r 7 Claims.

The object of my invention is to provide a wringer for washing machines of very simple, durable and inexpensive construction.

More particularly, it is my object to provide it a wringer structure having certain of the features of the Perkins patent, No. 1,902,580, which has certain advantages thereover, particularly in the provision of a replaceable bearing for the lower wringer shaft and the particular means for preventing the clutching of the wringer mechanism with a driving shaft during the swinging of the wringer from one position to another and the provision of a protector for the upper wringer roll, and in the provision of anti-friction devices adapted to engage with a minimum of wear when the upper wringer roll is swung to clutching position.

Another object is to provide novel means for moving the upper wringer roll from one position to another.

With these and other objects in view, my in-= vention consists in the construction, arrange ment and combination of the various parts of my wringer for washing machines, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure l isa frontelevation of a wringer structure embodying my invention.

Figure l-A is an elevation of the cam block, which cooperates with the upper wringer roll.

Figure 2 is a vertical, detailed, sectional vie taken on the line 2-2' of Figure l.

Figure 3 is a perspective view or the slotted cap used on the wringerhead.

Figure 4 is a detailed, sectional view taken on the line 3-fil of Figure l; and

Figure 5 is a similar view taken on the line 5-5 of Figure 1.

s In the accompanying drawings, i have used the reference numeral Ill to indicate generally a tub. At the side of the tub is anupright tube or sleeve 8 through which extends a shaft l2 operated from any suitable source of power-,and which forms the driving shaft for the wringer mechanism.

Supported on the sleeve ,ll is a sleeve 83 fastened to the tub ill by meansof a bracket i l. The lower part of thesleeve i3 fits snugly on the sleeve 11 i and the upper part at 83a is diametrically spaced therefrom. 7,

, Supported on the sleeve I l is what I will call the wringer head A, which in turn supports the wringer irame B. The wringer head A, comprises a horizontal tubular member 15 closed at one end, as at I6, and having atubular downward extension l'l' telescopically receiving the sleeve ll and partially telescopically received in the upper end of the sleeve I3.

I preferably interpose between the tubular sleeve 11 and the sleeve II, the bronze bushings l8 and it.

The wringer head and wringer are mounted to swing around the tube I; which might be called a post, so that the wringer may be positioned over the tub Ill or over other tubs or the like, de-

pending upon its 'position with relation to the tube or sleeve H. I

The upper end of the shaft I2 is squared as at and has non-rotatably mounted on it a beveled gear 2!. A suitable bushing 22 is interposed between the hub of the gear 2i and thewall of the sleeve ill. a 7

Received within the sleeve portion [5 of the wringer headA spacedfrom the closed end Hi thereof. is an annular ring or the like 23, which is arranged for limited movement longitudinally of the sleeve I5 and for limited rotary movement. A screw 24 extends upwardly from the ring 23 through aslot 25 in the sleeve l5, and travels in the's-shaped slot 26 (Figures 1 and 3) in the cam plate 21 detachably mounted by means of screws or the like on the sleeve l5 by means of screws 28 extended through the holes 2a in the cam plate and into suitable threaded openings in the sleeve 65.

The cam plate 2? is of such material and so arranged that it may be curved end to end to fit in position and may be bent in either direction, n

so that if desired, it may be 'turned end for end and turned over so as to thus reverse its opera= tion for adapting it for any difierence in direction of the rotation of the driving shaft. There may be provided a cover plate 36 for the cam r plate.

The ring 23 may be rotated and slid longitu dinally to the extent permitted by the movement of the head of the screw 25 in the slot 26 by means hereinafter referred to.

It will be seen that the slot 26 is so constructed thatwhen the ring 23 is moved lengthwise of the sleeve iii, the travel of the screw 25 in the slot '28 will cause the ring 23 to be so moved lengthwise of the sleeve it. A

The purpose of this movement of the ring 23 lengthwise in the sleeve I5 is to effect clutching action as hereinafter mentioned.

When the screw head is in the central part of the slot 2! the clutch members are in neutral position.

The ring 23 has in its lower part a recess 3|, which when the parts are in neutral position just 5 mentioned registers with the detent rod]! (Figure 1) slidably mounted in the apron 33 formed on the sleeve II.

In thelower end of the detent rod is a head as. f

A spring II normally tends to keep the detent -i0 rod in its lower position. The'upper part of the permit the upper end of the rod to travel in the recess 3|.

After the wringer is swung around, the head 34 slides on the upper edge of the sleeve por- 26 tion Ila and the wringer. can not be thrown into gear until the head reaches another notch 36 when the spring 35 will force it downwardly and withdraw the rod u-from the recess 8i.

A tubular shaft 38 is iournaled in a bearing 39.

in the closed end of the wringer head- A and in the ring 23. flxed on it the beveled gears ll andll and their connecting sleeve 42. The shaft 38 must'slide with the ring 23 because the beveled gear 4! abuts against the sleeve 26 on one side thereof,

and the shaft ll has an annular flange 43 engaging the opposite side of the ring 23. s

The lower wringer roll 44 has a shaft 45. We'

show the bearing at one end only oflthe shaft ll, but itwill be understood that thebeafing at the other end is the same. I

The shaft end has an ordinary bushing or the like ll, which is received in a removable bear- 1 ing 41, which has a cylindrical bore andis 45% squaredin its external sectional outline as illustratedinl'lgurelandisseatedinanangular bearing socket 48 formed in the wringer frame.

The main pressure on the lower wringer roll...

is downward and .it would be observed bearings 50 that the bearing 41, if it should become worn,

may" be given a quarter turn, for thus increasing e. The left-hand end of' the shaft ll as shown in I'lgure'l is received'incne endof a sleeve ll -andisflxedthere'to,

Mounted on the shaft 88 is a cross pin II, best shown in Figure 5, on which are anti-friction rollers ".1. The pin II and rollers II are slidably received in an elongated slot I2 in the end of the 9 sleeve opposite the shaft I. Thus the shaft cam block" has an inwardlyprciecting flange II. From one side only of the cam block II. there extends downwardly a flange". sing it extends from each flange Il inwardly lengthwise of the'wringer frame. The cam block- I! above the lo'wor end of the flange U is substan- The shaft 38 is slidable and has aoiaaai tially narrower than the casing frame B from front to rear and narrower than the cap 59 as shown in Figure 6. Below the flange 51-, the cam block 55 is wider and extends laterally to the side walls of the casing B.

Below the flange 51 at each side edge of the cam block 56 is a flange extending close to the wall of the casing B lengthwise of the wringer frame. 7

At the lower end of each flange 60 is a laterally l0 projecting internally-apertured and threaded lug ti, The upper ends of the tension bolts 82 are threaded into the lugs and project downwardly through the shoulders 54. (Figure 4). The

lugs 6i preferably rest on washers I. Onthe II lower ends of the tension bolts 82 are the nuts 6 On each bolt 62 is a coil spring 68 between the nuts 84 and the shoulder 54; Thus the cam block 55 is held down under spring tension, but may be moved upwardly slightly against the tension of the springs 85.

Formed on the cam blocks below the lower end of the flange 5'! and connected with the flanges 60 arelugs 86 which project later'ally toward each other as shown in Figure 4 and the under inner 25 edges of which are inclined at 61 for functioning as hereinafter described. v r

Mounted on the cam blocks 5! above the inner ends of the respective lugs I are laterally spaced T'anti-friction rollers 8.. 30 It may be mentioned at this point thatthe caps 59 are, connected to the cam blocks 55 by means of angle brackets 89 (Figure 4). Onearm of each angle bracket 88 is fastened by a 1 screw or the nine- 10 to the lug 5s and has in its 35 other angle a vertically elongated slot H, which receives a pin 12 extending inwardly from the wall of the cap I9.

The parts'are arranged in such manner that the cap may be lifted slightly, thus raising the 40 pin I2 in the slot Ii, whereupon the cap may be tilted over for allowing access to the parts below it and for permitting removal of the parts.

The upper wringer roll 13 has a shaft 14, which projects from the ends of the roll proper, and has on it the bushings 16. Each end of the shaft I4 and each bushing II is journaled in a hearing 16 formed on a casting II.

l ormed on the casting "above the bearing 10 is a bearing n in which is journaled the shaft 0 1!. On the shaft I! is a roller lQ'on substantially the same vertical plane as the rollers 08.

The parts arefso arranged that by swinging the upper wringer roll 18 bodily laterally the clutch mechanism can be operated. 7 When the upperwringer roll is immediately above the lower wringer roll. the parts are in For affording the operative relation between the upper wringer roll and .the clutch mechanism, I provide at the left end only of the wringer structure shown in Figure 1, the yoke 04 reeeiv-. lag between itsarms the bearing ll. 4 At its lower part, the yoke r4 is curved toward the wringer head and is connected with an annular ring I journaledlin a suitable opening I. in the wringer frame 8. (Bee Figures 1, 4 and 5.) I Projecting toward the wringer head from the ring' as are a pair of pins 01. whichslide m" UOI ILAIILLO; I'LUIU suitable holes 88 in the ring 28 (see Figures 1 and 5).

In the edge of the ring 85 are three notches 88 arranged to coact with a spring-pressed detent ball 88. The ball 98 and the spring 8|, which tends to press it toward the ring 85, are received in a hole 92 in the end wall of the wringer frame B, in line with the opening 88 in which the ring 85 rotates. The notches 88 are so located as to permit the detent ball to tend to hold the parts in place when the upper wringer roll is swung to neutral position or to position for placing either of the gears 484| in mesh with the gear 2|.

A drain board 93 has at its ends up-turned flanges 84 journaled on the ends of screw pins 95, projected through the end walls of the easing of the wringer frame B.

The left-hand screw pin 85 also holds the spring 9| in place.

At the left-hand end of the drain board 83, it has an arm 96 extending upwardly, bifurcated at its upper end, to receive the pin 81 projecting from the ring 85. This is for the purpose of furnishing means for tilting the drain board 93 according to the position of the upper wringer roll.

For furnishing additional protection, I have extended between the upper parts of the cast ings 11 between the caps 83 a. rod 88 on which is loosely supported a roll protecting cap 88 (see Figures 1 and 2).

. Operation It will have been observed that the wringer head A is rotatably supported on the upstanding sleeve so as to permit the head and the wringer proper supported thereby to swing on a vertical axis at the center of the sleeve I.

The head A is bolted or screwed to the wringer frame B in any suitable manner. The proper wringer frame end has the hole 88 in which the ring 85 rotates and which affords means for the insertion of the mechanism connecting the wringer proper with the mechanism in the head.

It will, of course, be understood that the sleeve 49 hereinbefore referred to projects through the hole in the center of the ring 85.

The parts are so constructed and arranged that the upper wringer roll 13 may be swung from position immediately above the wringer roll 44 laterally in either direction for operating the clutch and thus causing the wringer rolls to be operated in one direction or to be operated in the reverse direction. For example, if the operator grasps the handle 82 of the clutch control and release bar 8| and swings it from its neutral position shown in Figures 1 and 4 toward the left as shown in Figure 4, the clutch members will be connected. This would mean that the operator standing facing the wringer shown in Figure 1 would pull the handle toward him. The caps 83 engaging the upper ends of the castings 11 would tend to pull the rollers 88 from position shown in full lines in Figure 4 toward the dotted line position shown in that figure, and the wringer roll 13 would be swung from its full line position shown in Figure 4 toward its dotted line position showr. therein.

The bearings 16 (Figure 1) will engage the inclined faces 6'! of the lugs 66 (Figure 4) and the rollers 88 would engage the left-hand rollers 68 (Figure 4) so that if the upper wringer roll is forced to clutching position, the rollers 88 and 88 afiord anti-friction means which greatly reduces the wear, which I have found to otherwise occur where two cam surfaces are slid together or where a roller is caused to travel over one fixed surface. The adjustable set screws I88 in the lugs 66 engage the rollers 88 and thus limit 5 the swinging movement of the upper wringer roll.

I might mention at this time that when the roller is swung to its position shown by dotted lines in Figure 4, the clothes are fed in from the left and the pressure of the wringing operation is such that the upper wringer roll will retain its then assumed position during the wringing operation. When the upper roll is thus swung laterally, the

yoke 84 is also swung for rotating the ring 85. 15

The pins 81 projecting from the ring 85 into the a ring 23 serve to thus rotate the ring 23 for 9. limited distance. causing the head of the screw 24 to travel in the slot 26 and to move the ring 23 and the shaft 38 lengthwise for throwing the 20 clutch into gear. Whether the gear 48 or the gear 4| is the one thrown into connection with the gear 2| depends upon whether the roll 13 is moved laterally one way or laterally the other way.

The detent ball 98 helps to hold the parts in 1 position when they have been moved for connecting the clutch members and when they are in control.

If it is desired to swing the wringer from one position around the sleeve I to another position, it will be observed that normally when the wringer is in wringing position, the head 34 on the detent rod 32 will project into one of the recesses 38, so that the wringer can not be swung around the sleeve When it is desired to swing the wringer, the clutch structure must be moved to neutral position, so that the handle 31 may be grasped for raising the detent rod 32 for bringing its upper 40 end into the recess 3|. The handle must be held until the swinging movement of the wringer has started. Then the head 34 will slide on the upper edge of the member |3a until the next recess 36 is reached. Thereupon the spring 35 45 will force the head 34 into such next recess 36.

Then the wringer can be thrown from control for operating the clutch to rotate the wringer rolls in either direction desired.

If it is desired to swing the wringer further, the 50 handle 31 must again be operated to raise the detent rod 32.

At the present time, I consider the most impsrtant feature of my invention to be the provision of the anti-friction means which reduces the wear on the cam plate to a minimum. This I have found to be of almost vital importance in. a wringer of this type. The upper wringer shaft can roll on the cam faces with which it coacts' and the use of the rollers 88 and 68 reduces the wear on the cam plate to a minimum.

It will. of course, be obvious fro-m the foregoing description that when the wr'n'rer is .in operative position and the clutch members are engaged, if any trouble occurs the operator by a simple push on the bar 8| will move the parts -to where the clutch is in neutral and theoperation of the wringer will be stopped.

The bar 8| with its cap members 83 at the end affords a means for operating the casing or bear- 70 ing bracket 11 and also functions as a quick clutch release and also serves as a means for holding the rod 88 in place.

It will be observed that structure has been provided which is convenient for the removal of the upper wringer roll. The clutch and release bar 8| may be removed by simply lifting it upwardly. Then by tilting the caps 56 on their piv ot pins 12, the upper wringer roll can be lifted, and by swinging the roller 80 laterally until it clears the flange 56 (see Figures 1 and 4), the upper wringer roll can be lifted bodily out of the frame.

It will also be observed that it is an easy matter to remove the lower wringer roll from the frame.

All of this, of course, makes for convenience in assembling and installing the parts.

It is my purpose to cover by my claims any modifications of structure, which may be included within their scope and within the scope of my invention.
