PROVISIONAL SPECIFICATION.
An Improved Method of Construoting the Rollers for Wet Spinning,
Twisting, or Doubling Frames.
JOSHUA VALENTINE Eves of Forth River Mills Belfast Ireland Mill Manager
do hereby declare the nature of this invention to be as follows:-
The drawing and retaining rollers of wet spinning frames consist of a shaft of
wrought iron or steel with bosses or rings thereon which are fluted. These bosses
or rings are made of brass of suitable density and hardness and the spaces between
the rings or bosses-oxcepting the journals-aro covered with brass or other metal
not liable to corrosion.
The usual method of constructing these rollers is cither to cast the brass rings or
bosses and the shells between then on to the shaft in groups or carringes between
the journals or to cast a thin shell upon the shaft turn up the surface thereof and
shrink the bosses thereon.
This improved method of constructing the rollers for wet spinning frames
twisting or doubling frames is carried out by slipping or pressing on to the shaft a
tube of brass or other suitable incorrodible metal as tightly fitting as practicable
and shrinking upon this tube or tubes the rings or bosses, the contraction of which
is enough to tighten or secure the whole to the shaft. To facilitate the drawing on
of this tube when in one length, or tubes when in short pieces between the bearings,
the tube or tubes can be heated to make them expand.
When the tubes are put on the entire length of the shaft the requisite journals
are formed by removing the portion of the brass opposite the bearings.
Longitudinal grooves may be formed in the shaft and corresponding ribs be made
on the inner surface of the tabe so as to form a key and bed to prevent the tubes
and rings from turning round upon the shaft.
By this improved method of construction is obtained an incorrodible covering
for the spaces between the bosses as thin as is desirable and firmly attached to the
shaft.

An Improved Method of Constructing the Rollers for Wet Spinning,
Twisting, or Doubling Frames.
Joshua ValenTINE EVES of Forth River Mills, Belfast, Ireland, Mill
Manager, do hereby declaro 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 :-
The drawing and retaining rollers of wet spinning frames consist of a shaft of
wrought iron or steel with bosses or rings thereon which are fluted. Those bosses
or rings are made of brass of suitable density and hardness and the spaces between
the rings or bosses-excepting the journals-are covered with brass or other metal
not liable to corrosion.
The usual method of constructing these rollers is either to cast the brass rings or
bosses and the shells between them on to the shaft in groups or carriages between
the journals, or to cast a thin shell upon the shaft turn up the surface thereof and
shrink the bosses thereon.

page_text: This improved method of constructing the rollers for wet spinning frames twisting
or doubling frames is carried out by slipping or pressing on to the shaft a tube of
brass or other suitable incorrodible metal as tightly fitting as practicable and
shrinking upon this tube or tubes the rings or bosses, the contraction of which is
enough to tighten or secure the whole to the shaft. To facilitate the drawing on of
this tube whon in one length or tubes when in short pieces between the hearings the
tube or tubes can be heated to make them expand.
When the tubes are put on the entire length of the shaft the requisite journals
are formed by removing the portion of the brass opposite the bearings.
Longitudinal grooves may be formed in the shaft and corresponding ribs be made
on the inner surface of the tube so as to form a key and bed to prevent the tubes
and rings from turning round upon the shaft.
The drawing herewith shews a piece of a roller as used for wet spinning frames
and constructed after the manner herein described. Fig. 1 is an elevation and
Figs. 2 & 3 are cross sections thereof. a-a are the bosses or rings, b-b are the non-
corrodible tubes to form the covering of the shaft (c) between the bosses (a) except
at the journals (e'). Fig. 2 shewing the tubes (6) shrunk upon a plain shaft, and
Fig. 3 shewing the tubes (6) with longitudinal internal ribs to fit into corresponding
grooves in the shaft (c).
By this improved method of construction an incorrodible covering is obtained
for the spaces between the bosses as thiu as is desirable and firmly attached to the
shaft.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
(1.) In the construction of rollers for wet spinning twisting or doubling frames
the slipping or pressing on to the shaft of a tube or tubes which are subsequently
pressed into close contact with the shaft by shrinking on the bosses.
(2.) In the construction of rollers for wet spinning twisting or doubling frames
the slipping or pressing on to the shaft of a tube or tuber, which have ribs or
projections on their inner surface to fit into recesses formed in the shaft and
subsequently pressing the tube or tubes into close contact with the shaft by
shrinking on bosses.
(3.) The improved method of constructing the covering between the bosses of
wet spinning twisting or doubling frames us herein described and illustrated.
