Typical Hauser horizontal bench miller set up for production work with mainly lever feeds and screw stops. The right-angle casting to the right is a vertical conversion unit 
Superbly constructed - with many minor components in bronze - and probably dating from the first half 20th century the machine is very heavily built - around 40 Kg (90 lbs) - though only 520 mm long, 330 mm wide and 520 mm tall. The table and knee assembly is beautifully constructed with shielded, hand-scarped ways and adjustment by tapered gib strips. Travel is 76 mm longitudinally, 76 mm in traverse and 51 mm vertically.  Able to be moved through 76 mm horizontally, when fitted on the vertical adaptor bracket the head's travel is reduced to 5 mm. Held in large adjustable tapered bronze bearings the spindle takes 9 mm Schaublin collets (draw-tube retained) and would originally have been driven by a round leather rope from a side-mounted countershaft. 

Above and below:  Hauser horizontal multi-spindle drilling machine. The bed was available in different lengths and could be used with a variety of spindles and drilling & boring units. In order to effect a quick change the headstock top could be lifted off and an alternative spindle, one to hold grinding wheels for example, dropped in.  The example illustrated has a high-speed spindle running in ball-bearings and takes 8 mm collets and collet-fitting accessories - like the 3-jaw chuck shown. The multi-head drilling attachment has 4 indexing positions . Accessories included a "swing-stone" assembly and a quick-action, foot-pedal operated collet closer .

An interesting Hauser vertical with a counter-weight at the back of the head to provide a "balanced" action for the lever feed. The well-engineered drive system includes an adjustable jockey-wheel system to accommodate movement of the head.
