IMPROVE- MENTS IN MACHINERY OR APPARATUS FOR CUTTING GROOVES ON ROLLERS OR CYLINDERS
Year: 1885

page_text: COMPLETE SPECIFICATION,
I ALBERT FERDINAND LINK, of 8 Union Court, Old Broad Street, in the City
of London, Merchant, do hereby declare the nature of my Invention for " IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR CUTTING GROOVES ON ROLLERS OR
CYLINDERS," a communication from abroad by Victor Philippot, Frederick
Schneider, and Charles Jaquet, of 3 Guteleutegasschen, Strassbourg, Germany,
Manufacturers, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of my invention is to manufacture improved machinery or apparatus
for cutting grooves or channels on or in the external surfaces of cylinders or
rollers, such as case-hardened rollers for roller-mills, and cylinders or rollers for
other purposes.
In carrying out my invention, I fit a number of cutting tools in a circle, with
their cutting edges towards the centre of such circle. The number of tools and
their relative positions correspond with the number and positions of grooves
required to be made in the roller.
The tools are securely held in position and so mounted that they may be
simultaneously driven forward or drawn backward by means of nuts and screws
actuated by a rack and pinions; the rack being moved by hand or automatically,
as preferred.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is a plan; Fig. 3 is a section on the line CD of Fig. 1; and Fig. 5 is an
enlarged section on the line G H of Fig. 1. a a are the cutter bars, the front ends
of which are held in the grooves b₁ of the main ring b. C is a plate which is
bolted to the ring 6 by screws and nuts d. The outer ends of the cutter bars are
tapped to fit the nuts f, and these nuts are also tapped to fit the pinion nuts e.
g is a circular rack plate, having teeth g' which engage the teeth of the
ninions e e

page_text: Before commencing the work the tools a a are regulated by means of the
nuts ff. The depth of the cut is then regulated and controlled by the ring rack g,
which is slowly rotated either by hand or by suitable gearing. The cylinder to be
operated upon is then placed in a concentric position and gradually driven forward
against the cutter bars, which groove the cylinders as they proceed.
Fig. 2 is a plan of a modification of my invention, Fig. 4 being a section, on
the line A B of Fig. 2, and Fig. 6 a section on the line E F of Fig. 2. a a are the
cutter bars, b is the main ring, gå is the ring rack, the teeth of which gear with
the pinions e, to which screws f¹ are fitted, which actuate the carriages h. The
tools a are held in the carriages or tool holders h by set screws d', and the holders /
are hinged to the plate in order that they may recede from the work when it is
being withdrawn.
The apparatus may be fitted on a planing machine, or in a lathe, or other
suitable appliance for the purpose of operating upon cylinders or rollers.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
.
1. The manufacture and use of machines for simultaneously cutting any number
of grooves on or in case hardened or other cylinders or rollers, substantially as
herein before described and shewn on the drawings.
2 The general construction arrangement and combination of the several and
respective parts, together forming my improvements in machinery or apparatus for
cutting grooves on rollers or cylinders, substantially as herein before described and
shewn on the drawings.
