IMPROVEMENTS IN CAP SPINNING AND TWISTING FRAMES
Year: 1885

page_text: I, ARTHUR ANDERTON of Victoria Mills, Cleckheaton, in the County of York,
Spinner, do hereby declare the nature of my invention for IMPROVEMENTS IN CAP
SPINNING AND TWISTING FRAMES to be as follows:-
This invention relates to certain improvements in cap spinning and twisting
frames; and has for its object, the mounting of the driving cylinder in such a
manner, so as to obtain an uniformity of tension on the spindle driving bands at
all positions in the constantly varying relative height between the cylinder and
wharls on the spindles; this I accomplish in the following manner:
I mount in rigid journals placed parallel to the cylinder, an additional shaft
extending the length of the frame, to which rotary motion is imparted by gearing
in connection with what is commonly called the lifter heart shaft. Upon the
additional shaft I secure eccentrics, which are connected to the journals of the
cylinder shaft by rods; so that, on the before named shaft and eccentrics revolving,
the cylinder journals are caused to move backwards and forwards in curved slots
formed in brackets supporting the said journals.
The centre of the cylinder is placed below the wharls on the spindles, and the
slots in the brackets cut to a curve having the same radius as the distance between
the centre of the cylinder and the wharl..
The lifter plate on one side of the frame, is as usual on the top when the one on
the opposite side is at the bottom; and the cylinder, moving in the curved slots
in the manner described, is regulated so as to travel towards the spindles on that
side of the frame on which the lifter plate is rising, and when at the top to travel
in the opposite direction, by which the bands at both sides of the frame are kept
at an uniform tension.

page_text: I ARTHUR ANDERTON, of Victoria Mills, Cleckheaton, in the County of York,
Spinner, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN CAP SPINNING AND TWISTING FRAMES 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 certain improvements in cap spinning and twisting
frames, and has for its object, the mounting of the driving cylinder in such a
manner, so as to obtain an uniformity of tension on the spindle driving bands, at
all positions in the constantly varying height between the cylinder and wharls on
the spindles; and consists in mounting the cylinder journals in slotted brackets,
or on radiating arms carried by studs, and connecting the cylinder journals or
shafts to eccentrics secured on revolving shafts mounted in rigid journals, and
actuated by gearing from the heart shaft, or by any other convenient shaft of the
frame.
In the accompanying drawings, Figs. 1 and 2, shew respectively such portions
of the end elevation and plan of a spinning frame as are required to explain one
method of carrying out my invention. Fig. 3 is an enlarged detail of the slotted
bracket for supporting the cylinder journal. Fig. 4 is a longitudinal section of the
same, Fig. 5, is an end elevation of the frame shewing the cylinder suspended by
arms, Fig. 6, is a plan of the same, Fig. 7 shews the cylinder supported by arms
and Fig. 8, shews the cylinder supported by arms extended below the studs on
which they are mounted. In all the figures similar letters indicate similar parts
where they appear.
The frame end is indicated by the letter A, to which is secured at each end of
the frame a bracket B. formed with a curved or straight slot B¹ in which is
mounted a sliding journal D, of the cylinder C. To the frame I also secure rigid
journals, and mount therein the additional shaft S, extending the length of the
frame, to which rotary motion is imparted by gearing F, connecting the said shaft
to what is commonly known as the heart shaft G.
Upon the shaft S, I secure eccentrics E which are connected by rods R to the
sliding journals D, or to the cylinder shaft revolving therein, so that by the shaft S,
revolving; the eccentrics E, cause the sliding journals D, to move backwards and
forwards in the slots B¹; the eccentrics being so adjusted, as to cause the sliding
blocks and cylinder to travel towards the spindles on that side of the frame, on
which the lifter plate is rising; and when the plate arrives at the top, to travel in
the opposite direction, by which the bands on both sides of the frame are kept at
an uniform tension.
"
The slotted bracket may be dispensed with, and my object accomplished by
securing to each frame end, a stud H, for suspending an arm J, in which is formed
a journal for supporting the cylinder C. The journal of each arm or the cylinder
- shaft is connected to the eccentrics E on shaft S, which cause the cylinder to move
backwards and forwards as before described, or the cylinder may be supported by
arins K, as shown by Fig. 7, and connected to the eccentrics as before described.

page_text: These arms K may be extended as shewn by Fig. 8. to below the cross rail, in
which case, I mount the shaft S, in rigid journals below the cylinder C, and secure
the eccentrics thereon to work within a fork opening formed in the bottom portion
of each arm at K¹. The eccentric shaft S, is driven from the heart shaft, and on
revolving, moves the arms K and cylinder C, backward and forwards the required
distance to compensate for the slackening and tightening of the bands as the lifter
plate descends and ascends.
By connecting the cylinder journals or shaft to the eccentric shaft S, mounted in
fixed journals as before described; the tension of the spindle driving 'bands L, is
not affected by the main driving belt, the eccentrics keeping the cylinder from
vibrating, thereby keeping the bands at an uniform tension.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The moving of the cylinder C, backwards and forwards substantially in the
manner shewn and described and for the purpose herein set forth.
