DESCRIPTION:

BRIEF SUMMARY
The invention has as its object a machine for working materials such as wood, metal and plastic, intended more particularly for hobbyists and model makers and occupying a small space.
Machines of this type are already known, comprising a circular saw, driven by an electric motor, mounted on a base with a table that can be tilted and adjusted in height. It is possible to replace the circular saw blade with an accessory for cutting molds, slotting, drilling, grooving, polishing, sanding, straightening or planing. Electric drills are also known, which are mounted on supports and able to drive vertical shapers, milling cutters, sanders and other accessories in rotation.
The machine according to the invention, which makes it possible to group a larger number of operations in small space, is characterized in that it comprises an upper arm in which a first rotating element is mounted, an upright in which an electric motor is placed and a lower frame in which a second rotating element is mounted, the motor being intended to drive either element in rotation.
The accompanying drawing shows an embodiment of the machine according to the invention diagrammatically and by way of example.
FIG. 1 is a general perspective view.
FIG. 2 shows the inside face of the wall applied against the lower frame and upright of the machine, shown in FIG. 1.
FIG. 3 is a general view in longitudinal section of the machine shown in FIG. 1.
FIG. 4 is a partial view on a larger scale and partially in section of the upper arm of the machine shown in FIG. 3.
FIG. 5 is a partial view in cross section of FIG. 4.
FIG. 6 is a partial view in horizontal section with tear-aways of the lower frame of FIG. 3 on a larger scale.
FIG. 7 is a view in cross section of the lower frame, showing driving of a saber saw.
FIG. 8 is another view in cross section of the lower frame, showing driving of a scroll saw.
FIG. 9 shows the support and return element of the scroll saw.
FIG. 10 is a top view of the plate.
FIG. 11 shows a guide and protection element during milling and scroll cutting.
FIG. 12 is a partial elevation view of the lower frame of the machine shown in FIG. 1.
FIG. 13 shows a detail in partial section of the elements for adjusting the positions of the plate.
FIG. 14 is a partial top view of the plate, showing a guide fastened to the guide bars of the plate.
FIG. 15 is a view in longitudinal section showing the fastening of the guide to the guide bars.
FIG. 16 is a view of the plate in longitudinal section, showing fastening of the guide bars.
The machine shown in FIG. 1 comprises an upper arm 1, an upright 2 and a lower frame 3 on which a plate 4 is mounted. As shown in longitudinal section in FIGS. 3 and 4, a spindlehead is mounted vertically in the upper arm. A spindle or rotating element 68 is driven in clockwise rotation from an electric motor 6 within the upright 2 by a drive belt 7. Rack device 8 for controlling the ascending and descending movements of spindle holder 5 is operated by a control lever 9 against the action of a return spring 10, as shown in FIG. 5. This device also comprises a knurled nut 11 limiting the descending travel of spindlehead 5 by a mobile stop 14 and a knurled nut 12 limiting its ascending travel by a stop 40 solid with upper arm 1.
Driving of spindle 68 of a toolholder 70 is done by means of a first sleeve 67 forming a belt pinion 65 mounted on a needle bearing 66 solid with a second sleeve 71 belonging to upper arm 1. First sleeve 67 exhibits at least a key engaged in a groove 69 of spindle 68.
A current reverser 15 makes it possible to rotate counterclockwise a first takeoff or rotating element 16, mounted vertically in the lower frame from an electric motor 6 by a drive belt 17. This power takeoff 16, which is under a circular orifice 18 of plate 4, is intended to receive and rotate tools such as milling cutters, shapers, sanders, grinding wheels, etc. when the plate is in horizontal position. Moreover, it meshes with a second power takeoff or rotating element 38, oriented at right angles and projecting at the e
