Patented Oct. 18, 1938 l UNITED STATES PATENT vOFFICE `WltlNGrElt y Julian L. Perkins, West Springfield, Mass.

Application. October 6, 1533, Serial No. 692,481 Renewed March 11, 1936 21s claims. (ci. sa-2573) sion of a wringer .which has associated .there-Y with means adapted for movements between operative and inoperative positions and motor control means associated with the said movable means s0 that current to themotor may be cut oil? while the movable means is in operative position whereby ,anA operator may instantly cause the motor to be stopped and thus obviate injury.

A further object of the invention is the provision of a wringer having co-actingrolls, one-of whichy has a member associated therewith for releasably locking the roll in an operative position and motor control means associated with the member which is conveniently located so that an operator may instantly stopthe driving motor and simultaneously release the rolls from operative position.` Y Y A further object of the invention is the provision of a Wringer having a guard member and associated roll adapted to be releasably connected to a4 frame in which is a roll. 'I'he guard is adapted to swing between aneutral inoperative position and operative positions at either side thereof in which operative positions theguard is releasably locked. y

'A still further object of the invention resides in' the provision of means for rotating the rolls oi the wringer in opposite directions so that the feeding-in side of the .wringer may be at either side thereof in combination with novel means to control the locking of the guard and its associated roll to the frame in a position at the feeding-in side of the wringer at all times. In that way, the guard is in the path of the-arms of the operator of theA wringer at all times ywhen in cperatiomwhereby the operator may readily and easily engage the same to swing the guard to an inoperative and thereby release the same guard.. f

Further and various objects and advantages of the invention will be hereinafter more fully referredto in connection with ther accompanying description of the present preferred form there- L. Perkins (the applicant) et al.

of, which for purposes of disclosure is shown in the accompanying drawings wherein: Fig. 1 is a side elevational view of a washing machine apparatus having the novel'wringer apparatus of the invention associated therewith. -5 Fig. 2 is a longitudinal elevational and sectional view showing a wringer having certain features of the invention associated therewith, and

Fig` 3 is a transverse sectional view on the line 3-2 of Fig. 2 to show certain features of conl0 struction. f

' Referring now to the drawings more in detail the invention will be I'ully described. y

In Fig. 1 a washing machine is shown which has the usual tub 2 supported as by legs l. A 16 motor M is insome suitable manner associated with the washing machine and, as is ordinary practice, operates aA paddle or other agitating mechanism within the tub as well as operates the Wringer.

A column 8, associated with the machine, has a shaft therein thatis driven from the motor. A gear mechanism, usually referred to as a head and indicated at H, is carried by the column 8 and a wringer structure W is associatedwith the head. v

The head H includes a casing I2 havingv a driven shaft I4 rotatable therein. A pair of driven gears I6 are slidable, but non-rotatable, on the shaft I4 so` as vto be shiftable back and forth. In this way one or the other of the gears may be brought into meshing engagement with a driving pinion I8 on the upper end of the shaft I0. With the shaft I0 rotating in one direction it is possible byy shifting the gears lI6 to rotate the shaft I 4in one direction or the other. 'I'he head may take various forms and may be like `that shown in United States Letters Patent 1,875,487 of September 6, 1932, issued to Julian A lever 20 for shifting the gears works ina slot 22. This is movable back and forth so as to shift the gears I6 backhand forth after the manner clearly described in the beforementioned patent.

The wringer W has end frames 24 tied in spaced relation by a rod or tube 20', and the left-hand frame is secured to the casing I2. Bearing blocks 26 are located in slots 2 8 of the frames and rotatably support a shaft 30 of a lower roll 32 which in this case may be called 50 a drive roll.

The end of the shaft 30 may be connected to the shaft Il by .a coupling'or the like but as shown a key 34 is provided for operatively connecting the shafts I4 and 30 so that the latter u is driven by the former. Receivers indicated generally by Il are slidable up and down in the end frames-24; These receivers have ears l2 .1(see Fig. 3) through which pass bolts M which bolts are slidable in bosses of the end frames.

Chambers 48 are provided around the bolts below the bosses Il and springs il surround the bolts. These are under tension between the parts' II and heads 52 on the lower ends of the bolts. The springs are so arranged as to yieldingly pull the receivers downwardly so that .when thewringer rolls are in operable relation the upper roll is under tension as will appear.

The receivers on their adjacent inner faces are provided with guard-receiving slots Mextending up and down in a vertical relation and intermediate the ends of the slots there are provided recesses such as shown in Fig. 3.

A roll guard assembly similar to that in my United States Letters Patent No. 1,906,406 consists of a guard or swingable upper frame or upper swingable frame part member 80 which has spaced end portions 62. Hubs 64 are provided on the lower end of the guard portions 62 and these carry a shaft 66 of an upper roll 33. The shaft 86 and roll 33 may be integral with the shaft rotatable in the hubs or the shaft may be secured to a hub as by a set screw 65, with the roll 33 rotatable on the shaft 66.

n A projection 68 is provided'preferablyron each end o! the upper frame member and in the form of the invention shown this is a roll rotatable on a pin 10 carried by the upperframe member. The upper frame member is 'in the shape of a bail for ease in manipulation so that the frame member and roll may' be removed from the receivers or dropped thereinto asmay be desired. 'I'he slots 52 are soarranged that the hubs 64 of the upper frame member are received therein whereby the roll 3l may be lowered ontothe roll 32 therebelow with the frame member in an upright, neutral and inoperative position. In order to releasably lock the upperframe member and its roll in operative position the frame member is tilted from its central, neutral,

inoperative position to one side or the other. As shown in Fig. 3 when the upper roll rests on the lower one the hubs of the upper frame member are disposed in the lower ends of the receiver slots Il to permit swinging of the frame member which when swung will cause the projection to be carried into one recess 54 or the other of the receivers. The recesses are so arranged as toreleasably lock the upper frame member in a tilted operative positionas shown in Fig. 3. In this position and by reason of the camming action brought about by swingingA of the upper frame member the receivers are elevated slightly against the action of the springs 50 whereby the frame member is releasably locked in the receivers under the influence of the springs.

A circuit control switch 10 ls associated with the upper frame member 60 which may be ofV usual form and has a swinging operating lever member 12. Preferably the switch will be arranged so that it is in non-circuit closing position when the member 12 is in a lower position ask shown in Fig. 2.. When the member 12 is swung upwardly'the switch will be in circuitclosing position.

A cable 'N'extends from the switch I0 to a plug 18 provided with prongs 18 receivable in a receptacle 80 fixed in a member 82 associated with one of the wringer end frames. The plug 16 and receptacle l0 are so arranged that when described in detail.

:naam

the receptacle and disconnect the same. A cable y 84 extends from the receptacle to the motor'M and by disconnecting the receptacle and plug the circuit to the motor is disconnected. A manually engageable grip bar 9| has a pin 92 slidable in the upper trame member and a rod I4 also slidable in the frame member is Vprovided with an opening 96 which receives the lever 'I2 of the switch. As the grip $0 and rod Ol are moved towards and away from the upper frame member the lever of the switch 12 is swung up and down or back and forth to make or break a circuit.

A lock member |06 is pivoted at il! to the upper frame member and has `a slot IM at one end which receives a pin |01 of a rod I" iixed to the grip 90. As the member 90 is moved 'towards and away from the frame member the lock member i is moved up and. down. Slots i I0' are provided ln the receivers at the upper sides thereof and at either side oi' the central slots 52. The slots lill' are arranged to receive an end latch portion H2 oi the lock member IM.

Cap members II4 are pivoted as at Il! to the receivers and they may swing fromthe position shown in Fig. 3 where they overlie the receivers and the slot thereof to a position at one side thereof. The caps are swingable as the upper frame member is withdrawn from the receivers and when in an open position permit the frame member to be dropped into the receivers.

The operation of the apparatus `will now be As shown in Fig. 2' the upper frame member 60 and upper roll 30 are in a neutral. vertical and inoperative position with the operating member 90 in its depressed position nearest the upper frame member. In this position the lock member has its end portion H2 above the upper ends or sides of the receivers, and from this position the upper frame member may be swung in one direction4 or the other.

'It will be assumed that the plug 16 is inthe receptacle lil so as to connect the motor M to the switch 10 which is in oil' position. The gears il are positioned so that the roll l2 is operated in the desired direction.

The upper frame member is swung from the neutral, vertical and inoperative position mentioned to a tilted operative position such as shown in Fig. 3. The upper frame member is releasably locked to the receivers in this operative position by means of the hubs and projections in the slots and recesses thereof as has been described. `As the member 90 is moved upwardly away from the upper frame member and when the upperframe member 1s in this tilted operative position the lock lil'is swung so that its part H2 enters a slot H0. In this'way theV upper frame member is releasably held against swinging to a neutral,

inoperative position. As the member 90 ispulled upwardly into an operative position, the arm or u lever l2 of the switch device is moved to close the circuit including the switch and `the motor M, whereupon the motor is set in operation and the lower roll k32 is driven thereby through lthe gears:

described.

During the, wringing operation the upper roll yields to accommodate material being passed between the rolls. Should it be necessary and desirable however to instantly stop the wringer the operator has but to strike the member 90 lightly to thereby depress it and shift lever 12 of the r anales switch and out oi! thecurrent. y'I'his movement o! the member 90 swings the lock member downwardly so that its outer end H2 isremoved from the slot. f 1

Thus, simultaneously with striking the member l., the operator may swing the upper frame member'` to-its neutral, operative position and release the frame member from the receivers. It is not only possible therefor to instantly cut on the current to the motor driving the wringer but release the upper tramememberfas well. Should an` operator have a hand or other part caught beteen the rolls he is safeguardedagainstinjury by striking the grip 90 and at the same time, swinging the frame member. i

When the upper frame member is swung tol neu- "r trai position and it is desired to removethe same from the wringerit may be `done byvsimply raising the frame member and simultaneously with 'rising movement the plug 16 is 'withdrawn from the receptacle Ill to break the motor line.

'Itwill be noted that the upper frame member when in the receiversmay be swungin either or opposite directions fromv the central inoperative Within easy reach.

' away from the operator to insure'that the .up-

per'frame member is readily accessible.v This includes a control member Illl associated with the shaft which. frictionally embraces theshaft. Thisis accomplished by splitting the hub H2 of the member as at IH.

With the leading-in sideiof the rolls at' the left, as shown in Fig. 3, the shaft 30 rotates clockwise and swings the member H0 to the right against some stationary part such as the sideof the slot l2 of the receiver. In this position the upperfend H6 0f the member is in front of the recesses 54 vat the right of the receiver whereby the projection il of the upper frame member cannot seat in the receiver. recesses at the right. To lock the frame member it must be swung away from the member III` to the leading-in side of the wringer at the. left thereof. The shaft 30 slips in the member l I0 and frictionally urges it towards the side of the slot. f f When the shaft 30 is rotated counter-clockwise so as tobring the leading-in side at the right of the wringer the member III) is swung to the left side of thek receiver andthe upper frame member can only be swung to the leading-in side or tothe right. `This insures that the frame member when in operative position is at theleadingfin side and the side of the wringerat which the'operator will stand.
