Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
A worm conveyor, especially for conveying liquid and mud, which includes: a shaft means capable of being rotatably driven and hollow on at least one end thereof, worm means on said shaft means, trough means partially surrounding said worm means peripherally, one end of said worm means being rotatably journalled on said shaft means directly on said trough means, and driving means at least in part fitted compactly complementary into said trough means and drivingly connected to the other end of said worm means and rigidly supported by said trough means so as to thereby indirectly journal said other end of said worm means on said trough means.
Claim 2
Dependent Claim
108 words
A worm conveyor, especially for conveying liquid and mud, which includes: a shaft means capable of being rotatably driven and hollow on at least one end thereof, worm means on said shaft means, trough means partially surrounding said worm means peripherally, one end of said worm means being rotatably journalled on said shaft means directly on said trough means, and driving means at least in part fitted compactly complementary into said trough means and drivingly connected to the other end of said worm means and rigidly supported by said trough means so as to thereby indirectly journal said other end of said worm means on said trough means.
Claim 3
Dependent Claim
50 words
A worm conveyor according to claim 1, in which said driving means includes geared driving means with a bearing bushing connected to said other end of said worm means and with a bearing stud for rotatably supporting said bearing bushing, said bearing stud being non-rotatably connected to said trough means.
Claim 4
Dependent Claim
38 words
A worm conveyor according to claim 2, in which said driving means includes electric motor means having stationary winding means connected to extension of said bearing stud and also having rotary winding means connected to said bearing bushing.
Claim 5
Dependent Claim
31 words
A worm conveyor according to claim 1, which includes adjusting means associated with said trough means and worm means for adjusting said trough means and said worm means as to height.
Claim 6
Dependent Claim
71 words
A worm conveyor according to claim 4, in which said adjusting means includes spindle means pivotally connected to one end of said trough means and operable selectively to lift and lower said one end of said trough means, said conveyor also including supporting means tiltably supporting the other end of said trough means and defining the pivot axis about which said trough means is tiltable by actuation of said spindle means.
Claim 7
Dependent Claim
16 words
A worm conveyor according to claim 5, in which said supporting means forms a knife-edge bearing.
Claim 8
Dependent Claim
92 words
A worm conveyor according to claim 1, which includes bearing bushing means connected to said other end of said worm means, and in which said driving means includes motor means and transmission means, said transmission means at least being located within said bearing bushing means, and said motor means being located outside said bearing bushing means and said trough means, said conveyor also including said shaft means drivingly interconnecting said motor means and said transmission means, and hollow bearing stud means surrounding said shaft means and rotatably journalling said bearing bushing means.
Claim 9
Dependent Claim
20 words
A worm conveyor according to claim 7, which includes coupling means interposed between said shaft means and said motor means.
Claim 10
Dependent Claim
32 words
A worm conveyor according to claim 7, in which said transmission means has flanged connection to said motor means and with exception of said stud means fits compactly in said bushing means.
