Drilling machine"

Ben subject of the invention forms a -rereinigte drilling "and grinder _s wherein the ^ ial lying in ®ehause the vertical # horizontal shafts, eg * grinding-wheel shafts _s ihrea driven by an intermediate gear of the drilling spindle erlialtea" SxfindungsgemäB is the work shaft by means eiaer in a Bokrtang eiaes Boliransatsea of the housing rotatable sleeve mounted eccentrically ζτχχ axis of the Sohransatses so that by turning the sleeve to xeoiits or link0 a friction cone of the drive shaft with a lower or upper wedge surface of a pulley seated on the drilling spindle to the contact and thereby the direction of rotation of the working shaft is determined the design and operation of the machine are much simpler drives share these training Gr _e "

In the drawing is an example of the object of the invention shown

Fig. 1 shows a view of the machine, partly in section ₅ and

Fig * 2 shows a cross-section after the X & nie II - II äer Fig, U

In bed 1 of the machine, the table 2 can be raised and lowered. On the column 3 resting in bed 1, the upper frame or housing 4 of the drilling spindle 5 can be fixed at the required height Transmission gear drives the drilling spindle 5. On äem & ehütise 4 there are 2 opposing lateral Eohrartsätae 7 »In a bore of Eohraiisataes 7 a sleeve 8 is rotatable _f in which a working shaft 9 is eccentrically supported by ball bearings 1o. On the drilling spindle 5 there is a heating disk 12 which is provided with a groove 15 which is open on the circumference.
