1 Claim. (Cl. 68-263) This invention is a clothes wringer with a nonflying pressure reset lever norrnally lying over the top bar of the wringer frame. In this location, the lever is out of the way except when needed to reset the -Wringer pressure. The location also permits the lever to be of such length that little effort is required to reset the pressure.
In the drawing, Pig. l is a front elevation of a clothes wringer; Fig. 2 is a similar view with parts removed; Fig. 3 shows the manner of resetting the pressure; Fig. 4 is a section on line 4-4 of Fig. 2; and Fig. 5 is an end view of the outer end of the wringer With its shroud removed.
The Wringer rolls 1 and 2 are mounted in the usual manner in uprights 3 and 4 of the lower frame of the wringer. The upright 3 is attached by a bracket 5 to a wringer head 6 contaning the usual reversing gearing controlled by gear shift lever 7. The wringer head 6 has at its lower end a tubular section 8 by which the wringer may be supported on the wringer post of a domestic washing machine. The wringer head is enclosed by a shroud 9. The end of the wringer opposite the head is enclosed by a shroud 10. Clothes are guided to the rolls by water boards 11 fixed to the uprights 3, 4 on opposite sides of the wriuger.
The roll pressure is applied by a channel-shaped member 12 pivoted at one end on a bracket 13 attached to the Vertical frame member 3 and at the other end to a toggle link 14 associated with a toggle link 15 pivoted at 16 on a lbracket 17 fixed to the Vertical frame member 4. In the roll pressure applying position shown in Fig. 2, the common pivot 18 of the toggle links is outside (to the right of) a center line connecting the pivots 16 and 19 so that the toggle is in an unstable position. The toggle is held in this position by a latch 20 ha'viug a hook 21 cooperating with the lower end of the toggle link 15. To release the toggle, the latch 20 is moved downward, for example, by one of the cranks 22, 23, respectively associated with release bar 24, 25 as shown in greater de` tail in Patent 2,659,227. When the toggle links 14, 15 are in the pressure applying positon, a projetcion 26 at the center of the channel member 12 engages a leaf spring 27 which applies the pressure to the rolls in the usual manner. In the pressure applying position, tabs 28, 29 on opposite sides of the member 12 vfit into the upper ends of Vertical frame members 3, 4., In this position, the upper end of Vertical frame 4 fits in a notch 29a which prevents spreading of the upper ends of the frame members, and assists in holding the pivots 16, 19 in the desired position. If the upper ends of the frame ' members 3, 4 should spread apart under heavy load, the common pivot 18 of the toggle links would move toward the stable side of the center line connecting the pivots 16 and 19 with the result that the toggle Would not release the pressure when the hook 21 of the latch member 20 was moved downward. This is undesirable because the need for releasing the pressure is greatest when the pressure is heaviest.
f United States Patent O When the toggle is released, the roll pressure stored in the leaf spring 27 exerts a torque on the channel member 12 tending to pivot it in a counter'clockwise direction about its pivot on bracket 13. The toggle link 15 likewise pivots in a counter-clockwise direction about its pivot 16 moving the assoicated end of the channel member 12 upward a distance suflicient to completely release the pressure between the rolls 1 and 2. Since the toggle links 14, 15 are enclosed in the shroud 10, the user is protected from injury by the toggle links. As the toggle links swing outward to release the wringng pressure, the channel member 12 moves upward but at a much slower rate due to its greater length. The upward movement of the member 12 is directly above the center of the wringer which is a location in which even a violent movement would be unlkely to injure the operator.
The wringing pressure is reset 'by a channel-shaped lever 30 which in the wringing position overlies the channel member 12 with its front and back side Walls 30a and 3017 telescoped over and enclosing the channel member 12. The lever 3G has a handle 31 above the shroud 9 of the wringer head and at the opposite end has fixed on its underside a bracket '32 pivoted on the pivot 19 for the toggle link 14. In the wringing position there is a subtantial clearance between the bracket 32 and a flange 33 on the toggle link 14. Because of this clearance, any upward swinging of the toggle links during the release of pressure does not affect the lever 39. The lever 28 merely lies quietly on the channel member 12.
When the roll pressure is to be reapplied, the operator grasps the handle 31 and lifts the lever 30 upward, pivoting it about the pivot 19. As shown in Fig. 3, this brings the bracket 32 against the flange 33 and exerts a torque on the toggle link 14 tending to turn it in a clockwise direction about the pivot 19 and to move the toggle toward the pressure applying position illustrated in Fig. 2. Since the lever 30 is very long compared to the length of the toggle links, little effort is required to return the toggle links to the pressure position even under very heavy pressure.
The top frame 12 can be narrow since it merely sustains the roll pressure and does not enclose the upper roll.
What is clairned as new is:
In a Wringer of the type having upper and lower rolls carried in a bottom frame, said bottom frame having vertical side members with pockets at their upper ends, a roll pressure bar extending over the upper roll, said roll pressure bar having tabs projecting from the bottom thereof which enter the pockets at the upper ends of the Vertical side members of the lower frame, said roll pressure bar having a projection at one end on its lower face pivotally attac'hed to a bracket extending outwardly from the top of the bottorrrframe, the other end of the roll pressure bar likewise having a projection extending downwardly from the end of the pressure bar and being pivotally connected to one end of a first link of a toggle, the other end of the first link being pivotally connetced to one end of a second link, the 'other end of said second link being pivotally connected to a bracket extending outwardly from the other side of the lower frame, and a reset lever of channel Shape completely overlying the upper 'roll and the projections extending 'on each side of the roll pressure bar, said reset lever having a bracket at one end on its under side pivotally connetced to the roll pressure bar and to said one end of said first link of the toggle mechanism about a common pivot, the common pivot connection for the reset lever and the roll pressure bar and the first link being outwardly ofiset from a plane passing through the Patented Apr. 11, 1961 pivotal connection between the first and second links and the pivotal connection of the `other end of the second link to the bracket on the lower [frame member, whereby in a closed position the toggle links are unstable, and a pressure release mechanism'carried onthe outer side of theV -upright of the lower frame engaging the end of the second lever adjacent the pivotal connection to the first lever to release the `unstable toggle links.
