Patented Jan. 18, 1949 ADJUSTABLE AND REMOVABLE COIWPART- MENT AND PARTITION FORMING DEVICE FOR TRAYS Harvey H. Yawman, Le Roy, N. Y., assignor to Union Steel Chest Corporation, Le Roy, N. Y., a corporation of New York Application June 29, 1944, Serial No. 542,758

This invention relates to adjustable and removable compartment and partition devices'for trays.

Trays constitute an essential element in workmens tool boxes, cash boxes, fishing tackle chests and chests or boxes for general utility purposes. These trays are usually rather shallow and elongated and adapted to hold a variety of small items such as screws, nuts, nails, coins,- stamps, small tools, etc. i

In order to segregate these small items and articles and make them readily accessible in the trays, it has been proposed to provide a substantially flat plate with vertically upturned sides to partition the tray and thus form a compartment. One of these partitions or compartments can be used in a tray at various positions or locations to receive certain segregated articles therein.

The problem in connection with. the positioning and holding of the flat partitioning plate with vertically upturned sides in trays and preventing accidental displacement of the partitions, is one that is ever present with the prior art devices. These partitions frequently come loose and are accidentally displaced and the segregated articles in the compartment formed by the partition are intermingled with other articles in the tray and the workman or user has to sort and pick out, say small items such as screws, nuts, nails, coins, stamps, etc., from amongst all the other articles.

The adjustable and removable compartment and partition device as embodied in my invention overcomes all of the objectionable features of the prior art devices. I provide a simple device which not only partitions the tray but also forms a definite compartment by means of partitions. Moreover, the attaching and securing of my device in place, due to its inherent structural characteristics, the intermingling of small nuts, screws, nails, coins, etc., and the like with other articles in the tray is positively prevented, the said articles being at all times maintained within the compartment formed by means of partitions.

The primary object of my invention, therefore, is to provide an adjustable and removable'compartment forming and partition device for use in trays or similar containers.

Another object of my invention is to provide an adjustable and removable compartment and partition device whereby when the same is associated with a tray or the like, a definite compartment will be formed between two walls which form the partitioning for a portion of thelength of the tray.

Another object of my invention is to prqvide 5 Claims. (Cl. 220-2l0) an adjustable and removable compartment and partition device wherein, due to the inherent characteristics thereof, the same will be securely and fixedly held in. positionwhen inserted in or associated with the tray.

,Another object of my invention is to provide an adjustable and removable compartment and partition device for trays wherein the connection of the device with the tray is effected by a simple means and effects a resilient or yielding connection which prevents accidental disassociation of the device from the tray.

Another object of my invention is to provide an adjustable and removable compartment and partition forming device which is readily stamped from sheet metal or similar material and which can be produced economically and rapidly by stamping or other known methods.

Additional objects will become apparent in view of the specification hereinafter.

The invention will be-more readily understood by referring to the drawings in detail, a description of which follows:

,The tray T is of conventional formation and as will be seen it is relatively shallow and elongated and is preferably, as shown, of rectangular formation. This tray embodies opposite similarly formed side walls 8, similarly formed end walls 9 and a bottom I0. It is to be noted that the side Walls adjacent the bottom ID are curved as at H, both lnteriorly and exteriorly of the tray, and the same is true of the connection of the bottom In with the ,end walls 9, ;As is usual, the tray is provided at its top with a bent-over or rounded head portion l2.

My adjustable and removable compartment and partition device is best seen in Figs. 1 and 6. This device consists of a substantially .flat bottom I3 having at opposite sides thereof "integral upstanding partition and

compartment forming walls

14 and 15. The respective ends Ma and l5a of the walls M and [5 are inclined upwardly from adjacent the bottom of the device and take the shape of the inclined interior opposite side walls of the tray throughout a major portion of their depth and also take the shape of the curved portions H', which are adjacent opposite sides of the interior of the bottom of the tray. The curved portions of the walls 14 and I5 are denoted at Nb and I51), respectively.

The major portion of the bottom of the device I3 is flat and is integrally connected with the upstanding walls M and [5. However, the opposite ends l3a of the bottom of the device are discon nected from the upstanding side walls 1'4 and [5, as denoted at "[6. "The disconnected opposite end portions of the bottom are curved to assume the shape of the interior curved portions ll of the tray and in effect constitute flexible tongues and provide'for the resilient connection of the device wlthft'h'e tray as will be explained hereinafter. The blank from which the adjustable and removable "compartment and partition device is formed is clearly shown in Fig. 5 in a flat state and as such can be readily stamped from sheet metal or other suitable material. When the blank is stamped as shown in Fig.5 it is simply necessary to bend or fold the wall M and ldupwardly so "as to place them at substantially right angles with the bottom "I3 and -then bend or otherwise form the ends of the bottom 13a into the curved position as shown in Fig. "6. y

In viewing the device as shown particularly in Fig.6, it will be seen that the curved tongues which "are in effect a continuation of the bottom extend between and substantially register with the curved oppositely disposed lower curved portions lie and 15b of the respective upstanding walls le an'd "t5. 7 c

As will be seen, the curved extensions 'or tongues 13a or the bottom 13 extend upwardly to a point coinciding with the curved bottoms Nb and -l'5b or the walls 14 and f5 and terminate considerably below the upper edges of the walls 1'3 and i5.

formed, the device prov-ides a compartmerit denoted generally at C and the upstanding walls and l5 serve as a means to partition a remaining portion of the tray. It is preferable that the top portion of the "walls of the device extend only to the top bead $2 of the tray. In other words, the device, when inseited Within the tray, is flush with "the top of the tray.

The adtusta'ble and removable compartment and partition forming device is provided in its bottom with adepending securing and locking tab 11. This securing and locking talb .is preferably stamped from the material of :the bottom l3 and is pressed downwardly to form a shoulder portion 18 anda portion H] which extends substantially parallel with the bottom of the tray when the device is "inserted therein. It .is to be understood that the securing and locking tab I! is merely "anjillustration of "one way for securing and-locking thedevice in its association wlthfth'e tray. other means, such as a bayonet connection '(notrshown) may werl b'e used.

"Ilhe bottom of the tray F is provided with suitably spaced openings 20. These openings 20 sure.

provide for the lockin and securing of the compartment and partition device within the tray and also provide for adjustability whereby the device may be inserted in various locations within the tray, or so that several of the adjustable and removable compartment and partition devices can be inserted and associated with the tray. For purposes of illustration I have shown only one of my devices secured within the tray. It is quite obvious that when the device is secured within the tray as shown in Fig. 1, a definite compartment is formed by the device itself within its upstanding walls, and these upstanding walls partition the tray into other compartments whereby various small articles ma either be placed in my device or in the other compartments formed in the tray.

In positioning and securin my adjustable and removable compartment and partition device within the tray it is simply necessary to align the depending locking tab H with any one of the selected openings "-20 in the bottom of the tray and by positioning the device thereabove with the tongue in alignment and moving the same downwardly within the tray the tongue 5'! passes into the opening 29 and then, by a slight slidin forward motion, the tongue engages under the bottom of the tray and the wall of the opening engages the shoulder formation Ill, whereby the device is securely held in position.

Then, too; when my device has been inserted within the tray as just described, the downward movement of the device results in the flexible curved tongues l3a resiliently engaging the opposite interior curved bottom portions H of the tray and this provides for a very close lit and when the can 11 has been inserted Within the opening 20 and is beneath the bottom of the may, the tongues 4 3a provide in effect resilient connection ol t'he device as a Whole with the tray.

In other words; when the adjustable and removable compartment and partition device is in sert'ed, the tongues 13a exert a slight pressure on the intenior curved side walls ll of the tray and this tends to provide a flexible connection with the tab 1 lholdin'g the device *down, whereas the tongues 13 a exert a slight upward pres- .In addition to this there is a tendency for the upper edges of the oppositely disposed tongues 341 to bite into or grip the oppositely disposed interior side Walls of the tray. This is a further -means to prevent any accidental displacement of the device from the tray once it has been inserted therein. Of course, the looking tab 11 plays an important part in securing the device within the tray.

Should it be 'desirableto disassociate the compartment and partition forming device from the tray, all that is necessar is to grip the device the fingers, slide the same so as to release the looking tab l'i' from within the opening 28 and lift the device as a unit out of the tray and then re-dnsert it as hereinbefore described.

When one or more of the devices are inserted and locked within the tray it will be seen that the compartment C is formed by the device itself and that portion T of 'the interior side Walls of the tray. This compartment C then is closed by its bottom and side walls and that portion T or t-"He side wall of the tray itself and thus prevents accidental displacement of any articles therein.
