CLOTHES WRINGER.

Application filed March 24, 1920. Serial No. 868,253.

To all whom it may concern:

Be it known that JOHN N. DERSCHUG, of Syracuse, in the county of Onondaga, in the State of New York, has invented new and useful Improvements in Clothes Wringers,'of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in clothes wringers in which the wringer rolls are mounted in a metallic frame for relative radial as well as rotary movement, and are yieldingly held in their pressing positions by a leaf spring, which: is adjustable at will to vary the degree of pressure, in combination with a water board which is slidable transversely of and below the rollers, and tiltable in reverse directions to (guide the clothes as they are fed between an by the wringer rolls in reverse directions.

The main object is to increase the general working efliciency, strength and durability of machines of this character, and, at the same time, to reduce the cost of manufac ture. i

Another object is to provide efiicient and easily accessible means, operable at will, for instantly releasing the tension of the spring after it has been adjusted to produce any desired pressure of the rolls upon the work.

Other objects and uses relating to specific parts of the wringer will be brought out in. the following descriptions:

In the drawings:

Figures 1 and -2- are, respectively, a top plan and front elevation of the wringer embodying the various features of my in vention, a portion of the water board being broken away in Figure 1.

Figure 3 is a longitudinal vertical sectional view taken on line 33, Figure l.

Figure 4-- is a transverse vertical sec tional view on reduced scale taken on line 44, Figure 2.

Figure 5 is a detailed sectional view through one side of the wringer frame, taken on line 55,- Figure 2.

Figures 6 and 7 are enlarged detailed sectional views through one side of the water board taken, respectively, on lines 6-6 and T7, Figure 1.

As illustrated, this wringer comprises a main supporting frame -1 having a substantially central lengthwise opening 2 therethrough from front to rear, forming lower and upper bars 3 and 4 and opposite end bars 5- and -6-, saidframe being divided vertically at 7+ through its longitudinal center to form op posite similar half sections which are preferably made of cast metal and subsequently bolted together face to face by clamping bolts 8.

The object in making the frame in sectlons is to not only facilitate casting and assembling in that the guide openings and recesses for the movable parts may be cast in the frame without extensive coring, but reduces to a minimum the amount of machine work necessary for receiving those parts, thereby greatly reducing the cost of production and increasing the output.

The lower bar 3 is provided with a vertical opening 9 therethrough from top to bottom and is provided with oppositely projecting downwardly inclined flanges 10 along the upper edge of its front and rear sides to partially guide the clothes. in their passage through the rollers in reverse directions, and to prevent, as far as possible, the winding of said clothes upon the lower roll.

The upright end bars -5- are provided in their inner sides with channels -11' merging at their upper ends with the adjacent ends of a similar channel 12' in the lower side of the upper bar 4- for reducing the weight of the castings and for other purposes hereinafter described.

A pair of rubber covered wringer rolls 13 and 14- are mounted in parallel relation within and upon the main supporting frame to extend lengthwise across the opening 2, the lower roller being provided with opposite end journals 15 supported upon bearing blocks 16 of oil saturated wood or other equivalent material, the upper roll being provided with endjournals l7 which are engaged by bearing blocks 18 similar to the block 16 except that they are arranged in reverse order. The journals 15 and 16 and relatively smaller portions of the adjacent ends of the rollers -13 and -1 t extend into the channels --1lof the corresponding upright end bars 5- and -6' so that the front and rear walls of said upright bars extend inwardly slightly beyond the adjacent ends of the enlarged portions of the rollers to form guards or shields 19 which deflect the clothes from the ends toward the center, andprevent them from coming in contact with the journal bearings 16 and -18- and also from wedging between the ends of the rollers and inner edges of the upright walls 5 and 6.

The bearing blocks -16 and 18 are movable vertically in the channels 11 of the upright bars 5 and -6-, the outer end walls of the opposite sections of the end bar 5 being closed across the adjacent ends of the journals -15 and 17 and bearings 16 and -18-, while the outer end walls of opposite sections of the upri ht bar--6 are slotted vertically along their meeting edges to receive the adjacent bearings 15- and 17 and permit vertical movement of the rollers.

The bearings 16 normally rest upon suitable seats -20-- at the lower ends of the channels 11- for the purpose of normally holding the lower roll 13- in a horizontal plane.

The upper roller 14 is free to move vertically, but is normally yieldingly held in engagement with the lower roller 13-- by means of a semi-elliptic leaf sprlingi -21 which is movable in the channel 12 of the upper bar -4-, and has its opposite ends engaged with the upper faces of the bearings --18, suitable means being provided for tensioning and releasing the spring at will.

As illustrated, this tensioning and releasing means comprises cooperative levers --22 and 23 and an adjusting screw -24-, said levers being pivoted, respectively, at -25- and 26 to and between the front and rear walls of the channel 12-- of the upper bar -4 at opposite sides of the screw -24, which is engaged in a threaded aperture -27 in the lever -22- and has its lower end engaged with the intermediate portion of a leaf spring 21-, and its upper end provided with a handle -28 by which it may be turned for varying the tension of the spring upon the bearings 18, and thereby producing a corresponding variation of pressure between the rollers.

These levers are movable in an opening 29- in the upper wall of the channel 12, and, when adjusted to produce the desired tension upon the spring 21-, their upper faces lie substantially coincident with the upper face of said top wall, while the screw projects a sufiicient distance above said wall to permit it to be easily operated by the handle 28.

The adjacent ends of the levers -22- and -23-- are recessed at -30 and meme? 31, respectively, to form shoulders -32 and 33 which are arranged so that the shoulder 38 projects into the recess 30-. and normally overlaps upon and engages the upper face of the shoulder -32-, the last named shoulder being normally extended into the recess 31-, and therefore directly under the shoulder 33--.

The overlapping or engaging, portions of the shoulders 32' and 33 lie directly over the pivot 26 so that the upward pressure of the shoulder 32 against the underside of the shoulder 33 as produced by the tension of the spring 21- is in a direct line nearly parallel with the axis of the screw, or in the direction of pressure of the central portion of the spring, thereby establishing a frictional lock between the meeting faces of said shoulders to hold both levers in their adjusted positions without extra locking means.

The lever -23- extends from its shoulder -33- some distance beyond the opposite side of the pivot 26 where it is provided with a hand piece 34-- projecting a short distance above the top of the bar 4-- to permit it to be engaged by the hand for depressing said lever to the position shown by dotted lines, and thereby releasing the lever --22- and the tension of the spring 21-, which also releases the pressure of the rolls one upon the other.

When readjusting the tension of the spring, the screw. 24- may be turned upwardly a sufiicient distance to allow the levers 22 and 23-- to be again interlocked with each other, whereupon, the screw may be adjusted to produce a desired tension upon the spring and corresponding pressure between the rollers. v

The front and rear walls of the channeled bar preferably extend downwardly a sufficient distance to cover the edges of the spring --21, and serve as guard shields to reduce the liability or danger of injury to the hands of the operator by being caught between the spring and lower edges of the bar 4 when the spring is released.

The side bars 5-- and 6 extend downwardly some distance below the lower lengthwise bar +-3 to form supporting guides --35 for a transversely movable water board or table -37, which consists, in this instance, of a pair of similar side rails 38, a sheet metal plate 39- secured to the side rails and holding them in fixed spaced relation, and front and rear rollers -40-- journalled at their ends upon the ends of the Side rails -38.

The marginal edges of the sheet metal plate 39- are preferably bent downward at 4l for reenforc-ing purposes, the opposite sides of said plate being seated in ,recesses 42 in the inner faces of the side rails 38 and are firmly held in this position by screws 43 and clamping bars -44., which latter engage theinner faces of the adjacent downturned edges of the to permit the water board to be removed gua and replaced at will. I

The slots 45-- in the side rails 38 extend throughout the greater portion of the length of said rails to permit the water board to be adjusted transversely of and under the rollers -13--- and 14 and l tilted rearwardly or forwardly as it [is moved to corresponding extreme positions, or it may be locked in certain positions by means of a lockin bolt 4' which is movable in one of t e extensions, as -35, against the action of a spring.-48,, and is adapted to engage in one of a series of apertures 49, in the adjacent rail -38-.

The purpose of' the water board is to support and guide the clothes some distance beyond the rollers in transit there-' through in either direction, or'may be used to catch the drip of water from the rolls and deflect it back into the Washing vat, particularly, when the wringer is used in connection with a washing machine as shown in my pending application, Ser. No. 355,515, filed Jan. 31, 1920. e

In the operation of the spring releasing mechanism, assuming that the levers 22 and 23 are interlocked withleach other, and that the spring is placed under tension by the adjustment of the screw 24, then, if desired to instantly, release the pressure upon the rollers, as for example in case of accident or the accumulation of an excessive thickness of plothing between said rollers, it is simply necessary to press downwardly upon the hand piece 34', which disengages the lever -23- from the lever 22, thereby releasing the spring, which, by its distension throws the lever 22 and its screw 24 to the position shown by dotted lines, thereby releasing the pressure upon the rollers.

What I claim is:

1. In a wringer of the character described, the combination of a frame having an upper lengthwise bar and upright end bars, the upper bar having a lengthwise channel in its lower side, bearings movable vertically in the upright end bars, lower and upper rollers journaled in said bearings, an upwardly arched leaf spring extending lengthwise of and within the channel andhavingits ends engaged with the bearings for the upper roller, a lever pivoted to the upper bar to swing vertically toward and from the spring and provided with a threaded aperture, means operable at will into and out of engagement with the lever for locking and releasing the same, and a screw engaged in the threaded aperture of said lever for adjusting the tension of the spring.

2. In a wringer of the character described, the combination of a frame having an upper lengthwise bar and opposite upright en bars, said upper bar having a lengthwise channel in its lower side, journal bearings inthe end bars, lower and upper rollers having their ends journaled in said bearings, the bearings for the upper roller be ing movable vertically, an upwardly arched eaf spring extending lengthwise of said channel and having its ends engaged with the bearingsvfor the upper roller, a lever pivoted to the upper frame bar to swing vertically toward and from the spring and provided with a threaded opening, a screw engaged in said opening for engaging the central portion of the spring and tensioning the same, and Ya detent pivoted to the upper bar to swing about a horizontal axis into and out of holding engagement with said lever.

3'. In a wring-er, the combination of a frame,-journal bearings mounted on opposite ends of the frame, rollers journaled in said bearings one above the other, an upwardly arched bow-spring having its ends engaged with the upper bearings, a lever pivoted to the frame above the spring to swing toward and from said spring, a screw mounted on and movable. with said lever toward and from the spring, and a detent pivoted to the frame t3 swing about a horizontal axis into and out of engagement with the lever, said lever and detent' engaging each other in substantially the same vertical plane as and above the pivot of the detent. e V a 4. In combination in a device of the class described, a pair of pressure rolls, means for supporting one of said rolls for movement toward and 'from the other, a bow spring for maintaining said movable roll normally in contact with the other roll, an adjustable screw normally engaging "the middle portion of said spring, a plvoted 1 manually depressible member for disengagsaid latch from the tooth.
