UNITE STATES PATENT OFFICE.

L. K. SELDEN, OF HADDAM, CONNECTICUT.

UMBRELLA.

Speccation of Letters Patent No. 23,503, dated April 5, 1859 To all whom tz' may concern:

Be it known that I, L. K. SELDEN, of Haddam, in the county ot Middlesex and State ci Connecticut, have invented a new and Improved Umbrella or Parasol, and I do hereby declare thatthe following is ai full, clear, and exact description of the same, reference being had to the annexed draw ings, making a part oitl this specification, in whichd Figure l, is an inverted plan view of my invention in an open or distended state. Fig. 2, is a section ci" ditto also in an open or distended state, taken in the line fc, m, Fig. l. Fig. 3, a side view of ditto in a closed state.

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

This invention consists in having the frame of the device formed of a series of expanding or jointed arms or bars, arranged as hereinafter fully shown and described, whereby an umbrella or parasol of ample dimensions is rendered capable of being lr'oided in a very small compass and also rendered extremely portable, and very strong and durable.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents what may be termed the rim of the umbrella or pa 1asol trame. This rim formed of a series ot metal arms or bars a, which are of equal length crossed in pairs and connected by pivots Z), slightly out of center so that the outer parts of the bars beyond the pivots will a little exceed the inner parts. The ends of the bars a, are connected together by pivots c, so as to Jr'orm a rim or annular frame for the cover.

B, represents a tube to which the rim A, is attached by three or more stretchers C, C, C. These stretchers are constructed on the same principle as the rim A, to wit, of a series of crossed bars or arms d', connected by pivots and having their ends connected by pivots c. The inner ends of the stretchers G, are attached to slides D, D, on the tube B.

E, is the cloth or covering of the umbrella or parasol. This covering is made in the usual way and of any of the materials used for such purpose, the edge of the covering being attached to the rim A.

The slide D, is allowed to work freely on the tube B, and is fitted and works between shoulders f, f, thereon. 4The slide D', is also allowed to work freely on the tube B, but it is attached by a pin g, to a rod F, which is iitted within the tube B, the pin g, passing through a slot L, in the tube B. The arms or bars a, and fz, are formed of metal and are all got out of equal dimensions. The rim A, tube B, with its rod F, and the stretchers form the frame of the device.

From the above description it will be seen that by grasping the tube B, and rod F, and moving the slides D, D, toward and from each other, that the arms a, a', will open and close and the frame be expanded or contracted or folded as may be desired. IVhen the slides D, D, are shoved toward each other the frame will be opened or distended as shown in Figs. l and 2, and when the slides are moved from eachother the frame will be folded or closed as shown in Fig. 3. 1When the frame is opened the arm or bars a, of the rim A, will assume nearly a horizontal position and it will be seen that the device will close in a very compact form and be extremely portable. The device also will be extremely durable, as the frame owing to its combination of bars, forms a net-work of great strength.

I would remark that if necessary, catches ,XX may be attached to the stretchers C, so that when the frame is distended or opened, the arms or bars a, may be kept distended or prevented from casually closing, see Fig. 2. These catches however may not be necessary.

I do not claim broadly an arrangement of arms or bars pivoted and connected together as shown, when viewed separately and irrespective of the adaptation herein described, :tor arms or bars thus connected have been used for various purposes; but,

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, as a new and improved article of manufacture is,

An umbrella or parasol having its frame constructed of a rim A, and stretchers C, formed of arms or bars a, a', pivoted and connected together as shown, in connection with the tube B, and rod F, arranged as described.
