PROVISIONAL SPECIFICATION.
Improved Tool for Bending, Notching, and Cutting Metal
Bandage Bars.
1, Dr. EMIL STENDEL, of No. 29 Hirschstrasse, Karlsruhe, Baden, Germany, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a universal tool for rapidly bending straight rectangular
metal bars more particularly those of aluminium to be used with bandages, so as to
bring them into the proper form required to fit the limb for which it is to serve as
a splint or support, and for making notches or tooth-like projections on that side of
the bar which is situated away from the wound as also for cutting the bar into the
required lengths.
For these purposes the tool is constructed of two pivotted limbs constituting a
pair of pliers, the limbs being so connected to their pivot as to be readily separable
from each other, for which purpose the pivot is fixed to the one limb and fits with a
lense-shaped conical head into a corresponding hole in the other limb when this is in
A certain position, so that on then slightly turning the tool, the pivot secures the
two limbs together. The only position of the two limbs in which the connection
and disconnection as described can be effected, is when they are opened out to the
widest extent, so that in every other position they are locked together. Between
the limbs is arranged a spring which opens them out again when they have been
pressed together, a spring catch being provided at the end of the limbs for locking
them in the closed position.
The head of the one limb has a rearward projection in which is formed a
rectangular slot, and the head of the second limb has also a rearward projection
with two such slots at right angles to each other, which slots correspond in size to
the sizes of the bandage bars to be treated, the said bars being inserted into the
slots so as to be firmly held thereby and thus enable the bar to be bent by pressure
or by hammering into any desired shape. When it is desired to twist the bar
round its longitudinal axis, the two limbs of the tool are detached from each other
and the one end of the bar is inserted into the slot of the one limb and the other
end into the slot of the other limb, so that by the leverage afforded by the two limbs
the bar can then be readily twisted.
Instead of the above mentioned openings in the heads of the limbs, any greater
or less number may be provided, and they may be of any desired configuration.
Each limb is provided with a cutter jaw on the inner side of the pivot for cutting
off lengths of the bar such cutter jaws being preferably made changeable.
For forming notches, projections or teeth on the bar, which serve to afford
a secure hold for the bandage, the head of each limb is provided with pressing
cheeks, which may be formed with one or more pressing surfaces for acting upon
bars of different widths. These surfaces are formed with teeth which, on being
forced against the edges of the bar, raise up portions of the metal therefrom so as
to form teeth and notches thereon, the other edges of the bar which are to lie
opposite the wound being left flat.

Bandage Bars:
I; Dr. EMIL STENDEL, of No. 29 Hirschstrasse, Karlsruhe, Baden, Germany,
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 a universal tool for rapidly bending straight rectangular
metal bars more particularly those of aluminium to be used with bandages, so as to
bring them into the proper form required to fit the limb for which it is to serve as
a splint or support, and for making notches or tooth-like projections on that side of
the bar which is situated away from the wound, as also for cutting.the bar into the
required lengths.
a
For these purposes the tool is constructed of two pivotted limbs constituting
pair of pliers, the limbs being so connected to their pivot as to be readily separable
from each other, for which purpose the pivot is fixed to the one limb and fits with
a lense-shaped. conical head- into a corresponding hole in the other limb when this
is in a certain position, so that on then slightly turning the tool, the pivot secures
the two limbs together. The only position of the two limbs in which the connection
and disconnection as described can be effected, is when they are opened out to the
widest extent, so that in every other position they are locked together. Between
the limbs is arranged a spring which opens them out again when they have been
pressed together, a spring catch being provided at the end of the limbs for locking
them in the closed position,
The head of the one limb has a rearward projection in which is formed a
rectangular slot, and the head of the second limb has also a rearward projection
with two such slots at right angles to each other, which slots correspond in size to
the sizes of the bandage bars to be treated, the said bars being inserted into
the slots so as to be firmly held thereby and thus enable the bar to be bent
by pressure or by hammering into any desired shape:
When it is desired to twist the bar round its longitudinal axis, the two limbs of
the tool are detached from each other and the one end of the bar is inserted into
the slot of the one limb and the other end into the slot of the other limb, so that
by the leverage afforded by the two limbs the bar can then be readily twisted.
Instead of the above mentioned openings in the heads of the limbs, any greater
or less number may be provided, and they may be of any desired configuration.
Each limb is provided with a cutter jaw on the inner side of the pivot for cutting
off lengths of the bar such cutter jaws being preferably made changeable.
The construction of the said tool is shewn at Figures 1 to 3 on the accompanying
drawing of which
Figure 1 shews a front view of the tool, Figure 2 a side view,.part front view
and section on line I-II of the one limb detached.
Figure 3 shews a side view of the other limb detached and also a part front
view of the pivot device of both members and sections respectively on lines III-IV,
and V-VI.
Figure 4 shews a plan, side view and cross section of part of a bandage bar
notched by means of the tool.
The two limbs a and b forming the tool are pivotted together by a stud c in such
manner as to be readily detachable from each other.
The pivot stud c is attached to the limb a and has a lenticular shaped head d
tapered inwards, which in a certain relative position of the limbs, can be inserted

page_text: into a correspondingly shaped opening e of the other limb b, while by a slight
relative motion of the limbs from that position, the pivot effectually locks them
together.
The insertion of the head d into the opening e is effected when the limbs are
opened out to a certain extent, in which position the opening e in the limb b will be
situated exactly over the head d.
Thus it is only when in this position that the two limbs can be separated from
each other, they being securely held together in every other position. The springf
serves to open the jaws of the limbs automatically after they have been pressed
together, while the catch at the lower end serves to hold them in the closed
position.
:
The head a¹ of the limb a is formed with a rectangular slot g, and the head b¹
has two such slots g g which correspond to the sections of the bandage bars to be
treated.
These are inserted into the said openings so as to be held securely thereby and
by then pressing or hammering the other end of the bar, or holding it in a vice it
can be bent into the desired shape.
In order to enable a bar to be also twisted round its longitudinal axis, the two
limbs are separated in the above described manner, and the bar is introduced with
its two ends respectively in a slet of each limb whereupon the bar can be readily
twisted or bent by means of the leverage afforded by the handles of each of the
limbs. Instead of the slots shewn, others of different form may of course be
provided, either in greater or in smaller number.
Below the pivot care provided two cutters h, for cutting the bars to the required
length, such cutters being by preference made interchangeable.
For producing notches, projections or teeth, serving to hold the bandages
securely, the jaws of the tool are provided with pressing cheeks i. As shewn,
these are formed with two pressing places k and k¹, k serving to notch wider bars
and narrower ones. The pressing cheeks are so formed and provided with
teeth that they only form notches m and projections n on the one side of the
bar, as shewn at Figure 4, the edges on the other side, which is to be opposite the
wound, being left smooth.
The pressing cheeks or the teeth 1 can of course be of any other form in order
to produce different forms of projections and notches; also, instead of there being
two, there may be only one or more than two pressing cheeks and pressing places,
with a greater or fewer number of teeth 1 l.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A tool for notching or forming teeth on bandage bars wherein the jaws of the
tool are provided with pressing cheeks i that are so formed and provided with
teeth, as to produce notches m and projections n on the edges of one side of the
bar, while those of the other side are left smooth, substantially as described.
2. In a tool such as is referred to in the first claim providing the limbs with
openings such as g g', g' in addition to the pressing cheeks i for the purpose of
bending or twisting the bandage bars either before or after notching them,
substantially as described.
