the flanges of sections of boiler flues in an expeditious manner, but which tool or
machine may also be used for drilling and turning for other purposes
My Invention consists in a combination and arrangement of mechanism, namely,
a bed somewhat similar to a lathe bed with a fast headstock for carrying a hori-
zontal spindle on which there is a face plate having three or more jaws which can
be simultaneously expanded or contracted by screws or other means to take hold of
the article to be operated upon I prefer to drive the spindle of the headstock by a
worm and worm wheel, though other gearing may be used, and to drive the worm
shaft from a horizontal driving shaft parallel to the lengthway of the bed

ordinary lathe, but this headstock carries a spindle with face plate similar to that of
the fast headstock, but the spindle of this headstock (which is moveable upon the
bed to adjust its position by a rack and pinion or other means) is rotated by con-
nection with the article held between its face plate and that of the fast
headstock

HENRY GEORGE JORDAN, of the City of Manchester, in the County of Lancaster,
Engmeer "IMPROVEMENTS IN TOOLS OR MACHINERY FOR DRILLING and TurnING
CYLINDERS FOR BOILER FLUES AND ARTICLES FOR OTHER PURPOSES"
The principle object of my Invention is a tool or machine for drilling and turning
the flanges of sections of boiler flues in an expeditious manner, but which tool or
maclune may also be used for dilling and tuning for other purposes
My Invention consists in a combination and arrangement of mechanısı, namely,
a bed somewhat similar to a lathe bed with a fast headstock for canying a hou-
zontal spindle on which there is a face plate, by preference having three or more
Jaws which can be simultaneously expanded or contracted by screws or other moans
to take hold of the article to be operated upon I prefer to drive the spindle of the
headstock by a worm and worn wheel, though other geaning may be used, and to
dive the worm shaft from separate driving pulleys or from a horizontal driving
shaft parallel to the lengthway of the bed
The gearing for rotating the headstock spindle continuously is arranged so as to
be disconnected, and so that other gearing can be brought into gear for dividing
purposes, that is, for 1otating the spindle a fraction of a tuin of the spindle at a
time for dulling a ficsh hole or set of holes There is another headstock somewhat
sunilai to the following headstock of an ordinary lathe, but this headstock carries a
spindle with a face plate sunlu to that of the fast headstock, but the spindle of

page_text: this headstock (which is moveable on the bed to adjust its position and may be
adjusted by a sciow or 1ack and pinion or other means) is rotated by connection
with the article held between its face plate and that of the fast headstock The
article may be placed on a mandril and held between centres on the fast and looso
headstocks if desired
Upon the bed there are two slide saddles which can slide along it, and may bo
slided by a sciow 01 1ack and pinion or other means, and upon each slide saddle
there are one or two cross slides which slide upon the saddles at a night angle to
the lengthway of the bed, and each cross slide cannes an upright pillai which has
one or two slides upon it, each slide canying a horizontal drill spindle parallel to
the headstock spindles
The two slide saddles on the lathe bed are actuated by screws which can be
geared together, so that they can be simultaneously or separately moved either way
for adjustment, and to feed and withdraw the one or two drills carried by each of
the two or four pillars
The two slides catiying the pillais on each slide saddle are or may be connected
by a night and left handed sciew to adjust them to and from cach other simul-
taneously or separately
The two slides carrying each a drill on each pillai are or may be also connected
by a night and left handed screw for simultaneous or sepuiate adjustment each way,
and the sciews for the drill slides and for connecting the slides for the pillars
are geared together so that simultaneous or separate movements of the dull and
pillai slides may be obtained, and if desired the screws for the slides carried on one
slide saddle ale or may be geared with those of the other saddle by a horizontal
shaft with wheels sliding on keys on the shaft
Clam" nuts or other airange-
ments may be used so as to connect and disconnect the slides from the screws so as
to give or allow of separate adjustment to cach when desired There is a horizontal
Cross shaft or shafts having bearings in each slide saddle which gears with a wheel
sliding on a key on the houzontal diving shaft, and those cross shafts gear with
upiight shafts in the pillais for diving the drills
"
The sciew or sciews for giving motion to the saddles is or are geared with the
driving shaft when dilling for giving the feed or for withdrawing the drills which
Is accomplished by reversing the rotation of the dills or by clutch and reversing
geal acting on the saddles
Other sciews or racks and gearing may be used in place of the right and left
handed screws if desned With this tool with two pillars on each saddle, four
dills can operate upon each flange of the section of a boiler flue, thus diilling eight
holes simultaneously, but one, two, or more of the drills may be used as desued,
either simultaneously or separately
For tuining; one, two, of more tooliests are placed upon the slide saddles carrying
the pillars or upon arms or brackets from the headstocks
Dill spindles may be placed on the slides above referred to, to drill at a night or
other angle to those described if desired
Fig. 1 is a longitudinal elevation, Fig 2, a plan, and Fig 3, an end view
illustrating the mode of carrying out my Invention
a is the bed which has slideways upon it for the cross saddles, and facings for the
fast headstock, and slideways for the loose headstock, b is the fast headstock,
it is made with two feet to bolt on to the bed to form a bridge over the saddle
which passes across the bed under the headstock, the length of the span of the
bridge of the headstock being made sufficient to allow of the requued longitudinal
movement of the cross saddle upon the bed. The headstock (b) canes a tubular
spindle, upon the inner end of which a face plate b¹ is secured in which there are
three or more radiating grooves each having a screw (62) in it which screws through
a slide or bracket 6 which is thus drawn inwards or pushed outwards The
Screws (62) in the face plate 61 at theu inner ends gear with a wheel upon the end
of a shaft 6 in the hollow of the lathe spindle, the end of this shaft coming to the
outer or back end of the lathe spindle where it has a "square" upon it for a crank

page_text: handle, by which the jaws or slide brackets aic adjusted and made to hold the
article placed upon them
,
The face plate b is made small enough in diameter to allow of holes being drilled
at the nearest distance required from the axis of the spindle for the smallest sections
to be diilled, and the jaws 68 will expand to take in the largest sections intended
to be dulled, or binckets can be bolted to them for larger diameters if desired
Upon the back end of the central shaft b' there are two loose driving pulleys c
one of them has a pinion c¹ on its boss that gears with a caller wheel on a stud in
the headstock, the carrier gearing with a wheel on the end of a shaft c² in bearings
in the headstock, which shaft (c²) by bevel wheels gears with a shaft in bearings
in the headstock at right angles to the lathe spindle, which shaft (c³) has a wom
upon it that gears with a worm wheel 6 on the lathe spindle, thus arranged, the
lathe spindle is driven by a belt working on the pulley c, but when the belt is on
the adjoining loose pulley the lathe spindle and face plate may be rotated for
dividing or other purposes by a crank handle c* (see Fig 1) on a boss on a stud
secured in an adjustable bracket co attached to a bracket c' secured to the part 6º
from the headstock, which boss has a wheel upon it that gears with one on the
end of the worm shaft (c) By making these wheels "change wheels," any required
division for the holes to be drilled may be obtained The boss for the handle has
a disc secured upon it with a notch in it for the bent end of a lever c³ on a stud
in the bracket co, which bent ended level is to hold the handle from turning after
each adjustment, and the lever c³ has to be depressed to withdraw its bent end from
the notch in the disc before the crank handle c can be turned The bent end of
the lever is pressed upon by a spring to force it into the notch in the disc when it
comes round
The loose headstock b* has a spindle and faco plato 6' with Jaws b³
and screws and a central shaft b for actuating the jaws same as the fast head-
stock b, and this loose headstock also spans over the cross saddle same as the fast
headstock, but the loose headstock 6* is fitted in slides so that it can be adjusted
and secured on the bed (a) when adjusted by "-headed bolts in slots in the bed
For tuining there is a bracket 6º cast upon or fixed to each headstock, which
bracket canes ordinary compound slides b for holding the turning tool
The cross saddles & and the slides and pillais e and the slides and dull spindles
canned upon pillais e are all alike, so that it will only be necessary to describe
the parts in connection with one pillai (e) and the manner in which the pillars alo
connected together and the diills are rotated d, the cross saddles on the bed a,
e, pillars with slides formed at their lower ends to slide on the saddles The pillars e
have vertical slideways for slides f, each carrying a hearing for a drill spindle f¹ that
is diven by a bevel on a short vertical shaft having bearings in the drill spindle
slide f, which short shaft at its lower end has a spui wheel upon it that gears with
one on a vertical shaft f' having its bearings in the pillai e, this latter wheel has
bearings in the dull spindle slide f so as to move with it and slide upon the
vertical shaft f³, being connected therewith by a key and key groove The lower
end of the vertical shaft has a bevel wheel that gears with one having bearings
in the pillai slide e which slides upon a horizontal shaft d, being connected to it
by a key and key groove, which shaft d has bearings in the saddle d and on its 4
inner end it has a bevel which gears with a bevel having bearing in the saddle,
which bevel wheel slides upon and is 10tated by a key and key groove in a shaft a¹
in bearings the lengthway of the bed u
At the fast headstock end the last-named shaft a¹ has fast and loose pulleys of
two sizes a and a' for an open and cross belt, one belt giving the slow speed for 5
dilling and feeding the diills, and the other or cross belt a quick reverse rotation
for withdrawing the dulls The diving belts are traversed by belt guides a* and a³
on a slide 1od um suitable bearings, which slide 10d is actuated by a lever handle a
having its fulcium on the fast headstock and connecting 10d as between it and the
slide iod at The two pillars e on each saddle d are moved by a light and lett 5
handed screw d², having bearings in the saddle d, which sciew screws through nuts
in the pillar slides, and the screw is 1otated by a crank handle placed upon a'

page_text: "square" on the end of the right and left handed scrow The pillars are adjusted
separately by making the nut in a tangent wheel or worm wheel, and making this
tangent or worm wheel gear with a tangent wheel or worm on a cross shaft e¹ in
bearings in the pillar e, this shaft et being 1otated by a hand wheel es The drill
spindle slides f on each pillai (e) are actuated simultaneously by a right and left
handed screw c³, which sciew sciews through a nut formed in a tangent or worn
wheel in bearings in the dull spindle slide f, which tangent or worm wheel also
geas with a tangent or woim wheel on a horizontal cross shaft e' in bearings in the
dill spindle slide f, having a hand wheel e', so that by turning the short shaft et
cach slido can be separately adjusted, and by turning the night and left handed
screw by a crank handle fitting the square at the upper end of the pillar e both
drill spindle slides fare simultaneously adjusted
The two saddles & are moved to and fio for adjustment or for feeding and with-
drawing the dulls by two screw shafts g and g' having bearings in the bed a These
screw shafts screw though nuts in the saddles < At the loose headstock end of
the diving shaft a¹ there is a bevel wheel which genis with one on a short vertical
shaft a, having bearings in a bracket from the bed, and upon the lower end of the
short shaft a there is a worm that gears with a worm wheel g² loose on the end of
the screw shaft g, but on the boss of the worm wheel there are clutch teeth which
can gear with corresponding teeth on a clutch sliding on a key on the end of the
screw shaft g, which clutch can put in and out of gear by a clutch folk lever g³,
jointed on a bracket from the bed (a) The two screw shafts g and g² are geared
together by spur wheels g', so that when the clutch actuated by the fork (g) is in
gear both cross saddles d and the pillais e carried by them are sunultaneously
moved to and fio one way when dilling, and the reverse way when the diving
shaft als 10veised When the clutch (g) is thrown out of gear the saddles, d can
be adjusted by a crank handle on a "square" at the end of the screw shaft g, and
when a separate adjustment of each saddle 18 required it is done by sliding one of
the wheels g' on the shaft g on a key out of gear with the other on the shaft g¹,
and then tuining these screw shafts by a handle as lequued
If desired there may be only one dill caused by each pillar e, the dull spindle
being carried directly by the pillar, and coming on a bevel with the axis of the
lathe spindle
If desired only one saddle d may be used carrying one or two pillars (e), with
one or two dull spindles on each pillar The drills may be diven always in one
duection, and a double clutch and reversing gear or other arrangement may be used
to feed and withdraw the drills
There may be a separate feed motion to cach dill, the pillars being stationary
when dilling, and the feed motions of the drills may act separately, or may be
geared together to act simultaneously if desned
I have now particularly described the nature of my Invention and the manner of
carrying the same into effect, and claim as my Invention,-
Firstly The combination and arrangement of two headstocks to hold and rotate
