' 'WRINGER y Application led November 30, 1926. Serial No. 151,805.

My invention which relates toa wringer comprisingl adJustable means, having operative relation withthe rolls for exerting pres-v sure on them or inoperative relation with them for'A releasing the pressure, and driving means having operativerelation with the rolls for their rotation or inoperative relation with them for the stoppage of their rotation is provided with means for simultaneously controlling the action of both the pressure exerting means and the driving means.

Various modifications in the structural details of the wringer are within the scope of the invention, and in the apparatus which I have made the wringer is constructed witha cover part which includes a pressure exertmg spring or springs secured 1n operative or pressure exerting relation with the rolls by the movement of a sliding locking bar in one a direction or released from pressure exertf ing relation with the rolls'by the movement of the locking bar in the opposite direction. The driving means consist of -a driving shaft provided with a driving bevel gear wheel and a driven shaft provided with two driven bevel gear wheels selectively movable into and out of mesh with the driving gear wheel. An operable control is provided for the drivu en gear wheels which is actuated by the locking bar to bring these driven gear wheels'to a neutral position with the driving gear `wheel when the locking bar is moved to release the cover part for relieving the pressure on the rolls.

For an understanding ofmy inventioireference is to be had to the following description and accompanying drawings, in which:

Fig. 1 is a fragmentary vertical sectional elevation of a wringer constructed according to this invention, showing the driving means and the means for controlling the action of the pressure exerting means and the driving means, l

Fig. 2 is a plan vievvof the Wringer and driving head,

Fig. 3 is a side elevation of the wringer and driving head shown in Fig. 2,

Fig. 4 is a sectional elevation of the wringer shown in Figs. 2 and 3, and

Fig. 5 is a perspective view of the control for the driving mechanism.

Like charactersof reference refer to like The wringer 25 bolted or otherwise fas- .head on the standard.

` tened to the driving head 1, which may be of two of the opposite sides of the housing aretwo horizontally disposed bearings 2, 2a, the axes of which are in horizontal alignment. Slidably and rotatably journalled in the bearings are the arbors', 3, for the bevel gear wheels 4 and 5. The arbors 3, 3a, are bored and the driven shaft 6 is mounted in their bores. The bevel gear wheels 4 and 5 are keyed or otherwise secured to the shaft for causing' its rotation, when motion is imparted to either one of the bevel gear wheels. Loosely encircling the shaft between, and engaging, the bevel gear wheel 4 and 5 is a sleeve 7 and attached to or forming part of the sleeve 7 is a plate 8 having an elongated slot V9. Journalled yat the top of the driving head is a mandrel 10 and fixed to the mandrel is a disc 11, the center of which is eccentric to the axis of the mandrel. Extending from the disc 11 is a pin 12 the axis of which is eccentric to the centerof the disc and this pin is entered in the slot 9. At the outer end of the mandrel 10 is the wringer reverse lever 13 for rotating the mandrel, eccentric disc and shifts the sleeve 7, and-shaft 6 axially to of mesh with the driving bevel gear wheel 14. The driving shaft 15, which is rotated by motion transmitted from any suitable source of power, is enclosed in a vertical standard 16 and the arbor 17 of the bevel gear wheel` 14 is entered through an aperture 18 in the bottom side of. the housing to extend below the driving head and into the upper end of the standard to receive the upper end of the driving shaft. The driving shaft is entered in a rectangular socket in ther arbor 17 for f (lll The rotation of the disc 11 and pin 12 l causing the rotation of the bevel gear wheel 14 during the revolution of the'shaft. On the outer'side of the bottom of the housing or driving headis a boss 19, in which is entered and which'snugly fits the upper end ofl the standard, for the assembly of the driving This construction provides for the rotatable adjustmentof the driving head and wringer.

In the upper end of the standard 16 are a' plurality of keepers 2Q which may take the form of apertures or `inidentations, and 1n the present construction these keepers 2Q consist of notches extending downwardly lnto the` standard from its top edge. Slid'ably entered through ktheboss 19a is a locking bolt 2l for engagement with any one of the keepers 20, for effectively but releasably securing the driving head and wringer in their selected rotatable adjustment and connected to the locking bolt 21, for its actuation, is a rod 22 which extends from the locking bolt to the opposite-side ofthe Wringer 25.-

' For the attachment ofthe-wringer to the driving head l, a plate 24 is integrally formed with the bearing 2a and the main frame-25 of the wringer is bolted or otherwise secured to this plate.1 The wringer roll 26 is journalled in the main frame at or near the bottom of the wringer and the shaft 27 of the wringer roll extends through the main frame into the bearing 2a. Pinned to the shaft 27 is a clutch member. 28 which extends from the shaft a distance greater than the length of movement of the bevel gear wheels 4 and 5. The shaft 6 is formed with a clutch member 29 which-enters, or engages with, the clutch member 28, for 'causing the rotation of the shaft 27 and wringer roll 26, as the shaft 6 revolves. To

3U accommodate the clutch members 28 and-29,

the bore of the arborv 3 is enlarged, asshown at 30, and this enlargement extends inwardly fronithe end of the arbor to the` inner end of theclutch member 29. When the bevel gear wheels 4 and 5 are adjusted to move the bevel gear wheel 5 into mesh with the drivingbevel gear .Wheel 14, as shown in-full -lines in Fig. l, and the bevel gearfwheel 4 outof mesh with it, as shown in full lines in the l tated in one direction.- During this adjust-v '45 28, but not sufficiently to disengage the clutchV 'members When the bevel gear'wheels 4 and 5 are adjusted to move the bevel gear wheel j same figure, motion is transmittedl from the bevel gear wheels 14 and 5 and shaft 6 tothe v wringer roll 26 by means of the clutch member-S28 and 29, and the wringer roll is roment of the bevel gear wheels the clutch member 29 moves partly out of the clutch ymember 4 into mesh with the driving bevel gear wheel 14, and the bevel gear Wheel 5 out of mesh with it, the rotation' of the wringer roll 26 is reversed. When the bevel gear wheels 4 'l and 5 are moved to a neutral position, Fas

shown in dotted lines 1,neitherof them isin mesh-With the bevel gear wheel 14, and

' ,the rotation of the wringer roll 26 is then i W'ringer is not interrupted by the rotatable.y

the journals of this roll are pressure, or journal, blocks 32.- Hinged to the top of the main frame 25 is the cover 33 provided' with a down-turnedv flange 34, and extending through the `flange 34 are two supporting members 35, the axes of which are parallel cover 33 is a leaf spring 36, the ends of which loosely rest on' the supporting members 35 and have vertical movement in an upward direction b-ut their movement in a downward direction is limited by their engagement with the bolts. Centrally journalled inthe top of the cover is the axle 37 of a rotatable cam or eccentrically mounted disc 38, and tted on the end of the axle, beyond the cover 33, is a crank 39. The disc continuously engages the spring 36 andl is rotated to vary the tension of the spring. TheV pressure blocks 32 extend above the supporting members 35 when the cover is i fa closed position andnormally lift the spri g from the supporting members, so thatwhen the cover is 'closed and secured in its closed position, the spring is at all times in pressure exerting relation with the blocks and by means of the latter with the wringer rolls. When the vdisc 38 is rotated to the' position shown in dotted linesv in Fig. 4, the springk 36 is tensioned to the minimum degree and when the' disc is turned Wit-h the journals of the roll'3l. Within the to the position shown 'in full lines in Fig. 4,-

the spring is tensioned to the maximum degree. A, v .x

This construction provides a simple'and rapid adjustment for correctly varying the pressure on the rolls.v

The disc- 38 is rotated slightly beyond its j central position when applying the maximum pressure ofthe' spring, and the crank 39 then moves to the position shown in full lines in Fig. 4 andengages the lcover 33. The disc is preventedv from inadvertently moving from thisV position ,in one direction and releasingV the pressure during the operation of the Wringer rolls, by the engagement of the crank 39 with/'the cover, and is prevented from in` atvertently movinggin the other .directiony by 1 engaging relationwith the spring and lb the wight of the crank. y

`Other types'of springs and tension devices I may bejemployed in lieu of the specific type 'shown and described' and it is not intended that the invention should be limited to this specific construction. f f

The cover, including the pressure exerting means, are for convenience, termed the 'cover part, and for holding the cover part in operative relation with the wringer rolls', a, locking bar 40 is rerprocatlgly attached to the i125' l main frame 25. This lockingv bar is formed ywith elongated slots 41 through which are iis entered headed bolts or studs 42 projecting j -I `from the main frame 25, for slidably securing the locking bar to it and for guiding the locking bar duringA its reciprocating move` ment. The locking bar is provided with two hooks 43 spaced to come into engagement with two projections 44 onthe cover 33, and by their engagement. with the projections, securelyl lock the cover in its closed position and maintain the spring in pressure exerting relation With the rolls. The hooks on the locking bar are comparatively long and so shaped that they draw the hinged cover down to its locked position and transfer the pressure of the spring from the supporting members 35 to .the pressure blocks 32.

At the bottom of each hook 43 is a slight 4recess into which the projections 44 drop when the locking bar is moved to the limit of its locking position, for preventing the hooks from inadvertent displacement from` the projections 44. lExtending horizontally from the locking bar is a lug 45 formed with a slot- 46 through which is entered, a wringer release lever 47, the lower end of which is fulcrumed at 48 to the main frame 25. The actuation of the lever 47 operating through the slot 46 effects the movement of the locking bar for the engagement of the hooks 43 with the projections 44 and for the release o-f the hooks from them. The release of the locking bar from the projections immediately releases the pressure of the cover part on the Wringer rolls. This release of pressure does not, however, in the case of accident, for example if an article of clothing is winding on the lower roll, correct the trouble and to do so itis necessary that the rotation of the rolls should be stopped. Heretofore it has been customary to effect this stoppage by an additional operation which necessarily causes confusion and loss of time.v To avoid this ,confusion and loss of time, the locking bar 40 is formed with an arm 49 pivotally connected with a reversing lever control 50. This control takes the form of a forked link having two projections 52 which engage cam shaped lugs 53 extending laterally fprom the wringer reverse lever 13. The control has a sliding action on the top of the driving head or housing l, and the .locking bar, when moved to its operative position for the engagement of the hooks 43 with the projections 44,- pushes the control 50 in the direction of arrow (Fig.' 5). The forks 54 of the control 50 are located one at each side of the mandrel 10 and the s ace between the forks is sufficient to enable t em to freely pass the mandrel and the hub 55 of the wringer reverse lever 13 as the cons trol moves during its actuation. vThe projections 52 are placed at or near the ends of the forks 54 and when the control is pressed to the limit of movement in the direction of arrow (Fi 5) the projections 52 are entirely free ig-rom contact with the cam shaped lugs 53. The wringer reverse lever 13 can then be rotated manually to selectively move 'eithervof the bevel gear wheels 4 or 5 into mesh with .thel bevel gear wheel 14, or to bring the bevel gear wheels 4 and 5 to a neutral position without imparting movement to the locking bar.

In this way the driving mechanism can be controlled for the rotation, reversing, and

stoppage, of the wringer'rolls without actuwith the lugs 53 irrespective of the positiony of the wringer reverse lever 13 when the control is actuated. The engagement of the projections 52 with the lugs 53 during the continued action of the locking bar, rotates the wringer reverse lever 13, mandrel and eccentric disc, to the position shown in Fig. 5, and this rotation of these parts brings both the bevel gear wheels 4 and 5 to the neutral position of the driving mechanism, in which position neither of the bevel gear Wheels 4 and 5 is in mesh with the bevel gear wheel 14 and no driving motion is transmitted to the wringer roll 26. The actuation of the control 50 is simultaneous with the actuation of the locking'bar 40 to release the cover part and consequently the rotationof the Wringer rolls is stopped immediately the pressure exertedon the rolls is relieved.
