PROVISIONAL SPECIFICATION.
Improvements in Handle Bar Attachments for Cycles.
I, MARTIN DIEDERICH RUCKER, of 32 Holborn Viaduct in the County of
London, Managing Director of Humber & Co. Ltd., do hereby declare the nature
of this invention to be as follows:-
This invention relates to handle-bar attachments for cycles, particularly for the
back riders of tandem or multiple machines, though it may also be employed for
the front riders of multiple machines and single machines.
I will first describe the invention as applied to the back seat of a tandem
bicycle. In this case the top horizontal tube of the frame is enlarged to provide
a boss or socket through which the stem of the handle bar passes being fixed
therein by a taper or other cotter adapted when screwed up to grip the stem of the
handle bar. The stem itself is very short, practically only about long enough to
pass through the before mentioned socket and is split and provided with lugs and
bolt for tightening them up so that it may fit around the handed bar which when
the bolt is slackened can be turned in the head of the stem.
With this arrange-
ment four different positions of the handles can be obtained if the bar be bent.
In one position the stem is placed through the socket from above and the handle
bar being turned with the handles upward the handles will stand according to the
amount of the bend higher than that portion of the handle-bar which turns in the
stem. Second, the bandle bar may be turned round in the stem so that the handles
are nearly the level of the bar, thus giving another position varying according to
the amount of the bend in the handle bar, from the previous one. Third, the stem
can be inserted from underneath the socket thus placing the central portion of the
handle bar lower than in the two previous cases, and the handles can still be
adjusted up or down as previously described.
The same handle bar may be applied to the front or steering head of a cycle
preferably with a longer stem than previously described, and in this case the two
first described positions only can be obtained. In all cases the tilt of the handles
themselves can be altered by turning the:handle bar in its stem, while by slackening
the stem in its socket the whole handle bar can be turned into the axial line of the
machine so.as to reduce the width.

Improvements in Handle Bar Attachments for Cycles.
I, MARTIN DIEDERICH RUCKER of 32 Holborn Viaduct in the County of
London, Managing Director of Humber and Company Limited, 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 handle-bar attachments for cycles, particularly for the
back riders of tandem or multiple machines, though it may also be employed for
the-front riders of multiple machines and single machines.

page_text: I will first describe the invention as applied to the back seat of a tandem
bicycle. In this case the top horizontal tube of the frame is enlarged to provide
a boss or socket through which the stem of the handle bar passes being fixed
therein by a taper or other cotter adapted when screwed up to grip the stem of the
handle bar. The stem itself is very short, practically only about long enough to
pass through the before mentioned socket and at the end opposite to that fitting in
the socket is split and provided with lugs and bolt for tightening them up so that
it may fit around the handle bar which when the bolt is slackened can be turned in
the head of the stem. With this arrangement four different positions of the
handles can be obtained if the bar be bent. In one position the stem is placed
through the socket from above and the handle bar being turned with the handles
upward the handles will stand according to the amount of the bend higher than
that portion of the handle-bar which turns in the stem. Second, the handle bar
may be turned round in the stem so that the handles are nearly the level of the
bar, thus giving another position varying according to the amount of the bend in
the handle bar, from the previous one. Third, the stem can be inserted from
underneath the socket thus placing the central portion of the handle bar lower
than in the two previous cases, and the handles can still be adjusted up or down
as previously described.
In the accompanying drawings,
Figures 1, 2 and 3 are perspective views of portion of a multiple machine
showing the same handle bar attachment in many of its possible positions of
adjustment and not in connection with the steering head and Figures 4 and 5 are
perspective views showing two different ways of applying my invention to the
steering head of a cycle.
Like letters indicate like parts throughout the drawings.
I will first describe my invention as adapted to the requirements of the back
rider of a tandem bicycle. In this arrangement the top horizontal tube A of the
frame is enlarged to provide a boss or socket A' through which the stem C of the
handle bar D passes. This socket A' may be close behind the lug or boss A³ in
which the L-pin E of the front saddle E' is adjustably secured as for example, by
means of a taper or other cotter E 2 operated by a nut E 3 thereon. The handle
stem C may be fixed in any desired position in the socket A¹ by a taper or other
cotter F adapted, when tightened or screwed up by the nut to grip the stem C.
The stem C is very short, practically only about long enough to pass through the
socket A as shown in the drawings, and at the end opposite that which fits in the
socket A, viz. the upper end in Figures 1 and 2 and the lower end in Figure 3, it
is provided with a split socket C¹ having lugs C2 with which engages a bolt C 3
whereby the split socket C2 may be tightened upon the handle bar D passing
through said socket.
When the nut F1 is slackened and the handle stem C consequently released, the
handle bar D may be turned in a horizontal or approximately horizontal plane into
any desired position for example it may be turned so as to be more or less in line
with the machine frame and thereby cause the machine to take up less room than
it otherwise would do. When the bolt C 3 is slackened the handle bar D may be
turned in the split socket so as to raise or lower the handles D1 D2 to any desired
extent these being secured in their adjusted position by tightening the bolt C 3.
With this arrangement many different positions of the handles D' D 2 can be
obtained, if, as shown in the drawings, the handle bar D is bent; for example, the
stem C may be fitted into the socket A' from above, with the handle D' at the
right-hand and the handle D 2 at the left hand side of the machine say as shown
in full lines in Figure 1. While the stem C is retained in this position the bolt.C 2
may be slackened and the handle bar D and handles D' D 2 turned into: many
different positions, one of which is indicated in dotted lines in Figure 1. After
slackening the nut F' and cotter F the stem C may be removed from the socket A',
the handle bar D turned end for end, and the stem C replaced in the socket A¹ and
secured therein; the handle D' will then be at the left hand and the handle D2 at
1

page_text: the right hand side of the machine as shown in full lines in Figure 2, these handles
while still retaining this general position in relation to the machine, being adjustable
in the same manner as described with reference to Figure 1, one of their positions
of adjustment as an example being shown in dotted lines in Figure 2. Instead of
inserting the handle-bar stem C into the socket A¹ from the upper side as shown
in Figures 1 and 2 it may be inserted from the underside as shown in Figure 3
with the handle D' or D2 at either side of the machine, in which position it is
susceptible of all the adjustments previously described with reference to Figures 1
and 2 as will be well understood without further description.
In applying my invention to the steering head of a cycle I form the before
described socket A' upon, or rigidly connect it to the steering post G, and
projecting either to the front of the steering post, or, as shown in Figure 4 to the
rear of it. Or I may as shown in Figure 5 form the socket A' on the stem C and
fix this in any desired position on the steering post G by tightening the cotter F
as before described with reference to Figures 1 to 4. Each of these arrange-
ments is capable of being adjusted to the same extent as that before described with
reference to Figures 1, 2 and 3.
I
Instead of providing the socket A' in the frame as shown in Figures 1, 2 and 3,
may
form this socket in or upon the handle-bar stem C in the manner shown
for example in Figure 5, and provide projections on the frame to fit into this
socket.
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. The combination with a cycle of a handle bar capable of being adjusted
independently of the frame in substantially the manner described.
2. The combination with a cycle handle bar of a stem having two split sockets
such as CA one for securing the handle bar and stem together and the other for
securing the handle bar to the cycle frame or steering post substantially as described
and illustrated in the accompanying drawings.
3. The combination with a cycle frame having a socket such as A¹ of a handle-
bar and handle-bar stem adjustably secured together and the stem of which is
capable of being inserted into either end of the socket substantially as described
and illustrated in the accompanying drawings..
4. The combination with a cycle steering post having a socket such as A' of a
handle bar and handle-bar-stem adjustably secured together the stem of which is
capable of being inserted into one or either of the two ends of the socket substan-
tially as described.
5. The complete handle bar attachment substantially as described and illustrated
in Figures 1, 2 and 3, or in Figure 4 or Figure 5 of the accompanying drawings.
