Abstract
Abstract A pedestal for supporting an electric scissors having a housing and a ledger blade mounted at the front of the housing. The pedestal comprises a plastic plate having formed therein a longitudinal slot extending from the upper surface to the lower surface thereof. An integral bridging member longitudinally spans the slot at the upper surface of the plate. A blade-receiving slot is formed in the bridging member for detachably connecting the ledger blade to the pedestal. The blade receiving slot includes an abutment surface against which the ledger blade coacts to prevent the blade from inadvertently withdrawing from the slot. A longitudinal recess may extend along the lower surface of the plate from the termination of the slot to control the amount of springyness of the pedestal. The pedestal is such that it not only supports the scissors on a cutting surface but dampens the vibrations and thus the noise level transmitted from the scissors to the cutting surface.

A pedestal for supporting an electric scissors having a lower ledger blade, said pedestal comprising a plate of resilient material having a substantially flat bottom face and an upper exposed face, means defining a longitudinal slot in said plate extending from the upper face to the lower face thereof, a resilient bridging member integral with said plate longitudinally spanning said slot on the upper face of said plate, and means on said bridging member for detachably connecting the ledger blade to the bridging member.
Claim 2
Dependent Claim
84 words
A pedestal for supporting an electric scissors having a lower ledger blade, said pedestal comprising a plate of resilient material having a substantially flat bottom face and an upper exposed face, means defining a longitudinal slot in said plate extending from the upper face to the lower face thereof, a resilient bridging member integral with said plate longitudinally spanning said slot on the upper face of said plate, and means on said bridging member for detachably connecting the ledger blade to the bridging member.
Claim 3
Dependent Claim
21 words
A pedestal as defined in claim 1 wherein the lower surface of the plate abutting the slot includes a longitudinal recess.
Claim 4
Dependent Claim
67 words
A pedestal as defined in claim 1 wherein said bridging member extends above the upper face of said plate, said means for detachably connecting the ledger blade to the bridging member includes a vertical slot formed in the bridging member for receiving said ledger blade, said slot being downwardly tapered at its leading edge to form an abutment against which the leading edge of the blade coacts.
