which keep the arms of the levers closed
and through them the whole of the other parts in their normal positions as shewn.
The adjustment in the length of the vertical rod D is provided for by the tube d
which is split at to form an attachment to the links K and at d for the rod D
to be inserted. The interior of the tube being tapped with a very fine thread
and the rod provided with a similar thread so that the screw clip de loose the
rod D can be slid in or out of the tube and then fixed in the required position by
the tightening of the clip . As less adjustment is required in the case of the
horizontal rod E the length of tube el is provided having the tapped nose e which
is screwed on to the screwed end of the rod E, the adjustment being effected by
the turning of the tube e¹ for which purpose the hexagonal part or its equivalent
is provided. For the adjustment of the brake with regard to the tyre I mount
the pivot a on the collar N slightly out of the centre of the collar at n so that
the brake may be fixed higher or lower by the reversal of the collar which is
usually sufficient adjustment at this point. It will readily be understood that
I can vary many of the details and shapes of the adjustable and other parts without
departing from my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1st. Improvements in Brakes substantially,as and for the purpose herein set
forth and shewn upon the accompanying drawings.
2nd. A brake consisting of the pivoted levers A and A' in combination with
links K and K folded within the said arms A and A' substantially as and for
the purpose herein set forth.

page_text: 3rd. The combination of the pivoted lever A and A' links K and K¹ handle B
and rods E and D by which the whole of the connections are tensional substan-
tially as herein set forth and shewn.
