Abstract:
This invention pertains to improvements in that class of metal-planing machines known as "openside" planers and involving a bed, work-holding devices at the side of the bed, a carriage reciprocating upon the top of the bed, a rigid arm carried by the carriage and projecting out over the work-holding devices, and tool holding appliances carried by and adjustable in and out upon the overhanging projecting arm. The accuracy of the work produced by this class of planers is dependent upon the accuracy of the sliding motion of the carriage upon the bed. Under working conditions a very peculiar set of strains are set up, the tendency of which in ordinary constructions is to interfere with accuracy of movement or the maintenance of accuracy.
Claim:
In a planing-machine, the combination, substantially as set forth, of a bed, work-holding devices at the side thereof, a carriage adapted to reciprocate along the top of the bed, an arm upon the carriage overhanging said work-holding devices, tool holding devices mounted on said arm, a longitudinal guideway disposed at the front upper portion of the bed and provided with upwardly and laterally presenting guiding-surfaces, a longitudinal guideway disposed at the rear upper portion of the bed and provided with an upwardly presenting surface, wings upon the front portion of said carriage engaging said front guideway of the bed, a rear portion of said carriage engaging the rear guiding-surface of the bed and having a bearing thereon longitudinally less in extent than the bearing at said wings, and mechanism for reciprocating the carriage upon the bed. |
