EDWIN B. Trzzann, or DAYTON, oHIo vSURGICAL INSTRUMENT.

Application led May 17, 1,911.

To all whom t may concern.' l

Be it known that I, EDWIN B. TIzzARp, a citizen of the United States, residing at Dayton, in the county of Montgomery and 6 State of Ohio, have invented certain new and useful Improvements in Surgical Instruments, of which the following is a speci'- fication.

My invention 'relates to improvements in dental and surgical appliances and particu-l larly to an illuminating device especially adapted to the use of dentists but also suitable for use by other practitioners.

The object of the invention is to provide a simple form of lamp and support therefor by which the lamp may be readily supported in the mouth of the patient which will not only be cheap in construction but 'eficient in use,convenient in form, easily and readily adjusted, and unlikely to get out of repair. f

lVhile applicant is aware that it is not new to support mirrors or reflectors within the mouth o f the patient, such devices are dependent upon an external source of light and-the operator is hamperedin hismovements about the patient and in his use of instruments by the necessityof keeping his body, hands, and instruments out of line between vthe source of light and the reflector or mirror. Furthermore, when employing a reflector or mirror the lighted area is not 'constant Ain relation with the point being operated upon. When an external source of light is relied upon and the light reflected by a mirror in the mouth of the patient upon a' particular spot, any movement of the patient will vary the angle of incidence` and reflection thereby varyingA the direction of the reflected light. i

4'.lhe'p'resent invention is designed to over- 'come these difficulties by providing a source of light, i. e., a small electric bulb'and means for supporting the'electric bulb ata conf venient point within the tient, fixed `in relation with the point operav ated upon, thus permitting both the voperatorand patient unlimited freedom in their movements.

With the above primary andl other incidental obJects in view, as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operatiomor their equivalents, as

hereinafter described and set forth in the claims. A

Referring to the. drawings, Figure 1 isy a` perspective view of the assembled lamp and its support. Fig. 2 is a perspective view'of the support in an inverted position. Fig. 3

is a perspective view of the lamp engaging member. v

Like parts are indicated by similar characters of reference throughout the several views. v

Referring to the drawings, 1 is aminiature electric bulb of any suitable type or construction adapted to be engaged within' the socket 2. The lamp l is supplied .with current from any suitable source with which it is connected by a suitable flexible conductor cable 3. y

To stationarily support the lamp 1 in its adjusted position within the mouthof thc patient, there is employed a tooth clamp 4 of ordinary form adapted to :engage the opposite sides of a tooth conveniently located in relation with the point of operation.

A convenient and simple form of the lamp attaching means comprises an annular spring clip 5 from which projects a T shaped tongue, the head 6 of which is bent.

into a plane at right angles with that of the stem portion 7 l Lateral 4wing portions :8 are preferably provided on; the stem portion 7 and are curved to correspond with the interior of the varched portionl of the tooth clamp 4I' While itis not essential that the wing portions 8v be employed, such wlng portions assist in securely anchoring the ata` tachment device upon the tooth clamp.

shaped tongue are.- bent substantially at right angles to the main portion of the head 6 to form tips or wings`9 which engage-over l the exterior of the arched portion of the tooth clamp, as is clearlylshown in Figs. 1 and 2. In engaging the device with the tooth clamp the T shaped tongue portion the clamp where it is held while the socketl 2 of the lamp 1 is inserted through such clip The extremities ofthe headv 6,V ofv the T` operation.

- and a lamp detachably engaged Within the E tion 6 of the T shaped tongue and the tips or Wings 9 thereof engage one edge of the archof the clamp While the upturned spring clip 5 4engages the opposite edge of said arch thereby preventing lateral displacement. lt is thus seen that the lamp is firmly and securely engaged With the tooth clamp which in turn is engaged with the selected tooth thereby maintaining the light in a convenient position to illuminate the point of Having thus described my invention, li claim: I

l. [A dental appliance comprising a tooth clamp to be engaged .with a tooth of the patient, and an electric lamp secured to the tooth clamp aii'ording a source of light located Within the mouth of the patient.

2. .A dental appliance comprising, a tooth clamp to be engaged with a tooth'- of the patient, a socket member'carried thereby,

socket aording a source of illumination located Within the mouth of the patient.

3. ln an appliance of the character described,- a lamp support adapted `to be positioned Within the mouth of a patient, and a lamp carried by the support Within the mouth of the patient affording an original source of illumination therein.

4. ln a surgical instrument, a dental tooth clamp, anilluminating member, a securing member comprising a receiver for the illuminating member projecting above the arch of the tooth clamp, a lateral projecting shaped tongue carried by the receiver projecting beneath the arch of the clamp, angular tips on the extremities of the head of the T shaped tongue engaging the exterior of the arch at the edge opposite the receiver.

5. A dental appliance comprising an arch vshaped tooth clamp and a substantially U shaped spring lamp clip, said arch shaped clamp and spring clip being engaged one with theother in reversed relation.

In testimony whereof, li have hereunto set my hand this 13th day of May, A. D. 1911. lED`WllN B. TlZZARD.
