Improvements in Shaft Couplings or Clutches.
I, EUGEN HABER, of 159, Simmeringerstrasse, Vienna, X., Austria, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in couplings and consists of a drum and
a crank arm or crank disc which can be coupled together or released from each
other, by means of a rod having pivoted at each end a jaw. This rod and jaw are
arranged in the side of the said drum and so connected with the said crank arm or
disc that they will rotate in either direction and assume any chord position as far
as the length of the said rod will allow it.
This I attain for instance by forming a slot in the said rod adapted to receive a
stud fixed to the said crank.
When the said drum and the arm are rotated in the same direction, the said
stud on the said crank arm presses against the said rod; the latter forces the said
to jaws against the drum.
The said rod and jaws not being able to clear owing to the friction caused by
the said jaws the coupling is performed entirely automatically.
When disengaging the coupling the said rod and jaws are displaced through
external force and retained in a position wherein the said jaws will be out of contact
with the drum and can not engage each other.

I, EUGEN HABER, of 159, Simmeringerstrasse, Vienna, X., Austria, Engineer,
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 couplings and consists of a drum and
a crank arm or crank disc which can be coupled together or released from each
other, by means of a rod having pivoted at each end a jaw. This rod and jaw are
arranged in the side of the said drum and so connected with the said crank arm or
disc that they will rotate in either direction and assume any chord position as far as
the length of the said rod will allow it.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings, marked with letters of reference,
showing a side view of my improved shaft coupling or clutch.

page_text: According to one form of my invention I form a slot in the rod P adapted to
receive a stud n fixed to the crank b.
When the drum a and the arm b are rotated in the same direction, through the
force R and the resistance Q, the stud n on the crank arm b presses against the
rod P and the latter forces the two jaws p¹, p² against the drum a.
The rod P and jaws p¹, p² not being able to clear owing to the friction caused by
the said jaws, the coupling is performed entirely automatically.
The force R and resistance Q may also be arranged reversely.
When disengaging the coupling the rod Pand jaws p¹, p² are displaced through
external force in the direction of the arrow and retained in a position wherein the
jaws p1, p2 will be out of contact with the drum a and can not engage each
other.
In lieu of employing the jaws p¹, p² inside of the drum a they may be arranged
to act on the exterior periphery thereof as will be readily understood.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
47
A coupling wherein a system or rod is forced parallel to the plane of rotation
against a drum in such a manner that the said system or rod exerts a pressure in
two directions upon the interior or exterior periphery of the drum, all substantially
as set forth
