are seated in a groove formed in the overhanging portion of the column base 31 at one side. of the machine as clearly shown in Fig. 3. These gibs 1'7 guidingly engage against vertical portions of the bed plate or base and the gibs 17, seev also Fig. 5, have-inclined portions 18 which are engaged by the wedge portions 19 of the wedge screws 20. Y Bolts 9, see' Fig, 1, extend through the overhanging portion 32 of the column base 31 and serve to draw and maintain the gibs 17 tightly against the wedge portions 19 of j the wedge screws 20. Each of the wedgescrews 20 has a stem 21 which receives a threaded cylindrical member or sleeve 22 revolubly thereon. The threaded sleeve 22 is hexagonally shaped as indicated at 23 in order that it may be rotated as desired and a ring 24 serves to maintain the sleeve member 22 upon the stem 21. See Fig. 6. A nut 25 serves to lock thewedge screw in its adjusted position. i

As shown'in Fig. 5 the column base 31 has a series of holes 26 extending upwardly from 1111- derneath one of its overhanging portions and these holes 26 are threaded to receive the members 22 at their lower portions and the upper tapered portion of the wedge screw extends up wardly back of; the longitudinally located gib 1'? whereby the same may be adjusted tightly against the outer face of the rib 12 on the bed plate. Anotherset of openingsf27 extend downwardly through the member 31 and receive similar wedge screws 20 which abut against the other gib 17 and thus render it adjustable to a position tightly adjacent the face 28 located in'the depressed groove 14 of the bed plate or basemember. The last mentioned set of ways and the gibs togetherwith their adjusting mechanism serve to prevent any movement of the column about the bed plate- In other words, referring to Fig. 8, any tendency of the column to twist in the direction indicated by the arrows B is resisted. It is to be noted that I provide adjustments for the longitudinally located gibs on'either side of the bed plate thus permitting the shifting of the bed plate laterally if desired in order that proper adjustment may be had by the wedge shaped gibs 13- and their supporting members 32.

Referring now to Figs; 8 and 9, characters A'? and B indicate arrows which show the several directions of movement which might be caused by theengagement of the tool 72 with the work. In Fig. 9, for example, the tool might be placed under a pressure whichwould tend to lift it or lower it and, as previously described, .the gibs 13 tend to prevent this movement between the column and the bed plate. Similarly, referring toFig. 8, the tool might tend to move the column as indicated by the arrows B and, as also previously set forth, the. gibs 17 prevent this The gib holder supports 15 gibs 17, see Figs. 3 and 1, and similar gibs 1'7 movem'ent. However, the reciprocating shaper bar 70 is mounted upon the apron which must also transmit the several forces which have just been set forth.

As shown diagrammatically in Fig. 8 the column 30 has ways or guides '75, '76 and '77, the ways being engaged similarly to the engagement between the column and the bed plate. Hence, without entering into detail as regards this construction, sufiice it to say, that this guiding connection between the saddle and the column is. substantially identical with the guiding arrangement between the column and the bed plate. However, as shown in Fig. 9, the rear way is made considerably shorter than the other .two ways as this way or guide, together with its gib, tends to prevent movement of the reciprocating ram in a horizontal plane, as indicated by the arrows,B" in Fig. 8, and hence no reason obtains why it would be of any great length. In other words the guiding means 75and 76 prevent the turning of the ram in the direction of the arrows A, see'Fig. 9, while the guiding means and '77 prevent the movement of theram in a horizontal plane.

The weight relief consists of a carriage or frame member having a series of. rollers 86 revolubly mountedv therein, these rollers traversing the track 87 rigid with the bed plate 10. A series of cups 88, see Figs. 4 and 7, receive springs89 and bolts 60 are threaded through the base of the column and abut against plates 61 which in turn bearlagainst the springs 89; Hence by tightening the bolts 60 the springs 89 are compressed to the desired degree-thus tend to lift the column member and all of its appurtenances 01! of the bed plate. Thus the friction between the base plate 31 of the column and the upper-surfaces 11 of the bed plate 10 is lessened so that the column may be easily reciprocated back and forth as desired. The springs are arranged in opposed relation so thattheir adjustment will govern the degree of bearing of either side of the column upon that particular side of the base, thus giving equal pressure at all points therebetween. l

Having thus revealed this invention I claim as new and desire to secure the following combination and elements or equivalents thereof, by Letters Patentof the UnitedStates;

1. In a device of the class described, a member having ways thereon, a second member slidably mounted upon said ways, gibs located onthe second. member in parallelismto the direction of movement of the two members, said first member having surfaces at right angles to the surface of contact between theutwo slidably mounted members," said surfaces adapted to be engaged by the said gibs, said first member having an-. other set of surfaces parallel to the direction of movement of the two members and at right angles to the previously mentioned surfaces on the first member, gibs on the second member adapted to slidably engage thelast mentioned 'set of surfaces; said last mentioned surfaces with their contacting gibs being spaced farther apart laterally than the other two gibs and their respective surfaces.

2. A device of the class set forthin claim 1 in which three of the fourv gibs have means for adjusting them withrespect to their contacting surfaces. 1 I

3.-In ametal planing machine, a base having a surface on which a column rests in part, a truck or carriage running on the base and supporting its means whereby it may be separately compressed as described.

5. In a traveling head shaper having a bed plate with ribs extending laterally therefrom, a column having a base portion slidably mounted upon the bed plate, said base portion having overhanging parts extending underneath the ribs, gibs located between the bottom face of either rib and the overhanging parts, another gib located between the side face of one of the ribs and the adjacent overhanging part whereby sidewise movement of the column in one direction is.prevented, and means to prevent sidewise movement of the column in the opposite direction, both of the means for preventing sidewise movement of the column with reference to the bed plate being adjustable whereby the column may be bodily shifted sidewise.

6. A device as set forth in claim ,1 in which one of the gibs in each set is adjustable for the purpose described.

7. In a metal planing machine having a bed plate or base adapted to slidably receive a column thereon, the combination of ribs or shouldered portions extending from one of the slidably associated previously mentioned elements, overhanging portions on the other previously mens tioned element, said shouldered portions having parallel ways engaged by the overhanging portions to prevent separation of the two elements, one of said shouldered portions having a way at right angles to the previously mentioned way formed thereon, means on the opposed overhanging portion engaging against the last mentioned way whereby lateral movement between the two elements in one direction is prevented and additional means between the two elements to prevent lateral movement in the opposite direction, said additional means including a groove formed in one of the elements, a gib contacting against one side of the groove and means to fasten the gib to the other element.
