Year: 1879

page_text: LETTERS PATENT to Henry Leach Wilson and John Clegg, both of Clayton-le-
Moors, in the County of Lancaster, Washing Machine Makers, for the Inven-
tion of "IMPROVEMENTS IN SPRINGS FOR WASHING, WRINGING, AND MANGLING
MACHINES."
Sealed the 2nd March 1880, and dated the 8th October 1879.
PROVISIONAL SPECIFICATION left by the said Henry Leach Wilson and
John Clegg at the Office of the Commissioners of Patents on the 8th October
1879.
HENRY LEACH WILSON and JOHN CLEGG, both of Clayton le Moors, in the County
of Lancaster, Washing Machine Makers. "IMPROVEMENTS IN SPRINGS FOR
WASHING, WRINGING, AND MANGLING MACHINES."
This Invention relates to further improvements in springs for purposes aforesaid
of the class known as bow springs, for which application for Her Majesty's Letters
Patent was made on our behalf on the 11th day of September 1879, No. 3641, the
present improvements effecting a further considerable saving in metal and of labor
and time in the manufacture of such springs.
One construction of spring according to this our said Invention consists of a band
or strip (or strips) of steel, its edge being vertical save near its ends, where by a
twist given the strip its edges and ends are flat, that is to say, horizontal. The Hat
ends rest upon the necks or brasses of the rollers as usual.
Another construction is made from a bow of T steel, inverted 1; a portion of
the upper rib near the ends of the spring is cut away, so as to give greater elasticity
thereto.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Leach Wilson and John Clegg in the Great Seal Patent Office
on the 7th April 1880.

This Invention relates to further improvements in springs for purposes
of the class known as bow springs, for which application for Her Majesty's Letters

page_text: the present improvements effecting a further considerable saving in metal and of
labor and time in the manufacture of such springs.
One construction of spring according to this our said Invention consists of a band
(or strips) of steel, its edge being vertical save near its ends, where by a twist given
the strip its edges and ends are flat, that is to say, horizontal. The flat ends rest
upon the necks or brasses of the rollers as usual.
Another construction of spring is made from a bow of T steel, inverted 1; a
portion of the upper rib near the ends of the spring is cut away, so as to give greater
elasticity thereto.
Such being the nature and particulars of this our said Invention, we will now
proceed to describe the same in detail, and in order that the Invention may be fully
understood we have hereunto annexed a Sheet of Drawings illustrative thereof, and
have marked the same with figures and letters of reference.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2 are elevation and plan showing construction of spring from a single
strip or band of steel, its edge 1 being vertical except near its ends, where at 2 by
a twist given to the strip its edges and ends 3 are flat, that is to say, horizontal.
The flat ends 3, 3, rest upon the necks or brasses of the rollers as usual. Fig. 3
shows like construction, save that instead of the twist a portion of its end at 5, 5,
are cut away, so as to give greater elasticity. Figs. 4, 5, and 6 are elevation, plan,
and section of the spring made in form of a bow of T steel, inverted 1; a portion
of the upper rib 6 near the ends of the spring is cut away, so as to give greater
elasticity. Figs. 7, 8, 9, are elevation, section, and end view of the T section of
spring above referred to, the cross rib 7 being about midway the vertical portion of
the T, this section being somewhat easier to "roll;" the part 8 is the step or bearing
on which the ends of the spring rest when in working position; 9 is a wrought or
malleable iron cap on which the end of the ordinary pressure screw bears when
spring is in use.
Having thus fully described the nature and particulars of this our said Inven-
tion, together with the manner in which the same is to be performed or carried
into practical effect, we would have it understood that what we claim as our
Invention is,
Firstly. The construction and use of springs as described and illustrated by Figs.
1, 2, and 3 of the Drawings hereunto annexed.
Secondly. The construction and use of springs as described and illustrated by
Figs. 4, 5, and 6 of the annexed Drawings.
Lastly. The construction and use of springs as described and illustrated by Figs.
7, 8,0 of the annexed Drawings.
In witness whereof, we, the said Henry Leach Wilson and John Clegg, have
hereunto set our hands and seals, this Third day of April, in the year of our
Lord One thousand eight hundred and eighty.
