Improvements in Mechanism for use in Producing Roughened Metal
Surfaces, specially applicable in the Manufacture of Loom Take-
up Beams.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York,
Machine Maker, and JOHN MILLER of the same place, Manager, do hereby
declare the nature of this invention to be as follows, that is to say :--
In the construction of take-up beams for looms the object aimed at is the pro-
duction of such peripheral surfaces on said beams as will enable them, when in
operation, to draw or drag the piece of fabric being produced, continuously in
conformity or unison with the number of shots of weft or the quantity of filling
being thrown or put into said fabric, and that without in any way damaging, as
by cutting or otherwise, any of the fibres of which said fabrics are composed or
made.
To effect this object in accordance with our invention we firstly form these beams,
which are of metal to have perfectly straight and even peripheral surfaces-this
being done by any of the well known methods or processes-we then take them
and subject them to the operations of mechanism, hereinafter described, which
causes projections, more or less pointed, to rise and extend from said surfaces and at
suitable distances from one another, so that appropriately roughened surfaces or
surfaces with suitably formed dragging points or projections are formed for securely
laying hold of the fibres forming the fabrics when same are pressed into contact
therewith while when they are guided to travel from such contact said points or
projections readily allow them to do so.
The means or mechanism we employ for the production of the projecting pins or
points on the peripheral surfaces of the metal beams as above described, consists of
a disc having a serrated cutting edge, the serrations or cutting teeth of which are
formed so that when they are firmly pressed against the surface of the beam they
will dig or penetrate into it. This disc is mounted so that it may rotate freely in
its bearings or supports which hold it with its axis at an angle to the axis of the
beam upon which it is about to operate, and these supports are so arranged that by
screw or other mechanism they may be moved to press the said serrations against
the surface they are to penetrate with sufficient force to cause them so to enter.
The beam to be operated upon is mounted to rotate in its supports as between
the rotary and stationary spindles of a common lathe which answers the purpose
very well as in this case the tool carriage serves admirably as the means and
mechanism for supporting and operating the parts which carry the serrated cutter,
and rotary motion is imparted to it by any suitable mechanism, which in the case
of the lathe being used would be the well known driving mechanism.
As the beam is rotated each of the teeth of its serrated cutter, is brought in its
turn to enter and then to move out of the said beam's peripheral surface, and as its
axis is at an angle to that of said beam, their paths of motion are at such a variance
as to cause each of said teeth as it leaves the metal periphery to scoop a certain
portion thereof and turn or throw it up so that it will extend radially therefrom to
form the projection desired.
By suitable mechanism as by the screw of the lathes, lateral motion is given to
the rotary cutter so that as the beam rotates carrying with it said cutter, this
lateral motion of same carries it so that it operates over the entire length of said
Leam.

page_text: By mounting the rotary cutter in suitable bearings or supports, as say the tool
holder of a plane, and causing any flat surfaced piece of metal to move in contact
therewith as by being attached to the travelling table of said plane, pointed
projecting pieces might be formed thereon so that the piece of metal upon which
they are formed might be thus made similar to a rough file or rasp.

Improvements in Mechanism for use in Producing Roughened Metal
Surfaces, specially applicable in the Manufacture of Loom Take-
up Beams.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York,
Machine Maker, and JOHN MILLER of the same place, Foreman, do hereby
déclare 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, that is to say :-
In the construction of take-up beams for looms the object aimed at is the pro-
duction of such peripheral surfaces on said beams as will enable them, when in
operation, to draw or drag the piece of fabric being produced continuously in
conformity or unison with the number of shots of weft or the bulk of filling being
thrown or put into said fabric, and that without in any way damaging as by cutting
or otherwise, any of the fibres of which said fabrics are composed or made.
In accordance with our invention we firstly form the surfaces to be operated
upon or roughened, as the peripheral surfaces of the beams, perfectly straight and
even throughout, this being effected by any of the well known process such as by
the planing machine, milling machine or in the case of cylindrical articles as are
said beams, the ordinary turning lathes. These surfaces are then subjected to the
operations of a rotary cutter, hereinafter described, which causes projections more
or less pointed, to rise and extend from said surfaces with suitable spaces, inter-
vening between them, so that appropriately roughened surfaces or, in the case of
take-up beams, surfaces with suitably formed dragging points or projections are
formed for securely laying hold of the fibres forming the fabrics when same are
pressed into contact therewith while when they are guided to travel from such
contact, said points or projections readily allow them to do so.
We attain the object of our invention by the employment of mechanism illustrated
in the accompanying sheets of drawings, to which, by figures and letters reference
is made in the following description.
Fig. 1 is sectional end elevation of a common turning lathe with our improved
parts added.
Fig. 2 is illustrative of the parts shown by Fig. 1 but as seen from above.
Figs. 3 and 4 are side and edge views (enlarged scale) showing in detail certain
of the parts hereinafter described.
Fig. 5 is side elevation of a portion of a metal planing machine showing the
application thereto of our improved parts.
Fig. 6 illustrates the parts shown by Fig. 5 as seen from above.
The means or mechanism we employ for the production of the projecting pins or
points a (shown on an enlarged scale by Fig. 7.) on the prepared surfaces as above
described consists of a disc b (see Fig. 8) having a serrated cutting edge b', or this
disc b might have two serrated cutting edges and b as shown by Figs. 1, 2, and 4:

page_text: in which case when the edge b' is in use the other edge 6' is inoperative and vice
versá, in order to allow its positions to be altered when one edge is worn dull or
damaged.
The serrations or cutting teeth 6' and are formed of a somewhat pointed shape
so that when they are firmly pressed against the surface to be operated upon they
will dig or penetrate into it.
The disc is mounted so that it may rotate freely in its bearings or supports c
which are arranged to hold it so that its axis is at an angle to the axis of the
beam d or to the horizontal plane in which the metal surface e (see Figs. 5 and 6)
is placed when a cylindrical or flat surface respectively is under operation, and these
bearings c are arranged so that by screw or other. mechanism they may be moved
to press the serrations 6 6s against said surfaces with sufficient force to cause them
so to enter.
The beam d to be operated upon is mounted to rotate in its supports as between
the rotary and stationary spindles of a common lathe f which answers the purpose
very well, since in this case the tool carriage g serves admirably as the means and
mechanism for supporting and operating the bearing c while rotary motion is
imparted to said beam d (in the direction indicated by the arrow h) by the lathe's
usual mechanism as will readily be seen.
As the beam d is rotated each of the teeth of the cutter is brought in its turn
to enter and then to move out of the said beam's peripheral surface, and as the axis
of the cutter b about which it rotates is at an angle to that of said beam d, their
respective paths of motion are at such a variance as to cause each of said teeth 6'
as it leaves the metal periphery to scoop a certain portion thereof and turn or
throw it up so that it will extend radially therefrom. to form the projection a as
above described.
or
By the screw of the lathe, lateral motion is imparted to the carriage g so that as
the beam d is rotated as above described, its cutter b is by said carriage 9 carried
or moved lengthwise said beam d by which means the whole of its peripheral
surface is operated upon by said cutter b.
In order to enable the beam d to withstand the pressure of the cutter b, a stay or
bracket p is mounted upon the saddles of the tool carriage g, and on this stay are
mounted the antifriction rollers t and w which are in contact with said beam and in
position for firmly holding same.
By mounting the bearings c, which carry the cutter b, upon the tool holder k of
the common plane m, and causing any flat-surfaced piece of metal, as the piece e to
move into contact therewith by attaching same to the travelling table n of said
plane m, pointed projecting pieces might be formed thereon by reason of the variance
in the paths of motion in which said piece of metal e, and the cutter b travel as is
above described, so that the piece of metal e upon which these projections are formed
might be thus made into a rough file or rasp.
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. A disc having a serrated cutting edge or edges the same being arranged to
operate upon metallic or like surfaces substantially as specified.
2. A cutter of the shape described in combination with means for supporting or
holding same in order that it may operate upon flat or cylindrical surfaces substan-
tially as set forth.
3. A rotary disc having a serrated cutting edge, and means for holding or
supporting same in combination with the tool carriage and other parts of a lathe or
like machine for moving said cutter and the article upon which it operates in the
manner described substantially as and for the purpose specified.
4. The combination of a rotary cutter formed as described with a metal planing
machine the said cutter being mounted thereon and arranged to operate substan-
tially as set forth.

page_text: 5. The method of and means for producing roughened surfaces on cylindrical or
flat articles substantially as specified.
