To (1J/l. 'wh/mn it 'mf/Ly concern:

Beit known that we, Tnnoponn A. SwimTH soN and GEORGE E. Borna, citizens of the United States, residing at Whittemore, in the county of Kossuth and State of iowa, have invented certain new and useful lmprovements in Mixing-Machines, of which the following is a specification.

This invention relates to improvements in intermingle the materials rapidly and thor ou ghly.

Another object of the invention is to provide-means for the discharge of the materials after bein mixed.

Other o jects and advantages of the invenf tion will be disclosed in the subjoined description'and explanation.

ln order to enable others skilled in the art to which our invention pertains to make and use the same, we will now proceed to describe it, referring to the accompanying drawings, in which- Figure 1 is a view in side elevation of a mixing-machine embodying our invention, showing by dotted lines one of the positions which the feeding or supplying hopper may occupy. Fig. 2 is a plan sectional view taken on line 2 of Fig. 1 looking in the direc tion indicated by the arrow. Fig. 3 is an end view in elevation thereof, showing a portion of the support for'the hopper. Fig, 4 is a fragmental side or edge view of the rotary o. im, showing the hopper located in position to discharge the materials from the drum. Fig. 5 is an end View of a portion of the rotary drum, showing the hopper in the position illustrated in Fig. 4 and illustrating a portion of the support for the hopper; and

ig. 6 is a detached perspective view of the supporting-bracket'for the hop por.

Like numerals of referenc refer to corresponding parts throughout. the different views ofthe drawings.

The reference-numeral 10 designates the main or supporting frame, which may be made of any suitable size, forni, and mat. rial, but preferal'ily rectangular in shape, shown Transv-rseiy ournaled on the lower of the rame 1G near its corners are and 12, on each ci' which is moui a fric tion-roller i3, which are prefer-abi provided at each of their ends with peripheral. liange ortion Vhalts 11 'le for the purpose to be presently c pla-ined. lli'ounted on one of the shaft 'l2isapinion 15, which meshes with a gear 16., mounted on the adjacent end of a shaft/.17, wl'iich is transversely journalcd on the niain or supporti franie at a suitable distance above the shatj` 12 and which may have on each of its'ends a crank-handle 18 for turning same. @n the opposite end of the shaft 12 from that which the pinion is mounted is a pulley 1Q, to whiclii power may be applied by means of a belt for imparting rotary iotion to shaft. Extending horizontally from one end of the frame 10 tc its other end and located at a suitable distance above the rollers i3 at each side of the fran'ie beains 20, 'which' comprise a part of 'the supporting-frame andy afford support for the shaft 1'?, which, as before stated, is transversely and. horizon-v tally journaled on the inain frame. livotally secured at one of its ends to each of the beams 20 nea.r;,the shaft 17 thereon is a', bar 21, which bars extend in parallelism with the beams 20, and each has in its end oppositev the pivoted end an opening 22 to receive a pin or bolt to be used for adj ustably securing said bars to the lupriglits of the main frame, which uprights are provided with a series of'- openings 2li, located above one another, as shown in Fig. 1 of the drawings. Transversely journaled on the bars 21 at suitable distances apart are series of shafts 25, on each of which is mounted a .roller 26, employed to support and drive an endless conveyer 27, which may be of the ordinary or any preferred construction. Each of the rollers 26 may be provided at each of its ends with sprocket-wheels 2t:L to engage sprocket chains 27a, located at each edge of the conveyer. @n one end of one of the shafts 25, adjacent to the shaft'l?, is mounted agear 2S, which meshes with a pinion 29 on that end of the shaft 17 opposite the end thereof on which the gear 16 is mounted. Located within the main frame and between the sides and beams 20 thereof is an open-- ended drum 30, which is mounted in frictional' Contact with the rollers 13, so as to be rotated-Titi ro XOO , inserting the thereby. Asbefore stated, each of the rollers 13 is provided at each of its ends with a peripheral flange 14 to prevent the endwise displacement of the drum-- The inner surface of the drum is provided with a series of curved cleats or ribs 31, which extend inwardly a slight distance and are employed for the purpose of holding the materials so as to'prevent the saine sliding toward the bottom of the drum. In other words, said ribs are curved toward the middle of the drum in the direction opposite to its movement in order that the materials may be caught and retained by the ribs as they fall from the conveyer and be carried upwardly to a distance sufficiently high to cause them to be again deposited on the conveyer.

A feeding-hopper 32, which has an inclined chute 33 leading into the drum, may be mounted by any suitable means at one side o`f the main frame; but in the present instance I have shown it as being mounted 'on a movable stand or support, consisting of four

posts

37, 38, 39, and 40, which are connected together at suitable distances apart by means of brace-bars 41, so as to form a rectangular support or frame. Each of said posts is provided at its lower end with a roller or caster 42 to enable the support to be moved from one point to another. The

posts

37 and 38 or those adjacent to the drum are provided with a series of lateral openings 43 to receive pins 44, used for adjustably securing the bracket upon which the hopper rests and is secured. This bracket consists of two members 45, which aresecured to the sides of the hopper at its rear portion by means of bolts, and each of said members has in its rear portion an opening 46, through which the pins 44 are passed. Extendin downwardly and forwardly from each of the members 45 is an arm 47, which are slightly inwardly inclined, as shown in F i f. 1, and united by a cross-piece 48 and which will rest at their front portions against the bottom of the hopper and at their rear portions against the front posts of the supportingframe therefor, thus firmly bracing the hopper. This hopper may be located in the position shown in Figs. 1 and 3 of the drawings, so as to supply the materials to the conveyer 27, or it may be located so as to supply the materials to the lower portion of the drum or beneath the conveyer by removing the pins 44 and lowering the hopper to the desired position on its supporting-frame, when it may again be secured in position by pins through the openings 46 into those, 43, in the front posts. After the materials have been thoroughly mixed they maybe discharged from the machine by moving the hopper 32 to within the drum near its upper front portion, as shown in Figs. 4 and 5 of the drawings, when it will receive the materials as they are dropped from the drum, as indicated bythe arrows in Fig. 4, from whence they will be discharged through. the chute 33 to one side of the machine.'

From the foregoing and by reference to the drawings it will be readily understood and clearly seen that the drum surrounds the conveyer, but will in no wise interfere with the operation thereof, since the bars 21, which support the rollers on which the conveyer is mounted, are located at a distance from the open ends of the drum. It is further apparent that as the bars 21 are pivotally secured at one of their ends they may be elevated at their other efnds, so as to give the desired inclination to the conveyer, which adjust ment may be performed by removing the pins or bolts from the openings 22 in the bars, after which the same may be raised to the desired point and there held by inserting the pins or bolts through the openings 22 in the bars and into the openings 24 of the uprights of the main frame.

Located on the upper portion of the main frame is a tank or receptacle 34 for water which may be discharged through a pi e 35 and a spraying device 36 on the end o said pipe, so as to fall on the materials within the machine.

The operation is simple and as follows: By applying power to the shaft 17, which may e done by means of the crank-handles 18 or otherwise, it is obvious that the gear 16 on said shaft, meshing with the pinion 15 on the shaft 12, will cause the same and its roller 13 to rotate in the direction indicated by the arrow on said roller, which operation will cause the drum 30 to be rotated in the direction indicated by the arrow thereon. As the shaft 17 is geared to one of the shafts 25, which support and drive the conveyer, it is evident that in the rotation of the shaft 17 and of the drum the conveyer will be caused to travel in the direction indicated by the causing the materials as they .through the hopper 32 and chute 33 to the conveyer to be deposited within the rotating drum, which by reason of the pockets or receptacles formed by the curved ribs 31 will carry the materials upwardly until by reason IOO arrow, 'thus are supplied`r IIO of their gravity they will fall from said pockv ets onto the conveyer, from which it will again be deposited within the rotating drum, thus causing a thorough and rapid intermingling of the materials.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-
