To all whom 'it may concern:

Be it known that I, HERBERT L. JOHNSTON, a citizenof the United States, residing at Troy, inthe county of Miami-and State of Ohio, have invented certain new and useful for Umbrella-Ribs, of which the followin"y is a specification.

The inventionI/(lates to improvements in tips for umbr l a ribs.

The objet/f the invention'is to provide a simple ang/ effective device for securing the fabric co/'er of the umbrella to the ribs in a manner which will permit the ready removal of the cover when desired but at the same time effectuall)v secure it in place when in position.

The invention consists in the constructions and combinations of scribed and set forth in the claims.

'In the accompanying drawings, I4`igure 1 is a verticalV sectional view on -an enlarged scale of a device embodying my invention, a portion of the cover and rib being shown in position therein. Figs. Q and 3 are perspective views of parts of the device. Fig. 4 is a modified form of sleeve. v

Like parts are represented by similar characterso'f reference in the several views.

The tip consists essentially of a cap, a, formed of sheet. metal, and a. sleeve, also of sheet metal. .The sleeve is preferably formed of resilient nature and provided with a longitudinal slit, l, on one side and with a liaring'end, 712. v The sleeve, however, may be, if desired, formed of a solid non-.resilient nature. A

In assembling the parts, the fabric of the cover c is placed over the open end of the cap and the flared end of the sleeve pressed into the same so that the fabric will lie between the sleeve and the cap. ..\n internal bead, al, is then formed on the cap by pressing themetal in, as ind- :ated in the sectional view, thus securing the fabric between the sleeve and cap at-tbis point. '.lhe distance between diametrically opposite points ou the bead will preferably be slightly less than the part` of the sleeve so as to provide an interlocking conn'cctiou bcvtweenthe two parts, and thus prevent the sleeve from working up out of the cap or the cap' from slipping oftl the fabric about the rib. This distance, however, might be substantially the same, or even less, the thickness of the fabric between the. bead and parts hereinafter dethe sleeve forming in effect an enlargement of the bead. When the bead 1s made 1n the outer cap it will 4cause the resilient sleeve to be contracted more or less, lbut when the rib, cl, is inserted the sleeve will spring out to accommodate itself to the size of the rib and also will beI caused to be impinged more firmly against the bead and thus more tightly) secure the fabric in position. After the ri is inserted in place the head thereof will serve to hold the fabric against the bottom of the cap and draw the same taut between the head and the flared portion of the sleeve, and thus further tend to secure the parts together'.

When a non-resilient sleeve is employed, the fabric will be clamped securely between the bead, a', of the cap and the rsolid wall of the sleeve. In this case the sleeve will always beA made large enough to accommodate the largest size rib.

Having thus described claim 3. In a device of the cha- 'acter described, a cover, an outer cover-receiving member, an inner rib-receiving' member. inserted therein, and au internal and external projecting portion on thel respective members between which thc. cover lies forming an interlocking joint, substantially as specified.

In a device of the character described, a cover, an outer cover-receiving member open at one cud, an inner open-ended 'ribreceiving member insertiblc within said outer member, said cover being located between said members an internal projecting portion on said outer member adapted to clamp the cover to the inner member, and an external projecting portion on said inner member lying within said outer member and beneath the internal projecting' portion thereof, substantially as specified.

2'. ln a device of the character described,l a cover, an outer cover-receiving member open at one end, an inner open-ended rib receiving member insertible within .said outer member, Isaid cover heilig located between said members said inner member being formed with a longitudinal slit and being of resilient material, an internal projecting portion on said outer member, and an external projecting port-ion on said inner member lying within tbc outer member and beneath the internal projecting thereof, substantially as specified.l

port-ion lio 4. In a device of the characterdescribed,

a cover, an outer cap, a sleeve inserted therein having a flaring end, and an internal rib 'in said cap above said flared end of the 5 sleeve adapted to clamp the cover to the sleeve, substantially as specified.

5. In a device of the character described, and in combination with the fabric cover and rib, of an outer cap to receive the fabric, an inner sleeve adapted to be inserted inside the fabric in said cap, and also adapted to receive the rib, the outer end of said sleeve being flared, an internal bead on said cap, said cover lying between said flared end and 15 said internal bead, substantially as specified 6. In a device of the character described, and in combination with the cover and rib, olf-an outer cover-rece'iving cap, an inner ribreceiving sleeve, said sleeve being formed of resilient material and having a longitudinal slit, an vinternal bead Jformed on said outer cap, and a flared portion formed on the outer Aend of the sleeve beneath said bead, substarr tially as specified.

In testimony whereof, I have hereunto set :i my hand this 2nd day of December, 1908.
