Abstract
Abstract Two horizontal parallel heddle rails connected by heddles have center portions secured to a single vertical supporting rod whose lower end is engaged by an oscillating cam follower so that the heddle rails and heddles are reciprocated with the single supporting rod. The ends of the heddle rails are preferably guided in vertical grooves of stationary vertical guide bars.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
228 words
A harness arrangement for a loom comprising a single supporting rod; at least two heddle rails extending perpendicularly to said supporting rod spaced from each other along said supporting rod, and having central portions secured to said supporting rod and outer ends; heddles extending between said heddle rails and having end portions attached to said heddle rails; a pair of elongated stationary guide means parallel with said supporting rod and slidingly engaging said outer ends of said oajsKd heddle rails for guiding said heddle rails with said supporting rod; drive means connected with said supporting rod for reciprocating said supporting rod in longitudinal direction with said two heddle rails while said outer ends thereof are guided by said stationary guide means, said drive means including a driven reciprocating member engaging a first portion of said supporting rod for moving said supporting rod in a first stroke in one longitudinal direction, and a spring means engaging a second portion of said supporting rod for moving said supporting rod in a second stroke in the opposite longitudinal direction, said first and second portions being spaced transversely to a plane passing through said supporting rod and said heddle rails so that a turning moment acts on said supporting rod and said heddle rails and heddles, reducing the friction between said outer ends of said heddle rails and said stationary guide means.
Claim 2
Dependent Claim
228 words
A harness arrangement for a loom comprising a single supporting rod; at least two heddle rails extending perpendicularly to said supporting rod spaced from each other along said supporting rod, and having central portions secured to said supporting rod and outer ends; heddles extending between said heddle rails and having end portions attached to said heddle rails; a pair of elongated stationary guide means parallel with said supporting rod and slidingly engaging said outer ends of said oajsKd heddle rails for guiding said heddle rails with said supporting rod; drive means connected with said supporting rod for reciprocating said supporting rod in longitudinal direction with said two heddle rails while said outer ends thereof are guided by said stationary guide means, said drive means including a driven reciprocating member engaging a first portion of said supporting rod for moving said supporting rod in a first stroke in one longitudinal direction, and a spring means engaging a second portion of said supporting rod for moving said supporting rod in a second stroke in the opposite longitudinal direction, said first and second portions being spaced transversely to a plane passing through said supporting rod and said heddle rails so that a turning moment acts on said supporting rod and said heddle rails and heddles, reducing the friction between said outer ends of said heddle rails and said stationary guide means.
Claim 3
Dependent Claim
30 words
Harness arrangement as claimed in claim 1 comprising two slide rods secured to said ends of said heddle rails and being guided by said elongated guide means during reciprocating movement.
Claim 4
Dependent Claim
34 words
Harness arrangement as claimed in claim 2 wherein said elongated guide means are guide bars having longitudinal grooves slidably receiving said slide rods for guiding said heddle rails and supporting rod during reciprocating movement.
Claim 5
Dependent Claim
48 words
Harness arrangement as claimed in claia 1 wherein said first and second portions of said supporting rod are first and second pins transverse to said supporting rod and parallel to said heddle rails; and wherein said drive means include a reciprocating cam follower cooperating with said first pin.
Claim 6
Dependent Claim
49 words
Harness arrangement as claimed in claim 1 wherein said end portions of said heddles are loops receiving said heddle rails; and wherein at least the loops on one of said heddle rails fits on said heddle rails so that said heddles reciprocate with said heddle rails almost without play.
Claim 7
Dependent Claim
29 words
Harness arrangement as claimed in claim 1 including at least one reinforcing rod detachably connecting said heddle rails spaced from saiD ends, and being parallel to said supporting rod.
Claim 8
Dependent Claim
24 words
Harness arrangement as claimed in claim 1 comprising attaching means for securing said center portions of said heddle rails detachably to said supporting bar.
