I GEORGE BOYD THORNTON of 78 Princes Street Edinburgh in the County of
Midlothian Scotland India Rubber Manufacturer, 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 has for its object the prevention of noise and breakage of china
pottery and glass in the shutting of doors, and in the case of glass doors the
removal of their liability to injury by vibration.
And my Invention consists in adapting and applying to the framing of doors a
piece or pieces of rubber tube or rubber cord or suitably shaped piece of rubber
fitted in a metal or wooden sheath or holder fixed on to the framing of the door in
such a manner that the said tube or cord or suitably shaped rubber may be caused
to project from the framing and be capable of receiving the shock occasioned by
the shutting of the door, and by its elasticity on compression allowing the door
to close without noise or dangerous vibration.
°
In the accompanying drawings are represented by way of illustration several
different methods of constructing and applying the improved "door silencer" all
however possessing the same general characteristic of rubber sheathed or contained
in the metal or wooden holder fixed to the framing of the door.
Figures 12 and 3 represent a piece of rubber tube a. sheathed or enclosed in a
metal holder b. with countersunk holes c. c. in its flanges through which it can be
fixed to the framing of the door, such rubber tube a. being fitted on a pin d.
(shewn by dotted lines in Fig. 2) fixed in the sheath or hollow part of the
holder b.
In figures 4. 5 and 6 the rubber tube a. is shewn with a shouldered end and pro-
tected by a metal ferrule e. inserted between the tube and its sheath in order to
adapt it for use with a heavier door.
Fig. 7 represents a door partly open with two "silencers" fixed one at the upper
part, and the other at the lower part of the framing of the door.
Figures 8.9 and 10 shew an arrangement with a piece of solid rubber a. retained by
two pieces of metal f. f. projecting from the interior of the sheath or holder b, which
is also furnished with a kind of spike g. to aid iu fixing it in the framing of the door.

page_text: In figures 11 and 12 is shewn an arrangement of a piece of rubber fitted in a
metal tube h. sliding within the holder b. and thereby compressing a spring i
therein.
Figures 18 and 14 represent a mode of letting the holder into the framing of the
door and fixing it therein so that a portion of the rubber tube alone projects from
the framing.
The foregoing descriptions will serve to illustrate the adaptations of the Invention
to suit its application to doors of different weights and in different situations, but
other variations may be adopted to suit special cases.
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 adaptation and application to the framing of doors of a "door silencer" com-
posed of a rubber tube or rubber cord or suitably shaped piece of rubber enclosed
in a sheath or holder substantially as described.
