Tecalemit Equipment
A New Five-way Oil Pump, an Adjustable Groupednipple System, a Mobile Air Compressor for Lubrication and Tyre-inflation Duties, also Filters for Petrol and Diesel Oil and an Electric Petrol Pump of Simple Design.
(NE of the first examples of the recently introduced ‘..../Tecalemit five-way lubricating pump was installed on a Maudslay vehicle at Olympia. This set includes a tank fitted to the forward face of-the dashboard, the arm of the pedal being, of course, on the driver's side. .
A filter running the full depth of the tank is situated inside the filler orifice. Tecalemit special central-lubricating oil is recommended for employment in this tank. There are five separate cylinders and pistons delivering lubricant through outlets at the base of the tank. Each exit ,point can be coupled to a distributing valve on the chassis, oil passing thence to calibrated feed plugs situated at each bearing. These plugs pass a pre-determined quantity of oil. This system is applied only to new chassis and is laid out in co-operation with the vehicle manufacturer.
The latest development in the Tecalemit grouped-nipple system is the type which permits adjustment of the quantity of feed to any particular bearing. A master nipple which supplies one bearing is coupled' to others by small brass pipes with banjo-shaped unions delivering lubricant to one point after another. The cone-shaped valve in each nipple is set to deliver the requisite amount of lubricant to its particular bearing. If it be desired to alter the setting the sealing plug is unscrewed and the valve rotated by means of a screwdriver.
In certain garages to-day there are no compressed-air installations ; the need for such plant is growing daily owing to the demand for compressed air for the tyres of large vehicles. Obviously, if compressed air can be made to serve more than the one purpose its use would be more economical. Dearing this in mind, the Tecalemit concern is now marketing a dual-purpose mobile compressor outfit which will inflate tyres and operate an airline Lubrigun or a penetrating-oil spray. This compressor costs 164 158.
A li.p. AC or DC electric motor drives a 21-in. by 2i-in, air-cooled compressor. It has a displacement of 046 4 cubic ft. and will compress air up to 150 lb. per sq. in. Control is effected by an electro-pneumatic switch, which keeps the pressure between 80 lb. awl 120 lb. per sq. in.
Priced at £1 17s. fid. is the Tecalemit petrol filter for commercial vehicles—another recently introduced accessory. It consists of a bracket formed integral with the top plate; this is bolted to the dashboard, or other part of the chassis, and carries the unions for the inlet and outlet pipes. In the detachable bowl is a double metallic gauze of fine mesh.
Now Diesel engines are coming on to the market for commercial-vehicle use, the problem of purification of the fuel oil is bound to arise and the Tecalemit filter, costing £2 10s., is already on the market. It consists of a casing carrying the inlet and outlet unions, also a drain tap in the base. The cover plate is located by four bolts, and the filtering medium consists of three cups of fine gauze.
An ingenious and compact electric fuel pump is One of the latest accessories to be marketed by Tecalemit, Ltd.. Mitre House, Scrubbs Lane, Willesden, N.W.10. It can be bolted to any convenient part of the chassis and embodies a visible petrol filter. It consumes only 1 amp., but will deliver 10 gallons per hour, the feed, of course, being intermittent. The pump is connected to the ignition circuit and fuel is, therefore, only available when the engine requires it. Immediately the engine is switched off the fuel supply is disconnected.
The pump piston is caused to operate in its cylinder by impulses given byan electro-magnet. These impulses are controlled by a magnetic make-and-break device from which sparks have been eliminated by the use of a large condenser. As no fuel is stored in the pump it minimizes the quantity of petrol in proximity to the engine at any time and thus reduces the fire risk. The price of this pump is £3 3s.
