Description

UNITED STATESA PATENT OFFICE.
CHRISTIAN F. KNAUER AND WM. WARWICK, OF PITTSBURG, PA.
IMPROVED SAD-I RON.
Specification forming part of Letters Patent No. 56.764, dated July 31, 1866.
To all 'whom it may concern Be it known that We, CHRISTIAN F. KNAUER and WILLIAM WARWICK, of Pittsburg, in the countyoi'1 Allegheny' and State of Pennsylvania, have invented a new and Improved Mode in the Manufacture of SadIrons; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawin gs, and to the letters of reference marked thereon, making part of this specication, in which- Figure l is a perspectiveview of a linished sad-iron; Fig. 2, a top view of an open sand mold when the patterns are withdrawn; Fig. 3, face and edge view of a wrought-iron chillplate which is inserted in the mold.
Similar letters of reference indicate correspending parts.
The nature of our invention consists in simplifying the process of manufacture.
The solidifying of the fluid metal toward the face of the sad-iron by inserting a chill quickens the crystallization on its face, and therefore the casting will be more compact, and will, when `nished, resemble polished steel; and, further, the inclined shape given to the handle will give a more natural motion to the arm of the operator, as done by the handle of the carpenters plane;
To enable others skilled in the art to make and use our invention, We will proceed to describe i'ts mode of construction and operation.
Two patterns of sad-irons are molded in the manner shown in Fig. 2, face to facethat is, the irons are laid in the sand mold horizontal with the central longitudinal line of body A and handle B, the double face of the chill D forming a rectangular or perpendicular line with the former. This horizontal line parts top and bottom flask, leaving half the impression above and below. When the molder has completed his Work in the usual manner, he
lifts off the cap of the flask, withdraws the patterns, leaving the chill D in the sand mold, which is, for the purpose of supporting itself and to resist the pressure of the molten metal,
cast-iron, as is well known. It also retains on the face the exact fac-simile of the chill-face, and therefore reduces the labor of grinding,
\ as the luster of tl1e.metal is soon reached. It
receives a very high polish, resembling steel, which is much admired, and never could be attained by the common method of casting.
The advantages of our invention will be more clearly understood by alluding to the old process for the manufacture of sad-irons, viz: First, a piece of wrought-iron is cut in proper length to form the handle; second, the handle or gripe is cast thereon; third, is then bent to its required shape; fourth, the body of the iron is cast thereon. In our invention We dispense entirely with the second and third operation. Thereby a large saving is made in the manufacture of this important article.
What we claim, and desire to secure by Letters Patent, is-
The method of constructing sad-irons, substantially as herein specified and set forth.
CHRISTIAN F. KNAUER. WM. WARWICK.
