Year: 1884

page_text: I THOMAS TOBITT of 24 De Laune Street, Kennington in the county of Surrey
Builder do hereby declaro the nature of my said Invention for IMPROVEMENTS. IN
SLIDING WINDOW SASHES to be as follows:-
The object of my invention is to fit sliding window sashes in such a manner that
they can easily and quickly be turned to allow of cleaning or otherwise treating
the outer sides thereof and in order thereto I arrange that these sashes shall bo
.enabled to slide fairly and truly without any parting or other beads.
To carry out this invention I. form the window sashes in the usual or other
convenient manner and in the lower part of the side stiles of each sash or in the
bottom rails thereof I form a recess on each side in the which I fit a sliding bolt
the handle of which projects on the inner face of the sash frame. A suitable
groove is ploughed out of the pulley stile of the window frame and the bolt is so
arranged in the sash that the case or socket thereof projects from the said sash and
enters this groove and can travel upwards and downwards therein as the sash is raised
or lowered. In a suitable position in this groove preferably near the bottom of the
frame I form a recess which may be protected by a perforated plate in which the
end of the sliding bolt can engage when the said bolt is pushed out. The cords by
which the sashes are hung or suspended are secured round the projecting ends of
the sockets or cases of the bolts or to strips of metal fitted round the same or
otherwise and the said cords pass up the grooves in the pulley stiles and over the
usual pulleys in the upper part of the frame and are attached to the usual counter-
weights. A small groove is also ploughed out of the side stile on each side of the
sash preferably at or about the centre longitudinally thereof and a corresponding
groove is also mado in the pulley stile. A strip of metal or other material is inserted
in these grooves and in this manner the sash can slide freely and fairly and truly
in the proper position without any beads.
When it is desired to turn the sash for the purpose of treating the outer side
thereof the sash is preferably pulled down to the bottom of the frame the bolts are
shot into the recesses formed therefor in the grooves and the strips of metal are
drawn out and removed. The upper part of the sash can then be drawn inwards
the sash turning on the bolts as on pivots. When necessary to enable ine to turn
the upper sash in this manner free and clear of the lower sash a recess is made in.
the window head sufficient to enable the lower sash to enter therein and clear the
top rail of the upper sash which can then be turned and if brackets are fitted to the
lower part of the upper sash small portions thereof can be removed to allow them
to pass the outer lining if any when the sash is turned.
Similar recesses can also be made in other positions in the grooves so that when
the bolts are shot thereinto the sashes can be secured in any desired position.

I THOMAS TOBITT of 24 De Laune Street, Kennington in the county of Surrey
Builder do hereby declare the nature of my said invention for IMPROVEMENTS IN
SLIDING WINDOW SASHES and in what manner the same is to be performed, to be
particularly described and ascertained in and-by the following statement :-
The object of my invention is to construct and fit sliding window sashes in such
a manner that they can easily and quickly be turned to allow of cleaning or
otherwise treating the outer sides thereof and in order thereto I arrange that these
sashes shall be enabled to slide freely fairly and truly without any parting or other
beads.
In order to clearly explain my invention and in what manner the same is to be :
performed I refer to the accompanying drawing.
Figure 1 is a vertical longitudinal section partly in elevation of so much of a
window sash and of the frame thereof as is required to exhibit this my invention.
Figure 2 is an horizontal transverse section of the same taken at the several
required levels.
The window sashes are formed in the usual or other convenient manner and in
the lower part of the side stile A of each sash or in the bottom rail B thereof on
each side is fitted a bolt C which may be a sliding bolt in which case the handle D
thereof projects on the inner face of the sash frame. A groove E is ploughed
vertically out of the pulley stile F of the window frame and according to this form
thereof the bolt C is so arranged in the sash that the case or socket G thereof
projects out from the said sash and enters the said groove E and can travel upwards
and downwards therein as the said sash is raised or lowered. In a suitable position
in the back of the groove E preferably near the bottom of the window frame I form
a recess H which may be protected by a suitable plate I in which recess H the end
of the sliding bolt C can engage when the said bolt C is pushed out. The cord K
by which the sash is hung or suspended in the usual manner is secured on each side
of the said sash it may be round the projecting end of the case or socket G of the
bolt or as is preferably arranged to strips of metal or material L.fitted round the
same or otherwise and the said cord K passes up the groove E in the pulley stile F
to the usual pulley in the upper part of the frame and is attached to the usual
counterweight or the said cord K can be otherwise fitted as may be suitable
convenient or desirable in each case. A small groove M is also ploughed vertically
out of the side stile A on each side of the sash preferably at or about the centre
thereof longitudinally and a corresponding groove N is also made in the pulley
atile F which groove N may if desired be incorporated with the aforesaid groove E
as shewn in the drawing. A strip of metal or other material O is inserted in these
two corresponding grooves M and N fitting rather loosely therein and by this
arrangement the sash can slide freely fairly and truly in the proper position without
any beads being guided by the said strip O. To this strip O especially and
necessarily when the groove N is incorporated as aforesaid with the groove E
I preferably attach a longitudinally angled web P which surrounds the cord K and-
by coming in contact with the case or socket G of the bolt when the sash is raised
causes the strip O to rise therewith,

page_text: I can also make the bolt C a fixture and not a sliding bolt if and when I should
so prefer as shewn at C and in this case the aforesaid recess H is made in the sido
of the groove E in the pulley stile F as shewn at H instead of in the back thereof
as hereinbefore described which recess H¹ may also be protected by a suitable
plate I and the said bolt C¹ has an elbowed, or eccentric head R which when the
sash is in the vertical position and ready for sliding in the frame depends down.
wards and the cord is secured as before described round or to the neck of the bolt
inside the head.
The action of this apparatus and arrangement as herein before described is as
follows. The sashes when in the vertical positions shewn in the drawings can
obviously slide freely fairly and truly upwards and downwards as may be required
being kept in position by the guiding strips and supported by the cords attached
to the bolts but when it is desired to turn the sash for the purpose of treating the
outer side thereof the said sash is placed in such a position in the frame that tho
said bolts are opposite to or on a level with the recesses formed in the grooves in
the pulley stiles and when so formed the sliding bolts are then shot into the said
recesses. The guiding strips are then drawn out of their grooves and removed
when the upper part of the sash can be drawn or pulled inwards the said sash
turning on the bolts as on pivots while there is no danger of the lower part of the
said sash being overbalanced or overweighted by the counterweights and therefore
sliding upwards in the frame as in the one case or according to the one form thereof
the sliding bolts are shot into and engage the recesses formed in the backs of the
grooves and in the other case or according to the other form thereof the heads of
the fixed bolts are turned into and engage the recesses formed in the sides of the
said grooves as the said sash is turned.
It is obviously most convenient to make the recesses in which the pivot bolts are
engaged when the sashes are to be turned as aforesaid at or near the bottom of the
window frame for both or all the sashes and when necessary to allow the upper
Bash to be turned in this manner free and clear of the lower sash a recess may be
made in the window head sufficient to enable and allow the said lower sash to enter
therein and clear the top rail of the said upper sash when the same is drawn down
and the said upper sash can then be turned as is desired and if brackets are fitted
to the lower part of the said upper sash as is common small portions thereof can be
removed to allow the same to pass the outer lining if any of the window frame
when the sash is turned.
When the aforesaid pivot bolts are sliding bolts similar recesses can also be made
in other positions and at other levels in the grooves so that when the said bolts are
shot thereinto the sashes can be secured in any desired positions.
I would also have it clearly understood that though I consider that the shapes
and methods of construction of the bolts and of the other parts of this my apparatus
as shewn in the drawing are very suitable and convenient yet I do in no wise limit
myself thereto for the said bolts and other parts may be formed of such shapes and
such details may be observed and followed in the construction of the same as may
be desirable or convenient in each particular case.
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
1. The windows constructed and fitted substantially as herein before described
and set forth and shewn in the accompanying drawing.
2. In the pulley stiles of sliding window sashes the grooves E with the
recesses H therein substantially as and for the purpose hereinbefore described and
declared.
3. In sliding window sashes the combination of the strips O fitting in the
grooves M and N and the bolts C with or without the cases or sockets G to which
bolts C the cords K are attached substantially as hereinbefore described and set
forth,

page_text: 4. In sliding windows the combination of the strips O the grooves M and N the
bolts C with or without the cases or sockets G the grooves E and the recosses H
the whole combined and operating substantially as and for the purposes hereinbefore
described and declared.
