This invention relates to safety devices for feeding material to the squeeze rolls of wash Wringers and the like.

The main objects of my invention are to preclude the possibility of the hands being caught between and drawn into the squeeze rolls of wringers;- and to attain this end through provision of a simple, inexpensive and easily operated device forthe purpose, '0 capable of ready application to all standard types of wringers. 1 her objects and attend-ant advantages of this mvention will appear from the detailed description following when taken in connec-- 5 tion with the attached drawings, whereof Fig. I is a perspective View of a conventional type of wringer equipped with my improved safety feed, the latter being shown in re tracted or loading position.

30 Fig. II is a cross sectional elevation of the wringer with the parts of the safety feed positioned to correspond with Fig. I.

Fig. III is a perspective view, similar to Fig. I, showing the safety feed in the ad- 2'5 vanced or feeding position; and,

Fig. IV is a cross section like Fig. II, but with the parts of the safety feed positioned as in Fig. III.

From these illustrations it will be seen that the safety feed of my invention comprises a feedmember '10, the same being movable, as hereinafter noted, from the retracted or loadin position of Figs. I and II, to the ad- Vance or feeding position of Figs. III and IV in presenting the material M, which is to be wrung, at the bight of the companion squeeze rolls R, R of the wringer, comprehensively indicated by the letter 'W. As shown, the feed member embodies a hori zontal bar 11 which is angular in cross section, and, beneath the forward edge .of said bar is .a freely revolving auxiliary progressing roller 12. At 13, the bar 11 has pivotal connection with the ppe-r ends ofsupporting arms 14 which are fulcrumed at the :bottom to brackets 15, secured to the verticals of the wringer frame F at one side by screws 16. The feed member 10 ismoreover formed with upwardly reaching extremities 17 which extend forward somewhat at the top as at 17a and carry lateral projections 18 arranged to engage vertical slots 19 in ears 20 of the brackets 15; Rea'rward' ofthe projections 18, the extremities -17 of the feed' member 10 afford pivotal conneetionfor' a hanger 21 with drooping side arms 22 integrally joined by a transverse rod 23 whereof the ends nor- V mally rest on the forward extensions 17a ofsaid extremities. Suspended from the hanger 21 is a finger guard 25 constituting a shield across the fr nt of the squeeze rolls R','R of'the wringer W. The outward swing of the, feed member 10 is limited, as shown in Fi s. I and II, through contact of the projections 18 on the extremities 17 with the bot- 85 toms of the slots 19 in the brackets 15; while the inward swing'i-s limited through engagement of stops'14a on the'arms14 with the wringer frame asshown in ig'. IV.

The operation of the device is as follows: 7

' Withthe feed member 10 retracted as in F igs.

I and I theleading end of the material M is laid on the bar lljsoa's to overlap the auxiliary progressing roller "12." The feed member 10 isthen moved inward by hand to the position of Figs. III and IV with the result that the lapping end of the material M is pressed, by the auxiliary progressing roller 12 against the lower squeeze roll R of the wringer W. Through motion thereby'induced in the roller 12 the'fold of the material M is advanced "so as to be caught in the bight between the roll It and its companion R. In this connection it is to be particularly noted that the feedmember 1-0 is maintained under the influence-of gravity both in the retracted or loadingpositionand the advanced or feeding positionby virtue of the swing of the supporting arms 14 to opposite sides oft/he vertical or dead center. It is moreover'tobe noted that through proportioning of the various interconnections involved, the finger guard 25 is ordinarily littedjust sufficiently to clear the material it is presented to thesq'ueeze rollsR, incident'to the inward swing ofthle feed member 10'. I

When necessary, access may be had to the squeeze rolls R E of the wringer W' from the front by lifting the hanger 21,- as shown in dot-and dash "linesin 'Fi-g'. II, thereby to tween the lugs 27 and parallel lugs 29 be neath, said slots being open at the back as indicated at 30. Withthe projections 26 thus 3 freed, the guard top of its pivots, 21 in turn swung rearward in a manner entirely obvious from Fig. 11.

' The wringer chosen for the purpose of illustration hereinjis. of a reversible type comcan be swung over the mon in connection with modern washing machines, it being mounted to swing horizontally about a column O and provided with a drainchute S which is oppositely tiltable as shown in dQt-and-dashl-ines in Fig- II. To enable use ofthe safety feed 10 in thereverse position of the wringer'W if desired, the other side of thewringer frame maybe drilled and tapped to take the bracket screws 16 incident to transposal ofthe feeddevice to that side of said .frame. j I I 7 Having thus describ d my IlIlVGIIi' lOIM'I claim; a g1 1 A safety feed for. wringers having squeeze rolls comprising a horizontally-pivoted gravity-influenced feed member with an associatedfreely-rotatable roller for presenting material tobe wrung at the bight of the squeeze rolls, afinger. guard .for shielding the rolls, and means operatively coaordinating said guard with the feed member-for inducec movement to clear the material concurrent with its presentation to the wringer squeeze rollspf 1 2.
