FREDERICK REICHHOLD, OF NEW YORK, N. Y.

FRAME FOR UMBRELLAS AND PARASOLS.

Specification of Letters Patent No.

To all whom 'it may concern:

Be it known that I, FREDERICK REIoHHoLD, of the city, county, and State of New York, have invented a new and useful Improvement in Frames for Parasols and Umbrellas; and I do hereby declare that the fol-` lowing is a full, clear, and exact description `of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure l, is a general view of the frame; Fig. 2, a magnified view of the rib and the stretcher.

Similar lettersv of reference indicate corresponding parts in these figures.

To enable others skilled in the art, to make and use my invention I will proceed to describe it.

To construct the rib D, I t-ake a thin metallic wire D, and wind or coil another thin metallic wire D around the same. The interior wire D, is to be somewhat shorter than the rib and the coils of the exterior' wire D', are to be continued on its upper part beyond the length of the interior wire. On the point O where the rib is to be connected with the stretcher the coils of the exterior wire D are so enlarged that a hole loop or eye O is formed in which the stretcher may be bent hooked or fastened. The stretcher E is also formed of two wires E and E, the latter being coiled around the former and extending its coils beyond bot-h ends of the exterior wire; the upper coils are then bent, hooked or fastened on or into the loop or eye O formed by the exterior wire of the rib D D as shown in Fig. 2. The lower coils of the stretcher are fastened in similar manner to the runner wire C, and the upper coils of the rib are fastened in similar manner to the notcher B, on the stick A.

The drawing represents the attachment made by a single coiled wire. Should this 22,033, dated November 9, 1858.

be found too weak, the connection may be effected by doubling the wire on and near the points, where the attachment is to be made.

I deem it proper to`state, that I prefer the use of steel wire for making these frames to any other metallic wire. The characteristic feature of such frames consists in the longitudinal elasticity imparted to the rib and the stretcher. It is found that many parasols `and umbrellas of the usual construction are defective in consequence of the want of longitudinal elasticity of the rib and the stretcher. Suddenly opening of parasols and umbrellas will generally split or tear .the silk or other covering on or near the ribs; and exposing them to the action of wind will generally break them. Attempts have been made to form aconnection between the rib and the stretcher by using stout wire and by coiling the same into loops at the proper places, but coiling stout wire makes the same brittle, in such a manner that the stretchers break near the middle loop. All these and other defects are avoided in my construction.

The interior and the exterior wire being each very thin, the quantity of metal required for my construction is not greater than that of the usual wire frames.

What I claim as new and desire to secure by Letters Patent is:

Making the stretcher and the rib of two wires each, forming the loops or eyes of the rib by coils of the exterior wire and attaching the stretcher to the rib; the rib to the notcher, and the stretcher to the runner, by coils or hooks of the exterior wire; all in the manner and for the purpose substantially as described.

New York September 25, 1858. v

FREDERICK REICHHOLD.
