Abstract
Abstract A vibratory conveyor specially designed for ruggedness and ability to align elongated pieces of material and feed them through the infeed spout of a power driven chipper provides a virtually jam proof, maintenance free apparatus for reducing random length scrap lumber to chips suitable for use in pulp mills. The conveyor includes a screen section and a metal detecting section, the latter being arranged to stop the conveyor upon detecting any metal in material being fed to the chipper.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
A vibratory feeder and chipper for reducing scrap lumber to chips comprising: a. a chipper having an infeed spout; b. a substantially horizontal vibratory trough of substantial length having a discharge end that extends into the infeed spout of the chipper adjacent to the anvil of the chipper; c. rugged resilient means stressed in shear for supporting said trough for vibration in a vertical plane and stressed in compression for resisting lateral forces applied to said trough; d. means for guiding said trough along an inclined path in the plane of vibration; and e. drive means for reciprocating the trough along the inclined path.
Claim 2
Dependent Claim
104 words
A vibratory feeder and chipper for reducing scrap lumber to chips comprising: a. a chipper having an infeed spout; b. a substantially horizontal vibratory trough of substantial length having a discharge end that extends into the infeed spout of the chipper adjacent to the anvil of the chipper; c. rugged resilient means stressed in shear for supporting said trough for vibration in a vertical plane and stressed in compression for resisting lateral forces applied to said trough; d. means for guiding said trough along an inclined path in the plane of vibration; and e. drive means for reciprocating the trough along the inclined path.
Claim 3
Dependent Claim
49 words
A chipper feeder according to claim 1 in which the rugged resilient means comprises blocks of elastomer material compressed between generally flat surfaces of a first member on the trough and second members attached to a support, the surfaces extending parallel to the path of vibration of the trough.
Claim 4
Dependent Claim
38 words
A chipper feeder according to claim 1 in which the rugged resilient means comprise blocks of elastomer material compressed between generally flat vertical surfaces of the trough and a base extending parallel to the length of the trough.
Claim 5
Dependent Claim
40 words
A chipper feeder according to claim 1 in which the trough is divided into sections, one of which is adjacent the chipper, and a resilient connection between the section adjacent the chipper and the next preceding section of the trough.
Claim 6
Dependent Claim
19 words
A chipper feeder according to claim 1 in which at least a portion of the trough bottom is perforated.
Claim 7
Dependent Claim
25 words
A chipper feeder according to claim 1 in which the trough comprises at least one section of nonmetallic material to accommodate a metal detector apparatus.
Claim 8
Dependent Claim
33 words
A chipper feeder according to claim 1 in which the discharge end of the trough is resiliently attached to the preceding section of the trough and projects into the associated chipper infeed spout.
Claim 9
Dependent Claim
29 words
A chipper feeder according to claim 7 in which the discharge section includes a substantially vertical face adapted to absorb the lateral forces exerted by material entering the chipper.
