ARTHUR SYDENHAM, OF NEBRASKA CITY, NEBRASKA.

UMBRELLA AND PARASOL.

SPECIFICATION forming part of Letters Patent No. 341,862, dated May 11, 18186.

(No model.)

To all whom it may concern:

Be it known that I, ARTHUR SYDENHAM, of Nebraska City, in the county of Otoe, in the State of Nebraska, have invented a new and useful Improvement in Umbrellas and Parasols, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

This invention relates to improvements in umbrella and parasol frames; and it consists in improving the runner and fixed ring,

and also the ribs and theirjoint-connections, as will be fully understood from the following description, when taken in connection with the annexed drawings, in which- Figure 1 is a view of a portion of an umbrellastick having myimprovements applied to it. Fig. 2 is a perspective view of the improved runner. Fig. 3 is a similar view of the fixed connecting-ring. Fig. 4 is aview of one of the ribs, showing its broad coiled eyebearing. Fig. 5 is a detail of the same. Fig. (5 is a central section through the runner enlarged.

Referring to the annexed drawings by letters, A designates part of the umbrellastick, and B the fixed ring, having its sleeve secured in a suitable manner to the stick near one extremity, and connected to. it are the upper hooked ends of the ribs E, as shown in Fig. 1. The hooked ends of the ribs are first formed by spreading the metal and bending it so as to leave broad fiat hooks, which are passed through apertures in the web of the fixed ring B, and then firmly closed, thus forming articulating fastenings, which will not rock or twist laterally.

About midway ot the length of the ribs E, I form eyes, b, by coiling the rib several times and thereby forming broad eye-bearings and joint-connections for the hooks b on the outer ends of the braces C. By thus connecting the in the web of the runner-D, asshown in Fig. 1.

It is well known that hitherto the joints forming the connections between the ribs and fixed ring and the braces and runner of an umbrella are the weakest points and first to give way. To overcome this objection by a cheap and simple means is the main object of my invention.

The fixed ring B and the runner D are, or may be, constructed exactly alike. Therefore a description of one will give a clear understanding of the other. I take a fiat ring, and by suitable means I l'orm notches in its periphery equidistant from each other, leaving intermediate tongues or divisions, c, which have grooved seatsf in their ends. I then prepare a ring, g, of suitable diameter and gage of round wire to afford the requisite strength. This ring is fitted into the grooves or seats f, in the ends of the divisions e, and permanently fixed thereto by soldering, brazing, or otherwise casting it and the flat notched ring together. By these means I re-enforce the periphery of the fixed ring and the runner, and form round bearings'for the broad flat hooks on the ribs and braces, and thus afford very strong and durable connections at these joints.

I am aware thatit is not new in umbrellaframes to form ribs with integral eyes to receive the outer ends of the braces, nor is it broadly new to form a runner and a fixed ring with an annular series of apertures to receive the hooked ends of the braces and ribs. I therefore do not claim either of these constructions, broadly; but

\Vhat I do claim is 1. An umbrella brace or rib attachment consisting of a flat ring having notches in its periphery, leaving tongues or divisions 0, pro vided with grooved seats in their ends, in combination with a re-enforcing ring secured in said seats, substantially as and for the purposes described.

2. Au umbrella-frame consisting of a staff, A, the runner, and fixed crown-piece, each having a ring secured in seats formed in its periphery, divisions e, the ribs E, attached to the ring of the crown-piece by flat hooks, and having broad eyes b, formed by coiling the ribs, and the braces 0, connected to said coils and to the ring of the runner by broad hooks, substantially in the manner and for the purposes described.
