portions 25 and'j2`6 and extension portions 21 and' 23. The' extension pieces 21 and 28 engage the side walls I I and I2 of the container and the angularly dis-posed portions 25 and 26 bridge across Y the corners of the containers from the bottom .Y

wall to a side wall so as to leave triangular spaces 29 and 30 along the corners of the container. Through the angular portions 25 and 26 a'series of slots 3| are formed of the cross sectional form clearly shown in Fig. 4, wherein the end walls 32 and 33 of said slots are angularly disposed-, .with--.

complished by introducing supplementary ller pieces 41 as shown in Figs. 2 and 6. These supplementary ller pieces are triangular in cross section with side walls 48 and 49 and inturned tongues 50 and 5I, as clearly shown. The supplementary filler pieces in practice will be slid down the inside of the carton engaging the edges of the glass in slots 52 which extend directly across thev apexes of the triangular portions of the supplementary ller pieces and have end walls 53 and 54, Fig. 6, extending in a common plane adapted to engage the edges of the plates As shown in Fig. 2, where rounded corners are found on the platesv the filler pieces may be modied, as indicated at 55 in Fig. 2, to make a somewhat longerdiagonal portion 56 to receive the rounded corner,- it being understood that the respect to the planes of the Vportions andA 26 so that said end walls 32 and 33 extend'at right anglesto each other and areadapted to receive the, corners-'54- and 35 cfa glass plate 36 such as a windshield, frost shield or other thin breakable plate made of material such as glass.

After the fillerhas been positioned in the bottom as above lolescribed'the sheets of glass such as windshields; frost` shields and the like arepositioned; 21S-clearly; Shown in Figs. 1 and 3,;.Wherein the several sh'eetis. are held spaced, as indicated at 31 on Fig. 3,. with their bottom corners 34and 35 held in the slots-3| and the edgeso-f Vthe glass plates engaging ,the endwalls and 33 of said, Thereafter a top filler piece 3 8, identical slots. With-the llerfzpiece 23 and havingthe same wall and angular portions and slots-as the ller'piece 23,'is-applied to the upper portions of the" sheets 36 so that. the upper corners 38 and III- thereo project "through the slots 3l of the upper,v llerpiece38'.Y

'The upper flaps I9, llare then folded to engage thawall 24 of upper ller plate 38 and the top end flaps I3 and I44 are closed and sealedand the container is ready for shipping with each of the plates held spaced from each other andz'spaced from 'thew'alls of the container.

The arrangement is such, with the edges of the several plates 36'engaging the end walls 32"and 33 of the slots 3l, that not only are the glass-plates as-a"whole', and' their "corners particularly, 'protected, but the glass itself greatly aids in-renderin"g"tliemfentire`` container more rigid and `better adapted to resist any.kind of strain or shock.

.'Th'e same-result can` be obtained by using top and bottom' lier'pieces of ther type shown-in-Fig. 5, wherein.' two' filler' pieces 4I and 42' aregemploye'd. The pieces'lI4 and 42ghave b ottomporet tions 43'.'an 1A '44,' which, as 'shown,fare adaptedto'overlie'eachfother as showniin Fig. 5. The ahgularlyi-,dispos'ed piece l5 ofthe piece 4 I .will be somewhat longer than the angularly disposedl part`46offthe piece 42, and the slots `in; lI5iwill be deeper' than'tlie slots in 46,- so that as heretoforedescribed Athefjend-l walls of the slots will extend at right angles to-'feachother and the sheets 36 will befheldwith'theiredges engaging-said end walls. Obviously' this arrangement can be reversed f.or.thej upper assemblage of pieces 4I and 42, and when the glass sheets are positioned they will: be held iny substantially the same manner asin the construction of Fig. l; Y v l `For very long sheets of -glassnsuch as sometimes are'found in;-windshie1ds, frost shields-and the like itmay be desirable to additionally reenforce thefcartgn 'at its seater and site. lateral Support to the center of theglass heets,zand .this iusufaeedges of these enlarged slots will be similar to edges 32- and 33 extending at right angles to each other and engagingvportions of .the sheet edges as indicated at 5T and 58, Fig. 2, at rightranglesg to each other.

and comprises a base member 6I vand an attached portion folded at 62 yand 63 so as to provide top flaps 64 and 65. The ends of the sheets A'36 butt; against the flaps 64 and 65. whichare folded to;v

lie in a common plane. The folds 62,and 63.

made of a fairly stiff cardboard have a 'consid-.1

erable degree of spr-ing which causes the flaps v(54 and-55 ofv both of the ller pieces 59A and 60 to ex-l ercisef balanced pressure against the `ends of the sheets 36.v This-holdsA thesheets spaced from the ends of the carton and at the'same time, by means of the springing action ofthegller pieces 59 and 60, provides a shock absorbing support for'V the respective sheet ends whereby they are held within the containerA and protected from any shock resulting from handling.

Holder members 66 are positionedagainst the sides II and I2 of the carton and engage the edges of the glass sheets 36 to hold them spaced from one another and from said side walls. These holder members comprising a sheet 61 of cardboard (Fig. 10) wherein a multiplicity -of slots 68 have been punched, said slots being widened at the center, as indicated at- 69, Fig. 10.

The sheet is folded, as clearly shown in Figs. 8 and 11, so that a base -portion 'I0 has overlying itA a second flap 'Il with the slots 68- extending across vthe apex of the holder membersA The assemblage may be secured togethenby adhesive -tape- 'I2 -or other securing -means. I nasmuch as certain of the glass sheetsi such as frost shields, have .applied .thereto a rimof-material, not shown, which might be damaged by insertion in slots 68 if the slots were narrow enoughat their entrance to engage the edges of the sheet, I have found it advantageous to expand the slots 68 at the center as'indicated.

In assembling the cartons containing the sheets 36 the bottom filler piece 60 is put in position and the holder members 66 are also positioned and the sheets 36 slid down through slots 6B. The top ller lpiece 59 is then applied with the flaps 64 and 65 engaging the ,upper ends of the sheets 36 and the carton is then closed and'is ready for shipping.

The advantages Yof my invention have been quite fullypointed out in'conneotion with the forego'- ing description. These advantages arise out of the extreme simplicity and economy of construction, equal simplicity and ease of assembling the parts and the breakable plates held by the several parts, and the extraordinary protection of the plates packed in the container While being shipped, due in part to the fact that the plates themselves greatly aid in increasing the rigidity and strength of the loaded container and do it by direct edge thrust against the edges of the several plates.

I claim:

l. A shipping container comprising a box having pairs of end Walls and side Walls, supporting devices located at opposite end Walls Within the box each having a part engageable with its end wall and having other parts connected with said Wall-engaging parts for engaging and supporting the end walls of breakable sheets such as glass frost shields, said engaging portions being so positioned as to hold the edge of the glass sheets spaced from the said end walls and spaced from the part of said supporting means engaging said Walls, and other supporting members having portions engageable With the side walls of the box and having a series of slotted plate-engaging portions positioned to receive other edges of the several sheets and hold them spaced from one another and spaced from said side Walls of the container.

2. A shipping container comprising a box, vertical strips triangular in cross-section on the inside side walls of the box with open slots across the longitudinal apices of said strips adapted to hold a multiplicity of glass sheets spaced from one another and spaced from said side walls, and members engageable with the ends of the box and with the ends of the glass sheets so as to hold said ends spaced from the ends of the box and to exercise a spring-like pressure upon opposite ends of said sheets.

3. A shipping container comprising a box,

slotted means along the sides of the box adapted to hold a multiplicity of glass sheets spaced from one another and spaced from said side Walls, and members formed of cardboard and having accordion folds at their ends, said members engaging the ends of the box and adapted to engage the ends of the glass sheets so as to hold said ends spaced from the ends of the box and to exercise a spring-like pressure upon opposite ends of the Sheets.

4. A shipping container comprising a box having pairs of end Walls and side Walls, sets of supporting devices located opposite each other along the side Walls Within the box each having a series of slots adapted to receive and support edges of breakable sheets such as glass frost shields to hold said sheets spaced from the sides of the box and from each other, and other means located at the opposite end walls of the box and engaging at one side said end walls and at the other side the edges of the plates with a spring pressure to restrain said sheets from moving endwise along the slots and to hold them spaced from the end Walls and protected against shock.

5. A shipping container comprising a box having pairs of end walls and side Walls, sets of supporting devices located opposite each other along the side Walls Within the box each having a series of slots adapted to receive and support edges of breakable sheets such as glass frost shields to hold said sheets spaced from the sides of the box and from each other, and spacer members formed of cardboard with the side edges thereof turned inwardly in accordion folds, said members engaging the ends of the box with their flat faces and adapted to engage the edges of the breakable sheets with a spring pressure to restrain said sheets from moving endwise along the slots and to hold them spaced from the end Walls and protected against shock.
