    摘要： A brake drum of the heavy-duty type especially for use on trucks and busses where the exterior surface of the cast iron drum has a plurality of helical fins thereon arranged at an angle of 45* to the axis of the drum. The fins are either formed of the same material as and integral with the cast iron brake drum, or the fins may be formed on a shell of a higher heat conductivity than cast iron, such as aluminum, that is cast onto and interlocked with a cast iron sleeve forming the inner friction surface. A third embodiment of drum structure utilizes a plurality of aluminum rings pressed onto the cast iron drum and provided with arcuate generally circumferential fins which terminate at each end in an angularly disposed tip or edge to enhance lateral airflow.

    摘要： Light cast metal outer and inner rings, the opening in the latter being about 8 inches in diameter, said inner ring journaling in said outer ring, for ready coaxial rotation therein. Two vertical horizontally diametrically opposed handles are provided, each being fixed to one of said rings, said handles being simultaneously gripped by the right and left hands in supporting the adapter and rotating said inner ring in said outer ring. Said inner ring supports a camera in its opening. The top of said outer ring rockably supports a flasher unit pivoted thereon on a transverse axis. A cable shutter release is thumb actuatable by a hand gripping one of said handles. A device locking said inner ring against rotation, and while variously rotationally positioned, relative to said outer ring is located for thumb actuation by the other hand while gripping the other handle. A platform adjustably mounted on said inner ring at the bottom of said opening provides a rigid support for a camera variously positioned in said opening.

    摘要： A flat normally horizontal, rectangular camera mounting base is supported manually by a single handle connected at its lower end to the outer end of a leftward extension of the base near the front end of the left edge of said base, said handle normally extending upright but being pivotally adjustable forwardly relative to said extension about a transverse horizontal axis. A flash unit supporting arm extends upwardly from the upper end of the handle at a slight inclination relative thereto to within a short distance of a vertical plane containing the optical axis of a camera mounted on said base. A short horizontal extension extends inwardly from the upper end of said arm, said extension being normal to said vertical plane and bisected thereby. A flash unit mounting screw is provided in said plane on said arm extension and secures to said extension a flasher unit support which is rockable about a horizontal axis normal to said plane. A right-angled adapter bracket is optionally mountable on the base and pivotally supports an elevated right-angled auxiliary camera supporting platform whereby the latter with the camera fixed thereto may be rotated about the focal axis of the camera to any desired angle while taking a picture. To facilitate rapid assembly or disassembly on the camera mounting base of a camera or of the angular adapter bracket, an adapter slug is screwable onto each of the latter and is quickly engageable or disengageable by a novel spring biased clamp on the mounting base. The base of the device has downwardly extending edgewalls which, together with the lateral extension from the base for supporting the handle of the device, engage a flat surface on which the device is placed so as to support the device with the handle in upright position when placed on a table.
