PROVISIONAL SPECIFICATION.
Apparatus for Testing and Indicating the Diameters of Wood Fluteä
Pressing Rollers of Wet Spinning Frames.
1, JAMES BARBOUR, of Falls Foundry, Belfast, Ireland, Machinist, do hereby
declare the nature of this invention to be as follows:-
In wood fluted pressing rollers for wet spinning frames, the flutes are of a
diametral pitch, that is, they have a certain number of flutes per inch diameter,
and to ensure accurate pitching of the flutes, great care has to be taken in turning
up the roller to the exact diameter previous to being fluted.
When the wood pressing rollers become worn, they are turned down and re-fluted
to the same number of flutes per inch diameter. In practice it is found the amount
taken off the diameter to allow of re-fluting, necessitates making a number of flutes
in the round decrease by a series of three flutes each time turned down and
re-fluting takes place, and it has hitherto been the custom to use a separate gauge
for each diameter of wood pressing roller in the series; i.e. from the largest
diameter to the smallest diameter, thus necessitating the keeping of a large number
of gauges, and to ensure the necessary accuracy of diameter, delicacy of touch in
the use of these gauges is requisite.
In order to dispense with the requirement for and use of numerous gauges
heretobefore necessary, and to simplify the operation of measurement, and to ensure
accurate measurement, I have devised apparatus which will measure any diameter
of roller, and by means of an indicating finger and dial, record a multiplied diameter
of such roller whereby any inaccuracy of diameter is proportionately increased, and
so made more apparent and readily detected.
Apparatus according to this invention comprises a dial divided into a series of
radial divisions representing the number of flutes in the wood pressing rollers, from
the largest diameter to the smallest diameter, these divisions being of such a space
that any inaccuracy in the diameter is multiplied.
Fixed to a true bed plate is a standard, and lugs or brackets, from which I carry
an axis for the pointer, also a driving pinion, and a pulley and weight. Other lugs
or brackets from the standard serve as guides for a vertical shaft or rod, on which
is a rack gearing with the pinion of the pointer, and at the lower end of the vertical
rod is a palm or foot. The roller to be measured is placed on the true surface or
bed plate, and on the vertical rod being raised in order to admit of the roller being
brought under the palm or foot for measurement, the rack on the vertical rod
operates the pinion and pointer, the latter indicates by the divisions on the dial
whether the roller is of the required diameter. On the roller being removed, the
motion of the axis is reversed by the pulley and weight, so as to return the pointer
to its normal position.

Pressing Rollers of Wet Spinning Frames.
I, 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 :-
In wood fluted pressing rollers for wet spinning frames the flutes are of a
diametral pitch that is they have a certain number of flutes per inch diameter. and
to ensure accurate pitching of the flutes great care has to be taken in turning up.
the roller to the exact diameter previous to being fluted.
As the wood pressing rollers wear they are turned down and refluted to the same
number of flutes per inch diameter, in practice it is found the amount taken off the
diameter to allow of refluting necessitates making the number of flutes in the round
decrease by a series of three flutes each time refluting takes place. And it has.
hitherto been the custom to use a separate gauge for each wood pressing roller in
the series i.e., from the largest diameter to the smallest thus necessitating a large
number of gauges and to obtain the necessary accuracy of diameter delicacy of
touch in the use of the gauges is requisite.
My apparatus is designed and is capable of measuring wood pressing rollers with
the largest number of flutes to rollers with the smallest number of flutes, thus
dispensing with the necessity of having a separate gauge for each of the intermediate
rollers between the largest and smallest diameters and at the same.
time any
inaccuracy in the diameter is magnified more or less as may be designed, it is thus
possible to ensure very effectively the diameter of the rollers and thus obtain
wood fluted pressing roller true to pitch diameter.
a
My apparatus consists of a dial divided into a series of divisions representing
the number of flutes in the wood pressing rollers from the largest diameter to the
smallest diameter, these divisions being of such a space that any inaccuracy in the
diameter is multiplied.
The dial is provided with pointer, and a palm attached to a rack which actuates
the pinion on the pointer moves parallel to a true surface on the apparatus, the
wood pressing roller to be measured resting on this true surface and the palm being
brought into contact with the roller the pointer will shew on the dial if the diameter
of the wood pressing roller is true to the number of flutes.
Such being the nature and object of this my said invention the following is a
complete description of same reference being had to the accompanying drawing in
which
.
Figs. I & II are side and front elevation of my apparatus.
1 is the dial divided into divisions 39 to 99 representing the, smallest diameter of
roller up to the largest diameter, the spaces in this, case being divided for a 28-per
inch diameter of wood pressure rollers; that is the spaces 39 to 99 in Fig. 2 are
made so as to measure wood pressing rollers with 28 flutes for every one inch of
diameter, 2 is the pointer which is made fast and moves with the pinion 3, which
pinion gears into the rack 4 the palm 5 is fixed to the rack 4 the rack being carried
and guided in the framing 6 so that the palm is constrained to move parallel to the
true surface 7.
The action is as follows when it is desired to ascertain if a roller is the accurate
diameter for fluting to say 84 flutes in the round.
The roller is placed on the true surface 7 and the palm 5 brought to bear on the
roller & by the connection of rack & pinion already pointed out the finger 2 will if
the diameter of the roller be accurate point to 84.

page_text: The spring 8 is applied to the rack pinion spindle for the purpose of counter-
balancing the weight of the rack & palm.
Having now particularly described and ascertained the nature of my said inven--
tion and in what manner the same is to be performed I declare that what I
claim is :-
The general construction arrangement and combination of parts constituting the
apparatus for testing the accuracy of the diameter of fluted rollers as herein fully
described and illustrated by Figs. I & II in the accompanying drawing.
