DENNIS JIREAUME, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF TO JOHN HOLTZ. OF DETROIT, MICHIGAN.

AGI'IATOR.

To all whom it may concern:

Be it known that I, DENNIS J. REAUME, a citizen of the United States of America, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Agitators, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates generally to a mechanism for stirring or agitating materials of various kinds, and particularly to a device of this character especially designed for use in making butter, but it will be obvious from the following description that it may be put to other analogous uses, as may be desired.

The invention consists in the construction of the device, in the peculiar arrangement and combination of parts, and in certain details of construction, as will be more fully hereinafter described and pointed out in the claims.

In the drawings,Figure 1 is a vertical central section through an agitator embodying my invention; Fig. 2 is a sectional perspective view of the top of the device, illustrating particularly the driving means; and Fig. 3 is a detail sectional perspective, showing the retaining means for the cover.

In the drawings thus briefly described, A represents a suitable receptacle, in this particular instance a glass vessel, formed at its upper end with a neck section B.

G are inclined ribs upon the neck portion that are adapted to form a retaining thread, and D .is the closure for the receptacle. The closure D, as shown, is made up of a plurality of sections. Thus, D is a ring member," angle-shaped in cross section, adapted to be screwed upon the neck portion of the receptacle, the ring carrying depending lugs E that engage the screw-threads C. Upon the inner edge of the ring described is formed an annular series of teeth F, which constitute an internal gear adapted to mesh with pinions hereinafter described carried by the heaters.

F is a disk or plate mounted upon the ring D for rotary movement.

G is an inner disk formed with an annular recess H extending about its periphery, and with complementary semi-circular recesses H in which the beater pinions are adapted to be seated. This disk is rigidly attached Specification of Letters Patent.

to the disk F in any suitable manner, as by bolts I.

WVithin the receptacle described is a stirrer J, so fashioned as to extend from the top to near the bottom of the container and crosswise from side to side in proximity to the walls. In construction, the stirrer is preferably in the form of a frame made up of a central spindle or shaft K, of polygonal cross section, rigidly attached to the disk F of the closure, a cross bar L fixed upon the lower end of the central spindle, and side members M and N in the form of independently rotatable spindles uniting the cross bar with the closure. These complementary spindles are swiveled at their lower ends to the bar L, project upwardly through the disk G within the semi-circular recesses, and carry at their upper ends gear pinions Q, that mesh with the internal gear F. P are smaller disks secured one upon each spindle to bear against the under face of the disk G. The lower cross bar L described terminates at its ends in blade members a, while the central spindle K, and each of the side spindles is provided with a series of beater blades, as O, the several groups of blades being adapted to interengage in the manner indicated in Fig. 1.

In the operation of the device, the stirrer proper is removed with the closure from the receptacle, and the material that is to be agitated placed therein. The closure is then screwed upon the vessel, and through the agency of a handle, as R, the disk F rotates. This carries the stirrer frame in its entirety, causing the latter to rotate within the receptacle, giving the entire mass of material therein a circular movement, and at the same time, through the fixed internal gear, the side portions of the frame, constituting the heaters, independently rotate, and in directions opposite to one another. In this manner all of the material within the receptacle is intimately mixed or agitated in a thorough and effective manner and within a minimum space of time.

What I claim as my invention is:

1. In an agitator, the combination with a receptacle, of a closure comprising a stationary and a rotary member, a central spindle fixed to one of said members, spindles arranged upon opposite sides of said central spindle and journaled in said last-mentioned member, beater arms upon said spindles and means carried by one of said closure members for causing the simultaneous rotation of the side spindles.

2. In an agitator, the combination with a receptacle, of a closure comprising a member having a fixed engagement with the receptacle and a rotary disk, a stirrer secured to said disk, and a drive connection between i rece tacle of a closure com risin a rin b t) "he receptacle, and means carried by and tachable with the closure for imparting centrifugal movement to the vessel contents, and mechanism for stirring portions of the revolving mass in directions opposite to the centrifugal movement.

In testimony whereof I afiix my signature in presence of two witnesses.
