I, GEORGE CROYDON MARKS of 18, Southampton Buildings, Chancery Lane,
London W.C. Consulting Engineer (a communication from abroad by Emile Marie
of 42, Boulevard Bonne-Nouvelle, Paris), do hereby declare the nature of this
invention to be as follows:-
This invention relates to a construction of stand or support which I have
designed with the object of facilitating the assembling and the taking apart of the
several parts or components of safety bicycles, by enabling the frame or body of
these machines to be firmly held in all positions.
The improved stand or support is composed essentially of a vertical shank or
stem provided with feet at its lower end that serve to support it firmly upon the
ground and with a socket or bead at its upper end in which is mounted and held
the lower end of a second swivelling stem which terminates below its pivotting
point in a toothed are or sector which is adapted to be actuated by means of a
worm situated upon the socket head of the supporting stem, and which is itself
arranged to be operated by means of a crank handle.
The upper end of the second stem ends in a socket or head in which is mounted
the lower end of a third swivelling stem provided with a hole beneath its pivotting
point and arranged to correspond with a hole formed in the sides of the socket or
head, in such a manner that the third stem can, by means of a pin, be fixed in a
vertical position in the prolongation of the second stem.
Two symmetrical shoulders are formed on the third stem which allow the latter
to assume two opposite positions at right angles to the second stem, viz., one
position to the right hand, and the other position to the left hand of said stem,
the said shoulders bearing in said positions upon corresponding faced parts on the
sides of the socket or head.
At the upper end of this third stem there is mounted by means of a socket or
head adapted to pivot about a pin, a fourth stem which is bent at right angles to
itself and then bent back into its former direction. This last bent back portion
carries clamping collars in which the desired part of the bicycle can be fixed and
is held according to the operation or the work to be done.
The upper end of the third stem is provided with a lug standing out at right
angles thereto, while a hole is provided therein, at a distance from the pivotting
centre corresponding to that of another hole provided in the stem itself immediately
beneath the pivotting centre.
The lower extremity of the fourth stem is bifurcated and is provided with two
holes on each side corresponding to those upon the upper extremity of the third
stem, the one for receiving a pivotting pin for carrying the stem while the other
hole beneath is provided to line with the holes provided in the lug or that beneath
the pivotting hole on the third stem, so that on the introduction of a pin through
such holes in line, the fourth stem may assume either an upright position or a
position at right angles thereto according as the hole immediately beneath the
pivotting hole or the hole in the lug is engaged.
It will therefore be seen that in the first place the whole appliance may be
adjusted from its support by means of the worm and sector into any inclined
position in one plane while the third and fourth stems may assume a vertical or an

page_text: horizontal position on either side from the upper head or socket of the second
stem in a plane at right angles to that of the movement of the first stem: and the
fourth stem is again capable of assuming two positions relatively to the third stem.
It will be understood also that if the fourth stem is turned upon the head of the
third so that its bent extremity is upon the opposite side then such stem is again
capable of assuming two other positions relatively to the third sten. It will be
seen therefore that it is possible to place the clamping or holding collars in a great
number of positions for the greater convenience of readily assembling and taking
apart the various portions of the cycle.

I, GEORGE CROYDON MARKS, of 18 Southampton Buildings, Chancery Lane,
London, W.C., Consulting Engineer (a communication from abroad by Emile
Marie, of 42 Boulevard Boune-Nouvelle, Paris), 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 relates to a construction of stand or support which I have
designed with the object of facilitating the assembling and the taking apart of the
several parts or components of safety bicycles, by enabling the frame or body of
these machines to be firmly held in all positions.
The invention is illustrated in the accompanying sheet of drawings in which
Figure 1 is an elevation and
Figure 2 a partial elevation at right angles to Figure 1.
Referring to these figures the improved stand or support is composed essentially
of a vertical shank or stem A provided with feet B B at its lower end that serve
to support it firmly upon the ground; and with a socket or head C at its upper
end in which is mounted and held the lower end F of a second swivelling stem E
which terminates below its pivotting point D in a toothed arc or sector F which is
adapted to be actuated by means of a worm G situated upon the socket head C of
the supporting stem, A, and which is itself arranged to be operated by means of a
crank handle H.
The upper end of the second stem E ends in a socket or head I in which is
mounted the lower end of a third swivelling stem J provided with a hole beneath
its pivotting point and arranged to correspond with a hole L formed in the sides
of the socket or head, in such a manner that the third stem J can, by means of a
pin M, be fixed in a vertical position in the prolongation of the second stem E.
Two symmetrical shoulders N N¹ are formed on the third stem J which allow
the latter to assume two opposite positions at right angles to the second stem E,
this is clearly shown by dotted lines on Figure 1 viz., one position to the right
hand and one position to the left hand of E the shoulders N N¹ bearing in said
positions upon corresponding faced parts on the sides of the socket or head I.
At the upper end of the third stem J there is mounted by means of a socket or
head O adapted to pivot about a pin O' a fourth stem O' which is bent at right
angles to itself and then bent back into its former direction. This last bent back
portion carries clamping collars P P in which the desired part of the bicycle can
be fixed and is held according to the operation or the work to be done.

page_text: The upper end of the third stem J is provided with a lug Q standing out at
right angles thereto, while a hole Q' is provided therein, at a distance from the
pivotting centre O' corresponding to that of another hole Q provided in the stem
itself immediately beneath the pivotting centre O¹.
The lower extremity of the fourth stem O" forms the fork R Figure 2 and is
provided with two holes on each side corresponding to those upon the upper
extremity of the third stem J, the one for receiving a pivotting pin O' for carrying
the stem while the other hole beneath is provided to line with the holes provided
in the lug or that beneath the pivotting hole on the third stem J, so that ou
the introduction of the pin R¹ through such holes in line, the fourth stem O" may
assume either an upright position or a position at right angles thereto according
as the hole Q immediately beneath the pivotting hole O or the hole Q¹ in the
lug Q is engaged.
Referring now to Figure 1 a series of positions in which it is possible to place
the holding devices are shown in dotted lines and numbered I, II, III, IV, V, and
it will therefore be seen that in the first place the whole appliance may be adjusted
from its support by means of the worm G and sector F into any inclined position
in one plane while the third and fourth stems J and O may assume a vertical or
an horizontal position on either side from the upper head or socket I of the second
stem E in a plane at right angles to that of the movement of the second stem; and
the fourth stem O" is again capable of assuming two positions relatively to the
third stem E. It will be understood also that if the fourth stem O is turned upon
the head of the third so that its bent extremity is upon the opposite side then
such stem is again capable of assuming two other positions relatively to the third
stem J. It will be seen therefore that it is possible to place the clamping or
holding collars P P¹ in a great number of positions for the greater convenience of
readily assembling and taking apart the various portions of the cycle.
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-
An universal support for use in assembling and taking apart the component
parts of cycles so arranged that the part or parts being operated upon can be held
securely in any determined position substantially as and for the purpose herein-
before described.
