Year: 1860

the Commissioners of Patents, with his Petition, on the 12th December
1860.
I, HENRY NEWEY; of Birmingham, in the County of Warwick, Umbrella
and Parasol Manufacturer, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF CERTAIN PARTS OF UMBRELLAS AND.
PARASOLS," to be as follows:-
These improvements relate, first, to the application of solid wire stretchers
in combination with solid steel ribs of umbrellas and parasols, such solid
stretchers being formed alike and pierced at both ends, or without the usual
forked end, as heretofore; and in order to connect solid stretchers of this
description to the solid ribs of umbrellas I employ middle bits or joints of
improved construction, which I prefer to form from a piece of sheet metal.
of the form of a cross (although other forms may be employed). This piece
of metal is bent up so as to embrace the back of the rib, and is closed.
thereon by suitable tools to attach it firmly thereto, as is well understood..
The two ends of the bit, which project inwards, form the horns or sides of the
joint, which are pierced with holes, and these raised sides receive the pierced
end of the solid stretcher between them, and are then connected by a pin to
form the joint. In some cases I form the middle bits with stops to prevent
the frame turning outwards.
The second part of my improvements consists in stamping or pressing the

page_text: notches of runners for umbrellas and parasols out of sheet iron whilst at a red
heat, by which mode of manufacture the iron notches so made are softer and
tougher than when stamped or punched from sheet iron in a cold state.
The third part of my improvements consists of an improved mode of
attaching the solid knobs or ends to the ferrule ends of metal tubes used in
the manufacture of umbrellas and parasols. For this purpose, in place of
securing the solid knob or end to the tube by a pin passed through the sides
of the tube and the solid stem of the knob, I make the stem of the knob of a
slightly taper-shape, its smallest circumference being just below the knob or
enlargement at the end, the other end of the stem corresponding with the size
of the inner circumference of the tube, so that when it is inserted in the tube
the end of the tube is closed or contracted by suitable tools and pressure
around the smaller circumference of the stem, by which the solid knob or end
will be securely retained within the tube.
The fourth and last part of my improvements consists in the method of
straightening the metal tubes-employed-in-the-manufacture of umbrellas and
parasols. For this purpose I pass the metal tubing to be straightened through
a machine similar to that described for straightening wire in the Specification
of a Patent granted to James Cocker, and dated the 10th day of December,
1855, No. 2781, and I cause the tubing to pass slowly through the machine
and be strained over suitable antifriction rollers (each capable of adjustment)
mounted in a rotating frame, by which injurious friction is avoided.
