Abstract
Abstract A tool, for example, shears, having clearance adjusting means between pivotal cooperating members or blades. An adjustable ride in the means is provided to facilitate adjustments of cutting blade clearance. The ride is concentrically circumposed around the pivot stud or bolt and interposed between the members or blades. Application is made to scroll shears or snips with an offset cutting edge with relation to the flank of the shear, in order to obtain clearance to scroll slightly to the right, while retaining full maneuverability to the left.

Total Claims: 14
Claim 1
Independent Claim
218 words
A tool having two cooperating pivotal members and clearance adjusting means for said members; comprising a pivotal stud, said cooperating members being rotatably disposed on said stud, and two threaded members; said stud comprising a non-threaded intermediate portion including a ride member at one end thereof, a first threaded portion extending from said ride member and a second threaded portion extending from the other end of said intermediate portion; one of said cooperating members having a threaded bore threadedly engaging said first threaded portion of said stud, at least one of said cooperating members having a recess accommodating at least a portion of said ride member for axial adjustment therein, the other of said cooperating members having a bore accommodating said intermediate portion of said stud for rotation therein; one of said threaded members threadedly engaging said threaded portion of said stud adjacent said one of said cooperating members, the other of said threaded members threadedly engaging second threaded portion of said stud adjacent said second cooperating member, said ride member being axially adjustable to provide a desired spaced position between said cooperating members when said threaded members are loosened on said stud and the latter rotated and being fixed in said position when said threaded members are tightened on said stud with relation to said cooperating members.
Claim 2
Dependent Claim
218 words
A tool having two cooperating pivotal members and clearance adjusting means for said members; comprising a pivotal stud, said cooperating members being rotatably disposed on said stud, and two threaded members; said stud comprising a non-threaded intermediate portion including a ride member at one end thereof, a first threaded portion extending from said ride member and a second threaded portion extending from the other end of said intermediate portion; one of said cooperating members having a threaded bore threadedly engaging said first threaded portion of said stud, at least one of said cooperating members having a recess accommodating at least a portion of said ride member for axial adjustment therein, the other of said cooperating members having a bore accommodating said intermediate portion of said stud for rotation therein; one of said threaded members threadedly engaging said threaded portion of said stud adjacent said one of said cooperating members, the other of said threaded members threadedly engaging second threaded portion of said stud adjacent said second cooperating member, said ride member being axially adjustable to provide a desired spaced position between said cooperating members when said threaded members are loosened on said stud and the latter rotated and being fixed in said position when said threaded members are tightened on said stud with relation to said cooperating members.
