COMPLETE SPECIFICATION,
Improvements in Slubbing, Intermediate, and Roving Frames.
I, THOMAS FRANCIS DUNN, of Ashton, in the County of Providence and
State of Rhode Island, United States of America, Manufacturer, 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 fly-frames and speeders for winding
roves as they come from the roving rolls upon bobbins, and its object is to provide
an improved construction of the same, which shall possess superior advantages with
respect to efficiency in operation.
The invention consists in the novel construction and combination of parts,
hereinafter fully described and claimed.
In the accompanying drawing:
Figure 1 is a side elevation of a flyer constructed in accordance with my
invention;
Figure 2 is a perspective view of the flyer detached; and
Figure 3 is a detail longitudinal sectional view.
In the said drawing, the reference numerals 1 and 2 designate two rails, the
lower one of which, termed the spindle rail, is stationary, while the upper one
which is termed the bobbin rail, is vertically movable, carrying with it in its
movement, the bolster 3, which is secured thereto by a bolt 4 and nut 5. Secured
to the lower rail 1, is a bracket 6, in which is stepped the lower end of a spindle 7,
provided with a bevel gear 8, which meshes with a corresponding gear 9, on a
shaft 10.
The numeral 12 designates a sleeve through which the tube 7* of bolster 3
loosely passes, the lower end of which sleeve rests on a projection at the lower end
of the tube. This sleeve is provided with a bevel gear 13 which meshes with a
corresponding gear 14 on a shaft 14" journalled in a bearing 15, formed integral with
bolster 3. The upper end of sleeve 12 is provided with a rib 16 which is adapted
to engage in notches 17 in the lower end of a bobbin 18, so that said bobbin and
sleeve will rotate together. The parts so far described, form no part of my
invention, and may be of any ordinary or suitable construction.
The flyer or frame consists of a tube 19, adapted to fit on the upper end of the
spindle, formed near its upper end with a lateral shank or neck 21, provided with
two downwardly depending arms 23 and 24, one of which 23, is hollow, and formed
with a slot 25 extending from top to bottom thereof. The tube 19, above the neck
or shank, is formed with a transverse hole 26, communicating with the opening in
the top of the tube. At the lower end of the hollow arm is a stud 27, to which is
pivoted the presser 28, the upper arm 29 of which, is weighted or made heavier
than the lower end. This lower arm of the presser at its end is formed with a
flattened shoe 30, having a notch 31 in one side communicating with a hole 32 for
the passage of the roving. The presser, just below its pivotal point, is formed with
a bend 34, to center it with the hollow arm or barrel of the flyer.
The operation is as follows: The roving is passed down through the hollow arm
or barrel of the flyer, and passed through the notch in the shoe and connected with
the bobbin. Motion is then communicated to the bobbin and spindle through their
respective gears, both the bobbin and spindle rotating in the same direction, but
the former somewhat faster than the latter, and the bobbin being given an up and
down movement, as will be well understood by those skilled in the art to which the
invention pertains. As the flyer revolves around the bobbin, by the centrifugal
1

shoe on the lower end thereof to press inwardly against the bobbin. By means
well understood to those familiar with the art, the movement of the bobbin up and
down at each stroke is shortened, thus giving the taper at the ends.
By my invention, the flyers and speeders are made much lighter than those in
ordinary use, and the first cost thereof is much smaller. Again, in the old style of
flyers, when an end of the yarn broke, especially if the bobbin was over half full,
the arms of the presser hung down so far as to make it difficult for the attendant to
piece up the end, except when the flyers are in a certain position when the attendant
can conveniently get at the presser. However, as the frame seldom stops in such
position, the attendant is obliged to keep starting and stopping the frame until
the presser is in the proper place. With my improved flyer, the attendant can
piece the end up anywhere the frame stops, thus effecting a saving in time and
labor.
As before stated, the upper end of the presser is heavier than the lower end, so
that when the flyer revolves the centrifugal force will cause the upper end to fly
out, and cause the presser shoe to press against the bobbin.
Again, by my improvements, the hole in the barrel or hollow arm being straight,
there is less difficulty in passing the roving therethrough.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The combination with the revolving flyer having a hollow arm or barrel, of
the-presser pivoted thereto at a single point, substantially as described.
2. The combination with the revolving flyer, of the presser pivotally connected
intermediate of its ends to the lower end of the flyer, substantially as described.
3. The combination with the flyer having a hollow arm or barrel, of the presser
pivotally connected intermediate of its ends to said barrel and having its upper end
weighted or made heavier than the lower end whereby the centrifugal force of the
flyer causes said weighted end to be forced outward, and the lower end to be pressed
inward, substantially as described.
4. The combination with a flyer, having a barrel with a straight opening
therethrough, of the presser pivotally connected with said barrel, substantially as
described.
5. The combination with a flyer, of the presser pivotally connected therewith
having, a bend intermediate its ends for centering the same, substantially as
described.
6. The combination with a flyer, of the presser pivotally connected therewith
having a slot at its lower end and a hole with which said slot communicates,
substantially as described:
7. The combination with the rotating spindle and bobbin and the revolving flyer
having a hollow arm or barrel, of the vertical presser pivoted intermediate its end
to said barrel, and having its upper end weighted, whereby said weighted end is
forced outwardly by the centrifugal force and the inner end forced inwardly toward
the bobbin, substantially as described.
