locking shoulders ii. The opposite end is secured by a safety device being along the same lines as shown in my application, Serial Number 45,279 in wmch'thermaremc wlldes M in the top bar with actuating bars I! along the front I The slides ll operate a rocking plate It swingingly mounted in the top of the top bar and having a trip end i1 adapted to engage the end of a latch l8. The latch I8 is pivoted on a pin l9. It has a. hook which en- 1 gages under a shoulder 2| in the side stile.. When the plate 16 is moved sidewise it releases the latch I8 and the latch releases the top bar and as the top bar'swings up the interlocking shoulders are unhooked and the pressure on the spring is thus released.

Clothes guides 22 are secured in'side brackets 23 at the front and rear of the wringer frame. These guides are directed to feed the clothes toward'the bite of the rolls. A trough 24 is argo ranged under the rolls in position to catch the water and this is discharged from this trough through an opening 25.

A-safety bar 26 is arranged in continuation of the guide forming a slight abutment at the upper end of the guide. This bar is pivotally mounted on pivot rods 21 and 28 extending-into the brackets 23, the rod 21 extending into the gear box to control the shifting mechanism for the gears. The inward end of the guide 22 has a depressed portion 29 leading into the trough and this makes a fairly close fit with the edge of the bar 28 when the front face of the bar is swung inwardly. The bar has a downwardly extending lip 30 at 'its inner edge which lip is adjacent to the lower roll. By exertingpressure on this ban-either toward the roll or away from the roll, the rod 21 is rocked. Thus the trip bar may be actuated by the operator when it is desired to disconnect the driving mechanism and it is automatically operated when the clothes wind around the lower roll by the engagement of the clothes with the projection 30. It also stops the power when the clothes follow .down the lower roll and engage the safety bar at the discharge side.

When the bar is operated it brings the gear mechanism to neutral and stops the roll. A preferred mechanism for this purpose is as follows: A shaft 32 is journaled in a bearing 33 in a gear box 34. I by a coupling 35. A beveled gear 36 is fixed on the shaft 32 and meshes with gears 31 and 32 journaled'on a drive shaft 39. A clutch member 40 is slidingly mounted on the shaft 39 and splined thereon. The ends of the memberv l0 and 55 The shaft 32 is connected with the shaft the faces of the gears 31 and 38 have interlocking detents and projections 4| forming clutch engaging means in the-usual manner. The member 40 has an annular rib 42 and a block 43 is provided with a groove engaging the rib 42. The block 43 has a cross slot 44 in which a crank pin 45 operates. The pin 45 is carried by a disc 48 and the disc is mounted on a shaft 41. A setting handle 48 is fixed on the shaft 41. By throwing this handle the crank is moved and consequently the clutch member is moved into engagement either with the upper gear, or the lower gear, thus driving the wringer in either direction. The disc has locking notches 49 which are adapted to be 15 engaged by pins 50 arranged in a cross slide 5|, The cross slide has slots 52 through which plates 53 formed in extension of the shafts 21 at the front and rear of the wringer extend. Springs 54 are secured at each side of a rock arm 55 extend- 20 ing from the disc 46 and yieldingly throw the either side, or in either direction, swings a plate 53 and this moves the latch iii to carry the pin 50 in engagement with the notch 49 out of such notch and thus releases the disc 48 which swings to its neutral position through the action of the spring 54 which has been put under tension. This immediately brings the parts to neutral and stops the wringer. It will be understood that the interlocking portions of the clutch have their en- 4|): gaging surfaces slightly inclined so that this assists in the disengaging movement when the lock is tripped.

The following mechanism is provided for releasing the trip mechanism so as to bring the 48. gear mechanism to neutral from a single osition. This is accomplished by providing cams 58 on the inner faces of upward projections of the slide 5|. These cams are adapted to operate in connection with cams 51 on a cross head 51a.

50 A pin 58 extends upwardly from the cross head through a bearing in the gear box and terminating with a press button 59. A spring 60 yieldingly holds the rod 58 upwardly.

When it is desired to release the driving mech- 55 anism the button 59 is merely depressed and the camming action forces the latch sidewise so as to bringthe pin 54 out of the locking notch and releases the mechanism. In the modification shown in Fig. 7 and followan ing the wringer is similar to that shown in the previous structure except that the safety device is 'omitted. The top bar has the interlocking shoulders I! at one end and at the opposite end has a re-setting device comprising a lever iii of 05 ui-shape in cross section pivotaily mounted on the top bar at 42. This lever 6| is pivotally connected with a link I by means of a pivot 85 and the link '3 is connected with the frame by a pivot 64. when the lever is thrown up the toggle mechanism is released and the top bar is released. I When brought down the top bar is forced down to position re-setting the pressure on the spring. I The wringer roll shafts. ear box and gear 'arrangemnt is the same as that in the preceding structure and the reversing clutch is also similar.

The actuating bars for controlling the gears"are,. however, slightly different. "Guides 66 are arranged on the front and rear of the frame. The guides have downward lips 41 which enter the trough. Atrip bar 44 is arranged at the front 5 and rear of the wringer. The bar is pivotally mounted on rods 4! and Il; the rodfl being carried through to the gearbox to actuate the setting of the gear mechanism. The bar 68 has a face II adapted through the camming action of the 10 clothes on this portion of the bar to depress the bar and accomplish a tripping action. The bar 88 also has a lip I2 which is in position to be engaged by clothes wrapping on the roll, or clothes jamming at the discharge side in which event the 1 trip bar is rocked and the gear driving mechanism thrown to neutral.

In order that the trip bar may be actuated by clothes winding 9n tlieppper roll levers I3 are arran ed at eachside of the wringer and engages 20 the ends of the lip I2. These levers are pivoted at I4 and have cross bars I5 extending across the upper roll in position to be engaged by lf he clothes 7 if wrapped on the upper roll., v j

The tripping mechanism for controlling the 25 ear clutch is modified from that shown in the preceding figures and is as follows: A shaft I6 is journalecun iggg earbgxand carries a disc 11. This disc 'has a crank pin I8 operating in the grooves 44 of the block operating on the clutch 30 member. The disc has an arm ID from which a. handle so extends-the handleexliellflhgli lifough a slot 8| in the wall of the gear box. By oprating this handle the crank can be operated and the clutch member thrown up or down to drive 35 the wringer in either direction, or may be fixed at neutral so as to disengage the driving mechanism.

An arm 82 is arranged on the disc I1 and springs 83 operate onv this arm to yieldingly o draw the crank to neutral position when the parts are released.

Levers 84 are fixed on the shafts 69 and rock with these shafts. These levers 84 are U-shaped, the sides being connected only at the ends by a cross plate 85. The two levers are connected together at reverse ends by a link 44, the link 86 being connected to the outer'strap only of the levers 84 by pivot pins 81. This link compels the pivoted levers to move together, opening the top 0 or closing the toptogether. A trip plate 88 is mounted on the arm I8, its ends extending between the waiis of the levers 84. Each end of the trip plate is provided with a stop shoulder as which is adapted to engage the end of the connecting strap when the trip plate 88 is thrown in either direction through the action of the arm 19. It will be seen that when the handle is operated and the arm I! thrown the trip plate is swung so as to bring the shoulder 89 out of the lever 84 and the springs 43 which have been put under tension snap this lever in behind the stop and lock the trip plate and consequently the arm I9 and crank in the set. position. When, however, either rod 44 is by a downward, or u inwardmovement of thetrip plate", the lever 64 is rocked so as to draw the strap 85 away from the shoulder 89 and thus release the trip bar and with it the rock arm I. and the clutch.

A release button 94 is connected by a post 9| 7 and the post M has a cross head 92. The ends of the cross head are slotted at O3 and pins, 94 extend through these slots into the inner walls of the levers 84. By pressing down on the button 90 the cross head operating on the upper ends of u the levers 8G rocks them inwardly and disengages the shoulders 89, thus immediately permitting the parts, under the action of the springs, to spring to neutral. It will be seen, therefore, that the operator by exerting downward pressure, or

inward pressure, on the actuating bar can stop.

the wringer and the operator then: can, if desired, immediately reverse the wringer and disengage the hand; It will also be noted that any wrapping, or jamming of the clothes also actuates the bar and throws the driving mechanism into neutral position.
