SPECIFICATION forming part of Letters Patent No. 443,654, dated December 30, 1890.
Application filed April 16, 1890. Serial Nc. 348,280. (No model.)
To all whom, it may concern..-
e it known that I, ELAH J. PowERs, of Wilmington, in the county of New Hanover and State of North Carolina, have invented certain new and useful Improvements in Mixing-Machines,of which the following is a specification, reference being had to the accompanying drawings.
rl"he objects of my improvements are, first, the rapid and perfect mixing of all substances, and, second,to facilitate the cleaning and recharging of the mill. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of the complete machine. Fig. 2 is a perspective view of the interior revolving mechanism, showing the shaft, hubs, and radial spokes carrying the mixing-shovels, as hereinafter described. Fig. 3 is a longitudinal section of shaft and hubs, showing the mode of attaching the spokes to hubs and the mixing-shovels to the spokes. Fig. 4 is a perspective view of one of the mixing-shovels detached from spokes. Fig. 5 is a perspective View of cleaning-knives, showing their mode of attachment to the hub and their relative position to the spokes, both of which are shown in cross-sections. Fig. 6 is a perspective'view of entire machine with a port-ion of the casing A broken away, showing the section and position of the dump-lever and trap. Fig. 7 is an enlarged perspective view of trap, stirrup, and lower portion of lever detached from case.
Similar-letters referto similar parts throughout the several views.
The cylindrical inclosing-case A, its legs o1" standards B, feed-hopper C, and trap D, covering the dump-opening E, constitute the frame and covering of the machine. The lever F is attached by means of a pin-joint O to the trap -blade I), and continuing thence downward is hinged in the base-plate I, which is iirmly secured to the flooring. rl`he trap-blade D lies in and slides through a stirrnp R, which is firmly secured to theunder side of the containing-case A and retains the trap-blade D in its position over the dump-opening E when so desired. Any means for sustaining the trap-blade may of course be employed.
On the cross-rails of the frame B are the bearings H, retaining the shaft G, to which v are attached the mixing-shovels L, as hereinafter stated. The shaft G, Fig. 2, has firmly keyed thereto two hubs I I, from which radiate any desired number of spokes J J, the spokes J J on both hubs I I being so arranged that they lie in parallel pairs.
To the' hub I, at the farther extremity of the spokes .I J, are fastened the mixing-shovels L L, held by means of the bolts M M. The hubs I I are also provided with cleaningknives K K, Figs. 2 and 3, which knives are so arranged by a twist near the hub that their fiat sides are at right angles to the ends of the cylindrical cover A, and the extreme end of the blade K from the hub I will just clear the sides of the cover A.
The mixing-blades L, Fig. 4f, are formed of oblong plates bent in the centers of their cross-line, so that their extreme edges are at a distance from each other of a little less than the interior depth of the cylindrical cover A.
To operate the machine I place the core, Fig. 2, consisting of t-he shaft G, hubs I I, spokes J J, cleaning-knives K K, and mixingshovels Ifwithin the cylindrical cover by allowing the shaft G to rest in the bearings H, one-half of the coverAbeing removable to facilitate this action. A suitable gearing and power being applied to the shaft G, the shaft is caused to rotate at any desired speed. The hopper C, communicating with the interior 0f the cylindrical cover A, is provided with a suitable cover, by removing which access is had to the mixing-shovels L L, on which the substance desired to be mixed is poured from above. :3y causing the shaft G to rotate at a suitable speed and precipitating the substance desired to be mixed on the shovels L L, attached to the spokes thereof, the material is alternately lifted in the hollow of the shov.- els L L and lprecipitated therefrom when they reach the perpendicular, or thereabout, which action is continued until the desired amount of mixing or blending is attained. By placing the cover D in position to cover the dumpopening Ein the lower side of the cover A any substance contained therein is prevented from escaping. This cover may be removed and readjusted at will by a lever F or other convenient arrangement.
B y drawing back IOC the lever F the trap l) is forced to slide back in its stirrup or groove R, leaving the dumpopening E clear. The traphlade l) being of Such length that; by working the lever l it is not entirely withdrawn from the groove or stirrup R, itfis obvious that by replacing the lever l? in its original position the opening will he covered or closed. ly workingl the lever l? the trap or door D is removed from the opening' E, and any Substance falling Jrhereon is allowed to fall to the Hoor below, thus duinpingl` the contents of the cylinder.
As some of the substances desired Vto be mixed may be of a resinous or sticky nature, which by adhesion to Jshe sides of the cylinder would impede its rapid and perfect work, lhe cleaning-knives I( K are provided, their the casing, substantially as slet forth.
ln testimony of all which I have hereunto Subscribed my name.
