Application ined December 2o, 192s, serizl no. 681,711.

This invention relates to acombination lime hydrator and mortar making devlce and has special reference .to themaking of complete dry mortar such as used forplastering or the like. Y

The principal object of the invention isl to provide a simple and compact machine for the production of a `finished dry mortar product from vhydrated lime, the same being accomplished simultaneously with the'hyl dration of the lime.

Another object of the invention is the` provision of means whereby either hydrated lime or dry mortar may be made with the machine, or the latter product accomplished by the machine without simultaneous hy dration of the lime as desired.

@ther objects and advantages of the invention will appear in the further description thereof.

Referring now to the accompanying drawings forming part of this application:

igure 1 is a side elevation of the-upper half of the machine, partly broken, away, showing the lime hydrating apparatus and the hopper in which the ,other materials are added when the machine is used in the manufacture of mortar; and

Figure 2 is a similar view of the lower part of the machine, showing the conveyors,

dii

cooler, elevators, etc.

Referring particularly to Figure 1 of the drawings the stack of the hydrator is shown at 1, and the weighing and charging apparatus at 2, through which the material is weighed and fed to the hydrator or primary mixer. A water supply is also provided in any well lmown manner, it not being considered necessary to illustrate the same here, as this form of lime hydrator is old in the art.

IThe mixer proper is illustrated at 3, vfor the interior construction of which and the arrangement of stirring devices thereof, reference is had to myv former United States Patent No. 1,398,238 of November 29th, 1921; all the objects and advantages of which are derived in theinvention. A suitable driving mechanism is provided such as illustrated at 4 for rotating the mixer, and the operation and control of the interior mixing devices may be readily elected by the control mechanism illustrated at 5.

e mixer 3 is mounted upon the rollerA bearing base 6 supportedupon a suitable `I have shown the hopper 18 supported by fabricated ysteel basev or bed 7 `which rest upon a floor 8.

Concentrically below the base 6 and below the floor is the hopper or bin 9, the same being provided at its lower end with a suitable feeding device 10, the' office of which is to feed the material being mixed to the cooling drum 11 in the proper quantities; the base of the feeding device being of course connected in any suitable manner to the upper end of the cooling and mixing drum. This drum is provided with a cen-fl tral longitudinal shaft 12 the lsame having securely xed'thereto a ynumber of paddles or mixing blades 13, they being for the pur,- pose of further mixing and a itatin the material as it slowly passes t rou the cooler, and the-shaft 12 is provided lwith any desired means for rotation, for example the pulley and gear connection indicated 15 which leads through a pulverizer and air separator, of any suitable type, such as indicated at 16, and the other end of the conveyor 15 communicates with a bucket elevator 17, which may lead to a baggin machine, or bins for storing of the materia To provide for the ,manufacture of mortar,

the floor 8 in which the desired additional material such as hair and the like are placed.

In 'the lower end of the hopper is installed any form of agitator 19 through which the material must pass to the feeder 20, the same being directly connected to said hopper.

The feeder 20 is for the purpose of regulating the amount-of materials passing therethrough in the right proportion with the amount of hydrated lime passing through the feeder 10. The feeder 20 communicates with one end of the spiral conveyor 21 which v conducts the materials therethrough and empties them into the upper end of i the cooling drum 11 where th'e the lime hydrate and together pass through the cooler into the second conveyor 15 and to the bucket elevator 17, from thence to the place ofstorage.

'7s at 14. The material then passes from the lcooler 11 into one end of the'spvlral conveyor" are mixed with 10o The conveyor 15, as above described, also` communicates with the pulverizer and separator 16, said, communication being controlled by the slidel indicated at 22, so that when mortar is being made, the slide may be closed, thus forcing all of the material through the conveyor l5 to the bucket elevator l? but when h dreteol lime only 4ie being reduced the sli e @muy he opened,

thus a lowing the hydrate to drop into the aired.

lt is Well lrnown inthe ort that other material such as cement is sometimes incorpointed Within mortar and in which event it is obvious that the some may be supplied to the hopper 18 with the heir und in any desired quantities so that it, together with the hoirbecome thoroughly mixed during the travel ofthe conveyor 21 and then more thoroughly incorporated in the min ne it continues through the machine.

meneur lln the production of hydrated le only the conveyor Qi'may he shut oh', es no material would pass therethrough, and the regular process or hydration and air seperattion take place as previously described.

Having thus described my invention, what l claim and desire to secure by Letters Patent, is:

The combination with a, lime hydretor, ont ineens directly associated therewith whereby either hnished ldry mortar or dry' hydrated lime may be continuously supplied from seid means, and a, pulverizer intermedia-te of the mortar und hydrator discharges.
