| 摘要 | An implement for distributing and leveling top dressing material on ground surfaces in which a generally horizontal frame is operated forth and back by a handle, and includes a fore and aft central runner with laterally extending frame bars, which runner and bars support a forwardly bowed blade for initially engaging the material, and a rearwardly bowed but relatively longer blade arranged to engage material discharged around the outer ends of the forward blade. The runner edges project slightly below the bottom edge levels of the two blades to serve as a directional guide for the implement, and the two blades are preferably formed of semiresilient material so as to provide limited horizontal flexibility without permitting any substantial vertical yield to the bottom edges of the blades. | ||||||
| 权利要求 | 1. An implement for manually spreading material on the ground, comprising; a. a horizontally disposed frame composed in part of a centrally arranged fore-and-aft runner beam, b. a pair of side beams rigidly attached to the runner beam, intermediate the ends thereof, and extending laterally outwardly therefrom, c. a forwardly bowed front leveling blade attached at a point between its ends to the forward end of the runner beam, and with the outer ends of said blade being attached to the respective side beams at points inwardly of their outer ends, d. a rearwardly bowed rear leveling blade attached at a point between its ends to the rear end of the runner beam and with its outer ends attached to the respective side beams at points outwardly beyond the points of attachment of the front blade to the side beams, and e. a handle connected to the runner beam for operating the implement. 2. The implement set forth in claim 1 wherein the runner beam is disposed between the outer end portions of the leveling blades and projects down below a plane passing horizontally through the lower edge of said outer blade end portions. 3. The implement set forth in claim 1 wherein the baldes are made of flexible sheet material whereby the portions thereof between the points of attachment to the runner and side beam may yield in resPonse to pressures of materials worked on during the operation of the implement. |
