. If the machine had `four columns-or, if the column `I, were to extend above the table or face plate, a piece of machinery, which wouldreadily turn between the columns on the "face plate when arrangedl on it, could not" bejpassed through between said columns, the capacityfoffthe machine would be there'- `forerestricted to thespace` betweenv the e, y columns, 'and not to the diameter ofthe face It is actually necessary to firmly support e the`machine, as the least. springingor yield- .ing of the machine,` will make inaccurate work; Four columns, `thereforewas an under A bearing, appears to be necessary, and -three above `the table, to support the variusparts of the" machine. A single column` above the table is out of-the question, as the` part sup`- porting the",manclrel, tool stockfor upper spindle would have'to project so far, as to be iniirmly supported` unless by going'fon theother extreme,` it is made so heavy as4 fto be an incumbrance to itself. My machlne is therefore a four column" machine regards strength, and a three column machine, introducing work onthe face plate. a The shaft which supports the face plate E, `immediately underneath the face `plate passes through, and is supported in a hub J, which is firmly held in position by arms K, connected therewith, and to the` columns I, GL The faceplate is provided ywith any Asuitable number of radial slots L, in which are placed the dogs M, for chucking upthe pieces to be turned, bored or slotted.`

` A substantial curved iron plate N, having i its two ends secured to the columns G,

passes in rear of the machine, to afford a base and support for the driving machinery, and the plate N, is further supported by being connected to the rear, as well as the side columns G.

A shaft O, supported in suitable bearings on the plate N, has upon its rear end first a small gear wheel P, neXt a series of graduated pulleys Q-neXt a larger gear wheel R, and lastly a pulley S, around which passes an endless band T, for driving the upper parts of the machine, as will be described. The inner end of the shaft O, has upon it a clutch U, and at its extreme inner end a bevel pinion V, which works into the circular rack underneath the table or face plate E to give it mot-ion. When however the table is to remain stationary, the clutch U is moved back on the shaft. Underneath the eXtreme rear end of the shaft is hung upon a shaft W eccentrically supported in the hangers X, two cog wheels Y, Z, the larger one Y, meshing with the small one P, on the shaft O, when the shaft is turned by handle A' for that purpose, and the smaller one Z, taking into the larger one R, on the shaft O, by turning the shaft W, in a contrary direction; this being for the purpose varying the speed with which the table or face plate may be turned.

The rear column G, has secured upon its cap B', a forked column C' (a rear view of which is shown separate, to the left of its position in the machine (Fig. 1,) and on top of this column C', is supported one end of a shaft D', which is parallel with that O., heretofore described. From the tops or caps of the side columns Gr, springs an arch piece E', which beside its arched form from column to column, projects forward as Seen in Figs. 2, 4, for the purpose of bringing the center of the boring or turning stock which is supported in it, directly over the line of centers of the face plate and its supports.

The object of setting the side columns G, back of the line of centers has heretofore been stated viz: to afford an unobstructed front so that pieces, of such size as the face `plate will carry after they are placed therepiece rise the forks of a single (or two col-- umns) I', and in its top is support-ed the other end of the shaft D'. The endless belt T, from the first mover,passes over a fast pulley on the shaft D', when the tool stock is to be rotated, or shifted to the loose one J', alongside vof it, when otherwise. Underneath the shaft D', is a shaft K', supported in the crotch or forked parts of the columns C', I', and on it are placed the pullies L' and M', and between said pullies a double clutch N', operated by a shipper O', so as to throw it into or out of gear with either of the pullies L' M', which are of themselves loose on their shaft, while the clutch is feathered on the shaft in a manner well known to machinists. On the end of the shaft D', is a bevel gear P' which takes into a larger bevel wheel Q', on the top of or near the top of the spindle R'. This bevel wheel Q', is also feathered on the spindle so that the spindle may rise and fall while the vessel wheel always rotates in the same place, it being supported by the arm S', project-ing forward from the column I'. On the shaft K', at its inner end is placed a bevel wheel T', which takes into a bevel ygear U', on a sleeve or collar V', which passes through the hub G', and may turn therein, so that the spindle which may carry a boring tool on its lower end may be boring out the hub of a car wheel or crank, while the sleeve or socket outside of it, but also rotating may be carrying a turning tool, and be facing off said crank or car wheel at the same time, and when these two operations are going on the table may remain stationary, by simply throwing out the clutch U. But either the boring, or the turning, may cease without in the least incommoding the other which may go on, or both the turning and boring tools may be fixed, or immovable while the table or face plate may be rotated, whichever is found most convenient.

It sometimes happens that a crank, or other piece of machinery, will not turn around between the columns, in such case the tafble remains stationary and the tools rotate.l With other kinds of machinery the contrary may be required, and the machine is adaptable to either.1

On the spindle R', below the hub Gr', is attached a tool stock W', which rotates with the spindle when turned. A screw shaft passes horizontally through this tool stock, or rather arm, and has upon its outer end a star wheel X', and upon this screw rod or shaft is a tool holder Y', containing a cutting or turning tool Z'. As the arm W', sweeps around, the star wheel strikes against a trigger a suspended from the arch piece F' (and seen in red lines), which gives said star wheel and its screw shaft a partial rotation, which in turn causes the tool holder and tool to move slowly from the spindle toward the eXtreme end of the arm. This enables me while boring out a i i Z, is a handwheel on "ing theyslidebykhand. The cross head b, is

` raised `or lowered aslfollows: `so asto adapt .y to the piece'to bei worked. A horizontal shaft "m, (Fig.-2)jha`s upon one ofits eX- treme endsfa handywheel "ny and near each of its ends a` small bevel-*gear 0, which take into `bevel gears" p,\on `the-,upper `ends of rods-#the lower ends-i of "which are secured "lin `the said cross head, `thus by turning the hand wheel n, the cross head is raised i orlowered at pleasure.` Bythisl arrangement I face off-work that rotateswith the aeaaafpiacea @a upland down on the :side columns G, asf will in whichthe tool e, is held,

and said stock and tool are raised or lowered in the" slidingpiece c, byahand wheel f;

Thebevel `gear U",

i i a, is a shipper for throwing the beltiT,

I `have thus far shown how boring `or .l turning of various kindslnay be done, either Y "when the table orface platerevolves, or

when "it is stationary @and theftools rotate,

" and it` only `remainstof` describe how a key seat is cutfbefor'e "unchucking lthe piece.

"To giye""particularsof 4each and every :Vpart would make the @specification pro-11X, i and` describingthe main parts, I leavethe Q E; rases others as they are fullyshown in the 'drawings andI refer more especially to the bushspindle of the table. v

I have .i heretofore called V', Fig. 3, a sleeve,it` `is really a long tube, hollow so vthat the spindle R( may pass `through it,

and having a screwthread cut upon it, into which a similar threadin the nut which carries the bevel gear U, and wormg, works. The spindle R', may turn independently of the screw tube or sleeve, but when boring or turning the inside of a hub, the spindle is fed down by the worm and worm wheel before described. When a key seat is to be cut the bevel gearing P", Q', are thrown out of operation, and those T', U', into gear-the worm and worm wheel being' also` disengaged. Then by` driving the Y `shaft K, with the clutch N, in gear withv either of the pulleys L or M, as the case nlnay be, the nutv on which the bevel wheel U is arranged, by running in the screw on the hollow tube V, gives said tube, and the spindle R', with its cutting tool, a vertical rnotion, and thus the key seat may be chipped or cut outthe*table and the piece being' operated on it remaining stationary. i It will thus be seen the machine is adaptable to the turning, boring, facing, or drilling of heavy pieces of machinery, and also for cuttin the key seats, vand this too, vwhether the character of the work, or its peculiar shape besuch, as to require it to `be rotated, or whether it must remain stationary and the tools be operated, or portions `of either.A The turning may be done on the inside of the hub, on the face, or on the outside of the hub as for instance in a crank, with equal facility., And as it is suceptible of all these various adaptations, it avoids `the necessity of several separate `machines for doing the saine thing,and as a shop machine for various kinds of work is Jhighly valuable and useful.

' Having thus fully described the nature of my invention I would state that, I am aware that single column machines for bor-` ing and drilling small work have been used, in which the operative parts project forward of said column, this I do not claim as the support is not firm enough for accurate work of the kind which my machine is devised for and these I do not claim, but

i `What I do claim'as new and desire l,to Secure by Letters Patent is` 1. So` arranging vthe table or vface plate, and upper` spindle or tool holder, on a machine for turning,`lboring, and cutting keyseats, as `that either one ofthe two may be revolved, and the other remain sta-tionary,

`and substantially in themanner set forth.

i 2. I also claim combining with the upper spindle, a revolving slide head carrying la ings in the table and for supporting the as the" character of .the work may require,

cutter susceptible of either a horizontal or of the operative parts of the machine, for vertical motion or adjustment as set forth, the purpose of leaving an unobstructed front 10 for the purpose of turning oi Work either for the introduction of the piece to be inside or outside thatwili not revolve bedressed7 as described,
