Abstract
Abstract In a machine for mounting metal wire handles on pots, pails and similar containers, in which the handle ends are bent twice in such a way that by the second bending operation the bent-over ends provided by the first bending operation are inserted into handle fittings on the container, only a single set of bending tools are used for performing both bending operations. Preferably the two bending operations are performed by a single bending slide performing two successive bending movements in the same direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
118 words
In a machine for mounting wire handles on containers provided with handle fittings, said machine having means for positioning a container and orienting its fittings in a predetermined direction and means for forming a wire handle to generally U-shape and positioning the ends thereof to extend downwardly adjacent said fittings, the improvement comprising: bending tools including reciprocable members movable in one direction to bend the ends of a wire handle inwardly toward said fittings to define first bends; said machine including further means for causing said members to engage said handles at positions spaced from said first bends and form second inward bends whereby said first bends are bent inwardly and upwardly into handle-mounting engagement with said fittings.
Claim 2
Dependent Claim
118 words
In a machine for mounting wire handles on containers provided with handle fittings, said machine having means for positioning a container and orienting its fittings in a predetermined direction and means for forming a wire handle to generally U-shape and positioning the ends thereof to extend downwardly adjacent said fittings, the improvement comprising: bending tools including reciprocable members movable in one direction to bend the ends of a wire handle inwardly toward said fittings to define first bends; said machine including further means for causing said members to engage said handles at positions spaced from said first bends and form second inward bends whereby said first bends are bent inwardly and upwardly into handle-mounting engagement with said fittings.
Claim 3
Dependent Claim
31 words
A machine as defined in claim 1 including means for retracting said members after forming said first bends and moving the same inwardly a second time to form said second bends.
Claim 4
Dependent Claim
68 words
A machine as defined in claim 3 wherein said bending tools include stationary anvils adjacent said handle and about which said first bends are formed, means for removing said anvils while said members are retracted, and said members having a first portion for engaging said handles to form said first bends and a second portion engageable with said handles to form said second bends upon a second reciprocation.
Claim 5
Dependent Claim
19 words
A machine as defined in claim 2 including means for moving said handle downwardly while said members are retracted.
Claim 6
Dependent Claim
21 words
A machine as defined in claim 4 wherein said last-named means compresses said means for forming said handle to generally U-shape.
