UMBRELLA-RIB AND STRETCHERv-JOINT.

SPECIFICATION forming part of Letters Patent No. 698,267, dated April 22, 1902.

Application filed January 24, 1902. Serial No. 91,096. (No model.)

T all whom it may concern: y

Beit known that I, SAMUEL J. EVANS, a citizen of the United States, residing at Roanoke, countyof Roanoke, Virginia, have invented certain new and useful Improvements in Umbrella-Notches, of which the following is a specification. i

Myinvention relates to umbrellas,- and particularly to aspring-notch adapted to permit the ready insertion or removal of the ribs or stretcher-s when they are properly manipulated under suitable pressure.

The invention is shown in the accompanying drawings, in Which-'- Figure 1 is a sectional `view showing the upper notch and a runner-notch in position upon a stick. Fig. 2 is a side view of the upper notch. Fig. 3 is adetail sectional view illustrating the action of the devicee.

In the drawings, l indicates the stick, which may be of ordinary form.

My present arrangement is an improvement upon that disclosed in an application forLetters Patent of the United States, iiled by me June I, 1901, Serial No. 62,765.

The notch proper is shown at a. This notch has a socket to receive the headed ends of the ribs and a contracted mouth 3, through which the heads may be passed when in a certain position, as described in said-application.

In my present invention I provide means for preventing the outward movement of the heads through the contracted mouths except when the device is properly manipulated to permit this removal. This means consists of a ferrule or sleeve 4, secured to the sleeve or extension 5 of the notch ring and having spring-fingers 6 extending toward the socket of the notch, so that the extreme end edge of said fingerswill provide stops or abutments for contact with the ribs or heads to prevent their disengagement. The arrangement is such that one` of the spring-fingers is located oppositeeach one of the contracted mouths of the notch. When it is desired to remove a rib, the corresponding spring-finger must be pressed inwardly, as shown on the left of Fig.

" 3, so that the end edge thereof will be removed from the path of the head. It will be seen from the above that this arrangement pro- `'tudes a spring retaining or closing wall for the socket of the notch and that it is necessary topress this spring part inwardly toward the stick before the rib can be removed. While this arrangement provides a retaining part capable of being sprung inwardly when the rib is being placed in position or removed, it will be understood that when 'the head is in place within the notch the end edge of the' finger will present a substantially rigid abut-` ment or stop directly across the line or path that the rib must take in passing outwardly pressure when applied to move it laterally y away from the path ofthe rib or the head thereof.

I I do not wish to limit myself either to the precise form of notch shown and.A described.

The sleeve carrying the spring-fingers is $6-,

cured to the notch extension preferably by being soldered thereto.

In the ordinary operation of the umbrella the spring-fingers yield as the ribs or stretchers press against them.

Where I refer in the claim to the ribs I mean this term to include also the arrangei ment when applied to the stretchers. p

I claim as my invention- In combination, the ribs, a notch havinga series of months through which the ribs pass and spring parts toretain the ribs in the notch, said parts consisting of flat springs having their terminal edges extending across the said mouths from one side to the other and in the plane through which the ribs must pass when being removed, substantially as described.

In testimony whereof I affixy my signature in presence of two witnesses.

SAMUEL J. EVANS.
