Denmark November 19, 1941 Section 1, Public Law 690, August 8, 1946 Patent expires November 19, 19.61
The present invention relates to a commodity delivery device for coin-freed apparatus.
Commodity delivery devices are already known in which a pressure foot rests upon the uppermost package of a pile of commodity packages, and which pressure foot is connectedto a guide that may slide freely along a column. This construction, however, has the essential drawback that during the ejection of the uppermost package, the guide is not held securely but constantly has a tendency to slide downwards, so that the pressure effectuated on the next package inthe pile will be such that this package is moved from its position within the commodity compartment.
The object of the present invention is to provide means for overcoming this drawback in a commodity delivery device of a coin-freed apparatus, and according to the invention thisobje'ct is attained by means of a bellzcrank lever pivoted on a slidable platform, the said bell crank lever being actuated by means of a coin-freed eiectromagnet in such a manner that it ejects the uppermost package of a pile of commodity packages, and at the same time actuates means for locking a ratchet wheel mounted within an extending part of the platform on a fixed threaded spindle, so that the platform is prevented from sliding downwardly. Upon the bell crank lever being released by the electromagnet, it returns by means of spring pressure to its initial position, at the same time releasing the means locking the ratchet wheel that may thus rotate on the fixed threaded spindle to allow the platform to slide down to a position for ejecting the next package in the pile of commodity packages.
The invention is described in detail in the iollowing description and the accompanying drawing, in which Figs. 1, 2 and 3 illustrate a device accordin to the invention seen in top elevation, in front elevation, and in side elevation respectively. Fig. 4 is a sectional view on line aa in Fig. 1, and Fig. 5 is a sectional View on line b-b in Fig. 2. I
l and 2 indicate the upper and the lower plates of a commodity container. These ends are assembled means of spacing rods 3. Within the container there is placed a stack of commodity packages 5, which in Figs. 3 and 4 are indicated by dotted lines. Slidable on the spacing rods 3 there is a platform 8 which carries an upwardly extending fixed arm 9. The platform 8 is slidable by means of guide members 23 slidable on the rods 3. By means of a pivot Ill on the arm there is rotatably mounted a bell crank lever H, which at the extreme end of the one 3 Claims. (Cl. 312-63) arm has a plate l2 that extends behind the uppermost package 1. Furthermore this arm has at its lower end a branch 13 with a pressure foot M that rests with its foot upon the uppermost package 1 in the pile of packages. To the other arm of the bell crank lever there is attached a cord [8 that is connected to an electromagnet not shown in the drawing. The'platform 8 is provided with a rearwardly projecting U-shaped extension l5 providing a space within the bend for a horizontally disposed ratchet wheel 16. This ratchet wheel is internally threaded so that it may be screwed on to a threaded spindle ll rigidly disposed between the ends I and 2 of the commodity container. The thread of the spindle is such that the ratchet Wheel is not self-lockiiig. The ratchet wheel I 6 may be locked against rotation by means of a pawl 26 mounted on a pivot l 9 on the extension I 5 in such a manner that it may engage the teeth of the ratchet wheel.
On the bell crank lever there is a lug 22 that nore mally holds the pawl 20 out of engagement with the ratchet wheel 16.
The device operates in the following manner; F When the coin-freed apparatus comprising the commodity delivery device is actuated by the insertion of a coin, an electric circuit is closed through an electromagnet, not shown in the drawing, and a pull is exerted on the cord 18. The bell crank lever H to which the cord I 8 is connected is rotated on its pivot 10, and its depending arm with the plate l2 ejects the uppermost package out of the commodity container through an outlet opening not shown in the drawing. By this movement of the lever, the lug 22 releases the pawl 20 which by its weight drops to engage the teeth of the ratchet wheel l6, and thus prevents this wheel from rotating on the fixed spindle l'l. Thus the platform 8 cannot slide downwards as long as the bell crank lever is in its ejecting position on account of the extension containing the ratchet Wheel. When the pull of the cord 18 ceases, the bell crank lever II will return to its inactive position by the actuation of a spring 2 I. During this return movement of the bell crank lever the lug 22 will again raise the pawl 20 and thus release the ratchet wheel l6, which rotates on the spindle owing to the weight of the platform, which thus slides downwards until the pressure foot 14 abuts the now uppermost commodity package in the pile.
I declare that what I claim is:
1. In an article delivery device for a coin-freed apparatus, the combination of a number of vertical spacing rods between two horizontal end plates, 2. platform slidable on the spacing rods, an upwardly extending arm attached to the platform, a spring actuated bell crank lever pivoted to the upper end of the said arm and adapted to be actuated out of itsinactive position, a ver tical plate member attached to the lower end of one arm of the bell crank lever and so disposed adjacent the top of a stack of articles on the platform as to eject the uppermost article of a stack of articles when the bell crank lever is ac tuated, a forwardly and. downwardly extending presser foot attached to the lower end of the other arm of the bell crank lever and resting u on the uppermost article in the stack, a rearwardly projecting U-shaped extension on the platform. a vertical threaded spindle rigidly fixed to the end plates and passing through the, said extension, an internally threaded ratchet wheel mounted on the spindle and disposed within the extension, a pawl pivoted on the extension and disdisposed to engaged and lock the ratchet wheel during the actuation of the bell crank lever while ejecting the uppermost article, and a lug on the bell crank lever for raising the pawl out of engagement with the ratchet Wheel upon the return movement of the bell crank lever to its inactive position to permit said platform to be lowered and the presser foot of the bell crank lever to contact the uppermost article of the stack.
2., In an article delivery device for a coin-freed apparatus; the combination of a number of vertical spacing rods between two horizontal end plates, a platform slidable on the spacing rods.- a bell crank lever pivotally mounted on the platform and adapted to be actuated out of its inactive position, a member secured to the. lever in position to eject the uppermost article of a stack of articles when the lever is actuated, a presser foot on the lower end of the lever and adapted to rest upon the uppermost article inthe stack. a rearwardly projecting U-shaped extension on the platform, a vertical threaded spindle rigidly fixed to the end plates and passing through the extension, an. internally threaded ratchet wheel mounted on the spindle and disposed within the extension, a pawl pivoted on the extension and disposed to engage and lock that ratchet Wheel during the actuation of the lever while ejecting the uppermost article, and a lug on the lever for raising. the pawl out of engagement with the ratchet wheel upon the return of the lever to its inactive position to permit said platform to be lowered and the presser foot of the bell crank lever to contact the uppermost article of the stack.
3. In an article delivery device for a coin-freed apparatus, the combination of a number of vertical spacing rods between two horizontal end plates, a platform slidable on the spacing rods, a bellcranklever pivotally mounted on the platform and adapted to be actuated out of its inactive position, a member secured to the lever in position to eject the uppermost article of a stack of articles when the lever is actuated, a presser foot' on the lower end of the lever and adapted to rest upon the uppermost article in the stack, an extension on the platform, a vertical threaded spindle rigidlyfixed to the end plates and passing through the extension, an internally threaded ratchet wheel mounted on the spindle and disposed within the extension, a pawl pivoted on the extension and disposed to engage and lock the ratchet wheel during the actuation of the lever while ejecting the uppermost article, and a lug on the lever for raising the pawl out of engagement with the ratchet wheel upon the return movement of the lever to its inactive position to permit said; platform to be lowered and the presser foot of the bell crank lever to contact the uppermost article of the stack.
