JOHN J. CLARK, OF CHICAGO, ILLINOIS.

UMBRELLA.

Application filed May 26, 1924. Serial No. 715,771.

This invention relates to improvements in umbrellas, and has for its principal object to provide an umbrella which may be cheaply constructed and which may be convene iently folded to form a small parcel when not in use.

Further objects relate to various features of arrangement and construction of parts, which will become apparent from a consid- 1 eration of the following specification and the accompanying drawings, wherein Fig. 1 is a plan view of the lower side of the top or shelter portion of the umbrella.

Fig. 2 is a sectional view taken on line 22, Fig. 1.

Fig. 3 is a view similar to Fig. 1 showing a modification of my invention.

Fig. 4 is a further modification of my. invention.

Similar reference characters are used throughout to indicate like elements.

is the top or shelter portion of my umbrella which may be made of any suitable waterproof material, either cloth or paper which may be treated to make the same impervious to moisture.

Radially arranged on the underside of top 10 are provided a plurality of supporting ribs 11 of light material, such as thin strips of wood. Ribs 11 are secured by means of pieces of tape 12 to top 10 adjacent the center thereof and by additional transverse strips of tape 13 and 14, as shown. The strips 13 and 14 are preferably not attached to ribs 11 thereby permitting radial movement of said ribs in closing or opening the umbrella. An opening is provided in the center of the top through which a handle 15 may be inserted. A pair of disks or plates 16 and 17 which may be of light material, such as wood or stifi' fibre board, are disposed, one on either side of the top, for rigidly supporting the same, a pin 18, or the like, passing through 45 a small opening in the top of handle 15, preventing the upper disk 16 from being pushed from the top of the handle- A sleeve or slide member 19 supports the lower disk 17 firmly against the lower surface of top 10 and the ends of the supporting ribs 11, said member 19 being retained in clamping position by means of the spring latch 20. The umbrella may be lowered by depressing latch 20, permitting sleeve 19 and disk 17 to slide downwardly on handle 15. The

the other, or be otherwise constructed in such manner that the same may be carried conveniently with the folded umbrella, as will be clear. The slide member 19 may be formed integrally with disk 17 or be secured thereto, or it may be omitted, if desirable, the latch 20, in such case, directly coacting with disk 17 to secure the same inoperative position.

The form shown in Fig. 3 is similar to that just described, except that the inner ends of the supporting ribs 11 are secured to a small apertured disk 23 by means of strips of tape 12, or the like. The top of the umbrella shown in Fig. 3 will be supported between disks, similar to disks 16 and 17, shown in Fig. 2 and may be folded along similar creased lines 21 as in Fig. 1.

In Fig. 4 is shown a modification comprising a top and reinforcing ribs secured to a central apertured disk 23, as shown in Fig. 3 for instance, the upper disk 16 being permanently secured to handle'15 as by glue. A follower 19 having a supporting flange 19 which functions similarly to disk 17 of the previous modifications, is adapted to be held in firm contact with ribs 11 by latch 20, as shown. This type of umbrella may be raised or lowered similarly to umbrellas in common use at the present time and may be made so inexpensively that they can be used. for an emergency and thrown away.

Although I have shown certain forms and modifications for the purpose of illustration, it will be obvious that further forms may be devised which do not depart from the spirit of my invention, and I do not therefore wish to be restricted to the specific embodiments of my invention herein described except where limitations thereto appear in the appended claims.

What I claim is r 1. An umbrella comprising a top of relatively stiff material scored to fold on predetermined lines, a plurality of reinforcing ribs attached to said top, each rib being centrally disposed between two adjacent lines, a handle for said top, and a pair of discs on said handle, one disposed on each side of said top, said discs serving-to clamp the inner ends=of said reinforcing ribs there'- between' to hold the same in top; supporting relation. p

2. An umbrella comprisinglatop of relatively stifl material scored to fold'on pre' determined lines, a plurality of reinforcing;

ribs for supporting the same, each rib being centrally disposed between; two adjacent lines, a handle for said top, and a pair of discs on said'h andleyone' disposed one' each side of'said top, said "discs servinglto :clamp, the inner end-s of'said reinforcing iribsthere-r between to hold the same in top supporting relation.

3.-An emergencyumbrella comprising a top adapted to fold on predetermined radial lines, a plurality of relatively flat ribs for supporting the top, each rib being disposed between two of said lines-and being secured atom of itsv flat sides to the top, at spaced points along its length, said ribs being unconnected one to the other and terminating at theirinner' endsshort of the center of the top,--,a readily removable handle passing through the center of the top, and a pair of disc-likeqmemberson the handle, one disposed on each side of the top for clamping thfli'lIlllfiIf'QIl'ClS of the ribs between: the same forrholding Jthe-top in operative post tion; one of said- 'disomem'bers being ,slidable:

on the handle for permitting the ribs be moved "in'a direction toward the handle in lowering the umbrella.

In testimony whereof, .I have subscribed my name. 7 V
