The DESMO FLEXI for exposed joints Ninety per cent. of the wear on exposed joints of Motor Cars and Motor Cycles is due to the rubbing and grinding effect of road grit that has adhered to the grease intended to lubricate. The only positive prevention of such wear lies in the total elimination of grit, and the complete retention of the lubricant. Leather Bindings, Metal Covers and Shields are at best an inefficient make-shift. Leather quickly creases, puckers and cracks, thereby providing an outlet for grease and an inlet for grit. Metal Shields, while preventing the ingress of a certain amount of foreign matter, make no But henceforward the question of lubrication with a total elimination of foreign matter is solved . . . There is the "Desmo Flexi Lubri Cover." The very simplicity of the "DESMO FLEXI LUBRI COVER" is its greatest asset. Simple to fit to any part of the Car. ONCE FITTED IT MAY BE LEFT UNATTENDED FOR, AT LEAST, A SEASON'S RUNNING. No more weekly greasing and oiling, no more periodical paraffin brushing. The "DESMO FLEXI LUBRI COVER" renders them unnecessary. Consider what this means, whether your Car or Motor Cycle is used for business or pleasure. The illustrations alongside and below indicate a few of the uses of the "DESMO FLEXI LUBRI COVER," while that overleaf shows one type in detail. Produced in Rubber, made to a particular formula, the "Desmo Flexi Lubri Cover" ensures absolute grease retention. The Tongue and Groove Connection between the two centres ensures a perfect union, yet permits free moving of the joint. The Cover is therefore, in effect, one piece - definitely sealed at every point and in any position. "DESMO FLEXI LUBRI COVERS" are being standardised by the Leading Car Manufacturers, having been passed and accepted by the most important Designers and Engineers associated with the Automobile Trade - simply because they obviously supersede any other type of Protector. The leading Motor Agents have congratulated us upon this invention and will fit "DESMO FLEXI LUBRI COVERS" to all Steering and exposed moving parts. Motorists who have had to pay for adjustments and parts, necessitated through frictional wear - the effects of grit - realise the absolute necessity for them. "DESMO FLEXI LUBRI COVERS" are supplied boxed in Sets, and retailing at PRICES from :- 12/6 per set of four, complete with DESMO FLEXI GREASE, for Steering parts, etc., of Cars; and for O.H.V. Rocker Arms of Motor Cycles, 3/6 per set, complete with DESMO FLEXI GREASE. IMPORTANT. When ordering, please state make and year of Car, and in the case of O.H.V. Motor Cycle Engines, state make and year. REMEMBER. Once fitted, the part protected from grit requires no further attention for months and there'll be no wear - anywhere. DESMO LIMITED.

The illustration of a car chassis below indicates a few of the joints that should be "Desmo Flexi Lubri" covered. The "Desmo Flexi Lubri Cover" is available for many types of joints, it is easily fitted and once in position can be forgotten. STEERING. These illustrations show the "Desmo Flexi Lubri Cover" fitted to the Drag Link and Track Rod of a Motor Car. The two views show the actual joints and the manner in which it is completely covered by the "Desmo Flexi Lubri Cover" without any restriction of movement in the joint, and also the first to show signs of slackness through frictional wear, due to rust and grit. The "Desmo Flexi Lubri Cover" is essential. BRAKING. Because the Universal Joints on the front wheel brakes of a Car have been covered with leather, etc., or the "Desmo Flexi Lubri Cover," is it not only is it absolutely grit-proof, but it is also waterproof, it will not crease or crack as does leather. The brake mechanism is given perfect free movement in any position. Wear through grit is eliminated. Efficient and reliable Braking Systems are maintained by the "Desmo Flexi Lubri Cover." SHOCK ABSORBERS. The illustration here shows a "Desmo Flexi Lubri Cover" fitted to the moving joint of a Houdaille Shock Absorber. The perfect protection provided means fewer adjustments, longer life and BETTER shock absorption. "Desmo Flexi Lubri Covers" are also designed for other Shock Absorbing parts, i.e. - Brake Pull Rods, etc., etc. MOTOR CYCLE ENGINES. Each year a new type of O.H.V. Engine is produced, including J.A.P., A.J.S., Sunbeam, Triumph, Norton, Bradshaw, Anzani, etc. There is a type of "Desmo Flexi Lubri Cover" for each of these engines. Rocker Arms of a Motor Cycle Engine are subjected to more exposure to dust and dirt than any other part of the Engine. They should be fitted (as shown in the illustration) with the "Desmo Flexi Lubri Cover" to prevent grit, moisture and any foreign matter, allowing the Rocker Arms, etc., to be constantly working always in lubricant. This obviously, reduces friction and wear. RECHARGING WITH GREASE. The process of recharging the "Desmo Flexi Lubri Covers" is a simple one. By separating with the fingers the joint of the "Desmo Flexi Lubri Cover" and inserting the point of the tube of grease provided, the whole of the interior of the Cover is recharged into the cover. The joint is then re-united. The whole is a half-minute job, only necessary once during a season's running. | ||
