COMPLETE SPECIFICATION.
An Apparatus for Holding Cycles whilst the same are being
Put Together.
I, FRIEDRICH LAUENROTH of 16 Geiststrasse, Halle a/S in the Empire of
Germany, Mechanical Instrument Maker, 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. :-
In building up or putting together cycles, as also in making any necessary
repairs, it is requisite to arrange the machine in such a position and to hold the
same firmly in said position in such a manner that every part is readily accessible
and can be removed or replaced when desired. Obviously the machine will be
held and supported at those places or parts which are strong enough for the
purpose, whilst the centre of gravity of the whole should be selected so as to ensure
stability in every direction. For this purpose the diagonal stays or members of
the cycle frame are primarily most suitable and will be arranged to be held by the.
cycle holder proper. The latter is in turn arranged so as to be capable of motion
in all directions in the framing or stand supporting the same. The construction of.
the said framing or stand may be variously modified.
In the accompanying drawing:
Figure 1 is a diagrammatic view of the cycle holder.
Figures 2 and 3 illustrate details, and
Figure 4 is a broken view in section showing another mode of mounting the
cycle holder.
Throughout the views similar parts are marked with like letters of reference.
For the purpose of receiving the diagonal struts or members there serve angle
irons H, H, which are pivotted to a strap or clip G at h and ', so that they can
be adjusted to suit the dimensions of the cycle frame. The cycle is fixed in
position by means of a second angle iron K which is pressed against the holder H
in the following manner :-
On the strap G, the mode of attaching which will presently be described, there
is arranged a rotary eye m in which works a screw k that presses the pressing
piece K against the hind diagonal stay; this said piece K being enabled to adapt
itself to the inclination of this stay in each particular case.
For the purpose.
of
its attachment the strap G is provided on its rear side with two lugs g, gl which
are adapted to be fixed to the shaft E by means of the screw bolt R, the said
shaft E being capable of movement in the framing or stand. The shaft E is
formed at its forward end with a flat head with two noses f, fl. The head is bored
through at 1. By this construction the holder, and with it the cycle, can be set to.
any desired inclined position.
In the vertical position shown in Figure 1, the nose f¹ prevents any further
rotation of the strap G about the pivot or bolt R. The horizontal position of the
plane of the cycle is produced by means of a pin or stud which is inserted through
or into the corresponding holes in the strap and the holes in the head of the
shalt. The pin S is made elastic or springy as in the manner shown in Figure 2,
so as to prevent it from falling out when the holder is rotated.
""
By providing a number of holes in the head of the shaft, any desired number
of positions can be obtained intermediate between the end positions of the cycle
determined by the noses f and f¹.

page_text: The shaft E may be fixed in different ways. In Figure 1 it is held by means
of a stand constructed after the manner of a pillar. Figure 4 shows a method
of fixing it to the work bench, for which purpose it is mounted in a suitable
bracket.
The pillar B stands on the base plate A which must either be of sufficient
weight to obviate tipping over, or be bolted down to the floor. The other end of
the pillar is constructed in the form of a bearing D which is adapted to be moved
in a vertical direction by means of a screw band to be moved in a horizontal
direction by means of a screw d. A dish C is provided for the purpose of
receiving the necessary tools; this dish is arranged on the shaft of the pillar and
is adapted to be adjusted to any desired height by means of a set screw c. This
dish will of course be dispensed with in those cases. where the holder is fixed to
the work bench.
It is obvious that by means of the screws provided at every joint, the cycle can
be brought into any desired position and be fixed in such position.
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 :-
(1.) The improved apparatus for holding cycles for, construction or repairs,
substantially as hereinbefore described.
(2.) A stand for building and holding cycles, consisting essentially of the
supports or bearing parts H, H', and K adapted to receive the diagonal stays and
arranged to adjust themselves automatically to the parts of the frame they are
intended to hold, of the strap or clip G to which the supports or bearing parts H, H¹
and K are pivotted, of a horizontally movable and rotatable arm E having a
suitably formed head or bearing to which the strap or clip G is fastened, and of
the stand B with base A, as and for the purpose set forth.
