UMBRELLA-RUNNER.

SPECIFICATION forming part of Letters Patent No. 508,189, dated November 7, 1893.

Application filed February 5, 1891- Serial No. 380,363. (No model.)

had to the accompanying drawings, forming a part hereof.

My invention relates to an improved runner-locking mechanism so constructed that the act of urging the runner endwise will cause the same to lock and unlock both in its upper and its lower positions.

In the accompanying drawings,Figure 1 is a perspective view of my device as it appears in its elevated and locked position, the

upper part of the outer sleeve being broken away to show the inner parts. Fig. 2 is a transverse vertical section of the same on the line 22 of Fig. 1, the parts being in the position as when the umbrella is raised. Fig. 3 is a vertical section showing therunner unlocked as it appears when commencing its downward movement. Fig. 4 is a vertical section showing the parts in the position as when the umbrella is closed. Fig. 5 is a perspective Vl6W of the runner tube with the locking catches thereon. Fig. 6 is a perspective view of the inner portion of the sliding sleeve which surrounds the runner tube to disengage the catches. Fig. 7 is a CI'OSSTSGG- tion on the line 77 ofFig. 2, showing the position of the parts when locked. Fig. 8 is a cross-section on the line 8-8 of Fig. 3, showing the position of the parts when unlocked. Fig. 9 is a cross-section on the line 99 in Figs. 3 and 4..

Referring to the drawings,-A represents the stick or handle of the umbrella provided at its upper end on opposite sides with two studs or pins 0., and at its lower end with two corresponding pins 0..

B represents the runner tube of tubular form, as shown in Fig. 5, mounted to slide upward and downward on the stick, and provided at its opposite ends with the vertical slots b, b, to admit the upper and lower pins respectively as the runner is moved upward and downward.

G 0 represent two double-ended spring .vated position.

catches applied in vertical positions to oppoe site sides of the runner tube and each secured at the middle firmly thereto by rivets c, as shown more particularly in Fig. 5. The ends of these springs are widened laterally, arranged to overlap the slots in the runner tube, bent outward at their ends-that they may ride upward on the pins and perforated to receive the pins, as shown in the several figures, so that when'the runner is carried to its uppermost position the upper ends of the spring catches will ride over the upper pins 0., and engage therewith, as shown in Figs. 1,

2 and 7, thus locking the runner in its ele- When, on the other hand, the runner is carried downward on the stick, the lower ends of the spring catches will in like manner ride over and engage the lower pins a.

. The sleeve D comprises two inner half shells d, d curved to fit the runner tube B, and outer cylindrical shell 61, and intermediate filling pieces 61 these parts being all riveted together as shownin Fig. 9, these parts and the runner tube B forming the complete runner. The inner shells d, d,are each somewhat less than a half-cylinder, so that when placed upon the runner tube open spaces (1 d are left between them at opposite sides to receive the body portions of the springs O, 0. They are each provided at both ends 'with circumferential ribs or collars e rounded off at the edges, as shown in Figs. 6 and 8 to enable them to pass freely under the widened ends of the spring catches to lift the latter off the pins 0:, a with a cam or wedging action.

The sleeve D is coupled with the runner tube B by means of a pin or stud e projecting o inwardly from one of the shells (1 into a longitudinal slot 6 in the runner (see Figs. 5, 7 and 8) said slot being of such length as to permit the requisite independent movement of the sleeve, the purpose of which will pres- 5 ently appear.

The shells d, d, are longer than the springs C, the difference in length being substantially equal to the length of the slot 6 Thus, when the sleeve is moved in either direction IOQ to the limit of its movement relatively to the runner tube, the collar e at one end will be beyond the ends of the springs C, so that the latter may lie at that end in their normal or holding positions, but the collar at the other end will be under the spring arms at that end and will hold them out in inoperative position, as is clearly shown in Figs. 2, 3 and 4.

The operation is as follows: The umbrella being down, or folded, and the parts in the position indicated in Fig. 1, when it is desired to raise or open it, the sleeve D is grasped and moved forward to the limit of its movement on the runner tube, the extent of this movement being determined by the length of the slot e This movement will carry the collars e at the upper end out from under the upper arms of the springs G, and permit the same to spring inward to their normal positions. The same movement will carry the collar e at the lower end under the lower spring arms and will lift the latter out of engagement with the pins a. As soon as the springs are lifted from the pins, the runner tube, sleeve, and springs will move forward together. When the bent ends of the upper spring arms strike the pins a, they ride up thereon, until the perforations therein are opposite the pins, when the springs snap down and engage the pins and hold the runnor in its elevated position. The parts are then in the condition represented in Fig. 2. To lower the umbrella the sleeve is grasped and pulled down. The initial movement brings the parts to the relative position shown in Fig. 3, with the upper collar e under the upper spring arms, the latter disengaged from the pins 01., the lower collar e beyond or below the ends of the lower springs and the latter lying flat in their normal positions. The continued movement of the sleeve carries the runner down and closes the umbrella, the lower spring arms engaging the pins a, the operation being identical with that of the upper spring arms in opening the umbrella.

Having thus described my invention, I claim- 1. In an umbrella runner, the combination of the runner-tube, the spring catch firmly secured thereto and having its end bent or curved outward, and the encircling longitudinally-movable and non-rotatable sleeve provided with a cam adapted to pass under, and lift, the end of the spring catch.

2. The combination with the stick or handle of an umbrella provided with upper and lower projecting pins, and with the runner mounted thereon, of the double-ended spring catch rigidly attached to the runner tube and having its ends perforated to receive and engage said pins, and the surrounding sleeve having limited independent movement on the runner and having at each end cams adapted to pass under, and lift, the ends of said catches to disengage them from the pins.

3. The combination with the stick or handle of an umbrella provided with upper and lower projecting pins, and with the runner mounted thereon, of the double ended spring catch rigidly attached to the runner tube'and having its ends curved outward to adapt them to ride up on the pins, and perforated to receive and engage the same, and the surrounding sleeve having a limited longitudinal movement independently of the runner, and having at each end cams adapted to pass under, and lift, said catches out ofengagement with the pins.

4. The combination with the stick or handle of an umbrella provided with upper and lower projecting pins, and with the runner mounted thereon, of the double-ended spring catch rigidly attached to the runner tube and having its ends curved outward to adapt them to ride up on the pins, and perforated to re- ,ceive and engage the same, and having the laterally projecting wings at the free ends, in combination with the surrounding sleeve havin g limited longitudinal movement independently of the runner and having at its ends cams adapted to pass under the lateral wings of the catch and lift the latter.

In testimony whereof I hereunto set my hand, this 2d day of January, 1891, in the presence of two attesting witnesses.

HENRY C. SWAN.
