PENNSYLVANIA, A CORPORA- warmem Application led February 5, 1921. "Serial No. 442,622.

To all whom t may concern.'

Be it known that I, `EDGAR l). MIsNnn, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful improvements in Wringers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to wringers and refers particularly to the power driven type. One object of the invention is to provide a wringer in which the pressure between the pair of rolls in frictional contact with each other, is predetermined and cannot be readily varied by the operator. object is the provision of equalizing means for facilitating the simultaneous and equal movements of the opposite ends of one of the rolls from the other. Further objects of the invention reside in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth. Y

In the drawings:

Figure 1 is a side elevation partly in section of a wringer embodying vmy invention;

Figure 2 is a top plan view thereof;

Figure 3 is a central transverse cross section therethrough;

Figure 4 is a cross Vsection on the line 4,-4 of Figure'l;

Figure 5 is a side elevation of the top plate;

Figure 6 is a able block.

Figure 7 is a fragmentary sectional view of a balancing means for the resilient upper roll holding member, and

Figure 8 is a sectional view through the top late.

1 1s the frame of the wringer formed of the complementary sections 2 and 3 which are suitably secured to each other as by perspective view of a movf means of the bolts 4. 5 is the power driven roll and 6 the cooperating roll. The shaft 7 of the power driven 'roll is rotatably mounted in suitable bearing blocks 8 at its op site ends and has the gear 9 at one en which is adapted to mesh with the gear 10 upon the shaft 11 of the cooperating roll. 12 are wooden bearing blocks impregnated Another with lubricant and located at the opposite ends of the frame 1, ythese bearing blocks having the bearings 13 for engagement by the shaft 11.

F or moving the `cooperating' roll 6 toward and away from thepower driven roll 5, there is the following construction: 1t is a resilient member extending above the cooperating roll and having its opposite ends engaging between the straps 15 and the bearing blocks 12. 16 is a vertical shaft longitudinally movable in the top plate 17 which is secured centrally to .the top of the frame 1. This shaft is secured at its lower end to the clipy 18 by means of the pin 19 engaging in the annular groove 20 in the shaft and extending transversely through the clip. The lower portion 21 of the clip is U-shaped to embrace the resilient member 14. 22 are coil springs at opposite sides of the clip, connected at their lower ends to the projections '23 upon the clip and at their upper ends to' suitable eye bolts 24 depending from the top plate 17. With this arrangement as thus far described, the

shaft 16 is adapted to tension the resilient member 14: to press the cooperating roll 6 intoA frictional contact with the power driven roll 5 while the coil springs 22 upon release of the shaft are adapted to retract the resilient member 14 to move the cooperating roll away from the power driven roll.

For the purpose of holding thev cooperating roll 6 in frictional contact with the' power driven roll 5, the shaft 16 has the transversely extending pin 25 near its upper end, which pin is ada. ted to pass through either of the pair of iametrically opposlte slots 26 in the top plate and to engage the lower faces of the lugs 27 between the pairs of slots upon slight rotation of the shaft. The lower faces of these lugs are preferably hollowed as at 28 to position t e pin 25 and prevent accidental rotation of the shaft 16 and the consequent disengagement of the pin from the lugs. 29 is a handle above the wrinoer frame 1 and at the upper end of theslliaft 16 by ineens of which the shaft 16 is moved inwardly to tension the resilient member 14 and press the rolls into frictional contact with each other and also by means of which the shaft 'is slightly rotated to either engage the pin with the lower faces of the lugs 27 or disengage the same. In order to permit of easier engagement of the pin with the lower' faces of the lugs,

their sides are under-cut as at 30, so that. after the shaft 16 has been longitudinally moved inward so that the pin 25 can engage the under-cut sides, rotation of the shaft will force the pin to ride over the under-cut sides and downwardly into engagement with the recesses 28 upon the'lower sides of the lugs. With this arrangement it will be seen that the transversely extending pin is a stop for limit-ing the outward movement of the shaft 16 and'maintaining the resilient member 14 under tension to press the rolls 'in frictional contact with each other.A To trip the mechanism and permit the coil springs 22 to operate, the shaft 16 can be slightly rotated by swinging the handle 29 when the pin 25 will register with one pair of the slots 26.

For the purpose of preventing rotation of the handle 29 when moving away from the top plate 17, each of the lugs 31 between the slots 26 has substantially vertical sides which' extend above the lugs 27. This arrangement also facilitates the operator in registering the pin 25 with the slots, since bv moving the handle 29 downwardly until the pin 25 engages the top plate 17 and then rotating the handle, the sides of the lugs 31 will engage the pin at which time the latter is in registration with a pair of slots.

The sides of the complementary sections 2 and 3 of the wringer frame 1 have t-he vertical central bulging portions 32 in each of which there is the vertical groove 33. The clip 18 has the longitudinally extending pro'lections or keys 34 on its opposite 'sides w ich engage in the Lgrooves 33 to guide the clip 1n its up and down move ments.

To facilitate the simultaneous and equal movements of the opposite ends of the cooperating roll 6 away from the power driven roll 5, the lower end of the shaft 16 is receed as at 35 to receive the coil spring 35 When the shaft 16 is in its innermost position to tension the resilient member 14, the latter rests against the lower end `of the shaft;` but when the mechanism is tripped, the spring 35 will clamp the resihent member 14 against the base 36 of the `U-shaped portion 21 of the clip to therebyprevent rocking movement of the resilient member relative to the shaft. This'resilient member .s preferably formed with the lug 37 whichis engageable within the lower convolution of the coil spring 35 to longitudinallylposition the resilient member.

The bearing ocks 12 also preferably have the sides 38 tapering to avoid too great a frctionaliresistance to their movements.

' To limit the upward movement of the. coax operating roll 6 under the action of the coil i ends of the rolls, inwardly away from the ends of the wringer frame, the lower ends` 40 of the flanges 39'extends beneath the ends of the power driven roll and are inclined inwardly.

The straps 15 are secured to the movable bearing blocks to reinforce and prevent splitting of the same as well as to secure the ends of the resilient member 14 thereto. Each bearingblock is formed of wood impregnated with a lubricant and the grain of the l wood extends longitudinally of the block and perpendicular to the axis of the hole or bearing 13 therein. The strap is of inverted U-shape and extends transversely of the grain of the wood, so that its arms 41 embrace the layers of the block. These arms are secured to each other by suitable means such as the rivet 42 .extending through the block; and preferably, the arms are set into the sides of the block.

From the above description, it will be readily seen that I have provided a simp'lc construct-ion of wringer in which a predetermined ressure is applied to force the rolls into rictional contact with each other. This is.y due to the fact thatfthe shaft 16 has a predetermined position relative 'to the power driven roll when the latter 'is in frictional contact with the cooperating roll. To

vary this compression, washers 43 between the top plate 17 and the top of the wringer frame may be added or removed, but this necessitates partial disassembly of the wriuger.
