I, WILLIAM SUMNER, of Spring Hill Iron Works, Waterhead, Oldham, in the
County of Lancaster, Spindle Maker, 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 principally for its object to provide an improved construction
of long collar bearing for the spindles of jack, roving, intermediate and slubbing
frames used in the preparation of cotton and other fibres which collar bearing
permits of winding more thread onto the bobbin, is more durable and causes less
wear of the spindle than heretofore has been the case.
And in order that my invention may be more fully understood I have caused to
he appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. 1 being an elevation and Fig. 2 a
longitudinal section of my improved collar bearing.
In carrying out my invention I form the lower part of the collar bearing of
cast iron, with a shoulder a adapted to rest upon the lug or arm or other suitable
part of the lifting rail and secured thereto in the usual or any other suitable
manner, as will be readily understood. The upper end of this bearing part I may
slightly recess internally, so as to form a shoulder a³ for the reception of a tube b
made of an alloy of metal, preferably of phosphorus bronze. This tube forms an
extension of the lower part of the collar bearing, and is secured thereto in any
suitable manner, say by solder, driven or screwed in as may be found most
convenient. The bore of the upper end of the tube 6 is slightly reduced and forms
bearing for the spindle.
In lieu of securing the said extension tube inside the said lower tubular part it
may be similarly secured outside thereof, as will be readily understood, the former
way is however preferable.
It will thus be seen that the tube b being made of an alloy of metal, will last
much longer than if made of cast iron, prevents the rapid wear of the spindle and
when old short collar spindles are worn in the traverse part of the collars, a fresh
hearing can be provided by fitting the said collar bearings with the extension
tubes 6 described, so that ordinary short collar bobbins may be used on the same.
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.
A collar bearing, for the spindles of jack, roving, intermediate and slubbing
frames used in the preparation of cotton and other fibres, consisting of a lower cast

latter is secured to and forms an extension of the lower cast iron part a, all
substantially as and for the purpose set forth.
