3'Cla'ims.

This invention relates todispensing apparatus, and, more particularly, to apparatus jilor dispensing articles or packages of known size and weight.

The principal object of the inventionisto provide a dispenser that displays the articles subistan'tially in'their entirety and facilitates removal of the articles by the consumer. This is accomplished by formingithe dispensing apparatus so .that'the displayed article merely rests on a platform and is not wedgedbetweenthe remaining ar- L ticles, the arrangement being such that as soon as'the displayed article is removeda new onetakes its place. 7

.Another object residesin-utilization of-gravity "to operate'the dispenser wherein-the:artioles-are stored below, and not above-thedispenser delivery point.

Another .object resides "in providing "a gravity dispenser thatis readiiyloaded in "the-same place that itis unloaded by the consumer.

A further 'ohject resides in facilitating "adjustment of the apparatus for both the weight and *height'of the articles to lee-dispensed. These-and other objects characteristic of the invention :will

be apparent to 'those skilledin-the art'as the following detaileddescription-of a preferred embodimentproceeds. I

For'convenience of illustration, I have disclosed a dispenser [that contains seven articles when 'Iully loaded, although it is understood 'tha'thy lengthening'the .devicezanyrdesired number of ,arati'cles .within reason I may be 2 accommodated.

The dispenser, in apreferred."embodiment, .ineludes a sheet .metal housing H :which has 1 two vertical compartments, compartment I forthe *dispensed articleszand compartment.Z for the bal- :ancing weights.

In addition to weight wm-a plurality of counterbalance weights W1, WZfWSQWi, and-W5, are pro- "vided, the uppermost weight,"W1,' being suspended by-fieXible-nreans"2'8 such as chains or cables. As seenin Fig. '5, *1 -may provide three members 28, 'but'itis to be understood thatin Figs. 1 to-4,- only "twoare shown in the interests of clarity. All but the lowest-weights are 'apertured as at 361 to -'accommodate *freely a master tension means 2-1.

V result is that the platform will be urged to its are supported by platform P. The seven cans are partially counterbalanced by weights W1 to We. Weights W1 to We total the weight of five cans and We adds the weight of 1 cans plus that of the carriage. In the remainder of the discussion, the weight of the carriage will be ignored because it is counterbalanced by an additional mass in the weight We.

Thus, in effect, we have seven cans on the platform and a weight corresponding to 6 cans, The

lowermost position by the cans. As can M1 is removed, an unbalance in favor of the weights that point, the apparatus may be readily concealed in a cabinet shelf or the like.

raise the platform. As seen in Fig. 2, when i the weights have dropped to the point where tension means 28 support the upper weight W1,

the platform has moved up the corresponding distance which is equal to the height of the can Me. Now tension means 21 is relieved of the weight of W1 and there remains suspended by tension means 21 a weight equivalent to 5 /2 cans, which is more than counterbalanced by the 6 cans on the platform. The platform can rise no higher under action of the weights because the unbalanced weight supported by tension means 21 is less than the weight of the six cans on the platform. Nor can the weight of the cans carry the platform lower because to do so it would have to lift the weight W1 which would cause the total effect of the weights to exceed that of the remaining cans. Accordingly, the device will assume the position shown in Fig. 2 until another can is removed.

The process just described takes place as each can is removed, and, as shown in Fig. 3, when two cans remain, weights W1, W2, W3, W4, and W5 are all suspended from the cap C. Weight We is suspended from the tension means 21, but since it is approximately equal to the weight of 1 cans it cannot lift two cans and so raise the platform from the position shown. Nor can the two cans cause the platform todrop from the position shown because to do so would require lifting of weight We, which, added to the weight of We, would be equivalent to 2%; cans.

Now, as seen in Fig. 4, as the next to the last can Me is removed, weight We must only counterbalance the weight of the last can M7. Since We equals the weight of 1 /2 cans it will lift the remaining can and drop until it rests against the stop 3 l. Under these circumstances, the last can M7 will be displayed ready for removal as seen in Fig. 4.

It will be understood from the following 'description that the weight We, which has been assumed to include that of 1% cans, can conceivably be in the range of more than the weight of one to somewhat less than the weight of two cans, not considering the weight of the carriage. This provides a certain amount of leeway and permits accommodation to be made for static friction in the parts as well as the weight of tension means 21.

The mass of the various weights can be selected to equal that of a corresponding dispensed article. Either different weights may be used, or small auxiliary weights attached as is well known in the art. The length of the tension means 28 and 29 is adjusted for the corresponding height of the dispensed article. Any suitable means Although I have illustrated a construction that embodies the invention, it is understood that numerous mechanical changes could be made by a skilled mechanic without departing from the mode of operation described. Accordingly, I contemplate that the appended claims, and not the aforesaid embodiment, be the measure of the scope of my invention.
