7 Claims.

This invention relates to improvements in wringers, more particularly of the type shown in United States Letters Patent Nos. 1,902,580, 1,906,406 and 1,906,407.

The principal objects of the invention are directed to improvements in wringers of the type shown in the patents referred to wherein means is provided to guard against clothes being wound around a wringer roll and novel means is provided which is adapted to serve as a drain-board while the wringer is in operation andto conceal the rolls when the wringer is not in operation, thereby to provide a pleasing appearance as well as to protect the rolls.

Various other novel features and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the present preferred form of the invention, reference being had to the accompanying drawings wherein: I

Figs. 10 and 11 are sectional views on the line l0l 0 of Fig. 1 with the parts shown in different positions; and

Fig. 12 is a perspective view of a yoke member.

Referring now to the drawings more in detail the invention will be fully described.

The novel features of the invention are adapted for broad application but are particularly adapted for use in connection with a wringer for a washing machine where material is received by the wringer from a washing "machine tub. The head of the wringer is represented by l and may include a frame or housing and a column 2 as shown which is arranged for mounting on the upper side of the usual column of a washing machine. The usual wringer driving element or pinion which is driven by the washing machine mechanism is represented by" 4.

The frame 6 associated with the head has a hub 8 in which is rotatable a driven shaft Ill. The inner end l2 of the said shaft I0 is rotatable in a hub part [4 at the forward end of the head frame whichis hollowed out to receive an end portion I6 of a shaft l8 of a lower drive roll 20. A pin 2| of shaft part I6 is received in a slot of the end l2 .of shaft I0 whereby the shafts are operatively connected. I,

A shiftable member 22 has an end bearing 24 which is slidable and oscillatable on the bearing 8 of frame 6. A forward portion 26 of member 22 is oscillatable and slidable on shaft ID. This member 22 by being reciprocable back and forth on shaft l0 moves gears 28 on shaft [0 back and forth to bring them into and out of mesh with the pinion 4. A key or keys 21 associated with one gear 25 and shaft l0 permits the gears to slide on the shaft but serves for driving the gears from the shaft, the said gears being connected to a tubular member 29 as by welding so that they move simultaneously.

A stud member 30 associated with frame 6 has a lower end 32 in engagement with an angularlydisposed slot 34 of member 22 as shown in Figs. 1 and 7. This is so that as the member 22 is oscilla$ed relative to shaft II) it will be reciprocated to move the gears 28 relative to pinion 4.

A yoke member 40 is oscillatable on the hub portion l4 of the head and is provided with a slot 42 in its upper side as shown in Fig. 12. A lug 23 of member 22 carries a roll 44 which extends through an opening I at the inner side of frame 6 (see Fig. 4). This roll 44 is disposed between ribs 46 associated with the yoke 40 at its rear side. As the yoke 40 is oscillated, the member 22 is oscillated thereby and simultaneously moved back and forth to bring the gears 28 into and out of engagement with the pinion 4.

A receiver 50 is slidable up and down in th head which has a vertically extending slot 52 on the inner face thereof as shown in Figs. 4, 6 and 9. The saidslot 52 is widened out below its upper end as at 54 and rolls 56 in slots such as' 51 are pivoted at 58:50 theiradjacent peripheries extend inwardly from the sides of the slot 54. Projections 60 also extend from the sides -of the slot 54 as shown. A cap 62 is pivoted at 64 to the receiver and is arranged so that it overlies slot 52 and may swing upwardly from the position shown in Fig. 6 from off the upper end of the slot 52 to the position shown in Fig. 4.

There is an ear such as 66 on either side of the receiver, as shown in Figs. 4 and 9, and webs 9 extend across the frame 6. Bolts such as 68 are associated with the ears of the receiver and are slidably mounted in the web 9.

A spring I is provided around each bolt to urge the receiver downwardly. Longitudinal side webs 80 extend from the frame 6, and are connected to an outer end frame 82. The frame 0, webs 80 and outer frame 82 constitute a wringer frame or support. The outer frame 82 has a receiver slidably mounted therein similarly to that described in connection with the head end of the wringer and a cap 62 is provided on the receiver associated with frame 82. The receivers receive opposite ends of an upper roll-guard or separate frame assembly unit G after the manner disclosed in the above-mentioned patents. It will be understood that the receiver associated with frame 82 moves up and down as does the receiver inframe 6 and, being similarly mounted, they are both urged downwardly by springs. 1

The outer end I I of shaft I8 of lower roll 2 is journalled for rotation in the outer end frame 82 as shown in Fig. 1.

The roll-guard assembly is indicated by G and includes a manually engageable longitudinally extending frame guard bar 90 which h'as lugs such as 92 depending from opposite ends thereof (see Fig. 1). Hubs 94 are associated with the lugs 92 and an upper roll 96 and shaft 98 are associated with the hubs so that the said roll is freely rotatable relative to the guard bar. Projections such as 98 extending outwardly are associated with the hubs 94 at opposite ends of the frame or guard.

The frame or guard unit may be inserted within the wringer or withdrawn therefrom. As it is inserted in the wringer the hub 94 at the head end of the frame enters the slot 42 of yoke 40 while the projections 98 at opposite sides enter the slots 52 of the receivers associated with the frame 6 and frame member 82. As the roll frame or guard is inserted in the wringer, the yoke 40 is in a neutral position, with the slot uppermost to receive hub 94. When the roll guard has been inserted in the receiver slots with roll 96 resting 'to oscillate member 22 and cause one of the gears to engage with the pinion 4. The frame unit is shown in one operative position in Figs. 6 and 11. In such a position as shown in Fig. 6 the projections 60 lie under rolls 56 while the hubs 94 lie under projections 60 of the receivers. With the upper roll resting on the lower roll the frame is releasably locked to the wringer. As material is passed through the rolls the upper one is elevated and it elevates the receivers which are spring pressed downwardly. In this way the upper roll is under the influence of springs III.

Depending upon the direction in which the frame 90 is swung to an operative position, the rolls 20 and 96 will be driven in one direction or the other. It is desired, however, that the rolls be so driven that the leading-in side thereof is at the side of the wringer on which the guard is located when in operative position.

In Figs. 6 and 11 the leading-in side would be the left-hand side, the frame or guard being located on that side of the wringer. The general construction of the wringer thus far described and its mode of operation is similar to that disclosed in the patents above referred to and need not be described herein more in detail.

Guard plates I00 extend along the bar 90 and carry hubs IOI on their opposite ends which are pivoted as on a rod or rods such as I02 which is associated with the bar 90. As shown in Fig. 2,

' a spring I04 has its opposite ends in engagement with the hubs IOI of the members 100. This is arranged to cause the plates to swing downwardly and inwardly so that their lower ends will yieldingly bear along the sides of the upper roll 96.

Longitudinally extending cover and drain plates IIO are pivoted at I I2 adjacent their lower sides and opposite ends to inner sides of the frame 6 and frame member 82 so that they may swing between the positions shown in Figs. 10 and 11. In their upper position such as shown in Fig. 10 they overlie the sides of the rolls 20 and 95 and the longitudinal lower edges of the guard plates I00 overlie their upper edges as shown to hold them in position.

When the members IIO are in their upper position shown in Fig. 10, they'conceal the rolls from end to end of the wringer and not only protect the rolls but present a pleasing appearance. When in their lower position such as shown in Figs. 4 and 11, they serve as drain boards. When the wringer is to be operated, the members H0 are released by swinging the members I00 upwardly so that said members I I0 may swing to'their lower position.

Locks I20, more clearly shown in Figs. 6 and 8, are pivoted as at I22 to ears I23 of the frame 6 and have finger engaging portions I24 which extend downwardly below the frame. Projecting parts I29 extend forwardly from the frame through slots I21 engage upstanding flanges III of the members I I0 to lock the members H0 in the inclined position shown in Figs. 6 and 11. When the locks release the members IIO, they may be swung to their upper position shown in Fig. 10. q

A drip board I30 is pivoted at its opposite ends to frame 9 and outer end frame 82 as by stud such as I32 for tilting movements. An ear I34 carried by the yoke 40 co-operates with a curved seat I36 on the end of the drip board so that as the yoke is oscillated between inoperative and operative positions the drip board is tilted from a horizontal position or returned from a tilted position to the horizontal position shown in Fig. .11. When the member 90 is tilted to the left, as shown in Fig. 11, the board I30 is tilted so that water dripping from the rolls or from the clothes being passed therethrough is directed by the member I30 onto one of the men ipers H0. In this way water is directed back into the tub from which the clothes have bee withdrawn.

The members I I0 not only function as covers 'for concealing and protecting the rolls but also as drain members for the wringer. As an important feature of the invention, means is provided which tends to return the yoke to neutral position when the upper roll guard unit is unlocked from the receivers. To accomplish this detents, such as I40, are slidable in the opposite sides of yoke {40 (see Fig. 6) which are spring pressed outwardly by means of springs such as I42. The lower ends of the detents, when the yoke is in neutral and inoperative positions, yieldingly bear on the upper edges of the connecting plate members 80. When the yoke is swung to either of its operating positions, the detent at the side thereof away from the leadingin side of the rolls tends to return the yoke to neutral position. Then, when the roll unit is released, the detent returns the yoke to its neutral inoperative position.

While I have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto since many' changes and modifications may be made therein without departing from the spirit and scope of the invention.
