3 Claims. (Cl. 30-30) This invention relates to hair shapers of the type commonly used in beauty shops and salons, the hair shaper being designed to impart a desired end form to strands of womens hair.

One of the primary objects of this invention is to provide a hair shaper which includes a housing for a detachable cutting blade, a toothed guard for said blade, the guard being releasably mounted on the aforementioned housing, and attachment means for shifting the guard relative to the blade whereby the efiective life of the cutting blade is increased at least twice.

Another object of this invention is to provide on the housing means an attachment engageable, with the guard to efiect longitudinal shifting thereof relative to the cutting blade.

A further object of this invention is to provide a cutting blade mounting or housing of a type having guard teeth for the cutting edge of the blade shiftable longitudinally thereof in order to afford the cutting blade two positions of use wherein the cutting blade has exposed portions in two positions, one of which is idle when said guard is moved from a first to a second position.

This invention contemplates, as a further object thereof, the provision of an attachment for a hair shaper which is non-complex in construction and assembly, inexpensive to manufacture and maintain and durable in use.

Other and further objects and advantages of the instant invention will become more evident from a consideration of the followingspecification when read in conjunction with the annexed drawing, in which:

Figure 1 is a perspective view of a hair shaper together with an attachment constructed in accordance with the instant invention; I

Figure 2 is an enlarged longitudinally extending medial cross-sectional view of the hair shaper and attachment shown in Figure 1 and illustrating two positions of the blade guard with respect to its associated cutting blade; Figure 3 is a detail cross-sectional view of the hair shaper and attachmennFigure 3 being taken substantially on the vertical plane of line 3-3 of Figure 2, looking in the direction of the arrows; and

Figure 4 is an enlarged exploded perspective view of the attachment means employed for shifting the aforernen tioned guard relative to the cutting blade. Referring now more specifically to the drawing, reference numeral 10 designates, in general, a hair shaper constructed in accordance with the teachings of this invention and is seen to include a pair of arcuately shaped spaced handle members 12, 14 fixedly connected together at one of their respective adjacent ends by a pin 16 in conjunction with a spacer 18. On one end of a blade holder 20 is a solid end portion 22 which extends between the opposed adjacent ends of the handle members 12, 14 and is fixedly secured thereto on a pivot pin 24. The end portion 22 terminates in a tongue 26 which projects beyond the pin 24 and is provided with an arcuate finger receiving recess 28 in an edge thereof. The solid end Patented Apr. 18, 1 961 portion 22 is formed with a conventional ribbed finger engaging arcuate recess 30 in that edge of the tongue opposed to the recess 28.

The blade holder 20 is U-shaped and includes a bight portion 32 from the opposed longitudinal edges of which rise longitudinally extending inwardly converging resilient side walls 34, 36. Slidably and removably insertable through the open outer end of the holder 20 is a razor blade 38 having a longitudinally extending cutting edge 40, the other longitudinal edge of the blade 38 being engaged in a U-shaped saddle 42 having a pair of longitudinally extending blade receiving side flanges 44 (only one of which is shown see Figure 2) connected by a bight portion 46. The razor blade may be of the type manufactured by Week of Brooklyn, New York, No. 265, though other similar single edge blades may be substituted therefor.

Located in the underside of the blade holder 20 and slidably mounted for longitudinal movement on its bight portion 32 and its associated side walls 34, 36 is a conventional channel guard 48 having a plurality of longitudinally spaced guard teeth 50 projecting laterally beyond the cutting edge 40 of the blade 38 on one side thereof. The guard 48 is shiftable along the holder until the inner end thereof engages against an abutment 52 formed on and projecting downwardly from the adjacent end of the solid end portion 22.

Longitudinal movement of the guard 48 relative to the blade 38 in the direction of the arrows A (see Figure 2) is effected by a slide assembly 53 (see Figure 1) which includes as an element thereof, a bridge 54 illustrated in Figure 4. The bridge 54 has a substantially inverted U-shaped configuration and has a bight portion 56 from the longitudinally extending sides of which depend a pair of . side walls 57, 58. The bight portion 56 substantially spans the recess 30 with the side walls 57, 58 engaging against opposed sides of the solid portion 22. As is seen in Figure 3, the lower free ends 60, 62 of the side walls 57, 58 are bent around the lower edge of the solid portion 22 thereby firmly securing the bridge 54 thereto.

Superimposed on the bight portion 56 is a leaf spring 64 which includes a central portion 66 bowed upwardly away. therefrom and opposed terminal ends 68, 70 slidably engaged thereagainst. From the central portion 66 upwardly projects a normally upright pin 72 having a pair of opposed vertically extending parallel slots 74, 76. The arrangement is such that the outer edge of the terminal end 68 is disposed in confronting relation to the adjacent end of the guard 48.

Reference numeral 78 denotes an inverted substantially U-shaped saddle having a substantially flat bight portion 80 provided with a pair of longitudinally spaced holes 82, 84 which are interconnected by a slot 86. From the longitudinally extending edges of the bight portion 80 depend a pair of side walls 88, 90. The saddle 78 is engaged over the spring 64 and the bridge 54 with the upper end of the pin 72 insertedthrough either of the holes 82, 84 with the side walls 88, hearing against the outer sides ofthe bridge side walls 57, 58 to which they are fixedly secured as at 92 by conventional means. To the upper end of the pin 72 is affixed, in suitable manner, a substantially rectangular manually operated inverted V-shaped plate 94 centrally apertured at 96 to receive the pin therein.

The guard 48 in its position illustrated inFigures 1 and 2 may be shifted longitudinally from its full line position to its dotted line position through the simple expedient of depressing the plate 94 against the tension of the spring 64 until the slots 74, 76 are aligned with the slot 86. The plate 94 is then moved to cause the pin 72 to pass through the slot 86 into the hole 82 and in so moving the terminal 68 engages and exerts a force 3 r on the guard 48 causing the same to move longitudinally of the housing20.' Release of the plate 94 causes the pin 72 to move upwardly'in the hole 82 and lock the plate 94'against longitudinal displacement. 7 In its original 'full' line positionftheteeth50 overlap substantially one-half the length'of the blade 38'at longitudinally-spaced intervals The length of movement of the pin 72 from the hole 84 to the hole'82'is just sufficient to cause the guard 48 to move'longitudinally of the blade 38 to uncover the other one-half of the blade for exposure between the teeth 50 thereby increasing two-fold the elfectivelife of the blade. i i
