IMPROVEMENT IN STOPS FOR UMBRELLA-RUNNERS.

The Schedule referred to in theseA Letters Patent and making part of the same.

To all whom yit muy concern Be it known that l, Josuru W lueur, oi' Philadelplna, Pennsylvania, have invented au 1n1proved-Stop for Unibrella-Ruuuers; and I do hereby declare the following to be a ifull, clear, and exact description of the.` same.

My invention consists ofl a stop for umbrella-runners -which is secured to, passes through, and projects from opposite sides oi' the uniln'ella-stick, substantially as described hereafter, so as to aiiord greater V'security against displacement than the ordimuy staple, and so that the runner mav have two projections, instead oi' one only, to bear against.

In order to enable others skilled in the art to make andl apply my invention, I will now proceed to describe a mode of constructing and using the salue, reference being had to the accompanying drawng which iornxs a part of this'speciiication, and in which- Y liigiu'e l is a View of a portion of an umbrella-stick, with the runner, and my improved stop for the saine.

Figure 2 shows another form of the stop.

Figure 3 is an enlarged sectional view of a portion 0i' iig. l.

Figures 4 and 5, views of the stop detached.

Figure (,"a view of au ordinary stop. .y

Similar letters refer to similar parts throughout the several views.

The stop in common use is an ordinary wire staple, ig. (j, which is driven into one side ofan umbrellastick, to prevent the runner from sliding upon the stick beyond a certain point when theumbrella is opened.

The runner A, to which the trame of the umbrella i is'attached, and the spring-catch B, against which it bears when the fraaie is extended, are shown in iig. 1. But for this stop, the runner, when the umbrella is opened and exposed to sudden gusts of wind, would slide up the stick, and permit the ribs to become still more extended, until forced out of shape, and the covering turned inside out.

Even with the stop,.as ordinarily constructed, this accident is of frequent occur1'ence,ibrtl1e staple being gene jally driven but a short distance Vinto the stick, and

on one side only of the' saine, is easily detached by the runner. '4

Various attempts have been made to remedy this defect, one of which is to add to the number of ribs in the frame of the umbrella, in order to increase its power of resistance to-the wind, and thus diminish the tendency oi' the runner to slide upwards, and enable the stop to hold it. This plan, however, adds to the weight aud price oi' the umbrella, and has not been generally adopted.

My improved stop is niade in the form of a sta-ple, of stout iron wire, and has legs, a a', of' different lengths, and a shoulder, (12, which bears against and penetrates a short distance into one side of the umbrella-stick,

when the ends are driven in. (See l, 3, and 4.) These ends, however, penetrate entirely through the stick, the longer one projecting beyond it to about the saine distance as the bend af, on=thc opposite side, while the shorter end projects but slightly, and is riveted so as toprevent the staple i'roni being witlulrawn.

lhis riveting oi' the shorter end a is facilitated by the square shoulder 2,'whieh is placed upon a block or anvil, and atibrds an unyieldiug support during the rivetillg-proeess.

Af staple thus formed, and secured to the umbrellastick, cannot be fm'eed out by pressure upon either of its projecting ends, and it forms an eiictual stop for the ruimer, the latter having two unyielding points to bear against, instead oi' one, as heretoibre.

It soule-times necessary to remove the ruimer- 'stop in i'epaii'ingtlic umbrella. This may be readily done by severing it ou the line y, iig. 3, and then withdrawing the pieces separately.

Although, for simplicity and cheapness, I prefer a stop ot' iron wire ibrmed as above described, various modiiications otlny invention will suggest themselves. For instance, a staple can he stamped Lout of sheetbrass, as seen in iigs. 2 and 5, the short end, al, being in this case-bent abruptly at the end, instead of riveted I claim as my invention, and desire to 'secure by Letters Patentl A stop for umbrella-ruimers, consisting of a staple, having legs a al, of different lengths, and a shoulder, a?, substantially as described. I

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses. v
