FLUID-DISCHARGING- DEVICE.

Application led October 19, 1921.

To all whom` 'it lmay concern Be it known that we, HARRY IV. THOM- SON and IVILLIAM F. IVINKELMANN, citizens of the United States1 and residents of Jefferson City, in the county of Cole and State of Missouri.` have invented a new and useful Improvement in Fluid-Discliarging ,}r De-V vices, of which the following is a specification.

This invention relates to fluid discharging devices particularly adapted for washing dishes and is an improvement on the general type of dish washing device shown in Carter Patent, No. 1,328,942, patented Jan. 27. 1920, wherein a soap container, comprising a foraminous cylindrical shell having an imperforate bottom and a perforated cover having radial vanes thereon, is rotatably supported within a casing adapted to receive water from a faucet and discharge it as a soapy mixture.

One of the principal objects of the present invention is to provide for a more direct passage of the Water through the soap container, whereby a more soapy `mixture is produced. Another object is to protect the hands of the operator from the heat of the water passing through the device. `Another object is to provide a removable self-centering pivot-support for the soap container. Another object is to provide for the ready attachment of the flexible connection tube to faucets of different sizes and s apes. Another object is to secure a water-tight lock-joint between the cap andnozzle members of the device. Other objects are simplicity of construction, reduced cost of,

manufacture and increased efficiency.

The invention consists in an improved soap container, in the improved pivot-support for said container, in means for insulating the handle portion of the device, in means for attaching the fiexible connecting tube to various existing types of faucets,

I in means for securing a water-tight joint between the nozzle and cap members of said device; and it further consists in combinations and arrangements of parts hereinafter described and claimed.

In the accompanying' drawing which forms part of this specification, and wherein like symbols refer to like parts wherever they occur, e

Serial No. 508,700.

Fig. 1 is a side elevation of our improved dish-washingr device provided with means for detachably securing the connecting tube to an ordinary house faucet;

Fig. 2 is an enlarged central longitudinal section through said device on the line 2-2 in Fig. 1; l

Fig. 3 is a plan View of the nozzle member of the casing, showing the soap container mounted therein;

Fig. 4 is a similar view of said member, the soap container being removed to disclose the pivot-support therefor;

Fig. 5 is a side elevation of the soap container;

Fig. 6 is a perspective view of the pivotsupport therefor; and

Figs. 7, 8 and 9 are an end view, a longitudinal section and a side elevation, respectively` of the inlet end of the flexible connecting tube, illustrating in detail the` means for securing said end to the faucet.

In the accompanying drawing, our dishwasher is shown in the form of 'a tubular casing A comprising a nozzle member 10 and a cap member 11 having an enlarged portion 11 adapted to fit over the open end of said nozzle member. The enlarged base portion 11a ot the cap member 11 forms an annular shoulder 11h that overhangs the upper end of the nozzle member 10; and disposed between said shoulder and said end is an annular gasket member 11, preferably of india-rubber or other elastic substance. The nozzle member and carp member are preferably locked together against accidental separation by means of oppositely disposed bayonet-joints comprising cooperating projections 12- and Lshaped grooves 13 formed on the contacting portions of said nozzle member and said cap, respectively, the transversely extendin portions of the grooves being inclin u wardly. By this arrangement, the nozz e member can be readily secured to the cap b v a simple pushing and turning movement of the rejections 12 in the grooves 13, the inclined) portions of said grooves causing the u per edge of the nozzle member to be forced against the elastic gasket, thereby preventing leakage between the cap and nozzle members of the casing.

Extending upwardly Afrom the cap member 11 is an axially projecting inlet tube 14 adapted to fit into one end of a flexible tube 15, which is preferably held thereon by ceinenting. The opposite end of the tube 15 is adapted to be attached to an ordinary house faucet 16 in a manner hereinafter described. ber has a tapered nose portion 17 which is provided at its end with a plurality of discharge ports or spray orifices 18 after the manner of a rose-head.

Located within the lower portion of the nozzle member is a supporting member B comprising a wedge shaped plate 19, which is arranged with its apex down to fit the tapering nose portion of said nozzle member and has a rectangularly shaped integral cross-head 20 spaced above the upper edge or base of the triangle, said cross-head being twisted to a position at right angles to said triangular plate portion. The crosshead 2O and the base line of the trinangular plate 19 are of a length corresponding to the inside diameter of the upper portion of the nozzle member 10, thus preventing bodily movement of the supporting member in directions transverse to the axis of the casing. The cross-head 20 is provided, at its upper edge, with a bearing portion in the form of a semi-circular projection 21 located midway between the ends thereof and in line with the longitudinal axis of the casing.

Rotatably supported within the upper portion of the nozzle member 10 on the bearing portion 21 of the supporting' member 13 is a foraminous soap container comprising a perforated cylindrical shell 22 having an imperforate bottom provided with a central depression 23 adapted to fit the bearing portion 21 of said supporting member. The container is provided with a cone-shaped container. The apex of' the cone-shaped cap or cover 24 having a cylindrical base flange which fits over the upper edge of the cover 24 is disposed opposite to the inlet in the easing; and said cap is provided with a plurality of elongated slots 25 disposed transversely to the axis of the container and at right angles to each other. The metal resultingr from the punching of these slots is bent upwardly along the outside margin thereof in the form of opstanding flanges 24. lVith this arrangement, water upon entering the casing strikes the flanges 261 which constitute vanes, and the impact of the water thereon causes the soap container C to rotate upon the pivot-bearing 21 provided therefor on the supporting member B. The water upon striking the cover 24 for the soap container also passes through the openings 25 into the soap container. causing the soap therein to be commingled with the water passing therethrough. The resulting soapy mixture thence passes through the perforations in the wall of the container The lower end of the nozzle mem into the nose portion of the Casin and is discharged through the spray orifices 18 thereof onto the articles to be washed.

The flexible tube 15 is provided at its inlet end with a thiiublc 2T for readily attaching said end of' said pipe to faucets of various types. Said thimble comprises a cylindrical sleeve provided at one end with an annular Harige 2S. The thimble is sleeved on the flexible tube 15 and has a flared portion 29 which forms a conical seat or shoulder adapted to bear against a bead il() formed on the inlet end of said tube. One end of a chain 31 is secured to the annular flange 28 of the thimble 2T, and the other free end portion of said chain is adapted to be inserted laterally into a notch 32 formed in the opposite side of said annular flange. The tube may be securely attached to the faucet 1G by forcing the inlet end of said tube over the end of' the faucet. The fre-e end of the chain is then looped around the valve portion of the faucet, then drawn tight, and then inserted sideways into the notch 82 in the thimble 27, lengthwise movement of' the chain through the slot being prevented by the enlarged return-bends of the links. The action of pulling the chain tightly about the faucet draws the thiiuble 27 against the beaded portion 30 of' the tube and prevents the tube from being forced ofi' the faucet blv the pressure of the water and enables a tight joint to be maintained between the faucet and the tube.

By reason of the` dish washer being a hand-held device, it is important that the hands be protected from the heat of the hot water passing therethrough. To protect the hands of the operator from such discomfort, the device is provided with a tubular handle in the forni of a tubo 33, which tube surrounds the flexible tube 15 adjacent to the inlet end of' the casing. The tubular handle 33 is of two diameters, the smaller diameter being cemented to the tube 15 at its point of connection with the inlet tube 14 ol' the cap 11, and the enlarged portion of the handle being spaced away from the tube 15. This arrangement leaves an air space between the handle and the tube that protects the operators hands from the heat of' the hot Water passing through said tube.

Obviously, the construction hereinbefore described admits of considerable variation Without departing from the invention.
