PROVISIONAL SPECIFICATION.
An Improvement in Knitting Machines.
We, JOSEPH AUGUSTUS CLARING BURN of Liverpool Street, in the Town and
County of Nottingham, Hosiery Machinist, and HENRY CLARKE, Hosiery Manu-
facturer, of 39 Mathias Road Nottingham do hereby declare the nature of this
invention to be as follows:-
Our improvement relates to hosiery machines for the manufacture of lace hosiery
and is an improvement on that described in the Specification of Henry Clarke &
Thomas Mawby No. 6277 27th April 1888.
In the Specification referred to, only one pattern-wheel is used thus very little
modification is made in the pattern being knitted; now we propose to use two or
more pattern-wheels all of which are fixed to the same ratchet-wheel and revolve
together but only one at a time acting upon the truck connected to the sliding
block; this truck is capable of sliding upon an axil so that it may be brought
against any one of the pattern-wheels by a slide which also keeps it in position, the
slide may be moved either by hand or autimatically.
By the above method a pattern may be made entirely from one wheel or a portion
of two or more may be used as desired, thus a great variety of patterns may be
made without having to alter the screws in the cylinder plates.
Dated this 6th day of July 1891.

COMPLETE SPECIFICATION.
An Improvement in Knitting Machines.
JOSEPH AUGUSTUS CLARINGBURN Liverpool Street Nottingham Hosiery
Machinist and HENRY CLARKE 39 Mathais Road Nottingham Hosiery Manu-
facturer 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 :-
Our invention relates to knitting machines of the Cottin's type used for the
manufacture of lace hosiery and is an improvement upon the invention described in
Specification No. 6277 A.D. 1888.
In the knitting machine described in the Specification referred to, the pattern is
produced by a number of fashioning points which extend across, or partially across
the full width of the fabric, and are arranged in sets of one or more points according
to the pattern.
These points are fitted to slide in guides and are selected and pressed down to
act upon the work by perforated pattern cylinders, which are suitably mounted and
have horizontal, vertical and rotating movements, the horizontal motion being
derived from a pattern cam which also acts upon the point guides so that these and
the pattern cylinders are moved horizontally at the same time.
Our improvement consists in using two or more pattern cams any one of which
may be arranged to act upon the pattern cylinders and point guides thus giving us
increased facilities for varying the patterns.
In order that the application of our invention may be understood we have
attached hereto one sheet of drawings, in which
Fig. 1 is an elevation of the apparatus fitted with two pattern cams.

page_text: Fig. 2 a plan or the same, and
Fig. 3 a sectional elevation on the line A. A Fig. 1.
The same parts in all the figures are marked with the same reference letters.
The frame a carrying the appliance is supported from a fixed part of the machine
at one end of the same by a bracket and other suitable connections, and is fitted
with a slide c which is held towards one end of the machine by a spring d, and a
cam truck upon it up to one of the cams or 1, the revolution of which gives
motion to the slide c, and through the arms g g to the pattern cylinders and point
guides.
C
The cams and I are mounted upon an axle carried by the frame a and are
revolved by a ratchet wheel m which is actuated by a pawl n, lever o and rod p,
the latter being connected to a lever operated upon by a suitable cam.
The cam truck fis mounted upon an axle e and embraced by a fork f¹ which is
attached to a slider suitably guided in a brackets and moved to and fro to bring
the truck opposite either of the cams or by hand, or automatically, the latter
being done by connecting the slide to a lever which is acted upon by any of the
ordinary arrangements of pattern mechanisms.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
In knitting machines for the manufacture of lace hosiery by the apparatus
described in Specification No. 6277 A.D. 1888 the use of two or more pattern cams
for giving a horizontal movement to the pattern cylinders and point guides, sub-
stantially as shown and described in the accompanying drawings and Specifications.
