  of 
  the 
  barrel 
  is 
  fixed. 
  Upon 
  the 
  inside 
  of 
  this 
  head 
  

   is 
  a 
  rim 
  which 
  forms 
  a 
  recess 
  in 
  which 
  rests 
  the 
  bottom 
  of 
  a 
  can, 
  the 
  

   can 
  being 
  stayed 
  at 
  the 
  top 
  by 
  a 
  ring

  head 
  of 
  the 
  barrel 
  bears 
  upon 
  the 
  upper 
  end 
  "of 
  the 
  can 
  

   and

  in 
  recesses 
  

   on 
  the 
  inner 
  side 
  of 
  the

  extends 
  outward 
  through 
  an 
  opening 
  in 
  the 
  head. 
  On 
  one 
  

   end 
  of 
  the 
  lever 
  to 
  which 
  the 
  bolts 
  are 
  attached 
  is 
  a 
  disk 
  nearly 
  circular, 
  

   and 
  the 
  bolts 
  are 
  so

  outer 
  end 
  of 
  the 
  lever 
  in

  the 
  casing 
  being 
  provided 
  with 
  openings 
  through 
  

   which 
  the 
  sliding 
  bolts 
  protrude. 
  One 
  sliding

  is 
  provided 
  with 
  an 
  upward 
  projecting 
  tongue, 
  and 
  the 
  

   lever 
  has 
  an 
  opening 
  which 
  permits 
  the 
  tongue 
  to 
  project 
  through 
  it,
