STAGE-FOOTLIGHTS.

Specification of Letters Patent.

Patented June It, 1915..

Application filed May 25, 1914. Serial No. 840,732.

To all whom it may concern:

Be it known that I, ANTON T. KLineL, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Stage-Footlights, of which the following is a full, clear, and exact description.

This invention relates to stage footlights, and its chief object is to provide an improved construction whereby the footlights, when not'in use, can be concealed below the .stage and the space covered by a suitable lid or closure flush with the surface of thestage.

To this and other ends the invention consists in the novel features of construction and combinations of elements hereinafter described.

One form of the invention is illustrated in the annexed drawings, in which Figure 1 is a perspective view of the front of a stage equipped with my invention, showing one section of the foot-lights raised and the other section in depressed position.

Fig. 2 is a plan view, with the footlight sections in depressed or closed position, and showing an arrangement of the sections suitable for a stage with a curved front. Fig. 3 is a detail plan view of the frame of a single section. Fig. 4 is a section on the plane of line 4-4 of Fig. 3, but with the closure or lamp-carrier, the latter being in depressed position. In this figure the box which carries the lamps is indicated diagrammatically in dotted lines. Fig. 5 is a section on the plane of line 4.-4; of Fig. 3, showing the feotlights in raised position, and the trough or conduit below, for the wiring. Fig. 6 is a detail view showing a convenient method of pivoting the lamp-carrier to the supporting brackets. Fig. 7 is a sectional view showing a modified form of supporting bracket for the lamp carrier. Fig. 8 is a detail sectional view showing convenient means for locking the lamp carrier in closed or depressed position.

In accordance with my invention the lamps are supported by carriers 10, mounted in a narrow opening across the front of the stage and pivoted at their ends in such man nor that they can be swung down flush with the stage (the lamps being concealed below the stage) or swung up above the surface of the stage, as clearly shown in Fig. 1, wherein the stage is designated by 11. The carriers a straight line across are pivoted to suitable supports underlying the opening, as hereafter described, but instead of attaching the supports (or brackets) directly-to thestage floor, I prefer to mount them on the underside of narrow rectangular frames, as 12. The footlight outfit, consisting of as many such units as may be required for the given stage, can then be manufactured at a factory and sent to the theater. A suitable opening, or several openings end to end, is then cut in the stage floor and the frames mentioned are fitted therein, the frames lying flush with the surface of the stage and becoming in fact a part of the stage floor. If the front of the stage is straight, the opening or openings to receive the footlight units will usually extend in the stage, but if the front is curved the units may be arranged in a curve also, as indicated in Fig. 2. In such case the ends of the frames 10 will usually be initered, as shown, to permit the units being brought close together, and accordingly I prefer to make the ends of the frames of pieces sufliciently wide to admit of various degrees of mitering. This makes it unnecessary to keep on hand a large stock of units of different sizes, as in most cases units of standard size can be trimmed to fit.

The lamp-sockets 13 are mounted in a shallow box 14 projecting from the lower portion of the carrier 10, which box forms the bottom of the lamp case 15. The rear wall 16 of the lamp case, secured to the can rier 10 and provided with a curved upper portion 16, constitutes the reflector for the lamps, as clearly indicated in Figs. 1 and 5.

The supports or brackets 17 to which the carriers 10 are pivoted at their ends are best shown in Figs. 4 and 5. By preference they bridge, or extend across, the frames 10, and are fastened to the underside thereof. The body portion has its upper edge flush with the underside of the frame 11, to serve as a support for the ends of the carrier 10 when the same is folded down, while the arm 17 extends forwardly and upwardly from the lower part of the body portion. thereby producing a deep recess in which the lower portion of the carrler 10 swings when the carrier is raised to the position shown in Fig. 5. The inclined forward edge 17 ofthe body portion serves as a stop, against which the carrier rests when in raised position. the

end-edges of the carrier being recessed as pivots, that is, toward 'extremefront of the stage,

the edge of the carrier at 18, if necessary, to fit the said inclined edges of the body.

The upper edge of the body portion of each bracket or support 17 is provided, near the inclined edge 17, with a socket 19 to receive the pivots 20 onthe carrier 10. These pivots can be connected to the carrier in any convenient manner, shown a method in which the pivot 20 projects from a small bracket 21 suitably fastened to the carrier. It is evident that'the use of open-topped sockets, as shown at 19, permits the carrier to be lifted out of the frame at any time, thus affording instant access to the wiring below.

The conductors or cables 22 which carry current to and from the lamps are conveniently located in a trough or conduit 23, Fig. 5, immediately below. In most cases, particularly where the stage-structure is built of concrete, this trough is formed in the stage-structure without requiring any change in or addition to the footlight units, but whenever necessary or desirable the trough canbe made a part ofthe footlight units by a simple modification of the brackets which support the lamp carriers. Such a modification is shown at 17, in Fig. 7. If desired, the brackets can be boxed up, with a bottom 23 and sides 23", or they may be left open to afford ready access to the wiring from below the stage.

if the weight of the lamps and lamp-case keeps the center of gravity. in rear of the theback of the stage,

the carrier will swing down to closed position of its own accord, unless a stop of some kind is used to prevent it. Convenient means for the purpose is shown in Fig. 6, the same consisting of a spring 24, fastened to the box 1% and having a nose'25 to engage the ledge 26, the'latter being a suitable strip fastened on the underside of the frame 12 to serve as a support for the edge of the carrier 10. -Pressing the spring inward permits the carrier to swing down.

As footlights are always located at the outside of the curtain, it is not often that carriers 10 will be walked'upon; but since the pressure of i the foot on the rear portion of the carrier might cause the same to swing up, it is best to provide means the carrier closed, as

for example a springpressed bolt 27 Fig.

8, slidably mounted in into the adjacent edge of the frame 11.

-When the ring 28 is raised on its pivot 29 the lug 29, engaging the finger 31 on the bolt, moves the bolt out of the socket in the frame 11 and permits the carrier to be raised. 1; v

It will be observed that when'the lamp carrier 10 is raised. the rearedge (that is, the edge toward the back of the stage) and in Fig. 6 I havepermit spectators in for positively holding side of each carrier. 10 and extending moves up, while-the front edge movesv down, as a consequence of the fact that the pivots on which the carrier swings are located well between the front and rear edges instead of at the front edge. This feature is not indispensable, but it is highly advantageous, as it permits the use of a carrier wide enough to support the lamps in proper position' for illuminating the stage, without making the carrier, when in raised position, project too high above the stage. The practice among present day architects is to keep the footlights as low as possible, so that the stage may be as high as possible and still the first few rows of seats to see over the footlights. In accordance with this practice, the plans and specifications for theater construction call for a height of footlights not exceeding about three and a half inches. Hence the importance of my arrangement, by which a carrier of ample size can be used and still not exceed the height mentioned when in raised position.

It is to be understood that the invention is not limited to the specific structure herein described, but may be embodied in other forms without departure from its proper spirit and scope.

In the appended claims the lamps are referred to as being on the underside of the carrier. By this it is meant that the lamps are on the side which is underneath or below the surface of the stage when the carrier is in depressed or closed position.
