Rosswein, Saxony, in the Empire of Germany, Bicycle maker and engineer.
I, ALFRED JULIUS BOULT, of 111 Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an adjustable support for cycles, which is the only oue
enabling a cycle to be completely fitted up (to the last part) and the wheels to be
centred and finished thereon. The standard provides for secure holding by enabl-
ing both the frame-tubes to be grasped, and also, it is not necessary to squeeze
them very hard so that weak frame tubes are not bent.
A machine can be fixed in the standard in different ways and also can be turned
and inclined to any side.
When the cycle is fixed in the pivotted and adjustable holders and it is desired
to turn it to one side, it is only necessary to slightly withdraw a spring holt from
a joint between the top and bottom parts of the standard, and the cycle can
be laid horizontally, the closing bolt returning automatically into its position.
Before laying the machine horizontally, the set screws on the pivotted holders
must be tightened to prevent the cycle from turning.
For repairing-shops and cycle-works the standard is an indispensable article,
as any fault in the machine fixed in it must be seen, and it is extremely easy to
work on it without having to stoop or to work on the floor.
When laying the machine horizontally, the standard is to be turned in the tripod
which supports it so that the machine is laid in the direction of one foot of the
tripod whereby overturning of the standard is prevented and the necessity of
screwing the standard to the floor is avoided. Should the machine have to be
cleaned on the other side, the set screws of the holders are loosened and the
machine is turned on the standard on to the other side and in this way all dirt can
be quickly and efficiently removed.
The base of the apparatus is preferably a tripod with a plate for laying down
tools upon. On the standard is the socket of a ball and socket joint in which the
ballhead is pivotted and can be fixed by a spring-controlled bolt.
Above the joint is a rod hereinafter termed the upper rod which can be adjusted
n any direction about the ball and socket joint and secured on it are two sleeves
called "cross-sleeves" i.e. each one comprises two sleeves pivotted to each other.
Rods which are adjustable in the cross-sleeves can be fixed by set screws and carry
slotted springy holders or clamps which can be tightened on the frame-tubes by
screws and which are preferably lined inside with some soft material.
There is another "cross-sleeve" on the upper rod i.e. the rod above the ball-
joint in it is an adjustable rod having a head with a bore-hole in it and carrying

page_text: in the bore-hole a cranked rod for centreing the wheels pivotting in the hole in
the head. A sleeve adjustable on the centreing rod carries a centreing-point
which touchs the tyre of the revolving wheel. There are sleeves on the centreing-
rod and upper rod the recesses of which hold the hub between them during the
centreing.

Improvements in or relating to Adjustable Supports for Cycles.
I, ALFRED JULIUS BOULT, of 111 Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, 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 support or stand for holding a cycle or parts of the
same whilst under construction or repair or whilst the wheels of the same are being
centred. The object of the invention is to facilitate the construction and repair
of cycles by the provision of an adjustable support which will allow of the workinan
standing upright and which will render any faults of construction readily obser-
able and the general examination of cycles more convenient and easy.
In the accompanying drawing Figs. 1 to 4 are perspective views of the support
(of this invention) in different positions for practical use in the construction or
repair of cycles. The remaining figures refer to details of construction.
a is the foot of the support, 6 an upright fixed in the foot a, e an arm jointed
to the upright at the semispherical ends d by means of a screw bolt f and nutg
so that the arme may be turned latterly on the upper semispherical end of the
upright b, c are clamping jaws (Figs. 5, (i, 7) one fixed to or in one piece with the
rod, the other turning on a pivot m and operated to engage or release the frame
parts of a cycle by means of a screw n. The rod is arranged to slide and be
adjustable in the portion y of a slide bracket (Figs 5, 6, 8) which is carried by its
other apertured portion on the arm e. The bracket is furnished with two set
screws s one for fixing it on the arm e and the other for fixing the rod 7, and thereby
the clamping jaws in any desired position. is a spring stud serving to lock the
arm in the desired position on the upright & for which purpose said arm, is pro-
vided with a number of holes i (Fig. 10) any one of which may be brought to
register with the end of the spring stud which will then spring into it and fix the
arm in the corresponding position (Fig. 9). is a knob or handle by which the
stud is released against the resistance of its spring.
7 is a spring fixed between the two jaws e and tending to open or keep them open
(Fig. 7) thus, when the screw is unscrewed, facilitating the withdrawal of the
frame parts. The jaws e may be covered on their gripping surfaces with india
rubber or wood o but as two pairs of jaws are provided on each support for holding
a cycle (Figs. 1, 2, 3) they need not be locked very tightly.
The arrangement for centreing the wheels comprises an adjustable slide bracket
having two portions t, u, apertured at right angles to one another as in the
bracket, a rod adjustable and capable of being fixed by means of the
screw in the portion of said bracket and formed with an apertured spherical
head an angular rod y which at one end is adjustable in the head and fixed
therein by means of a set screw ; two slide rings 1, 2 (Figs. 11, 12) adjustable
respectively on the arm and rod y and capable of being fixed thereon by set

page_text: screws 3, 4; and a centring spindle 5 adjustable in the part 7 of the small cross
apertured bracket 6, 7 (Figs. 13, 14) the part 6 of which is adjustable on the angular
rod y and may be fixed by a set screw S.
The slide rings 1, 2, have each a recess or bore 9 in which is placed the end
of the axle of the wheel to be centred (Fig. 3) and which serves as a bearing for
the axle in the centreing operation whilst the spindle 5 is adjusted to a position.
close to the wheel rim and serves for trueing up the same.
The plate or tray 10 carried on the upright serves for the reception of tools or
cycle parts.
It is obvious that the above described support for use in the construction,
repair and examination of cycles may be readily adjusted, without special tools
to any desired positions suitable for the particular work in hand.
Having now particularly described and ascertained the nature of said inven-
tion, as communicated to me by my foreign correspondent and in what manner
the same is to be performed, I declare that what I claim is:-
A support for use in constructing, repairing and overhauling cycles and in
centring the wheels of the same, comprising a stand having jointed to it an
adjustable arm c which may be rigidly fixed in position by means of a stud h;
clamping jaws e for holding frame parts of cycles and capable of adjustment
relatively to the arm e by means of cross apertured slide brackets q, r; a rod w
with apertured head a, arranged to be adjustable in a cross apertured slide
bracket carried on the arme an angular rod y adjustable in the head
rod w; slide rings 1, 2, with recesses or bores 9 for the reception of the axle ends
of wheels to be centred and a cross apertured slide bracket 6, 7, mounted on the
angular rod y and carrying an adjustable spindle or stud 5 for use in centring
wheels, substantially as and for the purpose described and illustrated in the
accompanying drawing.
