WRINGER.

Application filed December 15, 1927. Serial No. 240,089.

This invention relates to wringers, more particularly to power driven reversible wringers of the kind ordinarily associated with domestic washing machines.

In connection with such wringers I aim to facilitate rapid and successive feeding of pieces of material which are to be wrung without danger of the fingers or hands of operators being caught and mangled by the squeeze'rollers of the wringers. These ends I attain through provision of a very slmple and efficient feeding means which is absolutely positive in operation, capable of attachment to any standard form of wringer with capacity for transposal from one side to the other of the wringer, and embodying instrumentalities whereby the materials are first presented to the squeeze rollers, and thereafter advanced into the bight between said squeeze rollers for passage through the wringer.

In the drawings, Fig. I is a front view of a wringer conveniently embodying my invention.

Fig. II is an end elevation of the wringer viewed from the right ofFig. I.

Fig. III is a fragmentary end view on a somewhat larger scale than the preceding illustration.

Fig. IV is a partial cross section of the structure taken as indicated by the arrows IVIV in Fig. I.

Fig. V is a view similar to Fig. IV showing the manner in which the material is advanced between the squeeze rollers of the wringer; and

Fig. VI is a the important invention.

The wringer illustrated in Fig. I is, generally speaking, standard in construction. embodying a yoke-like frame 10 with suitable bearings in its vertical end portions to support the rubber-covered squeeze rollers 11, 12, and enclosing gearing to drive said rollers.

fragmentary view 'of one of details associated with my At opposite sides the wringer is equipped with sloping drain and guide chutes 13, 1 1, and between these is mounted an auxiliary drain plate 15 which is centrally pivoted at 16 so as to be tiltable for cooperation with either of the fixed drain chutes as required for forward and reverse operation of the wringer. A bracket partly shown at 17 in Fig. I serves, after the manner of a cantilever, to support the wringer horizontally over the top of the washing machine, said bracket being hollow for passage of the driving connections (not shown) to the squeeze rollers 11, 12. In standard wringers of the kind briefly described above, mecl'ianisn'i is also provided to enable reverse operation of the squeeze rollers, but since such mechanism is not Con cerned in the present improvements, a showing thereof has also been omitted from the drawings.

The feed means to which this invention is more particularly directed comprises a member 18 which is manually swingable upward from the substantially horizontal loading posit-ion of F III to the active or vertical position of Figs. II and'IV in presenting the material M to be wrung to the squeeze rollers 11, 12. As shown, the member 18 has the form of a hollow bar 19 with integral side arms 20 and manipulating handles 21. The arms 20 are notched as at 22 for engagement with fulcrum studs 23 on lugs 2e whereof there is a pair projecting outward from each side of the wringer frame 10 to enable transposal of the member 18 for use at either side of the squeeze rollers 11, 12. As convenient means for detachably securing the member 18, I provide keepers 25 that are defiectable about pivot screws 26 and have inward projections 27 (Fig. I) at their free ends to bridge the notches 22 in the arms '20 over the fulcrum studs 23. The keepers 25 are normally held by gravity in the closed position illustrated through contact of lugs 28 on them with stops 29 in the side arms 20. When the member 18 is to be removed for transfer, the keepers 25 are deflected upwardly about the screws 26 as far as permitted by engagement of lugs 30 with the opposite sides of the stops 29, the allotted movement being sufficientto clear the fulcrum studs 23 as will be obvious from the dot and dash line showing in Fig. III.

By reference to Figs. IV and V it will be noted that the rear portion of the cross bar of the member 18 is rounded as at 31 while its forward portion has the form of a tongue 32 with comparatively sharp frontal edge, Inward movement of the feed member 18 (toward the squeeze rollers 11, 12) is limited lilember is in, the active position shown in Fig IV, receives motion from the lower squeezefroller 12. By adjusting the sloping stops j 33 as above suggested it will be apparentfthat the proximity of the auxiliary feed roller relative to the lower squeeze roller 12,may [be regulated to a nicety in adapting the wringer for operation upon the thinnest materials without the tongue 32 ever actually contacting with said squeeze roller. It is tobe especially noted from Fig. IV, that the inner surface of the tongue 32 is rounded as at 41 into close conformity with the surface of the auxiliary feed roll 40/ This'construction insures the material M against injury by precludingthe possibility of its becoming wrapped around the auxiliary feed roll 40. Immediately below the roll 40, the member 18 is equipped with a supplemental tongue 42 which extends transwersel'y between the arms, 20 inparallelism with the cross bar'l9. The supplemental tongue assists "in retainment of 'the material bylthe bar 19 asthe member 18 is'swung into active position ashereinafter more fully explained. I v

tlloz prevent access of the fingers to the bigh-t betweenthe squeeze rollers '11, 12 incidentally to-manipulation of the feed member 18, I provide guard '43, which, in a general way, resembles the feed member 18 in that it comprises; a transversely extending bar 44 with-integrally formed side arms 45. Moreover, like the feed 'member 18, the

- guard 43 is transferable from one side to the therof- tl1e'squeeze rollers 11, 12 through provision of pierced ears 46 at opposite sides of the 'wringcr frame 10 to take pivot studs 47, 48 on said guard. Of these, the stud 48 lS'IGtlLCtZlbl to permit removal of the guard for the purpose mentioned. Beneath the cross bar 44 of the guard 43 :is .pivotally suspended an element 49 that has its lower edge chamfered and serves L0 check rearward slippage of thematerial on the feeding member 18 when the latter is in its active pos tion.

Y fIhe operation of. my invention is as follows: Assumlng the squeeze rollers 11, 12 to be rotating in the direction of the arrows (Figs.- I-II, IV) and the feed member '18 resting in the lowered horizontal position onth'e drainchute 1 3, the-leading margin of the material M is laid over thetongue 32 of said feed member as well as over the auxiliary feed roll 40 and the auxiliary tongue 42 after the manner shown in Fig. III. With this preparation, the ,member 18 is swung upwardly, through grasping of its handles 21, to the active position of Fig IV against the stops and the material thereby presented before the squeeze rollers 1 1, 12, the sharp edges of the tongues 32 and 4 2 acti;ng in concert to prevent the material from dropping off incidentally to such move- ;mentof the member 18. VVit-h passage of the crossbar 19 of themember 18 beneath the'guard 43, the element49 is swung inward. As shown in Fig. IV, the element 49 fiiially comes to'restat an inclination with its lower chamfered end resting upon that portion of the material which lies directly over the bar 19 of the member 18, the inclination being such as to .prevent rearward slippage of the material without'however interfering with its forward, progression. under draft of the squeeze rollers. While the material-is thus held in check, its lapping margin, caught between the lower squeeze roller 12 and the auxiliary feed roll 40,

urged upwardly and inwardly with attendantrolling'andadvancement of the-leading folded edge of the material into the bi 'ht between the two squeeze rollers.

b When once gripped by the squeeze rollers, the material is carried forward without further assistance from the feeding means so that the hold on ithe member 18 may be released until its aid is again required. Functioning of the various parts of my feeding mechanism incidentally to reverse operation of the wringer is precisely the same'asa'bove describechthe transposal ofthe member 18 and the finger guard 43 to'the opposite side of the wringer being so obvious from What has already been saidas to avoid necessity for repetitive description. V

It is tobe understood that my invention can be readily applied to existent wringers by separately attaching; the fulcrum lugs24 and the ears 46 instead of forming them integrally with the frame 10 as illustrated in the drawings. I

Having thus described my invention, I claim: 7
