PROVISIONAL SPECIFICATION.
A Portable Ladder Carriage.
JOHN KELLY Pyrmont House Green Lanes Winchmore Hill Middlesex Cabinet
Maker do hereby declare the nature of this invention to be as follows:-
A portable ladder carriage, consisting of a frame work of wood or iron, hinge
jointed at about one third of its length from the foot end, and a jointed lever fixed
at the side, to raise or lower the frame to any desired angle. This frame is
mounted on two wheels and springs, and a telescope ladder laid upon the frame.
In the event of fire, one man, without any assistance, may immediately run off with
this fire escape, erect it to the windows of the burning building, and save life in
very much less time than is required to bring into action the ponderous machines
now in use.
COMPLETE SPECIFICATION.
A Portable Ladder Carriage.
JOHN KELLY Pyrmont House Green Lanes Winchmore Hill Middlesex Cabinet
Maker 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 improved portable ladder carriage, for quickly raising
long ladders from an horizontal to a vertical position, for general purposes, but
especially for use as fire escapes, which invention, I carry out as follows, and as
described by numbers and drawings herein accompanied.
I employ a frame A either of wood or metal, slightly wider than the ladder to
be raised. The said frame A is hinge jointed at a distance of about five feet from
the lower end, C. Upon this frame a ladder D is laid, and is held in its place by
side guides E at the top, rollers F attached to these guides, side slips G at the lower
end, and the stops H at the extreme lower end. The whole are mounted on a pair
of wheels and springs. At one, or both, sides, as necessity may require, I fix a
jointed hand lever J, and a projecting step K, for foot pressure. To raise the ladder,
the frame is allowed to rest with its lower end on the ground. The operator presses
his foot on the step K, at the same time pulling the lever J, when the frame A
will so far collapse as shown in drawing, and thereby raise the ladder to the position
shown by dotted lines L, in which position the ladder may be used, or, if desired, it
may be placed more perpendicular by the operator placing his fool upon the extreme
end of the frame A and pushing the foot of the ladder against the vertical portion of
the frame, into the position as dotted line M. A chain N is then hooked across the
ladder securing it. The lever J is made secure by passing into the grip O. The
joint P in this lever, is for the purpose of folding it out of the way, when the
apparatus is stored away, either in horizontal, or vertical position. In the latter
case, the lower, or platform end of the frame A is provided with a second joint Q for
the purpose of turning up. The operations of raising and lowering the ladder, are
facilitated by the roller R. The horizontal dotted lines S show the running position
of the whole apparatus.

page_text: 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. An improved portable ladder carriage, with jointed frame, and with levers for
working the same, all as hereinbefore described, and represented in the accompanying
drawings.
2. The combination in an improved portable ladder carriage, constructed, arranged,
and operating substantially as hereinbefore described, set forth, and refered to in
the accompanying drawings.
