While there is illustrated in the drawings and
hereinafter described, a preferred form of the
invention, it is contemplated that various modifi
cations may be made by those skilled in the art
without departing from the spirit and scope of

extending upwardly from opposite sides of a
40 somewhat central portion of the bed, a crosshead
35 between the upper ends of the columns, a
cross rail 35 slidable vertically on the columns,
and tool supports 31, 38, 39 and 40 mounted on
the columns and cross rail. The bed 30, table 3l,
45 columns 33 and 34 and other parts of the planer
are preferably fabricated from standard metal

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.

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).

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

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

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

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

end of the feed cylinder |39 is preferablycon
nected continuously to a source of fluid >under
pressure which urges the piston |2| downwardly

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

site directions from the vertical splined shaft 5|.
Thus, as shown in Fig. 12, gear |81 is secured
to a beveled gear §33, rotatably supported on a
fixed shaftV | 3i. The gear |82'is carried on a bev

Vmeshes with the beveled gears |38 and |92.
As illustrated in Figs. 1 and 2,-thetool support
38 is provided with a swivel base 44 and agtool
slide 45, the same as the tool support Nillus
trated in detail in Fig. 2l.V The showing of the
swivel base, tool slide, etc., has been omitted in
Figs. 9~to 11 because they are duplicates of the
corresponding parts illustrated in Fig. 21. Thus,
in Fig. i() there is indicated only the shaft 55 and
attached beveled gear 54 of the gearing connec

To actuar@ the Vw01 slide asien the tool support

on theY tool support, 38 (Figs. 9 to' 1l). At'rthe

Figs.- 9 and 1G, there is» a beveled gear 20|,
meshing with the gear
Adjacent the right~
hand end of the shaft 280 is a pair of gears
4282'splined to and shiftable on the shaft. These
gears may be shifted into engagement with gear

shaft 280 in one direction or the other'. The
gears 282 are arranged to‘be shifted by means» of
a yoke 203 carried on a horizontally slidable rod
28e on which rack teeth 205i are formed.
A con
trol handle 288 is pivoted on ahorizontal pin 201
and carries a segmental gear ,288 meshing with
the rack teeth~205 to enable >thefdesired- shifting
