FOLDING UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 608,453, dated August 2, 1898. Application filed December 14, 1897. Serial No. 661,836. (No model.)

To aZZ whom it may concern: I

Be it known that we, FRANK G. GROVE and FRANK E. STOVER, of Luray, in the county of Page and State of Virginia, have invented a new and useful Improvement in Folding Un1 brellas, of which the following is a full, clear, and exact description.

The object of our invention is to simplify the construction of the framework of folding umbrellas, and particularly to so construct telescopic ribs for such umbrellas that when theribs have been drawn out to their full length and the runner is carried upward on the stick the action of the contracting por tions of the two ribs will be such as to hold the ribs immovable and render the telescopic or sectional ribs as strong in every particular as a rib made in one piece.

Another object of the invention is to provide for a simple, durable, and economic construction of a folding stick, and, furthermore, to provide a spring for the lower section of the stick adapted to hold the runner when the umbrella is closed, which spring is readily removable from the stick and may be conveniently placed therein, the saidspring fur therlnore serving-to limit the movement of the lower section of the stick and lock the said lower section of the stick either when drawn from the upper section of the stick or when carried to an engagement with said section.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to .be had to the accompanying drawings, forming a part of this specification,

I in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of'a portion of an umbrella-frame constructed in accordance with our invention, the frame being opened and the sections of the stick continuous. Fig. 2 is a side elevation of the fram'e'shown in Fig. 1, but shown folded. Fig. 3 is an enlarged sectional view through the lower section of the stick and a portion of the intermediate section, illustrating the lower section as havingbeen drawn downward from the upper sectionto admit of the folding of the stick. Fig. 4 is aview similar to Fig. 3, showing the tion, as shown in Fig. 1.

relative positions of the intermediate sticksection and the lower or handle section of the stick when said handle-section of the stick is carried up to an engagement with the upper section of the stick to render the handle continuous. Fig. 5 is an enlarged side elevation of the overlapping ends of the members of a rib and a portion of a stretcher connected with the rib. Fig. 6 is a transverse section taken on the line 6 (S of Fig. 5. Fig. 7 is a side elevation of the upper rib-section, drawn upon a small scale; and Fig. Sis a side eleva tion, partly in section, of the overlapping ends of the members of a rib and a portion of a stretcher, the rib being extended and showing the cam of the inner section thereof in engagement with the pivot of the stretcher.

A represents the stick of the umbrella. This stick is made in sections, the upper section 10 whereof is provided with the usual spring 11 for holding a runner near the ferrule end of the stick, and the said upper section 10 is provided with a reduced portion 12 at its lower end, as shown in dotted lines in Fig. 1 and in positive lines in Fig. 2. The intermediate section 13 is of the same diameter as the reduced diameter 12 of the upper section 10. The upper portion of the intermediate section 13 is preferably made solid and the lower portion tubular, as shown in Fig. 3, and the lower portion 14 of the stick is tubular throughout and is held to slide upon the intermediate section and upon thereduced portion of the upper section to an engagement with the shoulder of the upper section formed by said reduc- The lower section 14 of the stick is secured in a handle 15 of any desired shape. Alink 16 is pivotally connected with the upper end of the intermediate section 13 and the reduced portion 12 of the uppersection 10, the link 16 being made to enter slots in both of said sections, as shown in Fig. 2. l V

In the lower or tubular portion of the intermediate section 13 two opposing longitudinal slots 17 and 18 are made, as shown in Figs. 3 and 4. The slot 17 extends through to the lower end of'the intermediate section, while the slot 18 does not extend quite to the lower end, whereby a cross-bar 19 is formed. At a suitable point in the lower portion of the lower section it of the stick an opening is made, through which the lower end of a spring I is adapted to extend, this projecting portion of the spring 13 being adapted to enter the usual slot in the runner 28 when the said runner is carried down the stick in closing the umbrella. The spring B is of peculiar construction, the body 21 being curved. In fact, the spring is curved from end to end, and between the center and upper end of the spring, at what may be termed its back or concaved edge, a bearing is formed, which enables the spring when introduced into the lowerend of the stick to be fulcrumed upon the inner wall of said section.

A spur 23 is formed at the upper end of the spring at its concaved edge, and the said spur is passed through the slot 18 in the intermediate section above and across the cross-bar 1!) and is made to enter an opening 24, produced in the lower or handle section of the stick. This spur, together with the fulcrum, serves to hold the spring in place, and below the spur a shoulder 25 is [formed on the spring, adapted for engagement with the cross-bar 1.9 when the handle-section of the stick has been drawn entirely from engagement with. the upper section 10 and slightly beyond the upper end of the intermediate section 13 of the stick. Thus the shoulder 25 serves to limit the downward movement of the handle-section.

The upper end of the spring, or that containing the spur and the shoulder, may be termed the head of the spring, and the tail or bottom portion of the spring is enlarged, as shown at 26, beingat this point of greater width than at any other point, and the tail portion of the spring normally extends out through the opening 20 in the handle-section of the stick. in the enlarged or tail portion of the spring I a recess 27 is made, and the outer edge of the enlarged portion 26 of the spring above the recess 27 is beveled inwardly and upwardly. \Vhen the handle-section of the stick is carried upward over the reduced portion 12 of the upper section and engages with the shoulder on the said upper section, as shown in Fig. 1, the cross-bar 1!) of the intermediate section will ride over the inclined portion of the tail of the spring and enter the recess 27, as shown in Fig. 4', and in this mannor the handle-section ol' the stick is locked to the upper section, and the stick will be as rigid as it made in one piece.

The runner 28 is of the ordinary construction and likewise the stretchers 2.), connected with the runner. The main feature of the invention relates to the construction of the ribs 0. These ribs are made in two telescopic sections 30 and 31, the section 30 being the upper section and is connected in the usual way with the crown 232 of the stick. The section 31 of the rib is the outer or lower section and is held to slide upon the upper or innersection, both sections being paragon. The stretcher 29 for a rib is connected with the outer section of the rib preferably by means of the usual lap 33, which is rigidly attached to the said lower portion of the rib at a point removed from its ends, providing for a back bearing of the lower or outer section against the upper section of arib, as shown in Figs. 5 and (5. The lap is provided with cars 34:, through which ears the pivot-pin 35 of a stretcher is passed, the pin being close to the underside edges of the upper section 30 of a rib.

The extreme outeror lower end of the upper section of a rib is in the same plane with the body of the rib; but near the outer or lower end portion of the upper section of the rib the said rib is concaved upon its upper face and convexed at its lower edges, l'n'oviding lower cam-surfaces 36. Thus it will be observed that after the lap of the lower section of the rib has passed the curved or cam portion of the lower section of the upper memberot the rib the lowersection or member of the rib will move freclyon the upper section or member, enabling the upper end of. a lower section or member 01. a rib to be carried quite close to the crown 32; but when the lower section is drawn downward so as to impart to the rib its full length the curved or cam portion of the upper section of the rib will be straightened out by reason of the convexed or cam edges bearing upon the pivot-pin 35, and the two sections of the rib will have practically four .lirm points of contact, one point of contact being between the upper end of the lower ribsection and the upper surface of the upper ribsection, another point of contact'being between the lower end ol" the upper rib-section and the under Face of the lower rib-section, while the two other points of contact occur one between the pivot-pin and the convexed or cam edges of the upper rib-section and the other between the opposing surfaces of the two ribseetionsinnnediatcly within thelap 3 3.

It is evident that when contacts are made between the rib-sections, such. as has just been described, the sectional rib for all practical purposes is as strong as when made in one piece, and a sectional rib may be raised and lowered fully as well as the ordinary rib. \Vhen the umbrella is to be folded, the outer ends of the lower sections of the ribs are slightly tapped, so as to carry the lap beyond the cam edges of. the upper rib-sections, after which, as heretofore stated, the lower rib-sections may be readily slid on the upper rib-sections in direction of the crown. After the ribs have been reduced. in length, as stated, the tail of the spring 13 is pressed inward, releasing the spring from engagement with the cross-bar 19 of the intermediate stick-section, whereupon the handle section of the stick may be drawn downward, uncovering the link 16 connecting the upper and intermediate sections of the stick, and the handlesection of such stick may then be folded parallel with the upper section, as shown in Fig. 2, reducing the length of the umbrella about one-half and enabling it to be carried. in. a traveling-case, if desired.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1.
