WILLIAM Ross of Holmside Muswell Hill in the County of Middlesex Engineer
and JOHN BILBIE of Fairleigh Bowes Road Palmers Green in the said County of
Middlesex Engineer, do hereby declare the nature of this invention to be as
follows
--
To improve certain portions of a Machine described in Specification No. 4131
March 18th 1887 for Improvements in Boot and Shoe Machinery."
Firstly. Whereas in the before named specification we describe a roller or cylinder
and segments outside such roller or cylinder we deem it advisable under certain
circumstances to place the segments inside such cylinder-and to thread the inside of
the cylinder and the outside of the segments or either of them only. The segments
being made to revolve only or the exterior cylinder only or in some cases both
cylinder and segments may revolve at the same time or alternately. The cutters may
be placed either in the cylinders above described or in the segments. In some cases
we build up both cylinder and segments or either of them of rings or segments of
rings or sections between the cutters so that we can place any thickness of ring or
segment of ring (threaded as described in former Specification above referred to or
left plain) between the cutters and thus vary the length of the stud produced to suit
the thickness of material at will. We also in this case have the cuttings formed in
rings or segments and the cutting edge shaped so as to perform the operation of
cutting the wire during the process of threading and these.may be varied to suit any
thickness of wire required. The wire having been cut and threaded as described
above we draw it into a recess by suitable means and it is conveyed into tubes
through the bed plate of this portion of the machine, which bed plate is pierced with
a series of holes accurately placed so as to receive such formed studs and such bed
plate having fed one hole moves to the next hole either by means of a ratchet or
other suitable appliance and so on successively so as to enable the cutters to supply
the series of tubes attached to the above named series of holes and by regulating the
gearing of the ratchet and the gearing of the rotating parts, the whole of the series

page_text: of holes or any desired portion of them with their respective tubes will be constantly
supplied regularly with perfect studs as required.
We find it convenient sometimes to place our dies and fillers referred to in our
former Specification before referred to in a circle or other suitable position having
any other number of dies and the corresponding number of fillers and move them
either always one way from filler to studding die thence to the next filler and on to
the next studding die or from filler to die and back again and so on continually. We
can thus arrange for one machine to stud the material any number of patterns or
designs.

In the specification above referred to, we describe an apparatus for cutting lengths
of wire into studs, consisting of a cylinder to be rotated within a hollow cylinder
built up of segments.
According to our present invention, we place the segments inside the cylinder, and
form the cutters upon the periphery of the inner cylinder. This modification is
illustrated in Figs. 1 and 2.
A, A are the segments, together forming the inner cylinder fast upon the shaft, B;
and having the cutters, e, projecting from its periphery. C, C are the filling spaces.
The inner cylinder is rotated in the direction indicated by the arrow, by any suitable
gearing, e.g., that illustrated in Fig. 1; and the outer cylinder, D, in the opposite
direction by the ratchet gear, E, operated by the stud, e, engaging in a slot in the
vertical connecting bar, F.
We do not confine ourselves to rotating both cylinders, as one only may be made
to rotate if desired, and the cutters, c, may be fixed either upon the outer or the inner
cylinder.
The cylinders are illustrated in Fig. 1 as solid; but we may, according to our
present invention, build up either or both of sections, or strata, united in the
horizontal plane by any convenient device. The advantage of this method of
constructing the cylinders is this, that a machine can be altered to produce studs
longer or shorter, by taking the cylinder on which the cutters are fixed to pieces, and
changing the sections for others, thicker or thinner as may be required.
The cutters, c, are shewn in Fig. 1 as fixed to the cylinder, i.e., non-adjustable ;
but, according to our present invention, we may make them adjustable in respect of
their projection from the periphery of the cylinder carrying them, for the purpose of

page_text: adapting the machine to cut wires of various thicknesses, without it being necessary
to change cylinders. We do not confine ourselves to any particular device for
effecting the above described adjustability of the cutters, but may employ any that
may be suitable.
The cutters illustrated in Figs. 1 and 2 are separate blades inserted in the cylinder;
but we may, according to our present invention, make them solid i.c., in one piece
with a ring adapted to be keyed, or otherwise rigidly attached, to the cylinder.
G is a bed plate rotated by the ratchet-gear, E, under the cylinders, and in the
same direction as the outer cylinder D. Perforations, g, are formed in it, which
respectively communicate with tubes, H; delivering into a hopper, i. As the
perforations, g, come under the discharging ports, h, in the inner cylinder, the studs
drop therefrom into the hopper from which they fall into the fillers, J, as described in
said previous specification.
The devices for piercing the leathers and inserting the studs illustrated in Fig. 1
are identical with those illustrated and described in our said former specification';
and, therefore, form no part of our present invention. But instead of the rotary
motion and gear to effect the same described in our said specification, we may use a
gear, K, worked from the stud, e; by means of which-a reciprocating motion may be
imparted to this part of the machine.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we'
claim is:.
1. The combination of inner cylinder, built up of segments, with an outer
cylinder, either or both adapted to be rotated about a common axis, substantially as
described.
2. Constructing the cylinder of a stud-making machine of sections. or sirata,
whereby it is adapted to be adjusted in respect of the length of stud it will make
substantially as described.
3. The combination of cylinder and cutters adjustable in respect of their projection:
from the periphery of said cylinder substantially as described.
4. The combination of connecting bar, ratchet-gear, and gear K, adapted to
rotate the outer cylinder with an intermittent circular motion and the studding
device with a reciprocating motion, substantially as described.
