Abstract
Abstract The manipulator includes a stationary tipping trough including a pair of longitudinally spaced substantially angular supporting surfaces each having a downwardly and inwardly sloping inlet side and an upwardly and outwardly sloping steeper outlet side. A apir of tipping levers are oscillatable by an associated fluid pressure actuator to engage a longitudinal corner edge of a billet in the tipping trough to tilt the billet so that it rests on a different side. A pair of lifters, having projecting fingers, are oscillatable about the same axis as the tilting levers by a different fluid pressure actuator so that the fingers engage the then lower side of a billet in the tipping trough and move the billet over the outlet sides of the supporting surfaces. The tipping trough preferably is arranged between a billet feeding roller conveyor and a billet discharge roller conveyor, and switch means are provided for engagement with a billet moving along the feeding conveyor. The billets have sloping ends providing respective projecting noses and the switch means are so arranged that, depending upon which switch is engaged by a sloping nose, an appropriate billet tipping operation is initiated. Alternatively, the switch means may be arranged beneath a billet support surface, again for corporation with the nose of a billet, or may be arranged to project into the tilting trough for engagement by the nose of a billet.

Claim 1
Independent Claim
286 words
In a manipulator for polygonal cross-section billets, particularly cast copper bars, having a tipping trough for tilting of the billets and means for feeding the billets to the tipping trough and for receiving billets from the tipping trough: the improvement comprising, in combination, a single tipping trough having at least one pair of stationary angularly related supporting surfaces intersecting at substantially right angles to each other to form a substantially V-shaped apex and each forming an uninterrupted stable supporting surface for billets moved sidewise into and out of said trough; one of said surfaces sloping upwardly and outwardly from said apex at a relatively small angle and normally serving as a billet receiving side of said trough; the other surface sloping upwardly and outwardly from said apex at a steeper angle and normally serving as a billet discharging side of said trough; each polygonal crosssection billet, when moved sidewise into said trough, abutting one of said stable supporting surfaces and having one side surface thereof stably supported on the other of said stable supporting surfaces; and at least one tipping lever pivotally supported in said manipulator adjacent said tipping trough and having a free end engageable with a longitudinal corner edge of a polygonal cross-section billet then in said tipping trough to tilt the billet about its longitudinal axis to bring a different side surface of the billet into stably supported relation with the stable supporting surface previously engaged by said one side surface; said tipping lever being repetitively oscillatable to tilt the billet an unlimited number of times to bring selected side surfaces of the billet into stably supported relation with the stable supporting surface initially engaged by said one side surface of the billet.
Claim 2
Dependent Claim
286 words
In a manipulator for polygonal cross-section billets, particularly cast copper bars, having a tipping trough for tilting of the billets and means for feeding the billets to the tipping trough and for receiving billets from the tipping trough: the improvement comprising, in combination, a single tipping trough having at least one pair of stationary angularly related supporting surfaces intersecting at substantially right angles to each other to form a substantially V-shaped apex and each forming an uninterrupted stable supporting surface for billets moved sidewise into and out of said trough; one of said surfaces sloping upwardly and outwardly from said apex at a relatively small angle and normally serving as a billet receiving side of said trough; the other surface sloping upwardly and outwardly from said apex at a steeper angle and normally serving as a billet discharging side of said trough; each polygonal crosssection billet, when moved sidewise into said trough, abutting one of said stable supporting surfaces and having one side surface thereof stably supported on the other of said stable supporting surfaces; and at least one tipping lever pivotally supported in said manipulator adjacent said tipping trough and having a free end engageable with a longitudinal corner edge of a polygonal cross-section billet then in said tipping trough to tilt the billet about its longitudinal axis to bring a different side surface of the billet into stably supported relation with the stable supporting surface previously engaged by said one side surface; said tipping lever being repetitively oscillatable to tilt the billet an unlimited number of times to bring selected side surfaces of the billet into stably supported relation with the stable supporting surface initially engaged by said one side surface of the billet.
Claim 3
Dependent Claim
61 words
In a manipulator for polygonal cross-section billets, the improvement claimed in claim 1, including at least one billet lifter engageable with at least one side surface of a billet in said trough to discharge the billet along a respective one of said uninterrupted stably supporting surfaces of said trough; each lifter being associated with one of the sides of said trough.
Claim 4
Dependent Claim
43 words
In a manipulator for polygonal cross-section billets, the improvement claimed in claim 2, in which each lifter comprises a wheel having plural projections extending from its circumference; and means mounting each wheel for rotation about an axis extending parallel to said tipping trough.
Claim 5
Dependent Claim
