PROVISIONAL SPECIFICATION.
Improvements in Casement and other like Stays.
I, PHINEHAS EDWARD AYTON of the firm of Thomas Pemberton and Sons of
Livery Street in the City of Birmingham, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in casement and other like stays, for
holding and securing in position French casements, and windows generally, and the
object of my said invention, is to obtain a quicker and more certain grip than has
heretofore been attained.
My invention consists primarily, in the top side of the bar, which I make longi-
tudinally fluted or channeled up its middle, leaving the opposite sides to form the
bearing for the pressure plate.
Heretofore the said top sides of the bars of the casement stays, have been
made flat or plain, and on the clamping screw being screwed home, the pressure
plate is some time before it finds its bearing, sufficient to form a grip.
By having a longitudinal cavity sunken along the middle of the top side of the
bar, as according to my invention, an instantaneous grip is attained.
In carrying out my invention, I preferably construct a stay as follows:-
The box consists of an open ended rectangular shaped short sleeve, with an inside
screwed neck, directed perpendicularly from its top side, and a swivelling attach-
ment plate, on its underside, and down the screwed middle of the neck upon the
upper side, a clamping screw pin, with a thumb lever or turn (at its upper end)
takes, and presses upon the top side of a pressure plate, disposed between the
top of the inside of the box, and the top side of the bar of the stay.
The inner end of the bar, is jointed to and comes between, the knuckles of an
attachment bracket, while the other end has a stop.
The bar is as aforesaid, longitudinally channeled or fluted up its middle, leaving
arched sides, upon which, the underside of the pressure plate, comes, and forms
thereby an instantaneous grip.
The underside of the bar is preferably of an inverted trough section, so that
the opposite edges only, rest and take their bearings upon the bottom of the box.
Thus, the said bar is longitudinally sunken about its middle, both upon its top
and under sides.
I wish it to be understood, that I do not confine myself to the particular con-
struction of stay, so long as the bar is longitudinally sunken upon the middle of its
top side, although I prefer that the said bar should be longitudinally sunken upon
its bottom side as well; and further, nor do I confine myself to the section of the
sunken part, so long as the sides are left.
In case the clamping screw is repelling in its gripping action, instead of
propelling, with the pressure plate coming upon the underside of the bar, then
make the underside of the configuration of the top as aforesaid.
The said bars are made preferably from a drawing or rolling process, and of
sheet metal, but to this I do not limit myself, as the same may be made by casting.
Or instead of a single longitudinal channel or cavity, two or more may be formed;
and further, by such channellings, flutings, or corrugations, the bar's transverse
strength is greatly increased.

Improvements in Casement and other like Stays.
I, PHINEHAS EDWARD AYTON, of the firm of Thomas Pemberton and Son of
Livery Street in the City of Birmingham Manufacturer 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 improvements in casement and other like stays, for
holding and securing in position, French casements, and windows generally of the
folding type, and the object of my said invention, is to obtain a quicker, and more
certain grip, than has heretofore been attained, on the screwing down of the
clamping device.
The said invention consists primarily, in longitudinally ribbing, fluting, or
channelling the bar, or the stay rod, or pressure plate of the said casement or other
like stays, as hereinafter described.
Heretofore, the said bars, and pressure plates, have been made flat or plain, and
on the clamping screw, being screwed home, the pressure plate is sometime before
it finds its true bearing, sufficient to form a proper grip.
By having a longitudinal cavity sunken along the middle of the top side of the
bar, or about the middle of the pressure plate as according to my invention, an
instantaneous grip is obtained.
In carrying out one form of my invention, I preferably construct a stay, as
follows:-
The box, consists of an open ended rectangular shaped short sleeve, with an
inside screwed neck, directed perpendicularly, from its top side, and a swivelling
attachment plate, on its underside; and down the screwed middle of the neck, upon
the upper side, a clamping screw pin, with a thumb lever or turn, (at its upper
end) takes, and presses upon the top side of a pressure plate, disposed between the
top of the inside of the box, and the top side of the bar of the stay. The inner
end of the bar, is jointed to, and comes between, the knuckles of an attachment
bracket, while the other end has a stop.
The bar is as aforesaid, longitudinally channelled or fluted up its middle, leaving
arched sides, upon which the underside of the pressure plate comes, and forms
thereby an instantaneous grip.
The underside of the bar is preferably of an inverted trough section, so that the
opposite edges only, rest and take their bearings upon the bottom of the box.
Thus, the said bar is longitudinally sunken about its middle, both upon its top
and undersides.
I wish it to be understood, that I do not confine myself to the particular con-
struction of stay, so long as the bar is longitudinally sunken upon the middle of its
top side, although I prefer that the said bar should be longitudinally sunken upon
its bottom side as well; and further, nor do I confine myself to the section of the
sunken part, so long as sides are left.
-
In case the clamping screw is retracting in its gripping action, instead of
propelling, with the pressure plate coming upon the underside of the bar, then
make the underside, of the configuration of the top side as aforesaid.
The said bars are made preferably from a drawing or rolling process, and
of sheet metal, but to this I do not limit myself, as the same may be made by
casting.
Instead of a single longitudinal channel or cavity, two or more may be formed,
and further by such channellings, flutings or corrugations, the bars transverse
strength is greatly increased.
In a casement stay provided with a ribbed or channelled pressure plate 1 form
the bar perfectly plain, and acquire the necessary, and sure grip, by the ribs of
the said plate, taking their bearings on its top side.

page_text: Figure 1 of the accompanying drawings, represents partly in vertical section, and
partly in elevation, an instantaneous grip casement stay, constructed and arranged
according to one form of my invention. The bar of the said stay, is longitudinally
channelled or fluted up its middle, leaving bearings for the pressure plate to come
upon the two opposite sides or ribs, hence an instantaneous grip.
Figure represents a transverse vertical section of the same, showing the shape
of the cross section of the bar, and how the underside of the pressure-plate, takes
its bearing upon the opposite arched sides or ribs of the top; and also, how
the underside of the said bar, takes its bearing upon the bottom of the box.
Figure 3 is a topside plan of Figure 1.
Figure 4 is a topside plan of a length of drawn, or rolled metal, from which
the bar is made.
Figure 5 is an edge view of the same, and
Figure 6, a transverse section.
The same letters of reference, indicate corresponding parts, in Figures 1 to 6.
a is the bar, with a longitudinal channel, or fluting a², up its middle, and with
opposite bearings or ribs a³, upon its top side, and upon which, the pressure
plate b, fitted within the hollow c³, of the box c, takes its bearing.
The sides of the said bar, which are marked a', are like unto longitudinal feet
or webs, which take their bearings upon the bottom of the hollow, of the said
box, so that as the clamping screw d, with its thumb turn d³, is screwed home,
through the perpendicular neck c³, of the box c, the pressure plate b, instantly finds
its true bearing, hence an instantaneous grip.
The underside of the bar, or the sides thereof, also assist in finding a true
bearing of the bar, upon the bottom of the hollow of the box.
e is an attachment plate, swivelly connected to, an underside neck c', of the
box c, and which attachment plate, is connected to a framing f, whilst the inner
end of the bar, is jointedly connected to an attachment bracket y, by a pin a³, and
which bracket g, is connected by small screws as usual, to a sash or window-frame h.
The other end of the bar has a stop aⓇ.
The bar, although preferably made from drawn, or rolled metal, may be made,
if necessary, by casting.
Figure 7 represents a casement stay, with an inverted bar, as in the preceeding
figures, showing that a light gripping action is attained, whether the channelled part
of the bar, be presented to the bottom of the box, or the underside of the feet, or
sides, be presented to the pressure plate.
Figure 8 represents a box of the casement stay, with a bar having double
longitudinal flutes or channells, instead of a single one, as in the preceeding
figures.
a is the stay with double flutings a², opposite bearings or ribs a³, webbed sides a*,
and a middle rib a', and which latter is at a lower plane, than the tops of the
bearings a³, aforesaid.
Besides enhancing the gripping power of the said stay, the said flutings increase
also the transverse strength of the bar.
Figure 9 represents in transverse section, a casement stay, constructed according
to another form of my invention, and Figures 10, 11, and 12 are separate views of
the pressure plate of the same.
In this arrangement the pressure plate is troughed, ribbed or fluted, in
manner, to leave longitudinal bearing parts alike unto those of the bar, as
described.
When the said pressure plates are provided with longitudinal bearings, the
bar, or the stay rod is plain.
a is a plain bar, b is a corrugated, ribbed or fluted pressure plate, with bearing
parts 6, upon its two opposite sides, and with an arched middle part 6³, upon which
the end d, of the thumb screw d³, impinges. c is a box, with hollow or eye ²,
neck c, which is internally wormed, and down which the screw d³, takes.
The screwing home of the said screw, causes the pressure-plate, to immediately

page_text: find its bearing upon the top side of the bar, hence an instantaneous grip. The
box is fitted with a swivelling attachment plate e.
Figure 13 represents another form of my invention.
In this arrangement the bottom of the eye or hole within the box, has
bearings upon which the opposite sides of the underside of the bar, comes, whilst
the top side of the bar, is pressed upon, by a ribbed pressure plate, alike unto
Figure 9.
a is a plain bar, is a ribbed pressure plate, c is a stay bar box, with body part c¹
having an eye or all-through. opening c², with the bottom of the same, having
shelf-like rests c, upon which the opposite underside edges of the bar, come.

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:
First In casement, and like stays, making the bars, or the stay rods of them,
longitudinally fluted, corrugated, ribbed, or sunken about their middles, and upon
their top sides, or upon their bottom sides, or upon both their top and bottom sides,
substantially as, and for the purpose, as described and set forth.
Secondly-In casement, and like stays, making the bars, or the stay rods of.
them, longitudinally fluted about their middles, and with opposite side ribs, or side
bearings, both at top, and on underside, substantially as described and set forth in
Figures 1, 2, 3, 7, and 8.
Thirdly Making longitudinally fluted, or ribbed stay bars, or stay rods of the
kind as described, from sheet metal, by drawing or rolling, as set forth in
Figures 4, 5, and 6.
:―
Fourthly Forming the pressure plates, of casement or like stays, with ribs,
flutings, or corrugations, substantially as, and for the purpose as described, and set
forth in Figures 9, 10, 11, 12, and 13.
Fifthly In casement stays, as described and set forth.
