Filed:

Jul 11, 1975

Appl. No.:

5/595292

Inventors:

Charles Keith Stanfield - Matteson IL

Assignee:

B. & J. Manufacturing Company - Glenwood IL

International Classification:

B26B 300
B26B 902

US Classification:

30280

Abstract:

Manual tool used for trimming mold flash and protuberances from a tire has a handle with ends which are slotted to receive mounting flanges of a undulated sheet metal blade. The blade is so folded that its undulations comprise closely spaced ridges which extend from front to rear, are open on their underside and are united by narrow intervening webs. The underside of the lead edge of the blade is sloped along an arc and/or angle providing the blade with recesses in said leading edge between the ridges. The recesses have sharp cutting edges which cut entering flash close to the tire surface, the open under side of the ridges on either side of the webs providing clearance for missed flash and trimmings so that the tool blade is not raised off the tire surface in use of the tool.

Abstract:

A tire trimmer tool has an elongated handle and a U-shaped frame to which a blade of undulated sheet metal is detachably mounted. The undulations comprise closely-spaced parallel ridges which extend front and rear, are open on their underside and are united by narrow connecting webs. The undulations are arranged across the full width of the blade; and the outermost undulations which comprise the two sides of the blade have upturned walls, the edge of which seat is facing slots provided the legs of the U-frame; and an adjustable clamp which connects the two legs secures the blade in place. The fore end of the blade is sharpened on its underside and a narrow transverse portion of the blade therebehind is struck or turned upwardly across the full width of the blade and limits bowing of the blade in response to tightening of the clamp.
