TAILL
An Improved Means or Holder for Fixing Scaffold Poles.
I, HERMANN TOBLER of Mayenfeld in the Republic of Switzerland but formerly
of Deli, East Coast of Sumatra, Dutch Indies, Engineer, 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 an improved means or holder for fixing scaffold poles,
that is to say, a device for connecting to a certain extent the cross members with
the uprights running past them. This scaffold pole holder consists essentially of
two or more side pieces or bars either formed in one piece with a solid centre piece
or connected together by suitable means, said holder having teeth or claws so
arranged as to grip on the one side the oue scaffold pole (for instance, the upright
member), and on the other side the other scaffold pole (for instance the cross
or horizontal member) the necessary space being left for the round shape of the
wood.
In the accompanying drawings,
Figures and 2 show in elevation and plan respectively, partly in section,
a form of construction of the scaffold pole holder connecting the poles; and
Figures 3 and 4 show similar views of another form of construction;
Figure 5 represents a vertical section through the middle of the scaffold pole
holder in the form of construction shown in Figures 3 and 4.
Figure 1 shows a side elevation of the scaffold pole holder with the horizontal
member 6 in vertical section, whilst a represents the upright member. Figure 2
shows a plan of this from below, a horizontal section being taken through the
upright member. The scaffold pole holder C is provided at the sides with teeth c
and is suitably formed to provide sufficient space to admit the round shape of the
wood as at for the horizontal member and as at a¹ for the upright member. The
centre part of the scaffold pole holder is preferably formed by the pins or posts c¹
but the rest of it is cut out. The sides of the scaffold pole holder, which carry the
teeth c, arc extended towards the side of the horizontal member in order to
simultaneously act as a support for the said member. These side projections are
connected by means of the post c³.
This scaffold pole holder may be used alone for connecting the horizontal
member with the upright member. As a precaution, however, it is advisable to employ
another safety fastening, if even a small one, such as a cord, withe or the like (2)
which is fastened round in any suitable manner.
Figures 3 and 4 show as already mentioned a further form of construction of
the scaffold pole bolder with means for connecting to the round wood; a being the
upright and the horizontal member. In this case the longitudinal sides of the
scaffold pole holder are connected by means of a full or solid centre piece C",

page_text: Figure 5, which on each flat side is curved cylindrically, one side approximately
corresponding to the upright member to which it is to be fitted, and the other side
to the horizontal member to which it is to be fitted.
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. An improved means or holder for fixing scaffold poles, consisting of a suitably
shaped device, the edges, bars or sides of which are provided with points, teeth or
claws (c) for gripping or engaging with and holding fast the poles substantially as
described.
2. In a device of the kind described the arrangement of the teeth or claws (c)
in such a way as to render them capable of gripping or engaging in both an upright
member and a cross or horizontal member substantially as described.
3. In a device of the kind described the formation of the toothed sides on a solid
plate in one piece therewith (Figures 3 and 4) substantially as described.
4. A device of the kind described having toothed side plates (C) connected
together by posts (cc) (Figures 1 and 2) substantially as described.
5. A device of the kind described having its sides (C) extended downwards and
outwards for the purpose of providing a support for the cross or horizontal member
(Figures 1 and 2) substantially as described.
