WRINGER SAFETY FEEDER Filed CCt. 3l, 1927 Patented Apr. 7, 1931 UNITED STATES 'PATENT oFFlcE WILLIAM H. BOWDN, OF NEWTON, IOWA, ASSIGNOB TO THE MAYTAG COMPANY, OF NEWTON, IOWA, A CORPORATION OF DELAWARE WRINGER SAFETY FEEDER Application led October 31. 1927. Serial No. 229,979.

provide a wringer equipped with a feed an'd aving parts so constructed and arran ed that the said device can be easily and rea ily adjusted fromfone side to the other of the wringer.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various 'parts of my wringer safety feeder, whereby 2 the objects*l contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanymg drawings, in which:

Figure 1 is a top or plan view of a wringer equipped with a safet feeder embodying my invention, one end of t e wringer being shown in horizontal cross section.

Figure 2 is a'detail, sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a detail, sectional view taken on the line 3-3 of Figure 1; and

Figure 4 is an enlarged, detail, sectional view illustrating the means for locking the spindles in their notches or slots.

In the. accompanying drawings, I have shown a wringer which may be of the type now commonly used, having the lower lon itudinal member indicated in the drawin s y the reference numeral 10 and the space opposite end members 12.

A lower wringer roll 14 has a shaft 15 journaled in the end members 12 and provided at' one end with gearing mechanism 16, through which rotation maybe imparted to the roll 14.

Pivoted. to the frame members 12 at the top thereof are the arms 18. The arms 18 are connected by a cover strap 20.

A release member in the form of a connecting cover 22 has at its ends the arms or fingers 24 pivoted to the arms .18 near their free ends. The release 22 coacts with hook members 26 for locking the upper wringer roll 28 in position. l

The wringer roll 28 has the shaft 30 journaled in the arms 18.

The structure above described is standard and forms no part of my present invention, except that the upper 'wringer roll 28 of the wringer used with my safety feeder, should .be capable of being moved upwardlyfzand substant'ially away from the roll 14.i

In Figure 3, I have shown in dotted lines the upper roll swing upwardly and out of the 'Xhe wringer is also'provided at each end and near its opposite sides with lu s 32, having slots 34 in their upper ends. hese lugs are for supporting the feeder.

-My improved feeder comprises a channelshaped member 36 having the inset end walls 38. The walls 38 have near their upper and lower parts projecting spindles 40.

The two lower spindles 40 are dropped into the slots 34 of the lugs 32 at one side of the 75 wringer. Each end member 38 has midway between its spindles 40 a lug 42, extending lolgitldinally outwardly. (See Figures 1 an 3.

In order to hold the spindles 40 in the slots 34, I have provided in the lugs 32, spring actuated pins 60 with rounded inner ends, past which the spindles 40 can be forced. The pins 60 serve to hold the spindles 40 in place, 85 as illustrated for instance 1n Figure 4, against accidental removal. y

For connectin the feed with the lower wringer roll, an thus providing means for actuating the feeder, I provide the following means:

On the shaft 15 of the lower wringer roll 14 at each end of the roll is fixed an eccentric disc 44. A band or ring 46 is received on the disc 44 and has a projecting arm 48 terminating in the reduced portion 50, which is slidablye'xtended through the lug 42, as shown in Figure 1.

On the reduced portion 50 is a coil spring 52, which is held against the lug a cotter pin or the like 54, extended through the outer end of the reduced portion 52.

Referring now to Figure 3, it will be seen that when the lower wringer roll is rotated, the eccentric disc 44 will give to the band 46 and the arm 48 a reciprocating motion. This will be transmitted to the lugs 42 and thus to the wr'inger feeder.

The wrihger feeder -will thus be rocked upon its lower spindles 40 from its position shown in Figure 3 to the position shown in Figure 2 and back.

In feeding the garments to the wringer, the garments are laid over the upper part of the member 36, when that member is at its outer position, as illustrated in Figure 3. Then as the roll 14 rotates, the feeder will be rocked to the position shown in Figure 2, where the upper part thereof will stand in the position shown in Figure 2 for feeding 'the garments to the wringer rolls.

When the feeder is rocked back to the positionshown in Figure 3, another garment can be laid on it to be fed to the wringer.

If it is desired to change the feeder from one side of the wringer to thev other, the upper wringer roll is released and swung upwardly out of the way by the standard mechanism, and the feeder is swung upwardly across and part way around the lower wringer roll, from its full line position show n in Figure 3 to its dotted line position shown in that figure.

The spindles 40, which were the upper spindles when the feeder was on the left side of the wringer, as shown in Figure 3, will after the change be received in the slots 34 of the right-hand lugs 32, and when the upper roller is again replaced in position as shown in Figure 3, the feeder can b e used on the right-hand side of the wringer.

It will be seen that there is thus provided a feeder, the upper part of which rocks or reciprocates toward or from the line between the two wringer rolls.

The feeder is actuated by the operation of the wringer rolls themselves. It may be conveniently swung from one side of the w ringer to the other.

The importance of awringer safety feeder will be readily seen. It frequently occurs that during the wringing operation. the hand of the operator is caught in the wringer roll and seriously crushed or mangled. This is a danger which becomes more important on account of the fact that wringers are now operated by power.

Wlith a device of the kind shown here, the danger of catching the operators fingers or hand is very largely eliminated` I have in the drawings herewith illustrated one form in which my wringer safety feeder may be embodied. It is not my purpose to limit myself to that particular form of feeder, nor to the particular mounting or manner of operation herein set forth, but it is my purpose to cover by my claims any modified forms of structure or use of me-y chanical euivalents, which may be reason- .3 1
