MIXING APPARATUS.

Application filed August 17, 1925. Serial No. 50,537.

The present invention relates to mixing apparatus of the type especially adapted for mixing beverages. It is to be understood,

however, that the apparatus may be used for nation of the liquid placed therein. Another.

object is to provide an apparatus capableof thoroughly and quickly mixing the l quids or fiuidic materials placed therein by violent agitation. A further object is to prevent the violently agitated liquid from sloppmg or spilling. A. still further object is to pr o vide means for quickly attaching the liquid containing receptacle to and removing it from the mixing device.

In order to achieve these and other objects, I provide an apparatus which has but one moving part in contact with the liquid, and that part, preferably, has no hearings or journals into which the liquid might penetrate, and which'would have to'be taken apart for cleaning. This moving part is preferably a flexible diaphragm, forming a portion of the wall of the container or receptacle, and is caused to vibrate, by outside forces,'to set up pulsating currents in the liquid within said receptacle.

Amore complete description of a preferred embodiment of the invention will now be given, with reference to the accompanying drawings, wherein Fig. 1 is a part sectional elevation of the complete mixing apparatus.

3' Fig. 2 is a detailed end elevation, enlarged, ec'centrically mounted pitman ends. p

Fig. 3 is a vertical section of one of the receptacles with its mounting.

Fig. 4 is a plan view of the receptacle.

Fig. 5 is a sectional plan taken on the line 5-5 of Fig. 3. A Fig; 6 is a vertical section of a modified form of receptacle. In the drawings, the reference numeral 1 designates a liquid containing mixing vessel or receptacle, which may be made of glass, metal, or any other suitable-material, and is preferably formed with circular 'cross section and outwardly flaring sides, as shown. The bottom of the receptacle 1, as shown in Fig. 3, is a flexible diaphragm 2, formed of rubber or other suitable material, which is preferably removable, and mounted in any convenient manner. For example, I have shown said diaphragm 2 as having its peripheral edge set or clamped in aring 3, preferably metal, and said ring is clamped between a shoulder at formed upon an annular flange 5 secured to the lower portion of the receptacle and a plug member 6 screwed into said flange. Thus by unscrewing said plug member, the diaphragm 2 may be removed for cleaning or replacement, and when said diaphragm is in place, and the plug member screwed home, the entire assembly forms a liquid containing receptacle with a flexible bottom.

Above the flexible bottom or diaphragm 2, the receptacle 1 is provided with a partition or false bottom 7, which may be removable for cleaning, if desired, and may be secured in the position indicated in Fig. 3 by any suitable means, not shown. The false bottom 7 is formed with apertures 8, Figs. 3 and 5, to permit the liquid to pass through it, and above said apertures are positioned baflies or deflectors 9 which cause the liquid passing upwardly through the apertures 8 to enter the receptacle 1 with a swirling or tangential motion, as indicated by the ar-.

rows in Figs. 3 and 4. For this purpose, the deflectors 9 are closely contiguous to the receptacle wall at 10, and to. the false bottom at 11, their ends 12 being open to allow the fluid to passthrough. v

It will be readily understood that, if the receptacle 1 be partially filled with liquid, and the diaphragm 2 be rapidly vibrated, by any suitable outside source, said liquid will be violently agitated, and on account of the positioning of the apertures 8 and the deflectors 9, that h'eli cally and upwardly directed pulsating currents will be set up in said liquid, as indicated by the arrows in Figs. 3 and .4, thereby causing a. complete 1 I may provide some suitabledeflecthg means, as for example a series of inclin baffles 13, Figs. 3 and 4, secured to and pro- Fig. 2.

jecting inwardly from the wall of said receptacle near its upper end, such baffles being positioned to re-direct the ascending helical current in a downward direction.

The bottom' plug-member 6 is provided with a neck 14 and a bottom flange 15, the latter serving as a base upon which the receptacle may stand. The neck 14 is hollow, and preferably interiorly tapered, as shown in Fig. 3, to adapt it for separable connection with the means for vibrating the diaphragm 2. Although any suitable means may be employed for vibrating said diaphragm, I prefer to use a pulsating air current, and as a preferred means for supplying such an air current, 'I have shown the apparatus illustrated in detail in Figs. 1, 2 and 3.

An electric or other motor 16, Fig. 1, is housed within a suitable casing 17, which may be vented as shown at 18. The top 19 of said casing is preferably secured directly to the motor 16, as shown at 20, to insure rigidity, and is provided with one or more flanged cap members 21, there being two such cap members shown in Fig. 1. A flexible diaphragm 22, formed of leather or other suitable material, is placed beneath each cap member 21, the edge portion of said diaphragm being clamped between said member and the casing top 19. Each diaphragm 22 is connected by a pitman rod 23 with an eccentric 24 mounted upon the shaft 25 of the motor 16. The connection between the diaphragm and the pitman rod is preferably made by means of two rigid plates or washers 26 secured to said rod and clamping the central portion of the diaphragm between them." A spring 27 Fig. 3, may be inserted between the diaphragm 22 and the cap member 21. Each eccentric 24 is preferably provided with a ball hearing 28 for the pitinan rod end, as shown in The cap members 21, one of which is shown in section in Fig. 3, are formed with upstanding tubular nipples 29, exteriorly tapered to fit-within the necks 14 of the receptacle bottom members 6. Thus when a receptacle 1 is fitted upon one of the nipples 29, as shown in said Fig. 3,*it is not only held firmly in upright position, but a communicating passage is established between the chamber-30 below the receptacle diaphragm 2 and the chamber 31 above the power diaphragm 22, so that, when the latter is vibrated by the motor 16, acting through the pitman rod 23, a 'ulsatingair current is caused to act upon t e bottom of receptacle diaphragm 2, causing it to vibrate and so agitate the liquid contained within the receptacle 1 as described above.

I have shown in Fig. 6 a slightly modified form of device embodying the principles of my invention. In this construction, the receptacle diaphragm 2 is mounted in a chambered member 32 positioned to one side of the receptacle 1, and connected therewith by a tubular nipple 33, the bottom ring or flange member 5 of said receptacle having a tight and rigid bottom 34. The chambered member 32 is extended upwardly in the form of a handle 36 which may be grasped conveniently, and whose upper end is connected with the receptacle 1 by a brace 37, as shown. of the device is exactly like that of the previously described form, the vibrations of the, diaphragm 2 producing pulsating currents in the liquid'within the chambered member 32, which currents passing into the bottom of the receptacle 1 through the nipple 33, are directed by the deflectors 9 in ascending helical paths as before. 7
