Patented Mar. 1, 1932 HORACE P. ADAMS, F ST. PAUL, MINNESOTA PORTABLE FLOODLIGHT Application led December 14, 1929. Serial No. 414,143.

My invention relates to a portable iiood light device particularly adaptable for use at playgrounds, parks, in public buildings.

and like places, and the object is to provide a simple, substantial and efiicient lighting device of said kind involving several features hereinafter fully set forth, reference being had to the accompanying drawings, in which,-

Fig. 1 is a side elevation of my improved device mounted on a fixed post for overhead lighting purposes.

Fig. 2 is a side elevation of the device mounted on a portable pedestal or stand.

Fig. 3 is a side elevation of the lighting device with a modified cover and Fig. 4 is a` face view of Fig. 3 showing two transparent or translucent plates partially withdrawn from the cover.

Fig. 5 is a cross sectional enlarged detail of the closed type of cover and Fig. 6 is simi lar sectional view of a slide receiving type of cover, both these figures being taken on a plane represented by the line A-A in Fig. 4.

Fig. 7 is a view in small scale of the flood light hung from an overhead cable andv adapted to be moved thereon.

Fig. 8 is a side elevation of the device resting on the ground or floor, as used for footlight purposes.

Referring to the drawings by reference numerals, lO is a fixed post with a fixed hori- Zontal arm 11. 12 is a metal bracket in vertical plane suitably fixed to post 11, under its arm said bracket bored for a clamp-bolt 13, having a thumb-screw 13S with which to clamp an ear 14E to the bracket 12, said ear being also bored for the bolt 13. The saidl ear 14E is fixed to back of a metal housing 14, having suitable fixed sockets for one or more electric bulbs 15.

From the front part of housing 14 extend four adjoining iiared panels 14?, all pref` erably having highly polished interior surfaces as has also the inner walls of housing 14 to provide bright flood light projected from the opening of the device, said opening being of course quadrangular or preferably being so made. 16 is an electric cable in circuit to provide current for the bulbs.

In Fig. 1 is best shown a bore 17 in ear 14 between the bore for the bolt 13 and the back of housing 14, thisvproviding to be slipped slidably on an upright bar 18 of a portable pedestal 181) on a base 18B and the entire lighting device may be held at any elevation on said bar 18 by suitable means such as an adjustable collar 19, the light being thus supported but free to be swung horizontally to any position desired.

One of the long edges of a panel 14 is provided with piano-type or equivalent hinge means 2O (see topV of light-device in Fig. 1 and topy part of Figs. 4 and 21 are correresponding hinge means on either of two 5 types of reiiector covers and 22 is a removable hinge pin adapted to be inserted through members -20-21 providing a continuous hinge. One type of cover as 24 in Figs. 1 and 5 is plain, being made of heavy sheet metal, suspended from the hinge means described and normally closing the device, its

`lower edge being frictionally held in place by a yieldable shoulder spring 23 fixed to the outside of the lower panel (see Figs. 1 andv i' 2), the shoulder of same engaging the cover edge. f

Vhen the flood light is mounted horizontally as in Fig. 1l the solid type cover ynor-.-

mally closes the device but said cover may be raised when light is desired by means of a flexible cable 25 attached to the lower part of the cover as at 26, extending thence to a pulley 27' on arm 11, thence over another pulley 27A on post 10 and down the side of the post and fixed to a long flat bar 28 guided vertically in a fixed guide 29 on the post. This bar has its lower end within reach from the ground 30 and may have a slot 31 to engage over one or more fixed staples 32 in the post, a padlock 33 or like means to lock the bar in lowered or raised position. Pulling the bar down causes cable 25 to open the cover of the light device to a desired angle and the inner .j surface of said cover may also be highly polished or glossy to deiiect light downwardly from the device. The lid or cover drops back to closed spring-held position when bar 28 is released and moved upwardly and said lid protects the interior of the light and the bulbs from damage by vandals or weather conditions.

24A is a cover of the same size as cover 24e and has hinge means 21 such that this cover can replace cover 24 when so desired. This cover 24A however is merely a quadrangular frame with parallel inwardly opening grooves QLG opening sidewise from the frame so that translucent colored panes 39 or transparent panes may be slipped into and slidably retained by said grooves as desired, the object being to provide means for projecting clear or selectively colored light. This is very desirable for throwing suitably colored liood light on various objects, performers, etc.

In Fig. 7 the device is shown suspended from a cable 35 passed through an aperture of the ear r14E and the device being movable along the cable by means of secondary cables 36B and SGL connected as to eye-bolts 37 on the housing 14 and extending from the device to the right and left, respectively and parallel to cable 85.

In Fig. 8 the device is shown resting on the ground to serve as Hood light or floor light means projecting light on a parade, a pageant or the like. Y

I have illustrated my device and described same in desirable type of construction but it is obvious that a number of modifications may be made without departing from the scope of the invention. It is clear that with my device mounted as in Fig. 1 and closed by a solid cover it is out of reach and cannot be damaged seriously, its reflector surfaces and bulbs being fully protected. JAdjustment of nut 13S will hold the device also at other angles than that shown but in an overhead mounting it is usually desired to throw light toward the ground over as great an area as possible.

I claim:

In an overhead floodlight of the class described including a flared light projector pivotally mounted on an upright standard and under an arm of the latter; a normally depending cover hinged to the upper part of the opening of said projector and adapted to shut off the light therefrom, said cover pro vided with a suitable shiny surface on the side adjacent said opening, a yieldable friction catch on the lower part of the projector to hold the cover closed, flexible cord means attached to the free edge part of said cover opposite its hinges and extending thence over suitable guide means on the arms of the standard to the standard and downwardly parallel to the standard toward the base thereof, said latter part of the cord means adapted to be manipulated to open the cover to desired angular position relative to the light projector opening for the purpose described.

In testimony whereof I ax my signature.

HORACE P. ADAMS.
