' 1 Claim.

My invention relates to cleaning devices, and more particularly relates to a fountain cleaning device for supplying a cleaning solution through an applicator to surfaces to be cleaned.

The primary object of my invention is to provide an easily portable fountain cleaner ofadequate cleaning fluid capacity having a convenient applicator.

Another object of my invention is to provide a simple, inexpensive and durable cleaning fluid reservoir of the pneumatic type, which is easily operated.

A further `object of my invention is to produce an applicator of simple and inexpensive design, and which is light in Weight and has a maximum eiciency.

Still another object of my invention is to provide a leak-proof applicator control valve of simple design.

With these and other objects in View, which will become apparent as the description proceeds, my invention is embodied in a portable cleaning fluid reservoir provided with an air pressure pump and adapted to supply an applicator ,with fluid under pressure via a connecting flexible tube, the applicator being shaped to fit the hand and having a finger-operated valve for release of the uid to the working surface.

The invention, both as to details of construction and combination of parts, will best be understood from the following description of a specic embodiment, which I illustrate as an example, when read in conjunction with the accompanying drawings, in which:

Fig. 1 is a view showing the fountain cleaner of my invention as worn and held by an operator.

Fig. 2 is a perspective View of the applicator of Fig. 1.

Fig. 3 is a longitudinal sectional View of the applicator of Fig. 2. l

Fig. 4 is a section on the line 4-4 of Fig. 3.

Fig. 5 is an elevational View, partly in section of the applicator control valve.

Fig. 6 is a perspective view of the reservoir in accordance with my invention.

Fig. 7 is a side elevational sectional view of the reservoir of Fig. 6.

Fig. 8 is a sectional view of the preferred embodiment of my applicator taken on the line 8-8 of Fig. 9.

Fig. 9 is an end View of the applicator.

Fig. 10 is an end view of the sponge and spring member.

Fig. 11 is a perspective View of one of the springs per se.

Referring now to the drawings, I show in Fig. 1 a reservoir A and an applicator B connected by a exible tube C for transferring cleaning fluid from the reservoir to the applicator. The reservoir A is attached to the wearer by means of straps lil and is equipped with a bulb type handoperated air pressure pump l2 for placing the contents under pressure.

As shown in Fig. 7, the pump I2 supplies air under pressure to the interior of the reservoir A, which is preferably of metal, by way of an internal metal tube I4 opening into the topmost part of the reservoir, illustrated as in the lling cap extension i6. Air is thereby compressed above the liquid contents (not illustrated) in the reservoir. The liquid cleaner leaves the reservoir by way of the metal withdrawal tube I8 which extends from the outside downwardly through the top of the reservoir and opens to the interior at the bottom of the reservoir A so that the entire contents of the reservoir can be expelled.

The flexible tube C, preferably of rubber, 'is attached at one end to the external end of the tube I8 and at the other end to a tubular extension 2U of the valve 22 of the applicator B. This valve comprises a hollow casing 24 having an inlet tubular extension 2li and an outlet tubular extension 26, each communicating with the interior, a slide valve 23 reciprocable within the casing 24, a valve stem 30 passing through the casing 24 at a tubular extension 32, and a manually controlled button 34 at the end of the stem 30. The button 34 is provided with an extension 36 in the direction of the stem 3U and of theA same external diameter as extension 32. A rubber tube 38 nts over extension 32 and is held in place partly by its elasticity and by a helical spring 40, which lits over the tube 38 and grips it tightly to the extensions 32 and 35. The spring 40 is under longitudinal compression so that it urges the slide 28 to the left or closed position, as shown in Fig. 5. Pressure to the right on button 34 forces slide 28 past the opening of inlet 20, thus opening the valve by placing openings 20 and 26 in communication. Any cleaning fluid which nds its way from the valve casing 24 past the stem`3 through the opening in extension 32 is held in the rubber tube 3l) and prevented from leaking outside the casing. A plug 42, threaded into casing 24 opposite extension 32, is provided rable material tted into the body 50; a metallic body locking `member 54 whose purpose is to secure the body 50 in place and to hold the valve 22; and a cover 5S which is made of Wood or other heat insulating substance, is shaped to t the hand and comprises the handle or grip of the applicator. The body 50 is formed with a flat-bottomed cavity on the upper surface with the sides of the cavity undercut horizontally in the plane of the cavity bottom, the cavity bottom including the undercut extensions being of a size to fit the member 52. When member 52 is fitted into said cavity, the overhanging sides of said cavity overlap said member. Threaded cylindrical spacers 58 are secured to member 52' by screws 60, pass through openings in the member 54, and secure the cover in place on the body 5I) and member 52 by means of'screws SZ. Member 54, to which the valve 22 is fixed, lies be.- tween member 52 and the cover 56 and has a turned-down edge. TheY cover 56 is recessed on its lower side to receive the member 54. When screws 62 are tightened, the cover 561s forced downwardly carrying member 54 with it. 'I'he turned-down edge of member 54 pinches the fold.` of material which overlaps member 5.2, securing the body 50 in place.

The tube C enters the cover 56 at therear, out of the way of the operator. The button 34, for a right-hand device, is to the right for operation by the forenger. At the left front, the cover` 56 is provided with a hook 62 of appropri-Y ate shape.`

To. the outlet extension 25, there is attached a rubber tube l0 which passes downwardly through suitable openings in

members

56 and 54 and body 50 and terminates just within the bottom Working surface of the body 50. Itis readily under-- stood that with air pressure built up in the reservoir A, it is merely necessary to depressA the L button 34 with the foreinger until the desired quantity of cleaning iluid ilows on tothe working surface via the tube J.

In Figs. 8, 9 and 10 I show a preferred embodiment of the applicator, which is generally designated as Bl'. rIhe applicator BI` comprises a stamped metallic hollow casing whichV comprises a top portion 'Hll and a flange 72, and -a cover partially enclosed sponge '14, which is adapted t0 engage the surface to be cleaned. Within the sponge 74 in the casing is a valve 22 of a construction similar to the valve illustrated in Fig. 5. At each of the short ends of the flange 'I2 is an outwardly extending ridge 15, which is adapted to receive a spring, generally designated as D. The spring is of general U-shaped formation having legs 18 and 80. The ridges 'IS on the ilange 'l2 are aligned, and the springs likewise are aligned. The legs of the spring pass in the tubes 82, that is to say, each of the legs 18 of. each spring D passes into one tube 82, and the other legs 8U of each of the springs D pass into the. other tube which passes longitudinally through the sponge. The tubes 82 are intermediate the sides of the sponge and, therefore, prevent the sponge 'i4 from being pulled out. A strong pull, however, will release the springs, but under ordinary working conditions the sponge will notpull out. l

Along the side of the flange 'l2 isan outwardly projecting extension 84 which is for the purpose of providing a grip for the person handling the applicator. A hook 86 is attached to the other side ofv the flange 'I2 for the purpose of hooking the unit in position. An opening 88 through the sponge permits the passage of iluid from the valve 22.

From the foregoing description, it will be apparent that this cleaning device is comparatively simple and that the parts may be economically made and assembled.

Although my invention has been described in .x considerable detail, such description is. intended as illustrative rather than limiting, since the inventionV may be variously embodied, andA the scope of the invention is to be determined as claimed.

I claim as my invention:

A cleaning device comprisingk an applicator having. a.relatively thick sponge body, a base for receiving said sponge member, said base comprising. a metallic member having a flange with outwardly extended indentations, and a spring Within said` sponge adapted to engage in said flange indentations whereby the spring. will be resiliently held in a lockedposition.
