Abstract
Abstract An endless apron conveyor which is used for conveying quarry material, such as crushed rock to or from crushers or other processing equipment. Special anti-friction, double, tapered roller bearings are provided for mounting both the head and foot shafts at opposite ends of the conveyor and in such a manner that the head and foot shafts are interchangeable with one another. Furthermore, the shafts are symmetrical about their center and they are reversible end for end for longer wear life of their sprockets. Special means are provided for mounting the anti-friction, double, tapered roller bearings and their shaft, and these means include an upwardly opening bearing adaptor in which the antifriction bearing assembly is mounted. The adaptor in turn is removably mounted in an upwardly facing, inclined opening in a mounting plate. The anti-friction bearing assembly and other components of the shaft assembly are locked securely in place by shaft end caps and/or drive sprockets. The complete shaft can be easily removed. Furthermore, a modular construction is utilized for installing the rollers which support the heavy duty apron conveyor and this modular construction facilitates the manufacture of conveyors of different lengths and also facilitates replacement and maintenance of the rollers.

Claim 1
Independent Claim
159 words
A heavy duty endless apron conveyor for quarry equipment and the like and comprising, a main frame, a shaft mounted on each of opposite ends of said main frame, an apron type endless conveyor trained around said shafts and having an upper flight; an antifriction bearing assembly mounted on each end of each of said shafts, said bearing assemblies being self-contained, preassembled, pre-set and pre-lubricated, and comprising rollers, inner and outer double tapered races for said rollers, and means for sealing said bearings; and means for mounting each of said assemblies on said main frame and comprising a bearing mounting plate, a bearing adaptor mounted in said plate and having a generally semi-circular and upwardly facing opening which is inclined generally away from the center of said conveyor, said bearing assemblies mounted in said semi-circular openings for placement in and removable from said adaptors through said upwardly facing openings and without removal of said adaptors from said mounting plate.
Claim 2
Dependent Claim
159 words
A heavy duty endless apron conveyor for quarry equipment and the like and comprising, a main frame, a shaft mounted on each of opposite ends of said main frame, an apron type endless conveyor trained around said shafts and having an upper flight; an antifriction bearing assembly mounted on each end of each of said shafts, said bearing assemblies being self-contained, preassembled, pre-set and pre-lubricated, and comprising rollers, inner and outer double tapered races for said rollers, and means for sealing said bearings; and means for mounting each of said assemblies on said main frame and comprising a bearing mounting plate, a bearing adaptor mounted in said plate and having a generally semi-circular and upwardly facing opening which is inclined generally away from the center of said conveyor, said bearing assemblies mounted in said semi-circular openings for placement in and removable from said adaptors through said upwardly facing openings and without removal of said adaptors from said mounting plate.
Claim 3
Dependent Claim
57 words
The conveyor set forth in claim 1 including separate modular sub-frames secured to said main frame along the length thereof, bolt means for detachably securing said sub-frames to said main frame, said modular sub-frames each having a pair of idler rollers mounted therein; the upper flight of said endless conveyor adapted to be supported on said rollers.
Claim 4
Dependent Claim
191 words
A heavy duty endless apron conveyor for quarry equipment and the like and comprising, a main frame, a foot shaft and a head shaft mounted on opposite ends of said main frame, an apron type endless conveyor trained around said head shaft and foot shaft, said conveyor having an upper flight; an anti-friction bearing assembly mounted on each end of each of said shafts, said bearing assemblies being self-contained, pre-assembled, pre-set and pre-lubricated, and comprising rollers, inner and outer double tapered races for said rollers, and means for sealing said bearings; and means for mounting said assemblies on said main frame and comprising a heavy steel bearing mounting plate having a generally upwardly facing cut-away portion, a bearing adaptor mounted in said cut-away portion and having a generally semi-circular and upwardly facing opening which is inclined generally away from the center of said conveyor, said bearing assemblies mounted in said semi-circular opening and held therein by the weight of the endless conveyor trained around said shafts, said assemblies being placed in and removed from said adaptors through said upwardly facing openings and without removal of said adaptors from said mounting plates.
Claim 5
Dependent Claim
191 words
A heavy duty endless apron conveyor for quarry equipment and the like and comprising, a main frame, a foot shaft and a head shaft mounted on opposite ends of said main frame, an apron type endless conveyor trained around said head shaft and foot shaft, said conveyor having an upper flight; an anti-friction bearing assembly mounted on each end of each of said shafts, said bearing assemblies being self-contained, pre-assembled, pre-set and pre-lubricated, and comprising rollers, inner and outer double tapered races for said rollers, and means for sealing said bearings; and means for mounting said assemblies on said main frame and comprising a heavy steel bearing mounting plate having a generally upwardly facing cut-away portion, a bearing adaptor mounted in said cut-away portion and having a generally semi-circular and upwardly facing opening which is inclined generally away from the center of said conveyor, said bearing assemblies mounted in said semi-circular opening and held therein by the weight of the endless conveyor trained around said shafts, said assemblies being placed in and removed from said adaptors through said upwardly facing openings and without removal of said adaptors from said mounting plates.
