Aug. w L. KAUFF-MANv 2 WRINGER Original Filed Dec. 21; 1934 a INVENTORZ A TTORNEYS.

Patented Aug. 24, 1937 UNITED STATES WRINGER Walter L. Kauffman, II, Erie, Pa., assignor to Lovell Manufacturing Company, Erie, Pa., a corporation of Pennsylvania Application December 21, 1933, Serial No. 703,353 Renewed July 30, 1936 5 Claims.

Power clothes wringers present more or less danger to the operator in that in feeding clothes to the wringer the operator sometimes gets the fingers too close to the rolls and is caught in 5 the wringer. This results in painful injuries to the person caught. The present invention is designed to aid in preventing such accidents, and briefly consists in providing a raised portion on the clothes guide leading to the bite of the rolls of the wringer at a point adjacent to the wringer, this raised portion being such as to warn an operator moving clothes along the guide to the bite of the rolls of the dangerous proximity of the rolls. Features and details of the invention 5 will appear from the specification and claims.

A preferred embodiment of theinvention is illustrated in the accompanying drawing as follows:

Fig. 1 shows a front elevation of a wringer.

Fig. 2 a perspective View of the clothes guide detached.

Fig. 3 a section on the line 3-3 in Fig. 1.

The frame of the wringer is provided with a trough-shaped base I, side stiles 2 and a top 5 bar 3.

Wringer rolls

4 and 5 are mounted in the frame in the usual manner.

A clothes guide 6 is formed with end walls 1 and these end walls are secured to the front and rear faces of the stiles by means of bolts, or pins 8. The guide is located in feeding relation to the bite of the rolls.

Along the inner edge of the clothes guide I provide a raised portion 9 which forms a slight obstruction to the clothes, but does not prevent the ready feeding of the clothes to the bite of the wringer. This raised portion, however, forms in a measure a stop, or warning to the operator of the proximity of the rolls and thus reduces the probability of accident by reason of the operator moving the fingers into the rolls. In the normal feeding of clothes through the wringer, the hand or hands of the operator have the fingers-at least the ends of the fingers below the middle joint-under the clothes and as the fingers move upwardly along the guide carrying the clothes in front of them, the advance side of the lower portion of the four fingers engage the stop or abutment 9. This abutment is preferably of a height not only to form a warning of the proximity of the bite, but also to form a definite obstruction to the forward movement of the fingers in the normal feeding of the clothes past the abutment. To this end, preferably, the abutment is of a height engaging the major portion of the thickness of the advancing fingers below the middle joint. Furthermore, the face of the abutment prevents the passage of clothes through the abutment so that in the feeding of the clothes the clothes must be passed over the abutment. This simplifies the manufacture and also makes the feeding of the clothes notwithstanding the abutment not only safe but convenient and effective. It will be noted also that this upward slant of the raised portion 9 tends, should an abnormal feeding operation be attempted, to deflect the hand of an operator upwardly above the actual bite of the rolls and thus gives an added protection.

The clothes guide preferably has a downwardly extending flange H] which assists in guiding the expelled water into the trough-shaped base of the wringer.

What I claim as new is:

1. In a wringer, the combination of a frame; and rolls one above the other, mounted in the frame; of a clothes guide leading to the bite of the rolls, said guide having a raised portion extending upwardly to substantially the horizontal level of the bite of the rolls with a comparatively sharp crest, adjacent to the rolls, having an outward abrupt slope forming a warning abutment adapted to warn the operator feeding clothes to the rolls, of the proximity of the rolls.

2. In a wringer, the combination of a frame; and rolls one above the other, mounted in the frame; of a clothes guide leading to the bite of the rolls, said guide having a raised portion extending upwardly to substantially the horizontal level of the bite of the rolls with a comparatively sharp crest, adjacent to the rolls, having an outward abrupt slope forming a warning abutment adapted to warn the operator feeding clothes to the rolls, of the proximity of the rolls, and an inner slope extending to a point below the plane of the guide.

3. In a wringer, the combination with a frame, and rolls mounted in the frame; of a clothes guide below the path of the clothes leading to the rolls, and located in feeding relation to the bite of the rolls, said guide having a finger engaging warning abutment on its upper surface along the roll side of the .guide, the face of the abutment having a guiding surface sufficiently unbroken to lead clothes being fed to the rolls upward and over the top edge thereof.

4. In a wringer. the combination with a frame, and rolls mounted in the frame; of a clothes guide below the path of the clothes leading to the rolls, and located in feeding relation to the bite of the rolls, said guide having a finger engaging warning abutment on its upper surface along the roll side of the guide of a, height obstructing the passage of an operators hand in a normal feeding movement into the roll bite, the face of the abutment having a guiding surface sufiiciently unbroken to lead clothes being fed to the rolls upward and over the top edge thereof.

5. In a wringer, the combination with a frame, and rolls mounted in the frame; of a clothes guide below the path of the clothes leading to the rolls, and located in feeding relation to the bite of the rolls, said guide having a finger engaging warning abutment on its upper surface along the roll side of the guide of a height to abut the major portion of the thickness of an operators forefinger below the middle joint, advancing against the abutment in the feeding operation, the face of the abutment having a guiding surface suiiiciently unbroken to lead clothes being fed to the rolls upward and over the top edge thereof.
