Specification of Letters Patent.

Application filed February 7, 1920. Serial No. 357,051.

T 0 all Lo/om t may concern:

Be it known that I, IVILLIAM II. Mnrnn, a citizen of the United States of America, a resident of the city of St. Louis, in the State of Missouri, have invente-d certain new and useful Improvements in Clothes Vilringers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in clothes wringers, one of the objects being to provide a strong and simple wringer structure. Another object is to produce a simple releasing device whereby the pros* sure at the wringer rolls may be easily and quickly released.

Fig. I is a front elevation illustrating' a wringer embodying the features of this in vention.

Fig. II is a vertical section on the line II-II, Fig. I.

Fig. III is a section on the line III-III, Fig. I.

Fig. IV is a perspective view of a pres- Sure bar member, showing a releasing lever mounted thereon.

Fig. V is a perspective view of one of the bar sections constituting a latch device for locking the pressure bar to the wringer frame.

To illustrate the invention I have shown a wringer frame comprising upright sido members l forming housings for the bearings 2 in' which the wringer rolls 3 and 3 are rotatably mounted. The wringer frame also includes horizontally disposed upper members t integrally connected to the members l, said upper members being provided with longitudinal recesses 5. 4: designates caps secured tO the end portions of the upper members 4.

Compression springs 6 are interposed between the upper bearings 2 and a tie bar 3. Screws 7, acting upon the end portions of the tie bar 3', may be adjusted to vary the pressure of the springs 6. These springs allow the upper roll 3 to move toward and away from the lower roll, and they tend to force the upper roll into engagement with the lower roll. The screws 7 extend through comparatively large openings 8 in the caps et', but they are not secured in the caps, the Openings 8 being large enough to permit the screws to move vertically.

I To illustrate the preferred form of the invention, I have shown a. sectional pressure bar adapted to be broken longitudinally to release the springs 6, thereby allowing the upper wringer roll 3 to freely move away from the lower roll. This sectional bar comprises a main bar member A, which may be channel-shaped in cross section, and side bar members B between which the bar A is interposed. rTongues 9, extending from` theend portions of the bar members B, extend through Openings in the bar member A so as to pivotally interlock the bar members. The lower margins l0 of the bar members B extend into the recesses 5 so as to interlock the sectional pressure bar with the wringer frame. An operating handle ll, pivoted at l2 to the bar member A, is provided with a forked end which straddles the bar members A and B to retain said bar members in the positions shown in Figs. II and III.

Each end of the main bar member A is provided with nuts 13, which are threaded to receive the screws 7. It will therefore be understood that the pressure exerted by the springs is transmitted through the screws 7, and thence to the main bar mem ber A, and that this pressure tends to move the sectional bar vertically. However, when the sectional bar is inter-locked with the wringer frame, as shown in Figs. II and III, it cannot be forced upwardly by the spring pressure. To release the pressure, it is only necessary to strike the forked lever 1l so as to release its forked ends from the bar members B, thereby permitting said members B to swingen the pivots formed by their tongues 9, so as to release their lower margins l0 from the recesses 5 in the wringer frame. The springs 6 will thenforce the sectional pressure bar upwardly until the ends of bar member A strike the caps 4. The sectional pressure bar is thus broken longitudinally and unlocked from the frame so as to relieve the spring pres sure.

The sectional pressure bar is confined between the top members 4 of the wringer frame, as shown in Figs. II and III, so that the bar members B are not released from the bar member A when the sectional bar is thrown upwardly, and this sectional bar can be easily restored by forcing it downwardly until its lower margins engage the bottoni llO Walls of recesses 5 and slide into said recesses. After the bar has been restored it can be locked by restoring the operating lever 1l.

I claim:

l. In a Wringer, a frame, a pair of rolls, yielding means for forcing one ef said rolls toward the other, a sectional pressure bar whereby said yielding means isheld under pressure, said sectional pressure bar including sections pivotally secured together, the pivot being lengthwise of the sectional pressure bar, and said sectional bar being breakable longitudinally at the pivot in response tothe pressure of said yielding means, and an emergency releasing device cooperating With said pressure bar to prevent longitudinal breakage thereof.

2. In a Wringer, a frame, a pair of pressure rolls, yielding means for forcing one ofl said rolls toward the other, a sectional pressure bar interlocked with said frame to retain said yielding means under pressure, said sectional pressure bar including vertically movable sections pivotally secured te each other, the pivot being length- Wise of the bar, and said bar being breakable longitudinally at the pivot to unlock the sectional bar from said frame, and an emergency release preventing breakage of said sectional pressure bar.

3. In a Wringer, a frame, a pair of pressure rolls, yielding means for forcing one of said rolls toward the other, a longitudinally breakable sectional pressure bar comprising latch sections interlocked with said frame and a bar section through which thc pressure of said yielding means is transmitted to said latchrsections, said bar sec? tion being pivotally secured to said latch sections, and an emergency release device comprising a lever straddling said bar section and latch sections to prevent longitudinal breakage of said sectional pressure bar.

upon said latch members to prevent their displacement. f

5. In a Wringer, a frame, pressure rolls, yielding means for forcing one of said pressure rolls toward the other, a pressure bar to retain the yielding means under pressure, latch members pivoted to said pressure bar and interlocked With said frame, said pressure bar being interposed between said latch members, and an emergency releasing device comprising a lever pivotally mounted on said pressure bar and Vprovided With a forked end embracing said latch members to prevent displacement of said pressure bar.

6. In a Wringer, a frame, pressure rolls, yielding means for forcing one of said pressure rolls toward the other, a pressure bar to retain the yielding means under pressure, latch members comprising bar sections arranged longitudinally of said pressure bar and pivotally interlocked With the ends thereof, said frame being recessed to receive said latch members and the latter being extended into the recessed portions of the frame to prevent displacement of said pressure bar, and an emergency releasing device pivotally mounted on said pressure bar and straddling said pressure bar and latch members to prevent displacement of the latch members.

In testimony that I claim the foregoing I hereunto affix my signature.
