RESTRICTION UNITS ON BIJUR LUBRICATION We have received samples of the K.T.A. type Duralumin Drip-plugs, which are the latest development of Mr. Bijur, together with duralumin connections etc. These are already used by Springfield, who discarded "banjos" in their favour, and Messrs. Luvax the Bijur representatives in England advocate their adoption on R.R. chassis. The advantages we should gain by using them are :- (1) There would be no soldered joints, all connections being accomplished by a taper sleeve and nut as shown in the attached sketch. Hence a broken pipe accidental or otherwise is quickly replaced without the aid of the coppersmith. This would be a great asset in service. (2) Abolition of large pillar connections and 'double' drip-plugs, now necessary to make pipe lines independently removable. (3) The drip-plug body would be composed of one material, instead of two as at present. This would greatly assist manufacture according to Messrs. Luvax, who at present are obliged to scrap quantities of our own type, as the inner brass portion distorts slightly on pressing into the steel casing. | ||
