IMPROVEMENTS IN REVOLVING SHUTTERS
Year: 1872

page_text: LETTERS PATENT to Robert William Morris, of Ulverstone, in the
County Lancashire, for the Invention of "IMPROVEMENTS IN REVOLVING
SHUTTERS."
Scaled the 11th January 1873, and dated the 8th August 1872.
PROVISIONAL SPECIFICATION left by the said Robert William
Morris at the Office of the Commissioners of Patents, with his
Petition, on the 8th August 1872.
I, ROBERT WILLIAM MORRIS, of Ulverstone, in the County Lanca-
shire, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN REVOLVING SHUTTERS," to be as follows:-
The improvements consist in the lateral or backward and forward
motion of the roller of revolving shutters, and in regulating such back-
ward and forward motion by means of a stud or pin, or by other suitable
means, so that the shutter may always hang plumb whilst being rolled
or unrolled.

page_text: ALISO I MUking foners composite, maaying the centre or Core na
square, with fillets or pieces affixed on to form the round.
Also in the use of bands fixed with wooden pegs in lieu of the bands
fixed with iron screws in ordinary use, the objects of the improvements
being to keep the shutter always plumb in the groove, and avoid i
unnecessary friction as it is being rolled or unrolled.
Also to save time and material by the construction of the composite
roller, and further to save cost in the bands, and that they may be less
liable to get out of order.
The improvements may be readily performed by affixing to the rollers 1
at their ends a grooved wheel, made to revolve and travel backwards
and forwards in a journal constructed to allow of its necessary backwards
and forwards motion, and having a rail on which the grooved wheel can
run. The stud or pin for regulating the motion may be so made that
its circumference be equal to the thickness of the shutter, and be fixed 1
in the centre, and outside of the grooved wheel at each end of the roller,
and made to move in or on a recessed, grooved, or countersunk channel
cut in the journal plate, the length of the channel being proportioned to
the thickness of shutter and circumference of the pin. The grooved
wheels, studs, or pins and the journal can be made of metal. The chain 2
connected to roller and balance weights may be two-thirds the thickness
of shutter.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Robert William Morris in the Great Seal Patent
Office on the 30th January 1873.
