Patented June 20, 1950- UNITED STATES PATENT" OFFICE v 'DISCHARGING MAGAZINE ANDHOLDER Francis 0. Worth, Brooklyn, N. Y. 1 ApplicationDecember 5, 1947, Serial No. 789,782 a 1 This invention relates to novel and useful improvements in a device for retaining and dispensing a plurality of articles. I

An object of this invention is to retain a plurality of articles, preferably flat, and dispense a selected number of these retained articles.

Another purpose of this invention is to retain the articles by exerting a pressure along the edges thereof and relieve this pressure for a duration thereby permitting at least one article to drop from the stack.

Another purpose of this invention is to simultaneously move a pair of plates which are positioned beneath the articles in order to permit the lowermost article or articles to be dispensed and" to relieve the pressure exerted on the'edges of the articles.

Another purpose of this invention is to resiliently bias a panel against the edges of the articles to be dispensed and to adjustably support the 10 Claims. (Cl. 312-70) said panel so that it may be selectively raised and lowered in order to titles of articles.

Another purpose of this invention is to provide an improved and simplified device which chicaciously dispenses either a single sheet or a plurality of sheets of a preferably fiat material.

Other objects and features of novelty will become apparent to those skilled in the art, in following the description of the preferred form of the invention, illustrated drawings, wherein; I v v I Figure 1 is a plan view of, the preferred form of the invention; 7 v Q" Figure 2 is a sectional view of theinvention shown in Figure 1;

Serious difficulty was encountered in dispensing a plurality of sheet articles or units such as cards, paper/flat cartons or slabs of any material suitable for handling in the manner to be described.

Illustrated and described herewith is a means for handling (retaining and discharging) either a single sheet or a plurality of sheets of material in accordance with minor adjustments made to a relatively simple apparatus.

, The general mode of operation of the invention is to retain a stack of sheets of any suitable .the articleretaining means, whereby the articles may be released at a selected portion of the cycle of operation of the plates. Then, the retaining means is again returned to the article engaging position leaving either a single or a few sheets free of the clamping action of the article engaging means. It is these free articles which are dispensed.

A support generally indicated at In is provided .of any suitable material and is utilized as a recipient for various operative elements of the invention. This support is composed of a base includ ing a pair ofsubstantially parallel rails l2 and M respectively and a-pair of cross members l6 and l8. A relatively stationary wall 20 is attached to thesaidcro-ssmember l6 for cooperation with j-another wall in retaining the articles to be dis-- jpensed therebetween.

A framegenerally indicated at 22 is supplied forthe cooperation between the wall 20 and the said frame comprises a pair of

legs

24 and 26 respectively which are attached to the said cross member Is by any suitable, conventional means. A header 28 connects the

said legs

24 and 26 and has an aperture therein.

A panel 3!! having an arcuate bottom edge 32 issupplied in the said frame 22 and is supported the said panel may be seen particularly well in Figure 3 wherein there is disclosed a threaded shaft 34. anchored at one end to the. said panel 30 and extending through the aperture in the said header 28". A conventional nut 36 is supplied on the end of the said shaft 34 which when selectively tightened and loosened forms means for regulating the height of the panel relative to the base l0.

Means for resiliently biasing the said panel 30 in a selected direction is provided. This means may be seen particularly well in Figure 1 wherein there is disclosed a conventional leaf spring 38 j anchored to the said panel 30 andhavingthe ends thereof engaging the

arms

24 and 26 respectively. It is readily apparent that by this construction the said panel 30 is constantly urged in a single direction, and a spring 33 is seated on the panel 30 for biasing the header and panel relative :to each other. I

A pair of lates are provided beneath the said cross members l6 and I8 and are pivoted thereto. These plates :2 and 4 respectively are pivoted at their opposite ends, the plate l2 being pivoted by means of the Conventional pivot pin 46 while the plate 44 is pivoted by means of the pivot pin 48.

Reference now to Figure 2 discloses that the said plates 72 and 34 form a seat for the stack of articles maintained between the wall 29 and panel 30.

Manually operable means is provided for moving said

plates

52 and 44 away from each other. This means may be noted as the simplified linkage illustrated in Figure 6 and consisting of the following structure: A bar 50 is provided beneath the said base Hi and a link 52 is pivoted thereto.

This link is also pivoted by means of the pin 54 to the said cross member I6. The terminal portion of the said link 52 is then pivotally associated with the said plate 44 through the medium of another conventional pin 56.

Another link 58 is supplied at the terminal portion of the actuator rod 56 by means of a pivotal connection at 60. This link 58 is pivoted to the plate e2 by means of a pivot pin 62 while the end of the said link 58 is pivotally anchored at 66 to the said cross member I8. Following the arrows indicating direction of travel in Figure 6, it will be appreciated that upon movement of the actuator rod 58 in a single direction the plate 42 will be urged pivotally in the same direction while the plate 44 will be urged pivot-ally in a direction opposite from that oiplate 42. It may now be seen that if any articles are freely supported on the said plates Q2 and A4 respectivelyactuation or" the actuator bar 58 in the direction indicated by the arrows will ermit the free articles resting thereon to be dropped or dispensed.

Means for interconnecting the travel of the said plates 42 and c4 and the travel of the panel 30 is provided. This means is preferably a plurality of links and consists of a pitman 80 con nected with the lever 58 and a second lever 82. This second lever is pivotally associated with the bottom of the said cross member I8 and has a set screw 84 operatively engageable therewith.

The set screw 84 is threadedly received in a bracket 86 which is in turn rigidly secured to the said panel 39. It may now be seen that upon actuation of the

links

52 and 58, the

plates

42 and 44 respectively will be urged in selected directions and the panel 30 will also be urged against the stack of articles by the force of the spring 38. This operation releases the articles maintained on the plates free of the panel 30 and wall 20 yet retains the remainder of the articles between the panel and wall. Upon actuation of the rod 50 in the opposite direction the panel 30 is moved from the articles to allow a selected number to fall on the plates 42 and M respectively in accordance with the adjusted position of the panel 36.

The number of articles to be dispensed is obviously determined by the distance of the panel 30 from the plane of the two

plates

42 and 44 respectively.

In order that the

plates

42 and 44 respectively 2 will be free in their travel and not be impeded by engagement with the pivot pins 1 and the pivotal connection between the link 82 and the cros's'member i8, notches or cutouts 80 are supplied in the said plates to provide clearance. Other obvious and simplified mechanical expedience may obviously be resorted to in connection with the above described structure, without departing from the spirit of the invention.

Accordingly, limitation is sought only in accordance with the scope of the following claims.
