PROVISIONAL SPECIFICATION.
Improvements in Machines Employed in the Manufacture of Knitted
Pile Fabrics.
I. JAMES BOOTH of Lee Mills, Halifax in the County of York, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to machines heretofore employed in the manufacture of
knitted, looped fabrics, and consists in the application to and combining therewith
certain appliances for receiving and holding the loops in position whilst being cut and
severed, producing pile fabrics such as plush, seals, and the like on machines hereto-
fore available only for the production of knitted looped fabrics.
This invention relates to the class of knitting machines known as straight bar
machines, and in combination with the needles and sinkers and guides, I employ on a
longitudinal bar opposite the sinkers a series of cranked hooks or stems composed of
either duplicate parts, the points of which are connected whilst the opposite ends of
the shanks are spaced and secured in a bar of lead or spelter, or of two such cranked
hooks or stems spaced a distance apart. Within the space between the duplicate
parts of each cranked hook or of each two said hooks is a portion of a circular
cutter or knife mounted on a longitudinal shaft and free to move laterally thereon
whilst being caused to rotate by a key slot formed on the cutter and a key on
the driving shaft.
As the pile loops are formed they are by the guide passed over the point of one of
the cranked hooks, or each loop is passed over two of the separate spaced hooks
when the latter are employed and which are so shaped and arranged in relation to the
protruding part or are of the circular cutter, that not until a series, or several loops
are deposited on the said cranked hook or hooks, will the first loop of the series, be
cut and severed, the accumulation of several loops beyond the range of action of the
circular knife, being designed to ensure the effectual tying in, and securing the pile
loops before severance, and as the leading loops of the series are being severed by the
circular cutter a proportionate number of new loops are being added or placed upon
the cranked hook or hooks.

Improvements in Machines Employed in the Manufacture of Knitted
Pile Fabrics.
I, JAMES BOOTH, of Lee Mills Halifax in the County of York Manufacturer, 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:
This invention relates to machines heretofore employed in the manufacture of
knitted, looped fabrics, and consists in the application to and combining therewith
O certain appliances for receiving and holding the loops in position whilst being cut and
severed, producing pile fabrics such as plush seals and the like on machines hereto-

This invention relates to the class of knitting machines known as straight bar
machines, and in combination with the needles and sinkers and guides, I employ
on a longitudinal bar opposite the sinkers a series of cranked hooks or stems
composed of either duplicate parts the points of which are free i.e. not connected to
Din

each other, whilst the opposite ends of the shanks are spaced and secured in a bar of
lead or spelter, or of two such cranked hooks or stems spaced a distance apart.
Within the space between the duplicate parts of each cranked hook or of each
two said hooks is a portion of a circular cutter or knife mounted on a londitudinal
shaft and free to move laterally thereon whilst being caused to rotate by a key slot
formed on the cutter and a key on the driving shaft.
As the pile loops are formed they are by the guide passed over the point of one of
the cranked hooks, or each loop is passed over two of the separate spaced hooks
when the latter are employed and which are so shaped and arranged in relation to the
protruding part or arc of the circular cutter, that not until a series, or several
loops are deposited on the said cranked hook or books, will the first loop of the
series, be cut and sovered; the accumulation of several loops beyond the range of
action of the circular knife, being designed to ensure the effectual tying in, and
securing the pile loops before severance, and as the leading loops of the series are
being severed by the circular cutter a proportionate number of new loops are being
added or placed upon the cranked hook or hooks.
Such being the nature and object of my invention the following is a complete
discription of same reference being had to the accompanying drawings in which :-
Fig. 1 is a front elevation of a part of a straight bar knitting machine, having my
improved icop cutting apparatus applied thereto."
Fig. 2 is a similar view to Fig. 1 but drawn partly in section.
Fig. 3 is a sectional end elevation of same.
Fig. 4 shews the appliances for giving the to and fro lateral motion to the
needles.
Fig. 5 is a plan view of one pair of cranked books and one cutter.
Fig. 6 is a plan view of two pair or sets of the hooks or stems and their circular
cutters, drawn about three times full size in order to show clearly how the loops
are cut.

The
According to this my said invention in that class of knitting machines known as
the "straight bar machine" I employ in combination with the guides 1. 1 needles 2
and sinkers 3 a longitudinal bar, or carrying frame 4 opposite to the sinkers 3, this
longitudinal bar or frame 4 carries a series of cranked hooks, or stems 5, the points 6
of the stems or books 5 are free, whilst the opposite ends or shanks are spaced
and secured in blocks or bars of lead or spelter 7, when the hooks or stems 5 are
secured in blocks 7 (sec Fig. 5) a series of such blocks 7 are laid, and secured, side by
side in the carrying frame 4, and form the equivalent of a continuous bar. Within
the space between each of the hooks or stems 5 is a circular cutter or knife 8, which
knives are mounted on a longitudinal shaft 9 and are free to move laterally along the
said shaft so as to ensure substantially correct position between the two books 5. 5 but
are caused to rotate with the shaft 9 by means of a key slot 10 formed therein, there
being a corresponding key 11 on the inside of each of the cutters 8, or vice versa.
shaft 9 is driven from any convenient "going part of the machine, by chain or gear
wheels.
The action is as follows:-As the pile loops 12 are formed they are by the guides 1
to which to, and fro, or lateral motion is given by the lever 15 which is caused to rock
on its fulcrum stud 16 by the peg wheel 17; a spring 18 giving the requisite motion
in the opposite direction, passed over the points of two, i.e. a pair, of the hooks or
stems 5 which are so shaped and arranged in relation to the arc of the circular
cutters 8 (see Fig. 3) that not until a series, or several loops are deposited on the
hooks or stems 5, will the first loop of the series be cut, and severed, the accumulation
of several loops beyond the range of action of the circular cutters 8, being designed.
to ensure the effectual "tying in" and securing together of the pile loops and the
knitted ground fabric before severance, the loops being held in the bend 13 of the
hooks or stems 5 until so much of the piece is knitted and "taken up" that the
loops are drawn, by the "taking up" action, down the incline 14 of the hooks or
stems 5, and so are brought in contact with the knives 8 which cut them, and as the
first or leading loops of the series are being severed by the cutters 8, a proportionate

page_text: number of new loops are being added, or placed upon the cranked hooks or stems 5.
In the provisional specification I describe the points of the cranked hooks or stems as
connected but in practice I have found it better to have all the said hooks, or stems
free at their points, and the knives between them as illustrated by the drawings.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
The improvements in machines for knitting and cutting pile fabrics wherein are
employed revolving circular cutters or circular knives working between cranked
hooks or stems such as illustrated in combination with the needle, sinkers, and
guides of a straight bar knitting machine as herein fully described.
