PROVISIONAL SPECIFICATION.
Improvements in Brakes for Bicycles and similar Vehicles.
I, ELZA DELZERN HINKLEY, residing at No. 136, Spring Street, Sing Sing, in
the County of Westchester, and State of New York, United States of America,
Telegraph Operator, do hereby declare the nature of this invention to be as
follows:
This invention relates to brakes for bicycles and similar vehicles, and the
object thereof is to provide an improved device of this class which is simple
in construction and operation, and which may be attached to or connected with
bicycles or similar vehicles as usually constructed.
The hub or axle of the drive wheel of the vehicle is provided at its opposite
ends with the usual flanges or rims with which the spokes are connected, and in
the practice of my invention I secure to one end of said hub or axle a brake hub
which consists of two separate parts, one of which is placed on each side of one
of said flanges or rims, and said parts are bolted together, and the outer part
is much thicker than the inner part.
I also secure to one of the lower horizontal rods of the frame of the vehiole
in front of the axle or shaft of the drive wheel, a backwardly directed arm or
bar, said arm or bar being secured to said rod of the frame by clamps or in
any desired manner, and I also provide two semi-circular brake shoes which are
hinged to said arm or bar, and which are adapted to enclose said brake hub,
and the outer end of the lower brake show is provided with a link, and binged
to the upper side of the upper brake shoe is a lever the rear end of which is
curved downwardly, and connected with said link, and the forward end of said
lever extends forwardly in the direction of the pedal shaft, and is. provided with a
cross head or arm by means of which said lever may be depressed by the foot of
the rider.
Connected with the lower part of said lever forwardly of its connection with the
upper brake shoe is an expansive spring which is designed to normally hold the
forward end of said lever in a raised position, and when the lever is in this
position, the brake shoes will be separated from the brake hub, and all that is
necessary in order to apply the brake shoes is to depress the forward end of said
lover, and the lower end of said spring preferably connected with the bar or
arn with which said brake shoes are connected.
The brake shoes are each preferably formed of two parts bolted together, and
the bearing surfaces thereof, are covered with leather, rubber or similar material,
and my improved brake is simple in construction and operation, and well adapted
to accomplish the result for which it is intended.

AI, ELZA DELZERN HINKLEY, residing at 136, Spring Street, of Sing Sing,
County of Westchester, State of New York, United States of America, Telegraph
Operator, 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 brakes for bicycles and similar vehicles, and the.
object thereof is to provide an improved device of this class which is simple
in construction and operation, and which may be attached to bicycles or similar
vehicles as usually constructed,
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms' a part, in which the separate parts of my improve-
ment are designated by the same numerals of reference in each of the views; and
in which:
Fig. 1, is a sectional side view of, that part of the bicycle or similar vehicle
in which the drive wheel is mounted;
Fig. 2, a partial section on the line 2, 2, of Fig. 1, and,
Fig. 3, a plan view of the construction shown in Fig. 1,
In the drawing forming part of this specification,, I have shown at 5, one side
of the fork of a bicycle or similar vehicle, which extends from the support of the
axle of the drive wheel upwardly and forwardly to the seat support, and_at_G,
one of the horizontal bottom rods of the, frame, and I have also shown at 7, the
shaft or axle of the drive wheel, and at 8, a number of the spokes thereof, and in
the practice of my invention I provide a brake of the following construction.
The hub or axle 7, of the drive wheel is provided at each side with the usual
annular flanges 9, with which the spokes 8, are connected, and mounted on
said axle and enclosing one of said flanges is a brake hub 10, consisting of two
separate annular parts 11; and 12, which are placed on the opposite sides of the
flange or rim 9, and which are connected by screws or bolts 13, which are passed.
therethrough between the spokes 8, and said hub turns with the drive wheel as
will be readily understood.
"
The outer part 11, of the hub is thicker than the inner part, 'and my improved
brake bears on the perimeter thereof, and the separate parts of said hub are
preferably composed of two pieces, the ends of which overlap, so as to more
easily secure the same to the shaft or axle of the drive wheel.
I also secure to one of the bottom rods 6, of the frame, an angular-arm 14, which
is provided with clamps 15, by means of which connection with, the rod 6, is made
and said arm is provided, with a backwardly directed' extension 17, to which is
pivoted two similar semi-circular brake shoes 18, and these brake shoes :18,
enclose the outer portion of the hub 10, and the upper brake shoe is provided with
u, lug 19 in which is pivotally mounted a lever 20, which is provided with a
backwardly and downwardly curved extension, 21, which is pivotally connected
with a link 22, which is pivotally connected with the outer end of the lower brake
shoe. 18, at 23, and the lever 20, projects forwardly and is provided with a
transverse arm.24, which extends transversely of the frame of the bicycle, as shown
in Figure 3 and said lever is connected with the backwardly directed extension 17,
of the arm 14, by an expansive spring 26.
The brake shoes 18, are each composed of two separate parts 26, and 27, which
are connected by pins or bolts 28, and the inner sides thereof are provided with
bearings, 29, composed of rubber,, leather or any suitable material, and these

page_text: bearings are provided centrally with outwardly directed flanges 33, which fit
between the separate parts 26, and 27, and which are held in position by the
pins or bolts 28, and the operation will be readily understood from the foregoing
description when taken in connection with the accompanying drawing, and the
following statement thereof.
In the normal position of the parts of the brake shoes 18, are held out of
contact with the brake hub 10, by the spring 25, and the arm 24, of the lever 20,
may be easily reached by the foot of the rider, and whenever it is necessary to
apply the brake, the lever 20, is depressed, and this operation forces the brake
shoes 18 into contact with the hub 10, as will be readily understood, and when
pressure on the lever 20, is removed, the spring 25, will operate to remove the
brake shoes from the perimeter of the brake hub.
My improved brake is simple in construction and operation, and perfectly
adapted to accomplish the result for which it is intended, and it will be apparent
that changes in, and modifications of the construction described, may be made
without departing from the spirit of my invention, or sacrificing its advantages.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I déclare that what
I claim is:-
1. A bicycle or similar vehicle provided with a brake which consists of a brake
hub mounted on the hub or axle of the drive wheel, an arm connected with one
side of the frame, two circular brake shoes pivotally connected with said arm and
enclosing said hub, and a lever pivotally connected with the upper brake shoe
and with a link which is pivotally connected with the outer end of the lower brake
shoe, said lever being directed forwardly, substantially as shown and described.
2. A bicycle or similar vehicle provided with a brake which consists of a brake
hub mounted on the hub or axle of the drive wheel, an arm connected with one
side of the frame, two circular brake shoes pivotally connected with said arm and
enclosing said hub, and a lever pivotally connected with the upper brake shoe
and with a link which is pivotally connected with the outer end of the lower
brake shoe, said lever being directed forwardly and means for holding the brake
shoes out of contact with the hub, substantially as shown and described.
3. A bicycle or similar vehicle provided with a brake which consists of a brako
hub mounted on the hub or axle of the drive wheel, an arm connected with one
sido of the frame, two circular brake shoes pivotally connected with said arm
and enclosing said hub, and a lever pivotally connected with the upper brake
shoe and with a link which is pivotally connected with the outer end of the
lower brake shoe, said lever being directed forwardly, and being provided with
an expansive spring whereby it is held in a raised position, substantially as shown
and described.
4. The combination with a bicycle of a detachable brake hub, comprising two
disks 11 and 12, each of which is provided with a central opening, through which
the barrel of the wheel is adapted to pass, one of said disks being mounted on
each side of the annular flange to which the spokes are secured, and said disks
being held together by screws 13, substantially as and for the purpose described.
Dated this 18th day of February 1898.
