COMPLETE SPECIFICATION.
A New or Improved Apparatus for Cutting Out Plaster Bandages
and the like.
I, JEAN OTT of Mayence in the Empire of Germany do hereby declare the
nature of this invention and in what manner the saine is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to an apparatus for cutting out plaster bandages and the
like by hand. It consists essentially of a small circular saw revolubly mounted on
a holder capable of being held by the fingers of the hand, and receives its cutting
movement by means of a lever mounted on the axis of rotation of said saw through
the intermediary of a spring catch or pawl.
This improved apparatus is shown in the accompanying drawing :--
Figure 1 being a side elevation;
Figure 2 au eud view;
Figure 3 a partial end viow showing the circular saw in section;
Figures 4 and 5 views slowing a modified form of the spring-catch or pawl.
The saw holder a, which is made of suitable metal, is formed at its lower edge
as a guide and support a' for the plaster-bandage which is to be cut out, and at its
upper side with a handle having preferably two finger loops. At each side of this
holder, bars bare fastened which carry at their front end a small spindle c. On
this spindle there is arranged a circular saw e and a forked lever d enclosing the
circular saw and provided with a handle or finger loop. A spring catch or pawl d¹
is suitably fixed on one side of said lever d and the spring of this catch or pawl
may either be directly cut out of the body of the lever or a separate spring
attached to the lever, as shown in Figures 4 and 5. The end of the spring catch
or pawl is bevelled and engages in holes e' in the circular saw. If the lever d be
turned to the left as indicated by arrow 1, the circular saw e is revolved by the
spring catch or pawl, and if turned to the right as indicated by arrow 2, the spring
catch or pawl slides with its bevelled surface out of hole e' in which it was engaged
and over the surface of the circular saw into tho next succeeding hole e', the
circular saw in the meantime boing held or retained by friction between the two
metal bars b.
The operation of the apparatus is as follows:-
The holder a is held in the haud and the lever d moved to and fro with one
finger, preferably the index finger, thereby causing the saw to revolve inter-
mittently and the plaster bandage or the like which is held between the saw and
the guide piece a¹ is cut out.
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 :-
An apparatus for cutting out plaster bandages and the like by hand, consisting
of a circular saw (e) revolubly mounted in a holder (a). said saw receiving an

pawl (d) substantially as herein before described and shown in the accompanying
drawing.
