accipie Upper pole 38 carries any conventional umbrella canopy (not shown on the drawing) comprising a cover, umbrella ribs, sliding spreader ring or collar for opening or closing the umbrella, etc. Pole 38 has fixed to the lower end thereof a casting 39. This casting comprises a cylindrical portion to fitting snugly within pole 38, and two spaced extending arms 4i and 42. The projections l and H of casting l3 fit snugly within the space between arms M and 42, as shown in Figure 2. Extremities of arms ll and 42 are of convex or rounded shape as indicated by the reference character 43. Casting I3 is provided with concave or complementary rounded shoulders M. Desirably castings l3 and 39 are shouldered so as to abut in flush relationship against the ends of the poles It and 38, respectively. The outer surfaces of the assembled castings, as best shown in Figures 1 and 2, are cylindrical and of uniform diameter, the outside diameter being the same as that of the poles. The castings may be fixed to the poles in any suitable manner.

Casting 39 is pivoted to casting l3 by a pivot pin 45 which passes through arms ii and t2 and projections l8 and H. Thus, the upper pole 38 carrying the canopy is pivotally mounted on the top of the hollow lower pole Ill provided with the actuating mechanism for tilting the umbrella canopy. It will be understood that while the drawings show castings associated with the poles, which is preferred because of ease of manufacture, casting i3 and pole It may be formed integrally and likewise casting 3t and pole 33 may be made integral. In other words, the assembly of pole Ill and casting l3 may be considered the lower pole to which is pivoted the top pole consisting of pole 38 and casting 39.

A link 45 has one end pivotally connected to the top of rod 28 and the other end pivotally connected to one end of a second link ll. A pivot pin it passes through this link 4i and the projections iii and ll of casting it, thus pivotally securing this link to these two projections. End 49 of link ll is provided with a slot 50 in which is slidably disposed a shoe 5i. A pin :52 passes through this shoe and is suitably mounted in the casting 39; shoe 5| is free to rotate on pin 52 and vice versa so that these two parts can move relatively to each other.

The lower portion of link ll is positioned in slot i8 and the upper portion of this link ti fits within interior opening 53 in casting 39. Link 46 fits within slot i8 and the lower extension thereof shown in Figure 2 in casting it. In this way when the umbrella is in the non-tilted position the linkage mechanism is disposed within the cylindrical confines of the castings. Desirably link is provided with a cut-away portion 5% in the area near the pivot pin 45 to permit link ll to be moved to the position shown in Figure 1 without contacting this pivot pin it.

In operation, when it is desired to tilt the urnbrella, it is only necessary to loosen ball 35, should it have been tightly screwed on rod 25, and then move lever 26 upwardly from the position shown in Figures 1 and 2. This will raise the actuating rod l9 and link 45 causing the latter to move outwardly from the casting it through slot 58. This movement of link it: e1:- fects pivotal movement of link Al about its pivot 68 exerting a thrust on shoe 5i carrying pin 52 mounted in casting 39 which effects tilting movement of upper pole 38. As the movement continues, link 41 moves outwardly relative to casting 39 to the position shown in Figure 3, with the shoe 5! sliding in the slot 50. The above described movement results in further compression of coil spring 3'! which thus tends to counterbalance the weight of the superstructure, chiefly the canopy and results in smoother operation than would take place in the absence of the spring. Once the desired tilt has been imparted to the upper pole the ball 35 is tightened on threaded end 33 of rod 26 to clamp washer 34 against the walls 35 and 32 of the quadrant. This clamping pressure, the action of the spring 31' and the linkage mechanism disclosed, firmly maintain the umbrella canopy fixed in the desired tilted or straight position.

It will be noted the umbrella of this invention can readily and quickly be tilted in that a simple movement of pivoted rod 26 after loosening ball 3?: is all that is necessary to effect the tilting. Accordingly, applicants umbrella can be adjusted to the desired angle of tilt much more quickly than prior known tiltable umbrellas. It will be further noted that applicants umbrella is of rugged design.

Since difierent embodiments of the invention could be made without departing from the scope of this invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted illustrative and not in a limiting sense.

What is claimed is:

l. In a tiltabie umbrella, in combination, a hollow lower pole, a vertically reciprocable actuating shaft disposed within said hollow pole, a member having a portion disposed within said hollow pole, pivoted thereto, connected to said shaft and having another portion extending exteriorly of said hollow pole and arranged to be actuated about said pivot to reciprocate said shaft, an upper pole pivoted to said lower pole, and pivoted links connecting the upper end of said shaft to said upper pole, the connection between said links and. the upper pole being disposed above said pivotal connection between the upper and lower poles.

2.
