HENRY BOLTHOFF,v OE CENTRAL CITY, COLORADO TERRITORY.
Letters Patent No. 108,556, dated october 25, 1870.
IMPRovEMEN'r lN FLAsKs Fon CASTING STAMP-SHOES Fon cRusl-uNG-MILLS.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, HENRY BoLTHoFF, of Cen.- tral City, Gilpin County, Colorado Territory, have invented a new and Improved.MoldingFlask for the Manufacture of Stamp-Shoes and Dies for Stamps or f Crushing-Mills, by means of Screw-Pressure; and I do hereby declare that the following is a tiill and exact description thereof', reference being had to the accompanying drawings,and to the letters of reference marked thereon.- p
The nature of my invention consists in exerting screw-pressure upon the iron when in a molten state,
by means of a screw, as shown at A in the accompanying-drawings. This pressure is continued until the iron becomes chilled or hard.
By means of this pressure, the iron of the shoe or die is rendered much more dense and durable than by packed with sand, representedby D, which sand serves the double'purpose of supporting the cover C when the pattern is withdrawn, and also for faeilitatin g the removal of the shoe or die when cast.
The upper portion, E, of the flask is secured to the .the neck of the shoe, to any length required.
lower-'portion `or chill, F, ot' the flask, by means of the key at I. Y
G is a movable plug, which can be easily raised or lowered for the purpose of lengthening or shorte'rlxilng ns plug is fastened at any given point, by means of a thumb-screw, v
The iron is poured into the tlask through the groove or spout at K t On the under side of the cover C, and at D, by refereneeto the drawings, is a teat, or prominence, which is designed to produce a concave on the bottom of the shoe, which will prevent the shoe from wearing to a pointwhen placed on an old die having an irregular surface.
A shoe manufactured in this tiask will be perfectly smooth and regular in form, making it easily and perfectly adjustable to the stern, thus diminishing the' liability of breaking on account of imperfect adjustnient. Besides, these shoes and dies will wear nearly twice as long as the ordinary shoes and dies on account of the greater density given to the iron by screwpressure exerted in the manner above described.
\Vh4at I claim` as my invention, and desire to secure by Letters Patent, is-l A flask, constructed and arranged as described. AWitnesess: HENRY BOLTHOFF.
