Specification forming part of Letters Patent No. 35,705, dated June 24, 186'): reissue No. 5,330, dated March To all whom it may concern:
Be it known that- I, TIIODIAS'POOL, ofBruns- "wick, in the county of Medina and State of Ohio, have invented a new and useful Im-- provement in Clothes-\Vringers; and I do hereby declare that the following is a full [and exact description of what Iconsider the best means of carrying out the same, refer Figure 1 being a central longitudinal ver: tical section of the clothes-wringer; Fig. 2, a
p side elevation thereof.
Like letters designate corresponding parts in both figures.
My invention applies to clothes-wringers, 7 ilrwhich two pressure-rollers, generally made of India rubber, are mounted in a suitable framing; and relates to means for securing the proper elastic separation and closing of the rollers, and for guiding the bearin gs there- -I employ asimple wooden. frame,.com'posed of the upright pieces A A, cross-piece B at the top and another cross-piece, 0, toward the bottom, of suitable dimensions and of any convenient construction. The uprights or posts A A are suitably provided with notches a. a, or their equivalents, for attaching to a tub or other support. An inclined board, 1;), is.situated beneath thevposition otgthe rollers and over the lower cross-piecc U," all substantially as represented in the drawing. The rollers E F, of India rubber, or equivalent material,
are secured in the ordinary manner to shafts G H, one of which projects from the frame, "andis provided with a winch orvcrank for tnrnin g the rollers. The. journals of the shafts play vertically in slots 1) b in the side framepieces A A, both haviii g thus a'free movement up anddown, sufiicient to allow the rollers to separate as far as ever required. Instead of ailoIing-onlyone of these rollers to yield to madam the different .sineso'f articles to be wrung, louse both to .1 simultaneously, substantially as follows: i
I employ two sprin gs, M N, generally straight,
and as long as practicable, and in fact reachin g the whole width of the frame, and project iug a little at each end. One of them is located on the. top of the upper cross-piece B of the frame, and the other is secured to the under side of the lower cross-piece O, the exact location, however, not being essential. They are respectively attached to the crosspiece at the middle by screws 0 c, or their equivalents. These springs are of equal, or nearly equal, strength, and at both ends alike, so that the yielding will be equal at both ends, and downward as well as upward. They are aslong as practicable, so as to get as little variation of force in their movement as possible, and this 1 result is enhanced by the employment of the two springs, thereby getting a greater extent of spring-movement with the same. variation of elastic pressures The pressure is communicated from the springs to the journals of the roller-shafts G H by means of sliding bearings P l and Q Q arranged in a peculiar manner. They are held in place by a. vertical slot in. each, which plays respectively over a. screw, f, or its equivalent, passing through the same into the frame of the machine. One end of each bearing simply abut-s against the projecting end of one of the springs M N, which is generally bent over the same, as shown, and the other end of each bearing is hollowed atg, so as to fit against, and partly around, the shafts G H respectively. These concave surfaces thus not only furnish bearings for the roller-shafts, but, on the other hand, the shafts keep the bearings in place, preventing them from turning round out of position.
This construction of the machine is exceedingly simple in all its parts, tl1e wood parts being plane pieces, and the metal port-ions being either simple castings or of such planeand round forms as to be quickly and easily made and put together; jects aimed at, cheapness and simplicity of construction, durability,and efficiency of action, are gained. 1
, What I claim as my invention, and desire to secure by Letters Patent, is'
1. The combination of twov pressure-rollers with a slotted supporting-frame, in which the amrnoromrnn hence the great ob axes of both rollers are free to move toward and from each other, and with yielding bearings acted on by springs to allow the move n'n of both rollers, and thereby increase the elastic action, substantially as herein specified.
2. In connection Wlt-h the above, giving an equal, or nearly equal, elastic action toeaeh roller by means ofthe long springs M N, made exact counterparts of each other, and arranged substantiallyas and for the purposes herein set forth."
25. The (:omblnat ion and arrangement of the spring-orsprings M N, slid. l 1 P Q Q, having guide slots g g, and the stationary gui ff applied to the rollers, subsr for the purposes herein specified, In testimony whereof I have hereunto set my hand this 11th day of January, 1873.
