A- miniature electric lamp or bulb is mounted in the i `body and means is provided for supplying current to the said bulb. Also means is provided for turning the body with relation to the saddle and the rest.

ln the accompanying drawings :v-'Figure l is a perspective view indicating the manner in which the device is applied to the mouth of a patient. F ig. 2 is a side elevation with parts in section of the device. Fig. 3 is an elevation ot ythe device showing the same atv a right angle to the view as shown in Fig. 2.

The combined mouth prop and illuminator comprises a body l which is pivotally mounted upon a saddle member 2 adapted to straddle the teethv of a patient. A meml bei1 2 is provided at the under side oi' the intermediate portion with a suitable cushion 3 oi' any material as for instance cork or the like. The cushion 3 isheld in position in the member 2 by means or inwardly disposed ribs t formed at the opposite side portions 4 of the member.

An electric light bulb 5 is inserted in the body l and a cap G is detachably and turnably mounted upon the body 1 andis provided with a tube 7 through which electric wires 8 are passed and which leads to the y bulb 7 for the purpose of supplying electric current to the same.

A cup-shaped member 8 is provided with a threaded shank 9 which is screwed into the upper portion of the body 1. A cushion 10 is located in the cup-shaped member 8 and is adapted to bear against the teeth of the upper jaw oi' a patient when the device is applied as best indicated by F ig. 1 of the drawing. .he tiret cup-shaped member together with the attached shank and the cushion contained therein `constitute a rest for the upper teeth of the patient. The body 1 is provided at its lower portion and at the opposite sides of a line passing vertically through` its center with openings 11 into either one of which may be inserted the end portions of an angular tube 12. A pipe 13 is detachably connected with the upper end portion oi' the` tube 12 and a flexible tube 1i is connected with the pipe 13 and may be immersed in running water whereby a suction maybe created through the same ycausing the tube 12, pipe 13 and said tube 11i to serve as a drain for the saliva when the device is in position in the mouth.
