Improvements in Cycle Mud Guards.
I, EDWARD WARWICK of Sheffield Works, Alma Street, Aston in the County
of Warwick 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 consists in the improvements in cycle mud guards hereinafter set
forth by means of which a mud guard is produced very light in weight and with
hardened springing flexible supports.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is constructed and used.
Figure 1. represents a side view of mud-guard and supports.
Figure 2. represents a broken side view similar to Figure 1. but enlarged,
Figure 3. represents a front view of Figure 2 shewing the two side supports.
Figure 4. represents an enlarged view of side support connecting cheek.
Figure 5. represents an edge view of Figure 4.
Figure 6. represents a plan of Figure 4 viewed from the line CD.
Figure 7. represents an enlarged view of top part of side arm.
Figure 8. represents an enlarged front view of mud-guard and side supports
shewn part in elevation and part in section.
Figure 9. represents a plan of the underside of Figure 3 on the line E F.
Figure 10. represents a section of the flexible side supports.
Figure 11. represents an enlarged isometric view of bridge piece.
Figure 12. represents an isometric view of connecting cheek.
Figure 13. represents a section of Figure 15 on the line G H.
Figure 14. represents a section of Figure 15 on the line I .J.
Figure 1. represents an isometric view of one end of side support pressed into
the required shape to receive bridge tang or tang of connecting check.
In carrying out my invention provide a cycle mud guard a formed out of light
sheet metal or other suitable material turned over on each edge as shown at b.
I next provide the bridge piece on which is formed the two connecting cars de
as shewn in detail at Figure 11.
I next provide two pieces of flexible hardened rib steel with which to form the
two side arms k. I next provide two connecting cheeks as shewn in detail at
Figure 12.
next by means of suitable tools stamp, press, or otherwise shape each end of
each side arm into the shape shewn at Figures 13, 14, and 15, ready to receive the
tang ends de of bridge and two connecting checks, the flexibility being secured
by hardening and tempering the side arm after it has been stamped or pressed into
the shape represented at Figure 15.
The ends de of bridge piece would next be secured to the ends of two side
supports by means of rivets for by other equivalent means the tang ends g of two
side cheeks h, being next secured to the lower ends of flexible steel side supports k
by means of rivets or other equivalent fastenments.
The bridge (carrying the two side supports) would then be secured to the mud-
guard by means of the rivets m or other equivalent fastenments and my improved
mud-guard would then be ready to attach to a cycle wheel.
The improved mud-guard would be attached to the axial pin of wheel hub by
passing the centre holes n of connecting cheeks over the ends of hub axial-pin and
then securing the side cheeks on the axial pin by means of suitable nuts.

page_text: I am aware that cycle mudguards are in usc, made out of a segment of semi-
circular sheet metal, supported by two side armis connected to axial pin of cycle
wheel and such old style of mud-guard I do not claim.
What constitutes the main patentable novelty of my improved mud-guard is, the
utilization of hardened flexible steel in the construction of the side supports k
together with the use of very thin metal in the formation of the guard a such guard
being strengthened and improved by the turning over of the edges as shewn at
my improved mud-guard and side supports being strong and ductile and being much
less in weight than the oil style of mud guard.
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,
1st. The making of a cycle mud-guard by the utilization of hardened flexible
steel in the formation of the supporting arms k.
2nd. In a cycle mud-guard the turned over edges to strengthen the guard and
also to prevent the edges from cutting.
3rd. The combination of a bridge flexible side-arms and connecting checks h
to form a cycle mud-guard support.
