COMPLETE SPECIFICATION
Improvements in Coupling-devices for Rolling Stook.
We, SALLY WEILL, of No 10, Garten Strasse, Merchant, and CUNT WITZ-CHEL,
of No. 11, Trier Strasse, Architect, both of St Johann, in the Empire of Germany,
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.―
The present invention relates to an improved coupling-device for rolling stock
in which the coupling of the cars is effected in an automatic manner, whilst
uncoupling of the cars can be effected from the side of the cats, thus rendering
it unnecessary for a man to stand between the cais.
We are aware that devices of this kind have been constructed before, our inven-
tion however distinguishes itself by not only providing a reliable coupling between
the various cais, but by providing means for allowing the coupling a certain
amount of play in accordance with the requirements of the rolling stock.
The coupling hooks can be fixed at any desired and suitable height and are
constructed in such a manner that they are applicable for cais of any kind
With these ends in view our invention consists in certain novel features of
construction and combinations of parts hereinafter described
We will now proceed to describe our invention more fully, reference being had
to the accompanying diawings, which form part of this specification, and in which
Fig 1 is a plan view of the coupling device.
Fig 2 18 a section on line A-B of Fig 1
Fig 3 is a section on line C-D of Fig. 1 and
Fig 418 a section on line E-F of Fig. 1
The coupling device proper consists of a hook arranged below the car body a
between the buffers in the direction of the axis of the train Said hook rests
in a suitable guide bracket c, in which it is movable as indicated in the various
figures.
The shaft of the hook is composed of two parts hinged together by a joint d.
The reduced front part e of the shaft is swivelled in a bore in the socket f,
arranged beneath the car body, in such a manner that it is fieely rotatable around
its axis and movable longitudinally with the socket f, as will be more fully
described later on. The front end of the socket f 18 mounted on a sciow gigidly
secured to the car structure in any suitable way
A toothed wheel on the center of the socket f, meshes with a pinion ‹, said
pinion being 1otated from the side of the cai by means of the hand wheel n,
the 1od m and the bevel wheels /
The shafte of the coupling hook at the central portion has its perimeter fitted
with teeth p, the latter engaging with a lack o which 18 movable fiom outside
the buffers & by means of handles, levers, hand wheels or a similar suitable device.
The rack o and the toothed portion of the shaft e are geared in such a
manner that one complete movement of the rack o causes the shaft e to rotate
around its longitudinal axis through an angle of 90°.
The font part of the coupling shaft can be adjusted in altitude by a suit-
able lever aangement r By combining a locking segment in con-
nection with the lever arrangement r, the latter may be retained and locked in
each respective position In Fig 2 the arrangement of the lever r and its
appended parts are clearly indicated.

page_text: The coupling hooks is provided with two bearing surfaces t, u and it is obvious
that whilst the nose of the hook at the end of one car points downwards, the nose
of the hook at the end of the adjacent care to be coupled to it has to point upwards
to ensure engagement
The rack o and the pinion p of the shaft e previously described, which form
the reversing device for the coupling hook to ensure the proper position of the
two hooks of two adjacent cars are suitably in connection with an indicator disc v
rotatable vertically to indicate the respective position of the coupling hook.
It is evident that in the normal position the coupling hook at the back of one car
points with its nose downwards, whilst the coupling hook at the front of the adjacent
car to be coupled to it points with its nose upwards On moving the cars together
the hooks meet and glide upon one another, until they lock. The movement of the
hooks upon one another is limited as required by the buffers b of the two cars
heeting. Should the hooks not lock tightly, when the buffers press upon one
another, turning of the hand wheel laterally of the car will cause the swivel-
socketf to move either for wards or backwards on the screw g by the agency of
the rod m and bevel wheels /k-previously referred to. The longitudinal move-
ment of the socket fcauses the coupling-hook shaft to advance or retire as required
for the purpose of ensuring tight focking of the two coupling hooks
.
Should two cais of different height or a loaded and an empty can have to be
coupled together, by means of the lever arrangement r, previously described, the
altitude of one of the coupling hooks can be varied to meet the requirements."
When the indicating discs vindicate the two coupling hooks to be in uniform
position, moving the transverse lack by means of its handle will cause 'the
coupling shaft, and with it the coupling hook, to be rotated to an angle of 90°,
when the hook will be in the proper position for operation By suitable gearing
the indicating disc v is rotated to an angle of 45° during the said rotation of 90°
of the coupling shaft. The co-operation of the indicating disc rod with 'the
coupling shaft is suitably effected by means of cogged wheel gear.
__
Uncoupling of the cars when shunting is effected in the following manner:
The buffers b being pushed together, the noses of the coupling hooks 'will separate
and on now depressing the handle of the lever their complete disengagement
will be ensured by the turning of the coupling shaft q around its pivot d which
causes the respective hook to be raised in its guide bracket, whereupon the
cais are free to separate. After uncoupling the coupling shaft is again
brought back to its normal position by releasing the lever r
Supposing it to be required to uncouple the cars when they are in a position
of rest, turning of the hand wheel n and its motion-transmission gear, as herein-
before descubed, will cause the separation of the noses of the coupling hooks
sufficiently to thereupon raise one of the coupling hooks 'by means of the lever r
as described in the previous paragraph.
The hooks s being journaled so as to be rotatable only to the required extent
at a time, their proper and reliable engagement will be attained without difficulty,
no, further turning being possible at the two extreme positions.
Having now particularly described anu ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim 18.-
Coupling and uncoupling device for railway cars, the whole constructed arranged
and adapted to operate, substantially as described with reference to the accom-
panying drawings.
