Bedspring frame machine

Claim 2

A bedspring frame Nailing machine for nailing together transverse and longitudinal marginal wooden members and wooden slat members comprising a longitudinal horizontal machine frame, a transverse horizontal anvil at about the midpoint of said machine frame, a transverse superstructure above said anvil of said machine frame, a carriage mounted for vertical reciprocation on said superstructure toward and away from said machine frame, a plurality of pneumatic nailing tools on said carriage positioned above said anvil, guide means on said machine frame for guiding said wooden members in predetermined aligned positions along said machine frame and beneath said nailing tools, power-actuated means for moving said wooden members in increments longitudinally through said machine, and power-actuated means for reciprocating said carriage on said superstructure, said guide means comprising at least one transverse horizontal shaft supported by said machine frame, and a plurality of carriers adjustably positioned along said shaft, each said carrier having a pin projecting above the path of movement of said slat members, pairs of carriers confining movement of said slat members transversely of said machine frame.

Claim 3

A machine according to claim 1, which further comprises mounting means mounting said nailing tools on said carriage comprising a first transverse member fixed to said carriage, means pivotally mounting said tools on said first transverse member, a second transverse member, power-actuated means for reciprocating said second member parallel to and spaced from said first member, and means connecting said tools to said second member, whereby upon movement of said second member in one direction at least some of said tools discharge nails in first positions and after movement of said second member in the opposite direction at least some of said tools discharge nails in second positions transversely spaced from said first positions.

Claim 4

A machine according to claim 1, in which said shaft is oscillatory between a first position with said pins projecting upward and a second position with said pins below said path of movement to permit passage of said transverse marginal members and resilient means biasing said shaft toward first position.

Claim 5

A machine according to claim 1, in which said guide means is formed with an opening at one side of said superstructure, a squeeze member horizontally reciprocable opposite said opening and cooperating means on said carriage and said squeeze member to move said squeeze member inward of said opening to clamp one said transverse marginal member relative to said longitudinal marginal members.

Claim 6

A bedspring frame nailing machine for nailing together transverse and longitudinal marginal wooden members and wooden slat members comprising a longitudinal horizontal machine frame, a transverse horizontal anvil at about the midpoint of said machine frame, a transverse superstructure above said anvil of said machine frame, a carriage mounted for vertical reciprocation on said superstructure toward and away from said machine frame, a plurality of pneumatic nailing tools on said carriage positioned above said anvil, guide means on said machine frame for guiding said wooden members in predetermined aligned positions along said machine frame and beneath said nailing tools, power-actuated means for moving said wooden members in increments longitudinally through said machine, power-actuated means for reciprocating said carriage on said superstructure, a permanent frame surrounding said wooden members and providing support therefor as said wooden members advance through said machine, cooperating first means on said permanent frame and second means on said machine frame for limiting sequential increments of movement of said permanent frame through said machine, timing means for reciprocating said second means in timed relation of reciprocation of said carriage, and second timing means for limiting movement of said permanent frame to lesser increments than the movement limited by saiD first-mentioned timing means.

Claim 7

A bedspring frame nailing machine for nailing together transverse and longitudinal marginal wooden members and wooden slat members comprising a longitudinal horizontal machine frame, a transverse horizontal anvil at about the midpoint of said machine frame, a transverse superstructure above said anvil of said machine frame, a carriage mounted for vertical reciprocation on said superstructure toward and away from said machine frame, a plurality of pneumatic nailing tools on said carriage positioned above said anvil, guide means on said machine frame for guiding said wooden members in predetermined aligned positions along said machine frame and beneath said nailing tools, power-actuated means for moving said wooden members in increments longitudinally through said machine, power-actuated means for reciprocating said carriage on said superstructure, a permanent frame surrounding said wooden members and providing support therefor as said wooden members advance through said machine, cooperating first means on said permanent frame and second means on said machine frame for limiting sequential increments of movement of said permanent frame through said machine, timing means for reciprocating said second means in timed relation of reciprocation of said carriage, and second timing means for limiting movement of said permanent frame to lesser increments than the movement limited by saiD first-mentioned timing means.

Claim 8

A bedspring frame nailing machine for nailing together transverse and longitudinal marginal wooden members and wooden slat members comprising a longitudinal horizontal machine frame, a transverse horizontal anvil at about the midpoint of said machine frame, a transverse superstructure above said anvil of said machine frame, a carriage mounted for vertical reciprocation on said superstructure toward and away from said machine frame, a plurality of pneumatic nailing tools on said carriage positioned above said anvil, guide means on said machine frame for guiding said wooden members in predetermined aligned positions along said machine frame and beneath said nailing tools, power-actuated means for moving said wooden members in increments longitudinally through said machine, power-actuated means for reciprocating said carriage on said superstructure, a permanent frame surrounding said wooden members and providing support therefor as said wooden members advance through said machine, a rack on said permanent frame, a transverse shaft in said machine frame having a pinion engaging said rack, and means for intermittently rotating said pinion in a direction to advance said permanent frame and a one-direction clutch in said shaft permitting retraction of said permanent frame.

Claim 9

A bedspring frame nailing machine for nailing together transverse and longitudinal marginal wooden members and wooden slat members comprising a longitudinal horizontal machine frame, a transverse horizontal anvil at about the midpoint of said machine frame, a transverse superstructure above said anvil of said machine frame, a carriage mounted for vertical reciprocation on said superstructure toward and away from said machine frame, a plurality of pneumatic nailing tools on said carriage positioned above said anvil, guide means on said machine frame for guiding said wooden members in predetermined aligned positions along said machine frame and beneath said nailing tools, power-actuated means for moving said wooden members in increments longitudinally through said machine, power-actuated means for reciprocating said carriage on said superstructure, a permanent frame surrounding said wooden members and providing support therefor as said wooden members advance through said machine, a rack on said permanent frame, a transverse shaft in said machine frame having a pinion engaging said rack, and means for intermittently rotating said pinion in a direction to advance said permanent frame and a one-direction clutch in said shaft permitting retraction of said permanent frame.
