Application lod VOctober 22, 1.906!l Serial No. 840,077 i To all whom it mayvconcem: Be it known that I, TERRY Bmx'r, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, 4have invented I bination and arrangement 0f parts, `as will behereinafter described and claimed,

` One obj ect of my invention is to provide a machine of this character which will bey of simple and durable construction, and by means of which the mixing may be effectively and expeditiously performed.

A further object of my invention is to effect improvements in the Ameans for feeding and discharging the material into and from the mixing receptacle or container. v

The above and other objects, whiclwill appear as the nature of my invention is more fully understood, are accomplished by the'construction illustrated in the accompanying drawings1 in which,-

Figure 1 is-a top plan view-of a mixing machine embodying my improvements; Fig. 2 is a side elevation of the same;` Fig. 3 is an end elevation; Fig. 4 is a verl tical longitudinal sectional view, taken on the linel 4-4 of 'F-ig. 1; Fig. 5 is a vertical transverse sectional .view; and Fig.` 6 is a detail vertical transverse sectional view, taken on the line 6 6 ofFig. l and showing the swinging mixer-carrying frame in full lines in-its normal position, and in dotted lin`es in its tilted position.

Referring to the drawings by numeral, 1 denotes ya frame or support, preferably consisting of two enduprights 2 and 3 connected by a longitudinal bar or beam 4. Each of said uprights is formed with supporting feet 5 upon which wheels or rollers may be mounted, if desired, to permit the frame to be readily triansported.V The connection between the bar 4 and the uprights 2 and 3 is preferably'detachable, and, as shown, consists in forming the ends of the bar 4 with reduced portions 6 which project through openings formed in the, uprights 2 and 3 and are retained therein by wedgeshaped keys 8. Said keys paw through openings v formed in said reduced ends of the bar4 and are preferfrom being lost.

Upon theupper ends of. the uprights 2 and 3 are formed semi-circular bearings `10 in which are removoscillating or tilting frame 1 2 which carries a mixing 'receptacle or container 13. Said frame 12'is preferably constructed of two half-sections 14,V 15, which are hereshownin theform of fmetalcastings. Each of said half-sections comprises a body portion 16 having at one of its ends one of the trunnions 11, and at its opposite end a transversely extending semi-cylindrical casing section 17 which is formed along its 4side edges upon the two casing sections 17 are secured together by bolts or other suitable fastening means 19, said sections 17 forming a substantially cylindrical shaped casing,its ends,which are open, being somewhat tapered,

`as shown. The mixing receptacle or container 13, which is in the form of a hollow cylindrically shaped shell formed with taperedfends 20, 21, -is mounted to rotate within the transversely disposed casing 17, ball bearings 22 being provided between the outer surface of said receptacle and the inner surface ofthe casing 17 `to permit the former to rotate with a minimum amount of friction. The ball bearings are retained within the casing by annular plates 23 and are adapted to be inserted into the same through the openings 24 formed in said casing and closed by caps 25, said openings also serving to permit an oil or lubricant to be distributed upon the bearing balls 22. The interior of the mixing receptacle 13 is formed with spiral-ly arranged rows of inwardly projecting and angularly disposed wings or blades 26 which serve to thoroughly agitate or mix the material within the receptacle when the latter is rotated, as will be presently described. The material to be mixed is introduced through the tapered end 20 of said receptacle by means of a tapered trough 27 which is preferably mounted upon the adjacent end of th'e .casing 17 by means of braces-28. The opposite end 21 of the mixing receptacle the latter.

llt will be seen upon reference toFigs. 1 and6 of the 13 serves as a discharge for drawings, thatthe ,trunnion's' 1 11are disposed eccen-` -being of greater size and "weight than the corresponding portion of the other section 14. Owing to this construction, it will be seen that when said frame is hung upon the uprights'2, 3, its overbalanced side or portion 'with angular'ly projecting flanges 18. Said flanges 18 will swing downwardly and, since the discharge end ings, I preferably employ alever 30l which is pivo'ted.

intermediate its ends at 3l upon the inner side of the assist in supporting the swinging or tilting frame 12,

the flanges 18 upon'the underside of the casing 17 are curved or arc-shaped, as shown at 37, and are adapted to engage a supporting friction roller 38 which is journaled in a block or bearing 39 secured centrally upon the bar 4 of the frame 1.

In order to rotate the mixingreceptacle 13, I preferably journal, in the enlarged or overbalanced portion of the frame l2, a shaft 40 4,which has secured upon its inner end a pinion 41 disposed in a recessed portion 42 of said frame. Said pinion meshes with a toothed gear 43 which is secured upon the outer side 4of the receptacle 13 and rotates in a recessed portion 44 of the casing '17, as shown. which `projects beyond the upright 3, has secured upon it a fly Wheel 45 which is provid ed with a crank han-y dle 46, by means of which, said wheel, and. hence said shaft, may berotated. If desired, the shaft 40 may be driven by power by placing tight and loose pulleys upon the same, as will be readily understood. In the frame 12 is provided a covered lubricating opening 47, through which oil or other lubricants may be supplied to the shalft 40.

The use, operation and advantages of my invention vwill be readily understood upon reference to -the diawings. lt will be seen that when the receptacle 13 is in its normal position, that is, in a horizontal plane, the material to be mixed may be introduced into the same through its inlet end 20, and that when the handle'46 is rotated, said receptacle will, through the gears 41, 43 upon the shaft 40, be rotated to thoroughly mix The outer end of the shaft 40, 4

its contents. When it is desired to discharge said contents, the dog 35 is disengaged from the lever 30 and thelong arm of the latteris elevated, to permit the swinging frame 12 to tilt to the position shown in dotted lines in Fig. 6v oi the drawings. In'this position, the receptacle 13 will b'e inclined downwardly with its discharge end 21 lowermost, so 'that the contents oi said receptacle may pass out oi the same.

While I have shown and'described the preferred embodiment of my invention, it will be -understood that I do not wish to be limited to the precise construction herein set forth, since various changes in the form, proportion and the minor details of construction may he resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what l claim as new and desire to secure by Letters-Patent is:

1. In a mixing machine, the combination of a main frame, a tilting frame pivotally mounted therein on one side of the center of weight thereof, a receptacle carried tilting frame on the weightier end thereof, and means con? nected to the main frame to lock said lever in an adjusted position.

2. A mixing machine comprising a frame having journal hearings and an intermediate supporting fric-tion roller, a tilting frame having trunnions to turn in said bearings and a curved rib to engage said supporting roller, a transversely disposed hollow mixing receptacle mounted to rotate in said tilting frame and having inlet and outlet openings at its opposite ends and'angularly disposed internal agitating wings, a gear wheel upon said receptacle, a shaftyin said tilting frame, a pinion upon said shaft, in mesh with said gear, means for rotating said shaft, and means for supportingthe overhalanced portion of said tilting frame, substantially 'as described and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of'two subscribing witnesses. l

TERRY BLIXT.
