A Collecting Hook for Yellow-Popular Fruit

Prior to the development of the tool, pictured below, for collecting yellowpoplar (Liriodendron tulipifera L.) fruits, a variety of other hooks, saws, and loopers were used. However, our experience was that the fruit which projected at odd angles or was partially shielded by branches was uncollectible with such tools. This might amount to as much 10% of the crop. We therefore devised the hook described herein. It is easily made from a blank of 2024-T4 aluminum plate, 1/4" by 6" by 6”. The approximate cost of this plate on an individual basis is $2.00 but if a large number of hooks were to be made, a blank 6" wide by the desired length could be used. An economic method in which to utilize the stock would be to invert every other pattern and insert one branch hook under the other - thus three hooks can be made from a 6" x 13" blank.
