I, JOHN DAWSON of Bower Green Shod, Florence Street, Leeds Road, Bradford in
the County of York, Worsted Spinner, do hereby declare the nature of this invention
to.be as follows:-
My object is to construct finishing and roving boxes in such a manner, that the
tension of the driving bands or tapes is the same throughout the traverse of the
bobbins, and to so run the latter that greater speed is obtained with less vibration to
the spindles than can be accomplished with the ordinary spindles and mode of driving
finishing and roving boxes.
I accomplish my object in the following manner :- -To the spindle rail of a finishing
box or roving box, I secure spindles, upon cach of which I place a tube similar to
what is used by cap and ring spinning and twisting frames, and drive the same by
bands or tapes which pass over the wharls of the tubes and guiding wharls on the
opposite side of the cylinder or pullies and over intermediate pullies so arranged, that
as the lifter plate raises and lowers the wharls and tubes with the bobbins thereon,
the intermediate pullies accommodate themselves to the constantly varying distances
between the cylinder or pullies and wharls, thus retaining an equal tension of the
bands or tapes in all parts of the traverse.
In case a machine is made with spindles on both sides, the guide wharls are not
required, the bands or tapes passing from the cylinder or pullies around the wharls on
the tubes at both sides of the machine and over the respective intermediate pullies, and
when the machine is arranged for rings, I place at the top of the spindles a shield for
keeping the fibre clear of the spindles and fix the rings to a stationary rail, the lifter
in both cap and ring arrangement giving traverse to the bobbins.

Improvements in Ring and Cap Finishing and Roving Boxes.
I, JOHN DAWSON, of Bower Green Shed, Florence Street, Leeds Road, Bradford,
in the County of York, Worsted Spinner 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 object is to construct finishing and roving boxes in such a manner that the
tension of the driving bands or tapes is the same throughout the traverse of the
bobbins; and to so run the latter, that greater speed is obtained with less vibration to
the spindles than can be accomplished with the ordinary spindles and mode of driving
finishing and roving boxes: and consists in mounting dead spindles to the spindle rail,
and placing on each spindle a tube driven by a band or tape which passes over an
intermediate pulley so arranged, that as the lifter plate rises and lowers, the inter-
mediate pulley accommodates itself to the constantly varying distance between the
driving pulley or cylinder and the wharl on the before mentioned tube, thus retaining
an equal tension.of the band in all parts of tho traverse.
I will explain my invention more in detail by aid of the accompanying drawings in
which Fig. 1 represents a section through such portions of a finishing or roving box
as are required to describe my invention, all the other parts not shewn being old and
in common use. Fig. 2 is a plan of the same partly in section, and Figs. 3 and 4
details of the intermediate pulley.
To the spindle rail A, I secure in the ordinary manner a series of dead or non-
rotating, spindles B, which may be provided for caps of the ordinary construction
similar to those used by spinning and twisting frames, or for what is known as rings
as shewn at C in the drawing; in either case, tubes are mounted on the spindles, and
at the bottom of each tube I secure a wharl D, around which passes a band or tape E.
The spindles B are mounted on one side of the machine only, each driving band or
tape driving two tubes in the following manner :-On the driving shaft F, I secure a
number of pullies G, around each of which passes a driving band or tape E, running
in the direction of the arrows around the wharls of two tubes to the back of the frame
around a guiding wharl H, then over an intermediate pulley J, back to the pulley G
thus completing its circuit."
The guiding wharls H are mounted on studs secured to the back rail K, and are
of such diameter that they may be recessed to receive spongy material such as felt
cloth, for absorbing and storing lubricant, by which the respective studs are constantly
kept lubricated.
The intermediate pulleys J are mounted on frames L, each of which is carried by
the longitudinal shaft M and provided with a projecting arm Lupon which is placed

page_text: a weight W, by which the respective pulley J is forced in the direction of the curved
arrow, thereby tightening the band or tape E, and allowing for the constantly
varying distance between the driving pulley G and the wharl D on the tube, thus
enabling the band or tape to retain the same tension throughout all portions of the
traverse.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, I'declare that what I claim is:
In a finishing or roving box, the combination of the driving pullies G, wharls D,
and intermediate pullies J, with the guiding wharls H at the back of the machine,
substantially in the manner and for the purpose described.
