The cart here described is 6 ft. long by 4ft. 6 in. wide, and may be used for carrying furniture. As the wheels are to run underneath the bed of the cart, the distance between the springs must be less than is customary in ordinary work. Set out a full-size plan of the cart, mark in the position of the wheels, so that the stock hoop does not project beyond the side of the cart, and mark in the position of the springs or stays to which the axle is fixed, as summers have to be framed in to fix these to. For the outside framing, two rails 2 in. wide by 1 3/4 in. deep, front and hind bars 2 in. wide by 2 1/2 in. deep, are framed together square and true, and flush oh top. This framing is boxed out on the top inner edge, 3/4 in. on by 6/8 in. deep, to take the boards to form the floor. At such a distance in from the outside as the springs will come, frame in two summers 2 1/4 in. wide, thick enough to be level with the boxing out on top, and flush with the cross-bars at the bottom. If the cart is to have two handles, these are bolted to the summers; if there is to be only one handle, it is fixed in the centre underneath the bottom to both the hind and front bars.
Next bolt on the springs or stays; if springs are used, see that the scroll irons and springs combined are of such a depth that the wheel is 3 1/2 in. clear at the top to the under side of the frame; if iron stays are used, 1 in. clearance will suffice. Having bored on the springs and fixed the axle, put in the bottom boards of red deal 3/4 in. thick, the grain of which should run from side to side. To protect the outer corners of the frame, iron corner-plates should be fixed round, about 6 in. each way. The wheels should be about 2 ft. 9 in. high; this would bring the top of the cart about 3ft. 3 in. from the ground line. To make the cart more useful, portable boards may be fitted round by placing small iron staples on the outside of the frame, and irons on the boards, the irons being so made as to slip into the staples.
