PROVISIONAL SPECIFICATION.
Apparatus for Facilitating the Raising of Long Ladders.
AUGUSTUS HAGHE, of 33 Binfield Road Clapham London, S.W. Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
I fix a light trestle of wood or iron braced with wire ropes to the ladder at a point
somewhat above its centre of gravity in such a manner as to allow of free vertical
movement. To the foot of the ladder I secure a small specially constructed winch
the rope froin which is led to the feet of the trestle. I now slightly raise the ladder
& working the winch, draw the foot towards the trestle thus causing the ladder to
take a vertical position.
In some cases owing to obstacles the trestles cannot be used. I then make the foot
of the ladder into a trestle by fixing a sill thereto and making stays of wire rope or
iron rods. I fix a strut to the ladder in the same manner as the trestle was in
previous case and arranging winch to pull on foot of strut thrust the ladder upward
by its motion.
I further modify to meet certain conditions by fixing foot of ladder into a saddle
hinged to one end of a pole or angle iron laid along the ground, which saddle is forced
into a vertical position by means of a strut actuated by a long screw: or a shoe
takes foot of ladder from which a strut rises from the top of strut a rope is led on one
side to a point some distance up ladder; & a flat band, chain, or rope on the
other side to a winch fixed at the end of pole or angle bar laying along the
ground.
To more fully explain my Invention I hereto annex certain drawings.

COMPLETE SPECIFICATION.
Apparatus for Facilitating the Raising of Long Ladders.
AUGUSTUS HAGHE of 33 Binfield Road, Clapham London S.W. Civil Engineer
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 has for its object to facilitate the raising of any long ladder. The
letters of reference occurring in the following description of my invention refer to
corresponding letters on the drawings filed with my Provisional Specification and may
be seen on reference thereto.
To carry out such invention I fix a light trestle, made either of wood or iron, to the
ladder which is braced thereto with wire ropes or stays at a point somewhat above
its centre of gravity, and in such a manner as to allow of the free vertical movement
thereof; while to the foot of the ladder 1 fit a suitable winch, the rope from which is
led to the feet of the trestle. The ladder is then slightly raised and by working the
winch the foot thereof is driven towards the trestle thus causing the ladder to take a
vertical position. This arrangement is shewn in plan and side elevation in
Figs. 1 and 2 of the drawings above referred to. Lis the ladder. P are the poles or
light iron tubes which with the braces or stays T form the trestle. Care clips by
means whereof the position of the trestle can be regulated. R is the rope working
round a winch W, which is driven by a worm wheel. H is the point of connection
between the trestle and ladder.
S is a light support which can be removed when the
strain is taken by the rope R.
In cases where owing to want of space or from any other cause the trestle cannot
be used, I convert the foot of the ladder itself into a trestle, by fixing a cill thereto
and fitting the same with suitable stays, made either of wire, rope, or iron rods; while
I fix a strut to the ladder in a similar manner as the trestle above described, and
arrange the winch to pull on the foot of such strut and so raise the ladder. This
arrangement is shewn in plan and elevation in Figs. 3 and 4 of the drawings above
referred to. In these figures the trestle is shewn as being formed by fitting the
ladder L with a cill O, which may be either of wood or iron, and with guys or stays T.
H is the point of connection. K the strut. N the roller or wheel for easing it along
the ground. M the pulley for taking the strain on the rope R. This pulley acts as a
guide to the wheel N. S the support and W the winch.
A further modification of my invention consists in fitting the foot of the ladder with
a saddle which is hinged to one end of a pole or angle iron laid along the ground.
The saddle is raised into a vertical position by means of a strut operated by a screw
working in a socket and actuated by bevel gearing. Or a shoe may be fitted to the
foot of the ladder which shoe is provided with a vertical strut from the top of which a
rope is led on one side to a point some distance up the ladder and a flat band chain or
rope on the other side to a winch fitted at the end of the pole or angle iron.
Figs. 5 and 6 shew views in side elevation of these modifications.
In Fig. 5 A is a saddle into which the foot of the ladder is fixed. B is a polo or
angle iron which is laid along the ground. K is the strut. N is the wheel or roller
travelling along the pole B. D the screw working in a socket E which on being
operated by the bevel gearing at F draws the wheel or roller N along, thus raising the
saddle and the ladder into a vertical position. Or instead of the screw. Dan hydraulic
cylinder may be employed. The ladder is steadied by means of suitable stays as shewn

page_text: in Fig. 3. In Fig. 6 G is a shoe into which the foot of the ladder L is fixed.
U is a
vertical strut rising therefrom. R the rope connecting the top of the strut with an
eye on the ladder L. V is a steel band or flat wire rope connecting the top of the
strut with a winch W fitted at the end of the horizontal pole or angle iron B. When
the winch W is turned the strain traverses the ropes V and R and exerts a lifting
strain on the ladder at h. The band or flat rope V as it is coiled on the winch rides
upon itself and the line of pull therefore remains central.
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. For raising a ladder the apparatus substantially as hereinbefore described and
shewn at Figs. 1 and 2 of the drawings.
2. For raising a ladder the apparatus substantially as hereinbefore described and
shewn at Figs. 3 and 4 of the drawings.
3. For raising a ladder the apparatus substantially as hereinbefore described and

4. For raising a ladder the apparatus substantially as hereinbefore described and
shewn at Fig. 6 of the drawings.
