I This invention relates to improvements in .so called emergency umbrellaso'f the sort folded fromwaterproof paper and intended to beretailed'at a very 'low price at news sta'nds,-, cigar stores and other convenient.

points where a person caught in a sudden v shower may avail hi'mselfof such a protective covering and then discard'it when the emergency has passed. 7' f Umbrellasof the emergency type have already been'devised, but they have all been open to the same objection, that they were costly to manufacture and consequently could not be offeredat a price which would make the proposition attractive as an emergency article; It might be mentioned that the prohibitive costs of'the umbrellas heretofore manufactured were due largelyfto the great number of parts constituting each article,.each part taking its toll in material and labor, in the course of both manufacture and assembly.

Withthe foregoing in mind it is thepurpose of the present invention to provide an emergency umbrella which will consist of the minimum number of parts, and which, while it will be self sustaining, at the same time will besuflieiently durable to withstand the elements, I accomplish this purpose by means of the construction and combination of parts described in detail in the following 7 specification and [claims and illustratively exemplified in the accompanying drawings,

in which, Figure 1 1s a plan View offmy' mproved emergency umbrella shown in 'open pos tion; F gure 21s a substantially transverse sectlonal view of the same taken; on

' lines 2-2 of Figure 1 ,Figure 3 is a plan view of one end of the scored blank from which the cover is folded (Figure 4 is aside view of the blank in'folded position and the connecting meansshownin section, Figure 5 1s an enlarged sectional vview of the cover. connecting means and stick: Figure 6 is a plan view of the same, and Figure 71s a modified embodiment of connecting means and adjacent portion of the cover.

Referring to the drawings, the three elements of the invention are designated gen erally as follows, A denotes the papercovering, B, the connecting means and Ctthe 5 stick.

which-is dividedinto a number of substan- 'tially rectangular-1y shapedfareas 11 by a plurality of equally spaced, scored lines 12 disposed transverselyjof thestrip 10, the materialb'eing folded along the-lines 12 so as to form. a plurality of plaits 13,, which present av hill and dale appearance when the umbrella is in open position as shown in Figures 1 and 2 particularly; The mate rial of thestrip 10, at what-becomesvthe periphery of the covering A, is reinforced by scored lines 14 which are disposed at an angle to the lines 12 and, adjacent end of the blank, thelines- 14 being further disposed alternately so that alternate lines 12 bisectjthe'a pex ofatriangulararea 15 spanning'two sides of apl'ait 13, as illustratively exemplified, in, Figure 3., When the material is in foldedposition as shown in Fig ure 4, the triangular area or gusset 15 folds on itself along. the line'12 and is disposed between two plaits 1 3, thereby leaving the outer end'at an angle to the longitudinal axisjof the plaitsi When the coveringuis material at its'inner end "to which the connecting meansB maybe attached and carried. To facilitate the installation 'of'con necting'means'B, and to give a slight conical shape to the open'covering, the inner end of each plait 13 is cut at'a slight angle in the direction of the score line 1 1 at the opposite or outer end, so that when'the covering is collapsed, as shown 'in Figu're' 4,'the inner ends; will all be parallel and'in superimposed position; A T-shaped slot, 16 is punched through" the layers of' plaits, the cross portion being disposed'parallel toand spaced short of the end of the material while the stemfportion opens out of theend. The

efiectproduced by the slot 16is clearly illusof the end ridge and a suitable fastening means 17 used to fix theconnectiona Referring now to the connecting means B,

the latter comprises a hub or short length of tubing 17 preferably of cardboard which has its ends inserted through the stem portion of the slot 16 into the cross portion, as illustrated particularly in Figure 4, This a. arrangement brings the tabs 16 of material,

on opposite sides of the stem portions of the slots 16, within the cylinder or tube 17, permitting the latter to act as a guide during the opening operation of the cover, which naturally unfolds about the tube as an axis.

With reference to Figure 6, it will be clear that the said tabs 16 arrangethemselves in irislike formation about the inner wall of the tube 17, so as to enable the stick C to be inserted therebetween.

The stick G is simply a straight lengthof full round material, preferably wood or cardboard tubing having a slightly reduced end 18 which is adapted to be inserted into the tubing 17 between the inner ends of-the plaits when the covering is opened for use. It has been found that the end 18 of the stick is firmly gripped by the material at the opening so as to enable the umbrella to withstand considerable strain Without its pulling off of the stick or handle.

In 'the modification of the connecting means illustratively exemplified in Figure 7 the ends of the plaits 13 are merely provided with straight slots 18 parallel to and spaced short of the inclined inner edges, the latter being inserted into the interior of the tube 19 through a longitudinal slot 20 disposed throughout the length of its wall.

When the invention is arranged for sale the cover A is a flat proposition carrying the connecting means B atone end, as shown in Figure 4;. The cover A is then placed in an envelope just large enough to accommodate it and the stick C which is of a length equal to the length of covering when folded.

To erect the umbrella, the folded cover material '10 is swung about the tubing 17 until the end plait 13 is arranged over the ridge at the opposite end whereupon a fastener is inserted. The result is a large circular cone, comprising a plurality of radially disposed ribbed folds forming drainage spaces running to the periphery of the covering and of substantially decreasing depth as they approach the said periphery. The reduced end 18 of the stick C is then inserted through the tube 17 from underneath and firmly gripped by the tabs 16" disposed within the tube.

guide means for one side of the strip about which means the material is rotatably unfolded to open position, and a stick removably inserted in said means. I

3. An umbrella having a cover comprising a plaited strip of material slotted at spaced intervals along one longitudinal edge, a'cyhndrical member pro ecting through sald slots about which member the cover isrotats ably unfolded to openposition, and a stick removably inserted in said member. a

4. An umbrella having a cover folded from a blank comprising a straight strip of i material provided with substantially parallel spaced score lines disposed transversely of the length ofthe blank, the spaces between the score lines being provided with a T-shaped slot at the end forming the center I of the cover, av tubular connection and guide projecting through said slots about which guide the plaits are unfolded in a rotary dircction to form a circular device, and a stick insertable lnto said tubular connection, the

portion of the cover material beyond the said slots being wedged between the stick and the interior wall of thetubular connection.

5. An umbrella comprising a body portion having a series of radially ridged portions forming gutter like. drainage spaces therebe-- tween, the ridges in service being contracted adjacent the center ofsaid body portion and progressivelyexpanded toward the periphery thereof, a guide memberinsertable in said radial ridged portions and about which the latter is unfolded in rotary direction. to open position, and a stick insertable in said member. r

6. An umbrella having a cover portion folded from a blank of straight material which, is scored along spaced parallel lines disposed transverselyof the blank and angularly arranged scored lines along one side of the blank, alternate parallel scored lines bisecting the apicesof the angular lines,

whereby when the cover is unfolded'f-in a circular path there is a series of radially rigid. portions forming gutter like drainage spaces and a similar number of gussets at the periphery ofthe ridges, each space between said parallel scored lines being cut off at an angle'at the side opposite the angular scored lines and provided with T-shaped slots adjacent said ends cut at an angle, a

tubular connecting guide projecting through said slots, about which guide the radially ridged portions unfold in arotary direction,

and a stick 'insertable in said tubular piece and against the material of the cover beyond the said slots.

7. An umbrella having'a cover creased to at an angle to both the transverse and Iangitudinal axes thereof, a tubular hub projecting through said slots, about which guide '10 Q the plaits unfold in a rotary direction to form a cone shaped covering.

In testimony whereof I aifix my signature.
