' SAFETY DEVICE FOR WRINGERS.

' Application filed July 14, 1921. Serial No. 484,681.

F. SNYDER,

my invention are to provide in clothes,

wringers a safety device to eliminate the danger of the operator getting his fingers caught between the rolls further the provision of a manually operated attachment for wringer rolls in the form of a fabric guide having, preferably, a' pivotal connection with the wringer frame so that the guide can be manually shifted from and toward the bite of the. rolls and instantly withdrawn in case of over-feeding, in which the guide is adapted in inward position to projectinto the space between the peripheries of the rolls opposite the bite thereof and preferably substantially into contact with a roll, and no closer, whereby to cause the fabric to be grabbed by the rolls with,

out drawing the guide along with it; further the provision of such a device which is constructed and arranged to be quickly attached to either side of the 'wringer rolls; further in the provision of-fabric guiding means adapted to automatically return to its normal position removed from the rolls after the fabrics have passed therefrom to the wringer so as to be in position to receive a new batch; further in the provision of a guiding means adapted to beheld in operative position adjacent the bite of the rolls due to the dragging of the fabrics passing over the guiding means'as they are passing through the rolls, further in providing fabric guiding or supporting means constructed and arranged to be positioned adjacent the bite between the rolls to feed the fabrics theretoand to be shifted to a position removed'therefrom to receive a fresh supply of fabrics, said guiding means being adapted to substantially shield the bite of the rolls when infabric receiving wrapped around the rolls; further to prevent. buttons from tearing off or becoming broken While the article carrying the same is being'fed through the wringer; further to provide a safety device-of improved construction, and one that can be readily transferred from one side of the machine to the other; further to produce a safety device of maximum simplicity, efficiency, economy and ease of operation, and such further objects, advanta es and capabilities as will later more fuldy appear.

My invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawings, and while I have shown therein a preferred embodiment I desire it to be understood that the same is susceptible of modification and change, without departing from the spirit of my invention.

In the drawings Fig. 1 is a side elevation of a wringer having my improved safety device attached thereto.

Fig. 2 is a vertical transverse section on a line 2-2 of Fig. 1. v

Fig. 3 is a perspective view looking toward the under side of the safety device.

Referring to the drawings, my improved safety device isdesignated generally at A, and comprises the clothes support or guiding means 1, which at its upper forward side when in the position shown in Figs. 1 and 2, is preferably fiat, as shown at 2, which fiat portion merges into the downwardly and outwardly curved face 3, terminating. in the lower edge 4. Fixed adjacent the respective ends of support or guide 1, are the downwardly extending brackets 5 and 6, the latter of which at its inner end is formed-with'the opening 7, adapted to pivotally receive pin 8, -carried .by the side an opening 12, which lies opposite the re-- cess or notch formed by the cutaway por-- tion 10. The opposite side portion 13 of the wringer frame carries an outstanding I pin 14, adapted to pass through opening 12, which in conjunction with opening 7 and the wringer frame for a purpose herelna pin 8 pivotally mount the safety device uptzn r more fully set forth. Adjacent the end of permit removal of safety device A from t e wringer, which may be eflected by first releasing the same from pin 14 in a manner just described, and then withdrawing the same endwise from pin 8. v

To permit use of the safety device .on either side of the wringer, the corresponding side portions of the opposite side are provided with similar pins to be received in openings 7 and 12in a manner which will be readily understood from the above.

As noted in Fig. 1, the support; or guide 1 is formed at its opposite ends with the upstanding flanges 16, 17, which are inclined away from-each other toward their outer edges, and which extend downwardly to edge 4. In addition, the guide 1 is provided with shoulders 17" which limit the inner movement or position of the lip 18 of the guide 1 relatively to the bite of the rolls. When in fabric feeding position as shown in Figs. 1 and 2, the tip or inner edge 18 of the fabric guide 1 will lie in the space hetween the peripheries of the rolls opposite the .bite thereof. and will be substantially touching more or less or just out of contact with the lower roll 19 on a line a slight d stance outwardly from the meeting llne or bite of the rolls.-

In the operation of my improved safety device, it will normally stand away from .therolls withthe lower edge of brackets 5 and 6 contacting face 21 of the drain board, or such other part of the wringer frame as may be presented in the different makes of wringers. Assuming that the article to bewrung is of fair size, it will be thrown with its edge slightly across edge 18 of support or guide 1, and support or guide 1 will then be manually swung upwardly to bring it into the, position-shown in Fig. 2, at which time the adjacent edge of the garment will be picked up by the lower roll, and immedi-' ately carried between therolls, without the necessity of the operators' hand coming any closer to the rolls than lower edge 40f sup port orguide 1, which edge he maygrasp in rotating the support or guide into operative position. It is ofimportance to note that when theedge of the garment is thrown across edge 18, it will be passed between the rolls, with its edge underlapped, which I have found. prevents any possibility of the garment becoming wrapped around the wringer rolls. lnaddition, it must be evident that reason of the fact that the attaehinent free to-he manually swung away from nthe rolls it IS instantly releasable in and thus prevent the lip from being drawn into the bite of the rolls along with the fabric. Small articles, such as handkerchiefs, and the like, may be laid on to the upper surface of a larger article which is passing over the guiding means 1, and thus be carried between therolls, without the necessity, for example, of laying the article any closer to the rolls than upon curved face 3, the articles being thus carried between the rolls upon the larger article being wrung, thus again avoiding any possibility of the smaller articles becoming wrapped around the wringer rolls. The outer portion 22 of the drain board on the opposite side of the machine, will serve as a guide toguide the wrung clothes into a basket, ifvdesired, without the necessity of the operator receiving the articles in his hand from the outwardly moving side of the rolls. In passing over guiding means 1, buttons, and the like, will be caused to lie flat, and thus will go between edge 4, or grasp any other of the lower portions of the safety device desired, it will be readily seen that the fingers of .the operator may be kept well away from the wringer rolls, and any liability of the fingers bemg caught therebetweenwill be entirely eliminated'. While I have illustrated the spring arm 11 as one means for-removing the safety device from pins 8 and 14, I.wish it understood that other means may be used toiaccomplish this purpose, without departhig from the spirit of my invention. Due to the free pivotal mounting of th supporting or guiding means on the pins 1-4 and to the disposition of the center of weight of the guiding means to the rear of the pin 14 and the location of the presenting edge. 18 adjacentthe bite of the wringer cylinders,

it is manifest that whenthe clothes and other fabrics are being pulled forwardly between the wringer rolls, as they drag over the supporting means, the dragging action 1 will maintain the latter inthe position illustrated in Fig. 2, of the drawings, and that upon the completion of the feed of the fabric through the rolls, the safety device, will automatically fall by gravity against drain I board 21 (or 22, depending upon which side of the wringer the device is located) thus presenting edge 18 in an upward and well away from the wringer rol may then be passed between the rolls by merely rotating table 1 to bring edge 18 into position p s to receive a further article to be wrung, which that due to the curvilinear surface of the guiding means and the disposition of its pivotal axis at 14, the upper edge 18 of the guiding means will move in a substantially arcuzontal line of fabric feed into a position (when the lower end of the guide 3 contacts with drain board 21) such that the guiding means substantially shields or guards the opening between the rolls. 7 V j 1 Having now described my invention,

1. In a safety device'for wringer rolls, a for supporting articles to be wrung and hating arms at its respective ends, pivot pins on the wringer frame, said arms having openings near the free ends thereof for mounting on said pins to permit the guidingmeans to be swung toward or from the wringer rolls, and means adjacent the. opening in one of said arms to permit easy removal of the same that the safety device may be from its pin, so transferred to the other side of the wringer, when desired.

2. In a safety device for wringers, 'a movable guiding means for supporting articles guiding means, said flanges to be wrung and comprising a front edge adapted to receive the edge of an article to be wrung, said guiding means being movably mounted. on the wringer frame to bring said front edgeadjacent the line of contact of the two wringer rolls to cause feeding engageme ntof saidarticles bysaid rolls, and an upstanding flange on-each er 1'd of said being inclined outwardly away from each other to guide said articles between the rolls. 7

3. In combination, a wringer frame com prising spaced side port-ions, and having a pair of rolls, a pin mounted in each of said side portions and extending toward each I posltioned opposite the bite of the rolls, said other, a guiding means having a downwardly extending bracket adjacent each end, one of thereon,

said brackets having an'opening in its free end to rotatably receivev its corresponding pin, the other notch formed in its free end, and a keeper adjacent said notch, and a resilient arm fixed, bracket and having in its free end an opening tofall opposite said notch, whereby .board respectively. ate path upwardly across the normal horiof saidv brackets having a.

said bracket, said guiding" and arranged to. have its upper. and lower ends move into substantial contact with the upper periphery of the lower roll adjacent the bite between the upper and lower rolls and with the drain 5. A manually operated fabric feeding at taehment for laundry wringer rolls, comprising in combination with a support on each side of the wringer frame, a fabric guide havinga quick detachable pivotal connection whereby said guide can be readily mounted on either side of the rolls to be swung freely by hand from a position removed from said rolls to a fabric feeding position opposite the bite of the rolls and to be instantly releasable in said latter position to move away from said rolls to relieve feeding of the fabric between the rolls, said guide having a forwardly extending fabric receivmg lip adapted to project into the space between the opposed peripheries of the rolls opposite the bite of the rolls and substantially into contact with a roll periphery whereby on rotation of the-rolls said fabric 15 grabbed by said ,rolls and fed therebetween, said guide having means for preventmg said lip from being drawn into the bite of the rolls along with said fabric.

6. The combination with wringer rolls, of a fabric receiving and supporting member mounted contiguous to said rolls so as to be movable toward and from the'rolls, said member having a free and unobstructed surface on which thefabric is adapted to be p0- sitioned when said member is removedfrom the rolls and over which said fabric may be freely drawn during fabric feeding, said member having a projecting lip over which the fabric maybe draped so that it will be movable with said member toward said rolls, and means for arresting movement of said member toward said rolls when said lip is the class described, the

said rolls, said guide providing a free and unobstructed surface on which said fabric is adapted to be draped when in position away from the rolls and over which said fabric will be freely dragged when drawn by the rolls, said guide having a forwardly projectin'g unobstructed lip over which said fabric is adapted to hang, which lip is adapted to be positioned close to the bite of the rolls and substantially touch one of said rolls, and means to positivelvlimit the inward movement of said guide and thereby the inner- I most position of said lip to prevent said lip from being drawn into the bite of the rolls together with the fabric during its feeding movement.

8. The combination With Wringer rolls, of an arcuate fabric receiving and sup orting member pivotally mounted substantially at toward said rolls'andmeans for arresting movement of said member toward said rolls when said lip is positioned opposite to the bite of the rolls, said member constituting the sole means for bringing-the fabric-up to the rolls and being movable towards said rolls by manual means alone, said member being so mounted as to automatically remove it from said rolls after the fabric is disengaged therefrom.

In witness whereof, I hereunto subscribe my name to this s ecification.
