PROVISIONAL SPECIFICATION.
Improvements in Adjustable Supports for Temporary Platforms or
Staging on Inclined Roofs or the like.
I, TOM BATTY, of North View, Drighlington, in the County of York, Decorator,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in adjustable supports for holding
temporary platforms or staging on inclined roofs or the like and its object is to
provide a simple and readily adjustable support of cheap construction.
For this purpose I employ a light angle iron preferably of tee shaped cross-
section to form the base of each support. These base pieces are formed in lengths
or sections and one end of each section is provided with a suitable shaped socket to
fit the plain end of another section which may be secured therein in any convenient
way.
In this manner the base of each support may be made any length required.
An adjustable foot is provided at the bottom to engage the spout or channelling of
the roof or a hook or its equivalent may be attached to engage the ridge of
the roof.
A series of holes are formed on one web of the angle iron to any of which an
adjustable leg also provided with a number of holes may be secured by a thumb
screw or other means. And an approximately horizontal piece is connected at any
required height to this vertical piece and to one of the holes in the angle iron above
by thumb screws or the like.
In use two or more of these supports are employed with their horizontal pieces
connected by a board or boards to form the platform or staging.
The said vertical pieces may be braced together by suitable stays.

Staging on Inclined Roofs or the like.
I, TOM BATTY, of North View, Drighlington, in the County of York,
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 :-

adjustable leg, also provided with a number of holes, may be secured by a thumb
And an approximately horizontal piece is connected at any
required height to this vertical piece and to one of the holes in the angle iron above
by thumb screws or the like.
In use two or more of these supports are employed with their horizontal pieces
connected by a board or boards to form the platform or staging.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specificatiou in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents an elevation of a portion of a greenhouse roof with a plank
or stage thereon mounted on my improved platform support.
Figure 2, represents a plan view of the same.
Figure 3, represents a side view of the same.
Figures 4, 5 and 6 are views of detail hereinafter referred to.
Any number of sections of angle iron may be coupled together to form the base
of the supports A, A but in the drawing three sections A², A³ and A* are shown
for each support, but an exceptionally narrow roof is represented. The sections
are coupled together by the sockets B and secured therein by the thumb screws C
passed through the sides of the sockets and the ends of the sections. The socket
piéces are also provided with lateral lugs B by which they are secured to the
tubular cross pieces D by means of the thumb screws C², C². Figures 4, 5 and 6
represent an end, plan and side view of one of the sockets on a larger scale with
the sections and cross piece connected thereto shown broken away. The cross
pieces D extend across the rafters E and carry the supports clear of the glass. It
is evident they may extend across from one support to the other instead of merely
being sufficiently long to extend over two of the rafters. The supports are
prevented from slipping down the roof either by the foot piece F secured to the
bottom section A' of each support by the thumb screw B passed through one of
the perforations a in the bottom section. This foot piece is adjusted to project into
and bear against the spout G or instead of the foot piece the hook picce F' may
secured in a similar manner to the top section A2 and be hooked over the ridge G²
of the roof.
be
To support the plank or staging H a horizontal bearer J having a forked end j
is secured by a thumb screw B to one of the perforations a in each support and
the other end is supported by the double strut or leg K connected at the lower end
by a thumb screw Be to one of the perforations a and coupled above to the bearer J
by the thumb screw B' passed through one of the perforations a and i formed
respectively in the bearer and strut.
It is obvious that by the arrangement shown a horizontal plank or staging may
be readily and securely mounted upon a roof of any augle and that by bending the
angle iron to the proper form dome and bell shaped roofs may be staged.
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 1
claim is:
1. The combination with the angle iron base of the adjustable bearers J and the
struts or legs K, substantially as herein shown and described and for the purpose
specified.
2. The combination with the adjustable supports of the foot piece adapted to
engage the spout, or the roof piece adapted to engage the ridge of the roof
substantially as herein shown and described.
