IMPROVEMENT lN-TIPS FOR UIVIBRELLAS AND PARASOLS.

Specification forming part of Letters Patent No. 36,26l, dated August 19, 1862.

To all whom t may concern.-

Be it known that I, RICHARD A. STEATTON, of Philadelphia, Pennsylvania, have invented an Improvement in Tips for Umbrellasand Parasols; and I do hereby declare the follow ing to be a full, clear, and exact description of the same, reference being hadA to the accompanying drawings,and to the letters of reference marked thereon.

In manufacturing the steel ribs of umbrellas and parasols it has been usual to dispense with the tips such as are used on cane or whalebone ribs.

My invention consists of metal tips cast to the steel ribs of umbrellas and parasols, as describedhereinafter, so as to avoid the sharp,eX posed, and otherwise objectionable ends of the ribs as heretofore constructed.

In order to enable others to make my invention, I will now proceed to describe the manner of carrying it into effect.

On reference tothe accompanying drawings, which form a part of this specification, Figure 1 represents the end of a rib of an umbrella or parasol with the improved tip; Fig. 2, a dia gram illustrating the manner of forming the tip on the rib.

A represents the end of the steel-wire rib of an umbrella, and B the tip, which is made of type-metal, or any metal or alloy which will melt at a moderate heat and which is sufficiently durable wheny cool, an eye, a, being formed'v on the tip for the reception of the threads, by means of which the cover of the umbrella is secured to the tips.

In order to secure the tip to the rib, I make use of the well-known type-casting machine, an outline of which is presented in Fig. 2.

C is the vessel containing the metal or alloy of which the tip has to be formed, D the chamber containing the ignited fuel for maintaining the metal in a molten state, and E the chimney. Adjacent to the vessel C are situated the upper and lower dies, G and G', which inclose a space of the form of a tip. After the end of the steel wire has been introduced between the dies, as seen in Fig. 2, the lever His depressed, so as to cause the plungerl to force a portion of the molten nietalinto the space inclosed by the dies Gand G', after which the dies are taken apart and the rod, with the desired tip adhering closely thereto, removed. It should'be understood that the end of th wire is perforated or indented prior to its introduction between the dies, so that the tip may retain its place on the rib, or the latter may be tinnedr atA the point where the` tip has to be secured7 so as to insure the close adhesion of the latter to the Wire. The eye is formed in the dies at the time of casting the tip, or
