An Adjustable Mud Guard Bridge for Cycles.
JOHN FRANCIS DIMMACк Cycle Maker 48 Dudley Street Birmingham do
hereby declare the nature of this invention to be as follows:-
I form my bridge from two duplicated pieces of thin gauge sheet steel, or any
other suitable material of a shape to allow of their being clipped to the stays of a
cycle, each baring a tongue or extension which is slotted out parallel to its
length.
To use my improved bridge I attach the clips with their slotted tongues or
extensions to each of the two stays of the cycle and at any desired point so as to
allow of the two slotted plates to come in contact and slide freely one above the
other, for the purpose of adjustment.
A bolt and nut extending through the before mentioned slots, is used for the
purpose of securing the mud guard thereto.

I, JOHN FRANCIS DIMMACK, of 48, Dudley Street, in the City of Birmingham,
Cycle Maker, 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 of the hereindescribed improved adjustable mud guard
bridge for bicycles tricycles and other velocipedes and cycles such as motor
carriages. My improved mud guard bridge is so constructed that it can readily be
fixed to the back stays, or to the fork sides of the cycle and be readily removed
therefrom and so that it can be fixed on to stays or fork sides which are of various
sizes and at various widths apart.
I will describe my invention by referring to the accompanying drawing on
which
Fig. 1 is a front elevation and Fig. 2 is a plan of my invention fixed to the back
stays of a cycle and shewing also a portion of the mudguard carried by my
invention; Fig. 3 is a side elevation of the same and
Fig. 4 shews the two parts of my improved mudguard bridge separately;
Fig. 5 is a general view of a modified form of my invention and
Fig. 6 shews separately the parts of the mud guard bridge represented by
Fig. 5.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.

page_text: Referring firstly more particularly to Figs. 1, 2, 3 and 4, I form my improved
mud guard bridge of two parts marked respectively A and B each being made of
a thin sheet steel or other sheet metal blank of the shape which will be understood
by an examination of Fig. 4. The piece A has one part a' which is in the form of
a metal strip bent into a looped form so as to clip the side stay or fork side C¹ the
ends being pierced at a a³ and secured together by a cross bolt d¹ passing there-
through. Formed with the near side of the clip part a' there is a tongue or
projection at which stands out at right angles thereto and is somewhat longer than
half the distance between the two stays or fork sides C' C to which the mudguard
bridge is required to be fixed. The other part B of the mudguard bridge is made
with a looped clip 6 corresponding with the looped clip a¹ and having its ends
pierced at 63 for the bolt d to pass through to fix the clip b' to the stay or fork
side C² in the same manner as the clip a¹ is secured to the other stay or fork side C¹.
The part B has also a tongue or extension 6 formed with the clip part 6' and
corresponding with the tongue or extension a' and made to overlap the same as
shewn in Figs. 1 and 2. The tongue a is slotted longitudinally at a, and the
tongue is similarly slotted longitudinally at 65 and through these slotted parts a
screw bolt e is passed and also through the mudguard thus securing the mud-
guard and the tongues a 6 of the bridge together. As the tongues or
extensions a 6 can slide one over the other it will be seen that the mudguard
bridge will suit cycles of which the stays C C are at different distances apart.
So as to keep the two tongues or extensions at 6 in line with each other and
prevent their coming apart when the mudguard bridge is detached from the cycle,
the outer end of the tongue or projection at may have two hooked clips a a
adapted to clip the body part of the tongue or extension 6, and this latter may
have two similar hooked parts 66 67 formed on its ends to embrace the tongue or
extension a as shewn in Figs. 1, 2 and 4.
Or I may obtain the same effect of keeping the two tongues or extensions a* b₁
in line by dispensing with the hooks a a b b and using a sheet metal clip G as
shewn in Figs. 5 and 6, the sides of which are bent so as to embrace the two
tongue extensions a 6, and there is a central hole gl in this clip G through which
the fixing bolt e passes to secure the clip G and the tongue extensions a* 6* and
mudguard together.
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 :-
1. The hereindescribed improved mudguard bridge for cycles consisting
essentially of the two sheet metal clips al adapted to clip the two stays or fork
sides respectively, the near side of each clip having a tongue or extension formed
with it which two tongues or extensions a 6 will slide one over the other and are
secured together and to the mudguard by a bolt passing therethrough, the said
parts being constructed and arranged together in the manner substantially as
herein before described and shewn by the accompanying drawing.
2. A mudguard bridge for cycles consisting essentially of the two parts A and B
constructed and arranged to fix to the stays or fork sides of the cycle and to each
other and to the mudguard substantially as herein before described and illustrated
by Figs. 1 to 4 of the accompanying drawing.
3. A mudguard bridge for cycles consisting essentially of the parts A B and G
constructed and arranged to fix to the stays or fork sides of the cycle and to each
other and to the mudguard substantially as herein before described and illustrated
by Figs. 5 and 6 of the accompanying drawing.
