Abstract
Abstract A core handling apparatus for supporting a core or log for horizontal longitudinal advancement along a path past various tool heads operable to cut the core or log into a plurality of studs and chips. The core and log handling apparatus includes structure operable to move cores or logs along a predetermined path, independent of any displacement of the core or log other than longitudinally of the path, and the tool heads are disposed along the intended path of movement of the associated cores and logs and operable to sequentially chip material from the opposite sides of the cores or logs to form parallel opposite side planar faces on the cores or logs, chip material from the upper and lower portions of the cores or logs to form planar parallel upper and lower surfaces on the cores or logs, and form at least one horizontal kerf through the cores or logs after the latter have been shaped.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
231 words
Apparatus for use in connection with rotary chipping heads for forming planar side surfaces on a peeler core or log workpiece, comprising a. a frame; b. workpiece support means connected with said frame, said support means including a pair of parallel spaced horizontal upstanding support flanges (30) having laterally spacEd upper marginal edge portions for slidably supporting and cradling the workpiece; c. means (14) for introducing the workpiece longitudinally upon said support flanges; and d. upper holddown and drive means for driving said workpiece longitudinally of, and for biasing said workpiece downwardly upon, said support flanges, said upper holddown and drive means including 1. drive wheel means (48) connected for free vertical movement relative to said frame, said drive wheel means applying to said workpiece a downwardly directed force of such a magnitude as to cause the adjacent upper marginal edge portions of said support flanges to score and form shallow longitudinal grooves in the workpiece; and 2. motor means (58) for driving said drive wheel means, whereby the workpiece is positively supported between said drive wheel means and said support flanges and is prevented from lateral or rotational movement relative to said support flanges by the cooperation between the upper marginal edge portions of said support flanges and the shallow grooves formed in the bottom of the workpiece, thereby to permit accurate chipping of the workpiece by said chipping heads.
Claim 2
Dependent Claim
231 words
Apparatus for use in connection with rotary chipping heads for forming planar side surfaces on a peeler core or log workpiece, comprising a. a frame; b. workpiece support means connected with said frame, said support means including a pair of parallel spaced horizontal upstanding support flanges (30) having laterally spacEd upper marginal edge portions for slidably supporting and cradling the workpiece; c. means (14) for introducing the workpiece longitudinally upon said support flanges; and d. upper holddown and drive means for driving said workpiece longitudinally of, and for biasing said workpiece downwardly upon, said support flanges, said upper holddown and drive means including 1. drive wheel means (48) connected for free vertical movement relative to said frame, said drive wheel means applying to said workpiece a downwardly directed force of such a magnitude as to cause the adjacent upper marginal edge portions of said support flanges to score and form shallow longitudinal grooves in the workpiece; and 2. motor means (58) for driving said drive wheel means, whereby the workpiece is positively supported between said drive wheel means and said support flanges and is prevented from lateral or rotational movement relative to said support flanges by the cooperation between the upper marginal edge portions of said support flanges and the shallow grooves formed in the bottom of the workpiece, thereby to permit accurate chipping of the workpiece by said chipping heads.
Claim 3
Dependent Claim
73 words
motor means (58) for driving said drive wheel means, whereby the workpiece is positively supported between said drive wheel means and said support flanges and is prevented from lateral or rotational movement relative to said support flanges by the cooperation between the upper marginal edge portions of said support flanges and the shallow grooves formed in the bottom of the workpiece, thereby to permit accurate chipping of the workpiece by said chipping heads.
Claim 4
Dependent Claim
73 words
motor means (58) for driving said drive wheel means, whereby the workpiece is positively supported between said drive wheel means and said support flanges and is prevented from lateral or rotational movement relative to said support flanges by the cooperation between the upper marginal edge portions of said support flanges and the shallow grooves formed in the bottom of the workpiece, thereby to permit accurate chipping of the workpiece by said chipping heads.
Claim 5
Dependent Claim
80 words
Apparatus as defined in claim 1, wherein the adjacent upper marginal edges of said support flanges are spaced apart by a distance of approximately 3 inches, and further wherein said drive wheel means include a toothed outer periphery, the downwardly directed force of said drive wheel means being sufficient to cause the toothed periphery of said drive wheel means to bite into the workpiece and thereby support the upper portion of the workpiece against lateral movement relative to the frame.
Claim 6
Dependent Claim
44 words
the axial spacing distance between the disks of successive drive wheels in the direction of travel of said workpiece being progressively reduced, whereby said toothed wheel disks engage the workpiece along separate parallel and spaced apart paths extending along the top of the workpiece.
Claim 7
Dependent Claim
44 words
the axial spacing distance between the disks of successive drive wheels in the direction of travel of said workpiece being progressively reduced, whereby said toothed wheel disks engage the workpiece along separate parallel and spaced apart paths extending along the top of the workpiece.
Claim 8
Dependent Claim
122 words
Apparatus for use in connection with rotary chipping heads for forming planar side surfaces on a peeler core or log workpiece, comprising a. a lower support assembly including a pair of parallel spaced horizontal upstanding support flanges (30) having parallel upper marginal edge portions for lengthwise slidingly supporting and cradling the workpiece; b. means (14) for introducing the workpiece longitudinally upon said flanges; and c. an upper holddown and drive assembly including a plurality of upper holddown and drive means (48, 50, 52) spaced longitudinally above said support flanges for frictionally and drivingly engaging said workpiece and for yieldingly resisting upward movement of said core relative to said flanges, thereby to prevent lateral shifting of said workpiece relative to said support flanges,
Claim 9
Dependent Claim
122 words
Apparatus for use in connection with rotary chipping heads for forming planar side surfaces on a peeler core or log workpiece, comprising a. a lower support assembly including a pair of parallel spaced horizontal upstanding support flanges (30) having parallel upper marginal edge portions for lengthwise slidingly supporting and cradling the workpiece; b. means (14) for introducing the workpiece longitudinally upon said flanges; and c. an upper holddown and drive assembly including a plurality of upper holddown and drive means (48, 50, 52) spaced longitudinally above said support flanges for frictionally and drivingly engaging said workpiece and for yieldingly resisting upward movement of said core relative to said flanges, thereby to prevent lateral shifting of said workpiece relative to said support flanges,
Claim 10
Dependent Claim
55 words
Apparatus as defined in claim 3, wherein said upper holddown and drive assembly includes at least three drive wheels, and further including between a pair of said drive wheels chipping head means (80, 82) for forming vertical planar side wall surfaces on opposite sides of said workpiece during transport by said holddown and drive assembly.
Claim 11
Dependent Claim
30 words
Apparatus as defined in claim 4, wherein said upper assembly includes means yieldingly urging each of said drive wheels downwardly toward a lower limit position spaced above said lower assembly.
Claim 12
Dependent Claim
16 words
Apparatus as defined in claim 5, wherein said support flanges are spaced apart approximately 3 inches.
