page_text: I, FREDERICK HEYWOOD, trading as Thomas Tabberner and Company, of 1
and 3, Southgate, Manchester, in the County of Lancaster, Merchant, do hereby
declare the nature of this invention to be as follows:--
This invention relates to door stops which are screwed to the floor to prevent a
door from being opened too far.
Hitherto such stops have usually been made of hard wood, or of vulcanized
rubber which in time becomes as hard as wood, and the object of my invention is
to provide a door stop which will be soft and noiseless and will remain so, and
also will be very cheap to manufacture.
The invention consists of a door stop formed by moulding around a suitable
core of wood or other hard and cheap material a cushion composed of a mixture of
suitable gelatine or glue and glycerine.
The gelatine or glue is dissolved in a suitable quantity of hot water and the
solution is mixed with about an equal amount of glycerine or more or less glycerine
may be used according to requirements. This mixture will be in the first place
a thick viscid fluid which can be poured or run into a mould in the centre of
which the wooden or other core is fixed, and on cooling the mixture will set in
this mould in the form of a soft elastic annular mass or cushion, adhering to the
core which is preferably provided with circumferential grooves or flanges or other
projecting parts which assist adhesion to the inner surface of the annular cushion.

I, FREDERICK HEYWOOD, trading as Thomas Tabberner and Company, of 1
and 3, Southgate, Manchester, in the County of Lancaster, Merchant, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following state-
ment:-
This invention relates to door stops which are screwed to the floor to prevent a
door from being opened too far.
Ilitherto such stops have usually been made of hard wood, or of vulcanized
rubber which in time becomes as hard as wood, and the object of my invention is

page_text: to provide a door stop which will be soft and noiseless and will remain so, and
also will be very cheap to manufacture.
The manner in which my said invention is to be performed or carried into
practical effect will be readily understood on reference to the sheet of drawings
hereunto annexed and the following explanation thereof.
Fig. 1 is a side elevation, Fig. 2 a vertical section, Fig. 3 a plan view, and
Fig. 4 a horizontal section of one form of my improved doorstop. Fig. 5 is an
elevation and Fig. 6 a vertical section of a modification of the same.
The invention see Figs. 1, 2, 3 and 4 consists of a door stop formed by moulding
around a suitable core a of wood or other hard and cheap material a cushion
of a mixture of suitable gelatine or glue and glycerine.
The gelatine or glue is dissolved in a suitable quantity of hot water and the
solution is mixed with about an equal amount of glycerine, or more or less
glycerine may be used according to requirements. This mixture will be in the
first place a thick viscid fluid which can be poured or run into a mould in the
centre of which the wooden or other core a is fixed, and on cooling the mixture will
set in this mould in the form of a soft elastic annular mass or cushion adhering
to the core a which is preferably provided with circumferential grooves or flanges
see Fig. 2 or other projecting parts which assist adhesion to the inner surface of
the annular cushion.
Sometimes I make the core a of a plain cylindrical form (see Figs. 5 and 6)
and I cover the top of the same with a thin plate or disc of brass c of larger
diameter, and I encase the bottom of the same in a similar thin brass shoe d and
I unite the discs together by means of wire rivets e passing through the core a.
I may mention that glucose or molasses may be substituted for glycerine, but
as it would not be so durable I prefer the latter.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
The improved doorstop consisting in the combination of a core of wood or other
suitable cheap material of an external cushion composed of gelatine or glue and
glycerine and either with or without an upper and lower disc of thin brass sub-
stantially as hereinbefore described and illustrated by the drawings annexed.
Dated this 16th day of March 1899.
