Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
111 words
An apparatus to assure against formation of bridges of fibrous silo material in a silo container having a substantially tubular upright portion with a bottom, which includes: multiple friction brake means with lateral marginal areas connected to the inner wall surface of said tubular portions so as to form obtuse angles therewith, and friction surface means inclined downwardly on each friction brake means, said lateral marginal areas extending along substantially the entire height of said friction surface means of respective friction brake means, said lateral marginal areas of adjoining friction brake means where directed toward each other extending in horizontal section in a direction toward the middle of the silo container.
Claim 2
Independent Claim
111 words
An apparatus to assure against formation of bridges of fibrous silo material in a silo container having a substantially tubular upright portion with a bottom, which includes: multiple friction brake means with lateral marginal areas connected to the inner wall surface of said tubular portions so as to form obtuse angles therewith, and friction surface means inclined downwardly on each friction brake means, said lateral marginal areas extending along substantially the entire height of said friction surface means of respective friction brake means, said lateral marginal areas of adjoining friction brake means where directed toward each other extending in horizontal section in a direction toward the middle of the silo container.
Claim 3
Dependent Claim
38 words
An apparatus in a silo container according to claim 1, in which the lateral marginal areas of said friction brake means when seen in a horizontal section converge in the direction toward the central axis of said container.
Claim 4
Dependent Claim
36 words
An apparatus in a silo container according to claim 2, in which the lateral marginal areas of said friction brake means and symmetrically located with regard to the vertical central plane of said friction brake means.
Claim 5
Dependent Claim
52 words
An apparatus in a silo container according to claim 1, in which said friction brake means includes more than two friction brake bodies at substantially equal level, those lateral marginal areas which face toward each other when viewed in horizontal section diverging in the direction toward the central axis of the container.
Claim 6
Dependent Claim
27 words
An apparatus in a silo container according to claim 4, in which those lateral marginal areas which face each other form an acute angle with each other.
Claim 7
Dependent Claim
18 words
An apparatus in a silo container according to claim 1, in which said lateral marginal areas are plane.
Claim 8
Dependent Claim
22 words
An apparatus in a silo container according to claim 1, in which the inner wall surface of the silo container is cylindrical.
Claim 9
Dependent Claim
32 words
An apparatus in a silo container according to claim 1, in which the lateral marginal areas of said friction brake means merge with the central region thereof while forming therewith obtuse angles.
Claim 10
Dependent Claim
45 words
An apparatus in a silo container according to claim 1, in which the brake surface area of each of said friction brake means is formed by two surface sections which when viewed in a horizontal section intersect each other so as to form a V.
Claim 11
Dependent Claim
25 words
An apparatus in a silo container according to claim 1, in which the brake surface area of each of said friction brake means is conical.
Claim 12
Dependent Claim
29 words
An apparatus in a silo container according to claim 1, in which the brake surface area of each of said friction brake means is of a pyramidal segmental shape.
Claim 13
Dependent Claim
39 words
An apparatus in a silo container according to claim 1, in which the central axis of the brake surface of each of said friction brake means is in upward direction inclined toward the central axis of the silo container.
Claim 14
Dependent Claim
37 words
An apparatus in a silo container according to claim 12, in which the central axis of the brake surface intersects the inner surface of the container mantle surface at the upper tip of the brake surface area.
Claim 15
Dependent Claim
35 words
An apparatus in a silo container according to claim 1, in which the angle defined by the two marginal areas of the friction brake means exceed the arc angle of the pertaining brake surface area.
Claim 16
Dependent Claim
32 words
An apparatus in a silo conTainer according to claim 1, in which the brake surface area of each friction brake means is downwardly inclined toward the central axis of the silo container.
Claim 17
Dependent Claim
38 words
An apparatus in a silo container according to claim 1, in which at least one marginal region of said friction brake means when considered in view is of triangular shape with the tip of the triangle pointing upwardly.
Claim 18
Dependent Claim
33 words
An apparatus in a silo container according to claim 1, in which said friction brake means includes a plurality of friction brakes laterally spaced from each other and respectively arranged at different levels.
Claim 19
Dependent Claim
59 words
An apparatus in a silo container according to claim 1, in which said bottom is provided with passage means, and which includes conveyor means arranged below the bottom of the silo container and communicating through said passage means with the interior of said container, at least one friction brake means being located vertically above each of said conveyor means.
