To all 107mm t may concern.' l

Be itknown that we, VILLIAM C. LoRrNG and Crmnmis E. JAconsoN, citizens of the VUnited. States, `residing' at Hartford and Manchester, in the county of Hartford and State cf Connecticut, have invented certain new and usefulk Improvements in Metal- 1Werking Machines, of which the following is aspeciication. Y

This invention relates to metal-working machines. p invention is the provision of several mechanisms or as they might be considered, a plurality of machines combined in one unit, although it will be understood that when they are se combined or associated they lose their identity as machines, although they individually perform Vthe respective functions of such machines. Said mechanical elements r mechanisms may be of any-suitable nature, for instance one may function as a "lathe, another as a milling-machine and still another as a 'drill-press.

As will be clear the mechanisms might be of some other character, although we have combined in one unit, a machine capable of exercising respectively the functions' of a lathe, a milling-machine, and a drill-press. It is conceivable that the sub-mechanisms of the severa-l which are associated in a unit, maybe utilized to secure other results; it isralso conceivable that we may employ in conj unction with a milling mechanism, a lathe mechanism and a drill-press mechanism, a mechanism of a kind different from the other three mechanisms or the Vmechanisms ide.4 iiied by name. The invention as may be inferred comprises certain broad relatiens.

ln the drawings accompanyingand forming a part of the present specification we have fully shown one of the several forms ef embodiment of the invention which, to enable these skilled in the art, to practice the same will be set forth fully in the following'description. We are not limited to this disclcsure as we may depart therefrom in several respects withinthe scope of the invention defined by the claims following said description.

Referring to said drawings:

Figure l -is a perspective View as seen practically from lthe front of a machine invclvin the invention.

The fundamental object of they Fig. 2 is a like View as seen from an end orside, for example the left side or end of Fig. 1.

the arrows.

Figs. 6, 7, S, and 9 are cross sections 'on the lines 6 6, '7-7, 8--8 and 9-9 respectively of Fig. 4; the arrows `indicating the points of view.

Fig. l0 is a detail view of certain driv 'ing mechanism.

Like vcharacters refer to like throughout the several views which are on Vdifferent scales. v,

The machine which we have selected for illustration, is triplex in function.v It is adapted to carry into effect` the operaticns of a milling-machine, a lathe, and a drillparts' press as will be readily understood, these be- 'i ing merely three of many'examples. matter of fact it may not always be necessary to employ three and there may be instances where a less or a larger number may be employed. The plurality of mechanisms may be operated simultaneously or separately as desired by the user of the machine Gbviously we secure in a unit all the advantages of several distinct classes of metalwerking mechanisms. y

The framework for carrying the different parts of the machine may be of any suitable character. As shown, it comprises a base or bed as 3, and a column or pedestal as 4c, the

two parts being rigidly united in some con- As a.

being hollow or chambered te incase and inclose certain of the operative parts of the machine. This framing is best shown in Figs. l and 2 and it also appears in other views.

Y There is necessarily a `driver or motor from which as desired lone or more of the separate mechanisms receives its or theirl we indicate, a driving means or motive effect we can produce in many different Ways as will be clear, although a belt drive meets our conditions. Above this driving shaft 5, as we have considered it, is a shaft as 6.

which may be considered as the prime motor. This shaft 6 is tubular or hollow as shown best in Fig. 4 and it is'supported as will later appear, by a bearing as 7 rising from the base or bed 3. Said tubular shaft 6 receives within it, the inner ends of a lathespindle as 8 and a milling mechanism spindle as 9. The bearing 7 to which we have referred, has depending portions 10 and 11 which constitute bearings or sustaining means for thc two co-axial spindles 8 and 9, there being between these bearings 10 and 11, bearings 12 and 13 rising from the base or bed and which sustain the intermediate portions of the spindles 8 and 9 res ectively all as shown clearly in Fig. 4. he bearing 10Vand 12 to which we have referred act really as the head stockV of the lathe mechanism of the machine, while the bearings 11 and 13 act similarly as the support for the spindle 9 of the milling mechanism as shown for instance in Fig. 4, and arbor or spindle 14 as shown in Fig. 1.

This arbor 14 as will be understood, carries a cutter or a gang of cutters as is usual in milling machines, the cutter or cutters.

acting on the work which is clamped to a reciprocating table hereinafter described in a manner familiar to those versed in the metal-working art. The bearing end of this arbor 14 is supported by an overhanging arm as 15 which extends from the bearing 7 as shown in Figs. 1 and 4. The chuck or work holder 16 which is common in lathes, is connected with the nose or bearing end of the spindle 8. The inner ends of the two spindles 8 and 9 are closely arranged as shown in Fig. 4 and they adjoin and support the tubular shaft 6. The driver or pulley 17 is shown as mounted upon the 'y hollowshaft 6 in Fig. 4 which driver may be suitably driven as by a belt (not shown). As represented, the hub of the driver or pulley 17 has a lateral extension 18 to which is lkeyed or otherwise suitably fastened, a

power-transmitting member such as a pulley 19, connected as by the belt 20 with the driven member 21, '(Fig. which is also shown as a pulley fixed in some convenient f way to the shaft 5. It will be clear that when the pulley 17 is rotated it acts through the intermediate described parts, to rotate the driving or main shaft 5 which is entirely separately operative from the spindles 8 and 9 as shown. Said spindles 8 and 9 are adapted to be operatively connected with the said shaft 5 for action thereby as we will hereafter explain.

equipped with the usual accessories quite common in lathes. The lead-screw of the lathe portion or mechanism, is designated by 25 and it functions with the usual adjuncts on the carriagepor slide 24, as Vcustomary in lathes of the ordinary-type.

l The automatic action ofthe lathe 'isf Y brought about by a feed `shaft as 26. VThis lfeed shaft, as a matter of fact, is common in lathes, so that it is not necessary for usgto describe the way in which it is associated v with the carriage or slide 24, to effectthe automatic traverse thereof. It will beV understood of course that on the operation of the feed shaft 26, they carriage' or' slide is advanced or retracted in accordance with the direction in which the shaft 26 is turned. The rear ends of the lead screw 25 and the feed -shaft 26, as shown (Fig. 5) extend into the box or casing 27.

We have represented as feathered, or splined to theshaft 26 for movement longitudinally on said shaft, a spur gear Vas .28 which coperates with an intermediate spur gear 29 adaptedto co-act with any of the sections of the cone gear 30, xed to the extension of the lead screw 25. The several gears and coperati'ng parts which werare now describing are inclosed inthe casing or box 27, which as will be understood, is rigid with the frame 3 ofthe machine. An idler gear las 29 isrotatively supported as shown by the lever 31, fulcrumed on the feed shaft 26 within the box 27, the handle or upper end ofthe lever projecting through aslot 32 in the top of the box. By manipulating this lever 31 the idlergear 29, can

beV thrown into,v mesh withinv any desired one of the sections of the cone gear .30, as

common in lathes. VThe feed shaft 26 theref fore receives its motion-from the lead screwV 25, which is in turnrrotated in somerconvenient manner, one way of accomplishing which we will now set forth. Y

There is shown, as fastened to the lead screw 25 in the box 27 the bevel gear 33 in mesh with the bevel-gear 34, fastened .to the shaft 35, it being understood that the bevel-gear 33 is rigid with the lead screw 25.`

3) the bevel gear 36 in mesh with of the shaft 38 can be accomplished in oppon site direction it follows that the carriage or slide 24 can be reciprocated.

The trains of gears shown (Figs. 6, 7 and 8) as we will later set forth, are intended to advance at the will of the operator, the carriage or slide toward the headstock in Fig. 1, the train of gears shown in Fig. 9, being intended to effect a backward movement of the carriage or slide 2. The trains of gears shown in these severalFigs. 6 to 9 inclusive, will cause the reciprocation of the carriage or slide 24; Their fundamental purpose however, is to effect variations in movement of the spindle 8, to which it will be remembered the chuck 16 is rigidly connected. We obtain variation in velocity between the feed shaft 26 and the spindle 8 by shifting the gear 29, so as to bring it into mesh with any desired section of the cone gear 30. ObviouslyV the shaft 38 is connected with the lathe spindle 8 in some convenient way, belt gearing being shown for the purpose. l The shaft 38 has fastened to it a pulley as`39, over whichA a belt as 40 is placed, this belt also passing around the pulleyv 41, keyed or otherwise fastened to the lathe spindle 8.

The shaft 5 (Fig. 6) is shown connected to theshaft 38 bya train of gears of spur type, each as a matter of convenience being designated by 42. These gears 42 are intended to effect through the intermediate described parts, the rotation of the shaft 38 at its maximum speed and the consequent maximum speed of the spindle V8.Y The gears of the intermediatel speed train are each for the same reason denoted by 43, and they are of spur type also. The gears of the low speed train, also of the same type, are designated by 44. Any one of the three trains to which we have -just referred, is y put into or out of action by the movement laterally of the members of one vof vthese trains. We have shown (Fig. 1) a lever as 45 by which this movement of a selected gear in any one of the three trains may be accomplished., and the same lever is also utilized for throwing into or out of action the gears 46 (Fig. 9) of the reverse train shown in Fig. 9. At will therefore, the lathe spindle 8 may be rotated forward at different speeds or velocities, or may be reversed while changesin speedV may be independently secured Vwith respect-to the carriage or slide 24.

The main shaft 5 (Figs. 3 and 4) as shown, has fastened to it in some suitable way, the bevel gear 47 in mesh with the .bevel gear 48 fastened as represented to the lower end of the inclined shaft 49, supported at its lower extremity, by bearings on the frame and at its upper end extending into a box as 50 (Fig. 3) onrthe column 51, rising from the framework 3. The shaft 49, as illustrated, has fastened to its upper end, within the box or casing' v50, the driver 52, shown as a spur gear, and in constant mesh with a driven gear 53 on theA jackshaft 54, mounted in the box or case 50. There is splinedv to this jack-shaft 51 a series of` gears each denoted by 54 5 of different diameters and which are adapted to be moved longitudinally of said jack-shaft 54, to put them into mesh with cooperating gears 55, on the shaft 56 the lower end of which is spaced from-the upper end of wthe shaft 49, but is coaxial therewith. The

shaft 56 can therefore, as will be seen, through one of the sets of gears 54, be driven vat different speeds to effect through coacting mechanism, corresponding movements of the spindle 57 (Fig. 3) of the drill press portion of the machine. As represented, the shaft is connected by meshing mter gears'58 with the stub shaft 59 rotatively supported at the upper end of the arm 60, rising from the lupright or column 51, the front end of the shaft 59 being connected as by bevel gears denoted in a general way by 61, with the upper end of the spindle 57, which has the usual adjustments, and which may be provided with the customary means for carrying va drill or other tool.

The milling mechanism spindle 9, may in like manner receive its motion in any .convenient manner, although what might be considered its primary source, is a power transmitting member in the form of a shaft 62, (Fig. This shaft 62 is adapted to be driven forward at different speeds, or reversed at will, as we will later explain, although it is proper atV this time to observe that the rotation of said shaft 62 is brought about from'the primary or main shaft 5, through mesliing'gears arranged inl trains for the purpose, and shown in detail in Figs. 6 and 9 inclusive. The shaft 62 (see Figs. 3 and 4) has a belt connection with the milling mechanism `spindle 9. As represented, said shaft 62 has fastened to it the pulley 63 connected as bythe belt 64 with the pulley 65 fastened to the milling mechanism spindle 9, so that it follows that when the shaft 62 is rotated, the spindle 9, will be also rotated, its speed, or direction of movement, depending on which one of the trains of gears (Figs. 6 to 9) is in action.

The shaft 5 (Fig. 6)v is connected by a train of meshing gears as 66 with the shaft 62 the initial gear of ksaid train being also the initial gear of the train 42. This train of gears 66 is what is utilized to drive the shaft 62, and hence the spindle 9 at its maximum speed. In Fig. 7 we have shown be-V tween the shaft 5 and the shaft 62 the intermediate train of gears 67, the initial gear of which as in the other lcase'is utilized in the train of gears 44. In Fig. 8, we have shown the low speed trai-n for the spindle 9, the gears of which are denoted by 68, the first gear of this train being common to the train 45 already described. This train of gears 68 is what is utilized to rotate the spindle 9 at its low speed. The gears of the reversing train (Fig. 9) are denoted by 69, and Vthey are driven from a primary on the shaft 5. The several trains of gears shown in said Figs. 6, 7, S and 9,V by which the spindle 9 is driven forwardly at variable velocities or reversed, are thrown selectively7 into action through suitable means, acting on one of the gears of each train.

le have shown in Fig. 2 a reclprocatory `table as 7 O of the milling mechanism.A This in practice will be equipped with means of lsome convenient kind to bolt, fasten, or

otherwise hold work thereto which is being milled by the cutter, fastened to the arbor lll. This table is reciprocated through suitable agencies receiving their motion from4 the shaft 71, arranged at an' inclination, and

having as represented, fastened to its lower end a bevel gear 72 in mesh with the bevel gear 73, which with the companion gear 7lv is fastened to a stubV shaft 75, the several gears and stub shaft being carried in a box 76 which raises and lowers with the work carrying table as the same is adjusted up and down. The bevel gear 77, issplined to the upright shaft 7 8, the lower end of it, or that carrying the gear 77, beingdisposed in a vertically movable box 76. There is also feathered to the upright shaft 78, the bevel gear 79, in mesh with the bevel gear 80, fastened to the tail-end of the feed screw 26, so that it will be clear, when said feed shaft 26 is being' rotated, the power necessary to effect the action of the milling feed mechanism is brought into being.

It will be clear from the foregoing descriptionV taken in connection with the annexed drawings that a machine involving the invention comprises a plurality of mechanisms operatively assembled into a single unit and each capable of performing a function different from another or others of said mechanisms, and means by which any one of said mechanisms may be put individually into action or several of them into action at. the same time.

v These mechanisms desirably are of some character VOfwOrking upon metal. While as we note milling, lathe, and drill-press mechanisms answer our requirements in a highly satisfactory manner, it is not essential that we employ them all in one organization and it is equally apparent that we possible that oneattendant can in a single.

organized machine, look after 'several different operations. vIn the structure we have especially disclosed, Vsuch individualfcan simultaneously take care of in a unitary apparatus milling, lathe, and drill-press operations which is a highly advantageous consideration.

le deem it a matter of importance; to call attention to the fact, although we believe we have already made it clear,'that it is in no sense necessary for us in a unitary apparatus to provide milling, lathe, and drill press mechanisms, yet obviously theirV association is a highly advantageous one.. In the metal working machine of whatever its character may be, there is, as will be apparent, a plurality of metal working, desirably metal cutting, mechanisms, each capable of performingV a function different from another of said mechanisms, and each involving a work holder and a tool holder, at least one of the holders beingrotary, in connection with means by which the rotary holder of a mechanism may be put individually into action or by which a plurality of the mechanisms may be put concurrently into action. Usually the metal working mechanisms which perform these different functions involve each a work holder and a tool holder, one being rotary, in conjunction with means by which the rotary part of a mechanismv may be individually put into action,or by which the rotary parts of several of the mechanisms may be put concurrently into action.

From this, it will be of course clear that there may be instances where there may be only one such rotary part, although custon arily there are several; that is, two or more. Y The rotary part consists, not always, yet quite preferably, whether there be one or more of them in any organization, of a spindle.v There may be conjoined with one or more of suchspindles mechanism of a character entirely different from any of those to which I have specifically alluded.

A metal-working machine compris-V ing milling, lathe and drill-press mechanisms, the milling and the lathe mechanisms each involving a carriage and a spindle in correlation with each other and the drillpress mechanism involving a spindle, a source of power, the three mechanisms and the source of power being assembled into a single unit, and means operable by the attendant of said machine, for causing the simultaneous rotation of the three spindles and the movement of the two carriages, from said source of power.

41. A metal working machine comprisking a plurality of metal cutting mecha- Y volving a rotary spindle, and means common to the several mechanisms, by Vwhich said mechanisms may be individually put into a'ction'or by which the several mechanisms may be concurrently put into action,

the spindle rotating when the mechanism involving it is in action and also rotating when the several mechanisms are p concurrently in action.

43. A` metal working machine vcomprising a plurality of metal working mechanisms, each ca'pable'of performing a function different from another of said mechanisms, and each involving a work holder and a tool holder, at least one Vof the holders being rotary, and means common tothe several mechanisms, rby which the mechanism involving said rotary holder may vbe individually put into action or by which a plurality of the mechanisms may be concurrently put into action.

44.' A metalworking machine comprising a plurality of metal working mechanisms, eachcapable'of performing a Vfunction different from another of said mechanisms, atleast one of the mechanisms involviiig a holder which is rotary and has means for gripping a part, and means common to the several mechanisms by which the mechanism involvingsaid rotary holder may be individuallypput into action or Vby which a plurality of the mechanisms maybe concurrently put into action.

45. A metal working machine comprising a plurality of metalworking mechanisms, each capable of performing a functiondifferent from another of said mechanisms, atleast one of the mecha-nisms involving holders, one ofi which is rotary, one of the holders acting to .grip a tool and the other to grip a piece of work, and means common to the several mechanisms, l by whichtlie mechanism involving said 'holders may be put .individually into'actionduring which one of the holders'rotates, or. by

Ves

which a plurality of the mechanisms may be concurrently put into action.
