UNITED STATES ROBERT c. s'runns, or DALLAS, TEXAS.
VIBRATING MACHINE.
Application filed June 2, 1922, Serial No. 565,421. Renewed February 11, 1925.
To all whom it may concern:
Be it known that I, ROBERT C. STUBBS, a citizen of the United States, residin at Dallas, in the county of Dallas and tate of Texas, have invented certain new and useful Improvements in Vibrating Machines, of which the following is a specification.
My invention relates to paving apparatus and more particularly to a vibrator for use with the transmitting apparatus shown in -the patent granted to me on July 5, 1921,
No. 1,383,581; and the object is to'provide obtained to a high degree of etn'clency by the improved apparatus hereinafter set forth. Other ob ects and advantages will be fully explained in the following description and the invention will be more particularly ointed out in the claims.
Re erence is had tothe accompanying I drawings which form a part ofthis application.
Fig. 1 is a front elevation of the improved vibrator. Fig. 2 is a side elevation of the same slightly in perspective. Fig. 3 is a perspective view of the rear of the machine.
ig. 4 is a perspective view of the frame for the vibrator. ig. 5 is a detail view illustrating the manner of attaching the motor to the frame. Fig. 6 is a side elevation ofone of the flywheels, illustrating the manner of increasing or decreasing the weight on one side of thefiy-wheel.
Similar characters of reference are used to indicate the same parts throughout tho several views. I
The improvedvibrator is provided with a motor 1 of approved type to be driven by liquid or gas fuel. The motor is provided with a tank 2 and a magneto 3 and spark lug 4 and all other equipments for a gaso ine motor. The motor drives 'a main shaft 5 and a fan 6 is driven from the shaft 5 by suitable gear wheels and a belt 7 Two flywheels 8 are made rigid withthe shaft 5.
The motor 1 is hung in a suitable frame by means of laterally projecting flanges or lips 9. The frame consists of two longitudinal side beams or members 10 with upright members 11 to which the flanges 9 are bolted rigidly. The members 10 are rigid with each other b reason of a cross-beam or web member 12 ormed preferably integral with the members 10. The frame of the motor is absolutely rigid with the hanger frame composed of the members 10, 11, and 12.
The object of the frame or hanger frame is to make provision for two sets of rollers. Shafts 13 are mounted on the frame members 10. Rollers 14 are mounted on and support the shafts 13. Rollers 14: are between the frame members 10 and rollers 15 are onthe same shafts outside of the members 10. The rollers 15 perform the same kind of functions performed by the rollers 14. The object of the plurality of rollers is to distribute the force of the vibrations to different stringers of the transmitting apparatus.
The gasoline motor will create vibrations which will pass through the hanger frame and the rollers 14 and 15. In order to intensify or increase the force of the vibrations, provision is made for making one side of each fly-wheel 8 heavier than the other. Weight plugs 16 are' inserted in the rims of the wheels 8. The wheels have been made lighter on one side by making the cavities in the rims for the weights 16. But the weight is substantially supplied by the screw or weight plugs. There is a plurality of weights in each wheel. The weight of the wheels is unbalanced by removing one or more weights from each wheel. In this manner the wheels are made heavier on one side than on the other. This increases the force of the vibrations and would make vibrations independently of the motor if the wheels were revolved.
The advantage of two sets of rollers is that the front set of rollers will accomplish the greater partof the work of removing the air and surplus water from the concrete and the second set will complete the work of direction or course after the first set of.
Air bubbles that are directed.
rollers pass over. The second set of rollers force a continuance of removal of the air and surplus water until all the air and surplus water are eliminated from the mass of concrete.
The fiy-wheels are thus provided with removable weights so that more or less vibration can be obtained by increasing or decreasing the out-of-balance of the wheels. The machine rolls easily while transmitting vibrations and pressure through the transmitting unit (consisting of stringers 17 and cleats 18) to the concrete, squeezmg out the air and excess water with remarkable efliciency. The machine has been thoroughly demonstrated under service conditions and found to be highly eflicient. The perfected machine has reached the present state of efficiency by numerous experiments with various forms of the vibrator.
The transmitting unit may be varied as the essential'function of this unit is to transmit the vibrations and pressure to the plastic concrete mass and at the same time permit the air and surplus mortar to escape through the transmitting unit. The surplus mortar may then be cleaned ofi' of the finished concrete. i
What I claim, is,-=
1. A vibrating machine comprising an operating motor and fly-wheels actuated thereby, a hanger therefor bolted rigidly to said motor, shafts mounted in said hanger variable means for unbalancing said fiywheels, and rollers mounted on and balancing said shafts for transmitting the vibrations of said machine.
'2. A vibrating machine in combination with a transmitting unit comprising an operating motor provided with fly wheels actuated thereby, a longitudinal .frame operatively connected with said motor, a
plurality of rollers journaled at each end of said frame for engaging said transmitting unit, andmeans insertable into and removable from said fly wheels. for varying the unbalancing effect of said fly wheels.
3. The combination of a vibrating machine and an element for-transmitting the vibrations thereof to a concrete mixture comprising a motor and a frame therefor, fiy wheels journaled in said frame and actuated-by saidmotor, means insertable into and removable from said fly wheels for varying the unbalancing effect of said fly wheels, shafts journaled in said frame, and rollers for supporting said shafts and engaging said transmitting element I 4. A vibrating machine comprising an operating motor provided with a frame having laterally projecting flanges, fly-wheels operated by said motor, a hanger bolted rigidly to sand flanges, front and rear shafts mounted in said hanger, rollers mounted on said shafts, and variable means for unbalancing said fly-wheels;
5. A vibrating machine comprising an opcrating motor provided with a frame having laterally projecting flanges, fly-wheels operated by said motor, a hanger bolted rigidly to said flanges and consisting of two longitudinal members and ,a web connected to said longitudinal members for bracing ROBERT STUBBS;
