Complete Specification Accepted, 30th Nov., 1888
I, OTTOMAR ERFURTH, Master Mason, of Teuchern, Germany, do hereby declare the
nature of my invention to be as follows:-
My invention relates to metallic holders or temporary supports for securing
horizontal wooden beams to vertical main posts, such as are used in the erection of
buildings. The improved holder is adapted not only to support the horizontal beam,
but also to fix itself' automatically to the vertical post or pole.
It comprises a curved upper arm or saddle projecting over the front of the post, a
horse-shoe-piece joined to the lower end of the said saddle arm and extending around
the back of the beam, the inner side of this horse-shoe-piece being armed with a spur
which enters the back of the post; a triangular lower arm or counter piece extending
downward from the upper arm and partly surrounding the wooden post from the front,
said counter piece being provided at the bottom with a spur which enters the wooden
post from the front.
The upper arm or saddle piece is preferably made in duplicate, that is to say, one
being at each end of the horse-shoe-piece. The holder thus constitutes a frame
having at the top a single or double saddle, at the back a spur and at the bottom a
second spur.

page_text: I, OTTOMAR ERFURTH, Master Mason, of Teuchern, Germany, do hereby declare the
nature of my invention and in what manner the same may be performed, to be
particularly described in and by the following statement :-
My invention relates to metallic holders or temporary supports for securing
horizontal wooden beams to vertical main posts, such as are used in the erection of
buildings. The improved holder is adapted, not only to support the horizontal beam,
but also to fix itself automatically to the vertical post or pole.
In the accompanying drawings Fig. 1, is a side elevation of a scaffold holder in use.
Fig. 2, is a front elevation, Fig. 3, a plan and Fig. 4 a vertical section of the same.
Fig. 5, shows a scaffold holder in the act of being applied to a vertical post.
Fig. 6, shows the same after it has embraced the post, but before it is fixed to the
same.
The holder is made of one piece having an upper arm or saddle A for supporting the
horizontal beam, and a circumferential arm or clamp B which forms the continuation
of the saddle arm and extends around the post. This arm B is armed with a spur a
which enters the wooden post D from the back and prevents the holder from sliding
along the same. From the saddle arm A extends downward a lower arm or counter
piece E which encloses the post D from the front and two sides and is likewise pro-
vided with a spur b. If the beam F is placed on the saddle arm F, its weight will
tend to press the holder against the column D, in such a manner, that the spur on
one side and the counter spur & on the other side will both enter the wood and
prevent the holder from sliding off.
As shown by Fig. 5, the holder can be easily applied to any scaffolding post
from the side, and fixed at the desired height by driving in the spurs with blows of a
hammer.
Fig. 6, shows the position of the holder in which it may be caused to slide up and
down along the column.
Having now particularly described my invention and in what manner the same is to
be performed, I declare that I claim,
1. A scaffold holder composed of a saddle arm, a clamp armed with a spur and
a counter-arm armed with à spur, the whole arranged and adapted to operate sub-
stantially as described.
2. A scaffold holder, consisting of saddle arm A, clamp provided with spur a, and
counter arm E provided with spur 6, all made of one piece and arranged in the
manner substantially as described.
Dated this 27th day of October 1888.
