COMPLETE SPECIFICATION.
Improvements in the Furniture of Pivotted Window Sashes, part of
which is applicable to Sliding Sashes and to Doors.
We, JOHN PRICE JONES, of 27 Park Street, Cardiff, Architect, and ROBERT
WILLIAMS, of 15 Union Street, Cardiff, Foreman Builder, both in the County of
Glamorgan, 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 relates to improvements in the furniture of pivotted and sliding
window sashes, and relates, firstly, to the sash pivots and the method of fixing them;
secondly, to means for reversing the sashes, thirdly, to means for holding them at
any angle fourthly, to means for securing them when they are closed; and fifthly,
to making them or doors weather tight.
In order that the invention and the best means for carrying it into practical
effect may be thoroughly understood, we will now describe it and them in detail,
referring in so doing to the accompanying drawings which are to be taken as part
of this Specification and read therewith.
Fig. 1 is a front elevation of a two sash window.
Fig. 2 is a sectional elevation of a two sash window shewing both the sashes
open.
Fig. 3 is a detail side elevation, on a larger scale, of one of the pivots of the
bottom sash and of the locking plate.
Fig. 4 is a detail front elevation on the same scale of a pivot.
Fig. is a section on either line A-A of Fig. 1.
Fig. 6 is a section on either line B-B of Fig. 1.
Fig. 7 is a horizontal section on a larger scale illustrating the device for making
the sashes weather tight.
The pivots of the two sashes stand in planes one in front of the other in the same
way that one sliding sash stands in front of the other in the case of an ordinary
window.
b, c are a pair of plates. The former is fixed flush with the face of the hanging
style, and the latter with the face of the style of the sash.
d is a horizontal pin fast to either plate. It has its bearings in a socket on the
other plate. e is a washer on the pin between the two plates.
The two plates b, c, the pin d and the washer e constitute one pivot.
fis a plate which is fixed flush with the face of the hanging style, to one side of
the pivot and symmetrically above and below it. f', f' are holes all of the same
diameter, made in the plate each at the same distance from the pin d. g is a spring
bolt adapted to automatically engage in any one of the holes f. This combination
of plate and bolt may be applied to either or both sides of the window. It is
intended to be used for holding the sash open at any angle for ventilation or for
when it is being cleaned or painted on either side.
h, h are additional bolts for fastening the sashes after they have been shut.
The next part of my invention is the improved device for making a sash weather
tight.
Referring to Figs. 5, 6 and 7, i is a metal bar and jis a metal groove.
One of them
is fitted along the external side face of the frame of the sash and the other to or
along that member of the window opposite which the said one of them stands when
the window is closed, in such a way that the bars shall stand within the grooves j
and the grooves embrace the bars."
The groove and bar are fixed to the hanging style and
according to whether they are above or below the pivot.
style of sash, respectively,
The joint is let in clear of

The object
of this combination groove and bar is to serve as a weather guard and to make the
closed sash weather tight.

This weather guard is equally applicable to sliding sashes or to doors of any
"When the present invention is being applied to new work, it is preferable to make
a solid frame to receive the sashes, and at all times in hanging them, we prefer
that the pivotal line be set above the centre so that the lower portion of the sash
shall be the heavier.
Having now particularly declared and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is: -
.1. The hereinbefore described construction of furniture for a pivotted sash, as set.
forth and illustrated in the accompanying drawings.
2. The herein before described construction of furniture for pivotting window
sashes, holding them open at any angle and weather guarding them when they are
closed.
3. The hereinbefore described. weather guard for a closed sash or door, as set
forth..
