page_text: I, HERMANN ADOLPH REINHOLD, of 7, Wellington Street, Woolwich, in the
county of Kent, Engineer, do hereby declare the nature of this invention to be as
follows:-
--
My invention relates to wheels of that class known as tension wheels and chiefly
designed for velocipedes.
-
In wheels of this class as heretofore constructed the spokes frequently break owing
to the fact that they are rigidly screwed into or attached to the hub.
The chief object of my invention is to obviate this breakage and to this end I
attach the spokes to the hub by loose connections so that any strain applied to the
bub will be equally divided between the spokes whereby no undue strain will be felt
by any one spoke.
In carrying out my invention I employ in conjunction with each spoke a nipple
one end of which is adapted to engage with the spoke, while the other end is provided
with an eye through which a pin or screw can be passed to secure it to the hub. In
some cases the nipple is provided with an internally screw threaded socket adapted to
receive the end of the spoke and in other cases an internally screw threaded socket is
screwed to the nipple; in the latter cases the end of the spoke is provided with a head
to prevent it from slipping out of the socket.
In order to apply the nipples to the hub I form circumferential slots or grooves in
the peripheries of the flanges of the said hub, the said slots or grooves being at an
angle corresponding to a line extending from the centre of the wheel rim to the
centres of the flanges. This angle however will vary according to the diameter of the
wheel to which my improvements are applied. Around the faces of the flanges are
formed holes through which the pins or screws which pass through the eyes of the
nipples can be passed.

page_text: A wheel built on this plan gives direct and equal strain to each spoke, as the spokes
being hinged at the point where they receive their power give to every thrust of the
pedal keeping the strain of the spokes in a direct line, whereas in an ordinary wheel
every vibration is felt at the points where the spokes are screwed into the boss at
which points they usually get loose or break off.
A great advantage of my invention in addition to those before indicated is that if a
spoke accidentally breaks or becomes damaged it may be readily replaced without
injury to the hub.

I, HERMANN ADOLPH REINHOLD, of 7, Wellington Street, Woolwich, in the
County of Kent, 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 wheels of that class known as tension wheels and chiefly
designed for velocipedes.
In wheels of this class as heretofore constructed the spokes frequently break owing
to the fact that they are rigidly screwed into or attached to the hub.
The chief object of my invention is to obviate this breakage and to this end 1 attach
the spokes to the hub by loose connections so that any strain applied to the hub will
be equally divided between the spokes whereby no undue strain will be felt by any
one spoke.
In the accompanying drawing,
Figure 1 is an end view of a wheel hub adapted to have the spokes connected
thereto according to my invention, portions of some of the spokes being shown, and
Figure 2 is a side view of the same, partly in section.
Figures 3 and 4 are side and edge elevations respectively of a detail.
Figures 5 and 6 are views similar to Figures 3 and 4 respectively illustrating a
modification of the said invention, and,
Figures 7 and 8 are sectional views of details.
Figures 9, 10, 11 and 12 are views similar to Figures 1, 2, 3 and 4 respectively
illustrating a modification of my invention.
Similar letters of reference indicate corresponding parts in the several figures.
a is the wheel hub and b, b are the spokes. c, care nipples one of which is used in
conjunction with each spoke. As shown in Figures 1 to 4 cach nipple is formed
with an internally screw threaded socket d which is adapted to receive the end of a
spoke and with an eye e through which a pin f can be passed to secure it to the hub.
In order to apply the nipples to the hub I form circumferential slots or grooves g
in the peripheries of the flanges of the said hub, the said slots or grooves being at an
angle corresponding to a line extending from the centre of the wheel rim to the
centres of the flanges as shown in Figure 2. This angle, however, will vary according
to the diameter of the wheel to which my improvements are applied. Around the
flanges are formed holes h, h into which the pins or screws, which hold the nipples in
place can be passed.
In the modification of my invention shown in Figures 5 to 8 the nipple c is formed
in two parts the eye portion of which is adapted to screw into the socket portion. In
this case the opening through the socket is contracted at one end as shown in
Figure 8, and the spoke is provided with a head as shown in Figures 5 and 6 to
prevent it from slipping out of the socket. The socket is also provided with a nut to
enable the same to be turned to tighten the spoke.

page_text: In the modification of my invention shown in Figures 9 to 12 the nipples c instead
of being formed with eyes e are constructed with spherical heads and the recesses g, g
instead of being formed in the peripheries of the flanges are formed in the sides
thereof so as to afford seats for the heads of the nipples as shown in Figure 10. The
heads of the nipples have saw cuts k, k to enable the spokes to be tightened by means
of a screw driver or spoke tightener.
A wheel built on this plan gives direct and equal strain to each spoke, as the spokes
being hinged at the point where they receive their power give to every thrust of the
pedal keeping the strain of the spokes in a direct line, whereas in an ordinary wheel
every vibration is felt at the points where the spokes are screwed into the boss at
which points they usually get loose or break off.
A great advantage of my invention in addition to those before indicated is that if a
spoke accidentally breaks or becomes damaged it may be readily replaced without
injury to the hub:
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A tension wheel the spokes of which are attached to the hub by loose connections,
substantially in the manner, and for the purpose, specified.
2. In a tension wheel, the combination with the spokes of nipples which are pivoted
or jointed to the hub so that they can move relatively thereto, substantially, as
described.
3. The manufacture and use of a tension wheel the spokes of which are attached to
the hub substantially as hereinbefore described with reference to the accompanying
drawing.
