Improvements in and relating to Brackets for Ladders.
We, JOHN ALOYSIUS MURPHY, Blacksmith, CHARLES GEORGE POLLEYS,
Stationer, and WILLIAM CHAPMAN SCOTT, Grocer, all citizens of the United
States of America, and residing respectively at 26 Gould Street, 152 Thomas Street
and 42 John Street, in the City of Newport, County of Newport and State of Rhode
Island, one of the United States of America, 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 improvement in brackets for ladders, and it consists
in a bracket which can be made to extend from either side of the ladder, combined
with a curved brace that supports the outer end of the bracket, and a cross piece
provided with hooks to catch over the round of the ladder, and a catch through
hich the lower end of the brace extends, as will be more fully described
hereinafter.
The object of the invention is to provide a bracket which may be made to extend
from either side of the ladder, and upon which bracket a suitable scaffold may be
erected so that workmen may move back and forth upon the bracket in perfect
safety while doing work of any kind upon the side of a house; and to so construct
the brackets that they can be adjusted at any desired angle.
In the accompanying drawings is shown a perspective view of the invention.
A represents an ordinary ladder, and B the bracket applied thereto, and upon
which one end of the scaffold is supported. Each bracket consists of two arms,
pivoted together at their outer ends so as to be adjustable to ladders of different
widths, and which arms are provided with the hooks D at their inner ends to catch
around the two uprights of the ladder just above the round This round of the
ladder serves to support the bracket at its inner end, and to help support one end
of the scaffold. Each bracket extends outward any suitable distance, and is
provided with an upturned end to prevent the scaffold from slipping off from any
cause.
To the outer end of each bracket is pivoted a brace G which serves to support
the bracket in position, and which is provided at its lower end with a series of
perforations by means of which the angle of the bracket and platform or scaffold
can be regulated at will. Secured to the cross piece O is the loop J, through which
the lower end of the brace passes, and through the brace is passed a pin Q, as
shown.
The cross bar extends across the front of the ladder, and is supported in
position by the two hooks Y, which catch over the top of one of the rounds of the
ladder, as shown. The downward pressure of the brace serves to force the cross
bar against the front of the ladder, so that instead of the weight of the scaffold
coming upon the round of the ladder, it is distributed between the two uprights.
These brackets are of course designed to be used in pairs, and the scaffold extends
across between them. By raising or lowering the lower ends of the braces, the
scaffold can be made to set level, or it can be raised at either one of its edges.
Should the inclination of the ladders be considerable, the two brackets may be
reversed upon the ladder and thus made to project from its inner side, and the
scaffold thus be brought nearer to the house.
As will be seen, the bracket and the crossbar are merely hooked over the two
rounds of the ladder, and hence the bracket as a whole, has but to have its four

page_text: hooks disengaged, and then it can be adjusted higher or lower upon the ladder, or
applied upon the opposite side.
Having now particularly described and ascertained the nature of our
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1. A ladder bracket, consisting of a bracket which is hooked at its inner end upon
the two uprights of the ladder, combined with an adjustable brace for supporting the
outer end of the bracket, and a cross bar provided with hooks for catching over
the round of the ladder, and provided with means for holding the lower end of the
brace, substantially as shown.
2. A bracket for supporting the end of a scaffold upon the end of a ladder,
consisting of the two hooked arms for catching upon the two uprights, combined
with a brace, and a cross bar which is applied to the side of the ladder, the cross
bar being provided with means to suspend it from one of the rounds of the ladder
and means for engaging with the lower end of the brace, substantially as described.
3. The bracket provided with hooks at its inner end to catch over the edges of
the uprights of the ladder, and just above one of the rounds, combined with a
brace G, that is connected at its upper end to the outer portion of the bracket, and
the cross bar O, which bears against the edges of the uprights, and is provided with
the hooks V, for catching over one of the rounds of the ladder, and a loop through
which the lower end of the brace passes, substantially as set forth.
