and lifted.
Figs. 6, and 7, are sections of Figs. 4, and 5, cut by the perpendicular line X.
Figs. 8, and 9 are front elevations of Fig. 3, showing B respectively fastened and
unfastened.
A is the front plate of the lift. B is the spring, and it should extend either between
the stop beads or the full width of the window, in the form indicated by the parallel
dotted lines seen at the picture Fig. 11. C is a rectangular covering plate
screwed up into B.
D is the back of the lift made in the form of a niche and
riveted on to the back of A. H, H, are the guides that C slides up and down
between, their positions at the back of A are shown by the perpendicular dotted
lines at Figs. 4, and 5. E is B's support. J Fig. 10, is an elevation of the top
edge of the sash stile showing E fixed into it; and I, represented by the dotted
lines, represents a garnish rail that may extend between the stop beads with
E and B fixed into it as shown; it should be screwed on to the inside face of J.
Fig. 2 shows the bottom of E with B passing through it. G is the top rail
of the window. The scale represents six inches. A, C, D, E, and F, are
preferably made of brass. The sizes in the accompanying drawings may be
altered to suit the various requirements. To get the necessary tension at which
to fix B, hold it in the centre, and let each end suspend the window at each
edge of the sash stile, then whatever arch the weight of the window causes B
to make, it should be attached to the window with about half an inch less the said
arch. Whilst thus suspended B's exact length can be taken by marking the width
of the window on it at each end. If it is desirous of placing B between the stop
beads, their width apart should be taken instead of the extreme width of the-
window; as herein before described. When B is lifted up at C, B is drawn away
from F, thus allowing the window to be lifted either up or down, and the instant
C is let go, B springs back again to F thus fastening the window. The surface of
F may be made smooth or as shown in the drawing; and a thumb rest may be
attached to the front plate A above C.
The construction of my combined lift and fastener may be altered in various ways
to that herein before described. The natural form of B may be an arch; and it
may be attached to the window the reverse way to that herein before described.
A, D, and C, may be entirely dispensed with, or altered to any other convenient

other manner not herein inentioned for the purpose herein before described.

Combined Window Lift and Fastener for Railway Carriages, Road.
Vehicles, Ships' Cabins, and the like.
I, ROBERT CLUCAS residing at 16 Claughton Road, Birkenhead, Cheshire,
Joiner, 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 chief object of my invention is to dispense with the straps (and consequent
great expenditure caused through them being so extensively cut and stolen) at
present used to manipulate the window sashes of railway carriages, road vehicles,
ships cabins, and the like, and also to prevent the usual frequent falling and
consequent breaking of the said. windows. But my combined lift and fastener may
be used on all other vertically sliding sashes, or frames such as inquiry and booking
office window shutters, lift doors, and the like.
My invention consists in attaching to and across or partially across the sash
and preferably along the top rail, one length (or various combined lengths of
any suitable and pliable material) of spring steel in an arched or curved direction
so that the versed sine of the arch or curve will increase when the spring is
manipulated at the centre preferably by acting as the lift, that each or either end
or fastener may be consequently drawn from the jambs or racks between which the
sash slides or instantly return when released, preferably as herewith described and
shown with reference to the accompanying drawings.
Figs. 1, and 3, are plaus respectively of my combined lift, and fastener.
Fig. 2 is an underneath view of Fig. 3.
Figs. 4, and 8, are front elevations respectively of Figs. 1, and 3, when acting as
the fastener.
Figs. 5, and 9, are also front elevations respectively of Figs. 1, and 3, when acting
as the lift.
Figs. 6, and 7, are sections respectively of Figs. 4, and 5, cut by the perpendicular
line X.
Fig. 11 is a picture of the top portion of the sash, showing the spring B inserted
which is represented by the curved and parallel dotted lines.
Fig. 10 is an end elevation of the top edge of the sash stile J, and garnish rail I
which may screw on to the top rail of the sash G.
Fig. 15 is the plan of B inserted in I.
Fig. 12 is a front elevation of Fig. 15.
Fig. 13 is a section of Fig. 12 cut by the perpendicular line X.
Fig. 14 is a plan of E which is hereinafterwards explained.
A is a front plate screwed near the top and to the inside face of G or I in
front of the centre of the lift B. B preferably consists of one length of rolled
steel wire, inserted in G or I in an arched or curved manner so that each or
either end will act as a fastener by coming in contact with the jambs or racks
between which the sash slides, and so that the centre will increase in altitude
when acting as the lift, that each or either end may be consequently drawn
free from the said "jambs or racks," or instantly return to the said "jambs or
racks" on being released.
The tension of B should be less than the weight of the window, so that the

page_text: friction which unavoidably takes place in lowering the sash will not cause B to
decrease in altitude until the lift is actually released.
E is.
C is a rectangular covering plate fastened to B to act as the lift. D Sheet I
is a plate made in the form of a niche and fastened to the back of A.
plate preferably screwed to each edge of the sash to support B and also protect the
sash from wearing. F is a toothed rack preferably fastened in the groove of one of
the jambs between which the sash slides. G is the top rail of the sash. H H are
guides for C to slide between, but are only required when F is inserted in each of
the said "jambs." I is a garnish rail fastened to the inside face of G, with
B inserted and fastened at one end the other end being cranked into the groove the-
sash slides in. I may be made any suitable ornamental shape-left long enough.
for general purposes that it may be sawn at the solid end to required lengths.
ACDE and F are preferably made of brass, to suit B when applied as hereinbefore-
described, but B will act and may be manipulated equally as well when suitable.
lignum-vitae racks are used with notches about 1 inch apart and inch deep, and
A and C dispensed with by connecting B with a press button passing through and.
projecting from the bottom of I. The scale represents six inches for the drawings
on Sheet 1 only, and all sizes herein given may be altered to suit requirements.
The construction and application of B may be altered in various ways to that
which has been preferably herein before described-by being made in two separate
lengths-the tension imparted by auxiliary springs or weights or strengthened to
support the sash without using or toothing F any suitable fastener or friction plate.
may be connected at each or either end-or B attached to the sash the reverse way
to that hereinbefore described and manipulated by a latch or spindle, or altered
in any other manner not herein mentioned for the purpose of manipulating the
sash through the increasing and decreasing of the versed sine of the said curve
or arch.
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:
A combined window lift and fastener for railway carriages, road vehicles, ships-
cabins, and the like.
But my invention may be used on all vertically sliding sashes, or frames such as
inquiry and booking office window shutters, lift doors and the like.
The said combined window lift and fastener to consist of one length (or various
combined lengths of any suitable and pliable material) of spring steel, attached to
and extending across or partially across the sash preferably along the top rail in an
arched or curved direction, so that each or either end or fastener will come in
contact with the jambs or racks between which the sash slides, and so that the
versed sine of the said arch (curve, or spring) will increase, so that each or either-
end may be consequently drawn free from the said "jambs or racks" by the said
spring being manipulated at the centre (preferably by increasing in altitude when
acting as the lift as hereinbefore shown B in the accompanying drawings) when the
window is being opened or closed, or instantly return to the said "jambs or racks "."
and again fasten the sash when the said curve or spring is released.
