ALBERT Ll lTTGrES, OF SOLINGEN, FRUSSIA, GERMANY.
IMPROVEMENT lN APPARATUS FOR HARDENING AND TEMPERING SHEET-STEEL.
Specification forming part of Letters Patent No. 198,804, dated January 1, 1878; application filed September 29, 1877.
To all whom it may concern:
Be it known that I, ALBERT Lt 'rrens, of Solingen, in the Kingdom of Prussia and Empire of Germany, have invented a new and improved Apparatus for Hardening and Tempering Sheet-Steel, of which the following is a specification:
In the accompanying drawings, Figure 1 represents a top view; Fig. 2, a vertical longitudinal section on line as m, Fig. 1; and Figs. 3 and 4 are vertical transverse sections, re-
spectively, on lines y y and c c, Fig. 2, of my improved apparatus for hardening and tempering sheet-steel.
Similar letters of reference indicate corresponding parts.
The invention consists of an apparatus for the purpose of conducting, first, the sheetsteel through a heating-oven; then hardening the same between cooling-vessels, that are pressed thereon withmore or less power; and, finally, tempering the sheet-steel by passing it between the bridge of a box heated by charcoal or otherwise and ablockpressing thereon. Referring to the drawings, A represents an oven, that is heated up by a fire below the same, and through which the sheet-steel is conducted by means of end openings, the steel having been previously rolled up on a drum, B.
The sheet-steel is thoroughly heated in the oven, and then passed through between a fixed and a movable chilling-vessel, 0, arranged near the exit-openings of the oven, the vessels being kept cool by a continuous flow of cold'water.
The water-supply is kept up by means of entrance and discharge pipes, and by the the pressure of the reservoir on the steel may v be regulated at will. The sheet-steel is then conducted over an iron bridge, E, of a castiron box, E, heated by burning coke or charcoal, or in other suitable manner.
The temper of the steel is drawn by its passage between. the heated plates. The sheetsteel is exposed to the pressure of a weighted lever, E that is connected to a top block, F, which exerts a greater or less pressure on the sheet-steel during its passage over the bridge.
The tempered steel is wound up on a drum, G, that is turned by suitable crank and gearing. At the beginning of the operation the end of the sheet-steel is drawn through the apparatus by a chain attached thereto, the hardening and tempering being continued in regular manner after the en d is drawn through the oven hardening and tempering devices.
Having thus described my invention, I claim as. new and desire to secure by Letters Patent In an apparatus for hardening and tempering steel, the combination of a heated tempering-box, having a top guide-bridge, with a pressure'block and weighted lever connected thereto, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 25th day of June, 1877.
