CLOTHES WRINGER.

Application filed December 10, 19.25.` Serial No. 74,498.

My present invention relates to clothesv wringers, and has for its object to improve the same in the several particulars hereinafter noted.

To the above end, the invention consists of the .novel devices and combinations of devices hereinafter described and defined in the claims.

Fig. 8 is a view partly in plan and partly in horizontal longitudinal section, taken on the line 8-8 of Fig. 6; and

Fig. 9 is a view in transverse vertical section showing a modification of the rolls.

Referring first to the invention as shown in Figs. 1 to 5, inclusive, the numerals 10 and 11 indicate, respectively, co-operating upper and lower wringing rolls, the former ;of which is pneumatic and the latter of which is solid and may be made from a rubber composition or any other suitable material. The lower roll 11 is secured to the intermediate port-ion of a shaft 12 journaled in anti-friction bearings 13 mounted in the end members 14 and 15 of a tilting frame, and which end members are rigidly connected by shouldered nut-equipped crosstierods 16 that are circumferentially spaced in respect to the pneumatic roll and located above the same.

Formed with .the frame end member 14 is a heavy sleeve-like trunnion 17. This trunnion 17 and the outer end of the shaft y' 12 are turnably mounted in open seats 18 and 19, respectively,'in the upturned ends of a wringer support 20. The upper face of the wringer support 20 in vertical transverse section is reversely beveled from the center thereof to afford drain surfaces 21.

The pneumatic roll 10 is held for wringing engagement with the roll 11 by an abutment 22 in the form of, a cage in which the opposite side of the pneumatic roll 10 from the roll 11 lies. This abutment 22 comprises a plurality, as shown six, circumferentially spaced tubular shafts 23 through each of which axially extends a xed `solid shaft 24 having reduced ends that are mounted in seats in the frame end members 14 and 15. Mounted on the fixed shafts 24 at the ends of the tubular shafts 23 are end hubs 25. Long anti-friction roller bearings 26 are interposed between the shafts 23 and 24 of each pair and held against endwise movement by the end hubs fast with the tubular shafts 23 for common rotation therewith. The abutment 22 extends over substantially 180 of the entire circumference of the pneumatic roll 10 and throughout the entire length thereof and securely holds said pneumatic roll 10 in its propery wringing relation to the rollf 11 and at the same time permits said pneumatic roll 10 to fioat in respect to the roll 11.

The abutment 22 also performs another important function in that its tubular shafts 23 are positively driven from the shaft 12 and afford a peripheral friction drive for the pneumatic roll 10. To drive the tubular shafts 23 there are applied to their inner hubs 25, spur pinions 27 that mesh with 'an idle intermediate spur gear 28 liournaled on the frame end member 14, and which idle gear meshes with a spur gear 29 keyed to the shaft 12.

The wringer frame is free -to be tilted about the axis of the shaft 12 from one side to the other of a vertical plane, and this tilting movement is limited by stop surfaces 30 on the upturned ends of the wringer support 20, and which stop surfaces are engaged by the frame end members 14 and 15.

-A carrier 31 in the form of a fiat yoke-like bar` the bodv of which extends horizontally and longitudinally over the wringing frame, is provided with a push bar, as wil'l presently appear. The inner arm of the carrier 31 has a bore through which the trunnion 17 extends and is held against axial movement on said trunnion between the frame end member 14 and the adjacent upturned end of the wringer support 20, and the other arm of said carrier has a bore through which the respective end portion of the shaft 12 extends. Obviously, the carrier 31 is supported on the trunnion 17 and shaft 12 for swinging movement circumferentially of the wringer support and this swinging movement is limited by pairs of horizontally spaced pins 31 on the frame end members 14 and 15 arranged to engage the arms of the carrier 31 and move said carrier with the wringer frame during its tilting movement from one side of a'vertical plane to another. The outer arm of the carrier 31 has an inturned end 32 which extends under a short hub 33 on the respective upturned end of the wringer support 2O and through which the shaft 12 extends and holds said shaft in the open seat 19.

Formed with the frame end members 14 and 15 are upper and lower inwardly projecting guard flanges 34 and 3,5, the former of which are concentric with the pneumatic roll 10 and extend outward of the abutment 22, and the latter of which are concentric with the roll 11. A segmental housing plate 36 has its end portions telescoped under the guard flanges 34 and covers the roll 10, crosstie rod 16 and abutment 22. Between the opposing faces of the rolls 10 and 11 the guard flanges 34 and 35 on each frame end member 14 and 15 are connected by a guard member 37 which is channel-shaped in cross section and affords a water drain 33.

A partition comprising a pair of laterally spaced plates 39 with a piece of felt 40 inter- 'posed therebetween is placed in the inner guard flanges 34 and 35 between the ends of the rolls 10 and 11 and the pinions 27 and gears 2S and 29 to house said pinions and gears. Preferably, the housing formed by the frame end member 14, its guard flanges 34-35 and 37 and partition 39 will contain a non-drip oil in which the pinions 27 and gears-,28 and 29 run.

Underlying the roll 11 is a drain board 41 having at its transverse center trunnions 42 journaled in the upturned ends of the wringer support 20, and which trunnions are so arranged that the drain board 41may be tilted to rest on either one of the drain surfaces 21. This drain board 41, as shown, is formed from sheet metal and has at its longitudinal edges upwardly and inwardly cfurved stripper blades 43, either one of which may be positioned to closely engage the periphery of the roll 11 by tilting the drain board 41, to prevent handkerchiefs or other articles from winding on said roll.

The stop surfaces 30 are arranged to posi tion the wringer frame with the axes of the lll board 41 and properly position the same durl ing the tilting action of the wringer frame.

Formed in each stripper blade 43 is a plurality of drain holes 45. A pin 46 is in serted through the inner upturned end of the wringer support 20 above the trunnion 17 and holds said trunnion in the open seat 18. Obviously, the pin 46 and the lug 32 hold the wringer frame interlocked with the wringer support 20 against movement from the open seats 18 and 19.

rlhe pneumatic roll 10 is in the form of a tube formed from spirally Wound fabric, cord, or other suitable material having preferably a rubber facing, and with its ends turned inwardly and backwardly. The ends of the pneumatic roll 10 are closed by metal heads, each of which comprises a pair of nested dish-like plates 47 adjustably connected by a nut-equipped draw bolt 48, and between which plates the respective end portion of said roll is clamped. r1 he inner bolt 48 is extended outward of the respective end of the pneumatic roll 10 to afford a stop for engagement with the partition 39 to prevent endwise drifting movement of the roll 10 toward said partition. A stop 49 in the form of a cup is secured to the outer head 47 by its nut-equipped bolt 48 and arranged to engage the frame end member 15 to prevent endwise drifting movement of the pneumatic roll 10 toward the same. The outer bolt 48 has an axial bore 50 which opens into the pneumatic roll 10 and has mounted therein a check valve, not shown, and through which bore the pneumatic roll 10 may be inflated from an air hose, not shown, inserted through an aperture 51 in the frame end member 15, and applied to the outer end of said bolt. A dust cap 52 is applied to the outer bolt 48.

The wringer support 20 is bolted to a housing 53 on the upper end of a tubular standard 54 turnably mounted on a washing machine, or other support not shown, and supports the wringer for horizontal swinging movement. A latch, not shown, will be provided for #securing the standard 54 from turning to hold the wringer set in different predetermined positions. The inner end of the shaft 12 extends into the housing 53 through the trunnion 17 and a bossed opening in said housing, and has keyed thereto a bevel gear 55. A vertical shaft 56, driven by an electric motor or otherwise, extends upward through the standard 54 into the houslng 53 and has mounted thereon a pair of bevel pinions 57 connected for common movement by .a long sleeve 58 through which the shaft 56 extends, and which sleeve and pinions are keyed at 59 to the shaft 56 for common rotation therewith but with freedom for.

axial sliding movement thereon. The p1nions 57 are located, the one above and the other below the gear 55, and when in an intermediate or neutral position, both thereof are out of mesh with said gear, as shown in Fig. 2. By raising the sleeve 58 the lower pinion 57 is moved into mesh with the bevel gear to drive the rolls 10 and 11 in one mounted on the shaft 56 for compound axial sliding and turning movements.

On the back of the shipper member 60 is` a cam stud 61 which works in a cam channel- 62 on the housing 53. Formed with the upper end of the shipper member 60 is a sleeve 63 into which the upper end of the shaft 56 extends, and which sleeveextends through a bosscd opening in the top of the housing 53. Secured to the upper end of the sleeve 63 1s a crcsshead 64 having a segmental socketlike channel 65 which extends transversely of the shaft 56 and on opposite sides thereof.

The ends of the channel 65 are closed by pins 66 secured to the crosshead 64. For oscillating the shipper member 60 to move its cam stud 61 in the channel 62, I provide a push bar 67 on one end of which is a ball 68 mounted in the channel 65 for sliding movement, and at the other end of said push bar is a hand piece 69. The push bar 67 is mounted on the horizontal or intermediate portion of the carrier 31 and is held for straight line endwise movement by a pair of lcoplike keepers 70 and 71, the former of which is secured to said push bar and slidably mounted on the carrier 31, and the latter of which is secured to said carrier andV the push bar 67 is slidably mounted therein.

When the wringer frame is in one of its extreme tilted positions and held by the respective stop surfaces 30 the carrier 31 is held positioned by the uppermost pair of sto ins 31 on the wrineer frame and sup- P P s for the opera-torl to draw the push bar 67 away from the crosshead 64 to swing said crosshead about the axis of the` shaft 56 which oscillates the shipper member 60 and causes its cam stud 61 to move in the cam. channel 62 and impart an axial movement to the pinions 57 and cause the proper one to mesh with the gear 55. To stop the rotation of the rolls 10 and 11, it is only necessary to push the push bar 67 endwise toward the crosshead 64 to oscillate the shipper member 60 and move the pinions 57 into neutral position or in case of an emergency a continued movement of said push bar in the same direction will reverse the direction of rotation of said rolls. To wring clothes from the other side of the rolls 10 and 11 the wringer frame is tilted to the opposite side of a vertical plane until stopped by the respective stop surfaces 30, and during this tilting of said frame the lowermost pair of pins 31 will be brought into engagement with the carrier 31 to move the same with the wringer frame and position the push bar 67 at the other end of the crosshead 64.

To again drive the rolls 10 and 11, the push bar 67 is pulled away from the crosshead 64, and to stop or reverse said rolls the push bar 67 is moved toward the crosshead 64. From the above description it is evident that the push bar 67 is always moyed in the same direction, to wit: away from the cro-sshead 64 to start the rolls 10 and 11, and toward said crosshead to stop or reverse the Same no matter from which side of the wringer clothes are being Wrung.

As the pneumatic roll 10 is without a shaft or trunnions it is free to float inrespect to the roll 11 and its axis does not have any definite relation to the axis of the roll 11. By thus mounting the pneumatic roll 10 for a floating movement in respect to the roll 11 it is free for contraction or'expansion the entire distance between the roll 11 and abut? axis of a co-operating roll.

Obviously, the floating pneumatic roll 10 produces just as eh'icient wringing action on thin or on heavy materials or on articles that have a varying thickness longitudinally of the rolls. In case a person gets his fingers or hands between the rolls 10 and 11 the pneumatic roll 10, due to its elasticity and floating action, will not produce a crushing or pinching action.

By tiltably mounting the wringer frame and supporting the samewith the axes of the rolls 10 and 11 in a common plane that is oblique to a vertical plane, the operative sides of the rolls 10 and 11 are always uppermost whether said rolls are driven forward or backward. With the rolls 10 and 11 thus supported it is only necessary to hold an article to be wrung thereby above said rolls and' allow the same to drop thereon to cause the same to be fed between the rolls, thus eliminating all danger of a person having his fingers or hand caught by the rolls trying to start the feeding action, as is often the case when `ordinary wringers are used in which the axes of the rolls are in a vertical plane.

As the ends of the pneumatic roll 10 are loose and flexible they are free to move toward or from each other during the contraction and expansion of the roll l0 during its wringing. The guards 34-35 and 37 cover the relatively stiff end portions of the pneumatic roll 10 so that the actual wringing surface of said roll has the same elasticity throughout its entire length. Any water that is carried over the pneumatic roll l0 during its wringing action will be collected by the housing 36 and be carried back by the drains 38 to the guard Hanges 35 and thence onto the drain board 41 where it escapes through the lowermost drain holes 45 onto the underlying drain surface 2l. As previously stated, the movement of the wringer frame from one tilted position to the other automatically and positively moves the drain board 41 into its proper relation with the drain surfaces 2l.

Referring now to the invention as illustrated in Figs. G, 7 and 8, the numeral 72 indicates a frame in which is journaled cooperating rolls 7 3 and 74 that are identical with the rolls 10 and 1l, respectively. rlihe abutment 75 for the pneumatic roll 7 3 comprises circumferentially spaced shafts 76 journaled in the frame 72 and over which runs an endless belt 77 that affords a peripheral friction drive for said roll 73. To prevent drifting of the belt 77 on the shafts 7 6 the same is provided on its inner face with a plurality of endless ribs 78 that run in axially spaced circumferential grooves 79 in the peripheries of said shafts. The shafts 76 are driven from the shaft 80 of the driven roll 74 by a spur gear S1 keyed to said shaft and meshing with an idle spur gear 82 journaled on the frame 7 2, and which idle gear meshes with spur pinions 83 on the shafts 76. Referring now to the invention as shown in Fig. 9 there are illustrated two co-operating pneumatic rolls 84 and 85 that are identical with the rolls 10 and 73, and the abutment 86 for each roll 84h and 85 is identical with the abutment 22 and aord peripheral frictional drives for both of said rolls.

Referring again to the invention as illustrated in Figs. 1 to 5, inclusive, I provide a loclrv for holding the wringer frame in either one of its tilted positions, and which lock, as shown, is in the form of a springrejected bolt 87 mounted vin the outer end of the wringer support 20 and arranged to be pro-- jected into either one of a pair of circumferentially spaced holes 88 in the frame end member 15.
