Improvements in Temporary Scaffolding for Painting Walls, Cleaning
Windows, and the like.
I, ALFRED EARP JONES of 17, Walton Park, Walton, in the County of
Lancaster, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention is based essentially on the principle of a tie and strut connected
by a chain or its equivalent in such manner as to enable the tie to become a rigid
platform.
In adapting my invention for a temporary scaffolding for painting walls, I place
two ladders or long planks with holes in them or other vertical or oblique support.
Hooking out of each of these ladders is the tie consisting preferably of a bar or
two bars with a cross piece at the end projecting behind the ladder or other
support. Hinged to this tie bar at the other end is the strut which preferably
consists in this case of one or two bars having a cross piece at their other end.
This cross piece bears against the ladder or support. A chain connecting a point
of this strut and passing through a hole on the tie bar to a hook, or attached to the
tie bar with an adjustable attachment completes the supports for the platform.
The platform then is placed on these two bars heretofore called the tie bars.
When the apparatus is used for cleaning windows, the bar heretofore called the tie
bar is made very broad so as to act also as the platform instead of having to have
a platform laid on it. There can however be two of these bars and a platform laid
on them. If however the one be used as a platform it is supplied with a couple of
rings into which a cross piece is passed long enough to hold on each side of the
window. This cross bar has preferably knobs on the end and fits into hooks on
the window jambs, but it is obvious that any method whatsoever of anchoring the
end of the tie bar or platform in the room such as for instance a cross bar fixed to
the platform would produce the same result. In speaking of a chain connecting
the strut and the tie piece, it is obvious that links with differential attachment long
screws hinged to the one and passing through a nut in the other and the like could
be used instead of a chain, and that the chain can be clipped or held in any con-
renient manner. The platform railings are preferably hinged to the platform and
are armed with hinged columns fitting into holes or links or eyes or other attachments
in the platform. By these means the entire apparatus can be folded flat for
transport and can be immediately rigged in place when required. The tie pieces
when not used as platforms have a curb on the end to hold the platform in
position.

page_text: in such a manner as to enable the tie to become a rigid platform, being the same in
both cases.
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 combination of a horizontal tie bar having a hinged flap L, bracket M,
hook G and pulley F with a strut hinged to the tie bar, and a chain or its
equivalent fixed at one end to the strut, its other end passing over the pulley F to
the hook G substantially as and for the purposes set forth.
2. The combination with horizontal tie bars supporting a platform of railings
hinged to such tie bars and suitably stayed, whereby while the railings are held
firmly in an upright position they can also be readily folded for transport.
3. The combination of a tie bar A, a strut C hinged thereto, a chain or its
equivalent by which the strut is suspended, a pulley F, over which the chain passes
to a hook G, a hinged flap L, brackets M, railings hinged to the tie bars, and
stays J and K for the purposes described.
4. The combination of a horizontal tie bar having a curb at one end and a cross
piece at the other, with a strut hinged at one end to the tie rod and having a cross
piece at the other, both cross pieces being bent at their extremities to clip, one at
the front and the other at the back of a ladder or other support and a chain
connecting the inclined strut with the horizontal tie bar for the purposes set
forth.
