12 Claims.

'This invention relates to planers and more particularly to machines adapted to plane and finish very large pieces of fiat work such as ship plate, such work pieces ranging to a dimension of fifteen feet in width and forty feet in. length. For the planing and finishing of such work pieces it is very desirable, and of great advantage, that the work piece may be planed and finished at one setting thereof, both as to its surface, its sides,- and also as to its ends,-which ends are often not at right angles to the sides of the piece. A principal object of the invention. is to provide means whereby in a single structure, and with a single setting of the work piece, not only the sides and surface of the same may be planed and finished, but also the ends, which may be at more or Aless an angle other than a right angle to the longitudinal'axis of the work piece. To these ends theinvention as herein shown is embodied in a machine of double run-way, traveling cross-rail type, the work to be planed being mounted on a suitablework holding device between the run-ways. The invention comprises mechanism for planing not only the surface and sides of the work piece, but also the I ends thereof, and still further, provision for planing the more or less oblique ends of the workV piece and for planing scarfing cuts therein. It is desired at this point to emphasize the advantage gained with the construction of the present invention of not having to move and re-set these large work pieces to completely finish the surface, sides, and also the ends thereof. i

The foregoing and other objects and advantages of the invention will be better understood from the following detailed description taken in connection with the accompanying drawings, and the distinctive features of novelty will be thereafter pointed out in the appended claims.

Figure'lO is a detail elevation looking endwise of the' cross rail, of the form shown in Figure 9.

Ill, indicate the two spaced apart run-ways of the machinewhich is generally of the usual traveling cross-rail type. In troughs provided in the upper faces of these runways screws |2, 13 are mounted, these screws being supported in the usual manner on bronze shoesfspaced at intervals throughout their length, and being equipped with suitable end thrust bearing's at each end thereof, and with long bronze nuts borne by the saddles to engage the screws, these features being of usual construction and not herein shown. The two screws |2, 13 are driven by a reversing drive motor M having shaft extensions |5, |6 from itsl respective endswhich are connected to the screws |2, |3 by suitablefgearing. The motor |'4 which operates the crossrail may be controlled in the usual manner by a master switch mounted on one of the crossrail saddles, and engaging adjustable dogs on the run-way as is usual in this general type of machine. 15, |6 denote saddles fitted to operate on run-ways l, II and bearing long bronze nuts engaging the screws |2, |3 in the usual manner.

I'l, |8 denote pedestals mounted on these saddles, and to which the ends of the cross-rail |9 are secured. i One feature of the present invention relates to means for optionally mounting and clamping this cross-rail to extend ina direction other than at right angles to the longitudinal extent of the run-ways, and for this purpo'se one of the pedestals on which the crossrail is mounted, shown as the pedestal |1 is pivoted for turning movement on the saddle |5; this pedestal base having for this purpose a short. depending circular boss orprojection I'IA which fits a socket recess provided therefor in the saddle [5.` This pedestal is firmly clamped to the saddle in any adjusted condition-by a series of clamp bolts l'lD which are passed through arcuate slots HB of the base fiange HC of the pedestal Iand screwed into holes tapped therefor in the saddle. The other pedestal IB is permitted thebrequisitepmovement for vthe swinging of the cross-rail by having bolts 20 with T-heads engaging a series of parallel undercut T-slots 29A of the saddle. These bolts extend upward through short transverse slots 29B of the fiange base IBA of the pedestal la which is engaged by nuts threaded on said bolts. llC indicates a means for adjusting the pedestal with respect to the saddle comprising a screw with geared connection to a wrench engageable member-it being understood that such means is merely illustrative of any suitable means` for accomplishing this result. The cross-rail 19 is thus adapted to be adjustably clamped so that tool heads thereon may plane the end edge portions of Work which are at other than right angles to the longitudinal extent of the work as indicated at W' on the Work piece W. Such'work piece W is mounted on a suitable work holder shown as comprising a series of steel beams 25 extending between the run-ways.. The work is clamped to these beams by suitable straps and bolts 21A. In order to properly hold these large work pieces and still leave the side and end edges clear for the operation of the tools, it is found desirable to tap these work pieces underneath to receive the strap bolts 25A. The work piece as illustratively shown in Figure 4 is tapered longitudinally, and the straps and bolts 21A are provided with the requisite filler pieces 21B so as to block up the work piece and present its top surface in a horizontal plane. 2|C, 21D denote end stops for the work piece which may be removed when cross planing the ends of the work as presently described.

As shown in Figure 2, two swiveling type planing heads 22, 23 are adjustably fitted on the crossrail |9, the head 22 being shown as adapted for planing the Vtop surface of the work, and the head 23 shown as having a depending extension 23', bearing a tool head 23" adapted 'for planing the longitudinal side edges of the work piece. When .these heads are in use the cross-rail is operated back and forth along` the run-ways by the driving motor M as already set forth. Motors 24, 25 are provided at the ends of the crossrail with driving screw connections 26A, 26B for horizontally moving the planing heads 22, 23 respectively along the crosszrail and motors 25, 21 borne by the respective tool heads are provided with screw connections indicated at 21A in Figure 9 for moving the tool rams vertically and angularly on their respective heads 22, 23. The operation of these several motors is in practice automatically Controlled by switch mechanisms well known in the art and which it is not deemed necessary to illustrate herein.

In accordance with my invention a third planing head 28 is mounted for movement along the cross-rail 19. This planing head is equipped with a reversing drive motor 23, which through spiral gearing 3|] operates a spiral gear 3|, mounted on said planing head to engage a rack 32 on the cross-rail for driving said planing head along the cross-rail. It will be understood, however, that this planing head could also be screw driven in a similar manner as already described for the cross-rail drive, With a course only one'screw being required-this screw being driven by a re- Versing planer drive motor similarly as the motor M for the cross-rail. In accordance with my invention the planing saddle 28, which constitutes the novel cross-planing device of my invention is equipped With an auxiliary lrail support section 33 extending outward at right angles from the saddle and the cross-rail, it being noted that this aaoa'rev the ends of the work piece W. rIn such operation.V

the cross-rail |9 is heldv stationary and the tool head 34 is driven back and forth along said crossrail by the drive imparted .from the motor 29.

The necessary small horizontal feed movement of the saddle 33A and the cross-planing tool head 3d, on the auxiliary rail 33 in a direction transverse of the cross-rail, is derived from the motor 35, borne by the saddle 28 through a usual screw or like connection 'to the saddle 33A from said motor. The tool head 34 has mounted at the top thereof a motor 36 for imparting the necessary Vertical and angular movement tothetools By the mounting of the cross planing tool head 34 on the auxiliary rail 33 extending-at right angles to the main cross-rail it is possible to feed the head 34 .in this direction at the end of each cross planing stroke When planing horizontal surfaces at the ends of the work, such as scarfing cuts, and also to feed the tool in towards the work between successive planing cuts across the Vertical surfaces of the ends of the work. The main cross-rail i 9 is clamped to the vrun-ways when using the cross planing head, and this aux.- iliary rail 33 enables the tool head 3d to'be moved or fed small amounts in a direction parallel with the longitudinal centerline of the machinawithout having to move the whole cross-railafter it is positioned and clamped.

My invention also` comprises improved means for producing scarfing or taper cuts along any purpose it is contemplated that each of the described tool heads will be arranged to receive the taper attachment to'be now described, though it is herein shown as applied to only one of them.l Referring to Fgure 9 the tool vhead 22' mounted in the saddle 229 and slidable on the lcross-rail |9,

has feed movement imparted .thereto from the motor 26' through worm gearing 23". Brackets 37, 38 are attached to the cross-rail at a proper distance each side of the saddle 22il and have clamped thereto a taper bar 39 which extends across the face of the planing head. The taper bar 39 is clamped to brackets 31, 38 so that it extends at the precise angle of thescarfl to be planed as indicated at S on -the work piece W. 6.13 denotes a precision limit switchmounted on the face of the tool ram 22" of the planing head 22'. This switch controls the operation of motor and therefore causes the tool to be fed downwardly along with its lateral feed just enough to produce the scarfing cut S. It will be understood that a like result and employing a similar taper bar might be obtained by mechanically controlling the downward feed of the tool, instead of doing this by an electric motor. The described machine is thus adapted to finish completely with a single setting of the work piece, a flat work plate that is either rectangular or with one or both ends thereof at more or less of an oblique angle, and to finish both the top surface, the side edges, and the end edges of the piece, as Well as to produce scarfing cuts along any one of these edges.

I am a'ware'that'the invention vmay be em- 40 I one of the four sides of the work piece. For this bodied in other specific forms as to its several features, without departing from the spirit or essential attributes thereof, and I therefor desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than the foregoing description to indicate the scope of the invention.
