A Power-driven Garage Air Pump.
Garage attendants and repair-shop men will welcome the appearance of a really-satisfactory powerdriven air pump, which may be used for inflating tires and for various other purposes in a garage where air is required under pressure. The same type of pump may be fitted to motor vehicles and employed, in conjunction with a steel air bottle, for inflating pneumatic tires, engine starting, and for maintaining pressure in fuel tanks, or for blowing syrens, horns, whistles, etc. The pump we have in mind is one of the simplest and sturdiest we have seen ; it is made by Brecknell, Munro and Rogers, Ltd., of Bristol, the London office of which company is at Finsbury Pavement House, E.C. The main details are shown in the accompanying line drawing, which shows the pump both in section and in end elevation. As illustrated, the pump cylinder is water-cooled, but we believe that air-cooled cylinders are supplied if desired. With this type of pump, very-high pressures per square inch may easily be maintained.
A Milling Machine Analysed.
That enterprising tool manufacturingcompany, Alfred Herbert, Ltd., of Coventry, has issued another of its carefully-compiled booklets dealing with special machine tools. This new publication bears the title " A Milling Machine Analysed," and in the course of its 36 pages, the salient features of an upto-date milling machine are described and illustrated. So great has been the development in modern highspeed tools, particularly milling machines, that many old shopmen have been unable to keep up with the times so far as information on structural details is concerned ; such men will welcome the appearance of Alfred Herbert's latest booklet, Pneumatic Power Hammers.
We have recently, on several occasions, been asked by correspondents for the names of manufacturers of pneumatic power hammers. For the information of readers in general, we now append a list of makers of this class of machinery, similar to that which we have forwarded in response to these enquiries. Buck and Hickman, Ltd., 2, Whitechapel Road, E. Messrs, B. and S. Massey, St. Stephen's House, Westminster, S.W. Ingersoll Rand Co., 165, Queen Victoria Street, E. C.
