and  a  half  inches  wide,  one  inch  thick  ;  a  slot  half  inch  wide  is  cut 
in  the  same  manner  in  them,  but  it  does  not  extend  the  whole  length, 
leaving  one  and  a  half  inch  solid  at  the  ends.  These  cross  pieces 
should  be  in  pairs,  and  seven  or  eight  pairs  should  be  made,  varying 
the  curves,  in  order  to  better  accommodate  the  various  shaped  perco- 
lators, funnels,  etc.,  which  may  be  used  ;  the  sides  of  the  curved  cross 
strips  should  be  beveled,  for  the  same  reason.  Iron  carriage  bolts, 
f  in.,  three  inches  long,  with  the  nut  replaced  by  thumb-screws,  are 
used  for  fastening  the  horizontal  long  strips  to  the  brackets,  and  also  the 
cross  pieces  to  the  horizontal  strips  ;  iron  washers  should  be  used  with 
the  thumb-screws  to  prevent  injury  to  the  wood. 
It  will  be  seen  that  by  this  contrivance  the  horizontal  strips  may  be 
made  to  approach  each  other  (by  inches,  if  desired)  by  slipping  out  the 
bolts  and  inserting  them  into  the  different  holes  in  the  bracket,  and  the 
cross  pieces  may  be  slipped  along  the  length  of  the  horizontal  strips  at 
will  or  when  they  are  needed  to  grasp  the  percolator  moved  to  their 
pro  er  position,  and  the  percolator  pushed  up  or  down  and  adjusted  to 
the  proper  height  to  suit  the  receiving  bottle,  and  the  thumb-screws 
can  then  be  used  to  secure  it,  so  that  a  solid,  vice  like  grasp  prevents 
the  percolator  from  tilting  or  getting  out  of  position. 
Funnels  for  filtration  can  of  course  be  readily  accommodated  by  the 
stand.  If  a  large  percolator  is  used,  the  top  may  be  run  up  to  what  is 
sometimes  called  the  "second  story,"  and  adjusted  by  the  cross  pieces 
in  the  upper  tier,  the  receiving  bottle  resting  on  the  counter.  Smaller 
operations  could  be  carried  on  on  the  first  floor,  but  if  there  is  no  more 
room  here,  and  it  is  required  to  construct  more  processes  on  a  smaller 
scale,  cross  pieces  may  be  laid  on  the  "first  floor"  horizontal  strips 
and  there  secured,  to  rest  the  receiving  bottle  on.  In  fact,  the  plan 
may  be  greatly  enlarged  and  is  susceptible  of  indefinite  multiplication, 
and  if  wall  space  can  be  spared  a  third,  fourth  and  fifth  floor,  or  tier, 
may  be  added. 
The  advantages  of  the  stand  are  that  many  operations,  which  would 
ordinarily  be  scattered  about  the  working  counter  or  carried  on  in  dif- 
ferent parts  of  the  store,  may  all  be  performed  in  a  very  limited  space 
and  hence  can  be  watched  and  attended  to  more  thoroughly.  The 
percolators  or  funnels  may  be  adjusted  to  a  nicety,  so  that  the  beaks 
may  extend  into  the  receiving  bottles  just  as  far  as  desired,  and  when 
these  are  full,  or  require  transferring,  it  is  easily  done.
