March 18, 1930.. F, L, CHAMBERLAIN LZSQSS WRINGER Filed Nov. 9, 1928 Patented Mar. 18, 1930 'UNITED STATES FLOYD L. `GHAMBERLAIN, F WATERLOO, IOWA, ASSIGNOR TO CHAMBERLAIN CORPORATION, OF WA'lERllIOO, IOWA WRINGER Application led November 9, 1928. Serial No.318,225.

My invention relates to improvements in wringers, and the object of my improvement is to simplify the construction of a clothes wringer, strengthen and cheapen its construction, and lotherwise improve the assemblage of its parts, by shaping its 'frame rigid'- ly as a unitarystructure from metal stamped or formed to produce in one element a base, side bearing-standards, and front and rear drainage members, with other features of construction auxiliary to the purposes of the wringer.

This object I. have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig. l is a front elevation of my improved wringer. Fig. 2 is a Itop plan of the unitary frame parts of the Wringer, with other part-s removed,

but showing the lower roll and its bearing blocks emplaced. Fig. 3 is a side elevation of that side standard of the wringer frame which is apertured to pass the projecting end of a roller shaft. Fig. 4 is a medial cross sec- .25 tion of said wringer frame alone taken on the broken line 4 4 of said Fig. 2.

Minor modifications of the unitary frame structure of this invention are covered by and are within the scope of the. appended claims.

The frame structure and the hinged closure member 15 of this wringer are constructed of metal.

The improved frame comprises an upwardly troughed basal part l having a medial depending hollow vent tube 2. This base 'and the other connected parts of the frame, such as the side hollowr standards 4 and 5 and the front and rear drainage members 3 are preferably shaped by die-stamping or other appropriate means from a single plate of metal. When so stamped, successiviJ applications of dies are used to shape the different parts of said frame and produce the finished structure, but these will not be described, being known to and understood by those who are skilled in the art, but the unitary structure may be made by other means, and united from a plurality of different elements.

The basal part 1 has walls 3 projecting to front and rear of the standards 4 and 5 obliquely outwardly a considerable distance to perform the function of drainage boards. The side Walls of these drainage members at 6 are returns to the side standards set oli' inwardly from the side Walls of the standards which lat-ter close the sides of the basal trough 1.

Upper and lower pairs of spaced and apertured ears 11 are punched from the outer side wall of the standard 5 to receive fastening bolts to secure the wringer to any suitable bracketing means, such as a gear-case, mounted upon a washing machine or other appliance. Ears 22 are partially punched outQalso at 21 from both standards 4 and 5 and bent inwardly in the same horizontal plane to serve as supportingbrackets for the lower sets of bearing-blocksS mounted removably in the hollows of the standards to receive in longitudinal bearinghollows the end parts of the axial shafts, such as 9, of the superposed pair of' coacting elastic rubber rolls 10 and 14.` The standards 4 and. 5 are shaped with split inner walls which furnish clearance openings vertically to pass the shaft ends therethrough, and medially apertured inwardly flanged shield-plates 7 are mounted on the inner margins of these standards and have medial openingsto also pass the shaft ends therethrough. The outer wall of the standard 5 only has an aperture 13 to pass therethrough the more elongated shaft end 9.

The numeral 15 denotes a pair of like but reversed closure members having at their ends depending apertured tongues mounted hingedly upon outwardly projecting *fixed pins 16 on said standards. These closures are hollowed inwardly and downwardly to receive the usual bar spring (not shown) whose ends bear compressively upon the tops of the upper bearing blocks 8, the' spring being tensioned by the usual screw 17.

It will be seen, that the frame structure, including the basal trough, standards, and drainage members- 3,'are integral, and with their other features 22, 6 and '11, are made Ihn Y- i Y. 1,750,835

unitarily, by stamping or otherwise, at la great saving in expense, with maximum strength.v Having described my invention, what I claim as new, and desire to secure by Letters Patent, is: v 1. nfa wringer, a U-shaped unitary sheet metal frame structure, consisting of like longitudinally united halves, thev structure 10 including inwardlyV troughed erect standards,- and a basal connecting member therefor, being an upwardly troughed part with upwardly divergent walls wider at the top than said standards, the lower parts of said 5 standards having pressed in tongues to support apertured bearings for roller termina- Y tions, and an end wall of one standard having any aperture to be traversed by one of the roller terminations, said basal member- 2o having a drainage outlet.

2. In a wringer,- a U-shaped unitary sheet metal frame structure, consisting of like longitudinally united halves, the structure including inwardly trou hed standards, and abasal connecting mem er therefor, being an upwardly troughed part with upwardly divergent walls, the lower partsof the standards having inwardly projecting brackets to support roller-shaft terminations, one standard having outwardly projecting apertured Aears for connections to supporting means, and said basal member having a drainage outlet.

In testimony whereof I aix my signature.. FLOYD L. CHAMBERLAIN.
