Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A tool for joining simultaneously a number of crosswise arranged reinforcing bars as used in concrete casting of road beds by means of pre-fabricated, partially circular shaped retaining members fastened to a reinforcing bar, said tool comprising in combination means to grip and pull said reinforcing bar and means to push against other parallel and crOsswise arranged reinforcing bars thereby forcing said parallel bars into recesses existing between said partially circular shaped retaining members and said first reinforcing bar.
Claim 2
Dependent Claim
79 words
A tool for joining simultaneously a number of crosswise arranged reinforcing bars as used in concrete casting of road beds by means of pre-fabricated, partially circular shaped retaining members fastened to a reinforcing bar, said tool comprising in combination means to grip and pull said reinforcing bar and means to push against other parallel and crOsswise arranged reinforcing bars thereby forcing said parallel bars into recesses existing between said partially circular shaped retaining members and said first reinforcing bar.
Claim 3
Dependent Claim
101 words
A tool according to claim 1 comprising a main member adapted to be laid across parallel arranged reinforcing bars and a number of prong-type members connected approximately perpendicular to said main member, said prong-type members extending thru the spaces existing between said parallel bars and adapted to push at right angles against said bars, a fork-shaped gripping tool pivotally mounted to said main member, said fork-shape adapted to straddle and lock onto a reinforcing bar extending crosswise and below said parallel bars, and the pivot action of said tool adapted to exert a relative pull on said crosswise arranged reinforcing bar.
Claim 4
Dependent Claim
64 words
A tool according to claim 2, whereby said fork-shaped and pivotally mounted gripping tool comprises two fork members with a tapered opening between same to accommodate different sizes of bars and two knife-like edges produced by sloping the two inside surfaces away from a plane centered between said fork members, said edges adapted to partially cut into said bar thereby to lock onto same.
