Referring to the drawings, the improved toothpick holder and dispenser is designated generally at 11. The device 11 comprises a receptacle 12 which is generally rectangular in shape and is formed with an inclined or sloping bottom wall 13, as shown in Figure 2, the receptacle being adapted to support therein a plurality of toothpicks arranged so that their axes are parallel to each other and transverse of the sloping bottom wall 13 and to feed the toothpicks by gravity towards the lowermost portion thereof through a discharge space 14 beneath the bottom edge 15 of a depending vertical transverse partition wall 16 secured in the receptacle. v

The receptacle 12 comprises the vertical rear end wall 17, the vertical transverse front wall 18, and the respective

vertical side walls

19 and 20, defining a rectangular vertical notch 24, as shown to fit on the top edges of the

side walls

19 and 20 and is provided with a vertical rear marginal flange 22 which is receivable in a transversely extending vertical seat 23 formed on the top margin of the rear wall 17. The flange 22 is formed at its intermediate portion with a in Figure 4, which is engageable over an outwardly projecting stud 25 on which a looking nut 26 is threadedly engaged, whereby the flange 22 is tightly gripped and clamped in the seat 23 when the nut 26 is tightened. The forward marginal portion of the cover 21 is receivable in a transversely extending edge of the seat member27 ceives the forward marginal is rigidly secured at its rear flange 1 wall 18 is formed with a seat 27 formed on the rear marginal portion of a horizontal top wall segment 28 rigidly secured on the forward portion of the receptacle, the cover 21 being provided with a hook-like lug member 29 engageable beneath the so that the seat member r e portion'of cover 21 therein and the hook-like lug member 29 therebeneath, as shown in Figure 2. As is readily apparent from Figure 2, the cover 21 is lockingly engaged in the

seat member

27 and 22 in the seat 23 when the nut 26 is tightened.

As shown in Figure 2 a space is defined between the upper portion of front wall 18 and the depending partition member 16, said space being shown at 30. The front forwardly offset lower portion 31 having the top wall 32, as shown in Figure 2, the top wall 32 having a rearwardly extending portion 33 forming part of a finger-receiving recess 34 formed in. the upper left corner portion of the receptacle 12 for a purpose presently to be described.

enclosure in the lower portion of which the inclined Designated at 35 is a vertical plunger member which extends slidably through an aperture 36 in the top wall 32 located forwardly adjacent the recess 34. The lower portion of plunger 35 is formed with rack teeth 37 which meshingly engage corresponding. rack teeth 38 formed on the end of a lever 39 which is rigidly secured on a transversely extending pivot shaft 40 rotatably mounted in the lower portion of front wall 18, whereby the. lever 39 is disposed in the auxiliary housing, desig nated at 42, defined by the front wall member '31 and the top wall segment 32.

The pivot pin 40 is formed at its end with a diametral notch 43 in which is secured the inner end of a spiral spring 44, the outer end of said spiral spring extending through and being anchored by a ,transverse slot 45 formed in the top wall segment 32. Thus, the spiral spring 44 biases the lever 39 in a clockwise direction, as viewed in Figure 1, whereby the plunger 35 is biased upwardly. I

Designated at 46 is a vertical carriage. member or plate having the

vertical side edges

47, 47, the plate 46 being disposed forwardly of the restricted toothpick-dispensing passage 14 and being located adjacent and parallel to the lower edge 48 of the inclined receptacle bottom wall 13. The carriage plate 46 is formed with the respective side flanges 49 and 50, said side flanges being perpendicular to the main body of the plate and being arcuately concave at their edge portions, as shown at 51, whereby the top and bottom corners ofthe'flanges engage the inside surface of Wall 18 at limited areas, minimizing frictional resistance of the carriageplate 46 with respect to wall 18. The main body portion of the carriage plate 46 is of aheight such that the top edge thereof, shown at 53, is located immediately adjacent to the lower edge 48 of the inclined receptacle bottom wall 13 when the carriage plate 46 is in its lowermostposition, as shown in Figure 6, whereby the lowermost toothpick in the stack supported on the bottomwall 13 will rest. on the top edge 53 of the carriage plate46. As' shown in Figure.6, ,t he edge portion 53 of the carriage plate 46 is incline'djjsub stantially in the same direction as'the' receptacle bottom wall 13 and normally is substantially flush with the plane of the bottom surface of the inclined bottom 'wall 13 of the receptacle, to facilitate the reception of the lowermost toothpick on theedge 53.

Designated at 54 is a pusher member which 1s resiliently connected to the carriage plate 46 by a leaf spr ng 55, as shown in Figure 6,, the pusher member 54 being spaced above the top edge 53 by a distance approximately equal to the diameter of a toothpick.

The pusher member.54 is substantially rectangular in shape and is of substantial area. The leaf spring 55 is formed at its upper portion with .a rearwardly extending U-bend 56 which slidablyengages 'the'inside surface of the wall 18 and which is .cammingly-engageable with .a cam-like rib 57 formed on the intermediate portion of wall 18 and being .cooperable with the U-bend 56'to rotate the pusher member 54 in a clockwise direction, as viewed in Figure 6, responsive to the elevation of the carriage plate 46, whereby to push all except the lowermost toothpick of the plurality of toothpicks arranged so that their axes .are parallel to each other and transverse of the sloping bottom wall of the receptacle rearwardly and to be positioned substantially in vertical alignment with the carriage plate 46 as the carriage plate moves upwardly in a manner presently to be described.

The wall 18 is formed with a vertical slot 57 which slidably receives a vertical lug element 58 formed on the carriage member 46, said 'lug element 58 serving to guide the carriage member vertically and being formed with a shaft portion 59 which extends through a slot 60 formed in the end portion Of the lever 39. A retaining washer 61 is secured on the outer end of the shaft element 59, whereby the end portion of the lever 39 is slidably and rotatably connected to the carriage member 46, and whereby the carriage member .46 is elevated responsive to counterclockwise rotation of lever 39, as viewed in Fignrei A vertical guide :strip .64 is secured to the inside surface of the wall 18 adjacent the carriage flange 50, as shown in Figure 3., andadjacent to one side edge 65 of the generally rectangular notch formed in the forward margin of the inclined bottom wall .13, of which the forward edge portion 48, previously described, is a part. The flange 49 of the carriage member 46 is slidably disposed adjacent the .opposite side edge 66 of said rectangular notch, as is clearly shown in Figure 3. a

The recess 34 is defined by the laterally facing downwardly and inwardly inclined wall element -70 and the vertical forwardly facing wall element 71, as well as by the rearward extension .33 -.of top wall element 32. The wall-element 70 is arranged-transversely of the-carriage plate 46. Wall element 70 depends a substantial distance below the rearward extension 33 of the top wall member 32, as shown in Figure 7, whereby the bottom edge 72 of the wall member 70 is adapted to function as a stationary abutment against which one end por: tion of a toothpick engages while the intermediate portion of the toothpick is elevated by the top edge 53 of the carriage plate 46, .as will he presently described. As shown in Figure 7, the abutment edge 72 is located adjacent to but is spaced from one end margin of the bottom wall 13, namely, the margin which is secured to the wall 19. As shown ,in Figure 7, the bottom wall 13 has the downwardly and inwardly inclined end p01- tion 74 located below the abutment :edge 72, the portion 74 terminating in the side edge 66 of the :aforesaid rectangular notch formed in the forward marginal portion of said bottom wall 13. FIhe inclined portion 74 of the bottom wall provides adequate clearance to vallow the lower end portion of a toothpick .to be shifted toward a substantially vertical position responsive to the elevation of the carriage plate 46 while the .toothpick engages against the abutment edge 72 of wall 70. v v r The top wall portion 28 is formed with ;a tapered end portion 79 of the slot 75 located over the space 30, as shown in Figure 2, the slot extending from the side wall 20 for a substantial distance toward the side wall 19 and terminating adjacent the wall of recess 34. A horizontal leaf spring 76 is secured to the upper portion of the depending toothpick-restricting partition plate 16, said leaf spring 76 having the arcuately curved, hook-like end portion 79 extending across the end portion of the slot 75, as shown in Figure 1, and serving as a supporting retainer for holding a toothpick, shown at 80, in a vertical position after the toothpick has been forced past the arcuately curved hook portion of the leaf spring.

A cam lug 81 is secured to the partition wall 16 adjacent to but spaced from the side wall 20, the cam lug 81 having its forward surface inclined upwardly and forwardly toward the slot and cooperating with the upwardly and rearwardly inclined rear edge 82 of the guide strip 64 to guide a toothpick toward the slot 75 as the toothpick is being rotated from a horizontal to a vertical position 'by the elevation of the carriage plate 46 As shown in Figure 1, the slot 75 flares in width toward the wall 20, the widest portion of the slot 75 being located adjacent the wall 20, so as to provide ample clearance for the end of a toothpick to be elevated through the slot as the toothpick is rotated upwardly.

In using the device, a quantity of toothpicks are stacked on the inclined bottom wall 13 of the receptacle 12, the lowermost toothpick engaging on the top edge 53 of the carriage plate 46. To dispense a toothpick, the operator places his finger 0n the top end of the plunger 35 and pushes downwardly, the operators finger entering the space 34. The lever -39 is rotated counterclockwise, as viewed in Figure 5, causing the carriage plate 46 to be elevated. In the initial portion of execution of the upward movement of thecarriage plate or member 46, the U'bend 56 on the upper portion of leaf spring 55 camniingly engages the cam-like rib 57, causing the pusher member 54 to be shifted to the right, as viewed in Figure 6, pushing all of the toothpicks to the right, except the'lowermost toothpick, which is thus held between the carriage plate 46 and the side flanges 49 and 50 of the carriage plate 46, and then the pusher member 54 is moved away from the bottom wall 13 and out of vertical alignment with the carriage plate 46. The remaining portion of execution of the upward movement of the carriage plate or member 46 causes in turn the intermediate portion of the toothpick supported on the plate 46 to engage the wall member bottom edge 72 or abutment, the end of the toothpick below the bottom edge 72 to contact and ride along the inclined portion 74-of the bottom wall 13, and the intermediate portion of the toothpick to contactand ride about the hook-like spring 76 which bridges the slot 75 and be received in the inner end portion of the slot 75 and be heldin such slot portion by the hook-like end portion 79, resulting in thetilting of the toothpick from the horizontal position to the upright position in which the upper end portion .projects above the slot '75 and is held in this upright position until manually removed. The parts return to their normal positions when the plunger .35 is released, preparing the apparatus to dispense the next toothpick.
