COLLAPSIBLE BARR-EL.

Application filed August 15, 1921.

.To /i-ZZ v207mm t may con/cern.'

Be it known that l, NntsoN rl. MoLooN,

a citizen of the United States, residing at Glencoe1 county of St. Louis, and State of 'll/lissouri, have invented a certain new and vpart of this applicationA rllhis invention relates generally to collapsible containers, and more particularly to collapsible barrels. The objects of the invention are to provide a container of the class described which .is light in weight and of strong and durable construction, and which when extended` can be advantageously used in shipping material such as cement any distance without danger of said container accidentally collapsing.

Still another object of my invention is to provide a container of the class described, which, when in collapsed position, occupies very little space so that it canbe returned to the shipper at asmall cost for shipping charges, and which can be manufactured at low cost.

HWith these and other objects in view, my invention consists in certain'novel features of construction and arrangements of parts hereinafter described and claimed and illustrated in the accompanying drawings, in which- Finre 1 is a side elevation of a barrel in its extended position.

Figure 2 is a plan view of the same.

Figure 3 is a vertical cross section taken on line 3-3 of Figure 2.

Figure 4 is a vertical cross section of the barrel in itsrcollapsed position.

Figure 5 is a plan view ofthe expansion ring used to hold the cove-r of the barrel in position. Y

Figure 6 is a detail cross section taken verticali;T through theupper portion of the barrel.

Figure 7 is a fraginental view of one of the barrel flanges showing a modified construction.

Referring by numerals to the accompany4 ing drawings, 10 indicates a tubular middle section which tapers towards both ends, and is preferably made of two pieces 10a secured together in any suit-able manner, such as by which it appertains toment with each other.

Serial No. 492,361.

welding, along their inner contiguous edges 10b. 11 are intermediate sections tapering outwardly and having their innerV ends 11a arranged within the outer ends of the middle section 10. A bottom section 12 provided with a bottom wall 13 has telescopic engagement with the lower one of the intermediate sections 11. and is provided with an outwardly projecting flange 1+i and downwardly projecting annular flange 14a. The top section 15 has telescopic engagement with the upper one of the intermediate sections 11 and is provided with an outwardly projecting flange 16. rThe marginal flange of said top section is transversely curved to form an inwardly disposed annular groove 17 which forms a seat for a split expansion ring 18, the latter being arranged when occupying groove 17 to lock a circular cover plate 19 in position in said top section 15.

In order to form snug lit and seal the joint between the cover plate 19 and section 15, a washer or gasket 2t) of felt or analogous material is arranged on the upwardly presented annular shoulder 2l formed in the upper end of forni a seat for the cover plate 19.

lhen the barrel is made of pressed sheet metal the flanges can be formed by bending the metal upon itself and the sections can be pressed in any suitable shape after they are assembled together, so that said sections will have telescopic interengage- Flanges 1d and 1G are each provided with diametricalliv disposed openings or seats 22, which are devsigned to receive the ends of the folding braces 24:. These braces are preferably hinged together, as indicated at 25, and their upper ends are threaded to receive the nuts 26 which are designed to engage the outer faces of flanges 1e and 16, while shoulders or lugs 27 formed integral with braces 24; and spaced inwardly from the threaded ends thereof are designed to bear against the inner faces of said flanges so that by tightening nuts 26 on braces 24, anges le and 16 will be clamped between said nuts and shoulders 27. A set of these braces provided with each barrel, and when it is'desired to use the barrel said braces are placed in position and will hold the barrel sections in extended position and prevent the collapsing of said container.

In Figure 7 a portion of a ange of a section 15 to barrel is shown pro vided with a non-circular seat 28 to accommodate a `portion 29 ot a brace, which portion is nou-circular in crosssection so that when the nut 2G is threaded on the threaded end. 24a, said brace will be held against rotation.

in order to hold the barrel in collapsed position, or in nested relation. comparal1ively short bolts 30 are placed in position in openings 22, to h-old the ond sections 12 and l5 in engagement with each other, thereby clamping the middle section 10 and intermediate sections 1l. between lianges 14 and 16. lVhen it is desired to use the barrel, the bolts can be removed from openings 22 by unscrewing the nuts from the threaded ends of said bolt-s and moving the end sections 12 and 15 away from each other, whereby .the inner flared end of each section will engage the outer tapered end oi thersection in which said inner end is arranged.

vWhen shipping material in the extended barrel, bolts 30 can be placed within the barrel; and when shipping the barrel in a collapsed condition, braces 2a can be placed within the collapsed barrel.

Split ring 18 forms an eli'ective 'lock lwhich secures the cover plate in position upon the barrel, and the telt portion 2O provides a seal between thecover plate and shoulder 21 so that no material can es Vlape from the barrel.

A collapsible container ot' my improved construction is simple, light in weight, and being collapsible-can be returned to the shipper at low shipping charges so that it can be used again for shipping purposes, thereby reducing the cost olt'ithe containers and eliecting a great saving to the shipper.

that I claim is:

l. A collapsible container of the class dcscribed comprisinga plurality of sections havingtelescopic interengagenient, and removable hingedly connected sectional members having shouldered ends tor engaging the end sections and` locking all of said sections in extended position.

2. A collapsible container comprising a plurality of tubular sections having telescopic interengagementl including a bottom section, a coverplate adapted to be removably signature thisv positioned on the top section, and detachable hinged bars having flanged ends ada-pted to engage said top and bottom vsections whereby said container is held in extended position.

3. A collapsible container comprising a plurality ot tubular sections having;- telescopic interengagement including a bottom section, a cover plate adapted to be removably positioned on the top section, hinged bars adapted to have their outer ends detachably enga-ge said top and bottom sections whereby said container is held in extended position, and means for removably securing said cover plate in position on said top section.

et. A collapsible container of the class described comprisinga plurality ot sections hav-ingl a telescopic interengagement inclutL ing al bottom section and atop section, said top section being provided with an inwardly ldisposed annular seat, a cover plate adapted to beremovably:positioned on said seat, packingrmeans interposed between said cover plate and said seat, a split expansion ring adapted t-o be seated in saidtop section to hold said cover plate against its seat, and hinged bars havin'gtheir ends adapted to detachably engageitheV top and bottom sections and maintain said container in ein tended position.

5. A'collapsible container of the class described comprising a plurality off sections in telescoping interengagement including a bottom wall section and a top section, saidv bottoni andtop sect-ions beingprovided with outwardly projecting horizontal llanges, a cover plate adapted, to be seated in said top section, hinged members the ends of which are-l'novided near their outer ends with enlarged portions forqengaging the inner sides or said Heiliges, 'andi having their extreme ends adaptedtociproject outwardly through apertures formed iu said flanges and holdsaidicontainer in'exte'nded position, and means oreiigagingsaid Vpro jecting ends, and securing them iii-position on said` flanges.

In testimony wher-eetlv hereunto aix my 10 day of August, 1921. NELSON MCLOON.
