Swift Slot MachinesSwift Post-WW2 Models L & RL LathesEarly Swift Lathes
Swift Slot Machine GameGeorge Swift and Sons were once a well known English machine-tool company based at the Claremont Iron Works in Halifax, Yorkshire. The company was founded in 1884 and had a long and successful history supplying a wide range of not only lathes, for which they were probably best known, but also numerous different kinds of conventional, multiple-head and radial-arm drills, slotting, shaping, planing, roll grinding and fluting machines as well as twist drills, rotary and box table and other engineering accessories.
The Model L Series lathes, shown below and here, were current during the 1930 and 1940 and designed with a speed and feed range such that they could not only handle the high-speeds and fine feeds required to get the best out of the then current of tungsten-carbide tools but also be capable of the lower speeds and heavier cuts possible with ordinary high-speed steel. The result was a roller-bearing machine, with a large capacity gap bed, that was just as capable of turning small shafts at high speed as handling the largest casting that could be bolted to an oversize faceplate running in the full depth of the bed’s gap. After World War 2, the Company’s model designation was changed with two sizes of the Model L3 continuing to be built (with minor modifications) as the V3 with swings of 18.5 and 22.5 inches. The lathes were all fitted as standard with a large flat-belt input pulley which could be driven from overhead line system or, if required, adjustable rails could be supplied fitted to the back of the bed able to accept a suitable electric motor; in this latter case the input pulley was changed for one with V belts, the short distance between the motor and pulley being judged insufficient to allow a good wrap-around for the flat belt to transmit full power. A further addition supplied as standard with the V-belt drive lathes was a combination multi-disc clutch and Ferodo-lined brake unit, controlled from a handle fitted to the left-hand face of the apron and operating through a long control rod set parallel to the leadscrew and powershaft. The position of the operating handle was unusual, for most other makers chose to fit it to the right-hand side of the apron, to take the operator’s hand away from red-hot turnings spiralled from the cutting tool and out of the way of large, heavy and potentially errant lumps of unbalanced material fastened to the faceplate. Perhaps the workmen of Yorkshire were made of sterner stuff than others, and could not be bothered to consider such trifling matters.
The apron was a model of simplicity and ease of use with a patented single-lever control to select, interlock (against leadscrew engagement) and engage the power sliding and surfacing feeds. As the Swift company pointed out, a few seconds saved during each change of operation might not seem to matter but, multiply the number of changes made each working by the number of lathes employed in the factory and the seconds turn to minutes, the minutes to hours and the profit on the now larger pile of parts on the floor will mean that you have either gained a workman for free - or can afford to employ one extra. Various other aids to faster production were also offered including duplicated electrical controls mounted on the apron.
Tailstocks were all fitted with bored-through barrels and generously-size capstan handle operation; although in some ways a clumsy design to use, this system did allow a decent length of travel to be obtained with good support when the barrel was fully extended.
Because many purchasers required special features on their lathes, Swifts offered a customising service and were able to build machines which differed from standard in a number of ways and which might have had, for example: longer, shorter, straight, gap or even sliding beds, automatic trips and stops to the carriage drive, increased or decreased centre height, rotating capstan heads on the cross slide for production work or adapted as special-purpose surfacing, boring or roll-turning lathes where a dedicated machine might not have been an economic proposition.
