JOHN FISH, OF SOUTH, BEND, INDIANA.
CON CBE TIE-MIXER.
Specification of Letters Patent.
Patented June 30, 1908.
Application filed June 29, 1907. Serial No. 381,542.
To all whom it may concern:
Be it known that I, JOHN FrsH, a citizenof the United States, residing at South Bend,
in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Concrete-Mixers, of which the following is a s ecification.
This invention re ates to concrete mixers.
One object of the invention is to rovide a concrete mixer embodyingv such 0 aracteristics that it will automatically measure and deliver the materials mixed in their proper proportions to the mixing chamber.
Another object resides in the provision of a concrete mixer so constructed and arranged that the mixingcylinder may be adjusted to different inclinations in its longitudinal direction to control the speed or gravity of the concrete mixture in 1ts discharge from the cylinder.
A still further object of the invention is to provide a continuous concrete mixer whose parts are so associated in their cooperative relations thatpositiveness and effectual operation results both in the mixing of the mate rials together and in the discharge of the mixed materials from the machine.
With the above and other objects in view the .present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated ,in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details, without departing from the s irit or sacrificing any of the advantages 0 z the invention.
n the drawings ;Figure 1 is a side elevation of the invention. Fig. 2 is a view illustrating the invention partly in plan and partly in horizontal section. Fig.3 is a vertical sectional view on the line a; as of Fig. 1. Fig. 4 is a vertical sectional view on the line y y of Fig. 1. Fig. 5 is a sectional view of the hopper including the measuring roller "and chute. Fig. 6 is a fragmentary view of one end of the combined feeding and measuring roller illustrating the filling of one or more of the o'ckets thereof to regulate the measuring oft e materials in different pro ortions.
To ermit of the adjustment of the mixing cylin er 9 to different inclined positions in its longitudinal direction, is the reason why the drive shaft is formed of the two arts 6 and 7. If the frame 4 at the inner on machine remains fixed while frame 4 at the outer end of the machine is adjusted vertically, the spaced bearings 11 of the bracket of the such adjustment of the mixing cylinder un less the drive shaft was formed in twoparts. For this reason there is fixedly secured to the inner end of the part 6 of the drive shaft a disk 13 which carries lateral projections 14 which project through the slots 15 of a disk 16 carried at the inner end of the part 7 of the drive shaft. These slots 15 of the disk 16 permit of sufficient lay of the lateral projections 14 as to provide for a universal coupling between the parts 6 and 7 of the drive shaft, so that the mixing cylinder may be driven at varying angles to the drive shaft. Thus it will be understood that the part 6 of the drive shaft of the mixing cylinder is journaled at both ends in bearings which are pivguide ways 4 is a hopper 18 provided with a measuring roller 19 adapted to regulate the quantity of material passing through the hopper, the materials in their passage through the hopper being controlled by the.
measuring roller 19, and when so'controlled are discharged into the chute 20, as shown in Fig. 2, the chute being preferably curved and narrower at its discharge end than at its inner end.
The chute is preferably open at its top so that waterfrom the water tank 21 supported by brackets 22 of the machine may be lead into the chute to moisten the materials by means of the nozzle 23 which has connection with the tank 21 through the valve pipe 24. By reason of the valve pipe 24 thewater may be supplied in the proper proportions.
The measuring roller 19 is mounted upon a shaft 25 which has a sprocket 26, whereby,
- portioned so that the feeding of onematerial through the instrumentality of a chain 27 leading from the sprocket 28 of the art 7 of the drive shaft, the combined feeding and measuring'roller may be operated by and with the drive shaft.
In the compounding of concrete compositions, the materials must be properly prober of pockets upon the o posite end thereof,
the pockets at one end 0 the roller being arranged for cooperation with the compartment 29 of the hopper and the pockets at the opposite end of the roller being arranged for coo eration with the other compartment 30 of t e hopper. This arrangement of a greater number of pockets at one end of the roller than at the other end thereof is to permit of the feeding of one ingredient with relation to the other, as for instance cement and sand, so that the former may be in proportion with the latter and produce the required ratio as for instance one to nine or one to two, or one to one, as'may be required. This regulation of the quantity of one material with relation to another, may be accomplished by providing the measuring rollers with the required sizes andnumbers of pockets, or by placing a block 33 in one or more of the ockets at either end of the measuring r01 er, as shown in Fig. 6 to cut out any required number of pockets. In Figs. 3 and 4 of'the drawings, the pockets for the cement or other material are three in number and for the sand or other material nine in number, so that in one revolution of said guide ways, a shaft in two parts with cylinder carried the combined feeding and measuring roller, one part of cement to three parts of sand will be delivered to the chute 20, and by means of the water tank and its connections the materials thus mixed may be dampened accorde ing to conditions or requirements. g
After the mixture is delivered to the IIliX- ing cylinder it is rapidly carried 11 ward by' the blades 34, (see Fig. 2) and fa ls on the bottom of the cylinder as it reaches the top of the latter and then slowly gravitates to the discharge end of the cylinder.
From the foregoing it will be seen that there is provided in this invention a continuous mixer, as the material is beingcontinw ously fed in\ proper proportions and discharged into the mixing cylinder, and without any attention from the operator except to see that the hopper is kept supplied with material to be mixed. a
What is claimed is I 1.
