COMPLETE SPECIFICATION.
An Improved Self Closing Sash for the Use of Railway Carriages,
Cabs, or Tramcars.
I THOMAS KENNEDY Joiner No. 19 Garnet Street Middlesborough 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 :-
The sash to which the apparatus for self closing is applied is an ordinary one
with styles and rails and works in a groove in the door-frame Fig. 3.
The bottom rail of sash for its entire length is rebated on the outside as at K
Fig. 2. The top edge or shoulder of rebate is bevelled as at J Fig. 2. To this

page_text: At K
bevelled edge is fixed by means of screws a polished metal plate which works
against the bevelled edge of the metal weather bar shewn at 1 Fig. 2.
Fig. 2 in the rebate of bottom rail of sash is fixed a thin strip of indiarubber.
To the styles or side frames of sashi are fitted by means of screws metal plates
notched at intervals as at d Figs. 1 and 2. These plates are sunk level with the
face of the sash.
On the cross rail of door below the bottom of the sash is attached by means of
metal brackets a connecting rod marked F on Figs. 1 and 2.
To this rod and at each end is fixed a catch marked E Figs. 1 and 2. When
the sash is pulled down the catches fall into the notches & Figs. 1 and 2 and the
sash is thus fixed at any point required.
The catches are pressed against the sashes by means of springs as at E Figs. 1
and 2.
To the centre of the connecting rod F. Figs. 1 and 2 is fixed a lever H Fig. 2
which when pressed acts on the piston of lever-catch at G Figs. 1 and 2 and
releases the catch E when the sash slides up.
The sash is drawn up by means of two drums. In each drum is a barrel spring.
These drums marked a, Figs. 1 and 2 are fixed to the top rail of door. A copper
wire cord as at b. Figs. 1 and 2 is attached to each drum and brought down to the
bottom of the sash and fixed there. The drums are grooved and when the sashes
are closed the copper-wires are wound round the drums and lie within the groove.
By the action of the springs the sashes will remain closed. When it is required
to open the sash either partially or entirely pressure must be applied to the sash
lift marked L Figs. 1 and 2.
The sash can be made to remain at any point where the catch E Figs. 1 and 2
falls into any notch in the plate on the side of the sash. When it is required to
raise the sash the lever H Fig. 2 must be depressed and in like manner when the
pressure is removed the sash will remain in the position of that notch which is
nearest the catch E.
Fig. 3 shews styles or side frames of door.
In the groove shewn the sash works.
In the inner small groove the copper
cord 6 works. Over this groove is fixed a cover plate C.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
.
:
The arrangement of the drums for lifting the sash; the covering plates for
protecting the cord and the bevelled weather bar and strip of indiarubber for
stopping draught and clattering.
Dated this 3rd day of October 1893.
