To' LZ whom, t may concern.:

Be it known that I, WILLIAM WV. BEAM, a citizen of the United States, residing at Vogansville, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Umbrella Rib-Holders andfRunners, of which the following is a speciiication. wit-.a

This invention relates to new and useful improvements in umbrellas, and more particularly to the means whereby the stretchingribs are secured or attached to the runner.

The invention h as primarily for its object the provision of novel means whereby the parts may be assembled or disengaged to facilitate repairs.

The invention also has for an object the provision of novel heads for the ribs, said head being integral therewith.

Finally, an object of this invention is to produce a device of the character noted which will possess advantages in points of simplicity, efficiency, and durability, proving at the same time comparatively inexpensive to produce.

`With the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of, this speciiication, Wherein like characters denote corresponding parts in the several views, in which- Figure I is a view in elevation, illustrating the invention applied to a fragment of an uin- `-brella-staff. Fig. 2 is a vertical sectional view showing the staff in elevation. Fig. 3 is asimilar view showing the rib in a different position. Fig. 4- is a perspective view of the sleeve. Figs. 5 and 6 are perspective views showing the ribs in different stages of construction, the latter being complete. Fig. 7

a matter of convenience in the process of manufacture., I make the cage 2 a cup with a central opening in its top to slip over the tube of which tne runner l is formed and after placing the sleeve 7 on the ruimer slip the cage 2 in position and braze it fast. However, it might be screw-threaded or the runner-tube expanded like tubes are fastened in boiler-heads, or the upper end of the tube 1 turned over into a flange or bead on top of the cage 2, tlius firmly holding the same in its position on top of the ruimer l.

Loosely mounted, on the runner and positioned between the cage 2 and the bead 6 is a sleeve 7, which when held up .against the cage confines the ribs or the heads of the ribs therein and holds the same against displacement, and it is also the intention of the invention to have said sleeve confine the ribs within the cage when it is at the limit of its movement in an opposite direction or abutting the bead 6.

The upper edge of the sleeve is provided with an annular flange 8, which has formed therein the recess 9, the bottom of said recess being inclined upwardly. This sleeve is not only movable on the runner longitudinally, but rotates therearound, and when it is desired to remove a rib said recess is positioned beneath said rib, and the sleeve is withdrawn to contact with the bead 6, when said rib will be free to be withdrawn. Thus it can be seen by this arrangement any one of the ribs may be moved independently of the other. To hold the ribs positivelyl against displacement, a Wire 10- is coiled about the ruimer between the bead 6 and the lower edge of the sleeve 7. This wire is not resilient, but must' of necessity possess a certain amount of flexibility whereby it can be easily applied or readily removed.

It has been found in practice that the strain of the stretching-ribs on the iingers of the cage is so great as to bend the saine, and in order to obviate this great disadvantage it has been found well to enlarge the [lange a of the sleeve, as illustrated in Fig. 3, and to provide said ilange with a circular recess, in which the free portions of the projections Will extend when said sleeve is in its operative position or at the limit ofits up- Ward movement. greater portion of the strain of the stretcherribs is distributed. to the sleeve and will, it is thought, be readily appreciated.

Although it is not essential that any spe- IOO IOS

By this arrangement tne oific forni' of head should be supplied tothe ribs, it has been found in practice well to employ such as is illustrated in the' drawings, wherein is employed a laterally-extending head 13, which head is formed by rolling the end portion of the rib to form such head. By this means the head is formed integral with the rib and its strength and durability is greatly enhanced. i

In the construction of the head it might be well to state that the rib is U-sha ed and near the under portion is provider with a flat reinforcing-strip 12. The extreme portion ofthe rib is then flattened out, as shown in Fig. 5, and then rolled up upon itself to form a lateral head 13.

Having fully described my invention, what I claim as new, and desire to secure' by Letters Patent, is-

1. In combination, a runner,v a cage at one end of the runner, a bead formed on the runner intermediate its length, a sleeve loosely mounted on the runner between the bead and cage, a flange on the end of the sleeve adjacent the cage, a recess in the upper edge of the flange and a split ring embracing the runner intermediate the sleeve and thebead.

recess having its bottom inclined and a split ring embracing the runner intermediate the lsleeve and the bead.

3. In combination, aruniier, a bead formed on the runner intermediate its length, a sleeve loosely mounted `on the runner between the bead and cage, a flange on the end 'of the sleeve adjacent the cage, a recess in mounted on the runner between' the bead and cage, a flange on the sleeve, said flange having a recess in its upper edge, a split ring embracing the runner intermediate the sleeve and the bead, said flange being also provided with a groove to receive the ends of tlie cage.

In testimony whereof I affix my signature 6o in presence of two Witnesses.

WILLIAM W. BEAM.
