Sumps
A Simple Compressedair Machine for Flushing Casings. A Neat Onegallon Fuel Pump EXTRA.u.l'ING grease or heavy oil from a gearbox or axle sump is not an easy task, unless the parts ba completely dismantled. A coarse taken by many is to flush out such a casing with paraffin, but this has an attendant danger in that any liquid remaining may cause dilution of the new lubricant. To avoid these difficulties an interesting item of garage equipment has lately been placed upon the market by 11. A. Moore and Co., Ltd., 150, Southampton Row, London, W.C.1. It is known as the Bennett Air-way Flusher and is priced at £8 12s. 6d.
The flusher operates from any compressed-air system. If a cleaning fluid be used, agitated by the air passing through the device, it will flush out the inaccessible corners of casings, etc., whilst the vacuum which it can exert will remove any liquid which remains after draining.
As will be seen from an illustration on this page, the deslice consists of a one-gallon steel container to which is connected a long hose for coupling to the compressed-air line, whilst the hose with a metallic extension is used for forcing the cleaning fluid into the casing at high pressure or sucking out the liquid from the part which is being cleaned.
When an operating lever on the control valve is depressed and the operator's thumb is over the air-exhaust port, liquid in the container is expelled by air pressure upon it. To obtain a suction effect the lever is depressed but the exhaust port is left open. This draws off the liquid from the casing which is being cleaned and fills the tank of the flusher.
The weight of this . device is 9 lb. It can be connected directly and easily to any compressed-air installation.
Another interesting item of garage equipment, particularly to operators of small commercial fleets, is the Bennett fuel pump for dispensing petrol from underground storage tanks. It is not intended for the resale of fuel. Each stroke of the piston delivers one gallon of fuel. The discharge is from the top of the pump and it has adjustable quantity stops, so that a gallon or a gallon may be delivered. All the moving parts are enclosed and the handle can be locked to prevent theft.
Amongst the features of this pump are the air-release valve which ensures rapid drainage, a shut-off nozzle on the hose to prevent wastage and a counter which records each delivery up to 10 gallons and then repeats. Brass is used for the cylinder and valves and a glass window is installed in the delivery outlet at the top of the pump. A recording meter indicates the total quantity which passes through the primp.
When supplied with a 500-gallon tank the price is £50, including installation charges, or 113 for the pump alone, which is supplied with 10 ft. of delivery hose and has an overall height of 5 ft. 4 ins.
