ENDELL T. CRANE AND EDWARD H. CRANE, OF ODEBOLT, IOWA.

FOLDING UMBRELLA.

To all whom it may concern:

Be it known that we, ENDELL T. CRANE and] EDWARD H. CRANE, citizens of the United States, residing at Odebolt, in the county of Sac and State of Iowa, have invented certain new and useful Improvements in Folding Umbrellas, of which the following is a specification.

This invention relates to umbrellas and refers especially to that class of such devices which is known as folding umbrellas.

An object of this invention is to construct an umbrella frame which can be folded in a few simple operations and which will be locked in an open position when raised.

Another object of this invention is to construct an umbrella by which the stafi can be folded upon itself and so that the ferrule upon the end of the staff may be telescoped in the upper end of the staff to reduce the size of the umbrella to less than one half of its original size.

A further object of this invention is to produce a device of this character that will be simple in construction and in the number of its parts, durable and easy of manipulation and manufacture.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the complete device in an open position. Fig. 2 shows the umbrella in side elevation in a closed position. Fig. 3 is a detailed and enlarged sectional view of the staff showing the joints thereof. Fig. 4 is an enlarged and detailed view of one of the ribs showing the joint and locking means therefor. Fig. 5 is a cross section centrally of the lower section of the staff.

Referring now to the drawings, and 11 designate the two sections of the staff. The section 10 is recessed transversely at its lower end as at 12 and carries a depending rod 13 intermediate of the recess which extends slightly below the extremities of the section 10 where it is curved upon itself to form an eye 14. A. link 15 is secured at one end to the rod 13 through the eye 14 and extends Specification of Letters Patent. Patented Sept, 21, 1909,

downwardly where it engages in an eye 16 formed upon the upper extremity of a rod 17. The rod 17 is inclosed by a casing 18 which carries a tongue 19 transversely disposed across the upper ends thereof and which is normally engaged in the recess 12. The casing 18 is provided with a sleeve 20 intermediately disposed within the same which is provided with a central angular bore through which the rod 17 is passed. The sleeve 20 is secured in the casing by a pin 20. The rod 17 is angularly formed intermediate of its length as at 21 for the purpose of preventing rotation of the same but allowing free vertical reciprocation thereof. The casing 18 is provided with an annular flange 22 which extends outwardly and which is fitted into a depressed portion 23 formed in the upper extremity of the section 11. The section 11 is provided with an inwardly extended flange 24: which engages the flange 22 and prevents the casing '18 from being removed from the section 11 but allowing free rotation of the same. The rod 17 extends below the casing 18 into the section 11 where it is threaded to engage through the threaded central opening of a nut 25 which is carried by the section 11. The lower extremity of the rod 17 extends down into the bottom of the section 11 and is headed as at 26, to prevent the rod 17 from being withdrawn from the section 11.

The upper extremity of the section 10 is hollowed out to receive the point 27 of the staff. In the upper end of the section 10 there is a double bayonet slot 28 in which a stud 29, which is carried by the point 27, is engaged and travels. A notch 30 is disposed upon the upper end of the section 10 through which the point 27 is adapted to slide. A spring 31 is secured between the lower end of the hollow portion upon a pin 4A disposed through the section 10 and the under side of the point 27 for the purpose of raising the point outwardly in the inner and outer positions. The ribs of the umbrella are provided with apertures at their upper ends for the purpose of pivoting the same to the notch 30 and to radially extend therefrom. The ribs each comprise two sections 32 and 33 which are transversely recessed at their inner ends which are hinged by'the plate 34 through the medium of pins 35 and 36 which are passed through the sections 32 and 33 and through the opposite extremities of the plate 34 which is fitted into the recesses. The sections 32 and 33 are locked in an open position asleeve which is slid ably mounted upon the rib and is pivotally connected to a runner 38 slidably mounted upon the staff, by a stretcher 39. The stretcher 39 carries an upwardly extending arm which is extended outwardly when it engages in a channel 41 against an abutment 41-3 formed upon the section 32 of the rib when the umbrella is extended to its open position. The arm 10 serves to lock the sleeve in rigid position directly over the plate 34 preventing the swinging of the section 33. The section 33 carries a leaf spring 12 which engages the inner side of the sleeve 37 and serves as an auxiliary hold for the same.

The operation of the device is as follows: When the umbrella is opened and it is desired to close the same the runner 38 is drawn down the staff and the arm 10 is disengaged from the channel 411. When the stretcher 39 is disposed at a sufficient angle the sleeve 37 is moved upwardly upon the section 32 to release the plate 34 and allow the section 33 to be folded up upon the section 32. The section 32 is now folded down against the staff and the runner 38 is forced upwardly carrying the sleeve 37 to the upper portion of the section 32; The point 27 is rotated through a slight angle to release the stud 29 from the slot and is then forced against the spring 31 down into the hollowed upper end of the section 10 ofthe stafi where it is again rotated and secured in that position in the bayonet slot;- The sec tion 11 is now rotated and the rod 17 is fed upwardly until the tongue 19 can be withdrawn from engagement with the recess 12 and the section 11 can be folded up upon the section 10-, the link 15 acting as a hinge;

The uinbrella is now folded and ready to be carried or packed fortransportation.

What is claimed isf A stafi for a folding umbrella comprising a section having a recess in thelower end thereof and a hollowed portion in the upper extremity thereof, a point slidably disposed within said hollowed portion, a spring in said hollowed portion for holding said point in position, a second section, a casing swiv-' eled in the upper end of said second section, a tongue disposed upon the upper end of said casing for engagement in .said recess, a linked rod carried by said first section ex tended through said casing, said rod being angularly formed interinec'liate of its length, a sleeve in said casing having an angular bore therethroi-igh, said intermediate portion of said rod being engaged in said bore and a nut carried by said second section for engagement with the lower threaded extremity of said rod.-

In testimony whereof we affix our signatures, in presence of two witnesses;
