SAFETY ATTACHMENT FOB. WRINGERS.

Specification of Letters Patent. Patented AFLZU, 1915,;

Application filed March 8, 1913. Serial No. 752,809.

provide a wringer construction so arranged.

that in case of emergency, as for instance .u'hen clothing becomes entangled in the rolls or the operators hand is caught between the rolls, a safety device may be tripped to un-' lock the upper cross bar of the wringer, thereby releasing the spring pressure and allowing the rolls to separate freely.

While the invention is of. general utility in the artof ,wringing clothes, it is particularly advantageous when the vringer is power driven, as from an electric motor or gas engine.

The details of my invention will be made clear from the'following description which is to be taken in conjunction with the ac-' companying drawings, wherein- Figure 1 is a front elevation of one embodiment of my invention. Fig. 2 is a plan view of the same. Fig. 3 is an end elevation, indicating in dotted lines the position assumed by the cross bar of the wringer after it has been released. Fig.- 4: is a modified form having a somewhat diiferent release mechanism. Fig. 5 is a plan View of the same, and Fig. 6 isan end elevation.

In the construction shown in Fig. 1 the device embodies'a pair of wringer rolls 1 and 2 held in suitable bearings 3 of usual construction the upper ones being slidingly mounted in the usual way in standards 4 and Standards 1 and 5 are reinforced respectively near their top ends by metal braces 6 and 7 and the rear section of each is shorter than the front section and carries a bracket 8 serving to support a rod 9 which extends the entire length of the wringer and acts as a pivotal support for the arms 10 and 11. These arms 10 and 11 are bent to lie against the rear side of the wooden cross bar 12 of the wringeirand also overlap the top to form part of the latching mechanism whereby the cross-bar 12 is held in normal position.

The latching mechanism comprises a handle 13 pivotally supported at 14 to standard 5 and connected through a link 15 to a swinging latch 16 pivoted at 17 and having a hook at 18 engaging. with the projecting end of arm 10, thereby holding that arm against upward movement about shaft 9 as a center. Handle 13 is also provided with a hook 19 which latches over arm 11 thereby holding that arm against upward movement so long as handle 151s in its upright or nor and position.

liowever, when handle 13 is tilted over into the position shown in dotted lines, Fig. 1, the arms 10 and 11- are released and the top wooden cross bar 12- of the wringer canswing back about pivot 9 into the position in icated in dotted lines, Fig. 3. The aigm 10' may extend forward beyond the hook and may be shaped into a handle 10' for more ready return of cross bar 12 to its nor-;

mal position.

When the wringer in use in the normal manner and the rollers 1 and 2 are being rotated, as for instance by means of shell: or gear drive connected with one of the roller shaftsfthe thumb screws 20 will be-turned down in the usual way, compressing springs 21 to give the desired compression atthe rolls. Handle 13 in its upright position will hold arm 11 against upward movement and through the action of link-15 and latch 16 will also hold arm 10 against upward movement. If, however, the clothes should become packed between the rolls or tangled about one of them, or if the operators hand should be caught and drawn into the The modification illustrated in Figs. 4:, 5

and 6 differs in the details of the unlatch ing mechanism. In this case the end standards 22 and 23liave both their front and rear portions cut off to the same height. Each rear portion at its upper end is proprojectedend being slotted at 27 (Fig. ing-a cross bar, andadjusting means carthrough the upper ends of brackets 28 will indi cated in Fig. 4, thereby releasing the a separate. 7

Each 'Iplate 28' has a hole near its top end to receive a locking rod 29 mounted to slide in a bracket 30 andfactuated by a handle 31 pivoted at '32 and pivotally connected with the. locking rod at 33. The main crossbar 34 ofthewringe'r, is

mounted on the arms -26 of the hinges'and carries the. usual thumb'screyvs35 for adjusting the tensionof 'thesprings 36 'whereby pressure is applied to articles be' held the arms 26 in horizontal position, thereby holding the crossbar 34- against displacement and holding the adjusting Screws 35 to' their work against springs 36. But in'case ofem'ergency, the operator may swing'the handle 31 into the dotted position cross bar 34 and allowing itto swing over backward into the dotted position, Fig. 6,

and thus releasing the tension on springs 36 and allowing the rolls .of the wringer to.

Various changes in details may be made without departing fromthe spirit ofmy in-.- .vention as defined by the appended" claims.-
