PROVISIONAL SPECIFICATION.
Improvements in Delivery Rollers for Spinning, Twisting, and
Doubling, and the Method of Arrangement and Driving of
the same.
I, SAMUEL VICKERS, Gentleman, of 33, Bonner Road, London E., do hereby
declare the nature of this invention to be as follows:-
This invention relates to a method of arrangement and driving of the delivery
rollers of spinning, twisting, and doubling frames and relates more particulary, to
my prior invention No. 12758, 193.
Along each side of a central roller beam I place the usual fluted or continuous
rollers vertically one above the other, on adjustable bearings, these being the back
and bottom rollers. The front, or top rollers rest at a suitable angle, on the back or
bottom rollers, and are retained in position by an L shaped, or inverted bracket, one
leg of which is secured to and beneath the roller beam, the other leg being upright
in front and between the respective rollers. The uprights have short slots in cach
side to admit the pivots of the front or top rollers, so that each roller may be
quickly and separately lifted out and replaced without interferance with the general
arrangement, by these means the thread passes vertical and direct from the supply
bobbins to the spindles, the ends of the lower rollers, passing into the headstock are
fitted with suitable wheels driven by the pair of mitre wheels as explained and set
forth in my Specification and drawings No. 12758, /93.
For twisting or doubling, I employ the usual rollers mounted somewhat
differently, viz. -the continuous, or bottom are in front, and the top, or separate
rollers above, and between them and the roller beam.

COMPLETE SPECIFICATION.
Improvements in Delivery Rollers for Spinning, Twisting, and
Doubling, and the Method of Arrangement and Driving of
the same.
I, SAMUEL VICKERS, Gentleman, of 33 Bonner Road, Loudon, E., 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:-
These improvements relate more particularly to my Specification No. 12758
of 1893, in furtherance of the objects therein stated and described. They may also
be adapted to frames now in general use.
On each side of a central roller beam I mount the fluted, or continous rollers,
vertically, that is to say -tier above tier, the top (in this case front) or separate
rollers being retained in position by a right angle or shaped bracket one leg of
which is secured by adjustable screws to the underside of the roller beam, the other
leg being upright and furnished with slots to admit the pivots of the top rollers, and
answers the purpose of a saddle. By these means the nip of the rollers is obtained
by centripital pressure without weights or springs, and each top roller can be
instantly and separately removed or replaced, without interference with the general
arrangement. For spinning; the rollers are driven by wheels proportionate to the
requirement of the material under operation.

page_text: That my invention may be the better understood, I will refer to the following
description and the accompanying drawings, in which :-
:-
Fig. 1, (Sheet 1) represents a side elevation with rollers as arranged for twisting
and doubling.
Fig. 2. is a cross section shewing the rollers in position.
Fig. 3, a side elevation of the beam, with rollers and wheels arranged for spinning
or drawing.
Fig. 4, is a cross section of Fig. 3, with the rollers in position.
Fig. 5, is a diagram of the wheels and pinions.
Fig. 1, (Sheet 2) represents an alternative arrangement of the twisting or
doubling rollers.
Fig. 2, (Sheet 2), is a cross section of the same.
E, (Figs. 1 and 3, Sheet 1), is a mitre wheel and shaft (see also No. 12758
of 1893), on which are fitted the pinions a and e, gearing with the wheels b, c, d,
attached to the continuous rollers F, G, H. f, g, h, are the separate top (in this case
front rollers, II are inverted right angle brackets, or saddles, fixed to the
underside of the beam by regulating screws J J. jjare slots through which the
pivots of the top rollers f, g, are admitted, and allowed to press against the bottom
rollers F G. The centripital pressure of the rollers can be adjusted by the
screws JJ beneath the roller beam. No slots are required for the rollers 4, H.
For twisting or doubling I dispense with the upper and middle tiers of
rollers gh, G˚H, the wheels and pinion a, b, c, d, using shorter brackets or
saddles II (Figs. 2. Sheet 2) without slots, by fitting the mitre wheel E direct
on the end of the roller F, the top rollers f being of any suitable dimension.
I can obtain similar results by an alternative arrangement of the rollers viz.
By placing the top (in this case back) rollers f between the bottom roller F,
(Figs. 1, 2. Sheet 1) and the beam, their perifheries pressing against that of the
roller F, and their pivots supported by the projections 11, of the beam as represented
in Figs. 1 and 2 (Sheet 1) (see also No. 12758 of 1893).
Any suitable creel, or system of spindles may be used with this invention.
I will now describe the action or performance of the foregoing.
spinning:-
:―
As to
By the motion of the wheels and pinions a, b, c, d, e, (Figs. 3 and 4, Sheet 1), the
thread or yarn is drawn perpendicularly downward between the rollers f, g, h,
and F, G, H, from the supply bobbins to the spindles, whilst the twist runs
immediately close up to the nip of the rollers, thereby producing better results.
Additional tiers of rollers may be used. As to doubling
In a similar manner the threads are drawn and twisted by the more direct action
of the mitre wheel E upon the rollers F. (Figs. 1, 2, Sheets 1 and 2). The usual
wire guide rail not being required.
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. The method of mounting, and arrangement of the rollers F, G, H, and f, g, h,
by means of the brackets or saddles II with or without slots,-substantially as
described and represented.
2. The driving of the rollers F, G, H, by proportionate wheels and pinions a, b,
c, d, e, substantially as described, and shewn in the accompanying drawings.
3. The driving of the twisting rollers F, f, by the more direct action of the mitre
wheel E, substantially as described.
4. The use of the foregoing improvements separately, or together as substantially
described and illustrated by the accompanying drawings.
