I, WILLIAM HENRY GREATOREX of Wycliffe Road Lavender Hill Battersea in
the County of Surrey, Brassfinisher 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 :-
My invention relates to an apparatus whereby an ordinary lathe may be used;
for, milling, slot drilling, drilling, and boreing purposes.
To carry out my invention, I fix a slide to the bed of a lathe, parallel with the
length of the lathe bed the said slide being held in position by means of a bow nut
and washer.
For the purpose of actuating the above mentioned slide, a vertical bracket is
fitted to the bed plate of the slide on the end which is farthest from the headstock
of the lathe, the vertical surface being parallel with a line across the bed of the
slide and at right angles with its length.
This bracket supports a cylinder fitted up with a poppet head arrangement, the
said cylinder laying horizontally parallel with the length of the slide, and, at right
angles with the bracket by which it is supported.
I also secure a vertical bracket to the top plate of the slide, hereinbefore inen-
tioned, having its surface parallel with the surface of the bracket on the bed plate,
and by securing the end of the plunger of the poppet head to the above named
bracket, I obtain the feed or horizontal traverse to the apparatus, the screw in the
poppet head actuating the plunger by means of a wheel or handle.
For the purpose of milling work of the character done in an ordinary Brass
finishing milling machine, and in certain forms of drilling, the tool in these and all
circumstances being fixed in the head-stock of the lathe I have a flanged socket,
bored to recieve suitable chucks; the said socket revolves in a table, the surface of
which table, lays horizontally parallel with the bed of the slide hereinbefore men-
tioned; the flange of the above named revolving socket, is set out on its periphery
with one or several series of division holes, the said division holes being governed
by an adjustable spring catch that can be raised or lowered to engage with either
series of holes.
The table carrying the revolving socket herein before mentioned, is attached to
the horizontal slide of the apparatus by the following means.
Four vertical pillars slide in sockets cast in the table above mentioned, Two of
the said pillars are screwed into a horizontal bar, which bar travels in a channel
bored across the top plate of the horizontal slide herein before mentioned, at that
end of the plate which is nearest the head stock of the lathe, the above named
channel is slotted through its length to enable the two vertical pillars to be carried
with the horizontal bar to which they are attached, in its lateral traverse, in the
above nained channel.
To adjust the level of the table containing the revolving socket, also to relieve
the weight thereof, oue of the above named vertical pillars is screwed and has a

page_text: running nut, on the under side of the table; the other pillar is temporarily fixed
to the table, by a binding screw taped in the socket of the table through which it slides.
The two remaining pillars form the uprights of a vertical slide, the horizontal
base, into which they are screwed, being a V strip, that slides in a V groove cut to
recieve it, in the top plate of the horizontal slide herein before mentioned, the said
groove being at the end of the bed plate of the slide, farthest from the head stock
of the lathe, and horizontally parallel with the channel, in the opposite end of the
plate herein before inentioned.
These last named pillars slide in two sockets in the table, and, are attached to a'
top strip that lays horizontally parallel with the V strip at the base.
For the purpose of giving the table containing the revolving socket, hereinbefore
mentioned, a vertical traverse on the above named slide, a screw passes from the
top to the bottom of the slide-engaging with a hole taped in the table, actuating
the table containing the revolving socket, in its vertical traverse on the slide, by
means of a handle attached to the top of the screw.
To give rigidity to the above named vertical slide, the bracket on the top plate
of the horizontal slide hereinbefore mentioned, is carried up to support a barrel,
on a horizontal plane, with the top strip of the above named vertical slide; the
barrel is slotted on the side abutting the above named top strip of the slide, so that
a bar traversing the bore of the barrel can be tied to the vertical slide and travel
with it in a lateral direction.
For the purpose of obtaining the necessary lateral traverse to the apparatus a
screw runs in two bearings cast to the top plate of the horizontal slide hereinbefore
mentioned, so that it shall be horizontally parallel with the ✓ groove already
described; the said screw engages with a lug projecting from the V strip of the
vertical slide, which it actuates in a lateral direction, by means of a handle attached
for the purpose.
A guide rod also runs on the opposite side of the V groove to that of the screw;
the said rod being held in bearings bored through the joint of the bracket with the
top plate of the horizontal slide, the above named guide rod being utilized as a bolt
to clamp the bracket to the top plate of the slide, by means of jamb nuts; a lug
projecting from the V strip of the vertical slide is bored to recieve the said guide
rod over which it slides, so steadying the vertical frame in its position in the
V groove and preventing any strain on the screw.
•
For the purpose of boreing, slott drilling, drilling and milling in the length
I make use of the following combination chuck.
I have an oblong table with a vertical shank the said shank fits the bore of the
revolving socket herein before mentioned; the oblong table stands lengthways across
the horizontal slide, with its surface parallel with the bed of the slide.
Two vertical brackets traverse the oblong table above named, actuated by screws;
the vertical surfaces of the brackets stand parallel with each other, across the width
of the table.
To utilize these brackets as a vice chuck in conjunction with the oblong table
which they traverse,
I clothe the plinth of each bracket with a roughened steel strip, so that when the
work is placed on the table, and the brackets actuated by the screws, by means of
a loose wrench, the work is securely gripped between the steel jaws, and can be
operated upon for boreing, milling, or drilling; a tool suitable for the purpose being
fixed in the headstock of the lathe.
The brackets above mentioned have also one or more sets of V gaps, cut out of
their thickness, each pair of V gaps having their surfaces on a plane with each
other, that is to say, if a parallel rod is placed in a pair of V gaps above named it
will be parallel with a centre line through the length of the oblong table traversed
by the brackets, each of the above named V gaps has a bracket cast or fitted to
bridge it over so that a vertical screw can be brought to bear on the work-to
secure it temporarily in its position; this arrangement is intended to hold an object
in length for slott drilling, drilling, milling, or key way cutting, and operations of

page_text: a kindred character; the work can be tapered by setting the chuck at an angle
with the tool in the headstock of the lathe.
For such purposes as milling, the flutes in taps, or the flats of reamers, the
grooves in rose cutters, and operations of a kindred character, also in some circum-
stances of drilling,
I have a centre in each of the above mentioned brackets, opposite to each other,
so that, when a parallel rod is placed between them, it will lay horizontally
parallel with a centre line through the length of the oblong table; one of the
above centres advances and recedes to allow the removal of the work without
shifting the bracket.
The centre in the other bracket, has a collar to shoulder it on the inside of the
bracket, and is fitted with clamps and screws to temporarily fix the object to be
operated upon, to the said centre; on the tail end of this centre projecting through
the outside of the bracket, a disc is keyed, with its surface vertically parallel with
the bracket to which it is attached, the surface of the above named disc is set out
with one or several series of division holes, that are governed by a spring catch,
and as the centre and the object clamped thereto revolve in the same axis as the
disc, the object held between the centres is offered to the tool in the head stock
of the lathe to cut the desired number of grooves, flutes, flats or holes, by
engaging the spring catch with the requisite series of division holes, in the disc
above described.
To taper the work, the chuck is set to an angle to the tool in the headstock of
the lathe.
To enable my invention to be clearly understood, I will proceed to describe the
same, with reference to the accompanying drawings, in which,
Fig. 1. is a plan of the apparatus without the combination chuck.
Fig. 2. is a front elevation of the apparatus, shewing the combination chuck in
its position.
Fig. 3. is an end view of the apparatus without the combination chuck.
Fig. 4. is a plan of the combination chuck.
Similar letters refer to similar parts in figures 1. 2. 3 and 4.
A. A¹ is a horizontal slide, shewing ribs at G. that can be planed to suit the form
of the bed of a lathe.
B. B¹ are vertical brackets connected by the travelling ram R. of the poppet
head C; the screw of the poppet head actuates the slide by means of the hand
wheel O, giving the necessary horizontal traverse to the apparatus.
The bolt for temporarily fastening the apparatus to the bed of a lathe, by
engaging with a bow nut and washer, screws into the hole taped in the rib at P'.
E is a flanged socket revolving in a table F. held thereto by a screwed washer P;
the chucks to hold the object to be operated upon, are fitted to the bore of the
revolving socket at R, and temporarily fastened by the screw S; the division
holes W in the revolving socket E are governed by the adjustable spring box H, so
that an object chucked in the revolving socket, can be offered to the tool in the
headstock of the lathe, to be milled, or drilled with a given number of sides or holes,
by engaging the spindle of the spring catch with the series of holes that will give
the proper multiple, to produce the figure desired. S is a screw to temporarily
fasten the socket E to the table F while the cut is being taken.
The vertical slide formed by the pillars J. J and the cross pieces U. V. upon
which the table F carrying the revolving socket E travels, and can be raised, lowered
and adjusted as required, for which purpose the screw T, by engaging in the hole
taped in the table at X by means of the handle X attached to the screw, actuates
the table on the vertical slide; thus the object chucked in the socket E can be
adjusted to the height of the tool in the headstock of the lathe.
The vertical slide J. J' U. V. upon which the table carrying the revolving socket
travels, is attached to the horizontal slide A in the following manner;
The V strip U, slides laterally in the V groove U, and the top strip V is bolted
to the tie rod I traverseing the channel L' of the bracket B in a lateral course.

page_text: o is a slot in the barrell, to pass the bolts that tie the strip V, to the rod I¹, so
allowing the rod I¹ to travel within the vertical slide, and table F, and support it
in its vertical position.
L is also a channel in which the bar I travels laterally; the channel is slotted
at o. to allow the vertical pillars J. J. to screw into the bar, I and travel with it in
its course; the table F slides on the pillars J. J. one of which is screwed and has
a running nut K to adjust the level of the table F, and relieve its weight; the
other pillar is temporarily fastened to the table F, when the level is adjusted by
the screw S¹
The necessary lateral traverse is given to the apparatus as follows,
A lug Y projects out from the V strip. U of the vertical slide, and is taped to
engage with the screw T¹, the screw being held in position by the two bearings N. N.
cast to the horizontal slide A¹, the strain on the screw being prevented by the guide
rod I upon which the lug Y', projecting from the V strip U of the vertical slide
runs; the rod I" is also utilized to fasten the bracket B to the slide A' by passing
through the joint of the bracket with the slide at A" and screwing on the jamb nuts
as shewn.
Thus the screw T¹ by means of the handle B actuates the apparatus in a lateral
direction.
When therefore the object to be operated upon is chucked in the revolving
socket E, it is under the control of the division holes W, and the lateral, vertical,
and horizontal traverse, as shewn above.
Fig. 2. represents the combination chuck in its position, in the socket R of the
apparatus.
Fig. 4. represents a plan of the combination chuck.
The shank A fits the bore R of the socket E, and is temporarily fixed by the
screw S. and is thus brought under the control of the apparatus, so that, the object
held in the chuck, can be adjusted, fed, and traversed to the tool in the headstock
of the lathe.
The brackets c. c¹ traverse the table b, actuated by the screws, d. by means of
a loose wrench; L. L are steel strips roughened to form a vice to grip between them
an object, requireing to be either bored, milled, or drilled, by a suitable tool in the
headstock of the lathe.
The V gaps. g. are for the purpose of laying an object in the length, as a rod,
that may require to be slotted, milled, or; drilled; the screws. m. in the brackets m¹
are for temporarily holding the object in the V gaps, while the operation is
performed.
t. are two centres, one of which advances and recedes, in the bracket c.
The other centre t¹ is shouldered into the bracket c¹, and fitted with clamps and
screws h. to temporarily fasten the object to be operated upon, to the centre.
j. is a disc, keyed to the tail end of the centre t'; n. are division holes in series
governed by the spring catch k. so that, the object held between the centres t. t'
and clamped to the centre t¹, is brought under the control of the division holes, n.
and is offered to the tool in the headstock of the lathe, to produce the number of
flutes, slots, sides, or holes; the nature of the operation may demand, by engaging
the spring catch k. with the series of holes in the disc j. whose multiple will give
the object between the centres the required number of turns.
To use the vice as referred to above, it may be well to say the centres if needful,
are easily withdrawn from the brackets.
To taper the work, the table 6 must be set at an angle to the tool, in the
headstock of the lathe.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. The apparatus as described, consisting of the table, containing the revolving
socket, and adjustable spring catch, also the combination, and arrangements of parts,
