| 摘要 | A flexible reinforced power transmission belt having rigid connectors molded into the cutter belt at spaced intervals. A cutter element is pivotally connected to the protruding end of each connector. A compressed resilient pad between the belt and cutter element urges the cutter element in an extended position but is deformed in response to abnormal impact to permit pivoting of the cutter elements. | ||||||
| 权利要求 | 1. A power transmission belt adapted to be driven by a drive pulley comprising a molded elastomeric material, a flexible jacket confining said elastomeric material to define an elongated belt member, a connector having one end molded into the elastomeric material, said one end terminating in the belt at the approximate neutral axis of the belt, a second end extended through the jacket to the exterior of the belt member, and means for connecting a work piece to the connector. 2. A power transmission belt as defined by claim 1 wherein the said one end of the connector forms a cross bar, and including a row of reinforcing filaments in the elastomeric material between the cross bar and said second end of the connector to inhibit removal of the connector from the belt. 3. A cutter belt adapted to be driven by a drive pulley comprising a carrier belt, a connector securely fastened to the belt, a cutter element pivotally connected to the connector, and a compressed resilient pad urging the cutter elemeNt in an extended position. 4. A cutter belt as defined by claim 3 wherein the resilient pad is a spring washer between the belt and the cutter element. 5. A cutter belt as defined by claim 3 wherein the connector is provided with a cross bar at one end, said one end being molded in the belt the approximate neutral axis of the belt. 6. A cutter belt as defined by claim 5 wherein the carrier belt is a V-Belt, the connector having its other end protruding through the top of the V-Belt and reinforcing filaments in the belt between the cross bar and the top of the belt. 7. A cutter belt as defined by claim 3 wherein the cutter element has a blade portion, said blade portion defining a plane that is angularly offset from the longitudinal axis of the carrier belt, said angular offset provided to center the center of gravity of the cutter element substantially over the longitudinal axis of the carrier belt. 8. For use on an impact cutting mower apparatus having a cutter bar with drive and reverse sheaves and front and rear idler sheaves all of which are adapted for mounting a driven cutter belt, a cutter belt comprising; a flexible carrier belt formed from a reinforced V-belt, rigid cutter elements fastened to said carrier belt, said cutter elements having a keel inserted into the carrier belt, a blade pivotally connected to the keel, and releasable supporting means supporting the blade in an extended position, said supporting means being released by an impact force produced when the blade strikes a solid object. 9. A power transmission belt adapted to be driven by a drive pulley comprising a molded elastomeric material, a flexible jacket confining said elastomeric material to define an elongated belt member, a connector having a stem and cross bar, said connector being securely fastened to the belt member with one end of the stem terminating in the belt at the approximate neutral axis of the belt, the cross bar fastened to said one end having dimensions transverseto the stem substantially greater than the cross section of the stem; the other end of the stem of the T-connector extended through the jacket to the exterior of the belt member, and means for connecting a work piece to the connector. 10. A power transmission belt adapted to perform other work in addition to its normal function of power transmission comprising a carrier belt, a working element, fastening means to fasten the working element to the carrier belt, and a compressed resilient pad between the working element and carrier belt to maintain the fastening means in tension. |
