June 3, 1952 T. DRAKE SHEATHED RAZOR BLADE HOLDER Filed July 31, 1950 M y w J INVENTOR.
HOWARD T DRAKE .4 TTORNE Y spherical projection 32 disposed on the inner surface of section 25.
In assembling slidable sections 25 and 26, section 26 is disposed at an angle to the blade I4 so that an end of rib 21 and flange 30 extends through a widened portion of slot 28. Section 26 and blade H are then moved longitudinally with respect to one another until rib 21 is disposed in slot 28 as shown in the drawing with section 26 on one side'of blade l4 and flange 30 on the other side. Section 25 is next slid longitudinally over the other side of blade l4 until the slot 29 of section 25 receives the rib 21. When sections 25 and 26 are fully aligned the projection 32 enters into the recess 3| to lock sections 25 and 26 together. Rib 21 and flange 30 are of such dimensions that flange 30 exerts a continuous pressure on section 25 tending to draw section 25 toward section 26. Sections 25 and 26 are free to move together longitudinally with respect to blade I since rib 21 slides freely in slot 28. The longitudinal movement of sections 25 and 26 with respect to the blade is limited in one direction by rib 21 which will contact the end of slot 28 and is limited in the other direction by legs [9 and 20 which contact ends 39 and 40 of sections 25 and 26 to stop further longitudinal movement of sections-25 and 26 toward legs l9 and 20.
Sections 25 and Marc provided with registering apertures 33 and 34, respectively, through which may extend a chain ring 35. Section 25 may be provided adjacent aperture 33 with a projection 36. Section 26 is provided with a recess 38 which extends to the end of section 26 and registers with projection 36 when sections 25,and 26 are in their operative positions. Recess 36 permits a finger nail to be inserted between sections .25 and 26 to engage projection 36 for moving section 25 longitudinally with respect to section 26 when it is desired to separate sections 25 and 26 to replace blade l4 or to turn blade I so that the positions of edges 23 and 24 of blade I4 are reversed. It will be apparent that the chin ring 35 must be removed before longitudinal motion of section 25 with respect to section 26 can take place.
The ends 39 and 40 of sections 25 and 26, respectively abut the sides 4| and 42 of legs l9 and 20, respectively, when movable sections 25 and 26 are in closed position,rwhile the adjoining inner edges of sections I and II abut the inner adjoining edges of sections 25 and 26, respectively, so that the outer surfaces of sections In, I I, 25 and 26 form a smooth flush surface. When in closed position, the projections 2| and 22 in ends I! and 20, respectively, engage in recesses, not shown, in the adjoining edges of sections 25 and 26, respectively, so that sections 25 and 26 tend to remain in closed position until a positive effort is made to move sections 25 and 26 longitudinally with respect to blade I4, the sections bending slightly to allow projections 2| and 22 to move out of the depressionsin sections 25 and 26.
It will be noted that sections 25 and 26 are of such width as to extend a substantial distance beyond edge 24 of blade I4. In'order'that sections 25 and 26 are provided with-narrow registering slots 43 and 44, respectively, which extend inwardly at an angle from the outer edges of sections 25 and-26 to expose a portion of edge I4 even when sections 25 and 26 are in closed position. The angularity of the registering slots 43 and M facilitates cutting of thread, gut leaders of fishing line and the like, which objects are forcibly thrust against the blade edge with a ferred embodiment of my invention it will be apparent that various changes and modifications can be made without departing from the spirit of my invention and I, therefore, aim in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of my invention.
What is claimed is:
1. In a holder for a razor blade, a blade having two cutting edges and provided with end recesses and a central longitudinal slot. a first pair of sections disposed on opposite sides of said blade, a pair of securing means connecting said first pair of sections and bein disposed on opposite ends of said blade, each of said securing meansextending through one of said end recesses to fix said blade immovably withrespect to said two sections, said two sections covering one of said two edges of said blade; a second pair of sections disposed on opposite sides of said blade; and a flanged rib formed on one of said second pair of sections and extending through said longitudinal slot, of said blade and engaging in a slot in the other of said second pair of sections and connecting said second pair of sections together, said rib being longitudinally movable in the slot of said blade, said second pair of sections'extending beyond the other of said two edges and being movable with said rib longitudinally in relation to said first pair of sections, to uncover a portion of the other of said two edges.
2. The device of claim 1 and means operatively associated with said two pairs of sections for resisting longitudinal displacement of said second pair of sections in relation to said first pair of sections when saidsecond pair of sections is in closed position.
3. In a blade holder, a blade having two cutting edges and a longitudinal slot extending therebetween, a first pair of sections disposed on opposite sides of said blade and rigidly secured to said blade, said sections covering one of said two cutting edges of said blade, each of said sections having an end extension extending toward the central longitudinal axis of said blade; 9. secand pair of sections disposed on opposite sides of said blade, a longitudinal rib on one of said second pair of sections extending through the longitudinal slot of said blade and into a slot in the other of said second pair of sections, a flange on said rib for releasably connecting said second pair of sections together, said second pair of sections being slidably movable along said blade toward and away from said extensions of said first pair of sections, said second pair 'of sections covering and extending beyond the other of said two cutting edges, said second pair of sections uncovering a portion of said other of said two cutting edges when said second pair of sections is moved longitudinally away from said extens1ons.
4. The device of claim 3, and means operatively associated with said two pairs of sections for resisting displacement of said second pair of sections from closed position.
5. In a blade holder, a blade having two cutting edges and a longitudinal slot extending therebetween, a first pair of sections disposed on opposite sides of said blade and rigidly secured to said blade, said sections covering one of said two cutting edges of said blade; a third section cooperating with one section of said first pair of sections to cover one side of said blade; a longitudinally slotted fourth section cooperating with the other of said first pair of sections to cover the other side of said blade, said third and fourth sections being correspondingly recessed at one end to receive portions of said first pair of sections; a rib rigidly formed on said third section and extending through the longitudinal slot of said blade and into the longitudinal slot of said fourth section, an outwardly extending flange on said rib to hold said third and fourth sections against lateral displacement, said third and fourth sections being movable longitudinally with respect to said blade, and means for resisting 1ongitudinal movement of said third and fourth sections.
6. In a blade holder, a blade having two cutting edges and a longitudinal slot extending therebetween, a pair of members adapted to be rigidly secured to said blade to cover one of said two cutting edges, said member having extensions parallel to the sides of said blade and extending toward the central longitudinal axis of said blade, a third member provided with a rib adapted to pass through said longitudinal slot and terminating in a flange which extends paral lel to said blade; and a fourth member having a slot in which said rib engages, said third and fourth members being adapted to be slidably disposed on opposite sides of said blade to cover the other of said two cutting edges.
