Arousing Interest in a Transport Operation by Means of a Working Model.
MODELS are not always suitable for display at such a Show as the recent Commercial Motor Exhibition, but, occasionally, one comes across a model which, whilst adequately demonstrating some feature of transport, is of particular interest in itself.
A good many people stopped and were intensely interested in the model of a tipping wagon in operation on the stand of the Vulcan Motor and Engineerino. Co. (1906), Ltd., but those who had the privilege of being shown all the details of operating the model found a considerable amount of added interest in it.
The model was devised by Mr. Edwards, of the well-known firm of tipping gear specialists, Bromilow and Edwards, Ltd., of Bark Street, Bolton. Mr. Edwards is really a genius at model design and manufacture, and he has made a number of ingenious pieces of mechanism, one point being that the whole of the details are made with his own hands.
The particular model to which we refer shows a Vulean tipping wagon moving along a short length of runway, receiving a small load of stone from a chute, carrying it to the other end of the runway and there tipping it to one side, the body then recovering its normal position and the-lorry returning, in reverse, to the delivery chute.
Every detail of the lorry is true to fact, except, of course, that it has no driving mechanism, but, outwardly, it closely resembles the original. Some of the details are really beautiful, as, for instance, the radiator, which consists of fine brass rod with gills turned on it, and, as will be seen from our illustration, the vehicle is perfectly equipped with starting handle, number plates, wings, aide lamps, horn, and even right down to the licence plate, shoVeing that the vehicle is fully licensed to the end of the year !
A .sniall electric motor through a chain hauls the vehicle backwards atl forwards along the runway, and when the lorry is at the forward end of the
runway a small striker protruding just above the surface of the " road " travels forward and operates all oil pump on the' model lorry which, through a ram, tilts the tipping body to the left side, the hinged side of the lorry opening under the weight of the load, a cam action, operating through a lever, closing the aide as the body returns to the hori2ontal. The stones fall into a receiver and thence on to a continuously running belt, which returns them to the rear and drops them into a lift. Whilst the vehicle is running backwards, this lift is raised to the level of the delivery chute, but just before it reaches the chute the front door of the lift halts so as to allow the load to be shot out, and on reaching the correct level the lift tilts and delivers the load through the chute.
The " roadway " is lighted at night by four electric lamps mounted on standards, and it is " protected " throughout its length and at the forward end by chains carried on posts, every post being beautifully turned and finished.
The operation is always carried out in a very cleanly manner and without a falter, and Mr. Edwards deserves our congratulations upon his ingenuity, Patience and skill in its design and construction.
