i TOOL FOR GRIPJPING AND CUTTING WIRE.
Application filed June 20, 1925. Serial No. 38,450.
This invention relates to wire working tools and more particularly to a combined gripping and cutting tool particularly adapted for use in removing the wire fastenings from cement bags and the like.
The object'of the present invention is to provide an improved tool of the character indicated capable of cutting the loop of such a wire fastening while at the same time and with the same movement gripping the twisted parts of the fastening for pulling the same way from the bag. A further ob ject of this invention is to provide a tool of this character so constructed that it is practically impossible to injure the bag in the opening operation.
The invention consists in the novel construction, arrangement and combinations of" parts as hereinafter more particularly described and claimed.
One sheet of drawings accompanies this specification as part thereof, in which like reference characters indicate like parts throughout.
Fig. 1 is a perspective view of the improved tool applied to a sack fastening preliminary to cutting the same.
Fig. 2 is a fragmentary perspective view of the tool applied to a wire fastening loop the sack being indicated in dotted lines.
- Fig. 3 is a fragmentary front view of the improved tool.
Fig. 4 is a fragmentary back view of the tool.
In accordance with the present invention two lever members 1 are secured in pivoted crossed relation as by bolt 2. Handles 3 are provided at the ends of the longer arms of the members 1. a a
The short arm 4: of one of the members 1 is provided with a laterally directed curved flange 5 adapted to receive the short arm 6 of the other member 1. The lower edge of the short arm 4; beneath the flange 5 is pro vided with an arcuate notch 7 which is beveled outwardly as indicated by 8 to pro-' vide a shearing edge on the inner face of the arm 4.
together and secured by a loop of wire 9 the ends of which are twisted together as at 11. To remove this loop with my improved tool the twisted part 11 of the fastening is en tered between the short arm 6 and the flange 5 and the tool forced against the neck of the sack 10 until the loop part 9 of the fast a it will be noted that by reasonof the arcuate notch 7. the loop 9 is drawn by the initial movements of the operation away from the sack thus further insuring the sack from in jury. If the twisted part of the loop happens to be bent in or if the bag happens to present itself to the workman with another portion of the loop toward him, it is not necessary, with this tool to seek the twisted part of the loop as it will operate efficiently on any part thereof. Where the loop proper is grasped betweenthe nippers a portion thereof is forced into the grooved flange transversely thereof and firmly gripped while at the same time the loop is severed to one side of the gripped part as will be apparent from the structure of the tool.
Having. thus fully described my invention, I claim 1. A wire gripping and cutting tool comprising blunt ended pivoted members, one of said members having a laterally directed curved flange adapted to receive the other member and further provided with an arcuate notch opposite said flange said notch having a shearing edge adapted to engage with the upper edge of the second member.
2. A wire gripping and cutting tool comprising pivoted members having blunt ends in substantially a common plane, one of said members having a laterally directed curved flange adapted to receive the second member and further provided with an arcuate notch extending from its blunt end rearwardly and on the face opposite the flange said notch having a shearing edge adapted to cooperate with the upper edge of the second member.
