KNOCKDOWN `IVIE'JL RECEPTACLE.

Application filed September 27, 1919. Serial No. 326,935.

Toalliti/omitmay/concern.'

.Be it known that I, I-InNnrk A. HOUSE, a citizen of the United States, and a resident of Bridgeport, county of F airiield, and State of Connecticut, have invented certain new and useful Improvements in `Knock-k down Metal Receptacles, ofwhich the following 1s a specification.

This invention relates to knoekdown metal receptacles, and has for its primary objectk to provide a collapsible orlrnoclrdown barrel or other receptacle,y the several parts yof which may be easily and quicklyassembled to provide a perfectly rigid 'structure which \vill not be liable to accidental collapse in use. f

Among the desirable features of such a receptacle, perhaps the foremost resides in the capability to resistance of` internal strains and stresses which may devolve upon the several parts when the receptacle is filled. It is therefore an important object ofthe present improvement to provide a barrel or receptacle consisting of separable parts, or sections, and means for locking the said sections together when assembled in such manner as to produce a high degree of security and provide an efficient and serviceable container which will effectively vwithstand the use andabuseto which such receptacles are subjected in shipment.

It is a further object of myinvention to provide means for lockinfr the several stavesl i or 'body sections of the barrel or receptacle in assembled relation, which will equally distribute internal strains or stresses in a circumferential and subsequently incorporated in the subsutlice for both. f

In the drawing. l have illustrated an em- 'bodiment of my inventionas adapted and applied to a knoekdown barrel, but itwfill be understood, as the description proceeds, that 'thev subject matter of the present invention may likewise be vutilized `in connection with containers or receptacles of other shapes and sizes as may be employed for many different purposes. In this drawing, each lof the stavesor body members 100 adjacent 'to its 'opposite ends is formed with an indentation 10i. rIlhe end of the stave extending from this indentation is curved or bent as clearly shown in F ig. 1to provide ar chime'section 102. From the chime, a terminal flange 103 on the stave extends horizontally and in an inward direction. It will be understood that when the several staves 100 are assembled, the parts 102 thereof form a continuous cire.y cumferential chime. As theconstruetion of the barrel or receptacle heads, and the manner of kapplying andlocking these headsy upon the opposite ends of the staves is identical in both eases, the following description of one end of the Thebarrel head atl its perimetencorresponds in cross sectional conliguration to the end of the stave as above descrlbed, the

aplan view of the locking bolt;`

barrel or receptacle kwill rially promotes the equal circumferential parts together Idistribution of the internal stresses and strains to which the bari-el is subjected to the stave ends and to the head flange. rllhese strains are thus distributed over and assimilated by agreater area of the metal barrel sections. Y

In order tov securely lock the assembled andL strengthen the same, I provide a locking member generally indicated by the numeral 110. This locking member in the present disclosure is vin the form of two ring' sections each of which has a Icross sectional configuration ycorresponding'v to theconliguration of the stavo end,

, and is thus` provided with a curved flange 111 at one longitudinal edge to receive the indented portion 101l of thek stave, a curved portion 112 to seat against the portion 102 of the stave, and horizontal inwardly projectingvflange 113 at its other longitudinal edge disposedv in superposed relation to anfl upon the flange 103 of the stave. It will thus be seen that the head 105 is rprovided with a continuous circumferential embracin portion surrounding the stave ends while the' sections of the locking1V member 110 when assembled as hereinafter described., constitute in effect, a single continuous circumferential locking unit disposed within the chime formed by the assembled stares.v

As this locking unit likewise assimilatcs the the internal strains and stresses. and equally distributes the saine tothe several stares. it will be apparent that the pressure per unit area. is reduced to minimunul and thus the strain or pressure upon the head flange isniaterially lessened. I have above referred to the locking meinberras comprising,- two ring' sections, but it will, of course, beunderstood, that three or more such sections may be provided if desired. For the purpose of facilitating' the'v arrangement of these locking; ring'sections in `operative position, I provide each section at one end designated 115 with an acutely beveled or inclined face 116 while the other end117 of said section has its end face obtusely `beveled orinclined as at 118. W lien the severaljstaves have been assembled togetherwith the head as above described,

*one-section of the 'locking and strengthenmg ring` is applied and arranged in proper position within the .chime 102, as for inbent portion 10S corresponding.

stance the section 119 shown in Fig. 4t. The other ring section 120 is then applied. The end 121 of this ring,` section is opposed to the end 11'? of the section 119 and has its end Vface correspondingly beveled so as to provide a close tight fitting joint. lllhen so arranged, the section 120 assumes the dotted line positionl seen in Fig'. L1, and has its other end lapped upon the opposite end of the ring section 119. It is therefore necessary to apply a certain amount of force or pressure to the inner side of the section 120 in order that its end 128 will properly seat `against the beveled or inclined face 116 of the end 115 of the other ring section 119. Upon the application of such pressure. the end fof the ringsection 120 rides off of the end of the section 119 and snaps into place. rlhe abuttingv inclined end faces of the ring sections will then prevent all possibility of the relative displacement of said sections. The sections of the ring throughout their circumferential exterior faces will very closely hug the conforming, end portions of the barrel staves, which will in turn transmit a tight fitting or lingeringT action of the barrel staves against the marginal wall of the'head. In this manner, the head struc-- ture of the receptacle and the stave endsis very greatly reinforced and strengthened.

In order to effectually prevent the relative displacement of the ring;` sections by externallyapplied pressures and to further aid in maintaining' the several associated parts in intimate surface contact with each other, I have provided the locking' devices generally indicated at 130, and 130a respectively. In its preferred form, this device includes a locking pin or bolt 133 whichvis adapted to be engaged through spaced 'keeper loops 131 and 122 which are struclr inwardly from the medial portion of one end of each ring'

section

119 and 120. However, it is manifest'that if desired, these lreepei' loops may be separately formed in any other desired manner and secured 'to the ring sections. The spacedy loops provide lduiding means for the locking` bolt 133. and one end of this bolt is angularly turned to afford a handle 134 while-the other end thereof is adapted to be moved over theinner face of the' opposed end of the adjacent ring section as shown in Figs. 2 and 3. Thus. the locking bolt extends over the contactingr joint faces Lof thesesections of the locking ring and securely7 holds the saine in their effective operative positions. v

In order to further enhance the tight clamping action of the locking! ring sections against the staveends, and to also prevent longitudinal shifting movement of the lecking bolt, I preferably curve this bolt as seen in Fig. 5'so that normally, it describes an arc of vgreater radius than Athe curvature of the locking ring` sections. 'Thus when the `bolt is moved to itsfeective' position, 'it Will fricti'oiiallycoact with the keeper loops and with the'opposed surface ot-the ring sec-J tions land act as a cam to exert atight clamping action 4upon the abuttingends ot the.

ring sections. In Fig. 3 isshown the condition the pin 133 assumes when putin place f within ythe lugs 131 and 132, The inside iaces of the lugs being on an arc of lesser radius thank the inner curvature of the pin, will cause the expansion ont the-pin out- Ahandle-13twith the body 'ot' the bolt. l/Vhen the bolt is thrown home to its locking position, this latter cam surface rides over and upon the edge 138 of one 'of the openings in the ring section formed bylthe inwardly struckloop 132 thereon.v This additional pressure of the cam surface 137 uponrthe plate affords an additional clamping action.

It will `Further beseen that ,as the corrieron edge 138011 thering section coacts with the handle 134 `ot' the bolt, the latter is securely locked and held against-retrograde movement from' its eltective position, such `as might otherwise be caused by a violent shoclror ofthefrece-ptacle. The'inherent resiliency of the bolt 133 in addition to the cam action of the body ot the bolt upon vthe sur'laoe oil the locking ring, assists. in positioning` the cam surface 137- in juxtaposition to the'coriicr 138. In order to release the bolt, the handle 184 must be priedor pulled inwardly away from the locking section so that tbc bolt can then be moved longitudinally. This release movement ofthe bolt is limited by' nuiansfo'tl astop lug 1.39 which'is struckinwardly from thering,- section asy seen in Fig. 3; l

When one oi the heads has been applied andsecurcd inasscinbled relation to lthe seriesI oi" staves or body members as above explained, the barrel or receptacle may then be tilled. fterhaving been filled,I the ring sections are then applied tothe other ends ot' the stares andloclzed together, and Finally the otherbarrel head is applied to cover, the I It is also y shipment.

ered in connection with thel accompanying drawing, the constructiomlinanner of operation and the several advantages of the invention will be clearly and fully Vunderstood, The several parts ofthe barrel or?y rreceptacle may be easily and quickly asseinbled and when locked together as above explained,y afford al very rigid andisubstantial structure. t rthe several separable parts is wholly :en-v

As' the locking means yfor closed within the/barrel or'recept'acle, it isr not liable to accidental engagement `and release by encountering obstructions in the' handling of the fbarrel. 'Therefore a maximum degree of safetyV andsecurity is ob?" tained. rl`he barrel or receptacle will also be practically water andjair tight so that deterioration of its contents by the action kof the elements will be obviated. fwhendisassembled, the several parts ot the' barrel',y can be compactly arranged so that they will occupy relatively little space inl storage or sembled and secured together, it .will be appreciated that the invention provides a. serv- 'iceable and `durable barrely or receptacle of the knockdowntype rand with `the yvarious structural units so correlated to each Iother that their rcooperative action results in an equal. distribution of stresses and strains and theflife of the barrel as a shipping container is correspondingly prolonged. i f i v While I have herein shown and described i one preferable and satisfactory embodiment of iny invention, it is nevertheless to be' unchanges as may be fairly "embodied within@ the spirit and scope ol thc invention `as claimed.
