Improvements in or connected with the Arrangement or Construction
of Handle Bars for Velocipedes and other Vehicles, and in Pumps
carried thereby.
I, GEORGE SINGER, Managing Director Singer Cycle Co. Limited, Singer
Cycle Works, Coventry, in the County of Warwick, do hereby declare the nature
of this invention to be as follows:-
The object of my invention is to so construct and arrange the handle bar of
bicycles or other velocipedes, and also the pump for inflating the tyres of same,
whereby the pump may be carried within the frame-work of the handle bar, in
such a manner as to be readily removed 'when desired.
According to my invention I employ a handle bar, generally having a vertical
pillar, to which is secured a straight horizontal tube, extending an equal distance
upon each side of the vertical pillar. At each end of the horizontal tube there
extends rearwardly two tubular supports, upon which the handles are affixed.
The straight horizontal tube is arranged so that there is a free and unobstructed
passage from one end thereof to the other; one end is closed, the opposite end
being open and internally screw threaded.
The pump is, or may be, of any ordinary type, and provided with the usual
flexible tube for connecting the pump to the tyre valve. The handle or rear end
of the pump is constructed with a head or collar, forward of which is a screw
thread cut upon a cylindrical part, of larger diameter than the pump handle
proper. The screw thread is of such a size as to take into the internal thread
within the end of the horizontal tube.
When it is desired to place the pump into position for carrying same, it is
slidden into the horizontal tube, and screwed into same, until the forward end of
the head or collar on the pump handle, bears against the extremity of the screwed
end of the horizontal tube.
I sometimes use a loose cap screwing into the end of the handle bar, or a cap
arranged to fit in the end of the handle bar and held by a stud fitting into a slot in
the end of the tube, the cap being turned partly round to fix or release it. In
this case I introduce a spiral spring pressing against the pump in order to pre-
vent rattle of the pump within the tube.
The pump proper is of a shorter length than the horizontal tube and generally
has the flexible tube attached in position thereon. This flexible tube, or at any
rate, the extreme end part thereof, should bear against the closed end of the
horizontal tube, so that when the pump is in position, the flexible tube will then
be in compression, whereby all rattling of the same within the handle bar is
prevented.

I, GEORGE SINGER, Managing Director Singer Cycle Co. Limited, of Singer
Cycle Works, Coventry, in the County of Warwick, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
The object of my invention is to so construct and arrange the handle bars of
bicycles or other velocipedes, and also the air pump for inflating the pneumatic
tyres of same, all as hereafter described, whereby the pump may be carried
within the framework of the handle bar, in such manner as to be readily removed
when desired, and at the same time to be so held that it is prevented from rattling
within the tube in which it is placed.
I will now proceed to describe my invention with reference to the accompanying
drawings whereon:
Fig. 1 is a plan of the pump detached from the handle bar.
Fig. 2 is a sectional plan of the handle bar with the pump removed therefrom.
Fig. 3 is a sectional plan of the handle bar with the pump in position.
Figs. 4 and 5 shew modifications of my invention shewing equivalent means
of securing the pump in position.
According to my invention I employ a handle bar generally having a vertical
pillar A, to which I secure a straight horizontal tube B, extending an equal
listance upon each side of the vertical pillar A. At each end of the horizontal
tube B, there extends rearwardly, and usually at an angle in both a horizontal
and vertical plane (to suit the views of the rider) two tubular supports C and D,
upon which the handles E are affixed in the usual manner.
The straight tube B is arranged so that there is a free and unobstructed massage
from one end thereof to the other end, one end being closed by suitable means
(such as by a cap screwed into the tube,) brazing, or otherwise permanently fixing
a cap F which is or may be provided with a countersunk internal face G the
other end of the handle bar being open and formed with internal screw threads H.
The pump
I Fig. 1 is or may be of any ordinary type and be provided with the
usual flexible tube I for connecting the said pump to the tyre valve.
The handle portion M or rear end of the pump is constructed with a head or
collar K, forwards of which is a screw thread L cut upon a cylindrical part which
is of larger diameter than the pump handle M. This screw thread L is made to
fit in the internal screw thread H of the handle bar tube B.
When it is desired to place the pump into position for carrying same, it is
slidden into the horizontal tube B and screwed into same by the screw threads L
and H, until the head K on the pump handle fl, bears against the extremity of
the horizontal tube B.
The total length of the pump I is greater than the horizontal tube B, that is
when it has the flexible tube 12 attached in position thereon.
When the pump is inserted into the handle bar tube, I have found it desirable
that the end of the flexible tube I, should bear against the closed end of the
handle bar, or as shewn in the drawing Fig. 3 it should bear against the counter-
sunk end of the plug F and this should take place before the head K of the
handle M has come in contact with the end of the tube B so that on screwing
the pump home the flexible tube 18 will be in compression as shewn at Fig. 3,

page_text: whereby all rattling of the pump or of parts thereof within the handle bar is
prevented.
Instead of the above arrangement in which the screw L is cut in the pump
handle M I may form this screw L on a separate plug N (as shewn in Fig. 4) in
which case the handle M of the pump may be of the same diameter throughout
its length. In this arrangement I attach a spiral spring 0 to the inner end of
the plug N for the purpose of keeping the pump in a fixed position and insuring
that the flexible tube Is is in contact with the closed end of the tube, or with
the countersunk end of the plug F.
Instead of the plug N being screwed in the tube B by screw threads L and H,
I sometimes use the arrangement shewn in Fig. 5 in which case I cut a slot P in
the end of the tube B and the plug N is provided with a pin R which on being
forced into the slot and then turned secures the plug H in position.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed. I declare that what I
claim as my improvements in or connected with the arrangement or construction
of handle bars, for velocipedes and other vehicles and in pumps carried thereby
to be as follows:-
1. A handle bar composed of a horizontally extending straight tubular part,
a stem at right angles thereto, and branches from such straight horizontal part
to carry the handles, in combination with a pump adapted to be inserted within
the straight tubular part, and means (such as screw threads, pin and alot, or
equivalents) whereby the pump may be detachably secured in position within the
horizontal straight tubular vart of the handle bar, substantially as set forth.
2. A handle bar, composed of a horizontally extending straight tubular part,
a stem at right angles thereto and branches to carry the handles, in combination
with a pump adapted to be inserted within the straight tubular part, a screw
thread on or near the outer end of the pump, and a screw thread within the
tubular straight part with which the screw of the pump engages and whereby
the pump is detachably secured in the bar substantially as described.
3. The arrangement and construction of tubular handle bar, in combination
with a pump carried therein, and means for detachably securing and fixing the
pump in position, substantially as and for the purposes described with reference
to Figs. 1 to 5 of the accompanying drawings.
