Subsidiary Suspension Systems Which Come into Action when Ordinary Springs are Fully Loaded
VARIATIONS in load, extremely bad surfaces and special body requirements sometimes demand the employment of auxiliary spiings which come into action when needed to meet a temporary additional burden. Lion Helper springs have been introduced to meet this need ; they are handled by R. M. Papelian, Ltd., Trico House, Edgware Road, Cricklewood, London, N.W.2, and are marketedin forms suitable for Ford and Chevrolet chassis. It should be noted that in all eases the leaves of the auxiliary springs are not in action until the ordinary springs assume their fully laden: position, in other words, the Lion springs do not merely stiffen up the normal suspension.
In consequence of this provision the unladen vehicle rides as freely as one without Helpers, but the additional leaves Can come into action to counteract a temporary overload, to oppose side sway, or to prevent excessive flexing of the ordinary springs when
some extraordinary circumstance is encountered.
For the Ford 10-cwt. chassis the Lion Helper set consists of a pair of quarter-elliptic springs and the two axle pads. The cost is f...S (fitted). Attachment is made to the lower flange of the frame, and there is an abutment against the vertical portions of the frame channels.. For the Ford 30-cwt. model there are two designs, one censisting of a pair of reversed quarterelliptic springsand the other of a pair of semi-dliptics ; the former set costs. £8 10s. and the latter £9 10s., in both cases including installation charges. Either type can be obtained to suit the tapered-frame or straight-frame Ford chassis and either pattern of Lion spring can be mounted on the short or long-wheelbase. Ford. The quarter
elliptics are .anchored to the frame and abut against pads on the axle easing, but the semi-elliptics are secured to 'the axle Casing and work in guides bolted to the frame.
. These sets are sold through Ford dealers and it is important-to'note that. no changes are necessary in the Ford layout, neither is it necessary to drill holes in the frame ; all attachments are made by clamps employing bolts.
In the case of Lions for the Chevrolet 30-cwt. model the cost is 19 (fitted), and they are sold by Chevrolet agents. Semi-elliptics are adopted for this make ; .extra long U clips secure the auxiliary leaves above the main ones. On the. frame are two Z-shaped brackets for each spring ; contact between the free ends of the Lion springs and these brackets is made only when unusually heavy work is on hand. Again there are no holes to be drilled or frame alterations to be effected. Installation can be made without removing the body.
