provlsion of a protector of unique construction; which -is applicable. to .a drink mi-xing machine in I a simple and Q elfective manner,- for protecting r:or"envelopin| .2 the. agitator and agitator stetn,= when the-machine is at: normal or 'idlewcondlition;

It is also the object :of this inventiomlto provide a device of the? nature indicated, which will be automatic in itsfnatureg-whera hy thG PI'Oi'iBGtOI" proper will; be: automatically applied to and removed from theagi tator and agitator stem when the tumbler. or other vessel is removed fronnrandapplied to the machine; respeotivelyr- V It is: also -withinsth'e scope of the present invention to provide a protecting device for mixing 'machines. Whichwill be comparativel-y simple; light; non-encumbering and 1 inexpensive in construction; which may :be readily applied to a mixing :machine to! be operated automatically by the-i application-1 and removal of atumhiler or other-vessel=,-1. and which will be-simple, convenient, x-prac ticalaand eificientinits use.

With :the foregoing :and other objectsain view which will appear as: the description proceeds the invention resides in the combination and arrangementof parts: and :in thedetails of construction hereinafterdescribed i and. claimed, it: being understood that changes in'the precise embodimentdoffthe invention herein disclosed can be made; with r:

The invention has been illustratedinits:

preferred embodiment in the accompanying;

drawing, wherein Figure 1 is a .sideielevationwofithe device as app liedto: a .mivring..,machine, the-.partsi beinglrln normal-eposition. Fig. .2 isa front view ot the device-tin opened position-.- for permitting thamlxing machine to operate in the usual manner: Fig.3 is a sectional View takenon theline 38 of Fig-a1.

The mixing emachinedepicted in the drawlng, which-may beataken as conventional-lor typical, embodies the base 1 havinga ahollowstandard 2, into which is telescoped-='a standardisectionriv carrying a motor-4 at lts upper-endand-to one side-thereof. Thdarmatureof the motor i is pro-.

The present device, which -is in the form= of an attachment for \the: mixing machine, 7

embodies a pair oi U-clips 9 straddling orembracing thestandard or pedestal 2, and having their terminals connected byclamp-, ing ;boltsrl0, to hold therclips in place; The

intermediate portions of the-clips 9 are provided with .joutturned lips or flanges 11,

through .Which arejournaled -.a pair of rods: or rock shafts-l2 which are provided at their lower ends with rforwardly projecting curved tappets or fingers-13 disposed immediately .95 holder -7. The upper-endsof the rods 01 shattsi12 are loent-angularly forward; asat above tlieQjaWs-S 'ofi the-tumbler or glass 14, and carry the protector or sheath 15.

The protector orsheath 15 of tubular g .or upwardly tapered form, and is divided longitudinally into a palr of companion or complementing sections 16 having the outturned lips 17 along their edges, adapted to abut flatly when the sections 16 are swung together. The rear edges of the sections 16 of the protector or sheath are soldered or otherwise secured to the upper angular ends 14 of the rods or shafts 12 whereby the respective protector sections 16 will be carried by the rods or shafts 1 2. The lower end of one section 16 is provlded with a disk 18' adapted to fit into the lower end of the other section 16 when the sections are folded or swung together, to close the lower end of the protector.

A pair of coiled wire springs 19 are mounted upon the rods or shafts 12 below the upper lip 11, and are terminally engaged to the said lip and rods or shafts 12, to yie1dably swing the rods or shafts 12 in such a direction as to normally tend to swing the sections 16 of the protector together;

In practice, the device may be readily attached to the mixing machine as will be ob vious, and the parts of the device or attachment are so arranged, that ordinarily, when the standard section 3 is raised (the member 3 being usually raised by means of a spring) so as to raise themotor 4 and the agitator 6 and its stem 5, the sections 16 will be swung together under the influence 0f the springs 19, to fit snugly together so as to surround the agitator 6 and its stem 5 to completely envelop and protect the same from dust, insects, and other foreign matter. The upper end of the sections 16 embrace the upper portion of the agitator stem or spindle 5, to close the upper end of the protector 15, while the end piece 18 carried by the lower end of one section 16 closes the lower end of the protector. Now, when the machine is to be brought into operation, the tumbler, glass or other vessel, 20 being snapped into or seated within the jaws 8, will strike the tappets or fingers 13, and will swing them apart and rearwardly, and as a result, the protector sections 16 will be swung apart and opened, as seen in Fig. 2, to enable the motor 4 to be depressed therebetween without interference. In this manner, when the tumbler or other vessel is applied to the machine, the protector will be opened, and the motor may be reciprocated vertically to depress the agitator 6 into the tumbler, or to raise the agitator out of the tumbler, when the tumbler is to be removed. As soon. as the tumbler is removed, the tappets 15 will be released, and the agitator and agitator stem having been previously raised with the motor 4 and the standard member 3, will cause the sections 16 of the protector to swing together so as to surround the agitator and agitator stem while they are in idle or inoperative position.

The present device is therefore entirely automatic in its operation, and will not inconvenience the use of the mixing machine in usual mode, but on the other hand, the present attachment will render the use of the mixing machine more convenient, inasmuch as the agitator and agitator stem will be protected against dust, insects, and other foreign matter, while the machine is in idle or normal position. This will eliminate the necessity of the repeated cleaning of the agitator and its stem.

From the foregoing, taken in connection with the drawing, the other advantages and capabilities of the present invention will be obvious to those skilled in the art, without further comment being deemed necessary. 7

Having thus described the invention, what is claimed as new is 1. The combination with a mixing machine including an agitator, of a protector for the agitator including separable sections carried by the machine and adapted to be swung to and from each other.

2. The combination with a mixing machine including an agitator, of a protector for the agitator including separable sections, and means for moving the sections to and from each other.

3. The combination with a mixing machine including an agitator, of a protector for the agitator including separable sections, and spring pressed means for normally holding the sections together to inclose the agitator and including a tappet adapted to be moved for separating the sections.

4. The combination with a mixing machine including an agitator, of a protector including separable sections, and oscillatory members carried by the machine and carrying the said sections.

5. The combination with a mixing machine including an agitator, of a protector including separable sections, and spring pressed oscillatory members carried by the machine and carrying the said sections, said oscillatory members having means for actuating them to separate the said sections.

6. The combination with a mixing machine including an agitator, of a protector including separable sections, and spring pressed oscillatory members carried by the machine and carrying the said sections, the said oscillatory members having tappets adapted to be actuated by a mixing vessel to separate the said sections.

7. The combination with a mixing machine, including an agitator, of a pair of rock shafts carried by the machine having tappets to be engaged by a mixing vessel,
