Oil Your Valve Stems.
A particularly useful accessory has just been placed on the market by Brown Bros., Ltd., of Great Eastern Street, London, E.G., in the Joseph valve-stem lubricator. This consists of' ahollow, Openended cylinder of cotton wool, maintained by a surrounding light coil spring. It fits the outside of the valve stem, being situated, -when • in use, between the valvespring collar and valve guide, inside the spring. It is a little longer than the distancebetween the collar and guide, so that it is initially compressed a slight amount, this compression being increased as the valve rises in its guide.
When newly fitted, the accessory, which is made of a soft absorbent material, is thoroughly soaked in oil. Afterwards it needs the supply of lubricant replenishing from • time to time by means of an oilcan. They will be found of greatest service in increasing the efficiency of an engine, and besides providing oil for those neglected items, the valve stems, will in many cases, produce ease of starting by preventing leakage of air along the induction-valve steins.
The price for a set of eight lubricators, sufficient fully to equip a four-cylinder engine, is 20s.

A substantial sprung bracket at the side serves as a support, a Barton)turner is fitted, a red glass at the rear, and a 4-in. hell's-eyeat the front. The prme is 56s, per pair.
Forward Accessories.
We have received from the Forward Motor Co., of Summer Row, Birmingham, a new catalogue of tho firm's specialities. They are, of course, best known on account of the Forward sparking plugs, of which, of course, they are sole manufacturers. These plugs embody a patented construction, the particular feature of which is the gas-tightness which is 'thereby obtained. This construction is exemplified in that plug designated .type C which is particularly recommended for commercial-motor use. Other types are made of course, but all those not having detachable porcelains embody this special con
struction. The usual varieties are listed, special Ford plugs, plugs for American engines, plugs having mica insulation, etc., and last, but not least, the ejector type. This is a plug with unusual firing points, the main electrode having a central hole coned all round to a knife edge ; through this hole the other pointed electrode passes. The type F plug, for the Ford engine, has been specially designed for that purpose. It is made long both in body and in reach, so that it stands well up above the top of the. cylinder, being thus accessible with an ordinary spanner, and it projects well down into the combustion chamber. It is of the detachable -class, that is to say, it can be taken apart for cleaning or repair ; the Claim is made for it that, when reassembled, which operation can be performed with the aid of an ordinary spanner, it is easily made gastight.
The same, firm provides several useful articles whose use is directly • associated with the main item in its catalogue—plugs—among which may be mentioned: the screwed adaptors, by , the aid of which metric-thread plugs, which are British standard, may be used in American cars, and the Forward box spanner, for use when removing or replacing sparking plugs. The former retail at 0c1. each, the latter atis. 6d, each. Leather cases to hold two plugs in each are Useful accessories at 2s. each.
--Apart from the plugs, however, the most important accessory to which reference is made in the handbook, is the Led`l-spring Oiler. As our illustration shows, this consists -of a clamp, which . surrounds the spring, and at the same time' holds in place two pads of felt, one on each side of the spring. Two oilers are required for each semielliptical spring, and they are situated one on each side of the central clip, being positioned half-way along the piece of spring between this central clip and the end of the spring. The carrying clamps are also provided With reservoirs for the oil. When fitting, the pads of felt should be fully saturated with ' thin oil, which oil can be replenished from time to time by refilling the oil reservoirs on the clampsThese oilers are suitable for all types of car Or van, and are made in six sizes, covering a depths of springs likely to be met with in light van construction. They cost 4s.• 6d. each, and it should be noted that a Ford only needs four as a complete equipment of these aiIers.
