Specification of Letters Patent.
Patented Feb. 27, 1912.
Application filed March 14, 1910. Serial No. 549,136.
agitating devices of novel construction and arrangement adapted to insure a thorough commingling of materials introduced therein, allas will more fully appear hereinafter.
In the accompanyin drawings z--Figure 1 is a side elevation; Fig. 2, a. plan view;
Fig. 3, a cross section taken through the `mixing drum (Figs. 1 and 2); Fig. 4, a
transverse section through the mixing drum; Fig. 5, a diagramshowing the mixing blades l or vanesdeveloped.
The mixer is carried by any preferred form of wheeled or other truck 1 having any preferred form of motor, in the present instance, a steam engine 2. Rising from the truck 1 are the bearing standards 3 which are provided with removable caps or plates 4 connected by bolts 5 thereto. A plurality, preferably three, as shown in Fig. 1, of rollers 6 which are provided with axles 7 journaled in the plates 4 and bearing standards 3, constitute a roller bearing for the tubular trunnions 8l of the mixing drum or cylinder 9, the parts being so disposed that the drum or cylinder 9 lies as close as possible at its lower part to the surface of the ground, so that it may be the more readily fed with the material to be mixed and the mixed material may be the more readily taken oit. A chute or hopper 10 supported by a bracket 11 (Figs. 1 and 3) has its inner end passed loosely through one of the trunnions 8 so as to conveniently deliver the material to the interior of the drum or cylinder. On the other side of the machine there are brackets 12 to which is hung by a rod 13, a discharge chute 14, which normally lies in the position shown in F ig. 3 4when it is not desired to discharge the contents of the drum 9, but when said contents are to be discharged, this chute or spout 14 is tilted so that its outer end is lowered and the mixed material instead of then falling -back into the drum, is delivered onto the chute and is discharged close to thesurface of the ground.
The drum contains three internal circularly arranged series of blades of which the rows containing the blades 15 and 16 are mixing blades and the remaining row is composed of shifting blades 17 and mixing blades 18 which are arranged in alternation, the mixing blades 18 being curved as will more fully appear from Figs. 3 and 5, while the remaining blades 15, 16 and 17 are inclined and may be slightly dished if preferred. 'Ihe blades 15 overlap the blades 16 "and the latter overlap the blades 17 and 18.
The general disposition of the blades 17 and 18 is angular to that of the blades 15 and 16. As a consequence of this construction and arrangement, the rotation of the drum causes the blades 15 and 16 to lift and agitate the material which has entered the drum through the chute or hopper 10, but to tend to direct it back toward said chute or hopper, thus the more thoroughly insuring mixing thereof. The shifting blades 17 being oppositely or angularly disposed in relation to the blades 15 and 16, shift the mixed material and tend to throw it back on said blades 15 and 16, the mixing blades 18, b v reason of their curvature tending to keep the material from passing to the outlet side of the drum and scooping up the material and letting it fall backward, and thus a most thorough mixing is effected.
The operating shaft of the motor is connected by chain and sprocket gearing 20 to a countershaft 21, which in turn, is connected lby chain and sprocket gearing 22 to the gear 19.
Having thus described my invention, what I lclaim asnew and desire to secure by Letters Patent, is
In a mixing device, a rotatable drum having secured to its interior peripheral wall near its inlet two overlapping sets of staggered mixing blades, said blades extending in parallel planes,' a third set ofv parallel blades at its discharge end and extending in planes at an angle to those of the two mentioned sets, and a set of laterally' curved blades alternating with those of the third set and adapted to return the material being mixed to the inner one of the two sets.`
