JOHANN CHRISTOTT AUGUST DREMER
Instrasse
Halle on the Saal, Germany, 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:-
The object of this invention is to provide a holder for temporarily fixing frame-
work or supports to iron constructions, the holder from its peculiar form being
capable of application to girders of the most varied shapes, and the fixing of the
holder itself to the girder being effected by simply hanging the one on to the
other.
Moreover, by the arrangement of a rotary carrying arm, the holder is made
capable of being applied in various ways and can be detached without any difficulty.
In the accompanying drawing:-
Fig. 1 is a side view of a holder constructed according to this invention
attached to a large girder.
Fig. 2 a similar view of a holder applied to a smaller girder.
Fig. 3 a front view of the same.
Figs. 4 to illustrate various applications of the holder.
The holder consists of the vertical arm «, furnished at its upper end with a hook
or nose piece b, the inner surface of which is inclined at an obtuse angle to the
arm a and to a supporting arm which runs upwards from the lower part of the
arm a at an acute angle thereto.
Further, in the lower part of the holder, are arms g, in which a carrying arm p
is mounted to rotate (see Figs. 1 to 3).
The attaching of the holder to the girder is effected as follows: The hook or
nose piece is simply laid over the flange, when the fixing is effected by the action
of gravity and the supporting arm which comes below the flange (see Figs. 1
and 2).
Through the hook or nose piece b being at an obtuse angle to the arm, it is
prevented from lying with its whole surface on the flange of the girder and so
being easily broken.
In the same manner owing to the peculiar arrangement of the supporting arm,
in combination with the hook or nose piece the holder becomes more firmly
fixed when laden with the frame work.
Moreover, the movable bearing arm allows of the hook being arranged in any
requisite position as illustrated by way of example in Figs. 4 to 7.
Likewise, the detaching of the hook and removal of the frame work can be
effected thus the bearing arms 22 of the holders preferably arranged alternately
right and left adjoining the plank (see Figs. 4 and 6) or the arched bottom
(see Fig. 7) are simply turned round, so that the plank is released and therewith
the frame-work can fall down.

page_text: 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-
A holder for fixing frame work to iron constructions the distinguishing feature
of which is that the holder is automatically and firmly laid on the girder by the
conjoint action of the hook or nose b, standing at an obtuse angle to the arm a
and that the supporting arm t and the bearing arm p is held movably on the holder
by means of the arms g.
