Improvements in or relating to Cycles and the like.
We, JOHN WILLIAM HOLLAND, of 10, Sparsholt Road, Crouch End, in the County
of Middlesex, Engineer, and ARTHUR ANTHONY, of Hawthorn Villas, Jeffcock Road,
Wolverhampton, in the County of Stafford, Cycle Maker, 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 cycles and the like, its object being the construction of
improved details such as the handle-bar stem, seat-pillar, and hubs hereinafter
described by way of example.
In the accompanying drawings
Figure 1 a front elevation of a handle-bar stem according to this invention;
Figure 2 is a view of a steering-head, partly in elevation and partly in vertical
central section, the figure being shown to facilitate comprehension of the means
by which the improved handle-bar stem illustrated in Figure 1 is held in position
in the machine.
Figure 3 is a front elevation of an improved seat-pillar and devices for adjusting
the same:
Figure 4 is a vertical central section on the line 4-4 and Figure 5 a transverse
section on the line 5-5 of Figure 3.
Figure 6 is a view half in elevation, and half in section in the plane of the axis
of rotation, of an improved back hub especially advantageous for use with an
improved frame of the kind hereinafter referred to:
Figure 7 is a side elevation of the same.
With reference first to Figure 1 A is the handle bar, the stem of which consists
of two tubes A¹, of D section or approximately semi-cylindrical, with a space A
between them. This divided stem is passed down through the rings B and B of the
steering-head (Figure 2). so that a bolt C with a coned end adjustable on the
diametral line of the head by means of a nut C2 occupies the space A³; by adjusting
the nut to draw the coned portion of the bolt C in between the two tubular
parts A¹ of the stem A3, these latter are forced outwards to engage firmly with the
bore of the interior of the rings B and B, which in any desired manner are con-
nected with the leading-wheel fork; for instance their connection with the fork
can be effected in the manner described with reference to Figures 16 and 17 of
the drawings appended to the Specification of Letters Patent No. 20999 of 1896
granted to us.
Figures 3, 4, and 5, show a somewhat similar arrangement applied to the seat-
pillar, the stem of which is constituted by twin tubes A' of D section, entering
the down tube D, which at its upper end has fixed to it a strengthening ring E,
through which passes a bolt C coned or tapered at C, so that when moved endwise
by a nut C upon it the coned portions Ci will force the D-section tubes A¹ out-
wards to bind securely against the inside of the down tube D at the height at
which the pillar has been adjusted.

page_text: It is to be clearly understood that it is not essential to employ the coned bolt
as a means for forcing the tubes A¹ apart from each other, inasmuch as any
desired device may be adopted for thrusting apart the two members A¹ of which
the divided stem is composed; moreover these latter are not of necessity tubular,
nor need they be D-shaped in section.
With reference now to Figures 6 and 7 it will be seen that the ends F¹ of the
improved hub F in the example illustrated are carried by ball bearings G, or
other bearings, placed eccentrically in circular sheaves H; the latter are rotatable
about their own centres in straps J J¹ secured to the frame of the machine at the
rearmost angle, as indicated in Fig. 7. In the example illustrated, the bottom
strap is attached to the top one by a pair of screws K K¹ to enable the lower strap
to be moved to facilitate adjustment of the bearings by rotation of the sheaves H
within the straps J J¹, for instance to enable the distance between the centre of
the rear hub and that of the crank axle to be varied in a manner well understood.
But the movable strap may be retained in place by other means than the two
screws shown there might for example be a hinge in the place of the screw K.
arranged horizontally, so that by removing the screw K¹ the bottom strap J¹
could be lowered downward about the hinge, in a vertical plane.
In Figure 7 the improved hub is illustrated as applied to the rear-wheel bearing
in a web-frame, that is to say a frame in which the space between the tubular
members such as L M is filled in by a web N; it is desirable to be able to avoid
the necessity for forming any slots in this web such as would be needed if a driv-
ing chain were passed in the ordinary manner from a chain-wheel placed between
companion webs such as N which form opposite sides of the cycle frame. to the
usual chain wheel on the end of the crank shaft exterior to the frame. The con-
struction of the improved! hub enables the chain to be put entirely outside the
frame, so that slotting of the latter is avoided, for it is provided with an exten-
sion 2 passing through the ball-bearings in one of the eccentric sheaves H to the
outer side of the same, at which the chain wheel F3 is secured upon it. Thus
the chain and chain wheels are kept entirely outside of the frame, which, for the
reasons before stated is a great advantage in web-frame machines, and is con-
venient in other machines.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In a steering head for a cycle or other vehicle the combination with a wedging
device or a ring carrying a coned bolt such as C of a handle bar or seat-pillar with
divided stem substantially as described.
2. In a cycle or other vehicle the combination with a hub of an extension such
as F projecting therefrom to the exterior of one of the bearings to carry a gear
wheel for the purpose described.
3. In a cycle or other vehicle the combination with a hub such as F and bear-
ings such as H in which it rotates of an extension such as Fa projecting from the
hub to the exterior of one of the bearings to carry a gear wheel for the purpose
described.
4. In a cycle or other vehicle a divided support such as J J¹ for the axle-bearing
substantially as described and illustrated in Figure 7 of the accompanying
drawings.
5. In a cycle or other vehicle a divided support such as J J¹ for the axle-bearing
the parts of which are hinged together substantially as and for the purpose
described.
6. In a cycle or other vehicle the combination and arrangement of parts con
stituting the seat-pillar holding device substantially as and for the purpose
described and illustrated in Figures 3, 4 and 5 of the accompanying drawings.

page_text: 7. In a cycle or other vehicle the hub substantially as described and illustrated
in Figure 6 of the accompanying drawings.
8. In a cycle or other vehicle the hub and bearing substantially as described and
illustrated in Figure 6 of the accompanying drawings.
