IMPROVEMENT IN UMBRELLAS- Specification forming part of Letters Patent No. 178,068, dated May 30, 1876; application filed i r March 9, 1876. I

To all whom it may concern Be it known that we, GEORGE LIEB and CHARLES LIEB, of the city, county, and State ful Improvement in Umbrellas and Parasols;

the accompanying drawing, in which' Figure 1 represents a horizontal section in the planes: m, Fig. 2. Fig. 2 is a vertical section. Fig. 3 isa transverse section of one of 'theribs, showing its connection with the stretehjerr Similar letters indicate corresponding parts. This invention consists in combining with of an umbrella or parasol a metal collar, which is cast in. a mold into whichv the eyes of the stretchersor ribs are placed so that the fluid metal when poured into said mold will run through said eyes,

and when the metal has set, the required hinge-joint connection between the stretcher and the runner and between theribs and the he adot' the frameis produced without requir ing any further'labor; also, in a joint between the stretcher andrib ofan umbrella or parasol,

produced by casting on the rib a block of the stretcher projects, so that a portion of the 'metal in being cast runs through the eye of the stretcher, and when the metal has set it adheres firmly to therib, while at the same time the desired-hinge-jointis produced.

In the drawing, the letter A designates the runner of an umbrella or parasol, and Bis the head of the frame, which is composed of said runner and head, and of the ribs 0 and stretcherpD. The. connection between the stretchers and the runneriseffected by cast ing on the runner acollar, E, by means of a mold, into which the eyes a of the stretchers are placed before the metal is poured in;

The fluid-metal on being poured into the moldflows through the eyes a and forms pivots on which, after the metal has set, the

stretcher-s swing, the collar being provided with recesses b to allow the stretchers to close up against the'stick; i

The joints between the ribs 0 and the head B are made inthesame manner as the joints it may be cast without such ferrule and fats tened to the stick in any desirable manner.

The joints between the stretchers and the ribs are produced by casting in each of the ribs a block, d, of tin or other suitable metal by means of a mold, into which the eye 6 of the corresponding stretcher is placed, and as ,the fluid metal is poured into the mold it flows'through saideye, and when the metal has set a pivot is formed, on which the stretcher swings.

By following this method of producing the;

various joints, we are enabled to save much labor. The ribs and s'tretchersoan be made of round wires, the ends of which can be readily bent to form the required eyes, but

said eyes may be produced in any other (1e; sirable manner, either by flattening the ends of the wires and punching holes through these flat-ends, or by attaching to theends of thestretchers and ribs separate flat pieces of sheet metal; metal in a mold, into-which thelouter eye of What we claim as new, and desire to secure byLetters Patent, is-

pivots, on which said stretchers and ribs swing, substantially as set forth.

2. 1n ajoint between the stretcher and the rib of an umbrella, 'the combination of a stretcher, having an ,eye at its end, witha blockwhich is cast-on therib and ontheeye' of the stretcher,- so as to form a pivot extend- 9 ing through the said eye, substantiallyas de: scribed. l

In testimony that we claim the foregoing we.

have hereun'toset our hands andseals this 8th day of March, 1876.
