To all whom t may concern:

Be it known that ll, ROLF SELQUIST, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny e and State of Pennsylvania, have invented -a new and useful improvement in Wringers,

of which the followingfis a specification.

This invention relates to wringers and particularly to that type used in connection 1.0 with and mounted upon washing machines for wringing the clothes after the same have been washed. U

llt is the object of this invention to provide means to prevent further turning of the l wringing rollers after the same have been cholreclfby an abnormal accumulation or a bunching of articles passing between the same, or in the event that the articles be fed into the wringer at a rate abovethat for 29 which the wringer is designed.

llt is a further object to relieve the load upon thel driving motor in the event ofy choking of the rolls, thus eliminating the danger of burningout the motor when an 95 electric motor is employed. y

Special objects of the invention are to provide a construction in which the mechanism for accomplishing the above mentioned objects is readily responsive regardless of the point alongthe rolls at which the choliing occurs or at which the operator may be caught, which will be simple andV easy `to repair, which` will be Ladapted for use in conjunction with various forms of well known release mechanisms for relieving the tension upon the rolls, and which may be adjusted to function under varying conditions by varying the tension of kthe ordinary tension means for the rolls. 1

Like reference characters denote corresponding elements throughout the several views of the drawings in which Fig. 1 is a vertical sectional view with parts in elevation of the preferred embodiment of my invention; and Fig. 2 is a transverse vertical sectional view taken on the line lll- H of Fia V1- #The preferred form embodying the invention `comprises a main frame'or housin 1 provided with the compartments 2 an 3 formed by the inwardly extending ribs 4 and 5 upon the interior of the housing. Extending substantially the full width of the housingv are the wringerrolls 6 and 7, the upper roll 6 having extensions 8 and8 pro- ,bolt 16 and the extension 9 is similarly posiseriai no. 483,397.

' jecting into the compartments 2 and 3 and the lower roll 7 being similarly provided with extensions 9 and 9. Mounted upon the extensions 8 and9 are the fixed pinions 10 and 11. .The extension 9 is journalled in a recess 12 in the driving gear 13 and its shaft 13.", a bushing 14 being provided for lthis purpose. The shaft 13 rests upon the fixed bearing block 15 supported by the pin or tionedv by the bearing block 17 and pin 18. The extension 8 on the upper roller has attached thereto pinion 19 normally meshing with the drivinggear 13. Resting upon the extensions 8 and 8 are the Heating bearing blocks 20, 20 lsupported with coil springs 21, 21"', the 'tension of which may be adjusted by moving the cross bar 22 through the agency of the levers 23, 23', cross-head 24, stu'd'shaft 25, and the adjusting shaft 26.

A well known form of release mechanism is illustrated at 271-28 to relieve the pressure between the rolls when desired. rfhe details of the tension adjusting means and release mechanism form no part of the present invention andv need not be described in detail.

A strut rod 29 extends across the bottom of the housing which may be used as a supporting means for any desired purpose.

lin operation., the tension means being adjusted to exert the desired pressure between the rolls, power is applied to shaft 13 from any desired source which causes rotation of the driving gear. 13 which through the pinion 19 rotates roll 6 and its attached pinion 10, which, in turn rotates pinion 11 and the lower roll 7, extension 9 of the .lower roll turning freely in its bushing 14:.

Should an abnormal quantity of clothes be fed between the rolls or should a bunching of the same occur, or should the operator be cau ht between the rolls, so as to force the ro away from each other a distance equal to or greaterv than the length of the teeth on the driving gear, as indicated by the dotted lines in Fig. 1, power will no longer be communicated to the roll 6 which will remain idle, and since roll.7 depends upon its connection with roll 6 for its movem5 ment, y,it too will remain idle until the articles separating the rolls are removed, at

which time the spring 21 together with the weight of the parts will again engage pinion 1 9 and gear 13 for normal operation. This u@ rou i disengagement takes place automatically Without any care on the part of the operator, and during the disengagement there isr no tendency whatever for the rolls to turn thus drawing the articles further between them, which acilitates removal or" the same. lt also prevents choking of the rolls `trom throwing an abnormal load upon-the motor driving the Wringer thus preventing the burning out of the electric motor which is the type usually employed.

lit is to be noted that although the mechanism described is preferably used with some type ot tensioning means 'for the rolls in' Which a substantially uniform pressure is maintained throughout the extent of the rolls, for instance as illustrated in the draw-1 ings, yet the same is equally adapted for use in connection with many of the well lrnovvn types of tensioning devices and in no Way interferes With the adjusting mechanism and release devices commonly employed. lt is also noted that adjustment for varying the point at which this disengagement will take place is made by simply increasing or decreasing the tension of the particular tensioning means employed.

llt is thus seen that l have provided a device simple in construction, easily adjusted te varying conditions of operation, automatic in action and one which Will prevent damage to the operator, to the driving motor, and to the articles being Wrung.
