UMBRELLA-RUNNER RETAINER.

SPECIFICATION forming part of Letters Patent No. 580,786, dated April 13, 1897. Application filed September 1, 1896. Serial No. 604,540. (No model.)

- Jersey, have invented a certain new and useful Improvement in Umbrella-Runner Retainers, of which the following is a specification. My invention relates to a new and useful improvement in umbrella-runner retainers,

. that the staff is hollow, as here shown.

and has for its object to provide a device of this description which will be exceedingly cheap in construction and simple in application and whenin use will be exceedingly durable, and should it at any time become broken or otherwise rendered useless it may be replaced by the substitution of another retainer without in any way injuring the staff.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth, and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in whicl1- Figure l is an elevation of a portion of an umbrella-staff having a section thereof broken away so as to illustrate the application of my improved retainer thereto; Fig. 2, a similar view showing the manner of applying the retainer to the staff, and Fig. 3 a detailed perspective of the retainer.

In carrying out my invention I form the retainer in a single piece by stamping it from sheet metal in the usual manner, and this retainer consists of the latch A, the bow B, and the nose 0, and is secured within the staff D by the latter having a longitudinal slot E formed therein and a hole formed upon the opposite side thereof, it being understood To insert the retainer within the staff, the bow B is passed through the slot and forced downward until the shoulder G of the latch comes in contact with the lower end of the slot, at which point the latch will occupy the position shown in Fig. 1, and at the same time the nose 0 will have entered the hole F by coming in alinement therewith, the spring action of the bow causing said nose to remain in engagement with the hole F. Now it is obvious that the retainer may be depressed, for the purpose of permitting the runner to pass thereover, by exerting sufiicient force upon the latch to compress the bow, and yet when this pressure is released from the latch it will again spring outward, serving the purpose of retaining the runner against down ward movement, as will be understood.

While I have shown my improvement as especially adapted for use in connection with metal staffs, it is obvious that it might also be adapted for use in connection with wooden stafis by placing a metal housing thereon having the slot and hole formed therein for the reception of the latch and nose.

One of the principal advantages of my improvement is that it is made from a single piece of metal and is produced by one operation of a press, which press may be fitted to produce the retainers automatically, thus making their cost insignificant, and the retainers are so readily attached to the staff as to require almost no labor, since it is only necessary to pass the bow through the slot and exert a slight pressure thereon to bring it into position. Another advantage of my improvement is that should at-any time the retainer become useless by breakage or otherwise it may be quickly Withdrawn by forcing the nose from without the hole and withdrawing the bow through the slot, after which another retainer may be substituted therefor, and this without injury to the staff in any manner.

While I prefer to form-the retainer of sheet metal, it is obvious that it might be formed of a single piece of wire so. bent as to produce the bow, latch, and nose, and for some purposes this design would be serviceable.

It is to be noted that the hole F is diametrically opposite the lower end of the slot E, and this is of importance in the action of my improvement, since it serves better to hold the retainer in place and also permits the bow B to have a freer spring action than would otherwise be the case.

Having thus fully described this invention, what is claimed as new and useful is- V In a device of the character described, the combination of the hollow staff D having therein a longitudinal slot E and a hole F diametrically opposite the lower end of the slot, a spring-bow Within the staff, a latch A on one end of the bowprojectingthrough the slot E and a nose 0 on the other end of the boW projecting through the hole F to the outside so as to be adapted to be forced out of position from the outside, said bow being adapted to force the latch and nose apart whereby they are held in their relative posi- 1o tions, as and for the purpose described.

In testimony whereof I havehereunto affixed my signature in the presence of tWo subscribing Witnesses.
