Year: 1884

I, FELIX BAUMANN, engineer, of Kohlscheid, Prussia, do hereby declare the
nature of my 'Invention for "IMPROVEMENTS IN BELT-FASTENERS," to be as
follows:
The improved belt-fastener is composed of two rotary cylindrical bodies which
are excentrically connected together by means of one or more ties. The ends of the
belt to be fastened are passed between the said bodies and are seized firmly thereby,
upon turning the same.
The cylindrical bodies are bollow so as to reduce the weight of the fastener.
The ties may be placed inside or outside of the cylindrical bodies; in either case,
the ends of the belt to be fastened are made with slots which correspond to the
thickness of the said ties.

page_text: I, FELIX BAUMANN, engineer of Kohlscheid, Prussia do hereby declare the
nature of my invention for IMPROVEMENTS IN BELT-FASTENERS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The improved belt-fastener is composed of two rotary cylindrical bodies which
are excentrically connected together by means of one or more ties. The said
rotary bodies are made hollow with a view of reducing the weight of the belt-
fastener. The rotary bodies are suitably slotted or arranged for the reception of
the ties, see Figures 1, 2 & 3, and the ends of the belt are correspondingly slotted.
The stops on the cylindrical bodies limit the throw id est maximum and
minimum opening or space between the two gripping cylinders.
For introducing the ends of the belt into the fastener, the rotary bodies are
brought into the position shown in figures 2 & 3, thereupon the said bodies are
rotated until they come in contact with the belt, as shown in fig. 1. Upon
stretching the belt, the said bodies approach each other more and more and grip
the belt ends between them, the tighter the belt, the stronger the grip. Fig 2ª & 3ª
show the utmost tightening of the belt.
The rotary bodies and the ties are allowed a little play, for the proper working
of the fastener. The ties may be one or more in number,
Fig 3b shows a belt-fastener with one single tie, arranged centrally.
Fig 2b shows a belt-fastener with two ties, arranged externally.
Fig 1 shows a belt-fastener with two ties arranged internally.
Fig 3 & 3* are vertical sections; the remaining figures are side and top views.
The main advantages of the belt-fastener as compared with belt-fasteners of
other kinds, are the following: first the rapidity with which the connexion and
disconnexion can be made; second the limited maximum and minimum opening
third the facility with which the fastener can pass over small pullies; fourth the
possibility of utilizing the belt-fastener with belt-shippers and on pullies having
turned up edges, without striking against the same; fifth the parts being movably
connected with somewhat play, the ends of the belts are bound to be securely
held, irrespective of any unevenness in the thickness thereof, sixth the belt ends
are not damaged & weakened by holes, staples and such like, and cannot be
tightened to a greater extent than is permitted by the tightness of the belt itself.
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
The herein before described belt fastener composed only of two cylindrical
excentrical bodies connected by means of one or more ties with somewhat play
and without the use of any framing, the said fastener acting automatically by the
tightness of the belt.
