WILLIAM C. CUTLER, OF GLENDALE, CALIFORI TIA, ASSIGNOR, BY MESNE ASSIGN- MENTS, T0 SELECTIVE AUTOMATIC MANUFACTURING CORPORATION, LOS ANGELES, CALIFORNIA, A CORPORATION OF CALIFORNIA.
Application filed November 28, 1925. Serial No. 72,050.
The present invention relates to vending machines and has for its principal object the provision of a selective vending machine of large capacity.
Another object of the invention is to provide a vending machine which will offer a wide choice of articles, with means whereby the entire contents of the machine may be reviewed by a prospective purchaser.
' Another object of the invention is to pro- .vide a vending machine of the character described, which is capable of being replenished while the machine is in actual operation, unknown to the operator.
It Will be understood in the consideration of this invention that selective vending machines selling boxed articles such as sandwiches and pies, are subjectto heavy patronage at the noon hour and even a large capacity machine will soon be emptied under such conditions. It is therefore another object of the invention to provide a machine capable of serving, or being operated by, hundreds of persons in a very short interval of time.
Another object is to provide a vending apparatus suitable for automatic cafeterias and the like.
Another object of the invention is to provide a simple means for holding individual articles in large number in such manner that any article may be brought into registration with the vending mechanism and the delivery chute.
Still other objects and advantages of my invention will appear hereinafter.
I have illustrated one practical embodiment of my invention by the accompanying drawings in which;
Figure 1 is a perspective view of the said embodiment as it appears to a prospective purchaser.
Figure 2 is a view in vertical section thereof seen on a line 22 of Fig. 1.
Figure 3 is a view in section seen on a line 33 of Fig. 2.
Figure 4 is a view in section seen on a line 4-4 of Fig. 3.
, Figure 5 is a View in perspective of the article carrying means.
n carrying out my invention in the present embodiment I employ two spaced sprocket chains 10 and 11 respectively, running over spaced sprocket wheels 12 and 13 respectively. Said sprocket wheels are fixed to a drive shaft 14 adapted to be rotated by a crank 15. The chains are composed of intermediate links 16 and spaced alternate links 17 arranged in pairs to provide intermediate spaces 18 for the receipt of the teeth 19 of the sprocket wheels. The innermost one of each pair of alternate links, on each chain. is provided with a U-shaped clip 20 suitably secured thereto. The clips on one chain are directly opposed to the corresponding clips on the other chain; the open part of each clip facing the open part of the corresponding clips.
Each pair of opposed clips is adapted to serve to hold an article such as a box carton 21, containing a sandwich, pie, candy bar, or any other article (not shown). The clips are open at each end so that the ends of the boxes are visible and may hold a label to indicate the contents of the box.
The sprocket wheels and shaft, as well as the links adjacent the sprocket wheels, are housed in a suitable casing 22 having glass covered side panels 23 thru which the ends of the clips may be seen; said clips are provided with letters such as A, B, etc., to designate them and these letters are visible thru the glass panels. The arched wall 22 of the casing'is also provided with a sight opening 25 thru which theendsof the boxes may be seen as they pass said opening. By turning the crank, the sprocket wheels will be rotated and the chains will move together and successively display the boxes to the view of one looking thru the sight opening 25. Thus a prospective buyer may turn the crank until the desired article is in view thru the sight opening. Each box may contain a number (not shown) opposite the label, so that the box can be identified.
The arched wall is provided with an upstanding delivery chute 26. A patron having located the desired article, notes the number thereof and then turns the crank slightly further to bring that number of clip into registration With the delivery chute. The clips hold the articles frictionally against gravity but any box may be pushed out of place and up thru the chute by an ejecting member, such as 27. Said member is connected by levers such as 28 to a foot pedal 29. When the pedal is depressed the ejector is forced upwardly to drive a box from its clips thru the delivery chute. When the ejector raises the box to a suitable height it may be reached by the purchaser. To one sprocket wheel there is fixed a star wheel 30 having notches 31, onetor each set of clips. A centering bar 32 is provided which rides vertically with the ejector; said bar being held and guided by pins 82' ridingin slots The bar carries a lug s4 and the ejector carries another lug 35, between which there is provided a compression spring 36. Thus when the ejector starts to rise the centering bar is raised by the spring. The pointed end 37 of the bar then enters the nearest notch and moves the sprocket wheel slightly to bring the nearest box into registration with the delivery chute. Incidentally, said centering bar holds the entire assembly of parts locked against movement until it is again retracted. lVhile the ejector is traveling further upward the spring undergoes further compression. When the ejector is allowed to descend after ejecting a box, it returns practically to normal position before the spring is extended far enough to draw the centering bar back to normal.
It will be apparent now that any article carried by the chain may be selected, moved to proper position and ejected, by proper use of the crank and foot pedal. Using the foot pedal leaves both hands free to insert a coin in the coin slot 40, and to co-incidentally reach for the package issuing from the de livery chute. It is understood that the coin slot leads to suitable coin controlled means (not shown) said means preventing the foot pedal from being effective on the ejector unless a proper coin has been inserted in the slot.
The contents of the machine may be re v mviewe'd, and the selected article moved into 'registr'ationj with the delivery-chute before the coinis inserted.
In conformance with one of the salient fea- Qtures of this invention, the chains may be made'as long as desired, according to the capacity required.
In the embodiment shown the casing is mounted on a counter 43 Well above the floor 44. The floor may be that of a restaurant, or other place where it is desired to sell the contents of the machine without requiring the services of a clerk. The counter encloses and obscures the chains and they are continued downward below the counter into a basement, for example, where they run over idler sprockets 45. The machine may be replenished from the basement whenever required. In a large, automatic cafeteria several machines, each of large capacity, may
readily be kept filled by one attendant. New cartons may be placed in the clips even while thechains are in motion, so that continued service is not interfered with. The coins inserted in the coin slot may either go to a suitable releasing mechanism, or the ejector may be released by an attendant who inspects each coin coming thru the coin slot, and releases the ejector once only for each legitimate coin of proper denomination received. Such mechanisms are employed at toll gates in railway stations and the like and are well enough understood that they do not require description herein.
The chains. in ascending, pass between two guides 40 which. serve to adjust any boxes which may protrude unduly from their clips. Should an attendant hastily insert a box in a pair of clips while they are moving, the guides will tend to move the box eventually to correct position in the clips so that the machine cannot bccome jammed by a protruding box.
The operation of the machine and its parts is quite apparent from the foregoing. If the machine were to contain 100 boxes for in stance, including 10 separate brands or kinds of articles, the articles could be arranged in groups of ten different kinds. Thus a prospective purchaser would never have to move more than 10 boxes by the sight opening before he located the brand which he desired. Having selected the article thru the aid of the indicating letters and labels, seen thru the sight openings, the prospective purchaser inserts a coin in the coin chute. At about the same instant he steps on the foot'pedal and uses the hand, not employed in inserting the coin, to reach for the expected box which is to be delivered via the upstanding chute. If he has stopped the chains in such position that the desired box is not accurately alined with the chute, the first movement of the centering bar will aline said box properly with said chute. Continued depression of the pedal moves the ejector up to the delivery chute, forcing the selected box ahead of it.
