MIXING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 560,259, dated May 19, 1896.

Application filed January 14,1890. Serial No. 336,860. (No model.)

To all whom, t may concern.-

Be it known that we, JOHN Il. DAY and CHARLES KRUMHoLZ, citizens of the United States, and residents of the cityof Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Mixing-Machines, of which the following is a specification.

The various features of our invention and the several advantages resulting from their use, conjointly or otherwise, will be apparent.

from the following description and claims.A

In the accompanying drawings, making a. part of the specification, Figure I is a side elevation of a mixing-machine embodying our invention, a part of theadjacent side being broken away near the center to disclose the rotating device which operates in mixing. Fig. 2 is a vertical cross-section taken in the plane of the dotted line 2 2 of Fig. l, and looking from right to left.

A indicates the casing or box constituting the vessel in which the operation of mixing is conducted. The lower portion of this vessel is interiorly in cross-section of a semicircular form, while the upper portion has preferably V straight sides.

B is the top of the vessel.

One or more openings into the mixing Vessel for the admission therein of the articles to be mixed are present. Such an opening is Openings are also present for reaching the interior of the machine, and yfor cleansing the latter when it is desired to use the machine for mixing articles different from those previously mixed therein. These openings are preferably in the uppermost part of the vessel, and two of such inlet-openings are here shown in the top B, each opening being closed by a lid C, hinged to a stationary portion of the top. In Fig. l the dotted lines on the right hand `at the top of the mixing vessel show one of thes lids C when partly lifted.

rlhe interior of the mixer is occupied by a rotatable mech anism for carrying on the operation of mixing the material which has been introduced into the casing. A valuable kind of such mechanism consists of the devices herein shown, and which are as follows: A rotary shaft I extends horizont-ally within the casing A, and in a direction substantially parallel to the longitudinal axis of said casing. Radial arms J project at intervals from said shaft I. To these arms are attached strips or blades of suitable material. Each of these blades describes a spiraL-and the axis of each spiral is coincident with the longitudinal axis of the shaft I. The convolutions of t-he exterior spirals J J 2 (there are preferably two of these) run in the same direction while the convolutions of the inner'spiral J 3 run in a direction the opposite of that in which said spirals J and J 2 run. The effect of this arrangement of spirals is to carry the material the entire length ofthe casing, and while a part of the material is being carried in one direction by spirals J and J 2 another portion is being carried in the opposite direction by the spiral J 3, and in this way the whole contents of the casing are rapidly and intimately mixed.

The sha-ftl is suitably supported in journalbearings. In the mixers we have heretofore made the material therein to be mixed has entered these journal bearings and thus caused friction between the shaft and said bearings and has caused the shaft to bind. In this Way the shaft would, at the bearings, be more rapidly worn down and sooner be rendered unfit for use. Furthermore, the speed of revolution of the shaft was retarded. Thus valuable vpower was wasted and the character of the product of the machine was injured. To obviate these undesirable results, we have provided devices constructed and arranged as follows, viz: At each end of the casing A, where the shaft passes through the latter, is a bearing H, secured to the casing preferably by an annular flange H', extending out from the bearing and bolted to the adjacent portion of the casing. That inner portion of the periphery of the bearing which is inside of the casing is provided with a screw-thread. Upon this end of the bearing His screwed a cap H2. Through a closeiitting opening in the inner end of this vcap passes the shaft I. The space between the cap and the inner end of the bearing is filled with a suitable packing. The cap is then screwed forward on this ,bearing H, and the packing is thereby compacted and pressed upon the shaft I, thoroughly preventing the IOC egress of any portion of the material being mixed in the mixer. Such a construction of bearing and cap with packing is present around the shaft I at each end of the casing and renders the easing dust-tight at these bearings.

Another feat ure of construction which We have devised is as follows: The upper half R of each end of the casing-viz., all that part above shaft I-is made removable. This end plate or head R is preferably united to the remainder of the casing by L- flanged pieces S. One of these pieces is secured to the out-` side of the head R,at the bottom edge of the latter, and te the outer face of each side edge of this head another of these pieces S is secured. These pieces S are bolted to iian ges S', formed on or secured to the inner faces of `the sides of the easing at its end, and also te the outwardly-extending flange S of the upper edge of .the lower half of the end of the casing. This construction enables the upper half or head R to be readily unbolted and lifted away from the easing and from the flanges of the bearing II, carrying with it the L-flanges S attached to it.

The bearings II can be readily unbolted from their adjacent lower halves of the ends ofthe easin g, and the shaft I with said bearings is readilylifted out for repair whenlnecessary.

The shaft I is prevented from slipping longitudinally in its bearings by suitable checks. In the present instance `these checks consist as follows, viz: A collar G is fixed to the shaft outside of the bearing II, at the right- `hand end ofthe easing, and the hub of the gear-wheel F is present outside of the bearing at `the other end of the casing. The shaft is rotated by mechanism of `any suitable de seription. In the` present instance it is rotated by the wellknown gear, consisting of toothed wheel F on the shaft I and pinion F on sha-ft F2. rlhis lattershaft also carries the loose pulley F4 and tight pulley F3, whereby-power is communicated to said shaft F2. Shaft Ft) is supported in je urnal-bearin gs, the latterin the present instance being located as follows, viz: the one bearing in leg er frame E, supporting the adjacent end of casingA, and the other in the leg E.

Fi is a collar fixed on the 'shaft F-to pre vent the latter from slipping toward leg E and through `the journal of the latter.

` The various features of our invention are effective in operation. Vhile they are all preferably employed together, one or more of Athem may be used Without the remainder, and, in so far as applicable, one or more of said features may be used in mixinganachines other than the one herein specifically set forth.

What We claim as new and of our invention, and desire to secure by Letters Patent, is-

l. In a mixing-machine, a reel embodying a horizontal shaft provided with concentric spiral blades of opposite eonvelutions and a casing through the sides of which passes the said shaft, the bearings of the shaft at said sides being provided with stuffing-boxes, the caps of which are arranged to screw on or olf in the inside of the mixer, thus preventing the material that is in the mixer from, getting inte the said bearings, substantially as specified.

2. In a inixinganaehine, the casing containing the shaft carrying the spiral blades, the bearings of the shafts being provided `with annular flanges bolted to the end of the casing, and extending within :the casing and there carryinga screw-thread and the screwcap located on the shaft within the casing and engaging the screw-thread of said bearings, substantially as and for the purposes specified.

In a mixing-machine, a reel embodying a horizontal shaft provided with concentric spiral blades of opposite cenvolutions, and a casing having dischargechutes located in the upper portion of the circular bottom of the easing on the bottom.

4. In a mixing-machine, the casing containing the horizontal shaft having concentric spiral blades of opposite eonvolutions, and the casing being provided with removable ends above the shaft, these ends having Lm flanged pieces S secured thereto, the lower half of each end having at its upper edge the iiange S', for juncture with one of said L- iianged pieces, substantially as and for the purposes specified.

5. In a mixing-machine, the reel having a horizontal shaft carrying concentric spiral blades of opposite convolutions, and having at the inside of the casin g stuffing-boxes, the ends of the easing above said shaft being provided with L ;-tlanged pieces whereby the said ends are removably secured to the casing, and the upper portion of the easing being provided with the door C and dischargechutes, substantially as and for the purposes specified.
