Safety razor

Claim 1

An improved safety razor utilizing a double-edged razor blade having opposed longitudinal outer cutting edges and for the removal of unsightly and unwanted hair from the human body, said razor having: a. a body provided with a base portion and two opposed side portions projecting from said base portions, 1. said base portion being provided with an operating slot, 2. said base portions and said side portions defining an operating cavity, and 3. each of said side portions having on its free end a resilient body mounting lip, b. a bridge member disposed adjacent said side portions and having a longitudinal portion extending longitudinally with respect to said operating cavity, a first pair of wing portions each extending transversely from one end of said longitudinal portion toward said adjacent resilient body mounting lip, and a second pair of wing portions each extending transversely from the other end of said longitudinal portion toward said adjacent body mounting lip, c. a pair of toothed members, each pivotally adjacent said longitudinal portion of said bridge member on an opposed first wing member and a second wing member and extending transversely toward an adjacent side portion of said body, 1. each of said toothed members having, a. A mounting lip engageable with an adjacent resilient body mounting lip on said side portion of said body, b. a plurality of teeth on said mounting lip and extending beyond said mounting lip for cooperation with a longitudinal cutting edge of said blade to remove said hair from said human body, c. an arm depending from said toothed member into said operating cavity, d. a first operating lug adjacent one end of said teeth, e. a pair of blade retaining members each pivotally mounted on the outer portions of an opposed first wing member and a second wing member, and having a second operating lug disposed adjacent a first operating lug of said toothed member, f. biasing means connecting said longitudinal portion of said bridge member to said base portion of said body for normally biasing said bridge member and said toothed members from a blade loading open position toward said base portion of said body and for causing said second operating lugs on said blade retaining members to move away from said first operating lugs on said blade retaining members and toward said base portion of said body to secure said blade between said toothed members and said blade retaining members in a blade operating closed position, g. a pair of crossed levers pivotal on each other inside said operating cavity and each having: 1. its inner end pivotally connected to an adjacent arm of a toothed member, and 2. its outer end extending through said operating slot in said base portion of said body; h. said outer ends of said crossed levers being movable toward each other against the action of said biasing means to move said inner ends of said crossed levers toward each other thereby causing the inner ends of said toothed members to move on said resilient body mounting lips away from said base portion of said body and said bridge member on which said inner ends of said toothed members are pivoted to move away from said base portion of said body, so that said second operating lugs on said blade retaining members move into engagement with said first operating lugs on said toothed members to cause the inner ends of such blade retaining members to move outwardly from their blade operating closed position for retaining said blade against said toothed members to their blade loading open position where said blade may be removed from said razor.
