DISH WASHING APP RATUS Filed Jan. 29. 1929 2 Sheets-Sheet 2 Patented Nov. 10, 1931 UNITED STATES PATENT OFFIC CARL J'AJIIES PETERSEN, OF BROOKLYN, NEW YORK DISH WASHING APPARATUS Application filed January 29; 1929. Serial No. 385,783.

This invention relates to a dish washing apparatus which is designed for attachment to the faucet of a kitchen sink and which receives its operating power from theforce of.

water power driven rotary mop which ismounted for free gravitational engagement with the dishes so that the weight of the amp element and its component parts exert the proper wiping pressure on the dishes.

As a still further object, the invention aims to provide an improved mop which isradially contractible and expansible to adapt the same for use respectively with cups, glasses and similar small diameter table ware and with dishes, plates or other larger diameter table ware. r As a still further specific feature of the invention, a mop is provided which includes radially adjustable arms having depending strands with means extending below the arms for engagement with the dishes to prevent contact of the arms therewith while permitting the strands to have a wiping engagement with the surface.

. The invention further embodies an adjustable faucet attaching bracket, by virtue of which the device may be associated with fancets of various types.

Other features of the invention reside in the simplicity of construction and mode of use of the device, the economy with which it may-be constructed, the facility with which it may be attached and removed and thegeneral efiiciency derived therefrom.

With the above recited and other objects scription and accompanying drawings, in

which there is exhibited one example or. embodiment of the invention, while the claims define the actual scope of the same.

In the drawings- Figure 1 is a perspective view of the in view, reference is had to the following de 1 device in applied position to a faucet, and illustrating the mop radially expanded for operation upon plates or dishes of large diameter. i j

Figure 2 is a. transverse sectional view through the water motor.

Figure 3 is a detail sectional view illustratingthe attaching bracket, taken approximately on the line 33 of Figure 1.

c Figure 4 is a perspective view of the rotary mop in its contracted condition for washing I cups, glasses or similar small diameter table ware.

Figure 5 is a vertical transverse sectional view therethrough taken approximately on the line 5-5 of Figure 4.

Figure 6:is a detail horizontal sectional View taken approximately on the line 66 of Figure 5.

Referring to the drawings by characters of reference, the water motor includes a sub- I stantially cylindrical water wheel housing 10 which is provided with an upstanding tangential inlet nipple 11 which carries an elastlc connecting element 12 adapted to snugly fit the outlet end of the faucet A. Thenipple and connecting element are formed with an internal bushing 13 provided with a downwardly extending frusto-conical bore 14. Within the housing 10 a water wheel is arranged consisting of a hub 15 secured onto a transverse shaft 16, said hub being provided with radially projecting circumferentially spaced blades 17 adapted to receive the impactforce of the water discharged from the faucet A through the connecting element 12 and inlet nipple 11. It is, ofv course, understood that due to the frusto-conical bore 1d,

the velocity of the water discharged against the blade is increased, thereby increasing the force applied to the water wheel. The water c. wheel shaft 16,is journaled in the walls of the housing 10, and in the present instance said shaft is disposed horizontally with one end extending through the housing and having secured thereto an exteriorly disposed pinion 18. The housing, 10 carries an angular bracket arm 19at its rear side and the upper horizontal portion 20 of the bracket means for attaching the bracket arm to the faucet A so as to allow for adjustment, a U- shaped member 22 is employed, the terminals of the arms of which are embraced by a clip 23 which is provided with an upstanding threaded shank 24 which extends through the slot 21 and receives a thumb nut 25. A substantially S-shaped bolt '26has its-terminal 27 engaging the bight 28 of thou-shaped member 22 while the reversely bent remaining portion embraces thefaucetA"with thethreaded terminal 29 extending between the v legs of the U-shaped member 221 "A; clip 36 is arranged over the threadedterminal29.

and a thumb nut 31 is applied thereto for the purpose of setting'up thedesired clamping action. This suspends and supports the housing 10 from the faucet. The front wall of the housing from which the gear'18isexposed is provided with vertically. spaced bearing

arms

32 and 33 in which a tubular vertically disposed shaft 3 1 is'journaled for rotation. The shaft 3 1 has secured thereto a annular upper and

lower flanges

38 and 39,

between which a pair of semi-circular arms 40 are pivoted at 41 at diametrically opposite points for swinging movement from a position coincident with the periphery of the flanges, as illustrated in- Figure 4, to a radially projected position, as. illustrated in Figure 1. The arms are provided' with extensions 42 beyond their pivotal points 41 for a purpose to be hereafterset forth. In order to provide means for locking the arms either in their contracted or expanded relations, a detent element is provided which consists of a cross-head 43* which is centrally apertured to slide vertically on the upwardly projecting stem 44 of the mophead. A coiled expansion spring 45 surrounds the stem and is interposed between the crosshead and the enlarged upper end 46 of the stem 1 1. The cross-head is'providedwithdepending pins 47- which are designed toproject through aligned apertures 48 in: the

flanges

38 and 39. When the arms 40 are swung inwardly or contracted to a position to coincide with the peripheries of the flanges, the pins 47 are disposed inside of the extensions 42, as illustrated in Figures 5 and 6, but when the arms are swung outwardly the pins engage outside of the major portions of the arms, as illustrated in Figure 1 of the'drawings. In order to providemeans-for'facilitating the raising of the cross-head: against:

the action of the spring 45, manipulating lugs 50 are provided. The upper end of the stem 16 is provided with a socket 51 which receives the lower end of the mop shaft 36 and set screws 52 serve to retain the stem and socket in connected relation. The upper end of the mop shaft 36 is provided with a swiveled. head 53, and. below. the. head a weight5i is secured to said shaft so that the mopping element will tend to normally gravita'tedownwardly. The-mop arms 4:0 receive thereover. tubular bands 55 which support the mop strands 56 and the tubular bands 55 are held inzplace by means of hooks 57 which engage through openings 58 at the inner endsof-themop' arms. In order to prevent the mop head from. gravitating into, contact with the dishes B. while permitting the strands only to wipe over the surfaces of the dishes, a nipple 59 depends concentrically fromthe head, which. nipple is of considerably lesser. length than the length of the strands. 56. V

Inorder to provide means for. spraying the.=dishes with water from the faucet afterl the force. of the same has acted upon the water wheel, the maindischarge spout 60 at the lower end of: the. housing 10 which is directed: rearwardly,.is :formed at its closed forward end 61 with. a sprayer opening 625T This permits a portion-of the water to spray onto the dishes and mopwhile the major portion i ofv the discharged .water isdirected rearwardly' against the rear surface of the sink to prevent splashing. It is, of course, obvi-' ous thatwhencups, glasses or similar table ware of small diameter are being washed, the arms l0 willbe. swung inwardly, to the position illustrated in Figure at and the operator maygrasp theiswiveledknob or. head 53 at w the upper end for moving: the mop upwardly and downwardly.

What is claimed is: V v 1. In a dish washing apparatus, a rotar mop, means for mounting the same for free gravitational engagement: with the dishes, said mop having a head and. depending strands, andmeans oflesser length than the mop strands to. engage with the dishes for holding the head: in. superposed relation to" the upper surfaceof a dishwhile permitting saidmop strandsto trailover. the said surface and accommodate themselves to the varying configuration. of-v the dish being washed.
