page_text: We ALBERT PAUL of 4 Steglitzer Strasse, Berlin engineer and SIMON EHRENWERTH
of 64 Alte Jacob Strasse Berlin merchant 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 car couplings for railway carriages
and wagons and has for its purpose the hooking and unhooking of the same from
outside and thus avoiding the necessity and danger of going between the carriages
when making up a train or shunting. In order to achieve this the links and screws
are held firmly in a line and the whole raised up into a horizontal position by a lever
from the outside and when the next carriage is backed up, the end link of the
coupling falls into the coupling hook.
In order to make this invention more clear, we refer to the accompanying drawings
which form part of this present application and in which similar letters denote
similar parts throughout the different figures.
Fig. 1 is a side view of our improved car coupling raised into the horizontal
position ready to be coupled to the next carriage.
Fig. 2 is a top view of fig. 1.
Fig. 3 is a detail view of the mechanism used for holding the links in a straight
line with the screw.
Fig. 4 is a top view of fig. 3.
Fig. 5 is a side view of the holding mechanism with the screw fully screwed out.
Fig. 6 is an end view of fig. 5.
Fig. 7 is a detail view of the carrier A.
The coupling itself is of the usual form that is a right and left-hand screw working
in nuts to which the links are fastened.
.1
On the nuts B B in which the screw works are fitted the carriers A A (figs. 3
and 7). These carriers are provided with arms a' a' in which the links p
and pp lie, they are also provided with a wing b which fits into the thread of the
screw n. The carriers are fitted to the outside of the nuts in order to allow of the
nuts being brought close together, so that the coupling may be screwed as close up
as possible. There is a notch s' cut in the flange a¹ of the carrier which catches on

page_text: the projections on the end of n' of the screw when the coupling is screwed out, thus
preventing the screw being turned beyond a certain position.
When the links ppppare separated from each other by turning the screw n
the projections comes into the notch sand passes on, on account of the notch being
bovelled and the carrier, rising by the compression of the spring f; for this reason
the hole in the carrier is made oval, but when the collar n has advanced near
enough to the nuts when the projections again catches in the notch s¹, the screw is
prevented from turning any further as the flange n' jams itself hard up against the
nut this occurs at both ends of the coupling.
The spring further serves to hold the flange a² of the carrier down on the top
of the nut in order to prevent the nut from canting when the carrier is lifted by the
projection s.
When the turning of the links is prevented, the whole coupling can be lifted by the
lever arrangement E W. The lever W being jointed to the link p' by the hook o
and the carriages coupled together at any time from the outside.
The hooks lie in the cranked part of the shaft W; the shaft W being journalled
to the wagon in any suitable way.
The shaft W is turned by means of the hand lever H and has a double motion,
one a rotary and the other horizontal; first it must lift the coupling up and then the
loose end of the coupling must be brought to one side in order to allow the link p
passing the hook G; this is rendered possible by making the hole G conical from
both sides. When the carriages are coupled the coupling can be tightened in the
ordinary by turning the screw n. By the oposite movement of the lever H and
shaft W the carriages can be uncoupled.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1) In car couplings the combination of an ordinary car coupling with shaft W,
hand lever H and carriers A A, substantially and for the purpose as described.
2) In car couplings the combination of links p' p¹pp, screw n with projection ss,
nuts B B, carriers A A with slots ss, springs ff, links with rollers o o, substan-
tially and for the purpose as described.
3) In car couplings the combination of the carriers A A having the arms a as,
flanges a¹ a² a³, the flange a¹ having a slot s¹, nuts B B, springs ff, right and left
hand screw n with the heads n having the projections
shaft W, hand lever H, lifting links which carry the rollers oo, substantially
ss, links p, pp', cranked
and for the purpose as described.
