An object of this invention is to provide a dispensing device which 'is adapted "to cooperate with the containers of the material to be dispensed so as to open the containers automatically when such containers are to be emptied into the dispensing device.
A further object of this invention, is to provide a dispensing device which is adapted to hold the container for the materials to be dispensed in such a position that such container will act as a reservoir for the material.
Other objects will appear during the course of the following description.
In a preferred form of the dispensing device, an upper chamber is provided which is adapted to hold the container. This chamber is preferably designed to hold the-container in upright position in which position the material therein will readilyflow into the dispensin chamber of the device. The dispensing c amber of the device is positioned below the chamber adapted to hold the container and is preferably of decreasin diameter downward. It may take the orm of either a downwardly pointing truncated cone or pyramid. Attached to the wall of one of the chambers is a projection. or finger which is adapted to open the bottom or top of the container when it is positioned in the upper chamber of the dispensing device. This finger is ordinarily adapted to cooperate witha scored or weakened portion in the botto or top of the container which is usual y of paper. The projection or finger is of such construction that it will make a sufiiciently' large opening in the container to permit the necessary amount of material.
to flow out into the dispensing-chamber'of the device. Positioned below the dispensing chamber is a manually operated device which is adapted to remove a small portion of the material in the dispensing chamberand then conduct it to a discharge spout where it may be utilized.
' of the container,
1928. Serial No. 296,387.
The drawing shows one embodiment of the invention to which the invention is by no means restricted.
Figure 1 represents a vertical sectional view of one form of the dispensing device; Figures-2, 3 and 4 represent longitudinal sectional views upon the lines 2-2, 3-3 and 4-4 of Figure 1; and Figures 5 and 6 represent vertical sectional views of a form of the dispensing device with a modified manually operated device.
In' Figure 1 the dispensing device is shown with a downwardly pointed truncated py-, ramidal chamber 10 which is rectangular in horizontal cross section. dispensing chamber. The chamber is provided on its longest sides with downwardly and inwardly sloping walls 13 and on. its shorter sides with downwardly and inwardly sloping walls 14:. Connected with the top and the widest portion of the dispensing chamber 10 is a rectangular prismatic chamber 15 provided with verticalwalls. This chamber is adapted to hold in upright posi tion' a prismatic container of substantially rectangular horizontal cross-section. Projecting from the outside walls of this container holder chamber are the ears ll which are provided with openings 12 by means of which the dispensing device may be attached toa suitable wall or other means of support. Attached to the back wall 13 of the dis pensing chamber is the projection or upward- 1y extending finger 18 which extends up into the container-holding chamber. 18 is adapted to penetrate the-bottom or top placed in the container-holding compartmen't, either by tearing the same or by co-" operating with a scored portion therein. In the embodiment. shown the projection or finger 18 preferably cooperates with a scored portion in the'top or bottom of the container. It will be noted that the finger 18 is long and narrow and is of decreasing dimension upwardly. Due to its sha e and position, it is adapted to assistthesi e walls of the holding portion and the stops inliolding the material container in position and preventing its This chamber is the The finger according to which side is:
as that of a hexagon, square, circle, ellipse,
etc. depending upon the type of container which it is desired to position in the chamber 15.
In the embodiment of the invention shown in Figures 1,2, 3, and 4, the bottom ofthe dispensing chamber 10 is providedwlth two openings 17 which are separated by the upwardly projecting ridge 16 which is adapted to direct the flow of the downwardly flowing material toward either one of the openings 17 The exit faces of these openings 17 are flattened so that the upper surface of the contact strip 31 of the manually operated dispensingelement may cooperate therewith. The manually operated dispensing element is provided with a central portion 32.
Through the upper portion 31 and central portion 32 penetrate the conduits or openngs 33. These openings 33 are adapted to cooperate with the openings 17 but are positioned a much shorter distance apart. The openings 33 are separated by about half the distance as are the openings 17. The bottom of the lower portion 32 of the manually operated dispensing element is also flat so that it will cooperate with the upper flattened surface or piece 35 of the spout member. This spout member is provided with a central opening 45 which extends through the contact piece 35 and which communicates with the spout 48 from which-the dispensed material may be collected for utilization.
The reci rocating dispensing element is provided with a radial arm 38 (see Figure 3) which is attached to a cylindrical piece. 37.
The piece 37 is held between the lateral stops 39 and the rear piece 40. These two pieces 39 and 40 are provided with areuate surfaces 41 and 42 which are adapted to contact with pivot .element 37 of the reciprocating dispensin device. The radial arm 38 is stoppe in its reciprocating motion by the surfaces 43 of the lateral pieces 39. To the rear of the spout element 45 is attached the frame element 46 (see Figure 4) towhich are attached the lateral pieces 39 and the rear piece 40. The dispensing element may reciprocated by the handle 47.
.- It is apparent that when one of the openings 33 is below one of the-openings 17, the
other opening 33 is above the opening 45 and is discharging its contents. These openings 33 are made of suflicient size to contain the desired amount of flow'able material which is to be dispensed intermittently. As the handle 47 is moved back and forth reciprocating the dispensing device, the pockets 33 will alternately be below.an opening 17 and above an opening 45, at the end of each stroke.
The stops 43are so placed and thedistance' between the buckets 33 is so proportioned that when one pocket 33. is under the opening 17 the other pocket 33will be above the opening ment in this embodiment of the invention is circular and is provided in its central portion with two opposite pockets 62. These pockets 62 are adapted to cooperate with the opening 59 and with the open spout alternately. When one pocket 62 is filled or being filled from the opening 59, the other is empty or emptying into the spout 70. The dispensing device is attached to a central shaft 63 which isprovided with handle 64. The handle 64 is provided with a sleeve'65 which is attached to the shaft 63 and which is also provided with two radially opposite notches 66. The ball 67 is forced into these notches at each half turn of the handle 64 by means of the spring 68. This affords a means of causing the dispensing device to operate intermittently upon manual operation. The shaft 63 is attached to the rotatable pocket-containing member 61- by the set screw 69.
In the embodiments of the inventionpockets 33 isplaced below an opening 17 1n the embodiment shown in Figures 1 to 4 or when one of the pockets 62 is placed beneath the opening 59 in the embodiment shown in Figures 5 and 6, such bucket will be filled with the material contained in the dispensing chamber 10. Then the manual- 1 operated element may be moved so that t e pocket 33 or 62, now filled with the material to be dis ensed, will be moved over to a position w ere it will empty into the discharge spouts 48 or 70 and allow the material tofall out of the pocket into the band or into another container positioned below such spout. When this is done, the other pocket 33 or 62 is moved into position below the other opening 17, in Figures 1 to 4,
or below the same opening 59 in Figures 5 and 6 permitting a flow of the material in the dispensing chamber 10 into such pocket. The first pocket after it has emptied may be moved back to the opening 59 to be refilled while the second pocket 33 which was being filled while the first pocket was being emptiedis now moved to a position where it will discharge its contents into the discharge spout 48 or 70. i
If a square container is to be used instead of a rectangular one, then chamber 15 will be made square in horizontal cross-section. If the container is circular or elliptical in cross-section, the chamber 15 may be con: structed. so as to be of similar shape in horizontal cross-section. The device of the present invention is adapted to dispense material such as soap flakes or powder, salt, sugar, chemicals, etc. It is especially valuable in connection with the dispensing of a powder -or flakey material in which there is a strong tendency toward waste. The dispenser is preferably used in connection with a vertlcal paper container, one end of which has a weakened or scored portion which will be broken by the inwardly projecting finger 18 when the container is placed in the top of the dispenser.
