Specification of Letters Patent.

Patented Sept. 2, 1913..

Application filed December 5, 1912. Serial No. 735,131.

To add who m, it may concern lie it known that I, Inn ll. LONG, a citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented certain new and useful I1nprovements in Folding Umbrellas; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in folding umbrellas.

One object of the invention is to provide a folding umbrella having an improved construction and arrangement of telescoping ribs.

Another object is to provide a folding umbrella which will be simple, strong, durable and inexpensive in construction, reliable in use and which may be quickly and easily folded and unfolded.

With these and other objects in view the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accon'ipanying drawings: Figure 1 is a central vertical section of my umbrella with the parts arranged in position and opened for use; Fig. 2 is a side view partly in section showing the position of the parts when the umbrella is closed; Fig. 3 is a similar view showing the position of the parts when the umbrella is closed and folded and the sections of the handle disconnected; Fig. l is an enlarged longiti'ldinal sectional view through the outer end of one of the inner members of the ribs and the adjacent end of one of the braces illustrating the outer member of the rib in a projected or operative position; Fig. 5 is a cross sectional view through the upper portion of the umbrella stall or handle taken on the line o1"? Fig. l and looking upwardly; Fig. 6 is a similar view taken on the line (5-6 oi Fig. 1 looking downwardly; Fig. 7 is a similar view taken on the line 77 of Fig. 1; Fig. 8 is a detail perspective view of one of the braces; Fig. 9 is a top plan of one of the inner tubular members of the ribs showing more particularly the manner in which the guide slot for the locking lug of the outer member of the rib is constructed; Fig. 10 is a detail perspective view of one of the outer members of the ribs.

In the embodiment of the invention I provide a collapsible rod or stall" comprising an outer tubular section 1, an intermediate tubular section 2 and an inner section or handle The outer tubular section 'l at the sta'lt' is threaded interiorly in its outer and inner ends, while the intermediate section 2 has on its inner end a reduced exterior-1y threaded stud 4; which is adapted to be screwed into the threaded inner end of the outer section 1. The section 2 has its outer end interiorly threaded and into said threaded end of the section 2 is adapted to be screwed a reduced threaded stud 5 on the inner end of the handle section 3 oil the stall. By constructing the stall and handle in the manner described it will be seen that the sections thereof may be readily disconnected and collapsed when the umbrella is folded, and readily assembled when the rum brella is extended and opened for use.

In the threaded outer end of the outer section 1 of the stall is secured a tip or point (3 having a reduced threaded shank 7 which is adapted to be screwed into the threaded outer end of the section 1. On the shank 7 oil the tip is secured a clamping ring 8 whereby the inner edges oi. the covering 9 of the umbrella secured to the tip between the ring and the enlarged inner end of the tip as clearly shown in Fig. l of the drawing. The handle section 3 oil the statl' may he provided with any :lorm of head or constructed in any desired shape.

The outer end of the tubular outer scclion 1 oi the handle carries the notch which consists of an annular series of radially projecting cars or lugs ll) to which are pivotally and detachably connected the inner ends of the ribs of the umbrella. The lugs 10 are preferably termed by slitting the end of the section 1 inwardly tor a suitable distance and then bending the slitted parts of the metal outwardly at substantially right angles to the stall. The ends of the lugs when thus formed are bent or turned inwardly to form eyes 1.1 adapted to receive a rib tlastening wire l2 which is inserted therethrough and through the inner ends of the ribs as will be hereinafter more fully described.

The ribs of the llllllllellll. comprise inner tubular members 13 on the outer ends of which are formed pairs of a pertured ears 1 .1: between which are engaged the eyes 11 on the ends of the lugs 10 of the notch and with which is engaged the :t'astening wire 12 whereby said inner members of the ribs are detachably secured to the staff. In the upper sides of the members 13 are formed longitudinal slots 15 which gradually decrease in width from the outer toward the inner ends of the members and which open through said outer ends as shown. At or near the inner end of each of the members 13 and communicating with the narrow end of the slot 15 is an offset rectangular notch 16 the combined width of which and the width of the adjacent end of the slot is substantially the same as the width of the wider outer portion of the slot as is clearly shown in Fig. 9 of the drawings. of the inner ends of the members 13 are formed transverse brace receiving eyes or loops 17, said eyes or loops being preferably formed from a reduced extension of the inner end of the members 13 as shown.

Slidably mounted in the inner members- 13 of the ribs are outer rib members 18 each 7 of which preferably comprises an enlarged. cylindrical head or inner end 19 which is of 1 19 of the outer rib members at the outer ends of said heads are formed outwardly projecting guiding and locking lugs 22 which correspond in width to the wider part of the slots 15 in the inner members of the ribs and with which said lugs are slidably engaged. The outer ends of the lugs are preferably provided with oifset heads 23 which engage the outer surface of the rib members 18 adjacent to one side of the slots 15 therein. By providing the lugs 22 it will be seen that when the outer members of the ribs are drawn outwardly to operative posi tions in the tubular inner members of the ribs the lugs 22 will gradually spring apart the edges of the slotted portion of the members 13 or in other words will open said slots to the width of the lugs until the latter are brought opposite to the notches 16 at the outer ends of the slots whereupon the edges of the slotted portion of the rib members will again spring together and engage the notches 16 with said lugs, thus locking the outer members of the ribs 18 in their projected or operative positions. When it is desired to again retract the outer rib members or to push the same back into the inner members it is simply necessary to grasp the outer ends of said outer rib members and to turn or twist the same slightly, thus causing the lugs 22 to spring the edges of the slots On the lower side apart to a sufficient extent to disengage the lugs from the notches 16 whereupon the outer sections 18 of the ribs may be pushed back into the tubular inner members as shown in Fig. 3 of the drawings.

Slidably mounted on the outer section 1 of the staff is a runner as having secured to its outer side a spring catch 25 on the inner end of which is an inwardly projecting stud 2s. The stud 26 works through an aperture 2? in one side of the runner and is adapted to spring into engagement with inner and outer locking apertures 28 and 29 in the outer section 1 of the stafr whereby the run ner is locked in position for holding the ribs of the umbrella in an operative and in an inoperative or folded position. On the outer end of the runner are formed a series of brace attaching eyes 30 said eyes being preferably formed by slittingthe inner end of the runner for a suitable distance and bending or turninothe slitted portions of the metal outwardly as shown. With the eyes 30 is engaged a brace fastening wire 31 by means of which the inner ends of the braces 82 of the umbrella are detachably and pivotally secured to the runner.

The braces 32 are preferably formed from narrow strips of sheet metal which are bent or folded longitudinally and flattened or pressed together at the inner portion of the braces. The inner end of the folded part of the brace is slitted inwardly for a suitable distance along the fold to form attaching lugs 33 which are bent outwardly and spaced apart to the width of the eyes 30 on the end of the runner and with which said lugs 33 are engaged. In the ends of the lugs 33 are formed alined apertures 34; with which the fastening wire 31 of the braces is engaged when passed through the eyes 30 thereby pivotally securing the inner ends of the braces to the runner. Secured to the outer ends of the braces are outer attaching loops 85 which are preferably formed of wire and have their inner ends clenched and rigidly secured between the folded outer ends of the braces. The loops 35 are adapted to be engaged with the eyes 17 formed on the inner sides of the inner ends of the members 13 of the ribs whereby said braces are pivotally or loosely connected at their outer ends with the ribs to support the latter in an open or operative position.

By constructing an umbrella in accordance with my invention it will be seen that in order to fold or collapse the same it is simply necessary to lift the inner end of the v 7 the latch with the outer locking aperture 29 in the staff section 1. In thus moving the runner outwardly the inner ends of the braces are also carried outwardly thereby permitting the ribs to be closed or folded inwardly against the staff. After the umbrella has thus been closed the lugs 22 on the inner ends of the outer members of the ribs are disengaged from the notches 16 in the inner members in the manner described and said outer members of the ribs pushed back into the tubular inner members, thus reducing the ribs to half their full length. After these parts of the umbrella have been thus folded and collapsed the outer and intermediate sections of the staff are disconnected and detached from the outer member or section 1 which as will be seen is of substantially the length of the collapsible or telescoped ribs so that the entire umbrella is now reduced or shortened to a length corresponding substantially with the length of the inner members of the ribs. If desired the length of the folded umbrella may be further shortened by disengaging the tip (3 from the outer end of the staff. It will be noted that the construction and arrangement of the various folding or telescoping parts of the umbrella is such that these parts may be readily released and moved to inope'ative and operative positions when desired.

From the foregoing description taken in connection With the accompanying drawings, the construction and operation of the invention will be readily understood with out requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, What I claim is:

1. In a folding umbrella, the combination with a collapsible stait' having a notch, a runner, and the braces pivotally connected at their inner ends with said runner; of telescopic ribs each composed of a tubular inner member and an outer member, the fori'ner pivoted at its inner end to said notch and at its outer end to one of said braces and having a longitudinal slot in its wall tapering toward its outer end, and the outer member having a head movably mounted in said inner member and provided with a lug projecting through said slot.

2. A telescopic umbrella rib comprising an inner member having a substantially tubular body with a longitudinal slot growing narrower toward its outer end and there provided with a notch in one side, and an outer member slidably mounted within said inner member and having a laterally projecting lug of a width to lit the wider portion of said slot and to spread apart the walls of the same as it is drawn outward.

3. The herein described telescopic umbrella rib comprising an inner substantially tubular member having a longitudinal slot growing narrower toward its outer end and there provided with a lateral notch so that the width at the outer end of the slot and notch is the same as the width of the inner end of the slot; and an outer member having an enlarged and rounded head at its inner end slid-ably fitting within said inner member and provided with a lateral lug of the same width as the inner end of said slot, and a head at the outer end of said lug.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
