They went lurching down the curving grade into the hollow, and struck the patch of sand that had worn out the vocabularies of more eloquent men than he. Robert Grant Burns fed more gas, and the engine kicked and groaned, and sent the wheels burrowing like moles to where the sand was deepest. Axles under, they stuck fast.
Q. Will you describe the structure of the framework on which the boiler and its attachments rest, and in which the wheels are set? A. The framework or framing consists of a rectangular structure of plate iron circumscribing the boiler, with projecting lugs or arms for the reception of the axles of the wheels.
The cylinders are outside, 17½ in. diameter and 26 in. stroke, with single driving wheels 7 ft. 5 in. diameter, the leading and trailing wheels being 3 ft. 8 in. diameter. The total wheel base is 15 ft. 9 in., and the frames are double, giving outside bearings to the leading and trailing axles, and inside bearings to the driving axle.
A week after the dispatch of the citation, the wagon of the executioner of Zeb rattled over the stones of the market-place of Kassa. It was a black vehicle, with red wheels and axles, on which the somber company, like a troupe of itinerant comedians, brought with them all the requisites of their terrible stage. Mounted drabants and musketeers escorted them before and behind.
When they apply the brake to a train, the train comes to a stop; but what becomes of the motion which it had previously possessed? It is transformed into heat, and the brake becomes hot. Why do they grease the axles of the wheels? To prevent their heating, because this heat would be generated by the motion which is thus lost by transformation." "Yes, I understand," replied Michel, "perfectly.
Morgans then spoke of the high reputation of sheet mill rolls and wheel axle boxes made in Bristol. Of the latter in combination with wrought iron wheels and steeled axles, the local wagon works company are exporting large numbers.
Friction clutches are used by which the driving-shaft and the axles can be connected or disconnected at the will of the driver, so that the vehicle can stand while the motor is running; friction clutches are used also to throw in gears of different sizes to increase or decrease the speed of the vehicle, as well as to drive backward.
There is nothing like castor-oil for these patent axles. You ought to be off in an hour.
"Ah," said he, "those things won't last long. That oil-cloth covering for your luggage will be torn to pieces in a few days by the postillions climbing upon it. Then they hold on to your seat and rip the cloth lining with their long nails; besides, the rope reins wear the leather off your dashboard, and you will be lucky if your wheels and axles don't snap on the rough roads."
Eventually the chain was laid aside, and the front and hind wheels were united by rods on the outside, instead of by rods and crank axles inside, as specified in the original patent. This expedient completely answered the purpose required, without involving any expensive or difficult workmanship.
