FOUNTAIN SPONGE Filed Oct. 22, 1940 2 Sheets-Sheet 2 Inventor M/b'am 15. Ha eck I By A tiorney Patented July 29, 1941 UNlTEjD STAT-E T 'FFl CQE '2 Claims.

The present invention relates to new and useful improvements in cleaning devices designed primarily for use in cleaning automobiles and other vehicles and has for its primary object to provide a sponge having perforations therein and connected to a suitable source of water supply under pressure whereby to produce a spray which is subjected to the body of the automobile for washing loose dirt and other substances therefrom while the sponge is being used for cleaning the same.

An important object of the present invention is to provide a novel connection for the hose to which the sponge is attached adapted to relieve the hose of excess pressure and also with a view of strengthening the hose at its point of connection with the hose coupling.

'A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference b ing had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a side elevational view of the hose and fountain sponge connected thereto,

Figure 2 is a fragmentary sectional view through the sponge,

Figure 3 is a transverse sectional view taken substantially on a line 33 of Figure 2,

Figure 4 is a sectional view through the hose illustrating one of the guard rings mounted thereon, and

Figure 5 is a longitudinal sectional view through the hose coupling.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates a sponge of predetermined configuration and having a chamber 6 formed therein within which is fitted a rigid plate member I, the plate having a beading 8 formed at its marginal edges to prevent cutting into the body of the sponge. A plurality of discharge passages 9 are formed in the sponge and extend from the chamber 6 outwardly through one wall thereof.

A rigid tube II] has one end disposed flatwise against the plate I in the chamber 6, the other end of the tube extending outwardly through an opening II formed in an end wall of the sponge and on which is frictionally fitted one end of a rubber hose I2. To the other end of the hose I2 is secured a pipe fitting designated generally at I3 which includes a rigid tubular member I4 having a flange I 5 formed on one end and having its other end frictionally fitted within the hose I2, the hose being secured in position on the member I4 by means of a hose clamp I6. A beading Il may also be formed on the inner end of the tubular member I4 to assist in retaining the hose in position thereon.

Engaged behind the fiange I5 is the conventional threaded hose coupling member I8 adapted to be threadedly engaged with the outlet of a water pipe or other supply line under pressure.

A portion of the tubular member I4 is of reduced diameter as shown at I9 todefine a, shoulder 20 against which the adjacent end of the hose I2 is adapted to abut. The reduced portion of the tubular member I4 is also formed with a plurality of perforations 2| which are normally covered by the end of the hose I 2 as shown to advantage in Figure 5 of the drawings.

A rubber bulbous shield 22 is provided with a neck portion 23 which is slidably fitted over the hose I 2 at a point between the clamp It and the coupling I8, the other end of the bulbous member 22 being formed with an enlarged opening 24 within which the coupling I 8 is inserted. The member 22 covers a portion of the tubular member I4 provided with the perforations 21, so that in case of excess pressure of water entering the hose I 2 the water will be forced through the perforations 2| so as to expand the hose I2 into the dotted line position as shown at 25 to permit the escape of water into the member 22 and out through the enlarged opening 24, the elasticity of the member 22 permitting such escape of the water.

. Also in order to enable the coupling IE to be attached in position to the supply line, the member 22 may be slidably moved inwardly of the hose I2 and then returned to its position as shown in Figure 5 of the drawings.

From the foregoing it will be apparent that the device is admirably adapted for use in cleanmg automobiles and other vehicles, the spray passages 9 being formed on one side of the sponge only in order that the spray may be properly directed on the work.

In order to protect the body of the car from injury by the rubber hose I2 I provide a plurality of sponge rings 26 which are secured in spaced relation on the hose adjacent the sponge 5.

It is believed the details of construction, ad-

vantages and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention, What I claim is- 1. A fountain cleaning device comprising a soft porous head having a chamber therein, a rigid plate in the chamber forming an imperforate back wall for the chamber, discharge passages extending from the chamber through a wall of the head and a rigid liquid supply pipe extending through a wall of the head and terminating in the chamber fiatwise of the plate to space the wall of the chamber having the discharge passages therein from the plate.

2. A cleaning device comprising a porous head, a rigid plate embedded in the head having a beading at its edges to space the plate from the material of the head to form a chamber therein, said plate forming an imperforate back wall for the chamber, discharge passages extending from the chamber through the wall of the head and a rigid liquid supply pipe having a discharge end extended into the chamber for supplying liquid thereto, said inner end of the pipe spacing the wall of the chamber having the discharge passages therein from the central portion of the plate.

WILLIAM E. HABECK.
