Improvements in or connected with Mud-guards for Velocipedes.
I, FREDERICK JACKSON, of 96 Southampton Row, Russell Square in the-
County of Loudon, Gentleman, do hereby declare the nature of this invention to
be as follows: —
The object of my invention is to construct the mud guards of velocipedes as
hereafter described, in such manner that they may be removed from position
and carried when not required with or without detaching the fixing or supporting
devices, and the mud guards may be extended and placed or fixed in position,
when desired, over the wheels in a ready and convenient manner without the
use of tools or special skill, and with greater facility than heretofore, while mud
guards constructed according to my said invention are decreased in weight, do
not rattle either when extended for use or contracted and out of use, and are
simple in construction.
I will describe my invention by way of example as applied to that type of
velocipede known as the rear driven or safety bicycle; according to my invention
I form the mud guards of celluloid, vulcanite, aluminium, or other suitable material,
and I divide the rear-wheel guard into two parts, the portion extending rearwards
being made removable, while the mud guard of the front wheel I also make
removable and construct same in such manner that the two detachable parts i.e.
the front wheel guard and the rear part of the back wheel guard, when taken
off, may be placed together and conveniently carried, leaving only the front
portion of the rear guard in fixed position. Such two removable portions, when
separated, may be carried by being attached by any convenient means, such as
clips or brackets to a suitable part of the framework of the machine, but
according to my invention, as I will now describe, I also provide an improved
means and arrangement for the disposal of the aforesaid parts which are supported
as follows: The fixed front portion of the rear wheel guard is attached at its
ends to an upper and a lower bridge piece (detachable or otherwise) arranged
say between the pairs of rear tubes; the rear detachable portion of this guard
(when in use) is held at one end upon the upper bridge piece by a thumb screw
(say a milled head screw) passing through the guard, while the extreme rear
end thereof is fixed by a similar screw to a forked stay jointed at its lower
end near the rear axle. The front wheel guard is screwed at its upper end by
a similar thumb screw passing through the guard and into a bracket piece
(detachable or otherwise) while its lower end is supported by a thumb screw
taking into a forked stay hinged near the front wheel axle. When the guards
are not required the back part of the rear guard is detached and slidden over
the fixed part of same with which it coincides, the front guard is removed, its
stay being turned up until its end comes below the bracket piece when the
thumb screw is screwed in and the stay is thus held and being situated between
the front fork is not visible; the front guard is then placed upon the two parts
of the rear guard and the thumb screws being passed through corresponding
holes in the guard the three parts are securely held out of the way, as also
being between the rear wheel and the frame are not even noticable. The rear
thunib screw also secures the rear stay in a similar position to the front stay.
I may form the forked stays of steel wire hinged to existing brackets on

page_text: machines now in use, to any construction of which my improved mud guard is
readily applicable, or the ends of the stays may be jointed to washers placed on
the axle pius and held by the usual nuts. Although the mud guards may be of
any approved section I preferably form the fixed part of the rear guard of flat
section with turned up edges (channel section) while the separate rear portion is
a curved section, by which means, the latter may be telescoped into the fixed
part, a segmental space being left between the two parts, whereby mud or the
like will not prevent the guard closing. It is obvious that in some cases the rear
wheel guard might be divided into more than two parts. I have also found that
when the parts composing the guard are detached and laid one upon another,
rattle (should such occur) is prevented by insertion of strips of raw hide, rubber,
or other suitable material, fitted so as to come between the adjacent parts. Mud
guards constructed according to my invention are equally applicable for front
driven bicycles and velocipedes generally.

COMPLETE SPECIFICATION.
Improvements in or connected with Mud-guards for Velocipedes.
I, FREDERICK JACKSON of 96 Southampton Row, Russell Square, in the
County of London, Gentleman, 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 :-
The object of my invention is to construct the mud guards of velocipedes as
hereafter described, in such manner, that they may be removed from position and
carried when not required with or without detaching the fixing or supporting
devices, and the mud guards may be extended and placed or fixed in position,
when desired, over the wheels in a ready and convenient manner without the use of
tools or special skill and with greater facility than heretofore, while mud guards
constructed according to my invention are decreased in weight, do not rattle either
when extended for use, or contracted and out of use, and are simple in construction.
I will describe my invention by way of example as applied to that type of
velocipede known as the rear driven or safety bicycle with reference to the
accompanying drawings whereon
Figure 1 illustrates in sectional side elevation, so much of a bicycle of safety
type as is necessary to show the application thereto of mud guards constructed
according to my invention the same being shown in their extended position, as when
in use.
Figure 2 is a view similar to Figure 1 but showing the mud guards removed
from position and carried upon the machine, and
•
Figures 3 to 10 inclusive are detail and detached views of parts and connections
hereafter referred to.
Similar letters. of reference refer to like parts in the several figures of the
drawings.
According to my invention I form the mud guards of celluloid, vulcanite,
aluminium or other suitable material and I divide the rear wheel guard into two
parts A and B, that portion B extending rearwards being made removable, while
the mud guard C of the front wheel I also make removable and construct same
in such manner that the two detachable parts i.e. the front wheel guard Cand
the rear part of the back wheel guard B, when taken off, may be placed
together, and conveniently carried, leaving only the front portion A of the rear
guard in fixed position. The two removable portions .e. the front wheel guard C

page_text: and the rear part B of the back wheel guard, I have found may be conveniently
made of equal size and shape, say of the shape shown by the detached plan view
of one of these parts shown at Figure 3 (drawn to a larger scale than the previous
figures) thus the two parts B and C when detached may be placed one on the other
for transport, packing or as hereafter described.
Such two removable portions B and C when detached from the machine may be
carried by being attached, by any convenient means, such as clips or brackets, to a
suitable part of the framework of the machine, but according to my invention, as
I will now describe, I also provide an improved means and arrangement for the
disposal of the aforesaid parts which are supported as follows. The fixed front
portion A of the rear wheel guard is attached at its ends to an upper bridge
piece D and a lower bridge piece E (detachable or otherwise) arranged say
between the pairs of rear tubes F G, a convenient construction of such bridge
pieces is shown detached in plan view at Figure 4, a rear view of the upper
tubes F and the bridge piece D in position being shown at Fig. 5. Both the
bridge pieces D and E are of similar construction, the said bridge pieces being
divided or split at their ends as shown at D', Fig. 4, which embrace the tubes F
and are clamped thereon by the screws D'; the rear detachable portion B of the
guard (when in use) is held at one end upon the upper bridge piece. D by a thumb
screw H, Figure 5, (say a milled head screw) passing through the guard B and
into the bridge piece D at H', Fig. 4, while the extreme rear end of the guard B
is fixed by a similar screw J, Figure 1, to a forked stay K jointed at its lower end
near the rear axle. The front wheel guard C is secured at its upper end by a
similar thumb screw L passing through the guard C and into a bracket piece M
(detachable or otherwise). A suitable construction of a detachable bracket M is
shown (on a larger scale) by the detached views, Figure 6 being a sectional
elevation, Figure 7 a plan and Figure 8 a cross section on the line X Y of Figure 7.
This bracket is composed of a split ring M closed around the neck of the front
fork by the hinged arm M³, the downwardly extending lug M2 receiving the end
of the guard C and the thumb screw L. The lower end of the guard C is
supported by a thumb screw N taking into a forked stay P hinged near the front
wheel axle. The forked stays P and K are conveniently jointed about their
respective axles by the device shown at Figure 9, consisting of a piece of bent
metal the tail end of which is formed with a hole through which the axle pin
passes and the part Q is then gripped by the ordinary tightening nuts.
When the guards are not required the back part B of the rear guard is detached
and slidden over the fixed front part A of same with which it coincides as shown
at Figure 2; the front guard C is removed, its stay P, see Figures 2 and dotted
lines Figure 6, being turned up until its end comes below the bracket piece M*
when the thumb screw L is screwed in and the stay P is thus held and being
situated between the front fork is not visible; the front guard C is then placed
upon the two parts A and B of the rear guard and the thumb screws H and J
being passed through corresponding holes in the guard the three parts are securely
held out of the way, as also being between the rear wheel and the frame are not
even noticable. The rear thumb screw H see Figures 2 and 5 also secures the
rear stay F in a similar position to the front stay P. 1 may in some cases form
the forked stays of steel wire hinged to existing brackets on machines now in use,
to any construction of which my improved mud guard is readily applicable, or
the ends of the stays may be jointed to washers as previously stated. Although
the mud guards may be of any approved section say as shown by Figure 81 may
in some cases form the fixed part A of the rear guard somewhat as shown by the
cross section Figure 10 with turned up edges H2 (channel section) while the
separate rear portion B is of a section having a greater curvature, by which
means the latter may be telescoped into the fixed part, a segmental space being
left between the two parts whereby mud or the like will not prevent the guard
closing; the front guard C should be wiped to remove mud before being slidden
into place.

page_text: It is obvious that in some cases the rear wheel guard might be divided into
more than two parts. I have also found that when the parts composing the guard
are detached and laid one upon another, rattle, (should such occur) is prevented
by insertion of strips of raw-hide, rubber, or other suitable material, fitted so as
to come between the adjacent parts.
Mud guards constructed according to my invention are equally applicable for
front driven bicycles and velocipedes generally.
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
as my improvements in or connected with mud guards for velocipedes is :-
:-
1. The wheel guard composed of two parts A B, the part A fixed between the
rear fork tubes to upper and lower brackets, the rear part B being detachably
secured at its upper end to the upper bracket, and a forked stay (adapted to fold
onto the rear fork when not required) which supports the rear end of part B when
in use substantially as set forth.
2. The combination of the front guard C, a bracket on the front tube fork and
a screw or equivalent L for adjustably attaching the front end of guard C, and a
forked stay P jointed near the front axle for supporting the lower end of guard C,
and adapted to fold onto the front fork upon removal of guard, in combination
with the divided rear guard, as claimed by Claim 1, all substantially as set
forth.
•
3. The combination with a removable front guard C and forked stay adapted to
fold into front fork when out of use, of the divided rear guard composed of a fixed
part A and a detachable part B and a supporting stay for same as previously
claimed, the two detachable parts B and C being adapted to slide into, or be
superposed upon, and secured to the fixed part. A of the guard when not required
for use all substantially as and for the purposes hereinbefore described and
illustrated with reference to the accompanying drawings and particularly with
reference to Figure 2.
4. The particular arrangement and construction of the attachment devices for
supporting when in use, the front guard C and the divided rear guard A B and the
means for fixture of parts C and B and of the stars K and P when out of use-all
substantially as described and illustrated with reference to the accompanying
drawing.
