- is a specification.
' This invention relates to cleaning devices and particularly to dry cleaning devices for removing grease and dirt spots from clothing of textile fabrics.
The object of the invention is to provide an improved cleaning device which is sirn ple, cheap and easy to manufacture, which Is durable" and not.liable to easily get out of order, which is provided with valve mecha- 'nism for regulating the flow of the cleaning fluid to thecleaninghead, and which is so arranged as to prevent now of said fluid except when desired and to also prevent leakage of the cleaning fluid to the outside of the device.
The invention comprises the construction and arrangement of parts hereinafter described and claimed.
In the drawings, Figure 1 represents a side elevation of a cleaning device embodyingthe invention; Fig. 2 is a sectional elevation thereof, showing the valve mechanism in the position .whch closes the reservoir; and Fig. 3 is a detail View of a modification corresponding to Fig. 2, and showing the valve device in the position with the reservoir open.
' The cleaning device shown in the drawings comprises a reservoir 1 for the cleaning fluid, which reservoir may be of any suitable shape and is shown as a hollow cylindrical member which may be of any suitable material, such as glass,.porcelain or the like, and is shown as a metal member provided at one end with screw" threads 2 to receive a pressed sheet metal cap or closure 3, having aknurled portion 3 for turning the same. Preferably a suitable gasket 4 is placed between the cap or closure and the reservoir 1 in orderto prevent leakage of the fluid through the threaded joint.
The cap or closure 8 is provided with a long tubular stem 5, one end of which is provi'ded with a square or non-circular portion 6, "and the other end of which is threaded exteriorly as at 7 and interiorly as at 8. Said stem has abore extending from end to end thereof, and is provided with one or a plurality of small side ports or apertures 20 to Specification of Letters Patent.

for example, may be an ordinary needle.
valve, but is shown as a rod 9 threaded into the stem and having a milled or knurled head 10 lying at the outer open end thereof. The tubular stein portion of the capor closure 3 is provided at its opposite ends with valve seats 11 which cooperate with two valve members, marked respectively 12 and 13, the first of which may .be an integral portion of the valve rod 9 and the other of whichis shown as a conical valve member threadedonto the inner end of said rod.
The cleaning head comprises a cup shaped pressed metal member 15, provided with a suitable cap or closure 18 having a knurled portion 18* for manipulating the same, and one or more strengthening beads 18, and in which member is located the cleaning member 16. Said cleaning member preferably consists of two or more strips or bands, one, marked 16*, formed of woolen or other suitable textile fabric and the other, marked 16 of bristles or suitable hair cloth, which acts to space the layers of wool apart so the liquid'flows readily through the porous cleaning member, and which bristles or hairs also act as a brush during the cleaning operation. The cleaning head is carried by the tubular stem 5, and for this purpose the cup is provided in its side walls with two apertures, one of which is square to fit over the squared'portion 6 of said stem to prevent the cup from turning thereon. The several plies of the cleaning member 16 are also pierced to enable the stem to be pushed clear through said head, so that it projects from the opposite side thereof, which prevents loss of the cleaning member 16. The head is clamped to the device by a suitable nut 19 threaded upon the external threads 7 of the stem 5.
In use of the device the reservoir 1 is filled with a suitable quantity of cleaning fluid, such as gasolene or the like. In the position ofvthe parts shown in Fig. 2 the valve mem ber 13. is seated and communication between the reservoir and cleaning head is closed. To use the device the milled head 10 is turned until the valve 13 is lifted from its seat to permit the' liquid to flow from the reservoir through'the bore of stem 5 and the ports or openings 20 in the side wall of said stem. By turning the milled head 10 sufficiently far the outer valve member 12 maybe iorced against its seat to prevent leakage 'of the liquid through the end of the stem.. Cap-18 is removed vand the fabric to be cleaned is rubbed with the brush end of the cleaning member. The reservoir 1 forms a convenient handle for the device and enables it to be \readily' manipulated. After use the valve is closed the cap 18 is restored and the entire-device may be packed away without danger of any of the liquid leaking from the device and contaminating "anything with which it may come in contact.
The valve member 13 may be secured to the rod 9 by an ordinary lock nut, but preferably, and as shown in Fig. 3, said rod is provided with a fine bore 21 extending from end to end thereof and which is provided at its inner end with threads to receive a small tube 22 which extends .to a point closely adjacent the outer end of the reservoir 1. The chauuel'through this tube and the bore of the rod 9 are so small that gasolone or liquid will not readily leak therethrough, especially if valve 13 is closed.
However, the arrangement readily permits the passage of air into the reservoir so the cleaning fluid flows freely to the cleanling head.
What l claim is:
1. A cleaning device, comprising a cleaning head, a reservoir for liquid, a tubular conduit connected thereto and supporting said head, a hollow valve rod extending through said conduit and provided with valve means for controlling the flow of iquid to said head, and an air tube connected to said hollow valverod.
4 masses 2. A cleaning device, comprising a head having; a cleaning member therein, saidv 3. A. cleaning device, comprising a head having a cleaning member thereim'a conduit extending through said cleaning" member and arranged to deliver liquid thereto, reservoir at one side of said head communi eating with said conduit, and valves at opposite ends of said cenduit seating in opposite directions, one valve adapted to control the flow of liquid from the reservoir to cleaning head and the other to prevent escape of liquid fronrsaid conduit.
4. A cleaning device, comprising a head having; a cleaning member therein, a conduit extending through said cleaning member and arranged to deliver liquid thereto, reservoir at one side of said head communi cating with said conduit, valves at opposite ends of said conduit seating in opposite directions, one valve adapted to control the flow of liquid from the reservoir to the clean ing head and the other to prevent escape of liquid from said conduit, and means open able from the opposite end of said head controlling said valves;
in. testimony whereof, I have hereunto my hand. I
