CHARLES HARRISON, 61, Lancaster Street, Barnsley, Yorkshire, Joiner, do
hereby declare the nature of this invention to be as follows:-
The sash style is made in two separate pieces, viz.: sliding piece and style of
glazed sash the two styles are connected by a specially constructed ball pivot the
hollow box or carriage fixed on sliding piece and pivot or ball to be fixed on
glazed sash style thereby forming a perfectly air and weather tight joint at the
same time allowing the glazed part of sash to completely reverse on ball the
two styles are connected together at the bottom rail of bottom sash by a bolt
at each side and the top sash styles are connected by a bolt on each side to be
fixed on top rail.

CHARLES HARRISON, 61, Lancaster Street, Barnsley, Yorks, Joiner, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The sash styles are formed in two pieces; sliding piece A and glazed style B.
The sliding piece of top sash is half an inch thicker than sliding piece of bottom
sash, thereby allowing bottom sash and top sash to reverse and lap one on the
other. The sliding piece A is rabetted equal depth throughout and to overlap
The glazed
the glazed style B on the inside half of the bottom half of sash.
style B is rabetted so as to overlap sliding piece A on the inside half of top half
of sash. On the clapping edge of rabbet the pieces A & B are grooved and
tongued so that when the sashes are closed it draws the glazed style B and the
sliding piece A tight together so that they form a perfectly draught-tight joint.
The two styles are connected together by a ball pivot D attached to glazed style B
and a carriage E fixed on sliding piece A. The front plate F of carriage E is
hinged to back plate and secured by a thread-screw G. By removing thread-
screw G the glazed style B can be lifted completely out so as to attach new
cords &c. By using a specially constructed bolt L fixed to bottom of sliding
piece A (to work either way, M or N), when the window is open sliding piece A

page_text: is bolted fast to pulley style 0; and when sliding piece A is bolted to glazed
style B they both slide together.
Referring to the accompanying drawings:-
Fig. shows the elevation (looking towards the pulley style) of a portion of
the sliding piece (A); and of a portion of the glazed style (B) swung or reversed
upon the ball pivot (D).-N.B. For the purpose of more fully illustrating and
explaining the rabetting, the two pieces (A & B) are supposed to be cut
obliquely with the face of the wood, and the shaded ends show the elevations of
the oblique surfaces.
Fig. 2 is a front or inside view of portions of the sliding piece (A) and glazed
style (B); showing the ball-pivot and carriage connecting the said pieces (A & B)
together.
Fig. 3 is the plan of the section on H,I (Fig. 2).
Fig. 4 is the plan of the section on J, K (Fig. 2).
Fig. 5 is a front or inside view of a corner of the window frame showing the
working of the bolt (L).
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. An adapted tongue and groove to sash windows.
2. A specially constructed ball pivot & carriage for sashes & the like.
3. A specially constructed bolt as herein before referred to and illustrated in
the accompanying drawings.
