A transmissionless driving arrangement for rotary drums in which at least one support for the drum is constituted by a slide ring which is carried by stationary slideshoes or rollers and surrounds the drum to which it is attached, the rotor and the stator of an electric motor which is utilized for rotatably driving the drum surrounding the body of the drum.

A drum shaped container equipped with a tapered base plate having an inverted U-shaped channel extending diametrically through the bottom surface thereof, and a retrainer strap provided with adjustment holes in one end thereof and having a retainer spring resiliently connecting the ends of the strap together, the strap adapted to be passed about four of the drums with the channels in the base plate of the front pair of drums being longitudinally aligned with the channels in the back pair of drum...

The end closure comprising a peripheral cylindrical wall which is fitted in the cylindrical body and a substantially planar lateral wall axially offset relative to the free outer edge of the peripheral wall. The peripheral wall of the end closure is connected to the lateral wall by a small rounded channel followed radially inwardly by a connecting fillet. The lateral wall has at least one inverted U-shaped stiffening channel much larger than the rounded channel and extending into the cylindrical...

This invention relates to a foot-operated Bowden type cable mechanism which is operatively associated with a padded damping plate whose incidence with the underside of a timpano membrane, for example, terminates its vibration. If the device of the invention is actuated prior to the delivery of an exciting blow, operation is as a muffler or mute. In an alternate embodiment, an electromechanical actuator is mounted so as to allow the silent and hand-free muffling or silencing of a timpano. Typical...

This invention relates to a brake mechanism for winch drums wherein the brake is normally applied and two independent brake release devices are provided to release the drum for rotation. The primary brake release completely frees the drum for "free spooling" rotation and the secondary brake release partially releases the brake restraining elements but maintains a relatively heavy braking drag on the drum to restrain the paying out of the cable from the drum except when subjected to a substantial...

A method and apparatus for closing the ends of plastic bung or stopper drums. The apparatus comprises an end closing coupling for a bung drum composed of plastic material wherein the upper edge of the body of the drum has a circumferential bordure including an inwardly projecting groove and an inwardly bent edge. An end closure for the bung drum is fashioned with a circumferential marginal bead having grooves operable to receive the inwardly projecting groove and inwardly bent edge of the drum b...

A bracket for mounting drums of the tom-tom type consists of an arcuate member having inwardly directed flanges which have apertures to mount to the pre-existing lugs of the drum. Vibration absorbing grommets are provided in the flanges in order to provide both a resilient support as well as to cut down vibration transfer into the drum stand to which the bracket is mounted. The bracket is essentially semi-circular and provides its main support at diametrically opposed points of the drum and util...

A rocker cam for holding a beater head and a resilient belt or strap for operationally connecting the rocker cam to an inclined foot pedal are coupled to each other via meshing engagement by cooperating indentations formed on mating surfaces of the two members and tensile strength of the belt or strap is remarkably enhanced by fortifying members such as steel wires or glass fibers longitudinally embedded in the belt or strap. Stress concentration on a set screw for fixing the belt or strap to th...

An arrangement is disclosed for supporting a rotary drum such as a rotary kiln resting upon a foundation. The support arrangement includes a weigh beam positioned in a horizontal plane and pivotally supported on the foundation. At least two carrying beams are poitioned in a generally horizontal plane adjacent said weigh beam and each of the carrying beams are pivotally mounted at one end thereof to the foundation and flexibly supported at another end thereof by the weigh beam. A roller for rotat...

A device for rotatably supporting a drum or reel of the type on which cable is wound. The vertical flanges of respective angle members are spaced apart to receive therebetween the circular end flange of the cable drum. The drum flange is supported on roller bearings mounted between the angle members. An arcuate cutout is formed in the vertical flange of one angle in order to accommodate the outer layer of cable when the drum is full or nearly full. The invention also provides a toggle type mecha...
