CUP-DISPESING APPARATUS.

Original application led VJuly 23, 1919, Serial No. 312,806. Divided and this application led February 20, 1022. Serial No. 531,797.

This invention relates to an improvement in cup dispensing apparatus and more particularly -for dispensing nested paper cups.

A large portion of the paper cups used to-day at soda fountains, or which are disused in railroad cars, stations, or at drinklng fountains, are of conical form, and are provided with an annular flange at their larger end or the top thereof. These cups are usually nested in a container or dispensing device, and are removed one by one as they are tobe used. 4As the taper of these cups is usually of a very slight angle, the cup to be removed frequently sticks to the next cup to s uch an extent that the delivery mechanism Will frequently miss delivering a cu when it is actuated` T e object of my invention is to provide dis ensing mechamsm which is so arranged and] actuated as to insure the delivery of a so long as there is a supply of cups in the container.

I accomplish this object by providinrr a `plurality of holders and ejectors, prelerably three, which are arranged to 'engage the flange of the second cup to restrain said cu against movementLand to simultaneous y en at a plurality of oints, the flange o the cup to be ejected), and move the cup parallel to the axis of the cups to prevent jamming or locking of the first cup within the second cup! A Another object of my invention is to provide devices vof this character which will `engage the anges of the'cu s at ints close to the junction of the bodp an ange of the cup, as well as device w lch will enga a large area of the ilange, to distribute tg ressure exerted thereon over a relatively arge surface.

he' precise nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, 1t being premised, however, that changes may be ma e in the details of construction wxthout departing from the spirit and scope of my invention as deined in the ap ended claims.

igure 1 is a plan view of one form of cup olding and delivery mechanism, built in accordance with my invention.

Figure 2 is a sectional view on the line 2 2, of Fig. 1.

Figure 3 is a similar view on the line 3-3 of Fig. 1.

Figure 4 is a detail bottom view of one pair of the cup holding fingers and their carrying slides.

Flgs. 5, 6 and 7, perspective views showing respectively the upper and lower lingers, the ejectors, and their actuating devices, in their several positions.

In these drawin the reference character 36 designates a cy indrical container which is partially cut away to permit the insertion of a stack of nested paper cups 37. The container 36 is supported within an annular flange 38 on a base member 39, which may be supported in any desired manner within a sulta le case or cabinet.

The nested cups are sulported in an upright position by means o suitable fingers, w ich are in engagement with either the annular flange 40 on the lower cup or a similar -flange on the next to the lowest cu when the lowest cup is being ejected. glidably mounted for radial movement in guides formed in the base plate 39 and angle plates 42 secured thereto, are lower and upper cup su porting fingers 41 and 45 respectively,- an which are moved to t eir retracted positions by respectively.

44and48arecam inanannular seat in the base plate 39, and lare each rovided with three recesses and three 'gh points, for actuating the three fingers 41 and 45 of the two sets through the medium of r'ollers 41, 45, on said lingers, and are retained in engagement with the cams by means of the springs 43 and 47. The rollers 41 are shown in igs. 2 and 3, the rollers 45l being shown in full lines in Figs. 2 and 4 and in dotted lines in Fi 1.

49v are ejector levels t ere being one mounted on each of the lower rs 41 on a in 50, and are arranged to e moved ra ially with said lingers. Each ejector lever is provided with an extension 51, havin projections between which is mounted a ro er 52. 53 are cams on the cam r' which are arranged to pass under ro ers 52 when the cam rings are rotated as hereinafter described, to rock the ejectors 49 and eject the lowermost cup 37.

The cam rings 44 and 48 are secured to each other by means of screws 65, and 61 is an operating handle secured to the top cam ring 4S and is normally held against a stop plate 63, by springs 54. These springs the springs43 and 47,`

54 are connected to pins on the upper cam ring 48 and pins on the base 39. 4 Pivoted to the base 39 is a locking lever 55 which is normally held in the position shown in Figure 1 by a spring 57, so that the end thereof is within a low point in the cam ring 44 and prevents shoulder 66 passing beyond the lever 55, unless the lever is first withdrawn, as hereinafter described.

56 is a cam face on the lever 55, in line with the ed of coin 58 when inserted in a slot in the and. lever 61.

Connected at one end to the base 39, is a plate 59 having ratchet teeth 6() at the other end'thereof, and which plate extends along the line of movement of the coin in the slot in the hand lever 61, for supporting the coin 58, throu h the major portion of the movement of t e coin.

67 is a coin chute extending from the annular flange 38 to the wall of the 'casing and is arranged to deliver the inserted coin to the slot in the hand lever 61.

The arts are normally in the position shown in the drawi and in which the fingers 45 and their ejecting levers are retracted to' oints beyond the flanges 40 of the cups 3 and the rest of cups is supported by the fingers 41 which are advanced under the flan e 40 of the lowermost cup.

When it is esired to eject a cup, a coin is inserted in the chute 67, which will pass into the slot in the hand lever 61, as shown in Figs. 1, 2 and 3.

The hand lever 61 is now moved clockwise and during its first movement the coin will ride along the cam face 56 on locking lever 55 and move the lockiii lever out of the line of movement of shou der 66 before said shoulder reaches the end of the lookin lever, so that the cam rings can be actuated a sufficient distance to e'ect a cup. In this clockwise movement of t e cam rings 44 and 48, the high points on the cam ring 48 will first engage the rollers 45 on fingers 45, and advance said fingers together with ejecting levers 49 between the flanges 40 of the lowermost cu 37 and the next cup. In the further rotation of the cam rings, the low points of cam ring 44 will be moved opposite the rollers 41* on fingers 41 and permit said fingers to be withdrawn from under the flange on the lowermost cup by the springs 43. The cams 53 in the further movement of the cam rings 44 and 48 will pass under rollers 52, rock said levers and as the inner ends thereof are between the flanges 40 of the two lowerrnost cups, the lowcrinost cup will be ejected by said levers while the second cup, together with the reniainder of the cups, will be supported by the fingers 45. The hand lever 61 is now released and as the coin has been moved beyond the free end of plate 59, it will drop through the slot in the hand lever and permit the spring 57 to move the locking lever 55 into locking position and the cam rings will be returned to the positions shown in the drawings, by springs 54.

If it is desired to provide ejecting mechanism without the use of a coin, it is on] necessary to omit lever 55, and in whic case the mechanism can readily be actuated to eject cups one by one.

The advantages of my invention result from the provision of cup dispensing mechanisin having a pluralit of ejectors which are arran ed to move in planes substantially para lel to the axis of the cup to be ejected, so as to move the cup in a direct line. I

Another advantage results from the provision of radially movable cup holding fingers carrying cup ejectors which are so ar-4 ranged that the fingers are first moved into position to hold the second cup while the ejectors engage the first cup to stri it from the second cup. This provision o radially movable fingers also permits the provision of fingers and ejectors having broad bearing surfaces, as well as permitting the en- Uagement of the cup flanges at or near their junctions to the cu bo ies. The expression radially mova le fingers means that said fingers are movable toward and from the common axis of the supporting frame, cup-container, and cups.
