To all whom t may concern.-

Be it known that I, SAMUEL J VILSON, a citizen of the United States, residing at Minnesota Lake, in the county of Faribault and State of Minnesota, have invented a new and useful Folding Umbrella, of which the following is a speciiication.

This invention has relation to folding umbrellas, and aims to provide a device of this character which is capable of being folded into a compact form with the greatest facility, and which when extended for use can be locked securely against accidental movement or slipping of the folding parts.

The improvement consists primarily of a novel locking mechanism for securing the braces in a Xed relative position when the sections of the ribs are extended to their fullest length, and which will admit of the unlocking and the releasing of the braces and movable rib-sections at one and the same operation.

The improvement also consists of the peculiar formation of the locking devices between the braces andthe rib-sections, whereby a turning of the braces on their longitudinal axes will effect a locking and unlocking of these parts when the component parts of the locking devices are in register.

The invention further consists of the novel means for rotating or turning the braces about their longitudinal axes and for securing them in the adjusted position.

The invention also further consists of the novel features and the peculiar construction and combination of the parts, which hereinafter will be more fully described and claimed, and which are shown in the accompanying drawings, in which- Figure 1 is a sectional view of a folding umbrella constructed in accordance with and embodying the vital features of the invention. Fig. 2 is a view similar to Fig. 1, showing the parts folded, the coverbeing removed. Fig. 3 is a detail perspective view, partly `in section, showing the relative disposition of the parts when the braces and the rib-sections are locked. Fig. 4 is a view similar to Fig.

3, showing the relative disposition of the parts when released or unlocked. Fig. 5 is a perspective view of the locking device between the braces and the rib-sections. Fig. 6 is a perspective view of the operating-ring. Fig. 7 is a detail view of the lower end of a brace. Fig. 8 is a side elevation of the operating-'ring The stick 1 is divided midway of its ends, and the two parts are connected together by a plate 2, having its end portions fitted into corresponding kerfs formed in the contiguous ends of the separated parts, said plate having pivotal connection at its ends with the respective parts and providing a hingejoint which will readily admit of the parts being folded, said joint being strengthened by a sleeve 3, which is slipped thereover when the parts are in alignment. The tip 4 is detachably connected with the end of the stick in any desired manner, and, as shown, has a reduced portion 5 adapted to enter a correspending opening in the end of the stick, and this tip when removed is placed in an opening Gin the butt or handle portion of the stick, said openin g being closed by a cap 7.

The notch 8 is of ordinary construction and secured to the stick in the usual way, and the ribs 9 are fastened thereto in any approved manner. The ribs comprise telescopic sections 10 and 1l, the former being tubular and slotted in its lower side, and the latter or movable section 11 being preferably a solid wire. The end of each section 10 is strengthened and reinforced by a ring 12, which also provides a stop to prevent the movable section 11 from accidental disengagement therefrom. A stop 13 is located in proximate relation to the ends ot' the sections 10, and comprises a plate which has its end portions bent around and made fast to the sections, said plate having oppositely-extendin g projections let curving outwardly from and in line with the respective sections 10, to which the stops are attached. The movable sections 11 have their upper ends recurved te form hooks 15, which extend through the open sides of the sections 10 and which have their ends enlarged to provide stops to retain the couplings 1G in proper position thereon. rljhe coupling 16 has an enlarged portion 17 to enter the space between the projections 14, so as to limit the relative movements of the sections 10 and 11 in either direction, and this coup- IOO ling is adapted to turn upon the hook or recurved portion 15 to bring the enlarged part 17 in line with the projections 1l, or out of the path of the same, according as it is required to lock the sections 10 and 11 in an extended position or release the same to admit of the section 11 sliding within the section 19.

It will be understood that there will be a coupling for each section 11 and a stop 13 for each section 10, and the coupling, in connection with the stop, forms the locking device for the rib-sections to hold the latter in an extended position.

The braces 18 have their upper ends pivotally connected with the couplings 1G and their lower ends attached to the runner 19 by means of the fastening-wire 20, which latter is applied to the runner in the ordinary manner. The lower ends of the braces are bent to form outwardly-extending arms 21, and have their end portions recurved to form stops 22, said end portions having an offset to provide a stop 23 contiguous to the stop 22 and between which stops the wire 2O is located so as to prevent accidental disengagement of the lower ends of the braces from the fastening-wire 20. The fold or bight form ed by recnrving the end portion of the brace is expanded laterally to provide engaging-points 2-1 for the operating-rin g 25 to make contact with when operating or turning the braces to lock or release the rib-sections.

A locking-sleeve 2G is mounted upon the upper portion of the runner 19, and has its upper enlarged end formed in its top side with a series of tangentially-formed recesses 27, which are adapted to receive the outwardlyextending ends 21 of the braces and secure the latter in a relatively-fixed position against turning, whereby the parts 17 and 13 are held in operative relation to maintain the telescopic sections of the ribs in an extended position. This locking-sleeve 2G is provided at its lower end with an annular enlargement 2S to be grasped by the hand when it is required. to move the locking-sleeve upon the runner, and the sleeve is held from turning on the runner and guided in its longitudinal movements by a pin 29 projecting laterally from the runner 19 and passing through a longitudinal slot 30 in the side of the lockingsleeve 2G, and this locking-sleeve is secured upon the runner in its upward movement thereon by means of a spring-catch 31 extending from its lower end and adapted to engage with the lower flanged end of the runner 19.

The operating-ring 25 is mounted upon the locking-sleeve 2G, and is limited in its turning thereon by having a transverse slot 32, through which extends the pin 29, and its lower end has a stop to engage with a corresponding stop 3l on the locking-sleeve 2G, whereby the operating-ring is held at the limit of its movement in either direction. The upper portion of the operating-ring is enlarged, as shown at 35, and this enlarged portion encircles the upper portion of the runner and the outwardly-extending arms 21 formed at the lower ends of the braces 1S, and a series of vertically-disposed grooves 3G are formed on the inner side of the enlarged portion 35 to receive the said arms 21, and by this means the braces are turned on their longitudinal axes to bring the enlarged portions 17 of the couplings into or out of line with the projections 1-1- of the stops 13. Then it is required to release the rib-sections, the operating-ring 25 is turned so as to throw the enlarged portions 17 out of line with the projections l-it, and by moving the runner 19 upon the stick the sections 11 will slide within the tubular sections lO, thereby reducing the length of the ribs nearly one-half. By moving the sleeve 3 the hinge-joint between the parts of the stick can be broken and the parts folded, as shown most clearly in Fig. 2, and to further reduce the length of the umbrella the tip is removed and placed within the opening 6 in the butt or handle.

Then it is required to unfold or open the umbrella, the parts of the stick are caused to align and the hinge-joint stiftened by moving the sleeve 3 thereover, and the runner 19 is moved down upon the stick until the ribsections are properly extended, This will occur when the enlarged portions 17 of the couplings are brought opposite the stops 13. The locking-sleeve is moved upon the runner to release the operating-ring, and the latter is turned to bring the enlarged portions 17 in register with and between the projections 14E, thereby locking the rib-sections in their eX- tended position, and the locking-sleeve is again moved to cause the outwardly-extending arms 21 to enter the tangential recesses 27, thereby securing the parts 17 and 14 in locked relation, as the engagement of the arms 21 with the recesse 27 secures the braces from any longitudinal rotation. It will be seen that the locking-sleeve serves both to lock the operating-ring 25 and the braces 1S.

The constructionherein shown admits of the umbrella being folded into a small compass, and when in use prevents accidental slipping of the part-s, because the latter are held in locked relation and are secured from accidental displacement by positive means. The covering will be applied and secured to the ribs in the Ordin ary manner, and the parts can be differently related to meet the different makes of this class of devices. Hence it must be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacriiicing any of the advantages of this invention.
