Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
190 words
A horizontal milling machine comprising a horizontal frame member, a vertical face on said frame member having a recessed portion along its length substanTially complementary to a worktable to be received therein, a horizontal slide carried on said frame for movement in a horizontal direction, said slide supporting a tool carriage for movement in a vertical direction, a workpiece loading or unloading station at each longitudinal end of said machine, said frame member supporting a horizontally positioned pivot member extending substantially the entire length of the machine and adjacent the lower edge of said recessed portion, two worktables on which workpieces may be mounted, each said table being pivotable about and displaceable while in a vertical plane along said pivot member, separate drive means to effect the displacement and pivotal movement of the tables, means cooperating with said pivot member for retaining each of said worktables in a horizontal or a vertical position, whereby each said table may be securely supported at and moved between a substantially horizontal loading or unloading position at said station and a substantially vertical machining position in which it is received in said recessed portion.
Claim 2
Dependent Claim
190 words
A horizontal milling machine comprising a horizontal frame member, a vertical face on said frame member having a recessed portion along its length substanTially complementary to a worktable to be received therein, a horizontal slide carried on said frame for movement in a horizontal direction, said slide supporting a tool carriage for movement in a vertical direction, a workpiece loading or unloading station at each longitudinal end of said machine, said frame member supporting a horizontally positioned pivot member extending substantially the entire length of the machine and adjacent the lower edge of said recessed portion, two worktables on which workpieces may be mounted, each said table being pivotable about and displaceable while in a vertical plane along said pivot member, separate drive means to effect the displacement and pivotal movement of the tables, means cooperating with said pivot member for retaining each of said worktables in a horizontal or a vertical position, whereby each said table may be securely supported at and moved between a substantially horizontal loading or unloading position at said station and a substantially vertical machining position in which it is received in said recessed portion.
Claim 3
Dependent Claim
91 words
A machine as claimed in claim 1 wherein at the juncture of said frame member and each said station there is a supporting bracket mounted to pivot about said pivot member with the respective table, a semicircular guide for each bracket spaced from said frame member, said bracket including a guide slot at its outer end, each table being formed with a projection on its rear surface adapted to be received for sliding engagement in said guide slot when said table is being pivoted and moved to or from said station.
Claim 4
Dependent Claim
29 words
A machine as claimed in claim 1 wherein a supporting column is provided for supporting each able at its said station when said table is in its horizontal position.
Claim 5
Dependent Claim
40 words
A machine as claimed in claim 2 wherein each said supporting bracket is provided with a toothed rack, there being a pinion which is in mesh with said rack and is adapted to be driven by said pivotal drive means.
Claim 6
Dependent Claim
39 words
A machine as claimed in claim 2 wherein said projection on said table slidingly engages a lip in said recessed portion when said table is in said machining position or being moved toward and away from said machining position.
Claim 7
Dependent Claim
44 words
A machine as claimed in claim 2 wherein the drive means for the longitudinal displacement of the tables includes a motor and a drive member adapted to alternately engage said projection on each table, said drive member being slidably mounted in said frame member.
Claim 8
Dependent Claim
52 words
A machine as claimed in claim 2 wherein the projection on each table and the lip in said recessed portion are provided with cooperating ramp means to guide the movement of said table towards and away from at least one vertical reference surface in said recessed portion of on said frame member.
Claim 9
Dependent Claim
46 words
A machine as claimed in claim 7, wherein at least one jack is associated with each table adjacent said vertical reference surface to apply a vertical force on each table causing said ramp means to guide the table towards and away from said vertical reference surface.
Claim 10
Dependent Claim
20 words
A machine as claimed in claim 8 wherein said at least one jack is arranged within the said pivot member.
