Velocipedes".
I, OLAF PIHLFELDT, of 29 Golden Hillock Road, Small Heath, in the City of
Birmingham, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates principally to detail improvements in, or in the manu-
facture of certain parts of cycles, such as ball heads and junction lugs, and per-
tains in the first part, to the formation of the ends of the sleeves or outer tubes of
ball heads; in the second part, to the formation of junction lugs for ball heads and
other parts of cycles, and in the third part, to the splitting of the upper end of the
ball head inner tubes.
In carrying out the first part of my invention, the sleeve of the head is made
from a length of thin solid-drawn tubing, and the upper and lower ends are
expanded into annular cupped or flared entrances, of a diameter larger than that
of the tube itself, and adapted to receive the usual ball-bearing raced rings, which
are dropped or fitted within the said enlarged ends and surround the inner tube
down which the steering post passes.
In carrying out the second part of my improvements, the lugs, which form upper
and lower terminals to the sleeve and sockets for receiving the ends of the tubular
frame members, are pressed or formed from a blank of sheet steel in manner
following:-
A sheet steel blank is taken, the middle part of which is subsequently cupped
and drawn down into a hat-shaped well or sinking which forms the socket part of
the lug when the bottom is removed, whilst the ends of the blank, which are
rectangular in shape, formn languet-like straps which wrap around or circum-
ferentially embrace the sleeve of the ball head with their ends abutting. The lugs
thus pressed from sheet steel have their joints brazed at the same time that they
themselves are brazed to the sleeve immediately adjacent to the expanded ends.
In carrying out the third part of my improvements, the upper part of the inner
tube, immediately below the wormed end, is cross slit to an extent about one half
its diameter and also longitudinally slit downwards from the terminations of the
cross slit, thus forming a tongue out of the walls of the said inner tube, over the
split part of which a split lug is slipped and kept from rising by a nut above it
taking upon the extreme screwed end of the tube. When the lug is closed by a
cross pin taking through eyed ends of the same, the tongue is forced inwards upon
the outer surface of the steering post passing down the said inner tube and which

page_text: is thereby held in its adjusted position, leaving its wormed end intact or
uninfluenced by the closing of the lug, so that no slipping of the nut over the threads
can occur after the vertical adjustment of the steering post.
It will be understood that the application of the second part of my invention to
the production of seat pillar and like junction lugs, clips or sockets differs in no
essential respect from its application to a ball head junction lug as described.

I, OLAF PIHLFELDT, of 29 Golden Hillock Road, Small Heath, in the City of
Birmingham, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-

the ball head inner tubes.

In carrying out the-other-part-of my improvements, the upper part of the inner
tube, immediately below the wormed end, is cross slit to an extent about one half
its diameter and also longitudinally slit downwards from the terminations of the
cross slit, thus forming a tongue out of the walls of the said inner tube, over the
split part of which a split lug is slipped and kept from rising by a nut above
it taking upon the extreme screwed end of the tube. When the lug is closed
by a cross pin taking through eyed ends of the same, the tongue is forced
inwards upon the outer surface of the steering post passing down the said inner
tube and which is thereby held in its adjusted position, leaving its wormed end

page_text: intact or uninfluenced by the closing of the lug so that no slipping of the nut
over the threads can occur after the vertical adjustinent of the steering post.

a cycle ball head fitted with its steering pillar, and having the inner tube split and
eonstrueted-and-provided-with-improvements in accordance with my invention.

page_text: Improvements in and in the Manufacture of Parts of Velocipedes.
I, Olaf PihlFELDT, of 29 Golden Hillock Road, Small Heath, in the City of
Birmingham, Engineer, 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 principally to detail improvements in the ball heads of
cycles, and pertains in the one part, to the formation of the ends of the sleeves or
outer tubes of ball heads, and in another part, to the splitting of the upper end of
the ball head inner tubes.
In carrying out the one part of my invention, the sleeve of the head is made
from a length of thin solid-drawn tubing, and the upper and lower ends are
expanded into annular cupped or flared entrances, of a diameter larger than that
of the tube itself, and adapted to receive the usual ball-bearing raced rings, which
are dropped or fitted within the said enlarged ends and surround the inner tube
down which the steering post passes.
The lugs, which form upper and lower terminals to the sleeve, and the sockets
for receiving the ends of the tubular frame members may be pressed or formed
from a blank of sheet steel in manner following:-
A sheet steel blank is taken, the middle part of which is subsequently cupped
and drawn down into a hat-shaped well or sinking which forms the socket part of
the lug when the bottom is removed, whilst the ends of the blank which are
rectangular in shape, form languet-like straps which wrap around or circum-
ferentially embrace the sleeve of the ball head, with their ends abutting. The lugs
thus pressed from sheet steel have their joints brazed at the same time that
they themselves are brazed to the sleeve immediately adjacent to the expanded
ends.
In carrying out the other part of my improvements, the upper part of the inner
tube, immediately below the wormed end, is cross slit to an extent about one half
its diameter and also longitudinally slit downwards from the terminations of the
cross slit, thus forming a tongue out of the walls of the said inner tube, over the
split part of which a split lug is slipped and kept from rising by a nut above
it taking upon the extreme screwed end of the tube. When the lug is closed by a
cross pin taking through eyed ends of the same, the tongue-is forced inwards upon
the outer surface of the steering post passing down the said inner tube and which
is thereby held in its adjusted position, leaving its. wormed end intact
uninfluenced by the closing of the lug so that no slipping of the nut over the
threads can occur after the vertical adjustment of the steering post.

said inner tube receiving the locking ring nut.

and set forth.
Thirdly. In the ball heads of cycles, forming the tongue, through which the
clamping or binding of the inner tube to the stem of the handle bars is effected, by
piercing the same out of the metal of the upper part of the said inner tube, inwards.
