Y q Y (oise- 245) l Y claims.
This invention relates to shears or soissorsfand particularly to a new andvuseful method for actuating the cutting members thereof.
The object of this invention is to provide a novel means whereby the power to operate such shears may be supplied by the palm and fingers of the hand instead of the usual ngers and thumb method of operating the cutting members.
Another object of this invention is to provide a simple palm and lingers controlled shears that may be readily used upon a plane surface lsuch as a table, and in which shears, a single blade is actuated to perform the cutting operation.
Another object of this invention is to provide a shears having the articulated blade operating member lever and palm member positioned at a,V
convenient angle with respect to the cutting blade, to facilitate control of the shears and` prevent undue muscular fatigue commonly experienced in using the conventional type of shears.
Another object of this invention is to provide serrated edge blade members having non-radially generated teeth adapted to self lapping contact with each other to provide complementary cut-'f ting edges. i Y- Fig. 3 is a fragmentary sectional view taken on line a/-a in Fig. 2.
Reference numerals indicate the same parts in the several drawings.
In the vpractice of the invention as herein exemplied, it will be noted from the disclosure,
that the natural position of the hand in gripping an object may be easily extended to the operation of the present invention with a minimum of fatigue. That extended use will not produce the usual occupational muscular cramp often experienced by those lcompelled to use the conventional tools provided for shearing. The principle of palm and fingers gripping 4of ashearing means may be applied without departure from the present invention to ordinary shears, scissors and metal snips, by substitution of suitableblades,
and the operative leverages proportioned toineet specic requirements.
VReferring to Fig. 2, the articulated blade supportingmember I, which has a suitable blade 5 mounted thereon, *is rigidly secured to a pivot member 21by means of a set screw 3. '-,The pvot member!y is mounted in a blade supporting base member 4 which has a blademember 6 mounted thereon. These blade members may be attached to their respective supporting members by screws' or other suitable means, the type shown inthe drawing being known as pinking shear blades.
' The baseA member 4 has an upright palm grip member 5 integral therewith and preferably disposed at approximately an angle of thirty degrees topermit easy natural position of the hand when operating the device upon a horizontal plane such as a table. f
Thearticulated or movable blade member I extends a predetermined distance tothe rear-of the pivot member 2, said extensionl being determinedV as to length by the leverage required to efficiently loperate 'the cutting blades Ii. The extended portion I is provided with a suitable congurated opening 1a adapted to operatively receive Aa complementary extension on the nger lever 9, saidA lever 9 being "pivotallyfmounted'in the base Vmember 4 and' rigidlyse'cured to the pivot member I0 by suitable means. The structure shown is a modication of a sector gear and for the purpose of simplicity is shown as a single tooth. Y
A suitable spring or resilient member II, se-
cured to the `rear face of the nger lever 9, its outward free end I2 resting againstthe inner face of the palm grip member 5 provides means for retracting the nger lever 9 and the articulated bladesupporting member I to operative or open position.
While the resilient means for retracting the respective parts has been shown interposed between the finger grip lever 9 and the palm grip- Y ping means 5, an open coil spring may be placed in a suitable opening in the under face of the lever extension 8 to exert its force against the base member 4 to effect the return of the respective parts to operative position.
The pivotal axis of the articulated blade supporting member I is disposed in the longitudinal center of the blade members 6 which obviates the necessity-for radially cutting the teeth members and permits easy lappingV of the blades to provide complementary cutting edges. Further sharpening of the blade members may be accomplished by grinding or stoning in substantially The lateral shearing alignment or frictional contact between the blade members 6 is effected by means of a set screw i4 disposed in the base member .4 adjacent to and to the rear of the longitudinal center of the pivot member 2. The
blade member l is held immovable relation tothe screw I4 by a compression spring I5 mounted on the pivot 2 and retained in the counterbored recess I6. recessedl male threaded bearing member l' screwed into the base member 4 provides supporting means for the outer endof the, pivot 2 and compresses the'spring i5 to maintainY operative'alignment between the blade mem-V bers E.
The disposition of theset screw lit tothe rearl Vof the pivot 2 increases theI tendency' toward tending the liand returns the articulated. blade.
