PROVISIONAL SPECIFICATION.
A Combined Check or Buffer and Draught Excluder for Doors,
Casements, and the like.
I, JAMES SANDY, Joiner, c/o Charles John Newbury, Builder, Contractor, &c.,
Hook-with-Warsash, near Titchfield, in the County of Hampshire, do hereby
declare the nature of this invention to be as follows:-
-
My invention relates to a device or apparatus to be affixed to the top or side jams
of inside or outside doors, casements and the like, and adapted to serve the double
purpose of a stop or buffer for preventing such doors, casements or the like from
being slammed or shut with great force, and for excluding draughts or air currents
between such doors or the like, and the jams against which they do or should abut
when shut.
My invention consists of a strip of wood (moulded or otherwise) of suitable
dimensions which I screw or otherwise fix upon either the upper or side jams of
a door, casement lattice or the like, the said strip having formed upon its under and
outer face a suitable recess or rabbet, in which slides laterally a second strip or
tonque of wood or other material, the latter being connected to the former by the
means of suitable springs, the tension or expansive force of which serve to push
the said tonque out of the said groove or rabbet, the said springs being compressed
by the door or the like (when closed) abutting against the said tonque and forcing
this into its groove or rabbet, the said tonque thus serving the double purpose of a
stop or buffer when closing the door or the like, and a draught excluder while
the door or the like remains so closed.

A Combined Check or Buffer and Draught Excluder for Doors,
Casements, and the like.
I, JAMES SANDY, Joiner, c/o C. J. Newbury, Builder, etc., Hook-with-Warsal,
near Titchfield, in the County of Hampshire, 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:-
…….. malátna to a device or annaratus to be affixed to the top or side jams

page_text: of fusive of outside doors, casements and the like, and adapted to serve the double
purpose of a stop or buffer for preventing such doors, casements or the like, from
being slammed or shut with great force, and for excluding draughts or air currents,
between such doors or the like, and the jams against which they do or should abut
when closed.
In order that my said invention and the manner of its application and use for
the purposes stated
may be fully understood, I have hereunto appended a sheet of
drawings, of which,
Fig. 1 is a perspective view of a portion of the device forming the subject matter
of my invention...
*
Fig. 2 is a part sectional view of a door or casement frame with the door partly
open, shewing the application of my invention to the top of the said frame, while
Fig. 3 is a like view with the door closed.
Fig. 4 is a similar section of a door or casement frame looking upwards,
shewing the application of my invention to one of the sides of the frame thereof,
Fig. 5 being an enlarged cross sectional view of my said invention as I may find
it convenient to arrange it when employed as at Fig. 4.
My invention consists of a strip of wood or other suitable material A, moulded
or otherwise, and of such length as to correspond with the width or length of the
door of the frame to which it is to be applied, and such a strip I arrange to
form, and take the place of, or be screwed or otherwise fixed upon the existing
jams of the frame B of a door or casement, and in the accompanying drawings I
have assumed the former arrangement as adopted. The said strip A has formed
upon its outer face a suitable recess or deep rabbet or rebate C, for the whole of
its length, and in this place a strip or tonque D; of wood or other material,
of the same length as the said rabbet and adapted to slide laterally therein, and
be retained in position by a suitable number of spiral or other springs E,
placed at a convenient distance apart, along the length of the said rabbet or
recess, and each connected to the said strip or tonque D, and the strip A,
the tension or expansive force of the said springs operating to force the
strip or tonque D in an outward direction from the said recess or rabbet. A
strip and tonque or constructed, and being of a length equalling that of the width
of the door F, I place and fix as stated upon the upper and horizontal portion of the
frame B, in such a manner that the outer edge of the tonque D presses against the
door F, so that as the latter is closed this forces back the said tonque into the recess
or abbet C as at Fig. 3, against the tension of the springs E, the tonque 1 thus
serving as a check or buffer to prevent slamming of the door, and to exclude
draughts or air currents passing between D and F when the latter is so closed, the said
tonque being forced outwardly from C by the spring E as the door F is opened as
at Fig. 2, and in order that the sudden impact between F and D when closing the
former, may not be audible, and that F when so closed may be more intimately
connected with D, I provide and fix by any suitable means upon the outer edge
of D a facing G of rubber, cloth, leather or other resilient material.
For the same purposes the sides of the frame B are provided in like manner
with similar strips and tonques as shewn in Fig. 4, which operate in precisely the
same way when opening and closing the door, but in so far as relates to the inner
jam, or that upon the side of the frame B to which the door is hinged, in order that the
tonque D at this side may not leave the rabbet for such a distance as to obstruct
the closing of the door, I may provide a groove or its equivalent H in the rabbet C,
in which may slide a plate or strip J, fixed upon the back face of 1), as at Fig. 5,
which serves to limit the outward movements of I) as therein shewn, and with the
same object in view I may form a chamfer K upon the door F as shewn in Fig. 4.
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:-
-
In an improved device or apparatus for silencing the closing of doors, and for

page_text: excluding draughts and air currents when so closed, the construction, use, and
application of strips such as A, fixed upon the existing jams of a door frame B,
or in place of such jams, the said strips having each a rebate or rabbet C in which
slide tonques D, retained in position by springs E, and with or without having
facing G of resilent material, and stops such as J moving in grooves such as H,
connected and operating substantially as herein described and shewn by the
accompanying drawings.
Dated this 28th day of October 1898.
