s e S s e n WT wli l lfim JOSEPH P. MACHOVEC, OF IOWA CITY, IOWA.

BAND-LIGHT.

Application filed March 25, 1915.

To all whom it may concern.

Be it known that I, Josnrn P. Macnovnc, a citizen of the United States. residing at Iowa City, in the county of Johnson and State of Iowa, have invented a new and use ful Band-liight, of which the following is a specification.

The present in vention appertains to illuminating devices. and aims to provide a novel and improved illuminating device embodying an electric lamp and a battery or suitable source of electrical energy, the device being of such construction as to he applicable to a music sheet, book, rack or the like, for illuminating the same, whereby the musician may readily follow the music.

It is the object of this invention to provide an illuminating device which is light, simple, compact and inexpensive in construction, which is portable and which is app]ica ble to the music sheet for lighting the same.

A notable feature of the invention resides in the fact that the same provides simple and etlicient means for illuminating the music sheet and which may be carried by the music sheet to light the same, the present device eliminating the use of ordinary torches or equivalent illuminating devices now commonly employed which are objectionable for well known reasons.

A further object of the invention is the provision of an electrical illuminating device, which may be taken apart or separated in order that it may be compactly stored within a suitable case or ctmtaincr. when not in use, and whereby when the parts are. assembled the circuit through the battery and lamp Will be established.

It is also within the scope of the invention to improve the device generally in its construction and details, to enhance the utility thereof, and to render the same practical and efiicient in use.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embdoiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure l is a plan view of the improved Specification of Letters Patent.

illuminating device. Fig. 2 is a side elevation thereof. Fig. 3 is a rear view, and Fig.

4 is a sectional view taken on the line -l-l of Fig. 2.

In carrying out the invention. there is provided a battery holder 1, preferably constructed of sheet metal, and embodying the back 2 having the lower rearward] y project ing flange 3 forming the bottom of the holder, and the flange 3 is provided with an upstanding spring tongue 4 adapted to spring to and from the back 2. The side edges of the back 2 are provided. adjacent the upper end of the back with rearw.-|rdly projecting curved spring fingers 5 which project toward the upper or free end of the tongue 4.

The holder 1 is adapted to receive an ordinary flat dry battery 6, the battery 6 being adapted to be slipped downwardly into the holder between the back and tongue -t thereof and onto the flange or bottom 3. The battery (3 is held against the back 2 by the tongue 4, and is held between the spring fingers 5. It is evident that the battery may be readily applied to and removed from the holder, and that the battery may be replaced when it becomes dead. The battery 6 is provided at its upper end with the spring terminals 7 and 8 in the form of leaf springs or resilient tongues.

In order that the holder 1 can be readily applied to the music sheet, book, rack or other object, the upper end of the back 2 is provided with a reflexed forward clip 9,

which projects downwardly, and which is adapted to engage over the upper edge of the music sheet or object 10 so as to overlap the front of the same, while the back 2 of the holder 1 is held against the back of the sheet or article 10. In this manner, the holder 1 may be readily slipped into and out of engagement with the music sheet or support 10.

A pair of upright side wires 11 are carried by the holder 1, the side edges of the back 2 having portions 12 curled or bent around the wires 11 to secure the wires to the holder 1, whereby the wires 11 not only reinforce the holder, but serve as means for supporting the reflector from the battery holder. The wires 11 project upwardly from the holder 1 for the engagement of the reflector.

The reflector 13, which is preferably constructed of sheet metal, and which has its bottom polished or otherwise provided with a reflecting surface, is arched or of arcuate cross section, and is disposed transversely. The rear edge of the reflector 13 has an upstanding portion 14 whose side edges are curled or bent to provide tubular portions 15 arranged vertically and adapted to be slipped over the upper protruding ends of the wires or standards 11, in order to apply the reflector to the battery holder. It is evident at this point, that the reflector and battery holder may be readily detached and assembled, they being provided with a slip joint to this end.

The crest portion of the reflector 13 is provided with an upright sleeve 16 containing the lamp socket 17 into which the plug 18 of the incandescent electric lamp 19 is threaded from below, so that the lamp 19 is disposed within the reflector 13. The reflector 13 projects forwardly so as to overhang the music sheet 10 and the light will therefore be thrown downwardly against the front side of the music sheet for properly illuminating the same.

A central contact member 20 is engaged through the upper end of the lamp socket 17, an insulator 21 being disposed between the contact 20 and socket 17, whereby when the plug 18 is threaded into the socket 17 and bears against the contact 20, the socket 17 and the contact 20 will be in circuit with the lamp, in the ordinary manner.

A radially projecting arm 22 is secured to the upper end of the socket 17 above the sleeve 16. and a radially projecting arm 23 is secured to the contact 20 above the insulator 21, the insulator 21 separating the

arms

22 and 23.

The arm which is a conductor of electrical energy. is connected by means of a coiled or flexible conductor or wire 24 with a binding post 25 engaged to a rearwardly projecting support 26 carried by the portion 14 of the reflector. and the binding post 25 is provided with a depending contact member or pin 27 adapted to bear upon the terminal 7 of the battery 6 when the reflector is slipped downwardly into engagement with the battery holder.

A lever switch or contact member 28 is fulcrumed to the support 26, and its upper end or arm is connected by means of a link 29 to the arm 22 of the lamp socket 17, the lower end or arm of theswiteh 28 being arranged to overlap or engage the terminal 8 of the battery when the reflector and battery holder are assembled. As a convenient means for opening and closing the circuit. the arm 22 is preferablymounted for oscillation, the socket 17 oscillating therewith. and the arm 22 in being oscillated will oscillate the lever switch 28 to swing the same into and out of engagement with the terminal 8 of the battery, and which will close and open the circuit, respectively, 51 will be obvious. lt is to be uuderstmal however, that 'the circuit may be opened and closed in any other equivalent manner, or by slipping the reflector and bolder apart or together, so as to bring one or both of the battery terminals out of engagement from its contact member when it is desired to extinguish the lamp. The portion 11 of the reflector and sleeve ll) are preferably connected by means of a web or brace 30, which also serves to brace the reflector 13.

In use, when the reflector and copy holder are slipped into engagement with one another, it being supposed that the battery (3 is held within the holder 1. the contact incinber 27 and switch or contact member 28 of the reflector will be moved into engagement with the respective terminals 7 and 8 of the battery, which will close the circuit through the lamp, as will be obvious, whereby the lamp 19 will be lighted, and by applying the holder 1 to the music sheet or object 10 to be lighted, the light will be thrown upon the front side thereof. The circuit may be readily opened, when it is desired to extinguish the lamp, thisbeing accomplished by opening the switch, which in the present case may be swung open or away from the battery terminal 8. By returning the switch to closed position, the lamp will again be lighted, and in this manner the lamp may be lighted while the piece is being played and may be extinguished between the playing of the various selections.

The present device is adapted especially for use by bands and musicians, when playing at night time, and each musician may be provided with one of the present lights, so that he can readily follow the notes. The present device therefore eliminates the use of torches and similar objectionable illuininating means now employed. Vhen the device is not in use, the reflector and battery holder may be detached, so that they can be compactly assembled and stored within a case or container for that purpose, or they may be compactly carried or stored with the musical instrument, if desired.

Having thus described the invention, what is claimed as new is 1. In a device of the character described, a battery holder having upstanding portions, a reflector having a portion at its rear edge slipped upon said upstanding portions, a lamp carried by the reflector, and a pair of downwardly projecting contacts carried by said portion of the reflector and connected to the lamp, said contacts being adapted to engage the terminals of a battery held by the holder when the reflector and holder are assembled.
