GBAIN-ROASTING DRUM.
Application filed March 13, 1924. Serial 1T0. 699,141.
To all whom'it may concern: i In order'that the invention may be more Be it known that I, WALTER JAMES RUsfully understood I will now give a short de- SELL, a subject of the King of Great Britain scription of the drum mountings and other and resident of the city of Winnipeg, in the parts associated therewith. 1 Province of Manitoba, Canada, have invent- To the side of the drum an upright post 3 I ed certain new and useful Improvements in is located and on this post a sleeve 1 is rotat- Grain-Roasting Drums of which the folably mounted, the sleeve providing a passage lowing is the specificat1on. 5 around the post which communicates with The invention relates to improvements in a pipe 6 which opens through a cap 7 to the 10 roasting drums and particularly to drums interior of the drum, the cap being perma for roasting all classes of grain, rye or nently secured to the side of the drum and barley including barley malt: and caramel rotating in the upper end of the pipe. A malt and an object of the invention is to pro driving shaft 8 is secured tothe side of the vide means in the drum for stirring the drum and extends through the cap and the 15 grain within the drum so that the same will upper end of the pipe into a bearing sleeve be evenly roasted, and to construct thest-ir- 9 formed integral with the upper end of the ring means such that it can be readily intropipe. The outer end of the shaft 8 is fitted duced into existing drums and at comparawith a bevel gear 10 which meshes continutively small expense. ously with .a bevel pinion 11 rotatably With the above more important objects mounted on the post. The, gear 11 is proin view'the invention consists essentially in vided with under teeth 12 which engage with the arrangement and construction of parts a bevel pinion 13 carried by a shaft 1 1, the hereinafter more particularly described, reflatter shaft'being fitted with tight and loose erence being had to the accompanying drawpulleys 15 and 16 and being provided with a ings in which: hand-wheel 17 A driving belt 18 operates Fig. 1 is a plan view of a grain roasting on the pulleys 15 01"16, the belt driving the apparatus and showing my invention ingears when on the pulley 15 and running stalled in the drum thereof. free when on the pulley 16.
Fig. 2 is an enlarged detailed vertical sec: The side of the drum remotefrom the tional view at 2-2 Fig. 1. shaft 8 is rotatably mounted on a shaft 19,
Fig. 3 is vertical sectional view at 8+3" the outer end ofwhich is carried by a car- Fig. 2. riage 20, the wheels 21 and 22 of which ride Fig. 4 is a horizontal sectional view at a horizontal curved track 23, the track bel 1 Fig. 2 and looking downwardly. ing concentric to the post 3. The shaft 19 In the drawings like characters ofreferis tubular and receives a testing tube 24 once indicate corresponding parts in the seV- which can be inserted within and withdrawn eral figures. from the interior of the drum.
The roasting drum 1 is of the ordinary According to the above arrangement it type being spherical in shape and provided will be obvious that the drum can be rotated with diametrically opposing doors or gates around its horizontal mas and that the said 2 and 3 such permitting of the insertion and drum can be laterally shifted to change its removal of the grain treated in the drum position from that as shown 1n Figure 1 to The drum is rotatably supported so that it a position above a plurality of gas or such can be revolved at comparatively high speed like burners 25 located within a heating is around a longitudinal axis positioned at chamber 26. The drum receives the grain or 9 right angles to the axis of the outlet open such like material to be treated whenan the ings 2 and 3, and it is further mounted so position shown-in Figure-1 and in this conthat it can be bodily swung inthe horizontal nection it is explained that the gram is putplane ninety degrees or thereabouts in order into the drum through an overhead spout to bringthe drum over a heater. (not shown), oneof the gates or doors being brought to the top and opened to permit the passage of the grain into the drum.
After the grain is introduced and the gate has been closed the drum is swung laterally into the heating chamber and is rotated by the belt and the grain or other material thereof is roasted while the drum is under the influence of the heat developed by the burners. After roasting, the drum is returned to the original position and the contents thereof are dumped through one of the gates into a receiving pan or tank 27, located on the floor.
In order to withdraw moisture and other floating material from the drum during the roasting operation, the drum is fitted with a pair of cylindrical screens 28 and 29 WlllCh open into the interior of the cap 7 and moisture and other floating material is drawn from the drum by suction through the pipe 6. Interiorly the drum is fitted also with a vertically disposed and centrally positioned spider 30 which carries radially disposed equi plates 31.
The device as hereinbefore described is now in use and I have found that the grain or other material roasted within the drum is not evenly roasted and that there is unnecessary time lost as the grain or other such material is not stirred to permit, not only of more effective roasting, but also of quicker roasting.
The wings which I provide are secured to the inner wall of the drum in any suitable manner and are now described in detail.
One wing 32 has one end thereof positioned adjoining one side of the door 3 of the drum and the other end positioned adjoining the opposite side of the other door 2 and it passes circumferentially within 'onehalf of the drum from side to side with the outer edge 33 thereof engaging the inner wall. of the drum and the inner edge 34: thereof Clearing the outer edges of the plates 31. The ends of the wing are fastened to the drum by angle brackets 35 and 36. The other wing 37 is similar to the wing 32 and passes circumferentially Within the other side of the drum and has one end terminat ing adjoining the same side of the door 3 as the other wing, and the other end thereof terminating at the same side of the door 2 as does the other end of the other wing. Both wings are slightly inclined in respect to the shell of the drum as best shown in Figure 2.
When the material is being roasted within the drum said drum rotates in a countersunk clock-wise direction, that is, in the di rection indicated by the applied arrow in Figure '1 and the inclination of the wings is such that they incline slightly towards the direction of rotation. When the charge is in the drum and the'sa ne is being rotated above the burners 25 the Wings act to gather the grain or such like material at the bottom of the drum and carry it up towards the top thereof, in the meantime stirring the same, and when the grain reaches the top it is thrown down on to the top of the grain lying in the lower side of the drum. This action of the wings constantly stirs the grain so that the same is subjected to an even heat and there is no possibility of any of the grain being burned. The roasting is accomplished more evenly and thoroughly and can be done much quicker than in the old type of drum where no such wings are used.
After the grain has been roasted and the drum has been turned back to its original position above the tank 27, the contents thereof are discharged through one or other of the doors, the door being opened after the same has been brought to the bottom of the drum. During the discharging operation the wings function further to aid in discharging the grain as they form interior chutes leading to the doors.
hat I claim as my invention is:
1. In a roasting drum having diametrically opposing entrance doors, opposing wings extending lnwardly from the inner wall of the drum and passing angularly thereacross.
2. In a spherical rotatably mounted roasting drum having diametrically opposing entrance doors, wings secured to the inner wall of the drum and passing thereacross in an angular direction with regard to the direc tion of rotation of the drum and having the ends of the wings terminated adjoining the sides of the doors.
8. In a spherical roasting drum, said drum having the ends thereof rotatably mounted and being provided at the sides with diametrically opposing doors, a pair of wings secured to the inner wall of the drum, said wings being positioned to stir the contents of the drum in the rotation thereof.
4-. In a spherical roasting drum, said drum having the ends thereof rotatably mounted and being provided atthe sides with diametrically opposing doors, a pair of wings secured to the inner wall of the drum and extending angularly thereacross and having the ends of the wings terminating adjacent the sides of the doors, the adjoining ends of both wings being positioned at the same side of the doors.
5. In a spherical roasting drum, said drum having the ends thereof rotatably mounted and being provided at the sides with. diametrically opposing doors, a wing passing around one-half of the interior of the drum from one side of one door to the opposite side of the other door and a wing passing around the other half of the drum from the latter side of the latter door to the opposite side of the former door.
6. In a spherical roasting drum, said drum having the ends thereof rotatably mounted and being provided at the sides with diametrically opposing doors, a Wing passing around one-half of the interior of the drum "from one side of one door to the opposite side of the other door and a Wing passing around the other half of the drum from the latter side of the latter door to the opposite side of the former door, both of said wings being inclined in respect to the drum body. 10
