Description:

Three-quarter view of a double surfacing planer supported by six stout cast-iron legs. A spoked drive wheel is visible on the near side, connected to the mechanism enclosed within the central frame. A roller assembly sits above the planer bed, which extends toward the right. The following details are provided by the catalogue description:

[This machine] is intended  for  large  planing  mills,  bridge,  railroad  and  car  shops,  and  wherever a  heavy  and  substantial  machine  of  large  capacity  is  desired [...]

The  cylinders  are  belted  on  both  sides,  have  three  knives,  steel  lipped  chip  breakers and  wearing  edges,  large  steel  journals  with  long  and  self-oiling  bearings  all  perfectly  balanced. The  line  of  the  bed  being  in  a  fixed  position,  the  upper  cylinder  is  made  to adjust  to  the  thickness  of  the  lumber.

...The  upper  cylinder is  carried  in  stands,  planed  in  and  gibbed  to  the  sides  of  the  machine,  and  is  raised  and lowered  by  screws,  connected  by  gearing  worked  by  a  hand  wheel.  The  pressure  rolls are  raised  and  lowered  with  the  cylinder,  and  supplied  with  our  patent  folding  and weighted  levers,  allowing  the  rolls  to  operate  independently  or  together,  to  accommodate the  thickness  of  the  lumber.

The  under  cylinder  carries  three  cutters,  has  combined  boxes,  secured  to  a  heavy  yoke, which  can  be  instantly  raised  or  lowered  to  suit  the  work,  by  simply  turning  a  crank,  and is  made  easy  of  access  by  swinging  the  table  in  front  entirely  out  of  the  way  by  the removal  of  one  bolt,  both  upper  and  lower  pressure  bars  having  independent  adjustment.
