Harter, Anthony Niewyk, Robert L. Judd and Hofgren, Wegner, Allen, Stellman & McCord ABSTRACT: Apparatus for releasably mounting a subdividing heated wire grid in the cabinet of an icemaker in which a slab of ice is formed and this slab transferred to the slab dividing grid all within the cabinet. This invention includes improved means including interengaging projections and projection receiving means such as slots together with movable catches for some of the slots with the result that the interengagement of the projections and slots provides effective but easily released mounting means for positioning the subdividing grid in the cabinet. The invention is particularly useful for large commercial icemakers in which there is located a plurality of the ice slab forming means positioned closely together vertically and in which the subdividing means or heated grid is located closely adjacent each vertical pair of slab forming means which in each instance is usually a refrigerant evaporator plate.
ICEMAKER CUTTER-GRID-MOUNTING MEANS One of the features of this invention is to provide an improved apparatus for releasably mounting a subdividing means in an icemaker cabinet so that the subdividing means. usually an electrically heated grid, may be readily fixed in position within the cabinet and removed as for servicing even though the space available is quite small and without requiring tools such as wrenches, screwdrivers or the like.
Other features and advantages of the invention will be apparent from the following description of one embodiment thereof as illustrated in the accompanying drawings. Of the drawings:
FIG. I is a front-elevational view of a commercial icemaker cabinet having ice slab subdividing means therein embodying the invention and with portions of the front door of the cabinet broken away for clarity of illustration.
FIG. 2 is a vertical-sectional view illustrating the releasable mounting apparatus on one side of the subdividing grid with this apparatus being shown in elevation.
FIG. 3 is a view similar to the top portion of FIG. 2 but illustrating the mounting apparatus in partially released position.
FIG. 4 is an enlarged fragmentary perspective view illustrating the procedure for operating the releasable mounting apparatus.
FIG. 5 is an enlarged fragmentary vertical-sectional view taken substantially along line 5-5 of FIG. 3.
FIG. 6 is a perspective view of a slidable catch on the mounting apparatus.
The icemaker 10 illustrated in FIG. 1 is similar to the icemaker of Ayres et al. U.S. Pat. No. 2,682,155, issued June 29, I954 and owned by the assignee of the present application. Such an icemaker has been widely accepted as an efficient apparatus for making large amounts of ice cubes automatically and continuously. In such an icemaker the ice is formed by flowing water over an evaporator plate to produce an ice slab which is then released from the plate and permitted to fall into a subdividing means usually in the form ofa heated electric resistance wire grid formed of wires heated to a sufficient temperature to melt and subdivide the slab into cubes.
In the icemaker 10 illustrated in FIG. I there are provided a plurality of inclined vertically spaced rails 11. These rails are spaced vertically from each other but are positioned close together as shown so that a large number of ice cubes may be formed simultaneously. The upper portions 12 of the rails support evaporator plates (not shown) that are inclined to substantially the same angle as the rails 11, as illustrated.
After the ice slabs have been formed they are released in the well-known manner and permitted to slide from the evaporator plates onto subdividing means or cutting grids 13 positioned beneath the lower ends of the parallel rails 11. In order to aid in removing each cutting grid 13 as desired as when ser vicing or cleaning or for any other reason each grid is provided with improved releasable mounting means.
The releasable mounting means for each grid 13 comprises a plurality of interengaging projections here shown as pins 14 and 15 and projection receiving means here shown as slots 16 and 17. The pins are located on the backwall 24 of the cabinet 18 of the icemaker l0 and on the inside (not shown) of the rails 11, and the slots are located on the frame of the grid 13 with this frame being a rigid structural member here shown as the sheet metal periphery of the grid 13.
As can be seen from the drawings each slot 16 has an entrance 20 while each slot 17 has an entrance 21. The slots 16 and 17 are located adjacent opposite ends of side parallel flanges 22 that extend upwardly from the front and rear sides 23 of the cutting grid frame 19. The rear side parallel flange 22, illustrated in FIGS. 2-5, is adapted to be located against the backwall 24 of the cabinet 18. The front side parallel flange, which is not shown since it is substantially the same as rear flange 22, is adapted to be located against the inside of the rails 11. In the illustrated embodiment the pairs of pins 14 and 15 extend inwardly of the cabinet from wall 24 and from the rails 11.
As shown the end slot 16 on each of the pair of flanges 22 is located adjacent a corresponding end of its flange and extends in a generally vertical direction. Each corresponding opposite slot 17 is at the other end of its flange 22 and extends essentially horizontally.
In order to releasably retain the subdividing means or grid in position in the cabinet 18 there are provided movable means for closing each entrance on a first set of projection-receiving means to prevent removal of the corresponding projections therefrom with the others of the receiving means including their entrances being unparallel to the first set of projectionreceiving means to block release of all the projections from the receiving means when the first set entrances are closed by the movable means. In the illustrated embodiment the first set of projection receiving means comprises the vertical slots 16 on the opposite side flanges 22. The others of the receiving means or slots are the opposite end slots 17 which are unparallel to the slots 16 in that slots 17 are horizontal.
The movable means for closing the entrances 20 to the first set of slots 16 comprises a catch 25 for each slot 16 slidably mounted on a flange 22 adjacent its slot 16. Each catch 25 as is illustrated most clearly in FIG. 6 includes an inwardly extending lip 26 adapted to underlie a horizontal portion 27 that interconnects the top of the cutter frame side 23 and the outwardly located upwardly extending flange 22. Each catch also includes an inwardly extending handle 28 adapted to be engaged by the hand 29 of the operator for sliding the catch along its flange 22. The catches mounted on the front side, parallel flange of grid 13, are not shown since they are mirror images of the catches 25.
Each flange 22 in the region adjacent a slot 16 is deformed as illustrated by a pair of dimples 30 or embossments so as to provide a friction resistance to the movement of the catch 25 as illustrated in FIG. 2. The detents retain the catch in a desired ready for assembly position during shipment of the grid 13. When each catch is in this pin locking position of FIG. 2 the pin 14 is retained in a pair of horizontal slots 31 in the opposite sides 32 of the catch. As illustrated, these opposite sides 32 are located against the opposite side surfaces of flanges 22 so that opposite side surfaces actually provide bearing surfaces for the movable catch. Although grid 13 is slightly inclined as shown in FIG. 1, the catches 25 and their mirror images adjacent the front of the cabinet are positively prevented from sliding off the lower ends of the flanges 22 due to vibrations caused by icemaker operation since the bight portions of the slots 31 will bear against the right side of pins 14 as indicated in FIG. 2. This would not be possible if the catches mounted on the front side parallel flange of grid 13 were not mirror images of the catches 25.
As described above, the subdividing means structural member 19 is a part of the peripheral frame of the grid means or cutting grid 13. A pair of opposite parallel sides 23 of this frame member are bent outwardly as shown at 27 and then upwardly to provide the mounting flanges 22. Then at one corresponding end of each flange 22 are located the vertical slot 16 and its slidable catch 25 while at the other end of each flange 22 is located the inwardly extending horizontal slot 17 with its entrance end 21 at the extreme end of the flange.
In mounting each of the plurality of cutting grids 13 in the narrow space available between each pair of vertically adjacent rails 11 it is only necessary to manipulate the grid 13 to locate the pins 15 at the inner ends of their horizontal slots 17 and to manipulate the grid so that the other set of pins 14 are located at the bottom of their slots 16. This can all be done quite easily as the grids are lightweight. With the pins in these positions in their slots it is then only necessary to grasp each catch 25 by its handle 28 and move the catch to the left, as shown in the drawings, so that each pin 14 is received in the opposite side slots 31 of the catch as shown. The cutting grid 13 is then securely locked in position as the catches 25 hold each grid at one end and the horizontal arrangement of the opposite slots 17 prevents removal of the other pins 15 therefrom.
The cabinet 18 is provided with a hinged door 50 to afford easy access for service or cleaning of the interior or the cabinet. Door 50 is hinged about a vertical axis adjacent the left edge 50a of door 50. The top, right edge, and lower edge of door 50 are identified by reference numerals 50b, 50c, and 50d, respectively. In the event it becomes necessary to remove a grid from the cabinet as for servicing, cleaning or the like, it is only necessary to open the door 50 by pulling on right edge 50c to obtain access to the interior of cabinet 18, and then hold the grid with one hand while moving the two opposite catches 25 to release positions or to the right as shown in the illustrated embodiment so that the left-hand end of the grid can be lowered to disengage its slots 16 from their pins 14 and then move the grid to the left to disengage the other pins 15 from their horizontal slots 17.
