An Improved Machine for Bending Fluted Metallic Strips.
I, FELIX KLINGELHÖFER, of 4 Beaumont Crescent, West Kensington, in the
County of London, Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to an improved machine for bending fluted metallic
strips, to be used in the construction of spokes for wheels described in my
Specification No. 22192, bearing date November 20th, 1893, or for any other
contrivance.
This invention is constructed of an elongated triangular shaped frame with a
base or flange at the point for bolting the machine to any fixture. At or near this
point is pivoted two long iron straps perforated at the other ends to receive bolts.
To these said straps are pivoted a forked hand lever with a roller for the purpose
of the said roller (when the lever is pulled over and around the top of the machine)
pressing the inside of the fluted material into the fluted groove formed around the
frame. The frame is provided with a detachable plate or plates so as to remove
the bent fluted piece of metal after the operation is performed. The detachable
plate or plates are fixed on the frame by means of bolts. Wedges are attached
to the frame by set screws for securing the fluted metal to several parts of
the frame as the operation is being performed along the groove cut in the three
sides of the said frame. The two top corners of the frame are rounded off.
Clearing holes are provided through the detachable plate or plates and frame,
where necessary for pivoting the forked hand lever when the roller is turning each
rounded off corner of the hereinbefore described frame.
Other plates may be introduced between the detachable plates to enable me to
make various sizes of spokes.

An Improved Machine for Bending Fluted Metallic Strips.
I, FELIX KLINGelhöfer, of 4 Beaumont Crescent, West Kensington, in the
County of London, Engineer, 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:-

My invention relates to an improved machine for bending fluted metallic
strips, to be used in the construction of spokes for wheels described in my
Specification No. 22192, bearing date November 20th, 1893, or for any other
contrivance.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.

The
This invention is constructed of an elongated triangular shaped frame e with a
base flange or wall plate a at the point for bolting the machine to any fixture. At
or near this point is pivoted on a centre pin n two long iron straps d perforated at
the other ends to receive bolts j. To these said straps d are pivoted a forked hand
lever i with a roller c for the purpose of the said roller c (when the lever i is
pulled over and around the top of the machine) pressing the inside of the fluted
material or steel strip 6 into the fluted groove o formed around the frame e.
frame e is provided with a detachable plate or plates so as to remove the bent
fluted piece of inetal after the operation is performed. The detachable plate / or
plates are fixed on the frame by means of bolts p. Wedges q are attached to the
frame e by set screws for securing the fluted metal to several parts of the frame e
as the operation is being performed along the groove cut in the three sides of the
said frame. The two corners or curves hands of the frame are rounded off.
Clearing holes and g' are provided through the detachable plate or plates
and frame e, where necessary for pivoting the forked hand lever i when the
roller e is turning each rounded off corner of the hereinbefore described frame.
Other plates of a number of sizes may be introduced between the detachable
plates to enable me to make various sizes of spokes as shown in dotted lines t in
Fig. 6.
с
It will be understood that I do not bind myself to construct the aforesaid
apparatus strictly to what has been described herein, as it is evident that I may
vary the shapes of any of the parts in many ways within the scope of my
invention.
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 :-

1. In a machine for bending fluted metallic strips, the combination of the wall
plate a roller c straps d grooved triangular shaped frame e centre pin holes
and g curve forked hand lever i set screws or bolts j curve k detached plate
centre pins m and n with the fluted groove o bolts p wedges 7 set screws r
curves, substantially as herein described and according to the accompanying
drawings.
2. In a machine for bending fluted metallic strips, the combination of the
various parts of the apparatus as illustrated in the accompanying drawings and
described in the above specification.
3. In a machine for bending fluted metallic strips, the combination of the
various parts of the apparatus and a plate t or plates inserted between the
detachable plate and grooved frame e to make any size spoke for a wheel,
substantially as herein described.
