UMBRELLA.

Applieatien filed December 16, 1927. Serial No. 240,339.

This invention relates to improvements in umbrellas.

One of the objects of this invention is to produce an umbrella which will maintain equilibrium irrespective of the varying air currents pressing against the inner and outer surfaces of the foldable covered frame when it is in unfolded position, and to prevent the air current from compressing or con- (lensing within the inner surface of the foldable covered frame.

Another object of the invention is to provide a construction of umbrella which may be more readily drained and in which the lower portion of the umbrella which frequently rots because of the lodginent of water therein, will be fully drained and dried by aeration when the same is folded.

Another object of the invention is to provide an umbrella with a centrally-located aperture which will be automatically opened by the closing movement of the umbrella and closed by the opening movement thereof and which aperture, when the umbrella is in folded position, will communicate with the interior thereof to furnish drainage and aeration, and when the umbrella is in open posi tion, will be covered and maintained in covered position to keep out rain.

Another object of the invention is to pro vide an umbrella with a centrally-located air vent and shield therefor which will add to the attractiveness of the umbrella without ma terially adding to the weight or cost of manufacturing.

Still another object of the invention is to provide an umbrella having an aperture adapted to be automatically opened by the closing movement of the umbrella and to be shielded by the opening movement thereof with a shield provided with air channels adapted to be simultaneously opened by the opening movement of the umbrella.

WVith these and other objects in view, the invention comprises the combination of members and arrangement of parts so combined as to coact and cooperate with each other in the performance of the functions and the accomplishment of the results herein contemplated, and comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which Fig. 1 is a vertical section taken at one side of the rod of an umbrella embodying my in vention;

Fig. 8 is a vertical section similar to Fig. 2 of a modified form of my invention;

Fig. 9 is a section similar to Fig. 8, illustrating in folded position, the modified form of umbrella shown in Fig. 8

Fi 10 is a section on the line 101O of Fig. 8, looking in the direction of the arrow; and

Fig. 11 is a perspective view of a guiding element employed in my invention.

Referring now to these drawings, which il lustrate a preferred embodiment of my invention, 1 is the handle of an umbrella, 2 the rod, 8 the skeleton or frame comprising the cover-stretching ribs 3 and the radial arms 3" pivoted at one end to the ribs 3 and at the other end to a ferrule 3" slid-ably mounted on the rod 2, the ribs 3 being pivoted at their innor ends at 4 at a fixed point on the rod 2 and also being suitably connected at various points to a cover 5. In the claims herewith appended, I have termed the conventional umbrella parts hereinabove described as a fold able covered frame and will now proceed to point out my improvements thereto.

The inner ends 4 of the ribs 3 are pivoted on ears 6 preferably spaced from the rod 2 and formed, as shown, at the inner end of a guiding element 7. The other end ofsaid guiding element preferably extends above the foldable covered frame of the umbrella and is provided around the circumference with .a series of longitudinal slots or vent-apertures 7 separated by bars 8 which are connected at one end with a collar 9 with which the ears 6 are integrally formed and at the opposite end with an ornamental base piece 10 having a centrally-located -socket 11 within which the end of the rod 2 seats and to which it is fastened by the pin 10, said element 7, which is shown in perspective in Fig. 11, being also held in spaced relationship to the rod 2 by the mounting collar 12 to which it is connected by suitable pins 13 and which mounting collar is connected to the rod 2 by a pin 141.

lhe provision of such rib-pivoting and guiding element 7 spaced, as aforesaid, from the rod 2, provides an opening 19 preferably annular in conformation, surrounding the axis of the rod 2 and communicating from the interior of the umbrella through the slot 7 to the exterior thereof. An opening is thus formed which will vent the space heneath the cover and thus permit the escape of air currents coming under said umbrella so to release such excessive pressure of air currents as would otherwise act againstthe under side of the cover to turn it inside out. This venting and release of the force of the air currents will obviously enable a person carrying the umbrella to maintain the same in open, upright position without the unbalancing pressures common to unvented covers, and, therefore, with much less effort than can be done without the release of such excessive air currents.

While the means so far described would l ase all excess air pressure from the inter of the un'ibrella, it is apparent that unless the venting apertures be suitably shielded, rain would enter therethrough and in the embodiment shown, would pass down on the rod to the handle of the umbrella and hand of the user. I, therefore, provide means for B 'eldin the venting aperture from the adn'nssion of rain while allowing such escape of air, and I have shown two embodiments of my invention including different means for s0 applying a shield. In each embodiment, I preferably employ shield-operating means which will be operative, upon the opening of the umbrella, to shield the venting aperture and, upon the closing of the umbrella, to open the venting aperture so as to provide an effective draining of the interior of the umbrella cover and of the shield and also to provide a passage for the ventilation or admission of air into the folds of the umbrella when the same is in closed position, thus insuring a speedier and more complete drying of the lower end of the cover and preventing rusting of the ribs and decay or rotting of the fabric thereof.

' In the preferred embodiment of my invention, shown in Figs. 1 to 7 and 11, I provide a shield 15 connected at its outer periphery with the main cover 5 of the umbrella. in such manner as to provide between each of the ribs, a radial air channel communicating with the vent-aperture 19, and in said preferred embodiment, I preferably provide beneath the shield 15 an enlarged vent-aperture 29 by connecting the annular edge 17 of the cover to the ribs at a point somewhat distant from the pivotal connection thereof with the ears 6.

In the said preferred embodiment of my invention, I provide means for automatically shielding the vent-apertures 7 in the guiding element and simultaneously raising the axial or central portion 15 of the shield 15 to tighten or stretch the same so as to form or produce on the outer surface of the foldable covered frame a series of effective radial air channels 18 communicating through the apertures 7 and through the openings 19 and 20 to the interior of the foldable covered frame.

l Vhile the said vent- apertures 7 and 19 or 20 when covered by the shield 15 will substantially release the excess air pressure from the interior of the umbrella toward the exterior without admitting rain, a wet umbrella when folded might cause moisture to run from the exterior surface of the cover 5, through the channels 18 of the shield into the interior of the umbrella through the apcrtures 19 and 20 and collect upon the rod 2 near the point of auction of the ribs. To prevent such a collection of moisture, I employ the vent-aperture 19 and the slots 7 as a drainage and aeration means and I provide means to unshield the external parts of the said slots '2" automatically upon the folding movement of the umbrella, and to shield the said slots automatically upon the opening movement of the umbrella.

In said preferred embodiment, the auton'iatic shielding and unshielding of the slots 7 is produced by the same means and simultaneously with the raising and with the lowering of the shield 15. As is shown in Figs. 1 to 7, I have provided a series of links 21 pivoted at their outer ends 21 to the ribs 3 and at the opposite ends 21 pivoted on lugs or ears 22 arried by a ferrule 22 slidable up and down on the bars 8 of the guiding memher 7. As illustrated, the central or axial portion 15" of the shield 15 is mounted be tween a horizontal flange 22 and the upper pivoted ends 21 of the links 21.

It will be apparent that, upon the opening of the umbrella in the usual way, the links 21 will cause the ferrule 22 and the annular central or axial portion of the shield 15 to be raised so as to shield the air-vent openings through the slots or vent-openings 7 and annular space 19 and at the same time by stretching the shield will cause a more effective opening of the horizontally-extending radial air channels 18 communicating with such vent-openings.

In Figs. 8 and 9, I have shown another means for automatically raising a shield to close the vent-openings to the interior of the umbrella. In this form I preferably carry the inner end 17 of the main cover into a position close to the guiding element 7 so as to leave only a single vent-opening 19 communicating with the venting openings 01 slots 7 of a guiding member 7 and I preferably provide a shield 15 which may be substantially similar to the shield 15, except that it may be smaller and has a longer connection at its outer end with the main cover of the umbrella. In this embodiment of my invention, a sliding ferrule 22* is normally and automatically forced to its upper vent-closing position by the action of a spring 28, having one end pressing against an interior spider 15 integrally con nected with said ferrule 22* and the other end abutting in relatively stationary or fixed posi tion against the fastening collar 12 of the element 7, said ferrule carrying the annular central portion 15 of the shield 15 upwardly when the umbrella is opened. lVhen, however, the umbrella is closed, the ferrule, to gether with said central portion 15 will be drawn downwardly along the guide element against the pressure of the spring 23 to uncover the vent-openings 7 communicating with the annular vent channel 19, thus enabling free passage of air and moisture through said openings while the umbrella is in closed position.
