Improvements in Apparatus for Manufacturing Screws, Bolts,
Nipples, Balls, Rollers, Studs, or like Articles from Rod,
Wire, or Tube, and for Drilling the same if Required.
I JOHN KEMP STARLEY of the Meteor Works, Coventry in the county of Warwick
Velocipede Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction of improved apparatus for manufacturing
screws, bolts rivets, nipples, balls, rollers, studs or like articles from rod, wire or tube
and by it I arrange a running head carrying turning tools and screwing dies or a
parting, milling or other tool in such a manner that any of the said tools or dies can
be brought on to or taken off the work without stopping the running of the head.
I arrange a hollow mandrel in which I mount a sliding sleeve or sleeves carrying
links pivotted thereto such links being connected to sliding pieces carrying the tools
and dies, the said slides working in grooves or guides, preferably dovetailed, which are
formed on the face plate carried by the running head.
By pulling back or pushing the sleeve or sleeves the tools or dies operate on the
rod, wire or tube and by reversing such action the tools or dies are taken off the
article to be formed. Suitable stops are employed and so adjusted as to ensure
the correct size being attained.
•
The number of links, slides and sleeves can be varied according to the number of
tools or dies to be used.
The sleeve or sleeves can be worked by a rocking lever or other suitable means and
grooved collars are attached to the sleeves into which the rocking levers or such like
attachments pass to allow the head to run freely. A suitable head or holder is
provided by which the said rod is firmly held in position to be operated upon by the
tools or dies.
When desired I may provide a drill in a suitable holder passing through and fitting
the innermost sleeve and arranged to be worked in the same manner, and so drill out
the article before it is moved or parted off.
For screwmaking the head or holder may be so arranged as to be worked by a
leading screw or when not required for this purpose may be made stationary.

page_text: The head or holder also can be made to slide to or from the running head
when desired and the feed could be arranged to be automatic by any well known
means.
Both heads fit in a bed provided to bring them true and to which they are both
secured.
It may be found necessary to use a tap or other tool in place of a drill.
When
I may arrange sliding jaws to hold the article to be bored or tapped and so that
when the said article is finished the said jaws are automatically released.
such holders are used the work can revolve and the tap drill or tool remain
stationary.
To make balls I arrange the several pairs of tools so as to variously operate on the
work; the first pair can be brought on to the rod so as to make a pair of grooves
of a suitable shape, the next pair or pairs rough out the ball and other tools size and
finish the ball and. by moving the rod forward the ball can be cut off and the rod
grooved for the next ball.
It will be easily understood that for some purposes it will be advantageous to reverse
the running of the head or holder.

1 JOHN KEMP STARLEY of the "Meteor" Works Coventry, in the county of Warwick,
Velocipede Manufacturer 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 relates to the construction of improved apparatus for manufacturing
screws, bolts, rivets nipples, balls, rollers, studs or like articles from rod, wire or tube
and by it I arrange a running head carrying turning tools and screwing dies or a
parting, milling or other tool in such a manner that any of the said tools or dies
can be brought on to or taken off the work without stopping the running of the
head.
I arrange a hollow mandrel in which I mount a sliding sleeve or sleeves carrying
links pivotted thoreto such links being connected to sliding pieces carrying the tools
and dies, the said slides working in grooves or guides, preferably dovetailed, which are
formed on the face plate carried by the running head. By pulling back or pushing
the sleeve or sleeves, the tools or dies operate on the rod, wire or tube and by reversing
such action the tools or dies are taken off the article to be formed. Suitable stops are
employed and so adjusted as to ensure the correct size being attained.
The number of links, slides and sleeves can be varied according to the number of
tools or dies to be used.
The sleeve or sleeves can be worked by a rocking lever or other suitable means and
grooved collars are attached to the sleeves into which the rocking levers or such
like attachments pass to allow the head to run freely. A suitable head or holder is
provided by which the said rod is firmly held in position to be operated upon by
the tools or dies.
When desired I may provide a drill in a suitable holder passing through and fitting
the innermost sleeve and arranged to be worked in the same manner and so drill out
the article before it is moved or parted off.
For screw-making the head or holder may be so arranged as to be worked by a
leading-screw or when not required for this purpose may be stationary. The head or
holder can also be made to slide to or from the running-head when desired and the
feed could be arranged to be automatic by any well known means.
Both heads fit in a bed provided to bring them true and to which they are both
secured.
It may be found necessary to use a tap or other tool in place of a drill and
may arrange sliding jaws to hold the article to be bored or tapped so that when
When such holders
the article is finished the said jaws are automatically released.
are used the work can revolve and the tap, drill or both, remain stationary.

page_text: To make balls I arrange the several pairs of tools so as to variously operate on the
work in different stages.
The first pair can be brought on to the rod so as to make a pair of grooves of a
suitable shape, the next pair or pairs rough out the ball and another set of tools can
size and finish the ball and by moving the rod forward the said ball can be cut off and
the rod grooved for the next ones.
(
It will be readily understood that for some purposes it will be advantageous to
reverse the running of the head or holder.
And in order that my invention may be understood and carried into practical effect
I have caused to be annexed to this specification the accompanying three sheets of
drawings and now refer to the Figures and letters of reference marked thereon.
On sheet 1 Figure 1 is an elevation of my apparatus, and Figure 2 a plan of the
same.
On sheet 2 Figure 3 is an enlarged vertical section of the means for operating the
sliding sleeves moving the tools as hereinafter described.
Figure 4 is an end view of the same.
Figure 5 is a plan view of Fig. 3.
On sheet 3 Figure 6 is an end elevation of the running head as arranged with 3 pairs
of tools working thereon.
Figure 7 is a section of the same on line 1-2.
a hollow
Figure 8 is a section through the line 3-4 of Fig. 6.
Referring to the said drawings A is a running head carried on
mandrel B which runs in bearings carried in standards C. D. on a bed plate E.
These bearings may be split as shewn in Figures 1 and 2 and adjusted by bolt and
nut as is well understood.
F is a speed pulley mounted on the mandrel B.
In reference to Figures 3 and 5 I have shown the details of my invention adapted to
operate two pairs of tools or dies; while Figures 6 and 8 shew the running head as
adapted for use with 3 pairs of tools or dies. I arrange sliding sleeves G, H, to work
in or on the mandrel B and carrying links I, J, pivotted thereto as at K, L. The
links are formed as bell cranks pivotted as at M, N, on bosses or lugs O on the face
plate P of the running head A. The short ends of the links or bell cranks engage in
slots or recesses Q in sliding pieces R working in grooves or guides S on the face
plate of the running head. As clearly shewn in Figure 8 these sliding pieces R are
shewn working in dovetailed grooves or guides, a setting up piece or strip T being
used to secure the sliding piece R in position and so prevent its leaving the groove
or guide in an outward direction. The tools or dies are secured to the sliding
pieces R.
Two methods are shewn in these Figures well known to mechanics, one having the
tool passing through a hole or slot in the sliding piece R and being secured by a set
screw, and the other plan having the tool clamped directly on the sliding piece by
bolts.
The sleeves G H run through the mandrel B and their ends carry grooved collars U V
one sleeve running on and projecting over the other.
On the bracket W I pivot yokes X Y at ZZ' such yokes carrying pins A¹ B' fitting
the grooved collars U. V.
The yokes X Y are connected to rocking levers C¹ and (pivotted to rods or
links Di D operating the same. E' E are adjustable stops (as shown headed screws
working in screwed bosses on the bed plate) to limit the downward play of the rocking
levers and consequently the travel of the sleeves G H in the hollow mandrel.
I have not shewn means for working the links D' D² to move the sleeves G H as
such will be readily_understood, as for instance treadles could be used.
In reference to Figures 6 and 8 three sleeves would be used and a corresponding
number of sliding clutches &c. But in Figures 3 and 5 only two sleeves (for two pairs
of tools or dies) are shewn.
By rocking the levers C¹ and C2 the pins A¹ B' on the yokes X Y can shift the
running grooved collars U, V too and fro and with them the sleeves G, H and thereby.

page_text: move the links I, J, pivotted thereto and to the sliding pieces R working on the face
plate of the running head and carrying the tools or dies whereby such can be taken on
or off the work without stopping the running of the machine.
A suitable head or holder E³ secures the rod wire or tube to be operated upon
firmly in position while the tools or dies work on the same.
As shewn in Figs. 1 and 2 I may use a head or holder and secure the rod wire or
tube by a set screw F¹ and I can use a boss G¹ on the head or holder through which
slides a pin H' secured by a set screw I. This pin H carries an upright piece J'
connected to a boss K' through which the rod wire or tube to be operated on slides,
and to which boss K¹ it is clamped by a set screw L'.
The head or holder can be pushed up to the running head by hand in which case I
may arrange a pivotted pawl or catch adapted to lock into recesses on the machine bed
and so keep the head or holder in position, or I may traverse the head or holder
towards the running head carrying the tools by a leading screw or otherwise.
I have not shewn a plan for automatically feeding the rod wire or tube to the running
head as many devices suitable for the purpose now in use to feed forward a rod wire
or tube could be used.
:
In Figs. 1 and 2 I have shewn a means of fitting a drill or tap to my apparatus
whereby I can drill or tap an article while held in the running head and before finishing.
and parting it off.
N and N are brackets in which runs a mandrel P¹. O₁ is a speed pulley thereon;
Qis a clutch or holder R' is a drill running through the innermost sleeve (H) in the
hollow mandrel B and going up to the work held in the running head. S¹ is a grooved
collar in the mandrel P₁. Ta pivoted yoke engaging therewith, and U¹ a rocking
lever pivoted to said yoke. V¹ is a link or strap to move the lever U₁ and so pull the
mandrel P and with it the drill R' from the work in the running head or push the
drill forward to operate on the work.
The drill mandrel can be driven off a counter-shaft (not shown).
If desired I can run such articles as headed screws to be cut back into the running
head, and by forming the innermost sleeve (H) with spiral blades or other carrying
surfaces I might feed the machined articles backwards and out of the machine into a
hopper or receptacle.
The tools shown in the drawings are merely examples of mounting various tools on
my machine.
For ball making I may require more than three pairs of tools in which case I must
use more than three sleeves and means for operating the same.
If desired I might move the tools from the face or in front of the running head, but
I prefer the plan shewn. And 1 could by providing a suitable countershaft arrange
for ready reversal of the running head.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
First In apparatus for manufacturing screws, bolts, nipples, balls, rollers, studs
or like articles from rod wire or tube arranging a running head carrying tools or dies
working in grooves or guides thereon and operating so that the said tools or dies may
be taken on or off the work held in a suitable fixed head or holder without stopping
the running head substantially as described.
Second-In apparatus for manufacturing screws, bolts, nipples, balls, rollers studs
or like articles the combination of a running head, sliding tool or die-holders mounted

rotating mandrel carrying the running head, and with means for operating the sliding
and rotating sleeves, whereby the tools can be taken on or off the work held by a
suitable fixed head or holder without stopping the running head substantially as
described.

page_text: Third-In combination with apparatus substantially as hereinbefore described, of
a sliding and rotating mandrel carrying drills or taps adapted to pass within or through
the hollow rotating mandrel carrying the running head and its tools, whereby I can
(if required) drill or tap the work operated on by such running head before finishing
or parting off the same substantially as described.
Fourth-The general arrangement construction and combination of apparatus for
manufacturing screws, bolts, nipples, balls, rollers, studs or like articles from rod wire
or tube and for drilling or tapping the same if required substantially as hereinbefore
described and illustrated in the accompanying drawings.
