Abstract

Abstract A handtool for wire tying of reinforcing bars or the like is equipped with means to avoid bunching or piling of the convolutions of the tie on top of one another. Shiftable, springloaded plates on one end of the body of the tool are shifted by the ends of the wire loop during twisting such as to move the body away from the bars and leave sufficient clearance for the formation of an elongated tie with the convolutions wound spirally in side-by-side relationship, closely resembling a plier-made twist.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 95 words
In a wire-tying tool: a body; means carried by the body for feeding a wire and forming a loop about an object to be tied; means carried by the body for twisting the ends of the loop so formed, thus to attach the loop to said object; and object-engaging means on the body responsive to the operation of said twisting means for shifting the body away from the object during the twisting of said ends to cause the latter to wind spirally around each other into an elongated tie having a series of side-by-side convolutions.
Claim 2
Dependent Claim 95 words
In a wire-tying tool: a body; means carried by the body for feeding a wire and forming a loop about an object to be tied; means carried by the body for twisting the ends of the loop so formed, thus to attach the loop to said object; and object-engaging means on the body responsive to the operation of said twisting means for shifting the body away from the object during the twisting of said ends to cause the latter to wind spirally around each other into an elongated tie having a series of side-by-side convolutions.
Claim 3
Dependent Claim 34 words
In a wire-tying tool as claimed in claim 1, said object-engaging means being shiftably mounted on the body and disposed for movement away from the body by said ends during twisting of the latter.
Claim 4
Dependent Claim 24 words
In a wire-tying tool as claimed in claim 2, said object-engaging means including an element disposed for engagement by each of said ends respectively.
Claim 5
Dependent Claim 24 words
In a wire-tying tool as claimed in claim 3, said elements having cam edges slidably engaged by said ends during twisting of the latter.
Claim 6
Dependent Claim 73 words
In a wire-tying tool as claimed in claim 1, said object-engaging means including a pair of members shiftably mounted on the body and disposed for movement away from the body by said ends during twisting of the latter, each member having an element around which the loop is formed and disposed for engagement by each of said ends respectively, said elements having spaced termini for clearing said tie as the latter is formed.
Claim 7
Dependent Claim 19 words
In a wire-tying tool as claimed in claim 5; and resIlient means yieldably biasing said members toward the body.
Claim 8
Dependent Claim 29 words
In a wire-tying tool as claimed in claim 5, said elements having cam edges terminating at said termini and slidably engaged by said ends during twisting of the latter.
Claim 9
Dependent Claim 27 words
In a wire-tying tool as claimed in claim 7, said elements comprising triangular portions of said members having corners forming said termini, said edges being in alignment.
Claim 10
Dependent Claim 23 words
In a wire-tying tool as claimed in claim 8, said edges being beveled on those surfaces of said portions which face the body.
Claim 11
Dependent Claim 27 words
In a wire-tying tool as claimed in claim 9; and resilient means interposed between the members and the body for yieldably biasing the members toward the body.
