  Disappearing  \Dis`ap*pear"ing\, 
  p.  pr  &  vb  n.  of  {Disappear}. 
 
  {Disappearing  carriage}  (Ordnance),  a  carriage  for  heavy 
  coast  guns  on  which  the  gun  is  raised  above  the  parapet 
  for  firing  and  upon  discharge  is  lowered  behind  the 
  parapet  for  protection.  The  standard  type  of  disappearing 
  carriage  in  the  coast  artillery  of  the  United  States  army 
  is  the  {Buffington-Crozier  carriage},  in  which  the  gun 
  trunnions  are  secured  at  the  upper  and  after  ends  of  a 
  pair  of  heavy  levers,  at  the  lower  ends  of  which  is 
  attached  a  counterweight  of  lead.  The  levers  are  pivoted 
  at  their  middle  points,  which  are  with  the  top  carriage, 
  permitted  restrained  motion  along  the  slightly  inclined 
  chassis  rails.  The  counterweight  is  held  in  place  by  a 
  pawl  and  ratchet.  When  the  gun  is  loaded  the  pawl  is 
  released  and  the  counterweight  sinks,  raising  the  gun  to 
  the  firing  position  above  the  parapet.  The  recoil 
  following  the  discharge  returns  the  gun  to  the  loading 
  position,  the  counterweight  rising  until  the  pawl  engages 
  the  ratchet.
