Abstract

The carpet and stripping machine includes a frame supported by wheels, an elongated handle, an electric motor, blade and a driving connection between the blade and the motor. The improvement of the invention resides primarily in the drive connection which causes the blade to oscillate straight back and forth without any side to side component to its motion.

Claims

1. A carpet and tile stripping machine comprising:

a. a frame;

b. a pair of wheels rotatably mounted on the rear of the frame;

c. handle means projecting from the frame for guiding the stripping machine;

d. motor means mounted on said frame, said motor means including a drive shaft projecting generally vertically through said frame;

e. eccentric means coupled to said motor shaft for producing orbital motion in a substantially horizontal plane;

f. a cutting blade mounting assembly positioned in front of said frame, said mounting assembly including a blade mounting portion, a first elongated drive bar, and a pair of tabs located on opposite sides of said drive bar;

g. a cutting blade secured to said cutting blade mounting assembly;

h. a second elongated drive bar secured at one end to the eccentric means and pivotally connected at its other end to the first elongated drive bar;

i. a first bearing comprising a housing and a push rod, said housing secured to the frame on one side of said second elongated drive bar and said push rod having one end slidably received within said housing and its opposite end secured to one of the tabs on the cutting blade mounting assembly, and a second bearing comprising a housing and a push rod, said housing secured to the frame on the other side of said second elongated rive bar and said push rod having one end slidably received within said housing and its opposite end secured to the other of said tabs on the blade mounting assembly, said first and second bearings along with the pivotal connection between said first and second elongated rive bars serving to eliminate any lateral motion of the cutting blade mounting assembly so the cutting blade only moves back and forth in a straight line path of travel with respect to the frame in a selected horizontal plane.
