Abstract
Abstract The conveying apparatus has a plurality of reciprocating, rotatable scraper elements for successively pushing particles on a stationary support frame. Forward movement of a reciprocating driving element rotates the plurality of scraper elements into an operating position and carries them in a forward direction along the conveyor. Change of direction in the movement of the driving element rotates the scraper elements into a non-operative position and further rearward movement of the driving element carries the plurality of scraper elements to their original position whereupon the aforementioned cycle is repeated to move the particles along the conveyor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
271 words
Apparatus for conveying particulate material from a receiving station to a depositing station, comprising; a frame for retaining said particulate material, means mounted to said frame for reciprocating along the longitudinal axis of said frame, a number of elements mounted within said frame to reciprocate with said reciprocating means for successively moving the material along said longitudinal axis, each of said elements is in a first position to contact said material during forward movement of said reciprocating means and in a second position out of contact with said material during backward movement of said reciprocating means, means for driving said means for reciprocating, a housing dividing said frame along its longitudinal axis for distributing said material to said elements, means for connecting said reciprocating means to said housing and to each of said elements, said connecting means reciprocating along said longitudinal axis with said reciprocating means and moving said elements out of contact with said material as said reciprocating means changes from a forward to a rearward movement and moving said elements in contact with said material as said reciprocating means changes from a rearward to a forward movement, said reciprocating means includes elongated apertures, said housing includes shafts rotatably mounted within said housing transversely to said longitudinal axis, and said means for connecting each of said elements to said means for reciprocating includes means slidable within a respective elongated aperture and fixed to a respective one of said shAfts whereby said slidable means moves in said elongated aperture only during the change of direction of said reciprocating means to rotate said shaft to cause said movements of said scraper elements.
Claim 2
Dependent Claim

Apparatus for conveying particulate material from a receiving station to a depositing station, comprising; a frame for retaining said particulate material, means mounted to said frame for reciprocating along the longitudinal axis of said frame, a number of elements mounted within said frame to reciprocate with said reciprocating means for successively moving the material along said longitudinal axis, each of said elements is in a first position to contact said material during forward movement of said reciprocating means and in a second position out of contact with said material during backward movement of said reciprocating means, means for driving said means for reciprocating, a housing dividing said frame along its longitudinal axis for distributing said material to said elements, means for connecting said reciprocating means to said housing and to each of said elements, said connecting means reciprocating along said longitudinal axis with said reciprocating means and moving said elements out of contact with said material as said reciprocating means changes from a forward to a rearward movement and moving said elements in contact with said material as said reciprocating means changes from a rearward to a forward movement, said reciprocating means includes elongated apertures, said housing includes shafts rotatably mounted within said housing transversely to said longitudinal axis, and said means for connecting each of said elements to said means for reciprocating includes means slidable within a respective elongated aperture and fixed to a respective one of said shAfts whereby said slidable means moves in said elongated aperture only during the change of direction of said reciprocating means to rotate said shaft to cause said movements of said scraper elements.
Claim 3
Dependent Claim
31 words
Apparatus as in claim 1 wherein each of said shafts protrude on either side of said housing and a scraper element is mounted to each end of each of said shafts.
Claim 4
Dependent Claim
33 words
Apparatus as in claim 2, wherein each of said elements has a shape substantially conforming to the inner surface of said frame to provide a narrow clearance between its surfaces adjacent said frame.
Claim 5
Dependent Claim
41 words
Apparatus as in claim 1 further comprising a pair of transversely spaced guide members extending along said longitudinal axis and each guide member having a longitudinally extending groove, and members fixed to said housing and movable within each of said grooves.
Claim 6
Dependent Claim
26 words
Apparatus as in claim 4, further comprising means for reducing the friction between each of said longitudinally extending grooves and said members fixed to said housing.
Claim 7
Dependent Claim
86 words
Apparatus as in claim 5, wherein said friction reducing means includes a pair of additional guide members each having an additional groove and each additional groove is positioned substantially in line with a respective groove of said guide members, and means for mounting each of said additional guide members so that said members fixed to said housing slide only along a surface of said additional groove, and the length of each of said additional grooves is substantially less than the length of each of said grooves.
