  patented

  package 
  for

  &c. 
  See

  The 
  invention 
  relates 
  to 
  the 
  construction 
  of 
  the 
  removable 
  head 
  of 
  

   barrels, 
  tubs, 
  or 
  other 
  vessels 
  in 
  which 
  oysters 
  and 
  other 
  similar 
  perish- 
  

   able 
  articles 
  are 
  packed, 
  and 
  has 
  for 
  its 
  object 
  so 
  to 
  construct 
  the 
  re- 
  

   movable 
  head 
  that 
  it 
  can 
  be 
  readily 
  applied 
  and 
  removed, 
  and 
  that 
  wben 
  

   applied 
  it 
  is 
  sufficiently 
  tight 
  to 
  prevent 
  the 
  escape 
  of 
  the 
  contents 
  of 
  

   the 
  package, 
  and 
  that 
  it 
  can 
  be 
  readily 
  sealed, 
  and 
  tbat 
  it 
  has 
  no 
  pro- 
  

   jecting 
  parts 
  which 
  would 
  interfere 
  with 
  the 
  handling 
  and 
  stowing 
  of 
  

   the 
  package 
  in 
  transportation. 
  At 
  the 
  upper 
  head 
  are 
  two 
  segmental 
  

   side 
  pieces. 
  These 
  are 
  fixed 
  within 
  the 
  barrel 
  upon 
  an 
  inner 
  hoop, 
  

   there 
  being 
  a 
  groove 
  on 
  the 
  curved 
  edge 
  of 
  each 
  piece 
  which 
  fits 
  upon 
  

   the 
  hoop, 
  and 
  nails 
  being 
  driven 
  from 
  the 
  exterior 
  of 
  the 
  barrel 
  through 
  

   the 
  hoop 
  into 
  the 
  side 
  pieces. 
  Between 
  the 
  parallel 
  sides 
  of 
  the 
  side 
  

   pieces 
  is 
  the 
  removable 
  portion 
  of 
  the 
  head, 
  which 
  consists 
  of 
  two 
  parts 
  

   hinged 
  together 
  below. 
  The 
  outer 
  ends 
  are 
  grooved 
  to 
  fit 
  over 
  the 
  rest 
  

   of 
  the 
  hoop. 
  Each 
  removable 
  part 
  has 
  at 
  its 
  side 
  a 
  packed 
  offset 
  which 
  

   rests 
  upon 
  an 
  offset 
  on 
  the 
  corresponding 
  side 
  piece. 
  Two 
  clamps 
  piv- 
  

   oted 
  to 
  the 
  side 
  pieces 
  opposite 
  the 
  hinged 
  edges 
  of 
  the 
  removable 
  por- 
  

   tion 
  overlap 
  the 
  adjacent 
  parts 
  and 
  secure 
  them 
  in 
  place. 
  Each 
  clamp 
  

   consists 
  of 
  two 
  wings, 
  respectively, 
  on 
  the 
  upper 
  and 
  lower 
  sides 
  of 
  the 
  

   cover, 
  and 
  secured 
  to 
  the 
  same 
  by 
  a 
  vertical 
  pivot 
  which 
  turns 
  in 
  the 
  

   side 
  piece. 
  The 
  upper 
  wing 
  has 
  an 
  arm 
  which 
  projects 
  rearward, 
  and 
  

   turns 
  upon 
  a 
  plate 
  secured 
  to 
  the 
  top 
  of 
  the 
  side 
  piece. 
  The 
  plate 
  has 
  

   two 
  upward-projecting 
  stops 
  to 
  limit 
  the 
  movement 
  of 
  the 
  arm 
  to 
  a 
  

   quarter-circle. 
  One 
  of 
  the 
  stoics 
  and 
  the 
  arm 
  resting 
  upon 
  it 
  is 
  perfo- 
  

   rated, 
  so 
  that 
  the 
  wire 
  of 
  a 
  seal 
  may 
  be 
  drawn 
  through 
  both 
  perforations, 
  

   thereby 
  preventing 
  the 
  clamp 
  from 
  being 
  turned 
  without 
  breaking 
  the 
  

   seal. 
  The 
  upper 
  wing 
  and 
  the 
  arm 
  are 
  in 
  one 
  piece 
  with 
  a 
  hub, 
  the 
  

   exterior 
  surface 
  of 
  which 
  is 
  hexagonal, 
  turned 
  by 
  a 
  wrench. 
  One 
  of 
  the 
  

   removable 
  parts 
  is 
  provided 
  with 
  a 
  removable 
  handle 
  shaped 
  to 
  serve, 
  

   when 
  removed, 
  as 
  a 
  wrench 
  to 
  turn 
  the 
  clamps. 
  The 
  wrench 
  end 
  of 
  

   the 
  handle 
  is 
  attached 
  to 
  the 
  cover 
  by 
  a 
  metallic 
  strap, 
  which 
  is 
  secured 
  

   to 
  the 
  upper 
  side 
  of 
  the 
  cover, 
  leaving 
  sufficient 
  space 
  between 
  the 
  un- 
  

   der 
  side 
  and 
  the 
  upper 
  side 
  of 
  the 
  cover 
  to 
  permit 
  this 
  end 
  of 
  the 
  han- 
  

   dle 
  to 
  be 
  inserted 
  under 
  the 
  strap. 
  The 
  cover 
  is 
  provided 
  with 
  depres-
