I, HENRY LOUIS FRED TREBERT, of 372, South Salina Street, in the City of
Syracuse, and State of New York, United States of America, Mechanic, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in brakes for vehicles, and particularly
velocipedes, and has for its object the production of a brake for the desired
purpose, which is especially simple in construction, and highly efficient in use:
and, to this end, the invention consists in the combination, construction and
arrangement of the component parts of a vehicle-brake.
This brake is designed to lock a driving member to a driven part with a
minimum strain upon the bearings of said driven part, to permit rotation of the
driven part without effecting rotation of the driving member, and to retard
rotation of the driven part. It is obvious, however, that the brake need not be
used for all of said purposes unless required.
Said brake consists essentially of a driven part, friction-pieces secured to the
driven part, a stationary parf, a driving member, engaging pieces secured to
the driving member, and clutch-members between the driven part and the
driving member and between one of the engaging pieces secured to the driving
member and the stationary part.
The driven part is usually the hub of a driving wheel of a vehicle, or a sleeve
adapted to be fixed to said hub. The periphery of the driven part is generally
formed with ratchet-shaped teeth or projections having their front faces sub-
stantially radial and their outer faces inclined inwardly and rearwardly.
The friction-pieces secured to the driven part preferably consist of rings or
sleeves which may be fixed to the driven part, one in advance of the other, in
any desirable manner, as by threads, and are usually arranged at opposite sides
of the ratchet-shaped teeth or projections of the driven part and provided upon
their inner faces with suitable frictional engaging surfaces, as fibre-rings.
The stationary part generally consists of a sleeve which is interposed between
said friction-pieces, encircles the same axis as the driven part, and is suitably
secured, as by a projecting arm, to the frame for the driven part or to any other
desirable support.
The driving member usually consists of a sprocket or other driving wheel
encircling the portion of the driven part provided with the aforesaid ratchet-
shaped teeth or projections. The periphery of the driving member is suitably
formed for engaging power-transmitting means, as a sprocket-chain, and the
inner face of said member is generally formed with an annular groove.
The engaging pieces secured to the driving member are preferably fixed to
opposite side faces thereof, one of said engaging pieces being movable into
engagement with the adjacent friction-piece secured to the drifen part, and the
opposite engaging piece being formed with ratchet-shaped teeth or projections
having their front faces formed substantially flat and their outer faces inclined
rearwardly toward the former engaging piece.

page_text: The clutch-members between the driven pait and the driving member consist
of balls or rollers which are arranged in the groove in the inner face of the
driving member and are moved forwardly as said driving member is moved in
the same direction. As said clutch-members move forwardly, they roll on the
inclined outer faces of the ratchet-shaped teeth or projections of the driven part
and are forced outwardly, thus locking the driving member to said driven part.
It will be understood, however, that said clutch-members are released as soon
as the driving member is moved backwardly slightly, and that the driven part is
then free to revolve without effecting revolution of the driving member. Said
clutch-members are generally held apart the desired distance and caused to
move simultaneously by a suitable separator, as a perforated ring formed angular
in cross-section. This separator may be returned to its normal position by a
spring, although said spring may be dispensed with, if desired.
The clutch-members between one of the engaging pieces secured to the driving
member and the stationary engaging part consist of balls or rollers which are
moved rearwardly as the driving member is moved in the same direction. As
the clutch-members move rearwardly, they roll on the inclined outer faces of the
ratchet-shaped teeth or projections of said engaging piece and force the driving
member and the stationary part laterally in opposite directions against the
adjacent friction pieces for retarding the rotation of the driven part. The latter
clutch-members are also preferably held apart and caused to move simultane-
ously by a suitable separator, as a perforated ring.

Improvements in Vehicle-brakes.
I, HENRY LOUIS FRED TREBERT, of No. 872, South Salina Street, in the City of
Syracuse, County of Onondaga, and State of New York, United States of
America, Mechanie, 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 improvements in brakes for vehicles and particularly
velocipedes, and has for its object the production of a brake for the desired pur-
pose, which is especially simple in construction and highly efficient in use:
and to this end the invention consists in the combination, construction and
arrangement of the component parts of a vehicle-brake.
Referring to the drawings, Figure 1 is an elevation, partly in section, of
my vehicle-brake, adjacent parts of the vehicle-frame being indicated by dotted
lines.
Figures 2 and 3 are vertical sectional views taken, respectively, on lines 2- 2
and 3-3, Figure 1.
Figure is a sectional view taken on line 4-4, Figure 2, the chain shown in
the preceding figure being omitted.
Figures 5, 6 and 7 are isometric views, respectively, of the stationary part,
one of the engaging pieces of the driven part, and one of the rings connecting
the clutch-members.
This brake is designed to lock a driving member to a driven part with a

page_text: minimum strain upon the bearings of said driven part to permit rotation of the
driven part without effecting rotation of the driving member and to retard
rotation of the driven part. It is obvious, however, that the brake need not be
used for all of said purposes unless required. Said brake consists, essentially,
of a driven part A, friction-pieces a secured to the driven part A, a
stationary part B, a driving member (', engaging pieces secured to the
driving member, and clutch-members D E between the driven part and the
driving member and between one of the engaging pieces secured to the driving
member and the stationary part.
The driven part A is usually the hub of a driving wheel of a vehicle, or a sleeve
adapted to be fixed to said hub. The periphery of the driven member is generally
formed with ratchet-shaped teeth or projections 2 having their front faces sub-
stantially radial and their outer faces inclined inwardly and rearwardly.
The friction-pieces a secured to the driven part A preferably consist of
rings or sleeves which may be fixed to the driven part oue in advance of the
other in any desirable manner, as by threads, and are usually arranged at
opposite sides of the ratchet-shaped teeth or projections a² of the driven part A,
and provided upon their inner faces with suitable frictional engaging surfaces,
as fibre-rings ³.
The stationary part B generally consists of a sleeve which is interposed between
said friction-pieces aa, encircles the same axis as the driven part A and is
suitably secured as by a projecting arm b to the frame for the driven part, or to
any other desirable support.
The driving member usually consists of a sprocket or other driving wheel
encircling the portion of the driven part A provided with the aforesaid ratchet-
shaped teeth or projections a². The periphery of the driving member is suit-
ably formed for engaging a power-transmitting means, as a sprocket-chain
and the inner face of said member is generally formed with an annular groove
The engaging pieces secured to the driving member Care preferably
fixed to opposite side faces thereof, one of said engaging pieces being movable
into engagement with the adjacent friction-piece a secured to the driven part A,
and the opposite engaging piece being formed with ratchet-shaped teeth or pro-
jections having their front faces formed substantially flat, and their outer
faces inclined rearwardly toward the former engaging piece.
The clutch-members between the driven part and the driving member
consist of balls or rollers which are arranged in the groove in the inner face
of the driving member C and are moved forwardly as said driving member is
moved in the same direction. As said clutch-members move forwardly they
roll on the inclined outer faces of the ratchet-shaped teeth or projections of
the driven part A and are forced outwardly, thus locking the driving member
to said driven part. It will be understood, however, that said clutch-members
are released as soon as the driving member is moved backwardly slightly, and
that the driven part is then free to revolve without effecting revolution of the
driving member. Said clutch-members D are generally held apart the desired
distance and caused to move simultaneously by a suitable separator, as perforated
ring formed angular in cross-section. This separator may be returned to its
normal position by a spring, although said spring may be dispensed with, if
desired.
The clutch-members E between one of the engaging pieces secured to the
driving member and the stationary part B consist of balls or rollers which are
moved rearwardly as the driving member is moved in the same direction.
As the clutch-members E move rearwardly, they roll on the inclined outer
faces of the ratchet-shaped teeth or projections of said engaging piece, and
force the driving member (and the stationary part 1 laterally in opposite
directions against adjacent friction-pieces aa for retarding the rotation of the
driven part, thus transmitting substantially equal pressure to the driven part
in opposite directions substantially lengthwise of its axis.

page_text: The latter clutch-members E are also preferably held apart and caused to move
simultaneously by a suitable separator, as a perforated ring e.
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
