MIXING DISPENSER Filed Aug. 16, 1954 mam United States atent MIXING DISPENSER Arthur H. Ackerman, Jr., Jackson, Mich. Application August 16, 1954, Serial No. 450,160
4 Claims. (Cl. 222-48) The present invention relates generally to dispensers and, more particularly, to an improved dispenser capable of mixing and dispensing a predetermined quantity or" substances, such as dental alloys, mercury, and the like, for use in dental work, and for other purposes.
An important object of the invention is to provide a mixing and metering device including the provision of a hopper having a plurality of storage chambers therein, with each of said chambers having an opening at the top thereof for loading, and a. discharge port at the bottom for unloading. The walls of the storage chambers taper downwardly and inwardly to form a substantially square discharge port. A. cylindrical discharge valve is herb zontally rotatably disposed below the discharge port and is operative to receive a metered quantity of substance from each of the storage chambers and deposit it in a discharge funnel or chute. The cylindrical discharge valve is hollow at each end and is provided with a graduated cylinder adjustably mounted in each of said hollow ends whereby, the quantity of substance withdrawn from each chamber may be varied as desired.
Another object of the present invention is to provide a dispenser especially adapted for dental use which has a measuring valve of a variable capacity so thatit will, for each operation, measure any desired quantity of substances, as for example, an alloy and mercury, and mix the substances for ready use thereof.
Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawing, in which:
Figure 1 is a perspective view of a dispenser made in accordance with the principles of the invention;
Figure 2 is a vertical cross-sectional view of the dis" penser illustrated in Figure 1, showing the discharge valve partly in section; and
Figure 3 is a vertical cross-sectional view of the structure illustrated in Figure 2, taken along the line 3--3 thereof.
Referring now to the drawing and, particularly, to Figures 1 and 2, the reference numeral ll) designates the hopper of a dispenser made in accordance with the principles of the present invention. The outer shape of the hopper is shown as being substantially square in cross-section but, it will be understood that any other suitable shape could be used for the hopper, as for example, it could be circular in cross-section.
As is best seen in Figure 2, the hopper It) is provided with a pair of spaced storage chambers 12 and M which are open at the top and bottom ends thereof. The walls of the storage chamber 12 and 14 taper downwardly and inwardly to form a substantially square discharge port. The hopper 10 is provided with a chamber to which is disposed so as to divide the hopper in two portions and to provide a working space for another part of the dispenser as described hereinafter.
The open top end of the hopper it is provided with a cover 18 having a downwardly extending portion 2@ adapted to be seated snugly within the upper end of the hopper. The cover 18 may be provided with a suitable handle portion as designated by the numeral 22.
A transverse bore 2 is provided in the lower end of the hopper lit. The transverse bore 2 carries therein a pair of spaced sleeve bearings 26 the outer ends thereof being desi, ted by the number 28. The sleeve bearings 12s? hi an inner end 27 connected to the outer part thereof by means of a pair of spaced longitudinal members 29 so as to form an upper opening 3t) and a lower opening 31 communicating with the storage chamhers and to a discharge funnel, respectively.
A discharge valve 32 is rotatably mounted in the sleeve bearings and is provided with a solid center portion and hollow end portions. As is best seen in Figures 2 and 3, the hollow endportions are provided with an upwardly facing opening 34 which is disposed below the discharge opening of one of the storage chambers 12 and is in communication therewith. When the discharge valve 32 is rotated clockwise, as shown by the arrow 33, the lower side will be pivoted upwardly and the opening 34 will face downwardly so as to discharge any substance it has therein which it received from the chamber 1.21. The openings may be provided with vertical edges as 36 to permit easier emptying thereof.
The capacity of the hollow end portions, of the discharge valve may be adjusted and varied as desired by means or the graduated cylinders id and 42 which may be calibrated as desired. The graduated cylinders as and 4?. may be slidably or threadably mounted in the hollow end portions as desired. it will be understood however, that the cylinder 42, for the mercury storage gcharnber, assuming that is the substance therein, must be fitted in the discharge valve within close limits of tolerance, so as to prevent any leakage of the mercury.
A handle is fixedly secured to the center portion of the discharge valve 32 as designated by the numeral 46. The handle is biased upwardly to a non-operative position by means of a spring 43, the lower end of which is secured to the handle as at 5th and the upper end being fixed within the chamber 16 as at 52 on a cross member As is best seen in Figure 1, the handle 44 extends forwardly from the chamber 16 and through a slot 56 in the side of the hopper 16.
As is best seen in Figure 2, a funnel or discharge chute 55b is provided on the lower end of the hopper and suitably secured thereto. The tunnel S8 is arranged to receive the discharged substances from the discharge valve and permit them to be mixed in the funnel interior till and then to be discharged to a suitable receiving container through the spout 62.
in operation, the chambers 12 and. 14 would have therein substances which it is desired to mix in certain proportions, as for example, an alloy and mercury. The desired proportions would first be carefully set by adjusting the graduated cylinders dtl and d2 accordingly. This action permits the hollow end portions to be filled by gravity with their respective substances and to the desired amounts. A suitable container is then put under the spout s2 and the handle M is depressed downwardly, thereby turning the discharge valve 32 in a clockwise direction as shown by the arrow 38 in Figure 3. The substance in each of the hollow valve end portions will be discharged into the funnel interior (it) and the handle is then released and it will be returned to the upper inoperative position by the spring 43.
While it will be apparent that the prererred embodiment of the invention herein disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claims. Also, it is to 6 be understood that the phraseology and terminology employed herein is for the purpose of description and not limitation.
