PROVISIONAL SPECIFICATION.
A New or Improved Hinge and Fittings for Sliding Windows.
THOMAS MARCUS HOUGHTON 137* St. Vincent Street Glasgow, N.B.
Surveyor do hereby declare the nature of this invention to be as follows:-
To the frame of the window I fix two strips of metal the full length of the
height of the window one for each sash. One of the edges of each of the strips is'
bent to a semicircular or circular shape or have a rod of metal attached to a strip
which is fixed projecting into a groove or sinking formed in the wood work of the
frame. To the sashes similar strips of metal with semicircular edges are fixed the
semicircular portion passing partly around or clipping and sliding on that of
the strips within the face of the frame and is prevented from leaving same by the
groove in the wood work which together forms a hinge. The sashes when free on?
the opposite side will swing round into the room in a similar manner to a case-
ment light to an angle of about 90 degrees that is to say square with the frame.
To allow of the bottom sash being opened to a greater angle than 90 degrees as
last described the semicircular part of the strip is fixed projecting into a rebate or
sinking formed in the edge of the frame but as in this form there is nothing to
prevent the sash from falling or from being blown inwards; the circular edge of the
strip which is fixed to the sash is continued and bent over the edge of the inner
strip to an angle or continued more than a semicircle or projections may be.
formed at intervals for that purpose.
Instead of a strip as described of the entire length of the sashes short pieces may
be substituted.
The strips of metal in combination with the groove or a rebate as described allow ..
of the sashes being hung on one side only forming a guide and in this manner
serve the purpose of stop and parting bead on that side of the window they also
form a weather tight joint that is to say when the strips are put the full length of
the sashes.
Both the groove and the rebate or sinking in the frame may be lined with
metal either on one or each of their sides for their entire length or at intervals.
As an alternative to the semicircular edge to the strips they may be bent square
or irregular in such a manner that the one clips and works on the other in the ..
groove or rebate.

A New or Improved Hinge and Fittings for Sliding Windows:
THOMAS MARCUS HOUGHTON 137A St. Vincent Street Glasgow N.B.
Surveyor 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 has reference to windows with sliding sashes and the object is as

page_text: follows viz. that the sashes may be opened inwards in a similar manner to casement
lights to enable the external face of the glass or wood to be cleaned or repaired
and painted from the inside of the room, to guide and retain the sashes in their
proper running position in the frame when they are hung with weights on one side
only and to form a weather tight joint in place of the parting and stop beads.
In order that my said invention and the manner of performing and carrying it
out in practice may be more readily effected I hereunto append explanatory
drawings in which the same reference letters apply to corresponding parts in each
of the figures where shown.
Fig. 1 is an elevation of the internal face of the window.
Fig. 2 is a horizontal section through the window below the meeting rails
shewing the top sash when pulled down (to clear the parting or cock bead on the
closing side) and opened into the room, and the bottom sash lifted up to clear the
stop bead on the cill and opened inwards in a similar manner.
Fig. 3 is a full size section on line J. L. Fig. 1 shewing the hinges and the
construction of the frame on the hanging side.
Fig. 4 is a full size section on line N. O. Fig. 1 and shows the construction of
the frame and the sashes on the closing side above the meeting rails for the top
sash and below same for the bottom sash.
In Figs. 3 and 4 the casings or boxings of the frame are not shewn but part
only of the pulley styles P.P. sufficient only to illustrate the method of application
of this invention.
Referring to these drawings I fix strips of metal A. B. the full length of the
in clear height of the window, one for each sash. One of the edges of each of the
strips is bent to a semicircular shape either more or less and are fixed projecting
into grooves or sinkings C. D. formed in the woodwork of the frame. To the
sashes similar strips of metal E. F. with semicircular edges are fixed the semi-
circular portion passing partly around or clipping and sliding on that of the strips
within the face of the frame and is prevented from disengageing from same by the
groove in the woodwork which together form a hinge.
The sashes when free on the opposite or closing side (and providing that there
is no projection or obstacle in their way on the hanging side) will swing round by
their hinges into the room in a similar manner to casement lights to an angle of
about 90 degrees that is to say square with the frame.
To allow of the bottom sash being opened to a greater angle than 90 degrees
(so that the top sash may be opened to an angle of 90 degrees or thereabouts) as
last described and as shewn in Fig. 2, the semicircular part of the strip E and A
are fixed projecting into a rebate or sinking D formed in the edge of the frame,
but as in this form there is nothing to prevent the sash from falling inwards or from
being blown or pushed inwards the semicircular edge of the strip E which is fixed
to the sash is continued and bent over the edge of the smaller or inside strip A to
an angle.
Instead of the strips E F as previously described being put of the entire length
of the sashes short pieces may be substituted.
The strips of metal A. B. E F. in combination with the groove C or a rebate D
as described allow of the sashes being hung on one side only forming a guide and
serve the purpose of stop and parting bead on that side of the window they also
form practically a weather tight joint that is to say when the strips are put the full
length of the sashes.
Both the groove C and the rebate or sinking D in the frame may be lined with
metal either on one or each of their sides for their entire length or at intervals.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1st. The improved hinge and fittings for sliding sashes consisting of two strips
of metal each with semicircular edge (or thereabouts) one sliding and turning on

page_text: the other in a groove formed in the woodwork for the top sash-substantially as
herein before described and shown in the accompanying drawings.
2nd. A similar description of hinge but and fittings with the larger of the two
strips continued and bent to an angle or curved over the curved edge of the smaller
strip one sliding and turning on the other in a rebate or sinking formed in the
woodwork for the bottom sash substantially as herein before described and shown
in the accompanying drawings.
Dated this Eighteenth day of October 1895.
