DOMESTIC AP PLIANCE FiledApril 30, 1924 of its operating positions.

Patented May 3, 1932 PATENT OFFICE RALPH L. LEE, OF DAYTON, OHIO, ASSIGNOR TO DELCO-LIGHT COMPANY, OF DAYTON, OHIO, A CORPORATION OF DELAWARE DOMESTIC APPLIANCE Original application filed March 31, 1923,8eria1 No. 629,202. Divided and this application filed April 30,

1924. Serial The present invention relates to endless belt type conveyors and particularly to conveyors for clothes wringers.

T he present application is a division of my copending application, Serial No. 629,202, filed March 31, 1923, which was issued January 22, 1929, as Patent No. 1,699,599.

One of the objects of the present invention is to provide an endless conveyor which can be readily uncoupled for the removal there-of.

Another object of the invention is to provide for minimizing the squirting of water from the conveyor as it passes between the Wringer rolls. I

Anotherlobject of the invention is to provide for maintaining a conveyor belt in alignment with the rollers with which the belt cooperates.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a pre ferred form of embodiment of the present invention is clearly shown.

In the drawings:

Fig. 1 is a fragmentary perspective view of a clothes wringer with my improved clothes conveyor appliedthereto;

Fig. 2 is a plan view of a portion of the conveyor showing the construction of the conveyor and the method of lacing same; and Fig. 8 is a fragmentary perspective view of the conveyor and lacing means.

9 Referring to the drawings, a clothes wringer is shown at 23 including the downwardly extending legs and 51 of the side frames of the wringer. 1V ringer rolls 68 and 69 are rotatably mounted between the legs. A drain board 58 is pivotally mounted to the legs of the wringer below the rolls 68 and 69 in any suitable manner. The drain board includes side frames 59 and 60.

Drainboard 58 is provided with a locking device for maintaining the board in either This locking device comprises a sliding pin 63 carried by the frame leg 50. Pin 63 has a notch 64- formed by flattening off a side of pin 63. A pin 65 inserted from the side of the frame leg 50 is received by the notch 64: and is adapted to cooperate with the ends of the notch to prevent the locking pin 63 from being pulled entirely out of the frame. Pin 63 cooperates with holes 66 and 67 in the side rail so as to lock the drainboard in either of its tilted positions.

The drainboard 58 provides a movable support for the movable wringer conveyor now to be described. At opposite end edges of the board 58. the rails 59 and 60 carry rollers located parallel to rolls 68 and 69, one of said rollers being shown at 96, it being understood that another is provided on the opposite side of the wringer 23. Rollers 96 are adapted to support a conveyor 97 interposed between the rolls 68 and 69 and therefore rotated by the movement of these rolls. Roller 96 is ta pered and the like roller (not shown) on the opposite end edge of board 58 is tapered so as to be larger in diameter at their centers than at the ends in order that, during the movement of the belt, the belt will remain in alignment with the wringer rolls.

To prevent gathering or crawling the conveyor belt 97 is preferably made of two thicknesses of fabric, such as canvas. In making the belt, the ends 97 a and 976 (shown folded back in the drawing merely for the purpose of showing the lower layer of the canvas) are brought together at the center of the belt. A strip of tape 98 is sewed through the side edges of the fabric to make a two-ply belt. Parallel stitchings 99 are provided lengthwise on the belt to hold the plies together so that said plies will together form a relatively stiff belt, so as to prevent the belt from gathering.

A series of spaced loops 101 are sewed to the one end of the conveyor belt 97 while spaced loops 102 are sewed to the other end of the conveyor belt. Loops 101 are adapted to fit within the spaces between the loops 102 while the loops 102 ar ada 'ited to tit within the spaces between the loops 101. A 0 stave 108 is inserted into the loops 101 and 102 to thereby lace the belt. Pairs of loops 104 shorter than loops 101 and 102 are located at each side edge of the belt. One of these loops 10 i is carried at each corner of it;

' of water will not be collected adjacentthe a 1 be trapped ano adjacent the lacing in order the end of the belt fabric so as to engage the notch end of the stave 103.

These small loops 10 1 provide means for lacing the belt at the side edges and prevent accidental removal of the stave. In lacing the belt the stave 103 is first inserted through loops 101 and 102 as is shown in Fig. 2. One of the notched ends is then inserted into the small'loops 104 at one side of the belt97.v After one side of the belt is connected the other notched end 105 is inserted within the loo is riiiderstood that the belt will stretch sidewise so that'the loops 104 can be stretched over a notched end 105. Both ends of the conveyor belt are reinforced by tape 106 and 107 secured by stitching.

Means are provided for preventing a large quantity of water accumulating between the plies at any one portion thereof, for example, to prevent a relatively large volume of water being squeezed out with considerable force and squirtedupon the floor, workbench, or the like. This means comprises devices for trapping small quantities of water in pockets to be progressively emptied so that the water will be squeezed out progressively and in relatively small amounts. By avoiding anaccumulation of water, the water squeezed out in small quantities will run down the con veyor belt onto the drainboard. To accomplish these aims of the invention the belt. 97 is provided with transverseor diagonal stitchings 108. These stitchings cooperate with stitching 99 to form water dispersingpoclb ets. The belt 97 is generally water soaked during the wringing operation and water tends to collect between the plies of the canvas. In order that a considerable quantity the slide edges.

104 on the other side of theb'elt. "It 7 The rolls therefore tend to grasp the belt more at the center than at the side edges, and, consequently, thebelt tends to track readily with the rolls.

It is to be understood that features of the present invention are adapted not only to clot-hes wringing apparatus but also to other apparatus involving a rolling action in the mode of operation, such as mangles having one or more rollers adapted tobe driven by a power device.

'While the form-of mechanism herein shown and described constitutes a preferred embodiment of one form of the invention, it isto be understood that other forms might be adopted and various changes and alterations made in the shape, size, and proportionof the elements therein without departing from the spirit and scope of the'invention.

What is claimed is as follows:

1. A wringer including a plurality of rollers. a conveyor belt having a plurality of plies and adapted for conveying articles between said rollers, means associated withsaid'conveyor belt and cooperating with said rollers for progressively and gradually removing liquid from between the plies of said belt.

2. A wringer including a plurality of rollers, a conveyor belt having a plurality ofplies and adapted for conveying articles between up said rollers, means associated with said conveyor belt and cooperating with said rollers for progressively and gradually removing liquid from between the plies of said belt, said means comprising stitching extending transversely to the direction of movement-of the belt. i

In testimony whereofjI hereto aflixmy signature.

lacing and there be squeezed out with considerable force, thediagonal stitchings 108 co operate with thelengthwise stitching 99 to form a seriesof pockets where the water will pushed in small quantities from between the plies of canvas. 1 When the belt 97 moves the water between the plies of canvas will be trapped and then pushed out of pockets 109. \Nhen the conveyor belt 97 moves so that a portion indicated by the dot and dash line 110 moves under the roll the water between the plies of canvas between the diagonal stitches 108 will be trapped and then pushed out of a series of pockets 111.

In this manner small amounts of water are 7 pushed out from between the plies of canvas at aplurality of places with relatively little force instead of collecting at one place and being squeezed out with relatively great force.
