SAFETY DEVICE FOR CLOTHES WRENGER/Sf Application filed November 13, 1923. Serial No. 674,550.

To a-ZZ whom t may concern.'

Be it known that we, CHARLES W. YOUNG and EUGENE F. YOUNG, citizens of the United States, and residents, respectively,

a of the city of New York, borough of Manhattan, in the -county and State of New frork, and North Bergen, in the county ot Hudson and State of, New Jersey, have invented a new and Improved Safety Devicev for Clothes Wringers, of which the following is a full, clear, and exact description This invention relates to a safety device for clothes 'wringers an object ofthe invention is to provide a simple, durable, eHicient device which can be readily attached to any standard type ot wringer for the purpose of stopping the operation of the wringer when the danger of the operators hands getting between the rolls is imminent. 2@ Another object concerns the provisionot 1 a simple system of levers, a portion of which is disposed adjacent the path oit entry of the clothes to the roller and another portion of which is connected, preferably, to a mo- The invention is illustrated in the draws' ings, of which Figure l is a front elevation of a wringer showing my invention attached thereto; l Fig. 2 is a section taken on the line 2 2 of Fig. l showing 'the motor controlling switch in the position in which the switch is closed;

Fig. 3 is a similar 'View showing the motor controlling switch in the open position;

Fig. 4- is a section taken on the line 4 4 of Fig. 2;

Fig. 5 is a section taken on the line 5 5 ot' Fig. 1; 1

Fig. 6 is an enlarged section taken through the rollers'of the wringer and illustrating the manner in which one Lend of the safety bar is detachable romthe Wringer frame; 'and 55 Fig. 7 is an enlarged sectional view showtor controlling means whereby the operation ing the manner of attaching the safety bar to the other levers in the system.

rFhe forni of the invention shown in the drawings is a preferred form, although it 4is understood that modifications in the construction and arrangement oi the parts and ,this condition can be removed to prevent the breakage of the parts. Furthermore, the bar is so disposed that if the hand of the operator approaches too closely yin the line oit contact of the rollers,the hand will naturally strike the bar and cause the operation of the system of levers with which the bar is associated, so that the motor controlling means will be operated by such contact.

Preferably, safety bars are disposed on both sides ot' the rollers7 the bars and the linkages connecting them to a common motor controlling element being substantially duplicates "of each other. For this reason the description of only one system will be necessary, although it is clearly indicated in the drawings that two sets of elements are provided.- l

As shown in Figs. l to 6, one end of the bar l is offset, as'indicated at 2, so that the major portion of the length of the bar is disposed in a different line than the end. rlihis end of the baris engaged in a slot 3 in a plate 4. Fastened to the side of the wringer frame 5 a pivoted latch plate 6 is attached to the plate 4 and provided with a slot 7 thereon whichv is disposed or points in the opposite direction to that in which the slot 3 points, so that as the pivoted plate 6 is swung upwardly into the position shown in Fig. 6 the end 2 of the bar l is held between the plates 4 and 6 to act asY a bearing, permitting the main portion l of the bar t9 swing around its ofset end.

The other end of the bar, as shown in Figs. 1 and 7, is connected to the lower end of a pivoted-plate 8. This pla-te 8 is pivoted Q11 a screw 9 to the other side of the frame 5 of the wringer, the-,upper end of this plate connected by a bent bar 9a to the lower end of a stem 10 which carries one element 11 of a switch. The bar 9a connected to the upper end of the pivoted plate 8 is bent around the wringer frame to a point outside of the same in line with the stem of the switch. The end of this bent bar is provided with a slot 12 in which a pin 13 on the stem 10 is adapted to ride. rlhe stem 10 projects linto a switch boX 14 containing circuit elements 15 and 16 which are bridged by the contact or switch element 11 in a certain position thereof.

In the normal position of the parts the bar 1 hangs straight down from its pivot points, and the plate 8 is disposed substantially vertical adjacent the inside of the wringer frame, consequently the connecting links between the pivoted plate 8 and the switch stem 10 are substantially horizontal, as shown in Fig. 2, inwhich position the stem and switch elements are in the position shown with the circuit closed to the motor. However, it can be readily observed from a consideration of the drawings, whenever anything contacts with the main portion of bar 1 which lies below the pivot points of said bar, this portion of the bar will tend to be moved inwardly and the upper end of the plate 8 willv tend to move outwardly to the position shown in Fig. 8, and this outward movement will cause the outer ends of the bent bar 9a to swing upwardly and in so doing push the stem 10 of the switch upward to disengage the Contact elements and thereby open the circuit to the motor. It will be observed that, as previously stated, there are two bars and connecting sets of linkages on the opposite sides of thewringer, both co-operating with the stem 10.

It will be observed that the switch is so connected to the bars on either side of the roll that when the bars are either moved inwardly or outwardly the switch is opened. 'When the bars are moved inwardly by reason of the contact therewith of the hands of the operator, the switch is moved upward. On the other hand, if the clothes become wrapped around the roll, as this wrapping increases in diameter it will come in contact with the inside of the bars and move them outwardly. This will cause the switch to move downward and become opened. It is to be noted, therefore, that the switch can move in either direction from the normal position, depending upon the direction which the bars are moved.

It will be noted that a handle 17 projects through a slot in the switch box 14 s'o that the switch can be moved manually when dej sired. It will also be noted that the latch plate 6 is provided with a knob 18 whereby 1t can be readily moved away from the framevto permit the disengagement of the end of the bar 1 therefrom. lt is further to be noted that by merely unscrewing the screw 9 and the pin 13 the bars and co-operating levers can be entirely removed from the frame. lBy thisv simple means it is, therefore, apparent that they can be readily attached to any standard frame.

What we claim is 1. The combination with a pair of wringer rolls of a bar extending across, adjacent and above the line of contact therebetween, a pivoted plate connected to one end of said bar, ar motor controlling switch having a dependent stem, and a link connecting the upper end of said plate with said stem, the inward movement of the bar causing the outward movement of the upper end of the plate and the upward movement of the link on the switch stem, to open said switch.

2. The combination'witha pair of wringer rolls mounted on the frame of a wringer, of a bar disposed adjacent and above the line of contact between the rolls, one end of said bar bent up and acting as a pivot, a plate disposed against the frame of the wringer having a slot extending outwardly, in which slot the end of said bar is disposed, and a pivoted latch plate having a slot therein opening inwardly, said latch plate adapted to be swung up whereby the slot therein will engage with the end of the bar to hold it in the slot in the previously mentioned plate.

. 3. The combination with a pair of wringer rolls mounted ony the frame of a wringer, of a bar disposed adjacent and above the line of contact between the rolls, one end of said vbar bent up and acting as a pivot, a plate disposed against the frame of the wringer having a slot extending outwardly, in which slot the end of said bar is disposed, a pivoted latch plate having a slot therein opening inwardly, said latch plate adapted to be swungup whereby the slot'therein will engage with the end of the bar to hold it inthe slot in the previously mentioned plate, a plate pivoted to the other side of the wringer frame, the other end of the bar being attached to said plate below the pivot point thereof, a switch having a dependent stem, and a link connecting the upper end of said plate with said stem whereby the movement of the bar inwardly around its pivot point will actuate the link and the stem to open the switch.
