PROVISIONAL SPECIFICATION.
Improvements in Drawing and Retaining Rollers of Wet Spinning
Frames.
I, ROBERT ARDILL, of Falls Foundry Belfast, Ireland, Mechanical Engineer
do hereby declare the nature of this invention to be as follows:-
This invention relates to the axles which carry the bosses forming the drawing,
or retaining rollers of machines for purpose aforesaid.
It is desirable that the length of axis extending across the intervening space
between each pair of said bosses should be coated, or covered by a metal not liable
to corrode through the action of moisture, or water thereon, and various devices
have been employed, such as casting the bosses, and intervening tubular lengths
upon the axis, then turning up the spaces, and bosses, and fluting the latter.
Or casting a tube of brass on the axis, then turning up the tube, and shrinking
on the bosses on such tube. In other cases the boss, and intervening length has
been cast in one, and then shrunk on the shaft, and turned up.
Such processes however entail considerable labour and cost.
Now according to this my invention in order to prevent the corrosion of the
axis (or axis and retaining or drawing bosses) carrying the drawing or retaining
bosses I electro.plate, or coat said axis with a non-corrosive metal, either before,
or after the drawing, or retaining bosses have been shrunk, or fixed upon their axis.
If the electro plating takes place after the drawing, or retaining bosses have been
fixed on the axis then the entire surface of suoh rollers ie. the axis, and bosses may
be electro plated. By the process of electro plating, or forming a metallic deposit
upon the axis, or rollers in lieu of casting the metal thereon, I obtain all useful
results, and advantages at less cost, and there is no liability of any slipping, or
displacement of the collars, and bosses as is the case when the old methods of
covering, or encasing the axis are practised.

COMPLETE SPECIFICATION.
Improvements in Drawing and Retaining Rollers of Wet Spinning
Frames.
I, ROBERT ARDILL, of Falls Foundry, Belfast, Ireland Mechanical Engineer,
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 relates to the axles. or- arbors which carry the bosses forming the
drawing or retaining rollers of machines for purpose aforesaid.
It is desirable that the length of axle or arbor extending across the intervening
space between each pair of said bosses should be covered by a metal' not liable to
corrode through the action of moisture or water thereon, and various devices have
been employed, such as casting from brass or other non-corrosive metal the bosses
and intervening tubular length upon the axle or arbor, then turning up the spaces
and bosses and fluting the latter.
Or casting a covering of brass on the axle or arbor, then turning up this covering
and shrinking bosses on to these covered axles or arbors.

page_text: In other cases the boss and intervening tubular length have been cast in one,
and after being bored and turned are shrunk on the axle or arbor.
Such processes however entail considerable labour and cost.
Now according to this my invention, in order to prevent the corrosion of the
axles or arbors carrying the drawing or retaining bosses, I electroplate or coat said
axles or arbors with a non-corrosive metal either before or after the shrinking or
fixing of the drawing or retaining bosses on these axles or arbors.
If the electroplating takes place after the bosses have been fixed on the axle or
arbor then the entire surface of such bosses and axles or arbors may be electro-
plated. By the process of electroplating or forming the metallic deposit upon the
axles or arbors or upon the axles and bosses in lieu of casting the, metal thereon I
obtain all useful results and advantages at less cost, and there is no liability of
loosening or displacement of the bosses as is the case when the old methods of
covering or encasing the axles or arbors are practised.
Having now particularly described and ascertained the nature of this 'my said
invention and in what manner the same is to be performed I declare that what I
clain is :-
The coating or covering of the axles or arbors or of the axles or arbors and bosses,
of wet spinning frames with a suitable non-corrosive metal by electro or like depositing
processes in lieu of the old methods herein recited. of covering said axles and bosses
and for the purpose set forth.
