UMBRELLA TIP. APPLICATION FILED JULY 28, 1919.

SIMON I. GOLDSTEIN, OF BALTIMORE, MARYLAND.

UMBRELLA- TIP.

Application filed July 28, 1818.

1 b (M whom it may concern:

Be it known that I, SIMON I. GoLns'rniN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Umbrella-Tips, of which the following is a specification.

This invention relates to improvements in devices for detachably connecting the margins of umbrella covers to umbrella ribs, and it comprises a hollow tip with means for readily attaching the same to and disconnecting it from the corners of adjacent sections of an umbrella cover, and means whereby the tip, attached to the cover, may readily be connected to or disconnected from an umbrella rib.

The details and advantages of my invention will be clear from the specification, taken in connection with the accompanying drawing, in which,

Figure 1 is a side elevation, taken from the outside of the cover, showing one of the attaching devices in position upon an umbrella rib;

Fig. 2 is a similar view taken from the inside of the cover, the rib being omitted;

Fig. 3 is a view similar to that shown in Fig. 2, showing the devices mounted upon a hollow umbrella rib;

F ig, 4: is an enlarged view taken in section on the line 4l of Fig. 3,

Fig. 5 is an enlarged section on the line 55 of Fig. 3;

Fig. 6 is a section on the line 66 of Fig. 4;

Fig. 7 is a perspective view of the end of a hollow umbrella rib;

Fig. 8 is a longitudinal section through the adjacent device, showing the same connected to a solid umbrella rib; and,

Fig. 9 is a section on the line 9---9 Fig. 8.

Referring to Figs. 1 to 7, inclusive, of the drawing, (4 indicates a hollow tip comprising a tubular portion 1, which may be cylindrical, but is preferably slightly tapering from its open end to its closed end 2, which latter is preferably globular in' form to resemble the tip of an ordinary umbrella rib, which usually terminates in a small sphere. A tapering pin 6 is adapted to fit within the tubular tip, and this pin is preferably angular in cross section, as shown in Figs. 4. and 6. The base of the tapering pin is rounded, as shown at 3,

and extending from the base is a cylindrical projection a, adapted to fit within the end of a hollow umbrella rib 5. The rib 5 is formed like the ordinary hollow umbrella rib, U-shaped in cross section, except that its end portion 5 is bent into cylindrical form and cut ofl squarely instead of termi nating in a tip.

In applying the device to an umbrella, the corners of adjacent sections 6 and 7 of the cover are inserted within the tubular tip a and the tapering pin is then firmly pressed into the tip and the end portions of the sections are thereby wedged firmly between the pin and the tip. The purpose in making the body of the tapering pin angular is to provide corners 8 on the pin, for gripping the cloth, and spaces 9, between the fiattened faces 10 of the pin and the inner wall of the tip, into which the cloth may expand when pinched between the corners and the tip. After the sections of the cover have been secured within the tip by the pin, as shown in Fig. 2, the extension at is inserted within the tubular end of the umbrella rib, as shown in Figs. 3 and 4, and the shoulder formed by the base 3 of the pin then rests against the end of the rib, in which position it is held by the tension of the cloth along the line of the seam between the sections. To detach the cover from the ribs, it is only necessary to grasp the attaching devices and pull outwardly upon them until the extensions 4 leave the cylindrical portions of the ribs. hen an attaching device is disconnected from the rib, as shown in Fig. 2, if it is desired to remove the attaching device from the cover, it is merelynecessary to grasp the stem or extension 4 in one hand and the tip a in the other and pull them apart, and this releases the cloth. The facility with which the device may be disconnected from the cloth is an important feature of the invention. Separable tips, generally, are secured permanently to the cloth and usually there is a loss of time and injury to the goods by the removal of the tip therefrom, whereas, in the present invention, the goods are not injured either by attaching or detaching the tip and very little time is required for either operation. Thus, if it is necessary to remove a torn or defective section from an umbrella fitted with the tips of my invention, the cover can be disconnected from the rib and the attaching deseam between the sections, and the cloth is not drawn over any sharp edges or corners I at the point where it emerges from the tip.

The rounded shoulder 3 is provided in order to prevent injury to the cloth when the umbrella is rolled after being closed.

In Figs. 8 and 9, I have shown the invention applied to a solid umbrella rib 5. Such ribs are usually of small diameter and in order to provide a socket for receiving the stem 4 of the tapering pin Z), I arrange upon the end of the solid rib a short piece of tubing 11, into which the stem 4 extends. Preferably this piece of tubing 11 is fixed to the rib 5 and receives the stem 4 loosely; but, if desired, the tubing might be secured to the stem and extend loosely over the end of the rib.

While I have shown a tapering pin of hexagonal cross-section, it will be understood that the form of the pin may vary in cross section and may be either round or angular, although the latter form is preerred in order to provide gripping edges with intermediate spaces for 'recelving the cloth. 1 Y

" 'l/Vhat I claim is:

1. Means for attaching covers to umbrella ribs comprising a tubular tip adapted to receive the corners of adjacent cover sections, and a tapering pin. adapted to fit into the tip and bindsaid corners therein, said pin adapted to telescopically engage the end of an umbrella rib.

2. Means for attaching covers to umbrella ribs comprising a tubular tip adapted to receive the corners of adjacent cover sections and a tapering pin adapted to fit into the tip and bind said corners therein, said pin having a shoulder adapted to abut against the end of a rib and having an extension. from said shoulder adapted to telescopically engage the rib.

3. In an umbrella, a rib having a hollow outer end, a tubular tip adapted to receive the corners of adjacent cover sections and a tapering pin fitting within the tip and binding said corners therein, said pin having a shoulder adapted to abut against the end of the rib and having an extension adapted to fit telescopically within said hollow end.

4:. A device for attaching-umbrella covers to ribs comprising a tubular tip and a tapering pin adapted to fit into said tip, said pin being angular in cross-section and having a shoulder at its base and having an extension from its base adapted to telescopically engage the end of an umbrella rib.

5. A device for attaching umbrella covers to ribs comprising a tubular tip and a tapering pin adapted to fit into said tip, said pin being angular in cross-section and having a rounded shoulder at its base and having an extension from its base adapted totelescopically engage the end of an umbrella rib.

In testimony whereof I afiiX my signature.
