Warp beam

Claim 2

A warp beam comprising at least two telescopically engaging elongated rigid tubular parts disposed in overlapping relation to define a common area of overlap and an elongated cylindrical surface to receive warp threads thereon; a flange attached to each of the parts at opposite ends of the thread receiving surface; and clamping means mounted within the innermost part of said parts for pressing said innermost part radially outwardly against the outermost part within said area of overlap, said clamping means being located between the flanges.

Claim 3

A warp beam comprising at least two telescopically engaging tubular parts disposed in overlapping relation to define a common area of overlap; and clamping means mounted within the innermost part of said parts for pressing said innermost part radially outwardly against the outermost part within said area of overlap, said clamping means including a triangularly shaped radially disposed plate within said area of overlap, means mounting said plate for pivotal movement, and means for pivotally moving said plate to expand the innermost part of said parts radially against the outermost part of said parts.

Claim 4

A warp beam comprising at least two telescopically engaging tubular parts disposed in overlapping relation to define a common area of overlap; and clamping means mounted within the innermost part of said parts for pressing said innermost part radially outwardly against the outermost part within said area of overlap, said clamping means including a triangularly shaped radially disposed plate within said area of overlap, means mounting said plate for pivotal movement, and means for pivotally moving said plate to expand the innermost part of said parts radially against the outermost part of said parts.

Claim 5

A warp beam as set forth in claim 1 wherein said clamping means includes a wedge mounted on the innermost part of said parts, a substantially radially disposed plate having a wedge-like surface bearing on said wedge, and a spindle rotatably mounted within said parts and passing through said plate in threaded relation to move said plate relative to said wedge to selectively tighten said plate against said wedge upon rotation of said spindle.

Claim 6

A warp beam as set forth in claim 3 which further comprises a bearing flange secured to one end of said innermost part, said flange having a recess therein; and wherein said spindle has a terminal portion mounted within said flange and in said recess.

Claim 7

A warp beam as set forth in claim 3 wherein said plate is a triangularly shaped plate.

Claim 8

A warp beam as set forth in claim 5 which further includes a pair of abutments in said innermost part mounting two vertices of said plate thereon.

Claim 9

A warp beam as set forth in claim 1 wherein said innermost part extends beyond said outermost part and which further comprises a plurality of shell-like shims over said innermost part, said shims having the same outer dimensions as said outermost part to form a smooth continuous outer surface with said outermost part.

Claim 10

A warp beam comprising at least two telescopically engaging parts disposed in overlapping relation to define a common area of overlap; and clamping means pressing said parts together radially within said area of overlap, said clamping means including a wedge mounted on said innermost part, a substantially radially disposed plate having a wedge-like surface bearing on said wedge, a bearing flange secured to one end of said innermost part and having a recess therein, and a spindle rotatably mounted within said parts and passing through said plate in threaded relation to move said plate relative to said wedge to selectively tighten said plate against said wedge upon rotation of said spindle, said spindle having a terminal portion mounted within said flange and in said recess.

Claim 11

A warp beam comprising at least two telescopically engaging parts disposed in overlapping relation to define a common area of overlap; and clamping means pressing said parts together radially within said area of overlap, said clamping means including a wedge mounted on said innermost part, a substantially radially disposed plate having a wedge-like surface bearing on said wedge, a bearing flange secured to one end of said innermost part and having a recess therein, and a spindle rotatably mounted within said parts and passing through said plate in threaded relation to move said plate relative to said wedge to selectively tighten said plate against said wedge upon rotation of said spindle, said spindle having a terminal portion mounted within said flange and in said recess.

Claim 12

A warp beam comprising at least two telescopically engaging parts disposed in overlapping relation to define a common area of overlap with the innermost part extending beyond the outermost part; clamping means pressing said parts together radially within said area of overlap; and a plurality of shell-like shims over said innermost part and having the same outer dimensions as said outermost part to form a smooth continuous outer surface with said outermost part.

Claim 13

A warp beam comprising at least two telescopically engaging parts disposed in overlapping relation to define a common area of overlap with the innermost part extending beyond the outermost part; clamping means pressing said parts together radially within said area of overlap; and a plurality of shell-like shims over said innermost part and having the same outer dimensions as said outermost part to form a smooth continuous outer surface with said outermost part.

Claim 14

A warp beam comprising at least two telesocpically engaging tubular parts disposed in overlapping relation to define a common area of overlap; and clamping means mounted within the innermost part of said parts for pressing said innermost part radially outwardly against the outermost part within said area of overlap, said clamping means including a triangularly shaped plate within said area of overlap and having a three-point mounting on said innermost part and means for pivoting said plate to expand the innermost part of said parts radially against the outermost part of said parts.

Claim 15

A warp beam comprising at least two telesocpically engaging tubular parts disposed in overlapping relation to define a common area of overlap; and clamping means mounted within the innermost part of said parts for pressing said innermost part radially outwardly against the outermost part within said area of overlap, said clamping means including a triangularly shaped plate within said area of overlap and having a three-point mounting on said innermost part and means for pivoting said plate to expand the innermost part of said parts radially against the outermost part of said parts.
