To all whom it may concern:

Be it known that I, JAMES M. BROOKFIELD, of Brooklyn, in the county of Kings and State of New York, have originated and designed a new Pattern for Telegraph-Insulators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, making part of this specification.

The drawing represents a side elevation.

This design consists in the combination, with the body or shaft, of two beads, one above the other, and an ogee-shaped top. The shaft is tapering from the bottom upward.

In the drawing, the letter A designates the body or shaft of my telegraph-insulator, which is tapering from the bottom upward. At the upper end of this shaft are two beads, a with an intervening

depression, C. The top B of my telegraph-insulator is ogee-shaped. By these means a telegraph insulator is produced which has an ornamental, novel, and distinguishing appearance.

What I claim as new, and desire to secure by Letters Patent, is--

The design for a telegraph insulator, consisting of a shaft, A, beads a b, intervening depression c, and ogee-shaped top B, as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 16th day of April, 1877.

JAMES M. BROOKFIELD. [L.S.]
