WBINGER.

Application filed April 26, 1923. Serial No. 654 707.

This invention relates to wringers, and

more particularly in some of its more speolfic details to wringersfor wrlnging clot es or the like, which is especially adaptedfor employment in connection with washing machines.

It is a general object of the invention to provide an improved wringer construction of the class mentioned which is durable and satisfactory in use, having few parts and being unlikely to get out of order, and being furthermore susceptible of ready assembly or disassembly and repair, and comparatively inexpensive in production costs.

A further object of the invention is to provide an improved adjustable releasing mechanism for the rolls of wringers or the like, being adapted to support the rolls securely in desired tension and easily and instantaneously tripped by a convenient arrangement susceptible of easy resetting.

A still further object is the provision of an improved system of drainage for wringers or the like, whereby moisture such as the liquor 7 into a tub or other convenient receptacle.

wringers or the like, greatly facilitating assembly or disassembly of the wringer and which is light, rigid,.and presents a finished external appearance.

Other objects will be in part obvious in connection with the following detailed description of an illustrative but preferred embodiment of the invention, and will be in part pointed out in connection therewith,

This invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the constructions hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a more complete understanding of the nature and objects of the invention, reference is had to the following detailed description and to the accompanying drawings, 111

which Fig. 1 is an end elevation of a wringer constructed in accordance with the invention, the end plate for supporting the driving shaft being removed Fig. 2 is a broken top plan view of the same;

Fig. 3 is a vertical transverse sectional view wrung from the clothes is conducted awaying of the front and back drain boards;

Fig. 7 is a section on the line 77 of Fig. 3 showing the roll releasing mechanism in plan;

Fig. 8 is a detailed section similar to that of Fig. 3, but showing the roll releasing mechanism in a different position; and

Fig. 9 is a detail View of part of the releas-m, ing mechanism.

Referring to the drawing for a detailed description of the embodiment of the invention there illustrated,the wringer includes a frame indicated generally by 10 in which a pair of cooperating parallel rolls 11 are mounted, the lower roll being shown as connected to a driving shaft 12, separably coupled with the roll shaft, and supported in a bracket 13 bolted to the end frame of the wringer. The wringer frame is preferably of metal and made in separable front and back mating sections 14, the sections being similar and detachably secured together as by screws 15. Each of these sections has a lower substantially horizontal base section 16 with upright end sections 17 and 18 disposed at opposite ends of the frame. Both the horizontal and the end frame sections are preferably formed with opposing concavities, and when secured together form a hollow or tubular frame providing a light and rigid construction well adapted for mounting the operative parts of the wringer. The front and back halves or sections 14 being readily detachable from each other, also provide ready means of disassembly and repair undue distribution or spattering of the water i swinging drain spout 20. This spout is pref-.

erably made in separable halves detachably secured together and is connected with the conduit outlet by a tongue and groove connec tion 21 to permit swinging adjustment of the spout to discharge as desired into the washertub or other adjacent receptacle. In this connection it is noted that the wringer is especially adapted for use in connection with washing machines where the wringer is adapted to swing from one position to another, but it may be used in other relations. The cooperating edges of the wringer sections fit snugly together and may be provided with a packing to secure a liquid tight joint along the conduit 19.

Each frame section is provided with integral supporting brackets 22 and 23 for supporting drain boards 24 preferablypivoted thereto as by pivot screws 25 positioned adjacent to outer edges of. the boards so the latter may be swung outwardly. The drain boards may be of wood but are preferably of metal as shown, having smooth upper surfaces across which the clothes pass and are preferably formed with drain openings 26 for carrying away the surface moisture into the drain conduit below. For supporting the drain boards in properly downwardly inclined position with reference to the frame,

supporting lugs 27 may be provided on the brackets 23 being adapted to cooperate with lugs or flanges 28 formed on the under side of the drain boards.

Extending between the supporting brackets 22 and 23 and underlying the drain boards are (ill drain tables or plates 29 inclining upwardly from the longitudinal d ain conduit being adapted to conduct drippings to the main drain conduit and also functioning as a rigidifying member for the main wringer frame.

Thus it will be seen that the main drain con- "duit has a widely opening upwardlydirected mouth well adapted to catch drippings from the wringer rolls, from the clothes as they are approaching the rolls, or from other parts.

The supporting shafts 30 of the rolls extend through medial slots in the inner walls of the end sections of the frame to points Within said tubular end sections being supported in bearings 31 housed also in the end sections. Bearings 32 for the shafts are supported by lugs 33 preferably'integral with the frame sections and being confined from longitudinal movement by lugs or flanges 34 on one side and the inner wall of the tubularend section on the other side. The upper bearings 31 are similarly confined from. longitudinal movement by means of the inner walls of the end sections of the frame and by supporting and guiding flanges 35, but are supported against roller pressure transversely of the roll shaft by means of adjusting screws 36 and 37. The adjusting screw 37 is preferably mounted in a cap 38 surmounting one of the end sections and detachably secured thereto having its inner end in contact with a metal band or plate on the bearing block to receive tension thrust of the rolls. This adjusting screw is preferably provided with an externally knurled operating knob.

The adjusting screw 36 on the opposite end section of the frame is similarly mounted in a detachable cap 39 surmounting the end section and detachably secured thereto, but in this case the detail construction is modified to furnish a roll release. engages with a metallic plate on the bearing block 31 but instead of being threaded into the cap as in the case-of adjusting screw- 37, it

in the inner wall of the end section, as indicated in Figs. 4, 7 and 9. The abutment block 40 is normally held in operative position .to

.receive the thrust of the roll tension when in use by means of a pair of oppositely disposed dogs or detents 42 pivoted to the cap section 39 and normally biased by springs 43, also mounted in the cap section, into position to engage with the abutment block to hold the same securely in position. Each of these dogs is provided with an inwardly projecting arm 44 having curved terminal portions underlying the stem 45 of the knurled operating knob 46. The stem of the operating knob is provided with a square aperture 47 into which the square projection 48 of the adjusting screw 36 is adapted to project, the operating knob being longitudinally slidable upon the square projection. As shownin Fig.3, normally the locking dogs 42 are held in position by the springs 43 to engage with the upper face of the abutment block and hold the latter in position against upward movement, the screw 36 then being adjustable to apply the required tension on the rolls. mechanism similar to that described may if desired be employed at both ends of the wringer. I

When it is desired to release the roll suddenly, as for example when a heavy clot of clothes is fed into the wringer or the fingers of the operator are accidentally inserted between the rolls, the upper roll may be instan- In this case also the screw Releasing taneously released to upward movement thereend frame.

relatively to the adjusting screw 36, so the locking dogs will move under the influence of their biasing springs into position to engage again the upper faces of the abutment block. Tension may then be applied to the rolls by the adjusting screws as desired.

As shown in Figs. 6 and 7, it will be observed that the laterally projecting flanges 18 are curved inwardly slightly forming shields for the ends of the rolls so as to guide the advancing clothes into the rolls and prevent them from gaining access to the space between the ends of the rolls and the supporting Clogging of the clothes into this space will therefore be largely avoided. Furthermore it will be noted that these flanges from smooth evenly curved continuations with the inner surface of the inner wall of the end frame. This smooth continuous surface permits clothes or other matter that may accidentally have gained access to the space between the rolls and the end frame to be readily carried along with the advancing clothes without-interference with the operation of the wringer and without injury to the clothes themselves.
