Patented Mar. 28, 1933 PATENT OFFICE JULIAN L. PERKINS, OF WEST SPRINGFIELD, MASSACHUSETTS WBINGER Application filed April 6,

This invention. relates, to improvements in wringer apparatus and is directed more particularly to wringers of the safety type.

The principal objects of this invention are directed to the provision of a safety Wringer apparatus which incorporates novel features of construction and arrangement of parts, whereby the operator may easily and readily disconnect the operating parts to safeguard against injury and damage.

Numerous novel features and advantages of the invention will be hereinafter more fully referred to in connection with the following description of the preferred form of the invention, which for purposes of disclosure is shown in the accompanying drawings, Where- 1n:

Fig. 1 is a side elevational view of a wringer apparatus embodying the novel features of the invention.

Fig. 2 is a longitudinal sectional view through the wringer apparatus shown in Fig. 1.

Fig. 3 is a plan view of the same.

Fig. 4 is a transverse sectional view on the line 44 of Fig. 2.

Fig. 5 is an end elevational View at the left-hand end of the wringer apparatus showing the parts in a neutral position, and

Fig. 6 is a similar view showing the parts in an operative position.

Referring now to the drawings, the invention will be more fully described, but it will be obvious that changes may be made to adapt the same to various conditions.

The wringer apparatus in its broad aspect is adapted for use in connection with washing machines and similar apparatus. In the form of the invention to be described it is associated with a head or driving unit indicated generally by H. In the drawings the head H includes a housing 2 having a tubular support member 4 extending therefrom which may be attached to and supported by an apparatus such as a washing machine or the like. A driveshaft 6 is journalled in a suitable bearing 8 and carries a driving pinion 10 on its upper end. A barrel 12 is 0 rotatable and reciprocable in the housing and 1931. Serial No. 528,094.

be rotated in one direction or the other. As 60 the parts are shown in Fig. 2, the driving a shaft 14 is shown in a neutral position wherein neither of the driven gears are in mesh with the driving pinion.

The barrel 12 has an upwardly extending pin 22 which extends into a slot 24 in the upper side of the housing 2. This slot 24 is arranged so that when the bushing is rotated in reference to the housing in one direction or the other it will be simultaneously moved longitudinally thereof and moves the shaft 14 therewith so as to engage either one of the gears 16 or 18 with the driving pinion. The parts are shown in Fig. 2, as being in an inoperative neutral position.

A guide 30 extends upwardly from the outer end of barrel 12 and is preferably tubular to receive in sliding relation a carrier 32 which is also tubular and slidably receives a box 34. A drive roll 36 is carried by the shaft 14 and at the outer end of the shaft 14 there is provided a guide 40 which has a bearing portion 42 on the shaft. As will be seen the shaft 14 may rotate relative to the barrel 12 and the bearing 42 so as to rotate the drive roll 36.

A carrier 44 similar to the carrier 32 is slidable relative to the guide 40 and has a box 46 slidable therein corresponding to the box 34 of carrier 32. A shaft 50 has its 0 posite ends in a slot 52 in the inner walls 0 the boxes-34 and 46.

Slots 31 and 33 are provided in the inner sides of the guides and carriers to permit the shaft 50 to move towards and away from the drive shaft and to permit relative movements of the boxes, carriers, guides and shaft 50.

A driven roll 51 is carried by the shaft 50 and is preferably rotatable thereon, the shaft bein held against rotation because the ends 'of s aft are non-round as indicated at 53.

Of course the shaft 50 may be arranged to rotate in the boxes.

Adjusting screws 56 are in screw-threaded engagement with the upper ends of the carriers 32 and 44 and bear on the s rin s 58 within the boxes. The lower en s o the springs abut the lower walls of the boxes such as 60. The springs function to urge the boxes downwardly relative to the carriers and when the carriers are in the lower position shown in Figs. 2, 5 and 6, the upper roll 51 is yieldingly urged into contact with the lower drive roll 36.

In the operation of the apparatus when the lower shaft 14 and rolls 36 are to be rotated in one direction or the other, the wringer is tilted in one direction or the other from the neutral inoperative position shown in Figs. 1, 2, 3 and 5. For instance, it may be tilted to the osition shown in Fig. 6. As it is tilted the barrel 12 is oscillated in the housing so as to carry the pin 22 along the slot 24 and simultaneously move the barrel, shaft 14 andwringer longitudinally to engage one of the driving gears with the pinion. In a tilted position and with one of'the driven gears in mesh with the driving pinion the lower roll shaft 14 and lower driving roll 36 are driven from the shaft 6 whereby the upper roll may be driven by the lower one when the carriers are in a lower position.

The carriers are releasably held in a lower operative position so as to yieldingly urge the boxes downwardly and yieldingly hold the upper roll against the lower one and the mechanism for this function will now be described.

Levers are rotatable on the barrel 12 and on the bearing 42 at op osite ends of the roll 36. These have slots 72 diverging from a lower slot 73 to provide a'cam portion 74. Pins 76 carried by the lower ends of the carriers 32 and 44 work in the slots of the levers 70 and as the levers are swung relative to the carriers and from the full line ositions shown in Figs. 5 and 6, to the dotash line position, the ins are allowed to travel upwardly of a s 0t 72.

As the pins may travel upwardly of the slots 72 of the levers 70, the carriers and boxes therein are free to move upwardly relative to the guides. In this Way should an operator have a hand caught between the rolls, the upper roll may be moved upwardly by the hand since the carriers are not held against upward movement.

At all times the boxes and upper roll- 51 are spring-pressed downwardly relative to thecarriers. -The carriers are free to move upwardly except when releasably held in up erative position by the levers 7 O. The springs do not act on the upper roll when the carriers are released so as to press against the lower roll. The springs function only when the carriers are held in a lower operative position as shown clearly in Figs. 5 and 6.

Rods or bars 80 are connected between arms 82 of the levers 70 and are arranged to lie at opposite sides of the rolls. The bars are readily and easily accessible to the operator regardless of which side of the apparatus the operator is ositioned for the operation of the wringer. guite involuntarily and unconsciously the operator, in an emergency, may grasp one of the rods or contact some part of the body therewith to cause either an upward or downward movement thereof to bring the safety feature into operation.

A bar or bars 90 may connect the upper ends of the guides 30 and 40 whereby the wringer may be tilted between neutral and operative positions.

The wringer may be moved between a substantially vertical neutral position and angularly disposed tilting positions which will depend more or less upon the operator who may stand at either side of the wringer. In any event at least one of the rods 80 will be disposed between the operator and the wringer so as to be in the path of the arms of the operator or at least will be readily accessible for manual operation.

A detent 100 in the form of a ball is spring pressed upwardly by means of a spring 102 for engagement with an opening 104 in the lower side of the barrel 12. The parts are so arranged that the ball and opening will be engaged when the wringer is in a neutral inoperative position so as to yieldingly hold the wripger in such a position.

Not only may the operator actuate the levers 7 O for the safety function and thereby avoid injury, but in case the wringer is in a tilted operative position the operator may swing the structure from such tilted position to the neutral position, wherein the driven gears are moved from engagement with the driving pinion. In this position the lower roll 36 will not be driven and the danger of the rolls drawing the operators clothing or hand therethrough is eliminated.

'Itwill be noted that the wringer structure is supported entirely by the driving shaft and that it is movable between operative and inoperative positions. The novel construction eliminates the necessity for a wringer frame usually employed. Therefore the wringer of this invention is simple in form so as to be economical to manufacture and efficient in its operation. By reason of the novel construction an operator may quite unconsciously bring the safety feature into play to safeguard against injury and damage.

Various changes may be made in the form of the apparatus without departing from the spirit and scope thereof and therefore it IS preferred to be limited if at all by the apa spaced relation, connections between said.
