IMPROVEMENTS IN NOZINGS FOR STAIR TREADS
Year: 1880

page_text: LETTERS PATENT to Froderick William Hembry, of 16, Newgate Street, in
the City of London, for an Invention of "IMPROVEMENTS IN NOZINGS FOR
STAIR TREADS."
PROVISIONAL SPECIFICATION left by the said Frederick William Hembry
at the Office of the Commissioners of Patents on the 18th September 1880.
FREDERICK WILLIAM HEMBRY, of 16, Newgate Street, in the City of London.
"IMPROVEMENTS IN NOZINGS FOR STAIR TREADS."
This Invention has for its object improvements in nozings for stair treads.
In order to prevent the rapid wear of stair treads it is common to apply to them
nozings, which usually are of brass, cast to the curved form required to fit over
the noze of the stair tread."
According to my Invention I produce nozings which are altogether free from
the objection to which metal nozings are open, viz., that they are slippery and
dangerous, and which besides are very durable and comparatively inexpensive.
I form the nozings of vulcanized india rubber held in.a frame of sheet metal.
The sheet metal is bent to the form of the nozing and is adapted to receive and
form a backing for the vulcanized india rubber.
A strip of stout vulcanized india rubber sheet of the width and length of the
nozing is fixed in this frame, and is nipped at its edges by the sheet metal which
is turned over upon it. The attachment is also rendered more secure by cement
applied at the back, and the india rubber can be vulcanized on to the plate or
frame.
The nozing is attached to the stair tread by screws passing through the india
rubber and through the sheet metal frame, and the heads of the screws bed.
themselves in the india rubber.
