 In order to make the object of the invention more concrete, it is now described in non-limiting embodiments illustrated in the figures of the drawings.

 The structure according to the invention comprises a frame (B) of parallelepipedal general shape which is composed of two parallel frames (1-2) suitably reinforced and joined together in the lower part by two fixed crosspieces (3-43. removable crosspieces (5-6-7), one of which at the ends of the transverse bars (5a) are slidably engaged in the upper profile of the frames (1 and 2), while the others have notches (6a-7a). The crossbar (5i with its bars (5a) supports a deliming guide (61). The assembly slides in the upper profiles of the frames, and two bars (30) screwed into them. bars (5a) serve as a table extension whose supports are constituted by removable crosspieces (6 '-7).

The bars (5a and 30) can be distributed from each side of the table (FIG. 2 or positioned in a single category (FIG. 3) as required.

 Parallel slides (8) are fixed between the frames (1 and Zr approximately in their middle part in the height, to ensure the guidance of a stretcher (9) equipped in a known manner with a translation device of the gear type (10) -rack (11) with steering wheel (12) maneuver (Figure 5) or disengageable screw-nut (13> (Figure 6) or by a lever (16) hinged (17> on a fixed rail 8) .In this vertical position of the frame, a sliding tube (14) is secured to the stretcher bearing on a telescopic spring (15) for the return of the tralnard in a position. Of course, it is possible to predict the movements of the sled by these different devices combined with each other, in order to have a precise or approximate adjustment according to the machining operation concerned.

 The stretcher (9) receives in a steerable manner and preferably with intermediate angular indexing positions, a crossed carriage (19) of the lathe type, that is to say formed of a base (19a) rotatable by report to the laggard and a transverse carriage (19a) adjustable in translation relative to the base (Figure 1).

 The transverse carriage (19a) is equipped to slidably receive a clamped collar (20) for attaching a motor member which can be between a portable drill tP)! an engine block or engine. The output shaft of the motor member conventionally presents a drive device of the chuck type (P1) in which is locked a rod (21> arranged end to cooperate angularly with an axis (22) mounted in free rotation on a squared tool holder (23) slidably fixed by its sole (23a) on the transverse carriage (19a) (Figure 8).

 Concentrically to the axis (22) is articulated with play an arm (s4) which can be oriented relative to the vertical leg (23b) of the tool holder by a screw-rack system (62) and locked in all positions between the horizontal and vertical by a screw-nut system (25) cooperating with a slot (230) semicircular branch (23b) whose radius is centered axis (22) (Figure 10>.

 At the end of the arm (248 is mounted for free rotation and bearing a pin (26) for fixing various tools either by nose or by expandable clamp.

 The spindle is rotated by a pulley-type transmission (22a-26a) and toothed belt (27) or by a gear train (FIG. 10).

An upper table (28) secured in any way removable and in several positions on the frames, has a longitudinal slot (28a) over most of its length for the passage of a circular saw (SC) or the like, mounted on the spindle (26), and a longitudinal groove (28b) for a steerable cutting guide (29) and a lateral and medial notch (28c) for the passage of a molding tool (M) mounted on the spindle <26> (Figure 9). The table (28) being positioned on the frame according to the type of operations to be performed
The extensions (30) of the table can be screwed into vertical holes of the frames and connected by a crossbar to form a carrying handle of the structure (Figure 4)
The cutting guide 1295 consists of a support (29a) orientable angle on which slides a squared return (29b) for making angular cuts and for rigid positioning for tenoning operations. The guide can be stopped for cutting pieces by moving the saw with the lever (18).

 At the upper part of the frames 1 and 2) and the category of the spindle (26) is articulated, in two levels, preferably by adjusting and locking means (31), a plate (32> constituting a table additional, which, when in the high position and horizontal or inclined figure 11), gives access to a tool of the type sanding disk or grinding (D).

It also serves as a protective casing and de-warping guide in a vertical position. When it is raised horizontally and placed in the low position (Figure 12), it allows horizontal drilling or grooving operations. In addition, it serves as a squeegee table and for this purpose it has an opening (32a) for the passage of a grinding or molding tool (T) (Figure 14) - mounted on the motor member with axis vertical rotation by pivoting 90 of the frame, only the motor member being cantilevered from the rest plane of the frame.

 In the lower part, the frames (1 and 2) are arranged transversely to receive controlled sliding a set (E) forming forming both jointer and planer retractable inside the frame for the purpose of transport.

This assembly (FIGS. 1 and 13) comprises for this purpose two bars (33> for mounting in frames I and 2 connected at the end by a front crossmember (34) which, in combination with a rear crossmember t35) and spacers. allows the positioning of two demountables t36-37) adjustable in height in order to determine a depth of alignment pass by a rotary tool t383 mounted between the two crosspieces in the opening between the two half-tables with the cutting circumference tangential to the highest semi-table or exit table.

The tool <38) is rotated from the spindle (26) via a pulley transmission (39-40w and toothed belt (41).

 In its middle part, the front cross member (34) is arranged to adjustably guide in height a planing support (42) constituted for this purpose by a vertical tab (42a) connecting the crossbar and a table- horizontal support (42b) for positioning the workpiece by the rotary tool (38).

 Rollers (43) are rotatably mounted between the two cross members on either side of the tool (38) with an elastic return towards the workpiece. and means for driving in rotation of the flywheel or crank type is associated with one of the rollers, to ensure the movement of the workpiece.

 The frame (1) is preferably made in two separable parts (Ib-1c.) The upper part (1b) can be removed (after disassembling the hinge compass of the plate <32), to allow the passage to the motor unit (P> when the frame <B) is arranged vertically (Figure 6) for vertical or angular drilling operations or milling and routing This part (1b) can Other then subject to the frame (2) to form an extension drilling table.

 As seen in the figures, the frame (2) is equipped with a clamping collar (44) for mounting and fixing on the outside of the motor member either directly or by the squared support (20) fixed on a sole.

 For turning operations between points, a driver device (45) is mounted on the spindle (26) or the mandrel of the drive member and a movable rotating counterpunch (46) associated with the slides (6). The working capacity between points can be increased by extension of slides which can be advantageously constituted by the extensions (30> of the crossbar (5) whose free end can be secured to the half-portion (lb> of the frame ( 1) in order to constitute a back support.For the operations of turning in the air, the spindle (is equipped with either a threaded nose, a plate holder room, or a bit chuck.

 Of course, the turning in the air or in counterpoises is performed by appropriate tools then mounted on an adjustable turret (47) carried by the transverse carriage (19a).

The longitudinal movement of the sled is controlled by pinion rack or screw-nut. The control of the screw can be either manual by steering wheel or automatic by connection to the transmission with gear reducer. For the solution tower to reproduce or copy, the screw is replaced by a return spring of the carriage. For longitudinal copying (Figure 15) movable spikes (48> can between sliding mounted on a crossbar attached to the frames (1 and 2) for the positioning of the model parts (PM), or (Figure 16) a sheet metal template ( 49) is clamped between two cross members fixed between the frames (1 and 2) .For front copying (Fig. 16) a template holder (52> may be positioned within the frame (2). connected in known manner to the transverse carriage (19a) which by its turret r47) carries the profiling tool (54i movable against the piece to be profiled (PP) by an operating handle or a screw-nut system, after disengaging the conventional controls A spring (63) provides the recall of the straggler.

 There is further provided a device (D) replacing the tool holder (23) and intended to drive a reciprocating saw to cut or steerable jigsaw (SS). For this, various conventional means can be implemented to transform the.

rotational movement of the driving member (P> in a rectilinear reciprocating movement of the saw, for example and as illustrated schematically in FIG. 17, the motor member is angularly connected to a turntable (56) carrying a crank pin (57). ) on which is articulated a link (58) connected to the frame of the saw and guided in a sliding sleeve (59a) formed on a support body (59) integral with the clamped collar (20).

 It is also possible to adapt to the connecting rod and crank drive mechanism, a scroll saw (SCH) whose upper end is held by a bracket (64i with tension spring (65) of the saw (Figure 18).

 Finally, a divider plate (60) indexed on the spindle (26) in position in the collar (44) and on the frame (2), can be adapted to perform milling operations by reproduction in the horizontal position of the frame or spawning wise or drilling in the vertical position of the frame (Figure 19).

 Note also that a fixed or removable base can be adapted under the frame and that a storage space (drawer, tray, shelving ....) can be arranged in the frame to have accessories and tools.
