DENTAL CUSPIDOR.

SPECIFICATION forming part of Letters Patent No. 597,384, dated January 18, 1898.

Application led November 2, 1896. Serial No. 610,871. (No model.)

To aZZ wir/om it may concern/s Be it known that I, GEORGE BOOTH, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Dental Cuspidors, of which the following is the specification.

My invention relates to improvement-s in dental cuspidors; and the object of the invention is to design a simple, cheap, compact, and convenient form of combined cuspidor and tumbler-rest in which the stand of the cuspidor may be placed close to the dent-al chair and the cuspidor readily swung into position before the patient; and it consists, essentially, of a hollow tubular standard having connected tO the bottolnend thereof a waste-pipe and at the top having pivotally swung thereon a suitable valve with radial hollow branch arms, on the end of one of which is secured the tu1nbler-rest and on the other the cuspidorin suitable form, and, further,of a water-supplypipe extending through the base of the tubular standard and provided with a valve near the floor and a faucet the stem of which extends up and is supported in a bracket attached to the standard, the said supply-pipe extending up through the center of the hollow standard which forms part of the waste-pipe to a chamber-casing supported on the upper end of the sleeve, from which casing leads a branch supplypipe to the cuspidor and also a vertical supply-pipe having a curved upper end for the supply of water to the tumbler, the parts being constructed as hereinafter more particularly explained.

Figure l represents a sectional perspective view of my improved form of dental cuspidor. Fig. 2 is a sectional det-ail of the ejector, to which the tube is *attached for drawing the saliva from the mouth. Fig. 3 is a detail view.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is a central supporting-standard which is formed hollow, as indicated, and B is the base.

C is a sleeve which is screwed into the bottom of the standard, and D is the bottoni of the waste-pipe, which is screwed int-o the bottom of the sleeve.

E is the supply-pipe, which extends centrally through the standard A and is provided at the bottom with an elbow e, through which extends a branch pipe e', which is connected to the main supply-pipe E. A valve e2 is provided which is provided with a long stem es, which extends upwardly from the valve through a bracket a, attached to or forming part of the standard, and is provided with a turning-knob e4. By having such a stem supported near the top of the standard it will bereadily seen that a dentist can without stooping turn the water on or oft.

F is a sleeve which is provided with an an nularshoulder f. ThesleeveFeXtends downwardly into the standard A as far as the Shoulder f, upon which it rests.

F and F2 are radial hollow arms situated diametrically opposite each other and provided with upwardly-extending elbows f and f2. 0n the .upwardly-extending elbow f2 is secured the minor basin G, provided with a perforated plate g. Upon this plate it is designed to place a tumbler or other suitable vessel for the reception of water, and the plate is made perforated, so that the water may drain through it into the hollow arm F2.

H is a cuspidor which is secured at the top of the elbowf. The cuspidorH is provided at the top with an annular chamber 7L, the bottom of which has perforations h', as shown. The top of the sleeve is closed in and has a cup t', the exterior of which is threaded.

J is a faucet the bottom of which is enlarged and extends down into the recess The pipe E extends upwardly into the faucet J, as indicated.

I is a washer which is placed beneath the lower end of the faucet and the bottom of the recess and surrounds the pipe E.

I isa screw-cap which fits onto the enlarged lower end of the faucetJ and is screwed down upon the threaded ou ter end of the cup, so as to hold the washer l tight.

J is ahollow chamber in the faucet, into which the top of the pipe E its. The faucet .l extends upwardly from the walls of the chamber J and has a downward bend, as shown, the bottoinof such bend being directly above the center of the basin G.

j is a branch pipe leading from the cham- IOO ber J'l to the annular chamber h, formed at the top of the cuspidor.

K is an ejecting bent tube which is connected to the water-supply pipe at the lower end of the faucet J and is preferably provided with a suitable tap 7c and a nozzle 7c', extending laterally out therefrom.

7a2 is a hole leading through the nozzle.

7a3 and 7a4 are plugs formed with tapered holes, the narrow portion of the taper being next to the hole 7a2. (See Fig. 2.)

b5 is a tube which leads to the mouth and is designed to draw the saliva therefrom. Vhen the water is turned on and passes through the bent tube K and conical plugs therein, I find in practice that the effect is to produce a vacuum between the plugs, and the suction thus produced by the flowing water draws the air out Yfrom the tube h5, which passes out with the water, thus producing a suction through the tube and consequently in the mouth of the patient, thereby removing the saliva.

Although I show the bent tube K as connected to the faucet J and leading down into the waste-pipe connected with the tumblerrest, it will of course be understood that such ejection-tube might be placed at any point sel is put on the perforated plate G, any waste water will escape out through the arm F2 and standard A. As the sleeve F rests loosely upon the top of the standard A it will be readily understood that the arm F', with the cuspidor H, may be swung very readily by the dentist to the desired position in front of the patient. As the arms F and F2 extend directly-out from the sleeve at right angles thereto it will of course be understood that the standard A may be placed in very close proximity to the dentists chair, and the utilityof my device is thereby greatly facilitated.

WV hat I claim as my invention isl. In combination, the hollow standard, the sleeve rotatably supported thereby,the faucet fixed to said sleeve, the supply leading centrally through said standard and sleeve and into said faucet, the cuspidor and tumblersupport arranged on opposite sides of said standard, the hollow horizontal arms extending in the same plane and supporting said support and cuspidor and having communication with the bottom of the same and the branch pipes leading to the support and cuspidor from a common chamber in said faucet into which said supply-pipe discharges.

2. In a dental cuspidor in combination the hollow standard supported upon a suitable base and having the waste-pipe connected to the bottom of the standard, a sleeve supported on the top of the standard, hollow branch arms attached to orformin g part of the sleeve, the tumbler-rest and cuspidor supported on the upwardly-extending elbows of the arms, the su pply-pipe extending up through the center of the standard and having a branch pipe extending from lthe bottom to the main supply-pipe provided with'a suitable valve, the cup-shaped recess at the top of the sleeve, the faucet fitting over the top end of the supply-pipe, the branch su pply-pipe leading' from the faucet to the basin, the lower end of the faucet being enlarged and fitting within the recess around the pipe, a Washer beneath the loWer end of the faucet and a screw-cap holding the sleeve and faucet together as and for the purpose specified.
