Improvements in Brakes for Railway and other Cars or Carriages.
I, THEODOR SUCHLAND of 2 Anhalt Strasse, in the City of Berlin in the Kingdom of
Prussia, and German Empire, Gentleman, do hereby declare the nature of my
Invention for "IMPROVEMENTS IN BRAKES FOR RAILWAY AND OTHER CARS OR
CARRIAGES to be as follows:-
32
My invention relates to improvements in brakes for railway and other cars or
carriages.
In order to effectually brake railway and other ears with rapidity in case of danger
I employ a wedge brake either alone or in combination with the customary brake. If
my said improved brake is employed alone it is arranged to operate gradually or if
desired with great energy and almost instantaneously; if the same is employed in con-
junction with the ordinary brake mechanism as danger brake only, it is arranged to
act instantaneously and will bring the car or carriage to which it is attached in the
shortest possible space of time to a standstill.
As a matter of course the brake is arranged to act on the car or carriage irrespective
of the direction in which the same is driven.
The brake is arranged at the one end of the car and in order to avoid having to turn
the brake handle to the right when driving in the one and to the left when driving in
the other direction I employ two spindles which carry two suitable pinions, which
latter are in gear with the double toothing of a suitable rod or rail.
This said rack runs along the entire length of the car or carriage and is carried at
each end and if necessary at any suitable intermediary part in suitable bearings. The
rod is provided with the two formed standards or double brackets which are each
slotted and in which said slots two pins or bolts affixed to a longitudinal rod are
guided so that the said rod can glide beneath the two standards.
Two suitable brackets are fixed to the aforesaid longitudinal rod in such manner
that the springs on the rods or spindles which have their bearings at the one end in
the brackets and at the other end in the standards or double brackets will press at the
one end against one of the last mentioned brackets and at the other end against the
standard or double bracket.

their ends two suitable brake blocks.
At the foward end of the rod is a frame or sliding guide in which the sliding rod is
guided to the ends of which two slides are attached which glide in two
standards and carry the 8 brake wedges which are located above the car wheels.

The vertical side of the rectangular slides is provided with curved slots in which
the pivots so gear that by the longitudinal movement of the slides the brake blocks are
pressed against the wheels. Suitable springs are arranged beneath the slides and
press continuously against the same so as to hold the said slides constantly in their
highest position when the rods will lay in the lowest point where the two converging
inclines of the slide meet.
The operation of my improved brake is as follows:-
The crank handle which can be readily applied or removed is placed on the right
hand spindle and in braking is turned to the right so that the toothing of the rod and
the entire rod is moved in the direction in which the carriage is driven and the spring
compressed whereby the rod or its standards or double brackets will in consequence of
the slots in the same and the guide pins glide on the longitudinal rod which is drawn
forwards by the spring so that the brake blocks are brought in contact with the wheels
and a gradual braking operation attained.
If however it is desired to effect a rapid braking the crank is rotated further so that
the brake blocks are pressed onto the wheels, will be automatically drawn faster and an
almost instantaneous stoppage of the car or carriage achieved.
In moving the wedges towards the wheels the connecting rod glides in a suitable
frame. If the crank is now given free the brake wedges will retire from the wheels
and the slide will be returned to its original position.
If the car or carriage is running in an opposite direction the crank is applied to
the spindle in consequence of which the brake blocks and brake wedges come into
action.
In order to retain the brakes in braking position the spindles can be provided with
a suitable ratchet wheel and pawl and instead of making the crank movable a suitable
bent crank can be so applied to each spindle that the operation of the one is not hindered
by the other.

page_text: I THEODOR SUCHLAND of 2 Anhalt Strasse, in the City of Berlin, in the Kingdom
of Prussia, and German Empire, Gentleman, do hereby declare the nature of my
Invention for IMPROVEMENTS IN BRAKES FOR RAILWAY AND OTHER CARS OR CARRIAGES,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to improvements in brakes for railway and other cars or
carriages.
If
In order to effectually brake railway and other cars with rapidity in case of danger
I employ a wedge brake either alone or in combination with the customary brake.
my said improved brake is employed alone it is arranged to operate gradually or if
desired with great energy and almost instantaneously; if the same is employed in
conjunction with the ordinary brake mechanism as danger brake only, it is arranged
to act instantaneously and will bring the car or carriage to which it is attached in the
shortest possible space of time to a standstill.
As a matter of course the brake is arranged to act on the car or carriage irrespective
of the direction in which the same is driven.
Fig. 1, is a longitudinal section of the lower part of a tramway car with my
improved brake mechanism. Fig. 2, is a side view of the same with the brake
applied. Fig. 3, is a top view and Fig. 4, a cross section.
The brake is arranged at the one end of the car and in order to avoid having to turn,
the brake handle to the right when driving in the one and to the left when driving in
the other direction, I employ two spindles a, and b, which carry the pinions c, d,
which latter are in gear with the double toothing of the rod or rail, e.
This said rack or rod e, runs along the entire length of the car or carriage and is
carried at each end and if necessary at any suitable intermediary part in appropriate
bearings.
The rod is provided with two U-formed standards or double brackets f, g, which are
each slotted at h, i, and in which said two slots the pins or bolts k, l, affixed to the longi-
tudinal rod m, are guided so that the said rod can glide beneath the two standards f, g.
Two brackets n, o, are fixed to the longitudinal rod m, in such manner that the
springs, y, on the rods or spindles r, s, which have their bearings at the one end in
the brackets n, o; and at the other end in the standards or double brackets f, g, will
press at the one end against the bracket n or o and at the other end against the standard
or double bracket for y. At about the centre of the length of the rod m, I attach two
bearings m, n, and at the ends of the same like bearings t, u, in which the cross
rods, w, o, p', are arranged which latter carry at their ends the brake
blocks, y
At the forward end of the rod e, is a frame or sliding guidez, in which the sliding
rod a', is guided, to the ends of which the two slides & are attached which glide in
the two U shaped standards and carry the eight brake wedges c, d, which
;

page_text: are located above the wheels, e', f.
The vertical side of the rectangular slides, ¹ is
provided with curved slots g', in which the pivots so gear that by the longitudinal
movement of the slides the brake blocks are pressed against the wheels. Springs are
arranged beneath the slides and press continuously against the same so as to hold the
said slides constantly in their highest position when the rods will lay in the lowest
point of the same where the two converging inclines of the slide meet.
The operation of my improved brake is as follows, whereby it is supposed that the
car is being driven in the direction as represented by the arrows.
The crank handle which can be readily applied or removed is placed on the right
hand spindle b, and in braking is turned to the right so that the toothing of the rod e,
and thus the entire rod is moved in the direction of the arrow and the spring 4, com-
pressed whereby the rod e, or its standards or double brackets,,, will in consequence
of the slots in the same and the guide pins k, l, glide on the longitudinal rod, m,
which is drawn forward by the spring 9, so that the brake blocks, are brought in
contact with the wheels and a gradual braking operation attained.
If however it is desired to effect a rapid braking, the crank is rotated further so
that the brake blocks c¹ are pressed onto the wheels, will be automatically drawn
faster and an almost instantaneous stoppage of the car or carriage obtained.
In moving the wedges towards the wheels the connecting rod a¹ glides in the
frame z.
If the crank is now given free the brake wedges will retire from the
wheels and the slide 6 will be returned to its original position as shown in Fig. 1,
by means of the springs . If the car or carriage is running in an opposite direction
the crank is applied to the spindle a, in consequence of which the brake blocks y,
and brake wedges come into action. In order to retain the brakes in braking
position the spindles a, and b, can be provided with a suitable ratchet wheel and pawl
and instead of making the crank removable a suitably bent crank can be so applied
to each of the spindles a, b, that the operation of the one is not hindered by the other.
Having now particularly described and ascertained the nature of my said invention
and the manner in which the same is to be performed I declare that what I claim is:
A brake for railway and other cars or carriages characterised by the construction,
arrangement and employment of the rod e, (provided at its one or at both ends with
toothing on one or both sides) and the pinions c, d, spindles a, b, and crank k³, so, ilat
by rotating the pinion c, or d and spindle a, or by means of the crank the longi-
tudinal rod m, which is guided in the standards or double brackets f, g, by means of
the pins or bolts k, l, is moved forwards and the brake blocks a or y pressed onto the
wheels by means of the springs p, q, whilst the cross bar or rod a', which is guided in
the frame z, is also carried forward by the rode, and slide and also the brake
wedges c¹ or d¹, by means of the pins or bolts ', so that the said wedges are pressed
onto the wheels whereby the slide b', will be returned to its highest position by the
springs, as soon as the wedges are released; or any mere combination or modifica-
tion of the parts of my said brake substantially as set forth in the foregoing
* specification and represented in the accompanying drawings.
