Filed Jan. 3, 1961, Ser. No. 89,145 2 Claims. (Cl. Mil-6.4)

This invention relates to lighting attachments in general, and is particularly directed to a lighting attachment that is arranged for securance to a conventional clip board or the like in order that the face thereof may be illuminated for nighttime service.

Clip boards are utilized in a variety of applications, many of which entail viewing the board or writing thereon in dark surroundings. Law enforcement oflicers such as policemen, fish and game Wardens etc., firemen, military personnel, oil company employees, and the like are but a few who have occasion to utilize clip boards in the dark during the normal course of their work. Although attempts have been made to incorporate lighting means with clip boards, these attempts have been variously disadvantageous in that the lighting fixtures have required special construction of the clip and accordingly could not be employed with existing clip boards. Moreover, prior lighting fixtures have not facilitated adequate illumination of the bottom of the board and have been susceptible to premature rusting of the components. By virtue of the inadequacies of the prior art, clip boards having directly associated lighting fixtures have not found widespread use and it has been the usual practice to utilize a flash light to illuminate the clip board, no matter how cumbersome and difl'icult the manipulation.

Advantages are therefore to be gained by the provision of a lighting attachment which may be directly employed with existing clip boards of conventional types and which does not possess the disadvantages of previous clip board lighting fixtures mentioned hereinbefore.

It is therefore an object of the present invention to provide an improved lighting attachment for use with a clip board or the like to facilitate illumination of the entire face thereof.

An ex remely important object of the invention is to provide a lighting attachment that may be readily employed with all classes of existing clip boards without requirement of extensive modification.

Another object of the invention is the provision of a lighting attachment of the class described which when mounted upon a clip board functions as hanger means whereby the board may be readily suspended from the arm of a user during periods of disuse, thus leaving both hands free for other purposes.

Yet another object of the invention is to provide a clip board lighting attachment of the class described that is arranged to permit the free circulation of air about the batteries and other components in order to minimize swelling of the former and rusting of the latter.

It is a further object of the invention to provide a clip board lighting attachment of the class described which. includes a detachable hood member to permit ready access to the battery compartment thereof, the hood member being uniquely releasably secured to the remainder of the attachment without requirement of threaded fasteners.

It is still another object of the present invention to provide a clip board lighting attachment of the class described in which the battery mounting bracket may be selectively adjustable in order to maintain the bracket in a close fitting relationship with the hood and the batteries.

Yet another object of the present invention is to provide a clip board lighting attachment in which the components thereof are so arranged as to facilitate illumination of a work sheet on the clip board even though several top sheets may be interposed between the source of light and the work sheet.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forth in the claims.

FIGURE 1 is a plan view of the lighting attachment as mounted upon a clip board with portions of the hood and battery mounting bracket of the attachment broken away.

FIGURE 2 is a front elevational view of the embodiment of FIGURE 1 with portions of the hood, battery mounting bracket, and battery broken away.

FIGURE 3 is a sectional view taken at line 3-3 of FIGURE 2.

Referring now to the drawing, there is shown a conventional clip board 11, including a rigid rectangular base 1.2 at one end of which is attached a spring clip 13 for releasably fastening papers to the base. The clip board of course provides a portable firm backing surface for the papers such that they may be readily written or drawn upon in the field. Although under daylight or other well lighted conditions the board may be grasped with one hand and the writing implement in the other, such is not the case at night or in poorly illuminated surroundings where the face of the board is not clearly visible. More specifically, although clip boards have been heretofore variously provided with integral lighting means, em'sting clip boards could not be so adapted and accordingly it is the usual practice to illuminate existing boards by means of a flash light where the board is utilized in the dark. This practice necessitates placing the board on the ground or other solid surface inasmuch as the users hands are both occupied in holding the flashlight and writing implement.

I have overcome the foregoing difficulties by providing a lighting attachment 14 which may be readily mounted in the manner depicted in the drawing upon the base 12 of the clip board 11 or any other variety of existing clip board. Moreover, unlike previous lighting fixtures provided integrally with a clip board, the attachment 14 is arranged to fully illuminate the entire face of the base 12, even the lower end thereof. Also, when several sheets of paper are being used on a clip board, it has been found that due to the particular arrangement of the fixture that two or three such sheets may be turned back so as to be nterposed between the light source and the sheet being used without materidly diminishing the amount of illumination on such lower sheet. To these ends, the attachment 14 in general includes a resilient metallic battery mounting bracket 16 having a reflector 17 formed integrally therewith, the bracket having flanged vertical legs 18, 19 depending from its opposite ends for mounting the bracket upon the board in overlying straddling relationship to the clip 13. More particularly, the legs are of sutficient height that when they are secured as by means of bolts 21 to the base 12 on opposite sides of the operating handle portion 22 of the clip, the bottom portion of the bracket clears the handle by an amount suflicient to permit unimpeded operation of the clip. With the bracket mounted in such an elevated position relative to the face of the base 12, moreover, the reflector may be inclined from the horizontal to direct light from a flash light bulb 23 or the like, mounted upon the reflector, over the entire face of the board.

As regards the preferred structure of the bracket 16 and integral reflector 17, it is to be noted that the bracket is preferably provided with a flat horizontal elongated base portion 24 having an upstanding rear wall portion held between the top and base portions of the bracket.

The forward edge of the base portion 24 terminates in an upwardly and forwardly inclined projecting portion 29 that terminates at its upper edge in a horizontal plane that is tangent to the arcuate top portion 27. The inclined projecting portion 29 is chromed at its outer surface, or otherwise rendered reflective to light, so as to provide the integral reflector '17 of previous mention.

As regards the mounting of the flashlight bulb 23 on the reflector, it is to be noted that a conventional internally threaded light bulb socket 31 extends through the projecting inclinedportion 29, preferably at its center, in right angular relation thereto. The open end of the socket 31 projects beyond the reflecting surface of the inclined portion such that when the bulb is within the socket, the bulb envelope is spaced forwardly from the reflector. As much radiated light from the bulb as possible is then reflected from the reflector upon the base of the clip board.

An on-oif switch 32 is additionally carried upon the inclined portion 29 of the bracket for purposes of selectively connecting the light bulb 23 to the batteries 28. The switch is mounted to one side of the socket 31 with its operating toggle 33 extending through a slot 34 in the inclined portion 29 and projecting forwardly thereof so as to be readily accessible from the front of the lighting attachment The terminal lugs of the switch are disposed rearwardly of the inclined portion 29 in close proximity to the terminals of socket 31 as well as the batteries 28 such that connection of the lighting circuit may be accomplished with a minimum expenditure of lead wire. More'particularly, as regards the circuit, it is to benoted that a lead wire 36 connects one terminal of the switch to one terminal of the socket, the other socket terminal being directly grounded to the inclined portion of the bracket. Another lead wire 37 connects .the other terminal of the switch to a battery contact 38 insulatedly' mounted upon a stop strip 39'secured between the base portion 24 and top portion 27 of the bracket at one end thereof. The contact is disposed to engage the center terminal of one of thebatteries 28 when they are fully inserted into the bracket. The circuit is then completed by means of a removable metallic hood 41 that encloses the open regions defined between the respective portions of the bracket and'is in electrical contact therewith as well aswith thebase of the other battery through another battery contact :40 secured to the hood. The bulb, switch, and batteries are thus in a series, circuit which 7 is ground returned through the bracket and hood.

It is of importance to notethe manner in which the hood 41 is removably secured to the bracket without the employment of threaded fasteners. More particularly, the hood includes a flat top portion 42, vertical back portion 43, arcuate interconnecting portion 44,-between the. top and back portions, and depending side portions 46, 47. The back and arcuate portions of the hood are.

engageablewith the back and arcuate top portions of the bracket with the topportion of the'hood bridging the intervening space between the top portion of thebracket and upper. edge of the inclined portion thereof; The top portion of the hood is provided with a downwardly turned rim 48 alongitsforward edge for engaging the inclined reflector portion 29-of the bracket adjacent its upper,'

edge. Inaddition, the back portion of the hood is provided with a pair of forwardly projecting detents 49 that.

are engageable with a pair of apertures 51 in the back portion of the bracket. Itwill thus be appreciated that the rim 48 maybe engaged upon the edge of theinclined rearward pressure forces the resilient reflector portion 29 sufliciently rearward to facilitate disengagement of the detents from the apertures whereby the hood is freed for direct upward removal from the'bracket.

As a further important feature of the present lighting attachment, the resilient nature of the battery mounting bracket permits ready adjustment of the reflector 17 and the arcuate top portion 27 so as to selectively vary the degree of clamping engagement of the hood and batteries with the bracket.

There is thus provided by the present invention a lighting attachment that may readily be employed with any existing clip board or the like to fully illuminate same for service in dark surroundings. By virtue of the unobstructed space between the batteries and other electrical defined by the base of the board, the bracket proper, and.

the bracket legs. 7
