ELECTRIC HEAD-LAMP.

Specification of Letters Patent.

Application filed December 14, 1915. Serial No. 66,689.

To all whom it may concern:

Be it known that I, RUBERT S. Boron, a citizen of the United States, residing in the borough of Brooklyn, county of King's,city and State of New York, haveinvented certain new and useful Improvements in Electric Head-Lamps, of which the following is a specification.

This invention relates to electric head lamps adapted for various uses, but particularly adapted for use by surgeons and dentists, although it is capable of many other uses.

A lamp constructed in accordance with my invention may be used to great advantage by automobilists and repair men, and by any person who finds it necessary to work in the dark and desires a light which may be easily and readily directed to the point or on the object upon which he is working.

One of the main objects of the invention is to provide a lamp holder which is adapted to receive an ordinary electric pocket flashlight now so universally used, and to provide said holder with means for securing it to the head of the user.

Another object of the invention is to provide a holder adapted to receive a self-conlight rays.

tained electric lamp, said holder bein provided with means to direct the rays of light forward and in the line of vision of the user.

Another object of the invention is to provide a holder consisting of a plate and means for holding an ordinary pocket flash-light thereon, and a light deflecting means by which the light from the lamp ,,will be diverted and directed in the line of vision, means being provided for retaining the said plate in the desired position on the head of the wearer.

There are'many other important objects and advantages of the invention which will appear hereinafter.

In the drawing, Figure 1 is a view showing the head lamp in position for use; Fig. 2 a front elevation of the holder plate; Fig. 3 a vertical sectional viewthereof; Fig. 4; a horizontal sectional view on the line IVIV of Fig. 2; Fig. 5' a side elevation of I the holder plate with the lamp in position thereon; and Fig. 6 a vertical sectional view showing a modified means for diverting the 7 Referring to the various parts numerals, 1 designates the holder plate, which is adapted to be arranged in a vertical position upon the forehead of the user, and which is provided with three slots near each vertical edge thereof, said slots being numbered 2, 3 and 4, and 5, 6 and 7. The head band Patented Oct. 17, 1916.

8 is threaded through these. slots and forms a central loop 9 on the face of the supporting plate, said loop extending between the

slots

2 and 5. After passing the ends of the head band inwardly through the

slots

2 and 5 they are passed outwardly through the slots 3 and 6, and then again passed in- Wal'dly through the slots 4 and 7. Any suitable means, such as a buckle, 10 may be provided for adjusting the head band to the head of the wearer. The loop '9 forms a convenient means for holding the flash lamp 11, said lamp extending downwardly through said loop, as shown clearly in Figs. 1 and 5. By passing the head band through the slots as described, sufficient friction is obtained to hold said band in proper position to retain the flash lamp in position. The

the forward face of the supporting plate.

It will, of course, be understood that the loop 9 will adjust itself to any, shape of lamp and will securely hold, not only the flat lamps such as that shown in the drawing, but also the round or pencil lamps. These pocket flash-lights are self-contained lamps in that the lighting current is ob tained from small batteries placed within them. a

At the lower end of 'the holding plate is arranged a means for reflecting the light rays and throwing them forwardin the line of vision of the user of the lamp. This means, as shown in the drawing, consists of a triangular shell 12, having the top horizont'al plate 13 apertured at 14, through which aperture the rays from the lamp project. The forward vertical face 15 ofthe shell is open, and the bottom 16 thereof inclines from the lower edge of said for in Fig. 6 a prism 18 is shownfsaid prism stood that any suitable means may be ,employed for reflecting, deflecting or diverting the light rays and throwing them forward in the line of vision of the user of the device.

The aperture in the top plate of the shell is preferably circular in order to receive the circular bulb of the electric light carried by the casing. Extending downwardly from the-lower edge of the supporting plate, at

each side of the shell containing the reflector device, is a shield or guard 19. These shields extend below the upper surface of the shell on each side thereof and prevent light rays passing to the rear of the holder .plate,,and serve as means for bridging the space between the top plate of the shell and the bottom plate of the lamp casing. These guards or shells prevent any light passing back to the eyes of the user, and render it unnecessary to have a light-tight joint between the lamp casing the deflector shell.

The head band, as shown in Figs. 2 and 4c,

and the top plate of :serves as the means for securing the fiashlight lamp on theholder plate, but it will, of

course, be understood that any suitable means may be used for this purpose.

What, I claim is: l. A head lamp holder comprising a thin,

substantially flat holder plate, means for attaching said holder plate, in a vertical position flat against the head of the user, means atthe lower end of said plate to divert the light rays and project them forwardly in the line of vision of the user, and means for attaching a lamp in a vertical position flat against the forward side of the holder plate to throw its light rays downwardly into the means for diverting tion to throw its light rays into the means for diverting them.

I 3. A lamp holder comprising a holder plate, an adjustable head band connected to said plate, means carried by the plate at .its lower end to divert the light rays and project them forwardly in the line of vision of the user, and means whereby the head band forms an attaching means for securing a lamp to the holder plate.

4:. A lamp holder comprising a holder plate formed with a series of vertical slots therein, an adjustable head band threaded through said slotsand forming a loop on the forward side of said plate said loo p serving occupying practically the" whole of the interior of the shell. It will, of course,'be under-'" as a lamp holding means, and means-carried by the plate to divert the light rays and project them forwardly in the line of vision of the user.
