SPECIFICATION forming part of Letters Patent No. 302,420, dated July 22, 1884.
v I Application filed December 1, 1883. (No model.)
To aZZ whom it may concern.-
Be it known that we, J OHN MCKEAGE and \VILLIAM \VELLs, of Brooklyn, Kings county, New York, have invented a new and Improved Mixingdllachine, of which the following is a full, clear, and exact description.
lhis invention seeks to provide an effective machine for mixing flour, grain, and similar substances; and the invention consists of the several combinations of parts, substantiallyas hereinafter fully set-forth, and pointed out in the claims. I
- Reference is to be had to the accompanying centrally through it from end to end and from opposite corners, so that the ends of the body stand at right angles to the shaft, while the sides of the body are diagonal thereto in all directions, as shown. The shaft B is hollow,
. and is held fast in the uprights G G, and constitutes the feed and discharge conduit of the apparatus, being provided at one end with the hopper G and formed at the other with the discharge-opening H, and formed withinthe body Awith the outlet-opening I and hopper J, and in the hollow shaft B areplaced the feeding and discharging worms D D, formed or placed upon the shaft E, which is passed through the shaft B and journaled in the closed ends thereof, and also in the plates or partitions FF. placed in the hollow shaft B, as
shown in Fig. 1. r i
In operation the material to be mixed-two grades of flour, for examplewill be fed into,
the hopper G. The body A will be revolved upon the shaft B byabelt coming from a suit ing from a suitable power passing over the pulley M. cause worm D to convey the material from hopper Gr along the hollow shaft B and disp charge it through opening I into the body A. In revolving, the body A, owing to its shape, has a peculiar wabbling gyratory action, and this motion of the body causes the material inside to be tumbled from side to side and end to end of the body, causing it to be thoroughly agitated and mixed. On reaching the discharge end of the body A, the material will The revolution of the shaft Ewill be lifted by the buckets N, which are secured to the inner sides of the body A, and emptied from the buckets as they successively reach the point immediately above the shaft B into the hopper J, from which it willbe conveyed along the hollow shaft B to and out of the opening H by the (liscl1ai-ge-\\-'or1n D in a thoroughly mixed condition.
To prevent any clogging of the material in the hopper G, we provide the hopper with the agitator O, which is given a constant lip-anddown movement from the eccentric l, secured upon the shaft .15, to which eccentric the agitator is connected; and in order to break up any lumps or aggloinerate masses in the material being treated we place within the body A the-disintegrating-screens Q, against which the material is thrown and through which it must pass. 7
R is an opening, closed by a suitable cap or door, through which any material remaining in the body A may be discharged, or through which the body A may be fed or charged with material to be mixed in case the automatic feed is not used; and upon the shafts BE are placed the loose pulleys S 'l, to which the belts may be shipped when it is desired to stop the action of the apparatus without stopping the power.
To the-end and corner of the body A opposite to that to which the casting L is secured is secured the casting L, which formsa journal for the body A on shaft B, as will be understood from Fig. l; and suitable collars may be formed or secured upon the shaftB outside of casting L and pulley S, to prevent all dander of endwise movement of body A upon shaft B.
Constructed in the manner described, it will be seen that the apparatus is self-feeding and self-discharging, so that it is thus adapted for continuous operation, and it will also be seen that, owing To the shape and action of the Patent- 1. In a mixing-machine, the combination, with the stationary tubular shaft and the wormshaft, ofthe hollow body having the subdividing-screens, said body having near one end buckets, and said tubular shaft having a 110 per outside of the body, and an outlet inside near one end of the body, and a hopper inside near the opposite end of the body, and an out let outside of the body, substantially as and for the purpose set forth.
2. In a mixing-machine, the Combination, with the right and left handed feeding-or Worm shaft and the stationary tubular shaft, of the hollow body having buckets on its inside near one end, and transversely subdividing screens extending from side .to side of the body, said tubular shaft having a hopper outside of the body, and a discharge-opening inside of the body near one end, and a hopper inside of the body near the opposite end thereof, and a diseharge'opening outside of 'the body, substantially as shown and described, and for the purpose set forth. i JOHN MoKEAGE.
