Abstract

The asphalt tamper includes a tamper plate connected to a reciprocating rod that oscillates inside of a protective sleeve, wherein the reciprocating rod abuts a cam that rotates about the output of a motor. The reciprocating rod has a shoulder that interacts with a spring that applies a biasing force ushering the reciprocating rod back and forth upon interaction with the rotating cam.

Claims

1. A hand-held tamping device for use in tamping asphalt or stone comprising:

a motor being connected to a rotating cam, said cam rotating in abutment with a reciprocating rod being spring-loaded via a spring acting upon a shoulder located on said reciprocating rod;

wherein a sleeve extends along the reciprocating rod, and is made of a material comprising a metal, rubber, carbon fiber, or plastic;

wherein the reciprocating rod has an overall length no less than 3 feet;

wherein the shoulder of the reciprocating rod and spring are located in a sub-housing extending from below the housing;

output of said motor is adjusted via a variable speed control that regulates the output speed of the motor;

wherein the variable speed control is positioned on an exterior surface of the housing;

said motor being powered by at least one rechargeable battery that is located within a housing, and wherein said rechargeable battery being recharged upon connection with a recharging cord;

wherein handles protrude from the housing and provide a means for handling the tamping device by a single individual;

wherein an on/off switch is positioned upon one of the handles and controls operation of the motor;

wherein a bottom end of said reciprocating rod being connected with a tamper plate that upon reciprocation impacts ground being tamped.

2. The tamping device as described in claim 1 wherein the reciprocating rod and tamper plate are made of a metal.

3. The tamping device as described in claim 1 wherein the sub-housing and the housing are made from materials comprising a plastic, metal, or carbon fiber composite.

4. A hand-held tamping device for use in tamping asphalt or stone comprising:

a motor being connected to a rotating cam, said cam rotating in abutment with a reciprocating rod being spring-loaded via a spring acting upon a shoulder located on said reciprocating rod;

wherein the reciprocating rod has an overall length no less than 3 feet;

the spring and shoulder of the reciprocating rod are housed inside of a sub-housing that extends from below a housing;

output of said motor is adjusted via a variable speed control that regulates the output speed of the motor;

said motor being powered by at least one rechargeable battery that is located within the housing, and wherein said rechargeable battery being recharged upon connection with a recharging cord;

wherein handles protrude from the housing and provide a means for handling the tamping device by a single individual;

an on/off switch is positioned upon one of the handles and controls operation of the motor;

wherein a bottom end of said reciprocating rod being connected with a tamper plate that upon reciprocation impacts ground being tamped;

wherein the reciprocating rod and tamper plate are made of a metal;

a sleeve extends down from the sub-housing along the reciprocating rod.
