The Days Before Power Take-offs, When Friction Drive and Steam-driven Turbines Were Used to Operate the Oil Pump

I

. IN the tipping-gear world there is,

perhaps, no better-known name than that of Bromilow and Edwards, Ltd., Foundry Street, Bolton, Lancs. This year marks a quarter of a century of the establishment of this concern, for it was in 1919 that Mr. J. fi, Bromilow and Mr. M. F. Edwards founded the company, the products of which, to-day, are in use in very considerable numbers.

• Bark 'Street, Bolton, saw the start of activities and it Was here that the first hydraulic power tippers were made and sold. In those days special power take-offs from the gearbox were nonexistent, so that the tipping-gear pump was friction driven, a simple and perfectly efficient means, and vehicles up to 10-ton capacity were so fitted.

Included in the heavier types of machine which were dealt with were steam wagons and, owing to the fact that the engine could not be used as a "stationary " power plant, it became necessary to fix up an entirely independent unit. This took the form of a small steam turbine, the impeller wheel of which ran at a speed of between 20,000 and 30,000 r.p.m. As one of the first engineering concerns in this country to use duralumin for commercial work, it is interesting to record that the turbine wheel was made of this metal.: We understand that, scattered about the country, there is still a number of these turbine-driven oil-pump gears in service: With an increase in demand for tipping gears, the original premises in Bark Street were vacated in 1920, and a bigger works, in Foundry Street, acquired. It may not be generally known that amongst its other activities in the new premises, this company built p.s.v. bodies of both singleand double-deck types.

At the end of 1983, Bromilow and Edwards, Ltd„ became a public company, and it was at this period that

Mr. Edwards ceased his connection with it. At about this time a new factory was built at Park Aoyal, London, to cater for steel, timber and composite bodies.

In 1936, the company took over the manufacture and patent rights of the Principality movable floor and, in 1937, the Wood Hydraulic Hoist Co., Ltd., of Southport, was also taken over, so that these units became complementary to the range of B. and E. power. operatedtipping mechanisms. In view of the nature of this corn

pany's products, it will be obvious that its war-time activities have been fairly extensive, and although little can be said of these efforts it can be mentioned that they have been concerned with aircraft and Fleet Air Arm equipment, artillery, and transport and Aghting vehicles. For over three years it has been working on hydraulic mechanisms for fighting vehicles.

The long and specialized experience of the company in hydraulic gear of many types has' resulted in its now having a comprehensive range of equipment, amongst which may be mentioned the following: B. and B. power-operated endand three-way tippers; Wood Hoists, together with wood arid steel bodies of all types and tonnages; the Principality .moving Hoar for commercial and-refuse-collec

ton work; hydraulic cranes ; power. operated forward and reverse winches; the Principality Bulldog moving-floor trailer which has been specially designed and built in coniunction with J. Brockhouse and Co., Ltd.; mobile hydraulic trolleys for lifting complete aircraft; hydraulic furnace tilters and hydraulic manipulators to facilitate the welding and assembly of large units.

Experimental and research work has always figured in the concern's activities, and this has not necessarily been confined to tipping gears.

It may not be generally known that in the early days of talkie cinemato

graph apparatus, the company experimented and produced a number of machines at a time when the " sound " • came from records.

The company, progressing with the times, eventually produced the then most modern type of apparatus in which as now, the sound track was on the side of the film, The company is fully alive to operators' requirements in the matter of tipping gears for the post-war years, and new designs and materials are well to the fore and will be made available so soon as conditions permit.
