useful Improvements in Lathes or Metal-.

WVorking Machines; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in lathes or metal-working machines more es pecially designed for making screws, nipples used in the attachment of the spokes of a bicycle-wheel to the wheel-rim, &c.; and it consists in certain features of construction and combinations of parts hereinafter described and pointed out in the claims.

Inthe accompanying drawings, Figure l is a top plan of a machine embodying my invention. A portion of shaft N is broken away in this figure 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 figure and the parts are illustrated ona 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 figure 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 figure to more clearly show the construction. 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 side elevation 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. sidered necessary to show the mechanism for rotating the work, because the same forms no part of my present invention.

13 designates the tool-stock that is suitably mounted upon a horizontally-arranged shaft Fig. 5 is a vertical section on line 5 5,

It is not con- 1) suitably supported from the stationary framework C of the machine. In the case illustrated the tool-stock is mounted upon one end 'of shaft 1) and has bearing in a box C rigid with framework C, and the shaft at or near number of pockets B (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 indicatedsuch, for instance, as screws, nipples, &c.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 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 orconstruction of a piece of work are required to be advanced 'at different speeds, respectively. The toolreceiving pockets B, 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 workholder that the tools of the tool-stock shall be adapted tobe 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 frame C, and is provided with two annular shoulders 01 cl at opposite ends, respectively, of said box, which shoulders prevent endwise 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-bearin g shaft between the tool-stock and sleeve D. Sleeve F at one end engages the tool-stock and at its other end engages an annular shoulder or collar 1),

formed upon the tool-stock-bearin g shaft, and a collar U is formed upon shaft Z) at and engages the outer end of the tool-stock, by which construction the tool-stock and its supporting-shaft are moved endwise or longitudinally 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 D suitably secured to sleeve T) 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 (1 that is adapted to be engaged upon one side by a similar dog or projecting member 13*, 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 supportingshaft. Sleeve 1 upon its periphery is provided with a groove F that is engaged by a roller f, suitably supported from the supporting-frame of the machine. Groove F extends cireumferentially of the sleeve and has such trend that the sleeve during its rotation is, by means of the en gagin g-roller, caused to reciprocate endwise, resulting in the reciprocation of the tool-stoclebcntring 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 ithas 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 1) through the medium. of dogs or projecting members 13 and (Z 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 F 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 re quired, 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 longitudinal grooves or recesses 3 formed in the periphery and arranged longitudinally of the tool-stock, and a spiral spring G suitably confined upon said bolt, acts in the direction to retain the bolt in its operative position. The toolstoek is provided with as many recesses or grooves B as there are toolreceiving pockets B, 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 G extends downwardly through the adjacent portion of the stationary part of the machine and at its lower end is opcratively connected with the outer end of the vertieally-tiltin g lever g, that is fulerumed 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 9, adapted to be engaged by a cam or proj ection F, formed upon the periphery of sleeve F, and the arrangement of parts is such that said cam shall have .come into engagement with roller and shall have depressed pin to actuate the engagin 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 toolstock-bearing shaft. Shaft E is supported in any approved manner from the supportingframe of the machine, and a sleeve R (see Figs. 1 and 2) is loosely mounted upon one end of said shaft. Said sleeve E is shown journaled in a box C rigid with the stationary framework of the machine. The drivin pulley E" is operatively mounted upon the inner end of sleeve Wat the inner end of box C", and said pulley is rapidly driven, prefe'rabl y by means of a belt E, from a counter-shaft. (Not shown.) Sleeve E at its outer end terminates in a friction-disk E, that is preferably integral with the sleeve, and antifriction-balls E are preferably confined between said. disk and the outer end of box C around sleeve E II designates a suitably-supported shaft a suitable distance below and preferably in the same vertical plane as shaft E. Shaft II is arranged horizontally and parallel with shaft E and extends a suitable distance beyond the frietion-disk-bearing end of shaft it. A friction-disk II is operativel y mounted upon the outer end of shaft II, and a suitably-supported frictionroller I is interposed and operativcly engages the opposing ilat faces of disks E and II, whereby motion is eonnnunicated from disk E to disk ll, said frictioii-roller being movable radially of the overlapping portions of the disks. The diameter of the driven disk II is preferably such that said disk extends upwardly opposite, or nearly opposite, the central portion of disk 111. (See Figs. 3 and 4.) Shaft II, at its inner end, is provided with a gear 11 (shown in dotted lines, Fig. 4,) that is operativel y mounted upon the shaft and operatively engages a system of differential gearing J independent of shaft E and provided 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 operative] y conmotion will be communicated from the driv' ing-pulley to said shaft E through sleeve E disk E friction-roller l, frictiondisk H, shaft H, gear H 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, first, to the clutch employed for establishing an interruptin g 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 heads formed upon pins K that are employed in establishing operative connection between said pulley and its supporting-sleeve E, which pins engage holes 6 in the hub of the pulley and recesses or grooves e in the supporting-sleeve. Movable 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 two set-screws or arranged at opposite sides, respectively, of sleeve L and extending through correspondingly-threaded holes M (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 horizontallyarranged shaft M supported in any approved manner from the stationary framework of the machine a suitable distance below and ar ranged parallel with shaft E.

Referring to the clutch employed for establishing operative connection between shaft E and the system of differential gearing, 7i designates the movable member of said clutch, and 7c the relatively stationary member of the clutch. Member is operatively connected with said system of gearing in any approved manner, and member 71", 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 thedriving-pulley or the system of differential gearing is operatively connected with shaft E according as sleeve L 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 4B,) 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 it formed upon the periphery of drum N. Drum N upon its inner face is provided with two series, a and n 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 ar ranged at suitable intervals. In the case illustrated a designates the outer series and n the inner series. The members of the outer series, at, of drum-pins are adapted during their revolution to engage an incline or shoulder 0 formed or constructed upon an arm or lever 0 (see Figs. 2 and 4) that is operatively mounted upon shaft M A shoulder or incline O is also formed or constructed upon said lever and is adaptedto be engaged by the members of the inner series of drumpins 11 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 m An upright arm or lever M is operatively mounted upon shaft M below said long set-screw, and said arm or lever M at its upper end embraces the shank of the set-screw in the normal position of parts, and the hole m 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 M 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 conse IIO quently into operative connection with the forked arm M and sleeve L. Inclines or shoul ders n n are engaged alternately by one of the respective pins of 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 O, or shoulder or incline O is engaged by one of the drumpins. The engagement of incline or shoulder O by one of pins 01 depresses lever O, and thereby aetuates shaft M and its arm or lever M in the direction of the driving'pulley, and said lever O is elevated upon the engagement of incline or shoulder O by one of pins or, and thereby actuates shaft M and lever M in the direction of the system of differential gearing. Pins 01- and 11. of drum N are not capable of aetuatin g arm M and the movable clutch members K and 7c the distance required to establish. operative engagement between. the members of eitherelutch, and in order to actuate lever M, and consequently sleeve L, in the one or the other of their extreme positions, as required to establish operative engagement between one or the other of the clutch members operatively connected with said lever and sleeve and the companion clutch member, some means for establishing or throwing lever 0 farther than said lever is thrown by pins n n is provided, and consists preferably of two shoulders or inclines O and 0 (see Fig. 4) suitably formed or constructed upon and at or near the free end of lever 0. The trend of incline or shoulder O" 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 O is adapted to be engaged by a corresponding incline P, formed upon the head P of a horizontallyarranged pin P that is adapted to move endwise of the chamber 0 of a box C, rigid with the stationary frame work of the machine. Ilead 1 of pin I is also provided with another incline P that corresponds with and is adapted to engage incline 0' upon lever O. Inclines P and P therefore converge in the direction of the outer end of pin-head P and meet, or substantially meet, at their ad j acent extremities, and the arrangement of parts is such that incline O of lever O engages incline P of pin P, or incline O of said lever e11 gages incline P of the pin, according as clutch members K and K, or clutch members 7a and k, operatively engage each other, and, in the case illustrated in Fig. 4, incline O of lever O engages incline P of pin Pwhen clutch members K and K operatively engage each other, and hence incline O is engaged by incline P when clutch-members 7a 7a operatively engage each other. The arrangement of parts is therefore such that when lever M and eonsequent-1y 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, or shoulder or incline O, is engaged by the corresponding incline on pin 1, and the parts are furthermore so arranged and timed that when the position of parts is as just described the next succeeding pin of drum N will, during the rotation of said drum, actuate lever 0 so as to move the meeting or a ljacent extremities of shoulders or inclines O and O, of said lever opposite and a trifle be yond the meeting ends of inclines P and 1" of pin P, and thereby actuate said pin 1 against the action of a spiral spring P suitably eonfined 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 and 0' have thus been actuated to traverse the adjacent ends of inclines l and 1" lever M", and consequently sleeve L, shall have been actuated into their intermediate position, or approximately intermediate position, (wherein the movable clutch members K and 7a are located centrally between the relatively stationary clutch 1nembers,) whereupon the recoil of said spring P will throw the engagingpin P forwardly so as to bring the other incline thereon into engagement with the correspondin incline or shoulder upon lever O, and thereby establish operative connection between the members of that clutch that was lastly rendered inopera tive, and hence it will be observed that the driving-pulley and the system of dillerential gearing are alternately operati vel y 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 out of the way of the annular paths of the levcractuating pins or and n of drum N, and for locking sleeve L and the connected movable clutch members in their intermediate and inoperative position-should be provided, and consists preferably of a horizontally-arran ged shaft Q that is suitably supported from the supporting-frame of the machine a suitable distance below and at right angles to shaft M (see Figs. 4 and 5,) which shaft Q, at one end, is provided with a hand-wheel Q or other means for turning the shaft. Said shaft, direct] y below shaft M is shown provided with a cam or eccentric Q", the peripheral. surface whereof is straddled or engaged by the lower forked end of an arm or lever M" operatively mounted upon or connected with shaft M Arm or lever M 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 M 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 endwise in the direction required to move lever M 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 n 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 0, upon its inner side, is also provided with an inwardly-projecting lug or pin 0 tl1at,when said lever is actuated from its operative to an inoperative position, enters a hole 0' formed Within a stationary lug or member 0 of the supporting-frame, (see Figs. 1, 2, and 6,) and thereby locks said lever and the connected parts in the inoperative position of said parts. Lever O is shown in its inoperative position in dotted lines, Figs. 2 and 6, and lever M 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 N that are adapted to engage the roller R borne by the one arm of a bell-crank lever R that is fulcrumed at It (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 0 that meshes with an upright rack S formed upon a vertically-slidin g sleeve S suitably mounted andadapted to slide endwise of an upright stationary post or rod 0 and frietion-roller I is supported in any approved manner from said vertically-sliding sleeve. A spiral spring 8*, suitably confined upon said upright post or rod C between the upper end of sleeve S and a shoulder or collar 0 formed upon and at or near the upper extremity of said rod or post, is preferably provided and acts to depress the engaging-roller bearingsleeve.

he speed of shaft H and of shaft E when the latter has the system of differential gearin g operatively connected therewith is, it will be observed, increased or decreased according as roller I is shifted from the central portion of disk ll and outer portion of disk H toward the axis of the latter and periphery of the former, or according as roller I is shifted toward the periphery of disk H and axis of disk E Cams 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-rollerbearing sleeve and thereby reduce the speed of shaft II and connected parts, and spring S that is compressed by sleeve S when the latter is elevated, acts, as already indicated, in the direction to depress said sleeve and therebyincrease the speed of shaft II and con nected 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 the speed of shaft H, and consequently the regulation of the speed of shaft E when the latter is operatively connected with the system of diiferential 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 disk H, and thereby acts to retain disk H in the desired frictional engagement with roller I.
