Means are provided for imparting com-. bined rotary and reciprocating movements to the table for imparting paths of movements to the table of various configurations,

whereby the work may be moved with relation to the tool along various lines, dependent upon the tool-position with relation to the axis of rotary movement of the table and the extent and speed of its recipro eating movements with relation to its speed ort rotation, the reciprocating movements taking place simultaneously with the rotary 11 is an arbor journaled in bearings 120i the base. i

13 is a gear loose on the arbor. 14 isa gear fast on the, arbor. 15 is ashaft journaled in a bearing 16 of the base. I 'It has a gear 17 fast thereon which, meshes with the gear 13.

7 1B is an arm which has a shaft 15,

bearing 19 about Patented Dec. 10, 1 912.

20 is a gear secured to shaft 15 and 21 is w an intermediate gear shown on a stud 22 on the arm between the gear 20 and the gear 14. Various relative speeds may be imparted between the gear 14 and the gear 13 which I have shown accomplished by changing'the ears 20, 21. The shaft 15 isremovable, as y releasing the nut 23, whereby the gear 20 may be changed, and the gear 21 is removable by removing the stud 22 and inserting it in a given hole 24 in the arm, of which two are shown and a number may be provided, or other speed changing means employed.

' nal-piece and pressing the gib 32 between 26 is a turning piece, shown as a journalpiece which is adjustable with relation to the gear 13 for placing the same for instance concentric therewith or at various degrees of eccentricity thereto. It has a slideway 27 therein engaging a guide 28 on the gear and arranged. to be clam ed to the gear by clamp-bolts 29 passing through slots 30' in the j ournal-piece and into the guide, or the same'may be clamped in adjusted positions by the clamp-screws 31 threaded in the'jourthe ournal-piece and guide.

33 is a mating piece for the turning-piece and is shown as a bearing-piece about the journahpiece 26, which follows the movements 'of said journal-piece when the latter is placed eccentric to the arbor 11. '34 is a table-guide. The table has a slideway 35 thereon coacting with the slideway 35 on the table-guide and is reci rocated thereon. The table-guide is secure to the arbor and rotates therewith. A rin 36 acts as a support for the ends of the tablecontact with the ring.

' the t'able, as by bein the bearing-piece.

As the arbor 11 turns the table-guide 34 which is ri idly secured thereto turns therewith.. Ift e train of gearing between the gear 14 and-the gear 13 is interrupted and the table is secured to the table-guide, as

by pins received in holes 44, the table will rotate with the'arbor. If the journaliece is .eccentrically located on the arbor? an the pins removed, and relative movement is imparted between the arbor and theta'ble, a

I reciprocating. movement in "the plane of the table will also beimparted to the table, and

the path of movement of the table and consequentlythework thereon, will the resultant of the two movements, namely rotaryand reciprocating, thus imparted 'to the table. When this relative movement takes place and the journal-piece 26- is eccentrically placed with relation tothe arbor, the

table will be reciprocated lengthwise of the table-guide 34, the direct-ions of recipro- I catin movement depending on the radial positions assumed by the tablerguide during ltsrotations. The movement of the bearingpiece along the guide-bars 39 is an idle movement, and the movement of the bearing-piece in directions crosswise of the guide-bars is a movement to efi'ect lateral reciprocations ofthe table.- The extent of these reciprocating movements is determined" i by the degree of eccentricity to which the I ournal-piece 26 has been adjusted, and number of lateral 'movementswith' relation" to the rotation of the table'is dependent on the relative speeds between thejarb'or and the journaLpiece. In practice, in my improved construction, the dlstance of rec1proeating travel of the table is four times the distance between the rotary axis of the arbor and the central axis of the eccentrically' rotation of the arbor, an elliptical path of" travel will be imparted to the table; if the relative speeds between the parts mentioned. is two to one, the path of travel ofthe table will be of general triangular form, and other forms may be. provided by variations of the relative speeds of the parts'mentioned'; The configuration of the out im arted will also be dependent on the coinci enoe'or lack of coincidence of the cutter with relation-to the axis of rotation'of the arbor.

'It is desirable that the table be positioned for causing its table-guide toextend in a fixed direct-ion when placing the gearing in operative relation so that its reciprocating movements may take place along predeter-' mined paths, and for accomplishing this I provide a stop-pin 46 arranged to engage an aperture 47 in the table, the stop-pin being mounted on a stand 48 adjustably held in a slot 49 in the frame, as by means of T-bolts 50 and nuts 51, the pin or stand or both being arranged to be sh'dout of range of movement of the table or to be taken off the 'frame if. desired.

' Incertain characters of work it is-desired to clamp. the table rigidly to the frame, for which purpose I provide a bracketstand 52 having a nose 53 received under a peri heral flange 54 of the table, a clampblocE 55 being received over the flange. The parts'are clamped together by T- olts 56 received in T-slots 57 in the-frame, an'dpassing through the bracket-stand and clamp-" block, and clamped in place by nuts 58. The

bracket-stand is shiftable lengthwise of the slots or may be removed from the frame if desired.

In my improved device provision is made for employing. a rotary or a stationary'tool, and performing the operative function under employment of the table while the latter is stationary and a rotary tool is emp-lo ed, or while the table is driven by power, fe by power, or fed or positioned by hand under employment of a rotary or a stationary tool.

65 is a power-shaft to which rotation is imparted by suitable means, as through the cone-pulley 66 in connection with which the back-gearing 67 'niayalso be employed for multiplying the speeds. Y

68 is a drive-shaft carrying a bevel-pinion 69 meshing with a bevel-gear 70 secured to the arbor 11, the drive-shaft being journaled ina bearing 71 in the frame.

The power-shaft has a gear :72 fast therei on which meshes with a gear 73 loose on the drive-shaft, the hub 7 t of which is journaled in a bearing 75 in the frame.

76 is a clutch between the drive-shaft and the gear 73 and has spline connection with the shaft, and is arranged to be operatively engaged with the gear-by an operating arm 77 which is secured to a rock-shaft 78 which has on it a fork 7 9 received in an annular groove 80 in the clutch. If it is desired'to drive the table, the clutch 76 is moved into operative position, whereby power is transmitted from the power-shaft to the table for driving the same with a fastmovement, for

instance when employing a stationary cutter, as in performing planing or shaping operations. Bythis means a piece of work may be planed or shaped in circular, elliptical or other desired shapes under employment of a stationary tool and-a rapidly movingtable, and threads may also be chased while rotating the work, insuring accuracy of threads. If it isdesired to move the table with a feeding movement, the feeding means for the table are brought into opera-.

tive relation. This feeding movement is imparted to the table for instance when performing a milling operation, when a rotating tool, for instance a milling cutter, is attached to the tool-spindle and the table is fed for advancing the work comparatively slowly along the path ofthe cutting itis' desired toperform, whether round, elliptical 'orother vdesired shape. The feeding movement is also employed when milling threads with a rotary cutter. Forfefiecting these feeding movements I have provided thearbor 11- with a worm -wheel 85, with which aworm SG-is adapted to mesh, the worm being shown moimted'on a slide 87 having bearings 88 for .the section 89 of the worm-shaftand .slidable in a bearing 91 of -the base.- 92is a rock-shaft journaled in 102 of the worm-shaft are connected by the section 105 thereof, there beingknucklejoints 106, 107 between the section 105 and the sections 89, 102 "respectively for permitting the lateral movement of the worm 86.

111 is a tumbler having bearings 112' about the tumblershaft, about which the tumbler is rockable, the tumbler carrying with it a shaft 114 journaled in bearings 115 thereon and'carrying a bevel-gear 116 in mesh with the bevel-gear 109, and a worm 117 arranged to be selectively engaged with any of the nest of worm-gears 101 for imparting various speeds of feed from the tumbler-shaft 108 to the worm-gearshaft. For imparting power rotation to thewormggar feed I provide the shaft 108 with a gear 122 is a rocker-plate swinging on a hearing 123aboutthe tumbler-shaft. 'It'hason I it a gear 124 in mesh with the gear 121 and adapted to engage a pinion 125 on the hub 74 of gear 73.

127 128 are gears on mesh with the gear 121 and the gear 128 bethe rocker p'late which rotate together, thegear 1'27being in ing arranged to be broughtinto mesh with the pinion 125. Either gear 124 or 128 may be brought into mesh with the pinion 125 for imparting selective speeds to that pinion or both said gears may be brought into neutral position for interrupting the train of power feed'to the shaft 108, the positions of the gears being determined by the swinging of the rocker-plate 122 by means of a handle 129 provided with'a lug 130 arranged to be selectively received innotches 131 of a positioning plate 132, for maintaining the gears in adjusted positions.

The tumbler 111 is provided f with a handle 136; It isreceived through an open ing 137 in the feed-box and is arranged to rest in notches 138, the handle bei-ng'provided with a pull-pin 139 selectively rec'eived in holes 140 forfloperative1y'engag-: .ing the worm 117 with ,axrvone ofwthe nest I v of worm gears 101, dependenton the speed 125 of feeding movement it is desired to impartto the table.

Rotary and axial movements mayalso be imparted to the spindle, and the cross-slide be moved. upon the cross-rail. For accomplishing these movements 176 is an upright'shaft arranged to berotated in reverse-dlrections-by means' of bevel-gears 177 178 gear 179 meshes.

180 is a clutch-sleeve having spline-conwith which a bevelclutches 182 183, either of which maybe rendered o erative for driving either bevelear 177 1 8 or both rendered inoperative or causing the upright shaft to remain at rest. The'clutch-sleeveis shifted by a fork 184 receivedin an annular groove 185 in the sleeve and mounted on a rocl r-shaft186, on which an operatin arm 187 issecured, po-

sitiond by a pul -pin 188 received in selective apertures 189 on the frame. The

bevel-gear 179 is secured toa shaft 190 joura recess 198 in the end of the hub of bevelgear 195 and ma bearing 199 on the crossmitting gears hereinafter mentioned for pc- "arranged to clutch 246.

sitioning the longitudinal axis of the spindle in upright position or at an angle thereto, the same being clamped in adjusted positions by clamp-bolts 203.

204 is a screw having a bore throu h which the reduced shank 205 of the spin le extends, being held longitudinally with relation thereto by a shoulder 206 and the positioning nuts 207. v v

208 is a nut received about the spindle screw 204 for moving the same longitudinally, the spindle-screw passing through a bearing 209 on the'housmg, with which it has splineconnection 210 for preventing turning of the screw. The spindle-nut has gears 211 212 fast thereon with which gears 213 214 mesh. The gear 213 is loose on a shaft 215 and the gear 214 is fast on a sleeve 216 received about said shaft. The shaft is journaled in bearings 217, and the sleeve in a bearing 218. A clutch sleeve 219 has spline-connection with the shaft. Clutches 2 20 221 arebetween the clutch-collar and the respective gears 213, 214, a fork 222 being received in an annular groove 223 of the collar and mounted on a rock-shaft 224 journaled in the housing and operated by an arm 225. for moving the collar into neutral 'position or for enga ement of either of the clutches, the arm ing suitably positioned.

The nest of gears 230 is in mesh with a nest of gears 241 -on a sleeve 242 received about a shaft 243 journaled in a bearing 244 of the housing, the sleeve having thereon a hand-Wheel 245, the sleeve and shaft being be secured" .together by a If it is desired fo-- "feed"the spindle by hand, the clutch 246 'lsreleased, permitting the hand-wheel and nests of gears to be turned for transmitting movement through a selective one of the nest of gears 230 to the upright shaft for feeding the spindle longitudinally by h-a nd. When. gear 213 is clutched to the shaft 215,- the nut is arranged for imparting comparatively rapid longitudinallyri by hand. When gear 213 stance for bori'ng.'""Whenthe clutch is engaged with the gear 214,,th'e nut is arran ed r imparting a slower 'longitudinal fee to the spindle, for chasing or cutti'ngthreads of a pitch determined by which of the nest of gears is clutched to its shaft, and which may be instanced as quarter inch threads, eighth inch threads, or pipe threads which are eleven and one half tov the inch. Under this arrangement the holes can be bored and the threads chased with a stationary tool or milled with a rotary tool under employment of a rotary movement of the table, and without resetting of the piece of work, and accuracy and alinement of the threaded holes assured, as firm relation of the moving parts can be obtained, which is often missing when tapping threads, and holes of large diameters may be threaded economically, as the provision" of large diameter taps, which are expensive, is avoided.

' The shaft 243 has a bevel-pinion 247 fast thereon which is meshed by a transmitting bevel-gear248 journaled loosely about the spindle and meshed by a bevel-pinion 249 on a shaft 250 which has a bevel-pinion 251 thereon meshed by ahevelar 252 on a sleeve 253rotating loosely a out the crossshaft 197 and having a gear 254 thereon meshed by a gear 255 on a sleeve 256 having spline-connection with a cross-shaft 257 parallel with the cross-shaft 197 and having a gear 258- fast thereon which is meshed by a gear 259 fast with relation to the bevelgear 195, whereby feeding motion is imparted to the spindle. The sleeves 253 256 are journaled in bearings of a connecting piece 260 on the saddle and slidable longitudinally of the cross-shaft.

261 is a clutch between the cross-shaft 197 1 I, and the bevel gear 195 for causing the crossshaft 197 to rotate, thereby transmitting driving movement to the spindle. The clutch 261 is operated by a handle 262.

263 is a bevel-gear which has spline-connection with the cross-shaft 197, the hub whereof is journaled in a bearing 264 on the saddle. The bevel-gear 263 meshes with a bevel-gear 265 on a sleeve 266 journaled in a bearing 267 in the saddle and also hav-- ing fast thereon the bevel-gear 268. The shaft 250 is journaled in the sleeve 266. The bevel-gear 268 meshes with a bevel-gear 269 whose hub is journaled in a bearing 270 'of the housing and which has spline-connection 271 with the spindle for rotatively driving the same.

For feeding the cross-slide len thwise of the cross-rail I provide a crosseed screw 275having threaded engagement with the saddle and a'ratchetrwheel 276 thereon.

277 is a double-tooth pawl, either of the teeth of which is arranged to be placed in operative engagement with the ratchetwheel, or the pawl may be placed in neutral position with relation thereto. The pawl is mounted on a rocker-arm 278 which swings about the cross-feed screw. A link 279 connects the rocker-arm with a crank-pin 280 on a crank-block 281 adjustable in a slot 282 of a crank-plate 283 secured to a shaft 284 journaled in 'a bearing 28,5 and having a gear 286 thereon which meshes with a gear 287 on the cross-shaft 257. By these means the screw may be turned in either direction or remain idle as desired. It has a'square end'288 for the reception of a hand-crank. v

For raising or lowering the cross-rail on the c0lumn,a screw-rod291 is journaled in a bearing 292 on the column and has threaded engagement in a nut 293 on the cross-rail. It has a gear 294 secured thereto.

295 is a rocker-plate having a bearing 296 about the screw-rod 291, the upright shaft 176,having a gear 297 thereon. On the plate there is a gear 298 and apair of gears 299 300. Either gear 298 or 300 is adapted to make engagement with the gear 297 for rotating the screw-rod in either direction for raising or lowering the crossrail, or the gears are placed in neutral posis tions, when the cross-rail remains at rest. The plate may be provided with a segmentgear 301 with which a segment-gear 302 meshes, the latter being on. a rock-shaft 303 operated by a handle 304, having a positioning-lug 305 thereon arranged to be received in suitable slots in a positioning-plate 306. Describing the operation of my invention as applied to one of the uses to which it may be put, and instancing that use as the machining of a locomotive dome, it ma be stated that a locomotive dome has an elliptically formed man-hole which it is neces-' sary to finish for the reception of the'manhole .cover, and the man hole cover must be finished to fit the man-hole in the dome, the man-hole cover being provided with a laterally extending flange received against the inner face of the wall of the man-hole, the cover closing the'hole from the inside of the dome. A

The man-hole in practice must-becut out of the solid steel shell of the dome. In practice this has heretofore been accomplished by drilling a series or gang of holes in an elliptical line surrounding the part of the dome which it has been desired to remove, then forcing out the part to be removed, and then chipping off the ridges left between the drill holes. The operation has been tedious and an accurate fit with the cover cannot be obtained thereby. With my improved device I place the dome-head on the table, set the table for an elliptical closed path of travel, insert an ordinary square-nose tool in the tool-head, and then connect up the power driving mechanism for rotating and reciprocating the table during rotation, for imparting an elliptical path of movement to the table, corresponding with the elliptical form for the man-hole it is desired to cut, the tool in the meantime being fed by the feeding action of the spindle. When this operatlon has been completed, a facing tool,

which projects under the wall of the elliptical hole just cut, is placed in the tool-head, the table driven as before, and the inner face of thewall of the man-hole finished for the reception of theman-hole cover. When this operation has been performed, a milling cutter may be inserted in the spindle, rotation imparted to it, the table-drive thrown into inoperative relation and the table-feed operatively connected with the table, for feeding the table in its predetermined path of movement slowly for operating in conjunction with the rapidly rotating milling cutter, the spindle drive also having meanwhile been thrown into operative relation, and in this manner the vertical wall of the man-hole may be finished. All these operationstake place without resetting the parts determining the path of movement of the table, insuring accuracy of movement and coincidence of movement when performing the various cutting operations. These domeheads also are provided with threaded openin s, one for the pop-valve, one for the sa ety-valve, one for the air-brake pipe, and for other purposes. These holes may be formed in manner similar to the formation of the elliptical man-hole, by shifting the position of the dome upon the table sons to bring the center of the hole above the axis of rotation of the table-arbor, or the same may be formed by clamping the table in stationary position and supporting the same upon the nose-block, having positioned the cross-slide andthe table selectively to bring the spindle into correct position for boring these holes, and after boring the same, applying a tapping attachment to the spindle for tapping the threads. The man-hole cover may be finished in similar manner to a true fit with the man-hole wall, without intermediate resetting of the parts determining table movement, insuring true matching in form between the engaging faces of the man-hole and its cover. The man-hole or thecover may be first finished.

With my improved device various forms of openings and covers therefor, or mating faces of various configurations on different parts may be accurately formed to fit each other, as readily as round openings and covers or parts received thereby have heretofore been formed on an ordinary boring mill. Other operations than those instanced may be performed by tion.
