AGITATING DEVICE.

Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed February 13, 1920. Serial No. 358,365.

State of \Visconsin, have invented certain new and useful Improvements in Agitating Devices, of which the following is a specification. 1

This invention relates to agitating devices and more particularly to devices for hydrating lime and has for one of its objects the provision of a device of this character 'Wltll improved means of operation.

Another object is to provide a device of this character that may be used for mixing any plastic materials and having improved means for discharging the mixed material. 'A further object is to provide a device of this class that will have means for simultaneously operating the several parts.

These and other objects such as simplicity, durability, cheapness in manufacture and the general improvement of the art will be more fully brought out in the folings the numeral 1 designates the base of my device having a square member 2 secured in its center. A circular bearing ring 3' is mounted in the member 2 and a circularsupporting member 4: is mounted in the center of the ring 3 and held in place by braces 5. The members 2, 3, 4, and 5 may be separate pieces or may be cast as a unit as desired.

The bearing ring 3 has a groove 6 formed in its upper surface and ball-bearings 7 are mounted therein.

A center tubular support 8 is secured the member 1.

A pan base 9 has a center opening 10 and a bearing ring 11 surrounding said opening. The bearing ring 11 is adapted to fit within and over the bearing ring 3 and rest on the ball-bearings 7 The pan is provided with sides 12 which are bolted to the base 9.

a A tubular member 13 of equal height with the sides of the pan and the same diameter as the opening 10 is mounted over and adapted to closethe opening 10 and is raised and lowered by mechanism hereinafter described.

A circular supporting member 1% is mounted on the support 8 and cone shaped The lower porcap 15 is secured thereto. tion of the sides of said cone shaped cap being vertical and overlapping the member 13. V V

A cover 16 is secured to the sides 12 of the pan and has an opening 17 in its top center. a

A plurality of plow beams 18 are secured to the cap 15 and have a plurality of plows 19 secured in sockets 20 formed thereon.

The member 13' is' mounted on a ring 21 having arms 22 mounted in a ball-bearing mounting 23 in a band 2 l-slidably mounted on the tubular supporting member 8.

A plurality of discharge scrapers 25 are mounted in the pan and have their forward ends supported by braces 26 secured to one of the plow beams 18 and their rear ends supported by operating mechanism comprising a'link 27 connected to one end of a crank arm 28 supported in bearings 29 on member 1 1; the other end of the crank arm end bent inwardly on an angle at 32 and are mounted in a guide 33 having a roller bearmg 3 1. The guide 33 being mounted on the cap 15. A guide roller 35 is also mounted onone of the plow beams 18 adjacent the I beam to prevent outward movement.

A shaft 36 having an operating handle 38 is revolubly mounted in the base 1 and extends into the member 8 and has an eccentric connection with a link 37 which is connected to levers 38. The levers 38 extending through slots 39 in the member 8 and being connected with the band 24.

later is admitted through pipe 40 which is connected to a sprayer 41.

A gear member 42 is mounted on bottom of the pan base 9 and is in operative engagement with a gear 43 on a stub shaft 44 journaled in the base 1. A driving pulley is shown on the shaft as but the shaft may receive its power in any manner and from whatever source desired.

The operation of the device is as follows: The device being assembled the material is put in at the top through opening 17 and falls on the cone 15 thus being evenly distributed, The power is then applied and the pan rotated, the plows and scrapers remaining stationary. When thematerialis sufiiciently vmixed the operator grasps the operating handle 36 of the shaft 36 and turns it thus imparting an upward motion to the levers 38 which raise the band 24; and the member 13. The band being connected by links 30, crank arms 28, and links 27 to the scrapers, the scrapers will be forced down as the band rises. The angle portion 32 of the I beams 31 will by contacting with the guide member 33 force the scrapers 1nwardly as they are forced downwardly thus discharging the material through the opening 10 in the pan base 9.

By returning the shaft 36 to its normal pos'ition'the operator will lower the member 13 and raise the scrapers and'the device will be ready for a recharge.

While I have shown and described the preferred embodiment of my invention, it will of course be understood that I reserve the right to make such" changes in the form,

I construction, and arrangement of parts as said opening, and means for simultaneously.

elevating said closure shell and lowering said scrapers into engagement with material within the pan. 7

2. A device of the character described comprising a base, a mixing pan rotatable upon said base and having its bottom provided with a central discharge opening, a cylindrical shell normally seating about and forming a closure for said opening, a plurality of stationary plows within said pan, discharging scrapers in said pan adjacent said opening, means for simultaneously elevating said closure shell and lowering said scrapers into engagement with material within the pan, and means automatically operating upon lowering of said scrapers to move the latter toward said discharge opening,

8. A device of the class described comprising a base, a mixing pan having a discharge opening in its bottom, said pan being revolubly mounted on said base, a tubular support mounted in said base and extending upwardly through said discharge opening, a closure for said discharge opening slidably mounted on said tubular support, a plurality of plows rigidly mounted within said pan, a plurality of discharging scrapers movably mounted within said pan and normallyheldout of engagement with the material being mixed, and means for simultaneously raising said dischargeopening closure and bringing said scrapers in engagement with the material being mixed.

4:. An agitating device comprising a base, a mixing pan having a discharge opening in its bottom, said pan being revolubly mounted on said base, a tubular support 'mounted in said base and extending upwardly, through said discharge opening, a closure for said dischargeopening slidably mounted on said tubular support, a plu rality of rigid plow beams mounted within said pan, a plurality ot plows removably mounted onsaid plow beams, a plurality of discharge scrapers movably mounted within said pan and normally held out of engagementwith the material being mixed, means for simultaneously raising said discharge opening closure and for bringing said scrapers in engagement with the material being mixed, and means for revolving said pan. 7

In testimony whereof I hereto afiix my signature. c
