Abstract
Abstract Apparatus for detaching batches or layers of cotton or similar fibrous material from a bale or stack of such material, wherein a plurality of tines are caused to penetrate into the bale and are then moved away from the bale to detach a part of the same. Air under pressure is issued as jets from the free ends of the tines prior to penetration of the tines into the fibrous material.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
An apparatus for detaching part of a quantity of cotton, or similar fibrous material from the remainder of said quantity of fibrous material, comprising tine carrier means, a plurality of tines supported on said carrier means, actuating means operatively associated with said carrier means for causing said carrier means to move said tines first in a direction to penetrate into said quantity of fibrous material and then in a direction away from said quantity of fibrous material, while penetrating into said quantity of fibrous material, to cause said tines to detach a part of said quantity of fibrous material from the remainder of said quantity of fibrous material, said tines being hollow and having free ends for penetrating said quantity of fibrous material, air supply means operatively associated with said tines for passing air under pressure through said tines to issue as air jets at said free ends of said tines, and control means operatively associated with said air supply means to initiate supply of air to said tines prior to penetration of said quantity of fibrous material by said tines.
Claim 2
Independent Claim
181 words
An apparatus for detaching part of a quantity of cotton, or similar fibrous material from the remainder of said quantity of fibrous material, comprising tine carrier means, a plurality of tines supported on said carrier means, actuating means operatively associated with said carrier means for causing said carrier means to move said tines first in a direction to penetrate into said quantity of fibrous material and then in a direction away from said quantity of fibrous material, while penetrating into said quantity of fibrous material, to cause said tines to detach a part of said quantity of fibrous material from the remainder of said quantity of fibrous material, said tines being hollow and having free ends for penetrating said quantity of fibrous material, air supply means operatively associated with said tines for passing air under pressure through said tines to issue as air jets at said free ends of said tines, and control means operatively associated with said air supply means to initiate supply of air to said tines prior to penetration of said quantity of fibrous material by said tines.
Claim 3
Dependent Claim
23 words
An apparatus according to claim 1 wherein said plurality of said hollow tines are mounted in spaced parallel relationship on said carrier means.
Claim 4
Dependent Claim
27 words
An apparatus according to claim 2, wherein said carrier means is of tubular construction and forms a conduit for supplying air under pressure to said hollow tines.
Claim 5
Dependent Claim
124 words
An apparatus according to claim 1, further including frame means, said carrier means being rotatably mounted in said frame means, said actuating means including lowering and lifting means operatively associated with said frame means for lowering and lifting said frame means towards and away from said quantity of fibrous material, said actuating means further including a pneumatic ram having piston means operatively associated with said carrier means for effecting rotation of said carrier means to move said hollow tines into a position to penetrate the quantity of fibrous material when said frame means is lowered and in a direction to detach a part of said quantity of fibrous material from the remainder of said quantity of fibrous material when said frame means is lifted.
Claim 6
Dependent Claim
57 words
An apparatus according to claim 4, including two tine carriers rotatably mounted on said frame means in such a manner that when said tine carriers are moved in the direction to detach part of said quantity of fibrous material from the remainder of said quantity of fibrous material, said tines of said carriers point towards each other.
Claim 7
Dependent Claim
68 words
An apparatus according to claim 5, wherein said central means includes a feeler device carried by said frame means in such a manner as to be moved into and out of contact with said quantity of fibrous material during the lowering and lifting of said frame means, switch means operated by movement of said feeler device and controlling the supply of air under pressure to said hollow tines.
Claim 8
Dependent Claim
148 words
An apparatus according to claim 1, further including frame means, said actuating means including lowering and lifting means operatively associated with said frame means for lowering and lifting said frame means towards and away from said quantity of fibrous material, two parallel tine carriers mounted on said frame means with the tines of both tine carriers parallel to each other, said tine carriers being movable on said frame means relative to each other, while remaining parallel, and said actuating means further including means to move one of said tine carriers relative to the other to position the tines of both carriers in a common plane for penetrating said quantity of fibrous material and then to move said one tine carrier relative to the other to move said tines apart to detach a part of said quantity of fibrous material from the remainder of said quantity of fibrous material.
Claim 9
Dependent Claim
55 words
An apparatus according to claim 7, wherein the tines of one tine carrier are offset relative to the tines of the other tine carrier, guide members supporting said two tine carriers for movement relative to each other, and a pneumatic ram for moving said one tine carrier relative to the other in said guide members.
