I, NICOLAUS SEIDNER, of Soborsin, in the Kingdom of Hungary, Manufacturer,
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 improvement in rope grips for rope tram-
ways and consists in a grip working automatically and able to be used for ropes
of different thickness.
In the annexed drawing an apparatus provided with the bereabove mentioned
improvements is shown in different views and sections namely:-Figs. 1 and 2
show its side and back view when closed. Figs. 3 and 4 show its side and back
view when open. Fig. 5 is a section on the line -. Figs. 6 and 7 illustrate
the automatic disengaging and engaging of the coupling in a mine tramway as
arranged on the guide rail at the loading place in side and front view. Figs. 8
and 9 front and end view of the coupling bolt E. Fig. 10 its section on the
line yy. Fig. 11 plan view of the locking bolt.
The grip or coupling comprises a suitably formed case A for receiving the
different parts of construction and with the cheek O for receiving the rope P.
To a movable sliding piece B in the case A is pivoted the starlike plate C by
means of the shaft D, by means of the spiral springs J lying.in the case it is held
up so that the plate C is remote from the rope P. In this situation of the
apparatus the locking bolt E lies with the recessed part E' in the prismatic down-
ward prolongation of the bore B' of the sliding piece B. When the apparatus is
put together, the spiral spring F and the adjusting ring G are put into the case
through the openings a and b respectively, and then the bolt E is inserted. The
starlike arms of the plate C are provided on their circumference with different
semicircular grooves respectively suitable to the different diameters of various
ropes, in order that the plate may be turned to bring the required groove down-
wards.
The gripping of the rope P is effected as follows:-
Where coupling is to take place the device is guided upon a suitable rail by
means of its rollers y. On the lower part of the rail is arranged an obliquely
lying beam S. As soon as the upper plane of the sliding piece B comes along
the oblique plane the block B with the flat plate C is pushed downwards against
the shoulder O till the axis of the locking bolt E comes into line with the axis
of the circular bore B', whereupon the spring F draws the bolt E with it, till the
adjusting ring G bears against the wall of the case and the round end of the
locking bolt locks the sliding piece B together with the plate C in this position so
that the rope P remains gripped.
When on the other hand a pressure comes upon the projecting four-cornered
end of the bolt E by means of an incline Q suitably arranged wherever uncoupling
is to be effected; the bolt E is pushed so far forwards that its recessed part E
goes into the opening B', the spiral springs J then come into action, lifting the
sliding piece B together with the plate C and releasing the rope.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is:
A coupling device for wire tramways having in a case A a sliding piece carry-
ing a gripping plate C adapted to be lifted by spiral springs J and provided with
a bore B extended prismatically downwardly in which the flattened part E¹ of
a locking bolt E is adapted to enter in the opened position of the gripping device
said locking bolt locking the device in the closed position substantially as de-
scribed.
2. The means for operating the apparatus claimed under 1 comprising an
oblique plane S arranged on the conducting rail by means of which the sliding
piece B is pushed downwards till the axis of the locking bolt E lies in line with
the axis of the circular bore B' of the sliding piece B whereby the spring causes
the bolt to lock the plate B and the plate C presses the towing line P against the
cheek O.
3. An annaratus claimed under I having a flat plate C pivoted upon the shaft D)
provided with any number of arms with different grooves S on its circumference,
according to the different diameters of rope.
4. The means for disengaging the gripping device comprising an incline Q
giving a suitable pressure upon the projecting end of the coupling bolt and per-
mitting the spiral springs J to lift the sliding piece B.
