To all whom t2 mayconeern." l v L Y Beit known that I, yCHARLES I. SiroLoFF, a ,citizenA` of the United States, and resident of New York cit inthe county of New York and Staten New York, havel invented certain new and'v fusetul Improvements in Saliva-Ejectingy Devices', ofv which the fol- This inventionrelates toy improvements in the means for ejecting saliva from the mouth during dental and surgical operations,- and more' Y particularly to that typel of salivaeje'cting device wherein the sucti'onpressure v created by a vacuum producing apparatus is utilized, as' the ejecting medium.A
I An object of my invention is to provide Va tion, aiiiordin'g the highest efciency of functioningr for the existent suctionv pressure.
"pr`es`sure', when this pressure! isWea'l, `isV a i That is', by reason of its refinement: and simplicity of construction, the loss 'of suction minimum. Furthermore, through the pro-4 '.vision of a pressure regulating" attachment,
the suction pressure may also be decreased, at
will, should it prove great "enough to causeV discomfort.
notlier'object of' my invention is the provision of a positive means of c'onnectionbetween the mouth-piece andmain body yof fthe device, r'zvhich".v means ailso provides ,piaga-inst unintentional. disengagement of the i said mouth-piece andl body. further ob-V ject is the provision of a rubber guard to eliminate the unpleasant Jfeeling caused by theY direct contact between the mouth-piece l and teeth.
i -Other objects Aof this invention, not -here= A inafte particularlyenumerated, will become apparent froml the detailed description iollowing and from theaccompanyrng draw ing, setting forth and illustratirlgy the novel construction and arrangementand` combination of parts of a preferred embodiment of my invention. v l,
`In the a'cc'ompai'iyingy drawing:
Figure jl is a perspectivepview showingl an embodiment of the saliva-'ejectng device forming the substance of my invention.
Fig. 2 is an'elevational view in section of the device. y Y Figlj is a fragmentary view in elevation of the rnouth-'piece of thed'evice".
The saliva-ejecting device herein describedandV illustrated is of the style especially' aptheinlfet openings 4e, herein shown arbitrarily,
tour 1n number, through' .which the sali-va' plicable for use in dentaloperations 'The device lcomprises two sections,` ay mouthpiece, iorming the upper lportion ofthe dereferring to Fig. 2, is formed of a tube 2,
top', adapted to rest generally in the; region of theV mouth beneath the tongue.4 The extremity of the beak 3' is provided -with is drawn from the mouth.l About that 'portlon yof the bea-k thatwould come in contact with the teeth, fispositioned the grooved flexible rubberiguad 5: pTOVided asf a means for' diminishing the dscomfortable feeling.. caused by thecontact of the mouth-Piece against the teeth, and for preventing undue.'
sliding vof the beak in 4the mouth.-
The groove `-19 is provided in the Vierm-ation of teeth' of VAthe *lower jaw; The 'guard/5f.. is here shown o "f slit` construction, permitting it to be' readily` vslipped trom'the `mouth-ipieee.Y
tremity, 'in the sleeve 6, adapted toIrv engage in a sliding iit'over the upper portion ofthe body l', here shown shouldered, r-iferringv to coupling'. The lower end of' the male`member` 9 terminates in nipple extension, which 'in turn is adapted to be coupled to the flexible tubing 8, and vis permanentlyv attached thereto bythesecuring collar 10 and rivetsv 11. v y tV The pin -12 of the clutching means is shown, reference beingha'd to Fig.- 2,iixedly mounted in the body of the device,.proxi 105' mating the top.- An ordinary screw, round or iilistered head, maybe used orthispurpose, the joint being preferably soldered'.y v
On the top of the body l, reference ybeing had-to Fig.vv 2,-therevisimnly positioned v`a A u 7 the guard' L5, *telco-operate with the Contact over1 vor-Lrei'n'oved y 1 @+10 1 The tube .2 ',terminatesfat' its loweriex' nov es' ternally threaded male member 9'. ofthe compression-straining member, formed of the rubber washer 13 attached over the Strainer 1li, the strainer 14 being fixed on the seat provided for it on top ofthe body Although the strainer Vand washer maybe permanently attached together, it would be more preferable however, to adapt the strainer to be permanently seated Von the body 1 using solder or a screw securing means, and'tol adapt therubber washer to snugly fit against the shoulder of the sleeve '6.ofthe mouth-piece, thereby simplifying the construction. The purpose of the strainer 14; in the position as shown, is to act as ameans for catching any solid substance vthat may be drawnin through the inlets 1l. lTo connect the mouth-piece with the body 1' of the device, the mouth-piece is manipu- A lated so that the slot 7 isbrought inr engagement with the pin 12, and the mouth-piece twisted around so that the pin rests .at the topmost extremity of the slot. It will be perceived, reference being had to F ig. 3, that f Y theslot 7 is angled obtusely,.and terminates in a-nest-like rest. The engagement of the slotted portion of the mouth-piece with the pin in the body will cause, at the coinmencement of the twisting action of the g mouth-piece, a compression of the. rubber portion of the mouth-piece and the top of the washer 13 between the opposing shouldered 'body 1. rIyhis compression pressure of the rubber washer 13,'when the mouth-piece and body of the device are locked inengagement, 'is equivalent to theV force tending'k to hold the mouth-piece and body in this-relationship. By proportioning the degree of angularity of the-angled slot 7 with the valueof thickness and quality of the rubber washer 13, this force tending -to hold the mouthpiece and body locked, can be varied to suit.
The suction pressure relieving arrangement, here assumed of thecharacter of a tappet valve, is shown disposed, rreferring to Fig.` 2, centrally inthe wall of the body 1.
fThe opening positioned through the wall of the body is shouldered to provide the seat 15 di forthe spiral spring 16. The valve actuating means comprises the tappet 17, threaded to the push-button 18. When the push-button is actuated it will act, against the tension of the spring 16, and force the tappet 17 from its seat This will result in the -introduction of a bypath for drawing air into'the passageway through the body 1, and so relieve, i. e., decrease, the suction pressure acting at the inlet openings 4.
From the construction of the device,reference being had to the drawing, it will be noted how readily .both the ymouth-piece and body of the device may be disassembled and sterilized. Y f
Although there has been described in the foregoing, a practical construction embodying the principles of my invention, various modifications in detail will be apparent to those skilled in the art without departing from the scope of the invention, as set forth in the appended claims.
l/Vhat I claim as new, and desire to secure by Letters Patent is:
