US Patent:

44425996, Apr 17, 1984

Filed:

Nov 12, 1981

Appl. No.:

6/320724

Inventors:

Frederick G. Clark - Naples FL

Assignee:

Eastman Machine Company - Buffalo NY

International Classification:

B25F 300

US Classification:

30139

Abstract:

A sharpener drive for the straight blade of a fabric cutting machine receives its motion from the crank wheel which drives the blade. A drive wheel, which selectively engages the crank wheel, drives a gear train which drives a gear mounted in splined relationship with an elongated shaft. A sharpener is mounted on the elongated shaft for selective engagement with the straight knife. An actuator is attached to the elongated shaft for sliding the elongated shaft through the gear with which it is splined to thereby move the sharpener axially of the knife while the gear rotates the elongated shaft to drive sharpener wheels. A link is engageable by the elongated shaft in its stored position for effecting disengagement of the drive wheel from the crank wheel. A latch includes a camming portion for moving the latch into locking engagement with the cutting machine housing when the elongated shaft is moved to its stored position. The sharpener consists of first and second sharpener wheels at a lower and higher elevations, the placement of the sharpener wheel at the lower elevation being for compensating for the upward movement thereof inherent in its linkage before it can engage the sharpener blade on the upstroke of the sharpener.

Assignee:

Eastman Machine Company - Buffalo NY

International Classification:

F01M 100

US Classification:

184 614

Abstract:

A cloth cutting machine having an improved lubrication system therein including a motor mounted on the machine housing for driving a crosshead supported in a crosshead guide through link means, and a lubricant reservoir positioned above the crosshead and having a plurality of wicks emanating therefrom for conducting lubricant to areas of contact between the crosshead and the crosshead guide and between the crosshead and the linkage which drives it.

Appl. No.:

5/725129

Inventors:

Frederick G. Clark - Naples FL

Assignee:

Eastman Machine Company - Buffalo NY

International Classification:

B25F 300

US Classification:

30139

Abstract:

A guard and sharpener construction for a rotary cutting machine having a base, a circular knife mounted on the base, a motor for driving the circular knife, a standard for mounting the motor above the base, an elongated slotted rod slidable to cover a segment on the leading edge of the circular knife, a pair of sheet-like guard members mounted on the mounting arms for the sharpener wheels, the guard members covering opposite sides of the knife above the segment, a pivotal shaft and associated mechanism for mounting the arms for movement between a sharpening and a non-sharpening position, with the rod member, the sheet-like guards and the sharpener arms being so oriented relative to each other so as to permit the sharpener to be used in all positions of the rod-like guard member, and a keyway and set-screw indexing structure for mounting the arms on the pivotable shaft.
