     FIELD OF THE INVENTION 
       [0002]    This application relates generally to pipe installation fixtures for buildings. 
       BACKGROUND OF THE INVENTION 
       [0003]    This invention provides an article and an installation method to insure that the proper pitch is employed in piping systems for the transport of liquids, typically constructed from plastic formulated pipes, such as a polyvinylchloride (PVC) and used in homes, offices and other facilities, generally. Although potable water and waste water, are the most frequent substance transported other fluids such as natural gas and gasoline are transported from one location to another via complex networks of pipes. These networks of pipes typically include long, relatively straight lines that enter into and exit from enclosed spaces, with occasionally intersected branches, and that may additionally bend around various enclosure walls and support structures, making it difficult to maintain a decreasing elevation as the piping progresses over its intended route. One problem with the use of piping systems is to insure that the pitch is in the direction of the sink and away from the source to insure the proper rate of flow and that liquid does not stagnate or worse, have impeded flow because pipes are pitched in the wrong direction. Presently there does not exist any device that insures a fool-proof means to install piping, especially in a rapid production fashion, that guarantees that the piping system is pitched properly, can be installed properly by a relatively unskilled work-force and is virtually no more expensive than the product without such advantages. With the foregoing in mind, the present invention will be distinguished over the prior art in the description and application of new components, design criteria and utility to the field of the invention. 
       SUMMARY OF THE INVENTION 
       [0004]    This invention provides a novel apparatus in for retaining a piping system in fixed but pitched association with a mounting surface. It is used for constructing a piping system including a least one stanchion, said stanchion having affixed thereto a universal pipe mount, vertically adjustable on the stanchion, for fixing a dimension from the pipe holder to a stanchion mounting surface. The apparatus may include two or more ganged or stacked stanchions and associated pipe holders that are used to insert the pipe, the distance between the pipe holders and the mounting surface designed to create a pitch of the pipe in the direction of the sink and away from the source of a liquid to insure the proper rate of gravitational flow. 
         [0005]    In another embodiment the disclosure is drawn to an apparatus for a piping system including: a first stanchion, having a dovetail at the head, and a second stanchion having an associated dovetail receiving slot at the foot, said dovetail and receiving slot cooperating for mating said first and second stanchions, and whereby at least one stanchion is fixed to a pipe holder for establishing a distance from the pipe holder to the mounting surface, creating a pitch of the pipeline in the direction of the sink and away from the source of a liquid to insure the proper rate of gravitational flow. 
         [0006]    In yet another embodiment the apparatus for a piping system includes: a first stanchion having movably secured thereto a universal fixture that employs a dovetail slot on each side to permit mounting a pipe holder having a dovetail. The apparatus further includes a boss with an eyelet which contains a through hole to permit threading a string line from the stanchion, for vertical adjustment according to a position relative to a pitch line, such as a sloped roof.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0016]      FIG. 1  shows a perspective view of the pipe pitch apparatus  100  in accordance with embodiments of the present invention and as previously substantially disclosed in the cross-referenced applications, Ser. No. 13/328,293 and Ser. No. 13/185,686. Stanchion  101  is used as the mounting device for a pipe holder  114  accessory to hold by way of example and not limitation a common pipe for transporting liquids. The pipe holder  114  is secured to the stanchion  101  via a universal adapter  104  having a tab  105  that cooperate to affixes to the face of the stanchion. One or more mounting feet, such as foot  108  secures the stanchion to a plane surface, such as a floor, ceiling or wall, utilizing by way of example and not limitation, an adhesive or a fastener, such as a nail or screw. A pipe recess  103  secures a pipe in the grip of a holder  114  that encompasses an angle of greater than 180 degrees, once inserted into the opening. The wide opening  103  is shown as a three-quarter open claim (approximately 270 degrees). In other applications an open configuration, such as a “U” shaped clamp of having an opening of 180 degrees or less, by way of example and not limitation, may be employed for applications such as heating-ventilation-air-conditioning (“HVAC”) line sets, cables, phone lines etc, where the transmission device is held secure according to the requirements of the installation specification. The “U” shaped clamp configuration or the greater than 180 degree holder  114  may typically be used in applications to lift the held item above a surface such as a roof top, while roofing installers/applicators spray urethane or apply weatherproofing compounds, roof insulation or foam panels to roof substrates and ultimately the top coat of rubber roof sealant. 
         [0017]      FIG. 2  illustrates a number of attachments or accessories that may be fitted to the stanchion  101  to hold various construction items, such as pipes, wires and other fixtures. In embodiments of the present disclosure,  FIG. 2  show a gas fired furnace pipe holder  130 , and the pipe holder  114 , all manufactured in various sizes having differing internal radii “r” sized to accommodate various sized pipes. Additionally the stanchion  101  may itself mount on a 90 degree bracket  119 , where the bracket is then permanently mounted on a vertical surface, such as a bulkhead, wall or vertical beam, such as a construction stud. 
         [0018]      FIG. 2  illustrates that each of the accessories has a mounting feature that allows affixation to the stanchion  101 . By way of example, a wire holder  112  and the pipe holder  114  has an associated dove tail  117  that slips into an accommodating guide-way, recess or slot  118  found on each side of universal mount  104 . Mount  104  then is securely affixed to the stanchion  101  utilizing the tab  105  and the guide  127 , which applies a lateral tension to the internal sides of beams  111   a  and  111   c , as further disclosed in the cross-referenced applications. Briefly, the tab  105  secures member  127  by gripping the front surface of the stanchion  101  beams  111   a  and  111   c , respectively, to retain the mount  104  fixed along the horizontal cross-section of the stanchion  101 . Similarly, mount  104   a  integral to gas furnace pipe holder  130  utilizes tabs  105  to secure members  127  by gripping the front surface of beams  111   a  and  111   c , respectively, to retain the mount  104   a  fixed along the horizontal cross-section of the stanchion  101 . And, again, similarly, wire holder  112  has a dove tail  116  that slips into the slid-way slot  118  on the mount  104  that then affixes to the stanchion  101 . The stanchion may hold multiple items, such as by example and not limitation,  112 ,  114 , and  130  simultaneously. 
         [0019]    With reference to  FIG. 2  and  FIG. 3 , a second stanchion  101  can be ganged or extended by utilizing the dovetail  125  in combination with a first stanchion  101  having a dove tail receiving slot  120   b  or a 90 degree bracket  119  having a dove tail receiving slot  107  in accordance with one embodiment of the present invention. With further reference to  FIG. 2  and  FIG. 3 , a stop  121  slips into stanchion  101  receiving slot  109 , as dovetails  120   a  slip into receiving slots  120   b  ( FIG. 2 ), such that the bracket assemble  119  and the stanchion cooperate in supporting the stanchion in three axial directions. For further support, the bracket  119  permits the stanchion  101  to be affixed to a vertical wall or stud surface via side member  220  and fastener slots  218  to a vertical support member, such as a wall stud or wall surface. 
         [0020]      FIG. 4  illustrates a master universal clamp  104  that employs dovetail guide-ways  118 , one per side, to permit the mounting of any compatible holder, such as the pipe holder  114  described in  FIG. 1 , allowing the system  100  to be used modularly. Any accessory clamps whether for electrical wire, large or small diameter pipes etc., can quickly be interchanged/used with universal clamp  104 . 
         [0021]      FIG. 5  illustrates a perspective view of a gas furnace pipe holder  130  for pipe pitch applications in accordance with one embodiment of the present invention. The opening secures the pipe under the tension from fingers  145 . The pipe holder  130  mounts onto the stanchion  101 , through the incorporation of adapter  104   a , shown in position for mounting in  FIG. 2 . A difference between adapter  104  as shown in  FIG. 5  and adapter  104   a  in  FIG. 4  is that the latter is a universal adapter that allows pipe holders and wire holders of varying types to mount on the stanchion  101  using a dovetail  117 , whereas the former adapter  104   a  is integral to the pipe holder  130 . 
         [0022]    It is difficult and time consuming for roofer/applicators to obtain the proper pitch to drains on flat roof when using sprayed foam insulation.  FIG. 6  illustrates a perspective view of a pipe pitch setting mechanism  142  in accordance with one embodiment of the present invention that is positioned on the backside and integral to the universal mount  104 , and used for setting a proper pitch. The pitch is established by sliding the universal adapter  104   a  vertically on the stanchion  101  according to the position relative to a pitch line  149 . The mount  104  has an eyelet comprised of boss  142  which contains a through-hole  143  to permit threading a string line  145 . The mount is adjusted to a reference pitch elevation angle θ in establishing the pitch of where the universal mount stanchion  101  should be fixed in place, in reference to a roof pitch line  149 . Once the applicator calculates the rise and run, he can set the toll at a proper height/elevation and easily follow the pitch of the string line to build up the roof pitch to ensure, by way of example and not limitation, that a proper drainage and pitch to roof top drains exists to prevent “ponding” and puddling on the roof. 
         [0023]      FIG. 7  illustrates a perspective view of a wire holder  112  apparatus in accordance with one embodiment of the present invention. Wire holder  112  has a dove tail  117  that slips into a guide-way slot  118  on the universal adapter mount  104  that then affixes to the stanchion  101 . The recess  155  which may be manufactured as multiple adapters allows wire and other types of utility devices to be held in place by preventing their slipping out of the recess by a protuberance  153 , which may also be formed from any material resistance or tab-like gate (not shown). 
         [0024]    With reference to  FIG. 6 , one embodiment of the invention herein also includes a method for pipe installation in a piping system including: mounting one or more pipes, each of said pipes in fixed association with mount  104 , said mount vertically adjustably associated with the stanchion  101  for establishing a pitch between the pipe relative to the mounting surface, utilizing reference pitch elevation angle θ formed by the pitched reference  149  and string line  145  attached to the mount  104  to set a vertical distance  151  between the mount and the pitched reference  149 . 
         [0025]    The apparatus  100  of the invention including its component parts, such as the stanchion  101  and universal adapter  104 , may be manufactured, by way of example and not limitation, from one of: any plastic, such as by way of example, Polyoxymethylene (Delrin, a registered trademark of E.I. du Pont de Nemours and Company) polyvinyl chloride PVC, chlorinated polyvinyl chloride CPVC, cast iron, or copper.
