PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Combs, and in Machinery and
Apparatus for the same.
We, THE ROSEMOUNT COMB MANUFACTURING COMPANY LIMITED, Manu-
facturers, and HENRY TYLER WORLING, Works Manager, both of the
Rosemount Comb Works, Aberdeen N.B. do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements connected with the manufacture of combs
and the arrangement of machinery or plant for the same, the object of the invention
being to cut a greater number of combs in a given time upon one machine or
apparatus than is possible with the existing apparatus and machines at present
employed.
In carrying our invention into effect, in place of the ordinary back and front
jaws now employed having two cutters on each, we mount four cutters upon
each of the jaws so that eight or more combs can be cut in place of four combs as
at present.
We employ the ordinary mechanism, levers and connections for giving motion
and for mounting the jaws upou the machine, but we make the head or holders of
the back and front jaws with duplicate blocks in which may be secured inde-
pendently four cutters or knives, the methods of attachment of the holding plates
and the adjustment for the same we employ in the manner now generally used for
single arm jaws.
We make the front jaw also with quadruple attachment devices for securing the
cutters.
In connection with our improved quadruple or multiple cutting back and front
jaws we employ an improved table upon which may be secured four or more
comb pieces which may be cut at the same time. We form the table with an
opening or channel down its central portion so that two comb pieces may be
placed upon the sides of the opening and two comb pieces also upon the outer
edges of the table, thus making eight combs in all when mounted upon the one table.
The channel down the central portion of our table we provide of a width and shape
suitable for the introduction of the hand for placing the horn or other material in
position upon the table, and we attach the table to the bed of the machine in any
well known manner.
We employ in connection with our multiple cutting jaws and table the ordinary
devices and connections at present employed for working in connection with
existing cutting engines and machines, modifying the shape of the table and the
arrangement of the cutter holders to suit the number of combs which are to be cut
beyond four as hereinbefore described when arranging our jaws and table for
cutting eight instead of four combs.

Improvements, in the Manufacture of Combs, and in Machinery and
Apparatus for the same.
We, THE ROSEMOUNT COMB MANUFACTURING COMPANY LIMITED, and
HENRY TYLER WORLING, Works, Manager, both of Rosemount. Comb Works,
Aberdeen, in the County of Aberdeen, 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 improvements connected with the manufacture of
combs and the arrangement of machinery or plant for the same, the object of the
invention being to cut a greater number of combs in a given time upon one machine
or apparatus than is possible with the existing apparatus and machines at present
employed.
In the accompanying drawings;-
Figures 1 and 2 illustrate plan and elevation respectively of the cutter jaws and
table, in a twin comb cutting machine according to our invention.
In carrying our invention into effect, in place of the ordinary back and front
jaws now. employed having two cutters on each, we mount four cutters A B upon
each of the jaws CD so that eight or more combs can be cut in place of four combs
as at present.
We employ the ordinary mechanism for giving a feed motion to the table
and perpendicular motion to the pivoting jaws from a superposed driving shaft, but
we make the head or holders of the back and front jaws with duplicate cutter
holding blocks in which may be secured independently four cutters or knives; the
methods of attachment of the holding plates and the adjustment for the same we
employ in the manner now generally used for single arm jaws.
In the figures of the drawing it will be seen that the cutter holders E of the front
jaw are secured in position by means of conical studs F, while clamping plates G
are provided which laterally bear against and secure the cutters A, and are firmly
held by the studs H. Provision may be made for the simultaneous adjustment of
the cutter holders E into a suitable inclination for producing the required taper in
the teeth of the comb such as a hand lever I which is pivotally connected by means
of a link J to the extremities of other levers K respectively provided upon the
holders E. Gauge plates L may be provided with two or more notches or recesses
into which the handle of the lever I may be placed, so that the holders may be
readily adjusted to standard tapers of teeth; and these plates also may be capable
of adjustment for alteration.
The cutters or knives B are secured to the rear jaw D by means of clamping
plates M N which slide within recesses O provided in laterally projecting arms P
and are held and adjusted to any desired inclination by means of studs QR the two
studs R holding the plate M while the stud Q presses the plate N'thereby effectively
holding the cutter.
In connection with our improved quadruple or multiple cutting back and front
jaws we employ an improved table S upon which may be secured four or more
comb pieces suitably held in longitudinal position correspondingly to the cutters,
which comb pieces are simultaneously cut: We form the table S with an opening
or channel T centrally so that two comb pieces may be placed upon the sides of the
opening and two comb pieces also upon the outer edges of the table, thus making
four comb-pieces in all when mounted upon the one table which produce eight combs
when cut. The channel down the central portion of our table we provide of a width
and shape suitable for the introduction of the hand for placing the horn or other

page_text: material in position upon the table, and we attach the table to the bed of the
machine in any well known manner.
We employ in connection with our multiple cutting jaws and table the ordinary
devices and connections at present employed for working in connection with
existing cutting engines, modifying the size and connections of the table and the
arrangement of the cutter holders to suit the number of comb pieces which are to
be cut beyond four as herein before described when arranging our jaws and table
for cutting eight instead of four combs.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner. the same is to be performed, we declare that what we
claim is
(1.) In comb cutting engines the provision of four or more cutters substantially
as herein before described.
(2.) In comb cutting engines the provision of a longitudinal channel or
channels in the feed table substantially as and for the purpose hereinbefore
described.
(3.) In twin comb cutting engines the improvements substantially as and for
the purpose hereinbefore described, and illustrated.
