JOHN S. EASON, OE MINNEAPOLIS, MINNESOTA, A SSIGNOR TO TWIN CITY WRINGEB COMPANY, OF ST. PAUL, MINNESOTA, A CORPORATION OF DELAWARE.

WRINGER.

Application filed May 17, 1921. Serial No. 470,242.

To all whom it may concern:

lie it known that 1, JOHN S. EAsoN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Wringers; and I do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable Others skilled in the art to which it appertains to make and use the same.

My invention relates to wringers for scribed and defined in theclaims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views:

Referring to the drawings:

Fig. 1 is an elevation of the improved wringer, with some parts broken away and sectioned;

Fig. 2 is a view principally in transverse vertical section taken on the line 22 of Fig. 1;

Fig. 3 is a view principally in end elevation with some parts sectioned on the line 33 of Fig. 1;

Fig. 4 is a fragmentary view partly in plan and partly in horizontal section taken on the line 44: of Fig. 1; and

Fig. 5 is a perspective view of one of the removable bearing plates.

The frame 6 of the improved wringer is cast as an entirety and is of substantially rectangular formation with a correspondingly formed opening in which the contacting surfaces of co-operating upper and lower rolls 7 and 8 are exposed and, to which rolls, clothes may be fed through said opening from either side of the frame. The top member and side members of the frame 6 are made hollow to aiford ahousing in which all of the parts of the wringer are mounted, with the exception of the rolls 7 and 8.

Laterally spaced guide columns 9, between which the ends of the rolls 7 and 8 project, are afforded by the sides of the end members of the frame 6. The lower member of the frame .6 affords twolaterally spaced tie-bars which connect the guide columns 9 at their lower ends and between which, the. lower roll 8 works. The inner longitudinal edges of the tie-bars 10 and the inner edges of the guide columns 9 are turned inward to afford flanges 11 and 12, respectively, the former of which flanges are above the horizontal center of the lower roll 8 and terminate close to the periphery thereof and assist in directing clothes to the rolls 7 and 8, and the latter of which flanges terminate close to both rolls 7 and 8 and overlap the ends thereof to prevent clothes from getting beyond said ends.

Trunnions 13, for the upper roll 7, are journaled in movable bearings 14: and trunni-ons 15, for the lower roll 8, are journaled in stationary bearings 16. These bearings 14: and 16 are preferably made from hard wood and are bored to afford seats for the respective trunnions 13 and 15. The stationary bearings 16 are removably seated on hearing plates 17 having on their upper faces, pairs of supporting ears 18, which extend outward of the sides of said plates and slidably rest on internal flanges 19 on the lower ends of the guide columns 9. These supporting ears 18 also hold the stationary bearings 16 in position. The sliding movement of the bearing plates 17 on the flanges 19, under the stationary bearing 16, is limited by the engagement of the ears 18 with stops 20 on the transverse portions of the frame 6.

Laterally spaced pairs of lugs 21, on the opposing ends of the bearing plates 17 are provided with segmental slots or channels 22 from which is supported a drain board 28, of novel construction. This drain board 23 is formed from a single sheet of metal having rolled longitudinal edges 24 and upturned ends 25 with segmental upper edges, which have correspondingly formed outstanding flanges 26 slidably mounted in the channel 22 and support the drain board 23 from the bearing plates 17 with freedom for adjustment so as to drain water, wrung from clothes passing between the rolls 7 and 8, on either side of the frame 6. On the bottoms of the bearing plates 17 are transverse lugs 27, by which said bearing plates m be slid on the flanges 19' to and from positions under the stationary bearings 16 and carry the channel-equipped lugs 21 into and out of interlocking engagement with the segmental flanges 26.

Interposed between the bearings 14 and 16 are coiled springs 28 mounted in recessed seats 29 bored in the opposing faces of said bearings and under strain to lift the movable-bearings 14 and separate the rolls 7 and 8. These seats 29 not only hold the springs 28 in positionbut permit said springs/co be of suflicient length to lift the move le roll 7 the desireddistance above the roll 8. On top of the movable bearings 14 are combined wearing plates and guides 30,

- the latter of which copper-ate with the guide columns 9 to guide-the movable bearings 14.

The lower, roll 8 is driven from a motor or otherwise by two-speed mechanism, one

dicated as an entirety by the numeral 31 with the exception of a clutch 32 yieldingly held set by a coiled spring 33 and separably connecting the driving mechanism to the respective trunnion 15 of the lower roll 8. This driving, mechanism 31 and clutch 32 are mounted in a housing 34 bolted to the frame 61 i To release the clutch 32*and stop the driving power to the lower roll 8, there is provided a clutch-releasing, lever- 35 intermedi' ately fulcrumed in bearings 36 on the frame 6 and having a forked lower end connected to a shipper" collar 37 on said clutch. The upper end of the clutch-releasinglever 35 is provided with a cam surface 38 arrangedtobe engaged by a cam surface 39 on the -end:

of the adj acent trunnion 13 of the upper roll 7, when said upper roll has been separated from the lower roll 8 a predetermined distance, to release said clutch against the tension of its spring 33. The upper roll 7 is driven at both ends from the roll 8 by intermeshing' gears 7 and 8 on the respective trunnions 13 and 15.

For holding the upper roll 7 in contact with the lower roll 8 under a variable pressure and for releasing the pressure thereon to permit the rolls to separate under the action of the springs 28, the following mechanisln is provided, to wit; a pair of oppositely extended horizontally disposed pressure levers 40 are intermediately fulcrumed on a pin 41 mounted in the walls of the top member of the frame 6. The outer ends of the levers 40 are forked, and fulcrumed to the prongs thereof, are pressure devices in the form of bell-cranks 42, the horizontal outturned arms of which are provided ou and are provided with cam surfaces 44, which'rest on a twopart head 45. The members of the cam head 45 are laterally spaced and integrally formed with the outer faces of the prongs of a bifurcated lever 46, which works through a slot 47 in the top memlxsr of the frame 6 and projects thereabove where the same may be easily operated. This lever 46 and cam head 45 are fulcrumed on a pin 48 mounted in seats on the side walls of the top member of the frame 6. i i

A' two-part combined pressure and equalizer coiled spring 49 is provided for holding the bell-cranks 42 on the: movable bearings 14 and the sections thereof are mounted between the vertical arms of said bell-cranks" and a floating .abutmentfil). This floating abutment 50 works between the prongs of the lever 46 and'is provided with a longitudinal slot 51,- through which the pin 48 projects and supports the abutment. By reference to Fig. 4, it will be noted that the ends or heads of the abutment 50 are extended for engagement with the sides of the 99 frame 6 to laterally guide said abutment. Pilots 52, on the bell-cranks 42 and floating abutment 50, hold the sections of the spring 49 positioned.

When the lever 46 is in its extreme rightv hand position, the cam surfaces 44, on theinner ends of the levers 4.0, are at the highest points. on the cam head 45 and, hence, exert-their greatest pressure on the upper roll 7 through the bell-cranks 42and movable'bearings14. In this position of the lever 46, the spring49 is under its greatest tension for the reason that the pressure appliedto the bell-cranks 42 causesthe same to move on their pivots in a direction to shorten thedistance between their vertical arms and thereby compressing saidsprings. By adjusting the lever 46to the left, the pressure a on the upper roll 7 and the tension on the spring 49 are progressively hen the lever 46 is moved to its extreme left-hand position, as indicated by broken lines in Fig. 1, the cam head 45 is in a posi tion to entirely release the levers 40, which, i in turn, release the pressure on the upper 115 roll 7 and the tension on the combined-pressure and equalizing spring 49.

From the above description, it is evident that when wringing silk or other thin goods, the lever 46 may be adjusted to its extreme 120 right-hand position, so that the greatest pressure will be applied to the rolls 7 and 8. In wringing coarser or thicker goods, the lever 46 may be adjusted to the left so that thle1 desired pressure may be applied to the 125 re s.

In case the operators hand is caught between the rollsor in the clothes and is being drawn to the rolls, the operator, by moving the lever 46 to its extreme left-hand posidecreased.

tion, may instantly release the pressure on the rolls and allow the same to separate, and the releasing action of the rolls will automatically release the clutch 32 andstop the driving action to the rolls.

Should the clothes, in passing between the rolls, be of uneven thickness and thereby lift one end of the roll 7 higher than the other end, the resulting unequal pressure on the two ends of the upper roll 7 will be automatically equalized by the spring 49. This equalization of the pressure on both ends of the upper roll 7 is highly important as it causes the clothes, passing between the rolls, to be wrung with equal pressure throughout the full lengths of the rolls.

In assembling the improved wringer, all of the parts above the rolls are first put in position. The upper roll, with its bear-V ing 14:, is then inserted in position through the open bottom of the frame 6, and, thereafter, the springs 28, together with the lower roll 8 and its bearings 16, are placed in position, in the same manner. Next, the movable bearing plates 17 are inserted under the fixed bearings 16 by sliding the same on the flanges 19, and, at the same time, with their outer ends lifted so as to pass above the stops 20. During the positioning of the sliding bearing plates 17, the lever 46 must be in its extreme left-hand position, as indicated by broken lines in Fig. 1, so that there will be no pressureon the upper bearings 14 or tension on the spring 49. The drain board 23 is then held so that its flanges 26 will enter the channels 22 in the sliding bearing plates 17 and said bearing plates move, by means of their lugs 27 to which may be applied a screw driver or other tool, toward each other-so as to slide off the stops 20 and onto the flanges 19.

Obviously, the drain board 23 and stops 20 hold the movable bearing plates 17 in position.
