The cross rail 36 may be adjusted vertically on 2,412,355? 4 3 in the opposite ends of the cross rail. The screws ' ¿i2 and 43 are arranged to be actuated simulta neously at feed or traverse speeds by means of mechanism illustrated partly in Figs, 13 to 20, `and. hereinafter described in' more detail. These screws may valso be disengaged from the feed traverse mechanism and then serve as stationary lead screws for actuating the `tool supports 31 and = 38, as hereinafter described. , As shown, the nut is formed integrally with a gear |69 which meshes with a gear |58, splined the columns 33 and 31| by means of vertical screws 42 and ¿i3 which engage suitable nuts (not shown) on the shaft 48. The gear |58 is conñned be tween opposed portions of the bracket |59 so as to move with the support 39. Thus, the connec tion between the shaft ¿i3 and the feed screw |51 is similar to that shown in Fig'ä for the tool sup port e9. 11g) The means for> actuating the tool supports 39 and 39 will be described ñrst. The tool supports 39 and 46» areslidable trans'- ' versely of the planer table as Viewed in Fig. 1` (simultaneously or independently) and at fee and traverse rates. Furthermore, the tool sup ports carry swivel bases (el (Figs. 1 andv 21) on which are mounted tool slides 45 which are movable diametrically of the swivel bases, simul taneously or independently, and at feed and traverse speeds. The means for actuating the `tool supports‘and tool holders includes splined shafts 41' and 45 (for-'the support 59 and its slide 45, respectively) and‘splined shafts 48 and :i9 (for the support 39 and its slide ~ ¿35, respectively). ` These Vsplined shafts are> arranged to be'dîri‘venl at feed and traverse speeds by a.Ífeed'-traverse mechanism designated generally 59 (Figs. 1, 2 and 13), a` vertical splined shaft'5í, and gearing des- ‘ ignated generally 52 (Figs. 1 to 3). Y _ The' connections from thesplined shaft 46 to the tool slide 45 on the support liîlare'shown in Figs. 21 and 22. A gear 53 is splined to the shaft 4t and' is confined in a bracket |59, v,carried on support 43, Vto move laterally with thatlsupDOrt. A gear |5| meshes with gear .53 and’is rotatably The tool slide £5 on the tool support 39 (Fig, 1) is arranged to be actuated by screw and nut mechanism similar to that shown in Fig. 21 on the tool support d0. The connections from the beveled gear 53 on the short shaft 55 are slightly different, because the axis of the shaft 55 for the ` toolsupport 319`r is in the same horizontal plane as that for the tool support 49. Thus, as shown in Figs. 2'3y and 24, thebeveled gear 54 meshes with a. beveled gear |52, which is rotatably mounted in a bracket |53 carried on the support 39 in a position concentric with- the shaft lll, Agearr |54 is formed' integrally with'bevele'd gear` |62, and _ meshes with an- idler gear |65, rotatably mounted , on therbracket ` |53 in a position concentric v.with thershaft 48. A thirdgear |56 meshes with gear |55; is-rotatably mounted on the bracket |63, and isy splined to the shaftßël. Thus, the shaft 4`9`is operable through an intervening gearing to- actue ate the tool slide 55 carried on the tool support 39. It is to be noted that there are no disconnectable clutches or other devicesintermediate the splined Shafts 95, t?, L39 andV 5.9, andthe tool supports and slides which they areconnected to actuate. Furthermore, as hereinafterY set forth, the four parallel splined shafts inY the vcross railall de t rive their power frornthe vertical splined shaft 5i. A meansßfor selectively connecting theïhori Zontal splined shafts 53 to ¿5to the vertical , splined shaft 5i» for simultaneous or independent " actuation of the toolfsupports and‘slides is joom prised in the gearing 52 (Figs, l Vto 4l)` whichV ‘ 1 which meshes with' a beveled gear 54 on a, short 40 mounted on bracket |59, concentric with shaft" M.

The screw 59 isrotatably supported at its ends on the tool slide 45 in : bearings Eiland 6_9', and‘engages a non-rotatable nut`6| supportedïon the swivel base 44’. A hand wheelV 52 is provided for adjusting the tool slide v manually. Thus, the tool slide d5 on the'sup , portiêil'rmay be‘actuated in a direction radially i ,ofits swivel base eli by operation of the splined gearingwillfnow be described. ' - ’ As illustrated herein, Vthe splined shafts of the cross rail are rotatably ijnounted'l inv and extend` through the ends 'i9 and ‘it of the crossrail to terminate in. squared! ends as'shown in'Figs. 1 and 4: The shaftsareparallel to each other butare arranged along the arc of a circle, as shown in’ Figs. 2. andv 3. Pairs of? pinions l2l are splined to the shafts and are shiftableïto-the right Vand left from the neutral positionsv shown in Figs. 4 and 6 to 8, so as to be engageable with either of large. gears 7_3 and. 73. These gears are rotatably ,. supported onjthe cross rail and, as shown ybest in Fig.vv 7., carry! beveled gears 'l5 and 'i5-,fixed ' For> moving the support~ liëplaterally on the thereon, which mesh with a common pinion?! cross rail 36, the splined shaftîë'î (Figs. 5, 21_and ` 55 which i's rotatably supported on thercross rail'ñand ` ¿g2-_2) Y-carriesa gear Y|53 splined thereon and con is splined to the shaft 5|.

The splined shaft 5| is arranged to be rotated at feed speeds, but in a single direction, in View of thel reversing devices incorporated in the gearing 52. For convenience, the shaft 5| is arranged to and I |3, respectively. These overrunning clutches may be of a form welll known in the art, adapted to transmit power in one direction of rotation and to overrun without transmitting power in the opposite direction. The clutches are arranged so that when the racks H6, H1 move upwardly be driven in forward and reverse directions at a traverse speed, by reversing the traverse motor 10 (Fig. 14), the clutch |26 functions to drive the hereinafter described. The actuation of shaft 5I at feed and traverse rates is accomplished by the feed-traverse mechanism 50 (Figs. 1, 2 and 13 to 20). Referring now to Figs. 13 and 15, the feed 15 shaft H2 while the clutch |21 overruns idly on the shaft H3. When the racks H6, H1 move downwardly, clutch |21 functions to drive the shaft 99, and at the same rate of speed (the gear sets 93, 94 and 96, 9T being of the same ratio) for handles |34 on their upper ends. It is contemplated that the table of the ma chine will be reciprocated by fluid under pressure operating on piston and cylinder devices, one for moving the table in a forward direction and the other for moving the table in a return direction, shaft H3 and clutch |26 overruns idly. Thus, the shaft 90 is driven intermittently in a single traverse mechanism includes a horizontal shaft direction of rotation, but alternately, by the gears 90 -extending from the mechanism 59 (Fig. 1), H0 and Hl. through the bed 3i! o-f the machine, through a To provide for fewer feed movements of the casing 9| and into a casing 92. A beveled gear 93 shaft 39 for each up and down movement of the on the left-hand end of the shaft meshes with a 20 piston |2|, means is provided for disengaging gear 94 on the lower end of a vertical splined shaft the pinions H4 and H5 from their associated _95. As shown in Fig. 13, a beveled gear 96, splined racks H6 and Hl. As shown best in Figs. 15 to and screwed onto shaft 39 adjacent the right 1'7, the pinions H4 and H5 are provided with hand end thereof, meshes with a gear 91 on the yoke grooves |39 which are engageable by yokes lower end of splined shaft 5|. Thus, the splined 25 |3| carried on arms |32. These arms are se shafts 5| and 95 are driven simultaneously by the cured to pivot pins |33 which carry operating~ a purpose hereinafter more fully described in con nection with the tool supports 37 and 38. . The shaft 99 is arranged to be driven at a rela tively high or traverse speed by means of a traverse gear lill] (Fig. 13), which is loose thereon, and a jaw type traverse clutch I0 | , |92 which is engage» able to drive the shaft 96 from gear Hill. The jaws of this clutch are herein shown formed on the gears 96 and |99. The gear |99 may be driven at a constant speed by an electric motor 392 (Figs. 1 and 18) by means of a pinion 392’ on the motor shaft and a wide idler gear 392” as disclosed in said copending application Serial v No. 512,154, filed November 29, 1943. The upper end of the feed cylinder |39 is preferablycon nected continuously to a source of fluid >under pressure which urges the piston |2| downwardly therein. At the end of the forward movement of the table, fluid under like pressure is admitted to the lower end of the cylinder |98. Since the meshing with the pinion and with the traverse area of the lower end of piston |2| is approxi gear IEíl. _ mately double the area of the upper end of the Shaft 99 is arranged to be given an intermittent piston, the piston is thus moved upwardly by a and relatively slow feed movement by means in- l differential action at the end of each forward cluding a jaw type feed clutch |93, |54 (Figs. 13, 15 415 stroke of the table. This pressure o-n the lower and 19) the element |93 of which is splined to end of the piston is maintained during the re and slidable on the shaft 9i), and is urged to» the turn stroke, at the end of which it is removed, right (Fig. 13) by a coiled spring |95. The clutch permitting the fluid under pressure on the upper element ||l4`is formed integrally with a spur gear |99 which is rotatable on the shaft 99 and held , between a collar |97 and a hollow hub | U8 formed on a cylinder |99. The gear |06 meshes with a pair of larger gears H9, Hi (Figs. 14 and 15) which, in turn, are mounted on shafts H2, H3, respectively, by means of overrunning clutch de- , vices |25 and |21. Pinions H4, H5, fixed on said shafts, respectively, engage racks H5, H‘l which are slidable vertically on opposite sides of the cylinder |09 in guideways HB', H1’. At their end of the piston to return it downwardly. Thus, the feed cylinder will be actuated at each end of the table movement. This arrangement is de sirable when the planer is set up with reversible tool holders (as illustrated in Figs. 1 and 2) hav ing forward and return stroke cutting tools 4|. If the machine is set up with tools arranged to cut only when the table moves in a forward di rection, the pinion H4 (vor the pinion H5, as the case may be) can be disengaged from its actuating rack by means of the appropriate handle |34, upper ends, the racks are secured to a crosshead (il) so that the shaft 99 (assuming the feed clutch H8 by means including screws H9.
