11 Claims. (Cl. 68-210) usually involves about twenty minutes of hard manual work. In addition it is particularly inconvenient and diiicult to get at the last batch of garments.

It is, therefore, a general object of the present invention to provide in a cylinder having an end door, means for facilitating the removal of garments therefrom.

A further, more specific object of the invention is to provide in a device of the class described, means forming an unloading chute which is movalble from an inactive position parallel to one of the end walls of the cylinder to an angular position for guiding garments out of the cylinder door.

A still further object of the invention is to provide means for readily altering the effective outline shape o-f the unloading chute after it has been moved to unloading position so thai'l no corner spaces will be present between edge portions. of the chute and wall portions of the cylinder.

A further object of the invention is to provide a device as above described wherein the chute, when in inactive position for unloading purposes, forms an apertured partition for separating the main washing chamber from an auxiliary liquid discharge chamber, there being means for releasably locking the chute in partition-forming position.

A further object of the invention is to provide in a device of the class described and including a garment containing cylinder with longitudinally extending garment lifting ribs therein, means whereby the chute may be moved from inactive position to unloading position without interference from said ribs, and means whereby the chute member will iit properly with relation to said ribs in either of the two positions of the chute.

With the above and other objects in view, the invention consists of the improved garment unloadingdevice and all its parts and combinations as set forth in the claims and all equivalents thereof.

Referring more particularly to the drawings, the nume-ral I0 designates a suitable supporting frame mounted on legs Il. The frame has suitably journaled therein spaced shafts I?. Each shaft has rigidly connected thereto rollers I3. Each shaft may have a rigid sprocket wheel I4 thereon, and the sprocket wheels may be connected by an endlesschain, or in any other suitable manner, so that both of the shafts I2 ,are rotated when one of the shafts is driven from an outside source. The above described construction forms no part of thenovel sub-ject matter of the present application and is more completely illustrated infapplication Serial No. 479,559,V iiled March 18, 1943.

A washing cylinder or drum I5, which is located within a fixed outer casing I6, is positioned for rotation on a horizontal axis. The drum is equipped with external peripheral tracks I'I and is supported for rotation 'on the rollers I3 in the manner fully described inthe abovereferred to pending application. The rollers engage Within the tracks I'I, as shown in Fig. 1, and cause rotation of' the drum. Any other means may, of course, be utilized for causing such rotation.

The peripheral Wall portion I 8 of the cylinder or drum is preferably imperforate and the front end wall I9 is provided with a loading and discharge opening 20. The'opening 20 in the front end of Ythe drum is in registration with an opening 2I linthe 'front Wall of the casing I6.

The pin 15 projects rotatably through the other side of the chute 48 and on this other side an operating handle 16 (see Fig. 3) is keyed to the pin 15. Other Wings 11 and 18 are apertured as at 19 and 80 and have pivot bearing members projecting from one side thereof, as at 8| and 82. Pins 83 and 84 extending from the chute through the bearings 8| and 82 permit pivotal movement of the Wings 11 and 18. The bearing members 8| and 82 have gear segments 85 and 86 integral therewith and these segments are adapted to mesh with segments 81 and 88, connected to the bearing members 64 and 65 of the wings 60 and 6 I. p

As a result of the above described arrangement when the handle member 16 is in the position of Fig. 2, then the wings are all in a Withdrawn position as indicated by the dotted lines. It is to be noted that when the wings are withdrawn they are clear of the rib recesses 53, 54 and 55. When the partition and chute forming member 48 is swung to the unloading position shown by dotted lines in Fig. 1, then the wings may be moved fromy the Withdrawn position of Fig. 2 to the operative position of Fig. 4 by moving the handle from the position of Fig. 2 t-o the position of Fig. 4. This movement of the handle causes simultaneous spreading of all four Wings. It is to be noted that the wings 11 and 18 are notched, as at 89. This permits the garment lifting ribs 5| and 52 to intersect these wings, by way of the notches 89, as is clear from Fig. 1. The wing operating handle 16 is formed with a laterally opening pocket 90 which is positioned to accommodate the latching mechanism 58 and Vassociated parts when the handle is in the position of Fig, 4. Due to the novel wing construction the effective outline shape of the partition forming chute member may be quickly altered from the circular shape of Fig. 2 to the shape of Fig. 4, and it is to be noted that the shape -of Fig. 4 will perfectly fit the contours of the interior of the cylinder when the member 48 is in the angular chute forming position shown by dotted lines in Fig. 1.

Cooperable with the exterior of the perforated annular wall 29 of the auxiliary chamber 4| is a band valve 9| provided with operating mechanism 92 which is under the control of a hand lever 93. 'I'his mechanism is fully described in pending application Serial No. 419,559, filed March 18, 1943. The arrangement is such that when the operating lever 93 is in one position that a trip member 94 at the opposite end is disposed in such position as to trip the valve operating mechanism 92 and cause expanding movement of the band Valve 9| so that spent liquid can be discharged from the auxiliary chamber 4| and from the main washing chamber 40 through the openings 30 in the auxiliary chamber which are controlled by the band valve. When the hand lever 93 is in a reversed position, then the band valve will be closed.

Operation In use of the device,.and with the band valve in a position to close the apertures 30, the drum is rst filled with water and the other cleansing materials through the supply conduit 42. This liquid first enters the auxiliary chamber 4| and then passes through the openings 49 in the partition member 48 and through the openings 39 into the main chamber 40. The garments t-o be cleaned have, of course, been previously placed in the 'drum through the opening 20, and the door v28 has been closed. The partition and chute forming member 48 yis inthe fullline vertical position ofFig. 1 and is locked in said position by engagement of the latch 51 with therib lug 56. Upon. rotation `of the shafts |2 and rollers I3 the drum will be rotated at a desired speed for washing. After the washing action has taken place for a desired period and it is desired to remove the Washing liquid from the drum, the hand lever 93 is turned to the positionof Fig. 1 to bring the trip member 94 into the'position illustrated. As the drum rotates, one of the projecting arms of the valve band actuating mechanism 92 will engage the trip member 94 causing the band valve to be moved to the open position shown in Fig. 1. The spent liquid 4can now pass from the main washing chamber 40 into the auxiliary chamber 4|, through the openings in the partition 48 and through the openings 39, and can then escape from the peripheral openings 30 of the auxiliary chamber. This liquid passes into a suitable trough or drain pan from which it is directed to a point of discharge.

In order to remove the wet garments from the washing cylinder it has heretofore been necessary to reach manually into the opening 20 and withdraw wet heavy garments. In a large machine this takes a substantial length of time and there are also the diicultes of getting access to the last garments orV articles in the cylinder. With the present invention, however, after `the washing operation has been completed and with the door in open position, and with the latch mechanism 58 in an uppermost position, the latch is unlocked andthe partition is swung out to the position shown in Fig. 7, the garments being Vbelow the partition as indicated in said figure.

The latch may be readily released by using a pole similar to a window pole and by then pulling with the pole to cause movement of the carriage 44 and swinging of the partition to the position of Fig. 1. .The partition must loe swung out to the position of Fig. '1 while the cylinder is in the position of this ligure, as otherwise the garments would be trapped on the wrong side of the chute. When the Achute has been suitably disposed in proper angular position, then the handle 16 on the chute is'moved from the position of Fig. 2 to the position of Fig. 4 to cause spreading of the wings to the position of the latter ligure. This alters the effective outline of the member 48 so thatit conforms with the shape of the cylinder when the partition and chute forming member is in the` angular position. Afterv the parts-are in the position of Fig. '1 then the cylinder is rotated to bring it to the position of Fig. 8 which is also the same position indicated by dot-and-dash lines in Fig. 1. The garments cannow all be discharged through the door opening 29 in a few minutes time because the member 48 serves as an inclined chute so that the operation is aided by gravity. The wings and wing operating levers are all on the lower side of the chute and, therefore, do not interfere with the discharge of the garments. The operating handle 16 is onl the top side but it is in the straight position of Fig. 4 and is so formed that garments do not readily catch thereon. The space at the inner end of the main chamber 40 above the rear edge of the chute 48 is closed by the apertured plates 38 (Fig. 6). These plates prevent the garmentsfrom entering the auxiliary chamber when the cylinder is being rotated from the position of Fig. '1 to the position of Fig. 8 just before unloading.. The garments will, therefore, slide out on both sides of the handle 16 landoyer automatically engage to maintain the partition in vertical position until such time as the latch is subsequently released. i

`While the device is particularly useful inl c`n= nection with. Washing machines, where the dise charge of the heavy wetV garments presents a substantial problem, nevertheless the novel une loading chute. structure is useful inany garment l handling cylinder having an .end door'.
