DISH-CLEANER.

` SPECIFICATION forming part of Letters Patent No. 686,450, dated November 12, 1901.

Application iiled May 4, 1901.

To all whom t may concern:

Be it known that I, DANIEL W. HAwKEs, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and use` ful Improvements in Dish-Cleaners and I d o hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in dish-cleaners, and more particularly to means for subjecting the dishes to a water spray.

' It is applicable to any device lwhich is capable of throwing a stream of water.

It also relates to certain details of construction and arrangement of the parts, which will be hereinafter more fully described and claimed.

In the drawings herewith accompanying and making a part of this application, Figure l is an isometric view of my improved dish-cleaner, and Fig. 2 is a central vertical sectional view of the same.

Same letters of reference refer to like parts.

In said drawings, A represents a tank or receptacle', in which is mounted a force-pump consisting of a pump-barrel B, plunger C, inlet-valve D, and a delivery-spout having a horizontal section E and a vertical section E', terminating near the top of the receptacle and adapted to throw a stream Vof water npwardly. Above the open end of the deliveryspout is a sprayer, which 'consists of an inverted hollow vessel F, the open end of said vessel being arranged directlyover the end of the delivery-spout, but spaced apart somewhat therefrom in a vertical direction. The opening in the inverted vessel should be of a diameter not greater than the column of water delivered from the spout. Said vessel may be supported above the delivery-spout in any convenientmanner and be within the scope of my invention. I have illustrated it as secured to a sleeve or collar G by means of rods H. The collar goes on over the end of the spout and may be provided with a pin I, adapted to enter a rectangular recess J in the collar, the collar and delivery-spout thus having whatis known asa bayonet connection. The inverted vessel may have the form of a truncated cone-base upward, the open end of Serial No. 58,832. (No model.)

the vessel being of less diameter than-the closed end. The open end of the vessel may be surrounded by an externally-projecting rim K, concentric with said open end, and

said rim may be inclined downwardly, if desired; but I do not intend hereby to limit myself to any particular formation or structure of said spreading vessel.

The bottom of the tank has a central recess or depression L therein adapted to contain the horizontal section E of the deliveryspout. This is arranged centrally, so that the vertical section of the delivery-spout can have a central position relative to the walls of the tank. In the side of the wall opposite the pump and at the bottom of said recess is an outlet-port O, through which the tank may be emptied. The pump may be secured to the tank in any convenient manner, as by brackets P.

The operation of my improved device is as follows: The inverted vessel being full of air, when the stream of water from the deliveryspout is projected into it the air is compressed by the force of the water and then expands and throws the water back in all directions, spreading it out to the sides of the tank and all intermediate points between the sides and the delivery-spout. The water only enters the mouth of the vessel, and the air distributes the water over the surface oi' the tank much more thoroughly and evenly than when it is done when the water is projected against a disk over the open end of the delivery-spout. The spreading of the water especially to the outside of the tank is facilitated by the external rim or iiange secured about the mouth of the hollow vessel. The dishes are placed upon the bottom of the tank above the depression therein either upon the bottom of the tank itself or upon a rack placed thereon, (the rack not being shown, it forming no part of my present invention.)

Having thus described my invention and its use, I claimha l. In a dish-cleaner, a tank, a pump mounted therein and having a delivery-spout and an inverted open vessel positioned above the end of the delivery-spout and spaced apart therefrom, the area of the open end of the vessel being not greater than the area of the solid column of water delivered by said spout.
