PROVISIONAL SPECIFICATION.
An Improved Detachable Brake Lever Clip or Fulcrum.
I, CHARLES THOMAS BROCK SANGSTER, Works Manager to the Cycle Components
Manufacturing Company Limited, of Bournbrook, near the City of Birmingham, do
hereby declare the nature of this invention to be as follows: —
This invention relates to a detachable brake lever clip or brake lever fulcrum and
has for one of its objects, a simple and efficient detachable bracket, and for another
object, to dispose the axis or centre upon which the lever turns upon the side of,
and in the horizontal plane of the axial line of, the handle bar which the said clip
or bracket embraces.
The said clip consists of a vertically disposed band clip somewhat of a ☐ figure
or resembling a stirrup in shape, with the flat side presented outwards, and with
the terminal ends, which preferably come underneath the bar, made into short
gapped or bifurcated sleeves or knuckles enclosing swivelling bushes or joints,
which are respectively formed with a transverse plain and screwed hole where-
through a laterally directed and headed screw pin passes, and by the screwing up
of which the band clip is drawn in and contracted around a handle bar or part of a
machine to which it is to be connected.
The inwardly presented side of the flat part of the band clip, which has a hole
through its middle, is fitted with a solid bearing block or concaved seating with the
inner face curved to a radius about equal to that of the handle bar and against
which the convex outside of the said bar takes a seating, whilst directed outwardly
from the middle of the solid bearing block, and passing through the hole in flat side
of the band is a fulcrum pin or neck upon which the brake lever turns as a centre
and terminating the said fulcrum is a screw pin with a flat upon one side for taking
a D-pierced washer coming up to a shoulder formed at the junction of the neck with
a screw pin receiving the nut that keeps the handle bar in place on the fulcrum.
The top and bottom edges of the bearing block are flattened or facetted to fit
within corresponding flats of the band at the junction of the curved part with the
flat side, so as to form an additional security for preventing the seating from
rotating when in position.
I wish it to be understood that I do not confine myself to the particular shape of
band clip, or to the method of contracting the same around a handle bar, neither to
the shape of the bearing block and its position relative to the band, as these details
may be varied without departing from the nature of my invention.

I, CHARLES THOMAS BROCK SANGSTER, Works Manager to the Cycle Components
Manufacturing Company Limited, of Bournbrook, near the City of Birmingham,
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 detachable brake lever clips, or brake lever fulcrum
brackets and has for one of its principal objects, a simple and efficient detachable
bracket, so constructed as to carry the axis or centre upon which the lever turns
upon the front side of, and in the same horizontal plane as the axial line of the.
handle bar which the said clip or bracket embraces.
Figure 1 of the accompanying drawing represents a front elevation of a part of
a cycle handle bar and brake work, with the fulcrum pin or pivot of the brake
lever connected to the handle bar by one form of detachablo bracket clip
constructed according to one form of my invention.
Figure 2 is an underside plan of a part of Figure 1.
Figure 3 is a section of Figure 2 upon the dotted line x, but with the brake
lever removed, whilst
Figure 4 is a section upon the dotted line a¹, Figure 2, the lever being also not
shown in this view.
Figure 5 represents the band clip and its drawing up screw separately.
Figure 6 represents separate views of the fulcrum pin, with its washer and nut.
The same letters of reference indicate corresponding parts in Figures 1 to 6 of
the drawings.
This said form of brake lever attachment bracket consists of a vertically disposed
band clip a, somewhat of a D figure or resembling a stirrup in shape, with a flat
side a¹, presented outwards, so as to come on the front side of the handle bar b,
and with the terminal ends a², which preferably come underneath the said bar,
made into short gapped or bifurcated sleeves or knuckles a³, enclosing swivelling
bushes or joints a, which are respectively formed with a plain and a screwed
transverse hole a, a", wherethrough a laterally directed and headed screw pin c,
passes, and by the screwing up of which the band clip is drawn in and contracted
around the handle bar or part of a machine to which it is connected.
The inwardly presented side of the flat part of the band clip, which has a
hole a, through its middle, is fitted with a loose bearing block d, with the inner
face provided with a concaved seating d¹, curved to a radius about equal to that of
the handle bar and against which the convex outside of the said bar takes a seating,
whilst directed outwardly from the middle of the said block, and passing through
the hole in flat side of the band is a fulcrum pin or neck d², upon which the brake
lever e, turns as a centre the said fulcrum pin being terminated by a screw end d³,
with a flat d, upon one side for taking a D-pierced non-rotating washer f, coming
up to a shoulder formed at the junction of the neck with a screw pin receiving the
nut g. The said washer and nut keep the brake lever in place on the fulcrum yet
admits of the same freely turning thereon. The top and bottom edges of the
bearing block are flattened or facetted at d, to fit within corresponding flats a, of
the band at the junction of the curved part with the flat side, so as to form an
additional security for preventing the seating from rotating when in position.
Figure 7 represcuts an elevation of a modified form of brake lever fulcrum bracket
constructed according to my invention.
Figure 8 is a transverse vertical section of Figure 7 upon the dotted line x²,

page_text: Figure 9 represents a separate view of the bearing block, partly in section and
partly in elevation.
Figure 10 represents the combined fulcrum and drawing-up pin separately.
a is the band clip, the free ends a', of which are drawn together by a cross
pin c, upon which is threaded a concaved faced bearing block d, with the concaved
face d', presented innermost and forming a seating for the handle bar b. The said
block is partially split at d³, to admit of the same gripping the handle bar on the
screwing up of the nut e, on the screwed end c', of the pin c, which has an enlarge-
nent or collar d², at the other end on which the brake lover turns as a fulcrum.
The bearing block has collars do, surrounding the ends of the hole through which
the cross pin is passed and extending into the holes, in the ends of the clip,
whilst the fulcrum pin is prevented from rotating by the inner end g¹, of the brake-
lever spring g, lying in a gap g, crossing one side of the block and coming upon a
flat c, formed on the top of the said pin and being on the same level as the bottom
of the gap g.
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 :-
First In a detachable cycle brake lever clip, the combination with a band
clip encircling or embracing the handle bar or like part of a machine, with a loose
and seated bearing block, carrying the fulcrum or pin whereon the brake lever
turns, so that on the tightening up of the said clip by a screw pin, nut or equivalent,
the said bearing block is closed against the handle bar in common with the band,
substantially as described and set forth.
Secondly-A detachable cycle brake lever clip, comprising a band clip
encircling or embracing a handle bar or other member, and provided with a
drawing-up screw or equivalent, and a loose seated bearing block located between
the clip and the member embraced thereby, and having an integrally formed
fulcrum or neck, substantially as and for the purpose described and set forth in
Figures 1 to 6.
Thirdly :- A detachable cycle brake lever clip or fulcrum, comprising a band
clip embracing the handle bar or member carrying the brake lever, a drawing up
screw, and a loose seated or concave faced bearing block, located between the
handle bar and the inside of the said clip, and having integrally formed with it a
fulcrum piu or neck, having a flatted screw end adapted to receive a D-pierced
washer and a nut, substantially as and for the purpose described and set forth in
Figures 1 to 6.
Dated this 19th day of February 1898.
