REVERSE POWER-ACTUATED RELEASE FOR CLOTHES-WRINGERS.

Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed March 2, 1917. Serial No. 152,035.

To all whom it may concern:

B it lmown that I EDGAR B. STOCKING, a citizen of the United States, residin at Washington, in the District of Colum 1a, have invented certain new 'and useful Improvements in Reverse Power-Actuated Releases for Clothes-Wringers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention has relation to clothes wringers and one of its main objects is to provide means for quickly .releasmg the pressure existing between the wringer rolls when in operation by manipulating the handle or crank by which the rolls are driven.

Another ob]ect is to restore the pressure Another object of the invention is to embody it in such devices as can be readlly applied to an ordinary wringer without changing any of its principal parts 1n any material respect. p

Another purpose in view is to avold .a

release of the pressurebetween the rolls. Other objects and advantages of the vention will appear inthe following descnption and the novel features thereof will be particularly pointed out in the claims.

In the accompanying drawmg, 1n WlllCh like parts are indicated by like numerals: Figure 1 is a feed-side elevation; w1th a central portion broken out and portions 1n vertical section of an ordinary wringer to which the invention is applied, the pressure I bein on.

F1g. 2 is an end elevation of Fig. 1, the crank shaft being-in section. I

Fig. 3 is a similarend elevation, the parts being in the positions assumed when the pressure is released and also in position to restore pressure.

Fig. 4 is a detall in perspective of an endless track or guide for the resetting device. In the drawing I have shown an. ordinary wringer comprising standards 1, in which is mounted a roll 2 adapted'to be driven by a crank or handle 3 mounted on the shaft of the roll which drives in turn the upper roll 4 through the medium of the gears 5. The rolls are held under pressure by a spring 6 through the medium of a cross bar 7 carrymg pressure screws 8 for adjusting the pres-,v sure in the usual manner of clothes wringers of this type now 'in use.

In the following description the usual known construction of a quick release comprises the niovable cross-bar, screws and sprlngs andsome device such as 'a hook or a keeper associated with the cross-bar to hold or retain the pressure and such elements are herein included in the term pressuredevice, and with some .releasing device constitute an operative structure.

The invention comprises a pressure device 9 WlllCh in this instance is a rigid plate secured to the end of the cross-bar 7 and is limited in its downward and upward movements by a pin or pins 10 seated in the standard and, arranged within a recess or recesses 11 formed in the edge or edges of the device 9. Said device also is provided with a pin 12 with which a hook or pressure releasing device 13 cooperates to-retain pressure and to release the same as hereinafter described.

The hook 13 is pivotedpreferably below the lower gear and at a point in line with the pin 12 as at 14 to preserve alinement and to reduce the friction of device 9 upon the pin or pins 10 which would occur were the hook 13 pivoted elsewhere. Between its pivoted and free ends the hook is provided with an extension 15 against which anarm 16 of a pawl 17 contacts; the pawl being into the path of the teeth of the lower gear 5 while a spring 19 keeps the tive relation with said gear.

In the shaft of the lower roll 2 is a pin 20 and in the inner face of the hub of the crank or handle 3 is a recess 21 which embraces said pin and preferably extends from one quarter to one-third of the circumference of the hub. The recess 21 is the only change made in some wringers as a pin and pin-slot are common means for mounting a handle on a shaft in some wringers. A recess as 21 gives the-handle, or crank a limited moi'ement without rotating the'shaft and roll.

Upon the plate 9 there is pivoted at 22 a resetting lever 23 comprising a lateral arm In the standard are seated obstructions in the form of pins 28*29 and 30 arranged to co6perate with the resetting lever as hereinafter described.

An endless track or guide 31 is located upon or in the standard to receive the pin 25 ofthe'resetting lever 23 and comprises an unobstructed rectangular continuous passage 32 adapted to give the free end of the resetting ,lever. 23 a four direct1on.movement. While the track or 'guide may be formed in the standard it is preferable to form it of metal and set it in the standard and secure the same bysuitable means as screws in a flange 33 formed thereon.

The operation, of the invention is as follows: i a

Assuming the parts to be imder pressure as shown in. Figs. l and 2, the operation of wringing clothes takes place by rotatmg the roll 2,1in the direction indicated by the arrow in Fig. 2, the recess 21 in the hub.

of thehandle or crank pressing against what would be the lower side of pin 20 in Fig. 1 and the pawl 17v riding lnoperatlvely over the teeth of the gear 5 the arm 16 of the pawl vibrating inoperatively between the extension 15 and the body of the hook 13.

Now in case of abnormal feeding or of the entrance of the fingers or hand of an operator between the rolls the natural act of reversing the crank carries the opposlte end of the recess 21 against the opposite side of the pin 20 and instantly pushes the pawl 17 downwardly and the arm 16 outwardly against the extension 15 forcing the hook 13 against the tension of spring 34 oif from the pin 12. of the device 9 when the'upper roll 4 is instantly released from the pressure of the springs 6. i It Will be noted that in this natural reversal of the handle or crank the hand or fingers of the operator are only subjected to a rolling pressure when being released by reason of the='recess 21 which permitssaid reversal without rotating the shaft or the roll in a direction to draw the fingers between the rolls so that instant release of pressure is obtalned without causing increased pain or in ury.

During the'release of pressure just described theresetting devices have been put in position to be operative slmply by resumlng rotation of the crank as in wringing.

from pin 12 of device 9 said device rises with the cross-bar 7 and carries with it upwardly free from contact "with gear 5 the resetting lever '23, the pin riding in the vertical outside track. As thearm 24 strikes pin 28 it forces pin 25 inwardly along the upper cross track of guide and brings the tooth 26 of the lever-into mesh with the gear as-shown in Fig. 3. Now'by turning the crank in the direction of wringing the resetting lever draws down device 9 and the cross-bar, the pin 25 riding-the inner vertical track, thus holding the tooth in mesh with the gear, until the spring'34 forces the hook 13 over the pin 12 whenthe pin 29 contacting with the lower edge of arm 24 causes pin 25 to ride outwardlyin the bottom cross track of the guide thus forcing tooth 26 out of .mesh with gear 5. Simply to insure this movement of the pin 25 and free the tooth of the lever 23 from the gear the cam face 27 and pin 30 are provided.

In the'above manner and. by the above means a release and resetting of pressure is accomplished by a simple and natural reversing of the handle crank of an ordinary wringer. It is understood of course. that the means above described are duplicated at each erative connection with the gear at each end ofthe roll which gear is nonrotatably vided with any well known reversing means.
