PROVISIONAL SPECIFICATION.
Improvements in Window Sashes and Frames,
I JOHN HANSON of No. 2, Charles Street, Bingley, in the County of York,
do hereby declare the nature of this invention to be as follows:-
This invention as applied to carriage windows, will enable the same to be blocked
at any part of the sash, in such a way that there is no rattling or noise through
vibration, and the glass-frame cannot shake down.
This object is accomplished by providing one edge of the window frame with a
corrugated slip, which corresponds in pitch to another corrugated slip, contained by
a metal case and let into the groove of the door style; to this case are attached
inclined springs upon which the loose slip works, in such a manner that when the
window is raised the corrugated slip slides up the inclined springs, thus taking the
grip off the window and allowing it to be raised without friction; but so soon as
the window is stopped, the loose slips drops down the inclined springs and blocks
the window instantaneously.
A lever is provided to let the window down when required.
JOHN HANSON.
COMPLETE SPECIFICATION.
Improvements in Window Sashes and Frames.
I JOHN HANSON of No. 2, Charles Street, Bingley in the County of York
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:-
This invention as applied to carriage windows, will enable the same to be blocked
at any part in the sash, in such a way that there is no rattling, or noise through
vibration, and the glass-frame cannot shake down.
This object is accomplished by providing one edge of the window frame with a
corrugated slip, which corresponds in pitch to another corrugated slip, contained by
a metal case, and let into the groove of the door style. To this case is attached
inclined springs, or wedges, upon which the loose slip works in such a manner, that
when the window is raised, the corrugated slip slides up the inclined springs or
wedges, thus taking the grip off the window and allowing it to be raised without
any friction; but as soon as the window is stopped, the loose slips drops down the
inclined springs, or wedges, and blocks the window instantaneously.
A lever is provided to let the window down when required.
And now in order that this invention may be fully understood I shall proceed
more particularly to describe the same, and for that purpose shall refer to the
Beveral figures on the annexed sheet of drawings by letters of reference.
Fig. 1 is a sectional elevation of door style A, showing the metal case B fixed in
its place by means of screws 7, and containing the loose corrugated slip C, which
may be made to act as a spring-slip as mentioned in my Provisional Specification,
by springs fixed in a similar manner to that shown, so that the inclined portion
will slide upon the stud X; or, in order to obtain a more perfect block, the slip C
may be made in wedge form at those points of contact with the studs, as at X'.
The corrugated slip C is faced with india-rubber and buck-skin or such material as
will stand wear. This facing is fastened to the slip C at each end and indicated
by letter
.

page_text: The glass frame Emay either have its edge corrugated, or a separate corrugated
slip D of metal or hard wood fixed to its edge as shown.
Fig. 2, is another sectional elevation showing the face of the corrugated slip C;
also ornamental lever F. The sectional portions J J indicate the cross rail and
front panel of carriage door.
When the window is raised, the corrugated edge D naturally lifts up the
corrugated slip C, and the inclined portions CX whether springs or wedges, slide
up the studs X, thus taking the grip off the glass frame and allowing it to be raised
without any friction; but as soon as the upward movement of the window is stopped;
the corrugated slip C drops down and grips the glass frame E in the manner shown
at Fig. 1.
The facing of the corrugated slip C with india-rubber and buck-skin combined,
serves as a pliable cushion d between the two corrugated slips C and D and also
prevents any noise, that would otherwise result from the contact of two metal
surfaces.
'
In order to let the window down it is necessary to have a relieving motion,
therefore I have adopted the lever, which may be made ornamental to match the
usual carriage fittings.
The lever F is fixed as shown in Fig. 2, with the short arm underneath the
pin e, so that wlion the lever handle is pulled, the short arm, by means of the
pine which is firmly riveted or screwed into the slip C-raises the slip C and thus
takes the grip off the window and allows it to drop.
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 :-
1st. A corrugated block-action for carriage windows comprising two corrugated
slips, one for the edge of glass frame, the other being faced with rubber & buck-
skin, and fitted with springs or wedges, and contained in a metal case; the whole
being made and constructed substantially the same as described in the foregoing
Specification.
