Improvements in Apparatus for Building Cycle and other like
Wire-spoked Wheels.
I, JOHN KAYSER, of Kaiserslautern, in the Empire of Germany, do hereby
declare the nature of this invention to be as follows:-
Wheels with inserted wire spokes, especially cycle wheels, are, by this invention,
constructed with the aid of an adjusting frame, in which an arrangement is provided
for holding the nave of the wheel firm, as well as a groove for inserting the wheel
flange therein, so that the spokes can be drawn through holes in the said frame and
the flange and screwed in. The wheels (the flauges of which are held tightly,
surrounded by the groove of the frame, and cannot therefore get displaced) are
made by this apparatus of equal size and completely circular, the spokes receive an
equal tension, and there can be turned out, by this arrangement, about three times
as many wheels as can be turned out by hand.
In carrying out this invention, the nave of the wheel is so firmly screwed in the
middle of a suitable frame, which is mounted on a suitable stand, that the holes of
the bored nave fit on the holes of the frame flange in the groove of which the wheel
rim is inserted. A bolt inserted through the bore in the nave of the frame prevents
the nave revolving and holds it exactly in the middle of the wheel rim. The wheel
rim is held down in the groove of the frame by binding clamps which are fixed
tight by means of screws, the heads of which can be inserted in annular grooves
formed in the frame.
The wire spokes can now be drawn through holes in the frame and through holes

four spokes at right angles in order to prevent the central bolt aforesaid from
drawing out of the middle, and then one spoke after another can be drawn as tight
as is possible without extra expenditure of strength.
When all the spokes are screwed in, the clamps are removed and the wheel
removed from the frame by means of suitable key screws.
In order to give the central bolt on which the nave of the wheel is placed a still
firmer position, it can be pressed down from above by means of a head screw which
passes through the boss of a cross arm; the latter is affixed to the inserting frame
by means of screws.

provided in the frame an arrangement for securing the nave of the wheel as well as
a groove in which to insert the wheel rim, so that the spokes can be drawn and
screwed through holes in the frame and the wheel rim.

produced are all exactly equal in size and are exactly circular, the spokes receive
an equal tension, and about three times as many wheels can be made by the aid of
this apparatus as can be made by hand. The manipulation of the apparatus is so
simple that cheap labour can be employed.

Improvements in Apparatus for Building Cycle and other like
Wire-spoked Wheels.
1, JOHN KAYSER, of Kaiserslautern in the Empire of 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 :-
Wheels with inserted wire spokes, especially cycle wheels, are, by this invention,
constructed with the aid of an adjusting frame, in which an arrangement is provided
for holding the nave of the wheel firm, as well as a groove for inserting the
wheel rim therein so that the spokes can be drawn through holes in the said
frame and the rim, and screwed in. The wheels (the rims of which are held
tightly, surrounded by the groove of the frame, and cannot therefore get displaced)
are made by this apparatus of equal size and completely circular, the spokes
receive an equal tension, and there can be turned out by this arrangement about
three times as many wheels as can be turned out by hand.
Figures 1 to 3 of the drawing show respectively an elevation, section and a
detail of the same.
The nave of the wheel is firmly screwed in the middle of the frame R, which
is mounted on a suitable stand A. The wheel rim d is inserted in the grooves of
the frame flange c. The holes of the bored nave and those in the frame flange c
and wheel rim lie in such relative positions that the wire spokes e can be drawn
through the respective holes, one after another, to form the radial spokes of the
wheel. A bolt a, inserted through the bore in the boss of the frame R, prevents
the nave revolving and holds it exactly in the middle of the wheel rim. The
wheel rim is held down in the grooves of the frame R by binding clamps, which
are fixed tight by means of screws, the heads of which can be inserted in annular
grooves formed in the frame.
"
The wire spokes e can now be drawn through the holes in the frame R and
through the holes arranged to communicate therewith in the wheel rim d. It is
desirable to first insert four spokes at right angles in order to prevent the bolt a
from drawing out of the middle, and then one spoke after another can be drawn as
tight as is possible without extra expenditure of strength.
When all the spokes e are screwed in, the clamps are removed and the wheel
removed from the frame R by means of the key screws i
In order to give the bolt a, on which the nave of the wheel is placed, a still
firmer position, it can be engaged from above by means of the headed screw k
which passes through the boss of the cross anng the latter is affixed to the
inserting frame by means of screws.
The clamps can also be pressed on by the action of a lever or eccentric; the
manner of doing this is unimportant.
A special adjusting frame R is used for each size of wheel. It can, if desired,
be divided, and its parts, by means of supports which can be simultaneously moved
towards the centre, be adjusted to every size of wheel. But such an arrange-
ment is equal in cost to making several apparatus to suit various sizes of wheels
and is much less durable. It is only essential for a successful result that there be
provided in the frame K an arrangement for securing the nave of the wheel as
well as a groove for inserting the wheel rim d, so that the spokes can be drawn and
screwed through holes in the frame and the wheel rim.
Among the practical advantages of this apparatus may be named the wheels
produced are all exactly equal in size and are exactly circular, the spokes receive
an equal tension and about 3 times as many wheels can be made by the aid of this
apparatus as can be made by hand. The manipulation of the apparatus is so simple
that cheap labour can be employed.

page_text: 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. An apparatus for building cycle and other wire-spoked wheels, consisting
of a frame R having a nave for receiving a bolt a and holding firm the wheel
hub, and having also a flange with groove s adapted to surround the wheel
rim d when the latter is inserted therein, in such a way that the spokes e can be
drawn through the holes in the wheel rim and screwed up to the required tension,
substantially as described.
2. In the apparatus set forth in claim 1 :—
(a) The clamps adapted to be pressed down on the wheel rim by means
of screws the heads of which can be inserted in annular grooves u
formed in the frame flange e, substantially as described.
(4) The cross arm g capable of being firmly fixed to the flange e with a head
screw for securing the nave bolt a, substantially as set forth.
