Improvements in Turret Lathes.
I, JAMES HARTNESS, of Springfield, in the County of Windsor, State of Ver-
mont, United States of America, Gentleman, 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 has relation to tunet-lathes, or screw-machines, and has for
its object to provide a machine of the class-mentioned, capable of performing
chucking and tuning operations, and equipped with hand and automatic devices
for causing the tools to operate upon the stock in proper succession and to the
proper extent whereby a piece of raw material may be properly turned, and
delivered as a finished article.
The invention has likewise for its object to provide a machine of this character
which will automatically regulate the speed of 1otation of the work, whereby it
may be driven at a predetermined rate of speed, and may be duven at diffeient
speeds, and also to equip the machine with mechanism for automatically advanc-
ing and withdrawing the tunet rapidly toward and from the stock on work, and
feeding it slowly while the tool is performing its allotted duty
Still another object of the invention is to provide other improvements in turret-
lathes, whereby there may be obtained a greater control over the work and tools,
the work may be held igidly against strains, a greater number of operating tools
may be attached to the turret than heretofore, the tuiet may be locked with
greater rigidity in desired locations and properly indexed, and the machine itself
rendered more accurate, durable and efficient in operation than heretofore.
A further and important object of the invention is to provide controlling
mechanisms for the various movable and operative parts of the machine, whereby
they may be governed or controlled with a very slight effort on the part of the
operator.
To these ends the invention consists of the machine and improvements which
are fully illustrated upon the drawings, and shall now be described in detail,
and finally pointed out with particularity in the claims hereunto appended
Reference is to be had to the accompanying drawings and to the letters of
reference maiked thereon, the same letters of reference indicating the same parts

Referring to the drawings, which show one embodiment of the invention which
I have selected for the purposes of illustration and disclosure a indicates the
bed of the lathe which is mounted upon suitable legs or supports, and is pro-
vided with ways or shears b, b, upon which the carriage d travels lengthwise
thereof
The rotating plate-shaped turret c 18 mounted upon the carnage d and 18
arranged to receive a series of cutters or other operating tools which are adapted
to be brought successively into position to act upon the stock or material held
in the chuck
The bed of the lathe is hollow and has a peculiar shape, having a flat top or

page_text: table-like portion a¹, upon which the ways are supported and the under portion a³
which slants downwardly from the forward end towards the rear, as shown in
Figures 1 and 55, the bed as a whole being substantially wedge-shaped. At its
head end, it is provided with the head-stock or bearing ing a³ which 11ses fiom
the horizontal portion a¹ and laterally from which are extended two wings a', at
as best shown in Figs. 50, 51 and 55. In side elevation, the said wings are
irregular in form, but approach the shape of an oval, being extended longitu-
dinally of the machine to form a housing for the chuck and the chuck-cailler,
which may be either a spindle, or the devices hereinafter described
Besides covering and protecting some of the moving parts of the lathe, as well
as the ways beyond which it projects. the housing forms a firm support for the
head-stock a³.
A
The said bearing ring or head-stock is provided with an internal flange or
gib a³ and secured in the said ring forward of the flange is a stationary plate a
having a cential rearwardly projecting annular hollow flange or hub a.
Cucula plate or chuck-caie a is jou nalled upon the hub a', with its face
flush with the outer surface of the flange or gib a³, being formed with a flange a
having gear-teeth and overlapping the said flange or gib as Rolls a, a,
placed in separator-rings a, a, are inserted between the flanges a³ and the
gab on the one side, and the plate a on the other side, whereby when the
chuck-carrier or geal a 18 rotated it is held against endwise movement and
angular strains The chuck indicated as a whole at a¹³ is rigidly secured to the
said camer In order to compensate for wear, a fiusto-conical bushing 18
inserted between the hub of the bearing-plate a and the forwardly projecting
hub of the chuck-cariei, said bushing being adjusted by screws passed through
the plate and bearing against its end.
It is
The chuck-cane being in the form of a plate with a bearing at or near its
center and end-thrust bearings at or near its im 18 held against eccentric and
endwise movement and is abundantly able to withstand angular strains
adapted to receive such work and stock as pulleys, cylinder-heads, etc, and 18
provided with the central aperture for receiving back facing tools having special
attachments to operate, for instance, on the inner end of a pulley-hub It will
be noted that I employ cylindrical rolls, and confine them in separator or retain-
ing ings, whereby I am enabled to prevent then wedging between the rotary and
the stationaiv parts
The chuck-caiier may, so far as certain other features of the invention (hele-
after descubed) are concerned, be in the form of a spindle, and be mounted in
any suitable beaiings in the head-stock, but as illustrated and described herein,
its peripheral teeth inter mesh with a pinion a" on the end of a shaft whereby,
when power is transmitted to the shaft, from a motor to be described, the chuck-
carrie and the stock therein are rotated The chuck-duving shaft is jour-
nalled at one end in a bracket a secured to the rear end wall of the bed, and at
the other end in a housing a attached to the bed and covering the gearing to be
subsequently described
The mechanism for rotating the shaft a¹s I shall hereinafter describe in detail,
but inasmuch as it is controlled or regulated by the movements of the tunet, 1
shall describe the latter first
Refering to Figs 2, 5, to 10, inclusive, and 32 and 33, the tunet e 18 shown
as plate-shaped and square in plan view with four intersecting grooves in the
upper surface thereof Two of the grooves c, are arranged diagonally and
extend from corner to corner, while the other two ², extend across the top of the
turret diametically, all of the said grooves intersecting at the center
Thus there are provided eight short grooves e¹, e, extending radially outwardly
from the center of the turret to receive the box- or other operating tools which
may be placed thereon and secured to the top of the turret by bolts or any other
suitable fastening devices. Four of the grooves are comparatively short, while
the diagonal grooves are considerably longer, whereby I am enabled to ɛceme

page_text: to the top of the turiet a greater number of operating tools than heretofore, since
the tools can be placed at different distances from the center of the tunet and
do not therefore interfere with one another
It is evident that other well known means for securing the tools to the turret
may be employed in lieu of the grooves though I prefer the latter in some cases
The square shape of the turret provides four edges which are substantially equal
in width to the chuck, and along any one of which one or more tools can be
secured to the top of the turret, and it is likewise evident that it is within the
scope of my invention to provide the tunet with a single edge instead of four,
or any other desnable number of edges
The turret is formed with a central aperture, into which is driven a downwardly
projecting studd, fitting loosely into the carriage, and the tunet is provided
with a cylindrical boss c³, with an outwardly extending flange c which in plan
view is located within the edges of the top portion of the carriage, as shown
in Fig 2. The carriage d, as shown in Fig 6, 18 provided with an upwardly
projecting annular flange d, upon which the upper portion of the tunet nests,
and into the cylindrical aperture in which the center-pin of the tunet hits, as
shown in Fig 10. To hold the tunet against upward movement caused by
angular strains, I provide a series of gibs, oi securing devices, each consisting of
a pin having a crescent-shaped head d, and a V-shaped groove at its lower
end The ring 18 1ccessed at to receive the said heads, the shanks of
the pins extending down into sockets therein, and lying outside of the flange c.
When the pins are in place, they are locked by horizontally aanged studs ",
engaging the lower walls of the grooves, and screws beaning against the
ends of the studs and diven horizontally into the edges of the catage The
heads of the pins overlap the flange, or take into the groove formed by the
said flange, as clearly illustrated in Figs 7 and 8 whereby the tunet is free to
1otate
When the tunet 18 secured in place in this way, it is practically impossible
for dust or dut to have access to the engaging parts of the turret, the caillage,
and the pawls, or to accumulate in recesses between the parts, as the tunet rests
upon the ing on flange d¹ which forms a housing for this purpose
To support
the corners of the square top portion of the tunet, I employ adjustable studs o
sciews 100 driven into the top of the caulage
The cauage for the turret is oblong in shape, as illustrated in Figs. 2 and 6,
and it is provided with gidores to receive the ways of shears b of the bed a
Guide strips or gibs are secured to the carnage and project underneath the
ways b, to prevent the calliage from being displaced, and to protect the sheats
from cuttings or filings, tubular casings oi coveis d³, d, are attached to the ends
of the camage and partially encicle the ways, as shown in Fig 4 I term the
covers for the ways "shear-protectors," and it will be seen that the front pio-
tectors pass fieely through apertures in the side wings a' in the head-stock or
fiont end of the bed, as shown in Figs 4, 17, and 34
Jounalled upon the stud on flange 18 a pinion having curved ratchet
teeth on its upper face, as shown in Figs 51 and 83, and arranged in a cncle in
bushings in the tunet are cylindrical pawls one for each tooth in the
pinion By 1otating the pinion in the direction of the arrow in Fig 83 the
turret will be rotated with it, whereas the rotation of the pinion in the opposite
direction will have no effect upon the tunet.
Inter meshing with the pinion is a rack 10 (see Fig 51,) which is aanged
longitudinally of the carriage and is adapted to slide in suitable guides therein
This 1ack and gear are adapted to have a limited movement before the ratchet-
teeth on the pinion reach then respective pawls
The rear end of the rack 18 substantially in the shape of an arrow-head
and when the car age approaches the end of its real ward movement, it slips
between sping latches on the end of a bai 13 mounted upon the cross-bai №
on the bed a, and abutting against the end of the bar, is held against movement.

page_text: When the end of the lack-bar engages the bar the continued movement of
the camage causes it to rotate the pinion, which in tuin iotates the tunet to
bing a new tool into operative position, and when the carnage starts forward
towand the chuck, the rach-bai 0 18 engaged by the spung latches d until the
pinion has been returned to normal position, after which the arrow-head du
Slides out from between the sping-latches as chown in Figures 2 and 51,
and the rack 18 called forward with the calliage
To hold the tunet with great igidity against movement while the tool is operat-
ing upon the work or stock in the chuck. I provide locking-dogs or index-
pins e, e, which are two in number and are mounted in bushings in the car-
11age, in the front and rear of the pivot stud d, said pins being normally thrust
upward to engage sockets e³ in the downwardly projecting portion of the turret c,
by spings e, placed beneath them
Heretofore only one index-pin was employed, but inasmuch as the center-
pin soon wole loose from the rotation of the tunet, the latter was not pio-
perly centered and held against vibration Consequently, by employing two
diametrically-opposite index-pins, the exact rotative position of the turret and
the location of the center are determined with great nicety, and a greater resist-
ance to the strains resulting from the engagement of the stock and tools 18
afforded
The pins are automatically withdrawn from engagement with the tunet, to
permit the latter to rotate at the proper time, by aims e³, e projecting laterally
from a lock-shaft e mounted in the carriage, as shown in Figs 51, 64, and 68
This shaft has an arm projecting laterally therefiom, on the end of which
there is a cam e', which when the dogs are in engagement with the turret is in
the path of a cam e' pivoted in the end of the rack whereby when the rack is
held against movement by its engagement with the bad, and the carriage
continues its movement away from the chuck and the work therein, the cam
18 thrust downwardly to rock the shatt e and lower the pins e out of engage-
ment with the tunet to permit it to rotate
The index-pins are not permitted to engage the turret until the next tool has
been bought into operative position, and to accomplish this, I secure to the
shaft another aim e which when the shaft e 18 10cked downward slips under
the head of a spung-held latch el mounted on the carriage, as shown in Figs 77
to 79. and holds the pins depressed
As before stated, the tunet has provisions for receiving eight different tools;
but of course the lathe is used many times when there are but three or fou
tools used successively upon the work Consequently, it may be desuable at
times to rotate the turret more than one-eighth of a 1otation and therefore the
tunet is provided with eight stops, each consisting of an adjustable screw e¹³ any
one of which may be diven down far enough to engage the top or head of the
latch ea and release the arm ell to permit the index-pins to again engage the
tunct If it 18 desued that the turret should be advanced one-eighth of a lota-
tion for each reciprocation of the carriage then all eight of the stops are screwed
down into operative position, but if there are less than eight tools, the stops
coliesponding to the tools employed are rendered operative, and the others aie
partially unscrewed, so that they will not engage the latch e.
I employ fluid-pressure, controlled by hand of automatically at will, for effect-
ng a forward and back movement of the canage By mechanism which I
shall describe, the carriage is advanced rapidly to bring the tool into position
to engage the work, and is then fed slowly forward at any desued rate of speed
until its work is accomplished Then an additional volume of fluid is utilized,
to rapidly return the carnage, whereby the time spent in withdrawing the cai-
riage, rotating the tunet and binging the next tool into operative position, is
vely short
Refering to Vigs 32 to 50, inclusive, and at first more particularly to Fig 33,
it will be seen that the carriage 16 formed with a fluid-cylinder f. extended

page_text: longitudinally thereof and atianged on one side of the central longitudinal line
of the machine
The end of the cylinder left open in the construction of the carnage 18 suitably
closed by a cylinder-head f' and packing f A stationary piston is centrally
perforated, and is rigidly connected to a comparatively small inlet-pipe f,
Though which fluid is admitted to the front side of the piston, for the purpose
of forcing the cariage for waid, or in the duction of the allow 3, toward the
work A larger pipe is connected to the piston, and is provided with ports f
in its inne end, to admit fluid to the real side of the piston, to force the cal-
1lage
the dnection of the allow
fom the work.

The
In
pipes Or tubes pass though the elinde-head f¹, and ale igidly
gecured in the cross-ba d in the end of the bed a The outer end of
the tube f is closed by a suitable head through which the tube f* projects,
there being suitable packing, as indicated, surrounding the last-mentioned tube
Liquid is automatically admitted to the tube f, though a duct extending
though the cross-bai, as indicated in the last-mentioned figure. The tubes f
and are respectively connected with a valve casing g by pipes f, fto, shown
particularly in Figs 45 to 49. inclusive, and the valve g is automatically
operated to admit Hund, first into one of the pipes, and then into the other, as
will be afterwards explained The valve casing is supported on the end of the
bed, and the inlet in the valve casing is connected with the force pump cylin-
ders h, h, supported on the head-stock by a pipe h¹ having the bianches h*, h',
leading to the said pump cylinders, the last mentioned parts being clearly
illustrated in Fig 12 The pump cylinders h, h, are on the ends of the aims h', h
of a bracket h³ secured to the housing at of the head-stock, as shown in Fig 12,
and the piston-10d his connected midway between its ends to a slide passing
through guide-slots or apertures h8, 8, in the ends of said aims h. as shown in
Fig 38 Passing through the bracket h is a roch-shaft having on its end a
crank-aim A10 A link is connected to the end of the crank am by a bolt ¹ª
and to the slide by a bolt h¹³, which likewise connects the slide to the piston-
rod so that when the shaft his rocked, the piston his reciprocated to force
fluid into the inlet pipe, before referred to, from a supply there being
suitable valves, as shown in Fig 40
To rock the said shaft, an aim h is loosely secured thereto, and is connected
by a pitman od 15 to a clank-pin 16 on a pinion intermeshing with the
pinion a before referred to as being secured upon the end of the chuck-driving
shaft as which furnishes motor power to the chuck-carrier Consequently, so
long as the chuck is being rotated, the arm is oscillated The hub of the
said arm 18 formed with ratchet teeth 18, and upon the cranh-aim 1 which 18
laterally extended, as shown in Figures 40 to 42, are pivoted two
inwardly extending pawls, 20, which operate to connect the crank-arm to the
aim h, whereby, when the aim ¹ is oscillated, the ciank-aim is caused to move
with it
By swinging the arm 10 to one side on the other relatively to the aim the
pivot stud may be swung to one side on the other, so as to vary the length of
movement of the piston, and thereby increase or decrease the volume of fluid
delivered by the pump to the inlet ducts, and vary the rate of speed at which
the carnage travels forward during the time that the tool in the tuiiet is operat-
ing The aim " has always the same arc of movement, and consequently, the
arm ho must have the same, but by changing the position of the said arm ho,
to cause it to move in a path across the path of movement of the piston, the
movement of the latter will be greatly decreased in length, as will be readily
apparent And hence, to effect a movement of one of the aims relatively to the
other, and to accomplish this automatically, I provide the following devices.
Loose upon the lock-shaft is a partial gear a provided with a V-shaped
recess formed by two inclined walls. The pawls 19, 20, are provided with
outwardly projecting pins h, which extend to the recess in the partial gear,

page_text: When it is desired to adjust the relations of the two arms 10, 114, the partial
gear is rotated slightly to one side on the other, and one of the pawls h¹ or 20
is lifted out of engagement with the ratchet-toothed hub 18 of the arm
whereby only one-half of each reciprocation of the arm is effective until the
crank-arm 18 moved relatively thereto by the operative pawl so that both
pawls ho, ho, are in engagement with the toothed hub
The partial gear is operated automatically by mechanism under the control of
the turret, which I subsequently describe, through the medium of a rack
connected to a chain, both passing through the end of the bed, as shown in
Figure 34. A spring surrounds the end of the 1od and abuts at one end
against a collar thereon, and at the other end against the bed
The volume of fluid from the pumps, which 18 varied to suit the character of
the work being done by the tool, passes into the valve casing, and is deflected
into either of the two feeding ports f. f, to move the carriage in one direction
or the other. The pump which is thus interposed between the source of fluid
supply and the valve mechanism, operates as a measuring device to supply a
predetermined volume of fluid to the cylinder, and it is actuated simultaneously
with the work-holder by the devices previously described. Each movement of
the piston measures off a predetermined volume of fluid which is fed into the
cylinder
Refering more particularly to Figures 45 to 49*, inclusive, a valve gis
shown, which is adapted to permit the entrance of fluid from the pipe ¹ into the
pipes, alternately, there being an outlet or escape duct communicat
ing with a discharge pipe h27, and the ducts being so aanged that when fluid
18 flowing through the pipe into the cylinder on the front side of the piston,
the liquid on the rear side of the piston is being discharged through the pipe 27,
(see Figure 46), and when fluid is entering the rear side of the piston f³ through
the pipe the fluid on the front side of the piston 19 escaping through the
tube f into the said outlet, as shown in Figure 46 I have not deemed it neces-
sary to describe in detail the exact construction of the valve casing, nor the
location of the ports therein, as the details of construction in this feature of my
lathe are not necessarily essential, and I may employ any suitable valve mech-
anism in place of the one shown.
The valve 18 provided with a stem which 18 reduced at its end, as at 9' A
collar is placed upon the said end and between it and the shoulder ³ on the
valve stem, a spiral spring 7 is placed so that when the centrally pivoted
lever g is swung about its fulcrum to oscillate the valve to the left in Figure 45,
the latter is moved with a yielding pressure
+
The lever has on its upper end a pin 98, taking into the slot 9 in the end
of an arm 10 keyed to the projecting end of the shaft, as shown in Figures 53
and 54 This shaft a mounted upon the turret carriage to travel therewith,
and it extends through the cross-bar d on the bed, and inasmuch as it must
slide through the arm go, the latter is pinned to a sleeve g feathered on the
shaft and mounted rotatably in a bracket g, as shown in Figure 54
The inner
end of the sleeve gl s flanged and lies between the bracket and the cross-bai d¹
on which the said bracket is mounted, whereby the shaft is free to slide through
the sleeve without effecting a longitudinal movement thereof although when the
said shaft is rocked, it effects a movement in or out of the valve g¹.
t
The rocking movement of the said shaft is effected automatically by the car-
riage, as I shall now proceed to explain, there being means, corresponding to
each tool on the tunet, for stopping the forward movement of the carriage by
shifting the valve.
Referring again to Figures 60 to 69, it will be seen that the shaft is in aline-
ment with the rock-shaft 7 herein before described, and that it is provided with
a laterally projecting arm close beside the arm e on the shaft e The arme
18 provided with a stud which projects over the aim ¹ and limits the upper

page_text: movement thereof, there being in the carriage a sping-held pin, which engages
the arm when it is depressed, as shown in Figure 70, and prevents the upward
movement thereof, unless positively actuated There is likewise a spring-pressed
pin mounted in a thimble in the arm which normally projects into the
socket in the arm so as to connect the two aims together The end of the
arm is slotted as at 7 to permit the end of the pin to he engaged and thrust
backward out of the socket
Mounted in the bed are a plurality of stop-rods one for each tool or groove
of the turret, and each having its inner end 29 (see Figure 62) recessed to form
a stop, and mounted immediately above the said rods on the camiage are a
plurality of movable pawls or stops 10 so that if any one of the latter were
allowed to drop down to the position shown in Figure 62. it would engage the
stop-rod immediately thereunder Each of the movable stops or pawls 10 is con-
nected by a ball and socket joint with a lever 1, all of the said levers being
fulcrumed upon a cross-bar supported in the carriage, and having grooved
rollers.
The tappet-rods 18, one for each lever 21 and pawl 10 are mounted in the
carriage, and their ends project under the upper portion of the turret c They
are arranged to engage depressions or sockets 24 (Figures 5 and 61,) in the under
surface of the ton portion of the turret there being a special socket for each of
the tappet-rods 213 When the turret is at a state of rest, on the carriage, and
the latter is being advanced, one of the sockets is immediately over one of the
tappet-rods, whereby its stop or pawl 10 is allowed to drop into the notch in
the ston-rod immediately thereunder when the carriage reaches the desired end
of its forward movement
of
The movable stops 10 are all pivoted upon a shaft having its ends jour-
nalled in a frame 16 extending between arms 217 of the bracket 18 in which the
cross-bar 18 mounted, (see Figures 66 and 57) The frame 716 is pivoted in the
said arm immediately above the shaft 71%, and it is provided with an arm 10,
which, when the frame 16 is 1ocked. is depressed, as shown in Figure 62 The
end of the arm projects over the end of the arm ¹, just above the slot 27
therein, and rests lightly upon the end of the spring-pin Consequently.
when one of the movable pawls drops so as to engage the notch in the end
one of the stop-bars at the time when the carriage has reached the desired end
of its movement towards the chuck. or has moved forward a predetermined dis-
tance, its engagement with the said end swings the frame 1 backward to move
downward the forward end of the arm 218, and thereby forces the spring-pin
ont of the socket i, depresses the end of the arm far enough to rock the
shaft i, and shifts the valve to permit the flow of fluid from the pump to the rear
de of the piston Therefore, by adjusting the stop-bais 8, the carriage may be
fed towards the work a predetermined distance for each tool, and when the
movable stop engages the stop-bar, the downward movement of the arm 19 forces
downward the arm ¹, and rocks the rock-shaft, to shift the valve g and cut
off the flow of liquid to the pipes and f
The arm is held downward by the engagement of the spring-pin there-
with, until, when the carriage approaches the end of its movement away from
the work, the rock-shaft is rocked by the device previously described,
whereupon the spring-pressed pin enters the socket, and as the index-pins
slip into their bushings in the turret, the arm 2 18 1aised and the rock-shaft
again rocked to throw the valve in the opposite direction and deflect the flow of
fluid into the pipe 10 and cause the carriage to be fed forward.
For causing the initial rapid movement of the carriage to bring the tool into
position to engage the work and to bring it away from the work I employ an
auxiliary pump which is indicated conventially upon the drawing in Figure 45,
and which may be driven from an independent source of power or from the motor
of the lathe.

page_text: The supply-pipe from the said pump 7 enters the valve casing g at the left
end thereof, as shown in Figures 45 to 48, inclusive, and to deflect the fluid
therefrom to the let duct or to the outlet duct h, there is a valve which
18 movable independently of the valve gl
are
The bushing, in which the valves 7 and operate 18 provided with a pai-
tition which is apertured at into which aperture a small piston 6, on the
end of the valve o may enter to engage the projection on the end of the
valve. Leading from the chambeis on both sides of the partition
vents 8, 1, and it is thus seen that the chambers provide, as it were, a dash-pot
1esistance to the movement of the valves and That is to say, when either
piston closes the aperture, the chamber is temporarily closed too, for the fluid
therein escapes slowly and consequently the movement of the piston and the valve
18 checked
passes
The movement of the valve q m one duection to permit the fluid to pass from
the auxiliaiv pump into the inlet is eftected by the inward movement of the
valve after it has overcome the dash-pot resistance As the piston
through the aperture in the partition and engages the projection on the
valve, it foices the valve over far enough to register with the port and the
inlet poit, and the valve will remain in this position until thrust automatically
in the opposite duection by mechanism to be described.
Consequently, when the carriage is being fed forward, during the time when
the tool is operating on the work, and until the movable stop ieaches its abut-
ting notch, the additional volume of fluid is cut oft from the front side of the
piston, but when the carnage reaches the end of its predetermined movement,
the valve is moved by welding pressure to permit the entrance of the fluid
in additional volume to the rear side of the piston
The yielding pressure of the valve is made by the dash-pot resistance which
permits the turiet to move forward to the end of its stroke long enough for the
tool to nicely smooth up the shoulder on the work to which it is travelling As
the resistance of the dash-pot decreases by the escape of the cushioning substance
through the vent, the valve goes over the full distance and besides opening the
port to the pipe f10, also engages the valve, and forces it into position to pei-
mit the quick feeding volume of Huid to pass from the auxiliary pump into the
Inlet and thence into the rear side of the piston to effect the return of the
tuiret-caillage
'
The auxiliary pump continues to force fluid into the inlet until upon the
forward movement of the can age, the valve 18 thrust in the opposite duection
by the bell cank lever, which is pivoted at in the end of the valve-
casing.
The bell-crank lever is connected by a link with a centrally pivoted
lever having a yielding latch 7, with which is adapted to coact any one of a
series of stops on a rotating stop-cartier movable in unison with the turret
The turret, as shown in Figure 10, is provided with a bevel-toothed ring in
its under sui fare which intermeshes with and dives a bevel-geai on a shaft
projecting through the side of the carriage On its end this shaft has a spial
gear intermeshing with, and diving a spal gear on an inclined shalt L
jainalled in a bracket carried by the camage Spiral geais 14, 17, impart
power from the shaft to a longitudinally grooved shaft mounted in bear-
ings supported by the carnage and bracket on the bed. Upon this shaft 18
is a grooved stop-carrier A in which there may be placed as many steps as
there are tools, and the stops are adjustable so that they may be brought to
engage the latch end on the end of the lever 16 at that point in the move-
ment of the catage towards the chuck when the tool is about to begin its work.
Consequently, if the carriage 18 to be advanced half its movement before, the tool
engages the work, the stop is arranged not to engage the latch 17 until the
cariier reaches that point In other words, the stops are adjustable with
relation to each other, just as are the stop-rods on the bed, so that as soon as

page_text: the tool with which a stop coresponds is about to begin its work, the valve 13
35 operated The stops are brought successively into alinement with the latch-
lever as the tunet is rotated, and the latch is aanged to be operated by the
for waid movement of the canlage, and to yield when the cuillage is moving in
the opposite direction
From the mechanism which I have thus fai descubed, it will be seen that the
calage will be fed towards the work, rapidly until the tool is ready to engage
the work when one of the stops will engage the lever and operate the
valvoto cut off the fast-feeding volume of fluid Then the cannage will be
fed slowly forward as the tool performs its allotted work
As the tool finishes its work, the carriage is automatically stopped in its for-
waid movement and is called rapidly away from the work, and in its reluin
movement, the turret is rotated, but it is not until the index-pins have entered
then bushings in the tunet that the valve 91 18 operated to turn the fluid into
the ports which cause the feeding of the tuner towards the work
The auxiliary means to accelerating the movement of the calliage is thrown
into or out of operation at any desired time, being under the control of two sets
of stops, of which one set on the bed causes it to be thrown into operation when
the tool finishes its work, and the other, on the rotating stop-carrier, causes it to
be thrown out of operation after the tunet has been notated, the camage has
been advanced, and the next tool is about to begin its work And, too, the con-
trolling mechanisms are directly governed by the movement of the tunet,
whereby the auxiliary means is thrown into o out of operation in accordance
with the time it takes each tool to perform its allotted duty, or the relative
positions of the stock and the tool.
I shall now proceed to describe the motor for 1otating the chuck-came and
the mechanism by means of which the chuck may be kept at a constant desired
speed respective of the resistance of the tool on the work
The motor consists of a wheel m, as shown in Figs 15 and 16 It is provided
with a series of sets of concentric blades m', the blades being curved and at an
inclination to the face of the wheel, as shown in Fig 16 The wheel itself
18 11gidly secured to a shaft m³ which projects through the casing m³ in which
the water-wheel m is confined, into the housing a of the lathe, being journaled
in the bracket at before referred to
Two nozzles m m³ are employed, one for duecting a stream of liquid against
the concave sides of the blades to propel the wheel in one duection, and the
other being aanged to duect the water against the convex side of the blades to
propel the wheel in the opposite duection The nozzles are swiveled in the
casing so as to swing radially of the water-wheel whereby the stream of fluid may
be directed against any one of the series of pockets for furnishing a differential
movement to the said wheel
That is to say, the nozzles are provided with the stud mh journaled in one side
of the casing and the pipe m² journaled in the other side and registering with
the pipe from which the liquid is supplied There is a valve m8 at the junction
of the nozzles which is opciated by a lever to tuin the water into either of
the two nozzles, the last-mentioned lever being itself operated by a Imk m
connected to a hand-lever m¹ fulciumed to the bed in a position easy of access
to the operative The lever m" is pivoted to the stem of the valve so that the
parts are not caused to bind when the nozzles are swung upon their center of
movement
The stud m6 is connected to a shaft m which is journaled in one of the sup-
ports of the bed and is provided with a laterally extended arm m by which it
18 rocked to vary the position of the nozzles
By a mechanism which I shall now describe, and which is controlled by the
turret, the shaft m¹³ 18 rocked automatically to adjust the nozzles m³, m³, and
thereby vary the power transmitted by the motor to the chuck-carriei.
A shaft which I have previously described as being rotated in unison with

page_text: which co-act with the tappet-rods, and which are supported upon the tilting
frame, and mounting the said frame in the said extended end of the carriage.
Another desirable feature of the lathe is, that the controllers for the back-
gear or gearing for the chuck-carier, the pump, the motor, and the quick-feed-
ing mechanism are all actuated from a single shaft geared to the turret, and
co-acting therewith, the controllers for the "back-gear" and the valve which
regulates the passage of fluid from the auxiliary pump to the feeding cylinder
being mounted directly upon the shaft itself
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:-
1 A turret lathe having a flat, square-topped turret with provisions for sup-
porting operating tools at or near the corners of its upper surface
2 A turret lathe having a polygonal flat-topped turiet with provisions for
receiving tools at or near the corners of its upper surface.
3. A turret lathe comprising a chuck, and a flat-topped turret arranged to
pass beneath the work, said turret having at least one edge substantially the
width of the chuck and also having provisions for supporting tools on its upper
surface along the said edge
4 A turret-lathe having a flat-square-topped turret, with intersecting dingonal
and diametrical grooves in its top surface, to receive the operating tools
5 A turiet-lathe having a flat-topped or plate-shaped turret adapted to pass
beneath the work, said turret being square in plan, and having provisions for
receiving tools on its upper surface, along one or more edges
A turret-lathe having a plate-shaped square turiet, with grooves in its face
extending diagonally between its corners and diametrically between its sides, to
receive the operating tools, and means for supporting the corners of the said
turret
7. A turret-lathe comprising a square-plate-shaped turret with a depending
cylindrical portion, a cairage having a cylindrical depression to receive the said
portion, said turret extending over or overlapping the edges of the carriage,
means for journaling the turret at its center in the carriage, and additional
means for supporting the corners of said turret
8 A turret-lathe comprising a plate-shaped turret with a depending cylin-
drical peripherally-giooved portion, a carnage having a cylindrical depression
to receive said portion, and in which said turret is journaled and held against
angular strains, means for centrally journalling said turret on said carriage, and
gibs located below the surface of said carriage and entering the said groove in
said cylindrical portion of the turret
9 A turret-lathe comprising a turret having a flat top to receive the tools 4
thereon and a depending flanged ring, a carnage, a central bearing for journal-
ing said turret on said carriage, said carriage having a socket to receive said
ring and an annular flange for the outer edges of the top of the turret to rest
upon, and means on the carriage taking over the 1ng to secure the furiet to the
carriage
10 A turret-lathe comprising a plate-shaped turret having a depending boss
with a peripheral groove, a carnage having an annular depression for receiving
and affording lateral support for said grooved bess, and gibs taking into the
groove to secure the turiet rotatably to the cairiage

with a peripheral flange, a carriage having an annular ring or flange to receive
the boss and which is overlapped by the top of the turret, said flange being
formed with sockets, and gibs arranged in said sockets and taking over the said
peripheral flange

with a peripheral flange, a carriage having an annular ring or flange to receive

page_text: entuely self-controlled, or self-acting, and which will perform in order a series
of operations upon a piece of stock, rotating the chuck and the stock, and
advancing the carrier, at a rate of speed desirable for the tool operating on the
stock whereby the presence of an attendant or operator, save for the purpose of
scouring the work in the chuck, is practically unnecessary
f
Regarded as a whole, the lathe possesses many features of advantage over
others, heretofore used, not only by reason of its being automatic, but by reason
of its being able to more accurately finish the work, if a nicety of operation is a
requisite, on else to 1ough out" ou "chuck out" work to be finished in another
machine. The peculiar form of chuck-carrier adds greatly to the accuracy of
the lathe, which is also insured by the turret and the mechanism which secures
it in place The chuck-carer being journaled at or near its center, as well
as near its outer edges, is held against the slightest movement save that of 1ota-
tion, and consequently, the work is 10tuted relatively to the cutter or other tool
with accuracy and precision And the turret 18 similaily guarded from move-
ment under angular strain for it is not only journaled at the center, but it is
gibbed to the carriage at its outer edge The construction of the turret and
the carnage by which the gibs and the parts within the turret and carriage are
housed and guarded from an accumulation of dust and cuttings prevents the
delicate and operative parts from being injured, and ensures an even and easy
movement of the tunet The turet, after being rotated, is centered with great
accuracy by two index pins, instead of one, and is rigidly locked in place thereby
with the proper tool in position to operate upon the stock in the chuck
The form of the bed and head-stock which I have shown and described possesses
many obvious advantageous features among which are its provisions for support-
ing the rotating chuck-canie at its outer edges The bed and head-stock are
hown as formed in one casting but it is evident that they may be cast in any
desned number of pieces
It is unnecessary to specifically mention the advantages acciuing from the use
of the automatic controller for the auxiliary-liquid-supply by means of which
a rapid movement of the carriage is attained, nor to point out the beneficial
results obtained by the employment of the automatic controller for regulating the
movement of the pump-piston, and consequently the volume of fluid delivered
from the pumps to the carnage-feeding evlinder, by means of which the work-
ing feed of the carnage is regulated in accordance with the character of the work
being done by the operative tool, as they are apparent to those familiar with
lathes of the class, it being sufficient to state that thereby no time 18 lost in
withdiawing the carriage to tuin the turret for the presentation of another tool,
and returning it to the stock, and that the lathe is rendered entirely automatic,
work of different kinds and character being performed by the cutters as per-
fectly as though the machine were under the constant control of the hand of the
operator And in addition to the movement of the tunet-carriage being regu-
lated to the character of the work, the 1otation of the chuck-cairie is changed,
or the carrier is held at a state of rest when the work is completed, or to permit
an inspection of the stock
One thing to which I desire to call attention in connection with the feeding of
the carriage, is, that by the mechanism which I employ, the carriage is not
started forward until the index pins have fully entered their respective bushings
in the turret, the movement of the valve which controls the passage of fluid into
the feeding cylinder being dependent upon, and simultaneous with the move-
ment of the said pins
It will be observed that the movable stops on the bed with which the tappet-
rods (controlled by the turret) co-act to shift the valve and reverse the move-
ment of the carriage, are located under the carriage so that they are covered and
protected from cuttings at the extremes of movement of the carriage, this being
accomplished by extending the carriage rearwardly, and lengthening the rods

page_text: around an idler p* mounted upon the lower end of the arm pe depending from a
bracket attached to the head-stock The level 18 engaged by stops på
adjustably mounted on the stop-carrier 18. The means for securing the stops in
place consist of two clamping members, one of which 18 screwed into the
carter, and a screw po
From the description just given, it will be seen that the motor and the pump
are both automatically controlled, by controllers co-acting with, or actuated by
the turret, so that the speed at which the carriage is moved as well as the speed
of rotation of the chuck are automatically regulated, and hence, after the
machine has been once adjusted, each tool will be advanced at the proper rate
of speed, and the chuck will be driven in accordance with the work to be done by
the said tool It will be observed that the two slides n and p are equi-distant,
and consequently, it results that the levers n¹8, 12, are also equi-distant from the
shaft n and hence the stud-shaft n³ is mounted to one side of the axis of the
shaft n, so as to provide two concentric circles of stops ³ 18, on the stop-
carrier n³, which are eccentric with reference to the shaft n, whereby the said
stops may properly engage the levers
Although I have described the motor and the chuck, yet I have not described
the gearing for transmitting power from the motor-shaft me to the chuck-driving
shaft 15, and shall now proceed to do so I provide the mechanism shown in
Figures 16, and 21 to 28, inclusive Rigidly secured to the shaft m³ are two
gears, of different diameters. and meshing therewith are two gears,
mounted loosely upon the chuck-diving shaft a¹, a sliding sleeve between the
said gears being adapted to cause the clutching of either of them to the
shaft The mechanism interposed between the said sleeve and the said gears is
of any suitable type To slide this sleeve, I employ a centrally pivoted lever
the upper end of which has a projection extending into a groove therein and
the lower end of which has a similar projection extending into the groove in a
sleeve, sliding loosely upon the motor-shaft m² This sleeve has a circumfer
ential flanger, which is extended laterally at its um to form a diamond-shaped
cam 78
Four plungeis 9,1,ale mounted in the brackets, supported
upon the housing 17, and are each adapted to be thrust forward to engage the
cam by a spring as shown in Figures 21 and 22, said spring being mounted
in a socket therein. If when the parts are in the position shown in Figure 16,
the plunger ⚫ be allowed to move forward to engage the cam 8, as the cam
revolves, the sleeve will be forced thereby so as to unclutch the gear from
the shaft a while the plunger would have to be projected against the sleeve
to move it far enough to effect the clutching of the gear to the shaft 15. The
plungers effect similar movements of the sleeve in the opposite duection
The plunges are held in their inoperative positions by pawla, engaging
shoulders thereon, said pawls being connected by links of trackers with
centrally pivoted levers, the pivot on which the said levers are mounted extend-
ing out to the end of the bracket 1 In this last-mentioned bracket is placed
a bushing in which is rotatably mounted a stop-carrier t (Fig 28) though
which the grooved shaft passes, and to which it is keved The stop-carrier is
in the form of a cylinder and it is reduced to receive the bushings, whereby
it is held against longitudinal movement as the shaft slides therethrough It
is longitudinally grooved, there being as many grooves as there are atops n³,
or 28, and the stops t¹ mar be secured in the band grooves in position to engage
any one of the said levels ¹ Therefore, as the turret is 1otated, any one of
the plungers may be released to effect a movement of the sleeve, thus throwing
either clutch into operation, according to the speed required, or else bring it to
a state of rest To return the plungers to then normal position the flange
is provided with another cam which 18 wide enough to engage the ends of the
plungers and force them back into the position shown in Figure 23
From the foregoing, it will be observed by any one skilled in the art to which
this invention relates, that I have provided a machine which may be, if desired,

page_text: the turret and as moving with the carriage, passes through the hub of a gear n
journaled in bushings n in the bed (Fig. 28), and splined to the shaft so as to
turn therewith and permit longitudinal movement of said shaft therethrough.
The gear intermeshes with and drives a toothed stop-carrier n², journaled loosely
upon a stud-shaft n³ projecting forward from a bracket n secured to the side
of the bed
This stop-carrier is provided with a series of axially arranged pins or stops n³,
equi-distant from each other, and each held adjustably in place by a set-screw ne
There are eight of these stops, and they are brought one by one into operative
position each time the turret is rotated provided eight tools are employed.
On
The bracket n before referred to, is formed in two parts, one secured upon
the other, as shown in Fig 13. A shaft n' having one end journaled in a stan-
dard n³ arising from the motor casing, is journaled at its other end in a block n³,
secured in the said bracket (see Fig. 28) and it is formed with a worm or screw-
threaded portion n10 which rotates in a chamber or socket in the bracket
the inner side of the shaft n', the bracket is provided with a way n¹¹ to receive
a slide n, which is placed therein. and in which is transversely mounted a slid-
ing hollow pawl or nut section 14 having its end threaded to register with the
threads on the shaft n', but normally disengaged therefrom This slide n¹ is
provided with a screw-stud n15, which projects laterally through a slot n in the
side of the bracket, and is connected by a chain or rope, or other flexible con-
nection 16, which passes over a pulley ", journaled in a stud extended out from
the bracket, with the arm m¼ before referred to, there being a weight m15
attached to the said arm
The slotted end of the slide 1 is hollow to receive the end of a lever 18 which
is pivoted at its centre therein and one end of which extends into an aperture in
the hollow-nut section A screw 19 is passed through the outer end of the nut
section, and bears against the end of the lever, there being a spring n on the
its pivot the nut-section 19 forced vieldingly into engagement with the sciew n10
other side of the said end of the lever, so that when the lever is swung about
A spring placed in the socket in the lever 18 tends to normally hold the
nut-section out of engagement with the worm on the threads on the shaft n³.
Now it will be seen. that by adjusting the stops n to the desired position each
time the ston carrier is rotated, one of them will be brought into engagement
with the end of the lever n¹³, and thereby force the nut-section into engagement
with the worm no whereby the rotation of the shaft n', which is accomplished
by means of a belt o passing around a belt-wheel o¹ thereon and around a
similar wheel on the shaft m³, causes the slide to be moved in the direction of
the arrow in Figure 28, against the stress of the weight until the outer end of
the lever slips off the end of the stop, whereupon the nut-section is immediately
drawn out from engagement with the worm The slide is prevented from
returning under the pull of the weight at the end of a chain by the stop n
engaging the end of the lever
When the turret is again turned, however. and the stop-carrier 18 rotated.
immediately upon the stop leaving the end of the lever, the slide n returns to
its original position, before the next stop n³ engages it Thus, it will be seen
that the position of the nozzle is easily controlled by varying the length of the
stops n³
The mechanism as above described may be said to be automatically actuated
or operated to deliver a variable volume of fluid to the fluid-operated carriage-
feeding means, in accordance with the character of the work, done by the operat-
ing tools, and in addition to being turret-controlled, is likewise governed by
adiustable stops on the stop-carrier or controller
On the outer side of the shaft 7, I mount a similar slide . eauipped with o
nut-section, and lever ². similar to those just described. This slide 18
connected with the chain before referred to which controls the action of the
pump, said chain being connected thereto by the threaded stud p³, and passing
