page_text: I, FREDERICK ARTHUR WALTON of Vyse Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates first, to the construction of the framing parts of cycles,
secondly, to an adjustable socket for receiving the seat pillars of cycles, and thirdly,
to a cycle chain adjustment.
The object of the first part of my invention is a frame constructed of bolted-together
members instead of connecting the said members together by brazing their ends
within junction lugs, whereby the cost of manufacture of such framings is greatly
reduced, whilst the assembled members admit of being readily collapsed so that
little rooin is taken up by them in transit or storage.
The second part of the invention has for its object to so mount the seat pillar
socket that the same can be turned or tilted to any angle without the employment
of a separate tilting device in the saddle itself, whilst the object of the third part
is to so hang the bottom bracket that it is capable of an angular adjustment relative to
the chain.
In carrying out the first part of my improvements in connection with a diamond
pattern cycle frame, I take a series of half-round or other sectioned tubular members,
with their ends flattened out plate-wise and pierced into eyed lugs or ears, where-
through bolts or pins pass, in securing together the said members for building up a
frame. Thus, instead of making up a frame from single stay members, I make each
of the said stays up of two or more members, either running side by side and being
separated from each other to any desired extent. The top bar I make up of two
side by side but preferably separated and parallel tubular members with the front eyed
ends coming upon the the two opposite sides of an eyed lug or bracket extension
directed outwardly from the top and back portions of the sleeve or socket of the head
and then being secured together by a bolt passing through the whole.
The after ends, of the members which may be separated to a greater distance apart
than the fore ends, come coincident with the piercings in the eyed ends of the pair of
back stays and seat stays and also with the eyed bracket of a seat pillar socket, and
are there collectively bolted together. The bottom ends of the pair of back stays
may be separated to a greater extent than the top end and are connected to the eyed
outer ends of the chain stays, which are also separated from each other than their
inner ends which are bolted to a part of the bottom bracket. The outer ends of the
back stays and chain stays are bolted together by bolts or equivalents.
The bottom diagonal stay is made up also of two members, with the eyed front ends
united to the back of the bottom of the sleeve, whilst their inner ends are bolted, in
common with the adjacent ends of the component members of the seat stay and the
chain stays, to an eyed lug on the bottom bracket, which has a quadrant-slotted arm
or plate wherethrough a bolt directed through it and one or both of the members of
the seat rod, passes.
Supplementary bracing stays may he employed between the dual component

page_text: members of each stay, and I wish it to be understood that I do not limit myself to
the extent of the separation of the said members, as each stay may be made up of
a series of loose components, separated from each other by distance pieces and
arranged so as to constitute a trussed beam.
The seat pillar socket is made to swing upon a separate pin or centre, or upon the
pin or pins uniting the overlapping ends of the members, so that it is only necessary
to loosen a nut or nuts when the requisite angular adjustment of the same relative
to the frame can be obtained.
The bottom bracket is arranged so as to admit of swinging or changing its angular
position when one of the bolts or the locking or joint bolt, or both is or are slackened
thus increasing or diminishing the distance between it and the hub for the purpose
of adjusting the chain.
A further form of chain adjustment is constructed as follows:-
The overlapping and meeting ends of the component stays of each side carry
a plate or bolted-on piece, having a series of ribs or undulations on its inner side,
whilst the bottom bracket has directed upwardly from its joint lug, a slotted out
block or equivalent, the ends of which carry a rib, tooth or detent adapted to engage
between a pair of the ribs or undulations on the locking plates. A bolt is passed
through both the plates and a hole in the block and which, when tightened up,
draws the said plates and ends of the block into close contact with one another and
with the teeth or ribs of the one engaging the ribs or undulations of the other, hence
the bracket is firmly clamped in its adjusted position.
I wish it to be understood that the component parts of each stay may be made
flat, and in order to increase their strength may be longitudinally corrugated, beaded
or the like, or they may be made up of a series of thin laminated plates of a paragon
or like cross section which may be slightly separated from one another and have
intervening distance pieces.
Instead of hollow tubes solid or partly solid rods of metal, wood or other material or
a series of stout wires interwoven into tubular forms may be employed.
The application of my improvements to other cycle frames differs in no essential
respect from its application to a diamond cycle frame as herein-described.

I FREDERICK ARTHUR WALTON of Vyse Street in the City of Birmingham,
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 first, to the construction of the framing parts of cycles,
secondly, to an adjustable socket for receiving the seat pillar of cycles, and thirdly, to
a cycle chain adjustments.
The object of the first part of my invention is to construct a frame of bolted-
together members instead of connecting the said members together by brazing their
ends within junction lugs, whereby the cost of manufacture of such framings is
greatly reduced, whilst the assembled members admit of being readily collapsed so
that little room is taken up by them in transit or storage.
The second part of the invention has for its object to so mount the seat-pillar

page_text: socket that the same can be turned or tilted to any angle without the employment of
a separate tilting device in the saddle itself, whilst the object of the third part is to
so hang the bottom bracket that it is capable of an angular adjustable relative to
the chain.
Figure 1 of the accompanying drawings represents a side elevation of the fore part
or steering head of the framing of a safety bicycle constructed of bolted together
members according to one form of the first part of my invention.
Figure 2 is a vertical section of figure 1.
Figure 3 is a horizontal section of figure 1 upon the dotted lines x.
Figure 4 is an elevation of the back upper end of the framing, showing also the
seat pillar and the means of adjusting and locking the angle of the same.
Figure 5 is a topside plan of figure 4.
Figure 6 is a transverse longitudinal section of figure 4 upon the dotted line x¹.
Figure 7 represents the component elements of that portion of the frame and its
accessory fittings shown in figures 4, 5 and 6 separately.
Figure 8 represents in side elevation, the method of connecting the bottom bracket
or crank axle bearing to the frame and of adjusting the same so as to increase or
diminish the distance between it and the back wheel hub whereby the driving
chain is tensioned or slackened.
Figure 9 is a transverse vertical section of figure 8 upon the dotted line x².
Figure 10 is a cross section of figure 9 upon the dotted line 2³.
.
Figure 11 represents the serrated locking plates by which the bottom bracket is
prevented from slipping out of its adjusted position.
The same letters of reference indicate corresponding parts in the several figures of
the drawings.
In carrying out the first part of my improvements, in connection with a diamond-
pattern safety bicycle frame, I take a series of half-round or other sectioned tubular
members a, b, c, d, and e, with both their ends a¹, b', c', d', e¹, flattened out plate-
wise and pierced into eyed lugs or ears a², b², c², d², e², wherethrough bolts or
pins f, f, f, f, pass, in securing together the said members for building up a frame.
Thus, instead of making up a frame from single tubes or members, I make the same
from series of pairs of twin members running side by side and being separated from
each other to any desired extent. The top bar a, I make up of two side by side but
preferably separated and parallel tubular members a³, as, with the front eyed ends a²
coming upon the two opposite sides g¹, of an eyed lug or bracket extension g,
directed outwardly from the top and back portions of the sleeve or socket h', of
the steering head h, of the machine and then being secured together by bolts ƒ, f',
passing through the whole.
The after ends a³, of the said members a³, at, which may be separated to a greater
distance apart than the fore ends, come coincident with the piercings in the eyed
ends e, c, of the pairs of side by side members or lengths constituting the back
stays e, and seat stay c, and also with the eyed bracket i, of a seat pillar socket i,
wherein the seat pillar j, takes, and are there collectively bolted together by the
cross bolt f. The bottom ends of the pair of back stays e, may be separated to a
greater extent than the top ends e', and are connected to the eyed outer ends of the
chain stays d, which are also separated from each other to a greater distance than
their inner flattened ends d', which are bolted to a part of the bottom bracket j.
The outer ends of the back stays and chain stays may either be bolted together by
separate bolts or equivalents, or by the screwed ends of the spindle of the back wheel
hub taking through the coincident eyed ends of the said stays and then receiving
locking nuts.
The front diagonal stay b, is made up also of two members with the eyed front
plate ends 62, united to the lug g, at the back of the steering head sleeve h¹, being
there secured by the bolts f, f, the former of which also serves to secure the top
rail members a, The inner ends 3, of the said front diagonal members are
bolted in common with the adjacent ends c, d, of the component members of the
seat stay c, and the chain stays d, to an eyed lug or upward extension j², on the

page_text: bottom bracket wherethrough the bolt f, passes for securing the said ends of the
members together and to the bottom bracket.
Instead of two members arranged or pairs side by side as described three or other
number of tubular lengths may be employed.
Supplementary bracing stays may be employed between the component members
of each stay, and I wish it to be understood that I do not limit myself to the exact
dispositions and extent of the separation of the said members, as each stay may be
made up of a series of loose components, separated from each other by distance pieces
and arranged so as to constitute a trussed beam.
The seat pillar socket is made to swing upon the pin f³, uniting the overlapping
ends of the members a, c and e, so that it is only necessary to loosen a nut or nuts
when the requisite angular adjustment of the same relative to the frame can be
obtained, whilst to more effectually secure the said socket in its adjusted position, it
has a winged extension j', which are passed between the members c, and then turned
back around or partially embracing the said members. Or the said socket may be
mounted and adjusted upon a separate pin, independent of the pin which clamps the
ends of the members to the lugs. The bottom bracket is arranged so as to admit of
swinging or changing its angular position when the locking or joint bolt f*, is
slackened, thus increasing or diminishing the distance between it and the hub of the
back wheel for the purpose of adjusting the tension of the driving chain.
The overlapping and meeting ends of the framing stays b, c and d, of each side
carry a plate or bolted-on piece k, having a series of ribs or undulations, on its
inner side, whilst the bottom bracket has directed upwardly from it a slotted out
block 2, or equivalent, the edges j, of which carry a rib, tooth or detent jo, adapted
to engage between a pair of the ribs or undulations on the locking plates. The
bolt, is passed through the pierced ends of the tubes and also through both the
locking plates and a hole jo, in the block 3, so that when tightened up, the said pin
draws the said plates and ends of the block into close contact with one another
and with the teeth or ribs of the one engaging the ribs or undulations of the other
hence the bracket is firmly clamped in its adjusted position.
Or the bottom bracket may carry quadrant slotted plates or cheeks at its opposite
ends through which the clamping pin may pass, and the framing ends threaded
upon the extended ends of the bolt may be clamped up against the faces of the
quadrant plates, which are preferably serrated, by the screwing up of nuts.
I propose to corrugate, roughen or serrate the whole of the overlapping parts of the
component members and lugs or junctions of the steering head, saddle pillar clip and
bottom bracket, thereby greatly enhancing the rigidity of the framing by preventing
the parts slipping upon one another.
I wish it to be understood that the component parts of each stay may be made flat
or of any other suitable section and in order to increase their strength they may
be longitudinally corrugated, beaded or the like, or they may be made up of a series
of thin laminated plates of a paragon or like cross section which may be slightly
separated from one another and have intervening distance pieces.
Instead of hollow tubes solid or partly solid rods of metal, wood or other material or
a series of stout wires interwoven into tubular forms may be employed.
The application of my improvements to other cycle frames differs in no essential
respect from its application to a diamond pattern safety bicycle frame, as herein
described.
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
claim is :-
2
First Building up cycle frames from a series of component members and parts
with portions of them overlanning each other and being connected together by cross

page_text: lengths, arranged in pairs or in multiple order and connected to lugs or equivalents
upon the seat pillar clip, steering head and bottom bracket, by cross bolting,
substantially as described and set forth
Thirdly The improvements in the construction and arrangement of the com-
ponent members of the primary framings of cycles substantially as herein described
and set forth.
Fourthly The means of adjusting and clamping the saddle pin for tilting the
seat, substantially as herein described and set forth.
:-
Fifthly Adjusting the tension of the drive chain by a swinging bottom bracket
mounted upon the same pin as that which secures the component members of the
primary frame thereto, and with the opposed faces of the overlapping parts toothed,
serrated or roughened to prevent shifting after adjustment, substantially as described
and set forth.
