MIXER Filed Jan. l5, 1934 Patented Sept. 3, 1935 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to mixers, and has special reference to mixers of the type useful in the operation of mixing beverages and other liquids; and objects of the invention are to provide an improved mixer having a motor provided with a vertical shaft, and an agitator operated by said shaft, said motor and agitator being supported by a bracket mounted for vertical sliding movements on and along supporting guides, which also function to limit extent of vertical movement of the bracket; to provide a device for supporting the bracket in a raised or elevated position; to provide a switch device for controlling supply of electrical energy to operate the motor; to provide a handle in connection with the bracket disposed between the supporting device and the switch device in such a relationship that the thumb of the hand engaging the handle may conveniently release the supporting device and also operate the switch; and to provide an agitator of novel construction.

Other objects and advantages of the invention will be apparent from the following description, reference being made to the annexed drawing, in which- Fig. 1 is a side elevation of my improved mixer.

Fig. 2 is an elevation at right angles to that of Fig. 1, a part of the supporting bracket being in section.

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1.

In the embodiment shown, the base I is designed and intended to support a container for the beverage-to be mixed. A vertical rod 2 has its lower end rigid with the base I. A rod 3 has a lateral extension 4 on its lower end and a similar lateral extension 5 on its upper end, said extensions 4 and 5 being rigidly attached to the rod 2 and constituting abutments limiting extent of vertical movement of the bracket that supports the motor and the agitator, while the rod 3 cooperates with the rod 2 to support and guide said bracket.

The bracket mentioned is made of a strip of metal bent to form a lower portion 6, an outer side portion 1, a top portion 8 and a downwardly extended inner portion 9 having its lower end forming a socket I receiving the reduced end I I of a handle I2 and attached to the arm 6 by a fastener bolt I3.

The arm 6 and the top portion 8 of the bracket have holes through which the rods 2 and 3 extend. Thus, the bracket is supported and guided in its vertical movements, extent of downward movement being limited by the extension 4 of the rod 3 and extent of upward movement be- :ng limited by the extension of said rod. An angular latch member comprising an arm I4 and a downwardly extended arm I5 is pivotally supported by the upper end of the rod 2 by a pivot I6 mounted in said rod 2 and extending through the arm I4 on the latch member. The lower end of the arm I5 is provided with a shoulder I1 designed and adapted to engage under the upper part 8 of the bracket and thereby support the bracket in its upper position. The arm I4 has an engageable portion I8 located in position to be conveniently engaged by the thumb of the hand that engages the handle I2 so as to release the latch device from the bracket.

A motor I9 is mounted on the arm 6 of the bracket and has a switch 28 located in position to be conveniently engaged by the thumb of the hand of the operator that engages the handle I2 so as to control supply of electrical energy to the motor through the wires 2|.

The motor shaft has a downwardly extended socket 22 receiving the upper end of a rod 23 releasably held in connection therewith by clamping set screws 24. The lower end of the rod supports a hollow conical agitator having numerous openings 25 through the wall thereof separated by members 26 having their lower ends integral with a ring 21. The agitator is a unitary structure and the conical upper end thereof is attached to the lower end of the rod 23.

Fig. 1 shows the bracket and the motor and the agitator in their lower positions, while Fig. 2 shows said parts in their upper positions.

From the foregoing the operation of the device should be apparent.

The construction and arrangement of the parts may be varied within the range of equivalent limits without departure from the scope of the appended claims.

I claim:

1. A device of the character described comprising a vertical rod, a bracket mounted for vertical sliding movements along said rod, a second rod supported by said first rod and holding said bracket from turning about said first rod and limiting extent of upward and downward movement cf said bracket along said first rod, a handle attached to said bracket for moving said bracket vertically, and an agitator device supported by said bracket.

2. A device of the character described comprising a vertical rod, a bracket mounted for vertical sliding movements along said rod, a second rod rigidly supported by said first rod and holding said bracket from turning about said rst rod and limiting extent of upward and downward movement of said bracket along said rst rod, a handle attached to said bracket for moving said bracket vertically, a motor supported by said bracket adjacent to said handle, an agitator device operative by said motor, and a control device for said motor operative by the thumb of the hand that engages said handle.

3. A device of the character described comprising a vertical rod, a bracket mounted for vertical sliding movements along said rod, a second rod supported by said rst rod and holding said bracket from turning about said rst rod and limiting extent of upward and downward movement of said bracket along said first rod, a handle attached to said bracket for moving said bracket vertically, a motor supported by said bracket adjacent to said handle, an agitator device operative by said motor, a control device for said motor operative by the thumb of the hand that engages said handle, and a latch device supported by said rod for supporting said bracket in an upper portion, said latch device being located in position for operation by the thumb of the hand that engages said handle.
