SAFETY FEEDING DEVICE FORULOTHES WRINGERS.

Application filed- April 26, 1924. Serial No. 709,107.

Power operated clothes wringers have attained great popularity in household laundries, and are now in general use. Feeding the fabrics between the compression rolls of such wringers is a very particular operation and is frequently attended with injury to the fingers and hand of the operator, due to being caught and drawn between the rolls, despite her most watchful care. i

The purpose of thepresent invention is the production of a feeding device for attachment to clothes wringers which will obviate the liability of the fingers of the operator being caught between the rolls, such feeding device being so-formed as to recelve the fabric and carry itto a point where it Will have frictional engagement with the rolls and be drawn between them in the rotation of the latter. i The feeding device is embodied in a pivoted bar which is provided on its" forward side with an elongated Wedge-shaped por tion, for entering the fabric between the rollers, and on its tapering sldcs with fixed protuberances which latter are designed to support the fabric somewhat clear'ofthe bar, so

that the fabric may be drawn between the rolls without dragging, thus greatly facilitating'the movement-of the wet fabric over the bar without material frictional resistance. Also it isthe function of the said protuberances, by engagement with the rolls, to restrict the movement of the wedge-shaped portion-into the space between the rolls.

The novel features of the invention will now be particularly described, and then pointed out in the appended claims.

In the consideration of this specification, reference is to be had to the accompanying drawing which shows a simple constructional form in which my invention has been embodied. In such drawing:

plane which extends between the rolls of the wringer, and showing the manner of the attachment of my improved safety feeding device to the frame, the latter being transversely sectioned. I v

Fig. 2 is a vertical sectional view, enlarged, on the line 22, Fig. 1, looking in the direction of the arrows, and showing the manner in which my improved device operates.

Fig. 3 is a view in front elevation of the central section of the bar embodied in the construction of my feeding device, and showing the'wedge-shaped formation of the fabric feeding element, together with the arrangement ofthe fixed protuberances on the tapering sides thereof which provide a clearance between the bar and the fabric resting thereon. v i In the drawing, the numerals 1O and'll indicate the standards or a clothes wringing machine, in which standards the shafts '12 and 13-of the rolls 14: and 15, are journalled in themanner usual to constructions of this kind. v I

A bracket 16 is attached tothe standard 10, such bracket receiving and supporting pivotally one end of a feeding bar 17 the which is 'adaptedto enter theopen space existing at the front side of the rolls and in the plane of their peripheral contact. In

the movement of the bar 17 toward the'roll's,

the wedge-shaped projection 19 is designed to penetrate the said open space to an extent I that the tapering sides of the wedge will lie closely adjacent the surfaces of, the rolls, but not in contact therewith, so that the said wedge 1 cannot, accidentally or otherwise, exert a separating action upon the said rolls.

I achieve this restriction in the forward movement of the bar 17 by the provision upon the bar of means for engaging the rolls at points remote from the line of their Figure 1 is a plan view in the horizontal the manner hereinbefore described, they have the further important function bf su orting the fabric clear of contact with the sides of the wedge, so that the wet fabric, when grasped'by the rolls, may be drawn off the bar without drag 'ing over the sides thereof. Thus, the feeding ihove'iiint through the rolls is effected withoutimposing delicate fabrics to any unusual strains, so that danr age thereto is avoided. v

The bar 17 with the fixed, rounded pro-1 tuberances 20 is cast as a single piece, and

machining thereof for the reception of other adjunctive' parts is obviated. Preferably,

' the castingis ofalrminuni, but may be of any suitable material. It is advantageous that itbenon-corrosive. In the interest of lightness, 1 cast the wedge-shaped section with hollow rear portion, as indicated at 21; i construction very economical in cost, and nay easily be attached to any exist; ing machine.

Inoperation, the rolls are set in motion, and the bar 17 is swung outwardly from the rolls by one handof the operator.- The wet fabric from the tubis then passed vertically into the widened space between the rolls and the bar, laid overthe latter as thehar is moved toward the rolls. a When the-fabric contacts with-the rolls under the pressure exerted the wedge-shaped portion of the bar, the frictional engagement. of the rolls with the fabric will draw the latter from the banana pass it through the rolls, whereby the moistureis expressed from the fabric.

The Wet fabric will not cling to or drag over the sides of the wedgeshaped portion of the bar, for the fined protuberances 20 create a clearance which facilitates the movement of the fabric; The fingers of the operator are never near the rolls, and consequently liability to i jm-y r warded; i

Having thus described my invention, What I claim and desire to secure by Letters Pateiit of the Unitdstates, is:

1. As a new article of manufacture, a safety feeding device for clothes wringers constitutedas abar provided with means for pivotally supporting it at one end, and l'rand-engagingmeansat the other, whereby the said bar may: be swung in a horizontal plane upon itspivotal support, the said bar being provided upon its forward side with a wedge-shaped portion, for entering the fabric between; the rollers, and the tapering sidesjof which wedge-shaped portion are provided with fined protuberance-s, which latter support thefabric clear of the wedgeshapedport-ion; to facilitate its passage thereoverpandalso prevent engagement of the wedge-sha ed portion with the rollers.

,2. Asafl new article of manufacture, a safetyfeeding device, for clothes wringers constituted as a bar provided with means for pivotally supporting it at oneend, Whereby the said bar maybe swung in'a horizon-, tal plane upon its pivotal support, the said bar being provided upon its forward side With a wedge-shaped portion, for entering the fabric between the rollers,an'(l the tapering sides ofwhichwedge shaped portion are provided with fixed H protuberances, which latter support the'fabric clear of thewedgeshaped portionto facilitate itspassage thereover, and'alsoprevent engagement of the wedge-shaped portion with the rollers.

In testimony whereof, Ihhave-signed my name atMilwaukee, this 21st day of April,
