JOHN BOYD DUNLOP, Ailesbury Road, Dublin, Gentleman, and ARTHUR DREW,
Selly Park, Birmingham, Works Manager, do hereby declare the nature of
this invention to be as follows:-
This invention is to produce a simple brake-lever clip or fulcrum.
We provide a simple clip of the usual form one lug of which is tapped, a
coiled spring with projecting ends, a bolt, and a nut. The bolt is first passed
through the hole in the brake-lever then screwed into the tapped lug of the clip,
then into the coiled spring and through the other lug. The bolt is screwed
sufficiently tight to adjust the brake-lever joint, and the nut on the end of the
bolt locks the clip on the handle bar.
One end of the spring rests on the handlebar and the other supports the brake-
lever.
One bolt only is necessary to adjust the brake-lever, hold the coiled spring in
position, and lock the clip on the handlebar.

Improved Brake-lever Clip for Cycles.
We, JOHN BOYD DUNLOP, of Ailesbury Road, Dublin, Gentleman, and ARTHUR
DREW, of Selly Park, Birmingham, Works 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:-
-
This invention has for its object the production of a simple brake-lever clip in
which one bolt shall serve to carry the brake lever in such a manner that the
joint or bearing can be adjusted, to hold the spring in position, and to lock or
secure the clip on the handlebar.
And in order that the manner in which we attain our object may be properly
understood, we will describe our invention with the aid of the accompanying
drawings, wherein,
Figure I is a front elevation of the clip and adjacent portions of the brake
lever and handlebar.
Figures II & III are sections on the lines II-II and III-III respectively
in Figure I.
Like numerals indicate like parts throughout the drawings.

page_text: The clip 2 itself is of the well known split form. The lugs are bored through,
the hole in the lug 3 being tapped, and the lug 4 having a clearance hole. The
distance between the lugs is made great enough to leave room for the herein-
after described spring 5 when the clip is tightened on the handlebar 6. The
brake lever 7 is adapted to work on the bolt 8, the head of the bolt and the hole
in the lever being preferably of conical formation, as seen best in Figure III.
The bolt has a screw thread corresponding to that in the lug 3.
The spring 5 preferably consists of a double coil of tempered wire; the arm li
supports the short end of the lever while the arm 12 bears against the underside
of the handlebar.
The parts are assembled as follows: The clip 2 is sprung on to the handle-
bar 6 with the tapped lug 3 in front. The bolt 8 is passed up to the head through
the hole in the lever 7 and is then screwed into the lug 3. The spring is now
held with its coils between the lugs 3 & 4, and the bolt is screwed
further in, until the lever is held with sufficient tightness between the head of
the bolt and the face of the lug 3. The bolt now passes through the spring 5
and the lug 4, its end projecting beyond the rear face of the said lug. A nut 12,
preferably backed by a washer 13, is now screwed upon the projecting end of
the bolt so as to contract the clip 2 on the handlebar. Finally, the hooked end
of the spring is sprung into place under the short arm of the lever 7. To adjust
the joint or bearing of the lever, it is only necessary to release the nut 12 and
screw the bolt 8 further or less far, as the case may be, into the lug 3.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is: -
1. A brake lever clip for cycles, constructed, arranged, and adapted to operate
substantially as herein described and illustrated.
2. A brake lever clip for cycles, comprising a single bolt adapted to carry the
brake lever in such a manner that the joint or bearing may be adjusted, to hold
the spring in position, and to lock or secure the clip on the handlebar.
