'l'o @ZZ whom, t may concern:

Be it known that I, MARTIN (113130K, a citt zen of the United States, and a resident of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Umbrella Frames, of which the following is a clear, full, and sufficient specification, reference being had to the drawings annexed.

My invention relates to the class of frames known as wireless frames. One of the chief objections to frames of this character made hitherto has been that the rib end could not be made to lie close up to the stick, eX- cept in those constructions where the slots opened at the larger end of the retainerpiece-that is, the piece that held or retained the enlarged ends of the ribs. The devices in which the retainer pieces did not have their slots so opening have hitherto had them open at the bottom and the lower end of the prongs between the slots, which held the enlarged ends of the ribs, had to lie at a distance from the stick sufficient to permit the enlarged end of the rib to be introduced be tween the ends of the prongs and the stick, and to complete the socket for the enlarged ends of the ribs a bushing was inserted between them and the stick. This necessarily increased the size of notch and made the umbrella larger there, and was hence objectionable in this respect. To avoid this objection and present such a construction as will permit the enlarged ends of the ribs to lie close up to the rod to strengthen, simplify, cheapen and enable the ribs to be readily inserted and removed are among the chief objects of my invention.

tion, on the Figure 1 is a side elevation of my invented device where the retainer is slipped down on the bushing, showing a rib inserted; and Fig. 2, one turned in position to be inserted in the notch shown in Fig. l. Fig. 3 is a vertical section of the device as shown in Fig. 1. Fig. t is an elevation of the bushing, on the left of the vertical line, in section. Fig. 5 is a plan view of same. Fig. 6 is a side elevaleft of the vertical line, in section of the retainer-piece. Fig. 7 is a plan view of the same. Fig. 8 is a side elevation, partly in section, of a form of my invented device l differing slightly from those shown in Figs. l and 3, in which the retainer-piece and bushing are slid over each other until the lower end of the bushing forms the abutment for the end of the rib. Fig. 9 is a vertical section of the device shown in'Figs. 1 and 2 with the retainer-piece slid over the bushing into the relative positions they will occupy when the frame is ready for use. Fig. 10 is a side elevation, with the lefth`and side in section, of a modification of the retainer-piece. Fig. 11 is a top view of the device shown in Fig. 10. In my invented device the retaining ends F of the ribs D are held in a socket formed by the stick, (or if this is of wood a slight wrapping may be put around it to'take the wear,) the retainer-piece C, and the bottom of the bushing B. This construction brings the rib ends closer to the stick than any prior construction. Describing now the best form or" which I am aware of making this construction, around the rod A is placed the bushing B, and around the bushing B is the retainerpiece, (lettered as a whole 0,) consisting of the support c, that surrounds the stick, and the prongs g g,which extend downward therefrom (the direction downward being considered in this specification as toward the handie) and having their lower ends projecting inward toward the rod and lying adjacent thereto. Between these prongs are the slots G, that are of greater length than width. The bushing and retainer-piece are movable relatively to each other in the direction of the length of the stick sufficiently at least to allow them to change their relative positions from that shown in Fig. 3 to that shown in Fig. 9, in which latter gure it will be seen that the retainer-piece is pushed farther over the bushing than in the former. When in this latter position,vz., that shown in Fig. 9--the lower end of the bushing B forms an abut ment for the end F of the rib D, while the prongs g g and the stick form the rest of the socket in which the end F is held. The bushing B and the retainer-piece O can be fastened together and to the stick by any convenient meansfor instance, by pin 3. The ends F of the ribs D can be inserted in position in the manner shown in Figs. 1 and 2. The rib D can be turned or twisted, as shown IOO 1n Fig. 2, so that the enlarged end piece F can pass through the slot G, and it will spring back into position, as shown in Fig. l, the contracted waist E being able to turn in the slot G. The retainer-piece C and the bushing B are then moved relatively to each other n so as to bring vthe lower end of the bushing close to the upper side of the enlarged end F of the rib (see Fig. 9) and cause it to form an abutment therefor and prevent it from being 'removed from the notch. The bushing and retainer-piece can then be suitably secured together.

It will be seen that by this construction a smallernotchby at least an eighth is made than had previously been made with-any retainer not opening at the larger end, and the objections to opening the retainer at the larger end are well known to practical umbrella-makers.

In Fig. 8 is shown a form of my invention in which the bushing B is formed of an extra tip that is slipped over the main urn-- brella-rod A.

In Figs. 10 and ll is shown a modification 0f the retainer which can be used where 0bjections are made to twisting the rib. In this form of my device, C is the retainerpiece, `in which are the slot G and the crossslot H. t

Having now described my invention, what I claim, and desire to secure by Letters Patent, is`

The combination with the stick of an umbrella or parasol, of a retainer-piece provided with prongs, each prongV having Vone end projecting inward and lying substantially adjacent to the stick, and with a support for said prongs, surrounding said stick; a bushing inserted between the said support and the f stick; ribs,provided with retaining ends, lying between said prongs and the stick; and an abutment for the retaining ends of the ribs, lying on the side of them opposite the ends of the prongs adjacent to the stick; substantially as described.

In witnessthat I claim the above as myin- `vention and desire the same to be patented to lne I have hereunto set my hand this 9th day of November, 1900.

I MARTIN C. BECK.
