PROVISIONAL SPECIFICATION.
Improvements in or connected with the "Long Collars" of the
Spindles of Slubbing, Roving, and Intermediate Frames Used in
the Spinning of Textile Fibres.
I, JOHN MASON DAVENPORT, of Springfield House, Marland, Rochdale, in the
County of Lancaster, Machinist, do hereby declare the nature of this invention
to be as follows;-
-
My said invention has reference to the "long collars" used with the spindles
of slubbing roving and intermediate frames, to impart steadiness to the running
of the spindles. Such "long collars" provide two bearing surfaces for the
spindle, an upper and a lower one, the space between the bearings being some-
what recessed so as not to bear against the spindles. A disadvantage of the long
collars lies in their combined weight upon the lifting rail and the object of my
invention is to materially reduce such weight. To effect this I cut out portions
of the metal of the long collar between the two bearing surfaces leaving sufficient
to securely connect the upper and lower bearing together. The method of cutting
away such superfluous metal between the two bearing points may vary. I might
cut two oppositely disposed slots in the tube leaving two ribs of metal to connect
rigidly the upper and lower bearing, or more than two such slots might be cut in
the tube, care only being taken not to unduly weaken the tube. It will be
readily seen therefore that in a frame of say 120 spindles and upwards the
reduction of weight upon the lifting rail and corresponding lessening of the
pressure and power exerted upon the chains secured to the balance weights will
be considerable. A saving of power thus results, or an increased output is
obtained with a given power.

page_text: and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement and accompanying drawings; -
My said invention has reference to the "long collars" used with the spindles
of slubbing roving and intermediate frames, to impart steadiness to the running
of the spindles. Such "long collars" provide two bearing surfaces for the
spindle, an upper and a lower one, the space between the bearings being some-
what recessed so as not to bear against the spindles. A disadvantage of the long
collars lies in their combined weight upon the lifting rail and the object of my
invention is to materially reduce such weight. To effect this I cut out portions
of the metal of the long collar between the two bearing surfaces leaving sufficient
to securely connect the upper and lower bearing together.
My invention will be clearly understood from an inspection of the annexed
sheet of drawings referred to in the following description.
In the said drawings,
Fig. 1 represents sufficient of the spindle of a slubbing frame for the reader
to grasp my invention the long collar being shown in section.
Fig. 2 is a sectional plan of the collar on the line A B.
Fig. 3 shows an outside view of a long collar cut away at three points to
ensure lightness.
Fig. 4 is a sectional view of such collar taken on the line C D.
In carrying my invention into effect and as shown in Figs. 1 and 2 I form
the long collar a with two oppositely disposed slots b so that two ribs of metal c
are left to rigidly connect the upper and lower bearing portions of the long
collars.
Instead of cutting away portions of the collar at two points the tube may be
formed with three or more slots as shown in Figs. 3 and 4.
In some cases, only one slot may be made in the collar.
I do not confine myself with regard to the number of slots or to the contour
of such slots so long as an adequate amount of metal is left to maintain the
required strength of the tube a.
It will be readily seen that in a frame of say 120 spindles and upwards the
reduction of weight upon the lifting rail and corresponding lessening of the
pressure and power exerted upon the chains secured to the balance weights will
be considerable. A saving of power thus results, or an increased output is
obtained with a given power.
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
1 claim is-
1) As a means of reducing the weight of the "long collars" used in slubbing,
roving and intermediate frames, cutting away portions of such collars or forming
the same with slots in the manner and substantially as hereinbefore described
and shown.
2) The improved "long collar" for slubbing roving and intermediate spindles
constructed substantially as described and illustrated.
