SPECIFICATION forming part of Lea-ere Patent No. 728,035, dated m 12, 1903."

.' Appli0ation filed Au us aieoa Serial No. 118.,181. (Nomod'eld In umbrellas and especially those of larger,

sizes considerable difficulty has been experi-' enced in fastening the outer ends of the ribs, Metallic tips have been em.-' ployed, which are attached in various Ways to the covers.

directly to the covers; but these devices often tear out, and thereby injure the fabric.

One of the features of the present invention resides in the construction of the tip,

which is made up of. sections adapted ,totbe clamped upon fabric in such a manner that there is little liability of its tearing-the same.

Another feature relates to the means for fastening the tipto a cover, said means reinforcing the cover,'and thus strengthening the same. As a result the danger of tearing is reduced to a minimum and an efficient wellseoured tip is provided.

The preferred embodiment of the invention is fullyillu'strated in the accompanying draw-' ings and is described. in the following specification, though it willbe apparent upon an inspection of the'claims that the structure herein shown and described is open to various changes and modifications.

In the drawings, Figure 1 is a plan view of the under side of a portion of the umbrellacover, showing a part of one rib and the manner of connecting it to the cover. Fig. 2 is a longitudinal sectional View of the same on an enlarged scale and taken on the line a; at of Fig. 1. Fig. 3 is a cross-sectional view. Fig. 4 is a perspective viewwith the elements partially disassociated to more clearly illustrate the manner of securing them together. Figs. 5 and 6 are perspective views of the tipsections.

designated by -10 and the rib by 11. These .may be of any desired material well-known tofthe art. The means for fastening the rib to the cover is in the form of a tip comprising clamping- sections 12 and 13 and a reinforcing-patch 14:.

The section 12 of the tip consists of a body having a longitudinal open-sided groove 15, that extends from one endandsterm'inates short of the other, this groovebeingnpreferablyformed by upsetting the,bo.d'y,' as shown in Fig. 6. The side edgesof the section are provided'on opposite sides of the groove 15 with notches 16. The other section 13 is arranged to fit over the section 12, and constitutes a cap which covers the open side of the groove 15, thereby forming a'socket or seat for the reception of the end of the rib 11'. This cap preferably has a slight longitudinal depression 17in its un der face whi'ch'alines with the groove 15. Depending spurs 18 are arranged on the opposite side edges of the cap-section, said spurs being adapted to engage in the notches 16 and be bent over the outer face of the section 12,'as clearly shown evident that the comparatively-great amount of surface clamped thereby Willsecurely hold the tip against tearing out. This holding action is furthered because of the patch being of strong material. When the tip has been thus securedthe parts are in the relation shown in Fig. 4:. The patch is then turned against the under side of the cover and switched to the same. As a result the strain will be almost entirely'on the seam, and what little strain there is otherwise will be distributed through the patch overa com-. paratively large area of the cover. Thus it The reinforcing-patch 14 I will be apparent that the fastening means as a whole is very strong and the tip will not readily tear from its fastenings. The several elements going to tnake up the above are extremely simple and easily constructed, so that an umbrella made in accordance with the present invention can be manufactured at comparatively small expense.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art with-.

out further description, and itwill be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

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

1. An umbrella tip comprising socketclamping sections arranged to engage opposite sides of a piece of fabric, one of said sections having a rib-receiving seat, and means adapted to be passed through the fabric for securing the sections together.

2. An umbrella-tip comprising separate clamping-sections arranged to engage opposite sides of a piece of fabric, one of said sections having a rib-receiving seat, and spurs carried by one section, said spurs being arranged to be passed through the fabric and bent over the other section.

3. An umbrellatip comprising separate clamping-sections arranged to engage opposite sides of a piece of fabric, one of said sections having a rib-receiving seat, and spurs carried by one section, the other section havingsockets, said spurs being arranged to be passed through the fabric, engaged in the sockets of the other section, and bent over said section.

4. A tip for umbrellas, comprising separate coacting clamping-sections, one of which is provided with an open-sided groove constituting a rib-receiving seat, the other section constituting a cap that covers the open side of the groove, and means for securing the sections together.

5. A tip for umbrella-s, comprising separate coacting clamping-sections, one of which is provided with an open-sided groove extending from one end and terminating short of the other end said groove constituting a ribreceiving seat, the other section constituting a cap that covers the open side of the groove, and means for securing the sections together.

6. A tip for umbrellas, comprising separate coacting clamping-sections, one of which is provided with a groove extending from one end and terminating short of the other end forming a rib-receiving seat, said section having sockets located on opposite sides of the groove, the other section constituting a cap that covers the open side of the groove, and spurs carried by the cap-section, said spurs being arranged to engage in the sockets and be bent over the section containing thesame.

7. In an umbrella, the combination with a cover, of a tip comprising clamping-sections, a patch secured between the clamping-sections and fastened to the cover, and a rib engaging the tip.

8. In an umbrella, the combination with a tip comprising a pair of clamping-sections, of a cover, a patch secured to the cover, said patch and cover having portions engaged between the sections, and means for securing the sections together.

9. In an umbrella, the combination with a tip comprising a pair of clamping-sections, one of which has a socket, of acover, a patch secured to the cover, said patch and cover having portions engaged between the sections, spurs carried by one section, said spurs passing through the patch and engaging the other section, and a rib engaging in the socket of said section.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses JAMES H. SPRAGUE.
