PROVISIONAL SPECIFICATION.
Improvements in or connected with Sashes Provided with Sliding
Windows, Panels, and the like.
I, HENRY GARDNER, of 166 Fleet Street, City of London, Patent Agent, do
hereby declare the nature of this invention which has been communicated to me
from abroad by Matthew Brown, of Woodstock, near Cape-Town, Carriage
Builder, to be as follows:-
This invention relates to certain means and appliances for preventing rattling of
sliding window sashes, panels, shutters, and the like, also to prevent the entry of
dust, and the passage of rain, wind, or draught.
For the purpose of this invention, angle plates are fitted in the grooves in which
the sashes slide, said angle plates being pressed upon by long plate or strip
springs of undulating or wavy form, so that in the case of two sliding sashes being
in the same frame as in houses, they can both be kept from rattling by the same
spring, whether open or closed (one spring being at each side).
Each sash is likewise kept close up to the frame beads for their full length.
The angle plates are carried by bearers, on which they have a transverse
sliding action to compensate for shrinkage, or other climatic changes, and provide
for easy motion of the sashes under every condition.
The invention is specially applicable to the sliding sashes of railway, and
other carriage windows, as no tassels, cords, or other like appliances are required
to hold the sash at any part, the pressure of the springs being sufficient for that
purpose.
It will be understood that the springs are boxed in within the angle plates and
not exposed, and that the sashes slide in contact with the plates.

from abroad by Matthew Brown of Woodstock, near Cape-Town, Carriage

The invention will be the better understood from an examination of the annexed

The invention will be the better understood from an examination of the annexed
drawings.
Figure 1 is a part sectional inside elevation of a carriage door.
Figure 2, a part edge.
Figure 3, perspective elevation of a single angled plate.
Figure 4, perspective elevation of double angle or gutter shaped plate.
Figure 5, perspective elevation of undulatory or wavy shaped spring.
Figure 6, part sectional plan of house sashes with single spring for both upper
and lower sliding coch

page_text: A angle plate fixable in rebate of sliding window sash B. C angle plate to slide
against stile D of sash frame. E spring touching by its bellied parts against both
plates to keep plate C in contact with stile D, with mid-feather F or with sash if
applied as shown for the double or two sash arrangement, Figures 6 and 7.
The anti-rattling and dust excluder invention here described can be arranged in
or to a sliding sash, or to the frame, or to pieces affixable to sash or frame, and to
ensure a proper action of the yielding plate, it can have bearers at intervals to
prevent it dropping or getting out of the square position, or one side can be
arranged to work within or between fixed plate A and an inner frame G such as is
shown at Figure 7, which inner piece may serve as the bearer.
It is preferable that the angle plate or plates be fitted to the sliding sash, but it
may be in the frame for the sash to slide against.
It is found in practice that the wavy like spring is of greater advantage than a
spiral or helical spring for the purpose because of its free elongating action and
the many touching places for ensuring the parallel motion of the yielding plate,
and also from the facility of inserting it without fastenings of any kind. The
spring or springs may be sufficiently strong to hold the sash at any desired
height.
The invention is specially applicable to the sliding sashes of railway and other
carriage windows, as no tassels, cords, or other like appliances are required to
hold the sash at any part, the pressure of the springs being sufficient for that
purpose.
It will be understood that the springs are boxed in within the angle plates and
not exposed, and that the sashes slide in contact with the plates.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The means or appliances substantially as hereinbefore specified for preventing
the rattling of sliding windows, panels, and the like, and for excluding dust, rain,
and draughts, as set forth.
2. The particular arrangement of appliances or devices with an intervening
spring, as illustrated, and fitted in such manner that up and down sliding sashes of
windows or panels can be kept wind and dust proof as herein before described.
