JOHN GLENDENNING, Salesman of Thorpe Hamlet Cottage Norwich and WILLIAM
COOR PARKER Esqr. of Green Park, Darlington, Gentleman 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:-
Our invention consists of an improved method of adjusting the height of Foot-
stools and other stools.
In the accompanying drawings
Fig. 1 represents the Stool in perspective, having a portion broken away.
Fig. 2 represents a vertical section of the same.
The letters in both drawings represent corresponding parts viz.
"a" the Base-plate.
""the vertical standard attached to *
side.
"c" the movable Foot-board.
"d" the Husk attached to "c."
E the Pawl engaging the ratchet.
a " and having a ratchet face on the inner
It will be seen by reference to Fig. 1 that the movable Foot-board is firmly held to
and supported on the Standard "b" by the weight of the Board forcing the Pawl E
into one of the teeth of the ratchet while the top part of the Husk is firmly pressed
against the Standard at "dd." By the above arrangement it will be seen that c. E. d,
form a lever, and that the greater the weight on "c" the more secure it will be.
In Fig. 2 the Board is shewn tilted, thus disengaging the Pawl "E" from its ratchet,
and allowing it to be moved in an upward or downward direction.
As soon as the Board is permitted to return to its previous position it is reset.
It must be understood that although preferably adopting the form of Ratchet and
Pawl shewn in these drawings, we may use any modification of it, for instance holes
and pin, as herein after described. Thus in the place of the Ratchet on the Vertical
Standard, we provide a Standard having a number of holes vertically arranged and we
also provide a corresponding pin or stud on the Husk to fit into the said holes.

We wish it to be clearly understood that we do not claim as a novelty the use of a
Ratchet and Pawl arrangement as applied to the adjustment of Foot-stools, this being
well known and in use in Dentists and other chairs which have Foot-rests attached
such Foot-rests however are not independent but require the chair as a portion of their
support and they also require the assistance of tightening screws or springs to force
the Pawl against the Ratchet.
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
First. An independent and portable Foot-stool having a movable Foot-board which
Foot-board is attached to a vertical standard or standards by means of a Husk or
clip to each standard and adjustable at given heights by means of a Ratchet and Pawl,
in which the impinging force holding the Pawl to its Ratchet is obtained through the
weight and leverage of the movable Board; substantially as described.
Secondly. An independent and portable Foot stool having a movable Foot-board,
which Foot board is attached to a vertical standard or standards by means of a Husk
or clip to each standard and adjustable vertically upon the standard or standards in
which the impinging force holding the Foot rest to the standard or standards is
obtained through the weight and leverage of the movable Board substantially as
described.
