Frederick Sayer at the Office of the Commissioners of Patents, with
their Petition, on the 15th August 1866.
We, HENRY JAMES PETTY, of No. 1, Prospect Terrace, Stoke Newington,
Middlesex, Machine Ruler, and CHARLES FREDERICK SAYER, of No. 49, Queen's
Road, Dalston, Middlesex, House Decorator, do hereby declare the nature of
the said Invention for "AN IMPROVED AND SIMPLE, METHOD FOR THE WORKING OF
PERPENDICULAR SLIDING SASHES, DOORS, AND SHUTTERS, OR ANY OTHER PERPEN-
DICULAR SLIDING FITTINGS, BY THE AID OF SPRING ROLLERS; AND THE CONSTRUCTION
OF THE SELF-SECURING MOVEABLE BEADS TO ADMIT OF SUCH SLIDING SASHES, DOORS,
AND SHUTTERS, OR OTHER PERPENDICULAR SLIDING FITTINGS BEING TAKEN OUT FOR
THE PURPOSE OF CLEANING OR OTHERWISE," to be as follows:

A steel spring, similar in design to a-carriage spring, with the addition of a
roller at each end, and of power adapted to the weight of the sash, door, shutter,
or other perpendicular sliding fittings to which it is intended to be fixed or '
fastened. The rollers to be composed of metal or other hard material, which
may be covered with leather, india-rubber, or other soft substance to deaden the
sound if found necessary. The spring may be made either with double or
single rollers; the double roller spring is the spring above described with a roller
at each end. When the double roller spring is used one spring is fixed with
common screws in the centre of each side of the sash, door, shutter, or other
perpendicular sliding fitting, a groove having been first made for each roller
to work in. The rollers will run on the pulley stiles, and the sash, door,

page_text: shutter, or other perpendicular sliding fitting can by this means be raised or
lowered to the height desired. The single roller spring may be compared to a
double roller spring cut into two halves. When the
When the single roller spring is
used one roller spring is fixed with common screws as near to each of the two
corners of each side of the sasb, door, shutter, or other perpendicular sliding
fitting as practicable; this will be found an advantage when the sash, door,
shutter, or other perpendicular sliding fitting is at all out of the square,
inasmuch as the springs will. aid in maintaining the balance of the sash,
door, shutter, or other perpendicular sliding fitting. As the spring rollers
will in no way be fixed to the frame of the sash, door, shutter, or other
perpendicular sliding fitting such sash, door, shutter, or other perpendicular
sliding fitting can be easily lifted out of the frame by the introduction of self-
securing moveable beads which may be applied to one or both sides of the
frame, and will be constructed as follows:-What has hitherto been considered
as one bead we propose to divide into two parts, to be called the upper bead
and the lower bead, the upper bead being one-third of the length of the frame,
and to be a fixture. At the lower end of the upper bead is an incision or
socket intended to receive a tongue or tenon formed at the upper end of the
lower bead. The lower bead is then dropped into a mortice cut in the sill of
the frame, whilst the upper end of such lower bead is slipped with ease into
the socket above described, thus at once forming a temporary fixture of the
The
lower bead. The parting beads are made of iron or other metal.
inner or front beads are constructed upon exactly the same principle, and
from their greater substance can be composed of wood if preferred, having
metal ends for connecting their divisional parts as above described, whilst the
fixing or removing will be the same.
