Abstract
Abstract A material cutting machine has an electric motor for reciprocating a cutting blade to cut material during movement of the cutting blade in both vertical directions. The motor has a crank wheel mounted on its shaft and connected through suitable means to the cutting blade for producing the reciprocating motion. An eccentric, which is mounted on the shaft of the motor, has its center on one side of the longitudinal axis of the shaft and diametrically disposed to the connection of the means to the crank wheel. A follower has one end resiliently biased into engagement with the periphery of the eccentric while its other end is adjustably connected to a flat, circular plate, which is adapted to engage the top of the material being cut by the cutting blade. When the cutting blade is moved upwardly, the plate is moved downwardly into engagement with the material being cut to prevent lifting of the material being cut by the cutting blade during its upward movement. The connection between the follower and the plate is adjustable to accommodate various total thicknesses of the material being cut.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A material cutting machine comprising: means to support material thereon for cutting; cutting means to cut the material supported on said materialsupporting means; means to engage the top of the material to exert a downward force thereon; means to reciprocate said engaging means relative to the material when said cutting means is in cutting engagement with the material; second means to reciprocate said cutting means whereby said cutting means cuts during movement in both directions; and said reciprocating means for said engaging means having means controlled by said second reciprocating means to reciprocate said engaging means in the opposite direction to the reciprocation of said cutting means.
Claim 2
Dependent Claim
107 words
A material cutting machine comprising: means to support material thereon for cutting; cutting means to cut the material supported on said materialsupporting means; means to engage the top of the material to exert a downward force thereon; means to reciprocate said engaging means relative to the material when said cutting means is in cutting engagement with the material; second means to reciprocate said cutting means whereby said cutting means cuts during movement in both directions; and said reciprocating means for said engaging means having means controlled by said second reciprocating means to reciprocate said engaging means in the opposite direction to the reciprocation of said cutting means.
Claim 3
Dependent Claim
167 words
A material cutting machine comprising: means to support material thereon for cutting; cutting means to cut the material supported on said material-supporting means; means to engage the top of the material to exert a downward force thereon; means to reciprocate said engaging means relative to the matErial when said cutting means is in cutting engagement with the material; motive means having a shaft; means to connect said shaft of said motive means to said cutting means to reciprocate said cutting means to produce cutting during movement of said cutting means in both directions; said shaft having an eccentric mounted thereon with its center disposed on the opposite side of the longitudinal axis of said shaft from said connecting means and diametrically disposed; and said reciprocating means for said engaging means having a follower connected to said engaging means and cooperating with the periphery of said eccentric to move said engaging means in the opposite direction to the direction of movement of said cutting means during reciprocation thereof.
Claim 4
Dependent Claim
167 words
A material cutting machine comprising: means to support material thereon for cutting; cutting means to cut the material supported on said material-supporting means; means to engage the top of the material to exert a downward force thereon; means to reciprocate said engaging means relative to the matErial when said cutting means is in cutting engagement with the material; motive means having a shaft; means to connect said shaft of said motive means to said cutting means to reciprocate said cutting means to produce cutting during movement of said cutting means in both directions; said shaft having an eccentric mounted thereon with its center disposed on the opposite side of the longitudinal axis of said shaft from said connecting means and diametrically disposed; and said reciprocating means for said engaging means having a follower connected to said engaging means and cooperating with the periphery of said eccentric to move said engaging means in the opposite direction to the direction of movement of said cutting means during reciprocation thereof.
Claim 5
Dependent Claim
25 words
The machine according to claim 2 including: resilient means acting on said follower to maintain said follower in engagement with the periphery of said eccentric.
Claim 6
Dependent Claim
46 words
The machine according to claim 2 in which: said engaging means comprises a substantially flat, circular plate engaging the material and surrounding said cutting means; and means to adjustably connect said plate to said follower in accordance with the total thickness of the material being cut.
Claim 7
Dependent Claim
15 words
The machine according to claim 1 in which said engaging means surrounds said cutting means.
