UMBRELLA. v

Specification of Letters Patent.

Patented Mar. 18, 1919.

' Application filed May 29, 1914. Serial No. 841,749.

To all whom it may concern:

Be it known that I, FRANK W. HOWARD, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Umbrellas, of which the following is a specification.

This invention relates to umbrellas, and a principal object of the invention is to produce an umbrella which is of very simple construction and very inexpensive, the general purpose being to enable such umbrellas to be available in an emergency, as for instance where a person is caught'unexepectedly in the rain. While the umbrella may be used again it can be sold for such a low price that even if it could be used but once it would serve its purpose. Hence the general object of the construction is to produce such an arrangement as will enable the parts to be very cheaply constructed and very readily assembled to form the complete umbrella.

Further objects of the invention will appear hereinafter.

In the drawing which fully illustrates the preferred embodiment of my invention,

Figure 1 is a vertical section through the umbrella in its open position.

Fig. 2 is a side elevation showing the umbrella closed. 4

Fig. 3 is a cross section through the stick of the umbrella at the crown looking upwardly, and showing the middle portion of the cover broken away.

Fig. 4 is a side elevation showing a por tion of the stick at the position of the run ner when the umbrella is raised.

Fig. 5 is a cross section taken through the rib and showing the cover and the preferred means for attaching the cover to the ribs.

Fig. 6 is a fragmentary view indicating means for reinforcing the edge of the cover and for attaching same to the rib.

Fig. 7 is a side elevation showing the construction of the runner and means for securing the stretchers thereto.

Fig. 8 is a side elevation illustrating a portion of the runner, partly in section.

Fig. 9 is a cross section similar to Fig. 5, but showing a special construction for con necting the over-lapping edges of the cover showing a different kind of reinforcing member for the edge of the cover.

Referrmg more particularly to the parts,

15 represents a stick which is preferably of very inexpensive wood, one end of which may be provlded with a knob 15 to form a handle. On the outer end of this stick I force a crown 16, which preferably is in the form of a relatlvely large wooden spool or. sleeve having a bore which fits tight on the stick.

This crown is preferably in the form of a sleeve provided with an enlarged circumferential socket groove o'r recess 17. The ribs 19 of the umbrella extend radially from the crown in the usual manner but each rib is preferably provided with an integral helical coil 20 the side of which rests in the bottom of the groove 17 so that each coil rocks in the socket 17 and each coil acts as a pivot for its rib when the umbrella frame is raised or lowered. I provide means for retaining these coils in the socket, which is preferably in the form of a ring 18 of wire which passes successively through the coils and holds them against the side of the crown. I also provide means for maintaining the ribs equidistant circumferentially around the stick. To accomplish this I prefer simply to make each coil 20 sufficiently long so that when applied to the groove or socket it will assume an arcuate form andextend along the groove, its outer end engaging an adjacent rib. In this way the coils themselves act as distance pieces to maintain the ribs substantially equidistant from each other.

The diameter of the coils 20 is such that they fit in the recess or groove 17 and retain the ribs on the crown. The umbrella cover 21 is preferably formed of a very inexpensive waterproof paper, the said cover being preferably composed of sectors or segments 22 having overlapping edges 23. These overlapping edges preferably are located at the ribs, and I prefer to secure them to the ribs by means of fastening devices 24 preferably formed of wire and .havingtwo points 25 which extend through the cover and form hooks 26 passing around the rib in opposite directions.

In order to make this connection more'secure I prefer to provide a reinforcing piece 27 of stout paper or similar material on the outer; side, and through this the fastener passes.

Instead of simply overlapping-the edges as shown in Fig. 5, I may form them with a. double overlap edge'QS such as indicated in Fig. 9. This makes a very secure connection, and the edge acts as its own reinforcement when attached by fastening'devices to the rib 19. t

The runner29 is preferably in the form of a sleeve and comprises a wire bent to form a relatively large ring 30, which is formed integral .with a sleeve in the form of a coil 31, said coil 31 tending to assume a slightly smaller diameter than the stick 15 at the point where the runner lies when the um b-rella has been opened. The end of the coil forms an extension 32, and oneend of the ring 30 has an opposite extension 33 arrangedso that when extensions 32 and 33 are pressed toward each other the coil 31 will :be slightly expanded This mode of operation is facilitated by the fact that a shank 34 is formed at the upper end of the coil 31, and this shank abuts against an opposite shank 35 'connectingthe extension 33 with the ring 30. a

The stretchers 36 are preferably formed of stout wire and attached to the ribs at the usual point by means of eyes 37 formed integrally in the ribs. These stretchers have eyes 38 at their inner ends passing around ring 30. In order to hold the stretchers 36 spaced equidistant on the ring 30 I prefer to provide a collar. This collar may'have the form indicated in Fig. 7, or that indicated in Fig, 10. As illustrated in Figs. 7 and 8 the collar is simply in the form of a flat band bent'into a ring 39 and having openings 40 through which the eyes 38 are attached. The ends of the ring 39 abut against the shanks 34 and 35. Instead of forming the collar as shown I may form it as indicated in Figs. 10 and 11. In this case the collar is formed from a blank orv plate 41 of considerable width and having transverse equidistant slots 42 so that the blank can be folded" on its longitudinal axis about the ring 30,'the edges being brought together so that the collar is secured to the ring, but leaving a plurality of gaps 43 around the ring equidistant from each other formed by the slots 42, and at which the eyes of the stretchers may be attached.

In order to enable the runner to stay in a position to hold the umbrella open I prefer to provide the stick '15 with a slight enlargement 44 at the proper point. It should be understood that the coil 31 is resilient and is sleeve, but it need not be of greatly larger. diameter than thestick, and it is preferably produced by causing a slight swelhng at this point, which may be efiected by driving laterally into the stick a pin 45. This pin has a slight wedging efiect, which expands. the

This enlargement 44 is of stick, and at the same time the head of-the pin is left projecting so as to form astop to prevent the runners from being forced past the enlcrgement. 1

Referring again tovthecover 21in order to facilitate the attachment .of. the Upper portion of the cover towthe crown Iprefer V '1 to formthe cover with a central opening 46 adjacent the crown, but this opening is closed by means of-a center 47, preferably formed of a material. such as fabric, which may be conveniently attached to the stick by means a of a ferrule 48 and which extends over the upper edge of thecover around the opening and is securedto the cover by an adhesive preferably waterproof. The usefofrfabric at this point materially increases the efficiency of the umbrella, but does not greatly increase the cost, as it would if theentire cover was formed of this material. It also enables the umbrella to roll, up nea-tlyaand without tending to tear the cover nea'rthe In order to strengthen the. umbrella around the edges of the cover, and in, order to facilitate the attachment of the cover to the ribs atthis point, I prefer to provide the edge of the cover with a. reinforcement or bindlng which may be in the form of-a cord or band. As illustrated in Fig. 6 this reinforcement is in the form of. a 'cord 49, Y which passes contlnuouslyaround. the cover,

said cover being folded around the cord. At the points where the ribs 19 lie I'prefer to provide eyelets 50 around the outer'side of which the cord 49 passes, and these eyelets are preferably placed at the overlapping V edges 23 of the segi'nents'of the cover. I

prefer to reinforce the edge of the cover by folded clips 50*, folded edge 50 being applied to the edge of the cover so that the eyelet passes through both'fiaps ofthe clip as well as the cover. 7

Instead of using the cord 49 I may employ a reinforcement at this point in the form of a tape 51'illustrated in Fig. 12, and

the eyelet 52 is then applied through the tape and through the overlapping edges 23.

In either case I prefer to attach the cover to the ribs by means of the eyelets and by bending the outer extremity of the rib outwardly and upwardly so as to form an eye 53 engaging the eyelet. This construction results in placing the eyelet in the Plane of the adjacent portion of the cover and this reduces the strain on the cover in a way that is particularly desirable in a cover of frangi ble material such as paper.

The reinforcement pieces 27 may be placed inside the cover and between the cover and the rib.

When the umbrella is rolled up folds or creases 55 are formed in the paper cover. These creases weaken the cover, but thetape 51 prevents any tendency of the material to tear by relieving it of strain when the umbrella is open.

In order to hold the umbrella in its folded condition, as shown in F i 2, I prefer to provide a fastener consisting simply of a paper button 54 having a cord 55. When the umbrella is folded and rolled up this cord is simply passed taut around the umbrella and several turns of its end are taken around the button. By using this cord there is no strain on the parts of the umbrella, as the cord can be made tight or loose asdesired.

It is understood that the embodiment of the invention described above is only one of the many forms or embodiments the invention may take, and I do not wish to be limited in the practice of the invention, nor in my claims, to the particular embodiment set forth.
