PROVISIONAL SPECIFICATION.
Improvements in Knee Rests for use in Scrubbing Floors and other
similar purposes.
I JOHN HARPER of 32 Devon Street Glasgow in the County of Lanark,
Wright do hereby declare the nature of this invention to be as follows:-
:-
My invention relates to the improved construction of knee rests, for the use of
(more particularly) housemaids and others who scrub floors, stairs, and so forth.
It consists of a cork piece, or pieces, or other suitable material, hollowed or moulded
on its upper surface, and in such a manner that the kuees of a user will correspond
or fit into the hollows or moulds formed thereon when in a kneeling position, and
for the object of distributing the weight of the body in a more equable manner over
the surface of the knees. When cork is used it is strengthened by being fixed to a
clamped board of thin wood or other suitable material, the clamps being of sufficient
size, and so situated as to allow the air to freely circulate between the floor and the
rest, and at the same time to protect and keep the cork dry; the said clamps being
also curved on the outer or bottom edges to form rockers (or a board made convex
on its under side only may be used) and for the purpose that the user may more
readily change position, and to prevent the knees getting chafed when moving.
One or more perforations may be formed in the knee moulds for the purposes of
ventilation.

I JOHN HARPER of 32 Devon Street Glasgow, in the County of Lanark,
Wright, 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:-
My invention relates to the improved construction of knee rests, for the use of
(more particularly) housemaids or others who scrub floors, stairs, and so forth.
And in order that my said invention and the manner of performing the same may
be properly understood, I hereunto append a sheet of explanatory drawings to be
hereinafter referred to, and showing a knee rest as made with my improvements.
Figure, 1, of the drawings is a plan view, Figure, 2, is a longitudinal section, and
Figure 3 is an end view.
In these drawings the same reference letters are used to mark the same or like
parts whenever they are repeated.
The knee rest is made of a piece or pieces of cork (or other suitable material)
with hollows, A, A, formed to fit the shape of a users knees when kneeling, and
strengthened by a thin board or veneer of wood, B, to which are fixed the
rockers, C, C, for the purpose of assisting the user to more readily change from one
position to another, and to prevent the knees getting chafed when so doing, the said
rockers also form clamps to prevent the rest from warping. D, is a ring to suspend
or carry rest by. It will be apparent that the dotted line shown in Figure, 3,
represents the shape of hollows, A, A, transversely through centre lines.

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, 1 declare that what I
claim is.
1. The combination of parts forming as a whole my improved construction of a
knee rest substantially as herein before described and as shown in the accompanying
drawings.
2. The construction and adaptation of the hollows, A, A, for holding a user's
knees substantially as hereinbefore described.
3. The application of rockers, C, C, substantially as and for the purpose
hereinbefore described.
