4 Claims.

Wringers, as made, commonly involve a frame, ordinarily of sheet metal, which is made up of a base, side stiles and top bar. The wringer rolls are commonly mounted in bearings carried by the side stiles. Most Wringers as now made are applied to washing machines and are driven from a gear mechanism arranged at the end of the wringer. In forming the wringer so that it may correspond in appearance and with proper symmetry with the wringer parts, gear and washing machine, it has become desirable to provide build-up covers for the operating stilcs so that the appearance of the wringer may be specialized and given a more pleasing appearance, particularly with relation to the washing machine or parts to which it is attached. In this way the standard stile or frame may be used, and varying forms of build-up covering applied or incorporated so that the wringer as a whole may be given the desired appearance without interfering with the functional features necessary for the operation of the wringer. In the present invention this is simply accomplished. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows:

Fig. 1 shows a plan view of a wringer partly broken away to better show construction.

Fig. 2 a front elevation of the wringer, parts being broken away to better show construction.

Fig. 11 a front elevation of a further modification.

Fig. 12 an end view of the same modification.

Fig. 13 a section on the line l3l3 in Fig. 12.

In the modification shown in Figs. 1 to 6, I marks a base of the frame, 2 and 3 side stiles on said base. 6 marks a lower roll, 5 an upper roll. The lower roll has a shaft 6 operating in bearings l. The bearings i are mounted in the side stiles. The upper roll has a shaft 8 operating in bearing 9, slidingly mounted in the side stiles. A

stile 3 by pin l9.

securing pad I0 is secured to the end face of the side stile 2 to facilitate the attachment of the wringer to a support, usually the gear case. A spring H operates on the upper bearings 9. It is arranged in the top bar l2 and is adjusted by a screw it operating in a nut M mounted in the top bar. These parts are, or may be, of common construction and may be conveniently made of stabbings.

One end of the top bar is connected to the side stile 3 by a resetting device. This resetting device, as shown, is in the form of a toggle lever which includes a lever l5, hinged at IS on the top bar. The lever 15 is connected by a link I! with the side stile 3. The link I! is pivotally connected with the lever i5 by screws [8 and with the The lever I5 is of channel form, forming a face plate 20 at the end of the wringer and sides 2! which, when the resetting lever is in set position, are opposite the front and rear faces of the stile 3. These side plates 2i of the lever l5 may be spaced from the side stile 3 to any extent desired to give the apparent dimension to the side stile desired. In other words, the setting device may in itself be utilized as a build-up covering for the side stile. The link I1 is also of channel form having the two sides through which the pivot members pass and .a connecting plate 22. The sides of the link when the lever is in set position are between the sides 2| and the side stile 3.

The side stile 2 is provided with notches 2211 at its inner corners near the top forming shoulders 23 which are adapted to engage hooks 24 of a latch 25. The latch 25 is of channel form providing a hook 224 for each shoulder 23. The sides of the latch are connected by plate 26 from which extends a trip finger 21. The latch sides are provided With pivot slots 28 and a pivot pin extends through the sides of the top bar and through the slots 28 thus forming a pivotal mounting for the latch permitting end-wise movement of the latch. A trip plate 3! has the pintles 32 arranged at its ends. These pintles extend through cross plates 33 which are secured in the wringer top and provide a pivotal mounting for the plate 31. The trip plate is provided with slots or openings 3-l near each end. Sliding cross members 35 extend through slots 31 in the sides of the top bar. These cross members have openings 35a into which projections 36 extend. The projections 36 are formed on the walls of the slot 34. Operating bars 38 are secured to sliding cross-members 35. By operating the cross members the plate 31 may be rocked for opcrating the release. The end of the plate has a trip projection 3; which is adapted to engage the trip finger 2'! and holds the latch in set position with the hooks 24 in engagement with the shoulders formed by the notches 2211. A spring 39 is secured to the latch and to one of the cross members 33 and tends to draw the latch to the left so as to hold the trip finger 21 under the trip projection 3|a. When the release device is operating by actuating one of the operating bars 38 the projection 3la is moved over the finger 21 and the pressure of the spring I l on the hooks 24 swings the latch 25 upwardly releasing the hooks and releasing the top bar. the resetting of the latch mechanism may be accomplished the hooks 24 have the cam surfaces 39a on their under sides which, as the top is forced downwardly, engage the tops of the wringer and swing the hooks so as to clear the face of the stile. As the hooks reach the notches 22a, extensions on the slotted ends of the latch engage the top bar and with the further downward movement of the top bar and inner end of the latch is forced downwardly. As the finger 27 engages the upper side of the projection 3la, which is inclined, the latch is forced toward the right sufliciently to snap under the projection 31a. The spring 39 then forces the latch outwardly to bring the finger 21 under the projection 31a thus completing the resetting of the release mechanism. After the release mechanism is reset, a resetting mechanism formed by the toggle levers at the opposite end is forced down setting the pressure on the wringer.

This specific release device forms no part of the present invention and in general follows the release mechanism of application #670,461 filed by me May 11, 1933, since matured into Patent No. 2,087,977 dated July 27, 1934.

The build-up covering for stile 2 to make it conform with the reset end and to give it the appearance desired comprises the following members: The stile as formed is rectangular in cross- In order that section, the inner wall of the stile being slotted at 40 to receive the roll shafts. The front and rear faces of the stile have detents 4|. Build-up covering strips 52 are arranged on the front and rear faces of the stile. These are of channel form with inturned flanges which seat against the faces of the stile. The outer walls of the covering member have perforated detents 44, the detents receiving the heads of screws which extend through the covering strip and perforations 46 into detents 41 of the side stile. 41 are arranged in the detents 4| and the screw thus provides a means for definitely securing this built-up covering to the faces of the stiles. This permits of providing the stile with a large variety of build-up parts that may change the entire appearance and make the wringer as a whole conform to its surroundings. Preferably the buildup member is extended upwardly along the front and rear faces of the topbar and not only makes Nuts it possible to close and make a better appearthe usual form, these roll guards having inturned flanges 49 so that the guards may be attached to the'side stiles. These inturned flanges engage the walls of the side stile along the edges of the slots 40.

A water board 50 is provided for the wringer. This is preferably of stabbed metal with sides 5! which extend upwardly at the ends of the rolls and the faces of these sides engage the faces of the side stiles of the wringer and supplement the build-up covering of the stiles. The sides of the water board have the out-turned flanges 52 which may he slipped into position on the edges of the roll guards as clearly shown in Figs. 5 and 6, thus assembling the water-boards on the wringer faces.

' In the modification shown in Figs. 7 to 10 the wringer frame, top bar, rolls, bearings, pressure device, release mechanism, are similar to that in the modification of Figs. 1 to 6. This modification differs from the structure shown in Figs. 1 to 6 in that the reset lever I5 is omitted and a build-up covering 42a corresponding exactly with the build-up covering 42 of the mod fications Figs. 1 to 6 is used in connection with that buildup covering. The wringer is provided with a water board corresponding to the water-board of the first modification. The side stile at the opposite end from the release mechanism has a stabbing forming a shoulder 54. This engages a shoulder 55 on the top bar, which shoulder is iormed by a stabbing 56. In this way the end of the top bar opposite the release may be engaged and the pressure screw l3 may be used for resetting the pressure on the wringer rolls.

In the modification shown in Figs. 11 to 13 a frame and wringer parts similar to those in the modification Figs. 1 to 6 are used. Build-up coverings 58 for the stiles are formed, integrally with a water-board 59, the sides of the waterboard and on the inner edges of the build-up portion being provided with flanges 6B which slide down inside the roll guards 48 for securing the water-board and stile build-up covers in place. As shown, these build-up covers form skirts, making the stile a much greater breadth from front to rear at the bottom than at the top. The structure involves a reset lever 15 hinged on the top bar as in the first modification but of a shallower channel design closing on the outer faces of the build-up covers for the side stiles, thus supplementing these build-up portions in forming the completed build-up for one of the stiles. The lower end of the lever 15 is curved inwardly at El so as to conform to the general shape or design of the wringer. The wringer is provided with a support at 51.

What I claim as new is:

1. In a wringer, the combination of a frame comprising a base and side stiles; rolls mounted in the stiles; pressure devices for the rolls; and build-up housings for the front and rear faces of the stiles changing their proportion in size to the wringer, said build-up housings including a water hoard between them.

2. In a wringer, the combination of a frame comprising a base and side stiles; rolls mounted in the stiles; pressure devices for the rolls; buildup housings for the front and rear faces of the stiles changing their proportion in size to the wringer; and a water-board having sides sup plementing the build-up housing of the stiles.

3. In a wringer, the combination of a frame, comprising a base and side stiles; rolls mounted in the stiles; pressure devices for the rolls; a releasable top bar receiving pressure from the pressure device; and a build-up housing for the front and rear faces of a stile changing its proportion in size to the wringer, said build-up housing extending upwardly from the stile along the outer faces of the cross bar, the extension forming a guide assisting in the assembling of the top bar, and. said build-up housings including a Waterboard between them.

4. In a wringer, the combination of a frame, comprising a base and side stiles; rolls mounted in the stiles; pressure devices for the rolls; a releasable top bar receiving pressure from the pressure device; and build-up housings for the front and rear faces of the stiles changing their proportions in size to the wringer, said build-up housings extending upwardly from the stiles along the outer faces of the cross-bar, the extension forming a guide assisting in the assembling of the top bar.
