Box.

To all whom t may concern Be it known that I, ARTHUR P. BEAUPR, asubject of the King of? Great Britain, re-

siding at Montreal, Province of Quebec,

Canada, have invented certain new and useful Improvements in Boxes; and I Vdo-hei'ebydeclare that the" following is a full;v clear, land exact description of the invention, such as will enable'others skilledk in the Vartl to which it appertains tomake `and useV the Same. v

' The present 'invention relatesto boxes made from thin light material cons'istingof L,lamii'iatedwood, that is, sheets or veneers which are laid and secured together to form a light and strong material forboxes, and A'more particularly to thecorner bindings for said boxes which are used to protect. and se- 'cure the meeting edges of the sections of the box .which are joined together and which extend at angles to'each'other.

'In United States patent to John' E.'David son,'Number 1,087,530, dated February 17,

1914, 'a corner binding is disclosed )vhich consists of a plurality of thin laminated sheetsof woodnh'aving the grain ofthe wood inthe different layers arranged in cross relation and the layers are formed with a sharp angle, so that' the interior ofy theV binding may 'fit closely tothe cornerrof the box.. In actual use of the box, I have found that such corner bindings are very unsatisfactory due to the fact that they are provided'with sharp angles or bends, and in the'process of manufacture of such binding the sheets naturally stretch in forming such sharp angles`v and Atherefore weakens the' binding as a rupture takes place in one or more ofthe layers and such defects are not noticeable' from the exterior of the-box until the box has been *undergoing additional strain duringl shipment. Also the corner binding as disclosed in this patent is still further objection-able due to the fact that the grain of the; wood of the inner and outer'sheetsextends'in a Y longitudinal direction andthe-grain of the intermediate sheet extendsva-t right angles to the grain ofthe inner and' outerl sheets, and therefore when the grainvofvthe wood extends in this direction the sheets areweakcned', as the woodvwould readily break with the grain and in forming sharp fcornersto y the bindings the sheetshavingtheir grain runningv in alongitudin'al direction will be "greatly 'weakened in' fact it 'isE necessary Specification of Letters Patent.

to extend the grain of the lwood iii di# Y rections to forin such sharp corners orv apexes ofthe angular corner bindings.

Metallic corner bindings have heretofore been extensively lused, but owing to: the i great increased'cost yof metal at the present `time such bindings are not desirable and therefore non-metallic bindings at the rp resent'time` are in great demand; valso boxes having'these non-metallic bindings must be used for more than one shipment and for this reason very strong'and durable'corner bindings must be employed. 'l 1 Y It is the purpose of theV presentL invention 'A to generally improve this class of boxes and provide a corner'binding therefor, soV as to increase the life of the'box and lstill contain the qualities such as lightness, strength and durability which are especially desirable.-`

yWith the above and other objects in view which 'will hereinafter appear as the 'description continues, "the invention consists of the novel features of construction, coinbination and formation of parts as will be hereinafter more fully described and particularly pointed out in theappe'nde'd-claim.

In the accompanying drawings has been shown a simpleand preferred' form; of the invention, it being, however, understood that no limitation is necessarily madelto the'precise'structural details herein exhibited,'but the right is herebyreserved to any changes, alterations or modifications to whichY recourse may be had that come within the A scope of the claim without departing from the spirit of the invention or sacrificing the efliciency of the same..`

In the accompanying drawings: Figurel 1 is a sectional perspective view of eral views.

The sides,-bottom and top .of the box hereinshownfwhich are indicated bythe numeral" 1,"ai'efeach 'formed' from builtfiipl lair reference characters throughout the sevveneers consisting ofV laminated sheets arvus .ranged in cross relation, secured together and permeated ,byy cernentnand are :formed by the use of the veneerimachineof any* Vwell known or preferred construction. Thev Y grain of thek inner and outer sheets are arranged longitudinally and in parallel relafv `tion with each other whereas the grain' of the intermediate' sheet extends @at right angles to the grain of the inner and outer sheets,l thereby greatly fincreasingrthe strength ofthe sections and such sections will have greater Strength and durability Y than if the sections were .madeof a single sheet of wood of equal thickness.

the rectangular cleats 2 which extend along thescorners of theinteriorof the box'.V The adjacent edges of 'the sections terminate at the corners of the cleats, as better illustrated .in Fig. lof the drawings, and itis therefore necessary to protect-these corners with .a binding; Y

lThis binding preferably consistsof three sheets or veneers as better illustrated in Fig. .4; The inner and outersheets 3 and 4 respectively are arranged so that their grain will extend parallel and ina diagonal 'direc-l tion as represented by the numeral 5, whereas the grain 6 ofthe intermediate sectionV extends in a diagonal direction but opposite to or at right angles tothe grain of-the sections 3 and 4:. VIn the prior bindings the grain of the inner and outer sheets runs in a longitudinal direction and therefore the strength of these sheets is greatly impaired,

but by running-the grain of the wood "in a diagonal direction asdisclosed in the present application the strength of thecorner bindings is greatly increased.' These corner bindings may contain three or more sheets lof .Wood as will be obvious, to increase the thickness orf strength if so desired and these corner bindings are formed '.by the use of a veneer machine in any well known manner.

' In forming such corner bindings,l theY strips are allowed to dry under heat andare then ing these angular bindings the :bends oi' vplaced vunder the pressure ofthe'molds, so

0` that they are formed in thef'desired configurationl These corner bindings are, of course, angular in cross section, but in formapexes' are given a long curve so fas to prevent stretching `of the sheets or fin an'y manner impair the strength at the bend. In the corners-of boxes herebefo'reused `and particularly that shown in the patent above lreferredfto, the VedgesV ofl thersections of the box overlap each fother sov as to from a contiguous point andy therefore itis necessary to give the cornerbindings of such A boxes a sharpl bendso that theyffwill Mt snugly lupon such sharp edges. l I f .the corner binding inade in accordancewiththe present invention was appliedto` boxes hav= g Having thus fully describedniy ing'such z'sharp cornersA thelong bend given tothe corner 4bindings would be very unde ,sirablaas it would not add to the strength Y 'or protect such corners. "f The adjacent edges of the sections of the box as herein' dissuclrlas that set forth in the presentapplic-ation would extend over theselspaces 8 and fully protect the corners .of-the box. As

the sections of thevbox dor not overlap one another, it is therefore necessary to provide the cleats 2, so that the sections may be conl nected together. Injconnecting the sections The inner edges of the lsections rest upon together and applying the vcorner bindings thereto, Jthe nails 9 are employed which extend Athrough the corner bindings, sections soVV Y ofthe box and theniinto the cleats 2, thereby rigidly connecting the :seotionsvof thel box together and employing only a single ffas- ",tening elementfor connectingY the sections ofthe boxtogether as well' as' for fastening the: corner bindings 'tothe box;v In

Fig'. Vl ofthe drawings Iy have illustrated :wherein nails may be used for connecting :the sections lof the `box to vthe cleats 2, but

thesefastening elements are only;used whenV metallic strips are the box.V i

I have found i by actual experiments exy tending over-aI long period during which containers inadea'ccordi-ng .to my invention Vha-'velbeen shipped as far asfto Vandfrom YIndiathatfthe provision of the space 8, adds greatly to the lifeof the container, by'reason of the Vfact that the cornerl bindings are thereby rendered resilient." "In shipping #long distancesthe containers are' frequently "handled and consequently knocked, aboutl considerably; Moststrains and impacts fall` upon the corner edges as will be apparent, and consequently the vresilient nature ofthe curvedfportion -of the binder prevents pre- .f' mature'fractureiof the latter; s Furthermore,

.fronith'e arrangement of the cleatsv or stays 2.at the corners of the receptacle and the connection of Vthe sides of the receptacle thereto, it will be appreciated that these sides will vbe v,rendered very strong, and durable and thatirrespective of the'stress applied tothe reinforcing elements 8, they will remain rigid, thus preventing damage to the 'receptaclecontents Any stress upon the reinforcingelements 8 will be taken lcareiofy vby theusa'me 'and byieas'on of the connecltion thereofwithathe cleats 2, fsuchstress Y' will be'evenly diffused throughout the elen ments and thecleats 2.
