No. 8566.-Improvement in Tailors' Measures.

What I claim as my invention, and desire to secure by letters patent, is the gauge designated by the letters A and S in the drawings. This gauge has two arms slit through the centre, from the cross bar down, as illustrated by fig. 1 in the drawings; the front arm extends up and forms a semi-circle over and around the top of the inner arm. This semi-circle is slit through the centre, and forms a way for the two shoulder straps, which are attached by a pivot to the top of the inner arm to turn on, with screws to set them to the desired place; the semi-circle is designated by the letter D in the drawings. This gauge moves horizontally on strap E, from the front backward, or vice versa, until it strikes the front of the arm-hole and locates the same, and is set by screws to the desired place. Again, this gauge can be drawn perpendicularly, so as to increase the length of the shoulders for a very full-breasted man, or contracted, so as to fit a hollow-breasted man.
