Improvements in and relating to Detachable Mud-guard Stays for
Bicycles and the like.
HENRY JEFFERY, Stocksbridge, near Sheffield, Manager, Steel Works, JOSEPH
Moxon, Hawthorn Brook, Stocksbridge, near Sheffield, Foreman, Steel Works,
do hereby declare the nature of this invention to be as follows:-
-
We make a hug from a piece of metal, one end being turned over to form a
round, flat, or other shaped socket to receive the end of the stay; the other end
of the lug is pierced so that it can be permanently fixed to any part of the
machine, but the wheel axle preferred so that it can be attached at the same
time as the other parts of the cycle, and the whole held firmly in their place with
the same ordinary nut. If the round socket is used additional grooves may be
prepared to hold the spring in position.
The stays are made from trough wire, the middle part of which is flattened
and pierced for attaching to the mud-guard. The ends of the stays are rounded,
flattened, or otherwise shaped to fit the sockets of the lugs. A spring made from
flat or round metal is inserted inside each end of the stay and fastened with a
pin put through the spring and the sides of the trough wire, to which it is rivetted.
The spring is so arranged that when it reaches the proper distance in the socket,
it is self-locking, and on a little pressure being applied to the button which is
fastened to the spring, the stay is immediately set at liberty, and can be detached
without interfering with any other part of the cycle.
The various parts of the stay and lug can be made in steel or other metal and
are hardened and tempered.

Improvements in and relating to Detachable Mud-guard Stays for
Bicycles and the like.
We, HENRY JEFFERY, of Stocksbridge, near Sheffield, Manager, Steel Works,
and JOSEPH MOXON, of Hawthorn Brook, Stocksbridge, near Sheffield, Foreman,
Steel Works, 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:-
We make a lug from a piece of metal, one end being turned over to form a

page_text: round, flat, or other shaped socket to receive the end of the stay: the other end
of the lug is pierced so that it can be permanently fixed to any part of the
machine, but, the wheel axle preferred so that it can be attached at the same
time as the other parts of the cycle,, and the wliofe held firmly in their place with
the same ordinary nut. If the round! socket. is, used additional grooves may be
prepared to hold the spring in position..
The stays are made from trough wire, the middle part of which is flattened
and pierced for attaching to the mud-guard. The ends of the stays are rounded,
flattened, or otherwise shaped to fit the sockets of the lugs. A spring made from
flat or round metal is inserted inside each end of the stay and fastened with a
pin put through the spring and the sides of the trough-wire to which it is rivetted.
The spring is so arranged that when it reaches the proper distance in the socket
it is self-locking, and on a little pressure being applied to the button which is
fastened to the spring, the stay is immediately set at liberty and can be detached
without interfering with any other part of the cycle.
The various parts of the stay and lug can be made in steel or other metal and
are hardened and tempered.
Our improvements are shewn in the drawings annexed.
Figure 1 is a side view of an ordinary bicycle with the mud guards attached.
Figure 2 is a side view and Figure 3 an end view of one of the sockets and the
lug piece of which it forms a part for the back wheel. Figures 2 and 3^ are
similar views of another socket and lug piece for the front wheel.
Figure 4 shews separately one of the stays and the socket pieces into which
the ends of the stay enter.
Figure 5 is a section on the line a b Figure 4 and Figure 6 a section at right
angles to Figure 5.
Figures and 8 shew two ways in which the portions of the stay containing
the inner ends of the springs. of the catches may be surrounded with a tubular
cap or casing to. exclude dirt.
In these drawings A is one of the lug pieces formed from a piece of sheet metal
turned over at one end to form the socket A¹ and with a hole A2 formed through
it at the other end by which it can be secured to any part of the machine.
In Figure 1 these lugs are shewn as being attached to the ends of the wheel
axles,, the ends of the axles passing through the holes A2 and the lugs clamped
and held securely by the ordinary retaining, nuts which screw on to the ends of
the axles.
B is the stay to which the mud guard C is rivetted-it is formed from one piece
of trough wire flattened and bent round at the middle as shewn. D are the
spring catches carried at the ends of the stay:
As will be seen the ends of the trough wire stay are bent inwards to make the
wire at these parts; correspond with the cross section of the sockets the two edges
of the wire being brought towards one another with sufficient space left to allow
the spring catch to extend outwards between them.
The inner end of each spring is formed to rest against the bottom of the trough
and is retained by a rivet E as shewn. The other end of the spring stands out
from the bottom of the trough and a notch D¹ is formed in it where it projects
out from the stay. The extreme end of the spring is rounded so that when the
ends of the stay are being inserted into the sockets A" these ends of the springs
may be pressed inwards and allow the ends of the stay to enter freely. When
the ends of the stay have been passed into the sockets far enough for the notches D¹
to be brought opposite to the sockets the catches fly outwards and the ends of the
notches coming against the ends of the sockets retain the stay securely. The
projecting shoulder D at the inner end of each notch prevents the ends of the stay
from being pressed down too far into the sockets: To release the stay from, the
sockets the spring catches can be pressed inwards by the small buttons D³ its
ends can then both, be withdrawn. simultaneously from the sockets and the mud
guard removed with it.

page_text: Where the mud guards pass between the fork carrying the front wheel or the
forked portion of the frame carrying the hind driving wheel they may be retained
by pins passing through them or be retained in any other suitable manner.
To prevent dirt passing down the trough wire into the end portions which
contain the spring catches the wire is filled in solid just above the inner end of
each spring by a solid filling piece B₁ the inner portion or stem of each spring
may also be completely enclosed by a tubular cap piece G surrounding the portion
of the stay which contains it. The extreme ends of the stay are also closed in
as shewn by bending over a portion of the wire.
To allow of the cap piece G being removed whenever required from around
the end of the spring-the rounding of the wire might be continued for some
distance inwards along the wire as shewn at Figure 7 so that the cap may be
slidden endwise along the wire. Or the tubular cap might be of thin spring
metal and be slotted longitudinally as shown at Figure 8 so that when moved
endwise in the opposite direction it might open out to pass the shoulder 12 of
the spring and so be slidden off from the end of the stay.
Where the central portion of the wire is flattened and bent round it is
strengthened by a strengthening piece H the ends of which are held by closing
the sides of the trough wire around them as shewn at Figures 4 and 5.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
1. Forming stays for carrying the mud guards of bicycles and the like of trough
wire with their ends formed to enter sockets attached to the machine and carrying
spring catches to hold to the sockets substantially as described.
2. The construction of the sockets and the lugs of which they form a part
substantially in the way described.
3. The construction of the stays from one piece of trough wire flattened at the
centre and bent round substantially as described.
4. The construction of the end portions of the stays in the ways described to
exclude dirt from the spring catches substantially as described.
5. The means described for strengthening the bend in the flattened portion
of the wire stay substantially as described.
