COMPLETE SPECIFICATION.
An Improved Means of Stationary Transmission of Power at any
Desired Angle and Level with Safety from Fire.
I, ADOLPH STRIEMER of 8, Mohrenstrasse, Berlin in the Empire of Germany,
Merchant, 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 more particularly to the arrangement of a stationary
means of transmitting power by means of which, without any consideration of the
angular position or lever of the transmitting shafts, rotation may be conveyed in,
through, or between chambers entirely shut off from one another so that any
danger of fire is avoided as the usual belt tubes hitherto employed are dispensed with
and the danger and insecurity connected with the usual belt or rope driving is
obviated.
This invention also renders it possible to carry out stationary transmission of
power in such a way as is necessary for the most advantageous utilisation of space,
as the stationary transmission may now be brought into any angular position
without loss of power and is no longer impeded by columns, pillars, ceiling joists
or the like standing in the way.
In the accompanying drawings:-
Figure 1 shows the arrangement of a means of transmission in which the trans-
ference of the rotation from one shaft to another is effected within chambers shut
off or separated from one another in such a way as to be impervious to fire,
Figure 2 showing the means of effecting a similar arrangement but outside the
building,
Figures 2 and 3 further show suitable ways of carrying out the transmission
which is no longer impeded either by its angular positions or different levels or
by supports, columns, posts, joists or the like standing in the way.
As is apparent from the drawings, the straight stretches of the stationary trans-
mission are formed, in the usual manner, of rigid non-flexible shafts. At the ends
or rather between each two ends of the same there is arranged where necessary,
a flexible shaft b. The shaft connection from one stage to another, immaterially
whether in a vertical or diagonal position, takes place in such a way that here
also the straight stretch is formed in the ordinary manner by a rigid shaft t', whilst
the ends of the shafts are each suitably connected by the ends of a flexible
shaft b. The vertical or diagonal shaft is held ly a suitable bearing such for
instance as a c d a c and c². In order to avoid friction, the upper or lower bear-
ing, such for instance as a q¹ or c cd, may be made as a ball bearing. The
openings for the passage through the walls or ceilings are closed, as shown for
instance in Figure 1, by the bearings dc c², so that the continuation of the trans-
mission from one stage to another is not only effected without the use of belts or
cords but essentially in a fire resisting manner by avoiding the belt tubes hitherto
employed, as the passages or openings are closed by the bearings and any danger
is thus excluded and the safety of working assisted.
A furthur advantage of this arrangement consists further in that, for instance in

page_text: the arrangement shown in Figures 2 and 3, the means of transmission are no
longer impeded by projecting supports y, beams or the like, or by the trans-
mission shafts being arranged at different levels. As in order to get round the
former or into or round the corners they may be equalised by setting them at
various heights. The latter not only helps to render the fixing more stable and
everywhere equidistant from the floor or ceiling, but it assists also to remove the
friction of shafts mounted eccentrically to one another.
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 arrangement of a fire-resisting stationary means of transmission, character-
ised by the rigid parts of the shafting (t ) being carried by means of suitable
bearings (a c c d al c¹), which close the passages or apertures (o), and by the said
rigid parts of the shafting being connected in a suitable manner with one another
by means of flexible shafts (b), with the object of enabling the rotation to be
transmitted into or between separate and fire-resisting closed chambers without
the use of belts, ropes, belt shafts or the like, substantially as described.
2. In means for stationary transmission such as described, the arrangement
of flexible shafts (b) which are suitably connected with the rigid parts of the shaft-
ing (t) in such a way that by means of the flexible shafts the conveyance of the
rotation may take place at any suitable angle or level without the use of belts,
ropes or the like, substantially as described.
