CHARLES P. WHITNEY, OF MILFORD, NEW HAMPSHIRE.

FOLDING UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 274,687, dated March 27, 1883.

Application filed August 2, was. (no model.)

To all whom it may concern: I

Be it known that I, CHARLES P. WBITNEY, a citizen of theUnited States of North America, and a resident of Milford, county of Hillsborough, State of New Hampshire, have invented a new and useful Improvement in Folding Umbrellas, of which the following is a specifiexhibit other parts of a portion of the handle,

showing different views of my improved joint or jointing device therefor.

- section on line w m, Fig. 1, looking upward.

5o shoulders t at the four corners.

Fig. 4is across-section online y y, Fig. 1, looking downward. Fig. 5 is a partly-sectional elevation, showing my improved rib-jointing device. Fig. 6 is a side elevation, showing the position of parts when the handle-sections are nearly folded together.

Similar letters of reference indicate corresponding parts. Y r

A represents the central section of the umbrella-handle; B the upper section, and O the lower section, thereof.

The sections A B are united by means of a jointing device, D, which consists of a tube, a, secured on the upper end of section A, and forming part thereof, and having internal shoulders, b, formed at its upper end. The opening about which the shoulders b are formed is designed to be squared or rectangular, corresponding to shape of the bar D, whose upper end is secured by pivot h in the link D while the upper end of the latter is held by pivot r to the lower end of the round bar D the upper end of the latter being screwedor otherwise rigidly secured in a ferrule, k, on the handle-section B. Bar D is round, with an upper end of square cross-section, thus forming A pin, a, projecting from the sides of the bar D and rest- Fig. 3 is a crossing on the shoulders b,prevents the detachment of one handle-section from the other. D is cut away at w' to form a recess, which will receive the edge of the socket when the umbrella is folded, and thus the parts will lie closer together, as shown in'Fig. 6.

In the base of the socket formed by the tube a is secured a spiral springmn, whose'other end is made fast to the lower end of the barv D, and assists by its tension in drawing the 'be pushed upward until it is in contact with section B, and the shoulders 15 on the bar D thencoming above the internal shoulders, I), a slight or partial turn of the section A will bring the shoulders it across the internal shoulders, b, whereby the handle-sections A B are held straight, and. firmly in line with each other, and the action of the spring m at the same time tends to prevent the accidental returning of the handle-section A.

The handle-section C is preferably provided with ascrew, as shown at n, and can be there by screwed.into the lower end of the section 0, and be readily detached therefrom when desired, and said sections A O are preferably united with a joint, 7c.

The umbrella-ribs]? are jointed, as shown at 0, at about midway of their length, so that their lower portions may be turned back or folded upward, and they are provided with short metallic re-enforcin g pieces g about their jointed ends, and over .and upon each rib F is a sliding sleeve, G, that is pivoted, as shown at s, at its upper end to the stretcher H. The

runner I differs from the ordinary umbrella- .runncr in having the notch-wheel o near the the'ribs F are straightened or unfolded, and

This bar rib-joints 0, and the sleeve-sprin gs p, pressing against the jointed rib ends, serve to hold the sleeves G in their position while opening the umbrella, and tend greatly to increase the rigidity and stiffness of the joints and to prevent any undue freedom of movement of the lower ends of the umbrella-ribs.

-I do not broadly claim a folding umbrella, as I am aware that others have been made with one or two joints in the handle, but,

. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a folding umbrella, the handle having ajoint atD, combined with ribs havingjoints which, when folded, will lie adjacent to the joint D in the handle, and with a runner and stretchers carrying sleeves which embrace and cover the hinged ends and pivots of the ribs, whereby the cover is protected from the wear caused by the hinges and the rib-joints are supported when the umbrella is opened, as set forth.

2. The combination, with thejoint D, of the spring m, having one end connected to the bottom'ot' the socket a. and the other end to the joint by a pin, 0, such pin also serving as a stop for the joint 1) against the flanges b, as set forth.

3. In a folding umbrella, the combination, with thehandle-sections,of the jointing device D, consisting of tube a, provided with internal shoulders, 1), bars D D the latter having shoulders t, pivoted link D and. spring m, constructed, arranged, and adapted to operate substantially as herein shown and described.

4.- In a folding umbrella, the combination, with the jointed ribs F and stretchers H, of the sliding sleeves G, attached to said stretchers, and provided with internal springs,p, substantially as and for the purpose described.

5. In a folding umbrella, the combination of the ribs F, jointed at 0, and having re-enforcing pieces 9, the stretchers H, and the runner I, with the sleeves G, having springs 9, as and for the purposes specified.

6. In a folding umbrella, the combination, with the jointed ribs F, provided with menforcing pieces gand stretcher-attached sleeves G, of the pivotss, substantially as herein shown and described, whereby said sleeves are prevented from sliding too far on the said ribs, as set forth.

7. In a folding umbrella, the combination of the handle-sections A B O, jointed at D and K, substantially as described, and the ribs F, hinged at 0, and having re-enforcing pieces g, with the runner I, stretchers'H, and sleeves G, having springs 19, as and for the purposes set forth.

8. In a folding umbrella, and in combination with the jointed handle, the rectangular bar D, having recesses w, adapted to receive the edge of the socket a, and to serve as and for the purposes specified.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 24th day of July, 1882.

A. B. HUTCHINSON, O. R. HOWARD.
