PROVISIONAL SPECIFICATION.
Improvements in Knitting Machines.
We, WILLIAM HARRISON, Patentee and Manufacturer, and CHARLES WALLACE
HARRISON, Machinist, both of 48 Upper Brook Street, and 69 Hyde Grove
Chorlton-on-Medlock, Manchester, in the County of Lancaster, do hereby declare
the nature of this invention to be as follows:-
The improvements which are the subject of this invention relate to the circular
or cylindrical knitting machines such as are described in the Specification of the
Patent No. 1075 of 1891 in which latch needles are employed.
The object of this invention is to insure better action and adjustment, with greater
simplicity, to be more convenient to the operator, and to facilitate production of
superior work.
In this invention we effect the regulating of the dial post which holds the dial in
position, by means of a separate boss screwed to one of the clamps or other suitable
place other than the working base, which fastens the machine to the table, bench,
or stand; through the said boss we fit a thumb screw with a double collar at one
end, into which the bottom end of the dial post is fitted, said dial post being fastened
by a screw passing through it into an arm of the boss. When the thumb screw is
turned, it gives motion to the dial post for adjustment of the dial, the top part of
the said dial post holding the dial in position by coming into contact with a lug at the
underside of the dial. The fabric as it descends from the needles passes between
the top of the dial post and the lug underneath the dial, and as there is always a
great pressure and drag caused by this contact, the fabric requires considerable
weight or pulling by the hand to draw it between this binding contact. To obviate this
strain on the fabric, we fit either at extreme points or at the sides of the dial post
and the lug at the underside of the dial, a ball of hardened steel or other suitable
substance such as wood, india-rubber, pot, stone or the like, holding them in cavities
or sockets made respectively at top of dial post and the lug under the dial, with or
without caps having an aperture large enough to permit the balls to stand out or
beyond so that the work may pass between the balls, which protrude and easily
revolve in any direction.
These balls may be placed in other positions on the dial post and lug and fitted
in other convenient ways, the balls always showing an exposed surface a little
beyond the ball holder.
The fabric will pass between the balls in the dial post and the ball in the lug at
the underside of the dial which revolve or oscillate in the direction the fabric
descends from the needles, thus preventing excessive drag or strain upon the fabric.
In any convenient position we fit a rest for the ribbing arm when not in operation ;
we fasten by suitable means, or cast in one piece with the base or other part of the
machine different holdings either in the form of the letter H, or a square box with
four sides, with or without a bottom or stop, or with three sides and a small ledge,
or without the ledge, or with three sides and a well sunk in the base of the machine,
or four posts, a well in the base, a well with a division, or two brackets at suitable
distances into which the forked end of the ribber arm is dropped, or an open slit in
any part of the machine which will receive the ribbing arm, thus holding the dial in
a horizontal position, which position prevents the needles falling out of the ribbing
dial and facilitates inserting and regulating of the said ribber needles.
We also make a combination knife and yarn guide, the knife having a vertical or
curved fence at front side nearest the cylinder needles, this fence being slotted down

page_text: the centre as an ordinary slot V shaped or the edges being vertically parallel to
each other, or in either instance terminating with a round or oval hole, which may
have inserted a special hardened eyelet or edges of the slot or hole being hardened
by ordinary means: at the back side of the knife which is farthest away from the
cylinder needles, we fix a coiled or bent eyelet hook under which passes the yarn or
thread, this hook being fastened to the knife itself, keeps its relative position to the
slot or hole in the front fence, when the knife is either raised or lowered.
On the bracket through which passes the spindle or shaft of the driving wheel,
we place more than one boss, one above the other, thus allowing different diameters
of driving wheels being used when desired, which admits of an increase or decrease
of speed to suit different work.
On the cam plate of the ribber we fit a separate guard cam, placing it immediately
in advance of the ribber stitch cam, in order to prevent the needles being jerked out
of the dial or against the point of the stitch cam, by any undue impetus given by
the pushing out or action cam, caused by any jerky movement given by the operator
when turning the driving wheel.
At the four buffer corners which come into contact with each other when starting
or reversing the machine, as is constantly done while making the heel of a stocking,
we insert by suitable means, buffers made of wood, rubber, or any other suitable
substance for the purpose of deadening the noise which at present is objectionable
when the machines are worked in private families, or mills, and also rendering the
cam cylinder less liable to crack.
Dated this 5th day of December 1891.

Improvements in Knitting Machines.
We, WILLIAM HARRISON, Patentee and Manufacturer, and CHARLES WALLACE
HARRISON, Machinist, both of 48 Upper Brook Street and 69 Hyde Grove,
Chorlton-on-Medlock, Manchester in the County of Lancaster, 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 improvements which are the subject of this invention relate to the circular
or cylindrical knitting machines such as are described in the Specification of the
Patent No. 1075 of 1891 in which latch needles are employed.
The object of this invention is to insure better action and adjustment, with greater
simplicity, to be more convenient to the operator, and to facilitate production of
superior work.
We attain these objects by the means hereinafter described and as illustrated in the
accompanying sheet of drawings. In the several views therein shown, similar letters
refer to similar parts.
Fig. 1 is front view and Fig. 2 side view of the dial post attached to a cylindrical
knitting machine according to this invention and with balls fitted thereto;"
Fig. 3 is front view and Fig. 4 plan of one form of rest attached to the machine
for reception of the ribbing arm when not in operation ;
Fig. 5, is front view and Fig. 6, edge view of a combination knife and yarn
guide, and
Fig. 7, is an inverted view of the cam plate showing a separate guard cam.
In this invention we effect the regulation of the dial post a, Figs. 1 and 2, which
holds the dial in position, by means of a separate boss b, screwed to one of the
clamps or other suitable place other than the working base, which fastens the

page_text: machine to the table, bench or stand; through the said boss we fit a thumb screw c
with a double collar d at one end, into which the bottom end of the dial post a is
fitted, said dial post being fastened by a screw e passing through it into an arm of
the boss. When the thumb screw c is turned it gives motion to the dial post a for
adjustment of the dial h, the top part of the said dial post holding the dial in
position by coming into contact with a lug fat the underside of the dial.
The fabric as it descends from the needles passes between the top of the dial
post and the lug underneath the dial and as there is always a great pressure and
drag caused by this contact, the fabric requires considerable weight or pulling by
the hand to draw it between this binding contact.
To obviate this strain on the fabric, we fit either at extreme points or at the sides
of the dial post and the lug at the underside of the dial, a ball ġ and g' of hardened
steel or other suitable substance such as wood, india-rubber, pot stone or the like
holding them in cavities or sockets made respectively at top of dial post a, and the
lug funder the dial h, with or without caps, having an aperture large enough to
permit the balls g and g¹ to stand out or beyond so that the work may pass between
the balls which protrude and easily revolve in any direction.
These balls may be placed in other positions on the dial post and lug and fitted
in other convenient ways, the balls always showing an exposed surface a little beyond
the ball holder. The fabric will pass between the ball in the dial post and the ball
in the lug at the underside of the dial as they revolve or oscillate in the direction
in which the fabric descends from the needles, thus preventing excessive drag or
strain upon the fabric.
In any convenient position we fit a rest k for the ribbing arm j, when not in
operation; we fasten by suitable means, or cast in one piece with the base or other
part of the machine, different holdings either in the form of the letter H as shown
in Figs. 3 and 4 on drawing, or a square box with four sides with or without a
bottom or stop, or with three sides and a small ledge, or without the ledge, or with
three sides and a well sunk in the base of the machine, or four posts a well in the
base, a well with a division, or two brackets at suitable distances, into which the
forked end of the ribber armj, is dropped, or an open slit in any part of the machine
which will receive the ribbing arm thus holding the dial in a horizontal position,
which position prevents the needles falling out of the ribbing dial and facilitates
inserting and regulating of the said ribber needles.
We also make a combination knife and yarn guide as shown in Figs. 5 and 6, the
knife having a vertical or curved fence at front side nearest the cylinder needles,
this fence being slotted down the centre as an ordinary slot V shaped, or the edges
being vertically parallel to each other, or in either instance terminating with a
round or oval hole m, which may have a special hardened eyelet inserted therein,
or the edges of the slot or hole may be hardened by ordinary means; at the back
side of the knife which is farthest away from the cylinder needles, we fix a coiled
or bent eyelet hook n, under which passes the yarn or thread, this hook being
fastened to the knife / keeps its relative position to the slot or hole m in the front
fence, when said knife is either raised or lowered.
On the bracket through which passes the spindle or shaft of the driving wheel,
we place more than one boss, one above the other thus allowing different diameters
of driving wheels being used when desired which admits of an increase or decrease
of speed to suit different work.
On the cam plate p of the ribber, we fit a separate guard cam 9, as shown in
Fig. 7, placing said guard can immediately in advance of the ribber stitch cam r in
order to prevent the needles being jerked out of the dial or against the point of the
stitch cam by any undue impetus given by the pushing out or action cam, caused
by any jerky movement given by the operator when turning the driving wheel.
We do not desire to refer to, or describe the buffers, mentioned in the Provisional
Specification accompanying the application for this invention, the same having been
in use prior to that date, but

page_text: Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
In a circular or cylindrical knitting machine in which latch needles are
employed.
1st. The regulation of the dial post in the manner and for the purpose substantially
as herein before described.
2nd. The use of balls fitted in any convenient position in the dial post, and in the
lug under the dial, in the manner and for the purpose substantially as herein before
described.
3rd. The use of a rest for the ribbing arm when not in operation, either of the
form shown, or of other convenient form attached to the base or other part of the
machine in the manner substantially as herein before described.
4th. The use of a combination knife and yarn guide substantially as herein before
described.
5th. The employment of more than one boss for the spindle or shaft of the
driving wheel to pass through for the purpose and in the manner substantially as
herein before described.
Dated this 7th day of September 1892.
