Реферат: 24,080. Barratt, A. J. Oct. 22. Barrel and cylindrical hinges for the lids of tea and coffee pots, biscuit jars, jugs, &c. are made from flat blanks a<2> cut from a sheet a of uniform thickness and subjected to die pressure to shape it to the required crosssection as shown in Fig. 3. The edge c<2> is then trimmed off, and the knuckle edge d, Fig. 5, partly milled into shape. The knuckles are formed by first cutting the gaps f by one or a number of spaced milling-cutters e, Fig. 7, and secondly by deepening the bottoms f<2> of the gaps by a cutting-tool h, Fig. 11, mounted upon an oscillating holder h<2>, the axis of which is concentric with that of the hinge barrels, so that, when the flaps are connected by a hinge-pin, the barrels of one flap accurately fit the gaps of the other. The projections j, Fig. 12, are finally removed by facing-cutters to form the finished hinge shown in Fig. 13.
Method of manufacture of the component with the cross section in the form of the hat
