Claim.
This invention relates to apparatus for storing and dispensing stacked articles. More particularly, it relates to a device for housing and dispensing stacked articles of uniform size and weight, such as plates or other dishes or the like, said device being a specific form of the invention illustrated and described in my copending application Serial No. 130,787, filed March 13, 1937, of which this application is a division.
The invention has among its objects, the provision of a device for housing and dispensing stacked articles so that the uppermost unit of the stack is always presented for use at a predetermined convenient position and the underlying units of the stack are housed or held in a protected position for automatic upward feedin upon the removal of the uppermost article of the stack, the provision of a time, space and breakage saving unit, and a device which obviates the necessity of stopping, reaching or lifting stacks of articles from place to place when in use.
In carrying out the objects of the invention there is provided a storing and dispensing unit including a vertical housing and calibrated spring motivated load handling carrier so arranged that a stack of articles on the carrier is so positioned in loading and unloading that the uppermost article of the stack is brought to predetermined height or position convenient for removal at the top of the unit. The apparatus will be better understood from the following detailed description of the invention having reference to the accompanying drawings wherein like reference numerals have been used to represent like parts throughout the several views, and in which- Fig. 1 is a perspective view of an embodiment of the invention adapted to hold and feed a stack of plates.
Fig. 2 is a top plan view partly in section of the device of Fig. 1.
Figs. 3, 4, 5 and 6, are respective sectional elevation views taken on the lines 3-4, 4-4, 5-5 and 6-4 of Fig. 2, looking in the direction of the respective arrows.
Referring to the drawings, wherein an embodiment of the invention is shown in the form of a mobile service unit arranged for individual use or use in conjunction with a service counter or the like, I indicates a rectangular casing or housing having a flat top portion 2 with a plurality of apertures 3 for passage therethrough of stacked articles. The casing can be of any suitable construction and encloses a supporting framework movable from place to place.
supports in suitable bearings near its top the rotatable shaft 6 carrying at one end thereof sprocket I over which passes the endless driving chain 8 which at its lower turn passes under sprocket 9 mounted in the lower shaft lli rotatably supported in suitablebearings near the bottom of the framework. The lower shaft l0 carries rotatable therewith drum II with which a plurality of sprocket chains I2 are connected at their respective ends. Each sprocket chain 12 at its other end connects to the lower end of a respective tension spring l3 whose upper end is connected to an eye bolt l4 passing through a respective opening in angle bar I5 of the framework where a wing nut IE or equivalent serves both for holding the eye bolt and for effecting adjustments of the tension on its respective spring. The arrangement constitutes a motivating means for shaft 6, the energy of said springs being transmitted so as to tend to rotate shaft 6 in one direction and oppose its reverse rotation.
The shaft 8 carries adjacent one end thereof sprocket I 6 over which is trained an endless sprocket chain 11, said chain passing in a horizontal reach over'an aligned sprocket I8 mounted at the top of the frame, and thence downwardly in a vertical reach to and around sprocket l9 and back up to sprocket IS. The sprocket I9 is rotatably mounted at the bottom of said framework in vertical alignment with sprocket l8 so that the reach of said chain I! therebetween moves in a vertical direction.
7 The shaft 6 also carries adjacent sprocket 1 separate sprockets 20 and 2|. Sprocket 20 cooperates with and supports the upper turn of.the endless sprocket chain 22 which extends vertically downward and, at its lower turn, around sprocket 23 which is rotatably mounted on said framework 4 at the bottom thereof and in a position directly below sprocket 20. Sprocket 2| carries a sprock- .et chain 24 which in one direction extends downwardly to and connects with one end of a metal tape 25 whose other end is wound around a drum 26 which has a steep spring (not shown) which tends to turn said drum 26 in a direction to wind said tape thereabout and thereby hold said chain 24 taut and in engaging relation with said sprocket 2|. In the other direction, the chain 24 extends horizontally to the opposite side of said framework where it passes over the free moving sprocket 21 and then downwardly to a T-shaped carrier frame 28, where its end is fastened to an outstanding lug 29 on one end of the cross bar 30 of the carrier. The opposite end 3! of said cross bar is connected to a link of chain 22, and the longitudinal bar of said T-shaped carrier frame 28 connects with a link on said endless sprocket chain [1. The carrier frame is thus supported at three points in a level horizontal position underlying the apertures in the top of the casing.
The longitudinal portion or bar has fixed V thereto a pair of spaced apart circular racks 33 above which are the correspondingly shaped openings 3 in the top of the casing. A stack of plates 34 on each of said racks 33 extends upwardly through a respective opening 3 in the top of the casing and is guided in up and down movement with said carrier by three spaced vertical rods 35 fixed at their upper and lower ends to said framework by the bracket arms 36. A downwardly depending flange member or guide 31 is provided at the top portion, apertures to guide the stacked articles passing through the top openings.
A gauge for indicating thevolume of stacked articles on the carrier isarranged so as to be visible through a window or sight aperture 38 in the top of the casing. In the illustrated emcating marks which register with the window 38.
The indicator member is made to move across the window as the shaft 6 and screw thereon is rotated, and in such movement is held against .-While the invention is described in connection with a specific embodimentpit'is to be understood that'the words used are words of descrip-v tion rather than of limitation, and that practice of the invention within thescope of theappended claims may be resorted to without i departing from the true scope and spirit of the invention in all its aspects.
