PROVISIONAL SPECIFICATION.
Improvements in Rag and Waste Tearing Machines.
1, THOMAS WALTER HARDING of the Tower Works, Leeds, in the County
of York, Engineer do hereby declare the nature of this invention to be as
follows:-
My invention consists in combining for the covering of rag and waste tearing
machine swifts, segments or lags of iron or steel, with teeth of flat section with or
without heads.
The metal segments are fitted with holes to suit the teeth. These may be made
either by first drilling one hole and then passing through it a drift or punch to
widen the hole to suit the flat pin; or, as is preferable, two holes may be drilled
and the space between them punched out so as to produce a flat hole of suitable
size to fit the pin.
The metal segments are screwed or bolted to the cylinder, and if desired, their
ends may be secured by iron hoops.

COMPLETE SPECIFICATION.
Improvements in Rag and Waste Tearing Machines.
1, THOMAS WALTER HARDING of the Tower Works, Globe Road, Leeds in
the County of York, Engineer do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
My invention consists in combining for the covering of rag and waste tearing
machine swifts, segments or lags of iron or steel, with teeth of flat section with or
without heads.
The metal segments are fitted with holes to suit the teeth. These may be made
by first drilling one hole and then passing through it a drift or punch to widen the
hole to suit the flat pins; or, as is preferable, two holes may be drilled and the
space between them punched out so as to produce a flat hole of suitable size to fit
the pin.
The metal segments are screwed or bolted to the cylinder, and if desired, their
ends may be secured by iron hoops.
In the accompanying drawing, Fig. 1 represents a longitudinal section of part of
a lag set with flat teeth as described. Fig. 2 represents a transverse section of the
same lag. Figs. 3, 4 and 5 represent plans of parts of the same lag.
In Fig. 4 I show
In all these figures the lag is marked A and the teeth B B.
the lag drilled with double holes CC and with single holes D D ready for drifting
out for the flat holes as shewn in Fig. 5 at EE and F F respectively. In
Figs. 1, 2 and 3 I show the lag with the teeth filled in.
The teeth I use are fully described in my Patent Specification No. 2252
1000

page_text: I sometimes prefer to use these teeth without their heads, or I may use the
flattened staples or double teeth described in the same specification.
The round holes may be drilled in the lags by an ordinary lag drilling machine
working by hand, or preferably by an automatic machine such as is described in
my Patent Specification No. 16819 A.D. 1890.
The round holes may be drifted into their flat shape either by a hand drift or
by fixing a drift to the non-rotating spindle of an ordinary lag drilling machine, or
preferably by the automatic punching machine described in my Patent Specification
No. 16819 A.D. 1890.
The drift used may be of any suitable description or a series of drifts of increasing
sizes may be employed.
The teeth may be filled and driven into the lag by any convenient method.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Iron or steel lags or segments for use in the coverings of rag and waste tearing
machine swifts set with flat teeth having their thinner edges presented to the
working direction of the swift substantially as described and shewn.
Dated this 17th day of June 1896.
T. WALTER HARDING.
