Speciilcation of Letters Patent.

Application led April 9, 1913. Serial No. 760,013.

T0 all 'whom it may concern.'

Be it known that I, WII'LIAM ROBERTSON, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Wringers, of which the following is a specification.

' This invention relates to wringers and consists in certain improvements in the construction thereof as' will be hereinafter fully described and pointed out in the claims.

In the use of'wringers, especially power- Wringers, it has become desirable to have some means for instantly releasing the pressure on the rolls so as to o'bviate the danger of injury to an operator who may get caught by the rolls and also to release any materia-lI that may be wound around the rolls.

The object of the invention is to provide a simple and eiiicient mechanism for this type of wringer.

The invention is illustrated in the accompanying drawings as follows Figure 1 is a plan view. of the wringer. Fig. 2 a side elevation, partly in section on the line 2 2 in Fig. 3. Fig. 3 an end elevation, partly insection on the line 3-3 in Fig. 1. Fig. 4 is a section on the line 4-4 in Fig. 2, the view being toward the top of the wringer.

1 and 2 mark the side stiles of the frame, 3 the groove slot formed in the side stiles, 4 the bearings mounted in the

slots

3, 5 and 6 the shafts for the rolls which are journaled in the bearings, and 7 and 8 the rolls carried by the shafts 5 and 6. The shaft 6 has the extension 9 which may be attached to a power mechanism in any manner desired. Springs 10 are arranged in the slots 3 and are designed to exert pressure on the rolls. A presser bar 11 has the metal ends resting on the tops of the springs. A top rail 13 is arranged between the sides of the stiles and rests on the shoulders 14 at each side of the slots 3. The top rail is clamped between the sides of the stiles by -the bolts 15. This structure so far as described is one in common use.

The top rail has the perforations 16 concentric with the springs 10. Each of these perforations has a lateral extension 17 forming through the rail what -is commonly known as a key-hole slot. A plate 18 is secured to the bottom of the rail one for each end of the rail and this. has the perforation and extension- 19 forming a key-hole slot in continuation of -the perforation 16 and extension 17. A nut 20 is slidingly and rotaf tively mounted in the perforation 16. This has a flange 21 on its upper end which limits its downward movement and the lugs or projection 22 of a size to pass through the extension 17 and projects into the slot 19.

The projection is so arranged that when thev nut is provided with an arm 24 and the lever 23 and arm 24 are connected by a link 25 extending across the top of the wringer. ByA

swinging one of the nuts by means of the lever 23 both nuts are brought to the position shown in dottedy lines in Fig. 1 `and' are thus locked in place. By swinging them to the -positionbringing the projections into alinement with the extensions 19, the nuts are instantly released and can slide upwardly in the perforations. A stop 26 is arranged on one of the nuts in position to come into contact with the link 25. When brought to this position, the parts are lockedA as shown in Fig. 1. Pressure screws 27 extend through the nuts 2O and operate against the pressure bar 11 to adjust the springs 10 in the ordinary manner.

It will be understood that in the normal use of the wringer, the nuts remain in the locked position andthe wringer is used asa wringer is ordinarily used. When, however, an accident occurs and it is desired to release the pressure onv the rolls the lever 23 is swung in the direction of the dotted line Fig. 1 and this brings the projections into alinement with the extensions 17 and the pressure on the springs is instantly released. The pressure screws 27 may then be turned out and the nuts 20 can then be passed through the perforations and readily locked in position and pressure is then again Aapplied through the operation of the screws.

It Will be observed that with this structure there is a positive lock of the nuts and at the same time there is a great leverage with relation to the catch so as to overcome the friction exerted by the catchI on the plate. It Will be understood that a considerable pressure is exerted by the screws on the springs and that this leverage in moving the catch is desirable in making an easy working release. This is of great importance when it is understood that this release is to be accomplished where :the operator is caught with great rapidity andloitten at an inconvenient position. It will also be observed that the rail is. firmly clamped so asv to support the frame and that the parts are verysimple in their construction adding but little to the weight of the ordinary wringer.

What I claim as new is 1. In a clothes wringer, the combination of a presser roll.; a frame in which the rolls are mounted comprising as a permanent member of the frame a top rail, said top rail having` a key-hole slot therein with a substantially flat surface on the under side of the rail adjacent to the slot; a springr eX- erting pressure on the roll; a rotary catch .arranged in said slot, said catch having a lateral projection thereon adapted to engage the underside surface of the rail when the catch is turned, said catch being in the form of a nut for holding the spring yunder pressure, the pressure being in the direction of the axis' of the catch; and a presser screw extending through the catch vor adjusting the pressure on the spring. l

2. In a clothes wringer, the combination of presser rolls; a frame in which the rolls are mounted comprising a top rai-.1; springs arranged at each end of the rolls and 'ex-V Y tending upwardly; rotary catches swiveled in the top rails for holdingthe springs under pressure, the pressure on the catch being in an axial direction, saidcatch having projections interlockingwith the rail and adapted to be released by a rotary motion; a screw arranged in each catch and each adapted to adjust one of the springs; and a connecting means between said catches whereby they may bek rotated simultaneously. v v

3. In a clothes-wringen the combination of presser rolls; a frame comprising. side stiles in which the rolls are mounted and a top rail; springs arranged at each end lof the rolls and extending upwardly' in the side Stiles; nuts rotatively and slidingly mounted in the r'ail above the springs, said nuts having interlocking projections thereon; means on the rail locking said projections and adapted to release the nuts when the nuts are rotated; screws in the nuts adjusting the pressure on the springs; a link connecting said nuts whereby they maybe simultaneously operated; and a stop. on one of the nuts co-acting with the link to stop the nut in locking position.

In testimony whereof I have hereunto set` my hand in the presence of two subscribing witnesses.
