OTTO A. REDDEMAZHN, F KERMAN, CALIFORNIA.
RAISIN-DRYING TRAY.
Application filed March 1, 1923. Serial No. 622,140.
To aZZ whom it may concern:
Be it known that Orro A. REDDEMANN, a citizen of the United States, residing at Kerman, in the county of Fresno and State of California, has invented certain new and useful Improvements in Raisin-Drying Trays; and he does hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to raisin drying trays and has for an object to provide an improved type of tray which shall drain the accumulated water from rains or other precipitation, to prevent the accumulation from affecting the raisins being dried upon the tray. It is well known in raisin culture that the grapes are picked and laid or piled upon devices known as trays, stand- 5 ing upon the ground in the vineyard. As
at present practised, these trays are preferably composed of wood, but the wooden trays are expensive and comparatively few of the raisin producers can afford to employ such trays. As a substitute for the wooden trays, raisin producers employ at present trays consisting of a sheet of tough paper laid upon the ground with the fruit laid or piled upon the paper. Subject to turning and other manipulation, these trays with fruit continue to lie upon the ground until the grapes have been cured to raisins.
The paper trays thus employed are satisfactory so long as there is no rain or other precipitation but in view of the fact that the paper lies directly upon the ground which is, of course, uneven the weight of the raisins thereon depresses the paper into the depressions of the ground, forming depressions for the retention of water. Water contained in these depressions seriously affects the fruit, serving at some periods at least to rot the fruit and at other periods to be detrimental to its quality.
The present invention, therefore, is intended to replace the cheaper and more ordinarily employed paper trays by a tray which will be self-draining and eliminate the necessity, as now practised, of going over the vineyard with a sharp puncturing point to punch holes in the depressed parts of paper to drain off the water.
To this end the invention comprises a sheet of paper shown in perspective at Figure 1 VIGWS.
As heretofore noted, the raisin tray which forms the subject matter of this application comprises a sheet of material 10. In practice this sheet will be paper, but the invention is not in any way limited to paper as a material, including any pliable sheet which may be provided with the perforations 10 as shown. These perforations 10 will be spaced at such intervals as will insure the drainage of allsections of the sheet, irrespective of depressions by reason of the weight of the superposed fruit and the un evenness of the ground.
As shown at Figure 4;, bosses will be formed by the production of the perforations, such bosses providing, as will be noted, depressions or dishing immediately surrounding the perforations so that by employing slight care in the operation that side of the sheet containing the dishing will be uppermost, assisting in the prop-er drainage of the water from the upper side of the 7 tray.
The employment of paper trays in raisin culture is so well understood that a further description will be unnecessary to a complete understanding of the use and opera.
tionof the device.
What I claim is:
A raisin tray comprising a sheet of flexible material having perforations there through at spaced intervals, said perforations forming depressions in the material surrounding saidv perforations and communicating therewith.
In testimony whereof he hereunto affixes signature.
OTTO A. REDDEMANN.
