page_text: EUGENE FERRARI of 19 Claverton Street, South Belgravia London in the
County of Middlesex, Portmanteau Maker, do hereby declare the nature of this
invention to be as follows:―
The ladder of my Invention is so constructed as to be capable of being used in a
variety of positions to which Ladders as ordinarily constructed are not readily
applicable. In the form in which I preferably construct the ladder two short
ladders are hinged together at one end. They can be used as an ordinary step
ladder or locked in a straight line to form a continuous ladder. At the bottom
end of the ladder I attach in a suitable manner a short leg or legs which can be
folded up when the ladder is required for ordinary purposes and which when
locked in position makes one side of the ladder longer than the other so that it
can be used on staircases etc.

page_text: EUGENE FERRARI of 19 Claverton Street South Belgravia London in the
County of Middlesex Portmanteau Maker, do hereby declare the nature of my said
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The ladder of my invention is so constructed as to be capable of being used in a
variety of positions to which Ladders as ordinarily constructed are not readily
applicable. In the form in which I preferably construct the ladder two short
ladders are hinged together at one end. They can be used as an ordinary step
ladder or locked in a straight line to form a continuous ladder-At the bottom of
the ladder I attach in a suitable manner a short leg or legs which can be folded up
when the ladder is required for ordinary purposes and which when locked in
position make one side of the ladder longer than the other so that it can be used
on staircases &c.
The ladder as shewn in the accompanying Drawing is constructed almost entirely
of wood but it may be made of any material or materials possessing the requisite
rigidity The hinge may be of metal and metal plates for the thumbscrews to
screw into may be inserted into or form part of the sides.
In the accompanying drawing the same letters indicate the same parts.
Figures 1. 2 and 3 shew the ladder arranged for use as a stepladder.
Figures 4 and 5 shew the ladder arranged for use as a continuous ladder.
Figure 1. is a view of the ladder arranged as a stepladder for ordinary purposes.
The two portions A and A¹ are hinged together at B in such a manner as to allow
their being folded up parallel to each other.
Lugs C are formed on both sides of A, so that when the ladder is extended they
bear against the extensions A² of portion A and are secured thereto .by thumb-"
screws passing through hole C¹.
Four legs E. E¹ E2 E3 are pivotted to the sides of the latter at e. e¹ e² ea. The
legs E. E are shewn attached to the opposite portion of ladder A¹ to lock the
halves apart. The legs E E³ not being in use are attached to sides of ladders.
Figure 2 shews the ladder with legs E² E³ extended, the legs E. E' are utilised
for locking the halves of ladder apart.
Figure 3. shews the ladder with legs E¹ E' extended, the leg E is used for
locking the halves of ladder apart.
Figure 4. shews the ladder extended and locked together forming a continuous
ladder. The legs E. E E E³ are not in use and are folded up and attached to
sides of ladder.
Figure 5, shews the ladder extended as in fig. 4 but with leg E extended, and
legs E E E³ folded up.
The legs E. E E E³ are locked or fastened in their various positions by thumb
screws which fit into holes h and h¹ on legs and sides of ladder, the extra holes /³
are provided so that the length of extension of legs may be varied to suit.
It is evident that these legs may be applied to any form of ladder.

page_text: Having now described and illustrated my invention I wish it to be understood
that I do not confine myself to the exact details shewn and described but what
I declare that I claim is
The extensions or legs, applicable to any form of ladder substantially as shewn
and described.
The general combination of two ladders hinged together and provided with a leg
or legs for the purposes set forth and substantially as shewn and described.
