CECIL. GOODRICH JULIUS DOLMAGE, M.A., LL.D., of 22, Upper Merrion Street,
Dublin, Ireland, Barrister-at-Law, and THOMAS FORSYTH, Assoc. Inst. C.E.I., of
5, Royal Terrace, l'airview, Clontarf, Co. Dublin, Civil Engineer, do
hereby declare the nature of this invention to be as follows:-
It is made of wood, or other suitable materials, nailed, rivetted, or bolted together.
It is adjusted by means of a cord, or other appropriate contrivance.
It has the following advantages;-
(1.) It is easily adjusted in a few seconds to fit any kind of bicycle gentleman's
or lady's with straight or curved frame.
(2.) Holds the bicycle perfectly rigid while both wheels are free to revolve;
facilitating repairs or cleaning, without any fear of the bicycle overturning.
(3.) Requires no clips or clamps to hold the bicycle-consequently there is no
chipping off of enamel.
(4.) Collapsible, light and portable.
(5.) After the stand has been adjusted to suit the bicycle, it is only necessary
to lift the latter on to it, and to fasten one strap or button.
(6.) The cord, or other suitable contrivance, is so arranged that it can be
lengthened or shortened without tying or untying any knots.
In order that the nature of this invention may be more fully understood we
refer to the sheet of drawings annexed, which shows substantially the form of
our improved stand, and the arrangements by which we secure its ready adjustment
for use with the various sorts of bicycles.

slack between any two of the holes in the strap (b), and which is fixed in position
by a winged nut.

(c) is the cord for adjusting the height.
is the arrangement for shortening or lengthening the aforesaid cord without
tying or untying knots.
Fig. 2 is a plan of Fig. 1, and shows the double framework in front marked (f f')
by which we enable curved frames of bicycles to be placed upon the stand.

following statement:--
described and ascertained in and by the
This stand is composed of wood or other suitable materials nailed, rivetted,
or bolted together. It is intended as a support for any safety bicycle of ordinary
make, whether of the straight-framed or curved-framed type; and will hold the
bicycle in such a manner that both wheels may then be freely rotated for purposes
of cleaning, lubricating, or repairing.
"
Referring to the sheet of drawings left with the Provisional Specification, it
will be seen that the main standards are made of two curved pieces "f fi" (see
Fig. 2 which is a plan of Fig. 1) kept at a certain distance apart by the bracket g
and the semi-cama," so as to allow the down-tube of the bicycle, when of tho
curved type, to pass in between. They are spread still further apart by the
distance piece "i" so as to form the back legs. The bracket ". Ji on which the
bracket of the bicycle rests, is held in position by a rivet or bolt passing right
through. The front legs "k" are hinged by rivets or bolts m m," and are
further curved and kept in position by the distance piece "." The curving of
the base is devised with the intention of giving additional width of base to the
stand, while the hinges or bolts "mm" are to allow of its being folded up.
(l
Fig. 1 is a side-elevation of the stand when in use, showing the semi-cam"
fitted upon an eccentric axis. This semi-cam has a curved groove on its circular face,
so as to fit closely to the down-tube of the bicycle, and by its eccentric motion
the slack between any two holes in the strap "" is taken up. It is held in position
by the winged nut (shown in the drawings) so as to allow of its being set at the
desired angle. The arrangement of strap and buckle "" is attached to "ff"
by nails or otherwise. Its object is, that when fastened across the down-tube the
bicycle may thus be prevented from turning over.
".
The cord is intended for the purpose of regulating the height of the stand
when in use, so that if necessary both wheels of the bicycle may be raised from
the ground. This cord is attached by a knot or otherwise to the distance piece "h"
between the front legs kk," and passes through three holes in the distance
piece between the back legs, in such a manner that the part of the cord on
which the strain comes passes over its free end, thus preventing it from slipping.
This arrangement of three holes is shown at "c"; and by means of it the length
of the aforesaid cord may be regulated with great exactness, and without any
tying or untying of knots.
"d" is a bent rod by which the front wheel of the bicycle may be maintained
in its normal direction. This bent rod is hinged on the front distance piece "h,"
and is made in a loop shape so as to allow the tyre of the front wheel to pass in
between. Further, it is placed in the most advantageous position possible being
thus quite clear of the front mudguard, should the bicycle employed be fitted with
such an appendage.
Referring again to Fig. 1, we explain the use of our stand as follows:-The
bicycle is to be placed upon it so that when the cord has been properly adjusted,
its bracket will rest upon the bracket "" and the lower portion of the tyre of its
front wheel will lie in the loop of the bent rod d," both wheels being at the
same time off the ground. The down-tube of the bicycle will thus be supported
by the semi-cam a"; portion of the former, when of the curved type, passing
between the double framework "f{"" (shown in Fig. 2). Then, having fastened
the strap & buckle arrangement over the down-tube, the slack between any
two holes in the former is taken up by pressing the semi-cam"
the under side of the said down-tube, and fixing it at the required angle by means
a" closely against
of the winged nut already alluded to. This done, the wheels may be rapidly
rotated, without any jolting of the bicycle or any fear of the erection toppling over.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. A bicycle stand fitted (as described in the foregoing) with a semi-cam grooved

page_text: upon its circular face, revolvable upon an eccentric axis, and capable of being
secured at any required angle by the tightening of a winged nut. The object of
said semi-cam is to take up the slack between any two holes in a strap and buckle
arrangement (such as we have described) by means of which the down-tube is
kept in position.
2. A bicycle stand in which the cord for regulating the height is secured by an
arrangement of three holes, such as has been described in the foregoing, in which
that part of the cord on which the strain comes passes over the free end thus
preventing it from slipping.
3. A bicycle stand in which the normal direction of the front wheel of the
bicycle is secured by a bent rod in the form of a loop, which bent rod is fixed (as
described) in such a position that it may be out of the way of the front mudguard,
should the bicycle employed be fitted with such an appendage.
4. A bicycle stand in which the legs are curved outwards in such a manner as
to give increased wideness of base and therefore increased stability.
5. A bicycle stand, such as has been described in the foregoing, in which that
part of the framework between the bracket and the semi-cam is made of two pieces
set at such a distance apart that down-tubes of bicycles when curved may pass
readily in between.
