We, JOHN WILLIAM HOLLAND, of 10, Sparsholt Road, Crouch Hill, County
of Middlesex, Engineer, and ARTHUR ANTHONY, of Hawthorn Villa, Jeffcock Road,
Wolverhampton, County of Stafford, Cycle Maker, do hereby declare the nature of
this invention to be as follows:-
This invention relates to cycle components and comprises improved con-
structions of stay-retainers for mud-guard stays, fork crowns, and back forks,
all of these parts being expeditiously and cheaply pressed or stamped from
sheet metal.
The improved stay-retainer according to this invention comprises two plates,
face to face and having corrugations formed on their meeting faces to receive
the end of a double stay which in side elevation is of V-form: a set-screw or
tightening device acting upon the two plates in proximity to the grooved portions
of the same enables them to be moved apart so that the angular portion of the
stay can be lifted out of place without the necessity for disturbing the fastenings
by which the plates are retained in position on the spindle or other part of the
machine. The tightening device operates as easily to cause the plates to grip the
stay after it is inserted between them.
Instead of the grooves being formed in the meeting faces of two separate plates
the opposite ends of a single plate may be bent to meet and corrugated upon their
meeting faces.
A double stay of the kind described holds the mud guard very securely with
freedom from vibration, but the bottom of a single stay may be retained by a
similar appliance if its end be formed in some such manner that it cannot be
accidentally withdrawn endwise from a correspondingly shaped groove or corruga-
tion; a single retainer can be used to retain a single stay or a whole series of
stays as desired, and can be bent to bring the sides into any desired plane relatively
to the support of the retainer. The stay-retainer can be shaped or perforated to
take the cords or other parts of a dress-guard.
Conveniently the upper ends of the mud-guard stays can be provided with clips
similar to those at their lower ends, capable of being tightened by a screw to
cause them to grip the stay rod and also to grip bridge-pieces by which the
mud-guards are directly supported.
With reference to the fork crowns an advantageous construction according to this
invention is one in which there are three "plates," the uppermost plate being
stamped on the flat with a central downward projection and two side wings curved
to the shape of the curved portion of aD-section blade, the lower plate being
formed with a central elevation and two wings, so that when the lower plate is

page_text: placed in its intended position between the wings and the upper plate the cavities
of the latter are closed by the flat wings of the former; there is an intermediate
plate which also is provided with wings to close other portions of the D-shaped
cavity of the side wings of the top member.
A strong construction of fork crown according to this invention is obtainable
by stamping it from sheet metal in two parts, each part comprising a longitudinal
channelled portion to form one half of the stem of the crown, wings being bent
past each other from opposite sides of this portion and bent back upon themselves
in a form which provides loops to receive the top ends of the blades; the wings
with their blade-holders extend at different levels from the opposite halves of
the crown so that when the two halves are put face to face to obtain a complete
cylindrical stem, the wings on the lower side of one half come under the wing
of the upper side of the other half and vice versa, so that the end of each blade
is held in a pair of sockets. The steering tube is slotted endwise to receive the
web or diaphragm, which extends midway across the crown in a vertical plane,
being formed by the bending of the wings as aforesaid. The cylindrical portion
of the crown obtained as described is carried up sufficiently far to form a support
for the bottom ball-race of the steering head.
In another construction of this type of fork-crown the wings instead of being
bent across the central channelled portion are each bent out from that side at
which they originate, so that the central diaphragm is not produced.
In a further form the central portion of the crown is formed as two half tubes
with external flanges which latter receive between them the flanges of a pair of
sockets for the blades.
Or a crown may be produced by bending sheet material so as to form one blade
socket, the metal from opposite sides of this socket meeting and extending as a
rib towards the central portion at which it is bent outward cylindrically, meeting
again to form another rib at the opposite side of the crown at which it is once
more bent outwards and finally brought together again to form a second blade
socket. A crown of this kind may be divided upon a line which is not, as in
the foregoing example, transverse to the length of the machine, or may be made
in two parts with meeting flanges connected by rivets or otherwise, the flanges
being adapted to serve as lugs, brake-plunger guides, foot-rest supports or other-
wise.
If desired the central diaphragm, where such occurs, can be extended to enter
the steering-head tube, beyond the height of other portions of the crown.
Another form of fork crown according to this invention is cruciform in plan with
blade sockets at the ends of two of the arms the other two being extended to form
ribs additional to those which extend from the blade sockets towards the centre
of the crown; the four ribs thus produced are received in intersecting grooves
in the end of the steering tube.
The back fork end according to this invention may be made by stamping and
slotting a piece of sheet metal and folding it so that semi-tubular or channelled
portions thereof come together to form sockets of the required cross-section to
receive the ends of the chain stays; preferably a sheet metal liner is inserted
between the two sides of the fork end and bent up so as to go into the interior
of the tube, received in the socket produced as described.
The lugs for the back stays are formed on the back forks, and the ends of these
stays are received in sockets formed like the back fork ends and preferably bent
so as to bring the line of thrust of the back stays into the plane of the lug on
the fork end so that there may be no bending stress upon the pin which connects
those parts.

We, JOHN WILLIAM HOLLAND, Engineer, of 10, Sparsholt Road, Crouch Hill,
in the County of Middlesex, and ARTHUR ANTHONY, Cycle Maker, of Hawthorn
Villa, Jeffcock Road, Wolverhampton, in the County of Stafford, 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 cycle components and comprises improved constructions
of stay-retainers or clips for mud-guard stays, fork crowns, and back forks, all of
these parts being expeditiously and cheaply pressed or stamped from sheet metal.
The improved stay-retainer or clip according to this invention comprises two
plates having grooves or similar accommodation to receive and grip the end of a
stay. The plates are provided with a set screw or other tightening device, so that
the stay may be removed from the retainer when desired without disturbing the
fastenings by which the plates are retained in position on the spindle or other part
of the machine. The tightening device operates also to cause the plates to grip the
stay after it has been inserted between them.
The stay retainer may conveniently be made from a single piece of sheet metal
having grooves or corrugations formed in its opposite ends, the plate being bent
so that the corrugations upon the opposite ends meet face to face and thus provide
accommodation for the stay.
Stay retainers as described above are especially suitable for use in holding
the lower end of a double stay that is of V-form in side elevation, but the
bottom of a single stay may be retained by a similar appliance if its end be formed
in some such manner that it cannot be accidentally withdrawn endways from a
correspondingly shaped groove or corrugation. A single retainer or clip may be
used to retain a single stay or a whole series of stays as desired, and can be bent
to bring the sides into any desired plane relatively to the support of the retainer.
The stay retainer can be shaped or perforated to take the cords or other parts of
the dress guard.
Conveniently the upper ends of the mud-guard stays can be provided with
retainers similar to those at their lower ends, capable of being tightened by a
screw to cause them to grip the stay rod and also to grip bridge pieces by which
the mud-guards are directly supported.
Fork crowns and back fork ends according to this invention are made from
sheet metal pressed, stamped or otherwise shaped to form sockets for the various
members of the frame which they are intended to receive.
The back fork end according to this invention may be made by stamping and
slotting a piece of sheet metal and folding it so that semi-tubular or channelled
portions thereof come together to form sockets of the required cross-section to
receive the ends of the chain stays preferably a sheet metal liner is inserted between
the two sides of the fork end and bent up so as to go into the interior of the tube
received in the socket produced as described.
The lugs for the back stays are formed on the back forks and the ends of these
stays are received in sockets formed like the back fork ends and preferably bent so
as to bring the line of thrust of the back stays into the plane of the lug of the
fork end so that there may be no bending stress upon the pin which connects
Those parts.
In the accompanying drawings which illustrate by way of example various
constructions of cycle components all according to this invention.

page_text: Figures 1, 2 and 3 are perspective views of various forms of improved mud-guard
stay retainers.
Figures 4 and 5 are elevations at right angles to one another showing retainers
for the top ends of mud-guard stays which also form a support for the mud-guard
itself.
Figures 6 and 7, 8 and 9, 10, 11, 12, 13, 14, 15, 16, and 17, all show various
constructions of fork crowns according to this invention.
Figures 18 and 19 are respectively an elevation and a longitudinal section of a
back fork end, and
Figures 20 and 21 are similar views of a socket for receiving a back stay end.
With reference first to Figure 1, A is an improved mud-guard stay retainer
comprising two plates A¹ having grooves A² which receive the V-shaped end of
a double mud guard stay B. A set screw A³ and nut A are provided by means of
which the plates may be clamped together or loosened in order that the stay B
may be readily gripped or removed. The plates A¹ are perforated as at A5
to take the spindle or other part of the machine.
As shown in Figure 1 the set screw A³ is made with a large head in order that
it may form the means of attachment for a dress guard cord C.
In Figure 2 a similar stay retainer is shown which is however, made from one
piece of sheet metal and bent upon itself as at A6.
The clip illustrated in Figure 3 is similar to those shown in Figures 1 and 2
but has side wings A7 which are provided with holes A8 for attaching to the cord
or other part of the dress guard.
Figures 4 and 5 show retainers according to this invention which are adapted
to receive the top ends of the mud guard stays. They are formed in one piece with
a connecting bridge A which forms a support for the mud-guard itself. The
dotted portion in Figure 5 shows the shape of the clip at one end before it is
bent over.
Figures 6 and 7 show one construction of fork crown according to this invention
which is stamped from sheet metal in two similar parts one of which is shown
separately in Figure 6. Each part comprises a longitudinal channelled portion D¹
which forms one half of the stem of the crown, and wings D³ which are bent past
each other from opposite sides of the channelled portion DI and formed into
sockets D³ to receive the upper ends of the fork blades. The wings D2 with their
blade sockets D³ extend at different levels from the opposite halves of the crown
so that when the two halves are put face to face to obtain a complete cylindrical
stem the wing at the lower side of one half comes under the wing on the upper
side of the other half and vice versa, so that the end of each blade is held in a
pair of sockets. The fork stem, or steering tube E is slotted, as at E¹, to receive
the web or diaphragm which extends inidway across the crown in a vertical
plane, this web D being formed by the bending of the wings I)2 across the
channelled portions D¹. The cylindrical portion of the crown obtained as described
is carried up as at 15 sufficiently far to form a support for the bottom ball-race of
the steering head.
In Figures 8 and 9 another construction of this type of fork-crown is illustrated,
in which however the wings 12 instead of being bent across the central channelled
portion are each bent out from the side at which they originate so that the
central diaphragm 14 across the crown is not produced.
Figure 10 illustrates another form of fork-crown in which the central portion
comprises two channelled portions or half tubes D¹ with external flanges De which
receive between them the side wings D2 of a pair of blade sockets D³. The
flanges 16 and the side wings D2 are rivetted as at D7 or secured in any other
convenient manner.
The fork-crown illustrated in plan in Figure 11 is formed entirely from one
piece of sheet metal which is bent to form the cylindrical portion D), ribs or side 5
wings D2 and fork blade sockets D³, the ends of the stamping being formed with

page_text: lugs D which meet at the side of one of the sockets D³, and are rivetted or other-
wise fastened together.
Figure 12 is a plan of a fork-crown similar to that illustrated in Figure 11
except that it is made in two portions united by lugs 18 at each of the fork
blade sockets D³.
Figure 13 illustrates in plan a fork crown which is similar to that described
with reference to Figure 11, except that the ends of the strip of which the crown
is formed meet at lugs Dº in a vertical plane on the cylindrical portion D.
In Figure 14 a fork crown is illustrated similar to that described with reference
to Figure 13 except that it is made in two portions which are united by lugs D' at
opposite sides of the cylindrical portion D.
In the fork crown illustrated in Figure 15 the cylindrical portion is formed of
two half-tubes 11 with flanges 16 similar to those described with reference to
Figure 10, but in this case the fork blade sockets D3, side wings D2 and central
diaphragm or web are all formed from one piece of metal. The central
diaphragm 1 is extended to enter the fork stem E above the height of the rest of
the crown.
Figure 16 shows another construction of fork-crown made in two halves, each
half comprising a fork blade socket D and side wings D2 and having extensions or
flanges which extend at right angles to the wings D2 so that the centre of the
crown is cruciform in plan. The fork stem in this case is slotted as at E¹ to
receive the cross formed by the side wings 12 and the flanges D¹º.
Figure 17 illustrates in plan a fork-crown similar to that shown in Figure 16
in which, however, the flanges D10 are extended and bent round so as to enclose the
fork stem E.
Figures 18 and 19 show a back fork end J according to this invention. It is
made from one piece of sheet metal which is first bent at a point near the centre of
the strip as at The strip is then bent again in two places as at J2 so that
the ends, which are suitably shaped for the purpose, form a socket J3 around the
portion J2. The end of the back fork blade is inserted into the socket J³, and the
portion J2 passes inside the end of the fork blade and thus forms a liner for it.
A lug J is provided for the attachment of the back stay this is also stamped with
the strip. By stamping suitable openings in the strip a slot is formed at one end
which serves for the usual chain-adjustment device.
Figures 20 and 21 illustrate a socket K which may conveniently be used to
receive the end of the back stay. The socket K is made in a similar manner to
the back fork end J above described, being formed from one piece of metal which
is first bent as at K² to form a liner and then bent back on each side as at K² to form
the socket K3 which receives the end of the back stay.
If desired the liners may be separately formed of sheet metal and inserted in the
sockets.
When the fork-crowns are made with lugs, for example as in the forms illus-
trated in Figures 11, 12, 13 and 14 of the accompanying drawings, the lugs
may conveniently serve as brake-plunger-guides foot-rest-supports and the like.
