PROVISIONAL SPECIFICATION.
A New or Improved Means for Adjusting the Ball Head, Handle Bar,
and Seat Pillar of Velocipedes.
I, HARRY PARSONS, of Ferndale, Wren Street, Coventry, in the County of
Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to an improved means for adjusting the ball head and
also the height.of the handle bar of velocipedes.
Heretofore the split clip used for adjusting the ball head and the handle bar
has been necessarily made in two parts, the one part forming the ball race
requiring to be hardened whereas the other part or clip proper requires to be left
soft so as to allow of the lugs formed thereon being drawn together. This form
of clip has also many disadvantages in practice. Now according to the present
invention these various drawbacks have been overcome and the ball race may be
made in one with the clip portion or collar so that the whole device may be made.
at one stamping and entirely hardened.
According to this invention instead of splitting the thickened portion of the
adjustable collar as usual so as to make the two lugs which are drawn together
by means of a bolt I form a transverse hole or a recess from either side. in which.
two cheeks are adapted to slide. The said hole or recesses are in such a position
and the cheeks of such a form as to allow them to engage with the handle bar
pillar and when drawn towards each other, by means of a right and left hand
threaded bolt passing through them or an equivalent device, to firmly clamp or.
hold the said handle bar pillar.
It will be readily seen that this device is equally applicable for adjusting the
height of the saddle pillar.

in and by the following statement:-
-
This invention relates to an improved device for locking the adjustment of the
steering head and also of the height of the handle bars and seat pillars of
velocipedes.
Heretofore the split clip used for adjusting the ball head and the handle bar
has been necessarily made in two parts, the one part forming the ball race
requiring to be hardened whereas the other part or clip proper requires to be left
soft so as to allow of the lugs formed thereon being drawn together. This form of
clip has also many disadvantages in practice. Now according to the present inven-
tion these various drawbacks have been overcome and the ball race may be made
in one with the clip portion or collar so that the whole device may be made at
one stamping and entirely hardened.

In the accompanying drawing which illustrates this invention applied by way
of example to the adjusting cone of the ball steering head:-
Figure is a broken view in side elevation, and
Figure 2 is a view in transverse section on line x x Figure 1.
In both views similar parts are marked with like letters of reference.
According to this invention the clip A has a projection or enlargement a on one
side through which is a transverse hole or a recess a¹ in which suitably shaped
blocks B, B, slide. The transverse hole or recess a¹ is in such a position with
respect to the vertical hole a2 through which the steering pillar passes that the
blocks B, B, engage with it when they are drawn towards each other which is
effected by means of a screw C having both right and left hand threads as shown
in Figure 2 of the accompanying drawing.
It will be seen that by this construction the collar A can be clamped to the
steering pillar so as to become firmly fixed thereto by so turning the screw Cas
to cause the blocks B, B, to move towards one another and that the said collar
can be released from the said pillar by turning the screw in the reverse direction
which causes the blocks B, B, to move away from one another.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
olaim is:
(1) The improved clip for fixing the adjustable parts of velocipedes, substan-
tially as set forth.
(2) For velocipedes an improved clip, consisting of a body part A having a
transverse hole cutting partially through the main hole or eye of the clip, of a pair
of shaped blocks B, B, sliding, in the said hole, and having longitudinal holes
through them, the hole in one of the blocks having a right hand screw thread
and the other a left hand screw thread, and of a right and left handed screw C
engaging with the blocks B, B, as and for the purpose set forth.
