Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed April 16, 1910. Serial No. 555,815.

To all whom it may concern:

Be it known that I, IsAK EKLUND, a subject of Sweden, residing at St. Joseph, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Pocket-Umbrellas, of which the following is a specification.

My present invention relates to folding umbrellas of the sliding rib type, my object being to provide a novel combination of novel and improved structural details whereby to form a commercially practical device of this character.

With this in view, my invention resides in the features of construction, arrangement and operation to be hereinafter described with reference to the accompanying draw ings, forming a part of this specification, and in which- Figure 1 is a. longitudinal section through my improved umbrella collapsed and in its case. Fig. 2 is a similar view thereof extended. Fig. 3 is a detail elevation, partly broken away and in section, of the tip and its parts extending into the end stick section. Fig. 4; is a detail section, on an enlarged scale, illustrating one of the section locking dogs. Fig. 5 is a similar view of the runner. Fig. 6 is a similar view, partly inelevation, showing the manner of connecting the ribs and braces, as shown in Figs. 1 and 2. Fig. 7 is a similar view showing a slightly modified form of connection. Fig. 8 is a similar view of another modified form. Fig. 9 is a perspective view of one of the members connecting the ribs and braces and Fig. 10 is a detail sectional view on line 1010 of Fig. 1. Fig. 11 is a detail elevation of a tip constituting a modified form over that shown in Fig. 3. Fig. 12 is a view similar to Fig. 11, with the parts extended, and Fig. 13 illustrates the two members disassociated.

The stick of my improved device comprises a handle section 5 which may have a handle 6 at its inner end, which inner end has an internal plug 7 for a purpose to be hereinafter described. Into the outer end of the handle section 5 telescopes the inner end of the intermediate section 8, into the outer end of which, in turn, telescopes the inner end of the end section 9, at the outer end of which section is rigidly aiiixed the nut 10 to which the inner ends of the inner rib sections 11 are secured. The stick sections are all formedof hollow tubing, preferably hexagonal in cross-section, as shown, so as to prevent the rotation of one with respect to the other, and sections 5 and 8 are provided, adjacent to their outer ends, with openings 24 adapted, when the sections are extended, to receive therethrough spring actuated dogs 12 carried by'the inner ends of sections 8 and 9, respectively, whereby to prevent entire removal of sections 8 and .9 and the. accidental collapsing thereof, these dogs being, however, automatically releasable when collapsing is desired, as will be shown. These dogs 12 are both alike and description of the one in the end section 9. will, therefore, suifice to cover them both. As shown'in Fig. 4, this dog'comprises a shank 13 pivoted at its rear end between the extensions 14 of a. U-shaped member 15 insorted in the adjacent end of the stick, the fulcrum of said shank being a transverse rivet 16 extending through the stick section and thus serving also to hold member 15. The free end of shank 13 has a side shoulder 17 projecting through a slot in the stick section, and is also provided with an extension nose 18 having an inner sloping surface 19. A leaf spring 20, the outer end of which is secured between the inner surface of the stick section and an internal sleeve 21 forced in the end thereof, presses against shank 13 to force its shoulder 17 through the aperture, thus causing the dog to normally assume an angular position whereby the outer end of the said shoulder 17 extends outwardly beyond the inner end thereof. Thus when the inner end of the end section 9 is pressed within the intermediate section 8 to such an extent that the outer end of the latter abuts against the'rib nut 10, forming a stop, the said inner end of the end section 9 will ride the sloping surface 19 of the extension of dog 12 of section 8 and force its head inwardly, withdrawing the inner end of the shoulder 17 beyond the slot or opening 24.

ofhandle section 5 so that section 8 may 2 with a slot 23 through which extends a transverse rivet 23 projecting through the wall of section 9 to limit the sliding movement of said sleeve 22 to a very short one and one which will not affect the outer runner catch 25. This runner catch 25 comprises a shank 26 gradually enlarged toward one end and having a cut-out portion 27 in one side forming a hoo 28 at its extremity, and a rounded shoulder 29 adjacent to said hook. The inner end of the shank 26 is formed with a spring tail 30 intermediately coiled about a transverse rivet 26 extending through the sleeve 22, the extremity of said tail bearing against the wall of said sleeve at a point diametrically opposite to its slot 31 through which the shank 26oz;- tends, said shank, of course, extending through a similar slot in the end section 9. As seen in Fig. 3, the outer end of this sleeve 2 carries a transverse rivet intermediately about which is curved one end'of a rigid heavy wire 34, the opposite end 35 of which is turned back thereon in spaced relation and has its extremity 86 bent very slightly in an outwardvdirection. This wire 3% forms a connection to the tip 37, telescopingly slidable within the outer end of the end section 9, and which has a transverse slit adjacent to its inner end, and the material between said slit and said end, is bent in wardly to provide a catch 38 to loosely receive the bent wire end 35 which projects into said tip. Thus the tip 37 may be moved the length of wire 34: independent oi sleeve 22, and actuate said sleeve at the limits of such movement in relatively opposite directions. This tip 37 also has an intermediate slot 39 through which projects the inner curved end 40 of a, spring member 41 extending therein, the outer end of which is rigid with a plug 1-2 fixed in the outer end of said tip in such manner as to project slightly therebeyond. In the extended po sition, this spring end 40 engages the outer surface of the rib nut 10, and, being rigid with plug as, takes the strain from the outer parts. \Vith the sections extended, it is only necessary to manually press spring end etO inwardly. The parts are then free so that tip 87 may slide in the end section until it strikes and moves the sleeve 22 inwardly to the limit of its inward movement. when its inner end will engage and force the dog 12 of the end section 9 inwardly to release said section and permit it to move inwardly within section 8 and release the dog 12 of the latter so it, in turn, may move inwardly in section 5 until it strikes the plug 7 of the latter, thereby rendering further inward movement impossible, and preventing strain upon the ribs and braces.

The same movement of the tip With relation to the inner sleeve, whereby to actuate the latter at the limits of the movement of the former only, may be readily accomplished by the somewhat different and simplified structure shown in Fig. 11 wherein is shown a. tip 37, the inner portion of which is cut away longitundinally and reduced to one-half of its normal cross-section, and which is provided with a shoulder 73 at its inner end, the outer end of this cut-out portion resulting, of course, in a shoulder 73. The outer end of the sleeve, 22 is likewise cut away and formed with inner and outer shoulders 22 and 22, respectively, whereby when tip 3" is moved toward the sleeve 22, the inner shoulder 22 of the sleeve will contact, and when the tip is moved away from the same, its inner shoulder 73 will engage the outer shoulder 22 of the sleeve. When the reduced portions of the tip and sleeve are placed to coincide, they form the same cross-section and contour of either the body of the sleeve or the tip, and the end shoulders 73' and 22 'fit within the sleeve and tip, re spectively.

The runner comprises an inner sleeve 43 to one end of which is secured the nut H to which the inner ends of the stretchers are secured. and which has an aperture i6 adjacent to said nut, for the hook 28 of the outer runner catch 25, and a second and larger aperture 4:7 to accommodate the enlarged end 48 of the inner runner catch l9 secured to the handle section 5 and depressible into a slot thereof. This enlarged aperture also receives the shoulder 29 of the outer runner catch. The outer sleeve 50 of the runner, which has an enlarged central portion to receive the lower runner catch, and a reduced portion to depress said catch and release the runner when said sleeve is moved upon the inner sleeve, I provide with an outstanding flange 51 upon its end adjacent to the nut 4A of the inner sleeve, so that the operators fingers cannot engage said nut 44, and for afurther purpose of forming a bearing point for one end of a spring 52 coiled about the inner sleeve 43 and bearing with its opposite end against the nut 44 whereby to maintain the outer sleeve in such position that the inner catch 49 cannot fail to spring out and hold the runner when the parts are being extended, this being essential in order that when the stick sections are being pulled out, the engagement of the runner by its inner catch will cause the sections of the ribs (hereafter described) to be pulled out in the same operation. The outer catch prevents the umbrella blowing or turning wrong side out, and acts as a storm stop.

In order that the runnner may be moved freely over the several dogs 12, and that the operators fingers be prevented from being scratched or cut by coming into contact with the edges of said dogs, I provide reinforcing plates 53 suitably secured upon the surface of the stick sections 5 and 8, sur- 12, these plates 53 each having an integral rounding their openings which receive dogs enlargement or rib 54 upon its surface at a point where the outer edge of the dog shoulder 17 projects, the inner edge of this shoulder being flush with the surface of the plate.

As shown in Fig. 6, the outer endsof the inner rib sections 11 are provided at their outer ends with clips 55 fixed thereto and which have inturned flanges 56 extending over the edges of the outer rib sections 57 slidingly disposed in said inner sections, the flanges 56 forming means to engage. spring catches 58 carried by the outer rib sections adjacent to their inner ends, which catches haveflattened transversely projecting heads 58 upon their rear ends, for a purpose to be hereinafter described. At their inner ends, the outer rib sections 57' have members 59, provided with projections to fit the inner contour of said ribs and be secured therein, which projections result in depressions 60 in their outer surface for a purpose which will hereinafter appear. These mem-' bers 59 have lateral apertured flanges 61 at their outer ends forming eyes through and to which the umbrella cover 62 is sewed, and have outwardly extending ears 68, bent inwardly and loosely about the inner rib sections 11 to form guides. 59 have also ears 64, at their inner ends, which project in a direction opposite to that of ears 63, so as to provide means to which the end clips of the stretchers 45 are pivotally connected. The stretchers are provided, adjacent to the clips thereof, with set springs 65 formed of clock spring and bent at the outer ends to fit the inner contour of said stretchers and be secured thereto, the inner ends thereof being pinched to flatten the same whereby, when the stretchers and outer rib sections are moved together, these spring ends will engage in the depressions 60 of members 59 and prevent the catches 58 from being pressed to release the inner rib sections until the stretchers and outer rib sections are squeezed together, when set springs 65 will bear against said catches 58. The form shown in Fig. 7 is almost identical with the form just described, with the exception of set springs 65 which are formed of spring wire, and in each form the depressions 60 of members 59 guide the set springs so that when pressure is applied they cannot fail to fairly strike the flattened heads 58 of catches 58. The form shown in Fig. 8 differs only by a rigid member 66 in addition to set spring 65 which is secured to the stretchers and adapted to strike the catch 58 when pressure is applied. Thus, to fold the umbrella after the same has been lowered and the runner has been moved to engage its inner catch 49, it is only necessary to press spring end 40 inwardly, as before described, and

The members squeeze the ribs lightly but firmly about the stick as the tip 37 is-placed against a support and pressure applied against the han-' dle to cause the stick sections to'telescope. When opening the folded umbrella, it is only necessary to grasp the handle in one hand and the end of the tip 37 in the other hand, and pull them apart as far as they will go. r i

. This construction, it may thus be seen, not only provides an umbrella which is practical and unfailing in its operations of folding and unfolding, but one in which the parts are strong and lasting.

When folded, this umbrella is placed within a flexible casing 67 which I preferably provide with a tab 68 at its outer end so that it may be quickly removed when use of the umbrella is desired.
