Feb. 18, 1925 Hinges; hollow-ware.-Lids of sheet metal are hinged to receptacles by forming one member with spaced pintles projecting at an angle, forming corresponding spaced pivot bearings or sockets on the other member, and assembling these members under pressure so as to cause the pintles to engage with and be straightened out in the bearings or sockets to form a proper hinge connection. The receptacle z is supported by a fixed die c and the lid x by a slidable die b. and between these dies is a die d, Fig. 3, which is movable both horizontally and vertically for first forming the pintles w and bulbs y, Fig. 6, the members w, y engaging during the assembling operation, as shown in II, Fig. 6. The machine in which the dies are operated is shown in Fig. 1. The lid die b is mounted to slide in guides b<1> when operated by a cam e on the shaft f. The part e<1> of the cam causes the shaping parts b<2>, resiliently mounted in the die by springs b<4>, to co-operate with a shaped part d<1> of the die d so that the lid is first split and then shaped to form the pintles w, preferably tubular in crosssection. The movement of the die b also pushes the die d into contact with the fixed body-die c to form the " bulbs " y on the body part z. A cam h on the shaft then acts through a lever and rod arrangement h<1> - - h' against the action of a spring h<4> to lower the slide i carrying the die d. This movement of the slide i raises a plate j through toggle arms j<3> and rods j<1>, and pins k on the plate projecting through slots k<1>, k<2> in the dies lift the parts x, z ready for the assembling operation. The die b is then moved further to the right by the cam part e<2> and the pintles first engage the bulbs or socket parts y and are then straightened out into the plane of the rim of the lid, when the parts are assembled as shown in position II, Fig. 6. It is preferred that the portion of the lid between the pintles is beaded to engage the groove z<1> between the bulbs y. This may be effected by a portion z<2> on the lid die co-operating with the groove z<1> as the parts are being assembled. The shaft f of the machine is provided with a brake g comprising pivoted shoes g surrounding a drum g<2> on the shaft and having a spring g<3> on a bolt g' with adjusting means g<5>.
