Filed: 1936-12-05
Abstract: 470,447. Relief devices for machinery. ERICHSEN, A. M. Dec. 5, 1936, No. 33409. [Class 69 (ii)] [Also in Groups II, XXII, and XXIV] A pressure relieving or regulating device for rolling-mills, presses, and like machines subjected to high pressure and in which a pressure medium acts as a safety element, is provided with a medium which is non fluid and is a homogeneous mass which flows only under considerable pressure. Such medium may be rubber rubber dough, plasticine, gelatine or other like elastic or plastic non-liquid masses. A plunger plate 3 adapted to take the bearing of the rolling mill is disposed within a casing 1 having a mass of plastic matter 2 therein. At a predetermined pressure the mass breaks a diaphragm 8 and flows out thus relieving the pressure. Such pressure may also be reduced by the use of a valve 10 provided at the other end of the lower passage. A pressure gauge may also be fitted to communicate with the plastic mass. Instead of a diaphragm 8, a plug 15 held in position by a spring 14 may be adopted, and the pressure of the spring can be regulated by a plug 37 which can be set by the screw nut 42. In order that the mass may be used again the outlet may communicate through a passage 27 with a distensible chamber 28, which in turn is reconnected by the pipe line 29 and non-return valve 31 with the chamber. Instead of flexible walls for the chamber 28, there may be rigid with one of them movable against spring restraint. In place of one plastic mass only it may be desirable to use a ring-like rubber member 32 at the chamfered rim 33 of the piston member 3, the remainder of the mass 2 being of a more plastic character.
