DETAILED DESCRIPTION OF THE INVENTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessarily to scale, some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.

FIG. 1 illustrates an exploded view of the blade cartridge 3. The figure illustrates springs 34, spring fixers 35, and plates 36 which are received on posts 61 of jacket 6 of first blade 4. The Figure further illustrates second blade 5 with holes 51 which posts 61 run through. The figure further illustrates agitator receiver 32 of second blade 5. The blade cartridge 3 is made for a movable stacked arrangement. The second blade 5 is designed to be placed on top of the first blade 4. The holes 51 on the second blade 5 are designed to be received by the posts 61 of first blade 4. The holes 51 have a length that is greater than the diameter of the posts 61, this allows the second blade 5 to reciprocate to create a cutting action. The second blade 5 is secured in position adjacent the first blade 4 by blade fixers 35 that use springs 34 and plates 36 to create the optimal tension between the blades for the most effective cutting action. The agitator receiver 32 receives the agitator 14 to create the actual motion for the cutting action.

FIG. 2 illustrates the hair trimming apparatus having a blade cartridge 3 attached to the first end (handle) 12. The figure further depicts the blade cartridge 3, showing the first blade 4 with a rear surface 41 having an etching (or etched surface) 42 and the jacket 6. The figure further illustrates the housing 1 having an exterior surface 11 and a light 8. The light 8 provides illumination for the area that the hair trimming apparatus is being used. The etching 42 on the rear surface 41 provides for smooth movement over a user's skin.

FIG. 3 illustrates the hair trimming apparatus with housing 1 without a head or blade cartridge 3 attached. The figure shows the agitator 14, light 8, and exterior surface 11 of the housing at the first end 12. The housing 1 has a mostly hollow internal cavity (not shown). The internal cavity of the housing contains a power source (not shown) that is connected to a motor (not shown) and a transmission (not shown) that is connected to and drives the agitator 14. The motor is also connected to circuitry and wire that link it to the button 7, the button 7 allows a user to turn the device on and off. The internal housing further contains a power source (not shown) that can be a disposable or rechargeable battery. The power source provides the energy to operate the motor, the motor and power source are connected to one another.

FIG. 4 illustrates the hair trimming apparatus with housing 1 without a head attached. The figure shows a button 7 that is at the first end (handle) 12 of the housing 1. The button 7 is linked to internal circuitry and wire that allow the user to power the hair trimming apparatus on and off.

Numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the attendant claims attached hereto, this invention may be practiced otherwise than as specifically disclosed herein.
