9 Claims;

This invention relates to improvements in dispensing apparatus and has for one of its objects to provide an improved apparatus of simple and practical design suitable for use in cafeterias and 5 the like, and by means of which articles such as knives and other eating utensils may be dispensed to patrons.

Another object is to control thedispensing of articles from the apparatus so that the same it will be individually discharged therefrom by the operation of an improved mechanism which releases one article at a time from a stack and discharges said article when a plunger member is actuated.

The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawings which illustrate a preferred embodiment of the inventive idea.

In the drawings:

Figure 1 is a perspective view of the apparatus constructed in accordance with the invention.

Figure 2 is a vertical longitudinal section therethrough illustrating the position of the parts at the time an article, such as a knife, has been discharged from the casing of the apparatus to a position where it may be completely withdrawn from the casing, said position also being that of the normal condition of the apparatus prior to a release of an article from the receptacle and hopper in which such articles are stored.

Figure 3 is a horizontal section through the casing of the apparatus, showing the operating mechanism in plan view.

Figure 4 is a vertical transverse section on the line 4-4 of Figure 2 illustrating the normal position of the article-supporting members.

Figure 5 is a similar View showing the operated position of said members and the position 40 of the lowermost article in the stack after its release by the operation of said supporting members, and

Figure 6 is a vertical transverse section on the line 8-6 of Figure 2.

Referring more particularly to the accompany ing drawings the apparatus is shown as comprising a base I supporting a, casing II having a discharge outlet I 2 in the front wall thereof and being further provided in its top I3 with a longitudinal opening I4 extending the length of said top. Disposed above the top l3 and aligned with said opening is a removable article-containing receptacle I of sufficient size and dimensions to receive a supply of articles such as the knives I6 in stacked formation. The receptacle I5 is mounted in position by a sliding engagement with the top of the casing and for this purpose said top and the receptacle are provided with a tongue and groove formation as indicated at IT. Preparatory to mounting the filled receptacle I5 in its inverted position on the casing, a removable cover, indicated in dotted lines at I8 in Figure 4, is slid into the groove of the receptacle so as to retain the knives in position therein when the receptacle is inverted and being mounted in its position on the casing. Upon completion of this operation the cover I8 is removed so as to permit the knives within the receptacle to drop into a hopper in the casing. This hopper consists of the front and rear members I9 and secured within the casing and both aligned with the opening I4 in the top thereof. The front member I9 has a constricted lower end 2| to receive the handles of the two lowermost knives I6, as viewed in Figure 4, while the rear member 20 is provided with a forwardly inclined wall 22 which supports the free end of the lowermost knife, as seen in dotted lines in Figure 2.

To maintain the handle ends of the knives in position for individual release and subsequent discharge from the casing, supporting means are provided adjacent the front of the casing and in cooperation with the hopper member I9, said means consisting of two oscillatory supporting members 23 arranged on opposite sides of the lower end 2| of said hopper member. Each member 23 is in the form of a sleeeve loosely mounted for oscillatory movement upon a standam 24 and provided adjacent its upper end with a supporting lug or shoulder 25. Normally, the two lugs 25 of the members 23 extend inwardly toward each other and beneath the lower end of the hopper I9 so that the handle of the lowermost knife I6 rests thereon, thereby supporting the stack of knives within the hopper and recep'tacle I 5. When the members 23 are oscillated in a manner to appear in the course of the description, the lugs 25 are swung aside to positions where they will no longer support the lowermost knife and the latter will be permitted to drop from the hopper. In order to prevent the release of more than one knife at a time, when said members 23 are oscillated, further means are provided on said members for engaging and supporting the next lowermost knife handle until the members 23 are restored to the normal positions wherein the lugs 25 will again be projected beneath the last-named knife. Such further means comprise two laterally extending flanges 26 at the upper end of each of the members 23 and spaced apart a sufficient distance to receive one edge of the knife handle therebetween. Said flanges 26 extend circumferentially about each member 23 for a greater portion thereof but at 2'! (Figure 3) directly above ,the lugs 25 the flanges terminate in straight edges so as not to engage the handle of the next lowermost knife when the members 23 are in their normal position; However, when said members 23 are oscillated to withdraw the lugs 25 from beneath the lowermost knife, the flanges 26 will be turned to engage on opposite sides of the next lowermost knife before the lowermost knife is released and the former knife will then be held from dropping. Upon the return movement of the members 23 after the release of the lowermost knife, the lugs 25 will again be swung into supporting position so that the then lowermost knife in the stack will fall upon said lugs after the flanges 26 have been disengaged from said knife and the parts will then be in position for another operation.

To accomplish the release of a knife by the operation of the members 23 as just described, there is preferably provided on operating mechanism consisting of a plunger 21 extending longitudinally of the casing ii and slidably mounted in suitable bearings adjacent one side of said casing, with the front end of said plunger projecting through the front wall of the casing so that it may be forced inwardly by a person desiring one of the articles. The plunger 21 is yieldably held in its projected or normal position by the spring 28 coiled about said plunger and interposed between one of its bearings and a collar 29 secured on the plunger. Adjacent the forward end of the plunger and at a point within the casing, said plunger is provided with a slot 30 to receive the free end of an arm 3| carried by the adjacent supporting member 23 so that when said plunger is forced inwardly the arm 3| will be swung therewith to turn the member 23 adjacent thereto in the direction of the arrow indicated in Figure 3 and thereby withdraw the lug 25 from beneath the lowermost knife. This operation of the plunger is also utilized to operate the other supporting member 23 through the medium of a rocker arm 32 adjacent the rear end of the casing, one end of said arm projecting into the opening 33 in the rear end of the rod 21 while the other end of said arm engages in a similar opening 34 in the rear end of a sliding rod 35 supported in parallel relation to the plunger 21. Adjacent the front end of the rod 35 the same is provided with an opening 36 to receive the free end of an arm 31 carried by the other supporting member 23 and adapted to turn said member in the direction indicated by the arrow in Figure 3, when the plunger 21 is forced inwardly, so as to withdraw the lug 25 of said other member 23 from engagement with the lowermost knife and engage the flanges 26 with the next lowermost knife. After the release of the knife as described and withdrawal of pressure upon the plunger 21, the latter is projected outwardly to its normal position under the influence of the spring 28 and this movement of said plunger effects a reversal of the turning movement of the supporting members 23 so that the same will be restored to their normal position. This last-named movement of the plunger 21 is also utilized, as will appear from the following description, to effect the discharge of the released knife to the dotted line position shown in Figure 2 so that it may be withdrawn from the casing.

When a knife is released from the stack as described the handle end thereof falls upon an idler roller 38 supported upon the bottom of the casing directly behind the members 23. Said roller 38 is preferably tapered from its ends toward the middle thereof and engages in the usual groove formed between the inner ends of the knife handle and blade, as indicated in Figure 2, when the knife has been projected to its discharged position, the engagement of the roller in said groove acting as a stop to limit the discharging movement of the knfe.

At the same time that the handle of the knife is dropped to its position upon the roller 38 the inclined wall 22 of the rear hopper member 2!] acts to guide the free end of the blade of the knife forwardly so that said end falls into an abutment 39 of the carriage which has been previously moved rearwardly from its normal article discharging position shown in full lines in Figure 2 to the dotted line or article receiving position therein under the influence of the inward movement of the plunger 2'! as will be presently described. Said carriage, which includes the abutment 38, further comprises an elongated plate 40 slidably mounted in a trackway 4i sup ported upon the base l0. Adjacent the forward end of the plate 40 the same has a pin and slot connection with one end of a lever 42 the other end of which is pivoted to the bottom of the casing at 43. The pivot of said lever also carries an arm 44 above the lever 42 and the free end of said arm projects into an opening 45 formed in the plunger 21 so that as the latter is operated the arm 44 and the lever 42 will be swung to move the carriage rearwardly from its discharging position to the dotted line position of Figure 2 when the plunger is depressed, and to move said carriage forwardly from its receiving position when the plunger is restored to its normal position under the influence of the spring 28. Thus, as previously referred to, when the plunger 21 is pushed inwardly the carriage with its abutment 39 reaches the dotted line position of Figure 2 and at this time the free end of the blade of the knife drops into said abutment while at the same time an intermediate portion of the handle of said knife falls upon the roller 38.

Then when the plunger is is released the carriage moves forwardly to project the handle end of the. knife through the discharge opening l2 where the intermediate portion of the handle rests upon a roller 46 while the inner end of said handle rests upon the roller 38. The knife may then be lifted and withdrawn from the casing and the apparatus is then ready for another operation.
