SPECIFICATION forming part of Letters Patent No. 793,134, dated June 27, 1905.

Application filed May 18, 1904. Serial No. 208,583.

T0 0]/ l/'mm it 71mg/ concern.'

Be it known that I, VILLIAM GEORGE HUGHES, a citizen of the United States of America, residing at Pittsburg, in the county Vof Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Cuspidors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in fountain-cuspidors, and relates more particularly to that class known as liushing-cuspidors that are particularly adapted to be employed by dentists, surgeons, and physicians.

The object of the present invention is to provide a cuspidor wherein a stream of water is introduced tangentially to the radius, thereby producing a centrifugal stream that will effectually cleanse and flush the cuspidor at all times.

My invention further aims to provide a cuspidor having formed in connection therewith an annular groove or waterway in which is placed an object which will conform to the inner Aface of said groove in cross-section, said object performing the function of interrupting the centrifugal flow of water, thereby causing a wave in the water that will be of greater volume than can be obtained by the ordinary overflow.

l/Vith the above and other objects in view, the invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described and claimed.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this application, and in whichh Figure 1 represents a vertical sectional View of my improved cuspidor, showing the connections in side elevation 5 and Fig. 2 is a top plan view with the shield 29 removed.

In the drawings the reference-numeral 1 represents a bowl having formed near its upper face an annular groove or waterway 2. AIn said groove is arranged a .rubber ball 3. A bell-shaped sleeve 4 is secured in the lower portion of the bowl, said sleeve having formed integral therewith a contracted tubular portion 5, which is cxteriorly screw-threaded, as shown at G. A cone-shaped strainer 7 is suitably secured within the bell-shaped mouth 4L, and a bracket 8, which may be pivotally secured or rigidly attached, carrying an integral collar 9, is secured to the bowl 1 by means of a sleeve l0, having formed therein an interior annular seat 1l., and is further secured on its lower face by means 0f a jamnut 12, engaging th'e screw-threaded portion G of the sleeve 5. A coupling 14 is also secured upon the screw-threaded portion of the sleeve which serves to connect thereto a flexible waste-pipe l5, communicating with the main waste-pipe. (Not shown.) A llexible supply-pipe 16 is secured in the coupling 17, which is rigidly attached to the sleeve 9 by means of a screw 18. To the other end of this coupling 17 is attached rigidly a supply-pipe 19, .having secured therein a valve 2() of the ordinary construction carrying a handle 21, said valve being provided with a twin coupling 22, one branch of said twin coupling communicating with an upright supply-pipe 23, which passes through a bracket 24, upon which is rigidly secured a tray 25. In the said upright pipe 23 is also secured a regulating-valve 26, and the upper end of the supplypipe 23 terminates in a bent-over neck portion 27. From the other side of the twin coupling 22 extends a curved pipe 2S, to which is secured an annular shield 29, having an annular raised portion .30, formed therein and terminating in an angularly-disposed downwardly-extending flange 31, which serves to deflect the stream into the body of the cuspidor, said annular shield 29 also serving the purpose of preventing the splashing of the water caused by the constant rotation of the ball 3 within the race or water way. The pipe 2S is tangentially disposed to the annular race or water way, whereby the centrifugal movement of the stream is obtained within the race or water way and also over the overflow and within the body portion of the cuspidor.

The operation of my improved sanitary device is as follows: The valve 20 being opened by means of the handle 21 will pemnit the wa- IOO ter to be forced and the same directed circumferentiallywithin the annular race or Water way, which `carry the rubber ball Aor other suitable body around said course continuously, thereby slightly interrupting lthe overiiow of the stream in the rear of said ball or other body and producing an increasedvok ume of water in advance of the ball or body and further producing a wave that will eHectually cleanse the cuspidor at all times.

The many advantages obtained by the .use of my improved device will be .readily apparent from the yforegoing description, taken 'in connection with the accompanyingfdrawings.

lt will be noted that various changes may Vbe made lin the details of construction with- Kout departing from the general spirit of my invention. For example, the annular shield may be formed integral with the body `portion of the bowl and a suitable iopening' 'and plug provided for the introdnction'of the iball or other body, if desired.

Having fully described my invention, what.

'I vclaimas -new,:a=nd -desireto secure l'by Letters Patent, is-

vin said waterway, and 'means whereby said body is Ycontinuously rotated :and moved around the waterway.

2. In la cuspidor, lthecombinationoi la lbowl 'reais having an annular groove Jformed therein, means `for .admitting water-to ,the groove, a Jree ball :arranged insaid groove, .and an annular deflecting-plate arranged over said bow-l.

3. In a cuspidor, the combination of a bowl having .a race termed therein, :a 'ba'll arranged so as to circulate in said race, an annular deilector-plate extending over said bowl, a water-inlet arranged tangentially to said waterway, and a suitable outlet. l

4. In a ilushing-cuspidor, the combination of a bowl having an annular race formed therein, a ball .arranged and free to circulate in said race, and a suitable support for said bowl, substantially as described.

n*combination Vof a bowl having a circular waterway l`aI-'ound `its Tim, a `suitable inlet connection fand outlet connection ior said bowl, -a yfree Eball arranged in the Waterwayof 'the bowl land :adapted -to rotate and also tocirculate varoomd the Lbowl said waterway under thle action of waiter 'owingftlirough Athe said in et.

In testimony whereof il affix my signature :in the presence of two witnesses. WLLIAM- GEGRGE Witnesses:
