Jaspar Milling Machines

A manual is available for the Model 2CR and a catalogue set for the others

Manufactured by the machine-tool maker, Society An. Ateliers Jasper of 2-4 rue Jonfosse in Liège, Belgium, the Jaspar range of milling machines was listed during the 1950s as the Types 2CR and 3CR Universals; the 3MVS and 3VS Verticals and  Jaspar-Gardier 3MCB Universal. Other models were also manufactured but, as far as can be discovered, those were the only types sold into the UK where they were marketed by George Cohen & Sons Ltd. Of Stanningley near Leeds.
Smallest of the range was the 2CR, this being  a "Universal", a term that today has become confused with milling machines designed to fulfil, equally well, the function of both a vertical and horizontal type - but its true meaning being a horizontal miller where the table can be turned on its vertical axis. While this system allows, of course, work to be machined at an angle, it also, and more importantly, allows for the generation of helical gears by the use of a dividing head driven (usually) by a train of gears from the table's power-feed mechanism.
Intended for what the makers described as "
small toolroom and light precision work", the 2CR had its main frame cast in a close-grained iron to Brinell 210 to 230. The heat-treated, alloy steel cutter spindle, ran in adjustable Timken taper roller bearings. Driven by a 2 h.p. motor, nine spindle speeds were available, these ranging from 67 to 1060 r.p.m. as standard but with the extra-cost option of 95 to 1500 r.p.m. as a special order. The drive passed through a two-lever-controlled gearbox built into the column, the case-hardened and ground-profile gears being carried on splined shafts running ball races.
Just one table was available, this having three T-slots and measuring 37.5" x 8.75" (950 x 220 mm) with 22" (550 mm) of longitudinal travel, 6.375" (160 mm) in traverse and 17" (425 mm) vertically. Powered by a 0.5 h.p. motor flange-mounted to a two-lever-controlled gearbox slung vertically beneath the right-hand end of the table, six rates of power feed were available - but only in the longitudinal direction. Feed rates ranged, as standard, in distance per minute, from 0.4375" to 4.5625" (11.8 to 119 mm) or optionally, at extra cost, from 0.6875" to 7" (17,5 to 175 mm). The usual pair automatic knock-off stops was provided, sliding in a T-slot that ran down the front face of the table. Hand engagement of the feed was by a directional lever placed exactly on the table's centre line; unfortunately for those on production work (and as far as is known) rapids were not fitted as standard, nor available as an extra. The maximum distance from the spindle nose to the top of the table was 18" and the minimum 0 (425 and 0 mm).
Fitted as part of the standard equipment were a full electrical installation, an electric coolant pump and piping, one cutter arbor and rings, cross braces to support the end of the cutter arbor, spanners and an instruction book. A range of accessories was available with items including a dividing head with rack and worm cutting attachments, hand and power-feed rotary tables, plain and swivel-base machine vices, and alternative diameters of cutter-holding arbors 7/8", 1" and 1.25", etc.
The 2CR weighed approximately 16 cwts (1792 lbs/800 kg).
Details of some of the maker's other models are below.

Jaspar  Type 3VS Vertical Milling Machine

Fitted with detachable crank handles, the cross and vertical feed screws of the Model 3VS were fitted with micrometer dials holding sun and planet pinions - an epicyclic gear mechanism--the same system being used on some dual inch/metric dials to give a more accurate reading from one scale to the other
