Machinist and FRANCIS SANDERS MORRIS of Middleton Lodge, Tottenham in the
county of Middlesex, Engineer do hereby declare the nature of the said invention
for "IMPROVEMENTS IN AND APPLICABLE TO THE SASHES OF RAILWAY AND OTHER
CARRIAGE DOORS AND WINDOWS AND SLIDING SASHES OF ALL KINDS
to be as
follows:-
33.
Our invention relates to improvements in and applicable to the sashes of railway
and other carriage doors and windows and sliding sashes of all kinds the object of
the invention being to provide improved means whereby such sashes can be raised
and lowered with great ease and facility and without the necessity of having to
carry the sash over a weather strip the sash moving in a direct line with the pit or
hollow of the door.
In carrying out our invention as applied to a carriage door we employ a weight
acting as a brake upon the sash or window and keeping it in position which weight
or break can be released by suitable means such as a lever from either side or both
sides of the window.
•
The sash is hung similarly to ordinary sliding sashes that is to say, by means of
two weights which slide up and down one on either side of the sash, these weights
together weigh a little more than the window so as to overbalance the same and
the lever by releasing the first described weight or break allows the side weights to
act upon the window and elevate it to the required position.
It is advantageous that the said side weights be arranged to slide up and down
in grooves cut in the moulding or beading forming the finish to the door or
framework.
For use with carriage and like sliding sashes we construct what we call a
tumbling weather board by which means we avoid the necessity of pushing sliding
sashes or windows over weather strips and thereby greatly facilitate the lowering
of the sashes.
The tumbling weather board moves up and down with the window or sash to
which it is applied and is attached to the bottom of the sash by suitable means

page_text: such as by means of lugs with holes in which work the extremities of the weather
board knife edge or the like. Our weather board is preferably of feather section
the thick edge being outside thus always tending to fall forward by virtue of its
weight or the weather board may be weighted.
The weather board folds or turns up when the sash or window to which it is
applied is depressed and is lowered with it, but falls forward upon the ledge of the
frame immediately the sash or window is fully elevated.
The sash or window can be raised from the outside by means of a lug which
allows the operator to elevate the weight and put the side balances or weights in
action.
Amongst the advantages of this invention one of the most important is that we
are enabled to entirely dispense with the use of springs of all kinds. We can
accomplish the elevation and depression of the sliding sash or window either from
within or without in a simple and efficient manner.
Our improvements can be applied to existing railway carriages or the like, for
the purpose of automatically raising the sash by using the strap which is at present
on the sash and of the roller over which the strap:passes; at the free end of the
strap we attach a weight which can slide up and down in a case which we fix in
the centre of the panel of the door; the herein before described brake can then be
adapted to the sash so as to operate from the inside or the outside as will be well
understood, the sash would not as hitherto pass over the usual weather strip but
would be provided with our improved tumbling: weather.board..

page_text: Improvements in and Applicable to the Sashes of Railway and
other Carriage Doors and Windows and Sliding Sashes of all
kinds.
We JOHN EATON of Swallow Street, Stockport in the county of Chester
Machinist and FRANCIS SANDERS MORRIS of Middleton Lodge, Tottenham in the
county of Middlesex, 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:-
Our invention relates to improvements in and applicable to the sashes of railway
and other carriage doors and windows and sliding sashes of all kinds the object of
the invention being to provide improved means whereby such sashes can be raised
and lowered with great ease and facility and without the necessity of having to
carry the sash over a weather strip, the sash moving in a vertical groove in a direct
line with the pit or hollow of the door.
In carrying out our Invention as applied to a carriage door we employ a weight
or a spring operating a break upon the sash or window and keeping it in position
which weight spring or break can be released by suitable means such as a lever or
projection from either side or both sides of the window.
The sash is hung similarly to ordinary sliding sashes, that is to say, by means of
two weights which slide up and down one on either side of the sash; these weights
together weigh more than the window so as to overbalance the same and the lever
by releasing the first described weight spring or break allows the side weights to
act upon the window and elevate it to the required position.
It is advantageous that the said side weights be arranged to slide up and down
in grooves cut in the moulding or beading forming the finish to the door or
framework.
For use with carriage and like sliding sashes we construct what we call a
tumbling weather board by which means we avoid the necessity of pushing sliding
sashes or windows over weather strips and thereby greatly facilitate the lowering
of the sashes as they are always ready for direct depression.
The tumbling weather board moves up and down with the window or sash to
which it is applied and is attached to the bottom of the sash by suitable means
such as by means of lugs with holes in which work the extremities of the weatlier
board, knife edge or the like. Our weather board is preferably of feather section
the thick edge being outside thus always tending to fall forward by virtue of its
weight, or the weather board may be weighted.
The weather board folds or turns up when the sash or window to which it is
applied is depressed and is lowered with it, but falls forward upon the ledge of the
frame immediately the sash or window is fully elevated.
The sash or window can be. raised from the outside by means of a lug or pro-
jection which allows the operator to elevate the weight or operate the spring and
put the side balances or weights in action.

page_text: Amongst the advantages of this invention may be mentioned that we can
accomplish the elevation and depression of the sliding sash or window either from
within or without in a simple and efficient manner.
Our improvements can be applied to existing railway carriages or the like, for
the purpose of automatically raising the sash by using the strap which is at present
on the sash and the roller over which the strap passes; at the free end of the strap
we attach a, weight which can slide up and down in a case which we fix in the
centre of the panel of the door; the herein before described brake can then be
adapted to the sash so as to operate from the inside or the outside as will be well
understood; the sash would not as hitherto pass over the usual weather strip but
would be provided with our improved tumbling weather board.
In order to enable our invention to be fully understood we will proceed to
describe the same by reference to the accompanying drawing in which figure 1, is
an elevation of the inner side of a railway carriage door shewing our invention
applied to the sliding sash of the same which is shown in its raised position a
weight being employed for actuating the break; figure 2, is a vertical transverse
section; and figure 3, is a horizontal section on line A, B, of figure 1; figure 4 is a
similar view to figure 1, but shewing the sliding sash in its lowered position; figure 5,
is an elevation of part of the outer side of the door; figure 6 is a vertical transverse
section of part of the door drawn to a larger scale; figure 7, is a similar view to
figure 2, but shewing a spring for actuating the break; figure 8 is a vertical trans-
verse section shewing our improvements applied to an existing railway carriage
door. Similar letters in all the figures represent similar or corresponding parts.
Referring to, figures 1 to 5, a, represents the weight jointed at b to the lever c,
having lateral extensions.d, which carry at their ends projections e, pivotted at f,
to the frame g, of the door and bearing upon the face of the sash h, and thereby
forming the break ;'i, i, are the weights, one on each side of the sash which weights
together weigh more than the window so as to overbalance the same; j, j, are the
cords or lines to which the lower ends of the weights i, are attached and by which
the sash is hung the said cords passing. over sheaves or pullies k, in a similar manner
to ordinary sliding sashes; the weights i, are arranged to slide up and down in
grooves, cut in the moulding or beading m, forming the finish to the door or
framework as clearly shewn in figure 3; the weight a, is contained in the pit or
hollow of the door and is provided at its lower end with a projection n, passing
through a slot or hole o, in the outer casing of the door and serving to raise the
weight a, and thereby operate the break from the outside of the door; p, is a guide
for the weight a.
q, is the tumbling weather board which is pivotted to the bottom of the sliding
sash h, by means of lugs r, at each end working on pins 8, on the sash; when the
sash is raised the tumbling weather board q, rests in an inclined position upon the.
ledge t, of the door frame as shewn in figures 2 and 6 and is formed as shewn of a
feather section the thick edge being outside so that it will always tend to fall
forward by virtue of its weight; when the sash h, is lowered the weather board q,
is caused by the ledge t, to fold or turn up on the pivots or pins 8, and will pass
(with the sash) in a vertical position into the pit or hollow of the door; as will be
seen by reference to figure 2 the sash h, moves in a groove u, in a direct vertical line
with the pit or hollow of the door and by the use of the tumbling weather board q,
the necessity is avoided of pushing the sash h, over the usual weather strip which
is therefore dispensed with and the lowering of the sash is greatly facilitated.
By this construction the sliding sash h, being in its raised position as shewn in
figures 1 and 2 when it is required to lower the sash it is only necessary to press it
downwards by means of the usual lug v, at the top of the sash when the weather
board g, will as hereinbefore described be turned on its pivots 8, and will pass with
the sash into the pit or hollow of the door; the weights i, are at the same time
raised into the position shewn in figure 4 and the sash will. be prevented from.being
raised by the weights, by reason of the pressure of the projections. or break e, a,
pressing upon the face of the sash. In order to raise the window it is simply

page_text: necessary to lift the weight a, by means of the lever c, at the inner side of the door
or by means of the projection n, at the outer side thereof so as to release the sash
from the pressure of the break e, e, when the weights i, i, will overbalance the sash
and raise it; the weather board q, will then tumble or fall forward onto the ledge t,
as shewn in figures 1, 2, 5 and 6.
The arrangement shewn in figure 7 is the same as that herein before described
and illustrated in figures 1 to 6 with the exception that a spring a, is employed for
actuating the break e, e; the said spring serves by bearing against a guide p¹, fixed
to the door frame and against a shoulder w, on a rod a¹, jointed to the lever c, to
depress the said rod and thereby produce the required pressure upon the break
by tension; the projection n, for releasing the break consists of a lever having
its fulcrum at ax, and jointed to the rod a¹ at y; in order to release the break
from the outside of the carriage the lever n, is depressed and the operation will
then be substantially the same as that hereinbefore described with reference to
figures 1 to 6.
In figure 8, which illustrates our improvements applied to an existing railway
carriage door, j, represents the strap with which the sash h, is usually provided and k,
is the roller over which the strap j, passes; i, is the weight which we attach to the
end of the strap j, and m, is the case which we fix in the centre of the panel of the
door and in which the weight i, slides up and down; it will be observed that
the strap j, roller k, and weight i, serve a like purpose to the cordsj, sheaves or
pulleys, and weights i, respectively hereinbefore described and shewn in figures 1
to 7; the rest of the parts are similar to those shewn in the said figures and the
operation will be understood without further description.
It will be obvious that our improved tumbling weather board is applicable to
other kinds of sliding sashes than those adapted to be raised by counterweights.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to bo performed we declare that what
we claim is
1. The combination with a sliding sash constructed to be raised by means of
counter weights, of the weight or spring a, adapted to operate the break e, the said.
break being provided with means for releasing the same from either side of the
sash substantially as herein before described and represented in figures 1 to 7 of the
accompanying drawing.
2. The use in combination with a sliding sash of a tumbling weather board such
as 9, substantially as hereinbefore described.
.
3. The modified arrangement herein described for automatically raising the sash
of a railway or other carriage window by using the strap which is at present
usually upon the sash and the roller over which the strap passes substantially as
hereinbefore described and represented in figure 8. of the accompanying drawing.
4. The improved sashes for carriage doors and windows hereinbefore described
and represented in the various figures of the accompanying drawing.
