PROVISIONAL SPECIFICATION.
Disengaging Gear for Straps or Belts.
| FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, as
communicated to me by Robert Kuner of Ebersbach, in the Kingdom of Saxony,
Germany, Cycle Manufacturer, to be as follows:-
the
This invention relates to apparatus for disengaging belts or straps to be used instead
of loose pulleys. Substantially the new mechanism is a semi-star, laid upon
same shaft and just beside the driving pulley, and the various rays of which carry
pulleys adjustable radially.
When disengaging the belt, it is thrown upon these pulleys by means of a
belt fork.
The semi-star is loose upon the shaft of the driving pulley but fixed by two of
its rays to overhead brackets. The arms of the semi-star are provided with
radial slots allowing the adjustable pulleys to be placed in a suitable circle to
receive the belt from the driving pulley or to place it thereupon. The belt when
running over the loose pulleys of the semi-star has no tension which involves
saving of wear and tear, and dispenses with an overhead motion with machines
without conical pulleys, because the driving power of a machine can be directly
taken from the gearing, and disengaging the driving power can be done also on
the gearing by the above described semi-star.
A great advantage of this disengaging gear is the easy running of the belt upon
the loose pulleys, without any tension; further, the adjustability of the pulleys,
makes the disengaging gear adaptable to work with driving pulleys of different
diameters. Moreover, the apparatus is suitable for machines, which do not allow
of their being thrown out on the side of the gearing. The semi-star in that case,
must be directly fixed beside the pulley of the machine.
For dynamo machines especially, this feature will probably prove to be
valuable, as a belt which is tensionless when not in work, has less wear and tear
than one that is always in tension.

COMPLETE SPECIFICATION.
Disengaging Gear for Straps or Belts.
I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Robert Kuner of Ebersbach in the Kingdom of Saxony,
Germany, Cycle Manufacturer, 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 an apparatus for disengaging belts or straps, to be used
instead of loose pulleys. Substantially the new mechanism is a semi-star, laid
upon the same shaft and just beside the driving pulley, and the various rays of
which carry rollers or pulleys adjustable radially.
On the accompanying drawing-
Figure 1 is a front view and Figure 2 a side-view of the disengaging gear;
Figure 3 shews a detached view of part of one of the rays a of the semi-star
with the roller or pulley affixed thereto.

page_text: The semi-star has a nave A which is loose upon the shaft B of the driving
pulley C and two of the rays or arms a of the star are fixed to overhead
brackets. The arms a are provided with slots a' in which the rollers or little
pulleys care carried by means of screw pins thus allowing the pulleys to be placed
in a suitable and variable circle to receive the belt D from, or to place it upon the
driving pulley C by means of a shifting belt fork d.
The strap or belt being short, it is advantageous to place the rollers c obliquely
to the strap in order to draw away the strap laid upon the rollers from the driving
pulley.
A great advantage of this disengaging gear is the easy running of the belt upon
the loose pulleys e without any tension, further, the adjustability of the pulleys
makes the disengaging gear adaptable to work with driving pulleys of different
diameters. Moreover the apparatus is suitable for machines, which do not allow
of their being engaged and disengaged on the side of the gearing. The semi-star
in that case, must be directly fixed beside the pulley of the machine.
Having now particularly described and ascertained the nature of this said inven-
tion and in, what manner the same is to be performed, I declare that what I
claim is :-
A disengaging gear for straps or belts, consisting of a semi-star, the arms of
which are slotted and carry rollers or pulleys c which can be adjusted in a suitable
and variable circle, the said semi-star being placed loose upon the driving shaft B
beside the driving pulley C by means of a nave A substantially as described.
