An Improved Scaffold and Means for Attaching same to a Ladder.
I EDWARD PARTRIDGE of Senior Street, Dewsbury, in the County of York,
Foreman 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 :-
The nature of my invention is to hold a board firmly at the back of a ladder, in
a horizontal position, one end being attached to a stave and the other end being
borne by a chain which is fastened to the ladder nearly at the top, to secure the end
of the scaffold board to the ladder, four plates are fastened to the board one at each
side at the top, a Fig. 1 and one at each side underneath 6 Fig. 1 the plates project.
a sufficient distance from the end of the board to rest firmly on the stave, the two
top plates are straight but the two bottom ones are bent down a little making the
distance between the top and bottom plates greater at the ends than it is where
they are fastened to the board, which makes it grip the stave firmly, a chain goes
round the.frame of the ladder at each side just below the stave on which the board
rests, the chain has a hook, d Fig. 3 at each end, and in the middle a ring e Fig. 3
where the end of the long chain Fig. 3 is joined to it, after passing the ends of the
chain round the frame of the ladder, the hooks d. d. are put into the ring e Fig. 1,
the long chain goes lengthwise under the board and after passing through a notch
which is cut in the end of the board is taken to the top of the ladder where it is
secured to a hook Fig. 2 which hangs in the centre at the back of the ladder, this
hook with ring is in the centre of another chain Fig. 2. which goes round the frame
of the ladder at the top and is also secured by putting the hooks h. into the ring i
Fig. 2.
If the ladder stave should break on which the board is fixed a pin j passes

page_text: through the board edgewise and prevents the board from being pushed end foremost
through the ladder.
To put the scaffold on to the ladder it is carried up to the height required and hung
on a stave by the hook k, the two branch chains are fastened round the ladder
frame just below the stave where the board is to be fixed, the chain Fig. 2 is taken
to the top or any suitable distance, the hook g hanging in the centre, the long chain
is then hung on hook g, the scaffold is then unhooked and put in a horizontal
