Specification of Letters Patent.

Application filed March 31, 1918. Serial No. 757,931.
' To all whom it may concern:
Beit known that I, EDWARD W. BRACK- ENBURY, a subject of the Kingl of England, residing at Milwaukee, in the county of Milwaukee and State'of Wisconsin, have invented a new and useful 'Mounting for Drums of Concrete-Mixers, of which the following is a specification.
My invention relates to improvements in the mounting of drums for concrete mixers of the type in which the drum is tilted to discharge; and the objects of my improvement are to simplify the construction, and thoroughly protect the bearings and driving gear from the access of extraneous matter thereto, having careful regard to the convenience of assembling, the durability, eicient operation and all mechanical considerations involved. I attain these objects by the means illustrated in the accompanyin drawing in whichigure 1 1s a view of the machine loolnng sidewise of the supporting trunnions of the drum. Fig. 2 is a view of the machine looking endwise of the trunnions. Fig. 3 is a fragmentary cross section on the line 1-1 of Fig. 1 and Fig. 4 isa fragmentary cross section on the line 2-2 of Fig. 1.
The machine illustrated is a batch mixer of the tilting type in which the drum 10 is continually rotated on its axis at all times while `the machine is in use and is tilted on the axis of the trunnions 11 whenever the drum is to be discharged. As the form of this drum and its mode yof o eration form resent invention they need not be further escribed here.
The drum is primarily mounted in, or sup orted by, an integral ring 12 which has, pre erably formed integral therewith the trunnions 11, and these latter are carried by the usual -pedestals 13. The drum 10 is surrounded by a ring 14 which has ,formed integral-therewith the gear 15. The ring 14 is secured to the drum at substantially the middle of its length and around its center of gravity. The exterior of this ring is machined to form a cylindrical bearing for the drum, and the projecting web or flange of the gear 15 is machined on its sides to form a bearing positioning the drum sidewise in its supporting housing ring 12. An annular plate 16 is attached to ring 12 by bolts 17, holding the ldrum. from slipping out of the housing ring 12. The rings 12 and 16 are machined to fit the bearing surfaces of the ring 14 and flange of the gear 15. At the point of attachment of the trunnions 11 to housing ring 12, the interior space in ring 12 is enlarged sufficiently to contain whatever gearing is necessary. In the example shown, 15 is a bevel gear engaged by the bevel lpinion 18 on the shaft 19 extendmg throu h the hollow trunnion 11. Gearing vof this type however is .not essential in this device. 15 may be formed as a spur gear driven by a spur pinion on a short cross shaft mounted in the housing 12, which cross shaft would also carry a bevel gear engaged by the bevel pinion 18 as shown in Patent 690,783, Fig. 5.
A frame 20 attached to the housing rings 12 and 16 supports the feed spout 21 and other auxiliary devices which are intended to tilt with the drum but not to revolve may be similarly attached.
The drum is tilted by means of a lever 22 attached to one of the trunnions and operated by a hand lever 23 and link 24 or other convenient means for tilting may be employed.
While the machine is in operation, the gears and bearings are completely covered and protected from dust and dirt which is very prevalent inthe vicinity of a concrete mixer. to support the weight and the drum mounting is of the strongest and simplest form.l The drummay be readily removed from the machine for shipping and for repairs and is as readily replaced. v
The machine herein shown is by way of example only and many changes in details may of course be made without departing from the spirit of the invention as set forth in the claims. A
Having now fully described my invention what I claim is: f
1. In a mixin machine, an element adapted to be rotate a supporting guiding and rotating means for the rotating element consisting of a single ring attached to or formin part of the lrotary element, said ring being located substantially around the center of gravity of said rotary element with both ends of ,saidv rotary element accessibly protruding from said ring, cylindrical and flange bearing surfaces and gear teeth on said ring, a supporting ring mounted on the machine frame, cylindrical and The bearings are adequate in size flange bearing surfaces on said supporting ring fitting and entirely covering the corre-f spondin surfaces on `the rotary element ring, said cylindrical bearing surfaces adapted to support the Weight of said rotary element and said iiange bearing surfaces adapt-A ed to locate the rotary element in the supporting ring endwise of the axis of rotation of the rotary element, said supporting ring entirely inclosing the gear teeth and a driving gear contained Within said supporting ring adapted to rotate said rotary element.
2. In a miXin machine, a rotatable element, a supporting, guiding and rotating means for said rotatable element consisting of a single ring attached to or forming part of the rotatable element, said ring being located substantially around, the center of gravity of said rotatable element with both tained supporting ring fitting and entirely covf ering the corresponding surfaces on the rotatable element ring, said supporting ring entirely inclosing said gear teeth, a driving shaft extending through one of said trunnions and a. driving gear on said shaft con- Within said vsupporting' ring adapted to rotate said rotatable element.
