John B. Gaskins, Atlanta, Ga., assigner of onehalf to Aaron Arthur Wiseberg, Atlanta, Ga.

. Application December 1, 1932. serial No. 645,291

- 3 Claims.

This invention relates to spotting buiers and is primarily designed to provide a complete unit adapted for the uses specied.

The construction shown herein is an improvement over the spotting buffer shown in application Serial Number 632,047, filed by me September 7, 1932. v

In my previous application above referred to the device described therein was primarily in-A tended as an attachment while the instant invention contemplates the construction of a complete unit.

Referring to the accompanying drawing:

Fig. 1 is a vertical elevation;

Fig. 2 is a vertical elevation showing the device in operative position, and

Fig. 3 is a horizontal section.

The numeral 4 designates a bottle or other container for the cleaning uid, having a slightly reduced neck portion`5 provided with threads 6 on the exterior thereof. A plug'stopper 7 of cork or other suitable material is slightly tapered to t the interior of the neck 5 and has a central aperture 8 for the reception of a tube 9 The tube 9 terminates in a bulb 10 forming a reservoir 11 communicating with the bore 12 of the tube 9.

The wall of the bulb 10 is pierced by apertures 13 and 14, the diameter of the aperture 14 being greater than the aperture 13 for a purpose hereinafter explained.

The upper face of the stopper 7 is convex as indicated by 15 and carries a buffer cloth or pad 16 of suitably absorbent material which is removably held in place upon the face 15 of the stopper 7 by a cap 17, having threads 18 forengagement with the threads Y6 of the container 4, andralso being provided with a central opening 19 through which projects a portion of the convex stopper face 15 carrying therewith the buffer 'cloth 16.

' convex to conform tothe contour of the face 15 of the stopper 7.

It will be seen that, by manipulationv of thev relation and upon removal of such cap the cloth 16 may be removed for replacement andv similarly the stopper 7 may be likewise removed for the The outer portion of the cap 17 is also f relling of the container 4, upon depletion of its supply of cleaning fluid.

With the device in the position shown in Fig. 1 the container 4V is lled with cleaning fluid to about seven-eighths of its capacity. This cleaning lluid being heavier than air Ywill enter the aperture 14 of bulb 10 displacing the air within the reservoir 11 through the aperture 13.

When the device is in position for use as shown in Fig. 2, the cleaning iiuid travels downwardly through the bore 12to the tube 9 and saturates the buffer cloth 16 supplying suicient cleaning fluid for spotting operation. While in use no more cleaning iluid is supplied until the device is again placed in the position shown in Fig. 1 when the operation of filling the reservoir 11 is repeated.'

By constructing the device as herein described, there is formed a complete spotting buffer unit which is elicient in operation and convenient to an automatically filling bulb reservoir on said tube, a buffer cloth adjacent the open end of said tube andmeans for removably holding said tube, stopper and cloth in operative relationship.

2. In combination, a container for cleaning fluid, a buier cloth, means for automatically supplying iluid from said container to said cloth in predetermined quantities, said means comprising a tube, a reservoir on said tube, suchy reservoir being adapted to supply uid only when the entire device is in inverted'position.

3. In a spotting buffer in combination with a container for cleaning uid, a buffer cloth, a stopper for such container supporting said cloth, a tube carried by said stopper for supplying prede,-

termined amounts of cleaning fluid to said buffer cloth, areservoir on said tube and provided with means for the admission of cleaning uid and the expulsion of air and means for removably securing said cloth inrposition upon said stopper.
