4 Claims.

This invention relates to apparatus for use in cleaning fabric and the like and more particularly to apparatus comprising means for sup-' plying cleaning fluid to the fabric to be cleaned and for scraping or rubbing the fabric to remove spots, such as hard paint spots, stains, etc. The vapparatus comprises a hand device such as used in dry-cleaning establishments in what isknown as spot-cleaning for the removal of paint spots and the like.

One object of the invention is to provide apparatus comprising a hand device including an improved scraping implement and means for supplying cleaning fluid to the scraping edge thereof. A further object is to provide a stationary container in combination with a hand-operated scraping device and a flexible connection from the said container to said device. A still further object is to provide a hand device comprising a scraper, a brush, and a valve control for regulating a supply of cleaning fluid from a remote container.

With these and other objects in view, the invention consists in the novel constructions and arrangements of parts hereinafter described, -illustrated in the accompanying drawings, and particularly pointed out in the appended claims,

it being understood that various changes in the forms, and minor details may be made without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Fig. 7 is a view corresponding to Fig. 1 but showing a modified form of the complete apparatus and with the hand device shown partly in section; and

Fig. 8 is a similar view showing another modification. Y v

,The hand device shown on the drawings comprises a hollow handle l carryinga curved nozzle member ll having a scraping edge l2 and having a discharge outlet l3 for the cleaning fluid. The device is also formed with a suitably inc-lined member H for engagement by the palm of the hand when the device is in use, as shown at Figs. 3 and 4. A socket member i is also provided for the reception of a flat faced removable brush l5, andthe arrangement is such that when the scraping edge I! is in'engagement with the surface I! being cleaned the brush i6 is clear of the said surface, and when the brush is in use as shown at Fig. 4 the scraper i2 is raised from the surface ll. The construction of the device is such that slight tilting or rocking movement .-of the hand very conveniently brings either the scraper or the brush into its operative position,-

sothat scraping and brushing operations may be conveniently performed without loss of time or. energy in changing from one operation to another. The device is also provided with a leather or other like strap l8 which passes over the back of the 'hand of the user when'the device is in operation and the arrangement provides a convenient grip to facilitate the scraping and brushing operations and the manipulation of the fluid control as hereinafter described.

In the form, of the apparatus shown in Fig. 1

the cleaning spirit or other volatile fluid as comnionly used for softening paint spots and the like is carried in an elevated container I9 which is inverted and supported from a yoke so that the fluid may pass by gravity through a restricted outlet 2| and: through a flexible tube 22 to the hollow member ll] of the hand device. The container i9 is also provided with an internal tube 24 extendingupwardly to a point above the level of the fluid when the container is in its inverted position, as shown in Fig.' l, and the external air inlet end of this member 24 is provided with a suitable regulating device 23 whereby the admission of air may be regulated to suit requirements.

As shown at Fig. 2 of the drawings, the hand device is also provided with a thumb-button 25 which is secured on the outer end of a stem 26 connected to a valve 21 which is held on its seat by a spring 28, and when the button 25 is pressed inwardly by the thumb the valve 21 is raised from its seat against the action of the spring 28 and cleaning fluid is' permitted to pass from the bore 29 in the member ID to a. bore 30 in the nozzle ll, so that cleaning fluid is delivered to the surface I! being cleaned. As is clearly shown at Figs. 3 and 4, the thumb conveniently rests upon the bottom 25 so that the supply of fluid to the cleaning surface is always under-complete and convenient control.

The modified form of appartus shown atFig. 7 comprises a fluid-containing tank 3| which is preferably located at a lower level than the hand device when in use. This container 3| is provided with an internal, dependent tube 22 extending to a point near the bottom -of the container. and communicating with a flexible tube 33 by meansof which fluid maybe supplied to a bore 34 in the hand device, which latter is also formed with a cylindrical cavity 35 containing a piston 38 connected to a stem 31 havingabutton 38' on its outer end, and having a spring 39 in compression between the said button 28 and the device. Between the said bore 34 and the cylindrical cavity 35 a non-retum valve 40 is provided, and a passage 4| leads from the cavity 35 to the nozzle ii and has a non-return valve 42 therein. the said valves 40 and 42 being provided with springs 43, 44 respectively, so that reciprocation of the piston 36 by means of the button 38 first forces air and then fluid outwardly through the nozzle H and causes a flow of cleaning fluid from the container 3| through-the tube 32 and the flexible tube 33, and by way of the valves 40 and 42 to the nozzle II. The container 3| may thus be located at a level lower than the working position of the hand device, and while airis admitted to the container 3| through a controlled air inlet 45, fluid may be raised by the pumping action above referred to so as to deliver a proper quantity as and when required to the scraping edge of the nozzle H. As there is no gravity feed from the container 3i, according to this arrangement, the possibilty of leakage'of the highly volatile and inflammable cleaning fluid is effectively prevented.

In the modified form of the apparatus shown at Fig. 8, a sealed tank 46 contains the cleaning liquid, and a flexible air tube 41 is connected to a cap 48 on the container and to a bore 49 in the hand device which latter is also formed with a cylindrical cavity 50 communicating with the said bore 49 and having a cup-leather piston i operated by a stem 52 having a thumb button 53 and a return spring 54. The bore 49is provided with a non-return valve 55 having a, spring 55 and as the piston 5| is reciprocated by means of a button 53 air is drawn inwardly through a vent 51, raises the valve 55-and passes through the air tube 41 so that pressure is exerted in the container 46 above the level of the cleaning fluid which is thus caused to pass upwardly through an internal pipe 58 which extends downwardly from the said cap 48 to a point close to the bottom of the container. From the pipe 58 the fluid is forced through a flexible pipe 59 to a bore 60 in the hand device, so that fluid is thus supplied by air pressure to the nozzle H. I

The nozzle II and brush ii are preferably attached to the hand ,device in such manner that they may be conveniently removed in order to permit replacement as these parts become worn out, and as shown particularly at Fig. 6 the nozzle ll may be provided with a set screw 6| adapted to contact with a hollow nipple 62 upon which the nozzle may be fltted. The brush '6 is preferably fltted into a tapered socket l5 so that it may be readily and conveniently removed for' replacement.

Although the drawings and the above specification disclose the best modes in which I have contemplated embodying my invention, I desire to be in no way limited to the details of such disclosure, for in the further practical application of my inventionmany changes in forms and constructions maybe made as circumstances require or experience suggests without departing from the spirit of the invention within the'scope of the "appended claims.
