Inventor /J G. al/mron wwwvm Patented Aug. 18, 1931- UNITED STATES PATENT OFFICE TAMPINZG AND ROLLING MACHINE OPERATED BY VIBRATION Application filed Mine 7, 1929,
My invention relates to improvements in and connected with tamping and rolling machines operated by vibration and is based on the principle of a fly-wheel off the balance and running at speed setting up vibration, all
as hereinafter described with reference to the drawings and pointed out in the claim.
In order that my invention may be proper- 1y understood and readily carried into effect, I have hereunto appended two sheets of drawings, of which Figure l is a side elevation of a machine illustrating my invention.
Figure 2 is a cross section through the roller-shaft.
Figure 3 is a cross section through the tamping arrangement.
Figure 4 is a side view of the tamping arrangement showing two shafts carrying oil"- 'the-balance-fly-wheels.
The machine consists of a roller or wheel or a series of rollers or wheels A with handle B similar to a hand arden roller. The shaft C inside the rollers runs free in the rollers or Wheels A and also in the arms D at each side of the rollers or wheels A. The handle B being attached to the outside arms D. The arms D are connected to each other by a crossbracket E to which there is fixed a petrol engine F which (through a gear-box if desired) by means of sprocket-wheels G and fixed respectively on the engine crank-shaft I and the free-shaft C in'the rollers or wheels A and a chain J rotates the free shaft C in the rollers A, or the petrol engine may be fixed to any other convenient part of the machine.
At the front of the rollers or wheels A, there is a Hat bottomed metal base K attached to the free shaft C in the rollers or wheels A by one or two rocking arms L, the shaft still running free in these arms L. The top of the metal base K is formed to carry a shaft M and on this shaft M there is or are keyed one or more off-the-balance-flywheels N (the shaft is off dead centre in the wheel or wheels, or they are weighted on one side). Fixed to this shaft M there is a sprocket-wheel O, and by means of a sprocket-wheel P on free running shaft C in rollers or wheels A and a chain Q, this shaft M carrying the off-theregular ground, each section "Independent drive from shaft Serial No. 369,199, and in Great Britain June 27, 1928.
balance-flywheels N will be driven by the engine through the free running shaft C in the rollers shaft C carrying the oif-the-balance-wheels N will set up vibration, which vibration will be communicated to the material being packed in a tamping or dancin motion by the shaft M carrying the base with it, lateral shock being taken up through the arms L by the free running shaft C in the rollers or wheels A. The rotation of this or wheels A. Suitable springs S are fixed between the rocking-arms L and an extension bracket T formlng part of cross-bracket E to provide a damper against excessive vibration of the rocking-arm L.
ith reference to the tampin arrangement, Figure 4, this shows a base I supported by two shafts M suitably geared together by gear wheels R suitably fixed to the shafts M, these shafts M being driven by the chain Q. Each shaft M has two or more outof-balance-flywheels N fixed thereto so as to work synchronously, i. e., these eccentric flywheels N are so relatively connected together by the gear wheels R that they simultaneously and equally advance toward and recede from each other during the operation of the device and effect a combined tamping action.
In place of having one large tamping base for wide areas, this may be made in sections in order to secure greater contact on irmay have an O.
y invention will be specially suitable for the tamping of concrete, packing of filled in ditches, drains, and such like, tamping in of tar macadam, asphalt, and the like on roads and for the tamping in or filling up of potholes in roads and also in gardening footpaths and inside buildings.
The advantages obtained by my invention are that a tamping motion is superior for the packing of material to that of rolling it in by a slow moving weight, much greater solidification being obtained. The-machine can be made in any size, is portable, can be moved about and worked by one man, is cheap to construct, easily operated, and will have a long working life as the engine is isolated from all shock of the vibration. As the en- "gine is only driving the shaft carrying the fly-wheels-of-the-balance, a very low H. P. is required. As the vibrations are delivered to the material being tamped at a very high number of blows per minute, the machine can be pushed about by a man as desired when engine 'is working. When moving from one place to another with engine stationary, the
I metal base forming thetamper will, by means of-a meta-l rod attached to the framework carrying the petrol tank and to the top of the tamper, be lifted clear of the ground.
lhe machine may be provided with suitable means by which the engine can be suitably geared to enable the machine to be mechanically driven.
Claim:
A tamping and rolling machine comprising a bracket, a shaft rotatably mounted in said bracket, rollers freely mounted on said shaft for supporting said bracket, a pair of arms freely mounted on said shaft at each side of the rollers, a cross-bracket connecting the arms together, a metal base having upstanding bearings supported by the free ends of said arms, a shaft freely carried by said bearings, an ofi-the-balance fly wheel keyed to said second shaft, means carried by said bracket for driving said first shaft, and a driving connection between the two shafts.
