AUGUST MALMROS, OF HELSINGBORG, SWEDEN.

UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 257,354, dated May 2, 1882. i

' I Application filed November 28, 1881. (No model.)

To all whom it may concern Be it known that I, AUGUST MALMROS, a subject of the King of Sweden, residing at Helsingborg, in the Kingdom of Sweden, have invented certain new and useful Improvements in Umbrellas; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 represents a portion of one of the hinged ribs, with its brace, of my improved umbrella. Fig. 2 is a view of the same parts, showing the brace and its sliding sleeve adjusted to permit of the folding or doubling of the hinged rib. Fig. 3 represents the same parts with the rib in its doubled position. Fig. 4. shows the position of the parts for locking the folded rib in its doubled position and doubling the braces upon the doubled rib; and Fig. 5 represents the umbrella-frame in its extended or unfolded position.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of umbrellas or parasols in which the ribs may be folded or doubled upon themselves, so as to fold or double the cover when the umbrella is not in use; and it consists in the detailed construction and combination of parts of the frame, as hereinafter more fully described and claimed.

The stick A of my improved umbrella is made in sections, which are either hinged together or connected by thimbles in the manner well understood. The ribs are made in two parts, a and b, which are jointed by the hinge c,- and the upper part, a, is hinged in a ring or ferrule, B, near the top of the stick, in the usual manner. Both parts of the rib a and b are made of sheet metal and concaved on the under side.

(I is a portion of the brace appropriate to the rib. The lower end of the brace is hinged in a sliding sleeve or runner, G, which encompasses the stick, as usual, and to the upper part is hinged a small sleeve or thimble, f, which slides upon the top part, a, of the rib and forms the connection between the brace and rib. The part b of the latter has an elongation or arm, 9, projecting in the direction of its length, in the outer end of which is hinged a thin metal rod or wire, it, which rests in the concavity of the upper part, a, of the rib and terminates in a small hook or catch, it. The cover (not shown in the drawings) is stitched to the ribs a b in the usual manner.

When the several parts of the jointed rib and brace are in the position shown in Fig. 1 and in Fig. 5, the thimble f is pushed down over the projecting arm 9 of part b of the rib, thus locking the parts a and btogetherin their extended position, or the proper position of the rib for opening or unfolding the umbrella. In this position the tension of the cover, stretched upon the ribs, operates to draw sleeve f down over'arm g a little beyond the line represented by the brace 01 upon the rib a b in opening the umbrella, and thus operates to further interlock the parts and make the jointed sections a and b of the rib practically one rigid piece.

When it is desired to close and fold the umbrella, thimble f is released from arm gby pushing the sliding sleeve 0, to which the lower end of the brace is hinged, a short distance up upon the stick, the umbrella having first been closed, with its ribs resting against the stick. The sliding of thimble f upon part a will be stopped by the hook h, as shown in Fig. 2, which permits of the folding or doubling of b upon a, (the cover being doubled with the doubling of the ribs,) as shown in Fig. 3. The runner 0, upon which the braces are hinged, is now again drawn in a downward direction upon the stick until thimble f slides over the lower hinged end of rod h, after which it (the runner) is again pushed up under the rib-ferrule 13 at the top of the stick, when the several parts will be in juxtaposition, as shown in Fig. 4. The stick A is then folded or taken apart, and the folding of the umbrella is complete. To open out or unfold the umbrella this operation is, of course, simply reversed.

It is obvious that my improvement is not limited to umbrellas, but is applicable, also, and with like advantage, to sunshades or parasols.

I am aware that it is not new to construct umbrella-fram es with afoldin g brace or stretcher,in connection with a link and spring operating to hold the umbrella open or closed Withthe outer end of arm g, sliding sleeve or thinnout the aid of catches; but this is not what I ble f, and brace or stretcher d, hinged at its claim as myinvention. Nor do I elaim,broadouter end in said thimble, the whole constructr 5 ly, an umbrella-frame having jointed and folded and combined to operate substantially in 5 ing ribs; but the manner and for the purpose herein shown What I claim as my improvement, and deand described. sire to secure by Letters Patent of the United In testimony whereof I have hereto affixed States, is my signature in presence of two witnesses.

In an umbrella-frame, the combination of AUGUST MALMROS. 10 the folding ribs a I), provided with the joint or Witnesses:
