SPECIFICATION forming part ofiLetters Patent No. 293,662, dated February 19, 1884.

Application led October 20, 1883. (No model.)

Be it known that I, HARVEY MILLER, of Cincinnati, Hamilton county, and State of Ohio, have invented a new and useful Improvement in Hinge-Tips, of which the follow" ing is a full, clear, and exact specification, reference being had to the accompanying drawings, forming part of this statement of invention, in Which- Figure l is a perspective view of my hingetip. Fig. 2 is a vertical section through my hinge-tip.l

Similar letters of Vreference inthe several ufigures of the drawings indicate the same parts.

My invention relates to hinge-tips forsafes, and may be used for any similar ornamental purpose.

The hinge'tips in general use are solid castings. My hinge-tip is cast about acement or other suitable substance that will withstand ar crushing pressure. My hinge-tip consists of a metal casting inclosing an interior solid form.

Preferably the form Ais made of cement. My hinge-tip is 'made as follows: An interior cement form is rst molded, a-pin is inserted into it, and it is then placed in a mold, and the metal is poured around it.

Reference being had to the drawings, C, Fig. 2, is the outer metal shell; B, the inte'- rior form, (made preferably of cement;) A, the hole in the shell C and the neck of said shell and -in the form B, made bythe pin inserted in the form B.

Among other advantages that my tip has over the ordinary solid tip are the following:

First. Lightness of weight and economy inI metal. l

Second. A large percentage of the solid tips is rejected on accountof blow-holes or airholes that form in their substance in casting. A hinge-tip is not salable until it is plated with nickel or some other bright metal, and

if a tiphaving air-holes in it is plated the solution is taken up by the holes, andA afterward .sweats out and destroys the plating. Tips made as I make them do not show these air-v holes. Y

Third. Solid tips are wrapped in paper for shipping and then packed together, and many of them are ruined by reason of knocking together in transit. My tip is shipped without They are held on pins inserted into Y the tips on racks.

wrappers.

Every one'is thus held apart from the others, and is free from danger arising from friction.

The advantage of my tip over a hollow tip is this: A hollow tip would be crushed by the tongs in screwing the tip into place. My tip, being lled Awith a non-crushable solid form, resists such pressure as would a solid.

metal tip.

Patent, is as follows:

As an article of manufacture, a l1inge-tip consisting of an outerl metal shell cast over and inclosing a pressure-resisting form, and having the screw cast hollow and integral therewith, substantially as described.

The foregoing specification of my invention signed by Inethis 17th day of October, A. D. 1883.
