11 Claims.

but preparatory to refilling the device with water for forming additional ice blocks the divider plates must be manually returned 'to their respective ice block forming positions.

This invention contemplates an improvement upon the above-mentioned device in that the ice blocks are not only automatically dispensed one by one but the divider plates are also automatically returned to their original or iceblock forming positions.

It is also an object of this invention to produce such an ice block forming and dispensing device which is of simple structure, cheap to manufacture, and easily and efficiently operated.

In the drawings: Fig. 1 is a plan view partly in section showingthe device with one ice block channel loaded ready for dispensing and the other with the plates in their respective positions after all the iceblocks have been discharged.

Fig. 2 is a section along the line 2-2" of Fig. 1.

Fig. 3 is a front elevation of the device showing the operating handle in its three operating channels 2 and 3 by and fixed to the plates 8 which are fixed to the forward ends of the side walls 4 and 5 of the tray.

To form ice blocks each of the channels 2 and 3 are divided into ice block forming spaces by the, divider plates 5, II], II, I2, I3; I4, I5 and I6. The divider plates, as shown particularly in Figs. '7 and 8, are mounted upon a square tube I1 which passes through openings I8 provided therefor in each of the divider plates. The divider plates are provided with spring clutch fingers I9 which project outwardly and forwardly from the forward face of the plates and yieldably engage the opposite side walls of the tube IT. For the purposes of this description the ice block dispensing or outlet end of the tray is considered the forward end ofthe tray.

It will be noted that due to the inclination of these clutch fingers I9 with respect to the tube I'I that the tube I! will move freely forwardly or to the left, as viewed in Figs. 1 and:

7, of the divider plates but upon reverse movement the fingers I9 will tend to clutch the tube I! with greater force and friction than when the tube is moved forwardly. Thus whenever the tube I 1 is moved rearwardly the'divider plates will be carried with it unless-sufiicient re-. sistance is o'fiered which will cause the tube I 'I to slide with respect to the fingers I9 in spite of their slip clutch action. provided in the form of a plurality of stops 29, 30; SI, 32, 33, 34, and 36.

It will be seen that there is provided a pair of stops for each of the divider plates. The dispositions, I 35 tance between each pair of stops decreases from Fig. 4 is a section along the line 4'-4 of the forward to the rear end of the tray, that is, Fig. 2. stops 29 are slightly farther apart than stops Fig. 8 is a detail showing the arrangement for selectively positioning each of the divider plates in its proper ice block forming position.

Referring more particularly to the drawings there is shown a sheet metal tray generally designated I provided with channels 2 and 3 in which the ice blocks are formed, side walls 4 and 5 andend wall 6. channels 2 and 3 are open. A support plate 'I is positioned forwardly of'the; open end' of 'the The forward ends of the 30, stops 30 farther apart than stops3l.

gether than the pair of stops immediately forward thereof. The stops 29 through 36 conveniently take the form of side plates 31 and middle plate 38 which are cut to shape and fixed to the top of the tray above and lengthwis of the channels 2 and 3. Each of the divider plates is arranged so that the width of its upper end is greater than the distance between its respective pair of stops and less than the distance between the stops forwardly thereof. Thus the distance between the vertical edges 40 of the plate I5 is greater than the distance between its respective stops 35 and less than the distance between the stops 34. Thus the width of the upper portion of each plate, that is, the dis.-

This' resistance is In other words, each pair of stops is closer to-:

tance between its vertical edges, is less than the width of the plate forwardly thereof.

Although the divider plates slide relative to the tube l1 they cannot turn thereon due to the An ejector is fixed to the end of the tube [1 and a closure plate 46 with a rubber sealing gasket 41 for the front or open end of the channels 2 and 3 is slidably mounted on the tube I1 and normally retained in closed position by the stop lugs 48 which back up and position the 010- sure plate 46.

The tube I1 is slidably mounted on the fixed rod 43 one end of which is fixed as at 44 in'the rear end wall 6 of the tray and the forward end of which is supported on the plate 7. The forward end. of the fixed rod 43 is reduced as at 49 and has slidably mounted thereon the thrust screw 50. The thrust screw 50 is brazed or otherwise suitablyfixed to the tube 11 as at 5|. nut 52 is screwed upon the screw 50. A handle 53 is swivelled to the nut 52. The nut 52 is provided with opposed fingers 54 which form a rotary-bolt. I

A keeper 55 adapted for interengagement with the rotary bolt 54 is secured to the support 1.

As shown in the full lines, right hand side of Fig.3, the handle 53 is in vertical position and the bolt 54 is interengaged with the keeper 55. If the handle 53 is turned. counter-clockwise ninety degrees to the dotted lineposition, the rotary bolt is turned from the horizontal to thevertical and disengaged from the keeper 5.. This permits the tube I! to be pulled outwardly or to the left,

Fig. 1. v

The operationof the device is as follows: In the lower half of Fig. 1 the device is shown in ice block forming'position with the divider plates l0 spaced, the closure 46 closed and the handle 53 inivertical position with the rotary bolt 54 horizontal' and'interengaged with keeper 55. After thefiice is formed and while the tray 1 is still in the sharp freezing compartment of the refrigerator, the handle 53 is turned counterclockwise,

Fig. '3,: approximately forty-five degrees. .Since,

theJsquaretubeJT cannot be turned and the screw50. isfixed to the tube I1, therefore the screw 50 cannot turn.. Since thevnut 52 and 'bolt 54 are [still interengaged withthe keeper 55 and cannot move outwardly or toward the left, Fig. 1,

thuslas the nut 52 turns forty-five degrees .on

the screwi50, the screw 50 and the tube I! move forwardly or toward. the left a short distance, about one-sixteenth of an inch. The turning of nut 52 on screw 50, due tothe mechanical advantage thereof, exerts aconsiderable forward .or leftward pull,-Fig. 1, onthe tube .||:which;de taches the ejector plate 45 from the end wall 6 to which it might be frozen, breaks loose the ice blocks from the: side and bottom walls of their respective channels 2 and 3, and slightly opens theclosure 46. The handle 53 is now turned another forty-five degrees to the horizontal position shown in dotted lines Fig. 3, which disengages the rotary bolt 54 from its keeper. The handle 53 maynow be pulled forward or to the left carryingwith itthe entire column of ice The distance between the rubbergasket on the closure '45 from the outer edge 5| of channel 3 (when the closure 46 abuts the guide 60, Fig. 5) is less than the length of two ice blocks 62 plus the thickness of one divider plate between them. Thus only one ice block 62 will be entirely forwardly of and free from the discharge end 6| of the channel 3. The second ice block 62a is retained by the forward edge 6| of the channel.

The ice blocks are disconnected from the divider plates by the inclined surface 63 as explained in my copending application Serial No. 276,530, filed May 31, 1939. The first ice block 62 will be released as soon as the operatorceases to pull on the handle 53. If the handle is again pulled forwardly or to the left, divider plate 9 is drawn against the closure plate 46 and the second ice block 6211 is discharged upon easing the pull on the handle 53. This method of operation is repeated until all of the ice blocks are discharged and the divider plates will be stacked in the position shown in the upper half of Fig. 1. The forward oriejecting movement of handlev 53 is arrested, when the last ice block is discharged, by the ejector plate 45 abutting the stops 65 at the forward or outlet end of the channels.

To reload thev tray, the handle 53 is pushed rearwardly or to the right, Fig. 1. The clutching engagement between. the fingers l9 and the square. tube ll causes the plates to moverearwa'rdlyior to the right. As the tube I! moves to theright the stops 29 through '36 inclusive select orjarrest. their corresponding divider plates ,9 through l6 and, position them in their properly spaced relation. .As soon as the ejector plate l5 abuts the end wall; 6 the handle 53 is turned fromtheyertical position, Fig. 3, full line to the horizontal position,; dotted line showing Fig. 3. Du1:ing;the, last forty-five degrees of clockwise turning of the handle 53 the threaded engagement'of nut, 52 andscrew50 causes the plate 4 6 and gasket 41 to be drawn tightly against the outlet end of the channel 3. Obviously since the ice forming and dispensing mechanism is identie cal for; both ofthe channels Z and 3, the operation Of these mechanisms is identicaland the description of the one applies equally well to the r- In reloading as the tube I? is moved rearwardly or to the right stops 48 abutclosure 46 and force it into closing relation with the discharge endofth'etray.
