Abstract
Abstract A device for dispensing articles comprises a vertical chute for a stack of articles. The chute is closed from below by a pivotal element which supports the stack. A spring pivotal with the element has a portion extending over the front of the element to engage and support the penultimate article in the stack when the element is pivoted to discharge the lowermost article of the stack. A second spring mounted in the chute at the rear of the element also serves to support the penultimate article.

Claim 1
Independent Claim
314 words
In a device for dispensing articles having walls forming a vertical chute for receiving a stack of articles to be dispensed from the bottom portion of said chute and having a discharge opening at the bottom of the chute, the combination therewith of a bottom closure element pivotally mounted at the bottom portion of said chute, said closure element haviNg a first portion extending into said chute for engaging and restraining the lowermost of said articles and having a second portion extending upwardly of said first portion and out of the path of movement of said articles in said chute, said element being pivotable about its pivot axis to move said first portion to a position which permits the discharge of the lowermost article from said chute through said discharge opening and to move said second portion toward said chute first spring means engaging said second portion of said closure element and extending above the latter and out of the path of movement of said articles in said chute, said spring means being movable with said second portion and into a position within said chute in which said spring means engages a first portion of the penultimate article and restrains it during the discharge of said lowermost article, and second spring means at the side of said chute opposite from said first spring means and extending into said opening for preventing tilting of the penultimate article during discharge of the lowermost article through said opening, said second spring means having two positions, said second spring means in one of its positions being engageable with the lowermost article for holding said second spring means in said one position and being movable into the other of its positions upon discharge of said lowermost article, said second spring means, in said other position thereof, engaging a portion of the penultimate article different from said first portion thereof.

Claim 3
Dependent Claim
61 words
A device according to claim 1, wherein the first spring means has opposed end portions engaging the under side of the said closure element, and a further portion, said further portion being in the form of a loop engaging the upwardly directed portion of the element with an upper edge of said loop extending above said second portion of said element.
Claim 4
Dependent Claim
65 words
A device as claimed in claim 1, wherein the second spring means is U-shaped and comprises a pair of arms and a transverse portion connecting the arms, and one of the walls of said chute is a rear panel having bracket means and slots, the transverse portion of the second spring means being engaged in the bracket means, and the arms extending into the slots.
Claim 5
Dependent Claim
123 words
A device as set forth in claim 1, further comprising slide means mounted beneath said closure element and movable from a first position in which it prevents a discharge of articles from said discharge opening to a second position in which it permits the discharge of articles from said opening and linkage means interconnecting said slide means and said closure element for moving said slide means into said first position upon movement of said first portion of said closure member into said position thereof which permits the discharge of the lowermost article from said chute and for moving said slide means into its second position upon movement of said first portion of said closure member into said chute for restraining the lowermost article.
