Specification of Letters Patent.

Patented Mar. 11, 1913.-

Applieation filed October 15, 1912. Serial No. 725,882.

To all whom, it may concem:

lie it known that I, Lnns LARSEN, a citizen of the United States of America, residing at Goldfield, in the county of Esmeralda and ,b't-ate of Nevada, have invented new and useful Improvements in Folding Umbrellas, of which the following is a specification.

This invention relates to improvements in umbrellas and has particular application-to folding umbrellas.

In carrying outthe presentinvention, it is my purpose to provide a folding umbrella which will be constructed in such manner that in the movement'of therunner to separate the ribs under-the action of the separators, an initial movement will be imparted to the ribs so as to enablethe umbrella to be opened-readily and easily.

It is also my purpose to provide a folding umbrella which will embrace the desired features of simplicity, etliciency-and durability coupled with cheapnessv of cost" in manufactureand marketin and which may bev quicklyand easily fol ed into a small compact package, thereby enabling the umbrella to bestored in a small space when not in use.

- through one of the runners showing the connect-ions between the same and the braces. F ig. 4 is a perspective view of a detail of th e invention. F ig. 5 is a fragmentary sectional view through the umbrella stick and the notch secured thereon. ,Fig. 6 is a cross sectional view through the stick showing the slidable notch in top plain Fig. 7 is a fragmentary plan view of one of the ribs showing the connection between the sections thereof and'the spreader.

Referring now to ..,the accompanying drawings in detail, the numeral 1 indicates the stick of the umbrellawhich is preferably conposed oi two detachably connected sections 2, 2, the stick 1 being equipped at one end with a suitable form of handle-'3, while the opposite end is provided with a wear cap 4 as usual. Rigidly secured to the stick 1 an appropriate distance from the free end thereof is a notch 5 formed, in the present instance, of a disk 6 provided with i a number of peripheral slots 7 suitabtli spaced apart, the disk being rovided wi a peripheral groove 8 to receive the retaining wire 9.

The ribs of the umbrella are indicated at 10 and each, in the present instance is composed of two sections 11, 12 having their meeting ends overlapped and pivotally connected to each other as by bolts or pivot pins 13. interposed between the overlapping ends of the sections 11, 12 of each rib is a sustaining plate 14 formed, in the present instance, of a single sheet of metal having the opposite ends thereof extended downwardly and bent-laterally in relatively opposite directions to provide lugs; 15, as-

clearly shown in Fig. 4 of the drawin These lugs 15 aredesigne'd to engage t e .lower edges of the respective sections 11, 12

when the umbrella is 111 open position, thus collapsing of the sections is avoided. The

free end of the scction'12 of each 'rib is 'disposed withinone of the slots 7- of the notch and is provided with an apcrturethroug'h which is passed a retainin wi're9. Thus, a

pivotal connection'is cstab ished between the ribs and the notch. f

The Spreaders of the umbrella are-indicated at 16 and each, in the present instance, comprises two sections 17, 18 having their meeting ends overlapped and pivotally connected to each other, while a sustainin plate similar in construction to the plate 1% hereinbefore described in' connection with ping ends of the sections of the spreaders to prevent undue relative movementof such sections in the opening "of the umbrella. One of the sections of each spreader 16, as the section 17, has the free end thereof 'piv-- otally connected to the section 12 of the respective rib through the medium of a pivot plate 19 suitably secured to the'res'pective rib section at the rear of the pivotal connection between the sections ofsuch rib, the

free extremity of the section 17'of eachspreader being beveled as at 20 to engage the section 11 of the respective rib, so as to revent the sections 11 of the ribs from fol ing 4 onto the sections 12 thereof in the open posithe ribs, is interposed between the overlap.

lot

U connection with the accompanying tion of the umbrellar The free ends of the sections 18 of the Spreaders are each disposed within a slot 21 of a second notch 22 suitably secured to the umbrella stick and spaced apart from the first notch, a retainingwire 23 encircling the second notch and is passed through the free ends of the respective sections of the spreaders to establlSll a, pivotal connection between said sections and the notch.

Slidably disposed upon the stick 1 between the notches thereon is a runner 24 composed in the present instance of a disk 25 having slots 26 formed in the periphery thereof and suitably spaced apart, a retaining wire 27 encircling the disk 25 ofthe said runner and overlying the peripheral slots therein. Pivot-ally connected to one of the sections of each spreader, as the section 18, by means of a pivot pin or the like 28 is one end of a brace 29 and'each brace has the opposite end thereof formed with an elongated slot 30 and disposed within one of the peripheral slots 26 in the disk 25 of the runner 24, the slots 30 in the said braces receiving the retaining wire 27 whereby a loose connection is established between said runner and braces, for a purpose which. will presently appear. A second runner 31 is also slidably disposed upon the stick 1 of the umbrella beyond the notch 22 thereon and is connected in any suitable manner, as by rods 32, 32 with the first-mentioned runner, whereby in the movement of the runner 21, motion may be imparted to the runner 24. Any suitable form of catch 33 may be employed to hold the second runner againstaccidental movement when the parts of the umbrella are in open position.

In order that an initial movement. may be imparted to the ribs of the umbrella, when it is desired to open the same, so that such umbrella may be opened quickly and easily, 1 mount upon one edge of the sections 12 of each rib, an inwardly extending lug 34;, W'lll"li, when in the closed position of the um? lies in the path of movement of the runner 24. From this construction, it will be seen that, in the initial movement the runner 2a, under the action of the second or mani ulating runner 31, the lugs 34 will be acte upon bythe first-mentioned runner and so impart an initial movement to the "Fibs previous to the latter being acted upon by the braces and Spreaders.

- A' 'suitable form of cover 35 is carried by the: ribs of the umbrella, as usual.

From the foregoing description tak n in v awuction mode of operation of my impro d un will be readily understood. Arsumi' the parts to be in closed position as Slit m in Fig. 2, and it is desired to open the same as shown in Fig. l, the sections 11 of the ribs are swung about ings, the coa their pivotal connections with the sections movement to the runner24, through the mei dium of the connecting rods 32, 32. In the downward movement of the runner 24:, the retaining wire 27 carried by such runner passes from one end of the sl0ts'30 in the respective ends of the braces 29., to the opposite ends of such slots, while the runner proper engages the lugs 34 on the ribs to move the latter outwardly. In the com tinned movement of the runner 24, the braces 29 are; acted upon, incident to the retaining wire reaching the end of the slot 30 inqeach brace, and the braces, being pivotally-con- 'nected to the sections 18 of the Spreaders 16 act upon the .latter to swing the sections of the spreaders to open position, thereby' swinging the ribs to a position to open the umbrella.

It will be seen that I have provided a folding umbrella wherein the sections of the spreader-s and ribs may be folded one against the other in the folded position of the umbrella, and in which the ribs and Spreaders are securely held in operative relation when the umbrella is open.

\Vhile I have herein shown and described one preferred form of my invention by way of illustration, I-wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without'departing from the spirit of the invention.

I claim:

l. A folding umbrella including a stick, sectional ribs and spreaders, a runner on said stick, connections between said runner and spreaders, and lugs carried by said ribs and disposed in the path of movement of said runner whereby an initial movement may be imparted to the ribs previous to the operation of the Spreaders.

2. A folding umbrella including a stick, sectional ribs and spreaders, a runner on said stick, loose connections between said runner and Spreaders, and means carried by each rib anddisposed inthe path of movement of said runner whereby an initial movement may be imparted to the ribs previ one to the operation of the spreaders.

3. In a folding umbrella, a stick, a notch secured to said stick adjacent to one end thereof, ribs each connected at one end tov said notch and comprising a number of sec tions, a second notch on said stick spaced apart from the tirstmentioned notch, spread as each pivoted at one end to said second notch and at the opposite end. to one of said ribs and composed of a number of sections, a runner on said stick between the notches thereon, braces each pivotally connected to one of said Spreaders, a loose connection between the free end of each brace and said runner, means carried by said ribs and dis-.

ner on said stick, and connectiilns between 10 said second runner and the firs nner.

In testimon whereofi I aflix my signature in presence 0 two \fltnesses.
