67, Fig. 10, a change-gear removably secured to the'outer end of main feed-shaft 37; 68,21.

change-pinion removabl y secured on the hub of pulley 34 and adapted when eccentric stud i 33 is properly adjusted to mesh with gear 67, gear 67 and pinion 68 being interchangeable,

' the work-table,wherehy the longitudinal feedvan tageons manner, as will be obvious,

ing motion of the work-table through the turntable is arrested at desired point by the operation ofa dog on the work-table; 71, Fig. 4 only, a vertical saddle adapted to interchange with vertical saddle 7 and take the place of the latter upon the column of the machine when vertical milling is to be done, saddie 71 being provided with a rigid integral arm projecting out over the work-table; 72, a vertical spindle journaled in. the outer end of the arm of saddle 7'1; 7 3, bevel-gearing counecting saddle-spindle 8 with vertical spindle 72, and 74 a vertical mill secured at the lower end of spindle 72.

The main description has been giveuupon the machine as adapted for horizontal milling. For vertical milling the saddle 71 displaces the saddle 7,t-he two being interchangeable upon the column.

The thrusts due to the strains of cuttingare met by the rigid members and sliding surfaces of this machine in a particularly-ad- Bed 1 may be ofany length desired without in any a degree im pairing its capacity for resisting the cuttingstrains. Outboard-column 15 may be adjusted at any desired point along the bed,

, and it may be employedor dispensed with,ac-

cording to the requirements of the work. Its

bearing 16 may be employed. in supporting steady-bar 11, or it may be lowered into line with spindle 8 and serve as the direct ontboard-bearing for an arbor or boringbar. Steady-bar 11 may be employed in furnishing the outboamlmearing for an arbor or a boring-bar, either alone or ,in conjunction with out board-column l5and its bearing lfi. Either oi the eyes 12 and 13' may be swung into the proper line for use, it thus being practicable to have a large bearing-eye-for large arbor-s,

&c. and a small one for small arbors or fora center. r

Turning to Figs; 5 and 8, it will be obvious that belt 36 is maintained at constant tension throughout the vertical adjustmeutofsaddle driven at the speed of pulley 18, but with locking-pin 21 disengaged and the back-gears brought into action then spindle 8 turns very much slower and more powerfully.

Turning to Fig. 9, it will be obvious that change in feeding rates.

vertical saddle 7 may adjusted on its column by hand-crank on shaft 54, operated conalso be obvious from Fig. 9 that all of the power feeding motions are derived from main feed shaft 37, taking its mot-ion through change- gears 67 and 68, Fig. 10, the intercha'ngeability of which provides foru radical Manipulation of handle 35 disengages gears GTwrdfiSaud instantlyarrests all the power feeding motions The'vertical adjustment of the bush-wheel obviously provides for grad nations of rate of all of the power-feeds and fora change in direction of all of the power-feeds. The direction and rate of feed can be readily judged from the exterior index, and the rate and direction of feed can be readily changed by crank on shaft 45 while theinachine is in motion.

- Bush-wheel shaft 39 gives motion'to splined ,shaft 47, and by throwing clutch 58 into engagement with gear 5; feed mot-ion may be imparted to screw 51 and to the horizontal saddle at rate and in direction depending on the adjustmentof the bush-wheel. By throw- I ing clutch 58 into engagementwith gear-56 feed motion is similarly imparted to screw 60- and the vertical saddle. The feed motion of the horizontal saddle is tripped by the action of tappet 63 on the dogs 64 of the horizontal trip-rod, the result being the throwing of clutch 58 to idle position. Similarly the feedingmotion of the vertical saddle is tripped by the action of the dogs on vertical trip-rod 65, which through rod 62 releases the clutch. The work-table is traversed through the turntable by screw 69 and tripped by trip mechanism 70, as usual.

Referring to Fig. 10, it maybe stated that rt-is preferable to form mainfeed-shaft 37 in so as togzmaintainl proper frictional contact between the bush-wheel and the disk which drives it, such adjustment being usual in bush-wheel devices.
