Abstract:
The pivotable blade hair clipper and suction collection system cuts hair from the head or any body surface, plus safely and immediately suctions away clipped hair debris. The system provides a vacuum canister, suction hose, suctionable clipper handle, pivoting blades, back-reach attachment, rolling and combing guard/gauges built-in mirror, and safety features. The vacuum switch powers the clipper motor utilizing wiring housed within the suction hose. A finger-pivoted blade assembly provides ergonomic angles for cutting the hair. Hair debris is suctioned through the clipper handle and collected in a personally sized vacuum canister. A back-reach attachment extends the clipper to hard-to-reach body surfaces. A built-in mirror encourages safely positioning the canister and hose. Safety venting nullifies nicks. Minimal external cording prevents tangled cords. Three types of guard/gauge provide conventional hair trimming, combing motion for flat surfaces, or rolling motion for comfort at the underarm and bikini.

This application claims the benefit of Provisional Application No: 60/360,769, filed Mar. 1, 2002. 
    
    
     BACKGROUND OF THE INVENTION: 
     The present invention relates to electric hair clippers, trimmers and shavers, and specifically to such devices having blade assemblies that are pivotable and in some cases detachable relative to the handle portion. 
     Presently there are three methods used to cut human head hair or body hair: the manual razor, the electric clipper, and the electric clipper combined with additional attachments such as a household vacuum. 
     A major advantage of the manual razor is that it provides a simple, skin close hair cut. Inherent in its simplicity, however, are the disadvantages or being unable to accurately and consistently gauge hair cutting lengths other than skin-close, of the opportunity to nick one&#39;s skin with such a razor, and that any such hair trimming is achieved with no opportunity to perform the task neatly and without the need for clean up afterward. 
     Conventional electric hair clipper systems include two main components: a combined handle and drive system, and a removable or adjustable hair length gauge that functions to comb the hair toward a set of reciprocating blades. The blade assembly typically includes a fixed blade and a moving blade coaxially reciprocating relative to the fixed blade. In addition to removing hair on the human head, conventional electric hair clippers are often used to remove unwanted or unhygienic body hair. A major disadvantage of conventional hair trimming methods, especially concerning the removal of body hair, is that electric clippers are not designed to accommodate the users anatomy beyond certain parts of the head such as scalp, beard and neck. Without skin protection, such as a safety guard, and without a design that allows a user to access certain hard-to-reach or sensitive body surfaces such as the back, conventional hair clippers can be awkward and inaccurate, even injurious during any such body hair application. 
     Electric hair clippers are occasionally used with vacuum attachment means to evacuate clipped hair debris. While the obvious advantage of neatness is addressed using this clipper method there remain some equally obvious disadvantages. More specifically, no matter whether the operator intends to use such a clipper system to cut head hair or to cut body hair the shape of the hair clipper with its attachments is unwieldy and does not accommodate certain hard-to-reach or sensitive body surfaces for hygienic clipping. Also the hair clipper attachments are typically intended for use with a household vacuum producing a very definite and very loud noise in the work area while in operation, and not every household that could benefit from a home hair clipper set possesses a type of vacuum appropriate for this clipper method. 
     One disadvantage of these conventional hair clipper units having attachments that serve as a comb, or guide, or length gauge is the difficulty in efficiently placing or aligning the typically large, attachments on the skin surface of certain body areas for cutting or trimming of the hair there at predictable and consistent lengths. When utilizing conventional electric hair clippers, the operator accomplishes the hair cutting by employing a “combing” motion typically requiring a lengthy comb attachment that painfully scrapes or scratches sensitive body areas and also prevents the clipper from performing the actual hair cutting when such a method is applied in tight or close body areas such as the groin or underarm, or in other words, where there is not sufficient work area to accomplish the combing motion. The combs are typically shaped of angular plastic that catches the skin and causes scratching or scraping of the skin as well as uneven cutting of the hair and can impede the user&#39;s ability to positively control the blade position or cutting angle as the clipper is passed over the skin surface. 
     Another disadvantage of both manual razors and conventional hair clipper systems is that cut or clipped hair debris is allowed to fall back onto the skin surface or to fall into the work area requiring some type of additional work for hygienic removal of said hair debris. Furthermore, conventional hair trimming methods typically necessitate that the user acquire and organize multiple tools or tedious cleansing methods to accomplish the work from start to finish. For example, the need for vacuum attachments, a vacuum or broom, mirror aids, protective clothing such as towels or capes, and/or an array of hair debris collection or removal techniques including vacuuming, sweeping or bathing can produce a hair cutting or hair trimming experience that is frustrating, time consuming, cumbersome, or even injurious if one&#39;s skin is scratched, scraped or nicked by an attachment or by an unprotected blade. 
     Thus, an object of the present invention is to provide an improved hair clipper wherein hair clippings are immediately suctioned away through the clipper handle portion and this action requires no special parts or unwieldy attachments other than the personal size vacuum hair collection canister and suction hose distributed with and connected to the clipper unit. 
     Another object of the present invention is to provide an improved hair clipper wherein the blade assembly is easily pivotable into at least two cutting angles and provides the user with a multi use tool that either can be angled at approximately 45 degrees from perpendicular for ideally cutting hair from the head or can be angled at approximately 90 degrees from perpendicular for the ideal hygienic clipping of certain hard-to-reach or sensitive body surfaces. 
     Another object of the present invention is to provide an improved hair clipper wherein the difficult-to-reach area of the back is addressed such that the clipper is integrally designed to receive an extending attachment allowing the user to easily pass the clipper blades over the surface of the back to remove unwanted or unhygienic back hair. 
     Another object of the present invention is to provide an improved hair clipper wherein the attachments conventionally known as combs, guides or length gauges (“guard/gauges”) are designed to address the at least dual function of the improved hair clipper such that guard/gauges intended for the cutting of head hair are similar, if only in that comb portion, to those of convention with respect to shape and function of the comb portion and allow the user to accurately comb hair into the path of suctioned airflow and into the cutting blades while set at their 45 degree angle within the handle portion of the clipper and thus achieve an anticipated cut hair length; and guard/gauges intended for the cutting of body hair are specially designed to fit within the approximate 1.5 inch depth of the clipper unit, and in certain cases are specially designed for use in a “rolling” motion as well as a combing motion such that when hair on a sensitive or angled portion of the body is to be trimmed, as would be the case in the bikini area, the user can gently “roll” the body hair into the stream of air being suctioned through the handle portion of the clipper unit and into the path of the cutting blades for accurate cut length and immediate, safe, comfortable and hygienic evacuation of hair debris from the skin surface and from the work area. 
     SUMMARY OF THE INVENTION 
     Accordingly, the above-listed objects are met or exceeded by the present invention pivotable blade hair clipper and suction collection system which has a clipper handle with an integrally formed vacuum suction channel for the hygienic evacuation of hair clippings into a personal size vacuum hair collection canister by way of a suction hose, and has a pivotable blade assembly that is detachable, and has as well a back-reach attachment for extending the clipper to cut hair on the back plus guard/gauges specially contoured for cutting or trimming hair on sensitive and difficult-to-reach body surfaces, as well as guard/gauges specially contoured for cutting or trimming hair on the head and neck. 
     More specifically, the present invention includes a clipper handle having a drive end and internal suction formations, plus a blade assembly that is pivotable relative to the handle portion of the clipper to achieve comfortable head hair cutting and trimming and comfortable body hair cutting and trimming and is detachable. Additionally, three types of guard/gauge are designed for use with the present invention: one type of guard/gauge utilizes a 45-degree angle of the pivotable blade assembly and is suitable for cutting or trimming head hair and subsequently suctioning away clipped hair debris by employing a conventional combing motion; another type of guard/gauge utilizes an 80-degree angle of the pivotable bade assembly and is suitable for cutting or trimming hair on body surfaces that are relatively flat such as the back or chest and subsequently suctioning away clipped hair debris by employing a conventional combing motion, and in the case of the back by also attaching the back-reach attachment; and another type of guard/gauge utilizes an 80-degree angle of the pivotable blade assembly and is suitable for cutting or trimming hair on body surfaces that are sensitive and/or difficult-to-reach such as the bikini area by employing an unconventional “rolling” motion, which rolling motion protects sensitive skin surfaces from scratching or scraping, and which rolling motion can be achieved in close body areas such as the groin or underarm. 
     In the present invention, the pivoting feature of the at least dual position blade assembly enhances an ergonomic clipper design and enables the operator to hold the clipper in a natural manner at all times whether cutting hair on the head and neck, or cutting hair on the chest or other body surface, or using the back-reach attachment to trim hair on the surface of the back, pivoting the blade assembly as previously described changes the position of the blade assembly&#39;s cutting edges relative to the clipper handle portion to either of 45 degrees for head hair cutting or 80 degrees for body hair cutting. The pivotable design of the blade assembly ensures that an ideal cutting angle with respect to ergonomics in the users hand is achieved for all cutting techniques. Thus, the present invention hair clipper is readily altered from a head hair trimming tool, to a body hair trimming tool, to a back hair trimming tool providing a comfortable, accurate, safe and clean hair trimming experience that applies to any surface of the body. 
     The present invention air suction channel ensures that clipped hair debris is immediately suctioned free of the skin surface and the work area and deposited cleanly into the vacuum hair collection canister. The newly shaped guard/gauges ensure that a comfortable and accurate cut can be achieved by employing a “rolling” motion of the clipper unit in a space the approximate width of the clipper unit itself rather than utilizing a longer combing motion as is the convention, yet more conventionally shaped guard/gauges can also be used to “comb” the hair into the blades when cutting or trimming hair on the head or hair on a relatively flat surface of the body such as the chest. 
     In the present invention, the “rolling” action of the guard/gauges, the design and shape of the dusting blades, the pivotable blade assembly and its centralized placement in the drive end of the clipper handle, the air suction channel integrally designed into the handle portion of the clipper unit and designed integrally with the blade assembly to aerodynamically evacuate clipped hair debris, and the suction hose and vacuum hair collection canister constitute improvements to existing art and/or unique combinations of known art that will enable the user to comfortably and cleanly achieve a desired hair cut length on both the head and the body. 
     In another embodiment, the present invention provides a hair clipper including a handle portion having a drive actuator member extending from the drive end to accommodate a blade assembly reciprocative about the drive end of the handle portion, plus an air suction channel integrally formed in the handle portion to aid in the evacuation of clipped hair debris toward a means of debris collection. 
     In a further embodiment, the present invention provides a hair clipper including a handle portion having a drive actuator member extending from the drive end, plus a blade assembly that is reciprocative about the drive end of the handle portion of the clipper and that is pivotable to at least two distinct cutting angels relative to the handle portion of the clipper, plus an air suction channel integrally formed in the handle portion of the clipper to aid in the evacuation of clipped hair debris. 
     In an alternative embodiment, the present invention provides a pair clipper including a handle portion having a drive actuator member extending from the drive end, plus a blade assembly reciprocative about the drive end of the handle portion of the clipper, plus an air suction channel integrally formed in the handle portion of the clipper to aid in the evacuation of clipped hair debris. Also included in the blade assembly is a cam follower integrally shaped to maintain contact with the drive actuator member at all times during operation and means by which the blade system can be pivoted to achieve at least two distinct cutting angles relative to the handle portion of the clipper. 
     In still another embodiment, the present invention provides a vacuum hair collection canister for use with a hair clipper, the clipper including a butt portion suitable for attachment by way of a suction hose to the vacuum hair collection canister and the vacuum hair collection canister including storage space for a suction hose, clipper unit, built-in mirror, and further attachments such as combs or guards or gauges or guard/gauges and a back-reach attachment. In this embodiment, the vacuum hair collection canister shall have filtration means suitable for collecting clipped hair debris, and the clipper shall have a handle portion having a drive actuator member extending from the drive end, plus an air suction channel, integrally formed in the handle portion to aid in the evacuation of clipped hair debris toward the hair collection canister, plus a blade assembly reciprocative about the drive end. Also included in the blade assembly is a cam follower integrally shaped to maintain contact with the drive actuator member at all times during operation and means by which the blade assembly can be pivoted to achieve at least two distinct cutting angles relative to the handle portion of the clipper for achieving maximum ergonomic user comfort during all types of operation.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     GENERAL 
     Referring now to  FIG. 28 , the present invention is a pivotable blade hair clipper and suction collection system. In its preferred embodiment the present invention comprises substantive parts combined to achieve safe and comfortable clipping of head hair and body hair and the evacuation of subsequent clipped hair debris through its clipper handle, then through its suction hose, and into its vacuum hair collection canister. More specifically, a pivotable blade hair clipper and suction collection system of the type suitable for use in the present invention is generally designated  11  and comprises: a pivotable blade assembly generally designated  40 ; a clipper handle portion generally designated  70  having a clipper motor  80  with blade driving means  89 ; four distinct suction formations  61 A,  61 B,  61 C,  61 D; a flexible suction hose  66 ; a vacuum hair collection means generally designated  90 ; and accessories specific to the anticipated functionality of the present invention that include combs, blade guards, or hair length gauges (“guard/gauges”)  113 ,  114 ,  115  and a skin guard SG 1 , plus a back-reach attachment  112  and built-in mirror  98 . 
     Referring now to  FIGS. 3 and 28 , in the present invention the clipper handle  70  having a clipper motor  80  drives a pivotable blade assembly  40  that is designed to channel suctioned air  60  across its cutting portion and into the suction formations  61 A,  61 B,  61 C preferably integrally molded in the clipper handle portion  70  whether the pivotable blade assembly  40  is parked in its first position  1  or parked in its second position  2  (best seen in FIG.  3 ). The clipper unit  70  comprises a handle drive end portion  71 , a handle motor house portion  72 , a handle butt portion  73 , a motor  80  and switch  83 , plus four district suction formations  61 A,  61 B,  61 C,  61 D that are integrally designed for safely passing suctioned air  60  and clipped hair debris through the clipper unit  70  and into the suction hose  66  for evacuation into the vacuum hair collection canister  90 . 
     TERMS AND ORIENTATIONS 
     Referring now to  FIGS. 1 ,  2  and  3 , in the present invention pivotable blade hair clipper and suction collection system the handle drive end portion  71  is formed preferably of durable, impact-resistant molded polymeric or plastic material as is known in the art creating a cavity (“drive end cavity”) into which the pivotable blade assembly  40  is secured by means described in the section designated “Pivotable Blade Assembly.” It is known, therefore, that subsequent use of the term “drive end cavity” references the preferably integrally molded cavity that exists in the preferred design of the handle drive end portion  71  and into which the pivotable blade assembly  40  is secured. 
     Referring now to  FIGS. 1 and 4  concerning the terms “anterior,” “posterior,” “left lateral,” and “right lateral,” it is known that relationally the anterior of the clipper  70  corresponds to the anterior of the drive end portion  71 , which corresponds to the anterior wall of the drive end cavity, which corresponds to the anterior of the blade assembly  40 , etc. Therefore, it is known that the terms “posterior,” “left lateral,” and “right lateral” also have patterns of relative correspondence as in the pattern described for the term “anterior” above. Furthermore, in the present invention, it is known that the term “face” describes the most exterior surface of the part referenced. Therefore, in the present invention it is known that the exterior of the clipper  70 , including the handle drive end portion  71 , comprises four faces: the anterior face, the posterior face, the left lateral face, and the right lateral face, and it is known that subsequent use of each of these terms assumes a frontal orientation of the clipper handle  70 . 
     Referring now to  FIGS. 1 and 3  in the present invention it is also known that the terms “apex” and “base” relate to or orientation of the clipper  70  and its associated components that is vertical as demonstrated in FIG.  1 . It is also known that a view of the “interior” of the drive end cavity assumes a frontal orientation of the clipper handle  70 , and that subsequent description of the pivotable blade assembly  40  when described in relationship with the drive end cavity assumes a frontal orientation of the pivotable blade assembly  40  and a correspondingly frontal orientation of the clipper handle  70 , or of the handle drive end portion  71 . 
     MAIN SUCTION FORMATION 
     Referring now to  FIGS. 1 ,  2 ,  3 , and  20  in the present invention pivotable blade hair clipper and suction collection system, preferably molded integrally throughout the clipper handle  70  is a system of hollow channel for immediately suctioning away hair clippings from the cutting portion of the blade assembly  40  and fluidly through the clipper handle  70 . Designated the “main suction formation,” this hollow channel is comprised of four integral suction formations  61 A,  61 B,  61 C,  61 D. Concerning the volume of suctioned air  80 , it shall be understood by those skilled in the art that a vacuum collection means of the type suitable for the present invention will have a specific air intake volume (“optimum intake”) when operating under optimum power conditions, said optimum intake being dependent on the size of the vacuum motor  100  and other variables including the fan blade driven by said motor, as well as the inner diameter of the suction hose  66  and the intake capacity of the main suction formation  61 A,  61 B,  61 C,  61 D formed in the clipper handle  70 . 
     Referring now to FIGS,  2 ,  3  and  28 , the function of the main suction formation  61 A,  61 B,  61 C,  61 D is threefold in that firstly, it takes into the clipper handle  70  and passes around the motor house  81  a volume of suctioned air  60  having in it clipped hair debris, and secondly the preferred embodiment having a formation suitable for suction hose connection at the handle butt portion  73  passes said air and said hair debris into the suction hose  66  connected to the vacuum hair collection canister  90 , and thirdly a user safety precaution preferably is molded integrally into the clipper handle drive end  71  in the form of bilateral safety venting  61 D. Each component of the main suction formation  61 A,  61 B,  61 C,  61 D substantially contributes to provide suctioned airflow  60 , and each component, especially the bilateral safety venting  61 D and the second suction formation  61 B, also factors in providing a safety precaution  61 D sufficient in design to prevent unwanted suctioning of the skin into the cutting portion of the blades while said blades possibly are in operation without the guard/gauge attachment  113 ,  114 ,  115  or skin guard SG 1  (FIG.  2 B). 
     Referring still to  FIGS. 2 ,  3  and  28  concerning the mechanics of the suction formations in the preferred embodiment of the present invention, the first suction formation  61 A begins and is divided within the handle drive end  71  just beneath the bottom blade of the pivotable blade assembly  40  when parked in its second position  2  (beat seen in FIG.  3 ). Said formation defers at the clipper handle motor house portion  72  into bilateral conduits designated the second suction formation  61 B and which serve to pass the volume of suctioned air  60  around the motor housing, preferably dividing said volume equally and preferably not being formed at any place to constrict said volume. Said second formation defers to a formation suitable for suction hose connection  61 C in the area of the handle butt portion, which portion has attached to it a suction hose  66  for evacuation of clipped hair debris into a vacuum hair collection canister  90 . 
     Referring now to  FIGS. 2 and 28  more specifically, the suction hose  66  is preferably highly flexible having an inner volume sufficiently large and sufficiently formed to accommodate at least optimum intake. In the preferred embodiment the formation suitable for suction hose connection  61 C has sufficiently large inner volume and is sufficiently formed to accommodate at least optimum intake. Also preferable is that the second suction formation  61 B has sufficiently large inner volume at each of and is sufficiently formed at each of its bilateral components to accommodate at least half the optimum intake. Additionally, the first suction formation  61 A preferably has sufficiently large inner volume and is sufficiently formed at each of its laterally deferred edges to accommodate at least half the optimum intake. Furthermore, the bilateral safety venting  61 D preferably is sufficiently large and formed at its bilateral components to draw through each of them at least half the optimum intake. Finally, the main suction formation  61 A,  61 B,  61 C,  61 D as a whole preferably has sufficiently large inner volume and is sufficiently formed to accommodate optimum intake. 
     Referring now to  FIGS. 1 ,  2 ,  3  and  28  with respect to appearance and location of suction formations described above, at the handle drive end  71  are the bilateral safety venting  61 D and the first suction formation  61 A. In the handle motor house portion  74  is the bilaterally situated second suction formation  61 B, and in the handle butt portion  73  is the formation suitable to suction hose connection  61 C. More specifically, each of said formations is unique in its appearance and in its function, and each comprises and is integral to the overall function of the main suction formation discussed above, yet each is considered separately within the clipper handle  70  only for purposes of detailed description. 
     Referring still to  FIGS. 1 ,  2 ,  3  and  28  and concerning the bilateral safety venting  61 D sad the first suction formation  61 A, said safety venting preferably is comprised of bilaterally situated polygon shaped holes formed integrally in the lateral walls of the handle drive end portion  71  of the clipper  70 . Their shape, positioning and function are described in detail in the section designated “Handle Drive End Safety Venting.” As for this first suction formation  61 A, its shape, positioning and function are described in detail in the section designated “Handle Drive End Anterior Wall.” Concerning the second suction formation  61 B its shape, positioning and function are described in detail in the section designated “Handle Motor House Portion.” As for the formation suitable for suction hose connection  61 C its shape, positioning and function are described in detail in the section designated “Handle Butt Portion.” 
     PIVOTABLE BLADE ASSEMBLY 
     GENERAL 
     Referring now to  FIGS. 2 ,  3  and  4  in the preferred embodiment of the present invention pivotable blade hair clipper and suction collection system, the pivotable blade assembly  40  is stationed in the handle drive end  71  of the clipper  70  and preferably is secured there by means of a pivot axle male portion  42  and a pivot axle female portion  41  comprising an axle around which the blade assembly is pivotable. More specifically, the pivot axle preferably is an elongate screw  42  and a threaded elongate barrel  41  each inserted into a lateral face of the handle drive end  71  by way of the pivot axle hole  51  preferably formed integrally thereon, thus semi-permanently securing the blade assembly  40  into the clipper handle  70 . Also, in the preferred embodiment of the present invention, pivot axle componentry is configured to a one-eighth inch diameter axle. 
     PIVOTABLE MOTION 
     Referring still to  FIGS. 2 ,  3  and  4 , the blade assembly  40  has a pivotable motion about the pivot axle  41 ,  42  and preferably has dimensions tightly accommodated by the drive end cavity into which it is secured. More specifically, it is known that the preferred 35-degree pivotable motion of said blade assembly about its pivot axle  41 ,  42  has as a paramount component precise placement of the pivot axle hole  51 , which in its entirely is comprised of two holes located bilaterally in the handle drive end  71  and two holes located bilaterally in the housing  50  of the blade assembly  40  for a total of preferably four corresponding and precisely positioned holes. Furthermore, the blade assembly  40  is secured by similar means into each of its two pivot positions  1 ,  2 , said means being both the pivot axle hole  51  and safety formations  53  all preferably formed integrally in the handle drive end portion  71 , and the corresponding pivot axle hole  51  and dual position formations  52  all preferably formed integrally in the blade housing  50 , and the pivot axle  41 ,  42 . In an alternative embodiment, the pivot axle  41 ,  42  is contemplated as molded plastic integrally a part of the housing  50  of the blade assembly  40 . 
     Referring now b  FIGS. 3 ,  4  and  28 , the present invention hair clipper  70  component is readily altered from a head hair trimming tool, to a body hair trimming tool, to a back hair trimming tool by pressing inward both pivot tabs  55  of the blade assembly  40  then applying pressure upward or downward, thus disengaging said blade assembly out of one position into the newly chosen position, and then releasing said pivot tabs. The dual position formation  52  formed integrally in the housing  50  of the blade assembly  40  reseals itself onto a corresponding safety formation  53  formed integrally in the handle drive end  71  of the clipper handle  70  upon release of the pivot tabs  55  of the newly chosen position  1 ,  2 . The hair clipper  70  is further altered specifically to a back hair trimming tool by choosing the second blade position  2  in the manner described above and attaching the back-reach attachment  112  to the clipper  70 . 
     Referring now to  FIGS. 1 ,  3  and  5 , the blade assembly  40  has dimensions and contouring that are tightly accommodated by the drive end cavity into which it seats, said contouring being described in detail in the sections discussing the handle drive end  71 . In the preferred embodiment the pivotable blade assembly  40  includes a fixed blade  43  and reciprocating blade  44 , a pivot axle  41 ,  42 , housing  50 , a blade actuator having a cam follower  47 , spring means  40  and fastening means  45 , each of said components being integral to the assembly of the pivotable blade assembly  40 . The fastening meant  45  is also contemplated as clips, rivets, tabs or other fastening means that are preferably semi-permanent. 
     Referring now to  FIGS. 1 ,  2 , and  5 , contemplated also for use with the present invention in another embodiment is a safety release means  54  composed of a spring-action rod and barrel combination suitable for attachment to the handle drive end  71  at either of or both of the lateral walls. Said safety release means is contemplated to replace either of or both of the laterally situated safety formations  53 , thus providing the user with additional security against unwanted slippage upward or downward of the blade assembly  40  during operation. Such contemplated embodiment of the present invention preferably necessitates that the user disengage the safety release means  54  by pulling said safety release means out of the dual position formation  62  formed integrally into the housing  50  of the blade assembly, and thus out of the path of said housing allowing said blade assembly to pivot in the manner described above. 
     BLADES 
     Referring now to  FIGS. 5 and 12  and describing the preferred embodiment blades, each blade  43 ,  44  appears rectangular in shape with rounded corners at the posterior non-cutting portion and a plurality of teeth at the anterior cutting portion. The plurality of teeth  44   a  along the anterior edge of the reciprocating blade  44  preferably is greater than that  43   o  along the anterior edge of the fixed blade  43 . The teeth  43   a  of said fixed blade have a greater rake angle than those  44   e  of their counterpart reciprocating blade  44 . Preferably, the teeth  43   a  on the fixed blade  43  are spaced more widely than the teeth  44   e  on the reciprocating blade  44 . Further, the differences in tooth shape and spacing generally provide a more efficient cutting action than when identical tooth patterns are used for both blades. Additionally, the teeth  43   d  at each lateral edge of the fixed blade  43  are rounded, wider and preferably smooth such that irritation scratching or nicking of the akin surface is nullified. The number of teeth and the actual teeth configuration employed will depend on the application of the product and manufacturing requirements. 
     Referring now to  FIGS. 5 and 8 , each blade  43 ,  44  is formed such that there exists a substantially flat sliding surface at the anterior bottom and the posterior bottom of each blade and a slight concavity  43   b ,  44   b  there between. Each blade is formed such that on inverting them and securing them one against the other their flat surfaces slidingly abut and their concavities  43   b ,  44   b  form an appreciable space there between. 
     Referring now to  FIG. 8 , the reciprocating blade  44  is slightly offset laterally toward the posterior edge of the fixed blade  43  (FIG.  8 A). This relative position of the blades is intended to prevent the user from nicking and/or cutting the skin on the body surface being attended and is a relationship between reciprocative blade parts that is well known in the art. The reciprocating blade  44  is assembled upon the blade drive actuator  47  so that the cutting edge extends out the open portion of the anterior of the blade housing  60  (FIG.  8 B), and is inverted relative to the fixed blade  43  to that apace  43   b ,  44   b  is formed between the two blades. However, the opposing toothed edges will be in sliding contact with each other. The blades  43 ,  44  are only partially enclosed by the housing  50  and project from the open side to engage hair to be clipped (FIG.  8 D). 
     Referring now to  FIGS. 5 and 12 , the fixed blade  43  has dimensions such that it is appreciably larger than the reciprocating blade  44 . Bilaterally along the posterior edge of the fixed blade  43  is a threaded hole  43   c  the function of which is to receive a correspondingly threaded fastener  45  intended to secure together the housing  5   o  and inner componentry  43 - 50  of to blade assembly  40 . Concerning the reciprocating blade  44 , said blade has dimensions that relative to the fixed blade  43  are appreciably smaller than would be the convention in the art. Centrally formed on the reciprocating blade  44  is a guide slot  44   c  corresponding to the guide boss  47   o  formed on the blade actuator  47 . Said slot has dimensions that tightly accommodate said guide boss to encourage only sliding movement of and prevent unwanted play in the blades  43 ,  44  during operation. 
     HOUSED COMPONENTRY 
     Referring now is  FIGS. 3 ,  4 ,  6  and  12 , the pivotable blade assembly  40  receives its pivotable motion by way of the pivot axle  41 ,  42  that secures it. At least two forms of safety, and a contemplated third form, are provided toward prevention of unwanted slippage in said pivotable motion by way of the tightly accommodating pivot axle holes  51 , the dual position formations  52 , and the contemplated safety release means  54 . Suctioned air  60  is channeled past the blade boating  50  by its inherent contouring (best seen in FIG.  4 ). Within said blade housing is the blade spring means  48  and the blade actuator  47  having a cam follower  47   b . Also extending into said blade housing is the drive actuator member  89  ( FIG. 3 ) that provides the reciprocal motion to the blades. The fixed blade  43  secures stop the blade housing having preferably two screws  45  extending through its posterior edge into the spring means  48  and housing  50  below. Said spring means supports the blade actuator  47  by way of tightly fitting into the notches  47   c  (best seen in  FIG. 12 ) integrally formed on the bottom or underside of its rectangular extension, which blade actuator  47  supports and guides the reciprocating blade  44  by way of the guide boss  47   a  and integrally formed guide slot  44   c into which it fits. Said reciprocating blade is further supported and held tightly against the fixed blade  43  by way of the spring means  46  applying biasing force there against. 
     Referring now to  FIGS. 5 and 12 , the blade actuator  47  is comprised of several integrally formed components but preferably is a single plastic formation. Said bade actuator has along its top a preferably rectangular extension that is formed substantially flat to tightly fit against the reciprocating blade  44  when said blade is inverted atop it for assembly, and that is long enough to accommodate the reciprocal stroke of and to support said reciprocating blade. Atop said extension is found the centrally located and preferably elongate guide boss  47   a  suitable for stabilizing the sliding actuation of the reciprocating blade  44  by way of a corresponding blade guide slot  44   o  formed centrally in said reciprocating blade to tightly accommodate said guide boss. 
     Referring still to  FIGS. 5 and 12 , the above described rectangular extension of the blade actuator  47  has centrally formed on its bottom bilaterally extended notches  47   c  (best seen in  FIG. 12 ) or spring guides to accommodate slidingly the spring means  46  delivering the biasing force to the cutting blades. Said notches extend laterally in either direction sufficiently to accommodate the reciprocal stroke of said reciprocating blade while traveling along the spring means  46 , said spring means being of a type known in the art to apply a biasing force against the cutting blades and being bilaterally installed and made stationary by screws  45  or other preferably semi-permanent attachment means. Said spring means holds the reciprocating blade  44  tightly against the fixed blade  43  to perform the cutting action. Said spring means also is contoured to fit beneath the reciprocating blade  44  and above the housing  50  while extending around the pivot axle  41 ,  42  such the no appreciable contact or biasing forces exist between said spring means and said pivot axle that would cause either to seize upon engagement into a new pivot position. The guide boss  47   a  slides reciprocally between the spring means  48 , and the integrally formed notches  47   c  of said blade actuator travel along the top of the integrally shaped and stationary spring means  46 . 
     Referring now to  FIGS. 3 ,  5 ,  8 ,  9  and  12 , also located on the bottom of the rectangular extension of the blade actuator  47  is a cam follower  47   b  ( FIG. 5 ) formed to accommodate the actuating motion of the drive actuator member  89  (FIG.  3 ). The cam follower  47   b  ( FIG. 5 ) is shaped and formed to maintain substantial contact with the drive actuator member  89  ( FIG. 3 ) during the arc of pivot  3  (FIG.  8 ), whether the pivotable blade assembly is parked in its first position  1  or in its second position  2  (FIG.  3 ). Said cam follower is slotted in its interior in a manner known in the art to produce only lateral movement of the blade such that on actuation by the drive actuating member  89  of the motor  80  reciprocal motion transfers to the reciprocating blade  44 . Said cam follower transfers reciprocative motion only slidingly to the reciprocating blade  44  by way of the guide boss  47   a  ( FIG. 5 ) and spring notches  47   c  (FIG.  12 ). Said motion coupled with biasing force placed against the blades by the spring means  45  causes the teeth to cut hair. The blade actuator  47  ( FIG. 8B ) is shaped to fit within the interior of the blade housing  50  and also shaped at its posterior edge to loosely accommodate the pivot axle  41 ,  42  (FIG.  8 D). Said cam follower slides reciprocally at the anterior, central portion of the housing  50  and necessarily must not be fitted tightly against said housing thus preventing unwanted friction or possibly diminished performance of the blade assembly  40 . 
     HOUSING 
     Referring now to  FIG. 5  concerning the blade housing  50 , it is known that in the present invention said housing serves to guide suctioned air into the clipper handle and therefore preferably has solidly formed faces at its anterior, posterior and lateral portions. Said housing has an opening at its top face that includes a portion of the anterior face  50   e  suitably formed to accommodate reciprocal motion of the reciprocating blade  44 , is open at the bottom, and is hollow in the interior to accommodate internally housed componentry. Installation of said componentry is accomplished by way of the openings at the top and bottom faces of the housing  50 . 
     Referring now to  FIGS. 1 and 5 , the blade housing  50  preferably is formed of metal or plastic capable of being threaded, or capable of receiving a threaded part or lock washer means to aid in assembly, bilaterally at its posterior top portion  50   f . Said housing has at its posterior top portion  50   f  an integrally formed rectangular portion having preferably threaded holes that serve to receive correspondingly threaded screws  45  upon assembly and serve to support and semi-permanently secure the fixed blade and spring means. Said housing has at its anterior a rectangular recession  50   e  of the anterior wall such that the motion of the reciprocating blade  44  is accommodated there. Said housing has formed in its lateral faces pivot axle holes  51  corresponding to the positions of the pivot axle holes  51  formed in the lateral faces of the handle drive end portion  71  (FIG.  1 ), and said housing also has formed in its lateral faces a dual position formation  52  corresponding to the safety formation  63  formed in the drive end cavity of the handle drive end portion  71  (FIG.  1 ). 
     Referring still to  FIGS. 1 and 5 , said housing preferably also has at each of its most lateral edges of the anterior face a pivot tab  66 . Said tabs extend outward through the bilateral safety venting  61 D to flush with an lateral faces of the handle drive end  71  upon installation of the blade assembly  40 . Said tabs are intended for engaging and disengaging from safety formations  53  ( FIG. 1 ) at each of the parked positions of the blade assembly  40  by way of applied finger pressure as described earlier. A significant advantage of the construction of the pivot tabs  65  and the cam follower  47   b  is that the operator may readily pivot the blade assembly  40  upon the handle drive end portion  11  by merely depressing the pivot tabs  55  and exerting a slight pushing force axially directed upward or downward relative to the blade assembly. There is no special alignment or manipulation required to achieve proper subsequent engagement of the blade assembly upon the handle as it readily reseats itself at the newly chosen pivot angle, and engagement of the cam follower  47   b  upon the drive member  89  is never comprised due to said cam follower&#39;s continuous contact with said drive member during all pivot angles. Also located at the lateral edges of said anterior face preferably is vertical slotting  50   d  allowing the press tabs  55  to more easily depress and disengage the housing  50  from the safety formations  53  for pivot action. The slotting  50   d  has dimensions sufficient to positively affect the intentions of the press tab  65  but the not negatively affect the aerodynamic intention of the housing&#39;s anterior face. 
     GUARD/GAUGES 
     Referring now to  FIGS. 3 and 17 , upon shifting the blade assembly  40  into either of two positions as described previously, the user attaches an appropriate guard/gauge to achieve a predetermined cut length. Preferably all such gauge/gauges are made of plastic material as is conventional in the art with special attention being focused on the potential for rough or angular plastic edges as the discomfort they can cause against the skin surface is undesirable. Preferably all such guard/gauges have formed integrally on their anterior face a male counterpart  77  to the guard/gauge securing means  73  located on the anterior face of the clipper handle  70 , which securing means are both described in the section designated “Handle Drive End Guard/Gauge Securing Means.” 
     Referring now to  FIGS. 15 ,  17 ,  18  and  28 , the guard/gauge  113  specific in cutting the body hair in tight, angular, or niche-like spaces as would be the case in the bikini area, is engineered to fit onto the blade assembly  40  while parked in its second position  2  ( FIG. 15 ) and is shaped to “roll” within a space equivalent to the depth (preferably 1.5 inches) of the clipper  70 , plus is engineered to block the flow of suctioned air  60  into bilateral safety venting  61 D described below in the section “Handle Drive End Safety, Venting.” The benefit of the guard/gauge  113  is the “rolling” motion that allows for cutting and trimming of body hair in areas of the body previously difficult to attend with conventional clipper and guard/gauge trimming systems, as would be the case in the bikini area, plus simultaneous evacuation of clipped hair debris from the skin surface and from the work area into the vacuum hair collection canister  90 . A blow-up view ( FIG. 18 ) of said guard/gauge demonstrates the individual componentry  113   a ,  113   b ,  113   c ,  113   d    113   e ,  77  of the preferred embodiment single molded plastic part dimensioned to a half-inch hair cutting length. 
     Referring now to  FIGS. 19 ,  21 ,  22  and  28 , the guard/gauge  114  specific to cutting the body hair on relatively flat surfaces, as would be the case on the chest or abdomen, is engineered to fit onto the blade assembly  40  while parked in its second position  2  ( FIG. 19 ) and is shaped to “comb” the body surface in a conventional manner, plus is engineered to block the flow of suctioned air  60  into the bilateral safety venting  61 D. The benefit of the guard/gauge  114  is a predetermined cut length utilizing a conventional combing motion when drawn across a relatively flat surface of the body, such as the chest or abdomen, at an angle most notably anticipated for the users self, plus simultaneous evacuation of clipped hair debris from the skin surface and from the work area into the vacuum hair collection canister  90 . A blow-up view ( FIG. 22 ) of said guard/gauge demonstrates the individual componentry  114   a ,  114   b ,  114   c ,  114   d ,  114   e ,  77  of the preferred embodiment single, molded plastic part dimensioned to a half-inch hair cutting length. 
     Referring now to  FIGS. 23 ,  25 ,  26  and  28 , the guard/gauge  115  specific to cutting the head hair is engineered to fit onto the blade assembly  40  while parked in its first position  1  ( FIG. 23 ) and is elongate and comb shaped to reflect a standard wall known in the art, plus is engineered to block the flow of suctioned air into the bilateral safety venting  61 D. The benefit of the guard/gauge  115  is a predetermined cut length utilizing conventional motions for cutting hair on the head while simultaneously evacuating clipped hair debris from the scalp surface and from the work area into the vacuum hair collection canister  90 . A blow-up view ( FIG. 25 ) of said guard/gauge demonstrates the individual componentry  115   a ,  115   b ,  115   c ,  115   d ,  115   e ,  77  of the preferred embodiment single, molded plastic part dimensioned to a half-inch hair cutting length. 
     SKIN GUARD 
     Referring now to  FIGS. 16 ,  20 ,  24  and  28 , the present invention attachment designated the skin guard SG 1  is similar in material, function, and method of installation to the above described guard/gauges. The skin guard SG 1 , however, is designed to offer a skin-close cut of the hair plus prevent skin surface from coming into contact by suctioned force with the cutting portion of the blade assembly  40 , while simultaneously evacuating clipped hair debris from the skin surface and from the work area into the vacuum hair collection canister  90 . 
     Referring now to  FIGS. 20 and 24 , the preferred embodiment skin guard SG 1  is demonstrated as being for use with the first position  1  pivotable blade position. As such, the exterior, lateral view of said skin guard ( FIG. 20 ) provides a straight edge along its apex that is substantially flush with the fixed blade tooth rake angle. This straight edge along the posterior portion of the apex provides the user with a means of most efficient positioning of the blades relative to the skin surface during the skin-close cutting technique. Additionally, the straight edge along the anterior portion of the apex provides the user with a means for applying the cutting portion of the blade assembly  40  directly to the skin for applications such as trimming the hair line at the base of the neck. At the anterior portion of the skin guard SG 1  is an opening sufficient in volume to accommodate optimum intake of the suctioned airflow  60 . Also at its anterior is a guard/gauge securing means  77  of the type referred to above in the section designated “Guard/Gauges.” 
     Referring still to  FIGS. 20 and 24 , an anticipated variation to the preferred embodiment skin guard SG 1  is alteration to its design sufficient for accommodating the second position  2  (not shown) of the pivotable blade assembly  40  to similar end and intention of skin-close hair cutting technique. A blow-up view ( FIG. 24 ) of the skin guard SG 1  demonstrates the individual componentry SGa, SGb, SGc, SGd,  77  of the preferred embodiment single, molded plastic part dimensioned to a skin-close hair cutting length. 
     BACK-REACH ATTACHMENT 
     Referring now to  FIGS. 27 and 27A , in the preferred embodiment present invention back-reach attachment  112 , the collar  112   a  is demonstrated as having dimensions approximating a one-eighth-inch wall thickness. Horizontally centered on an apex and base of the collar  112   a  are two threaded portions  112   b ,  112   c  sufficient in dimension to receive correspondingly threaded rods  112   d ,  112   e  (FIG.  27 A). Said rods preferably are sufficient in length such that they can be readily stored in the storage compartments of the invention, and such that they provide adequate reach when used to extend the clipper  70  to difficult-to-reach body areas such as the back. 
     Referring now to  FIG. 27A , the preferred embodiment back-reach attachment rod and collar system is demonstrated as having eight distinct methods for attachment to the clipper  70 . Formed on the collar  112   a  are the threaded insert portions  112   b ,  112   c  intended for rod attachment. By forming said insert portions axially, the collar can be installed on the clipper unit (FIG.  27 AE) and then installed in the reverse direction (FIGS.  27 AA,  27 AB) to provide different positioning, and consequently different balance and leverage, in the user&#39;s hand. By varying the angle of the threaded inserts  112   b ,  112   c  on the top and the bottom of the collar  112   a , said collar can be flipped (FIGS.  27 AC,  27 AD) on installation to provide still different balance and leverage. 
     Referring now to  FIGS. 1 and 27 , by forming integrally on the anterior and posterior faces of the clipper handle  70  and the corresponding interior of the collar  112   a  stop means  112   g ,  112   f  that preferably comprises correspondingly male and female nodules and concavities or holes, further variations of the previously described balance and leverage positions can be achieved. Said variations are achieved by adjusting the collar upward or downward along the body of the clipper handle  70  to engage each of the collar stop means nodules  112   g  provided along the clipper handle  70 . The preferred embodiment back-reach attachment has two sets of corresponding stop means nodules  112   g  and stop means concavities or holes  112   f  plus two differently angled inserts  112   b ,  112   c  providing a total of sixteen distinct methods of attachment. Such variations in attachment method provide the invention with subtle variations to the back-reach attachment  112  as though sixteen differing suction attachments  112  were present for use. This adjustive intention provides the user with a greater degree of control and comfort in choosing which attachment method is most suitable for the given hair cutting task. 
     Referring now to  FIG. 27A , the back-reach extension rods  112   d ,  112   e  are threaded in such a way that they combine to form an elongate rod having sufficient extension capability and having a preferably balled top and to aid in the prevention of slippage from the grasp during use of the attachment  112 . Also said rods are sufficient in diameter and material to offer rigidity and stability within the collar inserts  112   b ,  112   c , said inserts being also of sufficient diameter and material to offer rigidity and stability to said extension rods. The back-reach attachment  112  is installed on the clipper  70  (FIG.  27 AE) in a specific order. First, the collar portion  112   a  is slidingly installed over the blade assembly  40  and onto the clipper handle  70 , next the collar can be adjusted upward or downward on the clipper handle to change leverage, and finally both of the extender rods  112   d ,  112   e  can thread into the chosen collar insert  112   b ,  112   c.    
     This preferred embodiment collar and rod method of attachment provides the back-reach attachment rod portion  112   d ,  112   e , or “handle,” with a secure means of installation that is rigid and stabilizing at the clipper  70  and also provides subtle variations to its angle of attachment for maximum user comfort and control. Such rigidity and stability offer the user ultimate control and optimum functionality of the back-reach attachment  112 , especially when a light-weight and rigid material such as impact-resistant molded polymeric or plastic material known in the art is used in its construction. A contemplated different form of attachment of the rod portion  112   d ,  112   a  to the clipper  70  is a female receptacle integrally formed along the clipper handle  70  such that a correspondingly male insert at the tip of the rod portion  112   d ,  112   e  can be inserted directly into the clipper handle  70 , again achieving a secure means of installation that is rigid and stabilizing at the clipper  70 . 
     It remains preferable, however, to provide the user with varied angles of installation that will help to achieve an anticipated cut length in a safe, controlled and comfortable manner. For example, upon inserting the rod portion  112   d ,  112   e  directly into the clipper handle  70 , angling the male rod tips and female inserts can provide subtle variations beneficial to the users preference and physical abilities, such as physical agility or dexterity. Simple designs will yield the best results, and one complication of the back-reach attachment  112  design will negatively impact rigidity, stability, comfort and control for the user. In achieving various design methods, the rod portion  112   d ,  112   e , or “handle,” of the back-reach attachment  112  should be shaped and angled to provide maximum utility, safety, comfort and control for its user. No matter the alterations to attachment means of the preferred embodiment present invention however, the scope of its substantive part back-reach attachment  112  remains unchanged, and that is to provide the user with a means for making extensible the clipper  70  and for safely reaching the clipper  70  to otherwise difficult-to-reach surfaces of the body. 
     Referring now to  FIGS. 1 ,  27  and  27 A, the benefit of the back-reach attachment  112  in the present invention is a great many variations in balance, leverage and extensible reach achieved with a minimum number of parts and complexity. With such an attachment  112 , any body area or body surface is reachable while utilizing are clipper  70 . 
     Additional embodiments of the back-reach attachment  112  are contemplated as any handle inserted directly into the clipper  70  but not into a collar  112   a  that is attached to the clipper  70 . Generally, however, no matter the embodiment, the user will require a handle having a rigid and stabilizing means of installation at the clipper  70  in order to control the positioning of the blade assembly  40  against the body surface, and a handle that is sufficiently light-weight as to provide the user with comfort and control during its operation. 
     CLIPPER HANDLE 
     Referring now to  FIGS. 2 and 3 , an electric hair clipper of the type suitable for use in the present invention is generally designated  70  and includes a handle drive end portion  71 , a handle motor house portion  72 , a handle butt portion  73  opposite the drive end, and a motor  80  and switch  83  located there between. More specifically, the clipper handle  70  comprises: the handle drive end portion  71  including the first suction formation  61 A and bilateral safety venting  51 D; the handle motor house portion  72  including the second suction formation  61 B, and including the motor housing  81  having a motor  80  and switch  83  located therein; and the handle butt portion  73  opposite the drive end including the formation suitable for suction hose connection  61 C. The clipper handle  70 , including its suction formations  61 A,  61 B,  61 C,  61 D and motor house  81 , is formed preferably of durable, impact-resistant molded polymeric or plastic material as is known in the art. Also preferable is a blade assembly  40  (best seen in  FIG. 3 ) that is pivotable to at least two positions  1 ,  2  for cutting hair and that is integrally designed to direct suctioned air  60  and clipped hair debris into the first suction formation  61 A for subsequent evacuation through the clipper handle  70  by way of the suction hose  66 . 
     HANDLE DRIVE END FLOOR 
     Referring now to  FIGS. 1 and 9 , the floor  74  of the drive end cavity is substantially flat and rectangular in shape, having a depth of approximately five sixteenths inch and a width of approximately two inches, and having a location in relation to the vertical axis of the clipper  70  that is slightly abaxial toward the posterior face of the clipper  70 . Said floor is preferably conjoined or abutted along its four sides with relatively high walls thus creating the drive end cavity. Said walls are contoured specially to accommodate the full 35-degree arc of pivot  3  ( FIG. 9 ) of the pivotable blade assembly  40  that is secured therein by means described in the section designated “Pivotable Blade Assembly.” 
     Referring now to  FIG. 1 , the floor  74  comprises an opening DE 1  at the center of its anterior side sufficient to accommodate the offset cam eccentric  87  and drive actuator member  89  that both preferably extend upward there through said floor, and that are both also slightly abaxial toward the posterior face of the clipper  70 . More specifically, the relatively high and specially contoured interior walls of the drive end cavity are each preferably conjoined with their respective face of the clipper  70 . In other words, the walls that create the specialty contoured drive end cavity extend toward their respective faces of the clipper  70  preferably as solidly molded material of the type previously described and therefore integrally comprise all of or part of said faces at the portion known as the handle drive end  71 . 
     Referring now to  FIGS. 1 ,  2  and  4 , in contrast with the solidly molded material referenced in the previous paragraph are the bilateral edges of only that portion of the drive end cavity that is the first suction formation  61 A. Necessarily, said formation does not conjoin at either of its left lateral or right lateral edges with either respective face of the clipper  70 . Rather, said edges preferably conjoin with their respective sides of the clipper motor house  81  ( FIG. 2 ) atop which the first suction formation  61 A is located. This first suction formation  61 A is a portion of the handle drive end  71  that is more specifically described below in the section designated “Handle Drive End Anterior Wall.” Said portion creates a hollow  61 A,  61 B upon installation of the blade assembly  40 , which is preferably integrally designed with said portion to fit tightly. Said hollow serves integrally to create the continuous main suction formation  61 A  61 B,  61 C formed integrally in the clipper  70 . 
     HANDLE DRIVE END LATERAL WALLS 
     Referring now to  FIGS. 1 and 2  and concerning the preferred embodiment lateral walls of the drive end cavity, ascending from and preferably partially conjoined with the rectangular floor  74  on its two short sides (best seen in  FIG. 1 ) are opposing walls that are substantially vertical and create the interior “sides” of the integrally formed drive end cavity. These two lateral walls extend upward to form the apex of the handle drive end  71  and preferably are substantially flush with and integrally formed with the pivotable blade assembly  40  when parked in its second position  2  (FIG.  2 ). The left interior wall of the drive end cavity is conjoined with the left lateral face of the clipper  70  and also conjoined with the left side of the rectangular floor  74 . The right interior wall of the drive end cavity preferably is conjoined with the right lateral face of the clipper  70  and also conjoined with the right side of the rectangular floor  74 . 
     Referring still to  FIGS. 1 and 2 , when viewed from within the interior of the drive end cavity, each of the lateral walls appears as a solid plane having a substantially vertical rise that forms a contoured apex and spans the depth of the drive end cavity. Each of said walls preferably has formed integrally onto itself a pivot axle hole  51  and a safety formation  53 . The apex of the clipper handle  71  preferably is rounded (best seen in  FIG. 1 ) to be substantially smooth and flush with the “top” of the blade assembly  40  when parked in its second position  2  (best seen in FIG.  2 ), thus providing the user with substantial skin protection and comfort should the user utilize the clipper system while the reciprocating blades are in operation and without the protection area guard/gauge. 
     HANDLE DRIVE END POSTERIOR WALL 
     Referring now to  FIGS. 1 ,  3  and  9  and concerning the posterior wall DE 2 ,  79  of the drive end cavity, this wall ascends from the floor  74  and is inclined at a slight angle designed integrally with the shape of the posterior of the blade assembly  40  while parked in its second position  2  (best seen in FIG.  9 ). The uppermost portion  79  of said posterior wall of the drive end cavity is sharply angled outward and toward the posterior face of the clipper handle  70  to accommodate the first position  1  pivot of the pivotable blade assembly  40  (best avert in FIG.  9 ). When viewed from within the interior of the drive end cavity, the posterior wall DE 2 ,  79  appears as a solid surface comprised or two intersecting planes DE 2 ,  79  spanning the width of the drive end cavity. The slopes of said planes are determined by the 35-degrees arc of pivot  3  ( FIG. 9 ) of the pivotable blade assembly  40  in that the entirety at the posterior wall DE 2 ,  79  preferably tightly accommodates the pivot action of said blade assembly. The preferably close tolerance or tight fit between the posterior wall DE 2 ,  79  and the pivotable blade assembly  40  ( FIG. 9 ) ensures an integral pivot arc stop means  79  (best seen in  FIG. 3 ) for the arc of pivot  3  ( FIG. 9 ) associated with the blade assembly  44 , thus providing safety for the user and enhancing the functionality of the pivotable blade assembly  40  by ensuring that substantial contact is maintained between the pivotable blade assembly  40  and the drive actuator member  89  during any of the pivot action of said blade assembly. This posterior wall DE 2 ,  79  of the drive end cavity is preferably conjoined with the posterior face of the clipper handle  70  and also conjoined with the posterior side of the rectangular floor  74 . 
     HANDLE DRIVE END ANTERIOR WALL 
     Referring now to  FIGS. 1 and 3  and concerning the frusts-pyramidal portion, or pyramid-like portion, of the anterior wall  61 A, DE 3  ( FIG. 1 ) of the drive end cavity, said portion  61 A preferably is integrally shaped to accommodate the full pivotable motion of the blade assembly  40  ( FIG. 3 ) and to accommodate the offset cam eccentric  87  and drive actuator member  89  preferably extending through the drive end floor  74  (best seen in FIG.  1 ). Said portion  81 A is deeply angled on ascent from the drive end floor  74  toward the anterior of the clipper handle  70  (best seen in FIG.  3 ). More specifically, the ascent of said portion  61 A of the drive end cavity rises to a height approximately half the height of the blade assembly  40  whereupon the slope of said portion abruptly increases to mimic the anterior face of the housing of the blade assembly  40  and continues to a height just beneath the bottom blade of the blade assembly  40  (best seen in FIG.  3 ). 
     Referring now to  FIGS. 1 ,  3 ,  7  and  9 , the slopes of the pyramid-like portion  61 A (best seen in  FIG. 1 ) are determined by its lateral, posterior edges (best seen in FIG.  3 ). Said slopes preferably are also determined by the anterior contouring of the housing  50  of the pivotable blade assembly  40  (best seen in  FIG. 7 ) such that the posterior slopes of said portion  61 A preferably tightly accommodate the anterior contouring of the pivotable blade assembly  40  during the entire 38-degree arc of pivot  3  ( FIG. 9 ) associated therewith. 
     Referring now to  FIGS. 3 ,  7  and  9 , the preferably tight tolerance or fit between the frusta-pyramidal portion  61 A and the pivotable blade assembly  40  enhances the aerodynamics of the first suction formation  61 A in that the housing  50  ( FIG. 7 ) of the blade assembly  40  serves to directionally guide suctioned air  60  into said formation. Said tight tolerance also enhances the ability of the relationship between the first suction formation  61 A and the blade assembly  40  to extremely limit the volume of suctioned air  60  to a substantially focused point or intake at the cutting blades of the pivotable blade assembly  40  whether a is parked in its first position  1  or parked in its second position  2 . Therefore, it is known that during manufacture and assembly minimized tolerance between the blade assembly  40  and the first suction formation  61 A against which it is secured, as opposed to a large gap that would cause inefficiency, provides generally superior suction of the cutting portion of the blade assembly  40 . 
     Referring now to  FIGS. 1 ,  2 ,  3  and  9 , the anterior wall  61 A, DE 3  of the drive end cavity in its entirety includes a “rise” that when viewed frontally as a cutaway  61 A (best seen in  FIG. 2 ) is preferably triangular with a flattened apex having a width of approximately three-sixteenths inch at its apex and having a width of approximately one and one-quarter inches at its basal intersection with the plane of the drive end floor  74 . When the preferred embodiment of said rise is viewed laterally as a cut-away (best seen in  FIG. 3 ) it is polygonal in shape having a depth of approximately five-sixteenths inch at the apex and at the midpoint and having a depth of approximately nine-sixteenths inch at its basal intersection with the plane of the drive floor  74 . It is known that the notably polygonal shape at the lateral edges of the first suction formation  81 A (best seen in  FIGS. 3 and 9 ) serves to channel and redirect air suctioned from the cutting portion of the blade assembly  40  in a bilaterally deferred manner toward the vertically central but laterally exterior portions of the clipper  70 . Said rise is preferably molded as a solid formation but contemplated also as a hollow formation with no appreciable difference in performance. 
     Referring now to  FIGS. 1 , and  3 , the “rise”  61 A referenced in the above paragraph (best seen in  FIG. 1 ) comprises the most interior portion of the anterior wall  61 A, DE 3 , and is the portion designated the first suction formation  61 A. Said formation is not conjoined with the anterior side of the rectangular floor  74  as preferably an injection mold seam exists there. Said formation preferably is conjoined with the most exterior portion DC 3  of the anterior wall of the drive end cavity, and preferably is conjoined also with the anterior face of the clipper handle  70 . 
     Referring now to  FIGS. 1 ,  3  and  4 , when viewed from within the interior of the drive end cavity, the most interior portion  61 A of the alliance wall  61 A, DE 3  appears as a frusta-pyramidal shape  61 A having two distinct slopes intersecting concavely at a midline that is parallel with the floor  74  of the drive end cavity, said shape being abutted and preferably conjoined to a wall-like structure DE 3  there behind. Furthermore, the frusta-pyramidal shape  61 A projects inwardly from the wall-like structure DE 3  toward the interior of the drive end cavity. It is known that the first suction formation  61 A, has an integral relationship with the contoured housing  50  of the pivotable blade assembly  40  (FIG.  4 ), each functioning in conjunction with the other to streamline suctioned air into the second suction formation  61 B whereupon it is deferred onward toward evacuation from the clipper handle  70 . 
     Referring now to  FIG. 1 , the preferred embodiment frusta-pyramidal shaped rise  61 A conjoins with a more wall-like structure DE 3  of substantially vertical slope ascending behind said rise  61 A to a height that is substantially flush with the apex of said rise  61 A. The slope of said wall-like structure DE 3  is determined by the angle at which the frusta-pyramidal shape  61 A descends from its apex toward the abutted edges or two preferably rectangular shaped hollows  61 B that are bilaterally adjacent to its base. Each of said hollows  61 B abuts the anterior wall DE 3  at opposing sides of said wall, each also abuts its respective left or right lateral wall of the interior of the drive end cavity, and each also abuts opposing ends of the anterior of the rectangular floor  74  whereupon preferably an injection mold seam is found. Each of said hollows integrally comprises the entrance to the bilateral conduits that are the second suction formation  61 B. 
     HANDLE DRIVE END SAFETY VENTING 
     Referring now to  FIGS. 1 and 3 , bilateral safety venting  61 D is comprised of bilateral holes formed integrally in both lateral force of the clipper handle drive end  71  (best seen in FIG.  1 ), said holes preferably formed as a polygonal shape mimicking the polygonal shape described previously as the lateral view of the first suction formation  61 A. In the preferred embodiment, said polygonal shape is suitable in dimension for at least halving the optimum intake of the clipper  70 . More specifically, the present invention includes bilateral safely venting  61 D the function of which is nullified by use of a guard/gauge such that said guard/gauge installed on the clipper handle  70  blocks the draw of suctioned air  60  through said safety venting thus promoting a maximum flow of suctioned air  60  across the cutting portion of the blade assembly  40  and into the first suction formation  61 A. 
     Referring now to  FIGS. 1 and 4 , in the preferred embodiment of the present invention pivotable blade hair clipper and suction collection system the inner volume of all suction componentry is contemplated and designed such that the present invention has as its smallest suction component, with respect to inner volume, the second suction formation  61 B. Said inner volume is calculable and preferably all other integrally functioning suction components are sufficient in their size and shape to at least equal the optimum intake of said formation. More specifically, each of the two holes comprising the bilateral safety venting  61 D is sufficient in size and shape to at best halve the optimum intake of suctioned air  60  through the clipper  70 , thus beneficially deterring in its entirety the suctioned intake at the cutting portion of the blade assembly  40  until such time as a guard/gauge is installed on the clipper  70 , and thus providing the user with an optimal safety precaution to prevent unwanted draw by suctioned force of the skin surface into the cutting blades. 
     HANDLE DRIVE END SAFETY FORMATION 
     Referring now to  FIGS. 1 ,  2 ,  3 , and  6 , the lateral walls of the clipper handle drive end  71  have located bilaterally thereon a safety formation  53  that readily engages a corresponding dual position formation  52  ( FIG. 6 ) located on each of the lateral exteriors of the pivotable blade assembly  40 . The safety formation  63  is bilaterally symmetrical and comprises a raised nodule located on each of the lateral interior walls at the drive end cavity, said nodule serving as a male part. The safety formation  53 , or nodule, corresponds with and is positioned integrally with the holes comprising the duel position formation  62  (FIG.  6 ). The dual position formation  52  is comprised of holes, but also is contemplated as concavities rather than holes. Said dual position formation functions as a female counterpart to tightly accommodate the safety formation  53  formed in the handle drive end  71 . Said safety formation  53  functions to tightly park the pivotable blade assembly  40  into one of its two positions  1 ,  2  by engaging the dual position formation  62  at either of both of sold positions. 
     HANDLE DRIVE END GUARD/GAUGE SECURING MEANS 
     Referring now to  FIGS. 3 ,  16 ,  17 ,  21  and  26 , in the preferred embodiment of the present invention, a clipper handle guard/gauge securing means  75  is located on and preferably molded integrally with the anterior face of the handle drive end portion  71 . Said securing means  75  corresponds integrally with respect to position and formation to the guard/gauge securing means  77  on the guard/gauge  113 ,  114 ,  116 , as referenced previously in the section designated “Guard/Gauges,” and on the skin guard SG 1  as referenced previously in the suction designated “Skin Guard.” 
     Referring now to  FIGS. 1 ,  3  and  17  the function of the clipper handle guard/gauge securing means  75  ( FIG. 3 ) and the corresponding and preferably tightly fitting guard/gauge securing means  77  ( FIG. 17 ) is to prevent unwanted slippage of the guard/gauge  113  while installed an the handle drive end  71 . 
     Additionally, at the junction of the handle drive end  71  and the handle motor house  72  preferably is formed integrally on the anterior and posterior faces of the clipper  70  a lip, or ridge, or shelf, or other means designated the clipper handle guard/gauge stop means  76  (best seen in FIGS.  1  and  3 ). The function of the clipper handle guard/gauge stop means  78  is to provide a stop point when installing the guard/gauge on the handle drive end  71 . 
     Referring now to  FIGS. 3 ,  10 ,  17 ,  21  and  25 , in its preferred embodiment the present invention clipper handle guard/gauge security means  76  comprises an elongate concavity substantially centered horizontally on this anterior face of the handle drive end portion  71 , parallel to the plane of the floor  74  of the handle drive end  71 , and approximately one fourth the width of the clipper  70 . Said securing means  75  is preferably positioned vertically approximately one-quarter inch above the plane at the floor  74  of the handle drive end. Furthermore, the guard/gauge securing means  77  located on the guard/gauges  113 ,  114 ,  115  and skin guard SG 1  is preferably formed convex and elongate corresponding as a tightly fitting male counterpart to the concavely formed securing means  75  described above. Each of said female and male securing means  75 ,  77  preferably is integrally designed with its counterpart securing means with respect to shape, dimension, position and function. 
     HANDLE DRIVE END PIVOT AXLE COMPONENTRY 
     Referring now to  FIGS. 1 ,  3 ,  6  and  9 , in the preferred embodiment of the present invention preferably formed integrally in each of the lateral walls of the handle drive end portion  71  is a bilaterally symmetrical pivot axle hole  51  that functions to tightly secure a preferably threaded pivot axle male part  42  into a preferably correspondingly threaded pivot axle female part  41  by insertion through said axle hole formed on the handle drive end portion  71 , then through the corresponding bilaterally symmetrical pivot axle hole  51  in the pivotable blade assembly  40 , and then threading the parts together. 
     Referring now to  FIG. 9 , in the preferred embodiment of the present invention the pivot axle location is precisely centered in a 360-degree arc, or circle, designated the arc of pivot  3 . In the preferred embodiment said arc functionally spans thirty-five degrees. Also in the preferred embodiment the pivot axle hole  51  is precisely located and configured to tightly accommodate a one-eighth inch diameter axle. 
     Referring now to  FIGS. 3 ,  6  and  9 , the preferred embodiment pivotable blade  40  assembly can be pivoted within the drive end cavity around only one horizontally oriented axis, said axis determining precisely the position of the pivot axle hole  51  in each of the handle drive end  71  and the housing  50  of the blade assembly  40 . In the preferred embodiment of the present invention, the pivot axle hole  51  in each of the lateral walls of the drive end  71  exactly corresponds to the pivot axle hole  51  in the corresponding lateral wall of the pivotable blade assembly  40  with respect to position and dimension. Additional variances or tolerances in forming the pivot axle hole  51  preferably are extremely minimized thus making the pivotable motion of the blade assembly  40  precise and stable. 
     HANDLE MOTOR HOUSE PORTION 
     Referring now to  FIGS. 2 and 28 , in the preferred embodiment the clipper motor  80  is housed within the motor house  81  in such a way that airflow  60  is suctioned around the motor house  81  by way of the designated second suction formation  61  thus allowing clipped hair debris to pass through the clipper unit  70  while not affecting motor operation and still achieving the smallest size clipper unit possible. Furthermore, the motor shell  88  is integrally designed with a cam eccentric  87  and drive actuator member  89  that extend upward through the floor  74  of the drive end  71 , thus the preferably rotary clipper motor  80  provides reciprocative motion to the blade assembly  40  there secured. The arrangement and operation of the motor  80 , the drive shaft  88 , the cam eccentric  87  and the drive actuator member  89  are similar to rotary motor componentry which is well known in the art. Said rotary motor componentry comprises the preferred embodiment motor componentry of the present invention especially because such a rotary-type motor provides the user with a more comfortable clipper handle shape, as well as generally less weight, noise and vibration, then does its electromagnetic counterpart. Said motor is preferably of the rotary type but is also contemplated as the electromagnetic type. 
     Referring now to  FIG. 28 , the preferred embodiment motor  80  is powered by electrically drawing on vacuum motor wiring  104  in a known way  91 . This known method  91  of wiring  104  is also described as a supply  104  powering the vacuum motor  100 , which supply  104 ,  84  also travels through the interior of the suction base  66  to supply the clipper motor  80 . In its preferred embodiment, this anticipated means of powering the clipper  70  enables a removable electrical power supply cord designated  84  with male  85 ,  105  and female  86 ,  106  connection to pass from the vacuum motor house  101  to the clipper motor house  81  by way of the interior of the suction hoses  66  and provides maximum clipper mobility while the clipper  70  is in operation. The detachable power supply cord  64  is equally well described as power supply wiring  84  traveling within or housed fixedly within the suction hose  66 , having subsequent wiring connectors  85 ,  105  at each of its ends. Preferably a power supply cord  84  connected to and powered by the vacuum hair collection canister  90  in a known manner  91 , by the use of engaging connection  85 ,  105 ,  86 ,  108 , travels internally from end to end of the suction hose  66  to power the motor switch  83  and motor  80  located within the clipper motor housing  81 . Contemplated, however, is an alternative embodiment wherein said wiring is external to the suction hose  66  and attached thereto by clips (contemplated, but not shown), but such method appreciably hinders clipper mobility in that an external hose and an external cord are now both present during operation of the clipper  70  as opposed to the preferred embodiment wherein only an external hose is present. 
     Referring now to  FIGS. 2 and 28 , the motor  80  is wired by means known in the art to a switch  83  and to a connector preferably of female design  88  that engages a corresponding male connector  85  such that an electrical supply cord  84 , attached to said male connector extends out of the clipper handle butt portion  73 . Said supply cord preferably extends onward by way of the interior of the suction hose  66  toward a similar means of electrical connection  105 ,  106  within the vacuum hair collection canister  90 . The preferred embodiment means for wiring both the clipper motor  80  and the vacuum motor  100  are well known in the art and are intended to originate from the same power source thus allowing the user to provide a power supply to the present invention by way of a single electrical outlet though alternative means of powering the invention are contemplated as well including, but not limited only to, rechargeable batteries for powering the clipper motor  80 . It a known that in a contemplated embodiment clipper handle  70  having rechargeable means of operation, for example such battery pack componentry is insufficient to operate the clipper motor  80  for extended periods of time and negatively affects ergonomic balance and optimum size of the clipper handle  70 . 
     Referring now to  FIGS. 1 ,  2  and  3 , when viewed from the front, the preferred embodiment motor house  81  appears symmetrical and centrally located, and is preferably formed as a six sided continuous wall of sufficient dimensions to house the motor  80  (best seen in FIG.  2 ). When viewed from the side, at the junction of the handle drive end portion  71  and the handle motor house portion  72  preferably a formed integrally on the anterior and posterior faces of the clipper  70  a substantially flat lip, or ridge, or shelf or other means designated the clipper handle guard/gauge stop means  78  (best seen in FIGS.  1  and  3 ). The function of the clipper handle guard/gauge stop means  78  is to provide a stop point when installing the guard/gauge on the handle drive end  71 . 
     Referring now to  FIG. 2 , the motor house  01  preferably is formed integrally into the handle portion of the clipper  70  and made of durable, impact-resistant molded polymeric or plastic material as is known in the art such that seams or joints inherent in the injection molding process are minimized and do not inherently interfere with the aerodynamics of the main suction formation  61 A, or do not interfere more specifically with the function of the second suction formation  61 B that is integrally a part of the motor house  81 . The dimensions and configuration of said second suction formation are sufficient for passing through itself a volume of air intended for evacuation of clipped hair debris from the cutting portion of the blade assembly  40  through the clipper handle  70  and then onward by way of a suction hose  66  toward final evacuation. 
     Referring still to  FIG. 2 , a break in wall continuity exists at the apex of the motor house  81  as a preferably round hole dimensioned and located to allow the extension of the drive actuator member  89  through the floor  74  of the drive end  71 . Also, a break exists in the base of the otherwise preferably continuous six-sided wall of the motor house  81 . The basal break preferably is a round hole sufficient in dimension and shape for passing through itself and securing into the hollow interior of the motor house  81  electrical componentry associated with and intended for powering the clipper motor  80 . More specifically, the preferred embodiment motor house  81  has mounted in a hole in its base a female connector  88 . Additionally, ventilation is present in the form of small holes (not shown) located basically in the motor house walls. The preferably continuously molded form of the motor house  81 , excepting the holes described, contributes to the efficiency of the vacuum suction capability of the present invention pivotable blade hair clipper and suction collection system by preventing the draw of airflow  68  and clipped hair debris from passing into the motor house and by streamlining said airflow and clipped hair debris around the motor house  81  and onward to the suction hose  66  toward final evacuation. 
     Referring still to  FIG. 2 , in the present invention the preferred method of mounting a power supply connector of preferably female design  88  to the interior of the motor house  81  is to insert said female connector into said motor house by way of the preferably hole-shaped wall break that exists in the base of said motor house. Said female connector preferably is mounted and secured were by a connector mounting means  82  such as a neoprene fitting or other means known in the art. Also, said female connector preferably protrudes from the base of the motor house  81  sufficiently to engage its corresponding male connector  85 , and is sufficiently stable and strong and secure for the user to engage upon it said male connector without dislodging it or otherwise compromising the intentions of the preferred method of power supply. Similarly, the preferred method for mounting the motor  80  within the interior of the motor house  81  is accomplished by means known in the art and by means that will prevent user access to said motor and its associated electrical componentry, excepting the preferably female connector  85  and switch  83 , under normal operating conditions. 
     Referring now to  FIGS. 1 and 2 , the preferred embodiment motor switch  83  is located below the motor  80  within the triangular shaped hollow specifically accommodating electrical wiring componentry associated therewith. As demonstrated in  FIG. 1 , the switch has only simple “ON/OFF” designation, said switch preferably being wired by means know in the art to the main switch located near the vacuum motor housing as described in the section designated “Vacuum Canister.” The clipper motor switch  83  preferably protrudes through the posterior face at the clipper  70  ( FIG. 1 ) for user access. 
     HANDLE BUTT PORTION 
     Referring now to  FIGS. 2 and 3 , the present invention pivotable blade hair clipper and suction connection system includes a clipper handle butt portion  73  having a formation suitable for suction base connection  61 C and for final evacuation of suctioned airflow  60  from the clipper handle  75 . More specifically, the clipper handle butt portion  73  serves to join the bilaterally halved second suction formation  61 B in a manner suitable for suction hose connection. Viewed from the side (best seen in FIG.  3 ), the interior of the clipper contains substantially hollow space  61 C inherently formed by its motor house  81  and the injection molded plastic material comprising the faces of said clipper. Viewed from the front (best seen in FIG.  2 ), said motor house and said faces of the clipper form a substantially hollow space also such that the second suction formation  61 B is deferred bilaterally into a single hollow formation  61 C and onward to the suction hose  66 . 
     Referring now to  FIGS. 2 and 3 , the preferred embodiment clipper handle  70  has within the formation  61 C ample space for the user to readily engage the male connector  85  into, or readily disengage it from, the corresponding female connector  86  secured at the base of the motor house  81 . Additionally, the handle butt portion  73  is integrally formed as a tubular extension having on it connector clips  63  such that a correspondingly formed fitting or connector  62  made preferably of flexible rubber can be installed thereupon and secured by means of the clips  63 . Said clips preferably comprise a smooth and rounded ridge sufficient in shape, dimension and location for ideal engagement and disengagement of the correspondingly formed rubber connector  62 . 
     Referring now to  FIGS. 2 ,  3  and  28 , said tubular extension preferably is sufficient in its height (best seen in  FIG. 2 ) to extend the suction hose  66  away from the clipper handle  70  such that ergonomic balance or leverage can be maintained, complementary to the necessarily downward force of gravity applied by the weight of the suction hose against the clipper handle  70 , under conditions of normal operation in the user&#39;s hand. Unlike some prior art clipper handles, the preferred embodiment clipper handle  70  of the present invention evenly distributes its weight and offsetting gravitational forces to provide the user with a feeling of balance and control while utilizing the invention. Furthermore, in the preferred embodiment the tubular extension has an approximate diameter of three-quarters inch and is sufficient in volume to accommodate the optimum intake of the vacuum motor  100  (FIG.  26 ). Thus, is provided the means for attaching the suction hose  66  to the clipper handle butt portion  73 . 
     SUCTION HOSE 
     Referring now to  FIGS. 2 ,  13 ,  14  and  28 , in the preferred embodiment of the present invention the suction hose  66  preferably is made of light gauge wire and vinyl or other materials known in the art for their very high flexibility and light weight. The detachable power supply cord  84  is equally well described as power supply wiring  64  traveling within or housed fixedly within the suction hose  66 , having subsequent wiring connectors  83 ,  105  at each of its ends. Additionally, the preferred embodiment suction hose has an appreciably large inner diameter not less than three-quarters inch and is highly flexible such that, as described previously, a removable electrical power supply cord  84  travels from and to and within it. Such method is intended to provide maximum mobility and ergonomic balance of the clipper  70  under conditions of normal operation in the user&#39;s hand. 
     Referring now to  FIGS. 2 ,  13  and  14 , the preferred embodiment suction hose  66  is connected at either end to each of both the clipper  70  at its butt portion  73  and the vacuum hair collection canister  00  at the suction head portion  99  by a flexible rubber connector  62 ,  64  integrally contoured at its interior to fit snugly onto the handle butt portion  73  and engage there the suction hose central clip formation  83  such that the snug fit is substantially airtight where the mouth of the hose  66  attaches at the butt  73  of the clipper  70 . The connector  62  is externally shaped as a comfortable and esthetically appealing extension of the clipper handle  70  (best seen in FIG.  2 ). Said connector is shaped at its base to provide for utilitarian play of the suction hose  66  installed therein, which play naturally occurs while the clipper  70  is in operation and/or is mobile. 
     VACUUM CANISTER 
     Referring now to  FIGS. 14 and 28 , in the preferred embodiment present invention the vacuum hair collection canister  90  comprises storage capacity  96 ,  97 , a vacuum suction head portion  88  having suction hose connector means  64  and connector clip formations  65 , a vacuum motor house  101  having a motor  100  and switch  107 , and wiring  84 ,  91 ,  104  of means known in the art to be sufficient to power both the vacuum motor  100  and the clipper motor  80 . The vacuum hair collection canister  90  also includes a filtration means  93  ( FIG. 14 ) sufficient to collect clipped hair debris evacuated from the cutting portion of the blade assembly  40  through the clipper handle  70  and through the suction hose  88  into said canister  90 . 
     Referring still to  FIGS. 14 and 28  more specifically, wiring  84 ,  91 ,  104  of means known in the art preferably supplies power by way of a single electrical outlet initially to the vacuum motor  100  and then to the clipper motor  80  by continuing the electrical power supply  104  to the vacuum motor switch  107 , the vacuum motor  100 , the conventional power transfer means  91 ,  84  known in the art and the male and female connectors  108 ,  106 . From this point, the power supply travels preferably through the interior of the suction hose  66  toward connectors  85 ,  86  that supply the clipper motor  80  and switch  83  thus driving the blade assembly  40 . Also contemplated for use in the present invention is wiring of means known in the art to be sufficient to power both the vacuum motor  100  and the clipper motor  60  but not limited to a single electrical outlet and/or not limited to traveling through the interior of the suction hose  66 . 
     Referring now to  FIG. 28 , the vacuum hair collection canister  90  provides the user with a personal sized means for evacuating and collecting clipped hair debris from the skin surface and from the work area while using the clipper unit  70 . The vacuum canister  90  preferably is light-weight, provides quiet operation, and includes: storage means  98  for the clipper unit; storage means  97  for the suction hose  66 ; a built-in minor  98 ; varied length guard/gauges  113 ,  114 ,  115  and skin guard SG 1 ; and varied attachments or accessories including but not limited only to a back-reach attachment  112 , a cleaner brush  116  and blade lubricating oil  117 . Such attachments or accessories are contemplated to provide the user with, for example, a means to hold up a built-in mirror  98  housed within the light-weight hair collection canister  90  for viewing otherwise difficult-to-see body parts such as the back while utilizing the clipper unit with the attachments such as the back-reach attachment and a guard/gauge to trim hair on the back or on the neck and shoulders. Such a scenario inherently provides the user with added safety and comfort in that one hand is used to control the location of the canister unit  90  and one hand is used to control the location of the clipper unit  70  at all times, with the suction hose  66  remaining safely and not overextended there between. Thus, the canister unit need never be caused to fail, and the clipper unit need never be pulled out of control due to overextension of the suction hose. Therefore, the preferred light-weight portability and built-in mirror  98  of the canister unit  90  are integral to the preferred safest operation of the invention. 
     Referring now to  FIGS. 13 and 14 , the preferred method of attachment for the suction hose  66  to the canister suction head portion  99  is similar in design to the method described above for attachment to the clipper handle butt portion  73  in the section designated “Suction Hose.” Pertinent components for attachment of the suction hose  66  to the canister suction head portion  99  are the suction hose  66 , the flexible rubber connector  64 , the canister suction head portion  99 , the clip formation  66 , and the preferably female connector  106  having a mounting means  82  of neoprene or other material and having its corresponding male connector  105 . 
     Referring now to  FIG. 14 , this vacuum hair collection canister of the type suitable for use in the present invention is generally designated  90  and preferably is made of durable, impact-resistant molded polymeric or plastic material as is known in the art. The overall appearance of the preferred canister is rectangular and has the approximate dimensions of 9″ w×2.6″ h, when viewed laterally. The depth (not shown) of the canister is preferred to be approximately 4.35 inches providing ample space for a vacuum motor plus storage capacity as described above. Viewing  FIG. 14 , it is seen that the right lateral side denotes the base  102  of the vacuum motor house serving a means for securing the motor  100  into the motor housing  101  by way of screws  108  that are also contemplated as clips, tabs, or other fastening means. Said base is vented to allow for the escape of vacuum exhaust  109 . Additionally, in the present embodiment are provisions including but not limited only to a readily accessible filtration means  63 , compartment access  92  such that storage  06 ,  07  and suction hose connection  64 ,  65  and wiring connectors  105 ,  106  preferably are accessible to the user, as well as a built-in mirror  98 . 
     Referring now to  FIGS. 14 and 28 , preferably appearing on the top face of the canister, but wired internally, is a motor switch  107 . Said switch preferably provides several settings including: “on, ” “off,” “suction high,” “suction low,” “clipper with suction,” and “clipper without suction.” The variability in the preferred embodiment vacuum motor switch allows the user to power the invention under several scenarios including using the clipper unit with air suction or without, and including varying the air suction from high to low, and including turning on or off the invention at a single switch. More specifically, the clipper motor switch  83  preferably is wired to the vacuum motor switch  107  by means known in the art such that when the clipper motor switch is left in the “on” position the vacuum power supply switch functions to “turn it on” or “turn it off” from the canister location, rather than necessitating that both the clipper motor switch and the vacuum motor switch be independently switched to their “on” or “off” positions. Conversely, if the user prefers additional cautionary measures when operating the clipper unit, the clipper motor switch  83  can be left in the “off” position necessitating that it be independently “turned on” at the user&#39;s discretion in order to operate the clipper unit  70 . Additionally, the switch functions are describe as including variability in switch functions to power the vacuum and clipper switches and motors either separately or in combination with one another. 
     While a particular embodiment of the present invention pivotable blade hair clipper and suction collection system has been shown and described it will be appreciated by those skilled in the art that changes and modifications maybe made thereto without departing from the invention in its broader aspects and as set forth in the following claims.
