I, ALEXANDER POST, of Eilpe near Hagen, kingdom of Prussia, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
My invention relates to belt-couplings principally designed to be used with belts
that are made of woven fabrics, and it consists in the construction of a coupling
whereby the ends of the belts can be securely connected together without damage to
the same, which adapts itself to pulleys of small diameter, and which operates with
like friction on the surfaces of the pulleys as the belt. itself."
The said coupling comprises two leaves hinged together and two separate.counter-
plates, the former bearing from the outside, the fatter from the inside on the
belt-ends, and the corresponding parts being fastened together by screws pissing
through the belt. In order to produce a firm grip of the leaves on the ie, the
bearing-surfaces of the same are roughened or provided with small corrugations, and
the counter-plates may have like bearing-surfaces. On the outer side the said
counter-plates are lined with leather or other material adapted to produce the
necessary friction on the pulleys. Preferably the leaves as well as the counter-plates
are curved so as to form segments of cylinders. If desired, each coupling-para may
be composed of two or more leaves hinged together and of the corresponding counter-
plates.

Improvements in Belt-couplings.
1, ALEXANDER POST, of Eilpe near Hagen, kingdom of Prussia, 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 :-
My invention relates to belt-couplings principally designed to be used with belts
that are made of woven fabrics, and it consists in the construction of a coupling
whereby the ends of the belts can be securely connected together without damage to
the same, which adapts itself to pulleys of small diameter, and which operates with
like friction on the surfaces of the pulleys as the belt itself.
.
The said coupling comprises two leaves hinged together and two separate counter-
plates, the former bearing from the outside, the latter from the inside on the belt-ends,
and the corresponding parts being fastened together by screws passing through the
belt. In order to produce a firm grip of the leaves on the belt, the bearing-surfaces
of the same are roughened or provided with small corrugations, and the counter-
plates may have like bearing-surfaces. On the outer sido the said counter-plates are
lined with leather or other material adapted to produce the necessary friction on the
pulleys. Preferably the leaves as well as the counter-plates are curved so as to form
segments of cylinders. If desired, each coupling-part may be composed of two or
more leaves hinged together, and of corresponding counter-plates.
In the annexed drawings Fig. 1. is a transverse section and Fig. 2 a plan of a
coupling carried out according to my invention. Fig. 3 represents a coupling with
double leaves.
In Fig. 1, F is a belt running on the pulley E. A B, Figs. 1 and 2, are the leaves
of the coupling hinged together at a, and CD the counter-plates. The said leaves
and the corresponding plates are fastened together on the ends 6 b₁ of the belt by
the screws; and for increasing their grip on the belt, their bearing-surfaces are
provided with small angular corrugations. c c are linings of leather fixed to the
plates CD by means of pins or spurs formed upon the latter. Both, the leaves and
the counter-plates are curved in the manner shown by the drawing, a suitable cavity
being thus produced in the plates CD for receiving the lining c, while at the same
time this curvature causes the portious d of the belt, being close to the parts of the
coupling, to be pressed against the pulley.
In the coupling shown by Fig. 3, each part thereof consists in two leaves A A¹
and B B, and in the respective counter-plates-CC and D D¹, the leaves of either
part being hinged together in like manner as the leaves A and B. This coupling is
designed to be used with belts serving for the transmission of very considerable
forces.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is.
1. In a belt-coupling, the combination of two or more leaves hinged together and
having roughened bearing surfaces, two or more counter-plates lined with leather or
other equivalent material, and screws whereby the leaves and the corresponding
plates are fastened to each other on the belt, substantially as described.
2. In a belt-coupling the combination of two or more leaves hinged together and
having roughened bearing surfaces, two or more counter-plates lined with leather
or other equivalent material, and screws whereby the leaves and the corresponding
plates are fastened to each other on the belt, the said leaves and plates being curved
so as to form segments of cylinders, substantially as specified.
