My invention comprises a cabinet which I have indicated in its entirety by the reference character A, and a number of dispensing units disposed within the cabinet, two of said units being shown which are designated by the reference characters B and C. These parts will now be described in detail.

The cabinet'A may be of standard construction and in the form illustrated comprises an outer shelllfl. of metal or any other suitable material, and an inner liner ll of similar construction, and of smaller dimensions to provide a space therebetween Whichis filled with a suitable insulating material I2. The shell I 0 and liner H are arrangedto provide a'bottom l3 and lateral walls I4 connected therewith, the uppermost portion of the cabinet having a dispensing opening I5 therein through which access to'the interior of the cabinet may be had. The shell II) has a top l6 secured thereto which is provided with a flange l1 overlying the uppermost end of the shell. Thistop is constructed with an opening l8 somewhat larger than the opening l5 in the cabinet proper. In this opening is set anurnber of frames 19, best shown in detail in Figs. '1 and 2. Where the cabinet is a. relativelylong cabinet, several such frames may be employed, and where a small cabinet is used a' single framemay be utilized. Since these frames and the closures operating in conjunction therewith are identical, only the frame [9 will be described in detail. 7 'j The frame [9 is constructed of sheet metal which is bent to form two rabbets 2| and'22 arranged in elf-set relation with respect to one another and disposed one above the other. The

inner edges of the said frames are welded or portion of the said frames rest upon the top 16 and may be secured thereto in any other suitable manner.

Slidable in the rabbet 22 is a closure 23 which is constructed from a pane of glass 24, having a metal binding 25 extending. about the edges thereof. "The binding 25 is adapted to fit in the rabbet 22 and serves toguide the closure for sliding movement lengthwise along the frame I9. In the rabbet 2| is provided a similar closure 26 which is similarly constructed and is likewise adapted ;to slide from one end of the cabinet to the other. 'The two closures 23 and 26 are of a length slightly greater than onehalf the length of the frame l9 so that the same overlap when in closing position, and when in open position exposeeither half of the space within. the said frame. Handles 21, secured to In one end of the cabinet A, disclosed in Fig. 1 and beneath the frame I9, are disposed thetwo dispensing units B and C, as previously stated. In addition a rack 28 is also provided which consists of vertical rods 29 connected to suitable:

cross-rods 3| which divide the rack into four compartments 32, 33, 34 and 35. This rack is fixed in position within the interiorof the cabi net and serves to hold articles-which are not readily adapted to be dispensed from thedispensing units B and C.

Inasmuch as both of the dispensing units B and C are identical in construction, only the unit y B will be described in detail. Each of thedispensing units has a number of separate dispensing devices independently operable, wherebya the dispensing devices 5|, 52. 53and 54in which the articles to be dispensed are. separately con-. tained and fromwhichthe' same are dispensed. I This frame structure comprises two transversely disposed bars 361and 31 which extend complete-1 ly across the cabinet. Attached to these two bars are a number of uprights 38 which are formed ed or otherwise secured ;to the said bars 36-and .39 with earsH-bent outwardly therefrom and weld- 31'. The uprights 38are arranged in pairs which are closely positionedto provide grooves 42 therebetween and form'guides for guiding the supports for the articles to be dispensed for vertical movement, as-will be hereinafter more fully described. As'will be noted in the drawing there is one pair of uprights 38 for each of the dis pensing devices 5|, '52, 53 and 54. Extending between the pairs of uprights 38, near the upper portions of the same and. below the bars 36 and 3,1 are transverse rods 43 which tie the same together. Depending from these transverse rods are other uprights 39 which lie in the same planes; as'thefl uprights 39; 'All' of, the, up-

rightsare connected. together at their lower.

45 which extend between :the rods 44. The rods 45 are disposed at .the'ends of the unit and at Fig. 2. By-means of-these lugs the trays are supequally spacedlocalities intermediate the ends of the unit. In addition to the uprights 38 and 39, uprights 46 are provided at the ends of the unit and other uprights 41 are employed, which uprights extend upwardly from 1 the cross-rods 45 and which-are secured thereto. The uprights 46 and 47 aresecured at their upper ,ends to cross-rods 48 which are disposed directly above the rods 45-and which are themselves secured to the transverse rods 43. The uprights 41 divide the; space within the interior of the unit into provided two eyes 56 which-are attached to the lowermost portions of certain of the uprights 38. These eyes have received in them'pins 51 bent downwardly from brackets 58, secured to the corresponding uprights 41 of the unit C. Other pins attached to the brackets 58 and spaced from the pins 51 engage the eyes 56 exteriorly. This .mo'st portion of the cabinet. Extending across the juxtaposed bars 36 of the two units B and C is a plate 58' which is secured to said bars by means of screws 59 extending through said plate and threaded into the said bars. A similar plate 6|, at the free end of the unit B, is attached to the bar'31 and conceals the ears 4| and gives the upper surface of the frame structure the same appearance at both sides. In this manner the various frame structures are held attached to one another and in proper position within the cabinet. While I have shown only two units in the space beneaththe frame l9, it will readily be comprehended that the: rack 28 may be dispensed'with in other sections of the cabinet and the entire space filled with dispensing units.

Inasmuch as all of the dispensing devices are identical only the dispensing device 54 will be described in detail, which is best shown in Figs. 2 and 3. This dispensing device comprises a support 62 in the form of a tray having a bottom 63 and spaced side walls 64. This tray serves asa shelf for supportingthe articles to be dispensed. In connection with the dispensing device 5|, packagesindicated at 65, are employed which rest upon the support or tray 62 and which are of an appreciable height. The two dispensing devices 52-and 53 have been illustrated as .having packagesgor. boxes 66 and '61 mounted thereon of lesser height than the boxes or packages 65. The dispensing device 54, for the sake of illustration, has'been shown as having no articlesplaced thereon and being disposed in its uppermost position. Extending across the bottom 63 of the support or tray 62 is a cross-rod 68 which is welded thereto. Thisrod has the ends thereof projecting outwardly beyond the sides 64 of said tray to form lugs 69 which are adapted to slide in the grooves 42 formed between the uprights 38. These lugs are best shown in connection with the dispensing device 54 in Fig. 3 and with the dispensing devices 5| and 52 of ported for vertical movement between the guides of the frame structure 55, whereby the said trays and the articles contained thereon may be raised. To prevent tilting of the trays guide fingers 1| are employed which are welded to the lugs 69 and to the flanges 64 of tray 62. These fingers extend upwardly between the uprights 38 and are disposed in the grooves 42. ,The fingers 1| thus-hold the trays in proper position.

, For the purpose of elevating the trays or the support. 62, two lifts 12 and 13 are employed which are attached to the two transverse bars 36 and 31. Inasmuch as both of these lifts are identical in construction; onlythe lift 12 will be described which is shown in detail in Fig. 4. This lift comprises a case 15 which has a semicylindrical portion16 adapted to be telescoped into a rectangular portion 11. The rectangular portion is provided with a flange 18 by means of which the. case may be bolted to the bar '36 through machine screws 19. The two parts of thecase are held together in any suitable mancase 15 is provided a pulley 82 which is journaled on the pintle 8|. This pulley is hollow and has disposed within the same a spiral spring 83 which is attached at one end to the pintle 8| and at the other end to the rim 84 of the said pulley. The pintle 8| may be welded or otherwise secured to the case 15 so that rotation thereof is prevented. Encircling the rim 84 of the pulley 82 is a flexible metal ribbon 85 which is secured at one end to the said rim and which projects outwardly through the case 15 at one side of the same. This ribbon is formed with a loop 86 at the outer end thereof which extends about the lug 69 of the tray 62. The spring 83 is normally tensioned sufliciently to hold the tray in its uppermost position and, when the tray is lowered along the guides 38, the said spring becomes further tensioned and is capable of raising the loaded tray upwardly.

Extending upwardly from the cross-rods 48 are arms 81 which have formed on the ends thereof stops 88 over-reaching the bottom 63 of the tray 62. These stops are adapted to engage the packages, articles or boxes placed upon the trays and hold the uppermost article or package of the stack at the desired dispensing elevation. Thus each of the uppermost articles or packages is available to be dispensed.

In operation the packages or articles to be dispensed are placed one upon the other in the respective compartments to form a stack of articles, the lowermost article resting upon the tray of the dispensing device and the uppermost article engaging the stop thereof. As the packages are accumulated in the stack, the tray is lowered until the same reaches the bottom of the cabinet. When the stack is released the stops 88 engage the uppermost package at one edge thereof, and hold the stack from further upward movement. When the articles are to be dispensed the uppermost article is grasped by placing the finger between the stacks of articles and raising the article at the edge opposite the stop 88 soas to disengage the article from the stop 88 and release the same. Thereupon the article may be removed from the compartment 30. As soon as the article is out of the way the springs 83 raise the support or tray 62 and bring the next article in the stack into engagement with the stops 88. This continues until all of the articles have been removed from the compartment, whereupon the support takes the position of support 62 of the dispensing device 54 shown in Fig. 2. As the articles are raised by the various dispensing devices, the same are confined to ver' tical movement by the various uprights forming the various compartments 38 in which the dispensing devices operate.

The advantages of my invention are manifest.--

The dispensing cabinet is extremely simple in construction and practical in operation. The articles to be dispensed are all at the uppermost level of the cabinet where the same are visible through the glass closures of the cabinet. The

articles are easily reached and easily removed from the stacks. So long as there are any articles in the stacks, the cabinet has the appearance of being completely filled. By means of the particular construction of the lifts employed, the articles are raised without appreciable loss of height in the cabinet, thus giving maximum capacity. The dispensing device and theframe structures in which the same operate are constructed in a manner to make the dispensing units extremely sanitary. The dispensing units are-readily removable to permit of cleaning and repair when required. While I have shown no refrigeration within the cabinet, it will be readily comprehended that suitable refrigeration coils may be attached to the walls of the liner II and disposed within the space formed between the said liner and shell I0. Such construction being well known in the art, has not been shown in this application. If desired, refrigerated air may also be circulated through the cabinet to maintain the products dispensed at the proper temperature. While the cabinet is particularly desirable for frozen food, nevertheless the same may be used for other articles where refrigeration is not required.
