application filed March 7, 1915. Serial No. 2203M.

To all whom it may concern:

Be it known that we, Francis M. RosnN- FELD, a citizen of the United States. and a resident of the-city, county, and State of New York, and Louis E. SHAW, a citizen of the United States, and a resident of East.

Orange, Essex county, New Jersey, have invented an Improvement in Electric Lamps, of which the following is a'specification.

ur invention relates to electric lamps. of

a character peculiarly adapted to being in part disassembled for the purpose of com pact packing, but our improvements are not limited to this type of lamp and may be applied to many other ttypes of electric lamps without substantial change. The drawings accompanying this specification, however, illustrate a type of lamp which might be termed atraveling lamp, wherein the variousparts of the lamp may be packed into the lamp housing, thus making a conzeaient and compact structure for transportation. It should be understood, however, that these drawings are illustrative merely of one form that our invention may take and are not intended to show the only form in which our invention may be embodied.

In the drawings,

Figure l is a front view of our improved lamp in an assembled condition;

Fig. 2 is a vertical, sectional view thereof;

Fig. 3 is a side view of the base ofour improved lamp, the base being that used in the embodiment illustrated/in Fig. 2;

Fig.4 is a plan view of the base shown in Figs. 2 and 3;

Fig. 5 is a side View of the base shown in Figs. 2, 3 and 4, showing the base being used to attach the lamp to a table or other suitable support;

Fig. 6 is a sectional view of a modified form of the base and standard;

Fig. 7 i a plan view thereof; and

Fig. 8 is a side view of the base illus tratedv in Figs. 6 and 7, showing the means for attaching said base to a table or other suitable support.

In the drawings, 1 illustrates a housing,

or of any other suit which may be tubular, able shape, that illustrated being tubular. It is preferably made,of brass or other suitable material and having an aperture 2 extending substantially the entire length of desired, and carries at as for instance, a pull iswptch operated by v the chain 7. A flexible corc 8 provided with a suitable connecting plug is also attached to the socket 5. Both the switch operating means 7 and the flexible cord 8. are brought out from the lamp through the aperture A cover 9 is hingedly mounted upon the tubular lamp housing 1. We prefer to mount the cover 9 by rolling a wire 10 in the upper edge of the cover and holding the wire 10 in place by means of spring wire loops 11 at each end of the cover. 9-. Loops 11 pass from the inside of the housing 1, housing again,

over the wire 10 and into the and may be conveniently located within beads 12 at each end of the housing. Beads 12 serve to stiffen the housing and also afford a recess for loops 11, so as to present a substantially fiat surface on the interior of the housing. The tension of the loops 11 is sufficient to hold the upper edge of the cover Cap 3 may be made re-.

switching mechanism,

socket 5, within which 9 in contact with the case and to thus produce suiiicient friction to hold the cover 9 in any desired position. The cover 9 may thus be used for a shade, as well as a closure for the opening 2. 1

Mounted within'the housing 1 is a housing supporting means, which may consist of a bracket 13, having a screw ferrule 14 attached thereto by means of a hinge 15. The parts are so proportioned that by swinging the ferrule about thehinge 15, it may be either extended through the aperture, as shown in Figs. 1 and 2, pr folded into the body of the lamp housing 1.

The lamp housing is supported by means of a standard 16, which is screwed into furrule 1 1 and. may be easily removed therefrom, Standard 16 is screwed into one of the base members 17 which in the embodiment illustrated in Fig. 2 consistsof a yoke having a flat foot 18. The base also comprises another base member 19, which is attached to a plunger 20, slidablymounted within the standard 16. The foot or base member 19 is arranged with a raised portion 21, and being pivotally and slidably mounted within the standard 16 may be. rotated from a position in alinement with the other foot or base member 18. to a position at right angles thereto. and locked in such an gular position. This locking in angular position isfacilitated by the engagement of the central portion of foot member 18 with the indentedportion 21 of foot member 19.

The

foot members

18 and 19 are normally held together by means of a spring 22, preferably located within the standard 16. Spring 22 acts against the closed end 23 of the standard 16, or against some other suitable abutment, and against the movable spring abutment 2''}, which bears against the top of the plunger 20. The length of the plunger 20 is preferably not greater than the diameter of the lamp housing 1, for the purpose of packing the various parts of the lamp, as will be hereinafter explained.

If it is desired to clamp the lamp to a. table or other suitable support, the. base members are separated against the pressure. of the spring 22, and the support inserted between them. It will be noted that because of the raised portion 21 .in the footer base member 19, it is easily possible toattach the lamp upon a rounded surface.

When it is desired to pack the lamp, the bulb. 6 is first removed, the standard '16 is then unscrewed from the ferrule, 14 and the ferrule 14 is folded about the hinge 15 until it comes within the lamp housing 1. Standard 16 is then unscrewed from the base member 17, the removable abutment 24 being prevented from leaving the standard, by means of the turned-in end 25, or other suitable stop. Standard 16 is preferably of a length slightly shorter than the length of the tubular housing and may therefore be easily inserted therein. Foot or

base members

18 and 19 are then swung around, so that they come into alinement, and the. total height of plun-.

ger 20 and the base members being less than the diameter of the tubular housing. and the length of the base members being less than the length of the tubular housing, the two base members and plunger 20- may be inserted into the housing. The switch operating chain 7 and the flexible cord 8 are then put into the housing through the aperture. 2. and cover 9 is closed, thus closing housing 1, which then containsall of the parts of the lamp.

Figs. 6,7 and s SllOW a modified form of base, which maybe used with the lamp housing and other parts illustrated in Figs. '1 and 2, or with other suitable parts. In this construction, a tension spring 26 is used instead of the compression spring 22, and the yoke 17 is omitted. As in the embodiment previously described, the standard 16 is tubular. but the plunger 20 is also tubular and of greater length than that shown in the embodiment illustrated in Fig. 2. Standard 16 in the modification illustrated in Figs. 6, 7 and 8 is detachably screwed into foot member 27, and plunger 20 is detachably screwed into foot member 28. Spring 26 is attached at one end to the standard 16, as at 29. and at its opposite end to plunger 20, as at 30.

It will thus be seen that the foot or base members 28 may be turned into alinement with one another, as in the modification previously described and that they may be turned to a position at an angle to one another and locked in such position, b means of the engagement of the raised portion 31 of base member 27 with base member 28.

When it is desired to disassemble the standard and base structure of the modifica tion shown in Figs. 6, 7 and 8, foot, member 28 is unscrewed fromplunger 20 and foot member 27 is unscrewed from standard 16. The motion of plunger 20 in standard 16 may be limited by means of a. pin 32, or other suitable stop.

If it is desired to attach the lamp to-a table or other support, the foot members are separated against the tension of spring 26 and clamped over the support. In Fig. 8. we have shown a lamp attached to a round supporting member 33, and in order to firmly attach the. lamp to rounded supporting members, it is desirable to form foot member 27 with a'cnrved portion 34. If it is desired to attach the lamp to the modification shown in Figs. 6, 7 and 8 to a surface having paralin the same manner as with the lamp shown in the cn'ibodiment of Figs. and 2.

As in. the, embodiment previously described, the. standard 16 is slightly less than the. total length of the housing,and the footmembers 27 and 28 are also slightly less than such length. They may therefore be inserted in the housing and the lamp packed in the same manner as in the embodiment previously described.-

We do not desire to limit ourselves to the particular embodiments illustrated and described, since it is evident that many changes may be madewitihout departing from the spirit of our invention.
