WASHING-MACHINE WRINGER.

Application filed June 13, 1924, Serial No. 719,835, and in Canada November 14., 1923.

Myv invention relates to wringers of that class adapted to be used in combination with power driven washing machines.

The wringer is specially adapted to be operated by the same motive power as that used to operate the washer.

The object of the invention is to provide means to protect the operator ofthe ma chine, in the event of the hands, hair or parts of the clothing becoming caught or drawn into the wringer while in motion.

The machine is constructed that in the event of an operators hand or clothing be- 7 coming in any way caught in between the being rollers of the wringer, pressure may be im parted against the upper part of the frame of the machine, in either direction, by which it will throw over and release the tension on the rollers, other than the weight of the upper roller bearing downwardly.

The upper portion of the frame is pivotally I connected with the lower portion, the spring tension by which the rollers are forced together, being carried by the upper portion, so that by throwing over the upper portion of the frame, in either direction, the tension will be instantly removed from the rollers. Throwing over the upper portion of the frame, also provides for the release and removal of the rollers.

The essential object of the invention is to provide means by which theoperator may instantly, throw the rollers out of. contact and out of gear,'in the event of the operator getting the hand or clothing caught in between therollers while in motion.

In the drawings:

Figure 1 is a side elevational view of the wringer;

Figure 2 is a side elevational view of the wringer showing the upper portion of the frame adjusted over to one side; v

Figure 3 is an end elevational view of th wringer;

Figure 4 is a detail elevational view of the wrilnger showing the upper roller removed, an I Figure 5 is a detail perspective view of one end of the top roller.

Like letters of reference refer to like parts throughout the drawings and specifications.

The frame of the wringer consists of an upper and lower member, the upper member held in pivotal relation to the ends of the lower member. The lower member carries the driving mechanism, the starting and stopping means. These parts do not embody any novel feature of the combination, and have therefore been omitted from the drawings. 7

.In construction, the lower member consists of a base a formed from angle bars, with which the device may be suitably connected 1n' p1votal relation with the washing machine, 1n a manner by which it may be swung around into various positions convenient for operation. A short section a of the base a extends beyond one end of the lower member, and is intended to carry the driving, starting and stopping mechanism. These features have not been shown.

Extending in vertical relation from the base a are end frames bb in which are formed vertical guideways c-'c in which are set yournal-boxes cZaZ and dd, in which are ournaled the ends of the spindles e and e of the rollers f and g respectively.

The upper member of the frame consists of abridge 71. formed with depending end pieces z'c', which pivotally connect with the end frames 6-4) of the lower member.

Formed in the inner walls of the end pleces z' i are guide-ways j-j in which are carried tension blocks 7c7c in which the outer ends of the tension spring Z ride. The

tension spring 1 is carried by the blocks kk and the bridge h. The tension of the spring is regulated b an adjusting screw m, which,

passes throug the centre of the bridge h. The screw is operated by an ordinary handle n formed therewith, the tension of the spring Z and the blocks Iii-16 being increased or reduced by turning the handle in either directign.

0 an 17, respectively, desi ate s ur ears keyed on the ends of the s p indles ei' of the rollers f and g. By the meshing of the gears the rollers turn in unison.

One end. of the spindle e of the roller f t des1gnates a spring bolt fitted through vthe end frame b. The bolt is adapted to engage with stops it formed in the ends of the drip-pan to maintain it in any adjusted positio The top face of the journal-boxes dd' of the roller 9 are slightly curvedz, to facilitate in disengaging from contact with the tension blocks 10-70, when the upper mem- :-ber is being forced over in either direction tension wing projecting inwardly from the end piece i, at the end at which the spur gears 0 and p are located, the object of the wing being to overhang the gear ;0 of the roller 9,. to prevent objects when passing between the rollers from coming in contact with and being drawn into the gears, and also to prevent accidental contact of the ears by the operator when the wringer is ing used.

Various modifications may be made in the form and arrangement of the several parts, without in any way deviating from the nature of my invention.

What I claim as new and desire to secure by Letters Patent is 1. A wringer, comprising a frame consisting of a lower member and an upper member, said upper member being held in pivotal relation with said lower member, rollers suitably journaled in said lower member, a flat spring adjustably fitted in said upper member, the ends of said spring imparting pressure on the ends of said rollers, said upper member bein adapted to be swung about its pivot to either side of a plane passing through the wringer rolls to disengage and release the downward pressure on the ends of the said rollers, as and for the purpose specified.

2. A wringer, comprising a frame consisting of a lower and an upper member, said upper member and lower member being held together in pivotal relation, vertical guideways formed in the sides of said lower member, journal boxes set in said guide-ways,

roller spindles journaled in said journal upper member, t e ends of said s ring pressing on ournal boxes set in said ower member, rollers suitably journaled in said journal boxes, said upper member being adapted to be swung about its pivot to either side of a plane passing through the wringer rolls to disengage and release the downward pressure on said journal boxes, as-and for the purpose specified.

4. A wringer, comprising a frame consisting of a lower member and an upper member, vertical guide-ways formed 1n ends of said members, journal boxes fitted in the guide-ways in the lower member, rollers journaled in said journal boxes, sald up er member being pivoted to said lower mem cr on an axis parallel to the axis of the rolls,

blocks fitted in the guide-ways in the upper member, a flat spring adjustably fitted in said upper member, the ends of said spring resting on said blocks, said blocks, when the upper member is in the plane of the rolls, pressing on the journal boxes and thereby pressing said rolls together, and said u per member, when swung on its pivot toelther side of the plane passing through the rolls,

causing the journal boxes to be released from pressure by said blocks, thereby releasing the pressure on the rolls.
