geared relationship by means of pressure brought about by conventional wringer roll tensioning means the same being rendered ineffective' when the tensioning means is released.
A :further object is to provide a geared coupiing mechanism comprising a' driven'element and a co-operative element capable of being forced into or out of geared relationship therewith, the co-operative element being secured to a roll of the wringer whereby when pressure is brought to bear-upon the wringer roll, as when the wringer is adjusted to wring clothes, the cooperative element is forced into geared relationship with the driven element torotate the rolls, and when said pressure is released the co-operative element is made ineffective to maintain the drivingconnection.
An additional object is to provide coupling means between a wrlnger drive and rolls, which coupling is eilective to drive the rolls only when the rolls are in pressure relation, rotation of the rolls being automatically stopped when said pressure is removed.
Other objects will appear in the followin'gidescription and accompanying drawings in which;
Fig. 1 is a side elevational viewof a wringer embodying my invention, with a portion of the wringer frame broken away to permit clear view of underlying parts;
Fig. 2 is an end elevational view'oi the same taken from the right of Fig. 1;
Fig. 3 is a fragmental side elevational view of the right hand portion of Fig. l showing parts in operated position as will be described;
Fig. 4 is an approximately full size sectional elevational view ci m'y coupling mechanism to be described:
Fig. 5 is a sectional view taken from line 5-5 in Fig. 4 and FiFig. 6 is a plan view taken from line 6--6 in Fig. i discloses my invention embodied in a conventional roll wringer generally comprising a lower frame member i0 end frame members 'I I and I2, a releasable top frame memberl i3 c'arrying a spring il supported in the i'rarne vby means of an adjustment screw I5.
An upper roll I6 is iournalled in the frame in a conventional manner and spring I4 is effective to force' it downwardly upon the lower roll |1.
The left hand end of roll I'I' is conventionally .journalled in frame memberyil and the right hand is'supported in a special manner as follows:
i8l of the lower roll is fitted with a head member Fig. 4 illustrates that the end of drive shaft I9 secured to the shaft by means of a pin 20.
The head member is provided with indentations or recesses 2l as shown best'inFig. 5.
Indentations or recesses 2I` are adapted to be engaged by -a series of balls 22 retained in a collar member 23, by means of acage member 24. 'I'he cage is secured in the collar by means of rivets 25.
A. coupling Velement 26, adaptedto be connected i with the drivingmeans of the wringer, is secured in collar 23 and the collar is rotatablysupported in a bearing block 21 whereby the collar may be rotated continuously by the power source.
Dotted outline in Fig. 4 illustrates that the' relativediameters oi head. I9 and inner periphery of collar 23 are such that head I9 may be moved to a position substantially central of the collar to disable driving engagement between indentations or recesses 2l and balls 22. whereby the head may become a stationary member floating within the continuously rotating collar.
Fig.. 6 illustrates that frame Iiiv has inwardly directed edges I2' so proportioned as to conilne the head I9 against lateralmbvement. However. the head is vertically movablebetwe'en the edges. l
I that it is retained upon the end frame Il by means of a hook arrangement 2l which is thought v suiilciently well' known as to obvlate detailed description.
having a hook portion 30 adaptedto extend over the end of top frame i3 and a reversely fashioned lip 3i at its upper extremity.
Hooked with the lip 3i is a complementa] hook 5 32 of a lever 33. which is pivotally, supported at 36 upon'top :trame i3.
The lever has an extending vend 33' by means of vReferring to the top frame I3, it will be noted which it may manipulated to disengage hook I2 from lip ll.
It will benoted that with the parts in position shown in Fig. 1, the top frame is retained ulJOn the end frames whereby spring I4 may be tensioned by screw I 5 to force the upper roll I0 downwardly upon lower roll I1 which in turn forces the indentations or recesses of head member Il into driving engagement with balls 22 of the rotating collar 23. Obviously a geared couplingis thus formed between the driving-elea,s4e,4e4 u A the head member out'of aligned position are engaged whereby rotative movement of the driven member brings about similar movement of the wringer roll.
2. In a roll wringer mechanism having upper, lower and side frame members, a lower roll mounted by one oi its ends in a bearing in one ments and lower roll which is effective to rotate A side frame member, the roll driving member carried by the opposite side frame member, a driven member securedto said opposite .end o! said lower roll and loosely supported insaid driving member, an upper roll carried between said side frame members and cooperatively engageable with said lower roll, a pressure spring carried by said upper frame member and cooperative with said upper` roll for pressing the upper roll into engagement with the lower roll, means for releasing said spring pressure; and complemental insupport the geared relationship described, and
head I 9 is free to assume the central oating position described, into which position it would intermittently be forced by reasonvof balls 22 alternately engaging and escaping indentation 2i. the weight of the rolls not being sumcient to maintain driving relationship therebetween.
It is to be noted that any suitable gear devices may be used in place of the ball-.recess arrangement described.
With the foregoing in mind it will be apparent that a wringer embodying my invention has its usefulness and safety factor increased due 'ta immediate arrestment of rotation of the rolls upon release of the roll tensioning means.
What I claim is:
1. A wringer roll drive connecting mechanism comprising,'a recessed rotatively driven member, a head member secured to a wringer roll and rotatably disposed in said` recess, the interior surface of the recess and exterior surface of said head member being provided with complemental projections and recesses all so proportioned that when said head member is axially aligned with the driven member said projections and recesses are free of engagement, but upon movement ofv dentations and projections on the driving and driven members and co-active with one another to cause the driven member to be rotated by the driving member when the lower roll and its driven member are held downward by said spring pressure, said coactive indentations and projections being so conngurated that they are inoperative to eiiect rotation of said lower roll when said spring pressure ls released. l
3.'In awringer, a driven roll member and a driving memberthereior, one of said members equipped with a. hollow cylinder, inwardly pro' iecting rotatable devices mounted in and partially coniined in bearings formed in the inner iace of the circumferential wall of said cylinder, said devices being equally spaced from each other and from the axis of the cylinder. a shaft rigid with the other member and being of diameter to be rotatable relatively to said cylinder when disposed concentric with the latter, whereby to cause the roll member to remain normally idle, an idle roll associated with said driven roll, spring means manipulable to force said idle roll against said driven roll member to a position eccentric to the driving member, said shaft equipped with recesses in which said rotatable devicesl engage successively while said shaft is said eccentric position, thereby driving the lat'- NICHOLAS L'.
