PORTABLE CLEANING DEVICE.

Patented June 2U, rare.

Application filed March 27, 1915. Serial No. 17,471.

and useful Improvements in Portable Cleanmg Devices, of which the following is a specification.

This invention relates generally to cleantable device for discharging a liquid detergent under pressure which renders the same particularly useful for removing grease, oil,

. same by a scraping tool.

and the like from automobile and other en- "gine parts.

1 It is particularly desirable in repairing parts of motor car engines and like surfaces which may be coated with grease, oil, and dirt, that the same be cleaned easily and quickly without dismantling the entire mechanism and placing the individual pieces in a bath of gasolene or similar cleaning liquid. Furthermore, it is not always convenient or practicable to remove the grease with cotton waste or otherwise displace'the Therefore, the present invention contemplates a novel portable container or vessel for a cleaning liquid, such as gasolene, coahoil, or the like, which may be connected with a suitable source of compressed airsupply to force the detergent agent onto the surface or article to be cleaned through a conveniently inanipulated handnozzle.

To this end, the invention contemplates a substantial and practical construction of container or tank having a novel arrangementof air and liquid controlling valves which may be easily and quickly manipulated and minutely adjusted to regulatethe supply of cleaning fluid forced from the container.

While the invention is primarily intended for use in cleaning operations, it may be also provided with suitable instrumentalities whereby it may be readily converted and used as a blow torch.

With the above and other objects in View which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the invention showing the novel valve arrangement and brush nozzle. Fig. 2 is an enlarged detail sectional view showing the in-, terior construction of the tank and valve device. Fig. 3 is a detail sectional view of the discharge nozzle.

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

In the embodiment of the invention disclosed in the drawings, the same essentially comprises a suitable container or tank 1 which may be of any convenient form or size and preferably provided at its lower end with a base support 2 for permitting the same to stand on end when in operative position. To facilitate the handling and port ability of the tank, there may be provided a swinging bail or handle 3, and also to en- .able the tank to be filled with the cleaning liquid or fluid, the same is provided with a siliitable filler spout 4 having a closure p ug 5. v

Detachably fitted in the head 6 of the tank is a combination air intake and liquid discharge valve device designated generally by the reference letter V, and comprising'a hollow valve casing 7 formed with a central cap portion 8 and the oppositely disposed nipple extensions 9 and 10. The casing 7 als0'includes a hollow shank portion 11 which may be provided with suitable threads 12 tb enable the same to be screwed into the head of the tank, thus facilitating the fitting and Y removal of the entire valve device from the tank when repairs thereto are necessary. The greater portion of the shank 11 extends down into the interior of the tank 1 and has a plurality of air ports 13, thus establishing communication between the in terior of the valve casing and the interior of the tank. I I

Arranged within the valve casing 7 and extending through and beyond the shank portion 11 is a liquid supply pipe 14 which is of less-diameter than the shank 11 thus providing an annular air space or chamber 11 between the walls of the shank and the exterior of the liquid pipe. This liquid pipe 14 is preferably threaded at its upper end as at 15'so that it may be screwed into the central cap portion 8 of the valve casing,

trol a-port 20Iin' the pipe 14 which is in communication with a laterally disposed liquid delivery tube 21 extending into the,

nipple extension 10.

' In connection with the oppositely disposed nipple extensions 9 and 10 of the valve casing it will be observed that the former has fitted thereto an air intake valve 22 while the latter has fitted thereto a similar type of outlet or discharge valve 23. These

valves

22, and 23 when fitted to the valve casing as above explained cooperate therewith to provide an air pressure receiving chamber 24 and a delivery chamber 25 which are in direct communication with each other andalso in communication with the annular chamber 11.

In use the tank or container 1 is fitted with a suitable cleaning liquid, gasolene, coal oil,

or other fluid capable of removing grease,

' and the valve 22 is connected by means of a hose or tube toa source of compressed air supply. When the plug of this valve is opened, air will enter the. chamber 24 and pass down into the annular chamber 11 and out of the ports 13 thus forcing the liquid up through the pipe 14 and also through the delivery tube 21, and into the chamber 25 where it is ejected or forced out through the discharge valve 23 into suitable means for applying the liquid to the parts to .be sprayed and cleaned, such for instance as a flexible hose 26 having thereon a hand nozzle designated in its entirety by the reference 27. This hand nozzle 27 preferably includes a hand grip 28'and a stem 29 having at its open end a detachable discharge nozzle 30 which is preferably provided with a'wire brush or equivalent element for augmenting the cleaning operation.'

, From the foregoing description, it will be apparent that the novel valvedevice makes special provision for supplying a cleaning liquid to a hand nozzle under pressure, the volume of which liquid can at all times be easily regulated independent of a constant air pressure supply. In fact, where the ocsion demands, the liquid supply can be entirely cut ofl and thehand nozzle discharge only air or practically a solid stream of liquid may be discharged. Furthermore, this valve arrangement gives the present device another utility, namely, that of a blow torch, arid to provide for this adaptation of the device, the tank 1 has arranged therein a blow tube 32, the exposed end of which is normally covered during the use ofthe device as a cleaner by a blank plug or cap 33. However, this plug may be easily removed and any standard type of torch burner inserted in its place.

When the device is used as a blow torch the valve 23 is closed, and the port 20 of the tube 14 is also closed, and the blow torch element inserted in the end of the tube 32. The valve 22 is then-opened and put in communication with a compressed air supply, and the compressed air allowed to fill the tank to capacity. The valve 22 is then closed thus holding the liquid under ressure and rendering the device capable o discharging the usual igniting fluid for the torch.

Without further description, it is thought that the many features and advantages of the invention will be readily apparent, and it will of course be understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention or scope of the appended claims.
