Made in Switzerland, the heavily-built round-bed Essaime lathe is rare with few details available. Though very different in detail, in size and robustness it resembles in design the Canadian Cowan.
The example shown below might have a centre height of around 125 mm, take perhaps 500 mm between centres and is fitted with screwcutting by changewheels. Drive to the leadscrew, that runs down the centre-line of the bed, is by a dog clutch,, the long operating lever of which pivots from a point half-way up the headstock end bed foot.
On the back of the bed is what might be the holder for a copying attachment - though this cannot be confirmed.
Drive appears to come from - judging by its ornate design - must be the original maker's countershaft unit.
Should any reader own an Essaime, or have details of the manufacturer, the writer would be delighted to hear from you.
