page_text: I ARTHUR SYDENHAM of Nebraska City, in the County of Otoe in the State
of Nebraska, one of the United States of America Gunsmith, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
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 their
joint-connections, as will be fully understood from the following description, when
taken in connection with the annexed drawings, in which-

applied to it.

through the runner enlarged.
Fig. 3 is a similar view of
the ribs, showing its broad
Fig. 6 is a central section
Referring to the annexed drawings by letters, A designates part of the umbrella
stick, 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 flat hooks, which are passed
through apertures in the web of the fixed ring B, and then firmly closed, thus
forming articulated fastenings, which will not rock or twist laterally.
About midway of 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 on the outer ends of the braces C. By thus connecting the braces and
ribs I prevent lateral twist at their points of articulation with each other. The
inner ends of the braces C are formed with flat hooks, like the upper ends of the
ribs E, which are hooked through the apertures a a, in the web of the runner D,
as shown 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

page_text: a flat ring, and by suitable means I form notches in its periphery equidistant from
each other, leaving intermediate tongues or divisions, e, which have grooved seats f
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 that it is not new in umbrella-frames 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.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1st. An umbrella brace or rib attachment consisting of a flat ring having notches
in its periphery, leaving tongues or divisions e, provided with grooved seats in their
ends, in combination with a re-enforcing ring secured in said seats, substantially as
and for the purposes described.
2nd. An 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 C, connected to said coils and to
the ring of the runner by broad hooks, substantially in the manner and for the
purposes described.
