PRING CO
with Step-ladders, Tressels, and the like.
We ALLAN EDMONDSON, Cabinet Maker, JOHN BENJAMIN MOORHOUSE, Ironmonger,
and THOMAS ABRAHAM PROCTER, Cabinet Maker, all of Skipton-in-Craven, Yorkshire,
do hereby declare the nature of this invention to be as follows:-
That is, its object is the construction of hinges used in connection with. step-
ladders, etc., in such a manner that by the application of same, the said step-ladders,
etc., are firmly held when opened or in position for use, thus preventing any accidents
by the same suddenly closing.
This said invention consisting of hinging to one or the other of the arms of the
hinge, a bar or secondary arm, which is made to pass through a loop formed on the
opposite arm of the said hinge, the same acting as a guide for it.
On one side or edge of the said bar is formed a notch which lays hold of the part
forming the before named loop when the hinge is in its opened position, the same
being thus rigidly held until the bar is lifted with its notch clear of the part forming
the loop, as will easily be understood.
Again instead of the before named hinged bar passing through a loop, we may
attach a suitably shaped pin to the outer end of it, and form an appropriately shaped
slot lengthwise in the before named opposite arm of the hinge, into which the
said pin may enter loosely so as to move freely therein and in this manner accomplish
the object desired.
Or again instead of employing the above named hinged bar, we form a suitable
projection on the arm of the hinge, in which projection we make an appropriately
shaped segment-slot, on the edge of which in a suitable position we form a notch, so
that a pin, which is passed through the said slot and loosely attached (so that it shall
be rigid in one direction but free and loose to move in the direction at about right
angles to this) to the opposite arm of the hinge, may be placed into this said
notch at which time the hinge would be in its opened position, with the result which
will be clearly seen.

We, ALLAN EDMONDSON, Cabinet Maker, JOHN BENJAMIN MOORHOUSE, Ironmonger,
and THOMAS ABRAHAM PROCTER, Cabinet Maker all of Skipton-in-Craven, Yorkshire
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:
That is to say:
-It consists of the construction of hinges used in connection with
step ladders &c. in such a manner that by the employment thereof the said step-
ladders &c. are firmly held when opened or in position for use, thus preventing any
accidents by the same suddenly closing or being closed. In order that our said
invention may be better understood we have hereunto appended a sheet of drawings
illustrative thereof; wherein figs. 1 and 2 are side elevations of a hinge in its closed
and opened positions respectively, figs. 3, 6 and 4, 7 being similar views, respectively,
of other arrangements for accomplishing same object; while figs. 5 and 8 are detail
sectional drawings, enlarged scale, of parts hereinafter referred to.
The pivot is shewn in section in all the drawings.
This said invention consists of hinging to the arm a of the hinge, a bar or secondary
arm b, which is made to pass through the loop c formed on the other arm d, said
loop c acting as a guide for said bar b. On one side or edge of the said bar bis
formed a notch e (or if desired more than one notch may be formed therein) which
lays hold of the lower part of the loop c when the hinge is in its opened position as
shewn by fig. 2, the said hinge being thus rigidly held until the bar b is lifted with its
notch e clear of the lower part of the loop c when said hinge may be closed as shewn
by fig. 1.
We preferably form the bar b of a curved shape so that when in the position
illustrated by fig. 1 it will not project too far outwardly.
Again instead of the beforenamed hinged bar 6 passing through the loop c, we
may make it straight as illustrated by figs. 3 and 4 (6) and attach the pin to the
outer end thereof, said pin f being made to enter so as to move freely within the slot g
formed in the arm d', said pin fhaving a suitably shaped head h (fig. 5) formed on
the inner end to keep it within said slot, in this manner accomplishing the object
desired.
Or again instead of employing the above named hinged-bar 6 or 6¹, we form a
suitable projection j on the arm a¹ (see figs. 6 and 7), in which projection we make an
appropriately shaped segment-slot k on the edge of which we form a notch / so that a
pin m which is passed through said slot k and loosely attached (so that it will be rigid
when pressed in the direction indicated by the arrow n, or in the opposite direction ;
but be free and loose to move in the direction about right angles to this) to the
arin 'd², may be placed into this said notch at which time the hinge will be in its
opened position as illustrated by fig. 7.; with the result that will clearly be seen.

page_text: In order to allow the pin m to move as above described, the opening for it in the
arm d³ is made lengthwise therein, and a suitable recess is also made to allow for
the moving of the head o when the hinge by its arms a¹ and d are attached to the
step-ladder, tressel etc.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1. The combination of the bar b, having a notch or notches e formed therein, and
the arm a to which said bar bis pivoted; with the loop c and the arm d all arranged
to operate substantially as specified.
2. The combination of the bar 61 having the pin fattached thereto, and the arm a
to which said bar bis pivoted; with the arm d having the slot formed therein, all
arranged to operate substantially as specified.
3. The combination of the arm a¹, having a projection j formed thereon; with the
arm d, and the pin m all arranged to operate substantially as specified.
