Improvements in or Additions to Certain Tubular Parts of Cycle
Framings, and in Tools to be employed in connection with the
Production of the said Parts.
I, BARON ROSE, of the Firm of Rose Brothers, of Halesowen, in the County of
Worcester, Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention relates to those parts of cycle framings, in which the members
telescope each other, work within each other, or over each other for adjustment or
change of position, and my invention has for one of its objects, the prevention of
the said members from rotating, and for its other object, the manufacture or
production of the said non-rotating telescopic parts.
The said members or telescopic fitted parts, comprehend steering posts, adjustable
heads, saddle pillars, adjustable fork branches, adjustable handle bars, adjustable
brake rods, and other parts requiring to be adjusted, or having sliding movements
one upon another, or one within another.
Thus for example, the steering rod or steering post member has heretofore been
prevented from rctating within its socket, sleeve or hollow part, by a set pin or
band clip, adapted to act in common for both preventing rotation, and affixing the
adjustable members in any desired position.
The employment of set pins is objectionable, as the constant vibration attendant
upon riding gradually loosens the same, and eventually disconnects the parts, with
the result that the rider looses all control over his machine, as the motion of his
steering rod is independent or free of the post member.
By my invention, the tube-over-tube members are incapable of rotation, but
admit of a longitudinal sliding motion, whilst the set pin or clip as heretofore
referred to, is employed only to affix or lock the said telescopic members from
longitudinal change of position.
In carrying out one form of my invention in connection with a safety bicycle, I
provide the casing or sleeve of the steering post, or that part comprehending the head
of a machine, with an inwardly directed longitudinal rib, feather or sinking, which
takes into a like shaped longitudinal channel, groove, recess, or sinking directed down,
and formed within the outer side of the walls of the steering post or inner tube.
Thus, these tubular members, or tubular and socket members, have longitudinal
and coincident he and she grooves, with the rib formation of the one taking within
the recess formation in the other, on the one tube member being clipped over the
other tube member, of which the inside bore of the one is of the outside diameter
of the other, so that when in use, the steering rod member, which is terminated by
the steering handles, or handle bar, is incapable of rotation, other than in common
with the member within which it slides.
As a further form of my invention, the channel or longitudinal sinking, may be in
the socket, sleeve or case member, whilst the rib may be upon the steering post
member, or in other words, the converse of that previously described.
It will be understood that both outer and inner members have recesses alike and
coincident, and that the passing of the one over the other makes the one recess into
a rib and the other into a channel.
In carrying out the longitudinal channelling, recessing or furrowing, as described
in the first arrangement, I proceed as follows
I take a die with double coned leads, whose bore is of the outside diameter of an
operated upon tube, and mounted and fitted crosswise within the wall comprehending
the bore as aforesaid, is an anti-friction impressing tool, in the form of a roller,
having a tread or impressing part equal in breadth to the inside of the channel,

page_text: groove, or longitudinal depression to be formed, and extending within the mouth of
the bore to an extent equal to the depth of the said channel.
A bulb mandril forms the internal support for preventing the change of figure
of the tube under operation.
The bulb is longitudinally channelled to a breadth and depth equal to the rib
coming upon the inside of a member, and to the channel coming upon the outside
of a member, so that by passing a plain tube through the die, and over the bulbous
mandril, the same becomes longitudinally channelled upon the outside, and like
ribbed on the inside.
Or on the other hand, the converse may be produced by having a rib upon the
mandril, and a sinking within the walls of the die.
Or the mandril may carry a roller, wheel or stud, to correspond with a gap left
within the die, in the direction of drawing.
In lieu of a roller in the die, a stud or projection may be used.
If desired, each member may have two or more ribs or channels, which coinci-
dently fit and slide one with each other, in common with the longitudinal adjustment
of the members.
The application of my invention to the production of other tube-over-tube parts,
differs in no essential respect from its application to a steering post and its cognate
part or parts as herein described.

Improvements in or Additions to Certain Tubular Parts of Cycle
Framings, and in Tools to be employed in connection with the
Production of the said Parts.
I, BARON ROSE, of the Firm of Rose Brothers, of Halesowen in the County
of Worcester, Manufacturer, 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 those parts of cycle framings, in which the members
telescope each other, work within each other, or over each other for adjustment or
change of position, and my invention has for one of its objects, the prevention of
the said members from rotating, and for its other object, the manufacture
or production of the said non-rotating telescopic parts.
The said members or telescopic fitted parts comprehend steering posts, adjustable
heads, saddle pillars, adjustable fork branches, adjustable handle bars, adjustable
brake rods and other parts requiring to be adjusted, or having sliding movements
one upon another, or one within the other.
Thus, for example, the steering rod or steering post member has heretofore been
prevented from rotating within its socket, sleeve or hollow parts, by a set pin or
band clip, adapted to act in common for both preventing rotation, and affixing the
adjustable members in any desired position.
The employment of set pins is objectionable, as the constant vibration attendant
upon riding gradually loosens the same, and eventually disconnects the parts, with
the result that the rider looses all control over his machine, as the motion of his
steering rod is independent or free of the post member.
By my invention, the tube-over-tube members are incapable of rotation, but
admit of a longitudinal sliding motion, whilst the set pin or clip as heretofore
referred to, is employed only to affix or lock the said telescopic members from
longitudinal change of position.
In carrying out one form of my invention in connection with a safety bicycle, I

page_text: provide the casing or sleeve of the steering post, or that part comprehending the
head of a machine, with an inwardly directed longitudinal rib, feather or sinking,
which takes into a like shaped longitudinal channel, groove, recess, or sinking,
directed down, and formed within, the outer side of the walls of the steering post.
or inner tube.
Thus, these tubular members or tubular and socket members, have longitudinall
and coincident he and she grooves, with the rib formation of the one taking within
the recess formation in the other, on the one tube member being slipped over the
other tube member, of which the inside bore of the one is of the outside diameter
of the other, so that when in use, the steering rod member, which is terminated by
the steering handles, or handle bar, is incapable of rotation, other than in common
with the member within which it slides. or with which it is adjustable longi-
tudinally.
As a further form of my invention, the channel or longitudinal sinking, may be
in the socket, sleeve or case member, whilst the rib may be upon the steering post
member, or in other words, the converse of that previously described.
It will be understood that both outer and inner members have recesses alike,.
and coincident, and that the passing of the one over the other makes the one recess.
into a rib and the other into a channel.
In carrying out the longitudinal channelling, recessing or furrowing, as described
in the first arrangement, I proceed as follows:-
I take a die with double coned leads, whose bore is of the outside diameter of
an operated upon tube and mounted and fitted crosswise within the wall com-
prehending the bore as aforesaid, is an anti-friction impressing tool, in the form of
a roller, having a tread or impressing part equal in breadth to the inside of the
channel, groove, or longitudinal depression to be formed, and extending within the
mouth of the bore to an extent equal to the depth of the said channel.
A bulb mandril forms the internal support for preventing the change of figure
of the tube under operation.
The bulb is longitudinally channelled, to a breadth and depth equal to the rib
coming upon the inside of a member, and to the channel coming upon the outside
of a member, so that by passing a plain tube through the die, and over the bulbous
mandril, the same becomes longitudinally channelled upon the outside, and like
ribbed on the inside.
Or on the other hand, the converse may be produced by having a rib upon the
mandril, and a sinking within the walls of the die.
Or the mandril may carry a roller, wheel or stud, to correspond with a gap left.
within the die, in the direction of drawing.
In lieu of a roller in the die, a stud or projection may be used.
If desired, each member may have two or more ribs or channels which
coincidentally fit and slide one with each other, in common with the longitudinal
adjustment of the members.
The application of my invention to the production of other tube-over-tube parts,
differs in no essential respect from its application to a steering post and its cognate
part or parts, as herein described.
Figure 1 of the accompanying drawings represents partly in section, and partly
in elevation, a cycle head or post made up of, or fitted with, telescoping and keyed
members or tube-over-tube members capable of sliding longitudinally, but
incapable of rotation, consequent upon an inside rib of the one member taking
within an outside channel of the other member.
Figure 2 represents, upon an enlarged scale, a longitudinal vertical section of the
upper part of the said cycle head or post as in Figure 1.
Figure shows a back elevation of Figure 2, showing the channels within the
said telescoping or tube-over-tube members, and how the inner side wall of
the channel of the outer member forms the rib for taking the coincident channel
impressed or sunken longitudinally within the outer side of the wall of the inner
tubular member.

page_text: Figure 4 represents a transverse section upon the dotted lines A B Figure 2.
Figure 5 is a cross section upon the dotted lines C D of the said Figure 2.
Figure 6 is a section of the outer telescoping tubular member.
Figure 7 is a transverse section on the dotted lines E F Figure 6.
Figure 8 represents a longitudinal section of the inner tolescopic member, with a
longitudinal channel impressed upon one side.
Figure 9 is a transverse section of the same upon the dotted lines G H Figure 8.
Figure 10 represents a modified form of my invention. In this arrangement, the
channels are impressed upon the inner walls and the ribs or longitudinal indents
formed thereby bulged outwardly.
Figure 11 represents a cross section upon the dotted lines I J Figure 10.
Figure 12 represents telescopic members or tube-over-tube members provided
with four longitudinal channels and ribs, with the one taking into the other, or the
one taking over the other.
a is an outer tubular member, and an inner tubular member. The outer
tubular member a has an inwardly directed longitudinal rib, feather or sinking a²,
which takes into a coincident and like-shaped longitudinal channel or sinking ³, in
the other member /.
Thus the said telescoping tubular members, or the tube-over-tube members,
having longitudinal and coincident he and she grooves a², 62, formed within their
sides respectively, pass one within the other or one over the other, whereby lateral
displacement or rotation is prevented, and longitudinal movement or adjustment
admitted.
To admit of the outer tubular member a, being drawn over the inner tubular
member b, for the clamping or locking of the same together after adjustment, a slit
or split a, is provided, so that by screwing up the bolt d, passing through the lugs
or ears c² of the clip c, the clip is contracted, and the upper parts of the walls
of the outer tubular member are closed upon the inner tubular member, hence the
clamping or affixing of the one member to the other.
In Figures 10 and 11, a is the outer tubular member, with an inside channel a",
forming an outside rib thereby, and is an inner tubular member with a coincident
and longitudinal rib 2, with the channel upon the inner side of the said member,
hence the keying of the said telescoping members together.
In Figure 12, the same parts are marked with the same letters of reference as the
preceding figures, as instead of employing one or four ribs, I may employ two,
three or other number as may be desired, or instead of the inside rib of the one
being formed from an outside longitudinal channel or sinking, I may make the said
rib by gathering the metal longitudinally on one side into a shallow feather, which
takes into an outside and sunken coincident depression made or formed within the
inner tube meniber.
In carrying out the manufacture of the key tubes, such as in Figures 1 to 9
and 12, I take tools such as represented in longitudinal vertical section in Figure 13,
consisting of a channel-forming die, consisting of a hub, with a mouthed or bell-
hole through its middle of the diameter of the tube under operation, with the same
fitted with an inward impressing roller, with its acting periphery extending in-
wardly from the inside walls of the hole through the die, so that as the tube of
the inside bore of the die is drawn therethrough, a longitudinal impress, channel or
groove is made.
Figure 14 is a part sectional view and part elevation of Figure 13 upon the
dotted lines X-X.
a is a tube, and e is a die, having a central and bell shaped or mouthed
hole e², through its middle, of an inside bore equal to the outside diameter of the
tube a.
f is a channel impressing roller, mounted within a groove or split within the said
die, and with the periphery f, coming inwards or projecting a little beyond the
walls of the hole e², to an extent equal to the depth of the longitudinal impress or
channel a², to be formed within the said tube a.

page_text: 92 is the head of a bulb mandril g, with a longitudinal groove g', formed within
the said head g², and with the said groove being coincident with or being presented
to the wheel, so that as the tube a is drawn through the die or hub in the
direction indicated by the arrow, the metal between the coincident planes of
the wheel and the groove in the bulb of the mandril is displaced inwardly, hence the
formation of the channel or groove a², upon the outer side, and an inside rib upon
the inner circumference of the inside walls of the tube.
Figure 15 represents tools employed in the formation of outside ribbed or inside
grooved key tubes as represented in Figures 10 and 11.
Figure 16 represents a section upon the dotted lines X-X Figure 15.
e is the die or hub, with a bell mouthed hole e, through its middle, of a bore
equal to the outside diameter of the tube a, to be impressed with an inside groove
or an outside rib a². g is a mandril, 2 its head, and y¹ is a roller carried by the
mandril, and is its periphery, which is presented to and comes coincident with
the groove e, formed within the walls of the bore e², of the die e, so that by
drawing the said tube longitudinally through the die in the direction indicated by
the arrow, the metal of the same is displaced outwardly and formed into an outside
rib or an inside groove a²
Different tools are employed for key channelling or key ribbing varying sized
tubes.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
clain is :-
First In the telescopic and adjustable parts of cycles, such for example as the
steering posts or adjustable heads, seat pillars, handle bars, brake rods and other
like telescoping or tube-over-tube parts, providing, forming or sinking within the
sides or walls of the respective members of the said parts, longitudinal and
coincident outside or inside channels, grooves or sinkings, so that the he formation
of the one takes within the she formation of the other, hence the preventing of the
said members from rotating one over the other or one within the other, while
permitting of the said members sliding longitudinally, substantially as described
and set forth.
Secondly-In the telescopic and adjustable parts of cycles, such for example as the
steering posts or adjustable heads, seat pillars, handle bars, brake rods and other
like telescoping or tube-over-tube parts, forming or providing one of the said
members with an inside or outside longitudinal rib or feather, which fits within a
like and coincident inside or outside sinking or channel of the other member,
whereby the said members are keyed against rotation, whilst leaving the same
capable of longitudinal adjustment, substantially as described and set forth.
Thirdly-In tools for the production of longitudinally channelled key tubes as
in Figures 1 to 9 and 12, the combination with a die e, having an impressing
roller, fitted within it, and with the periphery of the said roller projecting or
coming inwards of the walls of the bore e², of the same, of a mandril or a bulb
mandril, having an opposed longitudinal groove presented to the said roller,
substantially as described and set forth in Figures 13 and 14.
Fourthly In tools for the production of longitudinally channelled key tubes
as in Figures 10 and 11, the combination with a die e, having a bore e, with a
longitudinal groove e¹, formed within it, of a mandril or a bulb mandril, carrying
an impressing roller, with the periphery of the same being presented to the groove
within the die, and extending beyond the surface of the said mandril or bulb,
substantially as described and set forth.
