181 Roller conveyor system having speed control US840208 1977-10-07 US4168771A 1979-09-25 Bert Krivec
A free wheeling tire having the ability to resist increased rotational speed under load is comprised of a hub portion, rim portion, and a multiplicity of flexure members defining voids extending continuously from one side of the tire to another. Deleterious heat generated during operation is successfully dissipated through the increased surface area provided by the voids and by the nature of geometrical element configuration. The tires are placed in a gravity roller conveyor in arrays where each array may have different speed control characteristics permitting variations in speeds of objects as they move from one array to another.
182 Braking device US580379 1975-05-23 US4000796A 1977-01-04 Frederick Arthur Bolton; James Louis Eckebrecht
A braking device for retarding and controlling the speed of moving objects such as cartons, pallets and the like, travelling down an inclined roller conveyor system. The device comprises a primary roll journalled in a housing and having a peripheral surface actuable by a said moving object and a secondary roll journalled within the housing actuable by the primary roll. The secondary roll is loosely journalled in a bracket pivotally mounted on an axle coaxial with the primary roll and is biased by an adjustable pressure plate having a bevelled portion at one end to an at-rest position in proximity to the primary roll. Rotation of the primary roll under the weight of an object travelling thereon rotates the secondary roll by frictional interengagement against the bias of the pressure plate whereby the secondary roll becomes wedged between said primary roll and the pressure plate bevelled portion for retarding the rotation of the primary roll.
183 Skatewheel conveyor pallet US564375 1975-04-02 US3971314A 1976-07-27 Theodor Max Box
This invention relates to pallets employed in materials handling on wheel conveyors, also known as skate or skatewheel conveyors, and more particularly to a pallet which is self-guiding along the conveyor.
184 Live roller conveyor US48335874 1974-06-26 US3900097A 1975-08-19 DE COURCY ROWLAND J J
A roller conveyor of the kind in which rollers are free to turn between side members and are driven by means of an endless driving belt or the like which engages the undersides of the rollers is so constructed that at least one group of rollers together with the supporting side members form a unit mounted for movement in a generally horizontal plane in a direction opposite to the direction of conveying against a resilient biasing force, movement in this direction in excess of a predetermined amount serving to actuate a control member to operate an independently powered mechanism for separating the rollers of the unit from the driving belt or the like so that the frictional drag is completely removed. The independently powered mechanism is released again when the control member is released and a braking pad is provided to engage a few rollers at the leading end of the unit when the rollers are separated from the driving belt or the like. The independently powered mechanism preferably lifts the unit as a whole to separate the rollers from the driving belt and may be pneumatically operated, the control member controlling the flow of compressed air to the mechanism.
185 Conveyor stop US35811873 1973-05-07 US3891073A 1975-06-24 COLEMAN BESTOR P; MCCONNELL KENNEDY
A load spacing mechanism for a conveyor includes an actuating member and a stop member, the latter of which is movable into a load stop position when the actuating member is depressed by the lead load. The stop member is spring urged into the load stop position whereby, if the lead load has not yet cleared the stop member, the stop member will remain in its retracted position until cleared by the load at which time the stop member will immediately move into the stop position to arrest movement of the next successive load.
186 Silicone putty retarder US40091073 1973-09-26 US3871501A 1975-03-18 KORNYLAK ANDREW T
A retarder roller for limiting the speed of a free runing load on an inclined conveyor. The roller comprises a stator and a rotor rotatably mounted on the stator and forming a housing for the stator. The housing is filled with silicone putty. The stator and housing are provided with vanes for cutting through and displacing the putty as the housing is rotated.
187 Process for the manufacture of steroid tropones US84002669 1969-07-08 US3810916A 1974-05-14 ANNER G; WIELAND P

188 Article stop for conveyors US3796293D 1971-08-19 US3796293A 1974-03-12 WARMANN B
A device for arresting movement of an article on a roller conveyor consists of a bar projecting outwardly from a cylindrical sleeve rotatably mounted on a shaft which in turn is rotatably supported on the conveyor between and parallel to an adjacent pair of rollers. Rotation of the sleeve on the shaft is resiliently opposed by a cluster of flexible rods mounted within the sleeve and extending parallel to the shaft, the rod ends being inserted in sockets of a pair of collars on the shaft, one collar being secured to the sleeve and the other to the shaft. A counterweight on the shaft urges the device to an obstructing position in which the bar extends into the path of movement of an article on the conveyor rollers, and a releasable latch prevents movement of the shaft from this position so that engagement of the bar by an oncoming article results in movement of the bar and sleeve being resiliently opposed by the flexible rods to absorb the momentum of the article.
189 Brake device US3648815D 1970-06-15 US3648815A 1972-03-14 WOCHNER JOSEPH J
Wheel structure having an outer tire region of flexible material hollowed to define an annular dead end fluid passage containing entrapped fluid.

A braking device for gravity roller conveyors is disclosed in which a flexible band is disposed against certain conveyor rollers to apply a self-energizing frictional braking force upon being tensioned by a powered cyclical tensioner for tensioning and releasing the band at predetermined periodical intervals.
