MANUFACTURE OF ARMOR-PLATI'NG.
Specification of Letters Patent.
Patented Nov. 26, 1912.
Application filed August 1, 1912. Serial No. 712,690.
To all whom it may concern:
7' 7 Be it known that I, Enns'r FISCHER, en
gineer, citizen of Germany, subject of the King of Prussia and Emperor of Germany, residing at Dietrichsdorf, near Kiel, in the Kingdom of Prussia and Empire of Germany, have invented new and useful Improvements in the Manufacture of Armor- Plating, of which the following is a specification.
In the specification of my patent applica tion Serial No. 684496 of the 18th March 1912 a connection for armor plates is described which is established by pouring metal into recesses in the abutting portions of two adjacent armor plates. In this process owing to the large amount of heat supplied to the critical zone of the armor plates, that is to say where the hardened and in some cases welded-011 front stratum merges into the softer rear stratum, such tension may arise that the plate is endangered or its hardening may suffer.
The present invention has for its object to avoid or diminish this defect and resides in the fact that an insulating stratum, which may advantageously consist of nickel steel, is arranged in the recesses in the armor plates before the pouring in of the metal on the side which for metallurgical reasons is to be protected from large diiferences of temperature. By this means the technical effect not hitherto applied to armor plates is obtained that this protecting insertion absorbs a portion of the heat units of the poured material and also, owing to the transmission of heat from one contacting face to another a further retardation of the transmission of the heat to the critical zone is obtained while on the unprotected side the heat flows off unimpeded. By this means any danger to the armor plates from tensions in the welded or hardened surfaces is avoided. As after it has been poured in the material is no longer controllable as regards its strength and expansion, the inserted protecting strip with its controlled strength values serves as an exactly known portion of the tension joint because when the poured material contracts it is also firmly locked to the armor plates. When bronze s employed as the material to be poured 1n thls strip also prevents. it from coming into contact with sea-water and from corrosion by the latter.
In the accompanying drawing, Figures 1,.
to 3 illustrate embodiments of the invention in sections through two adjacent armor plates.
In the embodiment illustrated in Fig. 1 the abutting parts of the adjacent armor plat-es a and b are provided with undercut channels a. On one side of these channels a strip (Z advantageously of nickel steel, is inserted. The rest of the undercut channels is filled by pouring in material 0 such as bronze which contracts on cooling. The drawing shows that notwithstanding the relative displacement of the plates, which in reality is smaller than shown in the drawing, the insertion strip cl is rigidly connected with the plates by the poured material 0. In this manner the plates are anchored one to the other by a tension connection without risk of injury to the plate or its hardening when the contracting material is poured in.
Fig. 2 illustrates another solution of the problem. The recesses in the abutting parts of the armor plates a and b are here provided with reentering angles 0 which are filled by the poured material 0 and by which the tension connection is thus established. The insertion strip at is given a form corresponding to the recesses.
Another embodiment of the invention which is specially adapted for use for armor belt plates is shown in Fig. 3, where the two plates (0 and b are only protected by the poured material 0 against lateral displace ment. Such a connection is only made possible by the isolating strip d.
Having now particularly described and ascertained. he nature of my said invention, I declare that what I claim is 1. The combination with two abutting armor-plates each provided with a recess in the abutting portion thereof, a metal liner lining one side of the recesses, metal cast in the remaining portion of the recesses.
2. The combination, with two abutting armor-plates each provided with an undercut recess in the abutting portion thereof, a metal liner lining one side of the recesses, and a member composed of a material which shrinks when cooling cast in the remaining portion of the recesses.
3. The combination, with two abutting In testimony whereof I have hereunto set armor-plates eachprovidecl With a recess in my-hand in presence of two subscribing the abutting portion thereof, a metal llner Witnesses.
