CLOTHES- SPECIFICATION forming part of Letters Application iilefl August 29, 1896.

To au whom, it may con/cern.-

Be it known that I, GUsfrAvUs A. PADDocK, a citizen of the United.v States, residing at Beaver Dam, in the county of Dodge and State of Wisconsin, have invented certain new and useful Improvements in Clothes-Wringers; and I do hereby declare that the following is a full, clear, and eXact description of the same.

.My-invention has for its object to provide simple, economical, and easily operating clothes-wringers in which the rolls may have ready wide separation Without detriment to the driving mechanism and also to insure the proper pressure' at all times without disturbing the adjustment of the'regulating device.

Therefore said invention consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with subsequently claimed.

Figure l of the drawings represents a partlysectioned tub-side view of a clothes-wringer constructed in accordance with my invention, certain parts of the same being broken; Figs. 2, 3, 4, and 5, sectional views respectively indicated by lines 2 2, 3 3, 4 4, and 5 in the first figure; Fig. t5, a detail perspective view of a bell-crank lever embodied in the wringer and Fig. 7, a detail plan view, partly in horizontal section, illustrating the swing-clamp similar to one of those shown in preceding iigures applied to a notched-end frame-standard.

Referring by letter to the drawings, A indicates the top bar of the wringer-frame, A' a leg made fast to the lower notched portion of a longitudinally-slotted frame-standard A2, and A3 indicates the other longitudinallyslotted frame-standard of the machine. The top bar is bolted in the slots of the framestandards, at the upper ends of the same, and fast to said standards, near their lower ends, is a watershed N and backboard h, aA clothesboard s being trunnioned to the aforesaid standardsY above said watershed. The general construction and-arrangement of parts thus far specified are common in the art of clothes-wringers, hard-wood being the material employed in the manufacture of said parts.

Made fast to the leg A' of frame-standard A2 is a bracket o', that constitutes a bearing WRINGER.

Patent No. 628,545, dated July 11, 1899.

Serial No. l604,339. (No model.)

for a set-screw O, one end of which is swiveled in-a plate 0, havinga lower right-angled prong p, that moves in space between said leg and bracket to keep said plate in vertical position when said screw is adjusted. The parts in the last-described assemblage, with the exception of the wringer-frame, are made of metal and 'constitute one of the clamps by which the wringer is held on a tub or other support.

In pivotal connection with a bracket R, fast to frame-standard A3, is a yoke P, and a setscrew Q, having bearingin one end of the yoke, is `provided with a swivel-button designed to come against a tub or other support, the lastdescribed assemblage of parts being metallic and constituting the other clamp for holding the Wringer on a tub or other support. In Fig. 7 the frame-standard A3 is shown as having a notched lower end provided with a swingclamp comprising a bracket R, yoke P in pivotal connection with the bracket, and a setscrew Q', having its Abearing in one end of the yoke, said screw bein g provided with a swivelbutton, this clamp being similar to one of the others above speci'iied. lVhile l have shown the clamps as part of a complete clothes- Wringer, said clamps are similar to what is already common in the art, and therefore they are not specifically claimed herein.

The Vertical slots in the frame-standards are shaped at their lower ends to provide bearing-spaces m' for the shaft m of the lower wringer-roll M, and in sliding engagement with said slots are the bearing-frames H G for the shaft Z of the upper wringer-roll L, these bearing-frames being for the most part above the latter shaft. As herein shown, the bearing-frames that slide in the vertical slots of the f rame-standards may be cast metal and have hard-wood blocks h' g arranged therein for contact with shaft Zof the upper wringerroll. The block gis made to serve as a bearing for the drive-shaft J, herein shown provided with a crank k, and the other bearing for the drive-shaft -is herein shown as a notched blockj, made fast to the frame-standard A2. e

A sprocket-pinion I is made fast to one end of the drive-shaft, and the other end of said shaft is fast in a spur-pinion K. The sprocketpinion is connected by a link belt i with IOG spring C is connected, the other end of the,

spring being in connection with the eye end of a screw F, that extends through one arm of an angular casting b, hereinshown as having lateral trunnions that bear in recesses at the upper ends of side arms constituting part of the bearing-frame G. Another casting a has hook branches that bear on trunnions extending laterally from the upper inner corner of the bell-crank lever D, and the latter casting and the one b are shown connected to ends of a wooden bar B, that is approximately parallel to the wringer-rolls.

A tension-nut f is run on screw F between side bars of bearing-frame G to oppose the depending arm of casting Z7, and the wooden bar B is shown provided with a recessed metal block constituting a socket for the point end of a pressure-regulating screw E, for whicha bearing is provided in the top bar A of the machine.

The bell-crank lever D is provided with laty eral lugs in opposition to the hook branches of casting a to prevent pressure on the wringerrolls,eXcept the regulating device be adjusted, 1

these lugs being well illustrated in Fig. 6.

In practice rotary motion of the drive-shaft is communicated to the lower 'wringer-roll by the sprocket and link-belt gear above speci' fied. Like motion is also communicated from the drive-shaft to the upper wringer-roll by vmeans of the spur-gear set forth in the foregoing. When material is run between the rolls,

the upper one of the same is lifted against a l double amount of friction, as by the side pressure of the cogsagainst each other each of the shafts would be pressed sidewise against the bearing-box by the force used in propelling the rolls. At the same time none of the downward pressure on the lower roll-shaft is taken off, but rather added to, as the pressure of the cogs against each other will increase the friction on the lower side of said roll-shaft and make a corresponding amount on the upper side of the drive-shaft; but'in my gearing above set forth I overcome the mechanical defect heretofore experienced ,for, as'will readily be seen, all the pull of the link belt is downward on the drive-shaft and correspondingly upward on the shaft of the lower roll, thussimply transferring part of the rollpressure from the latter to the former. Therefore instead of having merely substituted one well-known form of gear `for another as a means of communicating rotary motion to the lower roll from 'a drive-shaft in spur gear with the upper roll-shaft I make provision to avoid increase of friction from the adding of another shaft to the wringer.

The degree of spring-pressure is regulated by adjustment of tension-nutf independent of the wringer-frame, and this pressure is brought upon the roller by adjustment of the regulating device, herein shown in the form of a set-screw operative upon bar B. The oscillating bell-crank lever D operates to automatically maintain an equal rollpressure whether -the material operated upon be .thick or thin, and this function will be best understood by observing that if lines drawn from the center of each lever-hook intercept each other at the axial center of the trunnions pertainingto said lever their intersection will form an acute angle.. Now if the bell-crank lever swings down and outward on its fulcrum incidental to spreading apart of the wringer-rolls the distance from the trunnions of said lever to the link c, in connection with IOO spring C, will decrease more rapidly than the p 1.
