I, PHILIP CASEY, Junior, of 210, Atlantic Street, in the City of Paterson, County
of Passaic, and State of New Jersey, U.S.A., Gentleman, do hereby declare the nature
of this invention to be as follows:-
--
This invention relates to improvements in brakes for street and railway cars and the
like, and its object is to provide such vehicles with a brake for quickly and readily
stopping the same in cases of emergency; of simple, strong and durable construc-
tion, reliable in operation and easily and quickly handled.
The invention consists in the improved emergency brake for street-and railway
cars and the like, and in the combination and arrangements of the various parts
thereof, substantially as will be hereinafter more fully described.
Referring to the accompanying drawing, in which like letters of reference indicate
corresponding parts in each of the several figs.: Fig. 1, is a side elevation-partly
in section of a car truck provided with my improved brake; Fig. 2, a detail top plan
view of a certain brake controlling ring and of the plate or frame supporting
the same, and Fig. 3, a detail view of a certain forked lever and the rod operated
thereby.
The truck consists of the platform a and the trames b, which latter form the bear-
ings for the axles c and d, on which are mounted the car wheels e and f-other parts,
like shoe-brakes, springs, etc. are not shown in the drawings, as the same are not
necessary and do not form a part of my invention.
On the inner axle d of the truck is mounted a disk g provided in its periphery with
a series of radially arranged sockets h adapted to be engaged by a locking bolt i,
downwardly projecting from the block k, which latter is slidingly arranged in the
rectangular frame or box m, suspended by means of braces from the platform of
the truck, to which latter it may also be secured by bolts or in any other desired
manner. To the top of said block is secured a rope or chain p', passing over pulleys p
and p2, and penetrating the platform a of said car and also a recessed plate a¹,
embedded in and secured to said platform.
To the free end of said chain or rope is secured a ring p³, adapted to fit and rest in
the recessed portion of said plate a¹, and which ring is used for the purpose of lift-
ing the block k and the bolt i out of engagement with the socketed wheel or disk g.
The block k is provided on its front portion with a socket k², adapted to be engaged
by the rounded end of the horizontally arranged stem or rod n, which latter is
slidingly mounted in the rectangular frame or box m and also in the cap n² of the
cylindrical chamber n³, which latter projects horizontally from the said rectangular
frame or box m.
Within said receptacle or cylindrical chamber n³ is arranged a spiral spring n³, sur-
rounding the said stem or rod n and bearing with one end against the cap n², and
with its other end against a collar nt, secured on the said stein.
An additional collar n¹ is arranged on the stem n and is adapted to bear. against
the outer portion of the cap n², to thus limit the rearward movement of said stem.

page_text: At or near the front portion of the stem n is arranged an annular groove no engaged
by the forked portion o of a hand lever o¹, which latter penetrates the platform a and
is pivotally secured thereto as at o².
The forward upper portion of the block k is inclined as at k¹, for the purpose of
facilitating the forward pushing or moving of the rod n by means of the said block k,
when the latter is lifted
up.
In operation, when it is necessary to stop the vehicle, to prevent collisions or
accidents, the hand lever o¹ is swung backwards on its fulcrum, thereby withdrawing
the stem or rod n from the socket 2, of the block k and allowing the latter by its
own weight to drop down upon the periphery of the disk or wheel g, and the moment,
one of its sockets h is in alignment with the bolt i, the latter will drop into said
socket and thus prevent further rotation of the axle d, as will be manifest.
After the vehicle has been stopped the block k is again returned to its normal posi-
tion by pulling the chain or rope puntil the rounded end of the stem n again
engages the socket k², and thus locks the said block k and bolt i.

Improvements in Emergency Brakes for Street and Railway Cars.
I, PHILIP CASEY, Jr., of 210, Atlantic Street, in the City of Paterson, County
of Passaic, and State of New Jersey, U.S.A., Gentleman, 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 street and railway cars and
the like, and its object is to provide such vehicles with a brake for quickly and
readily stopping the same in cases of emergency; of simple, strong and durable
construction, reliable in operation and easily and quickly handled.
The invention consists in the improved emergency brake for street and railway
cars and the like, and in the combination and arrangements of the various parts
thereof, substantially as will be hereinafter more fully described and finally embodied
in the clauses of the claims.
Referring to the drawings filed with the Provisional Specification, in which like
letters of reference indicate corresponding parts in each of the several figs.: Fig. 1
is a side elevation-partly in section of a car truck provided with my improved
brake; Fig. 2 a detail top plan view of a certain brake controlling ring and of the
plate or frame supporting the same, and Fig. 3 a detail view of a certain forked lever
and the rod operated thereby.
The truck consists of the platform a and the frame b, which latter forms the
bearings for the axles c and d, on which are mounted the car wheels e and f―other
parts, like shoe-brakes, springs etc., are. not shown in the drawings, as the same are
not necessary and do not form a part of my invention.
On the inner axle d of the truck is mounted a disk g. provided in its periphery
with a series of radially arranged sockets h. adapted to be engaged by a locking
bolt i, downwardly projecting from block k, which latter is slidingly arranged in the
rectangular frame or box m, suspended by means of braces m¹ from the platform of
the truck, to which latter it may also be secured by bolts or in any other desired
manner.
.

page_text: To the top of said block is secured a rope or chain p', passing over pulleys p
and p2 and penetrating the platform a of said car and also a recessed plate a¹
embedded in and secured to said platform.
To the free end of said chain or rope is secured a ring p³, adapted to fit and rest
in the recessed portion of said plate a', and which ring is used for the purpose of
lifting the block k and the bolt i out of engagement with the socketed wheel or
disk g.
The block k is provided on its front portion with a socket k², adapted to be
engaged by the rounded end of the horizontally arranged steam or rod n, which
latter is slidingly mounted in the rectangular frame or box m and also in the cap n²
of the cylindrical chamber m³, which latter projects horizontally from the said
rectangular frame or box m.
Within said receptacle or cylindrical chamber n³ is arranged a spiral spring n³,
surrounding the said stem or rod n and bearing with one end against the cap n², and
with its other end against a collar n*, secured on the said stem.
An additional collar n¹ is arranged on the stem n and is adapted to bear against
the outer portion of the cap n², to thus limit the rearward movement of said stem.
At or near the front portion of the stem n is arranged an annular groove n
engaged by the forked portion o of a hand lever o¹, which latter penetrates the
platform a and is pivotally secured thereto as at o²..
The forward upper portion of the block k is inclined as at k¹, for the purpose of
facilitating the forward pushing or moving of the rod n by means of the said block k,
when the latter is lifted up.
In operation, when it is necessary to stop the vehicle, to prevent collisions or
accidents, the hand lever o¹ is swung backwards on its fulcrum, thereby withdrawing
the stem or rod n from the socket 2, of the block k and allowing the latter by its
own weight to drop down upon the periphery of the disk or wheel g, and the moment,
one of its sockets h is in alignment with the bolt i, the latter will drop into said
socket and thus prevent further rotation of the axle d, as will be manifest.
After the vehicle has been stopped the block is again returned to its normal
position by pulling the chain or rope p-until the rounded end of the stem n again
engages the socket k², and thus locks the said block k and bolt í.
I do not intend to limit myself to the precise construction as shown and described
as various alterations can be made without changing the scope of my invention, but:
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:
1 The combination with the truck of a vehicle and the axles of its wheels, of a
disk mounted on one of said axles and provided in its periphery with a series of
radially arranged sockets, a block slidingly supported from the platform and provided
in one of its sides with a socket or recess, a bolt projecting from the lower portion of
said block and adapted to engage one of the sockets in said disk, a spring controlled
stem slidingly supported from the platform and adapted to engage the socket in said
block, means such as a chain for returning said block and bolt to normal position,
and means for operating the spring controlled stem or rod to withdraw the same
from the socket or recess in the block, substantially as and for the purposes described.
2: The combination with a truck of a vehicle and with its axles, of a disk mounted
on one of said axles and provided in its periphery with a series of radially arranged
sockets, a frame supported by said truck, a block slidingly arranged in said frame,
a bolt carried by said block and adapted to engage one of the sockets in said
disk, a spring controlled stem or rod slidingly arranged in said frame and adapted
to lock said block in its normal position, means-such as a chain for lifting said
block into its normal position, and means for operating the spring controlled stem
or rod, substantially as and for the purposes described.
3: The combination with a truck of a vehicle and the axles carried thereby, of
a disk mounted on one of said axles and provided in its outer periphery with a

page_text: series of radially arranged sockets, a frame supported by the truck, a block
slidingly arranged in said frame and carrying a bolt adapted to engage one of
said sockets in the disk, said block being provided with a socket or recess, a
spring controlled stem slidingly arranged in said frame and adapted to engage
the socket in the block, means-such as a chain for returning said block and bolt
to normal position, and means for operating the spring controlled stem, 'or rod;"
substantially as and for the purposes described.
