C Cldml. (CL 229-14) This invention relates to packing devices and particularly to devices for supporting fragile .articles within packing boxes or crates.

One object of the invention is to provide a device of simple form and construction which may be economically manufactured commercially.- j

Another object of the invention is to provide a device of novel construction which functions to support' an article within a packing box in a shock-proof manner, thereby substantially eliminating any possibility of breakage and effecting a saving both in money and time to manufacturers or lshippers of large quantities of fragile articles.

.A device constructed in accordance with the invention comprises essentially a novel suspensory member and oppositely disposed auxiliary walls within' a packing box or crate for supportl receivers.

ing the suspensory member. This member comprises a sling having rigid end members extending downwardly between the auxiliary walls and the walls of the box. The sling functions at all times to support the packed article in the desired fashion.

Other objects and details of construction of a device constructed in accordance with the invention will appear hereinafter. For a complete understanding of such a device, reference may be had to the following detailed description and the accompanying drawing, in which Fig. 1 is a sectional view of a device constructed in accordance with the invention and adapted to support a radio receiver within a4 packing box as illustrated, such view being taken along line I-I of Fig. 2;

Fig. -2 is a sectional view along line 2-2 of Fig. 1 and showing diagrammatically the elements of the receiver; and

Fig. 3 is a perspective view of the aforementioned suspensory member which constitutes one of the essential features of the invention.

Referring to Figs. l and 2 of the drawing, there is disclosed a packing box or container I which may take any desired forrnbut in the present instance takes the form of the usual packing box made of corrugated cardboard. I have chosen to illustrate the invention in connection with a radio receiver 2 having the usual vacuum tubes 3, reproducer 4, etc., since it is particularly adapted for use in the packing and shipping of such Furthermore, articles of this nature, comprising as they do various fragile and break- -able elements, such as vacuum tubes, serve to illustrate clearly the manner in which the invention proposes to pack such articles and prevent breakage thereof. It will be understood, however. that the invention may be utilized for packing'any suitable article whose construction enables the utilization of the principles of the invention set forth hereinafter.

In accordanceA with the invention, I provide a pair of oppositely disposed relatively thick walls 5 and 6 within box I. These walls are preferably built up of layers or laminations and, in the present instance, may take the form of several layers of corrugated cardboard. Since the article to be supported is substantially disposed between these walls, it is preferable that they be resilient to a certain degree and the built-up corrugated cardboard structure has the ldesired degree of resiliency. I alsoprefer to provide these Walls by inserting within the box a. liner extending completely around the interior of the box. This is evident from Fig. 2, wherein a pair of walls 1 and 8 similar to walls 5 and Ii are shown adja- 20 cent the frontand rear walls of the box. By utilizing a single liner as stated, the necessary side walls 5 and 6 are not only provided but resilient vwalls are provided entirely around the article to be packed and'serve as a cushion for 25 such article within its packing box. Furthermore the liner is more easily manipulated than would be separate walls.

Auxiliary walls 5 and 6 are of less height than the side walls of box I and function to support a 30 suspensory member 9 therebetween. As illustrated in Fig. 3, this member comprises a sling I0 having overturned ends II and I2 which are firmly attached to rigid end4 piecesor members I3 and I4, respectively. In the present instance, 35 I prefer to form sling 9 of flexible cardboard and to utilize stiff pieces of cardboard as end members I3 and I4. As is well known, many radio receivers have an arch-shaped wall I5 which constitutes the sides and top of the receiver. In 40 accordance with the invention, .the suspensory member 9 is supported by the'auxiliary walls 5 and 6 by interposing the downwardly extending rigid end members I3 and I4 between the auxiliary walls and the adjacent walls ofv box I as 45 illustra'tedin Fig. l. The suspensory member is adapted when so disposed to receive the radio receiver in inverted position as clearly illustrated. The yslings of the suspensory member adjusts itself to conform with the arch-shaped wall I5 60 of the receiver and snugly embraces the same. The sling is so dimensioned that it supports the receiver a desired distance above the base of the box.

l the packing box.

used in the present illustration is provided li'or sake of appearance and rigidity with a projecting molding edge I8 which extends around the frontedge oi' wall I5 see Fig. 2). In order to allow for this projecting edge of the receiver cabinet, sling 9 is eccentrically disposed with respect to the rigid ends I3 and I4, as shown in Fig. 3. The ends are of substantially the same width as the walls of box I adjacent walls 5 and 6, and snugly tlt within the box. Sling I0 is of substantially the'same width as the arch-shaped wall I5 of the receiver. When the receiver is properly supported in the sling of the suspensory member, the projecting edge I6 extends within the space between the sling and wall V8 provided by the eccentricity of the sling with respect to the rigid ends previously mentioned. Fig. 2 clearly illustrates the manner in which the projecting edge I6 extends beyond the sling into th space provided.

The dimensions of the various elements are such that the base of the receiver cabinet lies at some distance below the'top of the packing box when the receiver is properly supported as set forth above. In order to iill the space between the base of the receiver and the lids of the box and also to substantially immobilize the receiver within its support, I provide a shallow dished member I1 which preferably is formed of a sheet of corrugated cardboard having upturned edges which rest ilrmly against the walls of box I. This member is so .dimensioned that it. nts exactly between the base of the receiver and the lids of the box when in closed position. As is common in packing boxes of the type used herein, two pairs of overlapping lids Il and I9 are provided.' In order to maintain member I1 in proper engagement with the base of the receiver so that it atv all times exerts the desired pressure on such base, I provide a resilient spacer 2l between the closed lids of the box and member I'I. Thisspacer may consist of a sheet of corrugated cardboard rolled as illustrated in Fig. 2. It is simply necessary to place this spacer upon member I'I previous to closing the lids of When so disposed, the spacer will act as a resilient cushion interposed between the receiver base and the lids of the box. l

It is important to note the. advantages and features of the device disclosed herein which embodies the principles of the invention. Referring to Fig. 1, it will be noted that any force exerted upon the base of the radio receiver in a. downward direction will cause the receiver to subjectthe sling II to tensional forces along the sides thereof. These forces to which the sides of the sling are subjectedwill tend to cause end` members I3 and Il to .exert lateral outward forces against the walls 'o i' box I Since, however, the walls of `the box are suillciently rigid and strong to withstand such forces, the suspensory member is at all times rigidly supported as desired. Auxiliarrwallsl and t are purposely made of sufilcient strength to withstand any strain exerted upon them by the forces mentioned. Packing devices constructed as A illustrated herein have been subjected vto very severe tests and have been found to function Properly to protect the packed article even urr-v f der the severest abuse. Large weights have been placedupon the topofthe receiver to test the strength .of the suspensory memberv constructed as disclosed and previously described and to t'est also the strength of the supporting I havo'iound that .the device will readily support the weight of a normal person without any detrimental eects whatever.

It will be noted also that the tubes of the radio receiver are in inverted position and are supported only by their frictional engagement with their respective sockets. Notwithstandingl this fact, however, it has been found that the tubes are subjected to substantially no jar which would cause them to become detached from their sockets and thereby injure or break them. 10 The other delicate parts of the receiver are likei wise subjected to practically no jarring action to cause any injury whatever to such parts.

An important feature of the invention is that the various vparts constituting the same may be 15 cheaply manufactured. As previously set forth, the various elements are preferably composed of cardboard and the cost of such elements is so small as to eliminate entirely any necessity for using the packing device more than once. In other words, it is unnecessary for a shipper to have his consignee send back the packing devices so that he may use them repeatedly in shipping the articles. It will be apparent that the invention provides a simple and novel arrangement for carrying out the desired purpose. Various modifications in the details of lcon. struction are, of course, possible without departing from the principles and scope of theinvention. Only the limitations imposed-by the ap .0 pended claims are to be placed upon the invention.
