Trouser and Dress Guard for Velocipedes.
I, JOHN HARRINGTON, of Claremont, West Street, Ryde, in the Isle of Wight,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
Many velocipedes are ridden by gentlemen without gear-cases, thus compelling
the rider to tie the bottoms of his trousers or tuck them into his boots or socks,
or otherwise clip them, in order to prevent their being caught and torn by the
chain wheel or cotter pin of the crank. It is also well known that ladies' dresses
are liable to be caught and torn by the said cotter pin.
In order to obviate this risk for gentlemen, and at the same time permit the
rider to wear his trousers as in walking, I provide a trouser-guard which may
be in the form of a disc attached to the chain wheel and extending a short dis-
tance beyond the teeth thereof, or in the form of a plate fixed to a tube of the
bottom fork and to the rear of the chain wheel, such guard-plate being formed
to overlap the teeth on the rear side of the chain wheel and extending a suitable
distance to the rear of the same.
The guards are provided with fittings and fastenings to secure them to various
descriptions of machines.
According to my invention I also enclose the boss of the crank and the cotter
pin in a shallow protecting case having spring arms to clip on to each side of
the crank, and a spring in its interior which bears against the said boss, by which
means the case is securely held in position; other means may however be
employed for attaching the case in position. The case is capable of being readily
attached and detached when it is so desired.
I preferably construct the protecting case in the following manner.
I stamp
a shallow box, out of sheet metal or other suitable material, consisting of a
circular disc with a cylindrical flange. I then separate the flange from the disc
by means of a saw cut for about a third of the entire circumference, after which
I divide that portion of the flange which has been separated into two equal parts.
I then bend outwards the two ends of the flange, which thus form spring arms
to bear on the sides of the crank. The spring which bears against the boss of
the crank is preferably made of an india-rubber ring stretched over two pins
standing up from the interior face of the disc on the opposite side to the spring
arms. The pins may be made from a piece of sheet metal having a narrow
central straight portion which has strips at right angles thereto at each end;
the strips are bent up parallel to the narrow central portion, which is then bent
to fit the interior of the circular flange, to which it is connected by means of a
rivet or in any other suitable manner.
The protecting case for the cotter pin may be used on ladies' machines which
are provided with a gear-case or dress-guard of any usual construction.
The invention is applicable to bicycles and other descriptions of velocipedes.

I, JOHN HARRINGTON, of Claremont, West Street, Ryde, in the Isle of Wight,
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:-
Many velocipedes are ridden by gentlemen without gear cases, thus compelling
the rider to tie the bottoms of his trousers or tuck them into his boots or socks,
or otherwise clip them in order to prevent their being caught and torn by the
chain wheel or by the cotter pin of the crank. It is also well known that ladies'
dresses are liable to be caught and torn by the said cotter pin.
My invention consists of means whereby the above inconveniences are obviated.
In order that my invention may be clearly understood and readily carried into
effect I will proceed aided by the accompanying drawings fully to describe the
same.
Fig. 1 is a side view of part of a bicycle fitted with one form of my dress
protecting shield.
Fig. 2 is a side view of part of a bicycle fitted with a slightly modified form
of shield.
Fig. 3 is an exterior view of a crank with my cotter pin protecting case applied
thereto and Fig. 4 is an interior view of the same.
Fig. 5 is an interior view of the protecting case shown at Figures 3 and 4.
Fig. 6 is an interior view of a circular cotter pin protecting case and Fig. 7
is an external view of the same.
The trousers guard shown in Fig. 1 consists of a disc a made of metal celluloid
or other suitable material attached to the chain wheel b by means of screws a¹.
As will be seen in the drawings the shield a extends beyond the teeth of the
chain wheel and thus prevents the trousers or dress being caught between the
chain and chain wheel.
The trousers guard shown in Fig. 2 consists of a shield
of any suitable
material fixed to the fork c by means of clips a². The shield a* is perforated to
allow the crank spindle to pass therethrough and fits between the chain wheel
and crank.
I preferably construct the protecting case for the cotter pin in the following
manner. I stamp out of sheet metal or other suitable material a shallow box
consisting of an exterior face d, and a flange e. I then separate the flange e from
the faced for a certain distance after which I divide that portion of the flange e
which has been separated into two equal parts. I then bend outwards the two
ends of the flange and thus form two spring arms e¹ which bear on the sides of
the crank when the case is in use.
In the protecting case shown at Figures 3, 4 and 5 to the interior of the flange e
at the opposite side to the spring arms e¹ I attach a C shaped spring clip to
clip around the end or boss fl of the crank f. This spring clip e² may be attached
to the flange e by means of a rivet e³ or it may be otherwise held in position.
In the circular protecting case shown at Figures 6 and 7 I prefer to attach
the spring clip to a cross bar e instead of to the flange e so that the case may
be central with the crank axle when in use.
The exterior face d may be ornamented by ribs as shown in the drawings or
otherwise as may be desired.
A protecting case as herein described will fit practically all cranks at present
in use and may be attached and detached without any trouble.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A trousers guard consisting of a disc or plate attached to a chain wheel or
bottom fork and extending beyond the teeth of the chain wheel, substantially
as herein shown and described.
2. A protecting case for the cotter pins of velocipede cranks substantially as
herein shown and described and for the purpose stated.
3. A protecting case for the cotter pins of velocipede cranks consisting of an
external face d, a flange e, spring arms e and a spring clip e² substantially as
herein shown and described and for the purpose stated.
4. A circular protecting case for the cotter pins of velocipede cranks consisting
of an external face d, a flange e, spring arms e¹ and a cross bar e carrying a
spring clip e, substantially as herein shown and described and for the purpose
stated.
