I Application led April 30, 1910. -Seri'al No. 558,580.

To all fwhafrnfit may. concert/m1 v Be it known that I, lBERT C.j EDKIN, a citizen of the United States, residing at Erie,in

in certain improvements therein as will be ,the county of Erie and State of Pennsylvahereinafter fully described and pointed out f in the claims.

' The invention is particularly adapted Afor casting thinstrips of suchmetals as contract greatlyin cooling, as compared with the cohesive quality of the metal inv a fluid or semi-fluidstate.

I have utilized the invention in casting -brakeshoes'rformed of a metal made np of 'copper land lead' of about equal parts.` These ,ange from tento eighteen inches long, and in'A width from one to six inches, and in thickness from one-eighth, to livesixteenths of an inch. In casting these, great diliiculty has been experienced by reason ofthe fact that the metal in cooling contracts, and this contracting is so localized 'or cumulated at some -one point alongl the metal that the finished. casting separates or forms two parts. I have obviated this difficulty by arranging in the mold, rpreferably on one face of the mold, a wire mesh, then, pouring the Huid metal into the mold. The wire mesh engaging the metal: prevents theI localizing of the construction and thus the separation of the metal.v In this 'way I find it entirely A' feasible to cast metals of this kind, ina s ingle length or ten toV eighteenv inches, suitable jfor automobile brake shoes and thelike.

I prefer `to arrange the wire mesh diagonally to the length of the metal strip. This adds to its iexibility in following thecontraction of the metal. y

' In the accempanyingl drawings I `have shown the method of arranging the mesh in the mold. y

Figure 1 shows a plan view of'one portio of themold; Fig. 2 a central section through the mold.

1 marks the draw; Q'the cope; 3 the mold; 4 the metal strip, and 5 the wire-gauze.

In practice, the cavity is formed in oneor the other parts of `the moldl so that the wire gauze may be laid on one face of` the mold, and extend beyond' the faces of the mold. The mold parts, when they are placed together, hold the wire mesh in position along one face of the mold cavity, so that in the finished article the wire mesh is on one face of the metal Strip.

Patented Mar. 2s, 1911.:

In the drawings but a fragment of the metal strip is shown, it being broken off .at one end.

The method is useful,where the cross section is such relatively' to the length as .to result in the separationor make it diflicult, to

prevent the separation, of the casting during cooling.

-What I claim as new is:

1. The art or process o f casting articles in .the form of thin strips and of a metal that contracts greatly in cooling as compared with its cohesive quality in a fluid or semi-Huid state, which consists in securing to the metal while in a molten state a reinforcing strip whereby the localizing of the contraction of the metall is prevented.

2. The art or process of casting articles in the form of thin 4strips and of a metal that contracts greatly in cooling as compared with its cohesive quality in a fluid or Semi-Huid state, which consists in embedding in the metal while in a molten state a reinforcing strip whereby the localizing of the contracf tion of the lmetal is prevented.

3. The art or process o f casting articles in the form of thinstrips and of a metal that contracts greatly in cooling as compared with its cohesive quality in a fluid or semi-fluid state, which consists in embedding a wire mesh in the metal forming the casting while A in the molten state whereby the locali'zing of the contraction of themetal is prevented.

4. The art orprocess of casting articles in the form of thin strips and of a metal that contracts greatly in cooling as compared with its cohesive quality in a fluid or semi-fluid state, which consists in embedding a wire mesh in the metal forming'the casting while in the molten state, whereby the localizing of the contraction of the metal is prevented,

said wire mesh being arranged with the wires thereof in a direction -diagonal to th length of the strip.

5. The method or process of forming thin strips of` metal which consists 1n forming a mold cavity, arranging a wire mesh thereon esence of1 two `subscribing With the edges of the Wire mesh of greater l my 'hand in the 'pr extent than the mold Cavity closing the mold I witnesses. cavt and holding. thewire mesh in )luce Y w n n :1t thgedges Aalong-erle)Surface of the rhor, A BEh u' EDKU" and introducing 2r molten metal to the mold `Witnesses: cavity. k 1- H.
