:
We, JOHN LOWMAN, of 140 Ormside Street, London, S.E., Engineer and
ALFRED ROSS, of 17 Water Street, Liverpool, in the County of Lancaster,
Accountant, do hereby declare the nature of this invention to be as follows :—
This invention has reference to the manufacture of cork ferrules, rings, and
other tubular articles, as cycle and other handles, and the like; and has for its
object more particularly to provide improved apparatus or machinery, by which
such articles can be accurately manufactured, and also at a rapid rate, and
consequently at little cost.
According to this invention, a tubular article to be made is carried on a mandril
and revolved at a suitable speed; and it is acted upon externally by an abrasive
surface revolving in a plane parallel, or nearly parallel, with the axis of the
mandril, and the article and mandril are adapted to be moved up to and away from
this abrasive surface by suitable mechanism; or, conversely, the abrasive part may
be so moved up to the article.
One convenient arrangement of mechanism for and mode of manufacturing the
articles by apparatus such as referred to, consists of employing a rotating diso
having upon its surface an abrasing material, such as glass, flint, or sand paper or
powder or the like, while the cork is carried in a frame adapted to vibrate or
Oscillate about a pivot or point of support. By this means, the article to be
shaped is moved up to and away from the face of the disc, by moving the frame
up to and away from it (the disc); and when it is completed, it is removed from
the mandril by an ejector device, moving parallel with the axis of the mandril,
which is conveniently moved to and fro by a simple handle, the return of the
ejector device being suitably effected by a spring; after a finished article is ejected
a fresh blank or raw ferrule or other article is put upon the mandril and operated
upon in a similar manner. In this form of apparatus, to render certain that the
diameter of the article produced shall always be the same, a screw, or other
adjustable device is provided on the vibrating mandril frame, and this stop comes
in contact with a fixed stop on a suitable part of the machine. By this means,
not only are articles of exactly the same diameter for a given "setting" secured,
but this diameter can be varied at will for making different sized articles.
A special construction and arrangement of parts, and means of performing the
several actions, of a machine having the characteristics above described, is as
follows:-
+
The grinding or abrading disc is mounted on a suitable axis, and revolved at a
suitable rate of speed; while the mandril is mounted upon a shaft, supported in
the vibrating frame above described, and standing above the level of the disc
shaft, and say to one side thereof, so that the movement of the abrading discitends
to keep the cork ferrule on its mandril, aud the head of this mandril is conveniently
made in clutch form to effect a firm grip between the mandril and the cork article.
The mandril shaft is driven from the motor shaft of the machine by bands or cords,
and through an intermediate pulley mounted on the same centre or lino of axis of
the pivots of the vibrating frame, so as to allow of free movement of this frame.
The limit of movement of the vibrating frame is effected by a stop device

page_text: consisting of an adjustable screw or stud in said frame, and a fixed stop or block
behind same,
in contact with which the screw. would come when the cork tube or
article has been reduced to the diameter desired. The ejecting device, in this
arrangement, consists of a shaft parallel with the mandril shaft, and mounted and
supported in the vibrating frame, and having at. its operative end a foot standing
at right angles, the end of which fits over the head of the mandril, so as to come
in contact with the rear edge of the tubular article when pressed outwards. This
rod and ejecting foot are adapted to be moved to and fro by a lever or handle
supported by the vibrating frame, so that the foot comes in contact with the back
edge of the ferrule, and removes it from the mandril in the ejecting action, whilst
the return action is effected by a spring mounted upon the back end of the ejector
shaft, its reaction being afforded by bearing upon a part of the vibrating frame.
The means of vibrating the frame to and fro, may suitably consist of a second
handle; in this case the operation of this machine is, that by one handle, the frame
and article to be shaped are moved up to the disc, by the movement of the other
handle, the manufactured article is ejected. While this particular form and mode
of action offer convenience and simplicity, the invention is not necessarily restricted
to it, or to any particular form as to, parts, so long as they contain or involve the
main characteristics of the invention above referred to.
The exterior form of the articles produced may be varied; a as for instance, it
may be parallel, or tapered, or curved or concave, as in the case of cycle handles.
To provide these different forms or shapes of articles, the surface of the abrading
dise will be set, or its shape male, accordingly; or, in the case, say of curved or
concave articles being made, the parts of the machinery carrying the vibrating
frame may be moved horizontally about a pivot, so as to change the position of the
article being made in relation to the disc; in which case, the disc itself, or its
surface, would, in most cases, be even.

Improved Machinery for Making Cork Rings, Ferrules, and other
Tubular Articles.
We, JOHN LOWMAN, of 140 Ormside Street, London, S.E., Engineer, and
ALFRED Ross, of 17 Water Street,, Liverpool, in the County of Lancaster,
Accountant,; 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 has reference to the manufacture of cork ferrules, rings, and
other tubular articles, as cycle and other handles, and the like; and has for. its
object more particularly to provide improved apparatus or machinery, by which
such articles can be accurately manufactured, and also at a rapid rate, and
consequently at little cost.
.
:
According to this invention, a tubular article to be made is carried on a mandril
and revolved at a suitable speed; and is acted upon externally by an abrasive
surface revolving in a plane parallel, or nearly parallel,, with the axis of the
mandril, and the article and mandril are adapted to be moved up to and away
from this abrasive surface by. suitable mechanism; or, conversely, the abrasive
part may be moved up to the article.
:
One convenient arrangement of mechanism for, and mode of manufacturing the
articles by apparatus such as referred: to, consists of employing a rotating disc

page_text: having upon its surface an abrading material, such as glass, flint, sand paper, or
powder, or the like, while the cork is carrieil in a frame adapted to vibrate or
Oscillate about a pivot or point of support. By this means, the article to be
shaped is moved up to and away from the face of the disc, by moving the frame
up to and away from it (the disc); and when it is completed, it is removed from.
the mandril by an ejector device, moving parallel with the axis of the mandril,
which is conveniently moved to and fro by a simple handle, the return of the
ejector device being suitably effected by a spring. After a finished article is
ejected a fresh blank or raw ferrule or other article is put upon the mandril and
operated upon in a similar manner. In this form of apparatus, to render certain
that the diameter of the article produced shall always be the same, a screw or
other adjustable device is provided on the vibrating mandril 'frame, and this
stop comes in contact with a fixed stop on a suitable part of the machine. By
this means, not only are articles of exactly the same diameter for a given
"setting" secured, but this diameter can be varied at will for making different
sized articles.
A special construction and arrangement of parts, and means of performing the
several actions, of a machine having the characteristics above described, is as
follows:
The grinding or abrading disc is mounted on a suitable axis, and revolved at a
suitable rate of speed; while the mandril is mounted upon a shaft, supported in
the vibrating frame above described, and standing above the level of the disc shaft,
and say to one side thereof, so that the movement of the abrading disc tends to
keep
the cork ferrule on its mandril, and the head of the maodril is conveniently
made in clutch form to effect a firm grip between the mandril and the cork article.
The mandril shaft is driven from the motor shaft of the machine by bands or
cords, and through an intermediate pulley mounted on the same centre or line of.
axis of the pivots of the vibrating frame, so as to allow of free movement of this
frame. The limit of movement of the vibrating frame is effected by a stop device
consisting of an adjustable screw or stud in said frame, and a fixed stop or blook
behind same, in contact with which the screw would come when the cork tube or
article has been reduced to the diameter desired. The ejecting device, in this
arrangement, consists of a shaft parallel with the mandril shaft, and mounted: and
supported in the vibrating frame, and having at its operative end a foot standing
at right angles, the end of which fits over the bead of the maudril, so as to come in
contact with the rear edge of the tubular article when pressed outwards. This
rod and ejecting foot are adapted to be moved to and fro by a lever or handle
supported by the vibrating frame, so that the foot comes in contact with the back
edge of the ferrule, and removes it from the mandril in the ejecting action; whilst
the return action is effected by a spring mounted upon the back end of the ejector
shaft, its reaction being effected by bearing upon a part of the vibrating frame.
The means of vibrating the frame to and fro, may suitably consist of a second
handle; in this case the operation of this machine is, that by one handle, the frame
and article to be shaped are moved up to the disc, by the movement of the other
handle, the manufactured article is ejected. While this particular form and mode
of action offer convenience and simplicity, the invention is not necessarily restricted
to it, or to any particular form as to parts, so long as they contain or involve the
main characteristics of the invention above referred to.
The exterior form of the articles produced may be varied; as for instance, it
may be parallel, or tapered, or curved or concave, as in the case of cycle handles.
To provide these different forms or shapes of articles, the surface of the abrading
disc will be set, or its shape made, accordingly; or; in the case; say of curved or
concave articles being made, the parts of the machinery carrying the vibrating
frame may be moved horizontally about a pivot, so as to change the position of
the article being made in relation to the disc; in which case, the disc itself, or its
surface, would, in most cases, be even.
The machinery by which the manufacture of hollow or tubular cork artioles are

page_text: made is shewn in the drawings hereto annexed, in which Figure 1 is a front
elevation, and Figure 2 a side elevation.
Referring to the drawings, a is a tubular article, the outside surface of which it
is desired to make circular, and to be rendered perfectly smooth. This article is
acted upon externally by a disc b having a glass paper, sand, emery, or like surface..
The disc b is mounted on the shaft c carried in brackets c, and the shaft e is driven
by a belt through pullies. The cork article a is carried on a mandril d on the
end of a shaft e, mounted in a vibrating frame f; this frame being itself supported.
by the centres g in the bracket supports h. The shaft e is rotated from a driving
shaft and a pulley, through the double pulley j, on the same centre as the
centre g, and another pulley k on the shaft e; these pullies being driven one from
the other by the bands
.
The cork article a has movement to and fro up to and away from the disc b, and
the frame frocks about the centres. g. This movement is given it by the handle m
on the frame; and the movement forward is adjusted by an adjustable screw n
which can be screwed more or less through the frame f, and a stop plate o, against
which the end of the screw end comes when the frame is pressed forward. By this
means, the size or diameter of the cork a is controlled, and accordingly as the set
screw n is screwed more or less in or out, so the diameter of the cork made will be
larger or smaller:
The action of the apparatus is, the revolving abrading disc b is rotated, and a
cork a (previously bored so that it can be placed on the mandril d), is pushed
firmly on the mandril, so that its back end engages with the points of the serrated
endel of the shaft e; and this shaft e being in rapid rotation, when the frame with
its cork in the rough is moved towards the disc b, so as to press the cork onto the
surface of the disc, then, by the rotation of the cork in the opposite direction to,
and in conjunction with the rotation of the disc, in the direction of the arrow
thereon, a true and perfectly smooth surface is put on the cork; and by the
position of the cork in relation to the disc shewn in the drawings, and by the
rotation of that disc endwise onto the cork, such cork is naturally pressed by
the rotation of the disc onto the serrations or points, el, and the cork is thus held
firmly in position and revolves against the action of the disc b. These double
actions soon grind the cork to the right size and with a smooth surface; and when
the cork is finished, an ejector p behind the cork a is moved outward by the
handle q and shaft r, the outer end of which shaft carries the ejector p; and by
moving the handle g, it acts upon one of the studs in the shaft r, and moves it
forward. The backward movement of this shaft is effected by a spring 7² at the
other end. After a hollow cork is finished, the frame is moved away from the
disc b, and the finished cork a is ejected by operating the lever g.
Although the invention thus far described has been set forth as applied to the
manufacture of hollow cork articles, yet it is to be understood that the improve-
ments hereunder may, by simple modifications of the means for supporting the
cork, be applied to the manufacture of solid corks or solid cork articles. And,
moreover, the invention is not limited or restricted to the particular forms or
constructions of parts of machinery shewn and described.
The form of the exterior of the articles may be rendered different, that is to say,
they may be parallel, tapered, or curved or concave, or of other suitable form by
making the surface of the disc 6 of auch a form; or, it may be effected by making
the bracket frame hadjustable on the bed of the machine, so that the shaft e may
*be moved to stand at an inclination to the surface of the disc b, instead of parallel
as shewn in the drawings. This latter method, or the former, of effecting this
end, may be adopted according to which is most convenient.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. Improved machinery for making cork articles or corks, consisting of a rotating

page_text: body b having an abrasive surface, and a rotating cork holding shaft or mandril
Bupported in a moveable or vibrating carrier, and revolved therein, whereby the
cork is acted upon by its own revolution, in conjunction with the revolving of the
abrading body; substantially as described.
2. In machinery for making cork articles or corks, the rotating abrasive disc b,..
and a revolving shaft e, having a mandril d carrying the cork n, and carried in the
vibrating frame f; all substantially as set forth with reference to and shewn in the
drawings.
3. The machinery for making hollow cork articles set forth particularly with
reference to and shewn in the drawinge.
