7 new WAL E IOLLACK, or RICHMOND HILL, YORK MULTIPLE DISPLAY LAMP Application filed April 1,

This invention relates to new and useful improvements in a lamp.

Theinvention has for an object the construction of a deviceof the class mentioned which is characterized by a hollow casing having a tubular-portion at the top, a lamp adjustably supported depending from said tubular portion,-and a plurality of tubes 'ra- 'dially arranged upon said casing relative to said'la'mp when the lamp isin a loweredjposition.

Theinvention has for'a still further object the arrangement of a large opening, in 5 said casing normally closed with a cover to allow access to said lamp. 3

Furthermore, the invention proposes the v provision of a' plurality of covers upon the extended ends of said tubes in the formof mirrors which may be'opened to refle'cttransmita ted light. 5 c A still further object of this invention is the provision of a universal joint for holding said display lamp in various tilted positions. Furthermore, the invention proposes an arrangementwhereby said tubes are adjustable, and the provision of means for holdingv the tubes against extension or retraction when said lamp is in its operative position.

The invention has for another object the construction of a device of the class described which is of simple durable construction dependable in use and eflicient in operation and which can be manufactured and sold at a reasonable cost. r s

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description. and accompanying drawings, and

to the appended claims in which the various novel features of the invention are'more particularly set forth. v In the accompanying drawing forming a 5 material part of this disclosure 1 Fig. 1 is a perspective view of a device constructed according to this invention.

Fig. l1 is a similar 11-11 of Fig. 9.

r The multiple electric ing to this invention, comprises a hollow casing 10 having a tubular portion 1 1 at the top.

A plurality of apertures 13 are formed in the; tubular portion 11 to allow the escape .of heated air from Within thedevice. A cover 7 element 14 is mounted uponthe top of the tu-- bular portion 11 and connects with a universal member15which in turn is connected with a plate 16 for attachment upon the ceil ing. At diametrically opposite sides the tuview taken on the line bular member 11 is formedwithslots 17, A

bracket 18 is located within the casingand is provided with projecting studs 19 which pass throughthe slots 17 Nuts 20thr'eadedly engage .uponthese studs and serve. to hold positions 7 the bracket 18 in various elevated vwithin the tubular member.

A lamp socket 21 is attached upon the bottom of the bracket 18 and supports a lamp 22. L The lead 23 from the lamp extends'through the universal 15 and through the ceiling bracket 16, not shown on the drawings, but as is customary. in ceiling fixtures. ,A' portion of the line 23is loose so that the bracket 18 will be raised. A plurality of tubes with lenses 24 radially pro ect from, the casing 10 relative to'the center of the lamp 22 when the latter is in a lowered-position; A cover 24 closes the outer ends of each'of the tubes 24.

This cover is constructed with amirror26-on1 Fig. 8 is a view similar toFig. 7 but show- 60 display lamp, accord- 7 0 its inner side so as to be capable of reflecting light passing through the tube. More par 1' .ticularly, the cover is provided with a standard portion 27 slidably arranged upon an arm 28 hingedly mounted at 29 upon a band 30 clamped at 31 uponthe end of the tube. The arm 28 hasa projection 32 atits free end to limit the sliding of the cover 25. A set screw 33 holds the cover 25 in various adjusted positions oirtlie arm. The hinge of the lever 28 maintains any set positionsdue to frictional contact.

Each of the tubes 24 is slidably "arranged through an opening 35 formedin the hollow. 5 casing.

Resilient means is mounted within the casing for holdingthe tube in variousprojected positions. More particularly,rim 36 is secured upon the inside of the'casing wall and support springs 37 which particularly encir cle the tube24. "The springs 37 are made integral with rim 36 which "is bent downwardly to form recesses 37 on which the tubes 24 may rest and will grip the said tubes with rections and shaped to rest and tension the upper periphery oftubes 2 L.v A plurality or peripheral ridges 88 are formed upon the tubes against which'the. springs 37 hold the tubes in various projected positions. Catch fingers 39 project from the bracket 18 and .haveat their free ends teeth 40 engaging against the tubes 24: sons to latch the tubes lowered position. 'In Fig.7 a'modification of the invention has been disclosed in which a casing 10" has been illustratedcwhich is substantially elliptical in transverse cross sections. From this casing a plurality of tubes 24 project. These tubes are arranged in one horizontal plane I through the center ofthe casing. In the casing shown in the previous figures the tubes project atdifierent inclinations and form di ferent planes. In other respects this form of the I invention is identical to the previous form. V

ljigs 8 and 9 disclose another variation whichis substantially identical with Fig. 7

. L59 but distinguishes in that a casing 10 is provided whlch has an open bottom 42. In other respects it is identical to the previous construction. While only a few designs of casing have been shown it must be borne in mind that the invention'intends to cover all types ofpcasingssuch as cubical, spherical, cylindrical oval, triangular, oblong. etc. d

When it is desired to concentrate the light through the bottom opening 42,2111 the mirrors 26 are closed and the reflector 10D reflects a flood light through the bottom opening 42.

A plurality of apertures 43 are provided at the top of the casing 10G toallow the cs "(15 cape of heated air-from within the device. I

the aid of the spaced springs 37 i which are bent upwardly projecting from opposite diagainst'motion when the bracket 18 is in a While we have shown and described the preferred embodiment of ourinvention, it is to be understood that we do not limit ourselves to the precise construction herein disclosed and the right is reserved toall changes and modifications coming withinthe scope of the invention as defined in the appended claims.
