able) ;  that  it  may  be  so  constructed  that  it  may  be  made  of  any 
dimensions  to  fit  the  space  available ;  and  that  it  may  be  enlarged 
or  diminished  in  size,  to  suit  the  needs  of  the  business. 
The  stand  which  is  here  described  is  the  result  of  an  effort  to 
supply  all  these  requirements.  It  is  constructed  of  two  upright 
tubes  of  heavy  iron,  secured  firmly  at  the  bottom  by  counter  plates. 
Two  parallel,  horizontal,  double  tubes  are  arranged  so  as  to  slide 
up  and  down  these  upright  tubes,  and  made  secure  by  means  of 
thumbscrews  at  each  end.  This  completes  the  framework  of  the 
stand.  The  ring  clamps,  instead  of  being  all  in  one  piece,  as  in  the 
ordinary  stands,  are  made  in  two  parts,  the  clamp  composing  one 
part,  and  the  rings,  with  1 2-inch  shanks,  the  other  part.  The 
shanks  of  the  rings  are  passed  through  two  openings  in  the  clamps, 
and  are  made  secure  by  thumbscrews.  The  clamps  are  of  two 
kinds,  those  which  slide  horizontally  on  the  double  tubes,  and  those 
which  slide  vertically  on  the  upright  tubes.  The  shafts  of  the 
rings  are  all  of  the  same  size,  so  that  they  can  be  used  with  either 
form  of  clamp,  the  rings  varying  in  diameter  from  3  inches  to 
7  inches. 
All  the  thumbscrews  are  of  brass,  so  as  to  prevent  the  possi- 
bility of  rusting,  and  the  castings  are  of  malleable  iron,  so  that  the 
chance  of  breakage  is  very  slight.  The  framework,  being  all 
composed  of  heavy  iron  tubing,  is  sufficiently  strong  and  firm  to 
uphold  any  weight  which  would  be  likely  to  be  put  upon  it,  and 
every  part  is  constructed  with  a  view  to  withstand  hard  usage. 
It  will  be  readily  seen  that  the  adjustability  of  this  apparatus 
stand  is  complete.  It  is  possible  to  get  any  desired  position  of  the 
rings  in  the  three  dimensions  of  space,  upward  or  downward,  right 
or  left,  backward  or  forward. 
The  space  which  it  occupies  when  not  in  use  and  the  rings  re- 
moved is  very  small.  The  frame  stands  on  the  counter  4  inches 
from  the  wall,  thus  taking  up  the  room  which  is  least  valuable,  and 
leaving  all  the  front  part  of  the  counter  available  for  other  pur- 
poses. As  the  amount  of  space  varies  considerably  in  different 
stores,  the  advantage  which  this  stand  possesses  in  being  made  of 
iron  tubing  which  can  be  cut  in  any  length  to  suit  the  space  avail- 
able, and  the  fact  that  it  can  be  screwed  to  the  counter  or  to  the 
wall,  or  suspended  from  a  shelf  or  the  ceiling,  will  commend  it  to 
the  practical  and  busy  pharmacist.
