HENRY LoUfSMoRIN, or SPRINGFIELD, MASSACHUSETTS.'

SAFETY FEED AND AUTOMATIC STOP FOR WRINGERS.

Application filed April 9,

To all whom 'it may concern.'

Be it known that I, HENRY I1. MonrN, a citizen of the United States, and .a resident of Springfield, in the county of I-Ia'mpden and State of Massachusetts, have invented a new and Improved Safety Feed and Automatic Stop for VVringers, of which the following is a full, clear, and exact description.

This invention relates to attachments for wringers and particularly to an improved safety feed and automatic stop wherein articles fed to the wringer may be properly directed while the directing means acts also. to throw off the power in case the same is moved to a predetermined point.

Another object of the invention is to prof vide 'a safety feed and automatic stop for wringers wherein'the feed mechanism when moved to a predetermined position, will actuate a clutch for throwing off the power to both the wringer and the feed. A

A still further object of the invention is to provide a. simplified form of combined throw off mechanism and feed whereby when the hand of the operator entersthe feed mechanism for too great a distance, the."

position of the same will be shifted for causing a quick and automatic disconnection of the power.

In the accompanyingf drawings-1 'Figure 1 is a front view of a wrlnger'of a. well known type with an embodiment of the invention applied thereto.

of 'rotation thereof by shiftingthe arm 4l from the position shown in Figure 1 tothe diametrically opposite position. Asu the rollers of the wringer were driven,4 the clothes were fed directlyI thereto which were naturally wrung in the usual' manner. Whenever desired, the operator could move the lever 4 to the dotted position shbwn in Figure 1v whereupon the clutch woul/d disconnect the rollersof the wringer from the power. A

In the present invention, means have been provided which will shift the lever or arm 4 automatically to the `dotted position shown'in Figure 1 and will also guide the f clothes to the rollers of the wringer. If

i p preferred, the device embodying the inven- "tion .could be made more orV less integral with the wringer, thoughforthe purpose of illustration, it has been made separat-e and connected thereto as an attachment. v

In forming the device, a frame consisting of arms 5 and 6 and suitable bracing and connecting rods 7 are provided.. This frame is connected'- to the wringer 2 in any suitable manner, as for instance, by having the depending hook 8 (Figure 5) of each of the arms 5 and 6 extending through suitable arms 5 and 6 vare "identical and the parts ,associated therewith arealso identical, the description of one will apply to both.

As indicated in Figures and 6, the arms 5 and 6 carry` rollers 10 and 11,'i'ollerv 10 being rotatably mounted in a fixed position while roller 11 is carried by sliding blcks 12 shiftedpby the set screw I13 whereby the tension of the belt 14 may be varied. This belt is preferably made fromrubher though it could be -made from canvas or other de# As indicated in Figure 5, the respective arms are each provided with an upstanding guidewayl receiving therespective blocks 16 which carry the journal ,brackets 9 secured to the wringer. As the f rod 17 ofthe roller 18. Thisroller co-acts with the roller 19 for supporting `the belt 20 which may be of rubber or other desired material. lSuitable springs 21 act on the blocks 16 to press the roller 18 against roller or to a position near the roller 10 whereby the clothes to be wrung may be fed properly to the rollers 22 and 23 of the wringer 2. The roller 19 is mounted on a suitable grinding block 4atfeach end, which blocks are shifted by the respective set screws 24 in order that the belt may be maintained under proper tension. It will be noted that the belt 14 is mounted to remain in a plane substantially at right angles to the vertical plane while the belt 20 is swung back `and forth as indicated in dotted lines in'Figure 6. The arms 25 and 26 are provided with -extension`s 27 and 28 which are pivotally mounted-von the'shaft 17, said arms carrying the respective blocks adjusted by the set screws 24. Also these arms carry brackets 29 and 30, each bracket having *al notch/31 formed therein for receiving the end 32 of the rod 33.l Theend 32 .is preferablyT square in'cross section so that it may slide in the slot or.notch 31 without rotation. A stop 34 is slidingly mounted on the end 32 and is clamped in position by a suit` able clamping screw 35 wherebythe eii'ective length of the rod 33-may be varied as desired. At the end opposite end 32, an eye 36 is provided which fits over the endof the crank 37 which crank may be formed-integral with the rock shaft 38- if desired.

\ Suitable stops 39 and 40 are provided on the shaft 38 to prevent its longitudinal movement in they bracket 41, which bracket is j bolted or otherwise secured to some part of the wringer 2. At the end of the shaft 38 opposite the crank 37, is provideda double .acting cam. 42 having cam members 43 and 44. These .cam members are designed to act at different times on the lever 45,l which lever is pivotally mounted at 46 in a fitting or block 47 secured in any desir-ed mannertov .the casing of the clutch 3, A bracket 48 is Valso secured to the block 47, said4 bracket having a projection or extension 49 to which one end of the'spring 50 is secured, the opposlte end of said spring being secured to the outer end of arm or lever 4. This spring is normally under some` tension and when the parts are' moved to the position shown in Figure 1, ris under appreciable tension whereby it will move to the do'tted position shown in` Figure 1 whenever permitted. The lever 45. is bifurcated at its lower end and 'formedwith ` legs 51 and 52 positioned to normally fit on top of thelever or arm 4 `when vthe wringer is in operation.

When the parts are in the position shown 1n Flgures 1, 2 and 3 and the operators hand accidentally or otherwise is moved between thetwo belts 14 and 20, the arms 25 and.

26 will be raised, though usually not as high p as that shown in Figure 4. The raising, however, of these members is suiiicient to cause a longitudinal movement of the rod l33 whereby the crank 37 is moved'and shaft 38 rocked until the cam member 43, as shown in Figure 4, has moved the lever until the leg 51 thereof slips off of the lever or arm 4. As soon as this occurs, spring 50 will move the clutch 3 to an inoperative or open position. It is, `of course, evident that the rod 33 may be moved independently at any time for causing the le 51 to move off of the lever 4. By adjusting the stop 34,'

the upper belt` may be swung to a greater or less extent in order to take articles of clothing of different thicknesses. However,

the parts are always set to cause an automatic opening of the clutch in case the hand of the operator passes in one-half or two` thirds of the way between the belts 14 and 20. The operators hand may readily pass in until it almost touches the belts near the linner rollers 10 and 18 without injury, as merely the weight of the rollers, belts and associated parts will be thereon.

It will be noted particularly from Figures 21 and 6 that the lower belt 14 projects beyond the' upper belt and suitable guide pins 53 are provided whereby the clothes to be wrung are guided properly beneath the belt 20. As the lower belt is driven, the upper belt automatically moves therewith and transports. the clothes to the squeezing rollers 22 and 23. In order that the lower belt 14 shall be driven, the shaft 54 is squared at each end so as to project through the squared aperture 55 of the sprocket wheel '56, said sprocket wheel accommodating a chain 5.7, which chainalso passes over a sprocket wheel 58 having a squared aperture 59 fitting over the squared end 60 of one of the shafts .ofthe rollers 22 Jand 23. The chain 57 and the sprocket wheels-56 and 58 are located in a housing 61, which may be connected together in any suitable manner, 'said housing having suitable aperjtures forl receiving the bosses or hubs 62 whereby a driving unit is provided which may be slipped onto the end 60 and the end of shaft 54. If it,should be desired to place the device on the opposite side of the wringer 2 as shown in dotted lines in Fig- Leanser t swingable feed member with said power dis.
