Improvements in Covering the Front Top Rollers of Spinning and
like Machines.
We, CHARLES HENRY BRIGGS, of Bowling Mills, in the City of Bradford,
Spinner, and SAMUEL. ROTHERA and JOIN LOXAM, of the same place, Mechanics,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to cover what are commonly called the front
top rollers of spinning and like machines, in such a manner that, less pressure
is required on the rollers to obtain the necessary draught than is the case when
the rollers are covered in the manner as hitherto, also to dispense with the cloth
or other like and independent cushion placed beneath the covering for producing
what is known as a "soft covered roller" and to so arrange the covering that
there is no square or what is termed a jumped joint" of the covering.
In carrying out this invention, we form the wood or iron top front rollers of
spinning, roving and like frames as hitherto, and cover each roller with a long
band of leather or other covering material of suitable width, each end of the
leather or like band being cut in a taper direction for some distance from
cach end.
.
One of the taper ends of the covering is attached to the wood or iron roller
which is then rotated, the covering being kept in tension in any convenient
manner so that it is wrapped around the roller as it rotates. The covering is
of such length that it extends several times around the circumference of the
roller, and as it is being wrapped around same, one side of the covering is coated
with cement which by the tension on the covering causes it to adhere to the
surface below, and by the end of the covering being cut taper, the thickness
gradually diminishes, leaving no abrupt termination, which is temporally secured
by nailing.
When the cement is thoroughly dry, the covering is turned to the diameter
required, the rollers are then ready for use, and by wrapping the covering around
the roller so that there are several thicknesses, the covering is more elastic, re-
quiring less pressure to obtain the necessary amount of draught; and by dis-
pensing with the ordinary "jumped joint" the liability of producing defective
yarn by one portion of the covering rising above the other is obviated.

like Machines.
We, CHARLES HENRY BRIGGS, of Bowling Mills, in the City of Bradford,
Spinner, and SAMUEL ROTHERA and JOHN LOXAM, of the same place, Mechanics,
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:
The object of this invention is to cover what are commonly called the front
top rollers of spinning and like machines, in such a manner that, when the
rollers are in operation, less pressure is required on the rollers to obtain the
necessary draught than is the case with rollers covered in the manner as
hitherto also by our improvement, to dispense with the cloth or other like and
independent cushion placed beneath the leather or outward covering, for pro-
ducing what is known as a "soft covered roller"; and to so arrange the improved
covering that, there is no square or what is termed a 'jumped joint" in the
covering.
"
In carrying out our invention, we form the wood or iron top front rollers of
spinning, roving and like machines as hitherto, and cover each roller with a
long band of leather, or other covering material of suitable width, each end of
the leather or like band being cut in a taper direction for some distance from
each end.
In describing our invention in detail reference is made to the accompanying
sheet of drawings in which Fig. 1 represents a side elevation of a front top roller
covered in accordance with this invention, and Fig. 2 is a sectional elevation of
the same.
On covering a pair of rollers A. arranged on a spindle B in the ordinary
manner, the same may be placed between a lathe or like centres, and one of the
taper ends C of the covering C¹ attached to the wood or iron roller A in any
convenient manner, such as by wooden pegs driven through the end of the cover-
ing into the wooden roller, or into wood inserted tight into holes formed in the
iron rollers.
The pair of rollers are then rotated between the lathe or like centres, the
covering C¹ being kept in tension and guided on to one of the rotating rollers A
in any convenient manner, so that the leather or like covering is tightly and
spirally wrapped around the roller A as it rotates.
The covering C¹ is by preference made rough on the two flat surfaces and is
of such length that, it extends several times around the circumference of the
roller A, and as it is being tightly and spirally wrapped around same, one side
of the covering is coated with liquified cement, which by the tension of the
covering, causes it to adhere to the surface below, and by the finishing end C³ of
the covering being tapered, that is the thickness gradually diminishing for some
distance to the end, leaves no abrupt termination, the tapered end being secured
by nailing until the liquified cement is hard and dry.
When both rollers on the spindle are covered and the cement is thoroughly
dry, the nails are withdrawn and the coverings turned in a lathe to the diameter
required, when the rollers are ready for use.
By spirally wrapping the covering around rollers so that there are several
thicknesses, the covering is more elastic, giving more cushion or grip on the
bottom roller, thus requiring less pressure to obtain the necessary amount of
draught and uniform delivery of fibre; and by dispensing with the ordinary

page_text: "jumped joint" on the covering, the liability of one end of the covering rising
above the other and thereby producing defective yarn is obviated.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
The method of covering rollers used on spinning and like machines with a
strip of leather or the like wrapped spirally around and secured to the rollers,
substantially in the manner as herein before described.
