This invention relates to improvements in toothpick dispensing devices and has among itsobjects to provide a new, useful and sanitary device which is adapted to hold a quantity of toothpicks and which is provided with manually operable means for delivering or discharging one toothpick at a time from the storage hopper therein. l It is also an object of the invention to pro vide a delivery 4mechanism for a tooth pick storageihopper which is arranged to receive and discharge only one toothpick during each cycle of operation thereof.
Another object of my invention is found in the provision of a toothpicl feed comprising a `pair of segmental arcuate discharging members provided with longitudinally eX- tending integral ledges adapted upon oscillation in one direction to receive a single toothpick and to discharge said toothpick when oscillated in theopposite direction.
`A further object of my invention is found in the pivotal mounting of such arcuate segmental discharging members and inter-con,A necting means whereby. such members and their integral ledges are always moved in opposite directions.
A still further object is found in the adapta tion of an arcuate segmental pivotally mount ed retaining member having an upstanding longitudinally extending edge and which re taining member is adapted to be loosely mounted over one of said adj acent discharging members and arranged to positively control the gravity discharge of the toothpicks by retaining the toothpick following the one about to be discharged.` The retaining member being resiliently held against movement in one direction `and operatively connected to its adjacent discharging member.
` Still another' object of my invention resides in the provision of a fourth arcuate'segmental member resilientl 1 held in forward position, loosely mounted over the other of said discharging members and arranged to move slightly the pressure of its spring in case a toothpick of abnormal cross section is engaged by the retaining member.
lVith above and other objects in view,
my invention consists in the novel combination,` construction and arrangement of the parts and members shown in the preferred embodiment in the accompanying drawings, described in the following specifications and particularly pointed out in the appended claims.
Referring to the illustrations :d
Fig. 1, is a front elevation of a toothpick dispenser embodying my invention and Fig. 9., is a side elevation thereof with parts broken to show details.
Fig. 3, is a vertical section taken on line 3-3 of Fig. 1, showing the interior thereof7 the feed mechanism being shown in charging position. Y
Fig. 4, is a view similar to that shown in Fig. 3, but with the feed mechanism shownin discharging position.
Fig. 5, is a vertical section taken on line 5-5 of Fig. 3.
Fig. 6, is a cross section taken on line 6-6 of Fig. 3. 4
Fig. 7, is another view similar to that shown in Figs. 3 and 4, but showing the feed mechanism in normal position after receiving the toothpick which isabout to be discharged.
Referring now to the several illustrations, a casing 10 is provided of rectangular cross section having the lower ends 1()A of two opposite walls deflected toward each other to form a discharge spout having an elongated discharge opening 10B. A pair of plates 11 and 12 are provided to form the bottom of a storage hopper 13 for the toothpicks. The plates 11 and 12 also being deflected at their S5 lower ends toward each other to form an elongated discharge opening 13A substantially in vertical alignment above the casing discharge opening 10B. A cover 10C is provided for the open upper end of the casing 10.
The casing 10 may be supported or mounted in any suitable way; I have here shown a curved rod 16 and a base 17 therefor.
A pair of shafts 111 and 15 are provided, which are supported vfor oscillation in the side walls of the casing 10. The ends of these shafts is extended beyond one side of the casing upon which are rigidly mounted intermeshing gear segments 14A and 15A. The
shaft 14; extends beyond the gear segment 14A to receive an operating wheel 14B.
Within the casing 10 and below the hopper discharge opening 13A, I provide a pair of discharging members 18 and 19, rigidly mounted upon respective shafts 1-1 and 15 and oscillatable therewith. The discharging members comprise segmental arcuate walls 18A and 19^ with integral longitudinally extending ledges 18B and 19B respectively at adjacent sides thereof and extending the full length of the walls. The walls 18A and 19A are provided at their ends with downwardly disposed integral ears 18C and'19C which rigidly engage their respective shafts 111 and 15.
A second pair of members 20 and 21 are provided which I term retaining members, as their function is the retaining of the toothpicks following the one engaged by the discharging members. The retaining members 2O and 21 are formed with respectively arcuate segmental walls 20A and 21A which overlay the walls 18A and 19A and which are also provided with downwardly disposed integral ears respectively 20C and 21C. The ears 20C and 21C being however loosely mounted on the shafts 14 and 15.
. The wall 21A is provided with an integral upstanding edge 21B adapted to engage and retain a follower toothpick against the wall 20A during the discharge operation of the members 18 and 19.
The retaining members are held in operative position by means of leaf springs 22.
When the discharging members 18 and 19 are moved to their uppermost position as shown in Fig. 3, the edge 2113 will be raised to permit the follower toothpick to fall upon the ledges 18B and 19B. The movement of the member 21 and its edge 2113 to such upper position is made possible by the provision of the pin 19D mounted within the wall 19A which operates within the slot 21D of the member 21. lVhen the wheel 14B is turned to move the members 18 and 19 upwardly,
the pin 19D will at a certain time reach the end of the slot 21D and cause an oscillation of the member 21 toward the right (as viewed in Figs. 3 and et) against the pressure of spring 22 which is attached thereto and when the hand wheel 14B is released the spring 22 will cause a reverse movement of the member 21 to thereby engage a follower toothpick by the edge 21B and retain same against the wall 20A of the member 20, and during such movement, the members 18 and 19 will be brought into neutral position as shown in Fig. 7, with a toothpick supported on the ledges 18B and 19B in position to be discharged, which may readily be done by movement of the handwheel 14B to cause a downward and separating movement of the ledges 18B and 19B, as shown in Fig. 4. An opposite oscillation of the handwheel 14B will then again bring the parts and members to their positions shown in Fig. 7, where the next or follower toothpick is released for passage onto the ledges 18B and 19B of the discharging members 18 and 19.
It may here be stated that if a toothpick of abnormal oversize cross section should be engaged by the retaining edge 21B, the member 2O being loosely supported on shaft 14 and resiliently held in position, will readily give and thus avoid any inoperation of the discharging members 18 and 19 when moved into discharging position with the pin 19D in the opposite end of the slot 21D pressing against the member 21 to retain the follower toothpick.
An agitator and toothpick straightener is provided in the form of an arcuate plate 23 having an integral side 23A bent angularly to form an arm pivotally and rigidly mounted on the shaft 24 on one end of which is rigidly mounted the operating arm 25. The arm 25 is provided with a slot 25A. The gear segment 14A is provided with an integral extension 14C having a pin 14D which engages within this slot 25A to thereby cause an oscillation of the arm 25 and plate 23 through the masls of toothpicks when the device is operatec.
A cover 26 may be provided over the gear segments 111A and 15A and arm 25.
