Improved Means or Apparatus for Preventing кattiing of Kallway
and other Carriage Windows or Shutters.
1 ALFRED GEORGE SPENCER, of No. 77 Cannon Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to appliances adapted to be secured to the edges of
sliding window frames or shutters and to take a bearing in the grooves or channels
in which such window frames or shutters are arranged to slide or travel for opening
or closing.
For these purposes I construct of india rubber or partly of india rubber and partly
of metal, devices as I will now proceed to describe.
In one form my apparatus resembles a ring or perforated block of india rubber,
with projections or parts through which screws or fastenings can be passed to secure
the apparatus to the edge of a window frame or shutter, the ring or block being of a
diameter or width exceeding the width of the groove or channel in which the window
frame or shutter is arranged to slide or travel so that my apparatus shall constantly
take a bearing against the respective sides of such groove or channel and act as an
elastic steadying device or cushion. Or in lieu of being constructed to bear only at
the respective sides of the groove or channel, the apparatus may be constructed with
a part of a hollow hemispherical or like form to bear not only against the sides but
also against that portion of the groove that is opposite to the edge of the window
frame or shutter. Or the device may be of channelled section or in the form of a
block with bifurcated end or ends or outward projections at the respective sides thereof
to bear against the respective sides of the groove or channel or may be of lozenge
shape so as to be secured diagonally in relation to the edge of the window frame or
shutter, in which arrangement the ends of the elastic block will bear against the
respective sides of the groove or channel. To prevent wear of the india rubber owing
to friction small protecting plates or pieces of suitable material such as metal may be
made to adhere to the surface of the india rubber where necessary.

I, ALFRED GEORGE SPENCER, of No. 77 Cannon Street, in the City of London,
Engineer, 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 reference to appliances adapted to be secured to the edges of
sliding window frames or shutters and to take a bearing in the grooves channels or
light runs in which such window frames or shutters are arranged to slide or travel
for opening and closing.
An object of my improvements is to provide means that shall be more durable,
more elastic and shall compensate to a larger extent for wear than devices such as the
solid strips of india rubber heretofore employed with the object of preventing rattling
of windows and shutters.
For these purposes I construct of india rubber or. partly of india rubber and partly
of metal devices such as I will now proceed to describe in which additional elasticity
is afforded by forming them with holes, openings, recesses or channels or a combination
thereof as will be hereafter more fully explained.
In one form my appliance resembles a ring or perforated block of india rubber,
with projections or parts through which screws or fastenings can be passed to secure
the apparatus to the edge of a window frame or shutter, the ring or block being of a
diameter or width exceeding the width of the groove or channel in which the window
frame or shutter is arranged to slide or travel so that my apparatus shall constantly
take a bearing against the respective sides of such groove or channel and act as an
elastic steadying device or cushion. Or in lieu of being constructed to bear only at
the respective sides of the groove or channel the apparatus may be constructed with a
part of a hollow hemispherical or other suitable form to bear not only against the
sides but also against that portion of the groove that is opposite to the edge of the
window frame or shutter. Or the device may be of channelled section or in the form
of a block with bifurcated end or ends or outward projections at the respective sides
thereof to bear against the respective sides of the groove or channel. To prevent
wear of the india rubber owing to friction small projecting plates or pieces of suitable
material such as metal may be made to adhere to the surface of the india rubber
where necessary.
Referring to the annexed sheet of illustrative drawings
Figs. 1 and 2 are two elevations of an appliance according to this invention for
preventing the rattling of railway and other carriage windows or shutters.
Figs. 1 and 2 illustrate the application of this device.
Figs. 3 and 4 are similar views to Figs. 1 and 2 of a modified form of appliance.
Figs. 5 and 6 shew another modification.
Figs. 7 and 8 shew another modification.
Figs. 9 and 10 shew another modification.
Figs. 11, 12 and 13 illustrate another modification.

page_text: Referring to Figs. 1 and 2, A is a block of suitable elastic material such as india
rubber designed to be secured to the edge of the window frame. B, B, are two
plates of metal (it may be brass) cemented or otherwise secured to the edges of the
block to protect them from wear they need not however have flat bearing surfaces as
shewn. C, C, are screw holes. D is a large opening in the centre of the block to
render it more easily compressible. The block is designed to be screwed as illustrated
in Figs. 1 and 2 to the edge of the sliding window frame W to run in the groove or
"light run "V, the faces B, B, rubbing against each side of the groove. To this ond it
will be understood that the device made to be normally of greater width than the
groove channel or "light run" in which it is to travel, so that there will be a certain
amount of compression for which the hole or opening in the clastic block will allow
and thus there will be maintained a constant bearing notwithstanding wear which will
be compensated for. The block shewn in Figs. 3 and 4 has two openings D, D, and
two sets of plates B, B. C, C, are the screw holes. In Figs. 5 and 6 the ends of the
block are bifurcated the projections forming springs at each side of openings D, D.
In Figs. 7 and 8 there are a central opening D, bifurcated ends and three sets of
plates B, B, B.
The block illustrated in Figs. 9 and 10 is constructed to bear not only on the sides
of the groove, but also against its bottom. One face of this block has a convex
form to hear on the bottom of the groove, the required compressibility for this
surface, and also for the edges B, B, being obtained by ineans of the cavity E.
In the modification illustrated in Figs. 11, 12 and 13 the block is of channel shape
with transverse paris A* which however may be dispensed with in some cases. The
cross sectional form of channelled block shewn in Fig. 13 may be varied, for example
it may be curved instead of angular. C, C, are the holes for the screws.
may
be of any suitable length.
The block
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 :-
1. For preventing rattling of railway and other carriage windows or shutters, a
steadying device arranged to be secured to the sliding frame or shutter and consisting
of or comprising a block or piece of elastic material such as india rubber formed
substantially as liereinbefore described with a hole or holes an opening or openings a
recess or recesses or a channel or channels or a combination thereof in such a manner
as to render easily compressible and aid in compensating for wear of parts thereof,
adapted to bear constantly against the sides or bottom or both of the groove or light
run in which the window or shutter is designed to slide.
2. My improved means or appliances hereinabove described with reference
respectively to Figs. 1, 2, 1 and 2, Figs. 3 and 4, Figs. 5 and 6, Figs. 7 and 8.
Figs. 9 and 10 and Figs. 11, 12 and 13 of the drawings annexed for preventing
rattling of railway and other carriage windows or shutters, whether constructed with
or without the plates B.
