PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Compressing Metallic Bosses for
Wet Spinning Frames.
I, JAMES BARBOUR, of Falls Foundry, Belfast, Ireland, Machinist, do hereby
declare the nature of this invention to be as follows :-
This invention relates to apparatus employed for compressing metallic bosses for
wet spinning frames for spinning flax, or other like fibres.
It is most desirable that the drawing surfaces of the bosses, rings, or fluted
rollers, (usually made of brass) should be dense, and as free as possible from pores,
cracks or inequalities, as such detract from uniformity in the results, or yarn
produced.
According to this my said invention the bosses, or rings which are to be shrunk
upon their carrying shaft have their drawing surfaces condensed, and solidified
through the action of a series of pressure rolls. A convenient number, and
arrangement of the latter consists of three rolls, two of which are driven by
gearing arranged in a triangle with the requisite means for lifting one (preferably
by.levers) of the rolls for insertion of the boss, or ring to be operated upon, and
the necessary pressure is applied to the pressure rolls through the loose roll being
carried by a lever which being loosely mounted on a fulcrum stud enables the lever
to be moved, or turned, and the roll brought into contact with the ring, or boss to
be compressed, pressure being applied to this lever, and the roll carried thereby,
by means of screws, or weights which allow the amount of pressure to be regulated,
and adjusted. Two of the said rolls are provided with adjustable flanges so as to
accommodate various widths of bosses, or rings, and the said flanges confine the
boss at its sides or ends thereby preventing it from spreading laterally, or elongating
when being solidified by the pressure rolls.

Improvements in Apparatus for Compressing Metallic Bosses for
Wet Spinning Frames.
1, JAMES BARBOUR of Falls Foundry, Belfast, Ireland Machinist, 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 apparatus employed for compressing metallic bosses for
wet spinning frames for spinning flax or other like fibres.
It is most desirable that the drawing surfaces of the bosses, rings, or fluted
rollers (usually made of brass) should be dense and as free as possible from pores,
cracks or inequalities, as such detract from uniformity in the results, or yarn
produced.
. According to this my said invention the bosses, or rings which are to be shrunk
upon their carrying shaft have their drawing surfaces condensed, and solidified
through the action of a series of pressure rolls, a convenient number and arrange-
ment of the latter consists of three rolls, two of which are driven by gearing
arranged in a triangle with the requisite means for lifting one (preferably by
levers) of the rolls for insertion of the boss or ring to be operated upon, and the

page_text: necessary pressure is applied to the pressure rolls through the loose roll being
carried by a lever which. being loosely mounted on a fulcrum stud enables the
lever to be moved or turned and the roll brought into contact with the ring or
boss to be compressed, pressure being applied to this lever and the roll carried
thereby by means of screws or weights which allow the amount of pressure to be
regulated. and adjusted, two of the said rolls are provided with adjustable flanges
so as to accommodate various widths of bosses or ring, and the said flanges confine
the boss at its sides or ends thereby preventing it from spreading laterally or
elongating when being solidified by the pressure rolls.
Such being the nature and object of my said invention the following is a complete
description of same, reference being had to the accompanying drawings forming a
part of this Specification in which :-
Fig. 1 is an end elevation of my improved apparatus for purpose aforesaid...
Fig: 2 is a plan view of Fig. 1.
Fig. 3 is a sectional end elevation of the compressing rolls, with the boss or ring
compressed in position.
to be
Fig. 4 is a plan view of a part of the two rolls, which are driven by gearing
showing the construction and arrangement of the adjustable flanges for accommo-
dating various widths of bosses or rings to be operated upon.
Similar letters of reference designate corresponding parts in all the figures.
At. A and B. are two compressing rolls having screwed or chased bosses or
collars 3 formed or fixed on them, such bosses or collars having fixed or stationary
flanges O, O and adjustable flanges P, P or both flanges O, P may if desired be.
made adjustable, but by preference the flange O is a fixture as shewn. The
flange P consists of a loose ring bored out large enough to pass over the screwed
or chased part 4 of the collars or bosses 3 of the rolls A, B and these flanges P, P
are adjusted to suit the varying width of bosses by means of the nuts Q, or the
flanges P may form part of the nuts Q, these nuts QQ being held and prevented
from moving out of position by vibration of the rolls A, B by means of set screws 5,
lock nut or other means.
These rolls A and B are driven by means of a shaft C which passes from one.
end of the machine to the other and on the near or driving end of the said shaft C
the pinion E is fixed, the said pinion E gearing into and driving a wheel G fixed
to the roll B and on the opposite end of the shaft C is mounted another pinion E¹
which pinion El gears into a wheel H fixed to the roll A and the necessary power
may be communicated direct to the shaft C by means of the fast and loose pulleys D
and D' or by the intervention of gearing.
The compressing roll I which is made preferably without flanges is free to rotate
on its own axis or bearings in the levers J, Ji by which it is carried and the two
levers J and J¹ are mounted and free to turn on the fulcrum stud K the roll I being
pressed 'into contact with the boss or ring, S under operation by means of a nut N
cross bar M and eyebolt or screw L this screw-L.swinging on a centre 6 readily
allows of its being passed between the levers J, J when the pressure is to be
applied or of its withdrawal from the ends of the levers J, J' when the ring or
boss S-is to be removed, the counterbalance weight W facilitating the raising of the
levers J, J and the roll 1. The ring or boss S to be comprossed is placed on and
partly: between the two compressing rolls A, B and the roll I is then brought to
bear and press upon the ring or boss S the necessary pressure being put upon the
latter in the manner hereinbefore described and by moving the driving belt or strap
from the loose to the fast or driving pulley O power is applied to the shaft C the
rolls A, B.rotate causing the ring or boss S under operation to rotate by frictional
contact. This revolving of the boss or ring S under pressure gives an uniform
density and consolidation to the whole surface of the ring or boss S. the degree of
density varying according to the pressure applied to the roll I.
By use of above described apparatus the durability and efficiency of the rings
or bosses S is increased and a perfectly smooth surface free from pores or cracks
is obtained.

page_text: -
Although I have shewn and described as a convenient means of applying pressure
to the roll I by means of screwed eye bolt L it is obvious pressure may be applied
directly to the axis of the roller I.
Having now particularly described and ascertained the nature and object of my
Baid invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The general construction, arrangement, and combination of parts constituting
the improved apparatus for compressing metallic bosses for wet spinning frames as
herein fully described and as illustrated by Figs. 1 and 2 of the accompanying
drawing.
2. The adjustable flanged rolls A, B and roll I in combination and for the purpose
heroin described
herein described:
