Improvements in Hinges.
Реферат: 10,702. Soss, J. May 22. Hinges.-Relates to a concealed hinge for doors, gates, sashes, the covers of pianos, boxes and cases, and other articles. The face plates c<3>, Figs. 1 and 2, are attached to the swiuging members a, b, in the chambers a<2>, b<2> of which the frame supports c<2> are recessed. The swinging plates are pivoted at d to each swing member, and also to the parts c', the grooves c<6> of which limit their sliding movements in the chambers c<5>. These plates are cut away at e<5> so that they may cross and interlock in their movements. In the modification shown in Fig. 6, each swinging plate is composed of two parts, one part f<2> pivoted at d as in Figs. 1 and 2, and to its similar part at f<7> where they cross, the other part f<3> being pivoted to the part f<2> at f<4> and to the frame c<2> at f<5> by vertical pins f<6>. The hinges may be composed of a number of similar plates placed one above the other providing they are pivoted as in Figs. 1 and 2 at d and in the slot or groove c<6>, or together, as in Fig. 6, at f<4> and f<7> and to the yoke-shaped frames c<2> at d and f<5>.
