City of Westminster, Engineer do hereby declare the nature of this Invention to
be as follows:-
My Invention relates to improvements in the device for retaining railway carriage
and other window-sashes at any required height for which I obtained previous
Letters Patent dated the 24th day of January 1885 and numbered 1033. My
present improvements have for their object to simplify the construction and working
of the device, so as to enable the window sash to be raised, and to be lowered.
slowly and without shock by the use of one hand, and with greater ease than as
previously arranged. My present improvements consist essentially in reversing the
arrangement of the parts, and otherwise modifying their operation; that is to say;
it consists in mounting the gripping lever on the sash instead of on the garnish
rail of the door, and in fixing the rib (to be gripped by the jaw of said lever) on
the door instead of on the sash. In carrying out my Improvements, I mount the
gripping lever to work on a fulcrum carried by the sash into the top cross rail of
which the lever would preferably be boxed, the thumb piece at the tail end of said
lever being at, or near, the centre-line of the sash. The said thumb piece, whereby
the lever is released, may be in addition to, or in lieu of, or combined with, the
ordinary sash-lift, and the lever may be made self-engaging by the action of gravity
alone, or aided by a spring, as the case may be. The jaw of said lever is con
stituted by an open slot or notch and the rib which it is adapted to engage with,
may be a plain strip of metal screwed to the stile of the door, and forming a flange
projecting into the groove in which the sash slides.
Owing to the situation of the lever at the top of the sash, the jaw does not
become wholly free of the rib or flange when the sash is lifted outwards over the
fence rail.
In case of breakage of the lever at the slot or jaw, the pressure of the remaining
side of the slot against the rib would still sustain the sash.

'I EDWARD JACOB HILL of 6 Westminster Chambers, Victoria Street in the City
of Westminster, 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 relates to an improved device for retaining railway-carriage and
other window sashes at any required height. The device is simple, and the sash
may be easily raised, and may, if desired, be lifted outwards over the fence rail (if
any), and the sash may be lowered slowly and without shock by the use of one
hand. The device consists of a gripping lever, mounted on the sash, and formed
with a gripping jaw which embraces and grips a vertical rib on the door stile; the 1
thumb-piece by which said lever is operated being generally, but not necessarily,
combined with the ordinary sash lift as hereafter described.
Reference is to be had to the accompanying drawings forming a part of this
Specification in which figure 1 is an inside view of part of a railway carriage-door
and sash provided with my device, Figure 2 is a vertical section of the sash and
door showing the sash raised and lifted over the fence-rail. Figure 3 shows on n
larger scale an outside face view of the gripping lever with the cover removed.
Figure 4 is an inside face view of the same, shewing how the cover is shaped to fit
over the lever, and showing also how the lever grips the rod Figure 5 is a sectional
plan of same. Figure 6. is a similar view to figure 4 showing the lever not gripping
the rod. Figure 7 is a cross section of a door-stile showing an alternative mode
of fixing the rib thereto. Figures 8. 9. and 10 shew a modification. The same
letters of reference indicate the same parts in all the figures.
Referring to figures 1 to 7 a is the gripping lever fitted to the top-rail.b of the
window-sash, the lever working on a fulcrum at about the middle of its length.
The one end of this lever projects into one of the grooves o in which the sash works
and is formed with a head having a gap or notch d in it in such a position as to
embrace a metal rib or flange e fixed to the stile of the door and projecting into
the said groove o, the plane of the rib being perpendicular to the plane of the sash.
The stile 6 of the sash is rebated or grooved, as at 6 in figure 7, to clear the rib
and has a gap or notch cut in it, as at 6 figure 3; to allow room for the end of the
lever to play up and down. The notch d in the end of lever a is free to slide upon
the rib so long as the jaws or faces at each side of the notch are parallel to the rib
as in figure 6, but immediately the jaws assume the oblique position relatively to
the rib shown in figure 4, they grip the rib firmly and so sustain the sash at the
desired height. The lever a is pivoted between fulcra at f in a metal box fixed to
the outer face of the top rail b of the sash, and the inner or tail end of the lever is
usually situated at the middle of the width of the sash and terminates in a thumb-
piece g which passes through a slot in the cross-rail 6 of the sash and projects from
the inner face thereof, the slot limiting the extent of angular motion of the lever a
This thumb-piece is, preferably, combined with the ordinary sash-lift h for which
purpose the latter has an aperture at h¹ to permit of the thumb-piece working up
and down within it. A spring i fixed to the fulcrum box, and, pressing on the tail

page_text: end of the lever, tends always to throw the jaw-end into its position of gripping
engagement with the vertical rib e, as shown in figure 4. The lever is boxed in by
a cover k applied to the outer face of the rail b.
In the normal position of the lever the thumb piece y projects below the sash
lift h as in figure 4 in such a position that in the act of gripping the sash lift
between the finger and thumb the thumb piece will be pressed upwards, as in
figure 6, thus disengaging the jaws of the lever from the ribs and permitting of
the free up and down motion of the sash, the jaws of the lever remaining dis-
engaged so long as the lever is retained in this position. All that is necessary
therefore in order to release the sash is to attempt to raise the sash by means of
the sash lift h' in the ordinary way, no special operation being necessary to release
the lever the weight of the sash when the lever is released being borne by the sash
lift. Immediately the thumb-piece is released the spring i tends to throw the
lever into the position shewn in figure 4 and the jaws assuming an oblique position
with regard to the rib e, grip it and thus at once arrest the descent of the sash.
The lever is thus self-engaging. As shown in figure 2 the sash when fully raised
may be lifted outwards over the fence rail z if desired, without disconnecting the
jaws of the lever a from the rib e.
The rib e may either be a plain strip of metal clamped by a bead or fillet Z
screwed to the stile of the door as in figure 5 or it may be a piece of Langle iron
or brass screwed to a bead or fillet which is screwed to the door-stile as in figure 7.
The spring i might be dispensed with the lever in that case acting by gravity but
it is preferred to use the spring to ensure the instantaneous action.
Referring to figures 89 and 10, the principle is the same and the construction is
similar except that the lever is shorter and is independent of the sash lift h, two
hands being required to raise or lower the sash in this case, instead of one hand
as before. In this case, the lever is mounted on the inner side of the sash and the
ribe is fixed towards the outer side of the door, the notch d being correspondingly
arranged, the relative position of the parts thus being the reverse of that in the
former arrangement. In this case, if the spring i be omitted, the device will not
be self engaging but must be moved by the hand into position of engagement by
pressing down the thumb piece.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed; I declare that what
I claim is;
1. A device for retaining railway carriage and other windows consisting of a
lever pivoted on the window sash and formed with a notch or slot at its outer end,
in combination with a rib or flange fixed alongside the sash groove in a plane
perpendicular to the plane of the lever, the notch being adapted to embrace and
to slide upon said rib and to grip the same in the manner and under the conditions
described, substantially as specified.
2. A device for retaining railway-carriage and other window sashes consisting
of a lever pivoted on the top rail of the window sash and capable of limited motion
on its fulcrum, and formed with a notched outer end adapted to embrace a rib
projecting into the sash groove in a plane perpendicular to the plane of the lever,
the tail end of the lever being formed with a thumb piece in juxtaposition with
the ordinary sash-lift for combined use in the manner described.
