residing at State and useful Im- Packing for Incandescent Lamp Bulbs and the like, of which the l following is a specification.

Various additional advantages obtainable in connection with the'inv comeapparent from the des ention will be cription hereinafter of certain particular forms of packing which embody it,

When tubular. wrappers or jackets of this their corrugations are somewhat flattened, 1

while the ends of the jacket assume the conical-form illustrated in Fig. 3), and some four or five of the lamps thus jacketed are packed side'by side in a card-board carton such as is shown 7 being base upward and the rest tip upward. \Vhile the resulting package is reasonably good, it nevertheless has the disadvantage that in consequence in Fig. 3, alternate lamps of careless packing or of shifting of a lamp in its jacket the tip 1 of a lamp (or the bowl of a tipless. lamp) not infrequently lies against the top or the bottom of the box, where it is exposed to almost, the full impact of any blow that the or that the tip even penetrates the cardboard of the box so as to be broken .off by jar orshock endw'se or sidewise of the box or by one box sliding over another, etc.

According to my invention,

the lamp in an improper position in the packing or of its taking up an improper posit-ion is entirely'obviated by making the packing resist movement of the lamp toward the end of the which the tip end or bowl of the bulb lies,

either yieldin'gly or absolutely. This may be effected by contraction or reduction in any way of the portion of the jacket through which the lamp must move in this. direction, particularly by providlng in this.

which is yielding throughout its length, for

example, by accentuation or reinforcement the container inwhich .it is e move toward the end at which the tip lies.

In the packing shown, the jacket or wrapper 1 as a whole comprises an ordinary--corrugated tubular or-cylindrical sleeve part 2 such as would prior to my invention be used forthe lamp 3 to be packed, and .all the .modes of action mentioned above are present. For a straight sided watt 110. volt v Mazda incandescent lamp whose maximum dlameter is about 2% inches and whose over all lengthis about 51 inches, asvat present commerciallymanufactured, for instance, a

jacket of this sort may be about 5% inches panded of about 2%- inches, and may be corrugated to such an extent that if the corrugations were completely flattened its diameter would be, say, from to greater than this. As shown, the desired action of the jacket 1 as a whole is secured by means of a paper band or sleeve part 4 arranged at the end 5 of the jacket part2 where the bowl 6 of the lamp bulb lies, this band being put in place either before or after v 3 is inserted in the jacket 2, and being prefthe' lamp erabIy placed inside the j acket2 rather than I jacket 2.

outside it. It is not necessary to paste or otherwise secure the band 4 in place: it may simply be left loosely telescoped in the The band part 4 shown in Figs. 1, 2-a-nd 3,

.it'will be seen, is corrugated like the jacket (part 2 with which it is used. This band 4,

furthermore,isprior to insertion thereinof about the same diameter as the jacket 2 and is cori ugated to about the same extent, and

'. its width is slightly greater than the distance from the plane at about .7 where the lamp 3 is of greatest diameter to its tip 8.

Such a band may consist of a portion of a jacket like that with which it isused, and

1 for a 25 watt lamp such asabove mentioned 45.

it may then be about 14 inches wide. Even though this band or sleeve part '4 be so in serted in the wrapper or jacket part 2 that the corrugationsof the acket part and those of the band part exactly coincide, as shown in Fig. 1, so that it becomes in eifecta liner, its presence will keep the tip 8 or the bowl 6 of the lamp 3 at a-safe distance from any surface against which-the corresponding end 5 of the jacket part 2 lies. action is such that the lamp 3' is, in effect, re-

siliently supported .or suspended in the jacket 1,-so that if, for example, one places the end 5 of. the jacket 1 on a table and presses on the lampbase 9 so as to push the lamp forcibly down in the jacket 1 until the tip 8 comes. in contact with the table, the lamp 3 will jump back away from the table as soon'as it is released; What with this and the corrugations of the jacket 1, therefore, the lamp 3 is completely protected Moreover, the

The sleeve paper known as chip is cheap and satisfactory. As shown, the strip 4 is of the same width as the sleeve or band 4 of Fig. 2 (say 19; inches for a 25 watt lamp such as above mentioned) and of such a length that .when it is put in place in the end of the Wrapper or jacket part 2 its ends will not overlap. It is arranged with its plain faced side outward, so that its corrugations will not fall in those of the sleeve 2, and thus it will always ofier a very considerable obstacle to movement of the tip end of the lamp toward the corresponding end of the part 2. When this form of packing is used, the expansion of the part 4 which movement of the lamp toward the end of the jacket part 2 at which its tip lies would necessitate will beyieldingly but effectually resisted by the resistance of this end of the jacket to expansion. This form of packing part and that shown in Fig. 4 give rise to advantages that may make them in many respects preferable to that shown in the other figures,especially for lamps larger than the 40 Watt tungsten lamp of the multiple type, for example.
