'IMPROVEMENTS IN
LÉON VALLET, of Liverpool, in the County of Lancaster.
AND RELATING TO SIMULTANEOUSLY EXTERNALLY AND INTERNALLY TURNING,
BORING, GROOVING, CUTTING, AND OTHERWISE FORMING AND SHAPING WOOD
AND OTHER MATERIALS, AND MACHINERY EMPLOYED THEREFOR"
My Invention has for its object the simultaneous performance of the various
actions required for forming articles, such as internal and other stoppers for bottles,
bobbins, circular boxes and other similar articles, namely, the simultaneous external
and internal turning, boring, grooving, cutting, and otherwise forming and shaping
wood and other materials into such articles.
A machine for carrying my Invention into practice, and constructed according
to my Invention, consists of a hollow shaft or spindle, which spindle is slightly
smaller at the front end near the cutting tools than at the other end, and at such
smaller end is cut lengthways with saw cuts about two inches in length, so as to
divide the spindle and form a sort of spring, which may be regulated by a sliding
ring, and which holds and keeps steady the material to be worked, which passes
through the hollow shaft or spindle, the inside of which may be circular or square,
or of other suitable form to pass in and through the piece of material to be worked
or manufactured. The wood or material to be manufactured or formed into, say,
internal stoppers for bottles, may be in the form of a spindle of about three or four
feet in length, of circular or square section, and corresponding with the hole of the
hollow spindle. This length of wood or other material is placed inside of the
hollow spindle, and then by a mechanical contrivance, hereafter described, is forced
forward through the hollow spindle in gauged lengths to suit the article being

page_text: manufactured. The hollow spindle is revolved at a speed to suit the material
being cut. The cutting tools are formed and disposed on a moveable rest in such
a manner as to cut the external part of the object being manufactured. The tools
are placed on one or both sides of a laterally moving slide rest, by moving which
forwards and backwards the tools are brought against the material, one set of
tools being used to take the first or rough cuts, the other set of tools being
used to take the finishing cut from the revolving material. When it is required
to bore or cut interior holes in the object being manufactured, or to groove or
undercut a part or the whole length of the article, this oporation is performed by
an end boring tool or cutter, against which the article revolves. This end boring
tool is brought into operation by a cam motion or a cam and springs. This cam is
fixed on and worked by the lateral movement of the slide rest, which brings or
slides first the boring tool lengthways, to bore part or the full length of the object
to be manufactured. This is accomplished by the forward movement of the slide
rest, a further movement of which causes a projection on the slide rest to come in
contact with and cant the boring tool, which is spring held, to one side, so that the
tool will cut internally a larger diameter than the hole through which it entered,
or in other words undercut or hollow out the article. The boring tool is shaped on
one side to correspond with the form of the internal hole being bored and undercut
-or-grooved. This inside cutting is accomplished simultaneously with the external
cutting, and at the same time a gauged tool cuts the length of tho material-off the
unmanufactured piece, namely, it cuts off the manufactured article which drops
down. Then by means of a mechanical-rack-contrivanco-or-like-gauged advance_
gear, against-which-the-end-of_the_material runs on a suitable lathe centre, such
material is brought forward into a position to be again operated by the cutting
tools, and so on, until the length of wood or other material is exhausted and
manufactured into the article being made. A fresh piece of wood or other material
is put in the hollow spindle and pushed through by the rack or other gauge con-
trivance, and worked off into the articles which the machine is set to manufacture.
In some cases when the article to be manufactured is to be bored and grooved in
part or full length, the first piece of the material is cut to shape externally, and
then by the rack or gauge notion is moved forward to be bored and internally cut.
Simultaneously with this latter action a second article is being externally formed
on the advanced material. At the end of each operation a side tool cuts off the
finished article, which drops down, and so on, until the length of material is
exhausted.
In the case of internally cutting, the last piece of the material cannot be finished
inside without altering the motion of the cutting tool, but this last piece may be
finished by a hand tool especially arranged for this purpose, without altering the
disposition of the cutting and boring tools in the machine.
The method of turning wood and other material according to my Invention will
be found to effect a great saving of time and material over the most approved
known processes of turning or boring. According to the present practice, the wood
or material is first formed into small blocks or slabs of the required length, suitable
to obtain the desired object. These blocks or slabs in most instances require to be
about twenty per cent. longer than the article to be produced, thus causing a con-
siderable waste of material, and when such blocks or slabs are cut to length, they
are put into one band to be bored, and then into another hand to be turned in the
machine and shaped, and if the articlo requires to be grooved or undercut inside, it
is passed to a third hand for this purpose.
The chief kinds of work which may be accomplished by my improved machine
are, the manufacture of stopper stems, especially stoppers for internally stoppering
bottles containing aerated waters, bobbins of any sort, rollers, pulleys, sockets,
buttons, rings, pill boxes, and other boxes, and various other descriptions of turnery
work, such as stoppers for lubricators, door handles and knobs, and other like
turnery work.

as herein described and shown in the Drawings hereto annexed.
Second. In machines for manufacturing articles such as internal stoppers for
bottles, simultaneously turning or shaping the outside, and boring, forming, and

In witness whereof, I, the said Léon Vallet, have have hereunto set my hand and
