ABSTRACT:
An electromagnetically actuated drum type brake embodying an improved support for the actuating magnet. The magnet is supported by a lever and when energized effects pivotal movement of the lever to actuate the brake. The support between the lever and magnet permits some floating movement of the magnet so as to accommodate for surface irregularities and relative movement between the magnet and the lever as is necessary to effect brake actuation. The support, however, restricts the degree of relative movement between the magnet and lever to acceptable values while transmitting the actuating force from the magnet to the lever. The support comprises an integral tab formed at the outer end of the lever which extends into an aperture in the magnet with sufficient clearance to permit limited movement in several directions. Rotary movement is, however, not restricted by this connection. The magnet housing also has an integral, outstanding tab that extends through an aperture in the lever to restrict the degree of pivotal movement and transmit the actuating force.
