' To all 'uuwmit may concern:

Be it known that I, OTHO V. Kmm'a citizen of the United States, residing at T0 ronto, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Mold Construction, of which the following is a full, clear, and exact. description, uch as'will en:

able others skilled'in the art to which il an pertains to make and use the same.

This invention relates to mnail structure and with respect to certain more speeific features, to a structure of this type which may he used in founding.

One ofthe objects of the invention is to provide a practieable and ellioient article of (his type which I may be mn'nufaotiued quickly and cheaply.

Another oh'ectis to provide a; durable article of the" type described with a. mini-1 mum-use of metal. r

Another object is to provide an article of the type described" which may he mentifactored in large quantities by simple and comparatively inexpensive machinery.

()therfohjeets'will he in part obvious in part poinredout hereinafter. I The invention accordingly consists in the' features 'of 'eonsiruction combinations o'l! eleinenis and 'arifangemehlof mrls Wlllil'l will be exemplified in "she oonsrruct-ion hen inaf'ter se't forth, and the scope of he nppli cation of'whiuh will be indicated 'in the following claims.

In the drawin s wnerein is shown one of the various possilile embodiments of the in venlion, Figure 1 represents a blank from which the finished article may be inside; Fig.2 represents rhe partially compleled article; Fig. 3 represents the co nplee article; Fig. 4 is a planview looking from above in Fig. 3fand Fig. 5 is a cross sectional' view showing the device applied "to a molding surface.

In Fig. l of the drawing shown blank of thin sheet metal which may of any and desired eomoosition for oxam' le Cl'lfif-J tin plate, or the like, from which the nail structure isio be made. This blank is preferably in the form of rectangular oblong thin strip having oppositely disposed longitudinal edges 1 and 2 and oppositely 90586 ends 3 and 4. y

I In manufacturing the nail siructure, the blank may be formed into any desired shape.

in Fig. 3.

As shown in Fig. 2 it is preferabl rolled into a substantially cylindricalfiubn e1 fdrffi with the longitudinal edges 1 and Qediii cent one another and spaced :1 short ammo apart. These edges may be brought into desired degree of proximity; Kilt-ii at!" r ling or bending the thin sheet-into t cylindrical form; as shown in Fig. 2 h-" heed portion may be made upon the en-dof the eylinder by spreading, bending 0r crimping the metal, thus formlng an inte'gra-l surface or head 5. at substantially right'ai'igles to the remainder of the cylinder which conj stitotes the hollow body portion 6',- as shown Aifter bending or otherwise dis-v posing the end 3 of Lhe blank at right angle;

to the body portion, thishezrdm'ay' be con veniently shaped into substantially annular form as shown In Fig. 4: by plac'mg the sur face 5 in adie and preferably bringing the edges 1 and '2, which are coritii'nmtions of f the edges 1 and 2 of the body portion, into anyv deeired c'legree of proximity.

As heretofore ind icatedjhe nail structure described is particularly "lad-a ted for foundry Work and is shown in 'fig. 5 ashere employed. 7. designnlese' dorewhioh is a'dapfed to he held in position-Within the mold and spaced from the; sand The sand as shown is so shaped Hml ii prori'rles fil fln't 'moldi'ng Surface 9, along which the metal is adapted to How and a depressed surfa-ee 10 providing corners .11.; The nails shown are nda pfed to he placed with i'lieir heads 5 oulerl-nost along the Bill surf-are 9; l hey are also shown in he dern'essed, portion E0 and at the corners or iillels ll. llhen-the nails;

. are thus placed they are axllzrpted-jto subsizom itiolly prevent the dislodgment of portions 0? tho sand when hot meta-l flows thereover and are (hos adapted lo preserve the a, that it may.

V It be iinderstoodithatathetermsand is used broadly- :thro'ughout thisede eri tlon material adapted 'for use in forming amold."

"It will also be understood that the termhollow; used throughout in a broadsense as: denoting merely that: the article'so qualified. is not solid but is so shaped as-to extend 'abti'n't, or-partially about, the matter in which it is inserted.

" The nails made accordingfito the above are durable, are cheap to manufacture and serve their purpose admirably. The nails inay be made .with great rapidity by inexpensive'machinery and it has been found in actual practice-in-making nails o'f'this type used than in'the case of wire nails. It will alithus be seen that the invention hereshown accomplishes, among others, 'the objects above enumerated. 7

-As many changes could be made in the above construction and many apparently widely difierent embodiments of this invention could be made without departing fromthe scope thereof, it. is intended that all -matter contained in the above description or shown in theaccompanying drawings shall interpreted as illustrative and not in a. :limiting sense. It is .alsofto be understood.

that the language used in the following claims-is intended to cover all of thegeneric .cla iin "as new and 1 ters atent is: in; I Wendycurved may and Specific features of the invention herein described,- and all statements ofthe scope of theinvention which, as a matter of lan gua-ge, might be saidj-to fall-therebetvyeen'.

Having described my invent-ion what I desire 'to secure Let- 1. A hollowmol an, flatghea'd formed to lie injaplane substantially at right angles tosaidbodv.

2. A mold *nail haying transversely curved body of substantially uniform *crosssection-throughout its length and a fiat head combination,

formed to lie in a plane substantially at v y right angles to said body. andt-he following claims tadenote any ose vlie in a'plane at an angle to the axis of the body.

5. The art of making a' mold winch comprises forming a sheet metal device into a shape havinga bend or curve and forcing said device into the sand-of the mold in the direction of the axis of said curve.

that the metal is ,far morev economically combination,- a sand mold, and a plurality of sheet metal devices lying within the sand of said mold and substantially normal to its inner surface. V

7.' In apparatus of the class'described, in a sand mold, and a plurality of stitfenin longitudina recess and lying within the sand of said mold adjacent its Inner surface.

8. In apparatus of the class described, in

combination, a sand mold, and a plurality of sheet metald'evices resting within the sand of said mold substantially normal 'to devices each provided ith a its inner surface and each formed to extend about-and embrace a portion of the sand. I 9. In apparatus of the class described, in combination, a sand mold, and aplurality of'sheet metal'devices eachhavinga tubu 'lar po rti'onresting within and ei'nbracing the sandwof the mold and having a head por tio n lying substantially flush with-the inner try; so of the mold; I stimo'ny whereof I afiix my signafth'e presence of two witnesses.
