     DETAILED DESCRIPTION 
       FIG. 1  shows an isometric perspective of a portable concrete vibrator system  10 . The concrete vibrator system  10  is used primarily to consolidate fresh concrete so that entrapped air and excess water are released and the concrete settles firmly in place in the forms. Improper consolidation of concrete can cause product defects, compromise the concrete strength, and produce surface blemishes. 
     With continued reference to  FIG. 1 , the portable concrete vibrator system  10  includes a primary power source  20 . There are many varieties of the primary power source  20  such as, for example, an electric motor, a hydraulic motor, a pneumatic motor, a two-stroke engine, and as illustrated, a four-stroke engine. When configured with a four-stroke engine, the engine is typically in the range of 25 cc to 50 cc in displacement which net a couple of horsepower. In one particular embodiment, a Honda® Power Equipment Corp. 25 cc mini four-stroke OHC engine model GX35 has proven to be an acceptable primary power source  20 . This particular engine has a net horsepower output of 1.3 at 7,000 revolutions per minute (RPM). An additional specification of the GX35 is that it produces a net torque of 1.2 lbs-ft at 5,500 RPM. Therefore, the engine must be operated at a high rotation speed so that the torque is high enough to cause proper consolidation of the fresh concrete. 
     The portable concrete vibrator  10  is also provided with an inline transmission  100  that is the essence of the present application and will be described in greater detail later herein. This inline transmission  100  is physically attached to the primary power source to receive power generated by the primary power source  20 . The portable concrete vibrator system  10  is also provided with an elongated tubular member  22  defining a first distal end  24  and an opposite second distal end  26 . The elongated tubular member  22  is provided with a trigger handle  28  and a support handle  30  attached to the first and second distal ends  24 ,  26 , respectively. The elongated tubular member first distal end  24  is physically attached to the inline transmission  100 . Additionally, the elongated tubular member  22  is provided with a rigid driveshaft (not shown) located in the inside thereof. This rigid driveshaft is capable of receiving the power generated by the primary source via the inline transmission  100 . The power that is received by the rigid driveshaft is transferred from the elongated tubular member first distal end  24  to the second distal end  26 . 
     With continued reference to  FIG. 1 , the portable concrete vibrator  100  is also provided with a flexible tubular member  40  defining a first distal end  42  and an oppositely disposed second distal end  44 . The flexible tubular member  40  in an assembly of a variety of components such as, but not limited to, a flexible sheath  46  housing a flexible driveshaft (not shown) located inside thereof. 
     One of the key components of the concrete vibrator system  10  is a remote finishing tool  50 . There are many types of remote finishing tools such as a pendulous vibrator  52  illustrated in  FIGS. 1 ,  2  and  3  and a flexible shaft vibrator  54  illustrated in  FIGS. 4 and 5 . Although many types of these finishing tools are commercially available, various configurations of the pendulous vibrator  52  are described in U.S. Pat. No. 6,065,859 titled PORTABLE PENDULOUS CONCRETE VIBRATOR issued to Kenny D. Breeding on May 23, 2000 are specifically identified as a style of remote finishing tool well suited for the present invention. Therefore, U.S. Pat. No. 6,065,859 issued to Kenny D. Breeding on May 23, 2000 is specifically incorporated by reference for all that is disclosed therein. In general, the remote finishing tool  50  is immersed in wet concrete and used to release any entrapped air and excess water in a manner well-known in the industry. The remote finishing tool  50  is attached to the flexible tubular member  40  such that it receives the power generate by the primary power source  20  via the elongated tubular member  22  and the flexible tubular member  40 . This power is used to create a vibration which allows the power to be transferred to the concrete in which the remote finishing tool  50  is placed.

Once the assembly of the base  110 , the input assembly  250  and the first, second and third branch assemblies  360 ,  370 ,  380  as illustrated in  FIG. 15  occurs, the gasket  480  is placed into contact with the second end  114  of the base  110  and the locating pins  482 ,  484 ,  486  are put into the locator pin holes  168 ,  170 ,  172  ( FIG. 8 ). The next assembly step is to attach the cap  180 , the output assembly  400  and the release mechanism  460  as illustrated in  FIG. 17  to the base  110 . In attaching the cap  180 , the locator pin holes  208 ,  210 ,  212  ( FIG. 9 ) in the cap  180  are interfaced with the locating pins  482 ,  484 ,  486 . As a final assembly step, the bolts  488 ,  490 ,  492 ,  494  are positioned in the through holes  200 ,  202 ,  204 ,  206  ( FIG. 9 ) formed in the cap and ultimately threaded into the threaded holes  160 ,  162 ,  164 ,  166  ( FIG. 8 ). Having attached the components of the inline transmission  100 , it can be attached to the primary power source  20  as illustrated in  FIG. 20 . With reference to  FIG. 20  showing an isometric perspective of a primary power source  20  with an inline transmission  100  attached thereto, the base first end  112  of the inline transmission  100  is placed into contact with corresponding features formed in the primary power source  20 . In placing the inline transmission  100  against the primary power source  20 , the mounting holes  120  ( FIG. 6 ),  122  ( FIG. 7 ),  124  ( FIG. 6 ),  126  ( FIG. 6 ) of the base  110  are aligned to and ultimately utilized by bolts (not shown) to treadingly attach the inline transmission  100  to the primary power source  20 . After attaching the inline transmission  100  to the primary power source  20 , the various components of the concrete vibrator  10  illustrated in  FIG. 1  are attached to the inline transmission  100 . 
     Having described components, subassemblies and final assembly of one exemplary embodiment of the present inline transmission  100  for the concrete vibrator  10 , the method of using the same will now be provided. With reference to  FIG. 1  showing an isometric perspective of the portable concrete vibrator system  10 , the user pulls on a starter rope with a handle to start the primary power source  20 . Once the primary power source  20  is started and running, the remote finishing tool  50  is placed into fresh concrete and the user operates the trigger handle  28  to cause the primary power source  20  to generate power in the form of rotary energy. This rotary energy is transferred to the remote finishing tool  50  via the inline transmission  100 , the elongated tubular member  22  and the flexible tubular member  40 . As the remote finishing tool  50  operates in the mariner for which it is intended, it vibrates and transfers the energy to the concrete causing entrapped air and excess water are released from the concrete. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the concrete vibrator inline transmission, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the concrete vibrator inline transmission. 
     Directional terms such as “front”, “back”, “top”, “bottom”, “left”, “right”, “interior”, and the like may have been used in the description. These terms are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely used for the purpose of description in connection with the drawings and do not necessarily apply to the position in which the concrete vibrator inline transmission may be used. 
     Therefore, the foregoing is considered as illustrative only of the principles of the concrete vibrator inline transmission. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the concrete vibrator inline transmission to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the concrete vibrator inline transmission.
