'llhis invention relates to packing trays and cases for porcelain shades and like l ragile objects, and is an improvement on my Patent No. 1,059,359, April 22, 1913, and a companion to my application tiled concurrently herewith in which a series of downwardly projecting spurs are shown as the sole supports tor the shades.

1n the accompanying drawings, Figure 1 is a plan view of one oil the trays as it appears when ready to be used in the packing case. l ig. 2 is a sectional elevation of one oil the creased blanks before cutting out the spurs. Fig.3 is a sectional elevation of a packing case and a series 01 trays and shades therein in shipping relations. l ig. t is a sectional elevation of one of the packing rnernbers as otherwise seen in Fig. 2. Fig. 5 is a lull side elevation ct said member and ig. 6 shows the same as torrned up in the cutting dies with two spurs turned in opposite directions The material and distinguishing ditler once in this application over the patent mentioned is the series of spurs E2 and B in the edge at the central opening therein, and as compared with the companion application reterred to the difference lies in the construction and use of the are or tongues and in the total size ot the opening, the present spurs being cut to a length corresponding to the width of the side wings, or about one-fourth the width at the opening tor the shade and adapted to be utilized as supports tor both the trays and the shades as shown. To these several ends 1 first cut or stamp out a blank B to inalcethe tray, as seen in Fig. 3, said blank being ct corrugated paperboard and term the'same with wings d and 5, respectively, at its sides and spurs 2 and 3 about its center... The said wings are turned up andv down respectively, and overlap other wings of the trays next above and below as set forth in said lactters Patent, and the said spurs are struck on radial lines in the edge ot the opening in which the shade Sis seated and are cut to a length about equal to the width oil the said wings. The bracing spurs 2 serve as supplementary supports tor the trays, especially when excessively heavy objects are shipped and the trays require supports at the middle to prevent sagging. Hence it" the shades or other objects carried are unusually heavy every other spur. is turned into bracing position while the others are bent downward and bearugainst the body ot the shade on a plane beneath the plane of the board as shown. The spurs that are turned upward into bracing relation bear against the side ot the shade above the tray and allord both a lateral cushioning support tor the shade and a direct support for the tray neat above. its braces they, co-act with the side wings in sustaining the load both in transit and at rest.

'lhe several spurs 2 and 3 herein are shown as narrower than those in the coinpanion application, there being twelve as the purposes of a hinge with spring eiiect to the spurs. This means that all the spurs have segmentally curved creases 6 at their base whichever way they are to be turned,

and the creases generally-are on the side to which they are turned, up or down. The said creases also are on atrue circle or on segments 0t circles for the respective spurs and may be on opposite sides when the spurs are to be bent oppositely, of course with spurs compare tively narrow at their base it is possible to use a continuous crease for all the spurs on the same side and turn the spurs in either direction therefrom, because a relatively narrow spur has such a short crease line that the spur can be bent up or down with out rupturing or destroying the hinge. In such case 1 may make the entire crease on the bottom at the tray and thus preserve the spring sustaining effect tor the shades in the down spurs 3 while the upturned spurs do not lose in sustaining eh'ect. In

either case the spurs cooperate to protect theshadein transit and handling, and the former objection in the patent cited of having nothing but the sharp edge in the hole of the board to engage the shade and the consequent tendency to breakage is overcome. Of course I do not in this case rest the shade exclusively in or upon the down spurs as in the companion application above mentioned, and show the base of the spurs at the edge of the tray as in supporting relation to the shade, but it will also be noticed that the tray has no sharp edge as such like the patent construction but has the widely extended bearing of the broad base portions of all the spurs together, and the total effect is to so distribute the sustaining surface that what otherwise would be an actual edge support is minimized and relieved if not actually displaced by the surfaces of the said spurs. As a result I can carry shades with this construction with perfect safety whereas an all edge support would break many.

The spurs 2 are provided with straight transverse edges because the said spurs have alternative uses, and when used as braces they require straight edges to bear against the tray above and also must have alength corresponding substantially to the width of the wings 4 and 5. If the crease 6 is all on one side any of the spurs can be bent upward, but if each spur has its own crease every other crease would be on the top side of the board. I make them both ways. Of course the spurs are stiff, like the board, and creasing is necessary in order to get a hinge or bending line where it is wanted. Furthermore creasing produces the shoulders a: and y, which are material.

Speakin of the opening or hole in the tray 'for t e shade I mean the full width of the opening as it appears when the spurs are turned to supporting position and the shade rests on the base of said spurs. Otherwise there is an opening within the ends of the spurs as seen in Fig. 1, but this is not the opening referred to in the claims, but only part of it.

The wings 4 and 5 have creases 9 on which they turn to supporting position. Emphasis needs to be placed on the creases for the spurs because without them it is physically impossible-to turn the spurs up or down with uniformity as to the line on which they turn and without breaking the stock on the bending line and rendering the spurs practically worthless for the purposes named. This is so because the spurs cannot be bent down on curved lines without breaking, nor on straight, and in no case will all the spurs break on the same lines. But by creasing the stock at the base so as to form hin es for the spurs they simply turn on said inges and no breakage or rup ture of the stock occurs.

What I claim is:

1. In packing devices for fragile articles, a tray made of three-ply paper board having supporting wings at its four sides and an opening in its middle and radially disposed spurs terminating at said opening having approximately straight transverse edges and of the same depth as said Wings, the said board being creased from side to side in a circle at the base of said spurs and adapting the spurs to be turned to supporting position whereby the said trays are provided with means of support immediately next to the article carried in addition to the wings at the sides.

2. In packing devices for porcelain shades and other fragile articles, a tray consisting of three-ply corrugated paper board smooth on both sidesand having a circular opening provided with a series of tapered spurs about the same having substantially straight transverse terminal edges, the said spurs projecting forward from the edge of said opening and said tray being creased at intervals on opposite sides from side to side on the line of said opening at the base of said spurs to enable the spurs to be turned either up or down into supporting position according to the crease at the base thereof, and said tray provided with wings at its sides adapted to be turned to-right angles into supporting position and having a width corresponding to the length of said spurs.

In testimony whereof I aflix my signature in presence of two witnesses.
