IMPROVEMENT IN UMBRELLA-RUNNE'RS.

Specication forming part of Letters Patent No. 200,609, dated February 26, 1878; application filed January 17, 1878.

.ToA all whom t may concern:

Be it known that I, HENRY S. FROST, of Watertown, county of Litchfield and State of Connecticut, have invented a new and useful represent the blank in various stages of manufacture, and Figs. 6 and 7 the finished artic e.

To enable others skilled in the art to make and use my invention, I will proceed to describe iully the method which I have devised for producing the same.

A, Fig. 1, represents a flat disk of metal, preferably of brass, which is rst drawn in the usual well-known or any other proper manner, as indicated in Fig. 2, until a tube, a, Figs. 3 and 3, is formed of the proper diameter for the head of the runner which is to be made.

The part designed for the Cylinder portion is then further reduced in size,.as shown in Fig. 4, in a similar manner until its proper diameter has been reached. The head of the Arunner is then crimped, as indicated in Figs. 5 and 5a, by any suitable means to form an A horizontalv groove, c2, Figs. 6 and 7', is then formed in the head by means of a saw, for the reception of the binding-wire for securing the stretchers in place. A

By the employment of themethod described a runner is obtained which is a single .solid structure, instead of being composed of' several pieces, as has been the case heretofore. By means of this method, also,'a highlyiinished runner may be readily made-a result impossible'to be accomplished with the old forms of construction. By means of this method, also, the labor and cost of making the runner are materially reduced.

I am aware of the patent of A. G. Davis,

No. 75,881, March 10, 1868; but the runner i secured by this is not made in a single piece. I am also aware that a differently constructed runner has been made in a single piece by a different method.

Having thus described my invention, Iclaim and desire to secure by Letters Patent- 1. The described method of making the runner, consisting, essentially, irst, in drawing a metal disk into a tube with an enlarged head 5 secondly, crimping the head to form the vertical nicks al and,thirdly, sawing the horizontal groove a2.

2. As a new article of manufacture, a runner made in one piece, having an enlarged head provided with the crimped vertical nicks and the horizontal slots, as set forth.

This specification signed and witnessed this 8th day of January, 1878.

HENRY S. FROST.
