MEASURING AND DISPENSING MACHINE.

Specification of Letters Patent.

Patented Jan. 21, 1919.

Application filed July 13, 1917. Serial No. 180,282.

To all whom it may concern:

' Be it known that I, MORTON G. BUNNELL, a citizen of the United States of America, and resident of Decatur, Macon county, 'Illinois, have invented a certain new and useful Improvement in Measuring and Dispensing Machines, of which the following is a specification.

This invention relates to measuring and dispensing machines of that kind in which means are provided for feeding the contents of an inverted bottle or other container downward therefrom in measured quantities.

It will be seen that this is an improvement over the construction shown and described in application Serial No. 157,330, filed March 26, 1917, in which the invention is claimed broadly.

The objects of these improvements are, to provide means whereby the feed device may be attached to the bottle, or removed therefrom, while the bottle is right-side-up, and whereby the feed device is readily removable from the machine for that purpose; to provide means to scrape the interior of the bottle, thereby to loosen the contents thereof; to provide a valve which will automatically open and close the opening in the bottom of the feed device; to provide the feed device with blades which are tapered downward in cross-section, so that the spaces between the blades are larger at the bottom than at the top, and whereby the feed device will not become clogged; to provide a feed device in which the blades are beveled at the ends thereof, with the bevel of each blade on the rear side thereof, so that the materials will be less liable to accumulate within and to interfere with the proper operation of the feed device; to provide a base having a recess in I which a cup may be placed to receive the materials from the feed device; and to provide certain details of construction tending to increase the general efficiency and desirability of a measuring and dispensing machine of this particular character.

To the foregoing and other useful ends, this invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings Figure 1 is a side elevation of a measuring and dispensing machine embodying the principles of this invention.

Fig. 2 is an enlarged vertical section of said machine, on line 22 in Fig. 1, with a which the said legs section on line 44 in Fig. 2, and with the feed plate omitted to show the feed wheel below.

Flg. 5 is a perspective, partly in section, of a portion of the feed device.

F 1g. 6 1s a perspective of a handle and valve whlch are mounted'on the bottom of the feed device.

As thus illustrated, the invention comprises a ring or member A of annular form, mounted on legs a, which latter are supported upon a base B, so that the member A is supported in suitably elevated position. Said member A has an outer flange 1 to are secured by bolts or screws 2, and has an inner flange 3 which forms a shoulder. The feed device comprises a hollow member 0 provided'with a shoulder (2 to rest upon the flange 3, and formed with an upper screw-threaded portion at to receive the screw-threaded neckportion 5 of the bottle D, which latter may be of any suitable form or character. Said member Chas a bottom 6 provided with a feed opening 7, and contains a rotary feedwheel E provided with blades c, said feedwhoel being mounted on a vertical shaft 8 which is mounted to rotate in the bottom of the member C, in any suitable manner, whereby the blades scrape the bottom 6 and also the cylindric sides 9 of said hollow member. The blades 1: preferably taper downward in cross-section, so thinthe spaces between the blades are larger at the bottom than at. the top thereof, thereby to prevent the materials from clogging in the feed device. Also, the outer ends of Said blades have beveled edges 10. the bevel of each blade being at the rear side thereof, whereby the blades scrape the cylindric inner surface of the member C, and so that the materials will not be compressed by the ends of the blades against the said cylindric inner surface of the chamber in which the feed-wheel rotates. The upper portion of the shaft 8 is provided with transverse rods or

wires

11 and 12 which serve as agitators to stir the materials in the neck of the bottle, thereby to facilitate the feeding of the materials feed into the Also, with a view to preventing the materials from brldging in the bottle,'and from failing to feed downward, athin flexible sheet-metal scraper F is secured to the upper end of the shaft 8, and is disposed in position to scrape the inner surface of the bottle at the sides thereof, thereby to insure properfeeding of the materials from the bottle through the operation of the feed device. The shaft 8 is rotated by a ratchet-wheel 13 secured to the lower end of the shaft and a dog or pawl 14 pivoted on the handle 15, which latter is suitably mounted to fulcrum on said shaft. A detent 16 is pivoted on the bottom of the member C, to engage said ratchet-wheel, and

' suitable sprlngs are provided to control said detent and also the dog or pawl 14, whereby the vibration of the handle operates the ratchet in a manner that will be readily understood. Stops17 and 18 on the bottom of the member C limit the swinging movement or vibration of the handle 15, so that for each vibration of the handle the 'ratchetisadvanced one notch, and the feed-wheel E is turned one space forward. The plate 19 covers one-half of the feed-wheel, directly above the opening 7 whereby a widefeed opening is formed by this plate, so that the wheel and'arethen ,carried around and dis* charged through the opening 7 ,when the handle 15 is swung over to a position to engage the stop 17,-it being understood that this carries the valve 20 out from under the opening 7 to permit the materials to dischargefrom the feed device. This valve 20- is preferably rigid with the handle 15, and with the arrangement shown the valve and the handle are disposed at opposite sides of the ratchet, so that when the handle is swung toward the stop 17 the valve 20 is swung toward the detent 16, thereby to open the bottom of the feed device and operate the feed-wheel by one and the same manual operation of the handle.

The machine can be used for any suitable or desired pur ose. For example, it can be used for dispensing malted milk, at soda fountains, or for any similar purpose. Malted milk and other similar materials are often packed 0r tamped into the bottles, but

with the provision of the scraper F this will not interfere with the proper discharge of the contents of the bottle; Whenthe handle is against the stop 18, beingyieldingly held in this position byspring means, the valve "20 is closed, and moistureis prevented from entering the feed .device at the bottom thereof. The threaded portion 4 is preferably provided externally with a pin 21 to engage the notch 22 in the upper edge of the member A, thereby to prevent rotation of the member in the member A when the feed pockets of the feeddevice is operated. To attach the feed device to a bottle, all that is necessary is to remove the usual screw-threaded cap fromthe bottle, and to then screw the member 6 onto the threaded neck of the bottle. Then the bottle is inverted and the feed device is inserted downward in the member A, in the manner shown in the drawings, and the pin 21 is brought into engagement with the notch 22, whereby the machine is then ready for use. When the bottle is empty, it is removed with the feed device, and the latter is unscrewed and placed on anOther or fresh bottle. The base B, it will be seen, is provided at one side thereof with a notch or recess b to receive the cup or glass G when it is desired to draw off a portion of the contents of thebottle. Thebase B is preferably heavy enough to hold the machine upright, and against tipping over, and with the provision of the notch or recess b the glass or cup will rest on the table or counter upon which the machine is placed.

What I claim as my invention is 1. A machine for dispensing powdered materials, such as malted milk, by disharging measured quantities fromthe original bottle in which the, product is sold, comprising a cup having an upper internally threaded portion to receive the threaded neck of said bottle, so that the bottle will be supported upside down, with a shoulder extending around the bottom of said threaded portion, a plate formed'to provide a feed opening and having its edges supported on said shoulder to be clamped thereon by the mouth of said bottle, the bottom of the cup having an outlet disposed out of register with said feed opening, a central shaft extending upward through said cup and into the neckof said bottle, a feed wheel mounted on said-shaft to rotate in said cup below said plate and provided with blades forming pockets between them to feed measured quantities of the product from said feed opening to said outlet, means on said shaft for stirring the product in the neck of the bottle, a ratchet mechanism on the lower end of said shaft, below the cup, to intermittently rotate said shaft, a horizontally movable lever to operate said mechanism,

means on the bottom ofsaid cup to limit the lateral swing of. said lever to insure the a and means to support said ring in elevated position, w th space below for a glass to receive the discharge after each operation.

2. In a machine for dispensing powdered materials, the combination of a structure as specified 1n claim 1, and a valve pivoted on and means on the bottom of said shaft to control said outlet, said valve being rigid with said lever.

3. In a machine for dispensing powdered materials, the combination of a structure as specified in claim 1, and a flexible scraper on the upper end of said shaft, adapted to scrape the sides of said bottle, being flexible to permit insertionof the bottle in said cup and removal therefrom.
