Speoioation of Letters Patent.

Patented Dec.I 1, 1914.

Application led'November 7,1913. Serial No.'799,788.

To all whom 'it may concern.:

Be it lmownthat "I, HENRY B. QUEAL, a citizen of the United States, residing at Kewanee, in the county of Henr and State of Illinois, have invented certain new and.

useful Improvements in Rotary Drinlc Mixers, of which the following is a full,

- buzz generally associated with electrically driven devicesis obviated; to provide an improved construction whereby the compressed air r as is yconducted to the impeller wheel o themixer inconspicuously and conveniently, and in which the spent gas, after doing its work, is conducted away from the impeller wheel quietly and inconof the valve a spicuously; to provide means for raising the agitator member out of the tumbler or receptacle containing the liquid without being obliged to lift the entire device; to provide a construction which will be suitable for all sizes of receptacles and all classes of liquids; to provide a construction which shall be simple mechanically, economical of construction, and which is not liable readily to get out of order; and in general to provide an improved apparatus of the character referred to.

Referring' to the drawings,-Figure 1 shows my improved drinkl mixer 1n side elevation, partsof the apparatus being shown broken away more clearly to show the mechanical construction of the device; Fig. 2 is a sectional plan of the casing along the line 2-2 of Fig. 1; Fig. 3 is a sectional view pted to control the air su ply; Fig. 4 is a perspective view of a mo 1- ed form of agitator button; and Fig. 5 is a cross-sectional plan of the agitator button shown'in Fig. 4. l

Similar f1 res refer to similar parts throu hout t e several views.' j

Re erring to the,d`rawings,-in Fig. 1, 1

is a hollow standard, preferably circular in cross section, provided wlth a tripod base 2.

` The baseY 2 is furnished with three softrubber'buttons 3, which prevent marring of the table or counter when the mixer as a whole is moved around. Upon the to of the standard 1 is rigidly attached a ho low casing 4, which is preferably Va circular casting with an integral boss 5, into .which fits the standard 1. The top of the casing 4 is provided with screw threads 5', to which is threaded a circular cover 6. The cover 6 AAand the casing 4 are of such a curvature that 'when the cover 6 is screwed onto the casing 4, a spherical construction results, with no projections to catch dust `or catch in the clothingof the o erator. The casing as a whole 1s provide with `a, spindle 7 loosely mounted therein in a vertical position. Loosely mounted upon the spindle 7 and in the center` ofthe casing is an impeller wheel 8, which has a hollow sleeve 9 projecting through the top of the casing and forming a bearin for the spindle 7. The sleeve 9 has a notc 10 of V-shape extendingacross the4 diameter of the top ofthe sleeve, and in thisy notch is a pinv 11 tightly fixed in the s indle 7 and projectingsligxhtly at each en On the upper end of tie spindle 7 is screwthreaded a linishing button 13, the latter being counterbored at its lower -end to admit the upper end of the sleeve 9. It will thus be seen that if the spindle 7 be lifted als vertically a short distance, the pin 11 will rise out of the V- haped notch in the end of the sleeve 9, leaving the impeller wheel 8 free to revolve without rotating the spindle.

Again, when the spindle is in its lowest ,o

sition, asshown in Fig. 1, if the impe er I wheel is rotated, the spindle will also revolve, due to the inlll coperatin with the notch 10 in the sieve of the impeler wheel.

Referring more particularly to the details of construction of the impeller wheel, upon the vsleeve 9 is fixed a strengthening collar 14' which carries the impeller wheel (proper 8. The latter is preferably stampe from a single piece of sheet-metal to form a series of radia ly extending arms 14', which carry a series of cone-shaped impeller blades or cups 15. I have found in ractice that the construction of impeller w eel just shown is particularly adapted for the resent con struction. Within the standar 1 is a supply pipe 16, the lower end of which isv connected as shown at 17 to a rubber hose 18 leading to anyrsuitable source of compressed air or gas. he upper end of the supply pipe d 16, as shown A1n Fig. 2, is soldered Qt otherwise xed -to the inside of the hollow standard 1, so that the supply pipe is located `as near to the circumference of the circular part ofthe casing 4 and the outer circumference of the impeller wheel as possible. At a point coincident with theA center of the impeller wheel is a nozzle orifice 19, the lips of which are so shaped as to deliver a jet of air or gas in such a direction as to coperate with the buckets of the impeller wheel to the best advantage. The top of the supply pipe 16 projects up through the closed top 20 of the casing lis boss, and the end of the pipe is bored out for a distance extending down below the nozzle 19 far enough to provide a bearin for the plug valve 21, which is a tube close at the top and open at the bottom, with a longitudinal slot" or valve port 22 which registers with the port 19 when the plug is turned in a certain position, thus admitting airor gas to the nozzle. To the plug 21 is fixed a stem. 23, which carries a handle 24, and leakage of gas or air is prevented 25'by the gland 25, provided with suitable packing and screwed onto the top of the tube 16. Adjustably mounted on the. outside of the standard 1, is a sliding bracket 26, which is furnished with a table 27 for supporting so the glass or receptacle 33 containing the liquid,'and a set screw 28 for adjusting and fixing the location of the bracket upon the standard. Upon the end of the spindle 7 is screwed an agitator button 29, which is approximately conical in shape and proend. rli`he exhaust lis thus inconspicuous andl practically noiseless.

1n Figs. and 5, l

which in some instances may be to the button shown 'in Fig. 1.

show a form ont button referable t will be 59 seen that the button 31 is substantially cylin- @5.0i the button. rli`he eii'ect of this is to prodrical in cross section and provided with notches 32, the latter being much deeper at the bottom than at the top of the button, and also being cut slantwise across the face vide a churning edect through the liquid,

and cause `a steady current` from the top to the-.bottom of the receptacle during the mixing operation.

,'lhe operation of the mixer is obvious from' the above description of its construction: The table 26 is adjusted upon the standard in such a position that when the spindle 's' is in its lowermost position, the

button 29 will be at the proper distance f iin-laste from the bottom of the glass to provide the'maximmn efliciency and greatest mixing edect. The glass 33 being full of liquid, it is necessary to raise the spindle 7 by pulling up upon the inishing button 13 a sufiicient distance to slide the glass under the agitator button I29, lthe upper position of the latter and of the shaft being shown in dotted lines on Fig. 1. l/Vhen the glass is'in place, thespindle 7 is lowered and mixing edected by opening the valve 24.

.The removal of the glass 33 is similarly eiiected by againv raising the spindle 7 high enough yto avoid interference with the agitator button 29.

1 do not wish to limit myself to the details of construction shown except as specified in the/appended claims.- v
