Itis-desired'to produce a jointer having an exceedingly longtable surface as, compared to :g-thOSB presently in use. This requires an over-all table length of, the order of eighty inches, and due to the greater length and theoverhang relative to the supporting standard, the weight must be kept as low as possible and factors causing misalignment of one section of'the table relative to the other, must be coped with, and in addition, thejcost of'the structure must be kept low in view of competitive conditions. j An object is, there- .-fore,- to produce jointers having tablesupporting bed structures; which satisfy these requirements. For purposes of illustration but not of-limita- 5131011; an embodiment of the inventionis shown ,the accompanying drawings, inwhich I r i-Figurel is a side elevation-of a jointer, a portion of the supporting standard being broken "away; o I a a; Figure 2 is a top plan view of the jointer shown in Figure 1; Figure 3 is a side table supporting bed;

Suitably carried by the stationary bed A .isa. rotary cutter C driven by an electric motor Mounted ior "bodily shifting movements transversely ofthe table surface is a fence F, .,whi-ch"has a handle H and is. provided atone end ..wi th.a depending guide member F, which is se- {cured in. its adjusted position by. a locking device L.' Since the detailconstruction of the locking device and thejointerforms no .part of themes- Lent invention, further description and, illustration jthereo'f is notc'onsidered necessaryg,

Mounted-on the' table is a suitablevguard G which; protects the operator from the rotarycut- .ter Cand bears late'rally againsta. face of a work I L piece .,W; the other side; of which abuts against Qthe. fence F1 as willbe readily understood.

The stationary table supporting bed Avcom- .1.p'ri 'ses.a pair of laterally spaced, upright, parallel, longitudinal sheetmetalside plates [.0 and II, I the lower edge .portions of which are bent in- .wardly at substantially rightfangles to provide 'flanges.'l2,'which extend fromvone end to the lotherg. As. shown in Figure 3, the lower left-hand iend oi" the'- side" plates 10 are inclined, asindi- I catedfiat l3, whereas the remainderof the lower 40 edge portions, as. indicated'eat M, are fiat to be supported by the supporting standard S. Approximately-midway of the bed is a crosspiece I5,'the central portion l6, of which is arched up- .wardlylinia position between the side plates. .The cross. piece I5 is welded to the side walls and portions thereof extend beyond the opposite sides of th'ejside fwalls, theseportions being apertured to receive 'stud bolts or the like'for securing the bed to theLsupportingstandard. As shown at the '50 egtremeright-hand end of Figure 3, a similar jcross iece-ill connects the side plates I0 and H an d isjwelded in place, the cross piece I1 having a central aperture tdreceive a stud bolt or the like I I for securing theend portion of the bed 'to'the 55.'- u t: 1'

end of these incurred edge portions.

A major portion of the upper edge of the side plates l and H is flat as indicated in Figure 3 and resting thereon is a longitudinal sheet metal plate l8, which provides a table top for the bed A. The right-hand end of the table thereby extends slightly beyond a cut-out portion I9 and to the outer side of each of the plates l0 and H is welded an arcuate bearing pad to which bearing elements 2| (Figure l) are bolted. At the right-hand end of the bearing pads 20 (Figure 3), the upper edge portions of the side plates incline downwardly as indicated at 22. It is along the edge portions 22 that the adjustable bed rides as will hereinafter appear.

Beneath the table l8 and for reenforcing and supporting the side plates 10 and in upright position are transversely arranged sheet'metal spacer plates 23, 24 and 25, which arewelded in position. Near the left-hand end of the assembly is a flanged plate 26 which is welded to the a side plate flanges 12 .and the side "plates'ior reenforcing purposes. It will be apparent that the left-hand .end (Figure 3) of the bed A is open and insertable therein may be a drawer (notshown), which is suspended from giiideplates 21 depending from the under side of the table l8. v

p In the fabrication of the bed 'A, two 'subas'semblies are w'eldedto the right-handendportion (Figurelil to provide thefgibs, onwhich the adjustablebedBisishifted as well as to space and reenfo'rce that portion of thebed. These'two subassemblies are similar to each other and differ only in the length of the transverse plates. As

shown on Figure 8, each subassemblyconiprises a pairof spaced transversely arranged plates 28 and 29, each of which has a pair of upwardiyprojecting integral extensions 30 formed by cutting outan intermediate portion of the plate indicated atf3'l To the upper ends of corresponding extensions 36 of the plates 28 and29 are'welded gibs [32. The plate 29 extends upwardlybeyondthe I plate 28 as shown in Figure'3, thereby to "effect proper spacing and reenforcing. It will be understood that the suba'ssembly is first inade up and then introduced between the'side plates, the gibs inclining downwardly slightly below'thelinclihed edge. portion 22 an'dparallel thereto.

, It will be observedthatone subassembly is arranged adjacent the upper 'end or the inclined edge portions 22 and the other 'a'djacentthe'lower particularly in Figure 6, the'inner edge portions "of the gibs32 are inclined'rearwardly, the inner edge being approximately flush with theouter .edge of the respective extension 30.

Intermediate the two subasse'mblies above described'is a s'ubst'antially inverted U-shaped flanged plate 33,

which is spaced. farther below the inclined edge portions 22. This plate is welded to the inner ffacesof the longitudinal side plates l0 and II and is formed with a central hole 34 for apur'pose v hereinafter to be described.

The adjustable table supporting bed B is simi- Jlarly constructed of'sheet metal and has a table top 35 to the under side 'OflWhlCh are wel'ded a pair of longitudinally extending, laterallyspaced,

parallel sheet metal plates 36 and 31. Therighthand DOItiOn (Figures 9 a d 10) 0f the side plates inclines downwardly, as indicated at 3 8, and this portion of each of the side plates'has inwardly extending longitudinal flanges 39. A transverselyarranged sheet metal spacer and reenforcing .plate 40 is arranged between the longitudinal .plates 36 and 31 and is welded in lace.

Closing the outer end of the bed B is a steel.

As shown casting having a vertically disposed, longitudinally slotted plate 42, which extends laterally to one side of the table and carries a table extension 4! on its upper portion. The longitudinal plate 3! abuts against the rear face of the plate 42 to which it is welded and the longitudinal plate 36 overlaps the other end of the'plate 42 andis likewise welded to it. A space is left between the table extension 4| and the table 35 and this space is filled by weld 4 Id, which is subsequently ground and polished to present a flush table top. 'In order rigidly to secure the table 35 to the plate 42, the latter has a longitudinal g-roove42a at its upper portion (Figure 10A) to receive weld 42?). Upper and lower guides 44 and 43 respectively are formed in the outer face of the plate 12 for suitably receiving and guiding the end plate F of the jointer fence F.

It will be apparent that the table 35 extends laterally beyond the longitudinal upright plate 36 and welded to the under side of this'extending portion is aplate45, the loweredge of which-is flanged inwardlyas indicated at. The table '35 has a longitudinally extending'portion to overlap a portion of the table I8 of the fixed or stationary bed A.

The inner portions of each of'the plates 3B and 31 have their edges upwardly and inwardly inclined, as indicated at 48, with an intermediate recessed portion 49, andinterposed between these ftheir'side edge portions to the inner sides of the longitudinal upright plates 36 and 31. Each of 45 the plates has a hole 5l in alignment with the hole in the other plate and integral with the lower edge of'each plate is an extension 52 which 'has'a narrow neck 53, opposite side edges of'which flare divergentlyoutward. As shown in Figure 10, the extensions52of the plates 50 project outwardlybeyond the inclined edge portions of the longitudinal plates.

Interposed between the two plates 50 and weldedthe'reto is a pair of spacer plates 54,-each of which engages the lower edge portion-of each plate and also the subjacent outwardly flared portion of the extension 52, these spacer plates being welded at their ends to the plates 50 and extensions 52 in order rigidly to secure these parts together.

Connecting-each pair of outwardly flared edge portions of the extensions 52 is a sheet metal strip 55, which is welded in place. The strips 55 slidably engage surfaces of the 'gibs 32, on the lower subassembly of the stationary bed A, and

are somewhat longer than the gibs to allow for desired adjusting movement thereon.

The subassembly T comprises a relatively short sheet metal plate 56, which is disposed betweenand welded to the longitudinal plates 36 and '31. This plate similarly has an extension 5'! provided with a reduced neck'5t', the extension "having outwardly flared or divergent edge portions, as shownv on Figure 1.3.

Spaced laterally from the plate 56 is a narrow plate 59 which is similarly welded at itsends to thepinnerzsides of the lOngitudinalplatesSBl and. 31. The plate 59 is inclined outwardly and connecting the inner side of the plate 59 tothe plate ,56 and: extension '51' is a curved spacer plate 60, which. is shaped toconform to theoutwardly flared edge portions of thelextension- Welded to the outer edge portions-of the spacer plate 60 and the extension 51 on eachsideis a relatively narrow strip 6| which, as shown in Figure'lo, is in. alignment withthe adjacent strip.55 of the subassembly T and'accordingly projects outwardly from the inclined edge portion 48. It will be understood that the guide strips SI of the subassembly-T, are longer than the gibs 32 of the uppersubassembly on the :"stationary bed A (Figure 3)- andslidingly engage same for guiding-the verticallyv inclined adjusting movement of thetadjustable bed B relative to the stationary-bed A; I Y

. The mechanism foreifecting adjustment'of the relatively thereto but cannot shift transversely.

At the opposite end of the rod 63 is a bevel gear 64, which is engaged by a bevel gear 65 on one .end of a shaft which has a hand wheel 66 at the outer end. By turning the hand wheel 66, it will be manifestthat the bed B is caused to move .inclinedly upwardly or downwardly relative, to the stationary bed A; After the desired adjustment. has been made through" the operation of the hand wheel 66, L-shaped screws, 61;.w-hich extend from the outside through holesinthe longitudinal plate l0 of the stationary bedA and .into screw-threadedholes 68 (Figure 8) in the adjacent gibs of the upper and lower subassemblies, are tightened for frictionally holding; the parts stationary, a, conventional floating ib (not shown) imposing a binding action against-the strips 55 and ,6] as will be readily understood by those skilled in this art. v The above described jointe frame structure is particularly advantageous in the case of ex-' .ceedingly long tables where the overhang is' subin such cases not been achieved satisfactorily. By the improved sheet metal welded fabrication above described, not only can true and accurate table alignment be secured, but the weight as well as the cost of the structure is materially reduced. In addition, the strength, ruggedness and durability of the frame parts are greatly'increased so thatthe useful life of the machine is noticeably prolonged.

, It is to be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as defined in the appended claims.
