Improvements in Lathes or Metal Working Machines.
I, REGINALD HADDAN of the Firm of Herbert. Haddan & Co. of 18
Buckingham Street Strand W.C. London Patent Agent do hereby declare the
nature of this invention a communication to me from abroad by James Bruce
Clyne of Cleveland, Ohio, in the United States of America, Mechanical Engineer,
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 improvements in lathes or metal working machines, more
especially designed for making screw-nipples used in the attachment of the spokes
of a bicycle wheel to the wheel-rim etc.; and it consists in certain features of
construction, and combinations of parts hereinafter described and pointed out in the
claims.
In the accompanying drawings,
Fig. 1 is a top plan of a machine embodying my invention. A portion of shaft N'
is broken away in this fig. to more clearly show the construction."
Fig. 2 is a top plan, partly in section, of the greater portion of the machine..
Portions are also broken away in this fig. and the parts are illustrated on a larger
scale than in Fig. 1.
Fig. 3 is a right hand side elevation, relative to Fig. 2, and portions are broken
away and in section in this fig. to more clearly show the construction.
Fig. 4 is a front side elevation, relative to Fig. 2.
Portions are broken away
and in section in this fig. to more clearly show the construction.
Fig. 5 is a vertical section on line 5-5, Fig. 2 looking in the direction of the
arrow.
Fig. 6, is a vertical section on line 6-6, Fig. 2, looking in the direction of the
arrow.
Fig. 7 is a section of the tool stock, its shaft, rotary sleeve upon said shaft, and
the means employed for establishing operative connection between the tool stock
and said sleeve and for reciprocating said stock longitudinally.
Referring to the drawings, A (see Figs. 1 and 7) designates the work holder that
is rotated in any approved manner. It is not considered necessary to show the
mechanism for rotating the work, because the same forms no part of my present
invention.
B designates the tool stock that is suitably mounted upon a horizontally arranged
shaft suitably supported from the stationary frame work C of the machine. In
the case illustrated the tool stock is mounted upon one end of shaft and has
bearing in a box C¹ rigid with frame work C, and the shaft, at or near its opposite
end, is supported, as will hereinafter appear. The tool stock, within its tool
bearing end, is provided with any suitable number of pockets Bi (see Fig. 7) for
the reception of tools (not shown) required in the operation of the machine.
I would here remark that work of the character indicated, such for instance, as
screws, nipples, etc., is made from wire or metallic rods, and the wire or rod is
automatically fed through the work holder while it is rotated with the work holder,
and that in the manufacture of said work, two or more tools are required. The
tools should be advanced slowly in performing their function, and to increase the
capacity of the machine, should be rapidly withdrawn from the work after the
performance of their function, and the different tools employed in the formation.or
construction of a piece of work are required to be advanced at different speeds

page_text: respectively. The tool receiving pockets B₁ and consequently the tools (not
shown) of the tool stock, are arranged at suitable intervals about the axis of the
stock, and the arrangement of parts is such that the axis of the tool stock is located
such a distance out of line with the axis of the work holder that the tools of the
tool stock shall be adapted to be brought successively into engagement with the
work (not shown) to be operated upon. A sleeve D (see Fig. 7) is loosely mounted
upon the tool stock bearing shaft a suitable distance from the tool stock. Sleeve D
has bearing in a box C rigid with the frame C, and is provided with two aunular
shoulders d d at opposite ends, respectively, of said box, which shoulders prevent
end wise displacement of the sleeve.
A worm wheel D' is operatively mounted upon sleeve D and meshes with a
worm E formed upon the driving shaft E. A sleeve F (see Fig. 7) is loosely
mounted upon the tool stock bearing shaft between the tool stock aud sleeve D.
Sleeve at one end engages the tool stock and at its other end engages an
annular shoulder or collar & formed upon the tool stock bearing shaft and a collar
is formed upon shaft b at and engages the outer end of the tool stock, by which
construction the tool stock and its supporting shaft are moved end wise or longi-
tudinally with sleeve F when the latter is reciprocated as will presently appear.
Operative connection between sleeve F and sleeve D is established in any approved
manner for instance, by horizontal pins D² suitably secured to sleeve D and
projecting into corresponding holes F extending through sleeve F. One of pins D'
is provided at its free end with a dog or projecting member that is adapted to be
engaged upon one side by a similar dog or projecting member B2 formed or
constructed upon the rear or inner end of the tool stock, when the latter is moved
inwardly or rearwardly with sleeve F and the supporting shaft. Sleeve F upon
its periphery is provided with a groove F1 that is engaged by a roller suitably
supported from the supporting frame of the machine. Groove F¹ extends circum-
ferentially of the sleeve and has such trend that the sleeve during its rotation is by
means of the engaging roller caused to reciprocate end wise, resulting in the
reciprocation of the tool stock bearing shaft and consequently the tool stock as
required to advance the operating tool during its operation, and to withdraw the
tool from the work after it has performed its function, and the arrangement of parts
is such that when the tool stock is moved rearwardly or withdrawn from the work
after the tool has performed its function, operative connection is established between
said stock and sleeve D through the medium of dogs or projecting members B
and d² and the tool stock is thereupon given the fractional turn required in order
to bring the next succeeding tool into position for operation, and the trend of
groove is furthermore such that immediately upon the actuation of a tool of the
tool stock into position for operation, the tool stock, and consequently the tool, shall
be moved forwardly or advanced as required during the operation of the tool. To
prevent circumferential displacement or vibration of the tool stock during the
operation of the tool, means for positively locking the tool stock in the operative
position of the tool is provided, and consists preferably of an upright bolt G (see
Fig. 7) provided at its upper end with a head G' adapted to snugly engage longi-
tudinal grooves or recesses B³ formed in the periphery and arranged longitudinally
of the tool stock, and a spiral spring G2 suitably confined upon said bolt, acts in
the direction to retain the bolt in its operative position. The tool stock is provided
with as many recesses or grooves B33 as there are tool receiving pockets B₁ and the
arrangement of said grooves or recesses is such that one of them is opposite the
head of the bolt in the operative position of any one of the tools with which the tool
stock is provided. Bolt B extends downwardly through the adjacent portion of
the stationary part of the machine, and at its lower end is operatively connected
with the outer end of the vertically tilting lever g that is fulcrumed at its opposite
end as at g' to a stationary member of the machine and at any suitable
point
between its fulcrum and outer end supports an upright pin or member that
extends upwardly through the adjacent portion of the stationary part of the
machine, and at its upper end is provided with a roller g³ adapted to be engaged

page_text: by a cam or projection F formed upon the periphery of the sleeve F and the
arrangement of parts is such that said cam shall have come into engagement with
roller g and shall have depressed pin g to actuate the engaging lever g in the
direction and to the extent required to render bolt G inoperative immediately
before operative engagement is completed between the tool stock and the
rotating sleeve D.
The driving shaft E whose speed is to be controlled or regulated is shown:
arranged horizontally and at right angles to the tool stock bearing shaft. Shaft E
is supported in any approved manner from the supporting frame of the machine
and a sleeve E2 (see Figs. 1 and 2) is loosely mounted upon one end of said shaft.
Said sleeve E is shown journalled in a box C³ rigid with the stationary frame
work of the machine. The driving pulley E3 is operatively mounted upon the
inner end of sleeve E2 at the inner end of box C³ and said pulley is rapidly driven
preferably by means of a belt E from a countershaft (not shown). Sleeve E² at
its outer end terminates in a friction disc E that is preferably integral with the
sleeve, and anti-friction balls Es are preferably confined between said disc and the
outer end of box C3 around sleeve E³.
H designates a suitably supported shaft a suitable distance below and preferably
in the same vertical plane as shaft E. Shaft H is arranged horizontally and
parallel with shaft E and extends a suitable distance beyond the friction disc
bearing end of shaft E.
A friction dise H' is operatively mounted upon the outer
end of shaft H, and a suitably supported friction roller I is interposed and
operatively engages the opposing flat faces of discs E' and H', whereby motion is
communicated from discs E to disc H', said friction roller being movable radially
of the overlapping portions of the discs. The diameter of the driven disc H¹ is
preferably such that said disc extends upwardly opposite, or nearly opposite the
central portion of disc E' (see Figs. 3 and 4). Shaft H at its inner end is pro-
vided with a gear H2 (shown in dotted lines in Fig. 4) that is operatively mounted
upon the shaft and operatively engages a system of differential gearing J independent
of shaft E and providing for effecting a great reduction in the speed of the tool
stock when the said system of gearing which may be of any approved construction
is operatively connected with the shaft.
It will, therefore, be observed that shaft E and consequently the tool stock
actuating sleeve D is rapidly driven when operative connection is established
between the driving pulley and said shaft, which rapid movement is desirable
during the idle movements of the tool stock. When however the driving pulley
is not operatively connected with shaft E and operative connection is established
between said shaft and the system of differential gearing motion will be com-
municated from the driving pulley to said shaft E through sleeve E, dise E³,
friction roller I, friction disc H₁, shaft H, gear H2, and system of differential
gearing, in which case said shaft E and consequently the tool stock, is actuated
very slowly as required during the advancing or working movement of said stock.
A clutch for establishing operative connection between the driving pulley and
shaft E is provided, and another clutch for establishing operative connection
between said shaft and the system of differential gearing is also provided.
Toothed clutches are employed in the case illustrated and referring firstly, to
the clutch employed for establishing and interrupting operative connection between
the driving pulley and shaft E, K (see Fig. 2) designates the movable member
of the clutch and K' the relatively stationary member of said clutch. Clutch
member K' consists preferably of tooth shaped beads formed upon pins K² that
are employed in establishing operative connection between said pulley and its
supporting sleeve E2, which pins engage holes e in the hub of the pulley and
recesses or grooves e in the supporting sleeve. Morable clutch member K is
preferably integral with a sleeve L operatively and slidably mounted upon shaft E,
and said sleeve is provided with an external annular groove L that is engaged by
a ring L preferably made in halves and operatively engaged by two set screws m
arranged at opposite sides respectively of sleeve L, and extending through

page_text: correspondingly threaded holes M¹ (see Fig. 5) formed in the different members
respectively of the forked end of an arm M that is loosely mounted or fulcrumed,
at its lower end upon the horizontally arranged shaft M' supported in any
approved manner from the stationary frame work of the machine a suitable distance
below.
Referring to the clutch employed for establishing operative connection
between shaft E and the system of differential gearing, & designates the movable
member of said clutch, and the relatively stationary member of the clutch.
Member is operatively connected with said system of gearing in any approved
manner and member k is rigid and preferably integral with sleeve L to which
reference has already been made. It will therefore, be observed that the movable
members of both clutches are operatively connected with one and the same sliding
sleeve L, and that operative engagement is established between the members of
the one or the other clutch, according as said sleeve is actuated into the one or the
other of its extreme positions, and that the movable members of both clutches are
disengaged from their companion and relatively stationary members when the
sleeve is in its intermediate position. It follows, therefore, that the driving pulley
or the system of differential gearing is operatively connected with shaft É
according as sleeve I is actuated into the one or the other of its extreme
positions.
Suitable means for automatically actuating sleeve L is provided and comprises
preferably the following:-
A horizontally arranged shaft N' is arranged at right angles to and a suitable.
distance above shaft E, (see Figs. 1. 2. 3. and. 4) and is suitably supported from
the supporting frame of the machine. A drum N is operatively mounted upon one
end of said shaft N and said drum is suitably intergeared with sleeve D by means
of a spur gear D* operatively mounted upon sleeve D and meshing with a gear
wheel n formed upon the periphery of drum N. Drum N, upon its inner face is
provided with two series and respectively of inwardly projecting pins or
members. Said series of pins or projecting members are arranged concentrically
with the axis of the supporting drum and the members of each series are arranged
at suitable intervals. In the case illustrated n¹ designates the outer series and
212 the inner series. The members of the outer series n of drum pins are adapted
during their revolution to engage an incline or shoulder O¹ formed or constructed
upon an arm or lever O (see Figs. 2 and 4) that is operatively mounted upon
shaft M2. A shoulder or incline O2 is also formed or constructed upon said lever
and is adapted to be engaged by the members of the inner series of drum pins n².
The shank of one of set screws m extends a suitable distance beyond the outer side
of the supporting arm of the forked end of arm M, (see Fig. 5) and said set screw
between its head and shank is provided with an annular beveled shoulder m².
An upright arm or lever M³ is operatively mounted upon shaft M below said
long set screw, and said arm or lever M³ at its upper end embraces the shank of
the set screw in the normal position of parts, and the hole m³ in said arm or lever,
and through which the set screw extends, is somewhat larger in diameter than the
diameter of the embraced portion of the shank of the screw, as shown in Fig. 5
and the arrangement of parts is such that when lever M and consequently sleeve L
are in their intermediate position the aforesaid set screw shall extend through the
central portion of hole m and hence, when shaft M and consequently lever M³
is actuated into the one or the other of its extreme positions there is some lost
motion before said lever is brought into operative engagement with the screw, and
consequently into operative connection with the forked arm M and sleeve L.
Inclines or shoulders O, O' are engaged alternately by one of the respective
pins, non drums N, and lever O, and consequently shaft M and lever M are
actuated in the one direction or the other according as incline or shoulder O¹ or
shoulder or incline O is engaged by one of the drum pins. The engagement of
incline or shoulder O by one cf pins n depresses lever O and thereby actuates
shaft M' and its arm or lever M in the direction of the driving pulley, and said

page_text: ever O is elevated upon the engagement of in-line or shoulder O¹ by one of pins n
nd thereby actuates shaft M2 and lever M³ in the direction of system of differential
earing. Pins n' and n² of drum N are not capable of actuating arm M and the
novable clutch members K and the distance required to establish operative
engagement between the members of either clutch and in order to actuate lever M³
nd consequently sleeve L in the one or the other of their extreme positions, as
or the other of the
equired to establish operative engagement between one
lutch members operatively connected with said lever and sleeve, and the
companion clutch member sone means for establishing or throwing lever O
farther than said lever is thrown by pins n n is provided, and consists
or inclines 03 and 0 (see Fig. 4) suitably
preferably of two shoulders
The
formed or constructed upon and at or near the free end of lever O.
trend of incline or shoulder 03 is downwardly and in the direction of the
free extremity of the lever, and the trend of shoulder or incline O' is upwardly
and in the direction of said extremity of the lever so that both inclines converge
and meet, or substantially meet, at their adjacent ends. Incline O³ is adapted to
be engaged by a corresponding incline P formed upon the head P¹ of a hori-
zontally arranged pin P that is adapted to move end wise of the chamber C of a
box C rigid with the stationary frame work of the machine. Head P of pin P
is also provided with another incline P³ that corresponds with and is adapted to
engage incline O upon lever O: Inclines P3 aud P therefore converge in the
direction of the outer end of pin head P1 and meet or substantially meet, at
their adjacent extremities and the arrangement of parts is such that incline O³ of
lever O engages incline P of pin P or incline O' of said lever engages' incline P³
of the pin according as clutch members K and K or clutch members k and k¹
operatively engage each other and in the case illustrated in Fig. 4, incline 03 of
lever O engages incline P of pin P when clutch members K and K' operatively
engage each other, and hence, incline O is engaged by incline P³ when clutch
members kk' operatively engage each other.
The arrangement of parts is therefore, such that when lever M 3 and conse-
quently sleeve L are in the one or the other extreme position and operative
connection is established between one of the clutch members operatively connected
with said sleeve and the companion clutch member, incline or shoulder O 3 or
shoulder or incline O 4 is engaged by the corresponding incline on pin P, and the
parts are furthermore so arranged and timed that when the position of parts is as
just described, the next succeeding drum pin will, during the rotation of said drum
actuate lever O so as to move the meeting or adjacent extremities of shoulders or
inclines O 3 and 04 of said lever opposite and a trifle beyond the meeting ends of
inclines P 3 and P 4 of pin P, and thereby actuate said pin P against the action of
a spiral spring P 2 suitably confined upon said pin, and acting to retain the pin in
its advanced or normal position, and when the adjacent ends of inclines or
shoulders O 3 and 04 have thus been actuated to traverse the adjacent ends of
inclines P3 and P 4, lever M3, and consequently sleeve L, shall have been
actuated into the intermediate position or approximately intermediate position,
5 (wherein the movable clutch members K and k are located centrally between the
relatively stationary clutch members) whereupon the recoil of said spring P 2 will
throw the engaging pin P forwardly so as to bring the other incline thereon into
engagement with the corresponding incline or shoulder upon lever O, and thereby
establish operative connection between the members of that clutch that was lastly
0 rendered inoperative, and hence, it will be observed that the driving pulley and
the system of differential gearing are alternately operatively connected with
shaft E as required in the operation of metal working machines of the variety
indicated.
Suitable means for rendering lever O inoperative, that is for moving said lever
$5 out of the way of the annular paths of the lever actuating pins n' and n³ of drum N,
and for locking the sleeve L and the connected movable clutch members in their

page_text: intermediate and inoperative position, should be provided, and consists preferably
of a horizontally arrangel shaft Q that is suitably supported from the supporting
frame of the machine a suitable distance below and at right angles to shaft M 2
(see Figs. 4 and 5) which shaft Q at one end is provided with a hand wheel Q1 or
other means for turning the shaft. Sail shaft, directly below shaft M 2 is shown
provided with a cam or eccentric Q 2, the peripheral surface whereof is straddled
or engaged by the lower forked end of an arm or lever M 4 operatively mounted
upon or connected with shaft M 2 Arm or lever M 4, in its normal position, which
it assumes during the operation of the machine, operates idly during the operation
of the machine, but the arrangement of parts is such that shaft M2 by means of
the cam or eccentric upon shaft Q and the engaging shaft arm or lever, can, upon
turning said shaft Q in the required direction, be shifted end wise in the direction
required to move lever M³ over the head of the embraced set screw, and to shift
lever O and the shoulders or inclines thereon inwardly away from pin P and away
from the annular paths of pins n' n² of drum N, and the head of the aforesaid set
screw is preferably large enough to fit the hole in the embracing lever and thereby
remove the lost motion had between the lever and screw. Lever O, upon its inner
side is also provided with an inwardly projecting lug or pin Os that, when said
lever is actuated from its operative to an inoperative position, enters a hole C
formed within a stationary lug or member C of the supporting frame (see Figs. 1,
2, and 6) and thereby locks said lever and the connected parts in the in-operative
position of said parts. Lever M³ is shown engaging the head of the embraced set
screw in dotted lines Fig. 5.
Drum N, upon its peripheral surface or at any other suitable place is provided
with cams N2 that are adapted to engage the roller R¹ borne by the one arm of a
bell crank lever R that is fulcrumed at R2 (see Fig. 3) to any suitable stationary
member of the machine. The other arm of said lever at its outer end is provided
with a segmental gear or rack r that meshes with an upright rack S formed upon a
vertically sliding sleeve Sl suitably mounted and adapted to slide endwise of an
upright stationary post or rod Cs, and friction roller I is supported in any approved
manner from said vertically sliding sleeve. A spiral spring S² suitably confined
upon said upright post or rod C between the upper end of sleeve S¹ and a
shoulder or collar C formed upon and at or near the upper extremity of said rod
or post, is preferably provided and acts to depress the engaging roller bearing
sleeve.
The speed of shaft H, and of shaft E when the latter has the system of
differential gearing operatively connected therewith is it will be observed increased
or decreased according as roller I is shifted from the central portion of disc E
and outer portion of disc H¹ toward the axis of the latter and periphery of the
former or according as roller I is shifted toward the periphery of disc H' and
axis of disc H. Čams N' that form a cam wheel upon or at the outer face of
drum N have such trend and shape as required to actuate the segmental rack
bearing lever in the direction required to elevate the friction roller bearing sleeve
and thereby reduce the speed of shaft H and connected parts and spring S2 that
is compressed by sleeve Si when the latter is elevated acts as already indicated in
the direction required to depress said sleeve and thereby increase the speed of
shaft H and connected members when said depression of the sleeve is permitted by
the cam wheel and the spring of course, acts to retain the roller of the segmental
rack bearing lever in engagement with the cam wheel. Hence it will be observed,
that in my improved machine the regulation of speed of shaft H and cousequently
the regulation of speed of shaft E when the latter is operatively connected with
the system of differential gearing that operatively engages shaft H is automatic.
I would also remark that a spiral spring T as shown in Fig. 4 is preferably
confined upon shaft H in any approved manner and presses against a collar h fixed
upon said shaft a suitable distance inwardly from disc H and thereby acts to
retain disc H' in the desired frictional engagement with roller I..
