DIE.
To all whom ''t may concern:
Be it known that I,. Gnonen ALBERT J own,
a subject of the King of Great Britain and Ireland,';and a resident of London, count of Middlesex, England, (temporarily resi ing at the borough of Brooklyn, New York city,
in the county of Kingsan'd State of New York,) have invented certain new and useful Improvements in Dies, of which the followingis a specification. The present invention relates to dies, and as more particularly reference to dies t rough which tungsten or other material is expressed.
When mounting a drilled diamond or stone by casting-steel around the same, the steel block thus formed takes up the great pressure used in expressin the tungsten through the die. It 18 well nown that the excessive heat of the molten steel and its subsequent contraction when coolin has an injurious eife'ctupon a' diamond W ich has been deprived of its natural skin'in the process of bein drilled.
Th'main object of the present invention is to mount a diamond or-other die member without exposing it to excessive heat.
Accordingly the invention consists in a mount com osedof a plurality of parts in which the ie is seated, the saidparts being v preferably welded together to form a protecting mount. made of a material having a high tensile strength and a relatively hi h meltingpoint, such as wrought steel. n thepreferred embodiment of the invention the mount is composed of a supporting member, having a die chamber and a bore leading therefrom, and a top plate provided with a bore leading to the die chamber. The die member is seated in the die chamber andis held in position with reference to the'bores of the mount by means of a body of material havin a relatlvely low melting point such as she lac, a composition of vgax or other m terial such as bronze. The casting of this body of material around the stone can be done at so low a temperature that it will. not injure the diamond. The supporting member and top plate are welded to ether at a point remote from the die cham er so that the heat will not affect the stone or melt the body of composition holding the stone in place. Preferably the two parts of the mount are provided with complementary pins and apertures, the pins ex- The mount is preferably.

tending through the apertures to the outside of the mount, at which point the parts thereof are welded together.
The invention further consists in the method of making a die which consists in seating a die in the die chamber of one part of a mount, preferably by means of a body of material having arelatively low melting point, and then welding the two parts of the mount together.
" Other features will appear as the specification proceeds.
In the drawings the invention is embodied in a concrete and preferred form, but changes may of course be made without departing from the legitimate and intended scope of the invention, as expressed in the claims hereof.
In the said drawin s: Figure 1 is a vertical sectional view of the supporting member showing the diamond in position and the body of material cast around the diamond to hold it in position. Fig. 2 shows the top plate in position on the supp ing member, the view bein vertical in cross section.
Fig. 3 shows the nished product after the parts are welded together, this view being ikewise in vertical cross section. Fig. 4 shows a modification.
Similar characters of reference indicate corresponding arts in the different views.
1 indicates t e supporting member of the mount made of wrought steel and provided with the die chamber 2, extending downs wardly from its upper surface 3.
The bore leading from the die chamber is shown at 4, and 5 indicate pins rising er surface 3 of the said sup-- from the up porting mem er.
The drilled diamond or die is indicated at 6. This is placed in the die chamber 2 and a body of bronze or other material 7 is cast around the said'stone, which latter is held ose contact with the diamond and provided with the bore 10 leading to the die chamber and hav-v ing the apertures 11 into which the pins 5 extend. These pins extend clear through the apertures. I
The two parts of the mount are welded together by a plying heat, electrical or otherwise, loca y to the pins which will then fuse. Heat may also be applied locally at the meetingedges of the two parts of the mount circumferentially around the line in- ,of the invention. In this view the dicated by 12. After the parts are welded- 1-. In a die, a mount of a material of hi h tensile strength and a relativel high mel ing point, having a die cham er and 0p posl te bores leading thereto, said mount consisting of a plurality of parts welded together at a point remote from the die chamher, a die member seated in said chamber,
and a body of material of a relatively low' meltingpoint surrounding said die member in the chamber and holding it in alinement with the bores aforesaid. i
2. In a die, a mount of a material having a relatively high melting'point, and having a die chamber and opposite bores leading thereto, said mount consisting ofa. plurality of parts welded together at a polnt remote from the die chamber, a die member seated in said -chamber, and a body of material of a relatively low melting point surrounding said die member in the chamber and holding it in alinement with the bores aforesaid. 1
3. In a die, a steel mount having 0 posite bores leading to a die chamber an composed of a plurality of mas welded a.
gether,a drilled stone seated in said chain ber, and a body of compositionfor holding said stone insaid chamber. 4. The process of making a die'whichconsists in seating a drilled st0newit hin,the'.
chamber of a supporting member of a mount by casting a body of material having a lower melting point than that of which the mount. is composed into said chamber around the.
stone, and then Welding a top plate on the a v supporting member.
5. The process of making a' die which consists in seating adrilledstone within the chamber of a steel supporting member by casting a bodyof material having a lower melting point thanthat of steel into said chamber around the stone, and then welding a top, plate of steelon the supporting member.
6. Ina die, a mount consisting of a supporting member and a top plate, said supportmg member having a die chamber extending downward from its upper surface, a
drilled stone seated in said die chamber, abody of material of relatively low melting point surrounding said stone in said chamher and the top plate resting on the sup-' porting member and forming close contact with the stone.
