To LU efe/tom 25 may concern.'

Be it known that I, J AMnsI-I. ROBNETT, a citizen of the United States, residing at AL. bany, in the county of Linn and State of Oregon, have invented certain new and useful improvements in Projecting-Lamps, of which the following is a specification.

The present invention relates to iinprove.- ments in projecting lanips, and embodies certain novel features andv combinations and arrangements of parts including a portable,.

self-contained electric lamp and an adjustv2 is 'a rear view of Fig. l.

able projector or reflector for the light arranged in proximity to a holder for a depressor. The depressor is adapted for use in examining the throat, and the lamp and its auxiliaries are. therefore. especially designed to throw or project the rays of light from the lamp toward the back of the throat while being` examined by a physician or surgeon in medical or surgical practice. It should be understood that the depressor is to be applied to the tongue for the purpose of holding .it down to give free access to the throat. In the accompanying drawings I have illustrated one comple-te exainpleot the physicalembodiment of my invention constructed according tothe best mode I have so far devised tor the practical application of the principles of the invention, and the embodiment illustrated has proven highly successful in actual practice.

Figure 1 is a perspectiveview of the rojecting lafn'p and accessories complete. 411g. Fig. 3 is a. front View of the 'jacket or casing with the lamp and spatula holder` removed. Fig. 4 is a side elevation, partly in section of the spat ula holder.

I have illustrated the invention as utilizing a well known torni ofportable, self contained electric lamp l equipped with the usual dry battery,`the light bulb 2, and push button 3 for making contact and ignitinggt the lamp. f

ln adapting this, or any lother suitable style oi lanip for use with my improved 'deviccs, ly employ a jacket or casing 4, which in'this instance is elliptical in cross section and open at both ends. This casing is made of suitable material such as nickeled brass, having at one side an Open slot extending its entire length, as indicated at 5 and the slot is bounded atits sides by angular flanges 6, (3. A pair-,of integral straps 7, 7 extend across the slot, ilush with the bodyvof the casing, and their ends are passed through slots and turned up about the flange (3. Ihese straps prevent the casing from spreading, and also, in connection with the danger; 6 and-6 `provide a receptacle for the slidable blade 8 of the spatula holder 9.

The general constructie-n ot' the spatula 10 and its holder 9 are illustrated in Fig. l, .but Fig. fl: ,more Glearl-yillustrates the construction of the holder per se.V The holder 9 -is provided with a pair of fianges l0 between Which the spatula l0 is to be inserted and held, and the holder hinged to the blade 8 between two ears l2 turned up from the blade. of the blade a handle 13 and 1d is respectively forined, and the handle 13 .in addition to its usual function furnishes a stop to pre- -vent excessive upward swing ot the spatula holder.

On one side of the casing, its metal is stampedy out to form a trough l5 in which the spring 1G is secured. The trough provides for and accommodates the button 3 when the lanip is pushed into the casing,y and near the upper end of the trough an opening.; 17 is made so that access may be. had to the spring or resilient blade i6. By pressure on the blade (from the thumb or finger) at this` point, it will be readily understood that the lanip is lighted.

Diametrically opposite and across the casing 'from the spatula 10 is located a reflector or light projector 18 which includes the usual mirrorlil to which is attached a stein Q0. This rellector is ot' standard niake and may be procured in.`open market, but I adapt it for special use with my lan'ip casing, by providinga pair of springs` tongues At the upper and lower ends :21, integral with and struck up from the body of the casing et. These tongues are bent to contorni to the stein 20, and have suflicient resiliency7 or elasticity to securely clarnpthe ,stein in adjusted. position, but -at the saine time allow the stein to be moved vertically to adjust the reliector. An extension 22 is formed at. the upper end of the thehun-and the slot 23 therein provides a seat for the bent upper end oit the steinv when the reflector is pushed down to its extreme position, the reflector being;r in position a1; the front. ot the extension` and the stein projecting out to the rear through the slot.

The utility of the device will be apparent.

'leslv llO VIn operation the casing is grasped in the hand with the thumb or linger on the spring The spatula having been adjusted, it is inserted into the mouth rto depress the tongue, the Contact button is pushed by pressure on the spring 16 and the light is flashed from the reeetor in the direction of the arrows to the rear of the mouth or I v throat. It will be understood of course that the device is capable of use for other purposes, and the above is Acited simply as an exenipliicationA of its use.

What claim is l. A lamp casing comprising an integral metal piece bent to shape having an open side with angular flanges and straps extend- -ed across the opening to'recleive and retain JAMES H. ROBNETT.
