S. P. HODGE. STAMP HEAD FOR QUARTZ GRUSHEBS.

SAMUEL F. HODGE, OF DETROIT, MICHIGAN,
IMPROVED STAMP-HEAD FOR QUARTZ-CRUSHERS.
Specification forming part of Letters Patent No. 83,993, dated December 24,1861.
To all whom it may concern:
Be it known that I, SAMUEL F. Honen, of Detroit, in the county of Wayne, in the State of Michigan, have invented a new and Improved Method of Making Stamp-Heads for Stamping-Mills or Quartz-Crushers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon.
My invention relates to a novel and improved mode of making stamp-heads, the stamp-head being constructed in any of the known forms now in use.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
For the purposeof casting my stamp-head I use a mold or matrix like those ordinarily used by furnace-men, placing therein vertically a number of cast-steel or wrought-iron bars, so that the ends of said bars shall be presented vertically to the wearing-surface or working-face of the stamp-head, as represented in the drawings. These vertical bars are so set in the mold that when the cast-iron is flowed around them the bars will be separated from each other a sufficient distance to permit of valleys or corrugations or undulations or honey-comb cavities to be formed between the said bars by reason of the gradual wearing'away of the cast-iron Working-face of the stamp-head, due to its use, and to secure the bars permanently in place within the cast-iron portion of the stamp-head, screwthreads, previous to their insertion within the mold, may be cut around their ends opposite their Working-face, thus preventing their becoming loose and working out of the body of the stamp-head after the cast-iron has once become cooled and set around them. By this combination of cast-iron with cast-steel or wrought-iron bars a stamp-head is produced which is far more effective in the reduction of ores than the ordinary stamp-heads now in use, which are made of cast-iron entire, whether chilled or not, or entirely of steel, and which by reason of their construction present an uninterrupted plane working-surface to the ore. It is obvious that by making the bars of a softer metal than the main portion or body of the stamp-head the same effeet will in a measure be produced.
All stamp-heads as now made have a tendency to wear away more at the corners and edges than in the mi(ldle,so that the working-face soon becomesrounded and inefficient,
whereas in my stamp-head the steel bars are Fig. 2, an end view of same, and Fig.3 a plan of the working-face.
S S S are the steel or wrought-iron bars. I
is the cast-iron which surroundsthem.
I disclaim the construction of stamp-heads when made entire of cast-iron, whether made in one piece orin sections and whether chilled or not, and I also disclaim the making of stamp-heads entirely of steel, and whether made in one piece or consisting of a cluster of cast-steel rods.
lVhat I claim as my invention, and desire to secure by Letters Patent of the United States, is-
The construction of stamp-heads for crushing ores of two metals, one of which is of greater durability than the other, the two metals bearing the relation to each other de-' scribed, so asto wear away unequally on the working-face of the stamp-head, and thus insure the gradual production otan undulating, corrugated, or honey-comb crushing-face.
