Description

Patented Sept. l2, 1939 UNITED ASTATES PATENT OFFICE A 2 Claims.

This invention relates to clothes wrlngers and has for its purpose to provide means for preventn lng damage to operators' hands and to articles of clothing passed therethrough.

It is an object of this invention to provide in such a wringer a multiple roll construction adapted to prevent the winding of the work on the squeeze rolls.

It is a further object of this invention to provide a hand guard in order to prevent the ac-l cidental engagement of the lingers of an operator with the squeeze rolls of the wringer: s

It is a further object of this invention to provide stripper means for preventing articles of clothing winding on the squeeze rolls of the wringer.

It is a further object of this vide a self-feed for a wringer.

It is a further object of this invention to provide a drain board having` a splash board adjustably secured thereto. whereby to prevent drainage to the delivery side of the wringer and contact with the wrung or dried work.

It is a further object of this invention to pro` videv such a drain board which is rigidly attached to the wringer frame and may serve to operate in the above manner to drain selectively to either side of the drain board to provide for reversible operation of the wringer without the use of an adjustably mounted drain board.

These and other advantages will appear from the following description taken in connection with the drawings.

In the drawings:

Figure 1 is a front elevational view of the invention to prowringer, with the frame latch in open position;

yFigure 2. isV an end elevational view of the l wringer, as seen from the left end of Figure l,

with the roller drive cover removed to show all the roll drive means;

Figure 3 is an elevational view in section of the wringer, taken on the line 3--3 of Figure 1;

Figure 4 is a plan view vof the drain board and attached splash board; and

-pression 4 adapted to engage a complementary projection of oneof the side standards 2, while a latch member 5 is pivotally mounted at the (ci. ca -264) opposite end of the top member and is adapted to be selectively engaged with or disengaged from a projection 6 on the opposite side standard. The side standards 2 are' each shaped substantially like an inverted cross having a horizontal 5 portion 'i extending in both directions adjacent the base .of the frame; The above described members are preferably of angle form and the members 2 each have inwardly directed substantially U-shaped anges which extend at either lo side of the squeeze rolls and around and adjacent the lower portion of the lower squeeze roll. The horizontal portion i serves to support bearing members 9, invwhlch are journaled the 1ends of the lower rolls of the wringer. These l5 bearing members, as shown, are of wood, but it is understood that any other suitable material may be usedand that the construction of these bearings may be varied within rather wide limits. The lower rolls are three in number and comprise 20 a centrally located lower squeeze roll, generally designated III, and guide and stripper rolls II disposed at either side thereof and having light contact therewith. The rolls I0 and I I comprise pntles rigidly secured to non'resilient bodies, `25

which bodies have resilient clothing or covers of rubber or equivalent resilient material.

The pintle of the roll I0 extends beyond one end of the roll I0 a substantial distance and terminates in the shaft .portion I2 having a key- 39 way I3 to provide means for attaching to the shaft portion I2 suitable powenmeans, such as a drive pulley, gear or hand crank. Suitable bearing means I4 is slidably supported by the upper vertical portions of the side standards 2 and '35 the upper`squeeze roll I5, which is of construction similar to rolls I0 and II, is journaled at each end to be freely rotatable therein. The bearing members I l are urged downwardly by a leaf spring I5a which has each end resting upon 40 one of the bearing members I4 and has a depres sion I6 in a central portion, in which is adapted to rest the lower end of an adjusting screw I6. By this means, the pressure of contact between the upper squeeze roll I5 and the lower squeeze 45 roll I0 may beadjusted as desired.

Suitable attaching means, such as bolts I1- and wi-ig nuts I8, are provided for attachment of the lower frame member I. The upper squeeze roll I5 is freelyrotatable and resiliently urged 50 downwardly against the lower squeeze roll I0, as pointed out above. The guide and stripper rolls II and lower squeeze roll IIl are all driven at the same speed and in the `same direction. The means for accomplishing the joint drive of 65 these rolls comprises the gear I9, non-rotatably secured to the pintle of the roll I0, adjacent one side standard, the gears20 attached in like manner to the pintles of the rolls II and the idler gears 2I, which drivingly connectI the gear I9 with each of the gears 20, and which idler gears are mounted for free rotation on pintles 22, which are secured to the plate 23.l The plate 23 is rigidly secured to one of the side standards and is adapted to have a housing or gear casing 24 suitably attached thereto by means of screws or studs 25. The bolts I1 and nuts I8 also provide means for attaching the drain board 26 to the upper surface of the frame member I, as

is shown particularly in Figure 3.. The drain board is substantially rectangular, but has the side edges thereof arcuate, as shown particularly in Figure 4. The upper surface of the drain board inclines downwardly from the center at a slight angle, as may be clearly seen inFigures 3 and 5. The heads of the bolts I1 are adapted to be attached to the drain board 26 through the circular portion of the keyhole slotl 21. The arcuate side flanges of the drain board are designated, 28 and have pivotally secured thereto by means of rivets 29 or other suitable pintle means, side flanges 3l of splash board 30. The upper surface of the splash board 30 is arcuate and concave, as is shown particularly in Figures 3 and 5.

Suitably attached at each side of the vertical portion of each side standard 2 is a lug 32, which has a hole therein, which is adapted to receive the upper hook portion 34 of a stripper plate supporting arm 33. The arms 33 are thus removably and pivotally attached to the wringer frame. A stripper support member 35 of angle form is secured at either end to one cf the paired stripper plate supporting arms 33 at each side of the wringer frame. Rigidly secured to the stripper support member by means of plate 31 and a plurality of screws 38 is a resilient stripper plate 36 f means 39 comprises a pair of screws which ro.

tatably support the ends of the roller 40, but it is to be understood that a rod extending between the arms 33 and secured at each end to one of said arms, may be used. The guard rollers 40,- as illustrated, are metallic, but it is to be understood that the showing thereof is merely illustrative and that the construction thereof may be varied within rather wide limits.

Operation With reference particularly to Figure 3 of the drawings, it will be seen that, upon application of power to rotate the roll II) in a clockwise direction, the rolls II will also be rotated at the same speed and in the same direction, while the upper squeeze roll I5 will be rotated in a counterclockwise direction by contact with roll IU. The operator applies pressure to the left side of the splash board 30 and tilts it until the lefthand edge thereof is in contact with the top surface of the drain board 2B. Clothing is then inserted between the lefthand guard roller 40 and the lefthand roll II which is, in this case, the feed roll. Contact of the operators hand with the guard roller 40 will prevent the hand from being caught between rolls I and I5. This is facilitated by the rotatable mounting of the roller 40. The contact of the operators hand with the roller 40 will swing stripper plate supporting arms 33 toward the roll I and the stripper plate 36 'will be brought into contact with the roll I5. 'The contact of the stripper plate 36 with the roll I5 will prevent clothing from being wound on the roll I5 during operation of the wringer.

Theclothing is carried by the feed roll II into contact with the lower squeeze roll I0, which is driven, and thence between the lower squeeze roll I0 and the upper squeeze roll I5. When the clothing travels to the right of the squeeze rolls,

-there will be a tendency to travel around the periphery of the lower squeeze roll I0, but this is prevented' by the driven rotation of the righthand roll II which, in this case, is the stripper roll and tends to strip the work from the lower squeeze roll I0 and prevent it from being wrapped around the lower squeeze roll and thus preventing injury thereto.

When' the splash plate 30 is tilted in the above-described position, its righthand edge is adjacent the lower peripheral portion of the stripper roll II, and it is thus seen that liquid removed from the work is transferred by the splash plate 30 to the lefthand inclined surface of the drain board 26 and prevented from reaching the righthand portion of the drain board- 26. It is, of course, to be understood that I comprehend the use of reversible drive means for driving the shaft portion I2 vwhereby to rotate the lower squeeze roll I0 in either direction. When the direction of rotation is opposite that described above, the rolls I0 and II will rotate in a counterclockwise direction and the righthand roll I I becomes the feed roll and the lefthand roll II becomes the stripper roll, and the upper squeeze roll I5 rotates in a clockwise direction and, instead ofthe splash board or plate 30 being tilted to the left, it will be tilted to its rightmost position and the righthand guard roller 40 and the righthand stripper plate 35 will operate in the same manner as the lefthand guard roller and lefthand stripper plate 36, described abo-ve. This is extremely convenient because the operator in reversing the operation of the wringer is not required to move anything but the splash board 30 which maybe easily swung downwardly by a sim-ple push, and it will be seen from Figure 4 that, when the lower rolls are rotating in a clockwise direction, the downward push is opposed by the guide roll I I when the operators hand comes in contact therewith, whereby there is no possibility whatsoever that the operators hand may be injured in performing this simple pushing operation. This structure thus makes the reversal stantaneous with the reversal of the power and A greatly facilitates s-uch operation of the wringer,

while providing the utmost safety of operation.

It is thus seen that my invention consists of four features, namely, stripper plates 36, guard rollers 40, driven feed roll, driven stripper roll and rigidly mounted drain board 26 having the splash board 30 adjustably mounted thereon, and it is, of course, to be understood that the omission of one will not affect the operation of the others. For instance, the guard roller 4I) might be omitted, the stripper plate 36 might be omitted and one of the driven rolls II might be omitted with corresponding loss of function, where it was not desiredto operate the wringer reversibly, likewise the rigid drain board and adjustable splash board construction might beapplied to `wringe'rs of substantially different construction and mode of operation from that described.

The above-described construction of the savants wringer frame is merely illustrative and it is to be understood that my invention may be carried out with frames oi widely varying constructions and that I do not intend to limit myself in any Way by the above description-o one frame -construction by which my invention may be carried out.

It will be further understood that the abovedescribed structure is merely illustrative of one manner in which my invention may be carried out and that I desire to compreheno' within my invention such modications as come within the scope of the claims and the invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is: Y

1. In a wringer with a frame having mounted therein a lower driven squeeze roll and a freely rotatable upper squeeze roll resiliently urged thereagainst, a. pair of arms swingably mounted at one side of said frame and having a resilient stripper plate secured thereto and adapted to be swung into Contact with said upper squeeze roll to remove clothing therefrom, said arms having hand guard means attached to 4their lower ends adjacent said stripper plate.

2. In awringer with a frame having mounted therein a driven squeeze roll and a freely rotatable squeeze roll resiliently urged thereagainst,

a feed and guide roll mounted adjacent said driven squeeze roll and drlvingly conneoted thereto to rotate in the same direction, a freely rotatable guard roller mounted on said frame for limited swinging movement toward said squeeze rolls to a point substantially centrally above said guide rol? whereby to cooperate with said guide roll to prevent entry of the hand of an operator between said squeeze rolls, said `guide roll rotating in suoli direction that portions thereof ad jacent said guard roller travel away from the operator.
