JOHN W. COOPER, OF BUFFALO, NEW YORK.

FLUSH-CUSPIDOR.

Application filed December 23, 1907.

To all whom it may concern:

Be it known that 1, JOHN W. COOPER, citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Flush-Ouspidors, of which the following is a specification.

T he present invention has relation to the type of cuspidors designed most es ecially for dentists use, and which are supplied with a flush for carrying off matter thrown into the bowl so as to preserve a sightly appearance and avoid unsanitary conditions.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accom anying drawings.

Whi e the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in

i which:

Figure 1 is a vertical central section of a flush cuspidor embodying the invention. Fig. 2 is a horizontal section thereof on the line 2-2 of Fig. 1. Fig. 3 is a detail view of the rim portion of the cuspidor showing the saliva ejector, the supply pipe and the glass holder in 006 erative relation. Fig. i is a vertical centra section of the saliva ejector on the line ac -cc of Fig. 3. view of the rim portion of the bowl and the flush pipe, showing the parts on a larger scale.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The cuspidor comprises a bowl 1 having a hollow rim 2 and rovided centrally of its bottom with an out et from which a boss 3 is pendent. The bowl may be of glass, porcelain, china or other material commonly employed in the manufacture of devices of this and analogous character. The annular space 4 formed within the rim 2 is open at its inner side, as indicated at 5, said opening 5 being continuous and arranged intermediate of the top and bottom of the space i. A flush ipe 6 is arranged within the space 4 of the ho low rim 2 and is provided at intervals in its length with minute openings 7 for the escape of wa- Specification of Letters Patent.

bottom ortion of the annular space 4 and the openings 7 are arranged upon the side of the flush pipe facing the interior of the bowl and are located a short distance below the uper edge of the hump 8 bordering upon the ower side of the opening 5. The jets of wa ter escaping from the openings 7 impinge against the adjacent wall of the hump 8 and spread laterally and flow over said hum as indicated by the arrows in Fig. 5. The ush pipe 6 is nearly or quite of circular form, its extremities being spaced apart a short distance and closed by means of plugs 9, which are threaded therein and are removable to admit of the introduction of a swab or other device into the flush pipe for cleaning the same, should it become obstructed by mud or sediment or any foreign matter. The supply pipe 10 connects with the flush pipe 6 clear of its ends, the joint being effected in any substantial manner. The supply i e 10 is sectional, the parts being connected fiy means of a union 11, such as generally employed in water fixtures for coupling pipes and tubing. 7

A waste pipe 12 has connection with the outlet of the bowl 1 and is threaded to the lower end of a coupling 13, which is tapered throughout its length and is provided at its upper end with a flange let to encircle the lower portion of the pendent boss 3. A packing 15 is interposed between the coupling'l3 and the boss 3 to insure the formation of a tight joint between them. A thimble 16 of tapered form is fitted in the boss 3 and its lower end is threaded and receives the upper end of the coupling 13 which is screwed thereto. The upper end of the thimble 16 has an outer flange 17 which fits snugly'within a depression formed in the bottom of the bowl about the outlet. A packing 18 is interposed between the flange 17 and the bottom of the depression provided to receive said flange 17 so as to obtain a tight joint between the thimble and bowl. The opening of the thimble 16 is enlarged at its upper end to form an inner shoulder 19 which receives an outer flange 20 of a receptacle 21 placed within the thimble and coupling 13 and designed to catch gold and other metals to be saved. A stem 22 is arranged within the receptacle 21 and its lower end is fitted into an opening formed in the bottom of said receptacle. This stem is hollow and is provided at its upper end with a conical head 23 which ter in jets. The flush pipe 6 rests upon the i sheds water and prevents the lodgment or accumulation of any matter thereon. This head 23 also serves as a finger piece for removing the stem from the receptacle 21 when required. A cup 2 1 is fitted to the lower per tion of the stem 22 and snugly fits within the lower portion of said receptacle and receives particles of gold or other metal which may be removed from time to time by means of the stem 22, which latter may have its head portion 23 grasped between the thuiiib and finger of the hand. An overflow pipe 25 is connected at its lower end with the Waste pi e 12 at a point below the coupling 13 and is fitted at its upper end to the lower portion of the hollow rim 2 preferably at the point where a space is formed between the separated ends of the annular flushing pipe 6. The over flow pipe 25 is coupled by means of a union 26 to a nippleor short ipe fitted in an opening formed in the lower portion of the hollow rim 2. Should the outlet in the bottom of the bowl become choked by cotton or other accumulations, stopping the openings or perforations in the lower ortion of the receptacle 21, the water will be prevented from flowing over the bowl by means of the pipe 25 which affords a discharge therefor.-

The supply or service pipe 27 has connec' tion with the supply pipe 10, a globe valve 28 being provided to control the flow of water therethrough. A branch pipe 29, connected with the globe valve 28, is provided at its upper end with a valve 30 to which a water fixture 31 is coupled by means of a swivel oint to admit of said fixture being swung to a point over the bowl or to position above the glass holder 32; The glass holder '32 is of cup form and is adapted to receive a tumbler or cup. A bracket 33 attached to the bowl in any convenient and substantial way,- piv-' otally supports the glass holder 32 and also braces the upper ends of the branch pipe 29 and the waste 35 of the saliva ejector.

The saliva ejector comprises a valve 36 provided with a tubular extension 37 to which is fitted the body 38 of the ejector, said body having a nozzle 39 to which a flexible tube 40 is fitted, and which flexible tube carries the mouth piece or suction tube, not shown. A chamber 41 is formed in thebody 38 opposite to the opening with which the nozzle 39 connects. A nipple 42 is threaded into the extension 37 and is provided with a minute opening to project a fine stream of Water across the chamber 41 and create a vacuum or suction therein, after the manner of an injector, so as to" create a suction in the parts 39 and 40 to carry off the saliva from the mouth of the patient. The waste pipe 35 is coupled to the lower end of the body 38 by means of a union 43.

The water fixture 31 serves as a handle to the plug of the valve 30, and when said part 31 is turned toward the center of the bolt, the valve 30 is closed, and when turned to the leftto extend over the glass holder 32, the valve 30 is open and water flows from the fixture 31 to supply the drinking glass or other receptacle that may be placed in the holder 32 or held above the same. fl' hen the fixture 31 is turned to the right so as to face away from the glass holder 32, the valve 30 is open to the saliva ejector.

Having thus described the invention, what is claimed as new is:

In a cuspidor of the character specified, the combination of a bowl having outlet and provided at or near its upper edge with a hol low rim, said rii'n having an annular opening in its inner wall Inidway' of its top and bot tom,- and a finish pipe located Within the lower portion of the space of the hollow rim and provided at intervals in its length with openings arranged upon the side facing the inner wall of the space, said openings being sli htly below the plane of the upper edge of the ower part of the inner wall of said hollow rim.

In testimony whereof I affix my signature in presence of two witnesses;

JOHN TV. COOPER.
