In the accompanying drawings I have shown `ene form of apparatus embodying my invention. This form is shown by Way of illustration merely and is intendedA to illustrate the idea of my invention,without necessarily limiting myinvention to the construction shown.

In the drawings, Figure lis a sectional elevation of the apparatus, the front of the case being removed. Fig. 2 is a plan view thereof. Fig. 3 is a diagram of the circuits, and Fig. 4 is a section through the lamp and instrument-carrying holder. Fig. 5 is a detail side View of the device for holding a spatula or other instrument. This figure also shows the line 4 4 on which the Asection Fig.v 4 is In the drawings, a is a suitable casing in which are journaled suitable spring-barrels b c. Insulated conducting-wires ef g 7e are provided for supplying current to suitable electric lamps 1l j. One of the wires, let us say e,is connected to a conducting-baud Zof the spring-barrel b, andthe other of the said wires fis connected to a conducting-band m of the said spring-barrel. In like manner the wire g is connected to the conducting-band n of the other spring-barrel and the wire k connected to the other band o of the spring-barrel c. 'Ihe contact-brush m',carried by the casing, bears upon the band m; a contactbrush Z', carried by the casing, bears upon the band l; acontaet-brush fn', carried by the casing, bearsupou the band n, and a contactbrush o', carried by the casing, bears upon the band o. The contact-brush n' is connected to a contact-plate p by wire q, (seel Fig. 3,) and the contact-plate Z is connected to the contact-plate r by wire S. The battery is herein shown as ordinary dry cells t, connectedin series, and one terminal thereof connected to the wire q by a suitable plate or contact 1J and the other terminal connected to the plate fr. A suitable pivoted switch u is provided for closing circuit between the contacts r and o', and another suitable pivoted switch lu is provided for closing circuit between the contactp and the brush m. The lamp carrier or socket i', which carries the lamp e', is provided with a suitable hook or fastening device 2 for hanging the lamp upon the clothing of the physician. The lamp j-is carried in a suitable socket j' in the elongated holder w. This holder'w, as shown in Fig. 4, consists'of an external shell .72, forming one terminal of the device,.and an interior rod j3,

which is adapted to contact with the central contact of the lamp. The elongated holder w is seated on a plug or, which is likewise formed with a central contact and a surrounding contact. The elongated holder w is provided with -a tubular socketgj4 for receiving the Shanks of suitable surgiml instruments and likewise with a pair of oppositely-placed jaws or flanges '7'5 for receiving the curved shank of a spatula or other instrument 3". These jaws extend longitudinally of the body w. l

As illustrating the convenience of my device, let it be supposed thatuthe surgeon dcsires to examine a patients throat. IIe hangs the lamp e' upon his coat or forehead, using a band around his forehead to .receive the hook i2 and by employing the combined lampholder and spatula can illuminate the laryngeal cavity of the throat directly by means of the lamp carried in the same instrument as the spatula and also by means of the lamp fi. It will be observed that the case (L is divided into two chambers by the partition a. The lower chamber a2 contains the batteries, and the upper chamber a3 is adapted to contain the other parts of the device. pose the wires which wind on the spring-barrel after the manner of the Hartshorn roller Vvpass freely through the apertures ai* in the partition a', so that by uuserewiug the elongated holder Iw from its socket m, unserewing 'the lamp j and placing it between the resilient jaws y, and removing the spatula j from the elongated holder fw all the parts which are not contained within the chamber a2 lamp, thesaid conducting-wires being elec' trically connected to terminals carried upon an automatic spring-barrel carried by the casing and circuit connections between the battery and spring-barrel, substantially as described and for the purposes set forth.

2. In an electrical apparatus for surgeons may be packed into the chamber a3 and the swing-- mg c over a5 may be swung down and securely' use, the combination of a casing divided into two chambers, a battery contained in the lower chamber, a spring-barrel, in electrical connection with said battery, electrical conductorsalso connected to said spring-barrel and anelectric light connected to the said electrical conductors and adapted to be housed in the upper chamber of the structure.

3. In an electrical apparatus for surgeons use, the combination of a casing, an electric battery carried thereby, a spring-barrel provided With insulated cond ucting-wires-in electrical connection with an electric lamp, contact-brushes adapted to maintain a rubbing contact with the spring-barrel and electrical connections between the battery and said brushes.
