with which the joint is used; and
Fig. 10 is a section of the bar on the line 10-10 of Fig. 9.
In carrying out this invention, the usual handle bar is cut in two in the middle,
and each half is provided with an extension, 1, shaped at its outer portion to a ring 2,
having conical inner and outer surfaces. The handle bar stem, 3, of the machine, is
provided with a head, 4, having on either side a conical socket, 5, each of these
sockets being shaped and adapted to receive one of the conical rings 2. The head 4
has, at its centre, a hole of square or other irregular shape, through which passes a
bolt, 6, of contour similar to the hole, so that it will not turn therein, and having a
conical shaped head, 7, of such a size as to fit the interior of one of the rings 2.
A conical shaped nut, 8, is provided of a size suited to fit the interior of the rings 2,
and having a central opening of the same shape as the bolt 6, and adapted to receive
the same. The bolt is screw threaded, and is provided with a thumb nut 9,
which, when screwed up, binds the several parts together in the relation shown in
Fig. 3.
It will be observed that, inasmuch as the bolt 6 is irregular in outline, it cannot
turn in the head 4, and the nut 8 is also prevented from turning by its engagement
with the bolt. Consequently, the only parts free to move in adjusting the handle
bars are the rings 2, and as these are held between conical faces, a slight pressure
brought to bear by means of the thumb-nut, causes a very great amount of friction
upon the rings 2, and the latter are held very firmly in their position, while at
the same time it is possible to move them for the purpose of adjustment, by the
sudden application of considerable force.
The extensions 1 are shown extending from rods, 11, of metal. When it is
desired to make these extensions from wooden arms or bars, the extension 1 is
provided with a socket, 15, to receive the wooden bar or rod 12. This socket and
bar are shown in section in Fig. 7, the bar being forced home into the socket.
Fig. 9 shows a section of the two, partially detached from each other, and Fig. 8
represents a nut for holding the two together, which will presently be described,

page_text: The end of the bar 12 is made with two slots 13, 14, at right angles to each other,
and slightly tapering. The socket 15 is provided with a nut, 16, of the shape
shown, screw-threaded on its inner face, its sides tapering down until they are quite
thin. When the bar is inserted, its tapering end enters the interior of the nut 16,
and one of the slots receives a pin, 17, fixed in the socket. This pin is for the
purpose of preventing the bar from turning in the socket. Preferably, though not
necessarily, the exterior of the bar 12 is threaded at its extremity to fit the threads
in the interior of the nut 16. The bar having been inserted until its tapering end
enters the nut, the nut is turned until its screw-threads, engaging with the screw-
threads upon the bar (or cutting screw threads in the bar), draw the latter into
the position shown in Fig. 7.
The handle bars may be given any desired position on the bicycle, the range being
indicated in dotted lines in Fig. 1.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
from abroad by my foreign correspondents, I declare that what I claim is :-
1. As a means for attaching bicycle handle bars to the bicycle, extensions from
each bar, each extension being provided with an exterior and an interior conical
bearing surface, two recesses provided in the head, each recess having a conical
bearing surface to engage with the exterior conical surface of one of the extensions,
a bolt having a head with a conical bearing surface adapted to engage with the
interior conical bearing surface of one of the extensions, a washer having a conical
bearing surface adapted to engage with the interior conical bearing surface of
the other extension, and a nut for binding the parts together, substantially as
described.
2. The combination of two bicycle handle bars, an extension from each bar, each
extension being provided with an exterior and an interior conical bearing surface, a
head provided with two recesses, each recess having a conical bearing surface to
engage with the exterior conical surface of one of the extensions, a bolt having a
head with a conical bearing surface adapted to engage with the interior conical
bearing surface of one of the extensions, a washer having a conical bearing surface
adapted to engage with the interior conical bearing surface of the other extension, a
nut for clamping the parts together, and means for preventing the rotation of the bolt,
substantially as set forth.
3. The combination of two bicycle handle bars, each having an extension provided
with interior and exterior conical surfaces, a head provided with two recesses, each
having a conical surface adapted to engage with the exterior conical surface of one
of the extensions, a bolt having a conical surface adapted to engage with the interior
conical surface of one of the extensions, a washer having a conical surface adapted to
engage with the interior conical surface of the other extension, a nut for clamping the
parts together, and a web, as 7, having a hole through the same of irregular shape,
for the bolt, the bolt being also of irregular shape, to prevent rotation thereof,
substantially as set forth.
4. The joint for bicycle handle bars consisting of the head 4, the rings 2, the bolt 6,
and the nuts 8 and 9, substantially as described.
5. The means for attaching the rod or bar 12 to the joint, consisting of the
socket 15, and the interiorly screw-threaded nut 16, acting upon the tapering end of
the bar, substantially as described.
6. In combination with the socket 15, nut 16, and bar 12 (having slots in
the end thereof), the pin 17, to prevent the bar from turning, substantially as
described.
