MORTAR OR CONCRETE MIXER.
trac ea I Specification of Letters Patent. Patgyflged N 3155 jjficillfifi,
Application filed January 8, 1909. Serial No. 471,265.
My invention relates to machines for mixing mortar concrete, etc. and has for its objects the provision of a machine provided with means for regulating the relative proportions of the sand and cement delivered to the mixing, device. the provision of a mixing drum in which the sand and cement are first thoroughly mixed in their dry state, and
another mixing drum in which the sand and vcement are mixed with water, the latter drum being adjustably mounted so that the consistency of the concrete may be regulated by causing the mixture to pass through the drunr where mixed with water rapidlyv or slowly. The entire machinevismounted on a wheeled truck apd the machine and truck are actuated by a motor mounted on the truck.
My invention will be described in detail hereinafter and illustrated in the accompanying drawings in which Figure 1 is a view in elevation of the front oi? the machine, Fig. 2, a View of the side of the machine on which is mounted the sand and cement feeding apparatus. Fig. 3, a view of the opposite or delivery side of the machine some of the parts bein gomitted, and Fig. a vertical, longitudinal sectional View ot-the two mixing drums some ofthe parts being omitted.
in the drawings similar reference charpacters-indicate corresponding parts in all of the views. 7 v

51 indicates a hose connection tapped into pipe is to liush the interior of drum 25 to clean it of concrete, when closing down at the end of the day or other period, to pre vent it from hardening in the drum.
Having thus d ascribed my invention what I claim is- 1. In a mortar or concrete mixer, a nonrotetable drum having one end pivotally supported, segmental racks suitably secured, a shuft journeled on said drum, pinions secured to said shaft and meshing with said racks, and means to rotate said. shaft-to adthe inclination of said drum.
3. In :1 mortar or concrete mixer, a nonroletsble drum having one end pivotally supported, segmental racks suitably secured, a shaft journnlcd on said drum, pinions secured to said shaft and meshing with said segmental racks, e worm wheel secured to the shaft, a casing inclosing said wheel, and a worm. shaft journaled in said casing and meshing with said Worm wheel, said casing being held from rotation on the Worm wheel.
3. A mortar or concrete mixer comprising a rotatable drum, endless belt conveyors for the dry ingredients of the mortar or concrete emptying into said drum, means to vary the relative speed of the belt conveyors to regulate the relative quantities of the dry ingredients, a non-rotatable drum positioned to receive the contents of said rotatable drum and pivotelly secured at the receiving end, segmental racks suitably secured, a shaft journaled on said drum, inions secured to said shaft and meshing with said racks, and means to rotate said shaft to adjust the inc'lination of said drum.
4. A mortar or concrete mixer comprising a rotatable drum having spiral projections on its interior, endless belt conveyers for the dry ingredients of the mortar or concrete emptying into said drum, the driving shafts of said conveyors having oppositely arranged cone Hulleys'secured thereto, a belt geared to sai pulleys, a cap loosely mounted on the delivery end of said rotatable drum and having a spout connected therewith, a non-rotatable drum at the delivery end of said spout, a shaft journcled in said non-rotataole drum and having stirring blades secured thereto, said non-rotatable drum pivotally secured at the delivery end of the spout, a shaft journaled on said non-rotatable drum, segmental racks suitably secured, pinions secured to said shaft and meshing with said segmental racks, a Worm -wlieel secured to the shaft, a casin inclosing said worm Wheel, a worm shaft journaled in said casing and meshing with said. worm wheel, and a water pi for supplying water to said non-rotetnb e drum.
in testimony whereof I hereto aflix my signature in the presence of two witnesses.
