SAFETY DEViCE FOR FEEDING criorrms T0 wnmenas.

Application am February e, 1926. Serial No. 36,600.

.This invention relates to attachments for clothes wringers and particularly to an 1mproved safety device for quickly and automatically turning off the power when a hand or other large object 1s moved a cer' tain distance toward the rollers.

Another object of the invention is to provide'an improved safety attachment which is an improvement over my prior Patent No.

1,537 ,864, wherein the power to the motor is automatically cut off instead of an actuation of a clutch for disconnecting the power.

A further; object of the invention is to provide an improve safety device for wringers in which scrapers are provided to prevent the clothes passing through the wringer from adhering to the rollers thereof, the terms in which the claims are expressed.

In the accompanying drawings- Figure 1 is a side view of a wringer 'with a safety device embodying the invention shown applied thereto. a

Figure 2 is a view similar to Figure but showing only part of a wringer and lllustrating the safety device in an operated position'.

Figure 8 is a. detail fragmentary view.

similar to the structure shown at the. left in Figure 4' but illustrating a modified arrangement of scraper.

Inapplying an embodiment of the invention to a wringer, it will be noted thatthe saine may be applied to any of thewringers now in common use where they are driven by electric motor. It will be understood that the detail structures of the wringer and motor form no part of the present inven-. tion.

Referring to the accompanying drawings by numerals, 1 indicates a support'of any desired kind. on which a wringer 2 is mounted. The wringer 2v is provided with brackets 3 which may be specially secured thereto by screws or otherwise and which fit into notches 4 in the extensions 5 on the side bars of frame 6. The frame 6 is provided with two side bars constructed as shown in Figures 1 and 2 and with suitable connecting and bracing bars 7 held in place by suitable nuts.

It will be noted'from Figure 4 that nuts are provided on the bar 7 for spacing'the sidebars of frame, 6. Rollers 8 and 9 are 12 arranged in enlargements 13 .on t e'respective side bars of frame 6; These springs act on journal blocks 13 (Figure 7 which press against the shaft 14 supporting the roller 8. A cross bar 15 isconnected in 'any suitable manner withthe extensions 5, said cross bar supporting a scraper 16 and a.- guiding plate 17. The scraper. 16 may be made of a combination of rubber and canvas or other desired material and acts to in a certaln sense, scrape or prevent clothes from following the belt 11 around .roller 9. This rotatably mounted on. the frame 6, roller 8 scraper insures all of the clothes passing j over belt 11 engaging the plate 17 and then the roller 18 of the wringer 2. The plate 17,

' together with the scraper 16, acts as abridging structure for bridging the space between the rollers 9 and'18;

22. It' will be noted that there are twof arms 1 21 and two arms 22 and these'respectixte are bolted or otherwise secured to the respective metallic holders 23 and 24 'gripping the scrapers Hand 20; The arms 21 are In order'to prevent thin pieces of clothes preferably pivotally held in place by the respective ,pivotal. pins 25' which holdthe swinging frame 26 on an extension 27 of frame 6. A retractile spring 28 is connected to frame 6 for each of the arms 21 and at one end is connected to these'arms for normally holding the scraper 19 against theroller 18. Each of the arms21 is also provided with a forwardly extending portion 29 .0 (Figure 2) formed with a bent over section 30 adapted to be engagedby the thumb when it is desired to raise the scraper 19 oil the roller 18'. The arms 22 are yieldingly held against the roller 18 by springs 31 connect- I -ed to the respective arms and to the cross bar 15. 1 Each of the arms 22 is provided with a forwardly extending section 32 which ma be engaged by the hand of the operator an moved upwardly for swinging the scraper 20 away from-roller 18. It will thus be seen that as the clothes are fed through the wringer, the scrapers 19 and 20 continual- 1y function to prevent any of the clothes from adhering to the rollers and, consequently,

causing the rollers to continually function in a desirable manner.

In regard to the frame 26, it will be noted that the same is provided with a pair of side bars 33 and one of these side bars is formed with an extension 34 through which the rod ,35 loosely extends, said rod having a nut 36 I acting as an abutment and also an adjustable stop 37 vfor confining the spring 38 between the abutment and the enlargement .34.

The frame33 is supplied with a roller 39 which rests on the belt 11 when no clothes are being fed into the wringer. Asthe clothes are fed in, this roller is raised. more or less according to'the thickness of the, clothes.

40 Theraising of the roller 39 swings frame 26 more or less and, consequently, compresses spring 38 to a certain extent. If a large object, as for instance, a hand, is forced beneath roller 39 as shown in Figure 2, spring 38 will be so compressed as to swing the lever 40 sufficiently to cause the extension 41 to engage the push buttoii 42 for throwing the switch 43 to an open position. 1 This will shut off the power to the wringer and, consequently,,the hand willnot be injured as thepower is shut off before it can reach the rollers 18 and 18. It will be noted that the wringer 2' is adapted to be driven by anelectricmotor of any desired kind and the motor is adapted tobe connected to the wringer in any desired way but the circuit of themotor must pass through the switch 43. When the hand or large object has been removed from the posi ion shownm'Figure 2, the end'44 of abutment 42 is pressed and theswi-tch again closed. If it shouldbe desiredto wring com- Earatively jthick "articles, fas forlfinstance,

lankets, the frame 26 would naturally be elevated to such an extent as tooccasionally 1hthrowy ofi the p er; which would be objecears or a chain as shown in Figures toa position" across th tionable. To prevent'this" action, a vertical ly sliding plate/45 is provided, said platebeing looselycarried by theiipright 46 which also carries a switch 43 and which is secured in any desired manner to the extension 27 of frame 6. As thethickyclothes are being forced into the machine and the operator observes that the swit'ch 43 -lis about to be opened, plate 45 ,is raised so that the sli ht movement of the" pin 42 caused by the first -movement of lever'40will cause the pin to press against plate 8 45' and hold thejsarne; in place as long as the" thick article is fbeln'g assed throughgth e ,w'ringer." As' soon asthe thick article has pa'ssedthroug'hthe wringer, frame 26 will imrne diate'lyfdrop to -"1 W?!" position which will relieve the pressure on thelabutment42 and the plate 45 willfdrop to the position shown; in Figure 2 so that, the safety device againinlfunctlon gP" sition. g It will be understoodthat the 'roll'er i9 may be driven from a wringer -in a'nydesired manner, as for instance,iby 'atraili' o;

dud 4. When either a chain or trai'n 'of gears is used, preferably ajsuitable housing.- is used for covering the parts. It will also be evident that the scrapers 19 and 2Qmay be connected tofa 'stationarypart of the 95 wringer instead-f'of to the 'framefti as'illus trated in Figure 8. 7 From this figure it"willbe noted that the scrapers function to re: move the clothes from the rollers but are pivotally mounted on the wr'inger; 2 held in operative positionffby suitabl'e springs. In driving "the; beltfth'e same may be driven b anre entimeansas-heretorore described but undersome circumstances it may be desirable to drive the belt throu h 108 the use of special g ars oricogwheels mes ing with the special gears now in useon all wringers. 'i'i'sin *gmsor this k-ind orin using the chain riveas'shown infthe drawings, the device couldb'e shifted from" one side to the'otherso"as to*be use "an either'side ofthedwringeri-" WhatI claim is: 1.
