The hous ing I2 is in turn mounted on a drive housing l3 which extends downwardly of one side _of the washing machine i0. 7 The housing l3 encloses a drive shaft 14 con nected in any suitable manner with the mecha-' nism utilized to operate the washing machine. 25 The upper end of the housing I3 is of sufficient . thickness to accommodate sockets l5 which may , be arranged in a circle 90 degrees apart. A fur ther socket I6‘ is located midway‘ between“ one pair of sockets I5. These sockets. constitute a part of the indexing mechanism hereinafter fully described. The housing 12 which encloses the wringer driving and indexing mechanisms is formed with a downwardly directed annular collar 20 adapted to ?t upon the upper end of the housing l3. Within the housing adjacent the collar 20 is a web portion 21 providing a bearing 22 in which ashaft 24 is mounted. The lower end of the shaft 24 is connected with drive shaft I4. The upper'end of the shaft 24 is ?tted with a pinion gear 25 which projects upwardly into a compart ment 26 of the housing l2. Projecting inwardly from the end wall 21 of the housing is a boss 29 ' in which an opening 30 is made. The boss 29 is opposite the open end of the housing and is Fig. 4, is an enlarged vertical sectional view . adapted to receive and support one end of a re-, showing an interlock between the reversing drive verse gear shaft 3 I . The top wall 33 of the hous 50 and indexing mechanism, being taken substan tially on the line 4—4 of Fig. .3; Fig; 5 is a. fragmentary vertical sectional view similar to Fig. 4,- showing the indexing mecha nism locked and the drive head in position for, use; ing is formed with an inwardly directed rein‘ forced portion 34 through which an opening ‘35 is made connecting the interior with the exterior of the housing. Adjacent to and formed integral with portion 34 is a vertical wall 36. .An opening 31 is made in this wall,'said opening being on‘ so as 2 2,116,695 center with‘ the opening 39.01"? boss 29. A cover plate 39 is adapted to close the opening 31. This dent that manipulation of the lever 55 will move the eccentrically mounted roller 68, block ‘II and cover plate is annular and abuts an annular gear 5| from neutral position shown in Figure shoulder 49 provided therefor in the wall 36.

The plate 39 is formed with a plurality of arms One of the side walls 69~ of the housing. l2, 4| having suitable openings to receive screws 42 I commencing adjacent the lower end of collar 20. which have threaded engagement with the wall 36 and serve to secure the plate in place. Cen trally of the plate 39 is an opening 44 which con 10 stitutes a further bearing for shaft 3|. The free end of shaft 3| is ?tted with a drive pin 45 with which a sleeve 46 is engaged. The other end of the sleeve 46 is slotted to engage a further pin 4'! of a wringer shaft 48. Provision of sleeve 46 15 makes possible convenient assembly and disas sembly of wringer and drive head. , and projecting upwardly to a point slightly be neath one of the ledges 10, is formed with an en larged portion 80 in which a cylindrical opening 8| is made. This opening commences at the lower 10 end of the collar 20 and projects to adjacent the upper end of the portion ‘89, continuing there through in a reduced diametered opening 82. Mounted in the opening 8| is an indexing pin 84. The lower end of this pin projects beneath the . collar 20 and is adaptedto register with one of That portion of the shaft 3| lying within the compartment 26 is ?tted with pins 49. -A twin gear 5| is mounted on the shaft 3| and includes‘ 20 opposed. sets of teeth 52, either set of which is engageable with the pinion gear 25. The opening in the gear 5| is formed with oppositely disposed key ways 53 into which the ends of pins 49 pro‘ ameter to form an extension 85 which projects. through the opening 82. Between the upper end of the opening 8| and the upper end of pin 84 is a spring 81, which normally exerts a pressure on pin v84 to move it downwardly out of opening ' ject. It is to be understood that the diameter of 25 the gear 5| is slightly less than the diameter of‘ ditions\ hereinafter fully described,v projectible the opening 31, thus permitting inserting this gear through said opening during assembly. Located on top of the housing l2 >is a revers ing lever 55. Within the opening 35 of the por 30 tion 34 is a shaft 56 from which projects a pin 51. The lever 55 is mounted upon and secured to this pin. Midway‘of the shaft 56 is an annular groove 59 in which at predetermined positions, depressions 60 are made. An opening 6| .is made 35 in portion 34. In this opening is a bullet nosed pin 62 which is normally engaged with they an nular groove 59 and one of the depressions 66, due to contact with a spring 64. Pressure of the spring 64 upon the pin 62 is varied by adjust- ~ 40 ment of a screw 65 which. is threaded into the ‘outer end of the opening 6|. In this connection it’ is to be understood that shaft 56 may be rotated byrotation of lever 55 and the bullet nosed pin 62 , will move out of a depression 60, but the enlarged 45 portion thereof will not move out of the groove the sockets |5 or I6 formed in the housing |3._ The upper end of the pin 84 is of reduced di 8|. The upper end of extension 85 is; under con 0f shifter block 1| or into the recess 15. I On that portion of the housing l2, heretofore designated as, collar 20, is, an indexing lever 90. This lever is mounted on a shaft 9| that extends 30 through collar 20 into portion 80, through a suit able opening 93. The shaft 9| is formed with a pair of slots 95 and 96. .The base wall of each slot is shown to be at a 45 degree angle to the center line of the’lever 99. A stop pin.9'| is 35 mounted in the collar 20 of the housing and pro jects through slot 95. Referring to Figure 10, it will be noted that the pin 91 limits the indexing lever 9ll-to a 90 degree turn, an edge of the slot striking the pin in either dotted or solid line posi tion of this ?gure. Slot 96 is of su?icient width to receive pin 84. The edge 99 of the base wall of this slot serves as a shoulder which engages the upper wall I00 of a slot |0| formed trans verely of pin 84. Rotation of the lever 90 from 45 59, thereby preventing inadvertent removal of shaft 56-from the housing | 2. Projecting down - a vertical to a horizontal position causes shoulder wardly from the lower end of shaft 56 is an off pin 84,- moving said pin upwardly‘a determined distance'against tension of spring 81. When the center pin 61, on which a roller 68 is mounted. 50' When the lever 55 is rotated in one direction to a point 90 degrees from the position shown in Fig ure 2 of the drawings, roller 68 'moves to the left. Conversely, when the lever 55 is moved in the op posite direction 90 degrees, roller 68 moves to ‘the right.‘ Reference is now had more particularly to fur~ ther interior structure of housing |2 (see Fig. 3), Between the top‘ wall 33 and web portion 2| of the housing and projecting inwardly. from each side wall 69 thereof is a ledge or shoulder 10. Mounted transversely of the housing with the ends resting-upon ledges ‘I9 is a shifter block 1|. 99 of shaft 9| to engage wall I90 of the indexing, lever 90 is in a' horizontal position, the lower end .60 of pin 84 has been withdrawn from one of the sockets | 5 or I6 in the housing l3, thus allow ing housing I2 and wringer -||ito swivel about ' shaft M to any desired position. Generally speaking, there are ?ve wringer positions, .one in which the wringer is-centeredover the top of the washing machine. ‘This position is obtained by 'locating the indexing pin 84 in socket 16. The other four sockets facilitate setting the .wringer in any one of four predetermined positions 90 degrees apart. ' i - ' a ' . This block (see Fig. 8) is a channel shaped mem her and comprises a base wall 12 and side walls ' 13. At one end the base wall is formed with a slot ‘I5. Adjacent the other end the wall 12 ‘is formed As mentioned above, the housing I2 is open opposite the end wall 21. The side walls 69 of the housing are shaped to fit the contour of the time board and clothes guide of the wringer | I so that when the wringer is engaged with the hous ‘ with an inwardly raised projection 16. One" edge ing the entirestructure will have a one piece ap 11 ofthe projection constitutes a stop to prevent movement of the roller 68 transversely of the 70 housing-I2 in one direction and full rotation of the reversing lever 55. . The shifter block, al though mounted on and movable along ledges 16, projects between the spaced sets of teeth 520! the twin gear 5|. Inasmuch as the gear 5| is mov 15 able axially of its supporting shaft 8| it is evi 25 either against the under face of the basewall ‘l2 ' pearance. Referring ‘particularly to Figure 2 it will be notedthat a‘ plate I63 is secured to'the end wall of the wringer | I. This plate is formed 70 with an opening I64, through which the wringer shaft 48 projects. The lower end of the plate is formed with a horizontal ?ange I95, the width of this ?ange being substantially that of the interior width of the housing l2. The upper end of plate - 2,110,665; ‘ 3 I88 is formed‘ with-an outwardly and upwardly upwardlytobecome disengaged from one of. the ' curved ?ange I01 which provides a pocket, I88. sockets IE or I6, if and when the shifter block ‘ Adjacent the upper wall 88 of the housing l2 and. ‘II is in neutral position.
