Device for measuring surface projections on sidewalls of pneumatic tires

A device for measuring a raised area in the sidewall of a tire, including:

• a body having a generally U-shaped configuration with a pair of spaced legs and a cross member extending therebetween, each of said legs terminating in a free end adapted to be placed on the sidewall of the tire adjacent the raised area, and a channel formed in said cross member;
• a scale slidably mounted within the channel for movement generally parallel with the spaced legs to indicate the height of the raised area, said scale being a substantially thin flat rigid strip having measurement indicia thereon and terminating in first and second ends;
• a slot formed in and extending partially along the scale and terminating in first and second ends;
• and
• a fixed stop member on the body extending through the slot in the scale and engagable with the first end of the slot to position the scale whereby the second end of the scale lies in a common plane with the free ends of the legs, whereby said scale is slidably moved in the channel a distance equal to the height of the raised area upon the second end of the scale engaging the raised area of the tire.
