Improvements relating to Knitting Machines.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings in the County of Middlesex, 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 relates to improvements in the blades or wings of knitting-wheels,
such as those commonly known as burr-wheels, sinker-wheels, or other wheels adapted
to be used in knitting-machines wherein such wheels are revolved by the cylinder-
needles which are brought into engagement with such blades by the revoluble
movement of the needle-cylinder, the needles entering the spaces between the
blades.
In certain kinds of work it is found desirable to prevent some of the needles
from entering such spaces; and various devices have been employed to fill such
spaces, or partially fill the same to limit the depth to which the needles can
enter.
Pieces of metal, known as "presser-bits," have been permanently secured to the
periphery of the wheel in such spaces, as in plush-burrs.
My invention consists in providing some of the blades of such wheels with a
presser-bit integral with the blade; and the object of my invention is to cheapen
the construction of wheels having presser-bits.
In some kinds of work it is desirable to provide a presser-bit in every third
space between the blades of a knitting-wheel, while in others presser-bits may be
required in every fourth or fifth space.
The blades of such wheels are usually inserted in peripheral grooves and made
detachable.
By having the bits secured to the individual detachable blades, the number
and position of the presser-bits can be easily varied as desired, upon the same
wheel.
In the drawings I have represented in Fig. 1 a view in side elevation of a
knitting-wheel, known as a plush-burr wheel, and a portion of the needle-cylinder
and needles of a circular-knitting machine, showing the relative positions of the
wheel and cylinder when in use, some of the blades of the wheel being removed
to better show my improved blade inserted therein.
Fig. 2 is a top plan view of the wheel detached, with the same arrangement of
blades.
Fig. 3 is a view in side elevation of one of my improved blades detached.
Fig. 4 is a horizontal section of the blade, taken on the broken line, 4-4, in
Fig. 3.
Figs. 5 & 6 are respectively face and edge views showing a modified form of
blade.
A is a portion of the cylinder, and A¹ knitting-needles secured thereon. B is
the knitting-wheel revoluble upon a fixed stud, B', in the usual manner. The wheel
is provided with peripheral grooves, B³, adapted to receive the blades, C, and C¹,
detachably secured therein in the usual manner.
The blades are so arranged upon the periphery of the wheel as to afford the
needle-spaces, C3, between them."
My improved blade, C¹, is made like the other blades, C, heretofore in use
except that a cut is made in the body of the blade and a portion struck up to
form the presser-bit, D, projecting sidewise from the face of the blade.

page_text: The portion struck up, is made of a width to approximately fill the space between
such blade and its neighbouring blade on that side in the wheel.
Such blade may be cut and struck up by suitable dies, such as are in common
use for cutting and striking up portions of sheet-metal.
D¹ is the aperture formed in the body-part of the blade by cutting and striking
up the portion forming the bit.
The form of the bit can be varied by changing the shape of the die by which
the bit is cut and struck up.
When desired, the blade may be formed from a blank having a projecting
tongue, D, as shown in Fig. 5, which tongue is bent up along the dotted line, D³,
to the position shown in Fig. 6, to form the bit.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is
As an improved article of manufacture, a blade for knitting-wheels having a
presser-bit integral therewith cut and struck up from the body part of the blade,
substantially as described.
