Improvements in Scaffolding.
G
I, PETER PAUL MASSAU of 56, Hohenstaufenring, Cologne on the Rhine in the
Empire of Germany, Decorator 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 improvements in transportable scaffolding and has for
object to provide a scaffold whose dimensions and position can be quickly and
conveniently altered without the plane of the platform being changed so as to be
suitable for use in painting or decorating the interior of houses or rooms and in
which two or preferably all four supports are provided with wheels in order to
facilitate the changing of the position of the scaffold.
I will describe my invention more particularly with reference to the accom-
panying drawings in which:
Fig. 1. shows the improved scaffold in perspective and
Figs. 2-6 are views of parts in detail.
The four vertical supports which or two of which are provided with wheels bare
provided with holes for almost their whole length, said holes being arranged
alternately in cross directions forming right angles to each other, further holes d
bored diagonally being provided at the bottom or lower ends of the supports. The
upper and lower ends of each support are further provided with bands as shown
in Fig. 4. and which are held in position by nails or wood screws. To these bands
are fastened arms g, extending in two directions at right angles to each other, and
forming a support for square stays i connected with same by, and turning on
pivots h. These stays are so connected as to telescope reciprocally with each other
as shown in Figure 1 in such way, that the whole scaffold can be brought into less
compass, said stays being meanwhile held together by clamps as shown in
Figure 2 and which are screwed up when the scaffold has been set in the desired
position by means of the screw pressing against the stay passing through the long
and short shanks of the clamp, the whole scaffold thus being made firm and rigid.
Hooks m (Fig. 6) serve for holding the wooden supports for the planks or standing
platform and of which only one is necessary in ordinary scaffolds. These hooks
are fastened in the holes c of the supports a by means of a screw bolt n at the
desired height, the platform supports being simply laid in same.
When it is desired to alter the dimensions of the scaffold, it is simply necessary
to loosen the clamp screw whereupon the stays i slide over each other and by
drawing together or extending the four corner supports, the scaffold can be made
broader or longer as required. The clamp is again tightened by the screw / and
the scaffold is firm.
In case it be necessary the supports a can also be stayed horizontally by means
of the hook o shown in Fig. 3. These hooks are pushed through the diagonal
holes d of the supports a the horizontal stay being laid in same and clamped
between the supports and the curved part of the hook o by tightening the nut p.
For double scaffolds with six or more supports the bands a (Fig. 5) are used
with four arms g.
These bands are mounted on the middle supports and can each
carry four stays. The double hooks m as shown in Figure 6. are also used for the
platform supports in double scaffolds.
For the purpose of lengthening the supports a their upper ends are provided
with four small angle irons held in position by bands & thus providing a socket
into which the end of the support forming the continuation will be inserted.

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:
upper
An improved transportable slide scaffold consisting of four or more vertical
supports provided at their lower ends with rollers and to each of the and
lower ends of which are pivotally connected two rods having a reciprocal telescopic
movement in diagonal direction and in which the platform supports are made to
rest in hooks which can be placed at any desired height substantially as described
and shown in the drawing.
