9 Claims.

This invention relates to umbrellas, and particularly to those intended for use in an emergency, such as when one is caught in a sudden rain storm without an umbrella of usual construction.

An object is to provide an umbrella, the form and construction of which will enable most of the parts employed to be formed from inexpensive materials and easily and quickly assembled into the finished article at a cost of production which is so negligible that the article can be sold for a few cents and thrown away when it has fulfilled the specific purpose for which it is designed.

A further object is to provide an umbrella in which all parts thereof are capable of standardization to thus further simplify the work of handling and assembling same, and in which the parts when assembled will function in a highly satisfactory manner and enable'the cover to be easily and quickly opened when desired.

Another object is to provide an umbrella which, when folded and arranged on sale, will be exceedingly compact, but nevertheless is provided with a cover, the area of which, when open, will render it entirely suitable and effective as la shelter and protecting means for the clothes of the person of the user. Y l

A still further object is to provide novel` and effective means which will function respectively like the runner and notch of an umbrella of more expensive design, said means being such that when the runner element thereof is moved on the stick to a position to raise the cover it will co-act with means on the stick to prevent accidental closing of the cover and co-act with the notch forming element to afford a high measure of lateral stability to the cover and enable it torsatisfactorily withstand the weight of water thereon. v 'Y Another object is to provide an umbrella which, if desired; can be constructed almost entirely of non-metallic parts and be entirely devoid, of springs or like latch devices for holding the cover open. Y

Another important feature of ,the invention resides in the forms, constructions and arrangements of parts employed, enabling use to be made of a very thin, cheap grade of paper for the cover ofVV the umbrella and without fear ofthe cover being accidentally pierced or otherwise injured by the ribs when the cover is closed.

To enable others skilled in the art to fully comprehend the underlying features of the invention that they may embody the same in variousmodifications 'in structure and relation contemplated, drawings depicting a preferred form have been annexed asfa part of this disclosure and in such (o1. 13a-2go) drawings similar reference charactersdenote corresponding parts throughout all the views, of which I Figure 1 is a perspective View of the umbrella showing the cover raised ;V Y

Figure 5 is a horizontal line 5-5 of Figure 2;V y Y f Figure 6 is a perspective view of the runner, and Figure 7 .is a section on line 'I-l of Figure 2. In carrying the invention into practice, use is preferably, but-not necessarily made of a circular cover IIJ of paper or other well known flexible, sheet material of thin, cheap stock, to the central under surface of which is rmly cemented a circular reinforcing disk Il of similar material, and to the under surface of the `disk, I` I is preferably cemented a circularbut somewhat smaller reinforcing disk I2 of stiff material such as cardboard or other vsuitable well known strengthening material. Thelcover I0 maybe water-proofed, if desired.l For practical purposes, ,the cover should be about two and a half feet in diameter when raised to the position shown in Figure 1. The disk I I may be about six inches in diameter and the disk I2 about aninch and a half or two inches. The reason -for describing these specic proportions ofthe parts just referred to vwill be appreciated as the description proceeds. However, it is to be clearly understood that except for particular functional purposes of certain of the parts employed, I do not intend to limit myself to specific proportions of either the parts just namedor others of the parts employed. I particularly suggest that these proportions be followed because, in practice, it ist found 4that proper strength vand durability will ,thereby be given the central portion of the cover to enable it to withstand the strains and stresses imposed Vthereon when the cover is raised while contributing substantial,reinforcement to the cover to prevent it from Vbeing torn or otherwise injured by `the adjacent ends of the ribs of the umbrella when the cover is closed.

The stick I3 may consist of a short stiff strip of wood, liber board, or any other well known, light, tough material of a `cheap grade, the same being of rectangular form in transverse section, as shown in Figures l and 5. The stick isa little the section taken on the more than a foot in length and the free handle end thereof is intended to project slightly from the open end of the cover when the latter is closed, whereby to enable it to be conveniently manipulated when raising the cover. The opposite end of the stick is formed with a substantially, but not necessarily circular tang I4 which is shown as being embraced by friction inducing material I4a such as a strip of adhesive tape, cloth, rubber, cork or the like. While the tang is shown as an integral part of the stick, it may, if desired and for added cheapness of construction be made as a separate element of wood, fiber, cardboard or the like and secured to the stick in any suitable obvious manner so long as it is properly correlated with the parts of the device with which it is intended to coact.

Disposed centrally of the cover and exteriorly thereof is a rigid element I5 of any suitable shape which functions with the stick to take the place of a notch of the kind usually found in umbrellas of more expensive construction. It is of large area relative to the diameter of the cover and extends, as shown, over a substantial portion of the cover and comes wholly within the area described by the aforementioned disk II. In the form of the invention herein illustrated, said element is substantially rectangular and from side to side measures preferably about three inches. This element may be constructed of any Well known thin fiat strip material of a relatively stiff nature so that it will not flex. Such material may consist of compressed fiber and while I have stated that it is rectangular in shape, it can in fact be of any desired configuration. Through the center of the element I5 is driven a nail or other equivalent fastening device which can penetrate the Various plies` of material at the center of the cover and be firmly driven into the upper end of the stick to thus hold the latter operatively attached to said cover. A small portion of waterproof cement is preferably applied between the cover I and element I5 to insure against leakage at this point.

Secured by cement or the like to the underside of the cover are radially disposed linear stiff ribs I'I. Said ribs can be constructed of wood or the like, and each thereof is of rectangular form in cross section, as shown in Figure 7, thus providing flat upper and lower surfaces I 'Ia and I'Ib. The inner ends of the ribs terminate just outside the marginal edge of the disk I2. In Figure 4, it will be noted that the inner ends of the ribs are disposed in an annular series around said marginal edge of the disk I2 to enable them to be freely adjusted angularly when raising and lowering the cover.

Removably mounted on the stick I3 and adapted to slide thereon and turn on the aforementioned tang I4, is an element or runner I8, the same having a central rectangular or other suitably formed slot I9 whose opposite side walls are provided with confronting curved surfaces 20. The surfaces 20 are concentrically related to the tang when the runner element is in cover securing position. The stick I3 freely passes through the slot I9, and when the runner is in the position shown in Figures 1 and 2, the slot is disposed at right angles to the broad fiat sides of the stick at which time, the concentric surfaces 20 co-act with the curved surfaces of the tang to hold the runner element in a fixed position of adjustment relative to the element I5. It will be noted on reference to Figure 5 of the drawing that the tang I4 has a diameter slightly larger than the short transverse section of the stick I3, whereby to prevent the runner from slipping or moving laterally when fully elevated to cover securing position. Upon reference to Figure 2, it will be noted that the length of said tang I4 plus thickness of disk I2 is equal to the combined thickness of the runner I8 and rib I'I, thus providing a tight lost motion preventing means to hold the parts in intended positions of rigid adjustment. The length and width of the slot I 9 in runner I 8 are proportioned to provide a more or less close sliding fit between the Walls thereof and the surfaces of said stick.

Having fully described the essential structural features of the invention, as well as the functional features flowing therefrom, the operation is described as follows:

When the runner element I 8 is turned 90 from the position shown in Figures l and 5, it can freely move downwardly on the stick I3, during which movement the cover can be closed against the sides of the stick. When it is desired to open the cover, the runner element is threaded or passed onto the stick and moved to a position to engage against the under side of the cover and to gradually force the cover to a full open position of adjustment as shown in Figures l, 2, and 3. When the cover is thus opened, the slot I9 in the runner element will coincide with the tang I 4 and by turning the runner 90 the slot in the runner Will occupy a position at right angles to the width of the stick as clearly illustrated in Figure 5. The element is now firmly secured to the stick and the upper surface of the runner will engage fiatwise and very firmly and snugly against the flat faces I'Iby of the ribs I1. The upper fiat faces I'Ia of the ribs will, in like manner be rmly held against the under broad fiat face of the element I5. It is in this manner thatY the cover will be stretched and given the required measure of rigidity and stability to enable it to satisfactorily withstand the Weight of water falling thereon and effectively resist the effect of the wind. I wish particularly to stress the novel construction of the cover of the umbrella; the means employed to reinforce the central portion of the cover, whereby the ribs, when the cover is closed cannot tear said cover; the use of broad width infiexible elements I5 and I8 between the stiff ribs and coacting with each other to very firmly secure the ribs therebetween when the cover is open; the manner of attaching by cementing the ribs I'I to the cover to leave the inner ends of the ribs in annular series formation relative to the long axis of the stick, whereby to provide ample iiexibility to enable the cover to be quickly opened and closed, at the same time, leaving portions of substantial area of the ribs disposed for confinement between the elements I5 and I8. I Wish to further stress the novelty existing in the use of a single fastening device such as the nail, or the like for securing the cover to the stick and for securing the disk I2 firmly against the end of said tang I4, whereby to provide a sealed connection at this point when use is made of a suitable Waterproof cement at and around the parts and the central portion of the cover. Water proof paper can be used in the construction of the parts I0 and I I. The peculiar construction of the tang I4 is also considered a feature of novelty enabling a firm clamping connection to be established between the elements I5 and I8 and assuring that the cover can be held open without the use of spring latch devices or the like.

It will appear obvious from the foregoing that I have provided from the organization of parts disclosed, an umbrella of simple inexpensive construction that will be entirely effective for use as proposed. While I refer to the use of the device as an emergency umbrella, it follows that certain of the novel features employed can be used in co-nnection with sunshades and umbrellas of more expensive design without departing from the spirit of the invention.
