SPECIFICATION forming part of Letters Patent No. 289,229, dated November 27, 1883.

Application filed August 28, 1883. (No model.)

lbotZZ whom it may concern:

Be it known that I, JOHN N. COLBY, a citizen of the United States, and a resident of.

which I applied for Letters Patent of the IO United States on the 9th day of May, 1888,

serial number of application 94,365.

My present improvements relate to the runner, to the device for securing the stretcher thereto, to the connection between the runner audits surrounding ferrule, to the device for retaining the runner when the umbrella is raised, and to the means for securing the cover of the umbrella to the ribs.

In the accompanying drawings, Figure 1 is Fig. 2, a sectional plan on the lines 1 2; Fig. 3, aperspective view of the runner; Fig. 4, a perspective view of one of the stretcher-con nections; Fig. 5, a sectional View of the retainer for the runner when the umbrella is raised; and Fig. 6, a view of the tip end of one of the ribs, showing the method of attaching the cover; Fig. 7, a perspective view of one oft-he cover-retaining rings. All of these views are drawn to an exaggerated scale.

A is the stick of the umbrella, which has longitudinal grooves for the reception of the hollow ribs B and stretchers D, as in the former case.

F is the runner, which consists of a corrugated tube adapted to fit snugly to the grooved stick, and free to-slide thereon. This tube is seamless, being formed by drawing or forcing a seamless tube through dies of the proper shape, thusproducin'g very cheaply a stronger and more accurate runner than can be made 1 bar, so that the latter is secured vertically to a vertical section of part of the umbrella,

the runner,and is compelled to move therewith. The wings f are slightly elastic, and bear with a yielding pressure upon the ferrule H, which incloses the runner, the friction be ing sufficient to cause the movement of the runner with the ferrule when there is no uncause the same to confine the tips of the ribs,

as in Fig. 1, or to release said ribs when it is desired to spread them. The objectionable screw or bayonet-j oint connection between the runner and its ferrule is dispensed with, the construction of the device being thereby cheap ened and the operation of the same simplified.

'The runner fits so snugly to the grooved stick that the friction between the two may be re lied upon to retain the runner in position when the umbrella is spread; but for additional security I provide one of the grooves of the stick with a spring-finger, 9, Fig. 5, whicln when the runner is elevated, bears against the upper end of the same, or against the projecting end of one of the stretcher-.80 bars, or both, and increases the friction. The ferrule H acts directly upon the tips of the ribs to retain the same, whether the ribs are bare, as when the device is used for a cane, or are provided with a cover, as when the cane 8 5 is formed into an umbrella, the same adjustment of the ferrule being made in either case. To permit the ferrule to act upon the tips of the ribs, the cover 00 must be secured to the latter some distance above the tips; hence I 0 reduce each rib at and near the end, so as to form a shoulder, to, Fig. 6, the cover at being provided at the outer edge with as many rings 3 as there are ribs, each ring being slipped o ver the tip and finding abearing against the 5 shoulder w,as shown in Figs. 6 and 7. Each ring has an eye, 3 by which it is secured to the umbrella; but the rings may be plain, if desired. Instead of relying upon the elastic wings f of the stretcher-bars for insuring :roo

proper frictional contact between the runner and ferrule H, the runner may have special elastic wings for this purpose; but, on the score of economy, the double use of the Wings f is preferred.

I claim as my invention 1. The seamless longitudinallycorrugated runner-tube F, asset forth.

2. The seamless longitudinally-corrugated runne -tube F, having external recesses, d, as set forth.

3. The conbination of the corrugated runner F, having recesses d, with the stretcherbars G, having Wings adapted to said recesses, as set forth.

4. The combination of the runner with the ferrule H, held in position thereon by friction, as set forth.

5. The combination of therunner, the ferrule H, and the stretcher-bars G, having elas- 2o tic fingers f, as set forth.

6. The combination of the stick A and the runner with the spring-finger 9, adapted to retain the runner by friction, as set forth.

7. The combination of the ribshavingshoul 25 ders w above the tips with the cover an, having rings y, adapted to bear against the shoulders. as set forth.

In testimony whereof I have signed my name to this specification in the presence of two sub- 0 scribing witnesses.
