Improvements in or connected with Handle Bars for Cycles
and the like.
We, GUSTAVO DONAT, of 3, 4, Australian Avenue, London, E.C., Warehouseman,
and ARTHUR SLADEN JONES, of 8, Colville Gardens, London, W., Gentleman, 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:-
|_ Our_invention-consists-in-improvements in or connected with the handles
mounted upon bicycles, tricycles, and similar machines, the particular object
we have in view being to enable the rider to regulate or adjust the same to a con-
venient height without dismounting, and to ensure rigidity in the fastening.
The way and manner in which we carry out our improvements will be under-
stood by reference to the drawing in which :-
Fig. 1, is a general perspective view.
Fig. 2, is a perspective view shewing disc.
Fig. 3, is a part transverse vertical section.
Fig. 4, is a side elevation part being in section shewing screwed cap or cover.
Fig. 5, is a modification partly in section.
Fig. 6, is a side elevation.
In the drawings 1, is the handle or handle bar, to the centre of this is secured
preferably by brazing or by equivalent means a disc 2. This is usually made of
steel, it may however be made of any suitable metal; this disc before being
secured to the bar is bored, turned, faced, and drilled, upon its periphery with a
series of holes 3. The cap or cover 4, is preferably a casting or stamping of
metal and is advantageously formed in one piece with the cylindrical portion 5,
which after being turned, bored out, and threaded as at 6, is forced into, brazed,
or otherwise made fast to the stem of the machine 5º.
The cap or cover 4, is bored out as at 7, so as to enable the handle bar 1, to pass
through, and is made to closely fit the disc 2, rigidity being secured by means of
a plate 8, the edge of which is screwed so as to engage with a corresponding
thread 6, cut in the interior of the cap 4, perforations 8ª, are made in this plate
to enable the same to be screwed up by a key, and to prevent its working loose it is
further secured by a set screw 6 see Fig. 4. Within the cylindrical portion of
the fitting is a spindle, preferably of steel, this is turned down so as to form a
shoulder 9 the upper part 9, passing through the base of the cover and being so
shaped as to engage with one or other of the holes 3, in the disc, this spindle is
forced upwards by the spring 10, which surrounds the shank 9b, and is regulated
by the screwed plug 11, which engages with the thread 6, formed in the end of
the fitting. An inclined slot 12, is formed in the wall of the casting and a lever 13,
the end of which is bent round as at 14, is pivoted by means of a set screw 15,
as shewn. The end of the arm 14, is drilled and connected to the shoulder of
spindle by stud 15", screwed therein.
The operation of our invention is as follows:-So long as the upper part of

page_text: the spindle 9, engages with one or other of the holes 3, in the disc, the handle
bar remains rigidly locked in any required position, if the rider however desires
to raise or lower the same he has only to press the lever 13, as see Fig. 4, which
forces the end of the spindle 9; out of engagement with the disc. The bar is then
adjusted and on the pressure being relaxed it is again locked by the reaction of
the spring 10.
Fig. 5, is a modification of our invention in which the disc is drilled or per-
forated upon its side in place of the periphery. In the drawing 2, is the disc,
the cover of which 4, is formed by preference in one piece with the cylindrical
portion 5, which; as is shown; is placed beneath the handle bar. The adjustment
is made by means of lever 13, which may be connected to stud 15 by means of a
knuckle joint 16. This stud passes through an inclined slot 12, formed in the
fitting. By forcing the lever upwards 'the end of the locking spindle 9, is disen-
gaged from the disc. The handle being reset is locked in any position by the
spring 10. The fitting is attached to the stem 5*, by means of the socket 5,
brazed, screwed, or similarly connected thereto.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. For the purpose of fastening and regulating or adjusting the handles of
bicycles, tricycles, and the like, the combination and use of a disc, drilled on its
periphery and secured to the handle bar, with a fitting, part of which containing
the adjustable spring and locking spindle passes within and is secured to the
tubular stem of the machine. The top of said fitting forming the attachment
to the handle by means of the cover or case surrounding and clamping the disc,
substantially as shewn."
2. For the purpose of securing, regulating, and adjusting, the handles of cycles
and the like the combination of the disc 2, drilled or recessed as at 3, and secured
to the handle. The cover 4, formed in one piece with the cylinder 5, containing
the locking spindle and spring and secured to the stem, the plate 8, screwed into
the cover as shewn; and locked by the set screw 6 for ensuring rigidity between
the handle and the stem. The adjustable spindle surrounded by spring 10, for
locking the disc, and the lever 13, pivoted at 15, and operating said spindle in
the way and manner and for the purposes described.
:
3. For the purpose of securing and adjusting the handles of cycles and the like
the modification shewn in Figs. 5, 6. The disc 2, drilled on the side and locked
by the adjustable spring spindle mounted in the cylinder at right angles to said
disc the respective parts cooperating for the purpose specified..
