Tool to aid in fireplace flue installation

Abstract

The tool to aid in fireplace flue installation supports the sections of a flue during attachment to the vent of a fireplace or stove. The tool has a support bracket for mounting the tool to a vertical support, such as a stud in a chase where the flue will be installed. Attached to the support bracket is an arm support member, which holds a plurality of flue support arms. The flues support arms are pivotally attached to the support member so that the arms rotate about a vertical axis. Each support arm can be rotated independently of the other support arm or arms. The support arms are provided with setscrews, which are tightened to lock the support arms into a selected position. Each support arm may be provided with an arm extension, which slidably engages the support arm, allowing the overall length of the arm to be extended.

1 . A tool to aid in fireplace flue installation, comprising: 
 an elongated support bracket adapted for attachment to a wall stud adjacent a fireplace installation;    an elongated support rod attached to the support bracket;    at least one support arm pivotally mounted on the support rod, the support arm having a flue supporting member extending transverse to the support rod adapted for supporting a flue pipe; and    means for selectively locking the support arm with the flue supporting member at a desired angle of rotation about the support rod.    
   
   
       2 . The tool according to  claim 1 , wherein said support bracket has at least one keyhole slot defined therein adapted for hanging the support bracket on a nail driven into the wall stud.  
   
   
       3 . The tool according to  claim 1 , wherein the flue supporting member extends at an acute angle relative to the support rod, whereby the flue supporting member is adapted for sloping upward above the fireplace installation.  
   
   
       4 . The tool according to  claim 1 , wherein said flue supporting member comprises an extendable member including a base member and an extension member slidable within the base member in telescoping manner, the extension arm being extendable from the base member.  
   
   
       5 . The tool according to  claim 4 , wherein said at least one supporting arm further comprises a length adjustment screw extendable through the base member in order to releasably clamp the extension arm, thereby temporarily fixing the flue supporting member at a selectable length.  
   
   
       6 . The tool according to  claim 5 , wherein said at least one support arm comprises two support arms and a bearing disposed between the two support arms, whereby the support arms are independently rotatable about the support rod.  
   
   
       7 . The tool according to  claim 1  wherein the means for locking comprises a setscrew mounted in said support arm and selectively extendable to engage said support rod.  
   
   
       8 . The tool according to  claim 1 , further comprising a catch mounted on the flue supporting member and extending normal to the flue supporting member adapted for preventing the flue pipe from sliding off the flue support member.  
   
   
       9 . The tool according to  claim 8 , wherein said catch comprises a pin.  
   
   
       10 . The tool according to  claim 1 , wherein said flue supporting member comprises a base tube, said support arm having a support rod tube transverse to the base tube rotatably disposed on the support rod for pivoting said support arm.  
   
   
       11 . The tool according to  claim 10 , wherein said support arm further comprises a gusset plate extending between the support rod tube and the base tube.  
   
   
       12 . A tool to aid in fireplace flue installation, comprising: 
 an elongated support bracket adapted for attachment to a wall stud adjacent a fireplace installation in a vertical orientation;    an elongated support rod attached to the support bracket and extending parallel to the support bracket;    a first support arm and a second support arm, each of the support arms having a vertically oriented tube rotatably disposed on the support rod and a tubular arm extending substantially normal to the vertically oriented tube, the tubular arm being adapted for supporting a flue pipe, the vertically oriented tubes of the first and second arms being sequentially stacked on the support rod, the tubular arms having different lengths;    a bearing disposed on the support rod between the first and second support rods; and    first and second setscews selectively extendable through the vertical tubes of the first and second support arms, respectively, for selectively clamping the support arm to the support rod;    whereby the first and second support arms are adapted for supporting inner and outer walls of a double wall flue pipe above the fireplace installation and independently rotatable for sequential installation of the inner and outer walls.    
   
   
       13 . The tool according to  claim 12 , wherein said tubular arm comprises a telescoping tubular arm and locking means for adjusting the telescoping arm at a selectable length.  
   
   
       14 . The tool according to  claim 12 , further comprising a pin extending normal from an end of the tubular arm of each of said support arms, the pin being adapted for retaining the flue pipe on said support arms.
