Improvements in Mud-guards for Cycles.
1. CHARLES THOMAS BROCK SANGSTER, Works Manager of The Cycle
Components Manufacturing Company Limited, of Bournbrook, near the City
of Birmingham, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to detail improvements in the mud-guards of cycles,
with the principal object of effecting the ready detachment of the same.
To detach mud-guards as now constructed, it is necessary to unscrew the lock
nuts from the spindle ends in order to clear the way for the removal of the eyed
ends of the guard stays and during this process, the spindle is loosened and
the adjustment of the chain is often interfered with, but according to my
improvements, the mud-guards admit of being detached without the removal of any
of the nuts.
My said invention consists first, in spring metal clips threaded upon the wheel
spindle ends, inwards of the lock nuts, and wherein the ends of the mud-guard
stays slide and are clamped or released by slightly tightening or slackening the
said nuts; secondly, in an improved construction of inud-guard stay made from
sheet metal, and thirdly, in a sheet metal attachment bracket for connecting a mud
guard to the stay thereof.
In carrying out the first part of my invention, I cut out from sheet steel, a blank
of suitable length and width and having rounded and pierced ends. This blank
I fold upon itself, with the piercings in the said rounded ends coming coincident,
whilst the middle part of the blank is left in the form of a vertical sleeve or beaded
part running across the breadth of the clip and wherein the end of a mud guard
stay takes.
In use, one of these clips is fitted onto the lower end of each stay and the
pierced parts thereof are placed over the spindle end and clamped there by the
screwing up of the lock-nut. In order to detach the guards, it is simply necessary
to slightly slacken the lock nuts, when the stay ends can be withdrawn from the
sleeves or tubular parts of the clips without interfering with the adjustment of the
chain or other parts of a machine.
Clips constructed according to my invention are applicable for use on both the
front and back wheels of cycles.
In carrying out the second part of my invention, in order to save weight, I
make mud-guard stays from strips or lengths of sheet metal, drawn, rolled or
otherwise fashioned into a tubular form of any desired cross section.
In carrying out the third part of my invention, I form the bridge or bracket by
which the mud-guard is secured to its stays by cutting out a rectangular strip of
steel and then fashioning the ends of the same by drawing through tools, dies and
pressure or otherwise, into box ends or sleeves, open at their lower presented parts
and closed at top and of a cross section according with the section of the mud-
guard stays which are brazed rivetted or otherwise secured therein.
The bracket thus formed is secured by rivetting or otherwise preferably to

page_text: the underside of the mud-guard, which may be of a corrugated or other cross
section.

Improvements in Mud-guards for Cycles.
I, CHARLES THOMAS BROCK SANGSTER, Works Manager of The Cycle
Components Manufacturing Company Limited, of Bournbrook, near the City
of Birmingham, 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 :-
My invention has reference to detail improvements in the mud-guards of cycles,
with the principal object of effecting the ready detachment of the same from
a cycle.
To detach mud-guards as now constructed, it is necessary to remove the lock
nuts from the ends of the wheel spindles in order to clear the way for the removal
of the eyed attachment ends of the mud-guard stays and during this operation the
spindle is loosened and the adjustment of the chain is often interfered with, but
according to my improvements, the mud-guards admit of being detached without
having to first remove any of the nuts.
My said invention consists first, in spring metal clips or adjustable cups or
adjustable cups threaded upon the wheel spindle ends, inwards of the lock nuts,
and wherein the ends of the mud-guard stays take or slide and are clamped or released
by slightly tightening or slackening the said nuts; secondly, in an improved
construction of mud-guard stay made from sheet metal, and thirdly, in a sheet
metal attachment bracket or bridge piece for connecting a mud guard to the stays
thereof.
Figure 1 of the accompanying drawing represents the framing of a safety
bicycle, fitted with mud guards attached and provided with stays and connecting
brackets constructed according to my improvements.
Figure 2 represents an elevation of spring stay clip which is threaded on the end
of the wheel spindle and is drawn around the end of the said stay by the tightening
up of the lock nut.
Figure 3 is an edge view of the same.
Figure 4 is a vertical section of a clip, showing a stay in position within the
socket thereof; Figure 5 is an elevation of Figure 4 and Figure 6 an underside
plan thereof.
Figure 7 is a blank from which such a clip is made.
Figure 8 is a plan of a part of a mud-guard fitted with my improved connection
bridge, the stays being shown in section."
Figure 9 represents a section of the said guard and bridge, and also shows,
partly in elevation and partly in section, the hollow or tubular stays and the spring
attachment clips in position on the inward ends of the said stays.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
In carrying out my invention in connection with the spring stay clip a, I cut out
from sheet steel a blank a', Figure 7, of suitable length and width and having
rounded and pierced ends aº. This blank I fold upon itself, with the piercings a³,

page_text: in the said rounded ends coming coincident, whilst the middle part a³, of the blank
is left in the form of a vertical sleeve or beaded part a', running across the breadth
of the clip and wherein the end 6', of a mud guard stay b, takes.
In use, one of these clips a, is fitted onto the lower end 6', of each stay and the
pierced parts a', thereof are placed over the end of a wheel spindle and is
clamped there by the screwing up of the lock-nut c. In order to detach the
guards, it is simply necessary to slightly slacken the lock nuts, when the stay
ends can be withdrawn from the sleeves or tubular parts at of the clips without
interfering with the adjustment of the chain or other parts of a machine.
Clips constructed according to my invention are applicable for use on both the
front and back wheels of cycles.
In order to save weight, I make mud-guard stays b, from strips or lengths of
sheet metal, drawn, rolled or otherwise fashioned into a tubular or hollow form of
any desired cross section. The bridge or bracket e, by which the mud-guard, is
secured to its stays b, is formed by cutting out a rectangular strip of steel and then
fashioning the ends, of the same by drawing through tools, dies and pressure
or otherwise, into box ends or sleeves e, open at their lower presented parts e³.
and closed at top e, and of a cross section according with the section of the mud-
guard stays which are secured therein by brazing, rivetting or closing the metal of
the cap or box ends around the same or otherwise.
The bracket thus formed is secured by rivettings f¹, (or otherwise) preferably to
the underside of the mud-guard f, whieh may be corrugated as shown or of any
other cross section.
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 1
claim is :-
First. In mud guards for cycles, securing the same in position by means of
spring metal clips, or adjustable clips, threaded upon a wheel spindle, or its
equivalent, inwards of the lock nuts, and adapted to embrace and hold the ends of
the mud guard stays, which are clamped or released by the tightening or slackening
of the said lock nuts, substantially as described and set forth.
Secondly. In mud guard stays, making the same from strips or lengths of sheet
metal, drawn, rolled or otherwise fashioned into a tubular or hollow form of any
desired cross section, substantially as described and set forth.
Thirdly. A bridge or bracket for securing mud guards to their stays having the
ends or parts thereof fashioned into boxes, caps or sleeves, wherein the upper ends
of the stays are secured, and with the said bridge or bracket being attached
preferably to the inside of a mud guard by rivetting or otherwise, substantially as
described and set forth.
Fourthly. The several improvements in mud guards and in the accessory fittings
thereof, substantially as herein described and set forth.
Dated this 29th day of March 1897.
