Claims

1. AN ELECTROMAGNETIC DISC BRAKE FOR AN ELECTROMAGNETIC MOTOR HAVING A DISC WITH THE MOTOR SHAFT, COMPRISING:

(A) A SUPPORT SECURED TO SAID MOTOR;

(B) A HOUSING HAVING THEREIN AN ELECTROMAGNET ADAPTED TO BE ENERGISED WHEN SAID MOTOR IS FED WITH CURRENT, SAID MAGNET HAVING A YOKE PROVIDED WITH SPRINGS AND AN AIR GAP OF A GIVEN DIMENSION;

(C) A PAIR OF SELF-LUBRICATING RINGS CARRIED BY THE SUPPORT;

(D) A PAIR OF JAWS EACH CARRYING A BRAKE LINING ADAPTED TO CONTACT SAID DISC AND BRAKE THE SAME;

THE FIRST OF SAID JAWS BEING SECURED AT ONE END OF A ROD AND TO A GUIDE SLIDINGLY MOUNTED IN SAID RINGS;

THE SECOND OF SAID JAW BEING ALSO SECURED TO SAID GUIDE AND NORMALLY SPACED APART FROM SAID YOKE BY SAID SPRINGS, SAID SECOND JAW BEING ATTRACTED BY SAID ELECTROMAGNET WHEN THE SAME IS ENERGISED WHEREBY TO GRIP SAID DISC TOGETHER WITH SAID FIRST JAW;

(E) A PLURALITY OF WEAR WASHERS MOUNTED ON SAID ROD AND SEPARATING SAID GUIDE FROM SAID YOKE;

(F) A PAIR OF BARS PASSING THE SAID HOUSING, EACH HAVING SPRINGS URGING SAID HOUSING AND SAID YOKE TOWARD SAID SUPPORT, SAID BARS HAVING STOPS THEREON FOR LIMITING SAID AIR GAPS AS A FUNCTION OF THE WEAR OF SAID BRAKE LININGS;

AND, (G) MEANS FOR ADJUSTING THE TENSION OF SAID SPRINGS URGING SAID SECOND JAW AWAY FROM SAID YOKE AND THEREBY ADJUSTING THE DIMENSION OF SAID AIR GAP.
