PADDLE FOR WASHING MAGHINES.-

Original application filed. August 2, 1923, Serial No. 655,241. Divided and. this application filed March 28,

This invention relates to paddles or dashers for Washing, machinesof the type of that illustrated. and described in the pending application of George S. Blakeslee, filed March 29, 1920, Serial No. 369,741, which has matured into Patent No. 1,591,506, the present application being divisional of our copending application Serial No. 655,241, filed August 2, 1923, in which co-pending application there is also shown a washing machine of this general type. This invention has for its object to provide an improved paddle for use in such machines, which will enter the water smoothly and with least resistance, so.

and hereinafter described. What we regard as new is set forth in the claims.

In the drawings, I

Fig. 1 is a vertical sectional View of the improved paddle taken on line 11 of Fig. 2, illustrating particularly the means for securing said paddle on its supporting shaft;

Fig. 2 is a front view of said paddle, a portion of the supporting shaft therefor being shown in elevation;

Fig. 3 is a detail, being a section on line 33 of Fig. 1, the supporting shaft being omitted; and

Fig. 4 is also a detail, being a section on line 4-4 of Fig. 1.

Referring to the drawings,-5 indicatesprises two side plates 6, 7 each sectoral in illustrated this curved bottom plate 12 is Serial No. 19,020.

welded to the side plates so as to make a watertight connection therewith, as shown at 13 in Fig. 4, but it is to be understood that any other suitable means may be employed for securing the'side plates to said curved plate. As will be seen, the side plates 6 and 7 are somewhat triangular in shape, the upper margins 8 thereof'providing comparatively sharp leading edges which enter the water easily and without disturbance, as is desirable not only because the paddle wheel may consequently be rotated at high speed with less expenditure of power, but also because inwashing machines of the type with which our improved paddle is particularly adapted to be used, only a small quantityof water is usually contained in the tank and, as a number of paddles are generally provided, ar-

ranged to dip successively into the water, it is important that each paddle'operate in such manner as not to interfere with the efficiency of the others. By providing the extended side plates, also, the paddle takes up a considerable amount of water, and distributes it efficiently throughout the washing compartment. The extended side plates also function to laterally confine a body of watertherebetween in advance of the bottom wall 12 striking such body of water, and thereby prevent or minimize side splash of the water.

Such side splash is usually of little benefit for washing the articles in the machine, as it is onlythe water which is thrown radially by the paddle that has the proper direction and sufficient velocity to perform the cleansing operation.

To provide means for securing the paddle on its supporting shaft the end of the curved bottom plate 12 adjacent to the margins 8 of the side plates is turned back upon itself to form a loop 14 which clamps the shaft5, and an overlapping end portion or lip 15 thereof, which is bent to conform to the curvature of the main body portion of the plate 12, and i is secured to the main body portion by bolts 16 which pass therethrough, and nuts 17 screwed on said bolts. Thus the loop 14 may be clamped tightly down upon the shaft 5, thereby securing the paddle firmly in position on said shaft with the inner end of the bottom plate 12 in tangential relation thereto. It will be understood, of course, that the side plates 6, 7 are provided with suitable holes therein for the passage of the supporting shaft therethrough.

To guard against the paddle becoming loose on'said supporting shaft 5 because of the nuts 17 working loose, further securing means is provided comprising an'internally threaded collar 18, which is securely connected to the loop 14 by welding, or in any other suitable manner, and a set screw 19 which passes through said collar and is adapted to engage with the shaft 5, as shown in Fig. 1. It is obvious, of course, that the paddle may readily be removed, or adjusted on the shaft as desired, by loosening the nuts 17 and the setvscrew 19.

By constructing the paddle in the manner described, a plurality of such paddles may be mounted upon a supporting shaft at any desired distance'apart, and inany deslred angular relation to each other, and will enter the water-smoothly and easily without much resistance or disturbanceof the water, so that all the paddles will operate efficiently, and the paddle wheel as a whole may be economically operated at high speed. Owing to the wide side plates 6 and 7 the paddles will take up a considerable quantity of water, and by centrifugalforce will distribute it generally throughout theoupper portion of thewashing compartment, so that the interior of such compartment will be filled with flying particles of water which will thoroughly wash and scour-the dishes or other articles therein.

What we claim as the invention of said GEORGE S. BLAKESLEE, deceased, and Gnonen P. ANs'rIss, and desire to secure by Letters Patent, is p V 1. A paddle fCI-W2t-Sh-1-Hg machines comprising approximately triangular plates spaced apart and having a straight edge 8' and a long curved edge 10 subtending sub stan-ti-all'y a righ-tangl'e, and a curved bottom plate connecting said first mentioned plates together near the other edge thereof.

2, A- washing machine paddle constructed of two spaced side plates and a curved bottom' plate extending tlierebetwe'en, each of said side plates being of sectoral form and having its leading and trailing edges ex'tending substantially at right angles to each other, the lateral edges of said bottom plate being welded to said side plates adjacent to their trailing edges, a loop formed-in the inner end of said bottom plate to form a hub for -1nounting the paddle on a shaft, saidside plates having holes therein in alinement with said loop iorreceiving said shaft, and means for clamping said loop on the shaft,

3. A washing machine paddle constructed of three sheet metal stampings consisting oi? two spaced side plates and a-curved bottom plate extending therebetween, each of said sideplates being of sectoral form'and having its leading and trailing edges extending substantially at right angles to eachother, the lateral edges of said bottom platebeing secured to said-side plates adjacent to their trailing edges, and a loop formed in theinner' end of said bottom plate to pro vi'dea hub for mounting the paddle on a shaft.-

4. A washing machine paddle comprising two spaced side walls and a curved bottomwall, each of said side walls being of sec enonen P. AN s'Trss;
