'1 Claims. (01. 220-97) This invention has to do withtrays commonly known as starch trays such as are used with molds forthe making of candy and the like.
In the past, trays of this character have been made of wood or other fibrous material. It happens occasionally that regardle'ss of the care exercised in the making of candy when employing wooden trays, a splinter will appear in the candy. 'I'his is due to the fact that oftentimes in cleaning'the tray to remove all of the starch, a splinter of the tray will chip off or be scraped off and will mingle with the starch so that when. the latter is placed in the tray for another candy making operation, the splinter will be positioned in or form part of the wall of one of the .mold cavities and adhere to the molten material so that when the latter solidifies the splinter will be incorporated therein. 7
Another disadvantage of the wooden type of tray as heretofore used has been the lack of provision for proper circulation of air for cooling the pieces of candy which-have been poured. Trays of the character referred to heretofore in vogue have been further unsatisfactory for the reason that after a short term of use, due to the handling to which the same have been subjected, cracks and the like have appeared in the wood, allowing some of the starch to leak out. Thus such trays require constant attention for repairs and the like.
The above and other disadvantages of trays of previous constructions are obviated by the provision of a tray of the character forming the subject matter of the present invention. This tray is made preferably of metal and comprises a box-like structure including a metallic member having a bottom and four preferably plain walls,
. shelves on preferably two opposite sides, and feet ten candy or' the like. .fiuitable means also are preferably provided at said sides of the structure to serve as grips or handles.
Furtherobjects and advantages of the present invention will appear asthe description proceeds. Figure 1 is an isometric view showing aIstarch tray constructed in accordance with the principles of the present invention.
Figure 2 is a fragmentary enlarged sectional view taken approximately in the plane of line II-II in Figure 1.
Figure 3 is an enlarged fragmentary sectional view taken approximately in the plane indicated by the line III-III of Figure 1 but showing a pair of trays, one nested in the other.
Figure 4 is a fragmentary enlarged sectional .view taken approximately in the plane indicated by the line IV-IV in Figure 3, certain parts being broken away to more clearly disclose certain details.
Figure 5 is an enlarged fragmentary plan view of the upper edge of a cornerof the tray with parts in section to better illustrate the specific construction. 4
Referring now more particularly to the drawing, it will be observed that the tray comprises five pieces consisting'of a box-like member 1, two supporting members or legs 2, and two shelf members 3. 7
The box-like structure 1 has a floor 4 and walls 5 and 6, the latter provided with extensions '7 in the form of flaps which are bent against the end portions of the walls 5 exteriorly thereof and secured'thereto by soldering, spot-welding or the like, so thatthe box member 1 is rendered leak proof.
Each leg member 2 is of a length substantially commensurate with one of the walls 3 and is of greater height than the wall 3 to provide a marginal portion 8 whose function will appear as the description proceeds. Each supporting member 2 is preferably substantially U-shaped in develop- 'ment, each of the branches or legs being trans versely formed into a flanged channel shaped member constituting a foot 9, its flanges 10 lying preferably flush against the bottom 4 of the boxlike structure 1. One of the flanges 10 connects the foot 9 to the wall 2a of the supporting member 2. 5
Each shelf member 3 is of a substantially flanged angle construction comprising a seat 11,
an apron 12, an upwardly extending flange 13 adapted to fit against the interior of the wall 6 of the box-like structure 1, and a horizontal flange 14 which rests flush on the bottom 4 of the box 1. The shelf 3 is so formed that when positioned as shown in the drawing, its upper edge is substantially flush with the upper edge of the wall 6 of the box 1,'as shown in Figure 3.
The tray is assembled as follows:
The box-like structure 1 has its marginal porshown in Figuresl and 4. The walls 5 have return bent portions 5a as shown in Figures 1 and 2 to provide a smooth finished edge at 512, thereby obviating the danger of injury to the hands in handling. The ends of the margins 5a terminate short of the walls 6 by substantially twice the thickness of the sheet metal employed in this construction, or, by the combined thickness of the flange 13 of the shelf 3 and the extension or marginal portion 8 of the wall 2a.
After completion of the box structure 1, the
shelf members 3 are positioned as shown in the drawing, the ends of each of said members engaging the walls 5 as seen especially in Figures 1, 2 and 4. The flange 13 is spot Welded or otherwise suitably secured to the upper marginal portion of the wall 6 of the box structure 1.
Lastly, the supporting members 2 are formed as shown, except that each extension designated 8 in the drawing is initially located in the plane of the wall 2a as shown at 8:1 in Figure 3, the wall 2a engaging the wall 6, and the flanges 10 of the'feet 9 engaging the bottom surface of the floor 4 of the box-like structure 1, the marginal flange 10 being positioned'in juxtaposition to the marginal flange 14 of the shelf member 3. The flanges 10 and 14 and intervening portions of the box floor 4 are secured together by spot-welding or the like,
and the extension 8 is bent over the upper edge of the wall 6 and the adjacent portion of the flange 13 and downwardly over the latter so that said extension 8 terminates adjacent the seat 11.
The edge 15 thus formed is smooth and is preferably in the same plane withthe edges 52). To facilitate handling of the tray, a longitudinal opening 16 may be provided in the walls'2a of the supporting member 2. The space 1'7 between the feet 9 of each supporting member 2 is provided to receive a projecting bar of a conveyor whereby relative movement between the tray on the conveyor is prevented.
It will be notedthat by the above described construction, a starch tray of sheet metal or similar material which will not leak may be constructed in accordance with the principles of the present invention. This tray may moreover be easily cleaned of all starch or other materials and may be washed with a disinfectant without leaving any traces of the latter when the tray is dried, in contradistinction to the tray of wood or other porous material.
It will moreover be noted that the arrangement of the feet 9 and seats 11 is such that any desired number of trays may be nested as shown in Figure 3, whereby the trays may be neatly arranged in such a manner asto allow free circulation of air through the molten candy or the like so that the same may be hardened without needless delay.
The tray is used in the art of candy making and the like in much the same manner in which flasks are employed in foundry work, the tray being substantially fllled with powdered starch corre sponding with the sand employed in foundry work r for metal casting, and receives an impression from a pattern having projections corresponding to the shape of the pieces of candy to be made. The pattern is removed, leaving a number of holes, into which the hot candy or like syrup is poured; The trays are then arranged in nested relation as shown in Figure 3, and after the candyhas hardened sufficiently, the entire contents of the tray, including both the starch and the candy are placed in acoarse screen, allowing the starch to pass therethrough but retaining the candy. Each tray is thereupon thoroughly washed so that all traces of starch are removed. The tray is then ready to be used again. Due to the absence of leakage of the starch from the tray, the process involved in the making of the candy is extremely neat. The absence of projecting parts is further advantageous since the likelihood of any part of the tray catching in clothing or the like is eliminated.
If desired, suitable rubber or like inserts (not shown) may be attached in the openings 16 for comfort in handling.
I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles 'of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
