A communication from Herbert Lincoln Hall of Rochester in the State of
New York, United States of America Manufacturer
I ALFRED JULIUS BOULT of 111 Hatton Garden in the County of Middlesex,
Chartered Patent Agent do hereby declare the nature of this invention and 'n
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
In the accompanying drawings representing the improvements;
Fig. 1 is a side elevation of the rear wheel and part of the frame of a bicycle
with this invention attached.
Fig. 2 represents the manner of attaching the swinging frame to the upright
portion of the bicycle frame.
Fig. 3 is a plan of the same.
Fig. 4 is a front elevation of the same.
Fig. 5 is a side view of the clamp by which the spring roller is attached
to the frame.
Fig. 6 is a plan of the same.
Figs. 7 and 8 are detail views of modifications.
In the accompanying drawings, A represents the bicycle wheel, and B B¹, C
and portions of the bicycle frame. E is the swinging-frame, F the spring
roller and H the mud-guard strip, which extends over the wheel and protects
the rider from mud or dirt.
The manner of attaching the swinging frame will be understood from
Figures 2, and 4. The clip is attached to the upright B and extends in
each direction, being bent to form the wings b and c, one of which supports
the lip and the other the hook f. A pin g inserted in the lip serves as a
pivot on which the arm E swings. is a clamp-plate by which the clip a is
attached to the frame B, by means of the screws or bolts i . A slot is made in
the arm E, through which the pin or screw passes. The arm E is provided
on its lower side near its forward end with the notch n, Fig. 2, which engages
with the hook f, as indicated in Figs. 2 and 4, and retains the swinging frame
in position as shown in Fig. 1, with the strip H extended above the wheel. It
will be understood that the uprights B B on opposite sides of the wheel are
each provided with clips like a, with which the forward ends of the swinging
frame engage, cach clip being turned outwards, as indicated in Fig. 3.
The spring roller F is attached to the uprights BB in any suitable manner,-
such for instance as the clip o, clamp-plate and bolts and nuts shown in
Figs. 5 and 6. The forward end of the strip H is attached to the roller F,

page_text: which revolves freely on the pin ",-being provided in its interior with the
springs, one end of which is attached to the pin and the other to the roller.
The spring rotates the roller, and causes the strip to wind up thereon, when the
frame is detached from the clips and folded up into the position II', shown
by the dotted lines in Fig. 1. The bolts and nuts q permit the removal of the
clip and roller from the uprights, and the frame can also be removed by turning
it into the position indicated by the dotted lines E¹ in Fig. 2, in which condition
the flat-head on the ping comes in line with the slot 7, and the swinging frame
can be entirely taken off of the bicycle.
When the rider desires to fold up this improved mud-guard, he depresses the
outer end of the swinging frame E, thereby detaching the notches from the
hooks f, and then on drawing the frame outwards it will slide on the pins g as
far as the slots will permit, in which position the forward ends of the frame
will swing inside or behind the hooks f, the roller F will wind up the strip H,
and the frame can be folded up to the position indicated at H. To again
extend the mud-guard, the operations just described are repeated in reverse
order, or, the frame may be simply turned outwards, with the pins g in the
outer ends of the slots 7, in which case the ends of the frame will spring outwards
over the hooks f,-the edges of which are inclined or rounded for this purpose,
as indicated in Fig. 4. The frame E as shown consists of a flat bar of metal
bent into U-shape, but it will be obvious that it may be made of round wire, er
that the slots or notches may be made in separate pieces attached to it. The
spring-roller F may also if preferred be attached to the outer end of the frame,
in any suitable or preferred way.
In a modification shown in Fig. 7, the clip a¹ is attached directly to the axle
of the wheel, by a nut t or other suitable device. The construction in other
respects remains the same, the pin g and hook f being employed on the clip a'.
In another modification the wing c is perforated and the end of the arm E
is provided with a lug or projection, u, which engages in the perforation to hold
the arm in place, the spring being employed to maintain the engagement.
This spring as shown is attached at one end to the pin g and at the other to a
stud inserted in the arm, being protected if desired by a suitable cover a
soldered or otherwise fastened to the arm.
It will also be understood that the pins or rivets may be provided with
round instead of flat-heads, the clip a itself in this case being taken off the
uprights if it is desired to dispense with the mud-guard.
It will also be understood that under certain circumstances, the slot may he
formed in the clip, the pin being fastened in the frame and engaging in the
slot in the clip.
The improved mud-guard may be applied to the front wheel of a bicycle, er
to the wheels of any other type of vehicle. A curved or folding frame may be
employed underneath the flexible strip to give it a shape to conform approximately
to that of the wheel.
Having now particularly described and ascertained the nature of my said
invention, as communicated to me by my foreign correspondent and in what
manner the same is to be performed, I declare that what I claim is,--
1. The combination with the frame of a bicycle of the spring-roller F, the
extensible mud-guard sprip H, the slotted swinging and lengthwise-movable
frame E, provided with notches n, the clips a a, the pivots g inserted in the
clips on one side of the upright and engaging in the slots in the swinging frame,
and the hooks f attached to the clips on the other side of the uprights and
adapted to engage in the notches in the swinging frame, whereby the frame is
adapted to be disengaged from the clips to fold it up by a lengthwise movement
on the pivots in the slots, substantially as described.
2. The combination with the frame of a bicycle, of the spring-roller F, the
extensible mud-guard strip H, the slotted swinging frame E, provided with
2

as described.
