UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 752,032, dated February 16, 1904.

I Application filed June 17, 1903. Serial No. 161,870. (No model.)

To all whom it may concern:

Be it known that I, CHRISTEN N. CHRISTEN- SEN, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Umbrellas, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to new anduseful improvements in umbrellas, and has for its object, among other things, the construction of an umbrella with parts so connected that the umbrella may be folded whereby it will occupy the minimum amount of space.

To these and other ends my invention consists in the umbrella having certain details of construction and combination of parts, as will be hereinafter described, and more particularly pointed out in the claim.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures, Figure l is a view of the umbrella shown in its closed position. Fig; 2is an enlarged fragmentary view of an umbrella with my improvements shown in its open position; and Fig. 3 is a fragmentary detailed view of one of the ribs, extension-ribs, and stretchers. i

In carrying out my invention I construct the umbrella-rod preferably of three sections, (designated in the drawings, 1, 2, and 3,) which sections are slidable within each other telescopically and are held in their open positions by the springs 4, which are of the ordinary construction and project through a slot in the side of said sections when in register therewith, as shown in Fig. 2. Any means can be used to hold these sections in their extended positions, and I do not, therefore, limit myself to the use of a spring such as the one shown and described herein.

Adjacent to one end of the section 1 is the head 5, to which the ribs 6 are fixed thereto in any preferred manner. These ribs are preferably tubular in form, having a longitudinal slot 7 in the under side thereof, which extends substantially the whole length of said ribs, and in the upper side near the outer end thereof is a slot 8. Slidable within said ribs 6 are the extension-ribs 9, having a radially-projecting lug 10 adjacent to the inner end thereof and to which is secured one end of the stretchers 11, the other end of which is secured to the umbrella-runner 12, slidable upon the rod in the usualmanner. The extension-ribs 9 when the umbrella is closed are within the interior of the ribs 6, and the outer ends of said extension-ribs are substantially flush with the outer ends of said ribs. hen the umbrella is opened, the extension-ribs are drawn outwardly until the stretchers 11 engage the outer end of the slot 7 when the inner ends of the extension-ribs 9 are canted, so that the lug 1O thereon enters the slot 8 in'the rib and is thus held in its outward position.

The numeral 13 designates the umbrellacover, which is preferably made of lightweight rubber and is secured at its outer edges to the outer ends of the extension-ribs 9 in any preferred manner, the specific means for doing which not being material to my invention is not shown or described in detail.

To open the umbrella, the section 3 is first grasped and drawn outwardly and until the spring t therein registers with the slot in the section 2 and is there held against further movement. The section 2 is then drawn outwardly until the springt therein engages the recess in section 1. The runner 12 is now grasped between the fingers and slid over the sections 1 and 2, the spring 4 in the section 2 being depressed sufiiciently at this time to permit it to pass. This movement of the runner draws the extension-ribs 9 outwardly through the ribs 6 until the stretchers 11 engage the end of the slot 7. During this operation the rubber covering 13 is stretched with the movement of the extension-ribs 9. The position of the runner is then reversed, it being moved on the sections toward the'head 5, and immediately the position of the runner is reversed the stretchers 11 are moved lengthwise slightly and the lugs 10 upon the extensionribs 9 are thrown into the recess Sin the ribs 6, thus preventing a return movement of the extension bars 9. \Vhen the runner has passed the spring at in the section 2, it is released and held against a downward movemen t by its engagement with said spring.

To close the umbrella, the spring 4, just referred to, is pressed inwardly a suflicientdistance to permit the runner to pass the same, and the runner is moved on the rod until'the ribs are brought parallel therewith. The outer ends of the extension-ribs 9 are then grasped in the hand and canted sufficiently to release the lugs 10 from the slots 8, after which the runner 12 is moved along the rod toward the head 5, sliding the extension-ribs 9 into the ribs 6 and bringing the ribs 6, extension-ribs 9, and stretchers ll parallel with and against the section 1. The closing of the umbrella is facilitated by the contraction of the rubber cover 13, which is released as soon as the lugs 10 are disengaged from the slots 8.

The cover 13 is preferably secured to the rod by a nut 14:, which is threaded upon the end of section 1, this manner of securing the cover permitting the same to be readily remouled and another one attached thereto, if desire There are many minor changes and alterations that can be made within my invention aside from those herein shown and suggested,

amass claim as new, and desire to secure by Letters umbrella-rod consisting of telescoping sections; of a head secured to said rod; tubular ribspivotally secured to said, head and having a slot in the under side thereof and another slot in the top thereof shorter than the firstmentioned slot and near the outer ends of said ribs; extension-ribs movable within said tubular ribs and having rigid lugs upon the top side and near the inner ends thereof; a runner upon said rod; stretchers pivotally secured to said umbrella runner at one end, passing through said under slot and pivotally secured to the aforesaid extension-ribs at the other end, said stretchers being so arranged that the engagement thereof with the outer end of said under slots will cant said extension-rods so that said lugs will be thrown into said top slots and there hold said extension-ribs against withdrawal while said stretchers are held in their open position; and a rubber cover connected with said rod and ribs.

In testimony whereof I aflix my signature in presence of two witnesses.
