9 Claims.

This invention relates to improvements in surface cleaning tools.

Heretofore, it has been the practice to clean at surfaces such as walls, with a trowel supplied with fluid under pressure. Such devices being rigid in construction are limited in their application to at surfaces and can not be used for cleaning irregular `surfaces such as moldings,

4window frames, automobile bodies and the like.

The object of this invention is a cleaning tool l for cleaning irregular surfaces.

`ln the drawings comprisingr two sheets of iine gures, numbered Figs. 1 to 5, inclusive, certain embodiments of the invention are set forth by Way ofV illustration only.

Fig. 1 is a plan View of the cleaning tool with the mitten in ghost outline associated with one suitable `form of pressure tank;

Fig. 2 is a cross-sectional view taken along the line 2--2 of Fig. l, looking in the direction of the arrows;

Fig. 3 is a plan View of a suitable form of mitten;

, Fig. 4 is a cross-sectional view taken along the line 4 4 of Fig. 3, looking in the direction of the arrows; and

Fig. 5 is a diagrammatic View of a system employing the cleaning device.

Like reference characters designate corresponding parts throughout the several figures of the drawings.

Referring generally to Figs. l and 2, the de- ,f vice includes a-wrist band which may be of felt-lined leather, provided with a series of ad justable `buckles 2l attached to said wrist band 20 in any preferred manner as by means of the rivets 22 and leather straps 23. A valve mecha- ,block 25 maintained in sealing contact by a -l gasket washer 26.1 The valve outlet is normally sealed off by a valve plunger 29 underl con- .trol` of a compression spring 311|.` The valve plunger 29, may be forced off its seat `by the valve `stein 28vunder pressure exerted by the push but- .ton 2l.

A rubber washer 3l seals `01T the valve sts-:m28 to prevent leakage of any liquid passing through the valve under pressure. A suitable jnipple `which may be` oi bra-ssor other material,

is `suitably secured in the lower valve 24 and is provided with a iiared hose connector 33 f or the hose line 34. A flared copper ferrulef ex- ,ltends 4through the hose line l34 winto, the lilared hose 33.

A flexible palm hose 35 is suitably connected to the valve outlet formed in the upper valve lock 25. The palm hose 36 may be attached to the valve block in any suitable manner as by means of a threaded ferrule 3l. The flexible palm hose is of suitable length to extend across the palm of the hand and along the index finger thereof, and is sealed oi at the distant end. A iinger band 38 which may be of elastic, is attached to the outer extremity of the palm hose 36 to enable the end oi the hose to be retained upon the tip of the finger as best illustrated in Fig. 5. A row of spray holes 39 are formed in the wall oi the palm hose 36 to enable the liquid cleanser which is continuously supplied from the hose it, under pressure, to be sprayed through the spray holes 39 so as to moisten the mitten te which encases the hand (see Fig. 5).

The mitten 40 may consist of two plies of terry cloth or other similar exible porous material, which may be folded in any desired manner, as by doubling the terry cloth along the line 49, to form a double ply of terry cloth, and then securing the two plies of terry cloth together by sewing a line of stitches 43 (Fig. 4) through the middle of both plies of the doubled-over material,

,at right angles to the line 49, then folding the Adouble-ply along the line of the stitches 43, to bring the free edges of all four plies di 412, 44 and 49, into registry, and securing said free edges of all four plies together by sewing the lines of 4stitches 46, 46 through all four plies to complete the mittenA 40. The mitten may be slitted at the wrist line at 82, and provided with a snap 'i and a hollow fastener 48, to enable the open end 82 of the mitten 40 to be fastened at the wrist so as to cover the valve mechanism carried y by the wrist band 20.

A pressure tank 50 including a pressure pump 5I, cover member 59, and pressure gauge I52, is provided with an outlet 53 for a hose connection for the opposite end ol the hose 34. The tank 50 contains either a suitable cleansing liquid 54, or a suitable rinsing liquid which is forced into the hose line 34 under pressure supplied to the pressure tank 5!) by means of the pump handle pressure, the push button 2l is pressed against the surface to be cleaned, the valve plunger29, opens and permits the cleaning liquid 54 (or the 3 rinsing liquid) to enter the flexible palm hose 36 with sufficient pressure to form a spray which passes through the spray holes 39 and meistens the mitten 40. The cleansing liquid 54 (or the rinsing liquid) passes through the ilexible porous mitten and is applied to the irregular surface to be cleaned. By careful manipulation of the push button 2, a critical control can be maintained over the passage of the cleaning liquid 54 (or the rinsing liquid) so that only a minute quantity of liquid is used which is insufficient to drip from the irregular surface or run down along the arm of the operator.

In the modification shown in Fig. 5, the cleaning device of Fig. 1 is shown as, ,one 0f a series, and each hose line 34 is adapted to be attached to one of the multiple taps12 of a valve controlled outlet 1|, or to one of the multiple taps 12a of a valve controlled outlet 86, of a pressure unit. The pressure unit may consist of a compressor 62 including a suitable motor E3 and a compressor 64 connected by a common pipeline 65 and pressure control valve 65 to la pressure tank 67 which may be supplied with the conventional pressure gauge ,BS and a removable cover member 69 through'which the cleaning liquid 54 Ymay be supplied to the flexible palm hose 3G of the cleaningdevice. Another pressure tank l is connected to the common pipeline 65 of coinpressor 54 thrOugh a Separate pressure control vajlve 85, Tank 7l) also includes a removable cover member 83 and a pressure gauge 84, and contains the rinsing `fluid 13 which may be supplied to the cleaning device under pressure through the outlet valve 86 and the multiple taps 72a. With the system of Fig. 5, several operators vprovided with cleaning devices are connected to the tank 61 containing the cleaning liquid 54 and other operators equipped with the cleaning devices are connected to the rinsing tank lil containing the rinsing liquid 13. The first group of operators would proceed to work over the surface to be cleaned with the cleaning fluid 54 and are then followed by the second group of operators who would apply the rising iuid 13 to the cleaned surfaces. The multiple taps l2 and 12a are separate lines, but they may be linked together through a shut-oir valve (not shown). This system is particularly useful for effecting the rapid elearning of large areas- The pressure applied to the liquid cleanser and wetting agent may vary according to conditions. Pi pressure of thirty pounds gives good results.

ljhe removed dirt is collected yby the mitten. When one face is soiled, the mitten may be turned over and also turned inside out until all four faces are soiled, when it may be replaced by a clean mitten. Soiled mittens may be washed out and used over until Worn out.
