The margins on each edge of the strip may then be successively removed With a usual cutter employed for such purposes.

Thereafter the margins may be removed from additional strips cut from the roll of wall paper Without the necessity of measuring the same or Y locating the straightedge thereon with a rule.

The above described operation may be equally as well carried out With strips having margins of unequal Width. In such instances the pointers 22 are utilized to locate the straightedge for the narrowest while the pointers 23 are utilized to locate it for the widest margin.

From the foregoing it will be apparent that the straightedge of the gauge may be easily and quickly located to properly position it 'on strips cut from a roll of Wall paper for removal of the blank margin thereon without the use of rules or the like.

I claim:

1. A gauge of the characterY described comprising in combination a straightedge, a rock shaft disposed lengthwise of and mounted on said straightedge, a pair of arms slidably mounted on said shaft, a pair of blocks slidably mounted in each of said arms, pointers secured to said blocks, and means for adjusting said blocks whereby the pointers thereon may be adjusted in relation to the edge of said straightedge.

2. A gauge of the character described comprising in combination a straightedge, a rock shaft disposed lengthwise of and journalled in a bearing mounted on said straightedge adjacent each formed in said arms, and nuts threaded on said 20 studs for adjusting the latter pair of blocks on said arms for the purpose set forth.
