the ojbectof the invention being to provide a simple, compact and practical machine for mixing sand and cement in the manufacture of concrete, the machine being adapted to mix'the ingredients in the proper proportions and discharge the same from the machine after the mixing operation has been completed. 3
With the above general ob lect in view, the
- nature of which will more fully appear as the ment of parts as herein fully description proceeds, the invention consists 1n the construction, combinatlon and arrange- (lescribed, illustrated and claimed.
In the accompanying drawings :Figure 1 is a, plan view of a concrete mixing machine embodying the present invention. Fig. 2 is an end View thereof. Fig. 3 is a vertical cross section taken in line with the compartment hopper.
The concrete mixer contemplated in this invention comprises a suitable supporting frame 1 of any preferred construction which forms a support for a semi-cylindrical trough 2 in which'the mixing operation takes place. Extending-lengthwise within said trough is the main shaft 3 provided with rotating spokes 4 to which are keyed a corresponding number of mixing blades, shovels or boaters 5, the main body portions of which are fiat or straight as shown in Fig. 3 while the outer portions thereof are curved forward in the directionof rotation of the shaft as shown in said'figure and'further the adjacent. edges of the blades overlap each other as shown in Fig. 1. The arms 4 in addition to being radially arranged, are arranged in spiral series so thatv a general spiral arrangement is also imparted to the blades or shovels 5 as clearly indicated in Fig. 1, whereby said shovels in addition to Specification of Letters Patent. Application filial August 5, 1908.

chine which is formed by leaving the trough.
2 open at the discharge end of the machine.
Mounted upon the trough 2 and the supporting frame 1 thereof is a base 7 of a double or compartment hopper 8 comprising a relatively lar e sand compartment 9 to the relatively smal er' cement compartment 10. In the bottom of the sand compartment 10 is a spiral conveyer or auger 11 while in the bottom of the cement compartment there is a relatively smaller spiral conveyer or auger 12 These conveyers 11 and 12 advance the cement toward discharge 0 enings in the end wall of the hopper which ead directly into the trough occupied by the rotating shovels or blades 5. The shafts of the conveyers 11 and 12 are provided on their projecting ends with sprocket wheels 13 and 14 respectively over which runs a driving sprocket chain 15 which is actuated by a larger sprocket wheel 16 on thenzain shaft 3. ferent shafts are properly timed to nzix the ingredients in the proper proportions.
The shaft 3 may be driven either by hand or by any suitable motive power.
The compartments 9 and 10 of the double hopper are divided from each other by an inclined partition l7,fian ed at its op osite end as shown at 18 and rab eted or be ted to the opposite walls of the hopper.
