Letters Patent N o. 99,950, dated February 15, 1870.

*dwf- IMPROVEMENT IN UMBRELLAS.

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

To all whom it-may concern:

Be it known that I, HORACE T. ROBBINs, of Boston, in the county of Sutolk, and State of Massachusetts, have invented a new and useful Improvement in Umbrella and Parasol-Frames; v and I do hereby devfrom the frame.

Figure 3 is a view of the same taken at right angles to that of tig. 2.

Figure 4 is a side view of the supports detached from the rib. V f

Figure 5 is an endview of the saine. Similar letters refer to like parts in the different drawings.

a is the handle. t the runner. c the notch-plate. d the ribs. c the stretchers. f the rib-joint plate. g the supports. lThe nature of my invention consists 'in providing umbrella and parasol-iiames with a device to prevent the breakage and annoyancearising from the ribs and stretchers interlapping and becoming tangled -With each other in opening them, thereby greatly taeilitating that operation. s

I construct my improved umbrella and parasolframes in any of the usual forms; but in order to obviate the trouble arising from the ribs and stretchers interlapping and tangling in the operation of opening them, I apply to the ribs supports g, which rest against the stretchers, and thereby hold the ribs in such a position as to keep the joints-where the stretchers are attached to the ribs slightly distended from the haudle when the umbrella is closed.

The elasticity of the ribs and stretchers allows th cover to be wrapped around them as compactly as it would be Without the supports, but as soon as the cover is unwound they resume their former position,

ready to expand at the slightest upward pressure on the runner.

I usually connect these supports to the ribs by pressure just below the rib-joint plate in the same way as that is attached. They may, however, be made ofthe saine piece with the rib-joint plate by extending the lower end of it sufficiently to rest against the stretchthe stretcher-s near the top to lie back against the ribs, or they may be attached to thestretchers near the ribjoint plate, or they may be applied to the stretchers lower down and rest against the handle, or they-may be applied to the upper part of the ribs and. rest against the handle.

I claim, in combination with4 the ribs or stretchers of an umbrella-frame, the stops orsnpports g, substantially as and for the purpose specified. l
