To all whom lt may concern:

Be it known that we. LAURENCE R. BARG- HanssN and CESARE L. CoNs'rANTrNr, citizens of the United States, residing at IVashington, in the District of Columbia, have invented certain new and useful Improvements in Saliva-Ejectors; and we do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cert-ain novel and useful improvements in saliva ejectors.

In carrying out our invention it is our purpose to provide a simple and eicient form of saliva ejector designed'to be inserted in the mouth of the patient in such manner as to drain off or remove the saliva and at the same time enable the dentist to use both hands while working on the teeth.y

A further object of our invention is to provide a device of this character which may be used in the mouth of the patient without causing discomfort or injuring the tissues of the mouth and gums. v

f With the above recited objects and others of a similar nature in view, our invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claim.

In the accompanying drawings: Figure 1 is a. perspective view of the saliva ejector embodying our invention. Fig. 2 is a view in side elevation. Fig. 3 is an end yview looking from the rear toward the front of the device. Fig. 4 is a cross sectional view taken through the saliva apertures of the ejector.

In the present instance, we so construct our device that it embodies a tubular stem or shank portion designed to beattached at its lower end to a tube of rubber or the like, which in turn is connected with the usual water suction pump so as to remove the accumulated saliva and water from the mouth of the patient through the ejector. The upper end of this shank is curved or bent and carries a tubular horizontally extending U-shaped member adapted to lie within the mouth of the patient beneath the tongue and of sufficient width to embrace the latter, this U-shaped member, when in use, occupying a position beneath the tongue and between the latter and the alveolar processes. The

shank or stem joins such member the forwardl ends of the plates are Hush with or vslightly below the upper plane of the member, as is clearly shown in the drawings.

.The branches of the U-shaped member are rovided wit-h apertures or openings formed 1n the upper surfaces of such branches adjacent the rear closed free ends of the latter. By such an arrangement the accumulation f of the saliva and water passes along the grooves or channels formed by the outer surface' of the. plate and the branches of the U-shaped member and such accumulation is then. drawn through the apertures out through the stem of the ejector. Furthermore, it will bel noted that the soft tissues of the tongue and mouth will not prevent the working ofthe ejector. That is, these soft tissues will not be drawninto and stop up the apertures so as to prevent the proper working of the instrument-for the reasonl that the plates fixed on the branches of the U-shaped member prevent the tissues being drawn into the openings and at the same time they hold the tongue out of the wayso it will not interfere with thedentists work.

Referring now to the accompanying.

drawings in detail, vthe numeral l designates a tubular shank or stem which extends vertically when the device is in o erative position, this stem being formed ci) any suitable material and is adapted to have attached at its lower end 2 a rubber tube `or pipe, which it is not deemed necessary to show, as it is of an ordinary construction. The upper end portionfof the stem or shank is curved rearwardly at 3 and'is approximately semi-circular in form so that when the device is in use the upper curved end of the 4shank eX- tends over the lower lip and front teethof the patient. The end of this curved shank merges into and communicates with the horizontally disposed rearwardly extending.

ico

erably closed as at 5. This tl-shaped member is designed to lic beneath the tongue and is sufficiently wide to embrace the latter. The top port-ion of each branch or arm 6 is perforated as at 7 to form an inlet for the saliva and water into the branch or arm,

this perforation or opening being preferably located adjacent the closed free end of the arm. To the inner side of each arm is tixedly attached, such as by brazing or the like, a plate 8 which is preferably formed of metal. Each of these plates is flared upwardly and outwardly, as shown at 9 and the top edge of each plate is cut or inclined forwardlyT and downwardly until the front or meeting ends of the plates lie substantially flush with or below the central portion or" the til-shaped member. By this con struction of the plates, a rest or support for the tongue is formed, the tongue lying on and between the plates, while at the same time curved grooves or channels 10 are forn'ed by the outer lower portion of each plate and the adjacent upper and inner portion of each branch or arm ot the U-shaped member. Along these channels the dropping saliva and water will flow to the pertorations through which said saliva and water may be drained by suction through the stem and rubber tube to the point of discharge.

We are aware of the fact that it has been proposed to construct saliva ejectors 'of this type, as is exemplitied in the patents to J. E. Jordan, 730,128, dated June 2, 190B and 951,130, dated March 8, 1910. But so 'far as we are aware, we are the first to prow-,de a salire ejector in which the horiaontally disposed U-shaped members lie entirely beneath the tongue and inside the teeth with the tongue embraced by and resting upon Leashes the plates, the latter being disposed and co1 related relative to the U-shaped member within the' mouth in such manner that channels are formed between the lower outer portions of the plates and the adjacent surfaces of the branches of the lll-shaped member so that the accumulated water and saliva will How along said channels to the openings in the upper rear portions of the branches through which openings said water and saliva may be drained through the ejector to the point of dischargelt is, of course, to be understood that our` Vejector may be 1r ade of any suitable material and that modications and changes may be made in the details of construction without depart-ing from the spirit of the invention or exceeding the scope of the claim.

`What we claim is:

A saliva ejector comprising a tubular shank terminating at its upper end in a rearwardly curved portion, a horizontally disposed lll-shaped tubular member communicating with the curved end portion of the shanli and of sutiicient Width to embrace the tongue, the branches of said U-shaped member extending rearwardly, the ends of said branches being closed, said branches having openings in the upper rear portions thereof, and an upwardly and outwardly flared plate txedly attached to each branch and forming channels in conjunction with the adjacent portions ot the branches, which channels lead to the openings in the branches.

in testimony whereof, we a'iX our signatures in the presence of two Witnesses.
