The general object ofmy present invention is the provision of a method of pro-' ducing relief maps, and this in such manner that the maps produced are accurate in character and are calculated to give good ideas at a glance of the terrains mapped.

The invention consists in a peculiar and advantageous relief map producingprocess. With the foregoing in mind the invention will be fully understood from the following description and claims when considered in connection with the accompanying drawings, forming part of the specification, in which:-

Figure 1 is a plan view illustrative of the initial steps ofmy novel process. V Figure 2 is a vertical section taken in the plane indicated by the line 22 of Figure 1, with the embossing element in elevation and also shown by dotted lines in different positions.

Figure 8 is a plan view illustrative of the second step of my novel process.

Figure 4 is a section taken in the plane indicated bythe line 44 of Figure 3, dotted lines being employed to represent the embossing element in different positions.

Figure 5 is a vertical section illustrative of my novel relief map as the same appears when completed, said section being taken in the plane indicated by the line 5-5 of Figure 6.

Figure 6 is a top plan view of said relief map.

Figure 7 is a side elevation of the relief map.

Figure 8 is a fragmentary section illustrative of the manner in which an area within the limits of a contour line is embossed to the predetermined depth or scale.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

I show in Figures 2 which is disposed a base 4 of sand or other approved yielding material.

In carrying out my process I position a sheet 2 of ductile metal on the container 3 and over the said base 4, the sheet being ar- 50 ranged face downward as will be manifest and 4 a container 3 in from Figures 2 and 4. The sheet 2 alluded to is characterized by the representation on the back side thereof of one or more contours, and in the illustrated example of a plurality of contours the outer line of the outer contour is designated by 5 in Figures 1 and 3, and the outer line of the next inner contour is designated by 6 in Figure 3. It 'will also be noted that legends are provided on the back side of the sheet, Figure 8, indicative of the heights to which the contours are to be embossed; the legend 100 by way of example being placed adjacent the outer line 5 of the outer contour, and the legend '200 being placed, by Way of example, adjacent to the outer line 6 of next highest embossment.

At 1 in Figures 1 and 2 is the handle of an embossing element 7, said embossing element being illustrated by full and dotted lines in Figure 2, by full lines in Figure 1, and thehead of said element being represented by dotted lines in various positions in Figure 4. This application is filed in the place and stead of my contemporary application Serial N 0. 544,933, and within the purview of my invention'the embossing element may be of any approved character as, for example, the embossing element comprised in the apparatus constituting the subject of my application filed June 12, 1931, Serial No. 543,926,. patented May 31, 1932, N 0. 1,860,729.

It will be understood from the foregoing that when first placed over the yielding base 4 the sheet 2 is in a straight and flat state bearing the contour representation and by preference the legends hereinbefore referred With the sheet 2 positioned as stated and secured in said position, if necessary, my process is as follows First by blows of the embossing element, the metal is displaced within the line 5 and throughout the area of the contour to the de th indicated by 7a; in Figures 2 and 4.

econd. A portion of the initially displaced metal is similarly displaced, within the line 6, to the greater depth indicated by 800 in Figure 4.

The steps or similar steps are repeated until the sheet is reduced to the shape shown in Figures 5, 6 and 7.

The corners between the several layers of the sheet of metal are designated by 5a, 6a, 1O, 11, and 12 in Figures 5 to 8, inclusive, and manifestly said corners constitute contours.

The essence of my invention lies in the expeditious production of a relief map that is at once accurate and calculated to impart at a glance an adequate understanding of the character of the terrain mapped.

Manifestly the expedition with which an accurate relief may may be produced in accordance with my invention will be materially advantageous in war time when armies are in motion and unless a map can be quickly produced its production is likely to be too late.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is 2-- 1. A relief map producing process comprising representing on one side of a sheet of ductile metal a series of contours, and embossing the series of contours one after the other until the highest elevation is reached to proportionately represent hills or hill portions of different heights in relief at the opposite side of the sheet; the lowest elevation being embossed throughout the area of and within the outermost contour, and the next highest elevation being embossed throughout the area of and within the 'con-' tour next to the outermost contour and by displacing part of the metal initially dis placed for the representation of the lowest elevation.

2. A relief map producing process comprising representing on one side of a sheet of ductile metal a series of contours and also placing on said side adjacent the contours height-indicating legends, and embossing the series of contours one after the other according to said legends to scale until the highest elevation is reached to proportionately represent hills or hill portions of different heights in relief at the opposite side of the sheet; the lowest elevation being embossed throughout the area of and within the outermost contour, and the next highest elevation being embossed throughout the area of and withm the contour next to the outermost contour and by displacing part of the metal initially displaced for the representation of the lowest elevation.

3. A relief map producing process com prising representing on one side of a sheet of ductile metal a series of contours, and embossing the series of contours one after the other until the highest elevation is reached to produce corners constituting contours and to proportionately represent hills or hill portions of difi'erent heights in relief at the opposite side of the sheet; the lowest elevation being embossed throughout the area of and within the outermost contour, and the next highest elevation being embossed throughout the area of and within the contour next to the outermost contour and by displacing part of the metal initially displaced for the representation of the lowest elevation.

4. A relief map producing process comprising representing on one side of a sheet of ductile metal a series of contours and also placing on said side adjacent the contours height indicating legends, and embossing the series of contours one after the other according to said legends to scale until the highest elevation is reached to produce corners constituting contours and to proportionately represent hills or hill portions of different heights in relief at the opposite side of the sheet; the lowest elevation being embossed throughout the area of and within the outermost contour, and the next highest elevation being embossed throughout the area of and within the contour next to the outermost contour and by displacing part of the metal initially displaced for the representation of the lowest elevation.

In testimony whereof I afiix my signature.
