B eTIm ts 'MQ t ANA DISPENSING Application filed May 7,

This invention relates to a 'dispensiirg machine, and? has for an ob ect the p govislon or a simple and efficient improvement onthe dispensing machine shown in. my Patent rial from the'hopper tothedelivery device isprevented until predetermined periods in the operation of the device. A still further object concernsfthe provision of means whereby the operating-parts are simplified in their construction so that the cost of manufacture is considerably re duced. Another object concerns the prov s onot means whereby the delivery of ran article to the position of'd'elivery is rendered more certa'i'm, so that, anarticle .is dellvered every time the device is operated I The invention is illustrated the drawings; ofwhiclr- V v Figure 1 is a side elevat on of the device; .Fig. 2 is a horizontal section taken on the line ofFig. 1;

pivoted member which, at its rear end with-i in the casing 01 the dispensingwdevice, is formed as a material receiving trough or reservoir divided into compartments, one compartment adapted to receive material from a material hopper and the other compar-tment adapted "to contain material, and from which'l'atter compartment-':the material is delivered to a delivery positionrso that it can be transferred-by the movementof the pivoted member to a chute, forming-part of said member; down which: chute ittravels to a posit-ion where it can be gras ed by the person. operating "the device; En further particulars the improvement relates to a sim-J plilled tormofi operating device which can bernademuch more economically and; preferably, of a minimum number of parts,'so that emnomy "of manufacture is insured and the complexity of-the device" is reduced. 7 In the operationot the member a"consilent-barrier'is 'dispose'd between a main 7 hopper a-nd the'material'trough, so thatn'o material can get out-of thehopperinto the casing-of the device and can only'get into the troughformedbmthe pivoted inemher when such member is in a predetermined position, This ;-s tru"ctural idea g imthe purpose of positively 'oontrollihgithefdelivery of articles to be dispensed firom "the hopper to the trough an'dfto regulate "the periods duringwhich such delivery-" takes place.

The device further oonte'mplatesf the operation of the pi-lvotejd member merely by? the seizure 'Offth article exhibited in the hand of the'o erator andin a natural manner withdrawing-f it ffrom 'the device. During this withdrawal the pivoted member" moved in' such-a manner thata newfarticlfe ismove'd' to"the delivery-position andmore material is fedto the trough or reservoir. Upon the release of the pivoted-(member from the hand of the OP eIdtQlf gravity re- I stores; the 'member-Jto; normal j-position, and

inrestqring it to nor-malflposition a new arti} ole slides, dowrf the'chute and: the-reservoir or trough cut o'fiiiromg t ljie main hopper I to stop any further-transmission of) material "from hopper'tothe trough.

Asshown in the'draw-i'ngs', which illustrate the preferred formiof 'the invention, I provide "casing l in" which plates '2] and are cl'isposedaiihese platesiflfor'fning a hopper to. receive am es suchasf toothpiblss -ili ner ends. This space forms an opening through which material would ordinarily pass from the hopper.

Adjacent this Open space or discharge opening of the hopper I disposea pivoted delivery member, preferably pivoted. in the casing as at on suitablepins. This delivery member is formed, preferably, of sheet material, and at its rear end is provided with a trough 6. This trough 6 is formed by bending the material of the deliverymember to form a rear wall 7 and a front wall 8. This trough 6 is divided into twocompartments by the dependence into the trough of an intermediate middle wall 9-formed ofsheet material. The upper edge of the rear wall T is disposed at a, certain level above the bottom of the trough 6, and the upper edge 10 of the intermediate wall 9 is disposed at a much higher level than the upper edge of the Wall 7. The lower edge. 11 of the intermediatewall9 is disposed a slight distance from the bottom of the trough 6 and this space forms a communicating passage between the two compartments. of the trough. The rear compartment in the trough acts as a reservoir for articles such as toothpicks. The front compartment acts as a similar reservoir and opens into a forward portion of the delivery member. This forward portion is in the form of spaced plates 12 and 13 having side plates lt-and 15 to form an enclosed chute down which the toothpicksmay-travel in a manner similar to that referred to in the above-mentioned patent.

. The wall 9 is supported in position by a curved plate 16, preferably integrally con nected tothe pivoted member. v V The walls 7 and 9 are preferably curved,

their center of curvature being the pivoted axisof the operatingmember- The wall 7 is provided on its rear surface with ribs such as 17 which runin slots such as 18 formed on the plate2 to prevent the lateral movement of the wall.. It will be noticed that the plate 3 is curved in the same manner *as the wall 9 and in the movement of the delivery member these walls lie adjacent each other. V v

Assumingthat a toothpick hastraveled down the chute and is resting on vertical plates 19 and 20, by. gripping the toothpick and pulling it forwardly the pivoted memher .will be .moved upwardly to the i fullline position shown in Fig. 5. This will.

lower the rear wall 7 of the trough until its upper edge is flush with the surface ofthe plate 2 whereupon toothpicks will drop into the rear compartment. At the same time, however, it is noticed that the intermediate wall .9 is acting as a barrier to closeoff the hopper from the other part of the casing.

Release of the pivoted member after the toothpick has been withdrawn therefrom. causes gravity to return the pivoted member that in the position shown in Fig. 5 a toothpick is supported in the manner previously described in my above-mentioned patent, in

notches in a pair of plates such as 23 and 24., and that upon the resumption of the normal position of the pivoted member this toothpick will be delivered into the position shown in Fig.6 so thatit canmove down the chute to rest on the plates 19 and 20.

It will also be noted that I have provided a stop post 25 which contacts with the under surface of the'trough 6, as shown in Fig. 5, when the trough has reached its ultimate position shown therein.

. In the operation of the device, when the pivoted member is moved to the position shown in Fig. 5 toothpicks will fall into the rear compartment of the trough, and as the pivoted member drops back to normal position these toothpicks will pass through the front compartment. As this normal position is being assumed, a toothpick will be transferred to the chute and pass down the chute. again from the normal position to the position shown in Fig. 5, a new toothpick is left supported in the notches on the plates 23 and 24: to be subsequently delivered to the chute. Calling the position shown in Fig.

4 the normal position, and the one shown in a Fig. 5 the abnormal position, it will be seen that in the abnormal position delivery of toothpicks to the hopper is efiected, and in the normal position delivery of a toothpick to the chute is effected. Itwill be Observed. that'at all times, however,,the hopper can only be put into communication with the trough. and with it only in the abnormal position of the pivoted member. Y

When the device is operated The simplicity of the construction ofthe pivoted member enables it tojact efficiently at all times, tobe very little likely to get.

out of order, and to be a construction which can be economically manufactured. It-will .be observed that. by supporting the barrier plate 9 from the curved plate 16 this curved plate16 acts as a sort of cover for the front compartment of the-trough. and results in a closed passageway leading from said fron compartment to the chute. V I
