WATERPROOF PAPER UMBRELLA.

Application filed March 25, 1922. Serial No. 546,864.

To all whom it may concern:

Be it known that we, GEORGE B. CANNON, Jr., and FRANK W. HOWARD, citizens of the United States, residing at Brookl n, in the county of Kings, and at Mount ernon, 1n the county of Westchester, respectively, and State of New York, have invented new and useful Improvements in Waterproof Paper Umbrellas, of which the following is a specification.

This invention relates to umbrellas, and while features of the invention may be ap plicable to umbrellas having cloth covers, the invention is most useful when applied to the construction of inexpensive paper umbrellas.

The general object of the inventionus to produce an umbrella of this type having a cover which can be readily attached to the frame, and in which the frame and cover are constructed in such a way as to reduce the strains and prevent the cover from being torn from the frame by the wind.

Further objects of the invention will appear hereinafter.

The invention consists in the novel features, and in the general combination of parts to be particularly described hereinafter, all of which contribute to produce a simple and eflicient water-proof paper umbrella.

A preferred embodiment of the invention will be particularly described in the following specification, while the broad scope of the invention will be pointed out in the appended claims.

In the drawing,

Figure 11: is a erspective showing the portion of this strl at the fold where the direction of the strlp must change near the crown.

In practicing our invention we provide a frame very similar to an ordinary umbrella frame, that is to say, it comprises a stick 1, and ribs 2 which radiate from the umbrella The ribs 2, however, are mot hinged to the crown, but have flattened ends as illustrated in Patent No. 1,229,271, which are clamped by the crown against the side of the stick and are flexed when the ribs are extended by means of the stretchers 4 which are attached to a runner 5 on the stick. The umbrella cover 6 is composed of a plurality of sections 7, 7, etc., corresponding to the spaces between the ribs.

In applying the invention, sleeves 8 are provided which are attached to the inner side of the cover and extend inwardly from the outer edge of the cover. These sleeves preferably extend all the way up to a point at the crown, but near the e es 9 to which the stretchers 4 are attache these sleeves are provided with openings 11, respectively which ermit the outer end of the ribs to be inserted and slid outwardly, in attaching the umbrella cover.

Figure 5 illustrated the simplest construction for the sleeve, and for attaching the same to the adjacent umbrella sections. The two adjacent umbrella sections are simply held with their adjacent edges together and the side edges of a strip of paper are then sewed completely through the same by means of stitches 10. In this way, one row of stitches operates to form the sleeve and secure the two adjacent cover sections together.

.the ribs.

means or method maybe employed for the u'mbrella'construction at the crown. The invention disclosed herein relates especially to the means for connecting the ribs to the umbrella cover and for reinforcing the cover vided with an openlng or inclined slot 11 (see Figure 2) and at these slots the material of the sleeve is preferably reinforced by a short reinforcing strip 12 (see Figure 2). The ends of the umbrella ribs are provided with means toprevent them from injuring the cover in any way. This is preferably accomplished by providin enlargements or enlarged heads 13 on t e ends of This head may be formed simply by bending the end of the rib into a closed eye. It is important that these eyes should be completely closed because otherwise they tend to become caught in other parts and interfere .with the manufacturing of the umbrella. In order to strengthen the outer edge of the umbrella cover a string or cord 14 is laid along this edge (see Figure 3) and the edge is then turned over so as to form a hem 15 attached by stitches 16 to the body of the cover. The ends of this cord are attached together so that it operates to resist any force tending to enlarge the diameter of the umbrella at this point. Instead of having a diagonal slit 11 as shown in Figure 2, an opening 17 may be provided (see Figure 6). This opening is of oval shape and is such as would be formed by punching out a small area of the material. 11 this case also the material of the sleeve is preferably reinforced by a reinforcing piece 18.. In assembling the umbrella the enlarged head or eye in inserted through the slit and shoved outwardly down the sleeve, the head or eye 13 being smooth and round facilitates the thrusting of the rib through the sleeve-without injuring the paper, and after the rib is in place this head also tends to prevent the end of the rib from puncturing the paper near the edge of the cover.

The upper portion of the sleeve 8 lies between the rib and the cover and tends to distribute the pressure of the rib against the cover, thereby increasing the strength and durabflity of the umbrella at this point. The eye on the end of the rib is preferably formed in substantially the same plane as As a matter the axis of the umbrella stick (see Figures 8 and 9), that is to say, the plane inwhich the eye is formed lies substantially at right angles to the cover. After the rib has been slid down into place the projecting end portion 19 of the sleeve is then folded around so as to lie over'the eye or head 20. This folded over end can then be secured to the eye by any suitable means, for example, by means of a small wire staple 21 which may be shoved through it and against the eye. The curved sides ofthe eye operate to turn the points of the staples as they come against them. The adjacent portion of the sleeve is preferably provided with a reinforcing piece 22. These reinforcing pieces may be made of stiff paper or stout woven tape.

In view of the fact that the up er portions of the sleeves should always hold themselves between the rib and the cover, the openings 11 and 15 will be sufiiciently short to insure that this would take place.

Where. the cover sections 7 are attached together near the crown 3 of the umbrella they are cut so as to produce a projection or nave 23 in the cover adjacent to the crown. In order to produce this effect the adjacent edges of the umbrella sections are out in a curve (see Figure 10). It is not feasible to bend the paper strip 8 readily along a curved line and in order to enable the strip to adapt itself to this general shape we provide it with one or more folds 8 having the general character illustrated in Figure 11. That is to say, the bifurcated or creased strip is buckled into itself so as to form a transverse double fold. By having this fold wider on one side than the other the direction of the strip will be changed to make it conform to the general direction of the attached edges of the sections. See Fig. 10. These folds, however, do not interfere. in any way with the sewing of the stitches 10 on a sewing machine, and have the effect of a reinforcement at this point.
