United States I Patent River Edge, N.J., assignor to American Machine & Foundry Company, a corporation of New Jersey Application March 15, 1954, Serial No. 416,278 3 Claims. 01. 312-11 This invention relates to self-leveling, storing, and dispensing apparatus and more particularly to self-leveling dispensing apparatus which is especially well suited for handling periodicals.

Self-leveling dispensers designed heretofore had been found too costly to be economically feasible for this purpose. Also, they have been too complex to be readily shipped in collapsed condition and were not of such design as to be capable of being set up on a counter.

It is an object of this invention to provide a self-leveling dispenser which is adapted for shipment in a collapsed form and which can be readily assembled by news dealers or periodical distributors.

Another object of this invention is to provide a selfleveling dispenser which is especially well adapted for positioning on a counter to facilitate the distribution of periodicals.

A further object is to provide a self-leveling dispenser wherein the carriage can move very close to the base when fullyloaded to minimize any waste of space.

Another object of this invention is to provide a selfleveling dispenser which will create the illusion of a large number of periodicals even though there may be only a few periodicals in the dispenser.

Another object of this invention is to provide a simple self-leveling dispenser which will be reliable in operation and yet economical to construct. 7

Other objects and features of the invention will appear as the description of the particular physical embodiment selected to illustrate the invention progresses. In the accompanying drawings which form a part of this specification, like characters of reference have been applied to correspondingparts throughout the several views which make up the drawings.

For purposes of illustrating the invention I have shown how a unit can be readily constructed for storing maga- 2,886,391 Patented May 12, 1959 zines. For example, in Fig. 1, the self-leveling dispenser consists of an outer shell made up of two side walls 10 and 12 and two ends walls 14 and 16. The walls are joined and held together by means of lock folds F, sometimes referred to as Pittsburgh corners, which permit assembling of the walls of the shell by sliding the folds of the same into each other to form the corners of the shell or housing shown in Fig. 3. When the housing has been assembled in the manner described above, the lock seams may be squeezed to assure greater rigidity. Since it may be desirable to secure the housing to a counter or stand the flanges 20, 22, 24, and 27 formed along the lower edges of the side and end walls are provided with suitable holes 18 through which screws or bolts may be inserted for fastening.

The side walls 10 and 12 are also provided with vertical slots 26 through which the proprietor can immediately determine how many magazines M he still has remaining in his self-leveling dispenser.

The operating counterbalancing mechanism consists of two fiat sheets of metal 28 and 3t representing the carrier platform and supporting base respectively. Said platforms are provided with downwardly extending flanges 32 and 34 which give them the desired rigidity. Interposed between the base 30 and the material supporting carrier 28 are suitably calibrated springs 43 which are held in place at their lower ends by bands 44 and 46. These springs may be varied in number and may be designed so as to be V shaped or accordion shaped in cross section to enable the carrier and base to move very close together when fully loaded. The bands 44 and 46 are spot welded at spaced intervals to the base 34 so that the lowermost coil of the spring 43 can be inserted under the bands 44 and 46 from the outside. The calibrated springs are of such design that they exert a counterbalancing force on the carrier platform in a manner similar to that described in US. Patent 2,251,874 granted to William J. Gibbs on August 5, 1941. These springs lower or raise the carrier platform a distance corresponding to the weight of each increment or decrement of material added to or removed from the platform so as to always maintain the top of the material supported thereon at a constant level.

Similar bands 48 and 50 are secured by spot welding to the under side of carrier 28. In this case the uppermost coil of the springs 43 is similarly pushed under the band from the outside. If desired, other suitable spring fastening means could be employed such as metal tabs projecting from the base and the carrier which could be bent over the springs to secure the same.

It has been found desirable to insert the springs from the outer side edge of the platforms 23 and 30 under the holding bands 44 and 46 and 48 and 50 so that said springs are securely held in position and prevented from slipping out from under bands 44, 46, 48 and 50 by means of side walls 10 and 12 and the downwardly extending flanges formed on the sides of the carrier 28 when the unit is assembled.

The distance between the carrier platform 28 and the base plate 30 which are held apart by means of springs 43 is controlled by suitable chains 36, 38, 40, and 42 which are secured to each side of the supporting base 30 and carrier 28.

The back wall 16 has two pressed-out clips 52 and 54 which are adaptable for receiving and holding a suitable display card 56.

The front wall 14 and a portion of the side walls 10 and 12 adjoining the front wall carry lithographic reproductions L of the edges of the periodicals which aresupported on the carrier platform 28 so as to give theillusion of a stack of magazines.

When periodicals such as magazines are placed upon the carrier platform 28 it descends under the weight of the magazines a predetermined distance which is correlated with the thickness of the magazine so that the top top magazine is always maintained at a constant level regardless of whether magazines are added to the stack or removed from it.

It has been found that at least one chain must be placed adjacent the perimeter of each side of the operating mechanism so as to assist in preventing the carrier platform from tilting excessively if pressure is applied to one side, such as might occur when a magazine is removed by a purchaser. Without such chains it has been found that the carrier platform has tilted to such an extent that the magazines slide to the side of the carrier and cause a jam between the carrier and the side walls of the dispenser.

While many previous devices have been developed for positively maintaining the carrier platform horizontal in self-leveling dispensers, such for example as that disclosed in the patent granted to William I. Gibbs, No. 2,449,892, on September 21, 1948, applicant has found that the cost of adding such features to a dispenser increased the cost to the extent that it is no longer economically feasible to use such devices for low cost dispensers. Up until the present time unless such a device were employed the self-leveling dispenser could not be put to a practical use because of the jamming action that resulted whenever the carrier platform would be tilted.

By means of the present apparatus applicant has provided a simple means for avoiding excess tilting and due to the carrier platform 28 being of approximately the same area as the area of the magazine when it lies flat, the stack of magazines also tends to assist in avoiding excessive tilting if pressure is applied to one side. However, because of the chain support formed along the perimeter of the carrier 23 and base 38 applicant has avoided excessive tilting and as a consequence he has provided a solution to the problem of making self-leveling dispensers without the necessity of employing a separate leveling device to maintain the carrier platform horizontal.

Another highly desirable feature of the apparatus is clearly illustrated in Fig. 8 wherein the entire unit can be shipped in collapsed form to its destination, thus minimizing shipping problems that would normally be encountered in keeping the costs of distribution down. When the unit is shipped in collapsed condition it does not have the springs inserted in place, so that the carrier and the base which are interconnected by the chains 36, 38, 40, and 42 are collapsed against one another and the side walls 10, 12, 14, and 16 are similarly stacked fiat against the base 30 and carrier 28.

The springs are nested within one another and the entire collection of springs 43 may be placed if desired in a suitable tube or container 60. The entire unit may therefore be shipped in the manner indicated in Fig. 8 in collapsed condition. in the field the periodical distributor can readily assemble the dispenser without any technical advice or assistance because of the dispensers simplicity and once the unit has been assembled it will give years of trouble-free service.

The invention hereinabove described may be varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many possible embodiments of the same. The invention, therefore, is not to be restricted to the precise details of the structure shown and described.

What is claimed is:

1. A self-leveling, storing and dispensing apparatus for periodicals comprising a material supporting carrier platform, strips of sheet metal tacked at spaced distances to the under side of said carrier, short downwardly extending flanges formed on each side of said carrier, calibrated counterbalancing springs having one end pushed under said strips from the outside so as to secure the springs from dislocation by its location between said flange and said strip, elongated strips attached at spaced intervals to said base, said strips being of such design as to receive the opposite end of said springs as they are pushed under said strips in a direction: from the outside of the sides of said base, means limiting the distance the sides of said carrier and the sides of said base can move away from each other, a rectangular shell surrounding said base and carrier to permit the carrier to move up and down freely while confining the lower end of said springs between said rectangular base and said base strips, said shell having sliding lock corners to facilitate their being joined together.

2. A self-leveling, storing and dispensing apparatus for periodicals having the features provided for in claim 1 wherein an inspection opening is provided in one side of said shell to permit a person to look through said opening into said self-leveling dispenser to see the number of periodicals stacked in said self-leveling, storing and dispensing apparatus. 7

3. A self-leveling, storing and dispensing apparatus having the features provided for in claim 1 wherein the front side of said rectangular shell has photolithographic reproductions of the edges of the periodicals to be stored so as to blend with the edges of the periodicals stored in said carrier to give the illusion of a stack of periodicals extending down to the bottom of said dispensing apparatus.
