page_text: We ROBERT HENRY LENDRUM, of Alma Mills, Thongs Bridge, Yorkshire, Manu-
facturer, and SAM MITCHELL, of the same place, Engineer, 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 has reference to circular knitting machines or stockinette frames, in
which wheels work or engage with the needles, and our improvements therein consist
in means to be employed, whereby the brackets for holding the operating wheels may
be more easily applied and adjusted than is now the case; and also means to be
employed for applying and more easily adjusting the pushbacks and their supports.
According to the present arrangement of apparatus, the brackets carrying the
operating wheels and pushbacks have been bolted to the segments of a circle bolted
or otherwise fastened to a ring or circular frame, the bolts or studs entering into
holes bored or drilled and "tapped" around the sides of the said segments; conse-
quently, when a change of pattern is required, or an alteration in the mode or
manner of knitting, or an alteration in the order of wheels, or additional wheels
required, the segments had to be thrown aside, and a new set obtained and bored in
the necessary places to receive the brackets and pushbacks.
Our invention consists in the use of a continuous circle or segments of circle formed
with two grooves for the reception of nuts, the bolts or screws of which pass through
the brackets and pushbacks, and are made secure by entering the nut placed within
the groove, and as the nuts are square, they are held rigid in the said groove during
the operation of screwing the bolt into the nuts. By this means the brackets carrying
the operating wheels and the pushbacks can be adjusted in any part of the circle,
thereby greatly facilitating any alteration in the order of wheels and position of the
pushbacks; consequently, a variety of designs may be made in the fabrics without
the trouble and loss of time hitherto experienced.
In order that our invention may be more fully understood, we will now make
reference to the accompanying sheet of drawings illustrative thereof, wherein Fig. 1
is cross-section of the outer circles of a knitting or stockinette frame, and Fig. 2 is
plan view thereof, shewing as much of a circle as is necessary to illustrate our
improvements, a are the upright needles, fixed to the circular frame b in the ordinary

and c is the outer circle, or segment of circle, to which are attached the
brackets d carrying operating wheels and also the pushbacks f. Our invention
consists in forming grooves g and h in the outer circle c for the reception of the nuts i
and j, into which nuts the ends of the bolts k and are screwed. It will be seen that
the nuts i and j can be slided in their respective grooves to any suitable position in the
circle, and that the brackets d and pushbacks f can be removed and changed when
required with great facility.
It will also be observed by those conversant with this class of machine that by the
formation of the grooves g and h, for the purpose of adjusting or altering the position
of the brackets and pushbacks, that a considerable saving of time and cost of material
is effected over the old method at present in use.
Having now described the nature of our invention and the manner in which the same
may be carried into practical operation, we would have it understood that what we
claim is :-
In a circular knitting or stockinette frame, the use of a continuous segment or
grooved circle for the ready application and adjustment of the brackets carrying the
operating wheels and the pushbacks in manner substantially as herein shewn and
described.
