A new method of securing carriage wheels on to their axles has been invented by Guy Davis, of Syracuse, N. Y., who has taken mea sures to secure a patent. It consists in fitting two springs having catches at their ends around the inner cireumterence of the rimer end of the axle box, which, where the wheel is placed on, is made tight by means of a dove-tail wedge driven into the hub. The grooves for receiving the springs are made of a suitable depth to allow of their being pressed down, for the purpose of disconnecting the catchss from the axle, when the wheels are required to be taken off or put on. By this method of securing the wheels on the axle, no screws are required, so that they can be put on or removed with the utmost dispatch. It is likewise very cheap.
