Improvements in Spinning, Twisting, and like Machines used in the
Treatment of Fibrous Substances.
I, ANDREW COWLES ALLGOOD, of Henderson, in the County of Vance, and State
of North Carolina, United States of America, Mill Superintendent, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
This invention relates to that class of spinning and twisting frames in which
a vertical movement in relation to the spindles is imparted to the ring-rail carry-
ing the travellers, and the invention particularly relates to that type in which.
the thread-guides follow the motions of the ring-rail.
23
The object of this invention is to produce a simple and inexpensive attachment
for spinning-frames, to take the place of the thread-board in common use, said
attachment providing for the automatic raising and lowering of the thread-guides,
to any distance from the end of the spindle or bobbin at each waive" of the
traverse or ring-rail. By means of this invention, the separators can be entirely
done away with, for the reason that when the ring-rail is at the lower or bottom
part of the bobbin, the guide-eyes can be adjusted so as to come as near the end
of the spindle or quill as desired, and remain until the quill is filled to any de-
sired point, and then automatically rise with the ring-rail, until the quill is full.
This traverse motion prevents the yarn from "ballooning or whipping together
and breaking the ends down when the ring-rail is at the bottom or lowest point;
and the upward "waive" of the guide-eyes when the quill is being filled, allows
the yarn more space between the guide-eyes and spindles, which gives less ten-
sion on the yarn. The same applies to both warp and filling frames. This traverse
motion of the guide-eyes makes it possible to use a traveller of much less weight.
because the guide-eyes, being brought nearer to the end of the bobbin when the
ring-rail is at the bottom, and raised when the ring-rail is at the top, gives less
and a more even tension on the yarn, and will give a more even twist and prevent
a large percentage of the ends from breaking down, thus reducing the scavenger
waste and reducing the cost of labor and production. Moreover, by means of this
invention, yarns can be spun much softer, on account of less tension and the more
even twist. And finally, the attachment can be applied to spinning-frames now
in use, and in place of the wooden thread-boards now on such old machines.
To these ends, the invention consists in the construction and combination of
parts substantially as hereinafter described and claimed.
In the accompanying drawings,--
Figure 1 represents a perspective view of so much of a spinning-frame as is
necessary to illustrate this invention, the present improvel attachment being shown
as connected therewith.
Figure 2 represents a detail view, showing the parts in a different position.
Figure represents a detail section, on a vertical plane, through the cam and
the unner cad of the lifting-rod shown in Figure 1.

page_text: Figure 4 represents an enlarged detail view of the upper end of one of the thread-
eye lifting rods and the parts carried thereby.
Figure 5 is a view similar to Figure 4, but showing some of the parts in
different position.
Similar reference characters indicate similar parts throughout the several views.
The spindle-rail of the frame is represented at a', and the bottom rail at b, these
rails being of the conventional or any preferred type. Secured to said rails are
brackets e, which form guides for the lifting-rods d, of which there may be any
number to properly support the thread-eyes and their rod presently described.
The upper end of each rod d is provided with a slotted head e, which forms a
bearing for the guide-wire rod f extending over the ring-rail a from end to end
of the machine. Secured to the said rod f, and located in the slot of each head e,
is a cam g having two shoulders 1 and 2 adapted to alternately engage the bottom
of the slot in the head e, according to which direction the rod f may be turned to.
These shoulders 1 and 2 are so spaced as to permit of a rotation of the rod f slightly
more than one-fourth of a circle. At suitable points, according to the space between
the spindles, the rod f is perforated to receive the guide-wire studs h, each of said
studs being jointed to provide an outer arm which may be turned upward and
backward, as indicated in the drawings, each of said arms being provided with
a thread-eye k.
From this description, it will be readily understood that the rod f may be rota-
ted to throw all of the eyes back and hold them in position for doffing, and may
be returned so that the guide-wire studs will be in a horizontal position for spin-
ning. Owing to the joints in the studs hi, the outer ends thereof, the arms i, may
be turned upward to enable individual bobbins to be removed for piecing-up
ends, etc.
The lower end of each rod d is provided with a foot 7 adapted to be engaged
by a stud m secured to the lever or arm n, which lever n may be of the ordinary
type employed for lifting the ring-rail, through the medium of the usual rods o.
Preferably the stud m is adjustably secured in a slot formed in the lever n, in
order that the amount of elevation imparted to the guide-eye rod may be adjusted.
This also provides for adjusting the speed of movement of the rod by varying the
distance of the stud m from the pivot or fulerum of the lever n.
Each rod is provided with an adjusting collar p, adapted to contact with the
upper surface of one of the brackets c, to limit the downward movement of the
rod, and thus limit the lower position of the thread-eyes.
The rods are of such length that their lower ends, the feet 7,--will not rest
upon the studs m during the lower portion of the movement of the levers n, the
downward movement of the rods being limited as above statel, by the contact
of the collars with the brackets, this resting of the collars on the brackets
continuing until the studs m make their lowest point and return, and come in
contact with the feet of the lifting-rods. Each foot 7 may be adjustably secured
to the rod by means of a set-screw, as indicated, to aid in the adjustment of the
limit of the highest point to which the guide-eyes may be moved.
It is to be understood that the operation of the spinning-machine will be as
usual, and that the upper traverse of the levers n will, through the medium of
the lifting-rods, elevate the guide-wire rod, and prevent the yarn from ballooning
or whipping together, and preserving the uniformity of tension, as above de-
scribed. My attachment provides for dispensing with all woodwork connected with
thread-board and guide-wires, thereby leaving the space between the steel rolls
and the ends of the spindles or bobbins almost entirely open, thus allowing all
dirt, leaf, naps, etc., to drop directly to the floor, and doing away with the wiping
and cleaning common to wooden thread-boards now in use. Besides saving the
labor of cleaning the thread-board, cleaner yarn is produced, because of the dirt
leaf, etc., being allowed to drop directly to the floor instead of being caught by
the thread-board, where heretofore a certain percentage of it would be wiped off

page_text: or blown off and catch on the yarn, causing lumps and dirty places, and occasion-
ally making a break in some future process of manufacture, and leaving imper-
fections in the goods.
The described invention is equally applicable to twister-frames as to spinning-
frames, without departing from the spirit of the invention.
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;-
1. A spinning-machine attachment comprising in its construction a plurality
of rods adapted to reciprocate vertically and having adjustable stops for limiting
their downward movement, a guide-wire rod supported by said vertically movable
rods and carrying a plurality of guide-wire studs, means for reciprocating the ver-
tical rods simultaneously with and during the upper portion of the waive of the
ring-rail, and means for adjusting the amount of elevation and speed of move-
ment of the said vertical rods.
2. A spinning-machine attachment comprising in its construction a plurality
of rods adapted to reciprocate vertically and having adjustable stops for limiting
their downward movement, a guide-wire rod supported by said vertically movable
rods and carrying a plurality of guide-wire studs, each of said vertically movable
rods having a foot at its lower end, means including levers for vertically recipro-
cating the ring-rail, said levers being provided with slots, and projections adjust-
able in the slots of said levers for engaging the feet carried at the lower ends of
the said vertically movable rods.
3. The combination with the rods having slotted bearings at their upper ends,
of the guide-wire rod f fitted to said bearings, a cam located in one of the slots
of the bearings and secured to said rod f, said cam having stop-shoulders 1 and 2,
and a plurality of jointed guide-wire studs passing through said rod f, substan-
tially as and for the purpose specified.
