Machine for Cleaning Mutton-Cloths and Cotton Waste.
L. M. B. HAMLIN (Leeds) has written to ask if we can give him the name of a maker of a centrifugal or other appliance which will enable him to recover the oil from cleaning rags and waste, so as, if possible, to permit the rags to be used again. We are making enquiries of several makers of centrifugal separating machines, on behalf of our correspondent, but we are sceptical as to the results that can be achieved, in this direction, with cotton waste. We should be happy to hear the experience of any of our readers who have used such a machine.
A Promising Brake Lining.
" Raybestos " is the descriptive name given to a new brake lining which has recently been introduced by Brown Brothers, Limited, whose stores are in Great Eastern Street, E.C. The material is principally composed of asbestos woven with brass wire. The makers claim that it has a very high coefficient of friction, and that it shows no deterioration when employed under condition in which great heat is generated. It is also found that grease, water, paraffin or petrol have little or no effect on its efficiency as a braking material. Two thicknesses are supplied, and the material is made in all widths varying from one to four inches. The full list price for " Raybestos " strips, 5-32 inch thick and
inch wide, which is a convenient size for the brakes on many commercial vehicles, is 3$. 9d. per foot run. It is not claimed that this is a cheap lining, as its manufacture is a costly process, but the maker asserts that it is economical in the long run, as it but seldom requires renewing. Tests, under adverse conditions, over a distance of 20,000 miles, have been satisfactorily conducted.

at* Leather Tool Bags.
In reply to E. H. Doughty (Shepherd's Bush) we find that the black leather tool-bags which were issued by the late London and District Motorbus Company, Limited, were supplied by W. Hammond, Lillie Road, North End Road, Fulham, and it is possible they may still be procured from him. A post-card to the above address should secure the information required.
A Good Vice.
We illustrate, by means of a sectional elevation, Storey's quick-grip bench vice. This appeals to us as being such a simple contrivance that the non-employment of this particular form of construction heretofore is curious. There are no small parts, catches, triggers, or tumblers to get out of order, and the two important parts are : (A) the half nut; and (B) the vice screw, with its special buttress thread_
The end of the screw (C) is an easy fit in the end of the movable jaw piece, and allows the screw to be instantly lifted from the nut, in order to free it. The vices are provided with renewable steel jaws, and are made in seven sizes, with jaws varying from 31inches to 7 inches. The list price of the 4-inch size is 41s., and that of the others pro rata. They are being sold in large numbers, for garage equipment, by W. H. Willcox and Company Limited, of 23, Southwark Street, S.E.
