Application filed March 14, 1925. Serial No. 15,434

This invention relates to improvements in the construction of Wringers of a type designed primarily for domestic laundry use, particularly in connection with Various types of washing machines. A general object of the invention is the provision of a wringer construction which may be manufactured economlcally, which will operate effectively for passage of ma terial through it-in either direction, which safe-guards both the material and the operator against injury, and which possesses many conveniences in demountability and accessibility of ,parts for cleaning or the like.

One of the particular objects'of the invention is the "provision of improved water guiding means effective to return expressed water toward the feed side of the machine and prevent its coming into contact with the portions of the material which have passed through the bite of the wringer rollers;

Another object of the inventionis the provision of a wringer unit comprising parts readily separable by simple lift actlon without the requirement of the release or detachment of bolts, screws and the like.

Another particular object is the provision of improved means of this sort which facilitates the feeding of the wringer at either side, and may be accommodated to either direction of feed with a minimum of adjustment.

Still 'another object is the provision of a construction which permits the complete disassembling of the Water directing members from the wringer frame quickly and Without the loosening of screws or similar connecting members.

Other and further objects will be pointed out hereinafter, indicated in the appended claims, or obvious to one skilled in the art upon an understanding of the present disclosure.

For the purpose of this application I,

have elected to illustrate and describe herein certain illustrative embodiments of the invention but it is to be understood that these are not to be presented as exhaustive of its structural forms, and they are not to be accorded any effect limiting the invention defined in the claims short of its true and most comprehensive scope in the art.

'In thedrawings forming a part of this specification Fig. l is a front elevation of the device, the upper portion being in section;

the shaft ofthe roller 22 is received slots of the side frame members so that 110 Fig. 2 is a sectional elevation on line 22 of Fig. 1 but with the upper portion of the wringer removed;

Fig. 3 is a top View trated in Fig. 2;

Fig. 4. is a section on substantially line H of Fig. 2'; Y

, Fig. 5 is a sectional elevation like Fig. 2, of a modified embodiment; and

Fig, 6 is an enlarged detail section showmg the drain deflector positioning means.

The nature of the invention will be most quickly understood by immediate reference to the drawings. Let it be understoodthat in these embodiments, there is a wringer of a portion illusframe made up of'a base channel portion 10 and end frame members 11, which latter are slotted at their inner sides so .as to procooperates at its ends with vertically slidableconnectors 16 which are positioned against the outer walls of the side frame members and retained by the headedrivets 17 which slide in slots 18,-one of the connectors 16 having an elongated slot 16 to accommodate the extended shaft end 13*. The connectors are slotted at their upperends and carry rollers 19. Stops 20 limit the downward movement of the connectors 16. The wringer head frame 20" is adapted to fit over the upper ends of the side frame members 11 and house the projecting portions of the connectors 16. The head carries the upper bearings 21v in which is journalled the pressure roller 22, same being held in\ the bearings by the pins 24. A stub shaft 25 is journalled at the top of the head 20 100 for rotation by means of the crank 26, and

carries at its lower end the toggle link 27. a

erallythrough the iheadmember and 105 through slots in the, bearings 21, in which said links are supported on rollers 29. When the head is positioned on the frame,

in the the pressure roller may contact the roller 13 and have the necessary freedom of vertical movement. Theconnecting links 28 align with the slots in the upper ends of the connectors 16 so that, upon rotation of the stub shaft 25, the connecting links will be moved outwardly and their bevelled outer ends projected under the. rollers 19. The wedging action thus exerted on the rollers 19 will cam the connectors 16 upwardly and stress the spring 15, the reaction of which is transmitted through the connectors and connecting links 28 to the upper bearings 21 and the pressure roller 22, so as to press the latter into cooperation with the roller 13 under yielding pressure. By rotation of i the shaft 25 the connecting links 28 may be retracted from engagement With the rollers 19, and the head thereby freed to permit its complete removal, together with the pressure roller 22, from the frame. The roller 13 likewise may be removed from the frame by lifting it through the side frame slots at such an inclinationthat the end of the shaft may be Withdrawn from the socket 14.

The means for controlling the direction of flow of the water from the wringer rollers includes an apron member and an adjustable flow directing member. As is best seen in Fig. 4, the terminal portions of the end frame members which overlap the base member 10, are flanged outwardly to provide the slot flanges 30 which constitute retaining members for holding the apron on the frame. The latter is formed of bracket portions 31 which have laterally directed flanges 32 adapted to be received under the slot flanges 30. These bracket members are connected by andsupport the sloping apron 34, which is turned up at its ends to provide the flow guides 35, which extend to the side frame members. The bracket members 31 may be made of quite stiff metal and shaped to embrace the flow guides 35, and afford substantial supports for the relatively light apron portion 34. The brackets 31 at the opposite sides of the base member are connected by stiff straps 36 which are humped upwardly to fit over stop members 37 struck upwardly in the top of the base frame member. Consequently, the entire apron may be removed from the frame simply by sliding it upwardly until the flanges 32- are disengaged from the flanges 30. It will be observed that portion 34 extends up to a position overlapping the base member 10, and its slope is such as to carry away water which may be discharged onto it at either side of the rollers.

The flow directing member is in the nature of a tilting drain board having a slightly concaved base portion 40 extending substantially the full width of the opening between the side frame members 11. This is carried on bifurcated end plates 41 which have their outer margins deflected inwardly to form guards'42, same being of sufficient width to overlap the end portions of the rollers. Adjacent. their upper extremities the end plates 41 are provided with outwardly deflected hooks 44 adapted to be slid onto the end frame flanges 11 at the top of the latter, and being so spaced as plates on said flanges without 'the possibility of disengagement. By virture of this arrangement the flow direct-ing member 40 may be adjusted either to the position illustrated in full lines in Fig. 2, or to the position illustrated in dotted lines. In the first mentioned position it'will deflect water discharged from the rollers to the right, and discharge it. on the apron member 34, and when in the other position the drain board will direct and discharge the waterto the left. To retain the flow directing member in the selected position, it is provided with the lugs 45, carried on the end plates 41, adapted to ride over, as the flow direct-ing member is swung in either direction, the up-struck portion of the connecting straps 36 and be held against movement in the reverse direction by the engagement of said lugs with said Lip-struck portion. In order to adjust the drain board from one position to the other, therefore, it is necessarythat it be lifted slightly, as permitted by the freedom of the hooks 44 on the flanges 11 so that the lugs 45 will clear the stops, and then swung to the opposite position and again lowered so that the lugs will contact the stops. It will be observed that the upri ht end portions of this flow directing mem er overlap the ends of the rollers, so that water flowing off of the latter will be caught and discharged in the desired direction. The guards 42, in their overlapping relationship with the ends of the'rollers, prevent the material fed between the latter from working off the ends of the rollers and becoming wedged or entangled between them and the side frame portions. One of the great advantages of this construction and arrangement of the adjustable. .water directing member resides in the fact that it may be relatively narrow, whereby its higher side is maintained substantially below the bite of the rollers and out of the path of the material issuing therefrom, while its lower side is in contact with the apron portion 34 and does not offer opportunity for material becoming caught between them whenfed into the machine. The head of the machine and the", rollers having been removed as "above described, the adjustable water directing member may be completely removed from the frame simply by sliding it upwardly on the flanges 11 following which the entire apron may be removed as above described;

to permit a rocklng movement of the end In; the construction illustrated in Fig. 5 the apron portions 34 at the opposite sides of the frame 'are independently removable, being carried on brackets 31 which are retained by slot flanges as in the form de-' scribed above. In this embodiment the Water .directing member 50 has trunnions 51 which arejournalled in holes in the lower bearing members 12, and it is frictionally retained by ,an expansion spring 52 coiled on the trunnions. An end guard 54:. is mounted on each of the side frame members, being retained by outwardly turned flanges 54* which engage on the end frame flanges 11 Each end guard has an arcuate inwardly directed flange 54 which underlies the ends of the rollers to catch water therefrom and direct it on to the member 50. 'At their outer sides the end guards have inwardly extending guard flanges 54 which overlap the ends of the rollers to prevent material feeding .ofl" of them, The. end guard members 54 are connected by troughlike guides 55 which are hinged on ears 54?. These guides support the material as it is fed between the rollers and as it issues from them, preventing its coming into contact with the adjustable member 50. This arrangement of end guards is effective to prevent water flowing down along the end frames and flowing off at the discharge side of the machine. i The end guard members 54 and their connectingguides are completely removable from the frame, as a unit, after the head and rollers have been removed, by sliding them upwardly to disengage their flanges 54 The adjustable member 50 is likewise removable from the frame by sliding the bearings .14 upwardly through the end frame members, and the aprons are likewise removable from the frame by slidingthem upwardly out of the flange grooves.

From the foregoing, it will be noted that the invention generally involves details of structure that serve for convenience and higher utilities. Especially is this true with reference to the denrountable features which make it possible, by the removal of the top framing member, which. removal carries with it the top roll that the lower roll may then be lifted out and thereafter successively the deflector drain member and apron,or aprons.

Further, in actual conception I have in mind, and have in practice, associated the two flow guides in a single unit and removably mounted it at the top of the base member of the frame immediately below the adjustable drain member.

The main feature of the invention resides inthe capability of ready separation of all of the parts of the complete wringer unit without utilizing screws, bolts and the like.

In addition to the features of advantage above suggested is that of being able to disassociate related parts for convenience in shipping.
