PROVISIONAL SPECIFICATION.
Improvements in Window Sashes and the like.
JOHN PARKER No. 111 Conybere Street Birmingham Builder do hereby
declare the nature of this invention to be as follows:-
My improvements consists in facing the middle or meeting rails with hard wood
in such a manner as to make it almost impossible to break or chip the edges or
angles, it also effectually prevents burglars and others opening the sash from outside,
without breaking the window, it also prevents all draughts, entering the room, and
becomes air, dust, and water tight when closed.
The way I propose to effect my improvements are as follows-In the face of
each middle or meeting rail, I make a groove either dovetailed parallel or other
suitable shape and depth, the whole length of rail, into which groove is fitted a
piece of mahogany, oak, pitch pine or other suitable wood half inch, or suitable
thickness, and half the width of rail, the hard wood being set at right angles with
each other, in the two rails, and running from end to end thus forms a rabbet, so
that when the two rails meet in position the hard wood forms a parallel face
between the deal rails.

Improvements in Window Sashes and the like.
JOHN PARKER Builder etc. Conybere Street Joinery Works Birmingham 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 improvements consists in facing the middle or meeting rails, with hard, or
soft wood, metal, india rubber composition or other suitable material, in such a
manner as to make it almost impossible to break or chip the edges or angles it also
effectually prevents burglars or others opening the sashes from outside without
breaking the window.
The ways, I propose to effect my improvements are as follows, in the face of
each middle or meeting rail I make a groove either dovetail, parallel, or other
suitable shape and depth, the whole length of rail into which groove is fitted a strip
of wood metal, india rubber, or other suitable material of the required thickness
and half the width of rail the wood, metal, or other material being set at
right angles with each other in the two rails and running from end to end thus
forms a rebate so that when the two rails meet in position the wood, metal, or
other material forms a parallel face between them-In one edge of each piece of
wood, metal or other material-1 make a groove into one of which is laid a string
of india rubber, or other elastic material or wood, so that when the sashes are
closed the india rubber or other material fits into each groove and thus the sashes
become absolutely, air, dust, wind, and water-tight. It also prevents any shaking
of the sashes from wind or other causes as when the sash fastener is closed it
effectually locks them together.
