MIXING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 472,092, dated April 5, 1892.

Application filed April 8, 1891. Serial No. 388,160%- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM BRUMMEL WHEELER, a citizen of the United States, residing at the city of Madison, in the county of Dane and State of WVisconsin, have invented a new and useful Paint or Liquid Agitating or Mixing Machine, of which the following is a specification.

My invention relates to improvements in paint or liquid agitating or mixing machines, in which vertical rotating shafts journaled at the top and bottom ends are provided with horizontally-projecting arms or paddles; and the objects of my improvement are, first, to scrape any hard substance or sediment from the bottom of a barrel or tank and by a continuous action of currents and counter-currents to thoroughly mix it with a liquid; second, to agitate a liquid so as to facilitate its mixing with another substance, and, third, to be able to readily change the machine from one barrel or cask to another. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a left side view of the entire machine fitted to a barrel which is shown in section; Fig. 2, a plan of spider or upper frame of machine; Fig. 3, a side View of vertical shaft, showing ends of paddles; Fig. 4, a plan of gear h, showing square hole in center; Fig. 5, a vertical section of step and lower end of vertical shaft; Fig. 6, a section through line A B, Fi 2.

Similar letters refer to similar parts throughout the several views.

a is a socket or step provided with three or more downwardly-projecting points 5, which are to be driven into the bottom of barrel or tank '0, to which my machine. is applied and which forms the lower bearing for vertical shaft 0, directly above which bearing on vertical shaft are two concave double edged scrapers or horizontally-projecting arm's cl, that bytheir lower edges,which are also their front edges, rotating in either direction, passing near the floor or bottom of barrel 0,-remove and give an upward motion to any sediment or hard substance that may collect thereon. A little distance above the scrapers d is a pair of paddles e, whose upper and lower edges are cut into notches f, and along their horizontal center line is a number of square holes g, (three in this instance.) This pair of paddles is set at such an angle that by the rotating of vertical shaft 0 the upward current caused by the scrapers 01 will be reversed, excepting what material may pass through the holes 9 and otherwise escape their action. Next above paddles e is a pair of paddles e similar to or may be identically the same in construction, but which are set on vertical shaft at an angle opposite, so as to reverse the current formed by paddles e, and by this arrangement of a sufficient number of paddles I am able to thoroughly agitate and mix the material desired.

Some distance above the upper or last pair of paddles the vertical shaft 0 is made square, so as to engage the gear h by passing through the square hole h in its center, as before described. The top of shaft 0 is round and fitted to a bearing or box r in bracket 2. Said bracket 'i'is provided with two bearings 19 19, connected bya rib q, and directly under bearings 10 p are lugs s s, which are bolted to corresponding lugs t t,which are a part of spider u. Through and fitted to the bearings 19 19 passes a shaft m, to the front or inner end of which is fastened a gear Z,which engages gear h, and upon its outer end is a crank or handle n, (in this instance,) but to which may be fastened any device for the purpose of conducting or transmitting power thereto.

The spider a has a central hub to, having a hole passing vertically through it, forming a bearing for the hub on lower side of gear h, and having three horizontalarms spaced equidistant passing to and a little beyond the edge of barrel or tank to which it is intended to be fastened. Said arms are turned down a sufficient distance to admit of passing a set-screw j through them near their points for the purpose of fastening them securely to barrel. One of these arms 1: is adjustable in regard to length by means of the thumb-screw lawhich passes through the arm n and engages with a nut 20 in slot 00 in lower arm 1;.

The step a is fastened to lower end of vertical shaft 0 by a washer a being riveted to shaft, as shown in Fig. 5, so that the machine may be applied to a barrel of mixed paint by first putting vertical shaft 0, with step a attached, into barrel and by blows on top of shaft seating or driving points b into bottom,

then placing spider u, with its attachments, in position on top of barrel, and turning up set-screws j.

I am aware that prior to my invention paint and liquid agitating or mixing machines have been made, and therefore do not claim such a machine, broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is

The combination, in a paint-mixing ma- I0 chine, of a vertical shaft 0, journaied at top and bottom ends and carrying at lower end two double-edged concave scrapers (I, as described, and for purposes set forth.
