Title: Watering device with long shank

Description:
FIELD OF THE INVENTION  
      The present invention relates to a watering device having a long shank and two sets of dispensing members are respectively connected to two ends of the long shank so as to guide water to the sprinkler head.  
     BACKGROUND OF THE INVENTION  
      A conventional watering device is disclosed in  FIG. 8  and generally includes a head  7  with a long shank  8  connected thereto. The handle  10  has a first end connected to the shank  8  and a second end of the handle  10  is connected to a hose through which water is supplied to the shank  8 . A dispensing member  9  is connected to the first end of the handle  10  and a plurality of small hoses  6  are combined and connected to the dispensing member  9 . The small hoses  6  are inserted in the shank  8  and extend through the head  7 . Another dispensing member  5  is connected to the head  7  and includes three pattern holes which are in communication with the small hoses  6 . It is noted that the small hoses  6  have to be adhered with each other so as to be secured in the shank  8 . Due to the thickness of walls of the small tubes  6 , only limited number of the small tubes  6  can be inserted in the shank  8  and the thickness of the small hoses  6  limits the volume of water going through the shank  8 . It takes a lot of time to install the small hoses  6  in the shank  8  and the diameter of the small hoses  6  could be narrowed by the adhesive used for connecting the small hoses  6 .  
      The present invention intends to provide a watering device wherein no small hoses are needed and the watering device can be assembled within a short period of time.  
     SUMMARY OF THE INVENTION  
      The present invention relates to a watering device that comprises a head connected to a first end of a hollow shank which has a plurality of first ribs extending radially from an elongate core and connected to an inner periphery of the shank. An adjusting set is connected to a second end of the shank and includes an operation member. A through hole is defined in a close end of the operation member and an end member is connected to the other end of the operation member. The end member has a tube which has an opening defined through a wall thereof. A board is biased by the tube and includes a plurality of holes and one of the holes is in alignment with the through hole of the operation member. A dispensing member has a peripheral wall extending from a first side thereof and the peripheral wall is connected to the board opposite to the tube and a gap is defined between the board and the dispensing member. A plurality of tubes extend from a second side of the dispensing member and communicate with the gap between the board and the dispensing member. The tubes are engaged with the first ribs in the shank, a locking collar mounted to the second end of the shank and threadedly connected to the operation member.  
      The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      Referring to FIGS.  1  to  4  and  7 , the watering device of the present invention comprises a head  1  connected to a first end of a hollow shank  2  and an adjusting set is connected to a second end of the shank  2 . A water supply is connected to the adjusting set. The shank  2  has a plurality of first ribs  21  extending radially from an elongate core and connected to an inner periphery of the shank  2 .  
      The adjusting set includes an operation member  3  having a through hole  32  defined in a close end  33  thereof and an end member  4  is connected to the other end of the operation member  3  with a seal  40  sealing the operation member  3 . The end member  4  has a tube  41  which has an opening  411  defined through a wall thereof and is inserted in the interior space  31  of the operation member  3 . A board  35  is biased by the tube  41  and includes a plurality of holes  351  which may have different sizes, and one of the holes  351  is in alignment with the through hole  32  of the operation member  3 . A seal  34  is engaged with a sink recess enclosing the through hole  32  to prevent from leakage. A dispensing member  36  has a peripheral wall extending from a first side thereof and the peripheral wall is connected to the board  35  opposite to the side contacting the tube  41 , and a gap  361  is defined between the board  35  and the dispensing member  36 . A plurality of tubes  133  extend from a second side of the dispensing member  36  and communicate with the gap  361  between the board  35  and the dispensing member  36 . The tubes  133  are engaged with the first ribs  21  in the shank  2 . A locking collar  37  is mounted to the second end of the shank  2  with a seal  39  engaged therebetween and threadedly connected to a threaded portion  42  on the operation member  3 . A receiving member  38  has a tubular section  381  and a flange  382  extends radially from the tubular section  381 . The tubular section  381  extends through the locking collar  37  and the second end of the shank  2  inserted in the tubular section  381 . An inside of the locking collar  37  contacts the flange  382 . Water enters the interior space  31  of the operation member  3  via the opening  411  and flows through the hole  351  and enters the gap  361 . The water then enters the shank  2  via the through holes  362  of the dispensing member  36 . By rotating the operation member  3  and checking the index  321  marked thereon via a window defined in the locking collar  37  may adjust the desired the hole  351  in the board  35  to be in alignment with the through hole  32  of the operation member  3 , such that the water can be used in a desired way.  
      Referring to  FIGS. 5 and 6 , the head  1  includes a connection member  13  having a hole defined centrally therethrough and a plurality of tubes  133  extend from a first side thereof. Gaps are defined between the tubes  133  which are in communication with the hole in the connection member  13 . The first ribs  21  in the shank  2  are engaged with the gaps between the tubes  133 . A plurality of second ribs  132  extend from a second side of the connection member  13 . A guide member  12  has a plurality of stream paths  122  defined therein and a threaded neck extends from an end of the guide member  12 . The threaded neck includes a plurality of chambers  121  separated by ribs  121  received therein and the second ribs  132  of the connection member  13  are engaged with the chambers  121 . A pattern member  11  is connected to an end opposite to the end having the threaded neck and has a plurality of pattern holes  111  which are in communication with the stream paths  122  in the guide member  12 . A locking collar  15  has threaded inner periphery  151  and is mounted to the first end of the shank  2 . The threaded inner periphery  151  is connected to the threaded neck of the guide member  12 . A receiving member  14  has a tubular section  141  and a flange  142  extends radially from the tubular section  141 . The first end of the shank  2  inserted in the tubular section  141  which extends through the locking collar  15  and an inside of the locking collar  15  contacts the flange  142 .  
      While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
