UNITED STATES FLOYD L CHAMBERLAIN, OF WATERLOO, IOWA.

wainonn-ramn CONSTRUCTION.

Application filed March 21, 1827. Serial No. 177,053.

My invention relates to improvements in wringer frame construction, and the object of myimprovement is to supply a rigid metallic frame for a wringer, composed o rigidly connected sections, whereby an inexpensive, simple .and strong structure is secured.

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. 1 is a side elevation of a wringer embodying my improved rigid frame construction, with the frame sections in vertical medial longitudinal section taken on the line 1--1 of Fig. 2, and with other parts broken away, or removed. Fig. 2 is a vertical transverse section of the device of said Fig. 1,-taken on the broken line 2-2 of said Fig. 1 looking in the direction indicated by the arrow, and Fig. 3 is a'horizontal section ofthe frame sections of the wringer taken on the broken line 3-3 of said Fig. 1, looking downwardly.

It is very desirable in the manufacture of metallic frame wringers, to make the supporting frame for the moving elements rigid but light, and so rigidly connected as to support said elements under severe stresses of use without giving at the joints or connections, while assuring economy in the construction because of the employment of light shapes and improved means for securing them together angularly. I

This is accomplished by my improved structure, in which light but rigid channel bars or shapes are used and angularly connected, and in which steel or other suitable metal is used.

The main frame comprises spaced vertical end standards 1 of like shape but reversed in position, and cut from channel steel opening inwardly toward each other with parallel side flanges 3 and having inturned angular and narrow flanges 2 on the side flanges 3, the flanges 2 being cut away a short distance above their lower ends, as shown in Fig. 2.

The numeral 5 denotes a channel bar section with side flanges 4 and opening downwardly, whose opposite ends are inserted in the lower end parts of the standards 1 and united rigidly thereto.

As shown in Fig. 1, the base section 5 has at each end its top part or web separated by cutting along the angles longitudi- .upwardly then outwardly terminally,

nally a short distance, and this partially separated or tongue part 6 is longer than the projecting parts beneath of the side f flanges 4., the latter being shortened. The

tongue parts 6 are bent upwardly at right angles to the web of said section 5, then bent again at right angles outwardly to provide horizontal end ledges 7 to provide supports for the lower roller-shaft bearings. The ends of the section 5 are fittedbetween the end standard flanges where the edge flanges 2 of the latter are excised, and secured thereto rigidly.

In the metal frame wringer of said Fig. 1, the moving parts are assembled similarly to those of other wringers, but the end ledges 7 of the base member 5 are employed as supports for the wooden bearing blocks 8 whose longitudinally grooved seats 9 receive the shaft pintles of the lower roller 10, the blocks 8 in turn serving as under supports for the superposed bearing blocks ll whose longitudinal bearing apertures 12 receive the end pintles of the upper roller 13. Laterally swinging top closure halves 15 are end-hinged to the upper parts of the standards 1 to swing to and from each other and be detachably fastened together by any approved coacting clamping devices, the compression spring 14 whose ends bear upon the blocks 11 being under the end compression medially of a set-screw mounted in a bearing in one of the top closure parts 15.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In 7 a wringer frame construction, spaced channel-bar standards with facing openings, and a downwardly opening channel-bar base connection therefor and rigidly connected thereto having its ends split longitudinally to provide web parts ben sa1 web parts and the separated portions of the flanges of the base connection being inserted into the openings of said standards, the horizontal terminations of the base connection serving as supports for bearin s positioned within the hollows of the stan ards.

2. In a wringer frame construction, spaced channel-bar standards with facing openings, and a downwardly opening channel-bar base connection therefor having its ends split longitudinally toprovide ,web 5' v :parts bent to have offset parts which serve as supports for bearings positioned within the hollows of the standards, the said web parts and the flange parts separated par- 5 tiallytherefrom belng attached to adjacent parts of the standards after insertion of these parts into the hollows of the standards to provide a rigid 'U-shaped frame structure to carry the moving parts of the wringer. 10

In testimony whereof I aflix my signal.-v ture.

FLOYD L. CHAMBERLAIN.
