HOLDING COMPARTMENTS FOR PAINT TABLETS IN SHEET METAL PAINT BOXES Filed Feb. 26. 1932 JNVENTUR Patented Nov. 7, 1933 HOLDING- CQMPARTMTNTS For: PAINT TABLETS IN SHEET r-An PAINT Boxes] Hugo Liebetruth, Nurembergy'Germany, assignor to A. Liebetruth & Co. Gesellschaft mit beschrankter Haftung, Nuremberg, Germany Application February 26, 1932, Serial No. 595,362, and inGermany January 30, 1932 3 Claims;-. (61541-4) This invention relates to improvements in the holding compartments of holding frames for paint tablets, which are to be inserted into the sheet metal base of paint boxes. The known 5 paint holding compartment, to which the improvement relates, has high transverse walls, which are supported on the bottom ofthe base by means of their obtuse angular points, and low longitudinal walls on which supportingbars for the paint tablets are bent horizontally. As the height of these longitudinal walls corresponds to the thickness of the tablets inserted from above on to the supporting bars, the upper surfaces of the paint tablets are flush or nearly flush with the apex of the paint holding frame bars. The paint tablets can be offered for sale in this form in an attractive order and arrangement. The greater portion of the paint tablets, which are mostly only thin in cheap childrens paint boxes, is hidden and only the upper surfaces of the paint tablets are visible. However, the attractive arrangement and the secret of the particular thinness of such paint tablets do often not remain undiscovered very long, because the loosely inserted paint tablets are not secured against falling out. In order to prevent the falling out and mixing up of the paint tablets already at the dispatching of the paint boxes, the space between the domed lid and the paint holding frame was hitherto filled with a piece of corrugated cardboard, placed on an intermediate sheet of parchment paper, in order that the paints do not stick thereto in damp weather. Further it sometimes happens in the shop, that, when a box has been opened the lower part of the box is laid onto the lid instead of the lid on the lower part. The result is, that most or all the paint tablets fall out. This often results in the box not being bought. The corrugated cardboard is mostly no longer reeO placed, after the paint box has been used the first time, so that thereafter mixing up of the paint tablets cannot be prevented and the box is always in disorder. Children are not capable of replacing the mixed paint tabletsin their proper compartments marked with the name of the paint on the frame ribs so that they rememher many of the colors under wrong names.

The invention has for its object to construct the holding compartment for a paint tablet so that it secures under all conditions the paint tablet loosely inserted from above against falling out. For this purpose knob or bead-like projections are formed by depressions in the transverse walls of the compartment. The paint tablet is inserted with one of its short sides under one of the projections and its other short side is pressed on to the oppositeprojection so that the lower edge of this other short side tendsto slide off the projection. This is possible because the transverse side wall of thecompartment made of very thin sheet iron and against which the one short side of the paint tablet already bears under one of the projectionayields resiliently. When the up "ge of the other short side of the paint tablet pped below the apex point or the apex line of the other projection, it slips automatically completely under same. The paint tablet is then pushed back in this direction by the resiliency of the end wall against which it was thereby pressed. 7 The paint tablet is then .held securely below the two projections so that it can no longer fall out even if the box is shaken in open condition and upside down. This secure hold is already obtained by very slightly raised projections which are scarcely apparent. The projections do also not damage the paint brushes because they have no sharp edges. The painting water does not cause the projections. to rust because they are coated like the rest of the tablet holding frame with waterproof paint. Although the projections reliably hold down the paint tablets they do not prevent interchanging of the same. Consequently the object in View is attained in a perfect manner.

Two embodiments of the invention are illustrated by Way of example in the accompanying drawing in which:-

Fig. l is a top perspective View of ment.

Fig. 2 is a cross section showing the holding projections. V

Fig. 3 is a top plan view of the compartment with a paint tablet inserted.

Figs. 4 to 6 show in similar views to Figs. 1 to 3 a modified form of construction with means for holding down the paint tablets.

In Figs. 1 to 3 each holding compartment a of the holding frame I), c, d resting with its edge bars I) on the base, not shown, has two transverse walls j which bear with their obtuse angular points g on the base, and two low longitudinal walls h, from which the'supporting bars 2' are bent horizontally along the edges it. According to the invention knob or bead-shaped projections a compartm are pressed from the transverse walls 1 and extend into the compartment preferably directly under the edges of thetransverse frame bars d. As is clearly shown in Fig. 2, the projections m prevent the paint tablets o inserted thereunder from rising and therefore from falling out. The 110.

projections may be provided on the longitudinal walls 11. instead of on the transverse walls ,1. The reason why the insertion of the paint tablets from above is possible in spite of the projections and how these projections act as holding down means has already been explained in the intro duction to which reference is here made.

According to Figs. 4 to 6 flaps p are stamped from the transverse walls 1 of the compartment c: These flaps are bent up vertically to enable inserting of the paint tablets from above (Fig. 5) and then they are bent into the horizontal position. In this instance the holding frame must also be enamelled on the under side so that nobare under-surfaces of the sheet iron flaps p rest on the paint tablets. If the surfaces were not also enamelled, the painting water would cause rust to form on the underside which would be dis tributed over the paint tablets by the brush when brushing over the surface of the paint tablet, thus resulting in a spoiling or discoloration of the color of the paint. Apart from the'nec'essity of enamelling the underside of the holder frame which is not necessary in the form of construction with projections,- the hairs of the brushes would be quickly worn by the sharp edges of the holding down flaps p. In spite of these apparent disadvantages protection is alsosought for this form of construction.

I claim:

1. A holding compartment for paint tablets,

comprising in combination with the box proper, transverse walls bearing with obtuse angular points on the bottom of said box, shallow longitudirial walls bent horizontally inwards to form supporting bars, and projections for the paint tablets resting on said bars pressed inwardly from said transverse walls.

2. A holding compartment for paint tablets, comprising in combination with the box proper, transverse walls bearing with obtuse angular points on the bottom of said box, shallow longitudinal walls bent horizontally inwards to form supporting bars, and projections for the paint tablets resting on said bars pressed inwardly from said longitudinal walls.'

vertically upwards to allow the insertion of the paint tablet andto subsequently be bent into horizontal position on to the inserted paint tablet.
