Improvements in Spanners for Machines and Devices of all Kinds,
particularly applicable for Cycles and Automotors.
We, CARL MARSCHÜTZ and HEINRICH MARSCHÜTZ, both of Fürtherstrasse,
Nuremberg, in the Kingdom of Bavaria, and German Empire, Directors of Manu-
facturing Works, 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 new spanner for machines and other devices, is par-
ticularly applicable for cycles and auto-motors, and which is adapted to nuts and
screw heads of various sizes, without alteration of the mouth of the spanner.
Further the spanner is constructed to fold into a small compass, but when in use
it has sufficient mechanical advantage and rigidity to do the work effectively.
Therefore it answers especially the requirements for cycles and auto-motors, but
when constructed of suitable proportions it is also useful for erecting machinery
and in engineering work generally.
In order that this invention may be the better understood-I now proceed to
describe the same reference being had to the accompanying drawings an! to the
letters and figures marked thereon.
Figures 1 and 2 are views of the spanner when folded to be put away.
Figures 3 and 4 show different positions of, the spanner when in use.
The several arms or members a which may be of any suitable shape and size
of jaw or hole are connected at one extremity so as to pivot by a bolt c or a rivet,
screw or other device and a shoulder piece b.
Thus the
For putting away, the arms or members a are folded towards one side, as shown
in Figures 1 and 2. For use, the member of the desired size of jaw or hole (a' in
the drawings) is turned through about 180° as shewn in Figure 3.
spanner has double the leverage of the separate members, the members not used
for screwing serve as a convenient handle.
The back of the shoulder piece b is sufficiently broad to serve as a counter sup-
port to prevent the folding up of the extended spanner.
If desired the shoulder d of the piece b may be somewhat elongated and have
a slot and a square or other hole to serve as a nozzle spanner and for similar
purposes.
Further the spanner may be provided with a screw driver f, Figure 4. For use
as a screw driver several members a are extended, and the screw driver fis turned
so that it forms a right angle to the members a, the latter serving as a handle.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we claim
is;-
1st. A spanner having a number of members a held together at one end by a
piece b and a pin or similar device, so as to fold for putting away, and to offer
the leverage of the lengths of several members when in use.

page_text: 2nd. A form of construction of the spanner claimed in Claim 1 in which the
piece is shaped and has a broad shoulder to serve as a counter support for the
opened spanner when used.
3rd. A form of construction of the spanner claimed in Claim 1 in which the
shoulder of the piece bis elongated and has one or more holes or recesses for
screwing suitable parts.
4th. A form of construction of the spanner claimed in Claim 1 in which a screw
driver is arranged beside the members a so that the members a serve as a
handle for the screw driver.
