CLOTHES WRING-ER Application led November 23, 1928.

My invention relates to improvements in clothes wringers.

The objects of my invention are: 1. To provide improved means for main j taining the variable compression between a pair of wringer rolls.

2. To provide improved means for simultaneously driving a pair of wringei' rolls variably spaced apart.

3. To provide resilient driving means f or wringers which will permit the use of adjacent soft-faced rolls and avoid undue deflection of the rolls during the wringing operation.

4. To provide means which will allow the passage of buttons and other objects through a pair of wringer rolls without breakage, or which will largely avoid breakage of buttons, etc., passing through the rolls.

5. To provide improved means for disengaging the rolls of a wringer and to automatically separate them when disengaged.

6. To provide a two-part frame for a wringer, with means for securing the two parts in operable position and means for manually unlatching them and automatically disengaging the rolls when unlatelied.

I attain these objects by the means illustrated in the accompanying drawings, in which,-

with the adjoining portion of the frame broken away.

Figure 9 is an enlarged detail showing the hub or bo-ss, 48, with the latch bar passing through it shown in section.

My wringer comprises a lower frame, 13, an upper frame, 12, seated upon the lower frame, which in turn is seated upon a flange,

23, formed upon the top of the supporting column oi' shaft housing, 24.

The lower frame, 13, is provided with a sleeve, 25, which extends onto the supporting column, 24, and secures the wringer firmly thereon. The lower frame, 13 may be secured upon the supporting column in a fixed position or adjustably mounted thereon as desired.

rlhe lower frame has formed integral therewith a flange, 16, and the upper frame has formed integral therewith, a flange, 14. These flanges form a joint at 15, at which the upper frame may be swung around upon the lower frame.

A drive shaft, 26, is mounted in the supporting column, 24, and` extends upwardly through the top of the upperframe, 12, into the boss, 6, formed integral with the upper frame.

A bevel gear, 20, is secured upon the shaft, 26, within the lower frame, 13, and meshes with a bevel gear,19, mounted upon one end of the ioll shaft, 35, which carries the lower roll, 40. The shaft, 35, is preferably mounted upon wood bearings, 36 and 46, secured within the lower frame, 13.

At the upper end of the shaft, 26, a bevel gear, 8, is secured by a spline or feather, which permits it to slide longitudinally upon the shaft, 26. The bevel gear, 8, meshes with a corresponding bevel gear, 9, mounted upon one end of the shaft, 30, which carries the upper roll, 28. The shaft, 30, is preferably mounted upon wooden bearing blocks, 5 and 27, secured in the upper frame.

A compression spring, 7, is secured around the upper end of the shaft, 26, between the bevel gear, 8, and the boss, 6, and exerts a pressure downwardly upon the bevel gear, 8.

A curved bar spring, 4, is secured within the upper frame having its ends resting upon CTI the bearing blocks, 5 and 27, and its upwardly curved middle portion bearing against the lower end of an adjusting screw, 2, to which is united a knob or wheel, 1. rIhe adjusting screw is threaded into the boss, 3, which is formed integral with the upper plate of the upper frame, 12.

At the left end of the upper frame, a small extension, 47 a, is fo-rmed integral with the upper frame with a hole or bore extending vertically through it in which is slidingly mounted a latch bar, 47, the lower end of which passes through a similar extension, 48, formed upon the end of the frame, 12. The extreme lower end of the bar, 47, is normally engaged by a pair of detente, 50, for-med integral with the lower frame, 13, but is provided with a notch, 49, so that when the bar, 47, is pushed downwardly, the notch, 49, will allow it to clear the detents, 50, and permit the upper frame to be swung around on the shaft, 26, as a pivot, thus freeing the upper and lower rolls from engagement and releasing any object which might be caught between them.

The knob, 51, is secured to the top of the bar, 47, and a compression spring, 51a, is mounted around the rod, 47, between the knob, 51, and the extension, 47a.

The lower roll, 40, preferably comprises a relatively hard core with a relatively softsurfaced portion, 34, secured thereto, the core being much thicker relatively than the surface portion.

The upper roll, Q8, is preferably formed of relatively soft material, with a small relatively hard core, 29, secured at the center thereof and mounted upon the shaft, 30.

Then two soft rolls are used in juxtaposition, if they exert sufficient pressure upon each other to press water out of the clothing passing between them `and if both of them a re driven at the same speed, there is a tendency for the soft material of which the rolls are r composed, to be distorted and deflected to a considerable extent and this distortion will soon greatly impair the rolls. But in order to prevent breakage or bending of buttons. ete., attached to the clothing passing through the wringer, it is important to have a relatively soft surface for both rolls and to secure the greatest efficiency in driving water out of the clothes, both rolls should be driven at the same speed.

I therefore secure the soft surfaces necessary to prevent breakage or bending of buttons, etc., and at the same time prevent distortion and deflection of the soft material comprising the rolls, by forming one of my rolls with a large hard core carrying a relatively soft, thin, outer portion mounted thereon and suitably secured to the core.

In the operation of my device, the upper frame of the wringer is latched in its normal position above the lower frame. The drive shaft, 26, is then operated through its connections with the motor or whatever driving means are provided, and carries with it the bevel gears, 8 and 20. These in turn drive the gears, 9 and 19, and thereby turn the rolls, 40 and 28.

The bevel gears, 19 and 20, are in fixed relation to each other and the compression, spring, 7, maintains he bevel gears, 8 and 9, in mesh.

The spring, 4, holds the faces of the rolls, 40 and 28, in contact and as the rolls are turned, the clothes to be dried are fed between the rolls. The soft upper roll and the soft face of the lower roll allow a considerable degree of compression thereof and will permit buttons or other hard substances, to sink into the rolls without injury, the resilient surfaces of the rolls resuming their normal positions after the buttons are past.

In case a thick bunch of clothes is fed to the rolls, the soft faces of the rolls will give to a considerable extent without injury and thereby avoid blocking the rolls.

Likewise, if a hand is accidentally caught between the rolls, the rolls will give suiiiciently to avoid severe injury. In case either a bunch of clothes or a hand is caught between the rolls, it may be disengaged by pressing downwardly on the knob, 51, which will unlatch the upper frame Jfrom the lower frame and allow the upper frame to revolve around the shaft, 26, as a pivot so as to release the clothes or hand from the rolls.

I.Vlien the obstruction has been thus taken from the rolls, the upper frame may be returned to its normal position upon the lower frame and latched in position thereon.

It is obvious that whenever the latch is released while the rolls are in motion, the movement of the rolls will tend to separate them laterally and this tendency will be aided by the pressure of the clothes or hand between the rolls.
