WRINGER' RELEASE MECHANISM Carl Moon, Detroit, Mich. I Application June 18, 1934, Serial No. 731,075

This invention has reference to wringer roll mechanism, particularly to release mechanism therefor, and has for one of its objects-provision of a release mechanism capable of being operated by means of an unusual movement of one or both.

of the wringer rolls relative to each other and the wringer frame. A further object is to provide means for re.- taining the upper wringer frame portion upon the lower portion, the retaining 'means" being quickly movable out of retaining. position by means of off-setting movement of the roll.

Other objects will apppear in the following description and accompanying drawing in which Fig. 1 is a side elevational view showing an embodiment of my invention with certain .por-' tions broken away to facilitate deposition;

Fig. 2 is afragmentary detailed view showing movements of a portion of my mechanism to be described.

Fig. 3 is a fragmental View showing detail of structure and operation of a portion of the mechanism shown in Fig. 4.

25 Fig. 4 is a fragmental outline prospective detail view of a portion of the mechanism to be described.

Fig. 5 is a prospective View showing the parts included in Fig. 4 in dis-assembled position and 30 Fig. 6 is a sectional View taken from line 6-6 on Fig. 1.

Fig. l discloses my invention in combination with a roll wringer mechanism which generally comprises a conventional wringer post designated l0, carrying a driving shaft H, gears I2 and a driven gear l3.

A lower wringer frame I4 is supported upon the post and is fitted with a removable top frame member l5.

40 The upright end portions of the lower frame are preferably of hollow construction of a form designated 16 in Fig. 6.

A lower wringer roll I1 is mounted in the frame by means of its shaft l8 journalled in the lower 45 ends of member l9 which are pivotally supported on frame M by means of studs 20.

Shaft l8 has driving connection with gear l3 through a flexible coupling 2|. The opening in frame I4 through which shaft l8 passes is of 50 such proportions as to permit the shaft to move relative to the frame and the flexible coupling noted permits such movement without alteration of the driving connection.

The upper ends of member I9 are fashioned 55 to have outwardly directed hooks 22 and engaging these are inwardly directed hooks 23 formed on the inner end portions of top frame [5. The function of this will be explained shortly.

An upper wringer roll 24 is journalled in mem 5 bers 25 which are pivotally mounted at 25' upon angulated plate members 26 which have upper horizontal portions 21. Fig. 6 will illustrate that members 26 are so proportioned as to slide vertically within the uprights of frame 14. 10

A spring member 28 is mounted in the top frame by means of an adjustment screw 29 and has its outer ends resting upon plates 26. The spring is obviously adapted to force the-plates, carrying members 25 and roll 24, downwardlyi 15 to abut lower roll ll. However the spring is not effective except when the top frame is re- 1 tained in suitable position upon the lower frame which arrangement is accomplished by reason of hooks 22 being engaged with hooks 23 of the top frame.

It will be noted, as best shown in Figs. 4 and 5, that member l9 carries a boss 30 which engages a slot 3| formed in the adjacent side of member 25.

It will also be noted that roll I! may be swung laterally about the axis of stud 20 and roll 24 about the axis of pivot 25' and that the members are made to operate in unison by reason of stud being engaged in slot 3|. 30

Fig. 2 illustrates the possible movement of member I9, and Fig. 3 illustrates, in solid lines, the relative position of

hooks

22 and 23 when the roll is in normal central position. In this position hooks 22 are obviously adapted to retain 5 the top frame in position to hold spring 28 in pressure relation. Swinging movement of the lower roll will displace the hooks as shown in dotted lines, whereby the top frame and pressure 40 will be released.

With the foregoing in mind it will be clear that with parts arranged as in Figs. 1 and 4 the wringer may be operated in conventional manner. If, during this operation the rolls are pushed or pulled out of vertical alignment members l9 and 25 are swung upon their pivots as indicated in Fig. 2 which movement will obviously displace hooks 22, as noted, to release the top frame.

The action described has special utility in the event of accidental insertion of an operators fingers between the rolls. In such an event an operator would involuntarily jerk or pull away from the mechanism and this movement would result in immediate releasement of pressure between the rolls as above described.

While I have here shown an embodiment of my invention, numerous modifications of its structure will be apparent to those skilled in the art. I do not wish to be limited in the matter of structure except within the scope of appended claims.

What I claim is:

1. A roll wringer mechanism having in combination a lower frame, a top frame, upper and lower wrin ger rolls supported in'a manner to be laterally movable with respect to the frames, mechanism connecting the roll supports whereby the rolls are caused to move in unitary direction, tensioning means adapted,to maintain the;

rolls in pressure relation, mechanism connected with the rolls for retaining the same in pressure relation, said mechanism being movable,vupo n lateral movement of the rolls, to release the tensioning means.

; 2. A- roll wringer mechanism having in come binationa lower frame, a movable top frame, u per and lower =vvringer rolls laterally movable in the lower frame, tensioning means active to forcethe upper roll into pressure relation with the lower roll, mechanism connected with the lower roll for retaining'the tensioning means active, said mechanism being mo vable, upon lateral movement of the lower roll, to release the tensioning means, i e r ;-3, In; a roll wringer mechanism the combination of a lower frame, a top frame releasably attached thereto upper and lower wri'nger rolls pivotally mounted in the lower frame and mech:

anism connecting the rolls and top frame wherer,

by lateral movement of the rolls in the,f1"2ir'ne brings about releasement of the top frame from the lower frame. g

4. A roll wringer mechanism having in com: bination a lower frame, a removable top frame,

upper and lower wringer rolls, said rolls being supported by means of mechanisms pivotally supported in the lower frame whereby the rolls are laterally movable with respect to the frame, said mechanisms having connections with the top frame whereby when the rolls are in one position the top frame is retained upon the lower frame and when the rolls are moved laterally from said position the top frame is released from the lower. frame a 5 A roll wringer mechanism having in combination a'lower frame, a removabletop frame, u per and lower wringer rolls, said lower roll being supported by means of mechanisms pivotally supported in the lower frame whereby the roll is laterally movable with respect to the frame, saldmechanism having connection with the top framewhereby when the roll is in one position the top frame is retained upon the lower frame and when the roll is moved laterally from said position the top frame is released from the lower frame.'

v 6. Air'ol l wr'iiiger mechanism having in combinationra' lower frame, a movable top frame,

said members having, portions supporting the lower roll in laterally movable relation to the lower frame whereby, lateral movement of ,the roll brings about movement of said hooks in position to retain or release the top frame.
