Advice on Welding Matters.
We have been asked by the British Acetylene and Welding Association, 103 and 104, Cheapside, London, E.C., to announce that they have now inaugurated a consulting department for the purpose of assisting in the elucidation of welding problems. They propose to give expert advice and technical assistance gratuitously. Those who are interested in this matter should apply to the Secretary of the Association at the address given above.
A Protective Leaf-spring Covering.
Various subsidiary devices have been used in the past with a view to assisting the leaf-spring suspension of a vehicle, but we think that we can safely say, with perhaps one or two exceptions, that these accessories have met with little success. Then, again, the fitting of a supplementary device does not remove or remedy the cause of the trouble but simply performs the ordinary functions which the leaf-spring should be called upon to do. Additional springing devices should be altogether unnecessary if the springs receive proper care and attention. With the idea of dispensing with these auxiliary devices Brown Brothers, Ltd., Great Eastern Street, London, E.G., has recently placed on the market an interesting accessory which, it is claimed, will assist the springs to retain their original resiliency. This device, which is called the Duco spring gaiter, ensures a neat but not a glove-tight fit round the spring, which is therefore protected from extraneous matter of all kinds. The gaiter is not merely is bandage, but is a flexible, weatherproof, greaseretaining sheath, which is made of black leather reinforced with felt inside. A channel is cut in the felt for the grease, which, as the springs alternately compress and rebound, finds its way between the loaves, so that they are constantly lubricated. The lacing of the cover's:1g is on the underside of the spring, so that there is no risk of water's penetrating the outer cover. The gaiter can be fitted quite easily, and when once in position it is permanently fixed. All the attention that is necessary is to see that the supply of grease is occasionally replenished. We understand that the accessory can be supplied to fit the leaf-springs on any make of vehicle.
It will, of course, be obvious to our readers that such a device as this gaiter, which automatically lubricates the leaf-springs of a vehicle, will lengthen their hie, and at the same time will save the purchase of shock absothers and other aidz. The Riches Pull-u-Out.
The hue illustration which we reproduce herewith shows an interesting little mechanical device which is being marketod by G. T. Riches and Co., Ltd., 19, Store Street, Tottenham Court Road, London, W.C. The accessory is claimed to be most Useful in enabling a vehicle to be safely extricated from soft ground, a ditch or any other awkward position.
It consists of a substantial winding drum with gears inside which engage with a small gear at the end of a long ratchet crank. Forty feet of steel cable with a pulley and two chains seven feet long with hooks at each end complete the device, which is quite appropriately called the Pull-u-Out.
Three stakes, each 13 ina, long, are provided with each pulley. The stakes, when in use, are set into the ground, tandem fashion, sloping towards the object to be pulled, and not, as might he generally subposed, away from it. It is quite a simple matter to drive these stakes into the ground, but, once they are firmly fixed, it is a most difficult task to extricate them. Of course, when the pressure is released, the stakes will be found to come out of the ground quite easily.
The whole Outfit, including stakes and chain, weighs only 2'3 lb., and the space which it occupies is of little account. The uses of the device are not limited to those of commercial or other vehicles ; in fact, is stated that the accessory is as useful for many other purposes, amongst which we may mention wire stretching and lifting. Pull-u-Out should certainly be found to be of considerable utility in both garage and repair shop, where it can be used to take the place of the more usual form of chain blocks. The device is inexpensive, and can be supplied from stock.
