page_text: LETTERS PATENT to Julius Kuntze, of 21, Graskeller, Hamburg, Manufacturer,
for the Invention of "IMPROVEMENTS IN BRAKES"
Sealed the 2nd March 1877, and dated the 6th September 1876.

"IMPROVEMENTS IN
This Invention relates to improvements in brakes for railway vehicles. By
means of this brake, which is continuous and also single working, all brakes of a
tiain can be brought into action at the same time from any of the waggons or fiom
the locomotive, the construction allowing each brake to be operated itself from the
corresponding compartment in which the brakeman is seated
The action of the brake begins when a weight is lowered, in consequence of which
a lever lifts a connecting rod which causes the brake blocks to work against the
wheels of the waggon.
The lowering of the weight is effected by the guard turning a handle fastened to
a shaft, the latter being connected with a lever which has at its under part a
projection, upon which rests a roller of a connecting rod fastened to a weight which
is kept raised during the time when the brake is out of contact By turning the
shaft the lever disengages the weight, which drops and brings the brakes into
operation The rod moves in guides fastened to the front of the waggon, and is
connected with a loop of the weight by means of rollers.
To lift the weight and to bring the brake out of action the lever is lifted by the
guard by means of a chain, the lever is turned which causes the projection of the
lever to be placed under the roller and so to lift the weight.
For disengaging all brakes of a train at the same time a cord is fitted and carried
along the tops of all waggons. Each lever of the brake apparatus is connected
to the cord or cords, so that by pulling the cord from any of the waggons or from
the locomotive all brakes are released and brought into action at one time.
Instead of disengaging the brakes by levers, winding or screwing up apparatus
may be used

BRAKES."
"IMPROVEMENTS IN
This Invention relates to improvements in brakes, especially to the mechanism
by which any number or the whole of the wheels of a train can be operated upon
to bring the train to a standstill By means of this brake, which is continuous and
also single working, all brakes of a train can be brought into action at the same
time fiom any of the waggons or from the locomotive. The construction allows
each brake to be operated itself from the corresponding compartment in which the
brakeman or guard is seated.
In the accompanying Sheet of Drawings, Figures 1 and 2 show my brake as
applied to a railway waggon, while Figures 3 and 4 are details of my Invention.
The brake is shown out of action in the Drawings.
The action of the brake begins when the weight G is lowered, in consequence of
which the lever a lifts the connecting rod 6 which causes the brake blocks to work
against the wheels of the waggon.
The lowering of the weight is effected by the guard by turning the handle c
fastened to the shaft d, the latter being connected with the lever g which has at its
under part a projection upon which iests the roller i of the connecting rod h fastened
to weight G which is kept raised during the time when the brake is out of contact.
By tuining shaft & the lever g disengages the weight G, which drops and brings
the brake into operation. The rod h moves in guides fastened to the front of the
waggon, and is connected with the loop m of the weight G by means of 10llers.
:
To lift the weight and to bring the brake out of action the lever / whose fulcrum
is at r is lifted by the guard by means of a chain s through the levers u and v. The
lever c is now turned, which causes the projection of the lever g to be placed under
the roller i, and so to carry the weight G.
For disengaging all brakes of a train at same time, a cord a is arranged along the
top of all the waggons (see Figures 2 and 4) Each lever g of the break apparatus
is connected to a by means of the cord or cords z, so that by pulling the cord a from
any of the waggons or from the locomotive all the brakes are brought into action at
a tiine.
Instead of disengaging the brakes by levers, winding or screwing up apparatus
may be used
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim,―
Firstly. Working continuous and single brakes in railway vehicles by means
of weights in the manner described, and substantially as shown in the annexed
Drawings.
Secondly. I claim the combination of appliances by which the disengaging and
lifting of weights of railway brakes is effected in the manner described and shown
in the annexed Drawings.
In witness whereof, I, the said Julius Kuntze, have hereunto set my hand
and seal, this Twenty-third day of February, One thousand eight hundred
and seventy-seven.
