C. BARBIERI EJECTOR MCHANISM FOR PAPER CUP DISPENSERS Filed July s. 1922 Yig- .v I i l Patented Sept. 4, 1923.
CESARE BARBIERI, 0F NEW YORK, N. Y.,
ASSIGNOR TO THE VORTEX MFG. CO., OF
CHICAGO, ILLINOIS, A CORPORATION 0F ILLINOIS.
EJ'ECTOR MECHANISIJI FOR PAPER-CUP DISPENSERS.
Application filed July 3, 1922. Serial No. 572,521.
that the following is a. full, clear, and exact description of the lsanie, reference being` had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.
rlhis invention relates to containers of the sort that are intended to hold fiat sector-shaped drinking cups of paper or other material which are folded into a flat shape for storage in the container and expanded into cup shape for drinking.
It is an object of this invention to provide a container of the sort described with an ejector mechanism which shall remove one cup at a time from the container.
It is a further object of this invention to provide an ejector mechanism that can be operated by one hand ofthe operator with the hand in position to receive the ejected It is a furthe-r object of this invention to provide means for retaining theother cups in position so thatV only one cup will be ejected.
It is a further object of this invention to provide a device of the class described which can be madeof stamped; sheet `metal without the necessity of any expensive operations in the manufacture thereof.
Other and further important objects of this invention will be apparent from the disclosures in the drawings and specification..
The invention (in a preferred form) is illustrated inthe drawings and, hereinafter more fully described.
On the drawings: j Figure 1 is a side elevation of the device. Figure 2 is a front elevation.
Figure Sis a detailed section showing av portion of the ejector. j
Figure 4 is a section on the line @1f-4 of Figure 2.
Figure 5 is a section upon the line 5-5 of Figure 1.
As shown on the drawings: i
The container has a main body of approximately columnar form with a crosssection corresponding' to the shape of the folded cup.` The` container therefore has a curved side 10 and twowide converging faces 11 connected at their nearer edges by a narrownat face 12. Each of the 4faces 11 is provided with a window 13 in which is secured a transparent material 14 such as A glass, mica, celluloid or any similar sub` stance. The sheet 'of transparent substance is retained in place by clips 15 or in any other desired lway. The container is supe, j ported by means of a bracket (not shown) secured to the curved surface 10 in any desired manner.
The lower edges of the faces 11 are provided with short inturned flanges 16 shown.
in dotted lines in Figure 5, atk their rear ends, that is the ends nearest the curved surface 10. The other ends of the lower turned ianges 17 also illustrated in dotted lines in Figure 5. Near the latter ends of the lower part of the faces 11 are pro-vided ytongues 18 projecting forwardly from the outer surface of the container. |The forwardy ends vof these tongues are `turned downwardas shown at 19 in Figure 1 tor afford a stop as will be 'explained below.
Secured to the narrow face 12 at any desired height above the bottom is the fiat end 2O of a leaf spring 21. This end is secured by soldering, riveting' or in any other desired manner. The lower end of the spring 21 projects forward from the lower end of the face 12 an abundant distance to provide for the motion between the;
`the stops 19 fixes the forward position of the spring. The enlarged `portion of the horizontal part of the vspring is provided with'a recess 24 ofa shape to fit the small ends of the folded cups. The flaring sides of this recess meet the edges of the enlargement 23 in points 25. Secured to the under side of the horizontal part 22 is a tongue 26 which is fastened to the horizontal part by riveting, soldering, or in any other desired manner` l"he rear wall l() of the container does not extend all the way down to the level of the flanges 1G, but terminates above that level by a distance equal to the thickness of one cup as shown at 27 in Figure 4. Projecting guide pieces 28 are provided at the rear ends of the lower margins of the faces ll. Preferably these pieces are made by cutting away and bending into this position por tions of the round surface 10. r)The cut away places are shown at 29. The guides 28 project parallel to one another and parallel to the direction of motion of the horizontal parts 22 of the spring 2l. lf he lower edges of the guides 2S are in the same plane as the lower surfaces of the flanges 16. rllhey project downward therefore further than the lower edge of the curved face l0.
ln the operation of the device`r the container is filled with a pile of flat folded cups. These cups when folded are shaped like the sector of a circle except that instead of a point they have short edges or small ends where the points have been folded against the bodies of their cups. The small ends of the cups contact withk the inner surface of the face l2. The radial edges of the cup contact with the inner surfaces of the faces 1l and the curved edges. of the cup contact with the inner surface of the facer l0. The lowermost cup rests upon `the flanges 16 and 17. After the cups are placed in. the container, if desired the upper end `of the container may be covered with any suitable closure (not illustrated).
llhen it is desired to remove a cup from the container, the operator thrusts 'his hand beneath the container letting the end of the palm nearest the wrist vcontact with the lower part of the spring 2l. This pushes the spring 2l backward toward the curved vface l0. The limit of this motion is reached when the spring 2'1 contacts with the face l2. rillhe rearmost position of the horizontal part 22 of the spring is illustrated in dotted lines in Figure 5, f3 being the rearmost position of the shoulders 23, 2r" the corresponding position of the points 25, and 2G the corresponding position of the tongue 26.
, i-ls the part 22 moves toward the dotted line position, the recess contacts vwith and guides the movement of the small end of the cup. The corners of the cup at the two ends of. the curved edge thereof Contact with the guide pieces 2S. T cupl therefore is guided at all four corners while being moved by the inward motionof the parts 22. During the first part of this motion, the anges 17 and 1G support the cup.
After the cup has moved rearwardly far enough to escape these flanges, it is supported only by the tongue 26 and the operators hand. The cup therefore drops naturally into the operators hand. The operator continues to nieve his hand toward the rear, lowering it slightly to escape the front lower-edge ofthe container and the spring 2l. This movement leaves the cup wholly free from the container and resting in the operators hand. lWhen the hand is withdrawn from the spring 2l, either by being moved downward far enough to escape it or by being again drawn forward, the spring returns by its resiliency to its normal position. Meanwhile,the remainder of the cups descends by gravity and rests upon the flanges 17 and 16. They are thus in position for the removal of the ne-Xt cup when the operator again moves the spring backward.
I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and l therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
