Very much bigger, heavier and more useful than its smaller brother, the larger version of the Universal was 11' 6" long, approximately 3' 8" wide over the handles (with the milling table in its centre position) around 78-inches high and weighed in the region of five tons. The machine combined a sliding, surfacing screwcutting lathe, a universal milling machine, a sensitive drill, a universal grinding machine and a bench grinder with a built-in twist-drill grinding jig. A single 6 h.p. 3-phase motor was used to drive the lathe and universal milling machine with separate motors for the drill and grinder. Although the same motor was used by lathe and miller, their operation was entirely independent, though they did share the same drive gears within the headstock and slipping clutches to protect the feed mechanisms. However, when the grinding machine was in use, this prevented the lathe and miller from being used. Two suds pumps were provided, one for grinder and one for the other three machines. Oil reservoirs were used in abundance - for instance, it appears from an external examination that the feed screws for the milling table each ran in their own oil bath - and the machine was fitted with a pressure oil supply to the main headstock that incorporated a filter. Lathe: Cast with heavy diagonal braces between its walls, the V and flat-way lathe bed was very substantially constructed and of a useful size. The centre height was around 6 ½ inches with a small removal gap piece allowing an extra 4 inches or so on diameter to be turned. The distance between centres was approximately 48 inches and 9 spindle speeds of 21, 30, 45, 74, 106, 161, 244, 352, 533 rpm were available controlled by the juxtaposition of levers on the front face of the headstock. A separate shaft drove the power sliding and surfacing feeds with the drive passing through a safety-overload clutch. Individual engagement levers, with reverse, were provided for both the feeds and the leadscrew - and handy adjustable stops fitted for the automatic disengagement of the longitudinal (sliding) feed. Fitted with a screwcutting gearbox able to provide a limited range of pitches: 3.5, 4, 5, 6, 7, 8, 10, 12, 14, 16, 20 and 24 t.p.i. A set of changewheels was available to extend this range including a 63t metric translation wheel - a useful precaution on a lathe used for emergency repairs. 12 rates of sliding and surfacing feed were available from 0.005 to 0.040" per rev sliding and from 0.0025" to 0.02" surfacing. Two unusual touches were the provision of a series drain holes in the valley of the rear V in the lathe bed and a cross-slide wiper with an overhanging protector. Milling Machine: Very heavily built, the milling-machine element was a proper "universal" - that is, a combined horizontal and vertical type with a three T-slot, 40" x 10" table able to be swung some 50o either side of centre. 23" of longitudinal travel was provided, with 7" in cross traverse and 13" vertically (though it is possible that an alternative specification was alsom produced with slightly greater travels). With a heavy-duty, 40 International taper the spindle had speeds that ran from 21 though 30, 45, 74, 106, 161, 244, 352 to a maximum of 533 r.p.m. Fittings were provided for a front brace support for the table and knee assembly and, at the right-hand end of the table, a take-off drive to operate a power-driven rotary table - the control for this were, very conveniently, built into the table power-feed arrangement with an attached feed-rate chart. In addition, the makers offered an ordinary dividing head and powered rack-cutting and slotting attachments. Grinding Machine: A complete, self-contained cylindrical/universal grinding machine was bolted in place parallel to and behind the lathe bed and carried just a Ryder badge. With a 10" swing over the bed and a maximum capacity between centres of 24", it provided the usual range of facilities including (with accessories) tool and cutter grinding and a limited surface grinding capacity. Although the table's reciprocating motion - 6.5 to 69 inches per minute - was mechanically driven, its gearbox was flexibly mounted to aid smoothness of power delivery. The wheelhead motor was rated at 3 h.p., that for the workhead 1/4 h.p. and for the table traverse 1.5 h.p. Drilling Machine: Although in post-WW2 years Adcock and Shipley stopped making drilling machines, in earlier decades that had offered a very wide range of heavy-duty types - and it was on this experience that Ryder drew when cooperating with the design. Of very heavy construction the 15" x 20" T-slotted table was able to be elevated (by a telescopic screw) through some eighteen inches; the throat depth was twelve inches and a No. 3 Morse taper fitted in the quill. All-geared, with speeds from 85 to 1220 r.p.m., the drill was able to machine a 1.25" hole in mild steel. The 6-inch stroke of the spindle could be hand or power driven - the latter having 4 rates from 0.0055" to 0.0162" and engaged by pulling on the quick-feed capstan handles. Unfortunately, on the examples seen, the full-circle fine-feed handwheel did not carry a graduated micrometer collar. Should you have a Universal with Adcock & Shipley or Ryder badges of either size, the writer would be very interested to hear from you..
